No. 14/514,776 entitled “METHODS AND APPARATUS FOR ASSISTED RADIO ACCESS TECHNOLOGY SELF-ORGANIZING NETWORK CONFIGURATION” filed Oct. 15, 2014, which claims priority to U.S. Provisional Application No. 61/975,574 entitled “METHODS AND APPARATUS FOR ASSISTED RADIO ACCESS TECHNOLOGY SELF-ORGANIZING NETWORK CONFIGURATION” filed Apr. 4, 2014, and assigned to the assignee hereof. This application incorporates by reference the entireties of those applications. 
    
    
     BACKGROUND 
     Aspects of the present disclosure relate generally to wireless communication, and more particularly, to methods and apparatus for assisting radio access technology self-organizing network configuration. 
     Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, etc. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Examples of such multiple-access networks include Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, Orthogonal FDMA (OFDMA) networks, and Single-Carrier FDMA (SC-FDMA) networks. 
     A wireless communication network may include a number of eNodeBs that can support communication for a number of user equipments (UEs). A UE may communicate with an eNodeB via the downlink and uplink. The downlink (or forward link) refers to the communication link from the eNodeB to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the eNodeB. 
     In some wireless communication networks, a user equipment (UE) selects and maintains a connection with a base station providing communication capabilities for the UE. Further, in such wireless communication systems, small cells are deployed to improve wireless network communications when experiencing poor base station (e.g., Home Node B) connections. In such wireless communication networks, inefficient utilization of available communication resources, particularly identification resources for cell configurations, may lead to degradations in wireless communication. Even more, the foregoing inefficient resource utilization inhibits network devices from achieving higher wireless communication quality. In view of the foregoing, it may be understood that there may be significant problems and shortcoming associated with current self-organizing network configurations. Thus, improvements in self-organizing networks are desired.

     DETAILED DESCRIPTION 
     The detailed description set forth below, in connection with the appended drawings, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known components are shown in block diagram form in order to avoid obscuring such concepts. In an aspect, the term “component” as used herein may be one of the parts that make up a system, may be hardware or software, and may be divided into other components. 
     The techniques described herein may be used for various wireless communication networks such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other networks. The terms “network” and “system” are often used interchangeably. A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network may implement a radio technology such as Global System for Mobile Communications (GSM). An OFDMA network may implement a radio technology such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunication System (UMTS). 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are new releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization named “3rd Generation Partnership Project” (3GPP). cdma2000 and UMB are described in documents from an organization named “3rd Generation Partnership Project 2” (3GPP2). The techniques described herein may be used for the wireless networks and radio technologies mentioned above as well as other wireless networks and radio technologies. For clarity, certain aspects of the techniques are described below for LTE, and LTE terminology is used in much of the description below. 
     The present aspects generally relate to the use of a wireless local area network (WLAN) to assist in the configuration of wireless wide area network (WAN or WWAN) self-organizing network (SON). SON may simplify and automate the initial provisioning, in operation optimization, and maintenance of mobile networks. However, in some wireless communication systems, WAN-configured SON entities deployed in dense communication environments may experience difficulties in obtaining a number of measurements used for SON. For example, a WAN entity such as a small cell communicating according to long term evolution (LTE) may find it difficult to obtain certain measurement information from a user equipment (UE). 
     Specifically, in dense communication environments comprising a number of small cells, a WAN entity (e.g., associated with/used for an LTE SON) at a small cell may be operating using the same or similar time/frequency characteristics as a WAN entity at one or more neighboring small cells. Hence, such dense communication environments may exhibit higher levels of interference due to, for instance, pilot pollution by the WAN entities of the one or more small cells. For example, if there are more than two cells (besides the strongest cell) within a certain frequency of the strongest cell then there is pilot pollution. Accordingly, the UE may be unable to obtain reliable measurement information for subsequent transmission to a WAN entity (e.g., LTE SON). Even more, in multi-radio access technology (RAT) small cell deployments employing collocated WAN and WLAN (e.g., Wi-Fi) entities, the WLAN entity, although capable of transmitting and receiving measurement information to and from the UE, such information, which may be particularly useful to the WAN entity for interference management and/or SON purposes, may nonetheless be neglected for such purposes. 
     Accordingly, in some aspects, the present methods and apparatus may provide an efficient and effective solution, to provide a WLAN-assisted WAN SON entity at one or more small cells employing collocated WLAN and WAN entities. In an aspect, the present apparatus and methods may provide an assisted WAN SON solution by utilizing a collocated WLAN entity to receive measurement information from a UE. The measurement information may correspond to or otherwise be indicative of UE measurements of one or more WLAN communication characteristics. For example, the WLAN entity may transmit a beacon signal/indication to assist with WLAN locating and connection. The UE may measure a signal strength metric of the beacon signal/indication such as, but not limited hereto, a received signal strength indicator (RSSI) to determine, among other communication characteristics, the pathloss between the WLAN entity and the UE. 
     For example, the UE may not be able to detect the WAN entity of a small cell directly due to high interference from WAN entities of other small cells using the same or similar time and/or frequency resources. Further, the UE may readily detect WLAN entity collocated with the WAN entity at the small cell as the WLAN entity may operate in an unlicensed band which has multiple frequencies that help reduce interference. Moreover, WLAN medium access control (MAC) entity may use carrier sensing multiple access (CSMA), which may enable listen-before-talk aspects to reduce a collision probability between WLAN entities. 
     Additionally, the present aspects may include a WLAN entity which may embed RAT entity-specific information in the one or more beacon indications, such as, but not limited to, a load level value of the WAN entity, a number of serving UEs, quality of service information, carrier type information, scheduling information, priority level information, allowable interference level value, coexistence parameters such as power backoff, time division multiplexing (TDM) and/or frequency division multiplexing (FDM) configuration, fractional frequency reuse configuration, and one or more mobility related parameters. The RAT entity-specific information may be used for interference management, mobility management, and/or self-configuration by the WAN SON entity (e.g., transmission power adjustment and/or resource adjustment). 
     In other words, the present aspects may embed RAT entity-specific information corresponding or otherwise related to a second RAT entity (e.g., WAN entity) into a first RAT entity beacon. As such, the UE may then provide corresponding measurement information for use in subsequent WAN SON entity assisted determinations. In other aspects, a WLAN entity of a neighboring small cell may detect and provide measurement information to the WLAN entity of the small cell responsible for embedding the RAT entity-specific information. Specifically, in one example, a pathloss of the WAN entity may be determined based at least in part on the pathloss of the first RAT entity (e.g., WLAN entity) and a correction factor value. In such aspects, the correction factor value may be a function of at least a frequency of the second RAT entity (e.g., WAN entity). As such, the present apparatus and methods provide a WLAN assisted solution for assisting with interference management at a second RAT entity in dense small cell environments. 
       FIG. 1  is a block diagram conceptually illustrating an example of a telecommunications network system  100  in accordance with an aspect of the present disclosure. Telecommunications network system  100  may include one or more network entities  110 , for example, one or more small cells. As used herein, the term “small cell” may refer to an access point or to a corresponding coverage area of the access point, where the access point in this case has a relatively low transmit power or relatively small coverage as compared to, for example, the transmit power or coverage area of a macro network access point or macro cell. 
     For instance, a macro cell may cover a relatively large geographic area, such as, but not limited to, several kilometers in radius. In contrast, a small cell may cover a relatively small geographic area, such as, but not limited to, a home, a building, or a floor of a building. As such, a small cell may include, but is not limited to, an apparatus such as a base station (BS), an access point, a femto node, a femtocell, a pico node, a micro node, a Node B, evolved Node B (eNB), home Node B (HNB) or home evolved Node B (HeNB). Therefore, the term “small cell,” as used herein, refers to a relatively low transmit power and/or a relatively small coverage area cell as compared to a macro cell. 
     Each small cell  110  (e.g., small cell  110   y ) may include SON component  130 , which may be configured to autonomously manage interference that arises because of signals from two or more small cells. Further, for instance, SON component  130 , which may be included in each small cell  110  illustrated in  FIG. 1 , may be configured to receive measurement information at a first RAT entity. In other words, SON component  130  may be configured to manage interference at a second RAT entity (e.g., WAN entity  138 ) based on measurement information received at a first RAT entity (e.g., WLAN entity  136 ). Such interference management may be accomplished by one or both of first management component  132  and second management component  134 . 
