Abstract: Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits capability information indicating a maximum number of downlink resources for both positioning reference signal (PRS) resources and downlink resources for one or more second downlink channels or signals that the UE is capable of processing per unit of time, receives, from a serving transmission-reception point (TRP), a configuration of one or more downlink resources for the one or more second downlink channels or signals, wherein a number of the one or more downlink resources is less than the maximum number, and receives, from a location server, a configuration of one or more PRS resources for the serving TRP, one or more neighboring TRPs, or both, wherein a number of the one or more PRS resources is less than the maximum number.

Abstract: Certain aspects of the present disclosure generally relate to randomization of positioning reference signal (PRS) frequency offsets and muting patterns in long term evolution (LTE) for enhanced observed time difference of arrival (eOTDOA). According to certain aspects, a method is provided for wireless communications which may be performed, for example, by a base station (BS). The method generally includes randomly selecting at least one parameter used to determine a set of time-frequency resources for transmitting positioning reference signals (PRS) and transmitting PRS on the determined set of time-frequency resources. The user equipment (UE) may randomly select the at least one parameter used to determine the set of time-frequency resources to measure for the PRS from the BS and measure PRS on the determined set of time-frequency resources.

Abstract: A user equipment (UE) configured for position determination receives positioning assistance data from a location server that is positioning method specific and provides information related to the prioritization of one or more of frequency layers, transmission points (TRPs), Positioning Reference Signal (PRS) resource sets, and PRS resources or a combination thereof. The positioning assistance data may be generated by the location server in response to the UE measurement capabilities. The UE determines a prioritization for PRS measurements based at least on one or more orderings of the information for the frequency layers, the TRPs, the PRS resource sets, or the PRS resources in the positioning assistance data, or a combination thereof and the positioning method. Downlink PRS are measured by the UE based on the prioritization.
