Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE receives a positioning configuration, the positioning configuration including at least an identifier of a first downlink reference signal from a neighboring cell to be used for estimating a downlink path loss or determining an uplink spatial transmit beam, determines that a first downlink reference signal received from the neighboring cell cannot be used for estimating the downlink path loss or determining the uplink spatial transmit beam, in response to the determination, estimating the downlink path loss or determining the uplink spatial transmit beam based on a second downlink reference signal received from the neighboring cell or a serving cell, and transmits an uplink reference signal for positioning based on the estimated downlink path loss, the determined uplink spatial transmit beam, or a combination thereof.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

Abstract: A reference signal periodically transmitted by a base station in a wireless network can have certain proprietary properties to help prevent detection and utilization of the signal for unauthorized positioning of mobile devices. More specifically, a network node can obscure and introduce time-variation in mapping between positioning signals and a corresponding physical base stations. The network node may also introduce time variations in fields of a base station almanac (BSA) provided to subscribing user equipments (UEs). The information transmitted to the subscribing UEs may be encrypted.

Abstract: Certain aspects of the present disclosure provide techniques for avoiding transmission configuration indication (TCI) reselection (e.g., due to some bandwidth part (BWP) switching scenarios). An exemplary method generally includes configuring a UE with TCI state information for communication via multiple BWPs, wherein the TCI state information indicates quasi co-location (QCL) assumptions of at least first and second types and determining whether to reconfigure the TCI state of the UE to reflect a BWP switch, based on one or more rules that define BWP switching for reference signals (RSs) of at least one of the QCL assumption types without TCI state reconfiguration. Other aspects and embodiments are also claimed and described.

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: Disclosed are techniques for using sounding reference signal (SRS) for positioning. In an aspect, a UE receives an SRS configuration, the SRS configuration defining one or more SRS resource sets, each SRS resource set comprising one or more SRS resources, and each SRS resource comprising one or more SRS ports, wherein at least one SRS port of at least one SRS resource of at least one SRS resource set defined in the SRS configuration is usable by the UE at least for positioning. The UE transmits a positioning SRS utilizing one or more positioning SRS ports, wherein the positioning SRS is transmitted in a positioning SRS pattern such that across N consecutive symbols, where N is greater than or equal to two, SRS resource elements (REs) to which the one or more positioning SRS ports are mapped are staggered in frequency and use each of the N consecutive symbols.

Abstract: Disclosed are techniques for muting positioning reference signals. In aspects, a location server sends, to a user equipment (UE), a plurality of positioning reference signal configurations and one or more positioning reference signal muting configurations associated with a transmission-reception point (TRP) identifier (ID) and/or a positioning reference signal ID. A first TRP sends, to the UE, a command triggering at least one positioning reference signal muting configuration, wherein the triggered positioning reference signal muting configuration indicates that: the one or more positioning reference signals of the one or more positioning reference signal occasions of at least one positioning reference signal configuration are not being transmitted, or the one or more positioning reference signals of the one or more positioning reference signal occasions of all of the plurality of positioning reference signal configurations are not being transmitted, and mutes positioning reference signals according to the triggered positioning reference signal muting configurations.

Abstract: Disclosed are techniques for receiving reference radio frequency (RF) signals for positioning estimation. In an aspect, a user equipment (UE) receives, from a network node, multiple resource sets for tracking (TRSs). Each TRS comprises a plurality of reference signal resources. The multiple TRSs are signals from a same antenna port or are quasi-co-located signals. The UE processes the multiple TRSs to determine positioning-related quantity(ies). The UE can estimate its position based on the positioning-related quantity(ies) and/or send the positioning-related quantity(ies) to the network.

Abstract: Aspects of the disclosure relate to determining a transmission configuration indication (TCI) state for receiving a multi-transmission point (TRP) communication. A receiving device receives a configuration message indicating a lowest control resource set identifier (CORESET ID) for receiving one or more downlink control information (DCI) and determines whether a state of the receiving device is within a scheduling threshold duration for decoding DCI. The receiving device then determines a TCI state for receiving data based on a TCI state associated with the lowest CORESET ID if the state of the receiving device is within the scheduling threshold duration, wherein the TCI state associated with the lowest CORESET ID indicates one or more sets of quasi co-location (QCL) parameters. The receiving device then receives the data from one or more transmission points (TRPs) based on the one or more sets of QCL parameters.
