Abstract

The invention discloses a data transmission method. The method comprises the following steps that: when a base station Node B sends control information to terminal UE through a high-speed sharing control channel HS-SCCH, the HS-SCCH carries physical resource information of a high-speed physical downlink sharing channel HS-PDSCH needed to be monitored by the UE, a UE identification ID, a PTR pointer and transmission frequency, and also carries a modulation mode instruction, a transmission block size, an HS-SCCH circulation serial number HCSN, an incremental redundancy version number, a high-speed sharing information channel HS-SICH instruction, a feedback mode, a monitoring time instruction, and one or more kinds of control information in resource adjusting time. The invention also discloses a data transmission device and a system. The method, the device and the system can flexibly change the control information of data transmission.

Description

technical field

[0001] The present invention relates to data transmission technology, in particular to a data transmission method, device and system. Background technique

[0002] In High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) technology, the High Speed ​​Shared Control Channel (HS-SCCH, Shared Control Channel for HS-DSCH) is used to carry the High Speed ​​Physical Downlink Shared Channel (HS-PDSCH, High Speed ​​Physical Downlink SharedChannel) scheduling and control information, for each HS-PDSCH transmission time interval (TTI, Transmission Time Interval), the downlink control information of the terminal (UE) carried by HS-SCCH is shown in Table 1, including: transmission format resources Combination (TFRI), generally 13 bits (bit), indicates the transmission format of the subsequent HS-PDSCH, including the time slot of HS-PDSCH, and code channel information; modulation method (1 bit); transport block size (TBS, Transport Block Size), ...