     Additionally, small cell  110   y  may be configured to facilitate communication with a network via two or more wireless RAT protocols. In other words, small cell  110   y  may be configured to include both a first RAT entity in the form of WLAN entity  136  and a second RAT entity in the form of WAN entity  138 . Hence, small cell  110   y  may, in some aspects, communicate according to a multi-RAT scheme. In some aspects, WAN entity  138  may include a radio that communicates according to at least one technology such as, but not limited to, long term evolution (LTE), universal mobile telecommunications system (UMTS), code division multiple access (CDMA)  2000 . In additional aspects, WLAN entity  136  may include a radio that communicates according to at least one technology such as, but not limited to Wi-Fi. 
     Further, one or both of WLAN entity  136  and WAN entity  138  may be configured to perform autonomous functions according to SON mechanisms. For instance, WAN entity  138  may alternatively be referred to as a WAN SON entity  138 , which may be configured to self-organize according to a distributed, centralized, and/or hybrid architecture. In some aspects, WAN entity  138  may be alternatively referred to as a WLAN-assisted WAN SON entity  138 . Moreover, WAN entity  138  may be configured to function according to one or more of a self-configuration function, self-optimization function, and self-healing functions, all of which enable WAN entity  138  to plan, configure, manage, optimize and heal in an automated and effective manner. 
     Referring to first management component  132 , an aspect of which may include various components and/or subcomponents which may be configured to manage interference at a second RAT entity (e.g., WAN entity  138 ) based on measurement information received at a first RAT entity (e.g., WLAN entity  136 ). Specifically, in such aspects, first management component  132  may be configured to receive, at first RAT entity (e.g., WLAN entity  136 ) measurement information from UE  120   y  for assisting with interference management at second RAT entity (e.g., WAN entity  138 ). For example, UE  120   y  may be in an environment demonstrating high levels of pilot pollution, and thereby limiting UE  120   y  from obtaining accurate measurement information associated with second RAT entity. 
     In some aspects, SON component  130  and/or UE  120   y  via measurement component  140  may determine or identify that the environment demonstrates high levels of pilot pollution. As such, in aspects where the first RAT entity may be collocated with the second RAT entity, that is, where WLAN entity  136  may be collocated with WAN entity  138 , the first RAT entity, or WLAN entity  136 , may be configured to assist WAN entity  138  by receiving and processing measurement information from UE  120   y . In such aspects, although WAN entity  138  may be capable or configured to obtain these measurements from UE  120   y , the environment may preclude WAN entity  138  from receiving accurate results from UE  120   y.    
     For example, the air interface corresponding to WAN entity  138  may not allow the embedding and transmission of RAT entity-specific information to UE  120   y  or another small cell (e.g., small cell  110   z ). Accordingly, WLAN entity  136 , which may not be experiencing poor or diminished communication quality with or otherwise between UE  120   y , may receive more accurate measurements results (e.g., measurement information) from UE  120   y . Additionally, WAN entity  138  may be capable of or configured to determine when to use or process the measurement information received from WLAN entity  136 . In such aspects, WLAN entity  136  may be configured to receive measurement information on a periodic basis. 
     In further aspects, first management component  132  may be configured to arrange or otherwise configure the second RAT entity (e.g., WAN entity  138 ) based at least in part on the measurement information received by the first RAT entity (e.g., WLAN entity  136 ). Specifically, the measurement information may include a pathloss value determined based at least in part on one or both of a signal strength value and a transmit power value of one or both of the first RAT entity and the second RAT entity. In some aspects, the signal strength value comprises a received signal strength indicator (RSSI) value. As such, WLAN entity  136  and/or UE  120   y  may be configured to determine a pathloss value of the second RAT entity (e.g., WAN entity  138 ) based at least in part on the pathloss value of the first RAT entity (e.g., WLAN entity  136 ) and a correction factor value. In such aspects, the correction factor value may be a function of at least a frequency and/or frequency band of the second RAT entity (e.g., WAN entity  138 ). Additionally, the correction factor may include a transmission power value and an antenna gain value of one or both of WLAN entity  136  and WAN entity  138 . 
     In additional aspects, first management component  132  may be configured to transmit, using the first RAT entity (e.g., WLAN entity  136 ), a management indication to trigger UE  120   y  to determine the measurement information by performing one or more measurements on or at the first RAT entity. In other words, the WLAN radio of small cell  110   y  may be configured to transmit a management indication in the form of a beacon indication to trigger UE  120   y  to measure at least the signal strength (e.g., RSSI) of, or corresponding to, the beacon indication. In such aspects, the transmission of the beacon indication to UE  120   y  may be made periodically. 
     In such aspects, the beacon indication transmitted by the WLAN entity  136  may alternatively be referred to as a beacon frame, which may be a type of management frame, and transmitted periodically to enable WLAN entities and/or UEs to establish and maintain communications in an orderly fashion. For instance, a beacon frame may be a management frame in IEEE 802.11 based WLANs and may include information about the network. In some aspects, a beacon&#39;s frame body may reside between a header and a cyclic redundancy checking (CRC) field and constitutes the other half of the beacon frame. 
     Each beacon frame may carry or include information in the frame body including, but not limited to, a timestamp, a beacon interval, capability information, a service set identifier (SSID), supported rates, a frequency-hopping (FH) Parameter Set, a direct-Sequence (DS) Parameter Set, a contention-Free (CF) Parameter Set, an MSS Parameter Set, and a traffic indication map (TIM). For example, the beacon indication may include an SSID such as an SSID of another first RAT collocated with another second RAT. 
     Further, an aspect is described of second management component  134  which may include various components and/or subcomponents that may be configured to manage interference at a second RAT (e.g., WAN entity  138 ) based on measurement information received at a first RAT (e.g., WLAN entity  136 ). Specifically, in such aspect, second management component  134  may be configured to receive, at the first RAT (e.g., WLAN entity  136 ), a request indication from the UE  120   y  (e.g., probe request indication) for triggering transmission of a management indication (e.g., probe response indication). In some aspects, a management indication may take the form of, or be similar to a probe request, which may be used to actively seek any, or a particular access point or BSS, such as WLAN entity  136 . Additionally, a management indication may be a reply with station parameters and supported data rates, and/or may include at least some information associated with the beacon indication described herein. 
     Further, second management component  134  may be configured to embed, by a first RAT (e.g., WLAN entity  136 ), RAT-specific information of a second RAT (e.g., WAN entity  138 ) in the management indication. In such aspects, the first RAT and the second RAT may be collocated entities. Additionally, second management component  134  may be configured to transmit the management indication to UE  120   y . In such aspects, the management indication may allow UE  120   y  to obtain similar measurements as a transmitted management indication (e.g., beacon indication). 
     That is, a management indication may enable UE  120   y  to obtain at least a corresponding signal strength value for pathloss determination of one or both of first RAT and second RAT. In some aspects, management indication may include or take the form of a probe response signal/indication, a beacon indication, or any broadcast indication, each of which may be associated with WLAN entity  136 . In other aspects, measurement information associated with the transmission of a broadcast indication may be received directly by second RAT entity (e.g., WAN entity  138 ) or via UE  120   y.    
     In some aspects, the RAT entity-specific information of the second RAT may include one or more of a load level value, a number of serving UEs, quality of service information and carrier type information. In some aspects, the carrier type information may include information relating to a number of carriers at the small cell, an indication of whether carrier aggregation is supported at the small cell for one or both of WLAN entity  136  and WAN entity  138 , an indication of whether WAN entity  138  supports or communicates according to an unlicensed spectrum technology, and the channels and/or bands utilized at the small cell in one or both of the licensed and unlicensed spectrums at WAN entity  138 . In additional aspects, second management component  134  may be configured to embed the RAT-specific information in a reserve field of a probe response indication. Additionally, in other aspects, the RAT-entity specific information may include scheduling information for one or more of the serving UEs. In such aspects, the scheduling information may include time and/or frequency resources. Further, the RAT-entity specific information may include an indication of whether a UE is a cell edge or cell center UE. 
