    摘要： A base station apparatus includes a correction unit for correcting a CQI reported from a user apparatus and a scheduler for scheduling based on the corrected CQI. The correction unit uses a correction table to correct the CQI such that if the reported CQI is poor, the CQI is slightly reduced, and otherwise, the CQI is significantly reduced. One method of generating the correction table includes deriving a first SINR in consideration of the number of interference users less than (n−1) and a second SINR in consideration of the number of interference users equal to (n−1) to explore a distribution of the second SINR to the first SINR. In this method, correspondence between the first SINR and the second SINR is determined based on the distribution to generate the correction table.

    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.
