Method and apparatus for service continuity across LF and mmWave
A data packet, that is to be transmitted in a dual connectivity (DC) or carrier aggregation (CA) based communications system, may include an indication to indicate whether the data packet is configured to be transmitted in a first frequency of a first carrier or a second frequency of a second carrier, and be transmitted, by a communication device, in the first frequency or the second frequency based on the indication. A data packet in the communications system may also be transmitted first in a first frequency higher than a second frequency, and then be retransmitted in the second frequency upon transmission failure of the data packet in the first frequency.
