Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a user equipment (UE) may identify, for a set of time periods associated with a reference signal associated with a physical downlink shared channel, an overlap between a first set of frequency resources allocated for the reference signal and a second set of frequency resources that are scheduled to puncture the first set of resources and that are unavailable for scheduling on the physical downlink shared channel. The UE may determine a remaining set of frequency resources from the first set of frequency resources based on the overlap, and a subset of frequency resources from the remaining set of frequency resources based on a reference signal processing configuration. The UE may then process the reference signal in the subset of frequency resources based on the reference signal processing configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station and based at least in part on a triggering event, an indication of a frequency domain indexing configuration for a relative reference point. The user equipment may use at least one of a start of a control resource set or an absolute reference point for the relative reference point based at least in part on the indication of the frequency domain indexing configuration. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for configuring reference signals. A method that may be performed by a user equipment (UE) includes receiving a control message indicating a first quasi co-location (QCL) for an aperiodic-tracking reference signal (A-TRS), the A-TRS being associated with a periodic-tracking reference signal (P-TRS), determining a second QCL for the P-TRS based on the first QCL for the A-TRS, setting a receive beam for reception of the P-TRS based on the second QCL of the P-TRS, and decoding one or more frames based on channel statistics estimated via the P-TRS received via the receive beam.

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: Disclosed are techniques for positioning a user equipment (UE). In aspects, a listening node determines a first time of arrival (ToA) at the listening node of a first radio frequency (RF) signal sent by a transmission-reception point (TRP) to the UE, determines a second ToA at the listening node of a second RF signal sent by the UE to the TRP, determines a time difference between the first ToA and the second ToA, and enables a positioning entity to estimate a location of the UE based on the time difference. The positioning entity calculates a distance between the listening node and the UE based on the time difference, a propagation time between the TRP and the listening node, a propagation time between the TRP and the UE, and a time difference between a ToA of the first RF signal at the UE and a transmission time of the second RF signal.

Abstract: Methods, systems, and devices for wireless communications are described that identify a minimum gap between a control channel transmission on a first component carrier (CC) that triggers a measurement report and an associated reference signal transmission on a second CC. The minimum gap may be based on a resource associated with a control channel transmission and a resource associated with the reference signal transmission. The first CC and the second CC have different numerologies and the minimum gap may be identified in terms of a number of OFDM symbols of the second CC that carries the reference signal transmission. The minimum gap also may be identified based on a location of the control channel transmission within a slot of the first CC. In cases where beam switching is used, the minimum gap may be further based at least in part on a beam switch time for performing the beam switching.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing remote interference using a previously detected relationship between an aggressor base station and a victim base station. The described techniques provide for allocating reference signal sequences for various victim base stations to send to an aggressor base station. The victim base station may trigger the aggressor base station to perform reference signal monitoring based on the previously detected victim-aggressor relationship, and may transmit a reference signal carrying a unique identifier based on the triggering. The first base station may send a request that the second base station to transmit a reference signal for enabling the first base station to measure interference of a wireless channel, and performing interference mitigation techniques at the first base station, the second base station, or both, to mitigate the remote interference.

Abstract: Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx−Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.
