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.
