METHOD OF TRIGGERING A LBT RANDOM BACKOFF MECHANISM IN LTE LAA |
摘要 |
The present invention provides a method of triggering a LBT random backoff mechanism in LTE LAA, the method comprising: evaluating a current channel to obtain a first parameter characterizing a congestion state of the current channel; comparing the first parameter with a first threshold to obtain a first comparison result; and adapting a contention window size based on the first comparison result. The method further comprises comparing the first parameter with a second threshold to obtain a second comparison result; and adapting the contention window size based on the second comparison result. The first parameter is a packet error rate metric or a collision metric. The method inventively uses the comparison between a first parameter characterizing a congestion state of the current channel and a predefined threshold to increase or decrease the contention window size correspondingly, such that not only the fairness problem with other Systems, a WiFi System, for example, is guaranteed, the usage efficiency of the communication resource and the performance of the whole wireless communication System will be also enhanced. |
