Abstract: Methods, systems, and devices for wireless communications are described. A receiving device (e.g., a sidelink user equipment (UE), such as a first UE) may receive sidelink communications from a second UE via a sidelink channel. The receiving device may transmit a feedback message to the second UE via a sidelink feedback channel using a first resource configuration, the feedback message based at least in part on the sidelink communications. The receiving device may identify a second resource configuration of the sidelink feedback channel associated with sidelink communications via the sidelink feedback channel. The receiving device may perform the sidelink communications with the second UE via the sidelink feedback channel using the second resource configuration of the sidelink feedback channel.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support the transmission of a scheduling request via a physical sidelink feedback channel (PSFCH). In some cases, a user equipment (UE) may determine a configuration of a set of PSFCH resource blocks (RBs). The UE may receive a first bit map that may indicate a subset of the set of PSFCH RBs allocated for transmitting a scheduling request on the PSFCH, and the UE may receive a second bit map that may indicate a second subset of the PSFCH RBs allocated for hybrid automatic repeat request (HARQ) messages. The UE may transmit a scheduling request via one or more RBs of the first subset of the PSFCH RBs. In some cases, the UE may generate a waveform for transmitting the scheduling request message, and the waveform may be based on the number of RBs selected.

Abstract: Certain aspects of the present disclosure provide techniques for using timing synchronization signals (TSSs) and frequency synchronization signals (FSSs). An example method, performed at a wireless node, includes performing timing synchronization based on a first synchronization signal (SS), performing frequency synchronization based on a second SS, and communicating after performing the timing synchronization and the frequency synchronization.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a radio frequency identification (RFID) device receives, from an RFID tag, a first backscattered signal, receives, from the RFID tag, a second backscattered signal having a known time offset relative to the first backscattered signal, and performs interference cancellation on the first backscattered signal based on the second backscattered signal.

Abstract: Disclosed are techniques for wireless communication. In an aspect, radio frequency identification (RFID) device may receive a positioning reference signal that is transmitted over a set of radio resources of a wireless communications network, the positioning reference signal including a first temporal portion for energy harvesting and a second temporal portion for backscattering. The RFID device may transmit a backscattered signal based on at least a part of the second temporal portion of the positioning reference signal.

Abstract: Aspects of the disclosure are directed to an apparatus configured for wireless communication. The apparatus may include any wireless communication device configured for radio frequency identification (RFID) communications. In some examples, the apparatus includes a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the one or more processors are configured to cause the apparatus to obtain a first signal from a radio frequency identifier (RFID) device. In some examples, the one or more processors are configured to cause the apparatus to output, for transmission to the RFID device in response to the first signal, a first backscatter signal configured to indicate a beamforming capability of the apparatus.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, scheduling information scheduling one or more communications. The one or more communications may be scheduled over one or more of a sidelink, an uplink, or a downlink. The scheduling information may provide one or more of a transmission parameter for the one or more communications or a reception parameter for the one or more communications. The UE may communicate the one or more communications based at least in part on the one or more of the transmission parameter or the reception parameter. Numerous other aspects are described.
