    Abstract: Approaches are described that enhance the reliability of physical downlink control channel (PDCCH) detection where the PDCCH can be transmitted repeatedly with different beams. The approaches use soft combining where the user equipment (UE) combines the soft bits from each repetition, with the combined soft bits used to jointly decode the PDCCH repetitions. To support the soft combining, the UE needs to buffer the soft bits. Buffering approaches include determining what contributes towards the buffering, including scenarios where one of the linked search sets (SSs) is dropped, what is contributed in a linked SS set pair, how the duration of buffer counting is determined, and how the UE reports its maximum buffer size capability. In scenarios where the required buffer size exceeds the UE maximum buffer size, a priority rule may be used in the PDCCH decoding using the SS sets pair, where the priority is based on the SS type, the serving cell index, the SS set ID and/or the control channel resource set (CORESET) ID.

    Abstract: Embodiments of the present disclosure relate to downlink data reception operation. According to embodiments of the present disclosure, a baseband processor of a user equipment (UE) is configured to perform operations comprising receiving Downlink Control Information (DCI) through more than one beams from at least one from at least one TRP; determining a DCI transmission scheme for the received DCI, wherein the DCI transmission scheme is configured by an upper layer signaling, and wherein the DCI transmission scheme is one of a Single Frequency Network (SFN) scheme, a non-SFN scheme, and a hybrid scheme, wherein the DCI is transmitted using both SFN scheme and non-SFH scheme in the hybrid scheme; determining whether the received DCI indicates a Transmission Configuration Indicator (TCI) for PDSCH reception from the at least one TRP or not. The operations further comprise in accordance with a determination that the received DCI fails to indicate the TCI and based on the determined DCI transmission scheme, selecting at least one TCI for the PDSCH reception from candidate TCIs configured for one or more Control Resource Sets (CORESETs) associated with the DCI.

    Abstract: A user equipment (UE) is configured to transmit physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) transmissions. The UE receives a downlink control information (DCI) transmission including a transmission power control (TPC) configuration, wherein the TPC configuration includes at least one TPC command, determines a subset of (i) multiple closed loop indexes or (ii) multiple beams for which the TPC command is configured, wherein the multiple closed loop indexes and multiple beams correspond to multiple transmission and reception points (TRPs) and applies the TPC command to one or more physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) transmissions corresponding to the subset of multiple closed loop indexes or beams.
