Description
Technical Field
The present invention relates to network communication technologies, and in particular, to a method for triggering an in-device coexistence interference indication in LTE and a UE.
Background
The third generation partnership project 3GPP has determined that to solve the In-Device Co-existence (IDC) interference problem, there are currently two mechanisms available: the network controls the UE-assisted mechanism and the UE-autonomous mechanism. For a mechanism for assisting a network control User Equipment (UE), when the UE performs an internal evaluation and determines that an IDC interference avoidance measure needs to be taken, the UE sends an IDC indication to inform the network of the information and other assistance information. Therefore, whether to trigger IDC indication timely and correctly becomes the key to solve IDC interference problem.
Existing mechanisms directly use LTE R8/9 reference Signal received Quality (rsrqrreference Signal Receiving Quality) measurements as triggers to trigger IDC interference indications. LTE R8/9RSRQ measurements relate to received signal/interference strength from base stations and channel effects experienced by UEs. Due to the presence of IDC interference, the effective noise level will increase when the ISM radio transmits a signal.
The current protocol has no UE-implemented restrictions on RSRQ calculation, so the UE can take any samples based on its proprietary algorithm to calculate RSRQ, although those samples may not all overlap with ISM transmission time.
The coexistence interference levels of non-LTE wireless technologies may be different at different RSRQ measurement sampling times, which may cause problems with untimely or frequent triggering; even if the measurement result can be guaranteed to be correct, it is difficult to judge whether the result is caused by other external interference or interference from a coexistence technology inside the UE, which may cause frequent triggering problems, thereby affecting the throughput of the LTE side and further affecting the user experience; even if the above problem is improved by improving the existing R8/9RSRQ measurement method, the triggering method based on the measurement result can only determine the interference of other wireless technologies to LTE downlink reception, but cannot solve the problem of triggering LTE uplink interference to other wireless technologies.
In summary, although the existing implementation scheme basically implements a function of triggering the UE to send the IDC interference indication to the network side, the problem of untimely and frequent triggering exists, and only the interference of other wireless technologies to LTE downlink reception can be determined, but the problem of triggering the uplink interference of LTE to other wireless technologies cannot be solved.

Detailed Description
Fig. 1 is a flowchart of a method for triggering IDC interference indication in LTE according to the present invention; as shown in fig. 1, the non-LTE module in the present invention is a wireless module other than the LTE module, such as a bluetooth module, an infrared module, a WIFI module, and the like.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Based on the time and intensity criteria of the IDC, there are 6 cases, respectively, scene 1 to scene 6. Therein, IDC interference can be classified into 4 types in terms of time: sustained, burst, sparse and none; secondly, IDC interference can be classified into 3 types in terms of strength: too strong, weak and none.
Fig. 2 is an IDC interference situation that may exist in LTE. As shown in fig. 2, in the present invention, when the UE considers interference in both scenario 1 and scenario 3, i.e. there is persistent too strong interference, through internal evaluation, the UE will perform autonomous rejection. Wherein the UE performing autonomous denial comprises: the LTE module in the UE executes autonomous rejection, namely the LTE module does not respond to uplink scheduling of a network side once; and the LTE module in the UE informs the non-LTE module to execute autonomous rejection, namely the non-LTE module suspends the occurrence of data once.
Fig. 3 is a detailed flowchart of a method for triggering IDC interference indication in LTE according to the present invention; as shown in figure 3 of the drawings,
step 301, the LTE module obtains the maximum autonomous denial times N of the LTE module from the base stationMAX DLAnd acquiring the maximum autonomous rejection number N of the non-LTE module from the non-LTE moduleMAX UL。
In step 301, a base stationBased on the link adaptive simulation of the physical downlink control channel and the physical uplink shared channel, under the condition that the throughput of the LTE module and the link adaptive function of the physical downlink control channel and the physical uplink shared channel are not seriously influenced, the critical value of the maximum autonomous rejection times which can be borne by the LTE module, namely the maximum autonomous rejection times N of the LTE module, is determinedMAX DL(ii) a The method specifically comprises the following steps:
autonomous rejection by the LTE module may result in: 1) PUSCH resources allocated to an interfering UE cannot be scheduled by another UE, resulting in reduced cell throughput; 2) when the eNB attempts to persistently schedule the UE without transmitting any data, the PDCCH load increases; 3) link adaptation failure; when the UE rejects uplink transmission, the network may cause the eNB to not know the cause of PUSCH transmission failure, trigger the eNB to change its PUSCH link adaptation for the UE, resulting in excessively pessimistic link adaptation, and thus poor transmission throughput occurs; or the UE does not transmit in the uplink, the eNB may consider that the UE exceeds the UL grant, thus changing the link adaptation of its PDCCH, causing unnecessary loss. Therefore, we can determine the acceptable cell throughput, PDCCH load and PUSCH empirically by considering the above 3 factors together&The ratio of PDCCH transmission failure is simulated, and in the preferred embodiment of the invention, the PUSCH&The PDCCH transmission failure rate is 1%, and a critical value of the maximum autonomous denial times that the corresponding LTE module can bear, that is, the maximum autonomous denial times N of the LTE module is obtainedMAX DL。
In the initial stage of base station construction, the base station obtains N corresponding to different service types based on adaptive simulation according to different service types to be processed by UEMAX DLValue of N corresponding to different service typesMAX DLThe value is stored in the base station; UE obtains N currently processing service from broadcast message sent by base stationMAX DLThe value is obtained.
