Problems solved by technology

[0006] However, in the prior art, a radio network controller (Radio Network Controller, RNC) cannot allocate E-DPCCH power boost resources for a radio link of a UE with E-DPCCH power boost capability during resource configuration
As a result, even if the UE has the E-DPCCH power boost capability, it cannot use the power boost feature of the E-DPCCH for channel estimation, and there will still be problems of inaccurate channel estimation and poor data demodulation performance during high-speed data transmission.

no. 8 example

[0132] The tenth embodiment of the present invention will be specifically described below with reference to the eighth embodiment of the present invention. The tenth embodiment provides another Node B, and the Node B includes:

[0133] The receiving module is configured to receive the notification of the configured related resources sent by the RNC;

[0134] A sending module, configured to send the capability information of the Node B to the RNC, where the capability information does not include whether the Node B has the E-DPCCH power boost capability;

[0135] The processing module is configured to configure resources used by the Node B for channel estimation for the UE.

[0136] In the sending module, when the Node B does not have the E-DPCCH power boost capability, and the E-DPCCH power boost related parameters are received, the RNC 710 sends an RL establishment failure message, and the message carries the failure reason. Wherein, the failure reason indicates that Node B d...

Abstract

The application discloses a method and system for resource allocation. The method includes: a base station sends first indication information, which indicates whether the base station supports an enhanced-dedicated-channel dedicated-physical-control-channel power raising capability, to a wireless network controller; the wireless network controller receives second indication information, which indicates whether UE supports the enhanced-dedicated-channel dedicated-physical-control-channel power raising capability, from the UE; and if both of the base station and the UE support the enhanced-dedicated-channel dedicated-physical-control-channel power raising capability, the wireless network controller allocates resources, which adopt the enhanced-dedicated-channel dedicated-physical-control-channel power raising capability to perform channel estimation on the UE, for the base station. Through the method and the system, a network side is capable allocating resources of the base station correctly and if both of the base station and the UE support the channel power raising capability, the base-station resources which adopt the channel raising capability to perform channel estimation are allocated for the UE so that a bit error rate under high-speed data transmission is reduced.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a resource allocation method, device and system. Background technique [0002] In the field of mobile communications, with the development of various services, users have higher and higher requirements for data transmission speed. In order to support higher rate data services, lower latency, higher throughput and spectrum utilization, two new technologies are proposed, High Speed ​​Downlink Packet Access (HSDPA) and High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) technology. [0003] The HSUPA technology introduces new physical channels, including the E-DCH Dedicated Physical Data Channel (E-DPDCH, E-DCH) for carrying the uplink data information of the Enhanced Dedicated Channel (E-DCH, Enhanced Dedicated Channel). Dedicated Physical Data Channel), and an E-DCH dedicated physical control channel (E-DPCCH, E-DCH Dedicated Physical Control Ch...
