    摘要： Methods, systems, and devices for wireless communications are described for concurrent communications between multiple transmission-reception points (TRPs) and a user equipment (UE). A default beam for each of the TRPs may be determined, and in the case that the default beams are unable to be concurrently received at the UE, a prioritization rule may be applied to determine which TRP uses the initially determined default beam, where the other TRP(s) may use a different beam. A UE also may be configured with a subset of control resource sets for each TRP, such that beams associated with different configured subsets are compatible and able to be concurrently received at the UE. Other techniques for providing compatibility between beams of multiple concurrent TRP transmissions include determination of a first beam, and selection of a second beam based on a mapping to the first beam, or explicit configuration by a base station.

    摘要： The invention relates to a method and apparatus for MBMS broadcast announcement. The UE receives a protected broadcast announcement (1008) and communicates based on the broadcast announcement. The broadcast announcement is at least one of integrity protected or encrypted based on a credential known by the UE and stored on a smartcard in the UE. The UE verifies the integrity and/or decrypts the announcement based on the credential, for example MSK (1012). The announcement may include a reception report configuration and the UE sends a reception report to the server based on the reception report configuration (1018).

    摘要： Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same subframe. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.

    摘要： A method of wireless communication includes generating a list of cells for physical broadcast channel (PBCH) decoding (610). The method also includes allocating memory for decoding and cancelling a subset of cells from the generated cell list (612). The method further includes storing information related to subsets of cells from the generated list in the allocated memory (614) during different time periods. The allocated memory is sufficient for attempting, at each time period, decoding of each subset of cells and cancelling of decoded cells in each subset. The method further includes cycling through the generated cell list by processing each subset of the cell list (616) during the different time periods.

    摘要： Carrier aggregation to enhance Evolved Multimedia Broadcast Multicast Service (eMBMS) including allocating subframes used for Multimedia Broadcast/Multicast Service(MBMS), on a Single Frequency Network(MBSFN), of a wireless communications system, wherein at least a portion of one or more subframes otherwise reserved for unicast subframes on a mixed carrier are allocated to provide an increased allocation of subframes carrying MBSFN information, and transmitting MBSFN signals on the increased allocation of subframes, and interpreting subframes used for MBMS on a MBSFN of a wireless communication system. Wherein it is determined that an MBSFN signal has an increased allocation of subframes carrying MBSFN information, wherein one or more subframes previously reserved for unicast signals is allocated instead to multicast signals, the MBSFN signal is decoded according to the increased allocation to provide a multicast output.
