Abstract: Certain aspects of the present disclosure provide techniques for managing scheduling of wireless communications. A method that may be performed by a user equipment (UE) includes receiving, from a base station, one or more configurations indicating a plurality of minimum scheduling offset values; receiving, from the base station, a signal indicating one of the minimum scheduling offset values as an updated value to be used for communications with the base station and a type of scheduling; determining a delay based on the type of scheduling; and after the reception of the signal, using the updated value for communications with the base station based on the determined delay.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a reduced-capability user equipment (UE) receives, from each of one or more premium UEs, one or more parameters indicating a quality of a location estimate of the premium UE, selects at least one premium UE based on the quality of the location estimate of the at least one premium UE, and derives a location estimate of the reduced-capability UE based on the location estimate of the at least one premium UE. In another aspect, a reduced-capability UE transmits, to at least one premium UE, a request to perform one or more positioning measurements of one or more downlink reference signals, receives, from the at least one premium UE, a measurement report comprising the one or more positioning measurements, and determines a location estimate of the reduced-capability UE based on the one or more positioning measurements in the measurement report.

Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates an association between a sounding reference signal (SRS) resource set and a downlink reference signal resource to be used to determine a transmission property of one or more SRSs in the SRS resource set, wherein the downlink reference signal resource is associated with a first set of ports to be used for performing measurement of the downlink reference signal resource. The UE may determine the transmission property of the one or more SRSs in the SRS resource set using fewer ports than a number of ports included in the first set of ports, based at least in part on a determination that the UE is operating in a power saving mode. The UE may transmit the one or more SRSs using the transmission property. Other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication scheduling. An example method that may be performed by a user equipment (UE) includes receiving, from a base station, one or more configurations indicating wireless communication resources including at least one of a plurality of bandwidth parts (BWP) or a plurality of component carriers (CCs); receiving, from the base station, control signaling indicating a scheduling offset to communicate with the base station via at last one of the BWPs within at least one of the CCs; determining a value of the scheduling offset based at least in part on a minimum scheduling offset value; and taking at least one action in response to the determination.

Abstract: Methods and apparatus are disclosed according to certain aspects of the present disclosure. The methods and apparatus effect determination that a transmission configuration indicator (TCI) state is to be changed for a wireless transmission channel, where the channel includes time domain bundling of demodulation reference signals (DMRSs) across two or more symbols. Responsive to the determination that the TCI state is to be changed, the time domain bundling of the DMRSs in the transmission channel is selectively stopped prior to the TCI state change.

Abstract: Certain aspects of the present disclosure provide techniques for rate matching PDSCH around NZP CSI RS transmissions in multi-TRP scenarios. In some cases, a network entity may signal a rate matching behavior to a user equipment (UE) for processing a physical downlink shared channel (PDSCH) configured with a first quasi co-location association and transmitted from a first transmission reception point (TRP) that potentially collides with one or more types of non-zero power (NZP) reference signals (RS) configured with a second quasi co-location association and transmitted from a second TRP using one or more resource sets.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a wakeup signal search space (WUS-SS) set for a physical downlink shared channel (PDCCH) wakeup signal (WUS). The UE may detect the PDCCH WUS in the WUS-SS set based at least in part on monitoring the WUS-SS set. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure a UE to transmit a cross link interference reference signal (CLI-RS) using a bandwidth and frequency similar to those used for a synchronization signal. In another aspect, a BS may may configure a UE to measure a cross link interference reference signal (CLI-RS) transmitted using a bandwidth and frequency similar to those used for a synchronization signal. In other aspects, a base station may transmit, to a UE, an instruction to transmit or measure a CLI-RS. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station (BS) may detect remote interference, with one or more uplink communications on a physical uplink shared channel (PUSCH) associated with the first BS, caused by propagation of one or more reference signal (RS) communications, transmitted by a second BS, out of a coverage area of the second BS and into a coverage area of the first BS due to reflection of the one or more RS communications. The coverage area of the first BS and the coverage area of the second BS are non-overlapping coverage areas. The first BS may adjust, based at least in part on detecting the remote interference, one or more radio resource allocations of the PUSCH associated with the first BS. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine to configure a user equipment (UE) to operate in a transmission/reception point (TRP) mode, wherein the TRP mode is a single-TRP mode or a multi-TRP mode. The BS may configure the UE to operate in the TRP mode based at least in part on a bandwidth part (BWP) switch or a trigger to switch between the multi-TRP mode and the single-TRP mode within a BWP. Numerous other aspects are provided.
