Abstract: Wireless communications systems and methods related to LBT aware autonomous sidelink sensing are provided. A first UE determines, based on a projected listen-before-talk (LBT) completion time, at least one of a sensing window or a first resource selection window. The first UE senses, based on the determining, in a sidelink resource pool within a shared radio frequency band during the sensing window. The first UE identifies, based on the sensing, a subset of resources from the sidelink resource pool that are within the first resource selection window. The first UE selects at least a first resource from the subset of resources. The first UE transmits, to a second UE using the selected first resource, a sidelink transmission.

Abstract: Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between one or more sensors/actuators (SAs) and programmable logic controller (PLC) in internet of things (IoT) applications in order to minimize the number of subchannels that a receiver (e.g., PLC or SA) may need to blind decode. More particularly, the search space is configurable based on a hashing function that is based in part on a portion of the resources (e.g., PLC resources) that have been allocated or reserved for sidelink communication within the PLC subnetwork (or PLC group) from the sidelink resource pool available to a plurality of PLCs in a network. By limiting the search space to a subset of resources that are specific to the PLC subnetwork or group, the need for the SA or PLC to perform blind decoding of sidelink control information (SCI) may be further reduced.

Abstract: In an aspect, first and second UEs each detect a target associated with a deflection point for a transmission beam from a BS to the respective UE, and each transmit, to the BS, information associated with the target. The BS transmits STRS configuration information to the first and second UEs. The BS multicasts, to the first and second UEs, an STRS on the transmission beam in accordance with the STRS configuration information.

Abstract: Techniques are provided for single sided beam management 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 a scanning reference signal, generating a scanning signal report indicating one or more target groups associated with the scanning reference signal, transmitting the scanning signal report, receiving tracking signal configuration information indicating a tracking reference signal associated with the one or more target groups, receiving the tracking reference signal identified in the tracking signal configuration information, and tracking the one or more target groups associated with the tracking reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration of a resource pool for configured grant uplink communications and one or more parameters for identifying a resource set from the resource pool, wherein the resource set is a subset of resources in the resource pool; identify the resource set of the resource pool based at least in part on the one or more parameters; and transmit a configured grant uplink communication in a resource selected from the resource set. 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: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a sounding reference signal (SRS) resource configuration, the SRS resource configuration indicating at least a comb pattern for at least one SRS resource allocated to the UE and a puncturing unit for the comb pattern, wherein the comb pattern is divided into one or more puncturing units, wherein each puncturing unit comprises one or more time units of the comb pattern, and wherein each of the one or more time units comprises two or more symbols, and refrains from transmitting all SRS transmissions of the at least one SRS resource within a first puncturing unit of the one or more puncturing units based on a determination that one or more SRS transmissions of the at least one SRS resource within the first puncturing unit are to be dropped.

Abstract: A user equipment (UE) transmits reference signals for positioning while in Idle or Inactive state. While in a connected state, the UE is pre-configured 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 pre-configuration. 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.
