Data transmission method and device

The invention relates to a data transmission method and device. The method comprises the steps of obtaining a target sample space, wherein the target sample space comprises sample data of a plurality of position points of a history path of a vehicle, and the sample data of each position point comprises a vehicle azimuth angle of the position point; determining discrete degree of the target sample space according to the vehicle azimuth angles, wherein the discrete degree is used for indicating bending degree of the history path; determining representative position points from the plurality of position points, wherein the representative position points are used for representing the history path of the vehicle; and sending the sample data of the representative position points to a target terminal. In this mode, the motion track of the vehicle can be positioned relatively precisely, the message transmission load can be reduced to the greatest extent, the packet loss problem resulting from message collision can be avoided, the realization of an upper layer application set can be supported well, and the secure driving between vehicles can be ensured to the greatest extent.

PDCCH method in enhanced CA and apparatus thereof

The invention provides a scheduling method and an apparatus in enhanced carrier wave aggregation. In a first step, UE receives a high level signaling and a first DCI, wherein the high level signaling indicates cell indexes of K service cells and the first DCI includes a first domain. In a second step, according to scheduling of the first DCI, a first wireless signal is processed on a first carrier wave indicated in the first domain. The first carrier wave is indicated by the first domain and a scheduling direction of the first DCI. The scheduling direction is an uplink and the processing is sending, or the scheduling direction is a downlink and the processing is receiving. The first carrier wave is the carrier wave of one service cell of the K service cells and the K is a positive integer. In the invention, a ''coupling'' relation of uplink and downlink scheduling is removed and scheduling flexibility is increased. In addition, a load size of a control signaling is not increased.
