Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a first control resource pool associated with sidelink control signaling during a first sensing window and monitor a portion of a second resource pool associated with sidelink data signaling during a second sensing window. The UE may perform joint resource selection on the first resource pool and the second resource pool based on the monitoring during the first and second sensing windows. The UE may transmit a sidelink control information message including resource indication fields to reserve the selected sidelink control channel resources and selected sidelink shared channel resources. The UE may transmit the sidelink data message on one or more of the reserved sidelink shared channel resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive an inter-UE coordination request message from a second UE, the inter-UE coordination request message identifying a request for resource scheduling information for the first UE, the second UE, or both. The first UE may transmit an inter-UE coordination response message comprising the scheduling information to the second UE, the scheduling information comprising an indication of one or more of a resource block set and interlacing pattern frequency configuration for multi-slot burst communications between the first UE and the second UE or a starting slot and slot burst length configuration for the multi-slot burst communications between the first UE and the second UE.

Abstract: Methods, systems, and devices supporting flexible frequency domain resource allocation (FDRA) for sidelink are described. For example, a wireless device may receive, over a sidelink channel, control information including a parameter associated with a first FDRA of a first transport block (TB) associated with an initial transmission and an indication of a second FDRA of a second TB associated with a subsequent transmission after the initial transmission. The wireless device may identify the first FDRA of the first TB based on receiving the control information and may communicate one or more signals over the sidelink channel based on identifying the first FDRA of the first TB and receiving the indication of the second FDRA of the second TB. In some examples, the wireless device may receive, over a second sidelink channel, second control information including a second parameter associated with a size of the second TB.

Abstract: Channel occupancy time (COT) aware sensing and resource selection for new radio-unlicensed (NR-U) sidelink operations is disclosed. A first sidelink user equipment (UE) determines a sensing window or resource selection window (RSW) based on a projected listen-before-talk (LBT) completion time. The UE may sense for a subset of sideline resources within the RSW and COT-SI from a neighboring sidelink UE including identification of a COT initiated by the neighboring UE and one or more parameters associated with the COT. The UE may identify in-COT resources of located within the COT and out-of-COT resources located outside of the COT and then randomly select a set of transmission resources from the in-COT and out-of-COT resources. The UE may then transmit to a second UE using the set of transmission resources.

Abstract: Some aspects described herein relate transmitting, to a receiving UE, a sidelink control information (SCI) that schedules multiple transport blocks (TBs) of shared channel communications in multiple time divisions, and transmitting, to the receiving UE and based on the SCI, the multiple TBs of shared channel communications in the multiple time divisions. Other aspects relate to receiving, from a transmitting UE, a SCI that schedules multiple TBs of shared channel communications in multiple time divisions, and receiving, from the transmitting UE and based on the SCI, the multiple TBs of shared channel communications in the multiple time divisions. Additional aspects relate to configuring the UEs in this regard.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a base station transmitting to a user equipment (UE) a partial bandwidth configuration for uplink transmissions, where the partial bandwidth configuration may indicate a channel interlace and a portion of a channel bandwidth, for example, for autonomous uplink (AUL) transmissions. The base station may also transmit to the UE an AUL configuration including a group identifier. The UE may determine a starting offset with respect to an AUL subframe for a partial bandwidth transmission based on the group identifier. In some cases, different UEs may be grouped into groups of UEs allocated non-overlapping resources, and UEs allocated overlapping resources may have different starting offsets to begin transmitting. According to the determined starting offset, the UE may perform the partial bandwidth transmission over the channel interlace and the portion of the channel bandwidth.

Abstract: Wireless communications systems and methods related to COT aware autonomous sidelink sensing are provided. A first user equipment (UE) selects at least a first resource from available resources in a sidelink resource pool within a shared radio frequency band. The selecting the first resource may be based on a channel-access gap preceding each resource of the available resources. The first UE further transmits, to a second UE using the selected first resource, one or more data blocks for a sidelink transmission.

Abstract: Wireless communications systems and methods related to LBT aware autonomous sidelink sensing are provided. A first UE determines, based on a projected listen-before-talk (LBT) completion time, at least one of a sensing window or a first resource selection window. The first UE senses, based on the determining, in a sidelink resource pool within a shared radio frequency band during the sensing window. The first UE identifies, based on the sensing, a subset of resources from the sidelink resource pool that are within the first resource selection window. The first UE selects at least a first resource from the subset of resources. The first UE transmits, to a second UE using the selected first resource, a sidelink transmission.
