TECHNOLOGY-SPECIFIC LISTEN BEFORE TALK PARAMETER ADJUSTMENTS FOR COMMON ENERGY DETECTION THRESHOLDS

Abstract:

Technology-specific listen before talk (LBT) parameter adjustments are disclosed for common energy detection (ED) thresholds. Some of the technologies sharing access to the same shared communication spectrum include additional access deferral procedures. Such technologies may be configured with additional compensating features to increase the likelihood of fairness in spectrum access across all technologies sharing a common ED threshold. Such additional compensating features may include a reduced contention window size relative to the technologies that do not include such additional access deferral procedures, increased maximum channel occupancy times (COTs) for longer transmissions, and the like. Each such additional compensating feature may be available under different circumstances, such as always available or available in response to the node activating one of the additional access deferral procedures. Additionally, such additional compensating features may, once initiated, be active and available for a predetermined period of time.
