Problems solved by technology

[0020] In practical applications, the above scheme has the problem of high decoding complexity of Node B
The main reason for this situation is that due to the method of differential transmission of E-DPCCH, in the case of no change in the transmission format, E-DPCCH is not transmitted, so that Node B is forced to need Blind detection is performed, so the decoding complexity of Node B is greatly increased

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] The present invention transmits the E-DCH control information in a discontinuous transmission mode for the E-DPCCH, and when the E-DPCCH suspends transmission, the UE transmits the RSN and "happy" bits to the Node B through the uplink DPCCH, so that the Node B can transmit according to The received RSN and "happy" bits are processed for data processing. Wherein, the time slot format of the uplink DPCCH is shown in Table 1.

Abstract

The invention relates to wideband code division multiple access technology, and discloses a method for transmitting service signals through E-DCH, which not only reduces the occupation of uplink wireless resources by E-DPCCH, but also simplifies the decoding complexity of base station nodes. In the present invention, the E-DPCCH is transmitted in DTX mode, and the RSN and "Happy" bits are transmitted through the DPCCH when the E-DPCCH is suspended for transmission. During the E-DPCCH transmission stage, the DPCCH may or may not transmit the RSN and "Happy" bits at the same time. When transmitting RSN and "Happy" bits through the DPCCH, the TFCI field in the DPCCH #0 or #2 slot format can be used, the FBI field and the TFCI field can also be used in combination, and the newly defined DPCCH slot format can also be used. field.

Description

technical field [0001] The invention relates to wideband code division multiple access technology, in particular to a method for transmitting service signals through E-DCH. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP"), as an important organization in the field of mobile communications, has promoted the standardization of the 3rd Generation Mobile Communications (The Third Generation, referred to as "3G") technology. Its early protocol Both uplink and downlink services in this version are carried on dedicated channels. [0003] With the development of mobile communication technology, 3G technology is also constantly evolving. High Speed ​​Downlink Packet Access (HSDPA for short) and High Speed ​​Uplink Packet Access (HSUPA for short) are important evolutions of 3G technology. Scheduling and retransmission of data packets in HSDPA and HSUPA are controlled by a base station node (Node B). [...
