Method and system for a time domain approach to 4G/LTE-WiFi/BT coexistence

摘要

A method and system are provided in which a device that is operable to handle WiFi communication and WiMAX communication may receive downlink medium access protocol (MAP) information in a downlink sub-frame of a WiMAX frame and disable WiFi transmission during a portion of the downlink sub-frame based on the downlink MAP information. The disabled WiFi transmission may be enabled after data within the downlink sub-frame is decoded. The device may also receive uplink MAP information in the downlink sub-frame and may control a clear channel assessment associated with the WiFi transmission based on the uplink MAP information. The MAP information may comprise data or burst profile information and/or one or more physical control messages. A similar time domain approach may be utilized for coexistence between Win and long term evolution (LTE) coexistence, Bluetooth and WiMAX, and Bluetooth and LTE. Frame aggregation may be enabled to alleviate pending WiFi traffic.

主权项

1. A method comprising:
receiving downlink medium access protocol (MAP) information in a downlink sub-frame of a first wireless protocol; disabling a transmission of a second wireless protocol during a portion of the downlink sub-frame based on the received downlink MAP information; enabling the disabled transmission of the second wireless protocol upon conclusion of decoding of available data within the downlink sub-frame; receiving uplink MAP information in the downlink sub-frame of the first wireless protocol; generating a signal during an uplink sub-frame of the first wireless protocol based on the received uplink MAP information; and controlling a clear channel assessment operation associated with the transmission of the second wireless protocol based on the generated signal, wherein the receiving, disabling and enabling are performed by a communications device to thereby reduce interference between the first wireless protocol and the second wireless protocol, wherein the first wireless protocol is a fourth generation (4G) protocol and the second wireless protocol is one of WiFi and Bluetooth.
