    摘要: A method and system for link adaptation between a wireless multi-carrier access point (102) and a wireless multi-carrier communication device (104) is described. The wireless multi-carrier access point obtains a set of available LEP methods from the wireless multi-carrier communication device. The wireless multi-carrier access point selects an LEP method from the set of available LEP methods, based on at least one link parameter. The wireless multi-carrier access point then communicates the LEP method selected, to the wireless multi-carrier communication device. The selected LEP method is used during the transmission of information between the wireless multi-carrier access point and the wireless multi-carrier communication device.
