Problems solved by technology

[0006] 2. Node B cannot obtain information on the interference level of neighboring cells;
[0007] Therefore, the method of reducing authorization in the prior art to solve the problem of uplink interference in the CELL_FACH state is not very targeted, and it will also cause the UE to be reduced in scheduling authorization as long as it is at the edge of the cell, thereby reducing the uplink transmission rate.

Abstract

The invention is applicable to the field of communication, and provides a method for controlling the uplink interference of adjacent cells, UE (user equipment), an RNC (radio network controller) and a base station. The method comprises the following steps: the UE (user equipment) receives a message sent by a network, wherein the message carries the cell information of a first cell, and the first cell is a cell adjacent to the cell at which the UE is located; and when the UE judges that the distance between the UE and the first cell reaches a preset threshold, the UE carries out uplink data transmission according to a preset maximum transmission block length. According to the invention, the uplink data transmission rate can be effectively improved.

Description

[0001] This application claims to enjoy the priority of the invention with the application number 201110170102.4 submitted on June 23, 2011, which is a method for controlling uplink interference in adjacent cells, UE, RNC and base station, and the entire content of which is incorporated by reference in this application . technical field [0002] The invention belongs to the communication field, and in particular relates to a method for controlling uplink interference of adjacent cells, a UE, an RNC and a base station. Background technique [0003] In the 3GPP UMTS R8 version, for UE (User Equipment, user equipment) in idle (idle) mode or CELL_FACH (forward random access channel state) state, in order to reduce the uplink transmission delay and increase the uplink transmission rate, the introduction of The new feature of RACH (Random Access Channel, random access channel) is enhanced. The enhanced RACH enhances the random access of the R99 version, and the enhanced random ac...