     Referring to measurement component  140 , which may be included, implemented, or embodied within UE  120   y , an aspect is described which may include various components and/or subcomponents which may be configured to assist in the management of interference at a second RAT (e.g., WAN entity  138 ) based on measurement information transmitted to a first RAT (e.g., WLAN entity  136 ). Specifically, in such aspects measurement component  140  may be configured to measure a signal strength value corresponding to a management indication received from a first RAT (e.g., WLAN entity  136 ) for assisting with interference management at a second RAT (e.g., WAN entity  138 ). Further, measurement component  140  may be configured to transmit measurement information to the first RAT for use in configuration of the second RAT. 
     For example, measurement component  140  may be configured to determine a pathloss value of the first RAT (e.g., WLAN entity  136 ) based at least in part on one or both of the signal strength value (e.g., RSSI) and a transmit power value of one or both of the first RAT and the second RAT. Additionally, upon obtaining and/or determining the pathloss associated with WLAN entity  136 , measurement component  140  may be configured to determine a pathloss value of the second RAT (e.g., WAN entity  138 ) based at least in part on the pathloss value of the first RAT and a correction factor value. In some aspects, the correction factor value may be a function of at least a frequency of the second RAT. 
     In further aspects, the measurement information may include one or more of the pathloss value of the first RAT, the pathloss value of the second RAT, a load level value, a number of serving UEs, quality of service information and carrier type information. As such, UE  120   y  may be configured to provide measurement information in addition to a pathloss value according to a request or instruction from WLAN entity  136 . Moreover, measurement component  140  may be configured to identify the first RAT entity (e.g., WLAN entity  136 ) collocated with the second RAT entity (e.g., WAN entity  138 ) based at least in part on one or both of an SSID or a basic serving set identifier (BSSID) obtained from the management indication. In certain instances, the SSID may be configured to maintain packet information within the correct WLAN, even when overlapping WLANs are present. However, there are usually multiple access points within each WLAN, and there has to be a way to identify those access points and their associated clients. Therefore a BSSID may be included in all wireless packet information. 
     In some aspects, measurement component  140  may be configured to send a request indication (e.g., probe request indication) to a first RAT (e.g., WLAN entity  136 ) for triggering transmission of the management indication. In such aspects, the management indication may comprise a probe response indication or a beacon indication. Additionally, in order to trigger probe responses from any and all desired collocated small cells, measurement component  140  may be configured to send the probe request indication comprising one or both of an SSID or a BSSID. 
     For example, measurement component  140  may be configured to determine that a request indication transmission condition has been met for triggering transmission of the request indication to WLAN entity  136 . In other words, UE  120   y , via measurement component  140 , may determine that communication quality with a small cell (e.g., small cell  110   y ) with which it may be actively connected with has decreased. Specifically, measurement component  140  may be configured to determine that the request indication transmission condition has been met by one or more of determining that a channel quality indicator (CQI) value meets or falls below a CQI threshold value, a bit error rate (BER) value meets or exceeds a BER threshold value, and a CQI backoff value meets or exceeds a CQI backoff threshold value. Additionally, the request transmission condition may be determined based at least in part on radio link failure (RLF) information, outer rate loop control information, or some other mobility related information. 
     Moreover, for example, the telecommunications network system  100  ( FIG. 1 ) may be an LTE network or some other similar wireless wide area network or WWAN. In such LTE aspects, the telecommunications network system  100  may include a number of eNodeBs  110 , each of which may include SON component  130 , user equipment (UEs)  120  including measurement component  140 , and other network entities. An eNodeB  110  for a macro cell may be referred to as a macro eNodeB. An eNodeB  110  for a small cell may be referred to as a small eNodeB. In the example shown in  FIG. 1 , the eNodeBs  110   a ,  110   b  and  110   c  may be macro eNodeBs for the macro cells  102   a ,  102   b  and  102   c , respectively. The eNodeB  110   x ,  110   y  and  110   z  may be a small eNodeB for a small cells  102   x ,  102   y  and  102   z . An eNodeB  110  may provide communication coverage for one or more (e.g., three) cells. 
     It should be understood that each of the eNodeBs may include SON component  130 . In some aspects, the telecommunications network system  100  ( FIG. 1 ) may include one or more relay stations  110   r  and  120   r , that may also be referred to as a relay eNodeB, a relay, etc. The relay station  110   r  may be a station that receives a transmission of data and/or other information from an upstream station (e.g., an eNodeB  110  or a UE  120 ) and sends the received transmission of the data and/or other information to a downstream station (e.g., a UE  120  or an eNodeB  110 ). The relay station  120   r  may be a UE that relays transmissions for other UEs (not shown). In the example shown in  FIG. 1 , the relay station  110   r  may communicate with the eNodeB  110   a  and the UE  120   r  in order to facilitate communication between the eNodeB  110   a  and the UE  120   r.    
     The telecommunications network system  100  ( FIG. 1 ) may be a heterogeneous network that includes eNodeBs  110  of different types, e.g., macro eNodeBs  110   a - c , pico eNodeBs  110   x , femto eNodeBs  110   y - z , relays  110   r , etc. These different types of eNodeBs  110  may have different transmit power levels, different coverage areas, and different impact on interference in the telecommunications network system  100 . For example, macro eNodeBs  110   a - c  may have a high transmit power level (e.g., 20 Watts) whereas pico eNodeBs  110   x , femto eNodeBs  110   y - z  and relays  110   r  may have a lower transmit power level (e.g., 1 Watt). 
     The telecommunications network system  100  may support synchronous or asynchronous operation. For synchronous operation, the eNodeBs  110  may have similar frame timing, and transmissions from different eNodeBs  110  and may be approximately aligned in time. For asynchronous operation, the eNodeBs  110  may have different frame timing, and transmissions from different eNodeBs  110  and may not be aligned in time. The techniques described herein may be used for both synchronous and asynchronous operation. 
     A network controller  124  may be coupled to a set of eNodeBs  110  and provide coordination and control for these eNodeBs  110 . The network controller  124  may communicate with the eNodeBs  110  via a backhaul (not shown). The eNodeBs  110  may also communicate with one another, e.g., directly or indirectly via wireless or wire line backhaul (e.g., X2 interface) (not shown). 
     The UEs  120  (e.g.,  120   x ,  120   y , etc.) may be dispersed throughout the telecommunications network system  100 , and each UE  120  may be stationary or mobile. For example, the UE  120  may be referred to as a terminal, a mobile station, a subscriber unit, a station, etc. In another example, the UE  120  may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a netbook, a smart book, etc. The UE  120  may be able to communicate with macro eNodeBs  110   a - c , pico eNodeBs  110   x , femto eNodeBs  110   y - z , relays  110   r , etc. For example, in  FIG. 1 , a solid line with double arrows may indicate desired transmissions between a UE  120  and a serving eNodeB  110 , which is an eNodeB  110  designated to serve the UE  120  on the downlink and/or uplink. A dashed line with double arrows may indicate interfering transmissions between a UE  120  and an eNodeB  110 . 
     LTE may utilize orthogonal frequency division multiplexing (OFDM) on the downlink and single-carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM may partition the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as tones, bins, etc. Each subcarrier may be modulated with data. In general, modulation symbols may be sent in the frequency domain with OFDM and in the time domain with SC-FDM. The spacing between adjacent subcarriers may be fixed, and the total number of subcarriers (K) may be dependent on the system bandwidth. For example, the spacing of the subcarriers may be 15 kHz and the minimum resource allocation (called a ‘resource block’) may be 12 subcarriers (or 180 kHz). Consequently, the nominal Fast Fourier Transform (FFT) size may be equal to 128, 256, 512, 1024 or 2048 for system bandwidth of 1.25, 2.5, 5, 10 or 20 megahertz (MHz), respectively. The system bandwidth may be partitioned into subbands. For example, a subband may cover 1.08 MHz (i.e., 6 resource blocks), and there may be 1, 2, 4, 8 or 16 subbands for system bandwidth of 1.25, 2.5, 5, 10 or 20 MHz, respectively. 
