Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, downlink control information (DCI) associated with transmission configuration information, where the transmission configuration information includes a plurality of indicators of respective reference signals. The UE may communicate, with the base station, based at least in part on the transmission configuration information. The DCI may include a field associated with a transmission configuration indicator (TCI) state that includes the plurality of indicators. As an alternative, the DCI may include at least a first field associated with a first TCI state that includes a first indicator of the plurality of indicators and a second field associated with a second TCI state that includes a second indicator of the plurality of indicators. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described in which one of multiple transmission-reception points (TRPs) may be identified for beam failure procedures in a secondary cell (Scell). Reference signals of the different TRPs may have a different control resource set pool index values, and a user equipment (UE) may monitor such reference signals as part of a beam failure detection (BFD) procedure. The UE may identify one or more beams associated with a particular pool index value that has a degraded channel quality, and may determine to declare a beam failure. The UE may transmit a link recovery request to a serving cell that requests uplink resources for a beam failure recovery message. The UE may receive an uplink grant and may transmit a beam failure recovery message that indicates the Scell and TRP with the beam failure.

Abstract: Certain aspects of the present disclosure provide techniques for preconfiguring transmission configuration indication (TCI)-states at a user-equipment (UE) to reduce handover latency. Certain aspects provide a method for wireless communication. The method generally includes receiving, at a UE, a message indicating a first TCI-state for a current serving base station (BS) and a second TCI-state for a target BS, performing handover to the target BS, and activating the second TCI-state for the target BS after the handover.

Abstract: Aspects of the present disclosure provide various apparatuses and methods for extending a reference signal to facilitate carrier aggregation (CA). In some examples, a network includes a primary cell and one or more secondary cells that use a millimeter wave (mmW) carrier. When a UE is beyond the range of a reference signal from the secondary cell, the primary cell may trigger the secondary cell to increase the range of its reference signal using a higher gain beam and/or reference signal repetition.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may dynamically cancel and reschedule configured transmission occasions for communicating with a user equipment (UE). The transmission occasions may be configured according to a semi-persistent scheduling (SPS) configuration (e.g., for downlink transmissions) or a configured grant (CG) configuration (e.g., for uplink transmissions). The base station may transmit a dynamic grant to the UE that indicates a cancellation of a transmission occasion and schedules a dynamic transmission occasion for communicating data scheduled for transmission at the canceled transmission occasion. In some examples, the cancellation in the grant may be explicit or implicit.

Abstract: Control for multi-panel user equipment (MPUE) activation may be performed by both the MPUE and a base station. The MPUE may have at least a first panel and a second panel. The MPUE may send to the base station, a request to change an activation status of at least one panel of the MPUE. The base station may transmit a response indicating whether the request has been approved. The MPUE may change the activation status of the panel according to the response. Conversely, the MPUE may receive a command from the base station to change an activation status of at least one panel of the MPUE. The MPUE may determine whether to follow the command or override the command. The MPUE may transmit a response indicating whether the MPUEUE has followed the command or overridden the command.

Abstract: Methods, systems, and devices for wireless communications are described to provide for a user equipment (UE) and a base station to dynamically change a priority level of channel state information (CSI) reporting, such as from a low level to a high priority level, and in some cases back to the low level. If a condition is met, the UE and the base station may determine to change the priority of the CSI reporting from a low priority level to a high priority level. When the priority level for the CSI reporting is changed to a high priority level, the UE may transmit one or more CSI reports to the base station. The UE and the base station may change the priority level of the CSI reporting back to a low priority level if a second condition is met.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Abstract: A first apparatus may determine a first schedule associated with the one or more repetitions of the control information on the control channel based on the first information. The first apparatus may receive, from the network, at least one of the one or more repetitions of the control information on the control channel based on the first schedule, wherein the control information indicates a second schedule associated with a random access response (RAR) on a data channel. The first apparatus may receive, from the network, the RAR on the data channel based on the second schedule.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, to a base station, a request for a cell switch based at least in part on a trigger condition associated with an uplink-only cell switch being satisfied; and perform the uplink-only cell switch based at least in part on a physical-layer or medium-access-control layer inter-cell mobility operation with the base station based at least in part on transmitting the request. Numerous other aspects are provided.
