Problems solved by technology

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.

Embodiment 1

[0056] Step 101: Cellular users and end-to-end users register with the central controller (eNB) of the cell to obtain the cell ID and power control information of the cell.

[0057] Step 102: Central controllers of adjacent cells exchange information of end-to-end users in their respective cells to determine the cell to which the end-to-end users belong.

[0058] Step 103: Each cellular user monitors the public control channel information broadcast by the central controller, and judges whether it is a cellular user causing communication interference; if yes, execute step 104; otherwise, end the whole process.

[0059] Each central controller broadcasts the information (including time and frequency) of the common control channel (CCCH), so that each cellular user can monitor the information of the common control channel (CCCH). If the signal power of the common control channel (CCCH) information monitored by the cellular user is greater than the set threshold value, and the fre...

Embodiment 2

[0081] In the above-mentioned embodiment 1, the cellular user causing communication interference is equipped with a GPS device. If the cellular user that produces communication interference is not equipped with a GPS device, the present invention can also be realized through the following steps:

[0082] Step 201: Cellular users and end-to-end users register with the central controller (eNB) of the cell to obtain the cell ID and power control information of the cell.

[0083] Step 202: Central controllers of adjacent cells exchange information of end-to-end users in their respective cells to determine the cell to which the end-to-end users belong.

[0084] Step 203: Each cellular user monitors the public control channel information broadcast by the central controller, and judges whether it is a cellular user causing communication interference; if yes, execute step 204; otherwise, end the whole process.

[0085] Step 204: The cellular user causing communication interference de...

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 ...
