Abstract
Methods and structures are disclosed which facilitate co-existence of Long Term Evolution (LTE) type communication signal reception and transmission using one carrier, such as a licensed carrier, and another carrier, such as an unlicensed carrier, in the presence of other transmissions using the other carrier.
Claims26
A method for a wireless communication device to perform wireless transmissions of a first technology on a first carrier and a second technology on a second carrier, said method comprising:
- determining, by the wireless communication device, a need to perform a clear channel assessment (CCA) on the second carrier;
- coordinating, by the wireless communication device, a wireless transmission on the first carrier with performance of the CCA on the second carrier, wherein the coordinating comprises controlling, by the wireless communication device, coexistence interference by the wireless transmission on the first carrier to be below a threshold during at least a time period corresponding to the performance of the CCA on the second carrier;
- and
- commencing, by the wireless communication device, a wireless transmission on the second carrier if the CCA on the second carrier is successful.
A wireless communication device (WCD) configured to perform wireless transmissions of a first technology on a first carrier and a second technology on a second carrier, said WCD comprising:
- a transceiver;
- a processor coupled to the transceiver;
- wherein the WCD is operable to:
- perform a clear channel assessment (CCA) on the first carrier;
- commence a wireless transmission on the first carrier if the CCA on the first carrier is successful;
- determine a need to perform a CCA on the second carrier;
- coordinate wireless transmission on the first carrier with performance of the CCA on the second carrier, wherein the coordinating comprises controlling, by the WCD, coexistence interference by the wireless transmission on the first carrier to be below a threshold during at least a time period corresponding to the performance of the CCA on the second carrier;
- and
- commence a wireless transmission on the second carrier if the CCA on the second carrier is successful.
