Abstract: Methods, systems, and devices for codebook-based beamforming considerations for reconfigurable intelligent surfaces (RISs) are described. For example, an RIS may transmit, to a first wireless device, an indication of a capability of using different types of precoders for generating a codebook for the RIS for redirecting wireless signals. The codebook may include codewords associated with weights for respective elements of the RIS. In some cases, the RIS may receive, from the first wireless device, a type of precoder for generating the codebook. As such, the RIS may adjust one or more elements using the weights for the respective elements based on receiving the indication and in accordance with training a communication link between the first wireless device and a second wireless device via the plurality of elements. In some examples, the RIS may receive, from the first wireless device, an index corresponding to a codeword.

Abstract: Certain aspects of the present disclosure provide techniques for repetition cancellation in full duplex communications. A method of wireless communication includes receiving scheduling information from a base station, wherein: the scheduling information schedules transmission of a plurality of uplink channel repetitions in a plurality of slots, the plurality of uplink channel repetitions is associated with a first sequence of redundancy versions (RVs), each repetition in the plurality of uplink channel repetitions assigned a different RV in the first sequence of RVs, and the plurality of slots include at least one full duplex slot comprising an uplink subband for uplink transmissions and a downlink subband for downlink transmissions; receiving an indication to cancel one or more repetitions of the plurality of uplink channel repetitions scheduled by the scheduling information; and taking one or more actions related to transmitting one or more remaining non-canceled repetitions of the plurality of UL channel repetitions.

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 subset size parameter associated with a first priority, and an indication of a second subset size parameter associated with a second priority. The UE may determine a first set of HARQ-ACK/NACK feedback associated with downlink communications having the first priority and a second set of HARQ-ACK/NACK feedback associated with downlink communications having the second priority. The UE may select a first subset of HARQ-ACK/NACK feedback from the first set of HARQ-ACK/NACK feedback based on the first subset size parameter, and a second subset of HARQ-ACK/NACK feedback from the second set of HARQ-ACK/NACK feedback based on the second subset size parameter. The UE may transmit, during the uplink slot, the first subset and/or the second subset of HARQ-ACK/NACK feedback. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for relay path selection in wireless communications are described, where multiple relay paths are available between a source and a destination. A first node (e.g., a source node or destination node) may determine reference signal resources for a set of reference signals to be transmitted between the first node and a second node through a corresponding relay path of a set of relay paths. The first node may receive the set of reference signals measure one or more parameters for each reference signal. Alternatively, the first node may transmit the set of reference signals and receive an indication of one or more measured parameters from the second node. The first node may determine a set of end-to-end metrics for the set of relay paths, and select a relay path for communications with the second node based on the set of end-to-end metrics.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, from at least an acknowledgment (ACK)-only feedback configuration and a negative ACK (NACK)-only feedback configuration and based at least in part on an error rate and a traffic condition associated with a semi-persistent scheduling (SPS) resource allocation, a feedback configuration for the SPS resource allocation. The UE may transmit feedback regarding the SPS resource allocation using the selected feedback configuration. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for providing quantized channel state information (CSI) feedback that may be used to adjust transmission parameters for retransmissions after a negative acknowledgment. An example method performed by a user equipment (UE) generally includes generating hybrid automatic repeat request (HARQ) feedback for a downlink transmission from a network entity, generating quantized channel state information (CSI) feedback, transmitting the HARQ feedback and quantized CSI feedback to the network entity in a physical uplink control channel (PUCCH) transmission, and processing a retransmission of the downlink transmission, sent with transmission parameters adjusted based on the quantized CSI feedback if the HARQ feedback indicates a decoding failure.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) may receive different configurations for determining a first transmit power for data transmissions and a second transmit power for energy harvesting transmissions. The different configurations may include different parameters for determining (e.g., calculating) the first transmit power and the second transmit power. In some aspects, the transmitting UE may also receive an indication of the second transmit power from a receiving UE such that the second transmit power may be determined in accordance with the capabilities of the receiving UE (e.g., based on an energy harvesting circuit at the UE). The indication of the second transmit power may be an indication of one or more parameters used to determine (e.g., calculate) the second transmit power.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support dynamic network-side cell discontinuous reception (DRX) control and scheduling. In a first aspect, a method of wireless communication includes transmitting an end of transmit (TX) traffic indicator. The method also includes receiving an early termination indicator associated with a scheduled network-side cell discontinuous reception (DRX) active time. The method further includes refraining from transmitting data traffic during at least a remainder of the scheduled network-side cell DRX active time. Other aspects and features are also claimed and described.

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.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a network may support different network energy states (NESs). A network entity may transmit, for a user equipment (UE), an indication of a currently active NES, for example, for a serving cell or for a non-serving cell. The UE may determine a radio measurement threshold, a relaxation configuration, or both based on the active NES for the network entity. A network entity associated with the serving cell or non-serving cell may transmit a synchronization signal block (SSB) using one or more parameters associated with the active NES, and the UE may receive the SSB and perform one or more measurements based on the active NES (e.g., based on the radio measurement threshold, the relaxation configuration, or both). The UE may communicate with the network based on the one or more measurements.
