Embodiment Construction

[0022] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] For the CDMA system, after the random access time of the UE, some code channel fragments will appear, and there will be multiple physical channels with large SF. Due to the capability limitation of the UE, when the UE transmission bandwidth is satisfied, Under the following circumstances, it is necessary to allocate a physical channel with a small SF to the UE as much as possible. For the physical channel selection of high-speed services, there may not be a physical channel with a corresponding spreading factor that meets its needs. At this time, the code resource integration process can be triggered actively to reduce The discreteness of the code table improv...

Abstract

The invention provides a track integration method and a device thereof. The method comprises the steps of performing statistic calculation of the occupation of a maximal spreading factor layer, and constructing a set of occupied tracks; performing set partition of the maximal spreading factor layer to obtain a set to be selected; selecting the set to be selected with the minimum number of users as an adjustment source, and considering the users therein as users to be adjusted; and performing physical channel reconfiguration to the users to be adjusted to reallocate physical resources. The inventive method and the device can obtain physical channels meeting requirements via integration, thereby remarkably improving the utilization ratio of physical resources.

Description

technical field [0001] The present invention relates to the field of mobile communications, and more specifically, to a code channel integration method and a code channel integration device, which are used when the code channel resource meets the service allocation but the code channel corresponding to the spreading factor does not meet the service allocation condition , to perform code channel integration. Background technique [0002] In the third-generation mobile communication system with code division multiple access, physical channels are identified by combinations of spreading codes. The following takes the TD-SCDMA time division synchronous code division multiple access system as an example to illustrate. In TD-SCDMA, every 10ms on each specified carrier frequency is a frame, each frame is divided into two subframes, the structure of the two subframes is the same, and each subframe is divided into 7 regular time slots and In the 3 special time slots, the user’s bus...
