Abstract: Embodiments are disclosed for capability reporting for antenna switching, AS, sound reference signals, SRS. A user equipment (UE) can transmit a capability report for AS SRS that includes a plurality of receive antenna (e.g., six or eight receive antenna), and receive SRS instructions based on the capability report. The UE can transmit a first temporary capability reduction for a duration, and transmit a first SRS according to the first temporary capability reduction and the SRS instructions, while maintaining phase continuity. To maintain phase continuity, the UE can calibrate one or more SRS ports participating in the AS SRS to transmit with substantially a same transmit power. The UE can determine that a second SRS overlaps an other transmission in a time domain, determine that the other transmission has an absolute priority over the second SRS, and transmit the other transmission but not the second SRS.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE receives a configuration for a physical downlink control channel (PDCCH) including repetitions for PDCCH candidates comprising first PDCCH data, wherein the PDCCH candidates are repeated across multiple durations of a DL resource grid, detects, based on a repetition detection scheme, each of the PDCCH candidates and combines soft bits from each of the PDCCH candidates, wherein the combined soft bits are jointly decoded to determine the first PDCCH data and calculates a number of blind decodes (BDs) for the durations of the DL resource grid carrying the PDCCH candidates, wherein at least one BD value for the PDCCH candidates is scaled by a scaling factor for the calculation of the number of BDs.

Abstract: A user equipment is configured to connect to a base station (BS) over a shared channel subject to channel access operations. The UE receives a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), determines that no downlink (DL) transmissions are detected during a predefined time of the BS-FFP and determines that at least one condition associated with an uplink (UL) transmission is satisfied. When no downlink (DL) transmissions are detected during the predefined time of the BS-FFP and the at least one condition is satisfied, the UE performs a UE-initiated channel access operation. When the UE-initiated channel access operation is successful, the UE performs the UL transmission during the UE-FFP.

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station and a processor communicatively coupled to the transceiver. The processor is configured to determine one or more configured grant (CG) transport blocks (TBs) of one or more CG uplink transmissions and determine one or more dynamic grant (DG) TBs of one or more DG uplink transmissions. The processor is further configured to determine that a first CG TB of the one or more CG TBs overlaps with a first DG TB of the one or more DG TBs in time and determine that a priority level of the first CG TB is lower than a priority level of the DG TB. The processor is further configured to determine that the priority level of the first CG TB is lower than the priority level of the first DG TB and transmit, in the first DG TB, a first DG uplink transmission corresponding to the first DG TB.
