Abstract: A base station and a UE may communicate using directional beams, such as a downlink directional beam (used to transmit downlink channels) and an uplink directional beam (used to transmit uplink channels), each beam carrying one or more data channels, control channels, and/or reference signals. According to one aspect, signaling for managing the uplink channels and downlink channels may be sent over a shared common beam. The shared common beam is distinct from the uplink directional beam and the downlink directional beam. In one example, a first shared common channel may serve to manage or update uplink data channels (on the uplink directional beam) and downlink data channels (on the downlink directional beam), while a second shared common channel may serve to manage or update uplink control channels (on the uplink directional beam) and downlink control channels (on the downlink directional beam).

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for dynamically updating a set of cells activated to serve a user equipment (UE) and synchronizing with the cells activated to serve the UE. An example method generally includes receiving, from a network entity, signaling indicating a set of cells supported by one or more distributed units (DUs) under a common central unit (CU) and one or more timing advance groups (TAGs) for the set of cells; identifying a subset of the set of cells activated to serve the UE; receiving physical (PHY) layer or medium access control (MAC) layer mobility signaling; updating the subset of activated cells based on the mobility signaling; and communicating with the subset of activated cells based on a timing advance associated with the one or more TAGs in which the updated subset of activated cells belong.

Abstract: Disclosed are techniques for handling of radio frequency front-end group delays (GDs) for round trip time (RTT) estimation. In an aspect, a network entity determines information indicating a network total GD and a user equipment (UE) determines information indicating a UE total GD. The network entity transmits one or more RTT measurement (RTTM) signals to the UE, each including a RTTM waveform. The UE determines one or more one or more RTT response (RTTR) payloads for one or more RTTR signals, each including a RTTR waveform. The UE transmits the RTTR signal(s) to the network entity. For each RTTR signal, a transmission time of the RTTR waveform and/or the RTTR payload is/are determined based on the UE total GD. The network entity determines a RTT between the UE and the network entity based on the RTTM signal(s), the RTTR signal(s), and the information indicating the network total GD.

Abstract: Aspects of disclosure relate to a network node for changing a physical cell identifier (PCI). The network node transmits a first signal based on a first PCI during a first synchronization signal block (SSB) occasion, transmits a second signal based on the first PCI during a second SSB occasion, and transitions from the first PCI to a second PCI. During a transition period, the network node transmits the first signal based on the second PCI during the first SSB occasion, and continues to transmit the second signal based on the first PCI during the second SSB occasion. After an end of the transition period, the network node continues to transmit the first signal based on the second PCI during the first SSB occasion, and ceases transmission of the second signal based on the first PCI during the second SSB occasion. Other aspects and features are also claimed and described.

Abstract: To provide a more robust connection and better coverage, a UE may be configured to receive an SFN PDSCH through a plurality of beams from a plurality of TRPs including a first TRP and a second TRP, the plurality of beams being based on configured DL TCI states. The UE may be further configured to transmit a same PUSCH through each of the plurality of beams. In addition, the same PUSCH may be transmitted through a first beam of the plurality of beams n times, and transmitted through a second bream of the plurality of beams m times, where n and m are integers greater than or equal to one.

Abstract: A user equipment (UE) receives a configuration from a base station for receiving multiple repetitions of a transmission in a slot aggregation. The UE receives an indication indicating one or more beams used for the multiple repetitions of the transmission. The UE receives a first repetition of the transmission in a first slot based on single frequency network (SFN) operation using at least one configuration that is different from a configuration used for receiving a second repetition in a second slot based on non-SFN operation. The UE optionally determines, based on the indication, whether repetitions within the multiple repetitions of the transmission are transmitted by the base station based on the SFN operation or the non-SFN operation.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a user equipment (UE) and/or base station. In one aspect, the apparatus may monitor for a paging physical downlink control channel (PDCCH) and a paging message. The apparatus may also receive the paging PDCCH including paging downlink control information (DCI), where the paging DCI is associated with the paging message. The apparatus may also receive the paging message, where at least one of the paging DCI or the paging message is received more than once. In another aspect, the apparatus may transmit a paging PDCCH including paging DCI, where the paging DCI is associated with a paging message. The apparatus may also transmit the paging message, where at least one of the paging DCI or the paging message is transmitted more than once.
