Abstract:
1. A method of arbitrating between wireless communications of different radio access technologies, comprising: determining, by a wireless device, a frame offset between communications of a first radio modem of the wireless device and communications of a second radio modem of the wireless device, the communications of the first radio modem asynchronous with the communications of the second radio modem; determining, by the wireless device, a plurality of potential time slot configurations that may be used for an interval of the communications of the second radio modem, each of the plurality of potential time slot configurations comprising a receive time slot, a transmit time slot, and at least one time slot that is not used or whose usage is denied in accordance with polling rules, a sequence of time slots in each of the potential time slot configurations being equivalent but different relative to other potential time slot configurations of the plurality of potential time slot configurations; determining, by the wireless device, for each of a plurality of the intervals of the communications of the second radio modem and for each potential time slot configuration of the plurality of potential time slot configurations that may be used for a respective interval, selecting, by the wireless device, a time slot configuration from the plurality of potential time slot configurations that would result in less degradation to communications of the first radio modem than other potential time slot configurations, based on the number of receive time slots and the number of transmit time slots that would be degraded; and controlling communications of the second radio modem using the time slot configuration until a change in an overall timing offset between the communications of the first radio modem and the communications of the second radio modem changes the frame offset, reducing degradation of the communications of the first radio modem due to conflicting time slots between communications of the first radio modem and the second radio modem.
