Method for allocating multiple radio communication periods
A method for allocating multiple radio communication periods to an MS supporting co-existence mode is disclosed. The method includes transmitting a co-existence mode request message to a BS by the MS, receiving information about the position of a start frame for the co-existence mode by a co-existence mode response message as a response to the co-existence mode request message from the BS by the MS, and receiving information about an allocated Wi-Fi beacon reception period by an unsolicited co-existence mode response message in the start frame from the BS by the MS. A frame allocation pattern for allocating periods for communications with a Bluetooth or Wi-Fi system using a frequency band adjacent to that of an IEEE 802.16m system can be provided according to an IEEE 802.16m frame structure, and an MS with multiple radio interfaces can communicate with each system reliably, while minimizing interference between systems.
1. A method for allocating multiple radio communication periods to a Mobile Station (MS) supporting co-existence mode, the method comprising:
transmitting a co-existence mode request message to a Base Station (BS) by the MS;
receiving information about the position of a start frame for the co-existence mode through a co-existence mode response message as a response to the co-existence mode request message from the BS by the MS; and
receiving information about an allocated Wireless Fidelity (Wi-Fi) beacon reception period through an unsolicited co-existence mode response message in the start frame from the BS by the MS.
2. The method according to claim 1 , wherein the co-existence mode request message includes a Target Beacon Transmission Time (TBTT) for the MS.
3. The method according to claim 2 , wherein the information about an allocated Wi-Fi beacon reception period is information calculated using the TBTT by the BS.
4. The method according to claim 1 , wherein the information about an allocated Wi-Fi beacon reception period includes a bitmap indicating positions of subframes in which the MS will receive a Wi-FI beacon.
5. A method for allocating multiple radio communication periods to a Mobile Station (MS) supporting co-existence mode, the method comprising:
transmitting a co-existence mode request message to a Base Station (BS) by the MS;
receiving information about the position of a start frame for the co-existence mode through a co-existence mode response message as a response to the co-existence mode request message from the BS by the MS;
requesting allocation of a Wireless Fidelity (Wi-Fi) beacon reception period to the BS through co-existence polling by the MS; and
receiving information about an allocated Wi-Fi beacon reception period through an unsolicited co-existence mode response message as a response to the co-existence polling from the BS by the MS.
6. The method according to claim 5 , wherein the co-existence mode request message includes a Target Beacon Transmission Time (TBTT) for the MS.
7. A method for allocating multiple radio communication periods to a Mobile Station (MS) supporting co-existence mode, the method comprising:
transmitting a co-existence mode request message to a Base Station (BS) by the MS;
receiving information about the position of a start frame for the co-existence mode through a co-existence mode response message as a response to the co-existence mode request message from the BS by the MS;
requesting allocation of a Wireless Fidelity (Wi-Fi) data period to the BS through co-existence polling by the MS; and
receiving information about an allocated Wi-Fi data period through an unsolicited co-existence mode response message as a response for the co-existence polling from the BS by the MS.
8. The method according to claim 7 , wherein the requesting of allocation of a Wi-Fi data period comprises requesting change of an allocated Wi-Fi data period.
9. The method according to claim 7 , further comprising transmitting a co-existence mode termination message to the BS by the MS, if the MS completes data transmission and reception in the allocated Wi-Fi data period.
10. The method according to claim 7 , wherein the information about an allocated Wi-Fi data period includes a bitmap indicating positions of subframes in which the MS will receive Wi-Fi data.
11. The method according to claim 7 , wherein the allocated WI-Fi data period includes a time period in which the MS will receive an ACKnowledgment (ACK) message for data transmitted by the MS.
