[0062] In this embodiment, the RNC configures the maximum allowable uplink transmission power for the UE according to the carrier. Next will refer to image 3 Describe in detail, including the following specific steps.

[0063] S302, the RNC requires the Node B to establish an enhanced uplink for the UE, wherein the configuration of the maximum uplink transmission power of the UE is added, wherein the RNC configures the maximum transmission power defined by the UE capability for the Node B, and when this parameter provides resource scheduling for the Node B, Quota reference for the UE's total transmit power. Both the power authorization and the closed-loop power control process of Node B require to know the configuration information of the reference expected received power. Since the interference of each carrier is different, the RNC will distinguish the carrier and configure the reference expected received power of the E-PUCH channel on each carrier. .

[0077] In this embodiment, the RNC configures the total maximum allowable uplink transmission power for the UE, and then uses image 3 Taking it as an example for detailed description, the following specific steps are included.

[0078] S302. The RNC requests the Node B to establish an enhanced uplink for the UE, and configures the smaller value of the total maximum allowable uplink transmission power of the UE and the maximum transmission power defined by the UE capability to the Node B. This parameter is the limit reference of the UE's total transmit power when Node B provides resource scheduling. Both the power authorization and the closed-loop power control process of Node B in the open loop require the configuration information of the reference expected received power. Since the interference of each carrier is different, the RNC will configure the reference expected received power of the E-PUCH channel on each carrier by distinguishing the carrier . Configured during NB...

Abstract

The invention provides a method for distributing power resource of a multi-carrier enhanced uplink, which includes the steps that: a wireless network controller configures maximum uplink transmitted power of a user terminal for a base station; the wireless network controller configures allowable maximum uplink transmitted power for the user terminal and expected reference received power of each carrier; the user terminal reports dispatching information including remained power of each carrier; the base station, after receiving the reported dispatching information from the user terminal, distributes power for each carrier according to the reported dispatching information and the maximum uplink transmitted power. Therefore, by adopting the method of the invention, the remained power of each carrier of UE can be concerned without transcending the capacity of the UE; furthermore, the method of the invention can be applied to a TD-SCDMA system.

Description

technical field [0001] The present invention relates to the field of wireless communication, more specifically, to a method for allocating multi-carrier enhanced uplink power resources. Background technique [0002] The enhanced uplink access system is generally called HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access), which aims to improve the efficiency of the uplink through advanced technology to effectively support web browsing, video, multimedia information and other information based on IP business. [0003] Currently, 3GPP (Third Generation Partnership Project Organization) has completed the standardization work of TD-SCDMA enhanced uplink access system. Applicable to single carrier TD-SCDMA system. A transport channel E-DCH (Enhanced Uplink Dedicated Transport Channel) is added to the enhanced uplink access system, and the TTI (Transmission Time Interval) of the E-DCH is 5 ms. The packet mapped to the E-DCH transport channel is called MA...
