Patent ID: 8666427

Claim:
A method for mobile communication, adapted to a mobile communication system comprising a main base station (BS) and a plurality of sub-communication devices, wherein each of the sub-communication devices is one of a sub-BS and a user equipment, and a sub coverage area of the sub-BS and a location of the user equipment are located in a main coverage area of the main BS, and the method for mobile communication comprising: obtaining sub-communication device information, wherein the sub-communication device information comprises locations of the sub-communication devices; grouping the sub-communication devices based on the locations of the sub-communication devices; obtaining an allocation of resource blocks according to a grouping result, wherein the grouping result comprises at least two groups of the sub-communication devices and the at least two groups of the sub-communication devices are allocated to different resource blocks; receiving the allocation of the resource blocks by the sub-communication devices for controlling signalling, data transmission and data reception; enabling usages of same resource blocks by the sub-communication devices allocated in the same resource blocks in response to receipt of the allocation; determining that a first user equipment is located within a sub coverage area of a first sub-BS, wherein the first user equipment and the first sub-BS are sub-communication devices located in the main coverage area of the main BS; and receiving a handover signal by the first user equipment when the first user equipment is located within the sub coverage area of the first sub-BS, so that the first user equipment transmits and receives data through the first sub-BS, wherein before the first user equipment receives the handover signal, the main BS detects and confirms whether the first user equipment is indeed located within a communication range of the first sub-BS.
