     DETAILED DESCRIPTION 
     Various wireless cellular communication systems have been implemented, including a 3rd Generation Partnership Project (3GPP) Universal Mobile Telecommunications System, a 3GPP Long-Term Evolution (LTE) system, and a 3GPP LTE-Advanced (LTE-A) system Next-generation wireless cellular communication systems that are being developed, such as a fifth generation (5G) wireless system/5G mobile networks system, may improve access to information and sharing of data by various users and applications. 
     5G systems may provide improved user experiences with faster, better, simpler, richer, and more seamless wireless connectivity for content and services. In general, 5G systems may be based upon LTE-A systems with additional new Radio Access Technologies (RATs). 5G systems may provide unified networks and systems to support various services and applications that may have different and sometimes conflicting performance requirements. 
     5G systems may support higher-speed user experiences by supporting higher bandwidths. In turn, higher bandwidths may be achieved at least in part by supporting higher carrier frequencies, such as by supporting centimeter-wave (cmWave) or millimeter-wave (mmWave) frequencies. However, mid-band frequencies (e.g., carrier frequencies between 6 gigahertz (GHz) and 30 GHz, or between 50 mm wavelength and 10 mm wavelength) and high-band frequencies (e.g., carrier frequencies of 30 GHz and above) may be subject to severe path loss, which can severely deteriorate signal strength and thereby damage performance of wireless communications employing those frequencies. Beamforming may at least partially compensate for the severe path loss of these cm Wave and mm Wave frequencies by directing radiation in narrow beam widths toward target users, which may accordingly improve signal quality, improve coverage range, and reduce inter-user interference. 
     For a 5G Evolved Node-B (eNB) (or Access Point (AP)), Downlink (DL) transmissions may accordingly employ Transmitting (Tx) beamforming. Different Tx beams may be used to send a 5G User Equipment (UE) (or Station (STA)) specific transmissions to different UEs. In 5G systems, for signals that may be broadcast, Tx beam sweeping or aggregated Tx-beam-based transmissions may help ensure sufficient coverage for 5G cells. 
     Discussed herein are various scenarios for stand-alone 5G eNB deployments using cmWave and mmWave frequencies to send 5G System Information Block (xSIB) transmissions by sweeping across sets of Tx beams. Mechanisms for xSIB transmission with Tx beamforming are discussed. In some embodiments, xSIB transmission via sweeping across Tx beams may be employed in conjunction with Incremental Redundancy, such as through Redundancy Version patterns. For some embodiments, xSIB transmissions may be based upon a Tx beam index. 
     Scheduling of xSIB transmission is also discussed herein. In some embodiments, for xSIB transmission without resource configuration based upon 5G Physical Downlink Control Channel (xPDCCH) transmissions, resource configuration may be derived from a 5G Primary Synchronization Signal (xPSS) transmission, or a 5G Secondary Synchronization Signal (xSSS) transmission, or a 5G Master Information Block (xMIB) via 5G Physical Broadcast Channel (xPBCH). Also discussed herein are scenarios for derivation of frequency resources and subframe type used for xSIB transmission for xPDCCH-less scenarios. 
     In the following description, numerous details are discussed to provide a more thorough explanation of embodiments of the present disclosure. It will be apparent to one skilled in the art, however, that embodiments of the present disclosure may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring embodiments of the present disclosure. 
     Note that in the corresponding drawings of the embodiments, signals are represented with lines. Some lines may be thicker, to indicate a greater number of constituent signal paths, and/or have arrows at one or more ends, to indicate a direction of information flow. Such indications are not intended to be limiting. Rather, the lines are used in connection with one or more exemplary embodiments to facilitate easier understanding of a circuit or a logical unit. Any represented signal, as dictated by design needs or preferences, may actually comprise one or more signals that may travel in either direction and may be implemented with any suitable type of signal scheme.

