Embodiment Construction
[0066] When a user uses multi-carrier HSUPA, in order for the UE to clearly know whether there is a secondary frequency point in the neighboring cell that is the same as its own HSUPA frequency point, the radio network controller instructs the UE neighboring cell secondary frequency point through a radio resource control (RRC, RadioResource Control) message The same frequency situation. After the UE knows the information of the neighboring cells, it needs to include the relevant neighboring cells when reporting the SNPL at the multi-carrier HSUPA frequency point.
[0067] This embodiment provides a configuration system for high-speed uplink packet access to adjacent cells of the same frequency in a multi-carrier system, including RNC, UE and NodeB;
[0068] The RNC is used to configure the same-frequency information of multi-carrier HSUPA for the UE and send it to the UE;
[0069] The UE is configured to perform neighbor cell measurement and SNPL reporting according to the ob...

The invention provides a system and method for configuring a shared-channel neighbour cell of high speed uplink packet access in a multi-carrier system. The method comprises the steps: a wireless network controller configures shared-channel information of multi-carrier high speed uplink packet access (HSUPA) to user equipment and sends the shared-channel information to the user equipment; and the user equipment performs neighbour cell measurement and reports serving and neighbour cell pathloss (SNPL) according to the obtained shared-channel information of the multi-carrier HSUPA. By using the technical scheme of the invention, the user equipment can correctly report the SNPL information when the multi-carrier HSUPA works, therefore, a node base station can be used for distributing proper resource to the user equipment according to the SNPL information so as to improve service rate and reduce interference.
