    摘要： A network node is connected to a plurality of antenna nodes that are located along a constrained path where a plurality of wireless communication devices are located. The antenna nodes are controlled to maintain reception radio lobes substantially along the path such that the wireless communication devices can perform uplink radio communication with the network node via the reception radio lobes. At least one radio frequency, RF, signal is detected and a determination is made that the detected at least one RF signal originates from a respective wireless communication device of a specific subset among said plurality of wireless communication devices. The specific subset comprises wireless communication devices that are associated with a common radio frequency offset. An allocation of a common uplink radio communication resource is then made for all wireless communication devices in the specific subset of wireless communication devices.

    摘要： According to some embodiments, a method performed by a wireless device capable of operating in a time sensitive network (TSN) comprises obtaining a time synchronization capability of the wireless device and transmitting an indication of the time synchronization capability to a network node. In particular embodiments, the time synchronization capability comprises one or more of a downlink receive tracking accuracy supported by the wireless device, a receive to transmit relative timing accuracy supported by the wireless device, an internal timing accuracy supported by the wireless device, and a propagation delay (PD) compensation method selection capability supported by the wireless device.

    摘要： A method and system are disclosed for a network node or wireless device (WD) to communicate with another WD or network node. The node or WD is configured to perform at least one timing measurement over a measurement period (T1) on signals transmitted between the node or WD and another node or WD and, during T1, determine if there is any change in a fixed time offset (FTO) used by the nodes for transmitting a reference signal. If there is a change in the FTO over T1, the network nodes or WDs are configured to perform an operational task and, if not, continue performing the timing measurement over T1. The operational tasks may include discarding the timing measurement, restarting the timing measurement, extending the measurement time, informing another node about a change in the FTO or informing another node about an action taken by the network node or WD.
