Description

Measurement reporting method and terminal of unauthorized carrier, configuration method and base station

Technical Field

The invention relates to the field of communication, in particular to a measurement reporting method and a terminal of an unauthorized carrier, a configuration method and a base station.

Background

In mobile communication systems, cell reselection and handover are important functions thereof. In order to successfully implement cell reselection, the ue (user equipment) needs to measure the signal quality of different cells so as to select a suitable cell for camping. After the UE establishes a connection with the network in a certain cell, the UE still needs to measure the signal quality of its neighboring cell, so as to select a suitable cell for handover, thereby satisfying the mobility requirement.

In a Long Term Evolution (LTE) system, in a connected state, a specific process of measurement is as follows: the network side sends a measurement control message to the UE, where the measurement control message includes a measurement identifier, a measurement object, a report configuration, and other relevant measured attributes. The measurement object includes measurement object attributes (such as carrier frequency, neighbor list, etc.), and the report configuration includes report configuration attributes (such as event trigger or periodic report, event definition of trigger (a1, a2 …), reporting times, etc.). And the UE executes measurement and evaluation according to the measurement object and the report configuration in the measurement control message, and generates a measurement report according to the measurement result and reports the measurement report to the network side. For an event-triggered measurement task, a measurement object is considered To be a measurement object meeting an event-triggered condition when the duration of the measurement object meeting an admission condition of the event (such as the signal quality of the measurement object being better than a threshold) is equal To or greater than ttt (time To trigger). And reporting the measurement report to a network side after the measured object meets the triggering condition of the event.

In order to provide a higher data rate for a mobile user, a Long Term Evolution advanced (Long Term Evolution advanced, LTE-a for short) advanced system provides a Carrier Aggregation (CA) technique, which aims to provide a larger bandwidth for a UE with corresponding capability and improve the peak rate of the UE. In LTE, the maximum downlink transmission bandwidth supported by the system is 20MHz, and carrier aggregation is to aggregate two or more Component Carriers (CCs) to support a transmission bandwidth greater than 20MHz and not greater than 100MHz at most. After introducing the carrier aggregation technology, the UE in a connected state may communicate with the source base station through multiple Component Carriers (CCs), and after introducing the CA technology, a Primary serving Cell (Pcell, Primary Cell) and a Secondary serving Cell (Scell, Secondary Cell) are also introduced.

Due to the shortage of frequency spectrum resources and the rapid increase of large-flow services of mobile users, the requirement of adopting high frequency points such as 3.5GHz for hot spot coverage is increasingly obvious, and nodes with low power become a new application scene so as to increase the throughput of users and enhance the mobile performance. However, due to the fact that signal attenuation of high frequency points is relatively severe, coverage of a cell is relatively small, and the cell is not co-sited with an existing cell, at present, a new enhancement scheme is sought by a plurality of companies and operators, and Dual Connectivity is one of the enhancement schemes. A terminal under dual connectivity may stay connected to more than two network nodes at the same time, but the control plane connection has a connection to only one of the cells, e.g. a macro cell. The multiple service nodes of the terminal are multiple base stations, and the time delay between the base stations is not negligible. For example, one network node is a macro base station called MeNB, and another network node is a small cell base station called SeNB.

With the rapid growth of data traffic, licensed spectrum will not be able to withstand such huge amounts of data in the near future; LTE operators consider deploying LTE in Unlicensed spectrum resources (Unlicensed carriers), by which data traffic in licensed carriers is shared. Unlicensed carriers (unlicensed spectrum) refer to spectrum (or carriers) that can be used without authorization under the compliance with government regulations (radio regulations) by a government agency (e.g., the national radio regulatory commission). For example, microwave ovens, remote control toy planes, Wireless mice, Wireless keyboards, Wireless Fidelity (WiFi), and the like all use unlicensed carriers. In some cases, the unlicensed carrier needs to be used by contention. If the base station (including the WiFi access point) does not contend for the resource, the unlicensed carrier cannot be used. The unlicensed carrier and the licensed carrier may be used in a carrier aggregation manner or in a dual connectivity manner, where the unlicensed carrier is generally used as a supplement to data transmission, that is, the licensed carrier is used as a primary serving cell and the unlicensed carrier is used as a secondary serving cell.

The unlicensed carrier resources have great particularity and randomness, in this scenario, a terminal is required to report all Received Signal Strength Indicators (RSSI) that reflect busy and idle degrees on the unlicensed carriers to a certain extent), and assist a base station to perform resource management, for example, carrier channel selection and the like, the reported content includes an average value of sampled RSSIs and a proportional value that the sampled RSSI is higher than a certain specified threshold, but because the pilot resources on the unlicensed carriers need to be obtained and used through contention in the unlicensed carrier environment, the pilot resources include specified relevant signals sent by an eNB for RRM measurement of the terminal, such as CRS and CSI-RS, and the like. If the content of the average value/the ratio value higher than a certain specified threshold of the RSSI is only reported, the base station still cannot obtain a measurement result accurate and reliable enough to be used as a reference, so that the base station cannot make reasonable judgment according to a reliable and accurate measurement report, and call interruption or user communication service experience decline can be generated in severe cases.