       FIGS.  1 - 4    illustrate mechanisms for xSIB transmission with Tx beamforming. 5G Physical Downlink Shared Channel (xPDSCH) transmissions may be used to transmit xSIB. Various kinds of xSIBs may carry different types of System Information (SI). AUE may need to decode part of an xSIB, for example an xSIB1 and/or an xSIB2, before transmitting an initial access message. AUE may decode an xSIB1 transmission first and may subsequently decode an xSIB2 transmission according to scheduling information indicated by the xSIB1. Other xSIB transmissions, e.g., xSIB3 through xSIB-N, may be decoded in a manner similar to xSIB2. In some embodiments, the xSIB transmissions described may include xSIB1 transmissions only. 
     In some embodiments, xSIB may be transmitted periodically through sweeping of Tx beams. An xSIB may also be transmitted in a subframe at a subframe offset or starting subframe. In some embodiments, the period and/or subframe offset for xSIB transmissions may be configured by various elements of the wireless communication network. In some embodiments, the period and/or subframe offset for xSIB transmissions may be configured by xMIB transmissions. In some embodiments, the period and/or subframe offset for xSIB transmissions may be configured by at least one of an xPSS transmission, an xSSS transmission, and/or a Beam Reference Signal (BRS) transmission. 
       FIG.  1    illustrates a periodic xSIB transmission, in accordance with some embodiments of the disclosure.

     In scenario  100 , a number N of Tx beams may be used for the xSIB transmissions. xSIBs may be transmitted on different Tx beams at a period  104 , which may be K subframes. xSIB may also be transmitted at a subframe offset or starting subframe t.

