Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.

Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a user equipment (UE) utilizing beam sweeping during a random access procedure to determine an uplink beam for subsequent communication with a base station. The UE may transmit a first message indicating a random access preamble for a random access procedure and a plurality of reference signals using a set of directional beams. The base station may receive the reference signals or information related to the reference signals and transmit a second message indicating a directional beam of the set of directional beams and a set of resources. Upon receiving the second message, the UE may transmit the third message over the set of resources using the indicated directional beam.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may receive a downlink control information (DCI) on a physical downlink control channel (PDCCH). The DCI may include one or more of an indication of a set of transmission configuration indicator (TCI) states related to a physical downlink shared channel (PDSCH), one or more receive beams associated with the set of TCI states, or a physical downlink shared channel (PDSCH) scheme. The UE may decode the DCI and may determine a temporal period associated with the indication of the set of TCI states. The UE may receive, based on the temporal period, the PDSCH according to one or more of the set of TCI states, the one or more receive beams associated with the set of TCI states, the PDSCH scheme, or one or more default receive beams.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARM) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive signaling scheduling a first set repetitions of a first uplink shared channel transmission associated with a first sounding reference signal (SRS) resource set and a second set of repetitions of a second uplink shared channel transmission associated with a second SRS resource set. The UE may receive a request to transmit one or more channel state information (CSI) reports and an indication that the CSI reports are to be multiplexed with one of the first set of repetitions or the second set of repetitions or with both of the first and second set of repetitions. The UE may then transmit the CSI reports in accordance with the indication by multiplexing the CSI reports with one or both of the first set of repetitions and the second set of repetitions.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for handling hybrid automatic repeat request (HARQ) processes with discontinuous reception (DRX) operations. A user equipment (UE) may use timers to maintain an ON duration in DRX. The UE may receive, via downlink control information (DCI), an indication of a feedback transmission opportunity (TxOP) for a HARQ process. The UE may activate a timer at the end of the TxOP regardless of whether the UE transmits feedback in the TxOP to ensure that the UE remains active. In some implementations, a base station may provide the UE with multiple opportunities to transmit a feedback message. The UE may reactivate a timer after each feedback TxOP for the same HARQ process or may activate the timer after the first feedback TxOP and may refrain from activating the timer after subsequent feedback TxOPs for the HARQ process.
