METHOD AND DEVICE FOR REALIZING DOWNLINK CARRIER CONTROL REGION

摘要

A method for realizing a downlink carrier control region, comprises the following steps: dividing time-frequency resources on at least one carrier in a subframe into a control region and a non-control region (501), and setting the time-frequency resources of the control region by signaling (502). Correspondingly, the present invention also provides a device for realizing downlink carrier control region, which includes: a division module, used for dividing time-frequency resources on at least one carrier in a subframe into a control region and a non-control region; and a time-frequency resource setting module, used for setting the time-frequency resources of the control region by signaling. The method and device for realizing downlink carrier control region, which are provided for LTE-Advanced by the present invention, can flexibly adjust the bandwidth and frequency position of the carrier control region, realize transmitting the pilot frequency and the Physical Downlink Shared Channel PDSCH, which locate in different positions, with different power, and better realize the interference collaboration and frequency multiplexing between the cells.
