[0017]3) The design of this scheme needs to know in advance the corresponding SIR of the channel when the service quality is satisfied, because there are many types of service combinations, and the BLER / frame error of each service rate (FER) setting is not static, so this scheme is less practical

Embodiment Construction

[0102] 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 with reference to the accompanying drawings and examples.

[0103] The main idea of ​​the present invention is first to independently evaluate the service quality of the channel corresponding to each service in the combined service by means of short-term and long-term combination, and obtain an adjustment method for the channel corresponding to each service in the combined service, and then, comprehensively Considering the adjustment mode of each channel, the target SIR of the combined service is adjusted within the allowable adjustment range of the target SIR of the combined service.

[0104] figure 2 It is a schematic flowchart of the method for performing outer-loop power control on combined services in the present invention. see figure 2 The method firstly executes steps 201 to 203 on the channel corresp...

Abstract

The invention discloses a method for outer-loop power control of integrated services. The method carries out step A to step C of the following steps for a corresponding communication channel of each service of the integrated services: A, calculating a long term statistical service quality value of a communication channel according to verification results of data received in recent period by the communication channel; B, estimating short-term service quality of the communication channel according to the verification results of data received currently by the communication channel and a target service quality value and determining a short-term adjustment mode of the target SIR of the communication channel; C, determining a long-term adjustment mode of the target SIR of the communication channel according to the long-term statistical service quality value of the communication channel, the short-term adjustment mode and the target service quality value; and D, adjusting a target SIR of theintegrated services according to the long-term adjustment mode, the permitted adjustment ranges of the target SIR of the integrated services. The invention also discloses a device for the outer-loop power control of the integrated services. The method and the device can effectively improve performance of outer-loop power control with relatively low implementation complexity.

Description

technical field [0001] The invention relates to the power control technology in the wireless communication system, in particular to a method and device for controlling the outer loop power of combined services. Background technique [0002] A code division multiple access (CDMA) communication system is a code division multiplexing system, and the transmitted signal of one user is interference to other users in the system. In order to make the system reach the maximum capacity, each user needs to transmit with the minimum power under the condition of satisfying the service quality, so power control needs to be performed on the data sender. [0003] Power control is divided into open-loop power control and closed-loop power control. Among them, the open-loop power control determines the power of the first data transmission of the physical channel according to the path loss; the closed-loop power control is jointly completed by the outer-loop power control and the inner-loop p...
