Problems solved by technology

[0008] In addition to imperfect TX filter and RF design, imperfect RX filter and RF design may also cause unacceptable in-device coexistence interference (coexistence interference)
As an example, some RF components may be saturated with transmit power from another device's transceiver, but not fully filtered, causing low-noise amplifier (LNA) saturation and analog-to-digital converter (ADC) saturation. )Not working properly
Such problems may exist regardless of the frequency separation between the TX and RX channels

Embodiment Construction

[0029] Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] image 3 In accordance with a novel aspect, a schematic diagram of a user equipment UE 31 with multiple wireless transceivers in a wireless communication system 30. The wireless communication system 30 includes a user equipment UE31, a serving base station (for example, an evolved node-B) eNB32, a WiFi access point WiFi AP33, a Bluetooth device BT34, and a global positioning system satellite device GPS35. The wireless communication system 30 provides various network access services for the UE 31 through different wireless access technologies. For example, eNB32 provides access to cellular wireless networks (for example, 3GPP Long-Term Evolution (LTE) or LTE enhanced (LTE-Advanced, LTE-A) systems), and WiFi AP33 provides wireless local area network (Wireless Local Area Network) access. , WLAN) access in the local coverage (local coverage), BT34 ...

Abstract

A wireless device having a central control entity that coordinates multiple radio transceivers co-located within the same device platform to mitigate coexistence interference. The wireless device comprises an LTE transceiver, a WiFi transceiver, a BT transceiver, or a GNSS receiver. In one embodiment, the central control entity receives radio signal information from the transceivers and determines control information. The control information is used to trigger FDM solution such that the transceivers operate in designated frequency channels to mitigate co-existence interference. In another embodiment, the central control entity receives traffic and scheduling information from the transceivers and determines control information. The control information is used to trigger TDM solution such that the transceivers are scheduled for transmitting or receiving radio signals over specific time duration to mitigate co not existence interference. In yet another embodiment, power control solution is used to mitigate coexistence interference.
