Method of in-device interference mitigation for cellular, bluetooth, WiFi, and satellite systems coexistence

摘要

A coexistence interference mitigation method is provided. In a wireless network, a wireless device is equipped with multiple radios in the same device platform. The wireless device also has a control entity that communicates with the multiple co-located radio modules. A first radio module receives a notification from the control entity. The notification informs a critical signaling status of a second radio module co-located with the first radio module. Upon receiving the notification, the first radio module stops uplink transmission due to coexistence interference and transmits a coexistence indicator to its serving eNB. After a certain period, the first radio module receives a second notification that informs a completion status of the critical signaling of the second radio module. Upon receiving the second notification, the first radio module resumes uplink transmission and transmits a coexistence resume indicator to the eNB.

主权项

1. A method comprising:
(a) receiving a notification from a processor by a first transceiver, wherein the processor notifies a critical signaling status of a second transceiver co-located with the first transceiver; (b) stopping an ongoing uplink transmission with a base station for a period of time by the first transceiver and ignoring uplink transmission opportunity granted to the first transceiver by the base station in response to the notification of the critical signaling status of the second transceiver; and (c) transmitting a coexistence indicator from the first transceiver to the base station to prevent the base station from sending a false alarm and from triggering additional coexistence interference mitigation functions for the first transceiver during the period of time.
