Abstract:
1. A method of improving wireless communications between a wireless communication device and both a first communication network and a second communication network, the method comprising: providing the wireless communication device with a primary transceiver and a secondary receiver that are configured to conduct wireless communications in both a simultaneous-mode and a hybrid-mode, wherein in the simultaneous-mode the wireless communication device is configured to communicate with the second network via both the primary transceiver and the secondary receiver during a first time slot, wherein in the simultaneous-mode the wireless communication device is further configured to communicate with the second network via the primary transceiver and with the first network via the secondary receiver during a second time slot that is different than the first time slot, and wherein in the hybrid-mode the wireless communication device is configured to communicate via the primary transceiver with only one of the first network and the second network at any given time; performing simultaneous-mode-to-hybrid-mode and hybrid-mode-to-simultaneous-mode transitions based on a performance metric; and evaluating the performance metric to determine whether to perform the mode transitions, wherein a first performance metric comprises a first threshold level at which the hybrid-mode-to-simultaneous-mode transition is performed, wherein a second performance metric comprises a second threshold level at which the simultaneous-mode-to-hybrid-mode transition is performed, and wherein the first threshold level is different than the second threshold level, wherein the performance metric is a total received power (I wherein a ping-pong effect is prevented by setting the difference between the first threshold level and the second threshold level to be greater than the difference between a primary antenna gain of the primary transceiver and a secondary antenna gain of the secondary receiver.
