    Abstract: Methods, systems, and devices for wireless communications are described that support group-based acknowledgment feedback techniques. Two or more different groups of downlink transmissions may each have an associated group-based acknowledgment feedback, and a base station may transmit downlink control information to a UE that indicates one or more parameters that are used to determine which downlink transmissions are to be reported in the group-based feedback. Based on the parameters in the downlink control information, the UE may determine the feedback to be reported, and a timing for when to transmit the feedback to the base station.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit, to a user equipment (UE) for a beam sweeping procedure, at least one downlink control channel associated with at least one beam. The BS may receive, based at least in part on transmitting the at least one downlink control channel, feedback information relating to the at least one downlink control channel. The UE may receive at least one downlink control channel associated with at least one beam. The UE may transmit feedback information relating to the at least one downlink control channel. 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 demodulation reference signal (DMRS) information that indicates a first DMRS configuration for a first transmit receive point (TRP) and a second DMRS configuration for a second TRP; generate a first DMRS-based channel quality report, based at least in part on a first set of DMRS received from the first TRP according to the first DMRS configuration, and a second DMRS-based channel quality report based at least in part on a second set of DMRS received from the second TRP according to the second DMRS configuration; and transmit the first DMRS-based channel quality report and the second DMRS-based channel quality report. Numerous other aspects are provided.

    Abstract: Wireless communications systems and methods related to applying variable cyclic prefix (CP) lengths to symbols within a transmission period in a wireless network are provided. A first wireless communication device identifies a first cyclic prefix (CP) configuration for a transmission period. The first wireless communication device communicates, with a second wireless communication device during the transmission period, a first communication signal including a first plurality of symbols, wherein each of the first plurality of symbols include an individually configurable CP length configured based on the first CP configuration. A first symbol of the first plurality of symbols includes a first CP length. A second symbol of the first plurality of symbols includes a second CP length that is longer than the first CP length.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a transmission beam configuration for transmitting multicast data to a user equipment (UE) in a joint transmission using a set of transmission/reception points (TRPs) based on outcomes of listen before talk (LBT) procedures performed at the TRPs. In some examples, the base station may indicate to the UE that the UE is to determine a UE beam configuration and a quasi co-location (QCL) relationship associated with the TRPs for receiving the multicast data based on signaling from the TRPs. In some examples, the base station may transmit multicast data from a first TRP (e.g., a serving cell) during a first transmission opportunity (TxOP), and the UE may determine the QCL relationship for the set of TRPs. During a second TxOP, the base station may transmit multicast data in a joint transmission from the set of TRPs.

    Abstract: Methods, systems, and devices for wireless communications are described to support transmission of a resource modification information request from a user equipment (UE) to a base station, where the resource modification request may request an increased density of uplink transmission occasions. For example, the resource modification request may request an increase from a first density of uplink transmission occasions configured for the UE. The resource modification request may include a request for a decreased periodicity of uplink transmission occasions, an increased number of groups of repetitions for uplink transmission occasions, an increased number of resource blocks for uplink transmission occasions, or an increased modulation coding scheme for uplink transmission occasions. The base station may receive the resource modification request and may transmit a message to the UE, which may indicate a modified or new uplink grant configuration for uplink transmission occasions having a higher density (e.g., a second density).

    Abstract: Methods, systems, and devices for wireless communications are described. A device such as a user equipment (UE) or a base station may identify a beam switching capability of the UE, the beam switching capability indicating a threshold quantity of beam switches during a transmission time interval, a threshold quantity of symbol periods between beam switching operations, or a combination thereof. The device may determine that the beam switching capability of the UE is satisfied based at least in part on one or more parameters (e.g., one or more symbol period durations, one or more quantities of beam switches during a transmission time interval, one or more adjustment parameters, one or more threshold values associated with the capability of the UE, etc.). The device may perform one or more beam switching operations based on determining that the beam switching capability is satisfied.

    Abstract: Methods, systems, and devices for wireless communications are described for prioritization of sidelink communications of a user equipment (UE) with one or more access link communications. A prioritization scheme may provide inter-UE and intra-UE prioritization that may be used to prioritize sidelink communications and one or more access link communications. Inter-UE prioritization may be used at the UE to determine whether to cancel all or a portion of a sidelink communication that uses resources indicated in a cancellation indication from a base station, or to transmit the sidelink communication irrespective of the cancellation indication. Intra-UE prioritization may be used at the UE to determine which of one or more access link communications or a sidelink communication is to be maintained or canceled in the event of overlapping resources between the access link and sidelink communications.
