Abstract: A cell transmits synchronization signal blocks (SSB) to a user equipment (UE) for the UE to synchronize with the cell. The cell configures a discovery reference signal (DRS) window for synchronization signal block (SSB) transmission to a user equipment (UE), determines that a channel in an unlicensed spectrum is not occupied and transmits multiple SSBs to the UE in response to determining that the channel in the unlicensed spectrum is not occupied.

Abstract: Embodiments of the present disclosure relate to uplink transmission with repetitions. According to embodiments of the present disclosure, a user equipment (UE) comprises a transceiver configured to communicate with a network; and a processor communicatively coupled to the transceiver and configured to perform operations. The operations comprise determining first Channel State Information (CSI) and second CSI based on at least one of a previous channel and interference measurement or a latest channel and interference measurement. The operations further comprise transmitting the first CSI via the transceiver to the network with a first beam, the first CSI multiplexed with a first repetition of an uplink transmission with the first beam. The operations further comprise transmitting the second CSI via the transceiver to the network with a second beam, the second CSI multiplexed with a second repetition of the uplink transmission with the second beam.

Abstract: A cell performs beam management operations for a user equipment (UE). The cell transmits a first group of multiple reference signals via a first transmission reception point (TRP) to a user equipment (UE), transmits a second group of multiple reference signals via a second different TRP to the UE, receives an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group and transmits downlink data to the UE using the first beam and the second beam.

Abstract: Supporting transmission of multiple hybrid automatic repeat request acknowledgments (HARQ-ACKS) within a single slot may include encoding a first HARQ-ACK and a second HARQ-ACK within the single slot for transmission to a base station. The first HARQ-ACK may be transmitted via a first physical uplink control channel (PUCCH) and the second HARQ-ACK may be transmitted via a second PUCCH. Based on encoding the first HARQ-ACK and the second HARQ-ACK within the single slot, one or more additional uplink (UL) signals colliding with at least one of the first HARQ-ACK and the second HARQ-ACK within the single slot may be responded to based on a configuration of the UE.
