METHOD AND APPARATUS FOR USING WIRELESS INTERFACE TECHNIQUE AND COMMUNICATION SYSTEM

摘要

Disclosed is a method for using a wireless interface technique, comprising: a base station dividing a frequency band of a cell into N frequency intervals, wherein the N frequency intervals comprise a common frequency interval and a dedicated frequency interval; the base station sends information about the N frequency intervals and random access resource information about the cell to the UE; the base station maps a service bearer DRB of the UE onto at least one frequency interval of the N frequency intervals; and transmitting a service borne by the DRB with the UE using a wireless interface technique supported by the designated frequency interval onto which the DRB is mapped. The method for using a wireless interface technique comprises: a UE which uses a common frequency interval, and optionally the UE using a dedicated frequency interval to perform wireless network access. The technical solution in the embodiments of the present invention can flexibly adjust wireless resource allocation according to different demands, thereby improving the utilization rate of radio resources.
