Abstract: A method for wireless communication by a user equipment (UE) includes transmitting a first message indicating whether a first neighbor cell measurement is supported without a first measurement gap, when the first neighbor cell and/or a serving cell comprise a non-terrestrial network (NTN) cell. The method also includes receiving a measurement gap configuration for the first neighbor cell measurement, based on the first message indicating the first neighbor cell measurement is supported with a measurement gap.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a method of wireless communication performed by a user equipment (UE) includes receiving positioning reference signal (PRS) configuration information for PRS signals transmitted by at least one transmission/reception point (TRP), the PRS configuration information comprising beam information associated with the PRS signals. The method also includes determining a subset of the PRS signals based at least on the beam information associated with the PRS signals. The method also includes monitoring the subset of the PRS signals and not monitoring PRS signals not in the subset. The UE may save power by monitoring the relevant subset of the PRS signals and by not monitoring PRS signals not in the subset. The techniques may be applied to TRPs in a terrestrial network, TRPs a non-terrestrial network, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information indicating a condition for a conditional handover, and an indication to communicate on a source cell after transmitting a message on a target cell, associated with the conditional handover, and before receiving an additional message on the target cell. The UE may transmit the message on the target cell responsive to the condition for the conditional handover being satisfied. Numerous other aspects are described.

Abstract: A first UE may obtain at least one parameter associated with an Rx timing of one or more CLI measurement resources. The one or more CLI measurement resources may be associated with CLI between the first UE and at least one second UE. The first UE may further refrain from receiving one or more serving DL channels or resources from a network node during the Rx timing based on the at least one parameter. The one or more serving DL channels or resources may overlap with at least one symbol of the one or more CLI measurement resources.

Abstract: Systems and techniques are provided for wireless communications at a network entity. For example, then systems and techniques can include determining, at the network entity, a transmission timing compensation between a first reference signal and a second reference signal. The first reference signal can be transmitted using a first communication link. The second reference signal can be transmitted based on an offset determined based on the transmission timing compensation, wherein the second reference signal is transmitted suing a second communication link. The offset can be used to offset transmission of the second reference signal from transmission of the first reference signal.

Abstract: Systems and techniques are provided for wireless communications performed at a network entity. For example, the systems and techniques can include obtaining, at the network entity, a target relative time difference (RTD). A transmission timing pre-compensation can be determined at the network entity between a first reference signal and a second reference signal, wherein the transmission timing pre-compensation is determined based on the target RTD and one or more network delay components. The first reference signal and the second reference signal can be transmitted using the transmission timing pre-compensation to offset the first reference signal from the second reference signal by the target RTD.

Abstract: Certain aspects of the present disclosure provide techniques for channel access using an intelligent reflecting surface (IRS). A method that may be performed by a network entity includes monitoring candidate paths for channel access, wherein the candidate paths include one or more paths through an intelligent reflecting surface; determining at least one path among the candidate paths for communications with a first wireless node based at least in part on one or more criteria associated with the candidate paths and obtained from monitoring the candidate paths; and communicating with the first wireless node via the at least one path.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication for applying resource element (RE) skipping to a symbol where a beam change is to occur. A transmitter and a receiver determine that a beam change is to occur during the symbol. The transmitter allocates bits to a subset of REs for the symbol in a frequency domain allocation. Each RE of the subset is spaced apart by a number of empty REs. The transmitter performs an inverse fast Fourier transform (IFFT) on the REs to generate a time domain signal including a number of repetitions of a transmitted waveform. The receiver receives the time domain signal during at least a portion of the symbol. The receiver performs a fast Fourier transform (FFT) on the time domain signal and determines transmitted bits or a channel from the subset of REs output from the FFT.

Abstract: Disclosed are techniques for positioning. A receiver measures a time of arrival (ToA) of a positioning reference signal (PRS) transmission of a first PRS sequence transmitted by a first transmitter, measures a ToA of a PRS transmission of a second PRS sequence transmitted by a second transmitter, and determines an observed time difference of arrival (OTDOA) as a difference between the ToA of the PRS transmission of the first PRS sequence and the ToA of the PRS transmission of the second PRS sequence, wherein the OTDOA is less than half a maximum differential delay expected between the PRS transmission of the first PRS sequence and the PRS transmission of the second PRS sequence, and wherein a repetition duration of the first PRS sequence and the second PRS sequence is greater than 10 milliseconds (ms) and at least twice the maximum differential delay.
