Embodiments of this application disclose a data transmission method, to reduce a delay. If a network device receives burst data, the network device preferentially sends the burst data. The burst data may be data whose data amount is greater than a data amount threshold.

A network device includes processing circuitry and a plurality of ports. The ports connect to a communication network. The processing circuitry is configured to receive, via an input port, data packets and probe packets that are addressed to a common output port, to store the data packets in a first queue and the probe packets in a second queue, both the first queue and the second queue are served by the output port, to produce telemetry data indicative of a state of the network device, based on a processing path that the data packets traverse within the network device, to schedule transmission of the data packets from the first queue at a first priority, and schedule transmission of the probe packets from the second queue at a second priority higher than the first priority, and to modify the scheduled probe packets so as to carry the telemetry data.

A method for aggregating and regulating messages in a network that has a plurality of pairs of nodes and two transmitting/receiving devices communicating via a bidirectional channel. The method is implemented by each of the transmitting/receiving devices. Each received message may be segmented into packets of a predefined size, and each packet may be allocated to a queue that depends on the origin, the destination, and the priority of the message. One or more frames may then be created, and packets of the queues may be inserted into the frames. Frames may then be sent via the bidirectional channel over a predefined time interval, the number of frames sent over the time interval being dependent on the maximum throughput of the channel and on the useful throughput in each of the transport directions of the channel.

The present invention provides a method and device for transmitting/receiving an uplink signal. When a user equipment of the present invention is configured by multiple cell groups and multiple pieces of uplink control information (UCI) to be transmitted by the user equipment in a subframe are generated, the user equipment separately transmits, to the multiple cell groups, the UCI one by one from the piece of UCI having the highest priority, and drops the pieces of UCI having lower priorities among the multiple pieces of UCI.

A method and device for wireless data transmission are described. A device receives sets of sensor data associated with respective sensor measurements for a vehicle. The device determines a priority for each of the sets of sensor data based on an amount of data stored for that sensor measurement in a number of data queues, and selectively stores each of the sets of sensor data in one of the data queues based on a threshold data throughput rate of a wireless network and the priority of each set of sensor data. The device transmits, to a second computing device via the wireless network, at least some of the sets of sensor data from the data queues based on a current data throughput rate of the wireless network and a priority level of each of the data queues.

User equipments (UEs) may be scheduled by determining relative priorities of data radio bearers (DRBs), each DRB associated with a respective UE. A limit is established dividing radio resources available for allocation in the cell during a scheduling period into at least a first limited portion and a second remaining portion. According to the determined relative priorities: a) up to the first limited portion of the radio resources are allocated to only the DRBs that have a guaranteed bit rate (GBR), and thereafter b) the second remaining portion of the radio resources are allocated to only the DRBs which have not been fully allocated from the first limited portion. Schedules indicating this allocation are transmitted to the respective UEs. In carrier aggregation where each carrier aggregated cells has a respective plurality of DRBs, relative priorities for each respective plurality of DRBs are determined for each carrier aggregated cell.