     In one exemplary embodiment, N BRS  for an eNB may be 4, and the eNB may be operable to simultaneously transmit 4 beams (e.g., via 4 antenna panels, one or more of which may comprise an array of small antennas). Accordingly, for any given Orthogonal Frequency Division Multiplex (OFDM) symbol, the eNB may transmit beams in 4 directions at the same time. In the exemplary embodiment, N sym   BRS  may be 12, and the eNB&#39;s resources may transmit by sweeping across Tx beams oriented in various directions over 12 symbols within a subframe. In the exemplary embodiment, M may be 4, and 4 Tx beams may be aggregated (e.g., for an xSIB transmission). For the exemplary embodiment, the number N of Tx beams used for the xSIB transmissions may accordingly be 12. 
     In some embodiments, in a “single frequency network” mode of operation, multiple eNBs may transmit an xSIB simultaneously at the same time and frequency resource (e.g., at the same resource element (RE) within an RB), which may advantageously gain the benefits of multi-site diversity. In some cases, N may be 1, and aggregated Tx beams may be applied on one or more xSIB transmissions. 
       FIG.  2    illustrates a periodic xSIB sequence transmission, in accordance with some embodiments of the disclosure. A scenario  200  may comprise a sequence  210  of a number L of xSIB transmissions for a first Tx beam, a sequence  220  of the number L of xSIB transmissions for a second Tx beam, and so on, through a sequence  290  of the number L of xSIB transmissions for an Nth Tx beam Sequence  210  may comprise a first xSIB transmission  211  for the first Tx beam, sequence  220  may comprise a first xSIB transmission  221  for the second Tx beam, and sequence  290  may comprise a first xSIB transmission  291  for the Nth Tx beam Within sequence  210 , sequence  220 , and/or other sequences of xSIB transmissions through sequence  290 , a UE may expect the xSIB transmissions to be transmitted via the same Tx beam 
     In scenario  200 , a number of Tx beams N may be used for the xSIB transmissions. Within sequence  210 , sequence  220 , and/or other sequences of xSIB transmissions through sequence  290 , the xSIB transmissions may be spaced by a period  202 , which may be J subframes. The xSIB transmissions may also be transmitted at a subset offset or starting subframe t. 
     The numbers N, J, and/or t may be configured in various ways. In some embodiments, the numbers N, J, and/or t may be configured by a PCell (e.g. by RRC). In some embodiments, the numbers N, J, and/or t may be carried in and/or configured by xMIB. In some embodiments, the numbers N, J, and/or t may be configured by and/or derived from xPSS, xSSS, and/or BRS. 
     In some embodiments, for the L periodic xSIB transmissions within a sequence of xSIB transmissions, Chase Combining or Incremental Redundancy (IR) may be used. For embodiments using IR, different Redundancy Version (RV) patterns may be applied to improve decoding performance. In some embodiments, xSIB transmissions may use an RV pattern that may be predefined as [0 2 3 1], in accordance with, e.g., Release 12 of the 3GPP LTT specification (frozen 2011 Jun. 26). With the same Tx beams applied on the L periodic xSIB transmissions, a UE may perform IR (within a number P of transmissions) to improve detection performance. 
     In a manner that may be substantially similar to scenario  100 , in some embodiments, in a “single frequency network” mode of operation, multiple eNBs may transmit an xSIB simultaneously at the same time and frequency resource (e.g., at the same resource element (RE) within an RB). In some such embodiments, aggregated Tx beams may be applied on each xSIB transmission, and RV pattern [0 2 3 I] may be applied to improve decoding performance. 
       FIG.  3    illustrates a periodic interleaved consecutive xSIB sequence transmission, in accordance with some embodiments of the disclosure. A scenario  300  may comprise a sequence  310  of xSIB transmissions for a first Tx beam, a sequence  320  of xSIB transmissions for a second Tx beam, and so on, through a sequence  390  of xSIB transmissions for an Nth Tx beam Sequence  310  may comprise a first xSIB transmission  311  for the first Tx beam, sequence  320  may comprise a first xSIB transmission  321  for the second Tx beam, and sequence  390  may comprise a first xSIB transmission  391  for the Nth Tx beam 
     The first xSIB transmissions of sequence  310 , sequence  320 , and/or other sequences of xSIB transmissions through sequence  390  may be transmitted in N consecutive symbols or subframes. Accordingly, first xSIB transmission  311  (of sequence  310 , for the first Tx beam) may be transmitted in a first symbol or subframe, and first xSIB transmission  321  (of sequence  320 , for the second Tx beam) may be transmitted in a second symbol or subframe, and so on, consecutively, through first xSIB transmission  391  (of sequence  390 , for the Nth Tx beam), which may be transmitted in an Nth symbol or subframe. In addition, a UE may decode repeated xSIB transmissions together. 
     In scenario  300 , a number of Tx beams N may be used for the xSIB transmissions. Within sequence  310 , sequence  320 , and/or other sequences of xSIB transmissions through sequence  390 , the first xSIB transmission and the second xSIB transmission of the sequence may be spaced by a period  302 , which may be a number J of subframes, for which J may be larger than N. The xSIB transmissions may also be transmitted at a subset offset or starting subframe t. 
     The numbers N, J, and/or t may be configured in various ways. In some embodiments, the numbers N, J, and/or t may be configured by a PCell (e.g. by RRC). In some embodiments, the numbers N, J, and/or t may be carried in and/or configured by xMIB. In some embodiments, the numbers N, J, and/or t may be configured by and/or derived from xPSS, xSSS, and/or BRS. 
       FIG.  4    illustrates a periodic non-interleaved consecutive xSIB sequence transmission, in accordance with some embodiments of the disclosure. A scenario  400  may comprise a sequence  410  of a number L of xSIB transmissions for a first Tx beam, a sequence  420  of the number L of xSIB transmissions for a second Tx beam, and so on, through a sequence of the number of L xSIB transmissions for an Nth Tx beam Sequence  410  may comprise a first xSIB transmission  411  for the first Tx beam, sequence  420  may comprise a first xSIB transmission  421  for the second Tx beam, and the sequence of xSIB transmissions for the Nth Tx beam may comprise a first xSIB transmission for the Nth Tx beam In addition, a predetermined or configured RV pattern may be employed to improve decoding performance. 
     Within sequence  410 , sequence  420 , and/or other sequences of xSIB transmissions through the sequence for the Nth Tx beam, the L xSIB transmissions of each sequence may be transmitted in L consecutive symbols or subframes. Accordingly, first xSIB transmission  411  of sequence  410  may be transmitted in a first symbol or subframe, and a second xSIB transmission of sequence  410  may be transmitted in a second symbol or subframe, and so on, consecutively, through an Lth xSIB transmission of sequence  410 , which may be transmitted in an Lth symbol or subframe. 
     In scenario  400 , a number of Tx beams N may be used for the xSIB transmissions. Within sequence  410 , sequence  420 , and/or other sequences of xSIB transmissions through the Nth sequence, the first xSIB transmissions of each sequences may be spaced from each other by a period  404 , which may be K subframes, and K may be larger than N. The xSIB transmissions may also be transmitted at a subset offset or starting subframe t. 
     With reference to  FIGS.  1 - 4   , in some embodiments, Tx beam information for an xSIB transmission may be derived from a Tx beam applied on an xMIB transmission or a BRS transmission. Based upon that information, a UE may decide which subframe in which to decode an xSIB. A number k (for which k E [1, N]) may be denoted as an index of an xSIB targeted for decoding, and may be indicated by BRS information as in equation 2 below:
 
