Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] The first embodiment of the embodiment of the present invention relates to the scheduling method of the high-speed uplink packet access technology. The embodiment of the present invention is described by taking the WCDMA system as an example, but it is not limited thereto.

[0019] The specific process is shown in Figure 1.

[0020] Step 101: at the initial moment of the RTWP measurement period, calculate the uplink load of the cell according to the measured value of the RTWP;

[0021] In this embodiment, the RTWP measurement period is 100 ms as an example for illustration. The WCDMA system regularly outputs a timing signal every 100ms, and the Node B obtains the measured value of the RTWP of the cell, and calculates the Cell U...

Abstract

The invention relates to the wireless communication field, disclosing a scheduling method and device of supporting high-speed uplink packet access (HSUPA) technique, improving scheduling performance of Node B. In the invention, at the initial time of a RTWP (Received Total Wide band Power) measuring cycle, and according to the RTWP measured value, calculating cell uplink load; in the RTWP measuring cycle, regularly updating the cell uplink load; according to the updated cell unlink load, making HSUPA scheduling. And the invention also provides a scheduling device for HSUPA, comprising calculating module, updating module and scheduling module. And the invention can shorten the cycle of updating cell unlink load, and improve cell uplink load estimating realtimeness so as to improve HSUPA scheduling performance.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the dispatching technology of the high-speed uplink packet access technology. Background technique [0002] HSUPA (High Speed ​​Uplink Packet Access-High Speed ​​Uplink Packet Access Technology) is another important new feature in WCDMA (Wide-band Code Devision Multiplke Access-Wideband Code Division Multiple Access). R99 feature, which introduces the uplink data inner loop confirmation mechanism between UE (User Equipment-user terminal) and Node B (WCDMA system base station), HARQ (Hybrid Automatic Repeat Request-hybrid automatic repeat request), MAC-e (processing The media access layer entity of E-DCH.) Scheduling, improving the physical channel capacity limit capability available to users, short frame mechanism and other technologies. The uplink data inner-loop confirmation mechanism between UE and Node B has changed the original method that can only be confirmed by RNC ...
