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: In embodiments of systems and methods for managing communication between a wireless device and a base station, a base station may transmit Remaining Minimum System Information (RMSI) Downlink Control Information (DCI) indicating time and frequency resources for RMSI. A wireless device may receive a Channel State Indicator-Reference Signal (CSI-RS) based on the time and frequency resources for RMSI and may select a sub-beam of a beam associated with a synchronization signal block (SSB). The wireless device may send to the base station an indication of the selected sub-beam associated with the SSB in a Physical Random Access Channel (PRACH) message. The base station and the wireless device each may then perform an initial access procedure using the selected sub-beam to enable the wireless device to establish a communication link with the base station.

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: Techniques and apparatus for sharing hybrid automatic repeat request (HARQ) processes across component carriers (CCs) are described. An example technique involves identifying a carrier aggregation (CA) configuration in which at least a first CC of a plurality of CCs is aggregated with at least a second CC of the plurality of CCs. A HARQ configuration indicating a pool of HARQ processes shared by at least the first CC and the second CC is received from a base station (BS). Communications are performed with the BS on at least one of the first CC or the second CC, based at least in part on the HARQ configuration.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a minimum slot offset based at least in part on a determination of a minimum wake-up signal (WUS) gap capability associated with the UE, wherein the minimum WUS gap capability corresponds to a capability of the UE to support a WUS gap having a minimum gap size, wherein the minimum slot offset indicates a minimum time period between a physical downlink control channel (PDCCH) occasion and a physical downlink shared channel (PDSCH) occasion scheduled by the PDCCH; and monitor the PDCCH occasion for a downlink grant based at least in part on the configuration. Numerous other aspects are provided.

Abstract: A method of wireless communication receives multiple beams from a base station. The method also simultaneously reports a signal to interference plus noise ratio (SINR) for multiple beams with a single channel measurement resource (CMR) and a single interference measurement resource (IMR). The single IMR is configured for multiple interference sources. A method of wireless communication by a base station configures a UE with a group of interference sources. The base station also configures the UE with an interference measurement resource associated with the group of interference sources.
