Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a configuration of a retransmission of a first message of a random access procedure based on a set of transmission configuration options transmitted by a base station. For example, the UE may transmit the first message but may reconfigure the first message for the retransmission based on the transmission configuration options. Additionally, the UE may configure a set of transmission configuration states based on the transmission configuration options for transmitting/retransmitting the first message. In some cases, the UE may determine to switch transmission configuration states based on a trigger signaled by the base station and/or a determination by the UE. Additionally, the UE may transmit an indication of a log of state transitions performed prior to a retransmission of the first message to facilitate combining of the retransmissions at the base station.

Abstract: Methods of reducing the interferences of radar signals with uplink or downlink data communication signals in a wireless system for both data communication and radar sensing may include configuring the transmitters of the radar signals and the data communication signals such that the data communication signals and the radar signals are transmitted using different radio frequency resources, and/or configuring the receivers of the data communication signals to receive the data communication signals using a receive beam that does not collide with radar beams. The methods may also include using a reference signal for both downlink data communication and radar sensing and/or determining a Quasi-Colocation (QCL) configuration for downlink data reception based on information regarding a radar beam.

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: Certain aspects of the present disclosure provide techniques for scheduling and bandwidth part (BWP) adaptation for extended reality (XR). A method that may be performed by a user equipment (UE) includes obtaining an indication to change at least one of a minimum control-channel-to-data-channel delay or a bandwidth for receiving a first transmission on a BWP; changing the at least one of the minimum control-channel-to-data-channel delay to a new minimum control-channel-to-data-channel delay or the bandwidth on the BWP to a new bandwidth; and receiving the first transmission on the BWP using the at least one of the new minimum control-channel-to-data-channel delay or the new bandwidth of the BWP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station (BS), a signaling communication that indicates one or more preamble sequence configurations. Each of the preamble sequence configurations may specify a respective plurality of preamble sequence rules for a different random access channel (RACH) procedure type. The UE may generate, based at least in part on a plurality of preamble sequence rules for a preamble sequence configuration of the one or more preamble sequence configurations, a preamble sequence for a RACH communication in a RACH procedure. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method may be performed by a wireless device such as a user equipment (UE) and generally includes: receiving at least one downlink (DL) signal from one or more base stations or transmitting at least one uplink (UL) positioning reference signal (PRS), the received at least one DL signal comprising: at least one DL PRS, at least one synchronization signal block (SSB), at least one system information block (SIB), at least one other reference signal comprising a channel state information reference signal (CSI-RS), or a combination thereof, wherein at least one measurement is performed based, at least in part, on the received at least one DL signal or the transmitted at least one UL PRS; and performing at least one adjustment for random access based, at least in part, on the at least one measurement.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that favors the usage of resources for pilot signals and channel estimation in the transition slots of a slot burst, and the transmission of data in the subsequent slots of the slot burst. A device such as a user equipment (UE) and/or a base station may determine that the UE is operating in a transition state. The device may adapt a first numerology including a first number of symbols per slot used for transmission in the transition slots during the transition state, to a second scaled numerology including a second number of symbols per slot used for transmission in the subsequent slots after the transition state. A ratio of reference signal symbols to data symbol symbols may be greater in the transition slots than in the subsequent slots.
