     2. Background 
     Wireless communication systems are widely deployed to provide various types of communication content such as, for example, voice, data, and so on. Typical wireless communication systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, . . . ). Examples of such multiple-access systems may include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, and the like. Additionally, the systems can conform to specifications such as third generation partnership project (3GPP), 3GPP long term evolution (LTE), ultra mobile broadband (UMB), and/or multi-carrier wireless specifications such as evolution data optimized (EV-DO), one or more revisions thereof, etc. 
     Generally, wireless multiple-access communication systems may simultaneously support communication for multiple mobile devices. Each mobile device may communicate with one or more base stations via transmissions on forward and reverse links. The forward link (or downlink) refers to the communication link from base stations to mobile devices, and the reverse link (or uplink) refers to the communication link from mobile devices to base stations. Further, communications between mobile devices and base stations may be established via single-input single-output (SISO) systems, multiple-input single-output (MISO) systems, multiple-input multiple-output (MIMO) systems, and so forth. In addition, mobile devices can communicate with other mobile devices (and/or base stations with other base stations) in peer-to-peer wireless network configurations.

     DETAILED DESCRIPTION 
     Various aspects are now described with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that such aspect(s) may be practiced without these specific details. 
     As used in this application, the terms “component,” “module,” “system” and the like are intended to include a computer-related entity, such as but not limited to hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a computing device and the computing device can be a component. One or more components can reside within a process and/or thread of execution and a component may be localized on one computer and/or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. The components may communicate by way of local and/or remote processes such as in accordance with a signal having one or more data packets, such as data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems by way of the signal. 
     Furthermore, various aspects are described herein in connection with a terminal, which can be a wired terminal or a wireless terminal. A terminal can also be called a system, device, subscriber unit, subscriber station, mobile station, mobile, mobile device, remote station, remote terminal, access terminal, user terminal, terminal, communication device, user agent, user device, or user equipment (UE). A wireless terminal may be a cellular telephone, a satellite phone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device having wireless connection capability, a computing device, or other processing devices connected to a wireless modem. Moreover, various aspects are described herein in connection with a base station. A base station may be utilized for communicating with wireless terminal(s) and may also be referred to as an access point, a Node B, or some other terminology. 
     Moreover, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from the context, the phrase “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, the phrase “X employs A or B” is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from the context to be directed to a singular form. 
     The techniques described herein may be used for various wireless communication systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other systems. The terms “system” and “network” are often used interchangeably. A CDMA system may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband-CDMA (W-CDMA) and other variants of CDMA. Further, cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA system may implement a radio technology such as Global System for Mobile Communications (GSM). An OFDMA system 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-OFDM, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunication System (UMTS). 3GPP Long Term Evolution (LTE) is a release of UMTS that uses E-UTRA, which employs OFDMA on the downlink and SC-FDMA on the uplink. UTRA, E-UTRA, UMTS, LTE and GSM are described in documents from an organization named “3rd Generation Partnership Project” (3GPP). Additionally, cdma2000 and UMB are described in documents from an organization named “3rd Generation Partnership Project 2” (3GPP2). Further, such wireless communication systems may additionally include peer-to-peer (e.g., mobile-to-mobile) ad hoc network systems often using unpaired unlicensed spectrums, 802.xx wireless LAN, BLUETOOTH and any other short- or long-range, wireless communication techniques. 
     Various aspects or features will be presented in terms of systems that may include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. A combination of these approaches may also be used. 
     Referring now to  FIG. 1 , a wireless communication system  100  is illustrated in accordance with various embodiments presented herein. System  100  comprises a base station  102  that can include multiple antenna groups. For example, one antenna group can include antennas  104  and  106 , another group can comprise antennas  108  and  110 , and an additional group can include antennas  112  and  114 . Two antennas are illustrated for each antenna group; however, more or fewer antennas can be utilized for each group. Base station  102  can additionally include a transmitter chain and a receiver chain, each of which can in turn comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art. 
     Base station  102  can communicate with one or more mobile devices such as mobile device  116  and mobile device  122 ; however, it is to be appreciated that base station  102  can communicate with substantially any number of mobile devices similar to mobile devices  116  and  122 . Mobile devices  116  and  122  can be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable device for communicating over wireless communication system  100 . As depicted, mobile device  116  is in communication with antennas  112  and  114 , where antennas  112  and  114  transmit information to mobile device  116  over a forward link  118  and receive information from mobile device  116  over a reverse link  120 . Moreover, mobile device  122  is in communication with antennas  104  and  106 , where antennas  104  and  106  transmit information to mobile device  122  over a forward link  124  and receive information from mobile device  122  over a reverse link  126 . In a frequency division duplex (FDD) system, forward link  118  can utilize a different frequency band than that used by reverse link  120 , and forward link  124  can employ a different frequency band than that employed by reverse link  126 , for example. Further, in a time division duplex (TDD) system, forward link  118  and reverse link  120  can utilize a common frequency band and forward link  124  and reverse link  126  can utilize a common frequency band. 