In view of the above problems in the related art, no effective solution is currently available.

Detailed Description

The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Example 1

In this embodiment, a method for reporting measurement of an unlicensed carrier is provided, and fig. 1 is a flowchart of a method for reporting measurement of an unlicensed carrier according to an embodiment of the present invention, where as shown in fig. 1, the process includes the following steps:

s102, receiving a measurement control message sent by a base station, wherein the measurement control message carries indication information, and the indication information is used for indicating an unauthorized carrier wave needing to be measured;

s104, measuring a plurality of pilot signals from different target cells on the unauthorized carrier waves indicated by the indication information, and reporting the measurement results of the pilot signals to an air interface protocol layer III;

s106, recording time stamps respectively corresponding to the measurement results of the pilot signals on the air interface protocol layer by layer three;

s108, operating the time difference between every two adjacent time stamps in the recorded time stamps, wherein the operation result is used for indicating the occupation condition of the base station on the unauthorized carrier and the condition that the terminal can receive the measured pilot signal;

and S110, reporting the operation result to the base station.

Optionally, in this embodiment, the measurement reporting method for the unlicensed carrier may be applied to, but not limited to, an LTE system, and may also be applied to all communication systems that need to use radio resources on the unlicensed carrier through contention preemption. And the auxiliary base station eNB acquires the wireless condition of the terminal side through the measurement result of the unauthorized carrier reported by the terminal UE, so that a more reasonable wireless resource selection decision is made for the terminal. If the occupation situation of the unlicensed carrier is obtained, whether to add or delete the radio bearer is determined according to the occupied and relatively idle time patterns.

Optionally, in this embodiment, before receiving the measurement control message sent by the base station, the method may further include, but is not limited to, in a measurement process of a Signal Strength Indication (RSSI) of the terminal UE in a certain period of time during which network configuration is performed, the method includes that a pilot Signal sent by the base station eNB is Received, filtered by the physical layer 1, and then reported to the air interface protocol layer 3 for n results, which are R0 and R1 … Rn-1, respectively, where R0 is a time when a first measurement result reported to the air interface protocol layer 3 after the pilot Signal sent by the base station eNB is filtered by the physical layer 1 on an unauthorized carrier, and the time at this time is assumed to be T0; r1 is the time when the pilot signal transmitted by the base station eNB on the unauthorized carrier wave is filtered by the physical layer 1 and then the second measurement result is reported to the layer 3, and if the time is T1, and so on, the time when Rn-1 is received is Tn-1.

It should be noted that, since the eNB is constrained by an lbt (list Before talk) mechanism, the time when the base station transmits the pilot signal for measurement is uncertain, so that the time when the terminal UE measures the pilot signal and reports to layer three is also uncertain and aperiodic on the time axis. Therefore, in this embodiment, the time difference between every two adjacent timestamps in the measurement result reported by the physical layer, that is, the time difference between two adjacent timestamps is T1-T0, T2-T1, … Tn-1-Tn-2, and the values of the time differences may be the same or different.

Further, the time difference may reflect, to a certain extent, a probability that the base station eNB serves as a transmitting end and may compete to acquire the unlicensed carrier resource. For example, if the time difference values are large, it indicates that the base station eNB side is busy in contention, and the probability that the base station eNB can contend for the unlicensed carrier resource is also low, otherwise, it indicates that the base station eNB side radio resource (e.g., the unlicensed carrier resource) is idle. In addition, if the dynamic range of the time difference values is large, it indicates that the base station eNB can successfully compete to the unlicensed carrier resources with high randomness, otherwise, the time difference values are regular. That is to say, based on the time difference, the base station may not only obtain the radio condition of the UE side, but also more accurately analyze the occupation of the base station on the unlicensed carrier.

Optionally, in this embodiment, a cell in which the terminal resides is different from a cell to be measured covered by the unlicensed carrier. The cell to be tested and the terminal cell covered by the unlicensed carrier may be aggregated, where the aggregation may include but is not limited to at least one of the following: carrier aggregation, dual connectivity.

