Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive a message indicating a configuration or a sidelink discovery burst transmission window. The configuration may include time periods for transmitting multiple sidelink synchronization signals. The first UE may perform a channel access procedure during the sidelink discovery burst transmission window. The first UE may perform the channel access procedure for transmitting one or more of the sidelink synchronization signals according to a pattern indicated by the configuration. The pattern may be based on a quasi co-location relationship between associated pairs of the sidelink synchronization signals. The first UE may transmit the one or more sidelink synchronization signals to a second UE in accordance with the pattern indicated by the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive an encoded signal including a set of information blocks. Each information block may include a set of encoded information bits and a set of cyclic redundancy check (CRC) bits. The receiving device may perform a staircase decoding procedure to decode the set of encoded information bits of a selected information block that is part of a subset of the set of information blocks that is within a sliding window. The staircase decoding procedure may include one or more iterations of a decoding process applied to the subset of the set of information blocks. The receiving device may perform, inbetween iterations of the staircase decoding procedure applied to the subset of the set of information blocks within the sliding window, a CRC procedure based on the set of CRC bits in the set of information blocks.

Abstract: A method of wireless communication by a user equipment (UE) operating in frame-based equipment (FBE) mode includes transmitting, to a base station, during a shared base station first channel occupancy time (COT), a first physical uplink shared channel (PUSCH) actual repetition prior to an idle period in a first fixed frame period of the base station. The method also includes attempting to detect a downlink signal during a second COT in a second fixed frame period of the base station that occurs immediately after the idle period. The method further includes transmitting a second PUSCH actual repetition in the second fixed frame period after the idle period, in response to detecting the downlink signal and in response to a processing timeline being satisfied.

Abstract: Apparatus, methods, and computer-readable media for network coding for handover are disclosed herein. A base station (BS) transmits a first group of encoded packets to a first road side unit (RSU) over a first radio access network (RAN) interface. The BS initiates a handover procedure between the first RSU and a second RSU. The BS receives, from the first RSU, a release acknowledgment associated with the handover procedure and feedback associated with the first group of encoded packets. The BS transmits network coding level information to the second RSU over a second RAN interface based on the feedback. The network coding level information indicates a number of missing encoded packets within the first group of encoded packets for the second RSU to transmit to the UE. The BS transmits, to the UE, a second group of encoded packets associated with the number of missing encoded packets at the second RSU.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a channel occupancy time (COT) duration indication that indicates a first COT duration associated with a first channel occupancy initiated by the base station. The UE may initiate, during a time duration that is outside of the first COT duration and based at least in part on performing a listen-before-talk procedure, a second channel occupancy having a second COT duration. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to channel access in a shared radio frequency band in an unlicensed spectrum or a shared spectrum are provided. A wireless communication device determines a channel access procedure based on whether one or more channel access conditions are satisfied for accessing an unlicensed frequency band. The one or more channel access conditions are associated with at least one of sensing across multiple channel occupancy times (COTs), a transmission beam characteristic, a transmit power, a transmission duty cycle, or a beam dwell time. The wireless communication device transmits, based on the channel access procedure, a communication signal in the unlicensed frequency band.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, encoded packets that are encoded using network coding. The encoded packets may be associated with source packets that represent a data set. The UE may attempt to recover the source packets from the encoded packets received from the base station. Upon failing to recover the source packets, the UE may transmit, over a sidelink channel, a message requesting sidelink assistance in recovering the source packets.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may convey uplink control information (UCI) to a base station using a multi-slot or single slot uplink channels. In some cases, however, transmissions scheduled on a first set of resources allocated for multi-slot transmission of a first uplink channel may overlap with one or more slots of a second set of resources allocated for multi-slot transmission of a second uplink control channel. Accordingly, the UE may employ a number of different techniques to transmit the UCI. In a first case, the UE may map the UCI to at least one of the overlapping slots of the first uplink channel. In a second case, the UE may drop the second uplink channel which carries the UCI. In a third case, and the UE may map the UCI to an overlapping slot of the second uplink channel.
