Abstract: Certain aspects of the present disclosure provide techniques for indicating and determining whether one or more of multiple uplink transmissions scheduled by a common downlink control information (DCI) are based on a channel occupancy time (COT) initiated by the UE, a COT initiated by the network entity, or a combination of COTs initiated by the UE and network entity. The determination may be based on a direct indication in the DCI for one or more of the multiple uplink transmissions. The determination may also be based on determining the type of COT for the remaining uplink transmissions not directly indicated by the DCI. For example, the DCI may indicate a COT type for only a first one of the multiple uplink transmissions and the UE determines a COT type for the remaining uplink transmissions based on various conditions and criteria.

Abstract: In a method of wireless communication, a user equipment (UE) receives, from a base station (BS) in a first fixed frame period (FFP), downlink communication information (DCI), where the DCI indicates a scheduled uplink (UL) communication in a second FFP subsequent to the first FFP. The UE monitors for a downlink (DL) signal in the second FFP, and transmits, to the BS based on the monitoring and a first parameter indicating whether the scheduled UL communication is associated with a BS channel occupancy time (COT) or a UE COT, the scheduled UL communication.

Abstract: Aspects relate to selection of a channel access priority class (CAPC) table for a sidelink channel access procedure on an unlicensed carrier in a sidelink network. A wireless communication device (e.g., a UE or sidelink device) may select between a downlink CAPC table and an uplink CAPC table based on at least one of a sidelink mode, a role of the wireless communication device in the sidelink network, a cast type of sidelink traffic to be transmitted by the wireless communication device, or a channel type of the sidelink traffic.

Abstract: Aspects described herein relate to receiving a first downlink control information (DCI) indicating a first transmission configuration indicator (TCI) state to be applied for a first component carrier (CC) at a first beam applying time (BAT), receiving a second DCI indicating a second TCI state to be applied for the first CC or a second CC at a second BAT, and where the first BAT and the second BAT are within a same time period, applying the first TCI state or the second TCI state for one or more of the first CC or the second CC within the time period based at least in part on a first property of the first DCI and a second property of the second DCI. Other aspects relate to transmitting the DCI. Other aspects relate to when the BATs are not within the same time period.

Abstract: A configuration for resource allocation for PDCCH with multi-relay based communication. The apparatus determines a transmission time of a signal comprising a sequence of a plurality of PDCCHs to a target node. At least one relay is between the base station and the target node. The apparatus transmits, to each of the at least one relay, a relay configuration comprising scheduling information for each of the at least one relay to relay the signal. The scheduling information is based on a determination of the transmission time of the signal to the target node.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for improving communications between a user equipment (UE) and a base station in a shared radio frequency spectrum while the UE is operating in a discontinuous reception (DRX) mode. In particular, the UE may be configured to adapt operation in a DRX mode based on whether a base station has access to a shared radio frequency spectrum. For example, the UE may adjust a length of an on-duration for monitoring for a data transmission from the base station, adjust a periodicity for monitoring for control information from the base station, determine whether to keep monitoring for wake-up signaling from the base station, etc. based on whether the base station has access to the shared radio frequency spectrum. Further techniques for improving operation in a DRX mode are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate with multiple transmit receive points (TRPs) in a frame based equipment mode. A wireless node (e.g., the UE and/or one or more of the multiple TRPs) may determine, among the UE and the multiple TRPs, an initiating node that acquired a current channel occupancy time. The wireless node may determine a transmission pattern that includes one or more idle periods based at least in part on a fixed frame period structure associated with the initiating node that acquired the current channel occupancy time. The wireless node may refrain from transmitting during the one or more idle periods, wherein the one or more idle periods include at least an idle period associated with the wireless node. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may determine an energy pattern corresponding to a characteristic of the first wireless device. The energy pattern may include at least two sub-periods of different energy levels. The first wireless device may transmit the energy pattern on a channel (e.g., an unlicensed channel) prior to transmitting a first message on the channel to indicate the upcoming message to other devices. A second wireless device may monitor the channel during energy detection intervals and may detect the energy pattern. The second wireless device may determine the characteristic of the first wireless device based on detecting the energy pattern and may modify timing for transmission of a second message on the channel based on determining the characteristic. The first wireless device may transmit the first message on the channel based on transmitting the energy pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, an indication of at least one sidelink unified transmission configuration indicator (TCI) state, wherein the at least one sidelink unified TCI state includes at least one of: a joint forward link and reverse link TCI state, a separate forward link TCI state, or a separate reverse link TCI state. The first UE may communicate with the second UE on at least one of the forward link or the reverse link based at least in part on the indication of the sidelink unified TCI state. Numerous other aspects are described.
