Embodiment Construction

[0038] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0039] like figure 1 As shown, this embodiment describes a method for increasing the uplink transmission rate between a user and a base station by using cooperative communication. Any two user terminals are used as the first user terminal MU1 and the second user terminal MU2, and the first user terminal MU1 and the second user terminal MU2 The two user terminals MU2 perform point-to-point cooperative communication with the base station according to the cooperative communication conditions.

[0040] When the second user terminal MU2 assists the first user terminal MU1 to communicate with the base station, the first user terminal MU1 sends the signal generated by itself to the second user terminal MU2 at the first uplink transmission rate R1,...

Abstract

The invention discloses a method for improving the uplink transmission rate between a user and a base station by using cooperative communication, and utilizes the mutual interference between two users to maximize the uplink transmission rate of the user. At the same time, with cooperative communication, after knowing the first uplink transmission rate R1 of one user, the second uplink transmission rate R2 that another user can achieve and how to allocate power for cooperative communication between the two users can be calculated accordingly. Wherein, the second uplink transmission rate R2 is determined in the feasible range of the transmission rates of the first user terminal MU1 and the second user terminal MU2 according to the first uplink transmission rate R1, and the determination method is: on the edge curve of the feasible range , set multiple demarcation points C, divide the feasible domain into multiple sub-areas, match the optimal second uplink transmission rate R2 in the corresponding sub-areas according to the value of the first uplink transmission rate R1, and determine the first user The transmission power of the terminal MU1 and the second user terminal MU2.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a cooperative communication method, a method for improving the uplink transmission rate between a user and a base station by using cooperative communication. Background technique [0002] Nowadays, full-duplex wireless communication systems are gaining more and more attention in the industrial and academic fields. Because it can not only significantly improve spectral efficiency, but also solve the problems of hidden nodes and end-to-end delay. [0003] However, when the full-duplex technology is applied to the cellular system, mutual interference between users becomes a major problem affecting communication. Generally, there are two ways to reduce the impact of mutual interference on communication transmission: the first method is dynamic elimination; the second method is to use this interference, such as using point-to-point communication and optimizing energy distributio...
