Abstract: Disclosed are techniques for wireless positioning. In an aspect, a mobile device receives a timing synchronization offset parameter for a first cell of a set of cells, wherein the timing synchronization offset parameter represents a difference between a system frame number (SFN) initialization time of the first cell and an SFN initialization time of a reference cell, and processes the timing synchronization offset parameter for the first cell based on the SFN initialization time of the reference cell having changed.

Abstract: Disclosed are various techniques for wireless positioning. In an aspect, the time that a user equipment (UE) spends on performing positioning reference signal (PRS) measurements is reduced, by lengthening the PRS measurement period (P) and/or by reducing the PRS symbol duration (K). These modifications may be performed by the UE or by a location management server or other network node and may be made in consideration of the UE's mobility status and other environmental or operating conditions of the UE. In an aspect, a network entity may determine P and K to be used by the UE, and may indicate, to the UE, the P and the K to be used by the UE for measuring at least one PRS. The UE may then use the P and the K for measuring at least one PRS.

Abstract: Sounding Reference Signal (SRS) transmission for positioning can be utilized on flexible symbols. Techniques disclosed for transmitting a reference signal for positioning comprise receiving, from a serving base station, a message comprising an indication to transmit a SRS on a set of symbols of an orthogonal frequency division multiplexing (OFDM) slot. Techniques may also comprise determining the SRS is to be used for positioning, and receiving, from the serving base station, downlink control information (DCI) having a slot format indicator (SFI) that designates a subset of the set of symbols as flexible. Techniques may also comprise transmitting the SRS on at least a portion of the subset.

Abstract: Some aspects provide a method for wireless communication by a user equipment (UE). The method generally includes receiving signaling of a spatial preemption indication (PI), identifying, based on the spatial PI, at least one beam that the UE is preempted from using for at least one of transmitting or receiving at least one target signal, and refraining from using the identified beam for transmitting or receiving the target signal, for at least a time period.

Abstract: Certain aspects of the present disclosure provide techniques for fast adaptation of transmission properties of sounding reference signal (SRS) resource sets. A method that may be performed by a user equipment (UE) includes receiving sounding reference signal (SRS) configuration information, configuring the UE with one or more SRS resource sets, wherein each of the one or more SRS resource sets comprises one or more SRS resources; receiving signaling comprising a field indicating which of the one or more SRS resources in the one or more SRS resource sets are active and which of the one or more SRS resources in the one or more SRS resources sets are inactive; and transmitting one or more SRSs using only the one or more SRS resources that are active.

Abstract: Disclosed are techniques for computing and reporting a relevance metric for a positioning beacon beam. In an aspect, a first node receives, from a second node, a plurality of beams, determines a relevance metric for each of one or more beams of interest from the plurality of beams, wherein the relevance metric for each beam of the one or more beams of interest is based on a time of arrival at the first node of the beam and a signal strength of the beam, and sends, to the second node, a report identifying each of the one or more beams of interest and including the relevance metric for each of the one or more beams of interest.

Abstract: In an aspect, a UE receives, from a network entity, a configuration of PRS or SRS-P resources for a positioning session, receives a configuration of at least one BWP from a serving BS, identifies a time-domain period for the positioning session where a set of parameters associated with the at least one BWP is to remain constant to achieve a first positioning accuracy requirement. The UE either performs positioning measurements on one or more of the PRS resources during the positioning session or transmits on one or more of the SRS-P resources during the positioning session. The UE determines an active BWP transition during the time-domain period from a first BWP to a second BWP that is associated with one or more changes to the set of parameters.

Abstract: Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.
