Method and apparatus for synchronizing quiet period in cognitive radio system |
摘要 |
A method and apparatus for synchronizing a Quiet Period (QP) in a Cognitive Radio (CR) system includes receiving QP information based on a channel N from at least one neighbor BS. The method further includes determining whether the channel N is an in-band channel. If the channel N is the in-band channel, QP scheduling is performed according to the received QP information based on the channel N. |

1. A method of synchronizing a Quiet Period (QP) in a Cognitive Radio (CR) system, the method comprising:
receiving, by a Base Station (BS), QP synchronization information on a channel N from at least one neighbor BS; decoding the QP synchronization information; determining whether the channel N is an in-band channel using the QP synchronization information; if the channel N is the in-band channel, determining whether the BS is currently synchronized based on another QP synchronization information on a channel M and the synchronized another QP synchronization information is broadcasted, or determining whether the QP synchronization information is received from a plurality of neighbor BSs; and if the BS is not currently synchronized based on another QP synchronization information on a channel M and the synchronized another QP synchronization information is not broadcasted, or the QP synchronization information is not received from a plurality of neighbor BSs, synchronizing a QP of the channel N, based on the QP synchronization information. |
