Abstract: A phase tracking reference signal (PT-RS) may be transmitted to enable a receiver to correct phase noise in wireless communication. A UE scheduled for one PDSCH with DMRS ports in two or more DMRS CDM groups that are associated with two TCI states may be configured for PT-RS using two PT-RS ports. Therefore, rather than limiting PT-RS to a single port, the PT-RS may be transmitted to the UE using two PT-RS ports. The apparatus transmits a capability indication for more than one PT-RS port for receiving a downlink shared channel based on a first TCI and a second TCI. The apparatus receives a configuration for a maximum number of downlink PT-RS ports from a base station.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station on a granting group common (GC)-physical downlink control channel (PDCCH), a multimedia broadcast multicast service (MBMS) downlink grant that schedules an MBMS transmission at each UE of a group of UEs that includes the UE. The method also includes receiving, from the base station on a triggering GC-PDCCH, a message indicating respective feedback resources for each UE of the group of UEs. The method further includes receiving, from the base station, the MBMS transmission. The method still further includes transmitting, to the base station via the feedback resources, a feedback report based on receiving the MBMS transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a physical downlink shared channel (PDSCH) transmission associated with a multi-PDSCH semi-persistent scheduling (SPS) that potentially conflicts with a second transmission in a slot. The UE may determine to keep at least one of the PDSCH transmission associated with the multi-PDSCH SPS or the second transmission in the slot based at least in part on one or more rules. The UE may perform, with a base station in the slot, at least one of the PDSCH transmission associated with the multi-PDSCH SPS or the second transmission that is kept based at least in part on the one or more rules. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive demodulation reference signals (DMRSs) in multiple physical downlink shared channel (PDSCH) reception occasions. The UE may perform joint channel estimation using the DMRSs in the multiple PDSCH reception occasions. The UE may transmit a feedback message after a processing time that includes an offset associated with the joint channel estimation, wherein the processing time starts after a last symbol of a PDSCH reception occasion of the multiple PDSCH reception occasions and ends before a first symbol of the feedback message. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support reference signal port association determination for single frequency network (SFN) uplink. For example, a user equipment may receive first control signaling scheduling transmission of sounding reference signals (SRS) from a plurality of SRS resource sets. The UE may receive second control signaling comprising an indication of one or more SRS resources from the plurality of SRS resource sets and scheduling transmission of one or more SFN uplink messages based at least in part on the indication of the one or more SRS resources. The UE may determine a frequency resource association between one or more phase tracking reference signal (PTRS) ports and one or more demodulation reference signal (DMRS) ports of a plurality of DMRS ports based at least in part on a port association rule and the indication of one or more SRS resources.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive (e.g., from a transmitting device) one or more control messages indicating a first physical resource block (PRB) bundling size for a first set of two or more layers of a downlink shared channel and a second PRB bundling size for a second set of two or more layers of the downlink shared channel. The receiving device may receive a downlink transmission (e.g., a downlink shared channel transmission) that includes multiple codewords, such as a first codeword corresponding to the first set of two or more layers and a second codeword corresponding to the second set of two or more layers. The receiving device may receive the downlink transmission and may decode each codeword based on one or more channel estimates using the first PRB bundling size and the second PRB bundling size.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques allow a user equipment (UE) to efficiently identify a trigger state that is linked to a configuration for receiving and measuring reference signals from a transmission and reception point (TRPs). The UE may receive an indication of different lists of trigger states associated with different TRPs, and, when the UE receives downlink control information (DCI) indicating a trigger state index, the UE may reference an appropriate list to identify the trigger state corresponding to the trigger state index. In particular, the UE may determine a control resource set (CORESET) pool index of a CORESET in which the DCI is received, and the UE may identify the trigger state corresponding to the trigger state index from a list of trigger states associated with the CORESET pool index.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with one or more semi-persistent scheduling (SPS) configurations. A base station may transmit a first downlink control information (DCI) transmission to the UE that activates an SPS configuration, and the first DCI may indicate a non-numeric feedback timeline for reporting associated acknowledgment feedback. The base station may transmit a subsequent second DCI transmission that provides feedback resources, and the UE may receive the second DCI and identify timing and resources for SPS acknowledgment feedback based on the second DCI. The UE may then transmit the acknowledgment feedback for one or more SPS transmissions in the feedback resources that are indicated by the second DCI transmission.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently monitoring for wake-up signaling from one or more transmission and reception points (TRPs), the wake-up signaling indicating the presence of data or control information in an on-duration state of a discontinuous reception (DRX) cycle. In particular, select TRPs may be used to transmit wake-up signaling to a user equipment (UE), and the UE may be configured to monitor for wake-up signaling from the select TRPs. Once the UE receives wake-up signaling prior to an on-duration state of a DRX cycle from any of the select TRPs, the UE may then determine the TRPs scheduled to transmit data or control information in the on-duration state (e.g., based on the WUS or based on further control signaling), and the UE may receive the data or control information from the TRPs in the on-duration state.
