Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a random access channel (RACH) signature from among one or more RACH signatures associated with a synchronization signal block (SSB). The UE may transmit, to a base station (BS), a RACH communication using the selected RACH signature. Numerous other aspects are provided.

Abstract: Monostatic radar with progressive length transmission may be used with half-duplex systems or with full-duplex systems to reduce self-interference. The system transmits a first signal for a first duration and receives a first reflection of the first signal from a first object during a second duration. The system transmits a second signal for a third duration longer than the first duration and receives a second reflection of the second signal from a second object during a fourth duration. The system calculates a position of the first object and the second object based on the first reflection and the second reflection. The first signal, first duration, and second duration are configured to detect reflections from objects within a first distance of the system. The second signal, third duration, and fourth duration are configured to detect reflections from objects between the first distance and a second distance from the system.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information reference signal (CSI-RS) for multiple beam transmissions. In an example, a first CSI-RS triggering state of one or more CSI-RS triggering states indicates a CSI-RS resource set and associated transmission configuration indication (TCI) states. The CSI-RS resource set includes a plurality of CSI-RS resources. Each CSI-RS resource of the plurality of CSI-RS resources is associated with one or more corresponding TCI states as indicated by the first CSI-RS triggering state. A first CSI-RS resource of the plurality of CSI-RS resources is associated with a first plurality of TCI states as indicated by the first CSI-RS triggering state.

Abstract: Aspects described herein relate to resource block allocation for time domain single-carrier waveform processing in new radio (NR). Specifically, in an aspect, a guard band may be allocated for a single-carrier waveform in a time or frequency domain. In another aspect, a resource block may be allocated for a time domain single-carrier waveform.

Abstract: Disclosed are techniques for environment sensing. In an aspect, a transmitter base station determines a configuration for a radio frequency (RF) sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, and transmits the RF sensing signal to at least one receiver base station based on the configuration. In an aspect, a receiver base station receives a configuration for an RF sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, receives, from at least one transmitter base station, the RF sensing signal, and detects at least one target object based, at least in part, on reception of the RF sensing signal.

Abstract: Disclosed are techniques for allocating resources for environment sensing. In an aspect, a base station transmits a first radar reference signal (RRS) on a first set of resources comprising first time resources, first frequency resources, first spatial resources, or any combination thereof, wherein the first set of resources is selected to enable a first user equipment (UE) to perform a first type of environment sensing, and transmits a second RRS on a second set of resources comprising second time resources, second frequency resources, second spatial resources, or any combination thereof, wherein the second set of resources is selected to enable a second UE to perform a second type of environment sensing, wherein the second set of resources is different from the first set of resources, and wherein the second type of environment sensing is different from the first type of environment sensing.

Abstract: Bi-static radio-based object location detection can include determining, by a wireless device, a location of a remote wireless device; obtaining a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determining a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA. In another example, a wireless device includes a wireless transceiver; a non-transitory computer-readable medium; and a processor communicatively coupled to the wireless transceiver and non-transitory computer-readable medium, the processor configured to determine a location of a remote wireless device; obtain a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determine a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA.

Abstract: A method of wireless communication by a base station detects a UE is in a high speed train scenario. The method also instructs the UE to enter a high speed train (HST) mode when the UE is detected to be in the high speed train scenario. The method further performs beam management in accordance with the HST mode. A UE (user equipment) for wireless communication detects when the UE is in high speed train scenario. The UE also reports the high speed train scenario to a base station and then receives instructions from the base station to enter a high speed train (HST) mode. The UE performs beam management in accordance with the HST mode.
