Enhancement of in-device coexistence interference avoidance

摘要

A method, system and device are provided for avoiding in-device coexistence interference between different radio technologies deployed in adjacent bands on the same device by reporting uplink buffer status information to the radio network and configuring LTE and non-LTE components to provide an in-device coexistence operation mode where non-LTE components use radio resources during the non-LTE on-intervals and during off-intervals inserted into the LTE on-intervals in response to predetermined trigger events.

主权项

1. A method for use in user equipment (UE) comprising first and second radio technology components, comprising:
sending, to a network component, a message to request a coexistence mode for the first and second radio technology components, the message comprising a buffer status report which indicates one or more parameters related to one or more uplink buffers at the UE, the one or more parameters indicates, to the network component, existing inference between the first and second radio technology components, and the coexistence mode allocates radio resources that reduce the existing inference between the first and second radio technology components; receiving, from the network component, a response message identifying a time division multiplexing (TDM) pattern for the first radio technology component for establishing the coexistence mode, wherein the TDM pattern for the first radio technology component is based at least in part on the buffer status report and includes on-intervals and off-intervals for the first radio technology component; and enabling the first and second radio technology components with the one or more control parameters to use radio resources on the UE wherein resources are allocated to the first and second radio technology components based at least in part on the buffer status report.