Optionally, in this embodiment, the above-mentioned operation on the time difference between two adjacent timestamps in the recorded timestamps may include, but is not limited to, at least one of the following:

1) and carrying out averaging operation on the time difference values, and taking the average value of the time difference values as an operation result. For example, based on the n pilot signals transmitted by the base station eNB as an example, the average value of the time difference values is: mean { (T1-T0), (T2-T1),. . . (Tn-1-Tn-2) } ═ Tn-1-T0/(n-1);

2) and performing variance value taking operation on the time difference value, and taking the variance value of the time difference value as an operation result. For example, based on the n pilot signals transmitted by the base station eNB as an example, the variance value of the time difference value is: VAR { (T1-T0), (T2-T1),. . . (Tn-1-Tn-2) };

3) and performing statistical operation on the time difference value, and taking the number of low-delay samples of which the time difference value is less than or equal to a first preset threshold value as an operation result. For example, based on the n pilot signals transmitted by the base station eNB as an example, if the first predetermined threshold is Thresh-1, the number of the time difference values exceeding the eNB configured first predetermined threshold Thresh-1 is counted.

It should be noted that, after filtering the measured pilot signals layer by layer, the terminal reports the measurement results of the pilot signals of layer three, such as effective sampling values, and records the time of each obtained effective sampling value as the time stamp of the corresponding pilot signal.

According to the embodiment provided by the application, the terminal receives the measurement control message sent by the base station, measures a plurality of pilot signals on the unauthorized carrier according to the indication of the indication information which is used for indicating the unauthorized carrier needing to be measured in the measurement control message, and reports the measurement result of the pilot signals to the third layer; recording time stamps respectively corresponding to the measurement results of the pilot signals on the layer three; and operating the time difference between every two adjacent timestamps in the recorded timestamps to obtain an operation result for indicating the occupation condition of the base station on the unauthorized carrier, and reporting the operation result to the base station. Therefore, the base station can make more accurate and reliable decisions by combining with the operation results reported by the terminal, and the problem of call drop caused by the fact that the base station cannot accurately make reasonable decisions in the related technology is solved.

As an alternative, the operation of the time difference between two adjacent time stamps in the recorded time stamps comprises at least one of:

1) and averaging the time difference values, and taking the average value of the time difference values as an operation result.

Specifically, the description is made with reference to the following example, for example, the terminal resides in the cell 1, the working frequency point of the cell 1 is f1, Radio Resource Control protocol (RRC) connection establishment is initiated on the cell 1, and after the RRC connection establishment process is completed, the terminal enters a connected state. Further, the terminal receives indication information in a measurement control message sent by the base station to indicate that the unlicensed carrier is measured, wherein a frequency point of the unlicensed carrier is f 2.

Assuming that the physical layer reports the f2 signal to layer three at T1, and records a timestamp T1; and at T2, the physical layer reports the signal of f2 to layer three, and records a time stamp T2, wherein the time difference between T2 and T1 is 80 ms. At T3, the physical layer reports the signal of f2 to layer three, and records a timestamp T3; the time difference between T3 and T2 is 40 ms. At T4, the physical layer reports the signal of f2 to layer three, and records a timestamp T4; the time difference between T4 and T3 is 40 ms. At T5, the physical layer reports the signal of f2 to layer three, and records a timestamp T5; the time difference between T5 and T4 is 40 ms.

Further, when the measurement ending time indicated by the measurement control message for performing RSSI measurement on f2 is reached, the terminal performs an averaging operation on time differences obtained after the RSSI measurement of f2 reported by all physical layers. That is, the timestamps of 5 pilot signals received in total have 4 time differences of 80ms, 40ms, 40ms, and 40ms, respectively, and the average value is 50ms, then the average value of the results of the above operations can be reported as 50 ms. In addition, the ratio above the specified threshold Thresh is calculated, and assuming that 4/5 is 0.8 at this time, the ratio above the specified threshold Thresh of 0.8 and the average value of the RSSI may also be reported to the base station.

2) And carrying out a variance value operation on the time difference value, and taking the variance value of the time difference value as an operation result.

Assuming that the physical layer reports the f2 signal to layer three at T1, and records a timestamp T1; and at T2, the physical layer reports the signal of f2 to layer three, and records a time stamp T2, wherein the time difference between T2 and T1 is 30 ms. At T3, the physical layer reports the signal of f2 to layer three, and records a time stamp T3; the time difference between T3 and T2 is 50 ms. At T4, the physical layer reports the signal of f2 to layer three, and records a time stamp T4; the time difference between T4 and T3 is 55 ms. At T5, the physical layer reports the signal of f2 to layer three, and records a time stamp T5; the time difference between T5 and T4 is 35 ms. At T6, the physical layer reports the signal of f2 to layer three, and records a time stamp T6; the time difference between T6 and T5 is 70 ms.

Further, when the measurement ending time indicated by the measurement control message for performing RSSI measurement on f2 is reached, the terminal performs a variance value operation on time difference values obtained after the RSSI measurement of f2 reported by all physical layers. That is, the total measurement time of receiving 6 pilot signals has 6 time differences, which are 30ms, 50ms, 55ms, 35ms, and 70ms, respectively, and the variance value is 257.5ms, and then the variance value 257.5ms of the operation result can be reported. In addition, the ratio above the specified threshold Thresh is calculated, and assuming that 4/6 is 0.67 at this time, the ratio above the specified threshold Thresh of 0.67 and the average value of the RSSI may also be reported to the base station.

