Embodiment Construction

[0034] Below, combined with figure 1 The method for allocating wireless resources in the communication system of the present invention will be described in detail.

[0035] Generally, the number of code channels for demodulation of each time slot can be designed according to the maximum supportable capacity, for example, in a TD-SCDMA system, the maximum number of code channels supported by each time slot is designed to be 16, so that it is possible to demodulate all The ability to configure code channels, but for the design of 12 code channels, the design and actual calculation amount cannot be reduced because of the reduction of the number of code channels, because other control channels may still be configured on this time slot, so this can only The complexity of judgment and the complexity of design are increased, so it is not necessary to design differently for the number of code channels. For example, considering that the HS-SCCH channel and the accompanying dedicated p...

Abstract

The invention discloses a method of distributing the wireless resource in the communication system, which comprises the following steps: (A) reporting the supporting HSDPA business ability grade information to the network side by the upgoing signaling of the terminal; (B) analyzing the ability grade information reported by the terminal by the network side and regarding the time slot number reported by the terminal and the time slot resource used by the plot as the resource distribution limit standard; (C) sending the business data to the terminal according to the resource distribution limit standard by the network side. The invention avoids the waste, which makes the resource distribution method of the network side more rational and simpler and is fit for the characteristic of TDD.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for allocating wireless resources in a communication system. Background technique [0002] In the Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system, it is necessary to consider the ability of the terminal (UE) to report the High Speed ​​Downlink Packet Access (HSDPA) and the network side of the resource allocation process. [0003] In HSDPA technology, different terminals in the system realize high-speed downlink data services by sharing channels, mainly using Hybrid Automatic Repeat request (HARQ) and adaptive coding and modulation (Adaptive Modulation and Coding, AMC) technology To achieve real-time scheduling and adjustment of resources. Different terminals support services in different levels due to their own limitations. Therefore, the radio network controller (Radio Network Controller, RNC) and NodeB need to know the specific support...