 k=f ( N   ID   BRS   ,I   BRS )  (2)
         Where:   f( ) may be a mapping function (which may be defined by the network);       

     N ID   BRS  may indicate an ID of a BRS sequence in which a maximum BRS Receiving Power (BRS-RP) may be measured by a UE; and
         I BRS  may denote an RB group index for the BRS (which may define a relationship between two or more of an OFDM symbol for a BRS transmission, an RB group index for the BRS transmission, and a Tx beam index for xSIB transmission).   An exemplary mapping function f( ) may result in equation 3 below (where N/y may refer to a number of symbols for BRS within one subframe, as in equation 1 above).

     AUE may derive a periodic subframe which may contain an xSIB transmission for safe decoding based on the above equations and relationships. For example, k may indicate an index of a symbol or subframe in which a UE may expect an xSIB transmission for a particular Tx beam. The UE may accordingly target to decode the expected xSIB transmission at a subframe corresponding to the index k. 
       FIG.  5    illustrates a self-contained Time Division Duplex (TDD) subframe structure, in accordance with some embodiments of the disclosure. To enable low-latency transmissions, a self-contained TDD subframe structure may be used for a 5G system A Hybrid Automatic Repeat Request (HARQ) acknowledgement (ACK)|negative-acknowledgement (NACK) feedback may be transmitted in a subframe in which an xPDSCH is scheduled. 
     In  FIG.  5   , a subframe  500  may comprise an xPDCCH transmission  510 , an xPDSCH transmission  520 , a guard time  530 , and a 5G Physical Uplink Control Channel (xPUCCH) transmission  540 . xPDSCH transmission  520  may be scheduled by xPDCCH transmission  510 , and may be transmitted immediately subsequent to xPDCCH transmission  510 . AUE may decode xPDSCH transmission  520 , after which the UE may provide an ACK or NACK as feedback in xPUCCH transmission  540 . In some embodiments, a guard time  530  may be present between xPDSCH transmission  520  and xPUCCH transmission  540  in order to accommodate DL-to-UL and/or UL-to-DL switching times and/or round-trip propagation delays. 
     With reference to  FIGS.  1 - 5   , xSIB transmissions may be scheduled in a variety of ways. In some embodiments, xSIB transmissions may be scheduled via xPDCCH transmissions. A Downlink Control Information (DCI) format with DL assignment may include a Modulation and Coding Scheme (MCS) indicator, an RB assignment indicator, and/or one or more others indicators. The xPDCCH transmission and the subsequent xPDSCH transmission carrying an xSIB may be transmitted by the same Tx beam In some embodiments, an xPDCCH transmission may be used to transmit the DCI for other, common information, such as paging, RAR, power control commands, and/or some DE-specific DCI. Moreover, in cases in which Tx beam sweeping may be applied for xPDCCH transmissions with common search space, repeated transmissions may be advantageous, but may increase system overhead and thereby reduce spectrum efficiency. 
     Accordingly, in some embodiments, xPDCCH-less operation for xSIB transmission may reduce system overhead and reserve more beam resources for other messages (e.g., UE specific DCI). For xPDCCH-less operation, information regarding resource allocation and MCS may be made available at a UE (e.g., a Machine-Type Communication (MTC) UE) in order to facilitate proper decoding of common control channels. The configuration of the resource allocation may include various parameters, such as:
         a bitmap of subframes used for xSIB transmission;   a starting subframe (e.g., with respect to a System Frame Number (SFN) 0 of the transmitting cell and/or a period of the xSIB);   a frequency location of an xSIB transmission;   a configuration of an xSIB transmission (e.g., a number of repeated subframes, a type (e.g. Chase Combining or Incremental Redundancy), and/or an RV pattern used for xSIB transmission);   a parameter for frequency hopping (e.g., a frequency hopping enable, or a frequency hopping pattern);   a starting ODFM symbol for xSIB transmission; an xPDSCH duration for xSIB transmission;   a duration of xPUCCH transmission; and/or   a configuration parameter (e.g., an xPUCCH presence indicator for the subframe in xSIB transmission).       

