Problems solved by technology
However, inter-cell cooperative transmission is currently mainly reflected in the interference coordination of wireless transmission of service data, and the accurate analysis of the control channel is the prerequisite for effective analysis of the service channel and the necessary support for the realization of the CoMP idea; due to the current system configuration of the control channel , the problem of avoiding interference from adjacent cells has not been considered. Therefore, in the existing wireless communication system that introduces the coordinated multi-point transmission technology, there will still be physical resources where the above-mentioned inter-cell control channel or control information is located due to the unreasonable configuration of the control channel. interference issues, which can affect system performance

Embodiment Construction
[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] The core idea of the present invention is to divide the resource pool dedicated to users in the CoMP area from the control channel resource pool of the system in advance, then allocate the resources in the dedicated resource pool to each cell in the CoMP area, and ensure that The configured resources are different, so that the adjacent cell interference problem caused by the use of the same frequency resource by different edge users of adjacent cells can be avoided when sending control signaling.
[0021] figure 1 It is a schematic flow chart of Embodiment 1 of the present invention, such as figure 1 As shown, this embodiment mainly includes:
[0022] Step 101: According to the size of the coordinated multi-point CoMP area in a...

The invention discloses a control information transmitting method and a control information transmitting device, wherein the control information transmitting method comprises the following steps: a sub resource pool special for CoMP (Coordinated Multiple Point) area users is planned and reserved from the control channel resource pool of a system in advance according to the size of a CoMP area, according to the principle that different plots use different resources, all resources in the sub resource pool are assigned to plots covering the CoMP area; when control information needs to be transmitted to a user in the CoMP area in a control channel, control channel resource is prior selected from the resources in the sub resource pool allocated to the serving plot involving the user and is allocated to the user; and the control information is added to the selected control channel and is transmitted to the user. By adopting the control information transmitting method and the control information transmitting device, the neighboring interference generated in the process of control information transmission is reduced.
Description
technical field [0001] The present invention relates to the resource configuration technology in the mobile communication system, in particular to the method and device for sending control information. Background technique [0002] When the existing system sends control information for users, it needs to configure the control channel used. There are two specific configuration methods: one is static, that is, the time-frequency resource where the control channel is located is fixed, and correspondingly, The receiving end can acquire it at a fixed time-frequency position, and the other is dynamic, that is, the time-frequency resource where the control channel is located can be changed. Every time it changes, an update instruction message needs to be sent so that the receiving end can accurately The time-frequency position receives control messages. [0003] For the above-mentioned static control channel configuration method, for the same-frequency networking system, the posit...
