Abstract: Certain aspects of the present disclosure provide techniques for communicating using a target transmission configuration indicator (TCI) state associated with a dynamically received target TCI prior to transmitting an acknowledgement for the target TCI. An example method performed by a user equipment (UE) includes receiving a target transmission configuration indicator associated with a target transmission configuration indicator state and one or more target channels and communicating one or more transmissions via a first target channel of the one or more target channels prior to transmitting signaling acknowledging the target transmission configuration indicator. Based on whether at least one criterion is satisfied or not, the UE may either use the target transmission configuration indicator state or a default transmission configuration indicator state when communicating the one or more transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station using UE cooperation. For example, a first UE may transmit an uplink signal indicating a request for the base station to transmit a UE discovery request signal to a second UE. In response to transmitting the uplink signal, the first UE may receive a sidelink signal from the second UE. The sidelink signal may indicate that the second UE may be available for a cooperative link with the first UE. In some cases, based on the sidelink signal, the first UE may establish the cooperative link with the second UE. In some examples, based on establishing the cooperative link, the first UE may receive downlink communications from the base station via at least sidelink communications from the second UE over the cooperative link.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support user equipment (UE) cooperation. When a first UE and second UE are in a cooperative configuration, a base station may use the first UE to request and obtain channel information for the second UE. For example, the base station may transmit a request for channel information to the first UE and the first UE may relay the request to the second UE. The second UE may determine the channel information and transmit a report including the channel information to the first UE, where the first UE may relay the report to the base station. In some examples, the report, the request, or both may be exchanged between devices using medium access control control element (MAC-CE)-based methods or using downlink control information (DCI)-based methods. The DCI-based methods may involve relaxed timings.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network entity, a transmit receive point (TRP)-specific beam failure recovery (BFR) medium access control control element (MAC-CE) indicating a new beam for the UE based at least in part on a TRP with beam failure. The UE may receive, from the network entity, a TRP-specific BFR response based at least in part on the TRP-specific BFR MAC-CE. The UE may determine a subcarrier spacing (SCS) for a TRP-specific BFR beam resetting timing based at least in part on an SCS associated with the TRP-specific BFR response being different than an SCS associated with the TRP with beam failure. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first user equipment (UE) may receive an active communication configuration between the first UE and a base station. The first UE may receive a UE cooperation configuration between at least the first UE and a second UE. The UE cooperation configuration may include a configuration for communicating messages between the base station and a set of antenna panels corresponding to at least the first UE and the second UE as a single entity. The UE cooperation configuration may include parameters associated with the second UE. The first UE may identify, from the set of antenna panels, an antenna panel for reception of a downlink message based on the UE cooperation configuration. The first UE may transmit a message to the base station, the second UE, or both in response to the downlink message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a first slot, a downlink control information (DCI) transmission that indicates a unified transmission configuration indicator (TCI), wherein the DCI transmission does not include a downlink assignment. The UE may transmit hybrid automatic repeat request (HARQ) feedback corresponding to the unified TCI, wherein the HARQ feedback comprises an acknowledgment to indicate successful reception of the unified TCI in the DCI transmission or a negative acknowledgement to indicate a failed reception of the unified TCI in the DCI transmission. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit, to a base station, a capability report that includes an indication of a maximum number of reference signal resources within a transmission time interval (TTI) for which the UE supports channel state information (CSI) reporting. The maximum number of reference signal resources may be based on a capability for supporting joint CSI reporting for both a downlink and an uplink. The UE may receive, from the base station, a report configuration in response to the capability report. Subsequently, the base station may transmit reference signals to the UE, which the UE may use to determine CSI for both the downlink and the uplink. The UE may then transmit, to the base station, a CSI report including the CSI for both the downlink and the uplink, in accordance with the report configuration.

Abstract: Certain aspects of the present disclosure provide techniques for systems and methods for detecting trigger conditions for panel specific power reporting. For example, a user equipment (UE) may detect that a trigger condition for panel specific power reporting is met, where the trigger condition involves at least one metric for at least one of multiple antenna panels of the UE. Further, the UE may transmit a report with power-related information specific for at least one of the antenna panels in response to detecting the trigger condition.
