Description
Technical Field
The present invention relates to the field of communications, and in particular, to a measurement reporting method and device for avoiding in-device coexistence interference.
Background
The smart terminal generally supports multiple radio access technologies, such as supporting LTE (Long term evolution) and ISM (Industrial, Scientific, and Medical frequency bands) (including bluetooth, wireless local area network, etc.), supporting LTE and GPS (Global positioning system) positioning technologies, and the like. For these radio access technologies in the same device, if a single radio frequency module design is used, the interference between each other cannot be avoided, especially in the application scenario with partially overlapping frequency bands or adjacent very close frequency bands, for example, as follows:
A) the problem of device coexistence interference between the high frequency part of the LTE Band 40(2300MHz-2400MHz) and the ISM Band (e.g., 2.4GHz-2.4835GHz for WLAN) access technologies is shown in Table 1
TABLE 1
| LTE | ISM | Interference state |
| Harvesting machine | Hair-like device | LTE: interference by ISM, ISM: normal operation |
| Hair-like device | Harvesting machine | LTE: normal operation, ISM: interfered by LTE |
| Harvesting machine | Harvesting machine | No co-existence interference problem |
| Hair-like device | Hair-like device | No co-existence interference problem |
B) The device coexistence interference problem between the LTE Band 13(777-787MHz, 746-756MHz) or Band 14(788-798MHz, 758-768MHz) and GPS (1575.42 MHz, for example) technologies is shown in Table 2
TABLE 2
| LTE | GPS | Interference state |
| Hair-like device | Harvesting machine | LTE: normal operation, GPS: interfered by LTE |
| Harvesting machine | Harvesting machine | No co-existence interference problem |
It should be noted that when a Wireless system is in an IDLE state (LTE listening paging, WLAN (Wireless Local Area Network) listening beacon, bluetooth sniff), there is no interference to other systems.
When a strong interference source exists in the terminal, the communication between the terminal and the serving cell is maintained, so that the process of switching the network control terminal to other cells based on the measurement report of the terminal is difficult to realize, and the wireless link of the terminal is finally failed; even if the terminal selects the connection reestablishment process after the link fails, a larger service interruption delay is generated, which is not beneficial to improving the user experience.

Detailed Description
To more clearly describe the measurement reporting method for avoiding the in-device coexistence interference provided in the embodiment of the present invention, first, a measurement mechanism of LTE in the prior art is described.
In the LTE system, a base station sends measurement configuration information to a terminal through an RRC (Radio Resource Control protocol) signaling, and the terminal performs measurement (common frequency, pilot frequency, and the like) according to the content of the measurement configuration information and then reports the measurement result to a network.
(1) The network performs measurement configuration by using an RRC connection reconfiguration process, and the organization structure of the measurement configuration information is as follows:
measurement object (measurement object): taking a frequency point as a basic unit, wherein each configured measuring object is an independent frequency point and has an independent measuring object Identification (ID);
reporting configuration (report configuration): and according to the trigger type, the method is divided into event trigger reporting and periodic trigger reporting, and each reporting configuration has an independent ID. The event Trigger type reporting configuration is configured to allocate a threshold value of an event and a duration (Time to Trigger) satisfying a Trigger condition, and the periodic Trigger type reporting configuration is configured to allocate a purpose of periodic Trigger (for example, reporting a CGI). At present, there are five common-frequency/different-frequency measurement events in the LTE system, including:
event A1(Serving beacons beta th an threshold, Serving cell channel quality greater than threshold)
Event A2(Serving clusters word threshold, Serving cell channel quality less than threshold)
Event A3 (neighbor beacons offset between the serving cell channel quality)
Event A4 (neighbor beacons beta and threshold, neighbor cell channel quality greater than threshold)
Event A5(Serving beacons word and channel threshold1 and neighbor beacons beta and threshold 2. Serving cell channel quality is less than threshold1, while neighbor cell channel quality is greater than threshold 2)
Event B1(Inter RAT neighbor beacons gap threshold, Inter-system neighbor cell quality greater than threshold)
Event B2(Serving beacons word and times beacon threshold1 and inter RATNeighbour better than threshold 2. the quality of the Serving cell is less than the threshold1, and the quality of the neighbor cells of different systems is more than the threshold 2)
Measurement identity (measurement ID): the single ID can connect a measurement object and report configuration at the same time. If the threshold for starting measurement is reached, the terminal judges whether to carry out the measurement according to the existence of the measurement identifier;
other parameters: other parameters may also be included, such as measurement configuration, measurement turn-on threshold, and speed status parameters.
