Abstract: A user equipment (UE) having a first capability associated with a lower maximum UE bandwidth than a second capability performs at least a part of initial access based on an initial downlink bandwidth part (BWP) that is shared among UEs having the first capability and UEs having the second capability. The UE switches, after the initial access, to an active downlink BWP and an active uplink BWP that are dedicated for the UEs having the first capability to perform random access, paging, system acquisition, measurement and data communication procedures.

Abstract: In an aspect, a BS is configured as a serving cell of a UE. The BS transmits data to the UE in accordance with a frequency hopping scheme over a first set of T-F resources of a first BWP and a second set of T-F resources of a second BWP. The BS (or another BS) further transmits, to the UE over a third BWP that is different than the second BWP, a PDCCH including a PI field with a PI associated with the transmitted data over the second set of T-F resources of the second BWP. The UE receives the data and the PDCCH. The UE processes the received data over (at least) the second set of T-F resources based on the PI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability report to a base station indicating a triggering offset. The base station may configure the UE with one or more channel state information (CSI) measurement resources and send downlink control information (DCI) that triggers an aperiodic CSI report for some of the CSI measurement resources. The UE may report CSI by measuring the CSI resources after the triggering offset. In some cases, CSI reporting related to the different codebook types (e. g., Type I, Type II) may be modified, where after identifying a type of codebook and determining which type of codebook to process (e. g., based on a number of CSI processing units), the UE may identify a priority associated with different CSI reports. The UE may be configured with various parameters that relax or modify the processing of Type II CSI reports.

Abstract: Various aspects of the present disclosure generally relate to multi-slot transmission time interval based channel state information (CSI) and uplink shared channel (UL-SCH) multiplexing. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message and determine, based at least in part on the DCI message, a schedule for multiplexing UL-SCH data and one or more components of uplink control information (UCI) in a plurality of slots on a physical uplink shared channel (PUSCH). The components may include a CSI report for a plurality of transmission reception points. The UE may multiplex the UL-SCH data and the one or more components into the plurality of slots based at least in part on the schedule. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information indicating that demodulation reference signal (DMRS) time domain bundling is enabled. The UE may determine a time domain bundling configuration based at least in part on the information indicating that the DMRS time domain bundling is enabled. Accordingly, in some aspects, the UE may perform channel estimation based at least in part on DMRSs received in different physical downlink control channel monitoring occasions based at least in part on the time domain bundling configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink cancellation indication that identifies one or more first time-domain resources during which the UE is to refrain from transmitting at least a portion of a physical uplink shared channel (PUSCH) transmission scheduled to be transmitted during the one or more first time-domain resources. The UE may identify one or more second time-domain resources during which the UE is to transmit the at least the portion of the PUSCH transmission or another portion of the PUSCH transmission. The UE may transmit, based at least in part on receiving the uplink cancellation indication, the at least the portion of the PUSCH transmission or the other portion of the PUSCH transmission during the one or more second time-domain resources. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to an early indication, from a base station to a user equipment (UE), that may allow the UE to determine from the first symbol of a synchronization signal block (SSB) if the system information associated with the SSB is intended for the UE. Thus, when the UE receives the indication that the system information is dedicated to the UE, the UE may determine to receive and decode the remaining synchronization signal block, a master information block, a set of control resources, a downlink control channel, and a downlink shared channel to receive the system information. In some cases, the UE may determine that the system information is generic and end decoding during reception of the SSB to conserve computational resources by avoiding unnecessary decoding.

Abstract: A user equipment (UE) operating as an NR-Light UE may repeat transmissions of uplink signals such as a random access (RA) message (Msg) 3 on a physical uplink shared channel (PUSCH) during a random access channel (RACH) procedure. The UE may receive a random access response (RAR) message including a RAR uplink (UL) grant. The UE may determine, based on a single bit of the RAR message, whether repetition of a RA Msg 3 is indicated. The UE may determine both of a repetition factor and a transmit power control (TPC) command for the RA Msg 3 based on a TPC field of the RAR UL grant. The UE may transmit the RA Msg 3 based on the repetition factor and the TPC command.
