Abstract: Methods, systems, and devices for wireless communication that support positioning techniques are described. One method may include receiving a positioning reference signal (PRS) configuration; receiving a plurality of PRS transmissions over a shared radio frequency spectrum from a plurality of base stations; and transmitting a measurement report of the PRS transmissions. The PRS transmissions may be received according to the PRS configuration. Another method may include receiving a discovery reference signal (DRS) transmission from a first base station; decoding a cell identifier of the first base station based on the DRS transmission; determining timing information of the first base station based on the DRS transmission; and transmitting a measurement report of the DRS transmission to a second base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a helper user equipment (UE) may receive, from a base station, a signaling message requesting the helper UE to monitor for and transmit a sidelink communication in a manner that uses a single-frequency network, wherein the sidelink communication is to be transmitted by a source UE to a destination UE that is different from the helper UE. The helper UE may receive the sidelink communication, transmitted by the source UE to the destination UE, in a first time-frequency resource of the single-frequency network. The helper UE may transmit the sidelink communication in a second time-frequency resource of the single-frequency network, wherein the second time-frequency resource is indicated to the helper UE by the base station. Numerous other aspects are described.

Abstract: Techniques for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling sidelink transmissions in one or more sets of multiple transmission time intervals (TTIs) over a shared spectrum. The UE may perform a listen-before-talk (LBT) for one or more of the TTIs in the one or more sets of multiple TTIs, and the UE may transmit, to a base station, an indication of results of the LBT performed for the one or more TTIs. Because the UE may provide the results of the LBT to the base station, the base station may be able to schedule sidelink transmissions from the UE based on the results of the LBT. As such, the UE may experience increased throughput in sidelink communications since the scheduling at the base station may be improved.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support a super slot configuration for new radio (NR) sidelink over millimeter wave (mmW) operating frequencies. In a first aspect, a method of wireless communication by a user equipment (UE) includes obtaining a sidelink resource pool configuration including configuration of one or more super slots, wherein each super slot includes a plurality of slots contiguous in a time domain The UE may select one or more sidelink resource slots for sidelink transmissions in a sidelink resource pool and transmit an enhanced sidelink control information (eSCI) message in a first slot of a first super slot, wherein the eSCI message indicates a reservation of slots corresponding to the one or more sidelink resource slots. The UE may then send the sidelink transmissions on at least one slot of the reserved slots. Other aspects and features are also claimed and described.

Abstract: Disclosed are systems and techniques for wireless communications. In one example, an apparatus for wireless communication at a first user equipment (UE) can send a first sidelink communication to a second UE using a first beam pair of a unicast link with the second UE, wherein the first beam pair includes a first transmission beam and a first reception beam. In some aspects, the apparatus can determine a fault associated with at least one of the first transmission beam and the first reception beam.

Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink slots without symbols for automatic gain control. One aspect provides a method for wireless communication by a user equipment, including receiving a first cyclic prefix of a first symbol within a slot at the user equipment. The method further includes configuring a first automatic gain control setting based on a received power in the first cyclic prefix of the first symbol, and receiving a data portion of the first symbol using the first automatic gain control setting.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may transmit, to a secondary user equipment (UE), a first grant to conditionally transmit one or more data messages over a first set of resources upon completion of a detection procedure. The detection procedure may include monitoring a second set of resources for over-the-air (OTA) signals transmitted by a primary UE pursuant to a second grant, where the first set of resources at least partially overlaps the second set of resources. The UE may monitor for the OTA signals from the primary UE, determine that one or more conditions for transmission of the one or more data messages have been satisfied, and transmit the one or more data messages over the first set of resources.

Abstract: Certain aspects of the present disclosure provide a user equipment (UE) that may receive an indication of a proximity discovery resource in a physical sidelink feedback channel (PSFCH) symbol from a network entity. The UE may transmit a proximity discovery request including the indication of the proximity discovery resource. The UE may receive a PSFCH sequence associated with the proximity discovery resource from other UEs that may respond to the proximity discovery request. The UE may transmit a bit map sequence indicative of the other UEs to the network entity. The network entity may determine a proximity between the UE and the other UEs based on the bit map sequence. The network entity may schedule the UE and the other UEs based on the proximity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may attempt to receive one or more random access channel (RACH) messages from one or more user equipment (UEs); and transmit, based at least in part on the determination of a completion of processing of any received RACH messages of the one or more RACH messages, an early termination message to a UE to terminate a random access response window. In some aspects, a UE may transmit another RACH message as a response to receiving the early termination message. Numerous other aspects are provided.