(2) There are three triggering modes for measurement reporting: event-triggered reporting, periodic reporting, and event-triggered periodic reporting. The three modes are distinguished according to the combination of various parameters in the reporting configuration.
(3) Measuring the main content of the report message: each measurement report message can report only the content corresponding to one measurement identifier, namely, the cell meeting the relevant reporting configuration under one frequency point, and the measurement report message contains the following contents: the measurement identifier, the measurement parameters (Reference Signal Receiving power, Reference Signal Receiving Quality) and RSRP (Reference Signal Receiving Quality) of the cell, the physical layer cell ID of the neighbor cell satisfying the condition, etc., whether to report the measurement parameters and CGI of each neighbor cell depends on whether the network configures the terminal to report these information.
(4) The measurement reporting process comprises the following steps: under each measurement identifier, the method comprises two processes of measurement evaluation and organization reporting:
a) measurement and evaluation: the terminal finds a cell which meets the reporting configuration in a certain measuring object through measurement, carries out evaluation, and is contained in a reporting list when the cell meets the access condition within a certain Time (Time To Trigger); once a new cell enters a reporting list, triggering a reporting process;
b) and (3) organization reporting: namely, in the process of filling in the measurement report message, the measurement identifier, the measurement information of the local cell and the measurement information of the neighboring cell need to be filled in. The process of obtaining the measurement information of the adjacent cells is that the cells contained in the report list in a) are sorted according to the quality of the report measurement quantity given in the configuration, and the measurement report information is filled in the sequence from top to bottom.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be obtained by a person skilled in the art based on the embodiments of the present invention without any inventive step belong to the scope of the embodiments of the present invention.
Example one
An embodiment of the present invention provides a measurement reporting method for avoiding in-device coexistence interference, as shown in fig. 1, including:
step 101, a terminal acquires a pre-interference frequency band of a current working system;
and 102, the terminal processes the measurement of the cell corresponding to the pre-interference scrambling section according to the configured strategy and sends a measurement report message according to the processed measurement result.
The said terminal processes the measurement of the cell corresponding to the pre-interference scrambling segment, and the sending the measurement report message according to the processed measurement result includes: when the terminal works in the pre-interference frequency band, setting the measurement result of the serving cell to be the lowest, or subtracting a preset value from the measurement result; judging whether to send a measurement report message according to the measurement result and the configured measurement event, and sending the measurement report message when the judgment result is yes; and when the terminal works in the pre-interference frequency band, the terminal does not measure all adjacent cells in the pre-interference frequency band.
Further comprising: when the terminal works outside the pre-interference frequency band, setting the measurement result of the cell corresponding to the pre-interference scrambling segment to be the lowest, or subtracting a preset value from the measurement result, or not measuring the cell corresponding to the pre-interference scrambling segment; and the terminal sends a measurement report message which carries the processed measurement result.
The current working system is specifically a long term evolution LTE system.
The measurement result is specifically reference signal received power RSPP and/or reference signal received quality RSRQ.
Example two
A second embodiment of the present invention provides a measurement reporting method for avoiding in-device coexistence interference, as shown in fig. 2, including:
step 201, the terminal judges that the intra-device interference will occur, and acquires the pre-interference frequency band of the current working system.
