Abstract: 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.

Abstract: Sounding reference signals (SRS) transmitted by a UE, e.g., for positioning or channel estimation, may be configured for one or both of frequency tone level cyclic shift and symbol level code, which, for example, enables multiplexing a greater number of UEs. The frequency tone level cyclic shift is produced by jointly processing a number of symbols with an extended cyclic shift structure. The SRS may be configured using a symbol group level that indicates the number of symbols associated with a cyclic shift structure, and an outer code that indicates a multiplier applied to the SRS at the symbol level, which increases the multiplexing opportunities. The symbol level code may further indicate an extended cyclic shift indicating a linear increase in phase rotation across tones in symbols associated with the symbol group level.

Abstract: Disclosed are techniques for radio frequency (RF) sensing. In an aspect, a network entity, such as a base station, may identify an opportunity for RF sensing during which a user equipment (UE) does not transmit signals, the opportunity comprising a guard period of the UE, a bandwidth part (BWP) switching period of the UE, or a beam switching period of the UE. The network entity may transmit an RF sensing signal, receive an RF sensing signal, or both, during the opportunity for RF sensing. In an aspect, a UE may determine an opportunity for a network entity to perform RF sensing while the UE does not transmit signals, the opportunity comprising a guard period of the UE, a BWP switching period of the UE, or a beam switching period of the UE. The UE may indicate, to the network entity, the opportunity for RF sensing.

Abstract: This disclosure provides methods, devices and systems for channel sounding for wireless communications. Some implementations more specifically relate to scheduling sounding reference signal (SRS) resource sets for wireless devices having more than 4 receive (RX) antenna ports. In some implementations, a base station may determine an antenna switching capability of a user equipment (UE). The antenna switching capability indicates a number of RX antenna ports of the UE. The base station schedules a number of SRS resource sets for the UE based at least in part on the number of RX antenna ports in excess of four. For example, the number of RX antenna ports may be equal to 8. As another example, the number of RX antenna ports may be equal to 6. The base station further receives, from the UE, uplink transmissions of one or more SRS resources for each of the scheduled SRS resource sets.
