Abstract: Interference measurement may include decoding a channel state information (CSI) reporting configuration received from a base station. The CSI reporting configuration may be associated with a set of resources for interference measurement. The first UE may be in communication with at least a first transmission and reception point (TRP) of a plurality of TRPs and at least a second TRP of the plurality of TRPs may also be in communication with a second UE that creates cross-link interference for the first UE. At the first UE, a cross-link interference measurement associated with the second UE may be performed using the CSI reporting configuration.

Abstract: A user equipment (UE), a base station, a baseband processor or other network device can determine a codebook subset configuration of a plurality of multiple-input multiple-output (MIMO) layers for antenna ports of a codebook. The codebook subset configuration can include a nested structure based on a codebook configured for a fully-coherent UE, or a codebook configured for a partially-coherent UE. Fully-coherent precoders, a set of partially-coherent precoders or a set of non-coherent precoders can be configured in the codebook subset configuration to reduce a number of precoders from the partially-coherent precoders or the non-coherent precoders.

Abstract: Systems, methods, and circuitries are provided for supporting blind retransmission. In one example, a method includes processing control information that indicates resources for communication of a physical downlink shared channel or a physical uplink shared channel (PDSCH/PUSCH) transmission and timing information for a retransmission of the PDSCH/PUSCH. The method includes configuring operation to: receive the PDSCH/PUSCH transmission based on the resources; and determine that a subsequent PDSCH/PUSCH received at a subsequent time corresponds to the retransmission of the PDSCH/PUSCH when the subsequent time coincides with the indicated timing information for the retransmission and, in response combine the PDSCH/PUSCH with the retransmission in a HARQ buffer for decoding purposes.

Abstract: A user equipment (UE) and a base station exchange communications to enable the UE to switch beams. The UE receives a physical uplink control channel (PUCCH) resource configuration from the base station, wherein the PUCCH resource configuration includes a plurality of PUCCH resources, receives a signal from the base station based on which one of the plurality of PUCCH resources is activated, performs a beam switching operation to change a transmission beam to a beam corresponding to the activated PUCCH resource and transmits periodic uplink (UL) data using the beam corresponding to the activated PUCCH resource.

Abstract: Methods and devices for a UE to multiplex uplink control information (UCI). The UE establishes a connection with a base station. The UE determines whether to multiplex first UCI by first identifying whether intra-priority timing overlap exists between the timing resources of the first UCI and a PUSCH with the same priority. Subsequently, the UE identifies whether inter-priority timing overlap exists between the timing resources of the first UCI and a second PUCCH with a different priority from the first PUCCH. Finally, the UE identifies whether the timing resources of the first UCI overlap with a second PUSCH with a different priority than the first PUCCH. The UE multiplexes the first UCI based on the determination whether to multiplex the first UCI, and transmits the multiplexed first UCI to the base station.

Abstract: Dynamic scheduling can be performed by 5G new radio in the licensed or unlicensed band. A base station can poll user equipment (UE) by transmitting a downlink control information (DCI) or other downlink communication that indicates resources that a UE can use to send a scheduling request. The resources are dynamic, e.g., they can be updated and allocated to UEs based on network conditions. Other aspects are described.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for channel occupancy rate determination of a channel between a user equipment (UE) and a base station in an unlicensed spectrum. A UE can perform measurements based on a measurement configuration from the base station, and further determine a channel occupancy rate of the channel based on the performed measurements. The measurement configuration indicates to the UE to perform an omni measurement or a directional measurement by using an antenna element of the UE. The UE can further transmit a report to the base station to indicate the channel occupancy rate.