Specifically, the interference between the LTE system and the ISM is described as an example below. At this time, the terminal LTE system is in an RRC connected state.
The terminal LTE system works in a frequency band which can generate interference in equipment, and the frequency band comprises one or more of the following conditions:
LTE to ISM interference, such as high frequency 20MHz for Band 40 (TD-LTE to ISM interference), low frequency 20MHz for Band 7 (FDD UL to ISM interference);
ISM to LTE interference, such as high frequency 20MHz of Band 40 (ISM to LTE interference);
LTE interference to GPS, such as Band 13 and Band 14.
Other wireless technologies (WLAN, bluetooth or GPS) in the terminal, which may generate the in-device interference, are prepared for data transmission and operate in a frequency band in which the in-device interference may be generated, including one or more of the following situations:
LTE to ISM interference, such as low frequency 20MHz in ISM band (TD-LTE to ISM interference), high frequency 20MHz in ISM band (FDD UL to ISM interference);
ISM to LTE interference, such as low frequency 20MHz in the ISM band (ISM to LTE interference);
LTE interferes with GPS, such as GPS operating at 1575.42 MHz.
Taking the interference of the ISM on the LTE system as an example, after the terminal receives the indication that the WLAN is about to enter the working state when the terminal is powered on, the corresponding pre-interference frequency band is obtained according to the analysis. It should be noted that the pre-interference scrambling segment refers to a potential interference frequency band when an interference source (e.g., ISM transceiver) is powered on and enters a standby state without performing data scheduling transmission, for example, a high-frequency 20MHz pre-interference frequency band of the LTE frequency band 40.
Step 202, the terminal processes the measurements.
Specifically, for a terminal currently operating in the pre-interference scrambling segment, there are the following three aspects when it performs measurement:
firstly, the measurement result (for example, RSRP (Reference Signal Receiving power) and RSRQ (Reference Signal Receiving Quality) value) of the serving cell is specially processed, and the specific methods include the following two methods:
the RSRP and the RSRQ values are the lowest values, namely-140 dBm and-19.5 dB respectively;
the actual measured RSRP and RSRQ values are both subtracted by an empirical dB value of the interference within the device.
After the measurement result of the serving cell is processed, reporting of an A2 event of the serving cell can be triggered, and then the network can configure measurement gap required by the measurement of the pilot frequency and the different systems and execute the measurement of the pilot frequency and the different systems; and reporting the different-frequency and different-system cells can be triggered more quickly, and the auxiliary base station switches the different-frequency and different-system cells, for example, event measurement such as A3/A5/B1/B2 is configured on the different-frequency and different-system cells, and the quality of a service cell is degraded, so that the terminal can report the adjacent cells of the different-frequency and different-system cells as early as possible when the event reporting condition is evaluated.
And secondly, for all adjacent cells in the pre-interference frequency band (including the same frequency and a part of different frequencies), the terminal does not measure and does not generate measurement report.
And thirdly, for the pilot frequency and different system adjacent cells outside the pre-interference frequency band, no special processing is carried out on the measurement result.
When a terminal which works outside a pre-interference scrambling section at present measures, all adjacent cells in a pre-interference frequency band are measured by adopting the following scheme:
the terminal does not perform pilot frequency measurement on the frequency points in all the pre-interference frequency bands and does not generate measurement report;
the terminal measures the adjacent cells in the pre-interference frequency band, specially processes the measurement result (RSRP or RSRQ value) (the processing mode can adopt the processing mode mentioned in the first step), and then judges whether the configured event trigger reporting condition is met;
the terminal measures the adjacent cells in the pre-interference frequency band, and specially processes the cell measurement result (RSRP or RSRQ value) meeting the event trigger reporting condition (the processing mode can adopt the processing mode in the first step);
the terminal does not carry out any additional processing on the measurement results of the different-frequency and different-system adjacent cells except the pre-interference scrambling section.