     In some embodiments, various resource allocation parameters may be predetermined, e.g., by being defined in a specification. For example, a time instance for xSIB transmission may be fixed by specification (e.g., every subframe number 5 within a 20 millisecond period). For some embodiments, one or more resource allocation parameters and/or an MCS of an xSIB transmission may be configured by higher layers via RRC signaling from a PCell. 
     In some embodiments, one or more resource allocation parameters and/or an MCS may be carried in an xMIB transmission. For example, a limited set of MCS and frequency locations used for xSIB transmission may be defined by specification. One or more fields of an xMIB transmission may indicate one or more combinations of MCS and frequency locations that may be applied for xSIB transmission. 
     For some embodiments, one or more resource allocation parameters and/or an MCS of an xSIB transmission may be derived from xPSS, xSSS, and/or BRS. For example, a frequency location used for xSIB transmission may be defined as a function of cell ID, virtual cell ID, BRS group ID, SFN, subframe index, and/or slot index. In another example, a set of possible frequency resources for xSIB transmission may be predefined or configured in an xMIB transmission. Furthermore, an exact frequency resource used for xSIB transmission may be derived from this set of possible frequency resources according to a function of physical cell ID and/or subframe index. 
     In one example, a frequency resource index/freq may be generically defined in accordance with equation 4 below:
 
 I   freq =( c   0   ·N   cell   ID   +c   1   ·n   SF   +c   2 )mod  K   freq   (4)
         Where:   c 0 , c 1 , c 2  may be constants (which may be, e.g., predefined in the specification, or configured by higher layers via xMIB);   N Cell   ID  may be a physical cell ID;   n sF  may be a subframe index;   mod may be a modulo operation; and   K freq  may be frequency resources configured in an xMIB (e.g., a number of frequency resources).       

     In some embodiments, one or more of the above-described methods may be combined to indicate resource allocation parameters and/or MCS of an xSIB transmission. 
       FIG.  6    illustrates a Media Access Control (MAC) Protocol Data Unit (PDU) for Random Access Response (RAR) and xSIB, in accordance with some embodiments of the disclosure. A MAC PDU  600  may comprise a MAC header  610 , a first RAR  621 , a second RAR  622 , additional RARs through an Nth RAR  629 , an xSIB  630 , and/or an optional padding  640 . 
     For some embodiments, xSIB may be transmitted after a 5G Physical Random Access Channel (xPRACH) transmission and may be associated with RAR. MAC header  610  may be an independent xSIB MAC header, and may be used to indicate the xSIB transmission, in which a new Logical Channel ID (LCID) denoting the xSIB transmission may be used. AUE may decode one or more RARs (e.g., of first RAR  621  through Nth RAR  629 ) and/or xSIB  630  of MAC DPU  600 . For an RRC connected UE, if information in an xSIB (e.g., xSIB  630 ) changes, an eNB may transmit the changed information to one or more active UEs (and potentially to all active UEs) via MAC PDU  600 , with an SI Radio Network Temporary Identifier (RNTI) by xPDSCH in several subframes. 
       FIG.  7    illustrates a 5G eNB and a 5G UE, in accordance with some embodiments of the disclosure.  FIG.  7    includes block diagrams of an eNB  710  and a UE  730  which are operable to co-exist with each other and other elements of an LTE network.

