Problems solved by technology

[0005] However, in the existing repetition mechanism, because there is no need to consider the feedback, when the Tx UE adopts the repetition mechanism, it selects the carrier to implement the repetition mechanism completely according to its own wishes and capabilities, and does not need to care whether the Rx UE can receive on these carriers at the same time, so result in poor data transmission

Abstract

The invention relates to a multi-carrier data transmission method and device. The method comprises: first user equipment performing data transmission between equipment through a first carrier; determining a second carrier for executing multi-carrier data transmission according to the state of the second user equipment; and performing data transmission between the devices through the first carrierand the second carrier. The device comprises a second carrier determination module used for determining a second carrier for executing multi-carrier data transmission according to the state of seconduser equipment when data transmission with the second user equipment is carried out through a first carrier; and a transmission module used for carrying out transmission between the devices through the first carrier and the second carrier. According to the embodiment of the invention, the second carrier for executing the multi-carrier transmission is determined according to the state of the seconduser equipment, and by adopting the multi-carrier data transmission method and the multi-carrier data transmission device, the multi-carrier transmission effect can be improved, and the transmissionstability is ensured.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, and in particular to a multi-carrier data transmission method and device. Background technique [0002] In the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), Long Term Evolution (LTE, Long Term Evolution) introduces direct communication (Sidelink Communication). Direct communication can be performed between different user equipments (UE, User Equipment). [0003] Currently, 3GPP is studying the introduction of Vehicle-to-Everything (V2X, Vehicle-to-Everything) in the fifth generation mobile communication network (5G). Because the 5G system can provide greater bandwidth and lower latency, it can better meet the business needs of V2X. [0004] In order to improve the reliability of V2X data transmission, V2X transmission can adopt the duplication mechanism, that is, the sending UE (Tx UE) can transmit the same data to the same UE on two different carr...
