摘要： Disclosed are techniques for handling an overlap between a higher priority channel and a lower priority channel. In an aspect, a transmitter node detects an overlap between an allocation of a first set of resources of a wireless communication link for transmission of the lower priority channel and an allocation of a second set of resources of the wireless communication link for transmission of the higher priority channel, removes a subset of resources from the first set of resources to generate a removed subset of resources of the first set of resources and a remaining subset of resources of the first set of resources, and transmits, to a receiver node, the lower priority channel on the remaining subset of resources, wherein the higher priority channel is transmitted on the removed subset of resources, wherein the higher priority channel or the lower priority channel is a positioning reference signal.

摘要： Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) identifies a set of positioning sources, each positioning source comprising a positioning reference signal (PRS) resource, a PRS resource set, a PRS frequency layer, and/or a transmission/reception point (TRP). From the set of positioning sources, the UE identifies a consistency group comprising a collection of positioning sources grouped based on expected values of at least one metric of a reference signal from each positioning source, measured values of the at least one metric for the reference signal from each positioning source, and an error threshold. The UE identifies one or more subsets of positioning sources within the consistency group, each subset having at least one metric error value. The UE reports, to a network entity, information about the consistency group and information about at least one of the subsets of positioning sources within the consistency group.

摘要： In an aspect, a first base station (e.g., Rx gNB) receives, from a radar controller, a configuration of UL T-F resources for the first base station to receive at least one radar signal from a second base station. The first base station further determines power control parameter(s) associated with the at least one radar signal, at least one UL transmission, or a combination thereof. The first base station performs, based on the power control parameter(s), action(s) to mitigate impact by the at least one radar signal to the at least one UL transmission, or by the at least one UL transmission to the at least one radar signal, or a combination thereof. The first base station measures the at least one radar signal on the set of UL T-F resources in accordance with the configuration.

摘要： Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) reports, to a network entity, a minimum number of symbols of a positioning reference signal (PRS) resource of a first transmission-reception point (TRP) of a pair of TRPs based on a reference signal time difference (RSTD) uncertainty parameter for the pair of TRPs, wherein the minimum number of symbols is less than a total number of symbols allocated for the PRS resource, and performs a positioning measurement of the minimum number of symbols of the PRS resource.

摘要： A method of measuring a wireless OFDM PRS at a user equipment includes: selecting a symbol subset of a symbol group of the OFDM PRS, the OFDM PRS comprising a slot of symbols comprising the symbol group, the symbol group consisting of a first symbol quantity of consecutive ones of the symbols, the symbol group being fully staggered in frequency domain, the symbol subset consisting of a second symbol quantity of the symbols of the symbol group, the second symbol quantity being smaller than the first symbol quantity, and the symbol subset being less than fully staggered in the frequency domain; and measuring the symbol subset without measuring all of the symbols of the symbol group.

摘要： Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a network entity, a request to provide an enhanced positioning measurement report comprising a positioning measurement and further comprising a report of components of a channel power delay profile (PDP), a report of a probability distribution of times of arrival (ToA), or both. The UE may determine an enhanced measurement period required by the UE to perform the enhanced positioning measurement, wherein the enhanced measurement period is longer than a standard measurement period required by the UE to perform a non-enhanced positioning measurement. The UE may perform the enhanced positioning measurement using the enhanced measurement period. The UE may provide the enhanced positioning measurement report to the network entity.

摘要： Techniques are provided for operating user equipment (UE) in a discontinuous reception (DRX) mode, and more specifically, setting a DRX inactivity timer value. An example method for operating a user equipment in a discontinuous reception mode including an active mode for communicating with a network and an inactive mode when the user equipment does not communicate with the network includes determining a trigger condition based on a communication with the network, determining the inactivity timer value based on the trigger condition, and operating the user equipment in the active mode during a duration of the inactivity timer value and in the inactive mode after the duration of the inactivity timer value.

摘要： In an embodiment, a UE transmits an on-demand PRS request for PRS(s) on selected frequency-domain resource(s) (e.g., frequency layer, frequency band, CC, etc.). In another embodiment, a UE receives, from a network component (e.g., BS, core network component, LMF, location server, etc.), configuration of frequency-domain resources (e.g., frequency layer, frequency band, CC, etc.), wherein each frequency-domain resource configuration is associated with a bandwidth and SCS. The UE further receives, from the network component, configuration of PRS(s), wherein each PRS is associated with a single frequency-domain resource from the frequency-domain resources. The UE determines a single reference TRP for each of the frequency-domain resources, performs PRS measurements on the PRS(s), and determines positioning measurements at least based on the PRS measurements and the determined reference TRPs.

摘要： In an embodiment, a UE determines a maximum duration to which a UE shall remain active after a DRX ON period to transmit and/or process one or more reference signals for positioning associated with a positioning session. The UE transmits an indication of the maximum value to a BS. The UE and the BS each selectively transmit and/or process the one or more reference signals (e.g., DL PRSs and/or UL SRS-Ps) based at least in part upon the maximum duration.

摘要： A method of providing positioning state information in a channel usable for conveying the positioning state information includes: obtaining a positioning state information resource allocation parameter; determining a positioning resource amount based on the positioning state information resource allocation parameter, the positioning resource amount being an amount of resources of the channel usable for conveying the positioning state information; and transmitting the positioning state information over the channel while occupying no more than the positioning resource amount of resources of the channel.
