Receive (rx) rate control for thread coexistence with other radios

Abstract

An approach is described for a wireless device comprising a transceiver and a processor communicatively coupled to the transceiver. In a thread-based device, a thread radio coexists with a primary radio, such as a Bluetooth or WiFi radio. Because both radio share a common frequency band, the thread radio requests grants from the primary radio for transmission and reception. So as to avoid bogging down the primary radio, the thread radio throttles its requests. Specifically, the thread radio tracks certain variables indicative of the number of requests that have been made within a time window and the types of requests that have been made to the primary radio. By limiting the number of total requests and the number of requests of each type within the time window, the thread radio avoids overburdening the primary radio.
