Embodiment 1

[0028] figure 1 It is a flowchart of a method for avoiding device coexistence interference in Embodiment 1 of the present invention. In this embodiment, when the eNB learns that the coexistence communication module of the terminal is turned on, if the auxiliary information sent by the terminal is not obtained, the eNB adopts the initial TDM mode to set the connection between the LTE / LTE-A communication module and the coexistence communication module of the terminal. way of working. After the terminal has measured for a period of time and notified the eNB of relevant auxiliary information, the eNB then determines the working mode between the LTE / LTE-A communication module and the coexistence communication module of the terminal according to the auxiliary information, and notifies the terminal. Specifically, the method includes the steps of:

[0029] In step S110, the terminal sends a notification message of starting the coexistence communication module to the eNB, so as to no...

Embodiment 2

[0054] In the first embodiment above, the eNB provides initial TDM setting information for the terminal. In Embodiment 2, in order to simplify the system design, the above step S120 can be omitted, and before providing the auxiliary information to the eNB, the terminal itself decides to adopt the initial TDM setting and notifies the terminal.

[0055] Such as figure 2 As shown, the flow of the method for avoiding device coexistence interference in Embodiment 2 includes the following steps:

[0056] In step S210, the terminal sends a notification message of starting the coexistence communication module to the eNB, so as to notify the eNB of starting the coexistence communication module.

[0057] Preferably, this step can be triggered when one of the following situations occurs: a) the coexistence communication module of the terminal has just been started, such as the coexistence communication module has just been powered on; b) the coexistence communication module of the term...

Embodiment 3

[0067] In the above two embodiments, when the terminal has just completed the network handover and the coexistence communication module has been started, the terminal sends the coexistence communication module activation notification message to the eNB. In this embodiment, the source eNB of the terminal may send the coexistence communication module activation notification message to the target eNB of the terminal during the network handover process and after the network handover is completed.

[0068] like image 3 As shown, the flow of the method for avoiding device coexistence interference in this embodiment includes the following steps:

[0069] Step S310, during or after the network handover, if the coexistence communication module of the terminal has been activated, the source eNB sends a coexistence communication module activation notification message to the target eNB.

[0070] Optionally, after receiving the notification message from the source eNB, the target eNB may...

Abstract

The present invention provides a method, a terminal and a base station for avoiding equipment coexistence interference of a wireless communication terminal. The wireless communication terminal includes an LTE / LTE-A communication module and a coexistence communication module. The method includes the following steps: a first sending step, sending a message to the base station. sending a coexistence communication module start notification message; and a first interference avoidance step, before sending the auxiliary information to the base station, the wireless communication terminal uses time division multiplexing between the LTE / LTE-A communication module and the coexistence communication module TDM mode.

Description

technical field [0001] The present invention relates to wireless communication technology, and more specifically relates to a method, terminal and base station for avoiding equipment coexistence interference of wireless communication terminals. Background technique [0002] In recent years, the rapid growth of various wireless applications has led to the rapid development of wireless communication systems. On the one hand, the performance of various wireless communication technologies (such as third-generation and fourth-generation cellular networks, wireless local area networks, Bluetooth, etc.) has been greatly improved; After the emergence of smart terminals, user terminals can integrate communication modules of various wireless systems (this paper refers to the coexistence of multiple communication modules as device coexistence), and then can access multiple wireless networks at the same time, such as long-term evolution (LTE) LongTermEvolution (LTE) system and enhanced...
