Abstract: Disclosed are techniques for wireless positioning performed by a user equipment. For example, the method includes entering into a Radio Resource Control (RRC) inactive state. The method includes monitoring, during a first time interval, while the user equipment is in the RRC inactive state, one or more first bandwidth parts having a first bandwidth to perform a first operation. The method includes monitoring, during a second time interval, while the user equipment is in the RRC inactive state, one or more second bandwidth parts having a second bandwidth to perform a second operation. The second bandwidth is different than the second bandwidth.

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: Certain aspects of the present disclosure provide techniques for securing physical (PHY) layer communications. Certain aspects relate to a method for wireless communication by a user equipment (UE). In some examples, the method includes receiving, from a wireless communication device, an indication of a mode of a plurality of modes for use for secure communication over a physical (PHY) channel, wherein each of the plurality of modes is associated with one or more of: one or more types of signals to secure using one or more secret keys; or one or more techniques to secure communication using the one or more secret keys. In some examples, the method includes communicating over the PHY channel in accordance with the mode.

Abstract: Aspects presented herein may enable an RF sensing node to transmit RF sensing signals based on OFDM symbols that may be flexibly configured, such that OFDM symbols used for RF sensing may be different from OFDM symbols used for communications. In one aspect, an RF sensing node transmits an RF sensing signal in a first time duration of a symbol in an RF sensing session. The RF sensing node monitors for a reflected RS sensing signal in a second time duration of the symbol that does not overlap with the first time duration, the symbol including a CP that does not overlap with the first time duration and the second time duration.

Abstract: Disclosed are techniques for positioning. In an aspect, a network entity receives, from a first base station of a user equipment (UE) operating in a radio resource control (RRC) inactive state, an event report message indicating that the UE has received a request to perform a positioning procedure, and transmits, based on a determination that the UE would benefit from updated positioning assistance data for the positioning procedure, the updated positioning assistance data to a second base station of the UE to enable the second base station to send the updated positioning assistance data to the UE.

Abstract: A user equipment (UE) may be configured to transmit sounding reference signals to sound over ports of a channel. The UE may be configured to receive a message to trigger transmission of at least one sounding reference signal (SRS) of at least one SRS resource set for sounding over an active bandwidth part (BWP) in an upcoming slot, the upcoming slot being offset by a number of available slots from a reference slot indicated by the message. The UE may be further configured to detect a gap in which operation for the active BWP is suspended occurring before the transmission of the at least one SRS of the at least one SRS resource set is complete.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE receives, from a position estimation entity, a parent PRS resource set configuration associated with a set of parent beams from a TRP, and a set of child PRS resource set configurations associated with a respective set of child beams for each of the set of parent beams. The UE performs measurements on the set of parent beams and at least one activated set of child beams. The position estimation entity receives at least one measurement report(s) based on measurements associated with the set of parent beams and the at least one activated set of child beams.
