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

Abstract

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.

Problems solved by technology

[0008] In addition to imperfect TX filter and RF design, imperfect RX filter and RF design can also cause unacceptable in-device coexistence interference

For example, due to incompletely filtered transmit power from another device's transceiver, multiple RF components may become saturated, resulting in low noise amplifier (Low Noise Amplifier, hereinafter referred to as LNA) saturation and analog-to-digital conversion The Analog to Digital Converter (hereinafter referred to as ADC) does not work properly
