Method for broadcasting system information wireless packed data transmission

Abstract

The base station broadcasts the system information within the subzone range. Besides the general information of the system information block, the system information includes following information: the available code resources in the downward shared channel used by the adjacent subzone to transmit packet data; the power bias between the public pilot channel and the downward shared channel in the adjacent subzone. The method reduces the possibility that the mobile station soon switches to another subzone from the subzone just switching in since too high load and the poor channel quality. Moreover, the mobile station can use these system informations, combining own measured value to choose best subzone, in order not to waste the system resources.

Description

Technical field [0001] The present invention relates to a broadband code division multiple access mobile communication system, and more specifically to a method for broadcasting system information in wireless packet data transmission. Background technique [0002] In the wireless packet data transmission system, the mobile station needs to know the relevant system information for initial access and cell selection. In addition to the system information block information defined in the wideband code division multiple access version 99, the wireless data system The cell selection in the cell selection also needs to know the available code resources in the downlink shared channel used by the neighboring cell to transmit packet data and the power offset between the common pilot channel and the downlink shared channel in the neighboring cell to determine whether the target serving cell Meet the requirements of handover. [0003] Currently, the commonly used broadcast method is to notif...
