    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: Certain aspects of the present disclosure provide techniques for beam indication set reuse. A method for a wireless communication that may be performed by a user equipment (UE) includes receiving signaling configuring the UE with a beam indication set. The method includes receiving an indication to apply the configured beam indication set to multiple bandwidth parts (BWPs) and/or multiple component carriers (CCs). The method includes applying the beam indication set to a BWP or CC based on the indication. The beam indication set may be for uplink or downlink communications. The beam indication set may be a transmission configuration indicator (TCI) state set or spatial relation set. Other aspects and features are also claimed and described.

    Abstract: A user equipment (UE) includes: a transceiver configured to send and receive communications signals wirelessly to and from a network entity; a memory; and a processor, communicatively coupled to the transceiver and the memory, configured to: send, via the transceiver to the network entity over a physical layer uplink channel, a positioning assistance request for the network entity to provide positioning assistance information indicating one or more parameters for signal exchange of one or more positioning reference signals between the UE and another device; receive the positioning assistance information from the network entity via the transceiver over a physical layer downlink channel; and perform one or more UE-device positioning functions in accordance with the positioning assistance information.
