摘要： In an aspect, a UE and BS communicate data traffic in accordance with a first bandwidth part (BWP) configuration. The BS sends, to the UE in association with communication of a plurality of reference signals for positioning (e.g., PRS, SRS-P, etc.), an indication of a second BWP configuration that includes a different bandwidth than the first BWP configuration. The UE and BS communicate, for a duration of the communication of the plurality of reference signals for positioning, at least the plurality of reference signals for positioning in accordance with the second BWP configuration.

摘要： Method and apparatus for switching between SS-TWR and DS-TWR. The apparatus reserves resources for transmission of a first SL-PRS in a first time slot. The apparatus transmits, to a second UE, the first SL-PRS within the first time slot. The apparatus receives, from the second UE, a second SL-PRS at a second time based on the first time slot and a response time associated with transmission of the second SL-PRS in response to the first SL-PRS. The apparatus measures a time difference between the transmission of the first SL-PRS and reception of the second SL-PRS to determine if a third SL-PRS is to be transmitted to the second UE.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration identifying a first set of frequency resources for transmitting a sounding reference signal, where the sounding reference signal may be used at least for downlink channel state information acquisition. The UE may receive an indication of an association between the configuration for the sounding reference signal and a second set of frequency resources and determine, based on the association, values for one or more sounding reference signal transmission parameters for the first set of frequency resources. The UE may transmit the sounding reference signal on the first set of frequency resources based on the determined one or more values.

摘要： Positioning assistance data (PAD) is encoded in positioning System Information Blocks (posSIBs) and periodically broadcast by abase station in a differential manner A PAD element that is different relative to previously broadcast PAD is encoded in a block of posSIB separately from PAD that is unchanged. Another separate block of posSIB includes reference encoding identifying the changed PAD and provides scheduling information. A UE may decode the reference encoding and determine whether the UE has previously decoded the changed PAD. If the UE has previously received the PAD, but has not yet received the new or changed PAD, the UE may receive and decode the block of posSIB with only the changed PAD, thereby increasing efficiency.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first configuration of one or more channel state information reference signal resources and a second configuration of a channel state information report associated with the one or more channel state information reference signal resources. In some cases, the second configuration may include at least one of an indication of a codebook, a set of codebook restriction sets, and a configured bandwidth. The UE may then identify a mapping between one or more frequency-domain subbands of the configured bandwidth and each codebook restriction set of the set of codebook restriction sets, and transmit, to the base station, a report indicating one or more precoding matrix indicators from the codebook for each of the one or more frequency-domain subbands based on the mapping.

摘要： Methods, systems, and devices for wireless communications are described. In some wireless communications systems, signaling may be impacted by Doppler shifts associated with communications between a user equipment (UE) and one or more devices in the system. To account for the Doppler shifts, the UE may receive a Doppler shift measurement configuration to use for estimating one or more Doppler shift parameters associated with one or more reference signals transmitted from the one or more transmission reception points (TRPs). The measurement configuration may include a measurement restriction parameter which indicates a number of durations that the UE may use to estimate the Doppler shift parameters. The UE may generate and transmit a measurement report for the estimated Doppler shift parameters according to a determined reporting accuracy and granularity.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of a cluster of nodes that are able to provide signals to the UE for energy harvesting at the UE. The UE may receive, from the cluster of nodes, the signals based at least in part on the indication of the cluster of nodes. The UE may harvest energy from the signals for charging a battery of the UE. Numerous other aspects are described.

摘要： Techniques are provided for utilizing positioning reference signals (PRS) in full duplex scenarios. An example method of providing positioning information for a mobile device to a base station includes receiving, at the mobile device, a positioning request and an accuracy requirement from the base station, determining one or more positioning reference signal transmissions based on the accuracy requirement, obtaining position measurement information based on the one or more positioning reference signal transmissions, and providing the position measurement information to the base station.

摘要： Methods, systems, and devices for wireless communications are described that support virtual resource block (RB) to physical RB mapping in duplex slots. The described techniques enable a user equipment (UE) to select an interleaving configuration such as a full duplex or half duplex interleaving configuration for a slot that may be configured for full duplex communications. In some cases, the UE may use a default interleaving configuration for a given slot or may determine the interleaving configuration based on a bandwidth part (BWP) position or resource bandwidth within the slot, such as a location within the frequency domain of a downlink BWP relative to an uplink BWP.