     Referring to  FIG. 2A , an aspect is illustrated of a communication environment  200  including one or more small cells in communication with one or more UEs for assisting a particular RAT entity of the one or more small cells with a SON configuration. Specifically, communication environment  200  may include first small cell  210 , second small cell  230  and UE  240 . It should be understood that small cells  210  and  230  may be the same as or similar to small cell  110   y  of  FIG. 1 , aspects of which are described herein. Additionally, in some aspects, UE  240  may be the same as or similar to UE  120   y  of  FIG. 1 , aspects of which are described herein. 
     In an aspect, first small cell  210  may receive measurement information from one or both of second small cell  230  and UE  240 . Additionally, first small cell may transmit a request indication (e.g., in the form of a probe request) to one or both of second small cell  230  and UE  240 . In particular, first small cell  210  may include interface component  220 , which may facilitate communication between WLAN entity  136  and WAN entity  138 . That is, interface component  220  may include one or more wired and/or wireless links between WLAN entity  136  and WAN entity  138  configured to enable communication of data such as, but not limited to, measurement information  224  and RAT entity-specific information  226 . Additionally, UE  240  may include WAN entity  242  and WLAN entity  244  configured to communicate with respective entities of one or more small cells, and including an interface component  246  facilitating communication between WAN entity  242  and WLAN entity  244 . 
     In an operational aspect, first small cell  210  may receive measurement information  224  from UE  240 , for example, in response to a transmission of a probe request indication by WLAN entity  136  of first small cell  210  to WLAN entity  244  of UE  240  to trigger UE  240  to perform or otherwise obtain one or more measurements (e.g., RSSI) based on the probe request indication. In other aspects, UE  240  may detect or otherwise determine that a communication quality of the communication environment  200  may have degraded and thus may trigger transmission of a probe request indication to first small cell  210  for triggering transmission of a response indication. 
     In such aspects, first small cell  210  may embed RAT entity-specific information  226  (e.g., related to WAN entity  138 ) within the response indication for transmission to UE  240 . Upon receiving measurement information  224  from UE  240  and/or second small cell  230 , first small cell may be configured to transmit the measurement information to the WAN entity  138  via interface component  220 . Likewise, WAN entity  138  may transmit RAT entity-specific information  226  that may be embedded in a probe indication or response indication to WLAN entity  136  for transmission to UE  240 . 
     Moreover, UE  240  may detect a MAC identifier of a WLAN entity (e.g., WLAN entity  236 ) along with, or in addition to the measurement information  224  (e.g., RSSI). UE  240  may transmit the measurement information  224  along with the MAC identifier of the WLAN entity to first small cell  210 . First small cell  210  may calculate the pathloss between UE  240  and WAN entity  238  of second small cell  230 . The pathloss calculation may be calibrated or otherwise modified to take into account a band difference, a transmit power difference, and an antenna gain difference. Additionally, the pathloss between UE  240  and second small cell  230  may be fed back, along with the MAC identifier of WLAN entity  236 , to the first small cell  210 . The pathloss calibration may be performed at UE  240 , or the UE can transmit measurement information  224  (e.g., RSSI) along with the WLAN entity  236  MAC ID, and a frequency band at which the measurements were performed to the WAN entity  238  such that it may perform the calibration. 
     In further aspects, first small cell  210  and second small cell  230  may listen, either continuously or periodically, to the beacon transmissions of each respective WLAN entity  136 . For example, WLAN entity  136  of first small cell  210  may receive or otherwise determine measurement information  224  (e.g., RSSI) based on receiving a beacon transmission of WLAN entity  236  of second small cell  230 . The measurement information  224  may be transmitted to WAN entity  138  via interface component  220 . 
     Further, WLAN entity  136  and/or WLAN entity  244  may be configured to establish one or both of a connection to a WLAN network and a connection to a Wi-Fi network. In other aspects, WLAN entity  136  may be configured to establish a connection to an unlicensed spectrum network. In such aspects, the measurement information transmitted and/or received according to first management component  132 , second management component, and measurement component  140  may be embedded in one of an unlicensed broadcast indication (e.g., system information block) and/or one or more multi-broadcast single-frequency network frames/indications. Additionally, the second RAT entity is configured to establish one or both of a connection with a WAN and a connection with one or more of a LTE network, a UMTS network, and a CDMA network. 
     In aspects related to the first management component  132  and the second management component  134 , small cell  210  may be configured to include a first RAT identifier associated with, or otherwise used to identify the WLAN entity  136  and a second RAT identifier associated with, or otherwise used to identify the WAN entity  138 . In some aspects, the first RAT identifier may be a cell identifier such as a medium access control (MAC) identifier. In other aspects, the second RAT identifier may a cell identifier such as a physical cell identifier (PCI). For example, to identify or determine the origin of the received information (e.g., measurement information  224 ), small cell  210  having collocated WLAN entity  136  and WAN entity  138  may receive measurement information  224  including identifying information (e.g., cell ID information). 
     That is, in aspects where first small cell  210  may receive measurement information  224  from second small cell, either directly or indirectly via UE  240 , first small cell  210  may decode or determine the identification information to determine the origin of the measurement information  224 . Hence, each small cell in the communication environment  200  may map, or include mapped, in a one-to-one relationship, first RAT identifier (e.g., MAC ID) and second RAT identifier (e.g., PCI) for accurate identification purposes at the neighboring small cell. Likewise, UE  240  may send identification information related to or associated with the measurement information  224  obtained from WLAN entity  236  of second small cell  230  to WLAN entity  136  of first small cell  210 , or vice versa. 
     Referring to  FIG. 2B , an aspect is illustrated of a communication environment  300  including one or more small cells in communication with one or more UEs for assisting a particular RAT entity of the one or more small cells with a SON configuration. Specifically, communication environment  300  may include first small cell  210 , second small cell  230  and UE  240 . It should be understood that small cells  210  and  230  may be the same as or similar to small cell  110   y  of  FIG. 1 , aspects of which are described herein. Additionally, in some aspects, UE  240  may be the same as or similar to UE  120   y  of  FIG. 1 , aspects of which are described herein. 
     In an aspect, small cell  230  may embed RAT entity-specific information (e.g., related to WAN entity  238 ) within a message indication for transmission by WLAN entity  236 , as illustrated by line  302 . In response, in an example of one case, WLAN entity  236  may transmit the message indication including the RAT entity-specific information of WAN entity  238  to small cell  210  and WLAN entity  136 , as illustrated by line  304 . In an example of another case, WLAN entity  236  may transmit the message indication including the RAT entity-specific information of WAN entity  238  to UE  240  and WLAN entity  244 , as illustrated by line  306 , which in turn may transmit the RAT entity-specific information of WAN entity  238  to small cell  210  and WLAN entity  136 , as illustrated by line  310 . In yet another case, for example, as illustrated by line  312 , WLAN entity  236  may transmit the message indication including the RAT entity-specific information of WAN entity  238  to small cell  210  and SON component  130 . In such aspects, the message indication may comprise a probe response indication or a beacon indication including one or more RAT entity-specific information. In further aspects, first small cell  210 , UE  240  and second small cell  230  may listen, either continuously or periodically, to the beacon transmissions of each respective WLAN entity. For example, WLAN entity  136  of first small cell  210  may receive or otherwise determine RAT entity-specific information of WAN entity  238  based on receiving a beacon transmission of WLAN entity  236  of second small cell  230 . This aspect may also operate with other aspects described herein. 
     In the aspect where the RAT entity-specific information of WAN entity  238  is transmitted to UE  240  and WLAN entity  244 , as illustrated by line  306 , UE  240  and/or WLAN entity  244  may attempt to decode the embedded RAT entity-specific information of WAN entity  238 . Once decoded, the RAT entity-specific information of WAN entity  238  may be transmitted to WLAN entity  136 , as illustrated by line  310 , and/or transmitted to SON component  130  of small cell  210 , as illustrated by line  314 . 
