Abstract: The present disclosure presents a method and apparatus for identifying an access point (AP) for selection by an access terminal (AT). For example, the method may include receiving a probe request by one or more APs from an AT, wherein the probe request is broadcasted by the AT to the one or more APs, generating load information and Received Signal Strength Indicator (RSSI) values of the probe request at the one or more APs, identifying an AP of the one or more APs for selection by the AT, wherein the AP for selection by the AT is identified by the one or more APs based at least on the load information and RSSI values generated at the one or more APs, and transmitting information of an AP identified by the one or more APs to the AT. As such, an improved mechanism for selecting an access point may be achieved.

Abstract: Techniques are provided for managing simultaneous unicast and multicast/broadcast services. For example, there is provided a method operable by a user equipment (UE) or the like, that involves transmitting, upon initial connection with a wireless communication system, a first message indicating one or more capabilities of the UE. The method may further involve transmitting a second message indicating that the UE is receiving or is about to receive a multicast/broadcast service. The method may also involve receiving, as a result of the second message, data scheduled in accordance with one or more predetermined rules.

Abstract: In a method of scheduling frames, a first channel of a plurality of channels is selected for a first frame. The first frame is sent across a media-independent interface to a physical-layer device for transmission on the first channel. A data rate of the media-independent interface is greater than a data rate of the physical-layer device for the first channel. After the first frame is sent across the media-independent interface, subsequent sending of frames for the first channel across the media-independent interface is disabled for a period of time that is based at least in part on rate adaption from the data rate of the media-independent interface to the data rate of the physical-layer device for the first channel.

Abstract: A network device includes a plurality of physical-media entities (PMEs), each corresponding to a distinct channel, to generate transmit signals based on transmit packets received over a media-independent interface. The network device also includes a channel-bonding sublayer to direct the transmit packets from the media-independent interface to respective PMEs of the plurality of PMEs. The channel-bonding sublayer has a substantially fixed delay between the media-independent interface and the plurality of PMEs for the transmit packets.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use a measurement procedure for beam detection within an existing cell. The UE perform a search procedure for a first synchronization signal block (SSB) to detect a first beam of a base station. The UE may determine a first timing offset for the first SSB based on the search procedure. The UE may estimate a second timing offset for a second SSB from the base station based on the first timing offset. The UE may perform a measurement procedure for the second SSB to detect a second beam of the base station based on the second timing offset. The UE may prune fake beams based on synchronization signals used for the measurement procedure.

Abstract: A coax line terminal (CLT) transmits allocations of upstream bandwidth to a plurality of coax network units (CNUs). In response to the allocations, the CLT receives frames with data in a plurality of physical resource blocks that each correspond to a distinct set of subcarriers. The plurality of physical resource blocks includes a first group of physical resource blocks that all have a first constant allowed capacity. Sizes and modulation orders of respective physical resource blocks in the first group vary as defined by a first modulation profile. The data in the first group are received from one or more CNUs that are assigned the first modulation profile.

Abstract: Transfer of Multimedia Broadcast/Multicast Services (MBMS) over a Single Frequency Network (MBSFN) service and idle mode unicast service for a mobile entity from a source base station to a target base station may be managed by a base station or mobile entity of a cellular wireless communications system (WCS). Operations related to the transfer may include obtaining an MBMS status of the mobile entity, and/or obtaining MBMS support information for the base station. A network entity may facilitate MBMS discovery by a mobile entity, by transmitting a data element to the mobile entity including service identifiers mapped to corresponding cell identifiers to indicate respective MBMS services to be broadcast in an WCS area on adjacent cells identified by respective ones of the cell identifiers. The MBMS services may be broadcast within the WCS area using the adjacent cells previously indicated in the data element.
