Title:
METHOD FOR TRANSMITTING THE PDCCH SIGNAL
Document Type and Number:
WIPO Patent Application WO/2009/155764
Kind Code:
A1
Abstract:
A method for transmitting the PDCCH (physical downlink control channel) signal is provided in the present invention. Wherein when the number of the downlink bandwidths usable resource blocks in a wireless frame is less than or equal to k, 2 symbols are fixedly used to transmit the physical downlink control channel signal, wherein the k is a natural number. Another method for transmitting the PDCCH signal is further provided. In the Long Term Evolution system with TDD mode, when the number of the downlink band usable resource blocks in a wireless frame is less than or equal to k, and the uplink/downlink switching period is 10ms, the transmitting end chooses 2, 3 or 4 symbols to transmit the PDCCH signal in the sub-frame 6, wherein the k is a natural number. With the transmission method of the PDCCH signal, the problems of the resources waste in the special scene and the descent of the transmission capability of the PDCCH can be settled, and the usage ratio of the system resources and the transmission capability of the PDCCH can be improved.
