Problems solved by technology

[0027] In practical applications, the above scheme has the following problems: the performance of E-DCH scheduling is low, and there is uncertainty in the value of the Serving_Grant parameter
However, since the "Zero_Grant" of the Serving_Grant parameter is a non-numeric value at this time, in this case, there is uncertainty in the value of Serving_Grant

Embodiment Construction

[0065] 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.

[0066] In the process of updating the Serving_Grant parameter value of the RG command of the E-DCH non-serving RL according to the present invention, when the Serving_Grant of the current TTI=Zero_Grant is allowed, the UE still responds to the RG command of the E-DCH non-serving RL with the value "DOWN", namely The condition for the reduction of the Serving_Grant parameter value controlled by the RG command of the E-DCH non-serving RL is that a certain TTI receives at least one RG command with the value of "DOWN" for the E-DCH non-serving RL. Regardless of the value of the Serving_Grant parameter of the current TTI, in this way, for the situation where the Serving_Grant parameter of the current TTI is "Zero_Grant", the timing length of a Non_Serving_RG_Timer after ...

Abstract

The related control method for business authorized parameter on E-DCH comprises: if Serving_Grant=Zero_Grant in current TTI, receiving RG command 'DOWN' from E-DCH non-business RL, setting Maximum_Serving_Grant as the value at least lower one-class relative to value in scheduling table of reference_ETPR, and setting Non_Serving_RG_Timer to limit value of Serving_Grant not beyond the Maximum_Serving_Grant in pre-set time, wherein the reference_ETPR is the power ratio of E-DPDCH and DPCCH of TTI in one HARQ process.

Description

Technical field [0001] The present invention relates to the field of mobile communications, and in particular to a technology for controlling service authorization parameters in an enhanced dedicated channel (Enhanced Dedicated Channel, "E-DCH" for short). Background technique [0002] As an important organization in the field of mobile communications, the 3rd Generation Partnership Project ("3GPP") promoted the standardization of the third generation mobile communications (The Third Generation, "3G") technology. Its early agreements 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 constantly evolving. High Speed ​​Downlink Packet Access (HSDPA) and High Speed ​​Uplink Packet Access (HSUPA) are important evolutions of 3G technology. The scheduling and retransmission of data packets in HSDPA and HSUPA are controlled by the base station node (Node B). [0004] ...