     Each group of antennas and/or the area in which they are designated to communicate can be referred to as a sector of base station  102 . For example, antenna groups can be designed to communicate to mobile devices in a sector of the areas covered by base station  102 . In communication over forward links  118  and  124 , the transmitting antennas of base station  102  can utilize beamforming to improve signal-to-noise ratio of forward links  118  and  124  for mobile devices  116  and  122 . Also, while base station  102  utilizes beamforming to transmit to mobile devices  116  and  122  scattered randomly through an associated coverage, mobile devices in neighboring cells can be subject to less interference as compared to a base station transmitting through a single antenna to all its mobile devices. 
     Base station  102  (and/or each sector of base station  102 ) can employ one or more multiple access technologies (e.g., CDMA, TDMA, FDMA, OFDMA, . . . ). For instance, base station  102  can utilize a particular technology for communicating with mobile devices (e.g., mobile devices  116  and  122 ) upon a corresponding bandwidth. Moreover, if more than one technology is employed by base station  102 , each technology can be associated with a respective bandwidth. The technologies described herein can include following: Global System for Mobile (GSM), General Packet Radio Service (GPRS), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Wideband Code Division Multiple Access (W-CDMA), cdmaOne (IS-95), CDMA2000, Evolution-Data Optimized (EV-DO), Ultra Mobile Broadband (UMB), Worldwide Interoperability for Microwave Access (WiMAX), MediaFLO, Digital Multimedia Broadcasting (DMB), Digital Video Broadcasting-Handheld (DVB-H), etc. It is to be appreciated that the aforementioned listing of technologies is provided as an example and the claimed subject matter is not so limited; rather, substantially any wireless communication technology is intended to fall within the scope of the hereto appended claims. 
     Base station  102  can employ a first bandwidth with a first technology. Moreover, base station  102  can transmit a pilot corresponding to the first technology on a second bandwidth. According to an illustration, the second bandwidth can be leveraged by base station  102  and/or any disparate base station (not shown) for communication that utilizes any second technology. Moreover, the pilot can indicate the presence of the first technology (e.g., to a mobile device communicating via the second technology). For example, the pilot can use bit(s) to carry information about the presence of the first technology. Additionally, information such as a SectorID of the sector utilizing the first technology, a CarrierIndex indicating the first frequency bandwidth, and the like can be included in the pilot. 
     According to another example, the pilot can be a beacon (and/or a sequence of beacons). A beacon can be an OFDM symbol where a large fraction of the power is transmitted on one subcarrier or a few subcarriers (e.g., small number of subcarriers). Thus, the beacon provides a strong peak that can be observed by mobile devices, while interfering with data on a narrow portion of bandwidth (e.g., the remainder of the bandwidth can be unaffected by the beacon). Following this example, a first sector can communicate via CDMA on a first bandwidth and a second sector can communicate via OFDM on a second bandwidth. Accordingly, the first sector can signify the availability of CDMA on the first bandwidth (e.g., to mobile device(s) operating utilizing OFDM on the second bandwidth) by transmitting an OFDM beacon (or a sequence of OFDM beacons) upon the second bandwidth. 
     The subject innovation can, in general, enable efficient cell selection and reselection in deployments that include a home node base station (home nodeB, HNB, etc.). The claimed subject matter can provide for techniques for legacy user equipment (UE) and/or user equipment (UE) to incorporate the capability to leverage a home nodeB in addition to existing nodeBs. Thus, modifications are provided to cell selection and reselection in order to implement efficient home nodeB search, selection, and reselection. Additionally, by incorporating such modifications, the subject innovation can mitigate the impact on standby time of a UE (e.g., legacy UE, etc.) as well as a UE with no subscription to a home nodeB. 
     The claimed subject matter can employ at least one of the following modifications in order to optimize cell search, selection, and/or reselection: a manual search for a home nodeB; system information block (SIB) configuration for UE, wherein SIB on a macro network (that includes the nodeB) and SIB on a home nodeB can facilitate discovery for the UE; a hierarchical cell structure for prioritization of a home nodeB over a nodeB; separate public land mobile network identification (PLMN ID) for home nodeBs and nodeBs, wherein the PLMN ID can be utilized to prioritize a home nodeB over a macro network (that includes the nodeB); location area code assignment (LAC) for home nodeBs and nodeBs, wherein the LAC assignment can distinguish a home nodeB from a nodeB; UE based learning to leverage home nodeBs that the UE had previously connected in order to efficient connect to such previous home nodeBs; or broadcast of scrambling codes that can be utilized to distinguish a home nodeB from a nodeB.

