Abstract: Aspects relate to feedback such as HARQ-ACK/NACK feedback in wireless communication systems. A predetermined condition, such as a timeout condition, is configured for a user equipment (UE) to determine whether a HARQ-less feedback should be implemented in the UE. In a particular aspect, the predetermined condition may be a timeout period or some other condition where a UE will cancel or discard feedback if the UE is unable to respond within the timeout period or meet the condition imposed. Various conditions may be imposed and are communicated through either radio resource control (RRC) signaling or downlink control information (DCI) parameters, or a combination thereof.

Abstract: A user equipment may be configured to assist channel reconstruction using partial spatial sounding. In some aspects, the user equipment (UE) may transmit, to another device, correlation capability information indicating a sounding reference signal (SRS) grouping capability of the UE, and receive, from the other device, reference signal (RS) configuration information for configuring a sounding procedure to be performed by the UE. Further, the UE may transmit a reference signal to the other device over a reference antenna port of the UE to allow the other device to determine channel information for another antenna port of the UE, and receive data from the other device based on the channel information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first dormancy state, of a plurality of dormancy states, for a set of frequency resources within a bandwidth part of a component carrier, wherein each dormancy state of the plurality of dormancy states is associated with a respective set of activities that are enabled for that dormancy state. The UE may switch the set of frequency resources to the first dormancy state. Numerous other aspects are described.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for duplex switching based on network power modes. A UE may receive a first indication that a first power mode of a network entity is associated with a first duplex type for the network entity and a second power mode of the network entity is associated with a second duplex type for the network entity. The first duplex type and the second duplex type may correspond to at least one of full-duplex communication or half-duplex communication. The UE may receive a second indication of a switch from the first power mode associated with the first duplex type to the second power mode associated with the second duplex type and communicate with the network entity based on the second power mode and the second duplex type for the network entity.

Abstract: A UE may transmit, to a base station, and the base station may receive, from the UE, a turbo HARQ-ACK message corresponding to a first downlink transmission. The turbo HARQ-ACK message may include an indication of a duplexing mode associated with a second downlink transmission. The base station may transmit, to the UE, and the UE may receive, from the base station, the second downlink transmission based on the indication of the duplexing mode. The indication of the duplexing mode may correspond to a full-duplex mode or a half-duplex mode. The first downlink transmission may correspond to a first TB. The second downlink transmission may correspond to a second TB. The turbo HARQ-ACK message may further indicate a requested delta MCS for the second downlink transmission with respect to an MCS associated with the first downlink transmission.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel state information (CSI) reporting. One aspect provides a method for wireless communication by a first user equipment (UE). The method generally includes transmitting, to a second UE, an indication of a capability of the first UE for reporting sidelink channel state information (SL-CSI) to the second UE, receiving, from the second UE, a request for SL-CSI, and reporting SL-CSI to the second UE subject to the capability of the first UE for reporting SL-CSI to the second UE.

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.
