Permitting coexistence of data transfer of interferring wireless signals

摘要

A system and method of permitting coexistence of WiFi and Bluetooth® data transfer on a single chip in UE including a transceiver includes using CTS data packets to protect Bluetooth® signals for SCO communication links; using only WiFi circuitry in the chip to determine when Bluetooth® data transfer is required by the UE; establishing a specified period of the Bluetooth® data transfer; and starting WiFi medium contention only upon an end of the specified period of the Bluetooth® data transfer on the single chip. The power save mode of the WiFi circuitry may be used with Bluetooth® ACL data packets in WiFi periodic data transfer gaps. The WiFi data transfer has no timing constraints, whereas the Bluetooth® data transfer has timing constraints and can only occur during the specified period. The WiFi data transfer does not occur when the Bluetooth® data transfer is occurring.

1. A method comprising:
using clear to send (CTS) data packets to protect signals of a first data transmission protocol for synchronous connection-oriented (SCO) communication links; using a circuitry of a second data transmission protocol to determine when a data transfer of the first data transmission protocol is to be implemented; establishing a period for the data transfer of the first data transmission protocol; starting a medium contention of the second data transmission protocol upon an end of the period; determining the circuitry of the second data transmission protocol has entered into a power save mode; indicating, from the circuitry for the second data transmission protocol, to a router that a transceiver is entering into the power save mode; and beginning, by the circuitry for the second data transmission protocol, asynchronous connection-less (ACL) data packet transmissions of the first data transmission protocol in periodic data transfer gaps of the second data transmission protocol during the power save mode, wherein a data transfer of the second data transmission protocol has no timing constraints, and the data transfer of the first data transmission protocol has timing constraints and occurs during the period.
