Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message configuring the UE to communicate coordinated transmissions with multiple transmission reception points (TRPs) using a first coordinated transmission mode of a set of different coordinated transmission modes. The UE may receive, based on the configuration message, downlink control information including at least one indicator and receive a first coordinated transmission communicated in accordance with the first coordinated transmission mode. The UE may transmit, in accordance with a feedback configuration corresponding to the at least one indicator and the first coordinated transmission mode, a feedback message for the first coordinated transmission to at least one of the multiple TRPs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect an out-of-coverage scenario based at least in part on determining that a synchronization source associated with a wireless network is unavailable or has a signal strength that fails to satisfy a threshold. The UE may transmit, on a sidelink channel, a sidelink synchronization signal in a transmission period that includes a plurality of synchronization signal occasions based at least in part on the out-of-coverage scenario. In some aspects, the UE may transmit the sidelink synchronization signal according to a reduced duty cycle that causes the sidelink synchronization signal to be transmitted during fewer than all of the plurality of synchronization signal occasions. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of whether the UE is capable of using a virtual port to transmit uplink communications using a maximum transmit power according to a power class of the UE. The virtual port may be a combination of one or more antenna ports. The indication may be based at least in part on an operating mode of the UE. The UE may receive, from the base station, a sounding reference signal configuration based at least in part on the indication. Numerous other aspects are provided.

Abstract: A method, at a transmission/reception point (TRP), of producing a positioning reference signal muting pattern includes: obtaining, at the TRP, one or more positioning reference signal criteria, the one or more positioning reference signal criteria regarding at least one of positioning reference signal transmission or positioning reference signal reception; and producing, at the TRP, the positioning reference signal muting pattern such that the positioning reference signal muting pattern meets the one or more positioning reference signal criteria

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sounding reference signal (SRS) on a plurality of antenna ports. The UE may transmit the SRS on one or more virtual antenna ports, the one or more virtual antenna ports being based at least in part on the plurality of antenna ports. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more time slots in which a first communication on a multi-slot physical uplink control channel (PUCCH) overlaps with a second communication on another PUCCH. The UE may transmit, for each time slot of the one or more time slots, the first communication or the second communication based at least in part on a first priority assigned to the multi-slot PUCCH and a second priority assigned to the other PUCCH. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for scaling transmission power across transmit chains for physical uplink shared channel (PUSCH) transmissions. In some cases, a UE may determine a transmit power budget, receiving signaling indicating how to allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, and transmitting the PUSCH using the transmit chains according to the determined transmit power allocation.

Abstract: Some examples of the techniques described herein may provide approaches for scheduling a sounding reference signal (SRS) in a time-division duplex (TDD) structure with one or more mixed sub-band full-duplex (SBFD) slots. For SRS based on physical slot counting, for example, some of the techniques described herein may provide approaches indicating whether to transmit or drop SRS resources in SBFD or non-SBFD symbols in a mixed SBFD slot. For SRS based on available slot counting, for example, some of the techniques described herein may indicate whether a mixed SBFD slot is an available slot for SRS transmission. For duplex-specific SRS, for example, some of the techniques described herein may indicate whether to label or determine a mixed SBFD slot as an SBFD-specific slot or non-SBFD-specific slot, or whether a resource in a mixed SBFD slot may be sent or dropped.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may map uplink control information (UCI) bits and uplink shared channel (UL-SCH) data bits to a first subset of resources associated with a physical uplink shared channel (PUSCH). The UE may copy symbols associated with the UCI bits and the UL-SCH data bits from the first subset of resources to one or more remaining subsets of resources. The UE may apply an orthogonal cover code (OCC) across a plurality of subsets of resources, including the first subset of resources and the one or more remaining subsets of resources, associated with the PUSCH. The UE may transmit, based at least in part on the OCC applied across the plurality of subsets of resources, multiplexed UCI bits and UL-SCH data bits. Numerous other aspects are described.