Wireless interface  742  may be arranged to allow the processor to communicate with another device. Display  744  may provide a visual and/or tactile display for a user to interact with UE  730 , such as a touch-screen display.

     Accordingly, in some embodiments, UE  730  may be a device comprising an application processor, a memory, one or more antennas, a wireless interface for allowing the application processor to communicate with another device, and a touch-screen display. 
     Elements of  FIG.  7   , and elements of other figures having the same names or reference numbers, can operate or function in the manner described herein with respect to any such figures (although the operation and function of such elements is not limited to such descriptions). For example,  FIGS.  8  and  11    also depict embodiments of eNBs, hardware processing circuitry of eNBs, UEs, and/or hardware processing circuitry of UEs, and the embodiments described with respect to  FIG.  7    and  FIGS.  8  and  11    can operate or function in the manner described herein with respect to any of the figures. 
     In addition, although eNB  710  and UE  730  are each described as having several separate functional elements, one or more of the functional elements may be combined and may be implemented by combinations of software-configured elements and/or other hardware elements. In some embodiments of this disclosure, the functional elements can refer to one or more processes operating on one or more processing elements. Examples of software and/or hardware configured elements include Digital Signal Processors (DSPs), one or more microprocessors, DSPs, Field-Programmable Gate Arrays (FPGAs), Application Specific Integrated Circuits (ASICs), Radio-Frequency Integrated Circuits (RFICs), and so on. 
     An eNB may include various hardware processing circuitries discussed below (such as hardware processing circuitry  800  of  FIG.  8   ), which may in tum comprise logic devices and/or circuitry operable to perform various operations.

     In some embodiments, the UE  1100  comprises a plurality of power saving mechanisms. If the UE  1100  is in an RRC_Connected state, where it is still connected to the eNB as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the device may power down for brief intervals of time and thus save power. 
     If there is no data traffic activity for an extended period of time, then the UE  1100  may transition off to an RRC_Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The UE  1100  goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. Since the device might not receive data in this state, in order to receive data, it should transition back to RRC_Connected state. 
     An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable. 
     Reference in the specification to “an embodiment,” “one embodiment” “some embodiments,” or “other embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments. The various appearances of “an embodiment,” “one embodiment,” or “some embodiments” are not necessarily all referring to the same embodiments. If the specification states a component, feature, structure, or characteristic “may,” “might,” or “could” be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to “a” or “an” element, that does not mean there is only one of the elements. If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional element. 
     Furthermore, the particular features, structures, functions, or characteristics may be combined in any suitable manner in one or more embodiments. For example, a first embodiment may be combined with a second embodiment anywhere the particular features, structures, functions, or characteristics associated with the two embodiments are not mutually exclusive. 
     While the disclosure has been described in conjunction with specific embodiments thereof, many alternatives, modifications and variations of such embodiments will be apparent to those of ordinary skill in the art in light of the foregoing description.

     In addition, well known power/ground connections to integrated circuit (IC) chips and other components may or may not be shown within the presented figures, for simplicity of illustration and discussion, and so as not to obscure the disclosure. Further, arrangements may be shown in block diagram form in order to avoid obscuring the disclosure, and also in view of the fact that specifics with respect to implementation of such block diagram arrangements are highly dependent upon the platform within which the present disclosure is to be implemented (i.e., such specifics should be well within purview of one skilled in the art). Where specific details (e.g., circuits) are set forth in order to describe example embodiments of the disclosure, it should be apparent to one skilled in the art that the disclosure can be practiced without, or with variation of, these specific details.