     Base station  302  can include a receiver module  312  that can receive a communication from the UE  304  that identifies a detected home nodeB. In other words, the UE can detect a home nodeB and the receiver module  312  can receive information related to such detected home nodeB (e.g., home nodeB parameters, etc.). 
     Base station  302  can include an organizer module  314  that can hierarchically structure or arrange the priority of connectivity in which a detected home nodeB can be preferred over a nodeB or macro nodeB. In general, the organizer module  314  can broadcast home nodeB parameters and macro nodeB parameters, wherein the home nodeB parameters can be distinguishable and prioritized over the macro nodeB parameters. 
     Additionally, the base station  302  can include a transmitter module  316  that can broadcast the home nodeB parameters and the macro nodeB parameters, wherein the home nodeB parameters can be communicated to disparate UEs that have not discovered or are unaware of the home nodeBs within proximity or range. The transmitter  316  can broadcast or communicate portions of data related to the parameters for home nodeBs or the macro nodeBs, wherein the portion of data is at least one of a SIB for a home nodeB, a SIB for a nodeB, a PLMN ID for a home nodeB, a PLMN ID for a nodeB, a LAC for a home nodeB, or a LAC for a nodeB. 
     In general, the subject innovation can modify cell search, cell selection, and cell reselection techniques in connection with home nodeBs. The innovation can mitigate the impact on standby time of a legacy UE as well as UEs with no subscription to any home nodeB. A manual search can be implemented in order to allow a UE to identify a home nodeB within a pre-defined proximity or range. In addition, the subject innovation can modify neighbor set configuration, wherein SIB type can be configured on a macro network and a home nodeB in order to enable the UE to prioritize the home nodeB over the macro network (and including nodeBs). For example, SIB3 and SIB11 on the macro nodeB as well as the home nodeB can be configured to assist the UE to discover the home nodeB. Once discovered, the UE can prioritize the home nodeB over the macrocell. 
     Moreover, the claimed subject matter can implement a hierarchy of cells, wherein the hierarchy of cells can prioritize a home nodeB over a macro nodeB. Both mobility criterion and penalty timer can control home nodeB search and cell reselection. Additionally, the subject innovation can prioritize a home nodeB over a nodeB or macro nodeB by leveraging PLMN ID. Separate PLMN ID allocation for macro network and home nodeB networks can prioritize a home nodeB over a macro nodeB. Further, equivalent PLMN IDs can be updated dynamically in order to adjust searching for the home nodeB. Moreover, LAC allocation can be leveraged in order to allow the UE to distinguish an authorized home nodeB from an unauthorized home nodeB. 
     The subject innovation can further provide UE based learning, wherein the UE can prioritize a search for recently utilized PLMN to reduce latency and current drain for system selection. The UE can store, record, maintain a list, or remember a set of home nodeBs that it has connected (e.g., recently used). Further after a first discovery, the UE can leverage such set of home nodeBs to maintain or record relevant information for efficient home nodeB discovery at a later time. Additionally, the subject innovation can mitigate the impact on UEs that are not authorized on any home nodeB. A scrambling code allocated to home nodeBs can be utilized to distinguish those assigned to macro nodeBs in the neighbor list and broadcast a new SIB or an existing SIB. The LAC allocation can further be utilized to allow the UE to distinguish an authorized home nodeB from an unauthorized home nodeB. Similarly, for the hierarchical cells approach, a distinct high priority can be reserved for the home nodeB. With such distinction, a UE can be prevented from implementing home nodeB discovery and may not search for a home nodeB. 
     A study on legacy Home NodeB (HNB) support for UTRA concluded that the presently available mechanisms for legacy UE mobility for UTRA HNB deployments appear not to be optimal and hence may require modification for efficient support of cell reselection in the presence of HNBs or Femto cells. Thus, it would be advantageous to identify the interaction between the possible HNB deployment scenarios and provide enhancements required for cell selection/reselection in the presence of HNBs. 
