Abstract
Disclosed is a method and an apparatus for communication in a TDD (Time Division Duplex) based wireless communication system. The present invention involves setting a first frame comprising a plurality of consecutive downlink subframes and a plurality of consecutive uplink subframes. The start point for the first uplink subframe in the plurality of consecutive uplink subframes, is located at a switching point in a second frame used by another system.
Claims7
A method for communication in a time division duplex (TDD)-based wireless communication system where a first system and a second system coexist wherein the first system and the second system are different systems from each other, the method comprising:
- configuring a first frame for the first system to include at least one downlink subframe and at least one uplink subframe;
- configuring a second frame for the second system to include a plurality of virtual frames, a size of the second frame being integer n times of a size of the first frame, a size of each of the plurality of virtual frames being identical with the size of the first frame;
- and
- transmitting data by using the first frame for the first system and the second frame for the second system,
- wherein the first frame is configured to have a minimum number of punctured symbols and a frame offset with one of the plurality of virtual frames,
- wherein a start point of the first frame is aligned to a start point of one of the plurality of virtual frames, and
- wherein a number of switching points in each of the plurality of virtual frames is equal to a number of switching points in the first frame.
An apparatus configured to communicate in a time division duplex (TDD)-based wireless communication system where a first system and a second system coexist, wherein the first system and the second system are different systems from each other, the apparatus comprising:
- a frame configuration unit adapted to configure a first frame for the first system to include at least one downlink subframe and at least one uplink subframe, and a second frame for the second system to include a plurality of virtual frames, a size of the second frame being integer n times of a size of the first frame, a size of each of the plurality of virtual frames being identical with the size of the first frame,
- wherein the first frame is configured to have a minimum number of punctured symbols and a frame offset with one of the plurality of virtual frames,
- wherein a start point of the first frame is aligned to a start point of one of the plurality of virtual frames, and
- wherein a number of switching points in each of the plurality of virtual frames is equal to a number of switching points in the first frame;
- and
- a transceiver configured to transmit data by using the first frame for the first system and the second frame for the second system.
