To provide a method for managing transmission of MBS.SOLUTION: The method is implemented in a CU of a distributed base station including the CU and a DU. The method includes receiving, from a core network (CN), a request to configure resources for transmitting downlink (DL) MBS data associated with an MBS session, determining, based on at least one of (I) capabilities of the DU or (ii) capabilities of UEs that have joined the MBS session, whether the DU is to transmit the MBS data to the UEs on at least one of the air interfaces using a PTP delivery mechanism or a PTM delivery mechanism, and causing the DU to transmit the MBS data according to the determined delivery mechanism.SELECTED DRAWING: Figure 5A

The invention discloses a master-slave vehicle cooperative control method and device. A master vehicle and a slave vehicle establish a point-to-multipoint communication link through a short-distance communication unit. The mother vehicle broadcasts a self motion state containing historical data and a control instruction to the son vehicle through the link; the child vehicle establishes a mother vehicle motion prediction model based on historical data, and monitors a link state in real time through periodic heartbeat communication. And when the child vehicle judges that the link has a fault according to the communication quality parameter, immediately starting the prediction model, calculating the predicted motion state of the mother vehicle according to the finally received effective motion data, continuously executing following control according to the predicted motion state, and attempting to recover the communication at the same time. Under the condition of unstable communication, the child vehicle can autonomously predict and follow the mother vehicle, frequent emergency stop is effectively avoided, and the operation continuity and the system robustness of the vehicle formation in a complex environment are remarkably improved.

Disclosed herein are systems and methods relating to wireless communication mesh networks. In one aspect, the disclosed systems and methods may involve (1) a preexisting fiber network associated with a geographical area that includes buildings, where the preexisting fiber network comprises preexisting fiber links, (2) a first fiber link that is spliced into a given one of the preexisting fiber links coupled to the preexisting fiber network at a given location that was identified as being convenient for extending the preexisting fiber network, (3) a second fiber link that is deployed between the given location and a given building that is closest to the given location, where the given building is configured to serve as a seed node of a wireless communication mesh network that has backhaul connectivity through the preexisting fiber network, and (4) one or more point-to-point or point-to-multipoint communication links that originate from the seed node.

Systems and methods for point to multipoint communications are provided. In one example, a system includes one or more modal antennas. Each modal antenna is configured to operate in a plurality of modes. The system can include a transceiver configured to communicate with a plurality of client devices over a wireless communication medium via the one or more modal antennas over a plurality of frames. The system can include one or more control devices configured to control the operation of the one or more modal antennas. For each of the plurality of frames communicated to one of the plurality of client devices, the one or more control devices are configured to determine a selected mode of the plurality of modes to communicate during the frame and to operate at least one of the one or more modal antennas in the selected mode during the frame.
