Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may determine an energy detection threshold of a reference bandwidth, the energy detection threshold being based on at least one of a transmit power or a power class. The apparatus may also measure an interference level of at least one signal. Additionally, the apparatus may adjust the energy detection threshold of the reference bandwidth based on a sensing bandwidth. The apparatus may also determine whether a transmission medium is available based on at least one of the adjusted energy detection threshold or the measured interference level of the at least one signal.

Abstract: Disclosed are systems, methods, and non-transitory media for providing signaling consideration for wireless positioning with disjoint bandwidth segments. For instance, one or more indications of a preferred bandwidth configuration can be transmitted by a user equipment. Based on the one or more indications, the user equipment can receive a positioning configuration that indicates disjoint bandwidth segments containing a positioning reference signal based on the preferred bandwidth configuration. In response, the user equipment can then determine one or more positioning measurements based on the positioning reference signal in the disjoint bandwidth segments.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that configures a measurement gap for the UE. The UE may perform a first measurement and a second measurement in the measurement gap, wherein the first measurement and the second measurement are different types of measurements. The UE may transmit measurement information based at least in part on the first measurement or the second measurement. Numerous other aspects are provided.

Abstract: Techniques are provided for managing transmit and receive beams in a millimeter wave (mmW) communication system for use in bistatic radio frequency (RF) sensing. An example method of tracking targets with bistatic radio frequency sensing includes receiving one or more sensing reference signals, generating a signal report based at least in part on the one or more sensing reference signals, transmitting the signal report, receiving tracking signal configuration information, receiving one or more tracking reference signals identified in the tracking signal configuration information, and tracking one or more targets associated with the one or more tracking reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a mapping between a set of synchronization signal block resources and a set of operating frequencies within a frequency band. The UE may identify a parameter of a synchronization signal block based on an operating frequency of the set of operating frequencies for conveying the synchronization signal block and a direction of a beam for conveying the synchronization signal block. The parameter may include an index of the synchronization signal block. The UE may monitor for the synchronization signal block based on the identified parameter.

Abstract: A user equipment (UE) transmits reference signals for positioning while in Idle or Inactive state. While in a connected state, the UE is preconfigured with Sounding Reference Signal (SRS) resource configuration including at least one of timing adjustment (TA) and an uplink (UL) transmission spatial filter. The UE transmits positioning SRS while in Idle or Inactive mode based on the preconfiguration. The TA and UL transmission spatial filter may be updated by a serving base station using control signals or a paging message received by the UE while in in Idle or Inactive mode. The validity of the TA and UL transmission spatial filter may be monitored using expiration timers or a relative position change threshold. The reference signals transmitted may be based on a UE may Physical Random Access Channel (PRACH), which is insensitive to TA changes. A long sequence PRACH may be used for improved positioning accuracy.
