    摘要： Techniques for indicating a type of non-line-of-sight (NLOS) wireless signal path in a wireless communication network are described. In some embodiments, a method thereof may include receiving a plurality of reference signals, the plurality of reference signals originating from a respective plurality of wireless network nodes; determining at least one NLOS wireless signal path based on the plurality of reference signals; determining whether or not the at least one NLOS wireless signal path is introduced by a repeater of the wireless communication network based at least on a presence or an absence of a commonality among the plurality of reference signals; and indicating to a network entity whether the at least one NLOS wireless signal path is introduced by the repeater or not.

    摘要： Disclosed are techniques for wireless sensing. In an aspect, a method for reconfigurable intelligent surface (RIS)-assisted sensing performed by a base station (BS) includes configuring one or more reciprocal RIS beam pairs for sensing, wherein each of the one or more reciprocal RIS beam pairs comprises a downlink (DL) beam having a DL angle of departure (DL AoD) from a RIS controlled by a first set of control voltages and an uplink (UL) beam having an UL AoD from the RIS controlled by a second set of control voltages. The BS may send, to the RIS, information identifying the one or more reciprocal RIS beam pairs. The BS may perform monostatic sensing using at least one of the one or more reciprocal RIS beam pairs.

    摘要： Certain aspects of the present disclosure provide techniques for random access. A method for wireless communications by a user equipment (UE) includes determining a first timing advance (TA) for transmitting a random access channel (RACH) preamble. The method includes determining a second TA, different than the first TA, for transmitting the RACH preamble. The method includes transmitting the RACH preamble using the second TA. The method includes receiving a random access response (RAR) message including a timing advance command (TAC) and determining whether the RAR is intended for the UE based on the TAC, the first TA, and the second TA. The method includes transmitting a physical uplink shared channel (PUSCH) transmission based on a determination that the RAR is intended for the UE.
