Embodiment 1

[0031] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a method for reducing uplink interference in the present invention, specifically including the following steps:

[0032] Step 101, the local cell receives an adjustment instruction sent by a neighboring cell, and the adjustment instruction is sent when the neighboring cell determines that the first user accesses the network of the neighboring cell.

[0033] Since the uplink rate of the first user in the neighboring cell is mainly affected by the uplink transmission power of the local cell; therefore, a method for reducing uplink interference proposed by the embodiment of the present invention, that is, after the first user enters the neighboring cell, it can pass Reduce the total uplink transmission power of the local area to reduce the uplink external interference of the first user; wherein, the first user may be a member user of a neighboring cell, or a test user of a neighboring cell, and t...

Embodiment 2

[0040] The embodiment of the present invention describes an adjustment method for reducing the uplink transmission power of the second user. refer to figure 2 , which shows a flow chart of steps of another embodiment of a method for reducing uplink interference in the present invention, specifically including the following steps:

[0041] Step 201, the local cell receives the adjustment instruction sent by the neighboring cell.

[0042] When the neighbor cell determines that the first user accesses the network of the neighbor cell, in order to increase the uplink rate of the first user, it can send an adjustment command to the local area so that the local area can reduce its total uplink transmission power; after receiving the adjustment command, the local cell can Then perform a related operation of reducing the total uplink transmit power.

[0043] Step 202, judging whether there is a second user whose uplink performance parameter satisfies the adjustment condition in the...

Embodiment 3

[0058] The embodiment of the present invention describes the adjustment manner of removing the second user from the network in the local area. Specific reference image 3 , image 3 It shows a flow chart of steps of another embodiment of a method for reducing uplink interference in the present invention, which specifically includes the following steps:

[0059] Step 301, the local cell receives the adjustment instruction sent by the neighboring cell.

[0060] Step 302, judging whether there is a second user whose uplink performance parameter satisfies the adjustment condition in the local area; if yes, execute step 303; if not, execute the end step.

[0061] Steps 301-302 are similar to the above-mentioned steps 201-202, and will not be repeated here.

[0062] Step 303, remove the second user from the local area network.

[0063] In the embodiment of the present invention, after the second user is determined, the second user is directly removed from the network in the local ...

Abstract

An embodiment of the invention provides a method and device for reducing uplink interference. The method comprises the following steps: a local cell receiving an adjustment instruction sent by an adjacent cell, wherein the adjustment instruction is sent by the adjacent cell when determining that a first user is connected to a neighborhood network; judging whether the local cell has a second user,the uplink performance parameters of whom meet adjustment conditions; and when determining that the local cell has the second user, reducing uplink emission total power of the local cell by adjustingthe second user to reduce interference on uplink rate of the first user. The method can reduce interference on uplink rate of the adjacent cell user by reducing the uplink emission total power of thelocal cell, thereby improving uplink rate of the first user.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for reducing uplink interference. Background technique [0002] In the fourth-generation mobile communication system, the user's uplink rate is mainly affected by uplink external interference; each base station in the local area has one or more adjacent base stations, so that the uplink rate of the base station in the local area is affected by its neighbors. interference from base station users. [0003] Each base station has member users and ordinary users. Among them, the base station needs to ensure the uplink rate of member users. In the prior art, the method of randomly assigning physical resource blocks to the uplink users of the base station in the local area cannot well reduce the adjacent The interference of base station users on the uplink rate of member users makes the effect of improving the uplink rate of member users poor.
