Multi-cell interference suppression method between cell and end-to-end hybrid network

Abstract

The invention discloses a multi-cell interference suppression method between a cell and an end-to-end hybrid network in the technical field of mobile communication. Communication interference is produced by a cell user, the ID (Identity) of an interfered end-to-end user is decoded by the cell user through monitored public control channel information monitored, and the information is reported to a central controller; information exchange is carried between the central controller and a central controller of an adjacent cell, and the exchanged information is transmitted by the central controller of the adjacent cell to the interfered end-to-end user in the local cell; frequency information capable of being multiplexed is obtained when uplink resource distribution information detected by the cell user of the local cell is received by the interfered end-to-end user, and the multiplexing frequency is adopted for end-to-end communication; and the communication priority of the cell user producing the communication interference is higher, and the interfered end-to-end user controls the transmission power to resist against interference caused by the cell user producing the communication interference. The quality of the communication of end-to-end users can be improved.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, in particular to a multi-cell interference suppression method of a cellular and end-to-end hybrid network. Background technique [0002] At present, there are two main structures of the wireless communication network: the centralized control cellular network and the distributed control Ad-hoc network. [0003] A cellular network means that communication between terminal equipment (User Equipment, UE) must be controlled by a base station (BS, or NB, eNB). [0004] The Ad-hoc network means that UEs can directly communicate with each other, or relay through another UE. [0005] In a cellular network, even if two terminal devices are very close to each other, a central controller such as a base station must be used to control communication, including control of transmission power and allocation of used resources. The advantage brought by such a centralized control system is that it is ...

However, due to the lack of flexibility of this method, it also limits its usage scenarios

[0016] It can be seen from the above three methods that no matter which method is used, resource coordination between D2D communication pairs across cells cannot be well realized and interference from other cells can be avoided.
