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 communicating in a wireless communication system, the method comprising:

transmitting, by a terminal to another terminal via a first link, first control information and no data during a first part of a first subframe of a frame,

wherein a second part of the first subframe of the frame is a silent period during which no transmission by the terminal occurs;

transmitting, by the terminal to the another terminal via the first link, first data in a second subframe of the frame; and

receiving, by the terminal from a base station via a second link, second data or second control information in the first subframe of the frame,

wherein the first part of the first subframe of the first link corresponds to a predefined number of orthogonal frequency division multiplexing (OFDM) symbols of the first subframe of the second link, and the second part of the first subframe of the first link corresponds to a remaining number of OFDM symbols of the first subframe of the second link.

2. The method of claim 1, wherein the silent period is a periodic silent period.

3. The method of claim 1, wherein the silent period is informed by a system parameter.

4. The method of claim 1, wherein the silent period occurs periodically according to a command from the base station.

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

a transceiver configured to

transmit, to another terminal via a first link, first control information and no data during a first part of a first subframe of a frame,

wherein a second part of the first subframe of the frame is a silent period during which no transmission by the terminal occurs;

transmit, to the another terminal via the first link, first data in a second subframe of the frame; and

receive, from a base station via a second link, second data or second control information in the first subframe of the frame,

wherein the first part of the first subframe of the first link corresponds to a predefined number of orthogonal frequency division multiplexing (OFDM) symbols of the first subframe of the second link, and the second part of the first subframe of the first link corresponds to a remaining number of OFDM symbols of the first subframe of the second link.

6. The device of claim 5, wherein the silent period is a periodic silent period.

7. The device of claim 5, wherein the silent period is informed by a system parameter.

8. The device of claim 5, wherein the silent period occurs periodically according to a command from the base station.
