Abstract: A method for wireless communication at a first user equipment (UE) includes performing, in a shared radio frequency band, a listen-before-talk (LBT) procedure for a channel occupancy time (COT). The method also includes selecting a first or second starting symbol for an initial slot based on a timing associated with the LBT procedure indicating a clearance, the initial slot having a first or second total number of symbols in accordance with selecting the first starting symbol or the second starting symbol. The method further includes selecting either a first or second demodulation reference signal (DM-RS) pattern from a group of DM-RS patterns in accordance with the initial slot having the first total number of symbols or the initial slot having the second total number of symbols. The method also includes transmitting, during the COT, sidelink information to a second UE via a sequence of slots that include the initial slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates, within each symbol of a plurality of symbols, an extra guard interval (GI) before data and a tail GI after the data. The UE may decode first data within a first symbol of the plurality of symbols at a first time location that is based at least in part on the extra GI and the tail GI within the first symbol. The UE may decode second data within a second symbol of the plurality of symbols at a second time location that is based at least in part on the tail GI within the second symbol.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may identify, in a radio frequency spectrum band a first resource for a sidelink synchronization signal block (S-SSB) and may perform a channel access procedure for the radio frequency spectrum band for the first resource. In a first example, a second resource for a sidelink message may overlap in time with the first resource and the UE may perform the channel access procedure based on the S-SSB being prioritized over the sidelink message. In a second example, the UE may perform the channel access procedure in accordance with a first value of a parameter for the channel access procedure associated with a first synchronization priority based on the UE being associated with the first synchronization priority. The UE may transmit an S-SSB over the first resource based on the channel access procedure indicating availability.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) transmitting feedback according to a codebook size, where the codebook size is determined according to a quantity of physical downlink control channel (PDCCH) monitoring occasions (PMOs) that occur before a feedback slot for transmitting the codebook. The UE may generate feedback according to a codebook that includes an entry corresponding to each PMO, which may indicate the feedback associated with the corresponding PMO. For example, if the UE receives a downlink control information (DCI) message during a PMO, the UE may set a corresponding feedback bit according to a decoding result of a transmission scheduled by the DCI.

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: A method of wireless communication by an initiating device, includes acquiring a channel occupancy time (COT) including multiple subsets of COT sharing resources. Each of the subsets includes fewer resources than the entire COT. The method also includes configuring a first responding device with a first of the subsets of COT sharing resources. The method further includes configuring a second responding device with a second of the subsets of COT sharing resources. A method of wireless communication by a responding device receives, from an initiating device, a first subset of multiple subsets of channel occupancy time (COT) sharing resources. The first subset differs from a second subset of COT sharing resources configured for another device. The method also includes selecting transmission resources from the first subset of COT sharing resources in response to detecting the initiating device acquired the COT, and then transmitting data on the selected transmission resources.

Abstract: Mechanisms for cross-carrier scheduling from a first cell to a second cell in a wireless networking scheme are provided. In one aspect, a method includes receiving, from a base station (BS), a first configuration for scheduling in a first cell having a first subcarrier spacing (SCS), wherein the first configuration is associated with a first search space in the first cell. The method further includes receiving, from the BS, a second configuration for scheduling in the first cell, wherein the second configuration is associated with a second search space in a second cell, and wherein the second cell is associated with a different second SCS. The method further includes determining a number of blind detections (BDs) based on at least one of the first SCS or the second SCS, and monitoring, based on the number of BDs, for downlink control information (DCI) in the first and second search spaces.
