Embodiment Construction

[0021] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] join figure 1 In the structure diagram shown, for a MU-MIMO OFDM system, K user data, that is, user data 1 to user data K, are processed by MU-MIMO, and then exchange data between the base station and each user data.

[0023] In the data processing process, the base station needs to determine the quality of the channel established with each user equipment, so as to select different transmission modes, and reasonably schedule resource blocks to transmit data to each user equipment. Combine below figure 2 For the detailed flow chart of the shown embodiment one, see figure 2 ,include:

[0024] S11: The base station determines a user equipment suitable for a multi-user MU scheduling mode fro...

Abstract

The present invention discloses a multiple-input multiple-output resource scheduling method and a base station. The method of the present invention includes: the base station determines user equipment suitable for a multi-user MU scheduling mode from multiple user equipment; the base station determines from the suitable MU scheduling mode Among the user equipments in the mode, the user equipments whose channel characteristics are closest to orthogonality are determined; between the base station and the user equipments whose channel characteristics are closest to orthogonality, use resource blocks to be scheduled to transmit data. After selecting the user equipment suitable for transmission in the MU user mode, the base station uses a resource block to transmit data between the user equipment whose channel characteristics are closest to orthogonal. In this way, reasonable scheduling of resource blocks is realized. Resource blocks can use various wireless parameters, such as bandwidth, symbol, frequency point, time slot, subband, subcarrier, PRU, etc., which improves resource utilization.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a multiple-input multiple-output resource scheduling method and a base station. Background technique [0002] Multiple input, multiple output (MIMO, multiple input multiple output) technology is a major breakthrough in smart antenna technology in the field of wireless mobile communications. This technology can double the capacity and spectrum utilization of the communication system without increasing the bandwidth; it can use multipath reception to reduce multipath fading; it can effectively eliminate co-channel interference, improve channel reliability, and reduce Bit error rate is a key technology that must be adopted in the new generation mobile communication system. [0003] At present, in the mature or nearly mature 3G / B3G wireless communication system, the base station side and the terminal side are widely adopted by configuring multiple groups of transmitting / receiving ...
