Abstract: Certain aspects provide a method for wireless communication by a first user-equipment (UE). The method generally includes determining a first configuration for communication with a second UE of one or more discovery messages on a sidelink channel and a second configuration for data communication with the second UE on the sidelink channel, wherein the first configuration is different than the second configuration, and communicating with the second UE in accordance with at least one of the first configuration or the second configuration.

Abstract: A network access node including a transceiver coupled to a sidelink receiver user equipment (UE) (or to a sidelink transmitter UE) is disclosed. The network access node may obtain a network access interface discontinuous reception (DRX) slot offset value (or a sidelink interface DRX slot offset value) corresponding to a shift in a network access interface DRX Active state start time (or a sidelink interface DRX Active state start time) of the receiver UE. The shift may configure an alignment of a sidelink interface DRX Active state start time (or the network access interface DRX Active state start time) with the network access interface DRX Active state start time (or the sidelink interface DRX Active state start time). The network access interface DRX (or sidelink interface DRX) slot offset value may be transmitted to the receiver UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, on a physical uplink channel, repetitions without a demodulation reference signal (DMRS). The UE may maintain continuity for joint channel estimation of the repetitions without a DMRS during a first time domain window that is based at least in part on a second time domain window associated with joint channel estimation for repetitions with a DMRS. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted by a base station. The UE may receive system information that includes reconfigurable intelligent surface (RIS) or repeater assisted initial access information that identifies a set of SSBs that are associated with an RIS or a repeater and a modulation signature associated with the RIS or the repeater. The UE may selectively perform initial access using the SSB or search for another SSB based at least in part on the RIS or repeater assisted initial access information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may receive, from a second device, a sounding reference signal (SRS) prior to a scheduled communication. The first device may transmit, to the second device, an indication that a measurement of the SRS does not satisfy a threshold, if the measurement of the SRS does not satisfy the threshold. The first device may activate, based at least in part on the transmitting the indication and before the scheduled communication, a multi-point communication mode. Numerous other aspects are described.

Abstract: Aspects relate to techniques for communication between wireless communication devices using ranging channel information obtained by each of the wireless communication devices. For example, a first wireless communication device may obtain first monostatic ranging channel information based on reflected ranging signals received in response to transmission of a ranging signal. In addition, the first wireless communication device may receive ranging feedback information from a second wireless communication device associated with second monostatic ranging channel information obtained by the second wireless communication device. The first wireless communication device may then determine bistatic channel information from the first monostatic ranging channel information and the ranging feedback information and transmit a message to the second wireless communication device based on the bistatic channel information.

Abstract: Aspects presented herein may enable a wireless device to perform an SL ranging based on a single-sided PRS transmission. In one aspect, a first wireless device transmits one or more reference signals to at least one RIS associated with a second wireless device. The first wireless device receives one or more reflected reference signals reflected from the at least one RIS. The first wireless device calculates a signal RTT based on the one or more reference signals and the one or more reflected reference signals. In another aspect, a second wireless device transmits, to a first wireless device, information indicating a time, a duration, or a periodicity in which at least one RIS associated with the second wireless device is to be activated. The second wireless device activate the at least one RIS based on the information.

Abstract: Aspects presented herein may enable one or more wireless devices to perform a sidelink-based ranging and/or positioning with an assistance of an RIS. In one aspect, a first wireless device receives an information indicating at least a time in which at least one RIS is to be activated. The first wireless device transmits a first set of reference signals to a second wireless device via the at least one RIS. The first wireless receives a second set of reference signals transmitted from the second wireless device via the at least one RIS. The first wireless calculates a first signal RTT based on the first set of reference signals and the second set of reference signals.
