APPARATUS AND METHOD FOR BROADBAND WIRELESS LOCAL AREA COMMUNICATION
First Claim
1. A method for wireless communication performed by a source node, the method comprising:
- determining a first time interval and a second time interval for a cooperated data frame transfer based on a packet transmission time at each transmission from a source node to a destination node;
transmitting a frame to a relay node through an antenna pattern directed towards the relay node at a start point of the first time interval; and
transmitting the frame to the destination node through an antenna pattern directed towards the destination node after a predetermined period of time (Ptime) from a start point of the second time interval,wherein the second time interval is allocated after the first time interval, andwherein the relay node transmits the frame to destination node after the predetermined period of time (Ptime) from the start point of the second time interval,

20. A method for wireless communication performed by a destination node, the method comprising:
-
receiving a frame from a relay node and a source node in a second time interval after a first time interval; transmitting an acknowledgment (ACK) frame indicating a reception of the frame after SIFS (Short Inter-Frame Space) within the second time interval to the source node, wherein the second time interval is allocated after the first time interval, and wherein the source node transmits the frame to the relay node in the first time internal from a start point of the first time interval, wherein the destination node receives the frame from the relay node and source node after the predetermined period of time (Ptime) from a start point of the second time interval.
