Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for bandwidth adaptation. One example method by a user equipment (UE) includes selecting a first subband of multiple subbands of a bandwidth for communication on a sidelink channel, wherein each subband of the multiple subbands is associated with a configuration for the communication on the sidelink channel, the selection being based on the configuration associated with the first subband, and communicating on the sidelink channel using the first subband and in accordance with the configuration associated with the first subband.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may map hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback that includes a first HARQ-ACK bit associated with a high priority and a second HARQ-ACK bit associated with a low priority to a sequence cyclic shift value that provides an unequal reliability between the first HARQ-ACK bit and the second HARQ-ACK bit. The UE may transmit, to a base station, the HARQ-ACK feedback via a physical uplink control channel (PUCCH) format 0. Numerous other aspects are provided.

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: A user equipment (UE) determines an occurrence of a triggering event for providing negative acknowledgment (NACK) based feedback for a semi-persistent scheduling (SPS) transmission. The apparatus monitors for the SPS transmission. The apparatus transmits a NACK if the SPS transmission is not successfully received and refrains from sending an ACK if the SPS transmission is successfully received based on the occurrence of the triggering event for providing NACK based feedback. The base station determines an occurrence of a triggering event for a UE to provide NACK based feedback for an SPS transmission. The apparatus transmits the SPS transmission and determines that the UE successfully received the SPS transmission based on an absence of a NACK from the UE for the SPS transmission.

Abstract: Certain aspects of the present disclosure provide techniques for configuring data transmission. Aspects relate to determining a data transmission configuration utilizing a machine-learning based algorithm, such as a data transmission configuration for ultra-reliable low-latency communication (URLLC) applications. A method that may be performed by a base station (BS) includes receiving a feedback report from a user equipment (UE) including an indication of a first state corresponding to a plurality of channel condition parameters and determining one or more actions based, at least in part, on the first state. The BS may determining the one or more actions utilizing a machine learning algorithm that uses a second state, where the second state is based, at least in part, on the first state.

Abstract: In an aspect, a UE measures interference from one or more neighbor base stations on a set of resources over a period of time, and determines an interference burst dynamic associated with the set of resources based on the measured interference over the period of time. The UE transmits an interference measurement report comprising an indication of the interference burst dynamic to a serving base station of the UE. The serving base station performs at least one action based in part upon the prediction.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a plurality of communications on a plurality of component carriers. The UE may transmit, to the base station, uplink control information that includes a first portion that indicates respective feedback for the plurality of communications, and a second portion that indicates an average channel quality indicator (CQI) value and respective differential values, relative to the average CQI value, for multiple communications, of the plurality of communications, for which negative acknowledgment feedback is transmitted. Numerous other aspects are provided.

Abstract: Wireless devices are adapted to facilitate beamforming communications in wireless networks. A wireless device may identify a first beam group with a number of beams equal to a maximum number of allowed beams, and a second beam group with a number of beams less than the maximum number of allowed beams. Channel statistics may be estimated for each of the first beam group and the second beam group, and the second beam group may be selected for communications when the second beam group is determined to have at least substantially equal or greater channel statistics compared to the first beam group. Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message, from a network entity, indicating assistance information including a decoding order, decoder iteration instructions, or both, for a first set of repetitions of a data transmission. The UE may monitor for and receive the first set of repetitions from the network entity and decode the first set of repetitions based on the assistance information from the network entity. Based on decoding the first set of repetitions, the UE may transmit a feedback message to the network entity indicating whether the UE successfully decoded the first set of repetitions.
