Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions to at least one receiver UE across transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting at least one LBT report to the network entity on a physical uplink control channel (PUCCH) resource that occurs before another PUCCH resource used for transmitting acknowledgment feedback for the PSSCH transmissions.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sidelink channel access via a floating channel occupancy. In some aspects, a cellular device may operate within a proximity of one or more wireless fidelity (Wi-Fi) devices and may conditionally support a search space associated with a floating sidelink synchronization signal block (SSB). For example, if the cellular device detects that the Wi-Fi devices are precluding the cellular device from acquiring channel access or otherwise making it relatively more difficult for the cellular device to acquire channel access, the cellular device may enable or active a use of the search space associated with the floating sidelink SSB. If enabled or activated, the cellular device may transmit a floating sidelink SSB within the search space independent of slot boundaries upon a successful listen-before-talk (LBT) procedure.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support a slot transmission detection procedure for sidelink communications. A sidelink user equipment may monitor, during a slot and within one or more subbands, for signaling associated with a first sidelink transmission that corresponds to resources that span a duration of the slot. The signaling may include sidelink control information, a demodulation reference signal, or other sidelink signaling associated with the first sidelink transmission. The user equipment may determine a signal strength or one or more other parameters associated with the signaling. The user equipment may determine whether to transmit a second sidelink transmission having a duration that is less than a first duration of the first sidelink transmission based on the signal strength, the one or more parameters, or both associated with the signaling.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include performing a clear channel assessment (CCA), transmitting, to a first UE based on the CCA being successful, a first transport block (TB) via a first sub-PSSCH associated with a first sub-slot, and transmitting, to at least one of the first UE or a second UE, a second TB via a PSSCH associated with a slot.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive sidelink control information from a second wireless device. The sidelink control information may include an allocation of a first set of resources for a sidelink transmission from the second wireless device to the first wireless device, along with an indication that schedules a second set of resources for additional sidelink transmissions between the first wireless device and the second wireless device that are scheduled to occur after the sidelink transmission from the second wireless device to the first wireless device. Based on the received indication, the first wireless device may communicate with the second wireless device via a sidelink shared channel using the first set of resources and the second set of resources.

Abstract: Methods, systems, and devices for wireless communications are described that provide for user equipment (UE) in sidelink communications to agree on transmission directions and a traffic pattern for a sidelink channel, where a transmitting UE has higher priority in channel access than a receiving UE. When establishing a connection via sidelink, two or more UEs may agree on a resource pattern for a set of sidelink resources where a first UE has higher priority than a second UE for a first subset of resources. The first UE may be given higher priority in the first subset of resources through adjustments to a channel access procedure for requesting channel access, adjustments to one or more access thresholds or channel access priority classes, contention window adjustments, or any combinations thereof. Layer one signaling may be used to reconfigure channel access priority and the traffic pattern between UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating an aggregated sidelink resource reservation rule for reserving time-contiguous transmission time intervals. The UE may transmit a sidelink control reservation message based on the aggregated sidelink resource reservation rule. The sidelink control reservation message may indicate a starting transmission time interval for reserving a set of time-contiguous transmission time intervals in a sidelink shared channel. Additionally or alternatively, the sidelink control reservation message may indicate a quantity of the set of time-contiguous transmission time intervals reserved for transmission of a set of aggregated sidelink messages. The UE may transmit the set of aggregated sidelink messages via the set of time-contiguous transmission time intervals of the sidelink shared channel indicated in the sidelink control reservation message.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may perform a channel access procedure to gain access to a bandwidth part in a shared spectrum for sidelink communications with a second UE. The first UE may transmit a signal to the second UE using one or more sub-bands of the bandwidth part, and the signal may include one or more sidelink synchronization signal blocks (S-SSBs) multiplexed with frequency resources associated with a physical sidelink shared channel (PSSCH). The one or more S-SSBs may be transmitted using a set of symbol periods of a transmission time interval (TTI) (e.g., a slot) that are preceded by a least four initial symbol periods of the TTI. In some examples, the first UE may transmit a sidelink control information (SCI) message indicating which of the one or more sub-bands include the one or more S-SSBs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit signaling that includes an indication of a resource block set configuration to one or more sidelink UE, the resource block set configuration based at least in part on a type of sidelink communications to be performed and from a set of available resource block set configurations that comprises at least a minimum overlapping frequency resource block set configuration. The UE may perform the sidelink communications with the one or more sidelink UE according to the resource block set configuration.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a second UE, a configuration for receipt of a sidelink resource pool message, determining that the first UE has information to be transmitted to the second UE via sidelink communications, receiving, in accordance with the configuration, the sidelink resource pool message, identifying, based on the sidelink resource pool message, a resource pool that includes sub-channels for sidelink communications to the second UE, and attempting to access a sub-channel of the resource pool in order to transmit the information to the second UE via sidelink communications.
