Problems solved by technology

From this large and small control strategy, it can be seen that if the current step size of each service in the combined service is different, the control of the outer loop power according to this large and small control strategy cannot satisfy the convergence of all services. On the expected target value, that is, it cannot meet the performance requirements of each business
[0022] In addition, for the processing of a single service, the above prior art method does not have problems when the number of received TB blocks remains unchanged, but the defect of this method is that when the adjustment period is large and the number of received TB blocks fluctuates greatly, that is During the adjustment period, it is more likely tha

Example Embodiment

[0063] The core idea of ​​the present invention is: for a single business, in the outer loop adjustment timer, through the calculation of the current business block error rate, it is judged whether the current business needs to be adjusted, if necessary, according to the current block error rate, TB block Calculate the current step length and adjust the target signal-to-interference ratio. The method of the present invention satisfies the convergence of control and also saves resources;

[0064] For combined services, first randomly select one of the combined services as the current service. In the control object change timer, by calculating the BLER of other services, determine whether it is within the allowable range of error, if it is within the allowable range of error If the current block error rate differs from the target block error rate, the business with the largest difference between the current block error rate and the target block error rate is changed to the current b...

Abstract

The method processes services of having process requirements in composition services so as to guarantee that each service in composition services can be met requirements of service performances, and save resources. Improving algorithm of adjusting step length, the invention can converge BLER to setup target value finally for services needed to carry out adjustment even if major fluctuation is existed in number of TB block received in adjustment period so as to assure controlling effect. The invention also discloses method for dynamic adjusting outer ring power control of single service.

Description

technical field [0001] The invention relates to outer loop power control technology, in particular to a dynamic adjustment method for outer loop power control. Background technique [0002] In the code division multiple access (CDMA) system, at present, in the evaluation of physical channel data communication indicators, one of the important evaluation indicators is the block error rate (BLER), BLER refers to the wrong TB in the received transport block (TB) The proportion of blocks. In particular, in the combined service, since the combined service means that a terminal device activates multiple services at the same time, and these activated services are multiplexed and mapped to the same physical channel according to certain rules, the evaluation of physical channel data communication Particularly important. [0003] Since the wireless environment changes in thousands of ways and cannot be predicted, in order to evaluate and guarantee BLER requirements, a mechanism needs...