3) And performing statistical operation on the time difference, and taking the number of low-delay samples of which the time difference is less than or equal to a first preset threshold as an operation result.

Assuming that the physical layer reports a signal of f2 to the third layer at T1, and records a timestamp T1; and at T2, the physical layer reports the signal of f2 to layer three, and records a time stamp T2, wherein the time difference between T2 and T1 is 30 ms. Reporting to layer three at T3, and recording a timestamp T3; the time difference between T3 and T2 is 50 ms. Reporting to layer three at T4, and recording a timestamp T4; the time difference between T4 and T3 is 55 ms. At T5, the physical layer reports the signal of f2 to layer three, and records a time stamp T5; the time difference between T5 and T4 is 35 ms. Reporting to layer three at T6, and recording a timestamp T6; the time difference between T6 and T5 is 70 ms.

Further, when the measurement ending time indicated by the measurement control message for performing RSSI measurement on f2 is reached, the terminal performs a variance value operation on time difference values obtained after the RSSI measurement of f2 reported by all physical layers. That is, the timestamps of a total of 6 pilot signals received have 6 time differences of 30ms, 50ms, 55ms, 35ms, and 70ms, respectively, wherein the number of 50ms lower than or equal to the first predetermined threshold is 3. In addition, the ratio above the specified threshold Thresh is calculated, and assuming that 4/6 is 0.67 at this time, the ratio above the specified threshold Thresh of 0.67 and the average value of the RSSI may also be reported to the base station.

According to the embodiment provided by the application, the result of operating the time difference value between every two adjacent timestamps in the measurement results reported to the layer three by the plurality of physical layers is obtained through the at least one operation, and the result of the operation is reported to the base station, so that the base station can make a more accurate decision by using a more accurate and reliable result.

As an alternative, the operation of the time difference between two adjacent time stamps in the recorded time stamps comprises:

s1, repeatedly executing the following steps to obtain a time difference set until reaching a measurement ending time or an evaluation time window closing time indicated by the measurement control message for measuring the pilot signal: acquiring a current timestamp corresponding to a current measurement result; acquiring a next time stamp corresponding to a next measurement result obtained after the current time stamp; acquiring a time difference value between a current timestamp and a next timestamp, and recording the time difference value into a time difference value set; taking the next timestamp as the next current timestamp;

s2, operating on the time difference values in the set of time difference values.

Specifically, the following example is combined to explain, assuming that the RSSI report layer three current timestamp of f2 currently measured by the terminal is T3, and records a timestamp T3; further, the next time stamp T4 after T3 is acquired, and the time difference between T4 and T3, i.e., 40ms, is acquired. Then, taking the next timestamp T4 after T3 as the next current timestamp, the next timestamp T5 after T4 is acquired, and so on until the measurement end time of RSSI measurement on the pilot signal indicated by the measurement control message is reached.

According to the embodiment provided by the application, the time difference between two adjacent timestamps is acquired, so that the occupation condition of the base station eNB on the unauthorized carrier wave, namely the probability of competing to the unauthorized carrier wave resource as a sending end, and the regularity of successfully competing to acquire the unauthorized carrier wave resource are acquired through the time difference.

As an alternative, measuring multiple pilot signals from different target cells on the unlicensed carrier indicated by the indication information includes:

s1, measuring the signal strength or quality of the pilot signal according to the measurement control message;

s2, when the measured signal strength or quality is greater than a second predetermined threshold, it is determined that a pilot signal is measured.

According to the embodiment provided by the application, the signal strength or the quality of the pilot signal of the unauthorized carrier wave to be measured is measured according to the indication of the indication information in the measurement control message, and the pilot signal is judged to be measured after the measured signal strength or the measured quality is greater than a certain threshold value. Therefore, the time difference of the measuring time of the adjacent pilot signals is obtained by using the measuring time, so that the accuracy and the reliability of the decision making of the base station are improved.

The description is made with specific reference to the following embodiments. Assuming that the base station has coverage providing two cells, the operating frequency point of cell 1 (deployed on the licensed carrier) is f1, the operating frequency point of cell 3 (deployed on the unlicensed carrier) is f 2. Cell 1 and cell 3 may perform carrier aggregation. And carrying out aggregation on the cell 1 and the cells of the unlicensed carriers in a dual-connection mode.

As an optional implementation manner, the terminal resides in the cell 1, and initiates RRC connection establishment on the cell 1, after the RRC connection establishment process is completed, the UE enters a connected state, and the cell 1 is the PCell.
