Embodiment Construction

[0023] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principle of the present invention.

[0024] Technical conception of the present invention: the check for the CRC16 of the FP frame of HS-DSCH channel in the existing TD-SCDMA system is unselectable, each FP frame all needs to carry this CRC16 field, and when the transmission error rate of Iub mouth is very high When it is low, the CRC16 field causes a waste of Iub port bandwidth, and also brings CRC calculation load to the FP protocol processing module of the sender-receiver, especially when processing HSDPA and HSPA+ downlink data services, the data length at this time is in the About 3000bits. The present invention proposes the CRC configuration method of TD-SCDMA system based on the FP ...

Abstract

The invention relates to a CRC configuration method of a TD-SCDMA system, and belongs to the technical field of wireless communication. The method is applied to an RNC and comprises the following steps: the RNC configures a payload CRC indication field for an HS-DSCH channel through NBAP signaling; the RNC indicates whether an FP frame of the HS-DSCH channel carries a payload CRC according to thepayload CRC indication field; and the RNC sends the FP frame of the HS-DSCH channel to a Node B, so that the Node B judges whether to perform check analysis of the payload CRC on the FP frame according to the payload CRC indication field. By adoption of the CRC configuration method provided by the invention, the problem that the existing HSDPA and HSPA+ downlink FP frames must carry payload CRC16fields and cannot be dynamically controlled, resulting in the waste of a Iub interface transmission bandwidth and the processing capability of CRC16 check calculation, is solved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a CRC configuration method of an FP frame based on Iub interface signaling in a TD-SCDMA system. Background technique [0002] At present, the signaling configuration information of the HS-DSCH (High Speed ​​Downlink Shared Transport Channel: High Speed ​​Downlink Shared Channel) channel specified in the 3GPP protocol does not configure whether the FP frame carries the CRC16 check IE (Information Element), that is, the HS-DSCH channel CRC16 check must be carried in the FP frame. The HSDPA and HSPA+ downlinks of the TD-SCDMA system are high-speed services, the processing load of the sender and receiver of the FP protocol unit is very large, and the Iub interface (the interface between RNC and NB in ​​TD-SCDMA) is wired transmission, so the reliability of the transmission Very high, there is no need to carry CRC16 check in every FP frame. [0003] In the prior art,...
