Assuming that there are several supporting user terminals around the beneficiary user terminal willing to participate in the cooperation, the beneficiary user terminal determines the supporting user terminal to participate in communication cooperation according to the link status between the supporting user terminal and the base station. When the supporting user terminal is connected to the served base station When the user terminal is far away, the service quality of the service data of the beneficiary user terminal cannot be improved when the user terminal communicates and cooperates with the beneficiary user terminal

Embodiments of the present invention disclose a terminal coordination communications method, comprising: a benefit-receiving user terminal broadcasting a coordination request of transmitting target data in a coordinated manner, and receiving a signal quality parameter of the target data returned by each supporting user terminal receiving the coordination request; the benefit-receiving user terminal separately calculating a service quality increment of the target data according to the signal quality parameter corresponding to each supporting user terminal; and the benefit-receiving user terminal sending a control instruction of participating in coordination or quitting coordination to a corresponding supporting user terminal according to the service quality increment, so that the supporting user terminal executes a corresponding operation according to an indication of the control instruction. The present invention further discloses a user terminal. By means of the present invention, service quality of service data of a terminal can be effectively improved.
Description
technical field [0001] The present invention relates to the communication field, and in particular to a terminal cooperative communication method and a user terminal. Background technique [0002] Through antenna sharing and cooperative communication between terminals, the number of (virtual) antennas can be increased, breaking the above limitations, and improving system performance. On the one hand, through the cooperation between terminals, the space dimension that can be used by the terminal side can be effectively improved, and the system capacity can be improved. On the other hand, through cooperation between terminals, interference from neighboring terminals can be effectively suppressed and transmission quality can be improved. Different from the cooperative transmission on the network side, there is no high-speed optical fiber or other dedicated transmission links between terminal nodes to complete the exchange of shared information. Generally, information sharing ...