     In another aspect, as illustrated by line  308 , UE  240  may embed RAT entity-specific information (e.g., related to WAN entity  242 ) within another message indication for transmission by WLAN entity  244 . As such, in one case, for example, WLAN entity  244  may transmit the message indication including the RAT entity-specific information of WAN entity  242  to small cell  210  and WLAN entity  136 , as illustrated by line  310 . In another case, for example, WLAN entity  244  may transmit the message indication including the RAT entity-specific information of WAN entity  242  to small cell  210  and SON component  130 , as illustrated by line  314 . In yet another case, for example, WLAN entity  244  may transmit the message indication including both the RAT entity-specific information of WAN entity  242  and the RAT entity-specific information of WAN entity  238  to small cell  210  and WLAN entity  136 /SON component  130 , as illustrated by lines  310  and  314 , respectively. These aspects may also operate with other aspects described herein. 
     In one aspect of the communication illustrated by line  320 , where the RAT entity-specific information of WAN entity  238  is transmitted to small cell  210  and WLAN entity  136  from WLAN entity  236 , as illustrated by line  304 , and/or transmitted from WLAN entity  244 , as illustrated by line  310 , WLAN entity  136  may decode the embedded RAT entity-specific information of WAN entity  238 , and transmit the RAT entity-specific information of WAN entity  238  to WAN entity  138 . Further, in another aspect of the communication illustrated by line  320 , where the message indication received by WLAN entity  136  includes the RAT entity-specific information of WAN entity  242 , WLAN entity  136  may decode the embedded RAT entity-specific information of WAN entity  242 , and transmit the RAT entity-specific information of WAN entity  242  to WAN entity  138 . These aspects may also operate with other aspects described herein. 
     In one aspect of the communication illustrated by line  318 , where WLAN entity  136  may transmit the embedded RAT entity-specific information of WAN entity  238  to SON component  130 , as illustrated by line  316 , and/or where WLAN entity  244  may transmit RAT entity-specific information of WAN entity  238  to SON component  130 , as illustrated by line  314 , SON component  130  may decode the embedded RAT entity-specific information of WAN entity  238 , and transmit the RAT entity-specific information of WAN entity  238  to WAN entity  138 . Further, in another aspect of the communication illustrated by line  318 , where the message indication received by SON component  130  includes the RAT entity-specific information of WAN entity  242 , SON component  130  may decode the embedded RAT entity-specific information of WAN entity  242 , and transmit the RAT entity-specific information of WAN entity  242  to WAN entity  138 . These aspects may also operate with other aspects described herein. 
     Referring to  FIGS. 3-6 , the methods are shown and described as a series of acts for purposes of simplicity of explanation. However, it is to be understood and appreciated that the methods (and further methods related thereto) are not limited by the order of acts, as some acts may, in accordance with one or more aspects, occur in different orders and/or concurrently with other acts from that shown and described herein. For example, it is to be appreciated that the methods may alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all illustrated acts may be required to implement a method in accordance with one or more features described herein. 
     Referring to  FIG. 3 , in an operational aspect, a network entity such as small cell  110   y  ( FIG. 1 ) may perform one aspect of a method  500  for managing interference at a second RAT entity (e.g., WAN) based on measurement information received at a first RAT entity (e.g., WLAN) according to the aspects of the first management component  132  ( FIG. 1 ). 
     In an aspect, at block  502 , method  500  may receive, at a first RAT entity, measurement information from a UE for assisting with interference management at a second RAT entity. For example, as described herein, SON component  130  ( FIG. 1 ) may execute first management component  132  ( FIG. 1 ) to receive, at a first RAT entity (e.g., WLAN entity  136 ,  FIG. 1 ), measurement information from a UE  120   y  ( FIG. 1 ) for assisting with interference management at a second RAT entity (e.g., WAN entity  138 ,  FIG. 1 ). In some aspects, the first RAT entity may be collocated with the second RAT entity. Specifically, the measurement information may include a pathloss value determined based at least in part on one or both of a signal strength value and a transmit power value of one or both of the first RAT entity and the second RAT entity. In some aspects, the signal strength value comprises a received signal strength indicator (RSSI) value. As such, WLAN entity  136  and/or UE  120   y  may be configured to determine a pathloss value of the second RAT entity (e.g., WAN entity  138 ) based at least in part on the pathloss value of the first RAT entity (e.g., WLAN entity  136 ) and a correction factor value. In such aspects, the correction factor value may be a function of at least a frequency and/or frequency band of the second RAT entity (e.g., WAN entity  138 ). Additionally, the correction factor may include a transmission power value and an antenna gain value of one or both of WLAN entity  136  and WAN entity  138 . In another aspect, first small cell  210  ( FIG. 2A ) may receive measurement information  224  from UE  240  ( FIG. 2A ), for example, in response to a transmission of a probe request indication by WLAN entity  136  of first small cell  210  to WLAN entity  244  of UE  240  to trigger UE  240  to perform or otherwise obtain one or more measurements (e.g., RSSI) based on the probe request indication. In a further example, UE  240  is may measure pathloss to small cell  230  based on measuring RSSI of a beacon indication or probe response of WLAN entity  236 . Then, UE  240  may transmit the pathloss back to small cell  210 , which may infer the pathloss between UE  240  and WAN entity  238  using the correction factor. The pathloss may then be used for SON and interference management such as power and resource management, along with mobility management. 
     Further, at block  504 , method  500  may configure the second RAT entity based at least in part on the measurement information received by the first RAT entity. For example, as described herein, SON component  130  ( FIG. 1 ) may execute first management component  132  ( FIG. 1 ) to configure the second RAT entity (e.g., WAN entity  138 ,  FIG. 1 ) based at least in part on the measurement information (e.g., pathloss) received by the first RAT entity (e.g., WLAN entity  136 ,  FIG. 1 ). In another aspect, upon receiving measurement information  224  ( FIG. 2A ) from UE  240  ( FIG. 2A ) and/or second small cell  230 , first small cell  210  may be configured to transmit the measurement information to the WAN entity  138  via interface component  220 . 
     Referring to  FIG. 4 , in an operational aspect, a network entity such as small cell  110   y  ( FIG. 1 ) may perform one aspect of a method  600  for managing interference at a second RAT entity (e.g., WAN) based on measurement information received at a first RAT entity (e.g., WLAN) according to the aspects of the second management component  134  ( FIG. 1 ). 
     In an aspect, at block  602 , method  600  may embed, by a first RAT entity, RAT entity-specific information of a second RAT entity in a management indication, wherein the first RAT entity and the second RAT entity are collocated. For example, as described herein, SON component  130  ( FIG. 1 ) may execute second management component  134  ( FIG. 1 ) to embed, by a first RAT entity (e.g., WLAN entity  136 ,  FIG. 1 ), RAT entity-specific information of a second RAT entity (e.g., WAN entity  138 ,  FIG. 1 ) in a management indication. In some aspects, the first RAT entity (e.g., WLAN entity  136 ,  FIG. 1 ) and the second RAT entity (e.g., WAN entity  138 ,  FIG. 1 ) may be collocated. In certain instances, the WLAN entity  136  of small cell  110   y  may be configured to transmit a management indication in the form of a beacon indication to trigger UE  120   y  to measure at least the signal strength (e.g., RSSI) of, or corresponding to, the beacon indication. In such aspects, the transmission of the beacon indication to UE  120   y  may be made periodically. In such aspects, the beacon indication transmitted by the WLAN entity  136  may alternatively be referred to as a beacon frame, which may be a type of management frame, and transmitted periodically to enable WLAN entities and/or UEs to establish and maintain communications in an orderly fashion. For instance, a beacon frame may be a management frame in IEEE 802.11-based WLANs and may include information about the network. In some aspects, a body of the beacon frame may reside between a header and a CRC field and constitutes the other half of the beacon frame. Each beacon frame may carry or include information in the frame body including, but not limited to, a timestamp, a beacon interval, capability information, a SSID, supported rates, a FH Parameter Set, a DS Parameter Set, a CF Parameter Set, an MSS Parameter Set, and a TIM. For example, the beacon indication may include an SSID such as an SSID of another first RAT collocated with another second RAT. In another aspect, first small cell  210  ( FIG. 2A ) may embed RAT entity-specific information  226  (e.g., related to WAN entity  138 ) within the response indication for transmission to UE  240 . 
