Abstract:
1. A method for processing baseband uplink and downlink sub-frames, comprising: at a base station of a Long Term Evolution-Time Division Duplex (LTE-TDD) system, receiving, by a receiving antenna of the base station, uplink sub-frames 2, 3, 4, 7, 8, and 9; transferring, by the receiving antenna, the received uplink sub-frames to a baseband processor of the base station; processing, by the baseband processor, the uplink sub-frames transferred by the receiving antenna; processing, by the baseband processor, downlink sub-frames 0, 1, 5, and 6; transferring, by the baseband processor, the processed downlink sub-frames to a transmitting antenna; and transmitting, by the transmitting antenna, the downlink sub-frames transferred by the baseband processor, wherein the baseband processor processes the uplink sub-frames and the downlink sub-frames serially in an order of a sub-frame 2 of a current frame, a sub-frame 3 of the current frame, a sub-frame 6 of the current frame, a sub-frame 4 of the current frame, a sub-frame 0 of a next frame, a sub-frame 7 of the current frame, a sub-frame 8 of the current frame, a sub-frame 1 of the next frame, a sub-frame 9 of the current frame, and a sub-frame 5 of the next frame, wherein information solved from the uplink sub-frame 2 of the current frame is to be sent back to a downlink channel at the downlink sub-frame 6 of the current frame, information solved from the uplink sub-frames 3 and 4 of the current frame is to be sent back to the downlink channel at the downlink sub-frame 0 of the next frame, information solved from the uplink sub-frame 7 of the current frame is to be sent back to the downlink channel at the downlink sub-frame 1 of the next frame, information solved from the uplink sub-frames 8 and 9 of the current frame is to be sent back to the downlink channel at the downlink sub-frame 5 of the next frame; wherein a length of time slots for processing each sub-frame meets formulae wherein T
