Abstract

Provided is a transmission control method in a wireless communication system. In the wireless communication system, a plurality of data blocks can be transmitted from a sending device with a plurality of sending antennas to a receiving device. The transmission control method comprises the following steps that in the receiving device, course information with no competition between the data blocks is sent to the receiving device through a control channel; the data blocks are sent to the receiving device; and in the receiving device, the data blocks and the course information are received from the sending device, wherein the course information is serial number information.

Description

[0001] This application is based on Article 42 of the Detailed Rules for the Implementation of the Patent Law. It is the application date of October 27, 2006, and the application number is 200680056206.X. Divisional application. technical field [0002] The present invention relates to a transmission control method in a wireless communication system, in particular to a retransmission control technology suitable for MIMO (Multi Input Multi Output) transmission. Background technique [0003] Regarding mobile communication systems such as mobile phones, the third-generation method based on CDMA (Code Division Multiple Access, Code Division Multiple Access) has already begun to serve, and is promoting OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division) Research on a next-generation mobile communication system that realizes faster communication based on the Multiple Access) method (see Non-Patent Document 1 described later). [0004] Therefore, M...