     There can be various deployment embodiments. HNB deployment embodiments may be distinguished by many categories, such as, for example, association model (closed/open subscriber group), relationship between the HNB spectrum and the macro network spectrum, network architecture, etc. From the HNB cell reselection perspective the following two categories can be related: Association model: The supported association models include open association (e.g., open access), closed subscriber group (CSG e.g., restricted association). Open association allows any subscriber to camp onto any HNB and to access any CS and PS services while camped on that HNB. CSG limits the subscriber to camp only onto authorized HNBs. Thus, the subscriber cannot camp on unauthorized HNBs and cannot access CS and PS services using any unauthorized HNB. Relationship between HNB spectrum and macro network spectrum: HNBs may be deployed on one or more carriers. Furthermore, the HNB deployment may either share one or more carriers with macro network or have its own dedicated carriers separate from those of macro network. 
     With that categorization, the HNB deployment embodiments can be the following: 1) Open association—shared carrier between macrocell and HNB; 2) Open association—dedicated carrier to HNBs; 3) CSG—shared carrier between macrocell and HNB; and 4) CSG—dedicated carrier to HNBs. 
     The subject innovation can develop HNB cell selection/reselection solutions applicable to the above deployment embodiments. For example, HNBs provide several motivations for operators, and these motivations can stipulate requirements on HNB cell selection/reselection. As an example, an operator may consider an HNB deployment to improve overall coverage by supplementing macro network coverage. In such a scenario, the subscriber chooses the best coverage available which can be provided by either the HNB or the macro network. Thus, the operator may not perceive a requirement to prioritize the selection of HNB over that of the macro network. Alternatively, an operator may introduce special billing plans by distinguishing services offered by HNB. In such a scenario, the subscriber will prioritize the selection of HNB over that of the macro network. The opportunity to offload traffic from macro network to HNB can also motivate such a prioritization. The subject innovation can further support the prioritization of HNBs over the macro network when sufficient quality HNB coverage is available. 
     Various alternate approaches toward HNB search are further summarized below: 1) Manual search: Subscriber may always rely on manual search to discover nearby HNB. 2) Neighbor set configuration: Both SIB3 and SIB11 on macro NB as well as HNB are configured to help UE discover HNB. Upon discovery, UE may prioritize HNB over macrocell. 3) Hierarchical cells: Hierarchical cells help prioritize the HNB over macro NB. Both mobility criterion and penalty timer can control HNB search and cell reselection. 4) PLMN ID allocation: Separate PLMN ID allocation for macro network and HNB network can help prioritize HNB over macro network. Further, the equivalent PLMNs can be updated dynamically for adjusting the search for the HNB. 5) Location Area Code (LAC) allocation. LAC assignment may be used to allow a UE to distinguish an authorized HNB from a nearby unauthorized HNB. 6) UE based learning: Current UEs prioritize search for recently used PLMN to reduce latency and current drain for system selection. With the introduction of HNBs, this procedure can be extended so that the UE remembers a set of HNBs that it has recently used. Furthermore, after the first discovery, UE can remember the relevant information for efficient HNB discovery later. 
     In Table 1 below, matching of the above approaches to the deployment embodiments and the prioritization requirement discussed above is further summarized.

     As indicated in the table above, neighbor set configuration and hierarchical cells approaches affect all UEs in the coverage of the macro NBs that support these features. While in macro coverage, the UEs then search actively for the HNBs. For the CSG deployment, frequent discovery of the unauthorized HNBs can result in frequent registration attempts and degradation in standby time. In order to mitigate this impact on UEs that are not authorized on any HNB, scrambling codes allocated to HNBs can be distinguished from those assigned to macro NBs in the neighbour list and broadcast as a new SIB or an extension of an existing SIB. LAC allocation can be used to allow a UE to distinguish an authorized HNB from a nearby unauthorized HNB. Similarly, for the hierarchical cells approach one can reserve a distinct high priority for the HNBs. With that distinction, UEs not interested in HNB discovery will not search for HNBs. 
     To support CSG deployments, the subject innovation can mitigate impact on UEs with no HNB subscription (macro UEs) by distinguishing the HNB parameters from the macro NB parameters broadcasted in macro network. Furthermore, neighbor set configuration, hierarchical cells, as well as PLMN ID allocation approaches suit the open association deployment well. For the CSG deployment, these approaches can be complemented by relying on UE based learning. By leveraging local stored information (local database), UE can avoid fruitless registration attempts with unauthorized HNBs and search efficiently for authorized HNBs. Moreover, by implementing UE based learning, the subject innovation can improve HNB discovery. 
     The subject innovation can be utilized for home nodeB selection and reselection to the above mentioned deployment scenarios. Moreover, home nodeBs can be prioritized over a macro network or nodeB when sufficient quality home nodeB coverage is available. Additionally, to support CSG deployments and mitigate impact on UEs with no home nodeB subscription, a distinction between the home nodeB parameters from the macro nodeB parameters can be broadcasted in the macro network.

