Claim of US Patent No. 9,301,148

1. A method for maintaining redundancy of a wireless communication network, comprising:
partitioning a frequency band that is used by both a first base station transceiver subsystem and a second base station transceiver
subsystem into a plurality of resource blocks;

partitioning each of the partitioned resource blocks into a first frequency partition and a second frequency partition which
are configured to have a same structure as each other; and

transmitting and receiving,
by the first base station transceiver subsystem, first data using a first resource block allocated to the first frequency
partition, and

by the second base station transceiver subsystem, second data using a second resource block allocated to the second frequency
partition,

wherein a first coverage formed by the first base station transceiver subsystem and a second coverage formed by the second
base station transceiver subsystem have a substantially same cell coverage and a same cell identification (ID), to thereby
provide a redundant cell coverage.
