Abstract: This disclosure provides methods, devices and systems for beamforming in wireless communications. Some implementations more specifically relate to beamforming configurations for multicast communications. A transmitting device may transmit multicast data to multiple receiving devices, concurrently, via a physical downlink shared channel (PDSCH). The PDSCH may be preceded by a physical downlink control channel (PDCCH). The PDCCH may provide scheduling information for the PDSCH, including a multicast beam associated with the PDSCH and a timing offset or delay between the PDCCH and the PDSCH. A receiving device may determine that the PDSCH contains multicast data based on an indication in the PDCCH. To receive the PDSCH, each receiving device may tune its antennas in a direction of the scheduled multicast beam or a default beam based on the delay between the PDCCH and the PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration of a set of synchronization signal blocks (SSBs) to be transmitted by a first base station or a second base station. In some cases, the UE may be served by the first base station and the UE may receive, from the first base station or the second base station, a message indicating that a transmission of at least one SSB of the set of SSBs is canceled and indicating resources for a signal (e.g., a reference signal, alternative SSB transmission) to be transmitted by the first base station or the second base station as an alternative to the canceled at least one SSB. The UE may receive, based on the received message from the first base station or the second base station, the signal using the indicated resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a tracking reference signal (TRS) pattern to be used for receiving a TRS. The TRS pattern may indicate a plurality of TRS symbols of the TRS, one or more TRS symbols of the plurality of TRS symbols having a bandwidth that is different than a bandwidth of at least one other TRS symbol of the plurality of TRS symbols, or having a discontinuous tone allocation. The UE may receive the TRS based at least in part on the TRS pattern. Numerous other aspects are provided.

Abstract: A UE configured to report resources, such as beams, to a base station may be unaware of the context or purpose for which the UE is reporting such resources. As different resources may provide different performance and/or quality when used in different contexts, the resources reported by the UE may provide lower quality and/or performance in one context relative to some other unreported resources. In order to improve resource reporting by the UE, the UE may be informed of an operational mode and/or a criteria based upon which the UE may select resources to report. The UE may report such selected resources to the base station in a group-based beam report. The base station may then configure communication with the UE based on the reported resources.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for using different configurations for downlink or uplink transmissions associated with different transmission configuration indication (TCI) states (e.g., transmitted on different beams). In one example, a base station may use different configurations for downlink transmissions to a user equipment (UE), and the base station may indicate the different configurations to the UE. For instance, the base station may transmit downlink control information (DCI) indicating a baseline configuration and other configurations as a delta of the baseline configuration. In another example, a base station may dynamically indicate a timing advance to a UE (e.g., in DCI or flow control feedback) for an uplink transmission from the UE associated with a TCI state, and the UE may use the dynamically indicated timing advance for uplink transmissions associated with the TCI state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information indicating a set of scheduling request (SR) occasions (SROs), wherein the configuration information identifies a set of mappings between the set of SROs and a set of synchronization signal blocks (SSBs); receive an SSB of the set of SSBs; and transmit one or more SRs on one or more selected SROs associated with the received SSB based at least in part on the set of mappings. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for signaling for configuring downlink transmissions are described. A user equipment (UE) may receive a configuration message from a base station indicating that a control resource set (CORESET) for a downlink control channel is associated with a set of transmission configuration indicator (TCI) states. The UE may subsequently receive a control message from the base station activating one or more of the TCI states. The UE may decode the downlink control channel based on the configuration message and the one or more activated TCI states. The UE may identify one or more TCI states (e.g., associated with the CORESET) to apply to a reception of a physical downlink shared channel (PDSCH) transmission. The UE may determine to apply one or more of the TCI states activated by the control message. The UE may determine to apply one or more different TCI states.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, on a downlink control channel and a first beam, first downlink control information (DCI), wherein the first DCI identifies a second DCI that is carried on a downlink shared channel; and receive multiple repetitions of the second DCI on the downlink shared channel on a plurality of second beams.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a priority rule for selecting to monitor a first beam associated with a first broadcast transmission or a second beam that differs from the first beam and is associated with a unicast transmission. The UE may use the priority rule when a scheduling conflict is identified between the first broadcast transmission and the unicast transmission. Such conflicts may include at least one of a broadcast transmission, a control resource set (CORESET) monitoring occasion of the broadcast transmission, or reference signals of the broadcast transmission at least partially overlapping with a unicast transmission, a CORESET monitoring occasion of the unicast transmission, or reference signals associated with the unicast transmission. The UE may monitor, in accordance with the priority rule, one of the first beam or the second beam based on identification of scheduling conflict.
