Abstract

An embodiment of the present invention proposes a data transmission method, including: a second user equipment UE receiving a first message sent by a first UE or a base station, wherein the first message includes relay request information; the second UE Sending a second message to the base station according to the first message, where the second message includes information about a relay UE that the second UE requests as a relay UE for data transmission between the first UE and the base station; The second UE receives a third message sent by the base station, where the third message indicates that the second UE is the relay UE. In this way, in the embodiment of the present invention, the base station designates the second UE as the relay UE, so that the second UE can assist in data transmission between the base station and the first UE, ensuring the efficiency of data transmission.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, relate to a data transmission method, user equipment, and a base station. Background technique [0002] The base station and the user equipment (User Equipment, UE) located in the cell where it is located can perform data communication through a cellular link, such as figure 1 As shown, the UE 30 is located in the cell 40 of the base station 10, then the base station 10 and the UE 30 perform uplink and downlink data transmission through a cellular link. [0003] However, since the UE 20 is located in the cell 60 where the base station 50 is located, direct data communication cannot be performed between the base station 10 and the UE 20 . The data transmission between the base station 10 and the UE 20 needs to be performed by means of the base station 50 . For example, if the UE 20 needs to send uplink data to the base station 10, then the UE 20 first needs ...
