Abstract

The invention discloses a disturbance control method based on distributed wireless network architecture. The method comprises the following steps of: receiving a broadcasting signal transmitted by a second receiving terminal through a first transmitting terminal, acquiring disturbance power which can be tolerated by the second receiving terminal, and calculating an upper limit value of the transmitting power, wherein the signals are transmitted in the upper limit value of the transmitting power so that the second receiving terminal is not disturbed. Meanwhile, the first transmitting terminal acquires a lower limit value of the required transmitting power of the first receiving terminal, in which the receiving signals are prevented from being disturbed. In addition, the invention also provides corresponding equipment and a system. By the method, equipment and system provided by the invention, the disturbance of a communication link to the receiving signals of other communication links is in an acceptable range, and the disturbance of the other communication links is avoided.

Description

technical field

[0001] The present invention relates to wireless communication technology, in particular to an interference control method, terminal and system based on a distributed wireless network architecture. Background technique

[0002] In the communication based on the cellular network, the communication between two terminals needs to be forwarded by the base station, and the same data packet occupies the air interface resources twice from the terminal to the base station, and then from the base station to the terminal. If the communication parties are relatively close and within the communication range of each other, the data packets are directly transmitted between the terminals without being forwarded by the base station, which can save half of the resources.

[0003] Direct communication between terminals (D2D, Device to Device) can enable direct communication between terminal devices without any intermediate infrastructure. Therefore, the direct communication o...
