Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) and indicating a physical uplink control channel (PUCCH) repetition factor. The UE may transmit, and the base station may receive, a PUCCH that includes hybrid automatic repeat request acknowledgement feedback associated with the PDSCH. In some aspects, one or more instances of the PUCCH are transmitted across one or more uplink slots or sub-slots based at least in part on the PUCCH repetition factor indicated in the DCI. Numerous other aspects are provided.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink control information (UCI) payload satisfies a threshold size condition. The UE may map the UCI payload to an uplink control sequence. The UE may transmit a physical uplink control channel (PUCCH) that include the uplink control sequence to a base station. The uplink control sequence may be representative of the UCI payload. The base station may receive the PUCCH that includes the uplink control sequence from the UE. The base station may also determine the UCI payload by associating the uplink control sequence with a corresponding sequence index of the one or more sets of uplink control sequences.

Abstract: Wireless communications systems and methods related to negative acknowledgement (NACK)-triggered sounding reference signal transmissions are provided. In some aspects, a user equipment may detect an error when decoding a data transmission received from a base station via a bandwidth part. The UE may then trigger, in response to detecting the error, a transmission to the BS of a first sounding resource signal using a first SRS resource set of the bandwidth part.

Abstract: Aspects relate to radio link management for a first type of link that is a high reliability, low-latency communication link such as ultra-reliable, low-latency communication (URLLC). Radio link failure (RLF) of the link may be determined in a wireless device that then transmits a link recovery request (LRR) communicating the RLF and a request for link recovery to a network in a reserved resource in an uplink channel using a second type of link that does not have as high priority (e.g., not as high reliability or as low-latency) as the first type of link, such as enhanced mobile broadband (eMBB). The wireless device receives a grant of uplink resources from the network responsive to the LRR, where the uplink resources are used by the wireless device to transmit an RLF report to the network and are also of the second type of link.

Abstract: Techniques related to multi-layer wireless communications are disclosed. Some aspects of the disclosure relate to devices and methods for determining a transmission power boost for a phase-tracking reference signal (PT-RS). A wireless user equipment (UE) may map a multi-layer uplink transmission to a plurality of PT-RS ports by distributing the layers of the multi-layer uplink transmission among the plurality of PT-RS ports. The UE may determine a first transmission power boost for a first PT-RS port, and a second transmission power boost, different from the first transmission power boost, for a second PT-RS port. The UE may transmit a first PT-RS corresponding to the first PT-RS port utilizing the first transmission power boost, and the second PT-RS corresponding to the second PT-RS port, frequency division multiplexed with the first PT-RS, utilizing the second transmission power boost. Other aspects, embodiments, and features are also claimed and described.

Abstract: In wireless communication systems using a subband full duplex carrier, a single slot may include one or more uplink (UL) portions and/or one or more downlink (DL) portions. In a case where a scheduler operating in a 3GPP New Radio (NR) network utilizes a Type 0 or Type 1 resource allocation, part of the DL allocation may fall within the UL portion of the carrier designated by the slot format, or vice versa. User equipment (a UE) may perform a logical operation that identifies, as a usable downlink resource allocation, a set of resource blocks belonging to both a given UL/DL resource allocation and a set of resources designated for UL/DL transmission in the slot format.
