The apparatus can select one or more rows or one or more columns in a DFT matrix, the one or more rows being even-numbered rows in the DFT matrix and the one or more columns being even-numbered columns in the DFT matrix. The apparatus can also determine an orthogonal matrix based on the one or more rows or the one or more columns in the DFT matrix, the orthogonal matrix having a size of (M×N)×(M×N) with M×N rows and M×N columns. Also, the apparatus can determine a codebook based on the orthogonal matrix, the codebook including a plurality of codepoints. The apparatus can also transmit at least one signal including a first codepoint of the plurality of codepoints in the codebook.

Abstract: Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.

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 identify a collision between a first uplink transmission and a second uplink transmission, wherein the first uplink transmission is a high priority uplink transmission and the second uplink transmission is a low priority uplink transmission; and cancel the second uplink transmission during a defined time period, wherein the defined time period has an end point based at least in part on a processing time and an offset, and a start point based at least in part on a triggering event for the first uplink transmission or a UE capability. 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 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: The present disclosure provides techniques configuring channel state information (CSI) reporting for certain service types, such as the ultra-reliable low latency communications (URLLC) service type. In some cases, a UE may obtain information regarding a first set of channel state information (CSI) reporting configurations for a first service type separate from a second set of CSI reporting configurations for a second service type, receive a first downlink control information (DCI) scheduling a CSI report for the first service type on at least one physical uplink shared channel (PUSCH), generate at least one CSI report for the first service type based on one of the first set of CSI reporting configurations selected based on a field in the DCI, and transmitting the CSI report for the first service type on the PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple channel state information (CSI) reports scheduled to be transmitted in a slot on respective physical uplink control channel (PUCCH) resources. For example, the multiple CSI reports may include one or more CSI reports associated with a first service type and one or more CSI reports associated with a second service type. The UE may select, from the multiple CSI reports, one or more CSI reports to be transmitted in the slot based at least in part on a first priority associated with the first service type and a second priority associated with the second service type. Accordingly, the UE may transmit, in the slot, one or more PUCCH transmissions that include the one or more selected CSI reports. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment determine that a physical uplink shared channel (PUSCH) communication, scheduled by an uplink grant, and a physical uplink control channel (PUCCH) communication, corresponding to a physical downlink shared channel (PDSCH) communication scheduled by a downlink grant, are scheduled to overlap in one or more symbols; determine a threshold time based at least in part on an earliest scheduled starting time of the PUSCH communication or the PUCCH communication; selectively multiplex the PUSCH communication and the PUCCH communication based at least in part on whether the uplink grant, the downlink grant, and the PDSCH communication are received before the threshold time; and transmit the PUSCH communication, the PUCCH communication, or both the PUSCH communication and the PUCCH communication based at least in part on the selective multiplexing.
