摘要： A base station receives channel state information corresponding to each of spare coordinated groups from each of user devices. A first group includes a plurality of coordinated groups arranged in advance. The spare coordinated groups corresponding to each user device are such as selected from the first group and include at least a service sector of best channel quality obtained measurement by the user device. The base station specifies a user device group corresponding to each of coordinated groups contained in each of coordinated group patterns. The user device group corresponding to the coordinated group is formed of user devices having the coordinated group in their spare coordinated groups. The base station uses channel state information reported from the user devices of the user device group corresponding to the coordinated group as a basis to perform user scheduling on the coordinated group.

摘要： The present invention provides a method for resource allocation, a base station and a mobile communication terminal. The method includes: setting a persistent radio resource set and a complementary resource set pre-allocated to a terminal; determining a radio resource to be used according to the size of a packet to be transmitted by the terminal or the base station. According to one embodiment of the present invention, when a whole packet cannot be transmitted by using the pre-allocated persistent resource, the complementary resource can be allocated to the terminal so that the packet doesn't need to be divided, time delay is reduced, physical layer control information is decreased and the number of accommodated terminal users is increased. The present invention is applicable to any service in which packets arrive periodically, such as VoIP service and real-time service.
