    摘要： Embodiments of the present disclosure relate to a method and a transmitter of implementing multiple-carrier Listen-Before-Talk in a wireless communication system. The method comprises: selecting a carrier group from a plurality of carriers as a synchronization carrier; determining a transmission synchronization boundary based on an extended CCA performed on the synchronization carrier; performing an initial CCA for the plurality of carriers; and determining that transmission is to be performed on at least one of the plurality of carriers based on at least one of the result of the extended CCA and the result of the initial CCA. The embodiments according to the present disclosure require only performing eCCA on the carrier group selected as the synchronization carrier. Compared with Wi-Fi, the LTE system can compete with Wi-Fi more fairly, and compared with the traditional solution it is more possible to obtain some carriers in the unlicensed spectrum. Additionally, the channel resource usage efficiency on the unlicensed spectrum is enhanced significantly.

    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.

    摘要： The present application relates to an ESPAR antenna including a ground plane; a drive unit, located on the ground plane and oriented outward from the ground plane; and a parasitic element, located around the drive unit, comprising a control circuit configured to control electrical length between the parasitic element and the ground plane. The application further provides a method for configuring an antenna including scanning beams of the antenna in various possible operating states; comparing results of the scanning with predetermined radiation performance criteria and selecting one of the scanning results which most satisfies the predetermined radiation performance criteria; configuring the antenna based on the selected scanning result; and measuring radiation performance of the antenna, and repeating the foregoing operations when the radiation performance measured is below the predetermined radiation performance criteria.