     Further, at block  604 , method  600  may transmit the management indication to a UE. For instance, as described herein, SON component  130  ( FIG. 1 ) may execute second management component  134  ( FIG. 1 ) to transmit the management indication to a UE (e.g., UE  120 ,  FIG. 1 ). In another aspect, the WLAN entity  136  ( FIG. 2A ) may receive a request indication from one or both of the UE  240  ( FIG. 2A ) and the WLAN entity  236  for triggering transmission of the management indication. For example, WAN entity  138  may transmit RAT entity-specific information  226  that may be embedded in a probe indication or response indication to WLAN entity  136  for transmission to UE  240 . 
     Referring to  FIG. 5 , in an operational aspect, a network entity such as small cell  110   y  ( FIG. 1 ) may perform one aspect of a method  700  for transmitting measurement information from a UE to a small cell for managing interference at a second RAT entity (e.g., WAN entity  138 ,  FIG. 1 ) of the small cell based on measurement information received at a collocated first RAT entity (e.g., WLAN entity  136 ,  FIG. 1 ) according to the aspects of the measurement component  140  ( FIG. 1 ). 
     In an aspect, at block  702 , method  700  may measure a signal strength value corresponding to a management indication received from a first RAT entity for assisting with interference management at a second RAT entity. For instance, as described herein, UE  120   y  ( FIG. 1 ) may execute measurement component  140  ( FIG. 1 ) to measure a signal strength value (e.g., RSSI) corresponding to a management indication (e.g., beacon indication) received from a first RAT entity (e.g., WLAN entity  136 ,  FIG. 1 ) for assisting with interference management at a second RAT entity (e.g., WAN entity  138 ,  FIG. 1 ). In some aspects, the first RAT entity may be collocated with the second RAT entity. For example, measurement component  140  may be configured to determine a pathloss value of the first RAT (e.g., WLAN entity  136 ) based at least in part on one or both of the signal strength value (e.g., RSSI) and a generate power value of one or both of the first RAT and the second RAT. Additionally, upon obtaining and/or determining the pathloss associated with WLAN entity  136 , measurement component  140  may be configured to determine a pathloss value of the second RAT (e.g., WAN entity  138 ) based at least in part on the pathloss value of the first RAT and a correction factor value. In some aspects, the correction factor value may be a function of at least a frequency of the second RAT. In another aspect, UE  240  ( FIG. 2A ) may execute WLAN entity  244  to receive a probe request indication from WLAN entity  136  of first small cell  210 . As a result, UE  240  may execute measurement component  140  to obtain one or more measurements (e.g., RSSI) based on the probe request indication. Moreover, UE  240  may detect a MAC identifier of a WLAN entity (e.g., WLAN entity  236 ) along with, or in addition to, the measurement information  224  (e.g., RSSI). 
     Further, at block  704 , method  700  may transmit measurement information to the first RAT entity for use in configuration of the second RAT entity. For example, as described herein, UE  120   y  ( FIG. 1 ) may execute measurement component  140  ( FIG. 1 ) to transmit measurement information (e.g., pathloss value) to the first RAT entity (e.g., WLAN entity  136 ,  FIG. 1 ) for use in configuration of the second RAT entity (e.g., WAN entity  138 ,  FIG. 1 ). In another aspect, UE  240  ( FIG. 2A ) may execute WLAN entity  244  ( FIG. 2A ) to transmit measurement information (e.g., pathloss value) to the corresponding WLAN entity  136  of the first small cell  210  for us in the configuration of the WAN entity  138 . UE  240  may transmit the measurement information  224  along with the MAC identifier of the WLAN entity to first small cell  210 . First small cell  210  may calculate the pathloss between UE  240  and WAN entity  238  of second small cell  230 . The pathloss calculation may be calibrated or otherwise modified to take into account a band difference, a transmit power difference, and an antenna gain difference. Additionally, the pathloss between UE  240  and second small cell  230  may be fed back, along with the MAC identifier of WLAN entity  236 , to the first small cell  210 . The pathloss calibration may be performed at UE  240 , or the UE can transmit measurement information  224  (e.g., RSSI) along with the WLAN entity  236  MAC ID, and a frequency band at which the measurements were performed to the WAN entity  238  such that it may perform the calibration. 
     Referring to  FIG. 6 , in an operational aspect, a network entity such as small cell  110   y  ( FIG. 1 ) may perform one aspect of a method  800  for managing interference at a second RAT entity (e.g., WAN) based on measurement information received at a first RAT entity (e.g., WLAN) according to the aspects of the first management component  132  ( FIG. 1 ). 
     In an aspect, at block  802 , method  800  may receive, by a first radio access technology (RAT) entity of a first small cell, a first RAT entity identification (ID) corresponding to a first RAT entity of a network device. For example, as described herein, SON component  130  ( FIG. 1 ) may execute first management component  132  ( FIG. 1 ) to receive, at a first RAT entity (e.g., WLAN entity  136 ,  FIG. 1 ), a first RAT entity ID corresponding to a first RAT entity of a network device. In some instances, the first RAT entity ID may correspond to WLAN entity  244  ( FIG. 2A ) of UE  240 . In other instances, the first RAT entity ID may correspond to WLAN entity  236  ( FIG. 2A ) of small cell  230 . 
     In another aspect, at block  804 , method  800  may map the first RAT entity ID to a second RAT entity ID corresponding to a collocated second RAT entity of the network device, wherein measurement information received with the first RAT entity ID at the first RAT entity of the first small cell is used for assisting with interference management at a collocated second RAT entity of the first small cell. For example, as described herein, SON component  130  ( FIG. 1 ) may execute first management component  132  ( FIG. 1 ) to map the first RAT entity ID to a second RAT entity ID corresponding to a collocated second RAT entity of the network device, wherein measurement information  224  ( FIG. 2A ) received with the first RAT entity ID at the first RAT entity (e.g., WLAN  136 ) of the first small cell  210  is used for assisting with interference management at a collocated second RAT entity (e.g., WAN entity  138 ) of the first small cell  210 . In some instances, the measurement information  224  may include the first RAT entity ID, and the measurement information  224  may be received from one or both of a UE (e.g., UE  240 ) and a second small cell (e.g., second small cell  230 ). In other instances, the first RAT entity ID may be mapped to the second RAT entity ID by one or both of the UE  240  and second small cell  230  prior to transmission of the first RAT entity ID to the first small cell  210 . In these instances, UE  240  and/or second small cell  230  may know the mapping configuration of the collocated RAT entities of other devices. As such, two or more RAT entity IDs corresponding to respective two or more collocated RAT entities are mapped in a one-to-one configuration. Further, the first RAT entity ID corresponds to a Wireless Local Access Network (WLAN) Media Access Control (MAC) ID, and the second RAT entity ID corresponds to one or more of a E-UTAN Cell Global Identifier (ECGI), Physical Cell Identifier (PCI), and a Long Term Evolution (LTE) Media Access Control (MAC) ID. 
       FIG. 7  is a block diagram  850  conceptually illustrating an example of a down link frame structure in a telecommunications system in accordance with an aspect of the present disclosure. The transmission timeline for the downlink may be partitioned into units of radio frames. Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be partitioned into 10 sub-frames with indices of 0 through 9. Each sub-frame may include two slots. Each radio frame may thus include 20 slots with indices of 0 through 19. Each slot may include L symbol periods, e.g., 7 symbol periods for a normal cyclic prefix (as shown in  FIG. 7 ) or 14 symbol periods for an extended cyclic prefix (not shown). The 2L symbol periods in each sub-frame may be assigned indices of 0 through 2L−1. The available time frequency resources may be partitioned into resource blocks. Each resource block may cover N subcarriers (e.g., 12 subcarriers) in one slot. 
