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: Wireless communications systems and methods related to routing communications in a multiple-relay environment are provided. A base station (BS) transmits, to one or more wireless communication devices, a reference signal configuration indicating one or more reference signal resources. The base station receives, from a first wireless communication device of the one or more wireless communication devices, a channel state report based on one or more reference signals in the one or more reference signal resources. The channel state report includes channel measurement information for one or more links, each link connecting a wireless communication device of the one or more wireless communication devices to a user equipment (UE). The BS transmits, to the UE via a second wireless communication device of the one or more wireless communication devices based on the channel state report, a data signal.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling comprising an indication of a format for a channel state information report indicating channel state information for a sidelink channel between the first UE and a second UE. The first UE may determine the channel state information for the sidelink channel between the first UE and the second UE. The first UE may configure a layer one uplink control message to indicate the channel state information report according to the format. The first UE may transmit, based at least in part on the format, the layer one uplink control message to a base station indicating the channel state information report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, using one or more beams included in a first beam group associated with the UE, a channel occupancy ratio (CR) for the first beam group. The UE may perform an action if the CR for the first beam group does not satisfy a CR limit associated with the first beam group. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a base station including a resource configuration indicating a resource block includes a synchronization signal block (SSB) and a control resource set (CORESET). The resource configuration may be based on a sub-carrier spacing (SCS) configuration. The UE may receive the SSB and the CORESET from the base station within the resource block and according to the resource configuration. The UE may receive one or more reference signals and may decode the SSB and the CORESET based on the resource configuration and the reference signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay device may receive, from a base station, a data message that includes at least first control information associated with a first user equipment (UE) and second control information associated with a second UE. The relay device may transmit, to the first UE, the first control information based at least in part on information included in a header associated with the data message. The relay device may transmit, to the second UE, the second control information based at least in part on the information included in the header. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a set of downlink control channel candidates that are associated with each other, the set of downlink control channel candidates including a first downlink control channel candidate in a first transmission time interval (TTI) and a last downlink control channel candidate in a second TTI subsequent to the first TTI. The UE may receive, based on the monitoring, at least one repetition of downlink control information (DCI) within one of the first downlink control channel candidate or the last downlink control channel candidate, the DCI scheduling a transmission between a base station and the UE. The UE may apply a scheduling offset associated with the transmission based on a timing of the last downlink control channel candidate, and may subsequently communicate with the base station via the transmission based on the scheduling offset.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, physical downlink control channel (PDCCH) candidates in first and second search space (SS) sets may be located in a same slot. When both SS sets have the same periodicity and the same offset, the UE may determine that SS sets are linked. The UE may expect the same number of monitoring occasions for each SS set within the slot, and may determine that a monitoring occasion in the first SS set having a first index value is linked with a monitoring occasion in the second SS set that has the same index value. The UE may determine that monitoring occasions for the different SS sets that have the same periodicity but different offsets are located in different slots, and that rules are satisfied such that a first PDCCH repetition is located in an earlier slot than the second PDDCH repetition.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, individual physical downlink control channel (PDCCH) candidates of a first search space (SS) set in a first transmission time interval (TTI) may be linked to corresponding PDCCH candidates of a second SS set in a second TTI. The UE may count combinations of the PDCCH candidates in the first TTI and the PDCCH candidates in the second TTI toward a blind decoding (BD) limit of only the second TTI, or the BD limit of the first TTI and the BD limit of the second TTI. The first SS set and second SS set may be in the same TTI. The UE may consider, with respect to a BD limit, a first set of PDCCH candidates, a second set of PDCCH candidates, and a combination of the first and second set of PDCCH candidates, together, or separately, or any combination thereof.

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, search space (SS) configuration information associated with switching between a first SS set group and a second SS set group. The UE may receive, from the base station, downlink control information associated with physical downlink control channel repetitions based at least in part on switching between the first SS set group and the second SS set group. Numerous other aspects are described.
