Abstract: Certain aspects of the present disclosure provide techniques for adaptive node activation and configuration in cooperative sensing. A method that may be performed by a sensing management function (SnMF) entity includes receiving a first radio frequency (RF) sensing request, from a first entity, for scanning an environment to detect at least a first object, initiating a first RF sensing session in the environment in response to the first RF sensing request, receiving a second RF sensing request, from a second entity, for scanning the environment to detect at least a second object during the first RF sensing session, accommodating the second RF sensing request using output from the first RF sensing session, wherein the first RF sensing session is ongoing, detecting the first and second objects in the environment, and transmitting information about the detected first and second object to the first and second entity, respectively.

Abstract: Methods, systems, and devices for time domain single carrier (SC) waveform communications are described. A user equipment (UE) may generate an SC waveform by resampling (e.g., up-sampling) mapped information bits prior to insertion of a cyclic prefix (CP) or guard interval (GI). Performing resampling prior to CP/GI insertion allows for resource allocation flexibility and a base station may allocate resources for the SC waveform in accordance with this flexibility. For example, a base station may not be limited or restricted to a certain number of resources for SC waveform communications and may therefore determine a resource allocation for the UE based on the capability of the UE to perform resampling prior to CP/GI insertion. The resampling may be performed according to a set of parameters including a resampling ratio, which may be indicated to the UE via control signaling (e.g., from the base station).

In some aspects, a user equipment (UE) may detect a synchronization signal block (SSB) within a discovery reference signal (DRS) transmission window that includes more than 64 candidate SSB positions; determine an index value of the SSB based at least in part on an indexing scheme for SSBs that are included in the DRS transmission window, wherein the indexing scheme includes one of a consecutive indexing scheme or a non-consecutive indexing scheme; and determine a cell timing based at least in part on the index value. Numerous other aspects are described.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may determine a plurality of measurement gap (MG) configurations, each MG configuration defining one or more MGs. The UE may send, to a serving base station, a request to use a first MG configuration from the plurality of MG configurations, and may receive a response to the first request. The UE then measures positioning signals using an MG configuration indicated by the response. Based on measurements of the first set of positioning signals, the UE may select a second MG configuration, send a second request to use the second MG configuration, and receive a response to the second request. The UE then measures a second set of positioning signals using an MG configuration indicated by the response to the second request.

Abstract: A method, an apparatus, a base station, and a user equipment (UE) for wireless communication are provided to reduce the retransmission latency for URLLC communications. Upon receiving a downlink data transmission, a UE waits until it completes decoding of the received downlink data transmission before it can send an ACK/NAK report on the decoded downlink data transmission. In case of a decoding failure, the base station cannot start retransmission until the UE finishes the decoding of the downlink data transmission and sends the ACK/NAK report and until the base station finishes decoding of an NAK in the ACK/NAK report. This considerable retransmission latency may not meet stringent latency requirements of some URLLC applications. A two-stage ACK/NAK reporting is disclosed to reduce the retransmission latency where the UE sends an early ACK/NAK report upon partially completing the decoding of the downlink data transmission.

Abstract: Wireless communications systems and methods related to providing frequency diversity for communications in an unlicensed spectrum are provided. A first wireless communication device communicates, with a second wireless communication device, an opportunistic frequency-switching configuration for a first frequency band and a second frequency band. The first frequency band and the second frequency band are shared by a first network operating entity and a second network operating entity. The first wireless communication device communicates, with the second wireless communication device, a first communication signal in a first frequency band based on the opportunistic frequency-switching configuration. The first wireless communication device switches from the first frequency band to a second frequency band based on the opportunistic frequency-switching configuration. The first wireless communication device communicates, with the second wireless communication device after the switching, a second communication signal in the second frequency band based on the opportunistic frequency-switching configuration.
