TERMINAL AND COMMUNICATING METHOD THEREOF IN DEVICE TO DEVICE COMMUNICATON |
| 摘要 |
A second terminal which performs direct communication with a first terminal receives a signal for measuring a radio channel from the first terminal and calculates radio channel quality. Further, the second terminal calculates a data error rate using replay information indicating whether data are received and compensates for the radio channel quality depending on a data error rate. The second terminal reports the compensated radio channel quality to a base station and the base station uses the compensated radio channel quality to allocate resources used in direct communication. |

1. A communication method of a second terminal which performs direct communication with a first terminal, comprising:
receiving a first signal for measuring a radio channel from the first terminal; calculating radio channel quality using the first signal; transmitting reply information indicating whether data are received from the second terminal to the first terminal through the direct communication; calculating an error rate of the data using the reply information; compensating for the calculated radio channel quality depending on the error rate; and reporting the compensated radio channel quality to a base station. |
