Patent attributes
Systems and methods for improving Long Term Evolution (LTE)-WiFi coexistence in a network, including configuring one or more LTE nodes for asynchronous access and synchronous transmission to bridge LTE and WiFi access modes. A channel is reserved for LTE transmission in the one or more LTE nodes, and a supplementary WiFi module is provided in the one or more LTE nodes for sensing the channel for occupancy and for broadcasting a reservation signal on the channel prior to the LTE transmission. Contention window sizes are scaled linearly by increasing the contention window sizes proportionally to a subframe collision rate to maintain throughput fairness to the WiFi, and synchronous transmission from the one or more LTE nodes to one or more User Devices (UEs) is performed by activating the unlicensed carrier for a reserved time period.