In other embodiments of the present invention, the service types to be processed by the LTE module of the UE, such as VoIP service, are respectivelyObtaining N corresponding to each service through link self-adaptive simulation of a physical downlink control channel and a physical uplink shared channelMAX DLA value; or setting N corresponding to each service in related protocolMAX DLValue, the LTE module can read the corresponding N in the related protocol according to the current serviceMAX DLA value; or a maximum autonomous rejection number table is set in the eNB, and each service processed by the LTE module corresponds to one N in the maximum autonomous rejection number tableMAX DLThe eNB informs the UE of the table through broadcast information, and when the LTE module processes the service, the corresponding N is found in the maximum autonomous rejection number tableMAX DLThe value is obtained.
In step 301, the maximum autonomous denial number N of the non-LTE module needs to be determinedMAX UL. The method comprises the steps that the autonomous rejection of the non-LTE module possibly causes the reduction of the traffic and the receiving error of the non-LTE module, and the critical value of the maximum autonomous rejection times which can be borne by the non-LTE module, namely the maximum autonomous rejection times N of the non-LTE module, is determined according to the acceptable traffic and the error rate of the non-LTE moduleMAX UL。
Step 302, setting an uplink timer T according to the service to be processed by the non-LTE moduleULAccording to the timing period of the LTE module, a downlink timer T is set according to the service to be processed by the LTE moduleDLThe timing period of (c).
In step 302, the uplink timer TULCorresponds to the traffic being processed by the non-LTE module, and in one embodiment of the present invention, the uplink timer T is set to be equal to or less than a predetermined valueULThe timing period of (a) is a multiple of the mode period of the traffic. When a non-LTE module starts to work, the LTE module actively acquires an uplink timer T corresponding to the current service from the non-LTE moduleULThe timing period of (c).
In an embodiment of the present invention, the downlink timer T is set according to the service to be processed by the LTE moduleDLThe timing cycle of (a) is specifically: a service schedule is set in the UE,each service to be processed by the LTE module corresponds to a time value in a service time table; when the LTE module is processing the service, finding the time value corresponding to the service in the service time table, and setting a timer TDLThe timing period of the time setting unit is the time value corresponding to the service.
Step 303, initialize the up counter NULDown counter NDL。
In step 304, the LTE module determines whether the currently generated interference is the first interference generated after initializing the counter. If so, go to step 305; if not, proceed to step 306.
305, when the LTE module causes uplink interference to the non-LTE module for the first time, starting an uplink timer TULThe LTE module performs one autonomous rejection, namely the LTE module does not respond to the uplink scheduling of the base station once; and an up counter NULAdding 1 to the value of (c);
when the non-LTE module causes downlink interference to the LTE module for the first time, a downlink timer T is startedDLThe LTE module informs the non-LTE module to execute one-time autonomous rejection, namely the non-LTE module suspends the occurrence of data once; and a down counter NDLPlus 1.
Step 306, when the LTE module causes uplink interference to the non-LTE module, the LTE module performs an autonomous rejection, that is, the LTE module does not respond to uplink scheduling of the base station once, and the uplink counter N is set to be equal to the uplink scheduling counter NULAdding 1 to the value of (c); wherein the interference is not restarting up counter NULAnd the last uplink interference.
When the non-LTE module causes downlink interference to the LTE module, the LTE module informs the non-LTE module to execute one-time autonomous rejection, namely the non-LTE module suspends the occurrence of data once, and a downlink counter NDLAdding 1 to the value of (c); wherein the interference is not restarting the downlink counter NDLAnd the latter first downlink interference.
Step 307, the LTE module determines whether a timer is overtime; if the timer is determined to be timed out, step 303 is performed, otherwise, step 308 is performed.
In step 307, if the timer times out, the counter is reinitialized for the next round of IDC interference triggering procedure.
308, the LTE module determines whether the value of the counter is greater than the maximum value corresponding to the counter; if so, go to step 309, if not, go back to step 306.
In step 308, due to the uplink timer TULDownlink timer TDLNone have timed out; if the up counter NULIs greater than NMAX DLOr down counter NDLIs greater than NMAX UL(ii) a The triggered IDC interference indication condition is met.
Step 309, IDC interference indication is triggered. That is, the UE sends an IDC interference indication to the base station, and the base station may perform IDC interference coordination according to the IDC interference indication.
After step 309, the next round of IDC interference triggering is performed. I.e., proceed to step 303, the counter is reinitialized.
