Problems solved by technology

The transmission method of the existing technology still retransmits sub-stream B and sub-stream C or adopts the same maximum number of retransmissions as sub-stream A, etc. These are obviously a large waste of transmission resources

Abstract

The embodiment of the invention provides a data transmission method and data transmission equipment. Transmission resources are saved. The method comprises the following steps of: receiving an indication about a transmission mode adopted for a transport block from a high protocol layer, wherein the high protocol layer is a sub-layer above a physical layer; and transmitting the transport block to a receiver, and informing the receiver of the transmission mode adopted for the transport mode, wherein the transmission mode corresponds to the indication. By the method and the equipment, different data can be transmitted according to different transmission modes, for example, cyclic redundancy check (CRC) for transport blocks by which the CRC is not required is avoided, or unnecessary retransmission for transport blocks not to be retransmitted in a frame of data is avoided; and therefore, the processing resources of the receiver can be saved, and the transmission sources of a network also can be saved, such as power sources, code sources and the like.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a data transmission method and a sending device. Background technique [0002] With the rapid development of communication technology, Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access), as one of the mainstream technologies of the third generation mobile communication system, has been widely researched and applied worldwide. At present, WCDMA already has multiple versions such as the 99th version (Release99, R99), the 4th version (R4, Release4) and the 10th version (R10, Release10). [0003] In order to increase the data transmission rate and meet different needs, WCDMA adopts high-speed packet access (HSPA, High Speed ​​Packet Access) technology, including high-speed downlink packet access (HSDPA, High Speed ​​Downlink Packet Access) technology and high-speed uplink packet access (HSUPA, High Speed ​​Uplink Packet Access) technology.
