Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration associated with channel measurement resources (CMRs). The UE may perform downlink channel measurements associated with the CMRs, wherein the downlink channel measurements are associated with one or more time instances. The UE may store the downlink channel measurements associated with the one or more time instances for a period of time at the UE. The UE may transmit, to the network entity and based at least in part on a request, at least a portion of the downlink channel measurements associated with the one or more time instances. Numerous other aspects are described.

Abstract: Aspects relate to adaptively determining L1-reference signal received power (L1-RSRP) quantization in connection with channel state information (CSI) report. A user equipment receives a CSI configuration type and an identification of a CSI report quantity associated with a first number of channel measurement resources (CMRs). The user equipment reports a quantization scheme to quantize the CSI report quantity based on a total number of payload bits available to report the CSI report quantity. Aspects described herein may be applied to predictive beam management in some examples.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain an indication of a performance-complexity tradeoff parameter value associated with a quantity of iterations and channel orthogonality for an algorithm for a lattice reduction of a first matrix for a downlink communication, a frequency domain granularity for the lattice reduction, and/or a time domain granularity for the lattice reduction. The UE may receive the downlink communication that corresponds to the first matrix and perform the lattice reduction to transfer the first matrix to a second matrix based at least in part on the performance-complexity tradeoff parameter value, the frequency domain granularity, and/or the time domain granularity. The UE may perform multiple-input-multiple-output detection of the downlink communication using the second matrix. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to UE cooperation are provided. A base station (BS) may assist a UE in cooperating with other UEs. A UE may transmit a cooperative UE update request to aBS, indicating a number of candidate cooperative UE sets. The UE may also transmit information to the BS about the candidate cooperative UE sets such as UE capability information, location information, and channel measurements. Additional measurements maybe requested by the BS. The BS may use the information from the UEs together with BS-side information such as configuration information and TRP information in order to determine which of the candidate cooperative UE sets is preferred. The BS may then configure and communicate with selected cooperative UE set.

Abstract: An apparatus, such as a base station, may determine channel conditions associated with at least two carriers on which communication with another apparatus is configured. The apparatus may encode a dataset into a set of protocol data units (PDUs) using fountain coding based on the channel conditions. The apparatus may send a first subset of the set of PDUs to the other apparatus on a first carrier of the at least two carriers. The apparatus may send a second subset of the set of PDUs to the other apparatus on a second carrier of the at least two carriers. Another apparatus, such as a user equipment (UE), may receive the set of PDUs from the apparatus over the at least two carriers, and may decode the set of PDUs to obtain a dataset using fountain coding.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.