The premise of processing the measurement results is that the frequency point starts measurement, namely the frequency point is controlled by an s-Measure mechanism of the UE, the quality of a service cell in the pre-interference scrambling segment is processed, and the condition that a serving cell is lower than the s-Measure can be triggered as early as possible, so that the base station can perform more timely pilot frequency measurement and the configuration of the required gap.
Step 203, the terminal sends the measurement report message, and the network side switches the cell of the terminal according to the measurement report message.
Specifically, if the terminal works in the pre-interference scrambling section, the network side cuts the terminal away from the pre-interference scrambling section according to the measurement report message; and if the terminal does not work in the pre-interference scrambling section, the network side avoids switching the terminal to a cell corresponding to the pre-interference scrambling section according to the measurement report message.
And step 204, after the terminal successfully avoids the pre-interference frequency band, informing the ISM transceiver to enter a normal working state.
EXAMPLE III
A third embodiment of the present invention provides a measurement reporting method for avoiding in-device coexistence interference, as shown in fig. 3, including:
step 301, the terminal determines that the intra-device interference will occur, and acquires a pre-interference frequency band.
This step is the same as step 201, and reference may be made to step 201.
Step 302, the terminal notifies the LTE network side of the pre-interference frequency band through a new RRC procedure, and the LTE network side switches the terminal away from the pre-interference scrambling band according to a new RRC notification message.
Step 303, after the terminal successfully avoids the pre-interference frequency band, the terminal notifies the ISM transceiver to enter a normal working state.
Example four
A fourth embodiment of the present invention provides a measurement reporting method for avoiding in-device coexistence interference, where a terminal currently operates in an LTE cell 1, a center frequency point of the terminal is F1, and a network configures measurement of same-frequency and different-frequency F2 and F3 for the terminal, as shown in fig. 4, the method includes:
step 401, the terminal learns that the WLAN in the device is about to enter a working state when being powered on, and determines that F1 will be interfered by the WLAN and that F2 and F3 are not interfered by the WLAN;
step 402, the terminal does not measure the neighboring cell on the frequency point F1, and subtracts an offset (compensation) value from the RSRP value of the serving cell, where the offset value is an empirical dB value of interference of the WLAN in the device to the LTE system; no processing is done on the cell measurements and their results on frequency points F2 and F3.
Step 403, the terminal triggers a measurement report message to indicate that cell 2 (based on A3 event configured on frequency point F2) under the network frequency point F2 is higher than a threshold of serving cell quality, and the base station switches the terminal from cell 1 to cell 2 under frequency point F2 after receiving the measurement result.
In step 404, after the terminal determines to cut away from the frequency point F1, the terminal notifies the WLAN that the WLAN can enter a normal operating state.

step 501, the terminal learns that the WLAN in the device is about to enter a working state when being powered on, and determines that F2 will be interfered by the WLAN and that F1 and F3 are not interfered by the WLAN.
Step 502, when the terminal is measuring, processing all cell measurement results under the frequency point F2 into the lowest value, namely, modifying the RSRP value to-140 dBm and modifying the RSRQ value to-19.5 dB; and cell measurement results under the same frequency and the frequency point of F3 are not processed.
Step 503, after the network subsequently receives the measurement report that the quality of the serving cell 1 is poor and the signal quality of the cell 3 is better at the frequency point F3, the network instructs the terminal to switch to the cell 3 at the frequency point F3.
In step 504, after the terminal determines to cut away from the frequency point F1, the terminal notifies the WLAN that the WLAN can enter a normal operating state.

Step 702, the terminal subtracts an offset value from a measurement result RSRP value of a serving cell (cell 1), wherein the offset value is an empirical dB value of interference of a WLAN in the device to the LTE system; and then, the terminal triggers an A2 event that the quality of the service cell is poor to report to the network, and the network configures measurement and measurement gap on same frequency and different frequency F2 and F3 for the terminal after receiving the A2 report. And the terminal judges that the frequency points F2 and F3 are not interfered by the WLAN and does not process the measurement.