Further, base station  302  can include a processor that may be utilized in connection with executing instructions (e.g., instructions retained within memory, instructions obtained from a disparate source, . . . ).

       FIG. 8  shows an example wireless communication system  800 . The wireless communication system  800  depicts one base station  810  and one mobile device  850  for sake of brevity. However, it is to be appreciated that system  800  can include more than one base station and/or more than one mobile device, wherein additional base stations and/or mobile devices can be substantially similar or different from example base station  810  and mobile device  850  described below. In addition, it is to be appreciated that base station  810  and/or mobile device  850  can employ the systems ( FIGS. 1-3 and 6-7 ) and/or methods ( FIGS. 4-5 ) described herein to facilitate wireless communication there between. 
     At base station  810 , traffic data for a number of data streams is provided from a data source  812  to a transmit (TX) data processor  814 . According to an example, each data stream can be transmitted over a respective antenna. TX data processor  814  formats, codes, and interleaves the traffic data stream based on a particular coding scheme selected for that data stream to provide coded data. 
     The coded data for each data stream can be multiplexed with pilot data using orthogonal frequency division multiplexing (OFDM) techniques. Additionally or alternatively, the pilot symbols can be frequency division multiplexed (FDM), time division multiplexed (TDM), or code division multiplexed (CDM). The pilot data is typically a known data pattern that is processed in a known manner and can be used at mobile device  850  to estimate channel response. The multiplexed pilot and coded data for each data stream can be modulated (e.g., symbol mapped) based on a particular modulation scheme (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM), etc.) selected for that data stream to provide modulation symbols. The data rate, coding, and modulation for each data stream can be determined by instructions performed or provided by processor  830 . 
     The modulation symbols for the data streams can be provided to a TX MIMO processor  820 , which can further process the modulation symbols (e.g., for OFDM). TX MIMO processor  820  then provides N T  modulation symbol streams to N T  transmitters (TMTR)  822   a  through  822   t . In various embodiments, TX MIMO processor  820  applies beamforming weights to the symbols of the data streams and to the antenna from which the symbol is being transmitted. 
     Each transmitter  822  receives and processes a respective symbol stream to provide one or more analog signals, and further conditions (e.g., amplifies, filters, and upconverts) the analog signals to provide a modulated signal suitable for transmission over the MIMO channel. Further, N T  modulated signals from transmitters  822   a  through  822   t  are transmitted from N T  antennas  824   a  through  824   t , respectively. 
     At mobile device  850 , the transmitted modulated signals are received by N R  antennas  852   a  through  852   r  and the received signal from each antenna  852  is provided to a respective receiver (RCVR)  854   a  through  854   r . Each receiver  854  conditions (e.g., filters, amplifies, and downconverts) a respective signal, digitizes the conditioned signal to provide samples, and further processes the samples to provide a corresponding “received” symbol stream. 
     An RX data processor  860  can receive and process the N R  received symbol streams from N R  receivers  854  based on a particular receiver processing technique to provide N T  “detected” symbol streams. RX data processor  860  can demodulate, deinter-leave, and decode each detected symbol stream to recover the traffic data for the data stream. The processing by RX data processor  860  is complementary to that performed by TX MIMO processor  820  and TX data processor  814  at base station  810 . 
     A processor  870  can periodically determine which precoding matrix to utilize as discussed above. Further, processor  870  can formulate a reverse link message comprising a matrix index portion and a rank value portion. 
     The reverse link message can comprise various types of information regarding the communication link and/or the received data stream. The reverse link message can be processed by a TX data processor  838 , which also receives traffic data for a number of data streams from a data source  836 , modulated by a modulator  880 , conditioned by transmitters  854   a  through  854   r , and transmitted back to base station  810 . 
     At base station  810 , the modulated signals from mobile device  850  are received by antennas  824 , conditioned by receivers  822 , demodulated by a demodulator  840 , and processed by a RX data processor  842  to extract the reverse link message transmitted by mobile device  850 . Further, processor  830  can process the extracted message to determine which precoding matrix to use for determining the beamforming weights. 
     Processors  830  and  870  can direct (e.g., control, coordinate, manage, etc.) operation at base station  810  and mobile device  850 , respectively. Respective processors  830  and  870  can be associated with memory  832  and  872  that store program codes and data. Processors  830  and  870  can also perform computations to derive frequency and impulse response estimates for the uplink and downlink, respectively.
