Problems solved by technology

[0005] The problem existing in the existing delivery technology is that when the NodeB sends the resource (including code channel, time slot, power) authorization to the UE through the E-AGCH (E-DCH Absolute Grant Channel) channel, only one power control instruction, since the minimum time unit applicable to an E-AGCH scheduling is a TTI (transmission time interval), this is reasonable for the case where the TTI period is the same as the frame length (or subframe length), such as 5ms TTI, but for the length In the case where several TDD frame lengths (or subframe lengths) are the same, such as 20ms TTI, in order to achieve a better power control effect, multiple TPCs need to be issued in one TTI, but the current technology cannot support this function, and the limitation The further improvement of the system throughput

Embodiment Construction

[0024] The core idea and various preferred embodiments of the present invention will be further described and illustrated in detail below with reference to the accompanying drawings.

[0025] The present invention provides a method for issuing multiple power control commands through virtual scheduling. Its core idea is: to fully borrow the existing method of issuing a power control command within a transmission time interval to achieve a long transmission time Issue multiple power control commands within intervals.

[0026] figure 2 It is a flow chart of the steps of the method of the present invention, such as figure 2 Shown, the inventive method comprises 2 steps:

[0027] Step 1: The base station allocates service resources and continuously issues power control commands;

[0028] Step 2: The base station sends confirmation or non-confirmation information to the terminal.

[0029] image 3 It is a schematic diagram of the power control instruction issuing method in th...

Abstract

The invention discloses a method for distributing a plurality of power control instructions via the virtual scheduling, which is characterized in that the invention comprises the following steps: step1: the base station collocates the service sources and continuously distributes power control instructions; step 2: the base station distributes the confirmed or disconfirmed message to the terminal.The method can make full use of the current practice of transmitting one power control instruction within a transmission time interval to realize the distribution of a plurality of power control instructions within a longer transmission time interval, which increases the power control accuracy and system throughput and is conducive to realization within the framework of the prior technology.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for issuing multiple power control instructions through virtual scheduling in a TDD system. Background technique [0002] In the HSUPA (High Speed ​​Uplink Packet Access) technology, the dispatching function is delegated to the NodeB (base station), so that the load information of the cell can be used more accurately and in real time, and the uplink air interface resources can be more fully utilized. The service based on NodeB scheduling is called the scheduling service. Before the UE (terminal) transmits data, it first sends a scheduling request through the E-RUCCH (E-DCH random access uplink control channel) channel. See figure 1 , the NodeB allocates resources for the UE according to the UE's scheduling request and the resource status of the cell, and sends the authorized resources (including code channels, time slots, and power) through the E-AGCH (E-D...
