Problems solved by technology

[0005] Therefore, when the channel code resource allocation method in the prior art allocates channel code resources for HS-SCCH, or E-AGCH and E-HICH / E-RGCH, the corresponding channel code resources are statically allocated completely according to the RNC configuration requirements, As a result, the maximum number of available channel codes for HS-PDSCH may be only 14, and the actual utilization rate of channel code resources and the throughput rate of users also decrease.

Abstract

The embodiment of the invention discloses a distribution method of channel code resources and a base station. The method comprises the following steps: receiving a resource configuration notification message sent by a wireless network controller, wherein the resource configuration notification message carries a high-speed shared control channel (HS-SCCH), an enhanced dedicated channel (E-DCH) absolute grant channel (E-AGCH), or an E-DCH hybrid automatic repeat request (ARQ) indicator channel / E-DCH relative grant channel (E-HICH / E-RGCH) which requires to configure the channel code resources; and according to the channel resource occupation situation in a cell, distributing the channel codes for the HS-SCCH, the E-AGCH or the E-HICH / E-RGCH in the cell as required. The base station comprisesa receiver module and a distribution module. The embodiment of the invention dynamically distributes the channel code resources for each channel in the cell according to the practical situation, thusimproving the practical utilization ratio of the channel code resources.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method for allocating channel code resources and a base station. Background technique [0002] In a Wideband Code Division Multiple Access (WCDMA) system, an Orthogonal Variable Spreading Factor (OVSF) channel code is usually used to realize the dynamic distribution of system bandwidth resources. Allocation, and ensure the orthogonality between the signals sent to different users in the same cell, that is, the signals sent to different users will not interfere with each other. However, the channel code resources of the cell are very limited, figure 1 It is a schematic diagram of the spanning tree structure of the OVSF channel code in the prior art, such as figure 1 As shown, there are at most 16 spreading factor (Spreading Factor; SF for short) 16 channel codes in a cell. [0003] According to the 3rd Generation Partnership Project (the 3 rd The Gener...
