Abstract: Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for management and/or support of multimedia broadcast multicast service (MBMS) service in a wireless communications network. An evolved Node B (eNB) may transmit MBMS assistance information to a user equipment (UE). The MBMS assistance information may identify a carrier by which one or more upcoming MBMS services are to be provided and an indicator of a carrier selection mode to be used by the UE. The UE may transmit an MBMS interest indication message including information related to one or more targeted MBMS services which the UE wants to receive.

Abstract: Briefly, in accordance with one or more embodiments, user equipment receives unicast services from a first carrier of a primary serving cell and determines if Multimedia Broadcast and Multicast services (MBMS) services are available on a second carrier based at least in part on information in a broadcast carrier channel that indicates the second carrier or an identification (ID) of the second carrier. If MBMS services are available on the second carrier, the user equipment at least temporarily switches to the second carrier to receive the MBMS services. The user equipment may provide feedback to the network or the primary serving cell when it starts and stops receiving MBMS services, and then may switch back to the primary serving cell when MBMS services have ended or the user equipment no longer desires to receive MBMS services.

Abstract: A method of determining reference signal received power (RSRP) by user equipment (UE) associated with a distributed antenna system (DAS) may include detecting at least three different reference signals in one or more common reference signals (CRSs) that are associated with different antennas in the DAS. The method may also include determining at least three different RSRPs corresponding to the at least three different reference signals. The at least three different RSRPs may be level 3 filtered to produce at least three corresponding filtered powers. The UE may report a maximum of the at least three corresponding filtered powers to the distributed antenna system.

Abstract: A system and method for multiplexing subchannels in an OFDMA network is provided. The subchannels can be multiplexed by splitting the subchannels in the frequency domain. Alternatively, the subchannels can be code division multiplexed using N orthogonal spreading codes. The subchannel multiplexing increases system capacity for low-rate services, such as voice-based services.
