Abstract: Aspects are provided which allow a UE to provide a CSI report including an expiration time to a base station to reduce the risk of improper scheduling decisions at the base station based on outdated CSI reports. The UE obtains a channel measurement signal from the base station. The UE identifies CSI based on the channel measurement signal and provides a CSI report to the base station including the CSI. The CSI report further includes an expiration time for the CSI report. The base station obtains the CSI report from the UE including the expiration time for the CSI report, and the base station processes downlink data for transmission based on the expiration time in the CSI report.

Abstract: Aspects described herein relate to receiving, from a base station, an uplink resource grant for transmitting uplink control information, where the uplink resource grant indicates an uplink control information format, bundling a number of instances of feedback in a number of feedback bits, where the number of feedback bits corresponds to the uplink control information format, and where the number of instances of feedback correspond to SPS downlink communications, and transmitting, to the base station and in the uplink control information, the number of feedback bits. Other aspects relate to transmitting the uplink resource grant, and receiving uplink control information based on the indicated uplink control information format.

Abstract: Aspects are provided which allow for multiplexing of higher priority uplink transmissions with lower priority uplink transmissions while maintaining URLLC of the higher priority uplink transmission. A UE receives from a base station information including resources for first and second uplink data, where at least a portion of the resources for the first and second uplink data overlap in time. The first and second uplink data are associated with different priority levels. The UE determines whether to multiplex the uplink data based on a transmission timing difference between a scheduled transmission time and a multiplexed transmission time for the second uplink data on the respective resources. The base station makes a similar determination. If the transmission timing difference fails to meet a delay threshold, multiplexing is performed; otherwise, the lower priority transmission is dropped. Thus, different priority multiplexing may occur in low latency situations, satisfying URLLC.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for configuring group indices for uplink transmissions from a user equipment (UE) such that the UE may be able to determine whether to combine uplink transmissions scheduled on overlapping time resources. Specifically, the UE may combine uplink transmissions associated with a same group index for transmission in a single channel, and the UE may avoid combining uplink transmissions associated with different group indices. In some cases, the indication of a group index associated with an uplink transmission from a UE may be explicit (e.g., provided in a downlink control information (DCI) message), and, in other cases, the indication of a group index associated with an uplink transmission from a UE may be implicit (e.g., corresponding to a resource allocated for the uplink transmission).

Abstract: A UE may identify slots to transmit and/or receive information related to one or more HARQ processes in frame structure that includes both sub-band full duplex slot types and time division duplex slot types. Based on a first slot used for control information, a UE can identify a second slot for PUSCH or PDSCH communication based on an offset between the first slot and the second determined by calculating slot offsets (e.g., based on parameters received from a base station). In some aspects, a UE may exclude certain slot duplex types (e.g., SBFD or TDD) when calculating slot offsets. In some aspects, a UE may calculate slot offsets differently for different HARQ processes corresponding to one frame. In some aspects, slot offset behaviors may be based on priority of information associated with a HARQ process.

Abstract: Apparatus, methods, and computer-readable media for facilitating signaling of PUCCH and PUSCH simultaneous transmission or multiplexing are disclosed herein. An example method for wireless communication at a UE includes receiving, from a base station, an overlapping uplink transmission configuration. The example method also includes detecting an occurrence of an overlapping uplink transmission comprising at least a portion of uplink control information and at least a portion of uplink data overlapping in a time domain. Additionally, the example method includes transmitting at least one of the uplink control information or the uplink data based on the overlapping uplink transmission configuration.

Abstract: A scheduling entity can configure semi-persistent scheduling (SPS) resources for downlink data and selectively receiving channel measurements and interference measurements from a user equipment. The scheduling entity can trigger the channel measurements and interference measurements using various methods including SPS configuration activation/reactivation/deactivation, DMRS based triggering, and DCI based triggering. The scheduling entity can benefit from more frequent and/or aperiodic interference and/or channel measurements in performing channel precoding, selecting a modulation and coding scheme (MCS), and estimating/predicting interference, noise, and channel quality at the UE. SPS configured channel and interference measurements also benefit the UE in data decoding that can result in a lower error ratio and higher data rate.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a modulation and coding scheme (MCS) for an uplink communication of the UE; identify a set of beta values for uplink control information of the uplink communication according to a mapping between the set of beta values and the MCS, wherein the set of beta values is for determination of a number of resource elements or modulation symbols for the uplink control information; and transmit the uplink control information based at least in part on the set of beta values. Numerous other aspects are provided.

Abstract: A base station may transmit, to a user equipment (UE), an instruction for scheduling a physical uplink shared channel (PUSCH) transmission. The PUSCH transmission may be overlapping with at least one of a slot boundary or a symbol that is configured invalid for a PUSCH by the base station, and the UE may configure a first partial PUSCH and a second partial PUSCH, the second partial PUSCH being a subset of the PUSCH transmission and including a single symbol length. The UE may schedule the second partial PUSCH based on the instruction received from the base station.
