Problems solved by technology

[0014]In practical application, the above scheme has the following problems: when the sum of the required power exceeds the rated power, the cut power is only based on the size of the required power, without considering the The information required by the Quality of Service ("QoS") does not refer to the specific conditions of the terminal, and there is no distinction between different types of channels.
Therefore, Qualcomm's channel power allocation method cannot well meet the needs of system performance improvement.
[0016]The main reason for this situation is that Qualcomm's channel power method only allocates channel power based on the required power, without considering other conditions such as QoS, channel category, etc.

Embodiment Construction

[0048] 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 in conjunction with the accompanying drawings.

[0049] In order to solve the problems of the existing technical solutions, the present invention considers the differences of different services, different terminals, and different channels in practical applications, sets the sub-channel priority to be allocated according to these situations, and then performs channel power allocation with reference to its priority information: When the required power of the sub-channel does not meet the rated power, it is divided into sub-channel groups according to the priority from low to high, and the required power is adjusted in turn to determine the final allocated power. First adjust the low-priority sub-channel group, Until the current sub-channel group just meets the rated power after the adjustment, the subsequent sub-ch...

Abstract

This invention discloses a method for distributing channel powers in a third generation mobile communication system. When the sum of required power of channels surpasses a rated power, the required power is regulated to determine the final distribution power to be in conformity with the rated power. In this invention, PRI is designed to subsystems of different kinds, different terminals and different services in terms of its distribution power, sub-channel sets are divided according to the degrees of PRI and the regulation sphere is set in terms of the actual situation and the required power is adjusted to the sub-channel sets in the sphere to determine the final distribution power and the required power is adjusted from the low PRI to the high till meeting the rated power and the corresponding PRI is set according to the QoS requirement and importance of the sub-channels.

Description

technical field [0001] The invention relates to the third-generation mobile communication technology, in particular to a channel power allocation method in the third-generation mobile communication system. Background technique [0002] With the increasing popularity of mobile communication, mobile voice communication alone can no longer meet the needs of people to obtain information. Mobile data communication services have shown great vitality and development because they can provide office, entertainment, and communication with others across geographical boundaries. prospect. It is estimated that the number of mobile users in my country will reach about 350 million by 2005, and mobile data services will develop rapidly, which is the key to new growth points and vigorous vitality of mobile communications. Code Division Multiple Access 2000 1x (Code Division Multiple Access 2000 1x, referred to as "CDMA 2000 1x"), one of the third generation (3G) mobile communication technol...
