Abstract: Methods, systems, and devices for wireless communications are described. In an example, a method includes a first node receiving a precision time protocol (PTP) message, identifying one or more timing domains to be supported by the first node based at least in part on the PTP message, and sending, to a second node of the wireless communication network, an indicator of the one or more timing domains to be supported by the first node. Another example at a node includes receiving, from additional nodes of the wireless communication network, indicators of one or more timing domains supported by the additional nodes, receiving a PTP message associated with a timing domain, and sending the PTP message to a subset of the additional nodes based at least in a part on the indicators of one or more timing domains supported by the additional nodes.

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: Aspects presented herein may enable a network entity to calculate a relative clock drift between a Tx antenna panel and an Rx antenna panel that use different RF hardware/circuits (e.g., clocks). In one aspect, a network entity obtains a plurality of RTT measurements between a Tx antenna panel, a device with a known position, and an Rx antenna panel over a period of time, where the Tx antenna panel is associated with a first clock and the Rx antenna panel is associated with a second clock. The network entity obtains a first timing delay associated with the device based on the plurality of RTT measurements. The network entity calculates a clock offset between the Tx antenna panel and the Rx antenna panel based on the obtained first timing delay associated with the device.

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 communication at a user equipment (UE) are described. A UE may receive control signaling configuring at least a first UE operation mode and a second UE operation mode. The UE may transmit one or more uplink messages to a base station in the unlicensed radio frequency spectrum band using a first set of parameters according to the first UE operation mode. In some examples, the UE may receive a control message comprising an indication that the UE is to switch from communicating according to the first configured UE operation mode to communicating according to the second configured UE operation mode. The UE may then transmit, in response to the received indication, one or more uplink messages to the base station in the unlicensed radio frequency spectrum band using a second set of parameters according to the second UE operation mode.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate configured grant uplink control information (CG-UCI) based at least in part on a determination that a configured grant (CG) retransmission timer is not configured. The UE may transmit the CG-UCI on a physical uplink channel to a base station. In some aspects, the UE may receive a configuration indicating that retransmission on a CG resource is enabled, in association with a determination that a CG retransmission timer is not configured. The UE may transmit a retransmission on the CG resource based at least in part on receiving a message that includes hybrid automatic repeat request feedback for one or more CG communications. Numerous other aspects are provided.
