Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may monitor a set of operational conditions associated with the UE. Based on the monitoring, the UE may transmit a request for an indication identifying a PDCCH monitoring location associated with receiving a next DCI communication. A base station may receive the request and determines whether to grant the request. Based on the determination, the base station may selectively transmit the indication to the UE. The UE may monitor in the PDCCH monitoring location if the indication is received in response to the request.

Abstract: Aspects of the present disclosure provide techniques for configuring device-to-device (D2D) communication in new radio (NR) for one or more user equipments (UEs). Specifically, features of the present disclosure provide techniques for initial beam-pairing for sidelink communication that optimize communication resources (e.g., resource pools) by indicating the direction of traffic (e.g., transmit or receive) during the initial beam-pairing procedure and to establish sidelink communication without the need for scheduling request transmissions between the UEs.

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, apparatuses and methods related to communicating control information are provided. A user equipment (UE) may include a memory, a transceiver, and at least one processor coupled to the memory and the transceiver, wherein the UE is configured to receive a first reference signal associated with a first serving cell, measure at least one of a power delay profile (PDP) associated with the first reference signal or an angle of arrival (AOA) associated with the first reference signal, and determine a beam failure associated with a second reference signal associated with a second serving cell based on the at least one of the PDP or the AOA, wherein the second serving cell is different from the first serving cell.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may detect and report blockage conditions based on measuring signal strengths of reference signals. A UE may determine a slew rate for the signal strength, corresponding to a rate of change of a signal strength parameter (e.g., a reference signal received power (RSRP) or a received signal strength indicator (RSSI)) with respect to time, and report the slew rate to a base station to indicate signal strength degradation (e.g., due to a blockage). In some examples, the UE may define multiple slew rates associated with different rates of change of the signal strength parameter with respect to time. When the UE crosses a level of slew rate, the UE may indicate this to the base station to initiate mitigation procedures. In some examples, the techniques described herein may be extended to reporting slew rates for multiple beams.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.
