Claim of US Patent No. 9,622,217

1. An uplink-downlink configuration method in a system in a Time Division Duplex (TDD) communication mode, the method comprising:
a central node device receiving a reference information, for configuring an uplink-downlink configuration, transmitted by
a network node device managed by the central node device;

the central node device configuring the uplink-downlink configuration according to the received reference information; and
the central node device transmitting information about the uplink-downlink configuration configured by the central node device
to the corresponding network node device or to a corresponding network node device and a user equipment;

wherein the reference information comprises a combination of at least one of following information and an utilization ratio
of uplink sub-frames, an utilization ratio of downlink sub-frames of the network node device, and the user equipment;

wherein the following information comprises:
an amount of data to be transmitted in the uplink and an amount of data to be transmitted in the downlink of the network node
device and/or the user equipment;

an amount of data to be transmitted in the uplink, an amount of data to be transmitted in the downlink, an amount of data
transmitted in the uplink and an amount of data transmitted in the downlink of the network node device and/or the user equipment;

a demand ratio of uplink/downlink sub-frames of the network node device and/or the user equipment; and
a reference configuration information of uplink/downlink sub-frames of the network node device and/or the user equipment.
