Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may receive, for communication in a network, information identifying a channel access frame structure, wherein the channel access frame structure is associated with a plurality of transmission time intervals (TTIs) grouped into a single frame, and wherein resources of the plurality of TTIs are allocated for transmission of reservation signal based at least in part on prioritization information. The transmitter device may transmit, to a receiver device, a reservation signal using a resource of the plurality of TTIs to indicate use of a subsequent resource for a subsequent transmission based at least in part on the channel access frame structure and a prioritization of the subsequent transmission. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to mechanisms to provide physical sidelink feedback channel (PSFCH) negotiation during sidelink connection establishment. A first UE may determine one or more conditions for PSFCH communications via the sidelink session(s) with the second UE. If the second UE accepts the conditions provided, the first and second UEs complete the sidelink connection. Further, while the first UE has a sidelink communication session with the second UE, a third UE may initiate another sidelink connection with the first UE. The first UE may compare the priority of the proposed sidelink connection with the priority of the ongoing sidelink communication session with the second UE. If the second UE's priority is greater, the first UE will maintain the second UE's status. If less, the first UE may engage in a renegotiation with second UE for the ongoing sidelink communication session to update their PSFCH conditions.

Abstract: Methods, systems, and devices for wireless communications are described. A device may determine a packet for transmission and determine whether to transmit a reservation signal prior to the transmission of the packet based in part on a condition. The condition may include, but is not limited to, a packet size, or a packet priority, or a combination thereof. According to the determination, the device may refrain from transmitting the reservation signal or allocate resources for the reservation signal from a same resource pool associated with the transmission of the packet or a dedicated resource pool according to a pre-reservation resource pattern.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive a configuration of a set of feedback channel occasions corresponding to a first sidelink data channel in a first listen-before-talk (LBT) sub-band, the set of feedback channel occasions located over multiple LBT sub-bands of an unlicensed radio frequency spectrum band. The UE may receive a data transmission over the first sidelink data channel and may determine to transmit feedback associated with the data transmission. The UE, based on the configuration of the set of feedback channel occasions, may perform LBT for each of the set of feedback channel occasions to determine which of the set of feedback channel occasions are available to the UE for transmitting the feedback associated with the data transmission. The UE may transmit feedback over one or more of the set of feedback channel occasions accordingly.

Abstract: Certain aspects of the present disclosure provide techniques for power allocation for sidelink feedback transmission. A method that may be performed by a user equipment (UE) include receiving one or more data transmissions from one or more other UEs, generating a feedback signal for each of one or more data transmissions, determining a transmission power of the feedback signal for each of one or more data transmissions based on at least one configuration associated with the feedback signal, and transmitting the feedback signal to each of the one or more other UEs using the determined transmission power.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive an indication of one or more parameters for communications over a sidelink channel during a first time period, where the one or more parameters may include a time threshold for a second resource pool. The wireless device may transmit data over a first resource pool of the sidelink channel during a first portion of the first time period based on the one or more parameters, the first resource pool including resources for communications between the first wireless device and a second wireless device. The wireless device may monitor the second resource pool during a second portion of the first time period for the time threshold, the second resource pool including resources for communications between the first wireless device and a third wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may support superimposed NR and LTE transmissions using an antenna port, in conjunction with an LTE-aware, NR slot structure (e.g., an NR V2X slot structure). In some aspects, the slot structure may protect portions of the LTE signal from interference, increasing LTE decoder robustness to interference which may provide opportunities for increasing the NR signal power. The UE may transmit a superimposed transmission of an LTE signal and an NR signal from a same antenna port in a same radio frequency resource. In some aspects, the slot structure may be modified so that the UE does not transmit when LTE reference signals are transmitted, so as to avoid interference with the LTE reference signals. A receiving UE may use the LTE reference signals to demodulate the LTE signal and the NR signal from the common time and frequency resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) in a wireless communications system, such as a vehicle-to-everything (V2X) communications systems, may communicate over sidelink to other UEs. The first UE may receive, from a base station, control signaling indicating a sidelink resource pool allocated for sidelink communication between the first UE and a second UE. The first UE may transmit an indication that superposition coding may be used to generate a concurrent sidelink and uplink transmission. The first UE may then transmit the concurrent sidelink and uplink transmission within a resource of the sidelink resource pool based on the indication. The second UE may decode the sidelink portion of the transmission, and the base station may decode the uplink portion of the transmission.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may support both access links and sidelinks (e.g., D2D communication links) for communications between one or more communication devices. Wireless devices may communicate sidelink control information in two stages, where first stage sidelink control information (SCI-1) may be transmitted via a physical sidelink channel and second stage sidelink control information (SCI-2) may be transmitted via a physical shared channel. In cases where sidelink communications use several (e.g., three or more) layers, the described layer mapping techniques may provide for robust transmission of control information, higher data rates, improved spectral efficiency, etc. For example, SCI-1 and/or SCI-2 may be mapped to physical channel layers by repeating the same modulation symbols across all layers, across groupings or sets of layers, across layers associated with each codeword, etc.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a first and second directional beam for communicating with one or more UEs on a first and second sidelink communication link. In some cases, the UE may identify a first sidelink feedback configuration for the first directional beam. The UE may also identify a second sidelink feedback configuration for the second directional beam, where the second sidelink configuration may be different from the first sidelink feedback configuration. In some examples, the UE may transmit an indication of the first sidelink feedback configuration and the second sidelink feedback configuration to the one or more UEs, where received feedback for sidelink messages sent over the directional beams may be based on the different sidelink feedback configurations. In addition, feedback resources may be based on a beam identifier of a beam used to transmit an initial sidelink message.
