Abstract: A base station performs joint channel estimation for a set of physical uplink control channels (PUCCHs), where one or more PUCCHs of the set of PUCCHs comprises a corresponding DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUCCHs, one or more PUCCHs of the set of PUCCHs comprising a DMRS from the base station. The base station transmits, and the UE receives, spatial filter or power control information elements for each PUCCH of the set of PUCCHs. The UE transmits the PUCCHs comprising corresponding DMRS based on a same spatial filter with a same power control parameters, spatial filter or power control information element for a first PUCCH of the set of PUCCHs indicating the same spatial filter or same power control parameter, the set of PUCCHs having phase continuity.

Abstract: A UE may receive a configuration of multiple TCI states including a TCI state for each of multiple TRPs. The UE may also receive an indication of dormancy for one or more TRP of the multiple TRPs. The UE may further transmit or receive communication based on a default TCI state, the default TCI based at least in part on the dormancy of the TRP. The UE may communicate with a network entity that configures multiple TCI states for the UE. The multiple TCI states may include a TCI state for each of multiple TRPs. The network entity may output for transmission an indication of dormancy for one or more TRP of the multiple TRPs. The network entity may further output or obtain communication based on a default TCI state, the default TCI based at least in part on the dormancy of the TRP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a network entity scheduling a set of multiple periodic tracking reference signals (TRSs) and indicating a transmission power level for the periodic TRSs. For example, the control signaling may be received via radio resource control (RRC). The UE may receive a downlink control information (DCI) message from the network entity indicating an adjustment to the transmission power level and a resource for an aperiodic TRS. The UE may monitor the resource for the aperiodic TRS in accordance with the indicated adjustment to the transmission power level. The UE may transmit a message to the network entity indicating a measurement of the aperiodic TRS based on the adjustment to the power level. The adjustment to the power level may apply to one or more of the set of multiple periodic TRSs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a capability associated with maintaining phase continuity and power consistency for demodulation reference signal (DMRS) bundling between a full-duplex slot and a half-duplex slot. The UE may transmit a first signal during a first slot of a first time domain window (TDW) associated with the DMRS bundling. The UE may determine whether to terminate the first TDW based on the capability associated with maintaining the phase continuity and the power consistency between the full-duplex slot and the half-duplex slot. The UE may transmit a second signal during a second slot of the first TDW or a second TDW based on the determination of whether to terminate the first TDW.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive, from a base station, an indication of a time domain resource allocation, wherein the indication is associated with a starting symbol and a length and includes symbols across at least two slots. Accordingly, the mobile station may communicate, with the base station, using the time domain resource allocation. In some aspects, a mobile station may receive, from a base station, an indication of at least two slots to be merged, wherein the at least two slots are associated with a periodicity. Accordingly, the mobile station may communicate, with the base station and within the at least two slots. Numerous other aspects are provided.

Abstract: Aspects relate to wireless communication including the provision of the ability of a user equipment (UE) to indicate the capability of the UE for demodulation reference signal (DMRS) bundling and/or joint channel estimation (JCE). In aspects, the capability indication includes using at least a physical random access channel (PRACH) to indicate the capability of a UE for repeated transmission of the physical uplink shared channel (PUSCH) carrying a connection message, and counting of available slots that are used for the repeated transmission of the physical channel. Additionally, the UE may be configured to indicate the capability for JCE through a demodulation reference signal (DMRS) configuration or a DMRS port.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may dynamically and reliably indicate that pending transmissions are part of a full duplex operation via downlink control information (DCI) designs described herein. For example, a base station may transmit, to a user equipment (UE) a DCI including no more than one downlink grant and no more than one uplink grant for a full duplex operation. In some examples, the base station may transmit a first-stage DCI including partial information, and second-stage DCIs including full uplink and downlink grants for a full duplex operation. In some examples, the base station may configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and may dynamically indicate, to the UE, whether the overlapping uplink and downlink resources are scheduled for a full duplex operation.
