    Abstract: A base station may identify an association between a set of physical cell identifiers (PCIs) identifying different transmission reception points (TRPs) and a set of transmission configuration indicator (TCI) states for a user equipment (UE). The base station may transmit a TCI state and PCI association indication to the UE. The UE may receive a downlink transmission using a receive beam associated with a TCI state, and may identify a PCI of the set of PCIs to use to decode the received downlink transmission. In cases where the TCI state used to receive the downlink transmission is associated with multiple PCIs, the UE may select a default PCI from the multiple PCIs, and may decode the received transmission accordingly. In some examples, the UE may receive reference signals from one or more of the serving TRPs and may identify a PCI to use to decode the received reference signals.

    Abstract: Described are methods, systems, and devices for processing a Positioning Reference Signal (PRS) or other reference signal usable for determining a position of a User Equipment (UE). In some aspects, a UE is configured to report to a network entity information indicating a number of receive (Rx) chains used to determine one or more positioning measurements, thereby indicating the amount of uncertainty in the positioning measurement(s) and the precision of a resulting position estimate. In some aspects, a UE is configured to receive multiple PRS signals that at least partially overlap in time and to process each PRS using a separate set of Rx chains to obtain positioning measurements. As part of the processing of a PRS, the UE may align a search window to the PRS. In this manner, different search windows can be maintained for different PRS signals to maximize the signal-to-noise ratio of each PRS.

    Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may use partial frequency sounding with different frequency subhop patterns so that a portion (which may be referred to as a subhop) of configured sounding reference signal (SRS) resources (e.g., a hop) are sounded. In some cases, a UE may receive a control message from a network entity identifying the frequency subhop pattern. In some cases, the network entity may configure a UE to transmit repetitions of the SRS in a same hop across consecutive symbols to increase a probability that the transmissions are successfully received and decoded by the network entity. As such, the network entity may configure a repetition factor for the frequency subhop pattern. In some cases, the frequency subhop pattern may introduce a frequency overlap between subhops.

    Abstract: An anchor UE may move or have a low transmission power and impact the accuracy of positioning estimates of a target UE based on measurements of the PRSs associated with the anchor UE. One or more candidate anchor UEs may be selected or excluded from being used for positioning based on one or more of a measurement quality metric of a position measurement of a candidate anchor UE, a mobility status of the candidate anchor UE, or a GDOP associated with the candidate anchor UE. A mobility status of the candidate anchor UE may be derived from reported positions of the candidate anchor UE or obtained from the candidate anchor UE. A UE selected as an anchor UE is used for positioning of a target UE, and a UE downselected from being an anchor UE is excluded from use for positioning of the target UE.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a method of wireless communication performed by a transmission/reception point (TRP) includes transmitting, at a first time and to a receiving entity, a first beam response report that describes, using a first level of granularity, beam responses of a set of positioning resources, each positioning resource to be transmitted by the TRP at different times using different beams; transmitting, at a second time and to the receiving entity, a second beam response report that describes, using a second level of granularity different from the first level of granularity, beam responses of at least a portion of the set of positioning resources; and transmitting the set of positioning resources using the different beams. The TRP may receive positioning information from the receiving entity, the positioning information comprising measurements of at least some of the positioning resources, a positioning estimate, or combinations thereof.

    Abstract: Techniques for positioning assistance data (AD) delivery for reduced signaling overhead may comprise determining a combined positioning AD for a requesting user equipment (UE) based at least in part on the area ID in which the requesting UE is located. The combined positioning AD may include positioning AD for the first area and one or more additional areas. For each of the area, the positioning AD may comprise information regarding Positioning Reference Signal (PRS) resources, Base Station Almanac (BSA) information, or both, to be used for positioning the requesting UE within the respective area. The first area and the one or more additional areas may comprise cells of the wireless communication network or sidelink (SL) group zones.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a physical sidelink shared channel (PSSCH) transmission in an uplink slot or in a smaller-bandwidth slot. The UE may transmit, to the second UE and based at least in part on the PSSCH transmission, hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback in a physical sidelink feedback channel (PSFCH) resource of the uplink slot or of the smaller-bandwidth slot based at least in part on a PSSCH-to-PSFCH mapping, wherein a quantity of PSFCH resources differs between the uplink slot and the smaller-bandwidth slot based at least in part on different resource pool bandwidths between the uplink slot and the smaller-bandwidth slot. Numerous other aspects are described.
