Embodiment Construction

[0027] figure 1 It is a flowchart of a method for triggering IDC interference indication in LTE in the present invention; as figure 1 As shown, the non-LTE module mentioned in the present invention is other wireless modules except the LTE module, such as Bluetooth module, infrared module, WIFI module and so on.

[0028] Step 101, the LTE module in the UE acquires the maximum number of autonomous rejections N of the LTE module MAX DL And the maximum number of autonomous rejections N of non-LTE modules MAX UL ;

[0029] Step 102, set the uplink timer T respectively UL and down timer T DL The timing cycle; initialize the up counter N UL and down counter N DL ;

[0030] Step 103, when the LTE module causes uplink interference to the non-LTE module for the first time, start the uplink timer T UL , the LTE module performs an autonomous rejection, and the uplink counter N UL Add 1; after each uplink interference, the LTE module performs an autonomous rejection, and the upl...

Abstract

The invention relates to a coexistence interference indicating method in long term evolution (LTE) trigger equipment and user equipment (UE), wherein an uplink timer T, a downlink timer T, an uplink counter N and a downlink counter N are arranged in an LTE module in the UE, the LTE module actively obtains N<MAX DL> and N<MAX UL>, the timing periods of the T and the T are respectively set, and the N and the N are initialized, wherein the T / T is started when the uplink interference / downlink interference is generated in the first time, the LTE module carries out once self rejection when the uplink interference is caused by the LTE module on a non-LTE module, N is added to one; the non-LTE module carries out once self rejection when the downlink interference is caused by the non-LTE module on the LTE module, N is added to one; when a certain timer is not timeout, and in addition, the value of the corresponding counter is greater than the corresponding maximum value, the IDC interference indication is triggered, and in addition, the counter is restarted; and the corresponding counter is restarted when the timer is timeout. The technical scheme provided by the invention can solve the uplink interference triggering problem caused by the LTE module on the non-LTE module.

Description

technical field [0001] The present invention relates to network communication technologies, in particular to a method for triggering an indication of coexistence interference in a device in LTE and a UE. Background technique [0002] The 3rd Generation Partnership Project 3GPP has determined that in order to solve the In-Device Co-existence (IDC, In-Device Co-existence) interference problem, there are currently two available mechanisms: a network-controlled UE-assisted mechanism and a UE-autonomous mechanism. For the network-controlled UE (User Equipment) assistance mechanism, when the UE internally evaluates and determines that IDC interference avoidance measures need to be taken, the UE sends an IDC indication to inform the network of this information and other assistance information. Therefore, whether to trigger the IDC indication timely and correctly becomes the key to solving the IDC interference problem. [0003] The existing mechanism directly uses the measurement r...
