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 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.

[0044] The core of the present invention is that when UE has no data to transmit and only needs to send SI to Node B, it uses E-DPCCH to send control information including part of SI to Node B, and sends the remaining part of SI to Node B through E-DPDCH ; The Node B reassembles part of the 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 reassembled SI.

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

[0046] like Figure 8 As shown, in step 810, the UE judges whether it is currently impossible or unnecessary to send user data, ...

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 invention relates to mobile communication technology, in particular to an E-DCH data transmission method. 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). [0004] Among them, HSDPA was introduced i...
