Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine, when using resource spread multiple access with non-orthogonal multiple access, that a particular modulation scheme is enabled. The user equipment may process symbols using a set of processing sequences selected based at least in part on the particular modulation scheme such that the particular modulation scheme is preserved for the symbols. The user equipment may transmit the symbols based at least in part on processing the symbols using the set of processing sequences. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine information that identifies a resource for transmitting an acknowledgment of a message associated with a random access procedure. The information that identifies the resource may be determined based at least in part on at least one of: a frequency band associated with the random access procedure, a resource associated with at least one message in a sequence of messages associated with the random access procedure, a payload of at least one message in the sequence of messages associated with the random access procedure, or a grant associated with another message in the sequence of messages associated with the random access procedure. In some aspects, the user equipment may transmit the acknowledgment based at least in part on the information that identifies the resource. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure describe a guard band signal for communication on a guard band between a first frequency band utilized by a first radio access technology having a first sub-carrier spacing and a second frequency band utilized by a second radio access technology having a second sub-carrier spacing that is a multiple of the first sub-carrier spacing. The guard band signal includes a symbol that is repeated a number of times equal to the multiple. The guard band signal may be generated and transmitted by a transmitting device. The guard band signal may be received and decoded by a receiving device. The guard band signal is interpretable according to a first numerology of the first radio access technology and according to a second numerology of the second radio access technology.

Abstract: Aspects of the present disclosure provide systems, methods, and apparatuses for implementing the multiplexing of different orthogonal frequency-division multiplexing (OFDM) waveforms using a transmitter and receiver configured to process different types of signals without a need for distinct hardware structures. In one example, aspects of the present disclosure may include a transmitter configured to transmit both a first type of discrete fourier transform (DFT)-spread OFDM waveform and a second type of DFT-spread OFDM waveform that may be multiplexed over the wireless channel. In some aspects, the transmitter may modify the numerology of the zero-tail DFT-spread OFDM waveform to match the numerology of other OFDM waveforms (e.g., OFDM waveform with zero-guard or a single carrier DFT-spread OFDM with zero-guard).

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process may include receiving, at a network device (e.g., a user equipment (UE)) from a network entity via a number of sensing streams based on a maximum of Nt−J sensing streams, a waveform including communications resources and sensing resources. The waveform has a rank Nt and J is a number of layers scheduled for multiple-input multiple-output (MIMO) communications that is less than Nt. The process may further include processing at least the communications resources of the waveform.

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: In an aspect, a radar controller determines a radar slot format that configures transmission of a reference radar signal on a first symbol over a first link from a first base station to a second base station followed by at least one target radar signal on at least one second symbol over at least one second link from the first base station to the second base station, and transmits an indication of the radar slot format to the first base station and the second base station. The first base station transmits, and the second base station receives, the reference radar signal and the at least one target radar signal in accordance with the radar slot format.

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: Aspects described herein relate to configuring and selecting preamble and payload occasions for performing two-step random access procedures. Configurations on preamble occasions, payload occasions, association pattern between the occasions and synchronization signal block (SSB) beams, and the rules for selecting preamble and payload occasions for random access message transmission can be determined by the network and signaled to user equipment (UE). Based on the configurations and rules, UE can measure the link level quality and select possible preamble and payload occasions for one or more SSB beams achieving a threshold signal quality. Sets of one or more preamble occasions and one or more payload occasions can be further determined based on whether the preamble and payload occasion(s) can achieve a threshold transmission latency. The one or more preamble occasions and one or more payload occasions can be used to transmit random access messages in the two-step random access procedure.
