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: 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: 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: Wireless communications systems and methods related to determining and transmitting delay measurements, such as propagation delay, between a base station (BS) and a user equipment (UE) are provided. In some aspects, a UE may receive, from a BS, a positioning reference signal (PRS). The UE may further transmit, in response to and at a predetermined time after the receiving the PRS, a sounding reference signal (SRS) to the BS. Further, the UE may receive, from the BS, a delay measurement corresponding to the PRS.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, SPS via RRC signaling. The apparatus may also determine a UE Rx-Tx time difference, the UE Rx-Tx time difference being equal to a difference between a downlink subframe reception time and an uplink subframe transmission time. The apparatus may also transmit, to the base station, the UE Rx-Tx time difference or receive, from the base station, a base station Rx-Tx time difference, the base station Rx-Tx time difference being equal to a difference between an uplink subframe reception time and a downlink subframe transmission time.

Abstract: A method for wireless communication performed by a wireless device includes aggregating a number of component carriers (CCs) to generate a virtual CC. The method also includes allocating data channel resources in the virtual CC based on a virtual bandwidth part (BWP) and allocating control channel resources in the virtual CC based on the virtual BWP. The method further includes communicating on a data channel based on the allocated data channel resources and communicating on a control channel based on the allocated control channel resources.