     In LTE for example, an eNodeB may send a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) for each cell in the coverage area of the eNodeB. The primary synchronization signal (PSS) and secondary synchronization signal (SSS) may be sent in symbol periods  6  and  5 , respectively, in each of sub-frames  0  and  5  of each radio frame with the normal cyclic prefix, as shown in  FIG. 6 . The synchronization signals may be used by UEs for cell detection and acquisition. The eNodeB may send system information in a Physical Broadcast Channel (PBCH) in symbol periods  0  to  3  of slot  1  of sub-frame  0 . 
     The eNodeB may send information in a Physical Control Format Indicator Channel (PCFICH) in only a portion of the first symbol period of each sub-frame, although depicted in the entire first symbol period in  FIG. 6 . The PCFICH may convey the number of symbol periods (M) used for control channels, where M may be equal to 1, 2 or 3 and may change from sub-frame to sub-frame. M may also be equal to 4 for a small system bandwidth, e.g., with less than 10 resource blocks. In the example shown in  FIG. 6 , M=3. The eNodeB may send information in a Physical HARQ Indicator Channel (PHICH) and a Physical Downlink Control Channel (PDCCH) in the first M symbol periods of each sub-frame (M=3). The PHICH may carry information to support hybrid automatic retransmission (HARQ). The PDCCH may carry information on uplink and downlink resource allocation for UEs and power control information for uplink channels. Although not shown in the first symbol period in  FIG. 6 , it may be understood that the PDCCH and PHICH are also included in the first symbol period. 
     Similarly, the PHICH and PDCCH are also both in the second and third symbol periods, although not shown that way in  FIG. 8 . The eNodeB may send information in a Physical Downlink Shared Channel (PDSCH) in the remaining symbol periods of each sub-frame. The PDSCH may carry data for UEs scheduled for data transmission on the downlink. The various signals and channels in LTE are described in 3GPP TS 36.211, entitled “Evolved Universal Terrestrial Radio Access (E-UTRA); Physical Channels and Modulation,” which is publicly available. 
     The eNodeB may send the PSS, SSS and PBCH around the center 1.08 MHz of the system bandwidth used by the eNodeB. The eNodeB may send the PCFICH and PHICH across the entire system bandwidth in each symbol period in which these channels are sent. The eNodeB may send the PDCCH to groups of UEs in certain portions of the system bandwidth. The eNodeB may send the PDSCH to specific UEs in specific portions of the system bandwidth. The eNodeB may send the PSS, SSS, PBCH, PCFICH and PHICH in a broadcast manner to all UEs in the coverage area. The eNodeB may send the PDCCH in a unicast manner to specific UEs in the coverage area. The eNodeB may also send the PDSCH in a unicast manner to specific UEs in the coverage area. 
     A number of resource elements may be available in each symbol period. Each resource element may cover one subcarrier in one symbol period and may be used to send one modulation symbol, which may be a real or complex value. Resource elements not used for a reference signal in each symbol period may be arranged into resource element groups (REGs). Each REG may include four resource elements in one symbol period. The PCFICH may occupy four REGs, which may be spaced approximately equally across frequency, in symbol period  0 . The PHICH may occupy three REGs, which may be spread across frequency, in one or more configurable symbol periods. For example, the three REGs for the PHICH may all belong in symbol period  0  or may be spread in symbol periods  0 ,  1  and  2 . The PDCCH may occupy 9, 18, 32 or 64 REGs, which may be selected from the available REGs, in the first M symbol periods. Only certain combinations of REGs may be allowed for the PDCCH. 
     A UE may know the specific REGs used for the PHICH and the PCFICH. The UE may search different combinations of REGs for the PDCCH. The number of combinations to search is typically less than the number of allowed combinations for the PDCCH. An eNodeB may send the PDCCH to the UE in any of the combinations that the UE will search. 
     A UE may be within the coverage areas of multiple eNodeBs. One of these eNodeBs may be selected to serve the UE. The serving eNodeB may be selected based on various criteria such as received power, path loss, signal-to-noise ratio (SNR), etc. 
       FIG. 8  is a block diagram conceptually illustrating an exemplary eNodeB  910  and an exemplary UE  920  configured in accordance with an aspect of the present disclosure. For example, the base station/eNodeB  910  and the UE  920 , as shown in  FIG. 8 , may be one of the base stations/eNodeBs including SON component  130  and any one of the UEs  120  in  FIG. 1  including measurement component  140 . The base station  910  may be equipped with antennas  934   1-t , and the UE  920  may be equipped with antennas  952   1-r , wherein t and r are integers greater than or equal to one. 
     At the base station  910 , a base station transmit processor  920  may receive data from a base station data source  912  and control information from a base station controller/processor  940 . The control information may be carried on the PBCH, PCFICH, PHICH, PDCCH, etc. The data may be carried on the PDSCH, etc. The base station transmit processor  920  may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The base station transmit processor  920  may also generate reference symbols, e.g., for the PSS, SSS, and cell-specific reference signal (RS). 
     A base station transmit (TX) multiple-input multiple-output (MIMO) processor  930  may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, and/or the reference symbols, if applicable, and may provide output symbol streams to the base station modulators/demodulators (MODs/DEMODs)  932   1-t . Each base station modulator/demodulator  932  may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each base station modulator/demodulator  932  may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. Downlink signals from modulators/demodulators  932   1-t  may be transmitted via the antennas  934   1-t , respectively. 
     At the UE  920 , the UE antennas  952   1-r  may receive the downlink signals from the base station  910  and may provide received signals to the UE modulators/demodulators (MODs/DEMODs)  954   1-r , respectively. Each UE modulator/demodulator  954  may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each UE modulator/demodulator  954  may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A UE MIMO detector  956  may obtain received symbols from all the UE modulators/demodulators  954   1-r , and perform MIMO detection on the received symbols if applicable, and provide detected symbols. A UE reception processor  958  may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE  920  to a UE data sink  960 , and provide decoded control information to a UE controller/processor  980 . 
     On the uplink, at the UE  920 , a UE transmit processor  964  may receive and process data (e.g., for the PUSCH) from a UE data source  962  and control information (e.g., for the PUCCH) from the UE controller/processor  980 . The UE transmit processor  964  may also generate reference symbols for a reference signal. The symbols from the UE transmit processor  964  may be precoded by a UE TX MIMO processor  966  if applicable, further processed by the UE modulator/demodulators  954   1-r  (e.g., for SC-FDM, etc.), and transmitted to the base station  910 . At the base station  910 , the uplink signals from the UE  920  may be received by the base station antennas  934 , processed by the base station modulators/demodulators  932 , detected by a base station MIMO detector  936  if applicable, and further processed by a base station reception processor  938  to obtain decoded data and control information sent by the UE  920 . The base station reception processor  938  may provide the decoded data to a base station data sink  946  and the decoded control information to the base station controller/processor  940 . 
     The base station controller/processor  940  and the UE controller/processor  380  may direct the operation at the base station  910  and the UE  920 , respectively. The base station controller/processor  940  and/or other processors and modules at the base station  910  may perform or direct, e.g., the execution of various processes for the techniques described herein. The UE controller/processor  980  and/or other processors and modules at the UE  920  may also perform or direct, e.g., the execution of the functional blocks illustrated in  FIGS. 6 and 7  and/or other processes for the techniques described herein. The base station memory  342  and the UE memory  982  may store data and program codes for the base station  910  and the UE  920 , respectively. A scheduler  944  may schedule UEs  920  for data transmission on the downlink and/or uplink. 
     In one configuration, the base station  910  may include means for generating a compact Downlink Control Information (DCI) for at least one of uplink (UL) or downlink (DL) transmissions, wherein the compact DCI comprises a reduced number of bits when compared to certain standard DCI formats; and means for transmitting the DCI. In one aspect, the aforementioned means may be the base station controller/processor  940 , the base station memory  942 , the base station transmit processor  920 , the base station modulators/demodulators  932 , and the base station antennas  934  configured to perform the functions recited by the aforementioned means. In another aspect, the aforementioned means may be a module or any apparatus configured to perform the functions recited by the aforementioned means. 
