Title: Communication method, base station, and mobile terminal
Inventor: MOCHIZUKI MITSURU
IPC: H04W72/12
Filed: 2008-03-25
Abstract: Mobile terminals each monitor a candidate set of L1/L2 control information, but if the candidate set is signaled from a base station to all of the mobile terminals, the load becomes heavy in terms of wireless resources. Moreover, the processing amounts of blind detections of the mobile terminals become increased. In view of the above problems, the base station executes, based on attribute information of the mobile terminals, both a process of grouping the mobile terminals that are designations of the L1/L2 control signal and a process of allocating the L1/L2 control signal to be transmitted to the predetermined mobile terminals to the control channel elements included in the groups to which the predetermined mobile terminals belong, thereby transmitting the L1/L2 control signal by use of the downstream physical control channel. Each mobile terminal receives the downstream physical control channel; performs a blind detection process of the candidate set corresponding to the group to which the mobile terminal belongs; and executes a process of reading the L1/L2 control signal from the control channel element included in the candidate set.
