METHOD AND APPARATUS FOR REDUCING SELF-JAMMING OF TRANSMISSIONS ON ADJACENT CARRIERS

摘要

The present disclosure provides methods and apparatuses for multi-carrier transmissions over adjacent channels that reduce self-jamming due to asymmetric interference. In an aspect, a large bandwidth load-base equipment (LBE) carrier may be provided such that CCA is performed jointly over the entire bandwidth. In another aspect, additional CCA timeslots may be used to synchronize the two carriers. In a further aspect, an extended CCA may be performed on a primary unlicensed carrier while a simple CCA may be performed on a secondary unlicensed carrier. In yet another aspect, LBE may be deployed on some carriers while frame-base equipment (FBE) may be deployed on other carriers.

主权项

1. A method of wireless communication, comprising:
receiving data for transmission over at least two unlicensed carriers, the at least two unlicensed carriers including a first unlicensed carrier and a second unlicensed carrier; performing an extended clear channel assessment (ECCA) countdown on the first unlicensed carrier; determining a potential last timeslot from one or more potential last timeslots of the ECCA countdown on the first unlicensed carrier; and performing a clear channel assessment (CCA) check on the second unlicensed carrier during the potential last timeslot.
