Abstract

A method of operating a first terminal is provided. The method includes detecting a signal pattern according to motion of the first terminal by a sensor included in the first terminal, wherein the signal pattern corresponds to a pattern of wireless channel quality between the first terminal and a second terminal; predicting the wireless channel quality between the first terminal and the second terminal using the signal pattern detected by the sensor; and allocating a resource for transmitting data to the second terminal on the basis of the predicted channel quality.

First claim

What is claimed is:

1. A method of operating a first terminal, the method comprising:
detecting motion of the first terminal by a sensor terminal;
predicting a channel quality between the first terminal and a second terminal using the detected motion;
determining an interval in which the predicted channel quality is greater than or equal to a threshold value as a transmission interval and determining an interval in which the predicted channel quality is less than the threshold value as a non-transmission interval; and
allocating a resource for transmitting data to the second terminal according to the transmission interval.

2. The method of claim 1 , wherein the channel quality is an intensity of a reception signal from the second terminal.

3. The method of claim 1 , further comprising, when the non-transmission interval is greater than a predetermined time period, transmitting data at a corresponding time point of the non-transmission interval.

4. The method of claim 1 , wherein allocating the resource comprises controlling electrical transmission power for transmitting the data based on of the predicted channel quality.

5. The method of claim 1 , wherein predicting the channel quality between the first terminal and the second terminal comprises:
synchronizing a change in the channel quality between the first terminal and the second terminal with the detected motion; and
predicting the channel quality between the first terminal and the second terminal based on the basis of the change in the channel quality synchronized with the detected motion.

6. The method of claim 1 , further comprising estimating the channel quality between the first terminal and the second terminal.

7. The method of claim 6 , further comprising compensating for the estimated channel quality using the predicted channel quality.

8. The method of claim 1 , further comprising:
transmitting a reference signal to the second terminal; and
feeding back channel quality information corresponding to the reference signal from the second terminal,
wherein the channel quality information is used for predicting the channel quality between the first terminal and the second terminal.

9. The method of claim 1 , wherein the first terminal is in contact with a body of a user, and the second terminal is located within a predetermined distance from the first terminal.

10. A first terminal, comprising:
at least one sensor configured to detect motion of the first terminal;
a channel quality prediction module configured to predict a channel quality between the first terminal and a second terminal using the detected motion, and determine an interval in which the predicted channel quality is greater than or equal to a threshold value as a transmission interval, and determine an interval in which the predicted channel quality is less than the threshold value as a non-transmission interval; and
a transceiver configured to allocate a resource for transmitting data to the second terminal according to the transmission interval.

11. The first terminal of claim 10 , wherein the channel quality is an intensity of a reception signal from the second terminal.

12. The first terminal of claim 10 , wherein the transceiver is further configured to transmit data at a corresponding time point of the non-transmission interval when the non-transmission interval is greater than a predetermined time period.

13. The first terminal of claim 10 , wherein the transceiver is further configured to control electrical transmission power for transmitting the data based on the predicted channel quality.

14. The first terminal of claim 10 , wherein the channel quality prediction module is further configured to synchronize a change in the channel quality between the first terminal and the second terminal with the detected motion, and predict the channel quality between the first terminal and the second terminal based on the change in the channel quality synchronized with the detected motion.

15. The first terminal of claim 10 , wherein the transceiver comprises a channel estimation module configured to estimate the channel quality between the first terminal and the second terminal.

16. The first terminal of claim 15 , wherein the transceiver is further configured to compensate for the estimated channel quality using the predicted channel quality.

17. The first terminal of claim 10 , wherein the transceiver is further configured to transmit a reference signal to the second terminal, and feedback channel quality information corresponding to the reference signal from the second terminal, wherein the channel quality information is used for predicting the channel quality between the first terminal and the second terminal.

18. A first chip set, comprising:
a sensor module configured to detect motion of the first chip set;
a channel quality prediction module configured to predict a channel quality between the first chip set and a second chip set using the detected motion, and determine an interval in which the predicted channel quality is greater than or equal to a threshold value as a transmission interval and determine an interval in which the predicted channel quality is less than the threshold value as a non-transmission interval; and