     In one configuration, the UE  920  may include means for receiving compact Downlink Control Information (DCI) for at least one of uplink (UL) or downlink (DL) transmissions, wherein the DCI comprises a reduced number of bits of a standard DCI format; and means for processing the DCI. In one aspect, the aforementioned means may be the UE controller/processor  980 , the UE memory  982 , the UE reception processor  958 , the UE MIMO detector  956 , the UE modulators/demodulators  954 , and the UE antennas  952  configured to perform the functions recited by the aforementioned means. In another aspect, the aforementioned means may be a module or any apparatus configured to perform the functions recited by the aforementioned means. 
       FIG. 9  illustrates an example communication system  1000  where one or more small cells are deployed within a network environment. Specifically, the system  1000  includes multiple small cells  1010  (e.g., small cells or HNB  1010 A and  1010 B) and installed in a relatively small scale network environment (e.g., in one or more user residences  1030 ), wherein the small cells  1010  may be the same as or similar to small cell  110   y  ( FIG. 1 ) including SON component  130  ( FIG. 1 ). Each small cell  1010  may be coupled to a wireless local area network and/or a wide area network  1040  (e.g., the Internet) and a mobile operator core network  1050  via a routing device, a cable modem, a wireless link, or other connectivity means (not shown). 
     As described herein, each small cell  1010  may be configured to serve associated access terminals  1020 , each of which may include measurement component  140  ( FIG. 1 ) (e.g., access terminal  1020 A) and, optionally, alien access terminals  1020  (e.g., access terminal  1020 B), both of which may be the same as or similar to UEs  120  ( FIG. 1 ). In other words, access to small cells  1010  may be restricted whereby a given access terminal  1020  may be served by a set of designated (e.g., home) small cell(s)  1010  but may or may not be served by any non-designated small cells  1010  (e.g., a neighboring small cell). 
     UEs (e.g., LTE-Advanced enabled UEs) may use spectrum of up to 20 MHz bandwidths allocated in a carrier aggregation of up to a total of 100 MHz (5 component carriers) used for transmission and reception. For the LTE-Advanced enabled wireless communication systems, two types of carrier aggregation (CA) methods have been proposed, continuous CA and non-continuous CA, which are illustrated in  FIGS. 9 and 10 , respectively. Continuous CA occurs when multiple available component carriers are adjacent to each other (as illustrated in  FIG. 9 ). On the other hand, non-continuous CA occurs when multiple non-adjacent available component carriers are separated along the frequency band (as illustrated in  FIG. 10 ). It should be understood that any one or more small cells (e.g., network entities), including small cell  110   y , illustrated in  FIG. 1  may communicate or facilitate communication with one or more UEs (e.g., UE  120   y ,  FIG. 1 ) according to the aspects set forth with regard to  FIGS. 10 and 11 . 
     Both continuous CA  1070  ( FIG. 10 ) and non-continuous CA  1080  ( FIG. 11 ) may aggregate multiple component carriers to serve a single unit of LTE-Advanced UEs. In various examples, the UE operating in a multicarrier system (also referred to as carrier aggregation) is configured to aggregate certain functions of multiple carriers, such as control and feedback functions, on the same carrier, which may be referred to as a “primary carrier.” The remaining carriers that depend on the primary carrier for support may be referred to as “associated secondary carriers.” For example, the UE may aggregate control functions such as those provided by the optional dedicated channel (DCH), the nonscheduled grants, a physical uplink control channel (PUCCH), and/or a physical downlink control channel (PDCCH). 
     LTE-A standardization may require carriers to be backward-compatible, to enable a smooth transition to new releases. However, backward-compatibility may require the carriers to continuously transmit common reference signals (CRS), also may be referred to as (cell-specific reference signals) in every subframe across the bandwidth. Most cell site energy consumption may be caused by the power amplifier since the cell remains on even when only limited control signalling is being transmitted, causing the amplifier to continuously consume energy. CRS were introduced in release 8 of LTE standard and may be referred to as LTE&#39;s most basic downlink reference signal. 
     For example, CRS may be transmitted in every resource block in the frequency domain and in every downlink subframe. CRS in a cell can be for one, two, or four corresponding antenna ports. CRS may be used by remote terminals to estimate channels for coherent demodulation. A new carrier type may allow temporarily switching off of cells by removing transmission of CRS in four out of five subframes. This reduces power consumed by the power amplifier. It also may reduce the overhead and interference from CRS since the CRS won&#39;t be continuously transmitted in every subframe across the bandwidth. In addition, the new carrier type may allow the downlink control channels to be operated using UE-specific demodulation reference symbols. The new carrier type might be operated as a kind of extension carrier along with another LTE/LTE-A carrier or alternatively as standalone non-backward compatible carrier.

Module  1302  may correspond to, for example, a processing system as discussed herein. Further, in an aspect, access terminal apparatus  1300  includes a module  1304  for transmitting measurement information to the first RAT entity for use in configuration of the second RAT entity. Module  1304  may correspond to, for example, a processing system as discussed herein. 
       FIG. 15  illustrates an example access terminal apparatus  1400  represented as a series of interrelated functional modules), wherein the access terminal apparatus  1400  may be the same as or similar to UE  120   y  ( FIG. 1 ) including SON component  130  ( FIG. 1 ).

Further, in an aspect, access terminal apparatus  1400  includes a module for mapping the first RAT entity ID to a second RAT entity ID corresponding to a collocated second RAT entity of the network device, wherein measurement information received with the first RAT entity ID at the first RAT entity of the first small cell is used for assisting with interference management at a collocated second RAT entity of the first small cell. Module  1404  may correspond to, for example, a processing system as discussed herein. 
     The functionality of the modules of  FIGS. 12-15  may be implemented in various ways consistent with the teachings herein. In some aspects, for example, the functionality of these modules may be implemented as one or more electrical components. In some aspects, for example, the functionality of these blocks may be implemented as a processing system including one or more processor components. In some aspects, the functionality of these modules may be implemented using, for example, at least a portion of one or more integrated circuits (e.g., an ASIC). As discussed herein, an integrated circuit may include a processor, software, other related components, or some combination thereof. Thus, the functionality of different modules may be implemented, for example, as different subsets of an integrated circuit, as different subsets of a set of software modules, or a combination thereof. Also, it should be appreciated that a given subset (e.g., of an integrated circuit and/or of a set of software modules) may provide at least a portion of the functionality for more than one module. 
     In addition, the components and functions represented by  FIGS. 12-15  as well as other components and functions described herein, may be implemented using any suitable means. Such means also may be implemented, at least in part, using corresponding structure as taught herein. For example, the components described above in conjunction with the “module” components of  FIGS. 12-15  also may correspond to similarly designated “means for” functionality. Thus, in some aspects, one or more of such means may be implemented using one or more of processor components, integrated circuits, or other suitable structure as taught herein. 
     Those of skill in the art would understand that information and signals may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof. 
     Further, those of skill would further appreciate that the various illustrative logical blocks, modules, circuits, and algorithm steps described in connection with the disclosure herein may be implemented as electronic hardware, computer software, or combinations of both. To clearly illustrate this interchangeability of hardware and software, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present disclosure. 
     The various illustrative logical blocks, modules, and circuits described in connection with the disclosure herein may be implemented or performed with a general-purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration. 
     The steps of a method or algorithm described in connection with the disclosure herein may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module may reside in RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. An exemplary storage medium is coupled to the processor such that the processor can read information from, and write information to, the storage medium. In the alternative, the storage medium may be integral to the processor. The processor and the storage medium may reside in an ASIC. The ASIC may reside in a user terminal. In the alternative, the processor and the storage medium may reside as discrete components in a user terminal. 
     In one or more exemplary designs, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Computer-readable media includes both computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another. A storage media may be any available media that can be accessed by a general purpose or special purpose computer. By way of example, and not limitation, such computer-readable media can comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to carry or store desired program code means in the form of instructions or data structures and that can be accessed by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. 
     Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a web site, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of medium. Disk and disc, as used herein, includes compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray disc where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above should also be included within the scope of computer-readable media. 
     The previous description of the disclosure is provided to enable any person skilled in the art to make or use the disclosure. Various modifications to the disclosure will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other variations without departing from the spirit or scope of the disclosure. Thus, the disclosure is not intended to be limited to the examples and designs described herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
