Abstract:
1. A method of arranging a shortened resource block (RB) without a direct current (DC) subcarrier for a wireless communication system comprising a communication device and a network, the method comprising: selecting, by the communication device or the network, a RB from a plurality of RBs comprising a plurality of available subcarriers, according to a configuration, wherein the RB comprises a plurality of subcarriers; and removing, by the communication device or the network, the DC subcarrier from the plurality of subcarriers of the RB according to the configuration, to construct the shortened RB without the DC subcarrier, to solve misalignment of DC subcarriers of the communication device and a legacy communication device; wherein the configuration is determined according to a carrier frequency of the communication device; wherein a number of subcarriers of the shortened RB is less than a number of subcarriers of another RB in the plurality of RBs.
