Abstract

An uplink transmission method and a communication device are provided, can reduce the time delay of uplink cooperative transmission and improve the communication efficiency, and can be applied to theInternet of Vehicles, such as V2X, LTEV, V2V and the like, or can be applied to the fields of D2D, intelligent driving, intelligent networked vehicles and the like. The method comprises the followingsteps that: a cooperation terminal receives indication information from network equipment, wherein the indication information is used for indicating at least one time interval between a sidewalk resource and an uplink resource in cooperative transmission, the sidewalk resource is used for receiving data from a source terminal, the uplink resource is used for sending the data to the network equipment, and then, when the cooperation terminal receives first data from the source terminal on the first sidewalk resource, the cooperation terminal determines a first uplink resource from the uplink resource pool according to the first sidewalk resource and the indication information, and sends the first data to the network equipment on the first uplink resource.

Description

technical field [0001] The present application relates to the communication field, and in particular to an uplink transmission method and a communication device. Background technique [0002] Wireless communication technology has experienced rapid development in the past few decades. It has experienced the first generation of wireless communication systems based on analog communication systems, and the 2G wireless communication systems represented by the global system for mobile communication (GSM). , 3G wireless communication systems represented by wideband code division multiple access (WCDMA), and 4G wireless communication systems such as long term evolution (LTE), which have been widely used in the world and have achieved great success. system. The business supported by the wireless communication system has also developed from the initial voice and short message to now supporting wireless high-speed data communication. At the same time, the number of wireless connectio...
