Abstract
An operation method of a device in a communication system includes receiving from a reference node a beacon including configuration information of a downlink/uplink (DL/UL) slot in a super frame #n; confirming a position of the DL/UL slot configured in the super frame #n based on the configuration information; and performing at least one of a DL reception operation and a UL transmission operation in the DL/UL slot. Also, UL communication and DL communication are allowed in the DL/UL slot, and n is an integer equal to or greater than 0.
Claims20
An operation method of a device in a communication system, the operation method comprising:
- receiving from a reference node a beacon including configuration information of a downlink/uplink (DL/UL) slot in a super frame #n;
- confirming a position of the DL/UL slot configured in the super frame #n based on the configuration information;
- and
- performing at least one of a DL reception operation and a UL transmission operation in the DL/UL slot,
- wherein UL communication and DL communication are allowed in the DL/UL slot, and n is an integer equal to or greater than 0.
An operation method of a reference node in a communication system, the operation method comprising:
- generating a beacon including configuration information of a downlink/uplink (DL/UL) slot;
- transmitting the beacon in a beacon period in a super frame #n;
- and
- performing at least one of a DL transmission operation and a UL reception operation in the DL/UL slot indicated by the configuration information in the super frame #n,
- wherein UL communication and DL communication are allowed in the DL/UL slot, and n is an integer equal to or greater than 0.
A device in a communication system, the device comprising a processor and a memory storing at least one instruction executed by the processor, wherein the at least one instruction is configured to:
- receive from a reference node a control signal indicating a frequency band #k in which a beacon #1 is transmitted, in a frequency band #m of a super frame #n;
- predict a frequency band #p in which a beacon #2 is to be transmitted in a super frame #(n+1) based on the frequency band #k and a predetermined frequency hopping pattern;
- receive from the reference node the beacon #2 including configuration information of a downlink/uplink (DL/UL) slot in the frequency band #p of the super frame #(n+1);
- identify a position of the DL/UL slot configured in the super frame #(n+1) based on the configuration information;
- and
- perform at least one of a DL reception operation and a UL transmission operation in the DL/UL slot,
- wherein UL communication and DL communication are allowed in the DL/UL slot, n is an integer equal to or greater than 0, and m and p are positive integers different from each other.
