The sub channelization which accompanies power boost

摘要

Solutions Manner and the system for power boost are offered vis-a-vis the communication link or the user device between base station and the user device in mobile telecommunication network. With one execution configuration, as for communication link through the down link channel which possesses all the channel bands which include many subcarrier frequency it is down link between base station and the user device which are configurated. Whether or not as for base station vis-a-vis the down link to the user device power boost necessity it decides. When it is necessary, the signal power extending to the subcarrier frequency of all the channel bands vis-a-vis the down link to the user device the subset of subcarrier frequency from all the channel bands, as the narrow band channel or subchannel, without spreading, in order to concentrate on the subcarrier frequency of narrow channel band, you use base station. As a result, power boost is offered vis-a-vis down link. Choice figure Drawing 4
