The network entity may transmit, to the UE, a cancellation indication Feedback Message that cancels a scheduled uplink transmission in which the UE is scheduled to provide feedback data corresponding to a subset of the set of feedback process identifiers. The network entity may transmit, to the UE, a control message scheduling the UE to transmit the feedback data corresponding to the subset of the set of feedback process identifiers (e.g., based on the cancellation indication). The UE may transmit, to the network entity, a feedback message including the feedback data for the subset based on the control message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling scheduling a physical uplink control channel (PUCCH) transmission and a physical uplink shared channel (PUSCH) transmission that overlap in the time domain. The UE may simultaneously transmit the PUSCH and PUCCH transmissions if the scheduled quantity of layers for the PUSCH transmission (or the scheduled quantity of layers for the PUSCH transmission and the PUCCH transmission) does not exceed an indicated maximum quantity of layers for PUSCH transmissions (or PUSCH and PUCCH transmissions). For a codebook based PUSCH transmission, the UE may simultaneously transmit the PUSCH and PUCCH transmissions if the scheduled quantity of antenna ports for the PUSCH transmission (or the scheduled quantity of antenna ports for the PUSCH transmission and the PUCCH transmission) does not exceed an indicated maximum quantity of ports for PUSCH transmissions (or PUSCH and PUCCH transmissions).

For example, the UE may receive a first control message indicating a set of first PUSCH messages associated with a first rank value and a first quantity of ports and a second control message indicating a second PUSCH message associated with a second rank value and a second quantity of ports. In cases that transmitting both the first and second PUSCH messages exceeds a threshold rank value or a threshold quantity of ports, the UE may refrain from transmitting one of the first or second PUSCH messages.

Abstract: This disclosure provides systems, methods and apparatuses for uplink channel transmission for multiple transmit receive points (TRPs).

Abstract: Certain aspects of the present disclosure provide techniques for quasi-colocation (QCL) assumption for an aperiodic channel state information (A-CSI) reference signal (RS) configured with multiple transmission reception point (mTRP). A user equipment (UE) may receive signaling configuring the UE with a plurality of index values associated with different control resource sets (CORESETS). The UE may receive, from a base station (BS), first downlink control information (DCI) triggering an A-CSI-RS resource set for A-CSI reporting. The first DCI is received in a first CORESET of the different CORESETs associated with a first index value of the plurality of index values. The UE may determine a first time offset between the first DCI and the A-CSI-RS resource set. When the first time offset is smaller than a threshold time offset, the UE may determine a QCL assumption for receiving the A-CSI-RS based, at least in part, on the first index value.

The method comprises receiving, from a network entity, downlink control information (DCI) for a downlink transmission, wherein the downlink transmission is based on a rate-splitting multiple access scheme, and wherein the downlink transmission comprises a common stream, a demodulation reference signal (DM-RS) for the common stream, a private stream and a DM-RS for the private stream, determining, based on the DCI, a DM-RS configuration for the DM-RS for the common stream and for the DM-RS for the private stream, and receiving, based on the DM-RS configuration, the downlink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARM) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: Methods, systems, and devices for wireless communications are described. A network node may transmit a control message to one or more user equipment (UEs) that identifies that multi-user multiple input multiple output (MU-MIMO) signals from the network node include one or more private messages for a UE and one or more common messages for a UE and at least one other UE. The network node may transmit an additional control message that identifies a first phase tracking reference signal (PTRS) port for the one or more private messages and a second PTRS port for the one or more common messages, where the PTRS ports may be the same or different. Then, the network node may transmit the private messages using the first PTRS port and the common messages using the second PTRS port.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) may receive an indication of a set of channel measurement resources (CMRs) that are configured for a group-based reference signal measurement for multiple transmission and reception points (TRPs). The UE may identify or determine whether a set of one or more directional beams used by the UE to measure reference signal transmissions from each of the multiple TRPs satisfy a threshold directivity gain. The UE may transmit a request to enable a scheduling restriction at the UE for a time period associated with the group-based reference signal measurement if the set of directional beams fail to satisfy the threshold directivity gain and may transmit a request to disable the scheduling restriction if the set of directional beams satisfy the threshold directivity gain.

Abstract: Aspects of this disclosure provide methods, devices and systems for concurrently transmitting control information and data information. In some more specific aspects, a base station may transmit one or more parameters to a user equipment (UE) that indicate to the UE to refrain from transmitting uplink control information together with uplink data information in an uplink data channel. Instead, the one or more parameters may configure the UE to transmit the uplink control information and the uplink data information using overlapping resources in different channels. In some more specific aspects, the UE may transmit the uplink control information in a slot of an uplink control channel and transmit the uplink data information in a slot of the uplink data channel that at least partially overlaps with the slot of the uplink control channel.

Abstract: Techniques for signaling uplink transmission configuration indicator (TCI) states are disclosed. In an example, a base station may determine one or more capabilities of a user equipment (UE). The base station may also determine one or more uplink TCI states for the UE to use based on the one or more capabilities. The base station may also transmit, to the UE, signaling of the one or more uplink TCI states.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, downlink control information (DCI) that activates periodic channel state information (CSI) reporting via uplink shared channel transmissions (e.g., via physical uplink shared channel (PUSCH) transmissions). The UE may then identify a trigger condition that triggers a transmission of both a first instance of a CSI report and a second instance of the CSI report within a period of the periodic CSI reporting. Based on the satisfaction of the trigger condition, the UE may transmit the first instance of the CSI report via a first uplink shared channel transmission and the second instance of the CSI report via a second uplink shared channel transmission, where both uplink channel transmissions are within the period of the periodic CSI reporting.
