Embodiment 1

[0021] Example 1 (TDD system)

[0022] like figure 2 As shown, the base station is configured with three carriers in the Band 40 (2300-2400MHz) frequency band, namely CC1 (20MHz), CC2 (20MHz) and CC3 (10MHz), both terminals UE1 and UE2 support Band 40, and UE1 is in this Up to two carrier receptions are supported in the frequency band, and UE2 supports up to one carrier in the frequency band.

[0023] When UE1 and UE2 report the above capability information to the network side through, for example, RRC signaling, or the network side obtains the above capability information of UE1 and UE2 from the core network, the base station can schedule UE1 to CC1 and CC2 according to the capability of UE1, so that UE1 The receiving baseband DC position is located at the center of the two carriers, which does not affect normal data reception, and UE2 can be scheduled to CC1, CC2 or CC3 according to the capability of UE2. If most of the activated terminals in the base station support at...

Embodiment 2

[0024] Embodiment 2 (FDD system)

[0025] The difference between the FDD system and the TDD system is that the transmit bandwidth of the base station in the TDD system is the same as the receive frequency, while the base station in the FDD system uses different frequencies for transmit and receive.

[0026] like image 3 As shown, the base station is configured with three carriers in the Band 7 (2500-2570 / 2620-2690MHz) frequency band, namely CC1 (20MHz), CC2 (20MHz) and CC3 (10MHz), of which the 2620-2690MHz part is the transmission bandwidth . Both terminals UE1 and UE2 support Band 7, and UE1 supports up to two carrier receptions (R10) in this frequency band, and UE2 supports up to one carrier (R8 / R9) in the frequency band.

[0027] When UE1 and UE2 report the above capability information to the network side through, for example, RRC signaling, or the network side obtains the above capability information of UE1 and UE2 from the core network, the base station can schedule...

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...
