Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may monitor for transmissions during an on-duration of a discontinuous reception cycle. The UE may receive one or more go-to-sleep indications from one or more transmission/reception points (TRPs), and may discontinue monitoring for transmissions from one or more of the TRPs responsive to the one or more go-to-sleep indications. Each TRP of the two or more TRPs may transmit a separate per-TRP go-to-sleep signal that indicates that the TRP will not transmit during a time period associated the go-to-sleep signal. In other cases, a TRP may transmit a cross-TRP go-to-sleep signal that has go-to-sleep indications for multiple TRPs.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a base station or a user equipment, may identify an energy detection threshold for a sensing beam associated with a channel access procedure, such as a listen-before-talk (LBT) procedure. The wireless device may also identify a set of transmit power parameters for one or more transmit beams. The wireless device may determine a degree of overlap between a coverage area of one or more transmit beams and a coverage area of the sensing beam. The wireless device may adjust the set of transmit power parameters, the energy detection threshold, or a combination thereof based on the degree of overlap. The wireless device may perform the channel access procedure based on the determining, the adjusting, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, in a control channel, a first grant identifying a first set of resources of a first data channel on which the UE is to monitor for one or more second grants, the first data channel being downlink. The UE may monitor the first set of resources in the first data channel for the one or more second grants, the one or more second grants identifying a second set of resources of a second data channel on which the UE is to perform data communications. The UE may transmit, based at least in part on the monitoring the first set of resources, a feedback message associated with receipt of the one or more second grants.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes a method for wireless communications at a base station. The method includes transmitting a message to a number of user equipments (UEs) over a single frequency network channel using a first beam sweep pattern. The method also includes identifying a second beam sweep pattern from a plurality of beam sweep patterns that is different from the first beam sweep pattern for retransmissions of the message. The method further includes transmitting a retransmission of the message to the plurality of UEs over the single frequency network channel using the second beam sweep pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a multiple listen-before-talk (LBT) bandwidths, where each LBT bandwidth is associated with one or more downlink control channel candidates of a search space for a control resource set. The UE may monitor the LBT bandwidths during a wakeup signal period for a wakeup signal from the base station. The UE may be configured with a total number of blind hypotheses in the set of blind hypotheses which is equal to or greater than a total number of LBT bandwidths. The UE may determine whether to wake up and monitor an on duration of a discontinuous reception cycle based on detection of the wakeup signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first downlink control information (DCI) communication for scheduling a first physical downlink shared channel (PDSCH). The first PDSCH may be associated with at least a first transmit receive point (TRP). The UE may receive a second DCI communication for scheduling a second PDSCH. The second PDSCH may be associated with a second TRP and at least one of the first TRP or a third TRP. The UE may receive downlink communications based at least in part on the first DCI communication and the second DCI communication. Numerous other aspects are provided.

Abstract: Techniques are described for selecting transmit beam sets in multi-stream environments as part of beam selection procedures. The selection procedures and the reporting procedures of the beam selection procedures may include reporting information about potential sources of interference for the selected transmit beams. A base station may transmit reference signals to a user equipment (UE) as part of a beam sweep of directional beams. The UE may measure signal quality parameters associated with the reference signals and may select a plurality of transmit beam set candidates based on the signal quality parameters. The UE may report to the base station information related to inter-beam interference in multi-stream environments. The base station may determine which transmit beams to use to transmit information to the UE based on the report received from the UE that include information about inter-beam interference.
