Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a unicast connection over a sidelink communications with a second UE. To establish the unicast connection over the sidelink, the first UE may transmit a request message (e.g., a first message) to the second UE, and the second UE may transmit a response message (e.g., a second message) to the first UE accepting the request. The unicast connection over the sidelink may then be established between the first UE and the second UE, and user data may then be transmitted over the sidelink on the established unicast connection. Additionally, the first UE may transmit a connection complete message (e.g., a third message) to the second UE indicating that the unicast connection has been established. The request message, the response message, and the connection complete message may be radio resource control (RRC) messages.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether sufficient resources are available to perform a transmission in a current slot. The UE may transmit the transmission in the current slot, transmit an early reservation signal for a future resource, or determine whether sufficient resources are available to perform the transmission in a subsequent slot based at least in part on a probability-based determination and based at least in part on whether sufficient resources are available to perform the transmission in the current slot. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that may enable a user equipment (UE) to transmit sidelink data within an interference avoidance resource scheduling scheme. For example, a UE may determine to segment a data packet for transmission in a vehicle-to-everything (V2x) system (e.g., to ensure that each segment fits within one transmission time interval (TTI)). In some cases, a UE may identify a data packet for transmission, may determine that the size of the data packet exceeds a threshold size, may segment the data packet to ensure each segment fits within one TTI, and may transmit the data packet segments (e.g., to additional UEs), where said transmissions may be discontinuous. In some examples, a UE may determine to segment the data packet and then encode the data packet. Additionally or alternatively, the UE may determine to encode the data packet and then segment the data packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine hybrid automatic repeat request (HARQ) feedback for one or more sidelink communications received from one or more other UEs. The UE may identify one or more sets of subcarriers of a HARQ feedback occasion for the HARQ feedback for the one or more sidelink communications. The UE may transmit, to the one or more other UEs and on a sidelink, the HARQ feedback for the one or more sidelink communications using the one or more sets of subcarriers of the HARQ feedback occasion. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a packet at a transmitter of the UE for transmission in a sidelink network. The UE may select one or more resources for transmission of the packet based at least in part on a reservation status of the one or more resources, wherein at least one of the one or more resources is a reserved resource that is reserved by another UE. The UE may transmit the packet using the one or more resources based at least in part on selecting the one or more resources. Numerous other aspects are provided.

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: Aspects of the present disclosure propose a mechanism whereby a nearby device may detect scenarios where one device is unable to receive communications from a transmitting device. For example, the nearby device may detect that concurrent transmissions of a transmitting device and intended recipient prevent reception by the intended recipient and provide feedback to the transmitting device. Rather than blindly retransmitting, the transmitting device may only retransmit when it receives feedback from the nearby device, saving power and avoiding unnecessary transmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may generate a pseudorandom noise (PN) sequence, modulate the PN sequence based at least in part on a modulation order parameter, and transmit the PN sequence in one or more symbols prior to transmitting sidelink data. The one or more symbols used to transmit the PN sequence may be used for automatic gain control (AGC) training at a receiving device. The user equipment may then transmit the sidelink data in a plurality of symbols that are subsequent in time relative to the one or more symbols used to transmit the PN sequence, and the receiving device may process the sidelink data based on the AGC training. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a selection window after an arrival of a packet. The selection window may be selected based at least in part on a delay budget associated with the packet. The UE may determine, based at least in part on the selection window, a control exclusion zone value. The UE may perform, based at least in part on the control exclusion zone value, a resource selection associated with determining available resources for transmitting a set of transmissions associated with the packet. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a plurality of ratios of free resources in a historical time window using respective control exclusion parameters corresponding to the plurality of ratios of free resources. The UE may determine a particular control exclusion parameter based at least in part on a ratio of free resources, of the plurality of ratios of free resources, satisfying a threshold. The UE may select a resource for a future transmission based at least in part on the particular control exclusion parameter. The UE may reserve the selected resource. Numerous other aspects are provided.
