摘要： The present disclosure provides channel sensing in an efficient manner in a cognitive radio MAC protocol and improves channel utilization. Proposed is an Adaptive Channel Sensing (ACS) for variably sensing a channel in accordance with a Fixed Channel Sensing (FCS) and a channel state so as to perform the channel sensing in an efficient manner while reducing the power consumption of a terminal. Further proposed is a self-scheduling mechanism which enables multiple terminals to simultaneously transceive data by means of a slot-based contention on the basis of the results of the FCS and ACS, which are proposed by the present disclosure.

The method includes the steps of forming an encryption tag field that includes information about an encryption tag type, which indicates whether transmission data is encryption-enabled or encryption-disabled; forming a packet data field which includes encrypted transmission data; forming a first integrity check field indicating the CRC check sum of the encrypted data; forming a length and type field indicating the sum of the lengths of the packet data field and the first integrity check field. Finally, a transmission frame is formed with these formed fields, a source address field indicating the address of the source point, and a destination address field indicating the address of the target point.

摘要： An uplink packet data transmission system and method are provided which can reduce a collision probability in a contention period by assigning a priority to mobile stations when bandwidth allocation is rejected due to lack of resources of a base station from which a best effort service is provided. In a method for transmitting best effort data in a communication system, the base station allocates resources to mobile stations for which a reservation has been made in a previous time period when bandwidth for the mobile stations requesting bandwidth allocation is insufficient, reserves bandwidth for mobile stations for which the bandwidth allocation has been rejected, and transmits reservation information. The mobile stations receive the reservation information, skip a next scheduled bandwidth allocation request, and transmit data through bandwidth allocated from the base station.
