Problems solved by technology

[0017] In practical applications, the above scheme has the following problems: the spare bits are not fully utilized, which reduces resource utilization
Obviously, the "RSN" field and the "Happy" bit field are not used when the SI report is sent separately on the E-DPDCH, and the existing technology does not make full use of these three bits, so from the perspective of resource utilization not optimal

Embodiment Construction

[0043] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] The core of the present invention is that when the UE has no data to transmit and only needs to send the SI to the Node B, it uses the E-DPCCH to send the control information including part of the SI to the Node B, and sends the remaining part of the SI to the Node B through the E-DPDCH. ; The Node B reorganizes the partial SI in the received control information and the remaining part of the SI in the E-DPDCH into a complete SI, and schedules the current E-DCH physical channel according to the reorganized SI.

[0045] The core of the present invention is briefly described above, and the first embodiment of the present invention is described in detail below.

[0046] As shown in FIG. 8 , in step 810, the UE determines whether it is currently unable or unn...

Abstract

The invention is used for improving the utilization rate of radio resources when UE independently sends SI. In the invention, when UE only needs to send SI to Node B, it transmits a part of SI content through 'RSN' and / or 'Happy' bit field on E-DPCCH, and meantime, uses a specific value of E-TFCI bit field to flag the 'RSN' and / or 'Happy' bit field in order to indicate that a part of SI content is transmitted and to indicate that what transmitted on the E-DPDCH is the rest of SI content.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an E-DCH data transmission method. Background technique [0002] The 3rd Generation Partnership Project ("3GPP"), as an important organization in the field of mobile communication, has promoted the standardization of the third generation mobile communication ("The Third Generation", "3G") technology. The bearer of uplink and downlink services in the version is based 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. The scheduling and retransmission of data packets in HSDPA and HSUPA are controlled by a base station node (Node B). [0004] Among them, HSDPA, as a downlink high-speed data packet access technology, was introduced into t...
