Abstract

The invention provides a resource scheduling method and a resource scheduling device in a multi-carrier communication system. The resource scheduling method comprises the following steps: acquiring capability information of a terminal; and configuring receiving bandwidth of the terminal to enable the baseband direct current position in the receiving bandwidth to correspond to the empty sub-carrier position in transmitting bandwidth of a base station. According to the resource scheduling method and device disclosed by the application, the situation that the DC position of the terminal is aligned with a non-empty sub-carrier is avoided and the problem of data receiving in the position of local oscillation leakage interference direct current carrier of the terminal is effectively solved.

Description

technical field

[0001] The present application relates to wireless communication technologies, and in particular, to a resource scheduling method and resource scheduling device in a multi-carrier communication system. Background technique

[0002] Currently, in the Intra-band contiguous CA (Intra-band contiguous CA) scenario defined in 3GPP, for TDD, the aggregated bandwidth on the base station side is 50MHz, and the aggregated bandwidth on the terminal side is only 40MHz due to capacity limitations. That is to say, the base station side will use 3 carriers, and the current terminal class supports up to 2 carriers. Such asymmetry between the base station and the terminal will bring about the problem that the terminal cannot normally receive the position data of its baseband DC carrier.

[0003] Since the sub-carrier at the center DC position of each carrier in a multi-carrier communication system or carrier aggregation system is empty, and the terminal adopts a zero-IF stru...
