Abstract

A method of transmitting data by at least one access terminal (AT) in a wireless communication system is disclosed. More specifically, the method includes ceasing all transmissions by the at least one AT during a duration corresponding to a duration used by an access node (AN) to transmit a superframe preamble, wherein the superframe comprises a plurality of physical frames.

Claims

1. A method of transmitting data by a terminal in a wireless communication system, the method comprising:

transmitting, by the terminal, first type link control information during a first part of a first frame on a first type link of a superframe,

wherein a second part of the first frame on the first type link isa silent period during which all transmission by the terminal is ceased,

wherein the first part of the first frame on the first type link corresponds to a predefined number of orthogonal frequency division multiplexing (OFDM) symbols portion of a first frame on a second type link, and the second part of the first frame on the first type link corresponds to a remaining portion of the first frame on the second type link;

receiving, by the terminal, a second type link signal from a base station in the first frame on the second type link; and

transmitting, by the terminal, data in a second frame on the first type link of the superframe,

wherein the second type link signal carries second type link data and second type link control information for the terminal,

wherein no data is transmitted by the terminal during the first part where the control information is transmitted in the first frame on the first type link, and no data is transmitted during the second part which is the silent period in the first frame on the first type link,

wherein the first type link is directed from the terminal and the second type link is directed from the base station.

2. The method of claim 1,

wherein the superframe comprises a plurality of physical frames, and

wherein each of the plurality of physical frames comprises a plurality of OFDM symbols.

3. The method of claim 1, wherein the ceasing of the transmission occurs periodically.

4. The method of claim 3, wherein the periodic ceasing of the transmission is informed by a system parameter.

5. The method of claim 1, wherein the ceasing of the transmission occurs periodically according to a command from the base station.

6. A device configured to transmit data in a wireless communication system, the device comprising:

a transceiver configured to

transmit first type link control information during a first part of a first frame on a first type link of a superframe,

wherein a second part of the first frame on the first type link isa silent period during which all transmission by the transceiver is ceased,

wherein the first part of the first frame on the first type link corresponds to a predefined number of orthogonal frequency division multiplexing (OFDM) symbols portion of a first frame on a second type link, and the second part of the first frame on the first type link corresponds to a remaining portion of the first frame on the second type link;

receive a second type link signal from a base station in the first frame on the second type link; and

transmit data in a second frame on the first type link of the superframe,

wherein the second type link signal carries second type link data and second type link control information for the device,

wherein no data is transmitted by the transceiver during the time portion first part where the control information is transmitted in the first frame on the first type link, and no data is transmitted during the second part which is the silent period in the first frame on the first type link,

wherein the first type link is directed from the terminal and the second type link is directed from the base station.
