The present disclosure provides a method and system for scheduling group resources during trunking communication. The method includes: classifying base stations connected to a trunking switch center into at least one co frequency base station set and marking a base station that cannot be classified into the at least one co frequency base station set as a different frequency base station according to central frequencies and home regions of the base stations; step when a group call is established, allocating the same trunking shared channel and designating the same packet delivery time to base stations in one co frequency base station set, and notifying each base station in the co frequency base station set of the trunking shared channel and the packet delivery time; and step the base stations in the co frequency base station set starting to send trunking packets on the trunking shared channel at the packet delivery time.

Disclosed are method and apparatus for allocating radio resources. The method for allocating radio resource includes: determining, by a base station, a group of downlink sub-channels and transmission parameters related to the group of downlink sub-channels according to downlink channel characteristics and downlink interference characteristics of each resource block and a downlink bandwidth requirement of a terminal reported by the terminal, and transmitting the group of downlink sub-channels and the related transmission parameters determined to the terminal. The method and apparatus are able to allocate radio resources and determine transmission parameters based on user service requirement and system channel conditions, which greatly optimizes the system performances and improves efficiency.
