Problems solved by technology

[0018] In actual application, the above scheme has the following problems: the user terminal and the base station node cannot start and stop the DTX transmission of the uplink DPCCH synchronously, and cannot specify different uplink DPCCH activations pattern
[0019]The main reason for this situation is that in the existing DTX transmission technology of uplink DPCCH, only the user terminal decides when to start the uplink DPCCH according to the data transmission situation The lack of effective signaling to inform the base station node of the start of the DTX transmission of the uplink DPCCH, so that the base station node cannot determine the exact time when the user terminal starts the DTX transmission of the uplink DPCCH, although the activation pattern of the uplink DPCCH is known to the user terminal and the base station node information, the base station node still cannot operate synchronously with the user terminal according to the known uplink DPCCH activation pattern

Embodiment Construction

[0046] 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.

[0047] The core of the present invention is that when there is no data to be transmitted to the base station node, the user terminal sends control information indicating that DTX is started to the base station node, as shown in FIG. DTX is performed, and after receiving the control information, the base station node also discontinuously receives the uplink DPCCH at a preset time according to a corresponding preset activation pattern.

[0048] The core of the present invention has been briefly described above, and the method for transmitting the uplink DPCCH according to the first embodiment of the present invention will be described in detail below.

[0049] As shown in FIG. 9, in step 910, the user terminal determines whether there is data to be transmitted withi...

Abstract

The method can make the base station node and user end capable of synchronously realizing the discrete transmission of uplink DPCCH. In the invention, when user end has no data to upload to base station, it sends the control message used for starting discrete transmission through E-DPCCH; the base station synchronizes its own discrete receiving function with the DTX of user end; wherein, the control message can be gotten from the idle value and be a designated value of E_TFCI in the newly-added data transmission block assembly.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a transmission method of an uplink dedicated physical control channel. 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. Different from the scheduling and retransmission of data packets in the R99 version, which is controlled by the Radio Net...
