Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a blind configuration method, apparatus, device, and storage medium for a secondary carrier. Background Technology

[0002] Carrier aggregation (CA) is a wireless communication technology used to increase data transmission rate and spectral efficiency. It allows terminals to use multiple physical carriers (including one primary carrier and several secondary carriers) simultaneously for data transmission.

[0003] In existing carrier aggregation technologies, there are generally two methods for configuring secondary carriers: one is a measurement-based secondary carrier configuration method, and the other is a blind configuration method. Blind configuration means that the configuration scheme for the secondary carrier is predetermined during the carrier planning stage. When it is necessary to configure a secondary carrier for a terminal, a pre-defined carrier is selected and configured as the terminal's secondary carrier according to the predetermined blind configuration scheme.

[0004] The existing blind configuration method for secondary carriers cannot guarantee the signal quality of the selected secondary carriers because the secondary carriers are preset. This may result in poor signal quality of the secondary carriers after configuration and activation, failing to achieve the effect of enhancing signal coverage quality. Summary of the Invention

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0054] Carrier aggregation (CA) is a wireless communication technology used to increase data transmission rate and spectral efficiency. It allows terminals to use multiple physical carriers (including one primary carrier and several secondary carriers) simultaneously for data transmission.

[0055] In existing carrier aggregation technologies, there are generally two methods for configuring secondary carriers: measurement-based and blind configuration. Blind configuration means that the secondary carrier configuration scheme is pre-defined during the carrier planning phase. When a terminal needs to be configured with a secondary carrier, a pre-defined carrier is selected according to the blind configuration scheme. Measurement-based secondary carrier configuration has a longer latency and is suitable for scenarios where the primary and secondary carriers have different coverage areas, effectively avoiding configuration failures caused by differences in signal quality under different coverage areas. Blind configuration, on the other hand, has a shorter latency and is suitable for scenarios where the primary and secondary carriers have the same coverage area, enabling rapid configuration of LTE (Long Term Evolution) carrier aggregation functionality.

[0056] Existing blind configuration methods for secondary carriers, because the secondary carriers are pre-defined, cannot guarantee their signal quality. This can lead to situations where, after the secondary carriers are configured and activated, the signal quality is poor, failing to enhance signal coverage. For example, during the carrier planning phase, carrier A is aggregated with carriers B and C. When the terminal uses carrier A as the primary carrier, the secondary carrier is directly selected from carriers B and C. Since there are multiple carriers that can be used as secondary carriers, existing technologies typically select one randomly. For instance, carrier B might be randomly selected as the terminal's secondary carrier, but carrier C may actually have better signal quality than carrier B. Therefore, enabling carrier aggregation may not improve the terminal's signal coverage quality.

[0057] To address the aforementioned technical issues, this application proposes a blind configuration method for secondary carriers. By selecting secondary carriers with better signal quality as the secondary carriers of the target terminal based on the secondary carrier information of other terminals, the signal quality of the secondary carriers blindly configured by the terminal is guaranteed, enabling the configured secondary carriers to effectively improve the signal coverage quality of the terminal.

[0058] The technical solution of the blind configuration method for secondary carriers provided in this application will be described in detail below through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other, and the same or similar content may not be described again in different embodiments.

[0059] It should be noted that the entity executing the blind configuration method for secondary carriers provided in this application embodiment is the base station, and correspondingly, the blind configuration device for secondary carriers is also located in the base station.

[0060] Figure 1 A flowchart illustrating a blind configuration method for a secondary carrier provided in this application is shown below. Figure 1 In some embodiments, the blind configuration method for the secondary carrier includes the following steps:

[0061] S101, Obtain the first measurement report reported by the first terminal; wherein, the first measurement report includes the first carrier identifier and the first channel quality of the primary carrier configured by the first terminal.

[0062] In mobile communication technology, terminals periodically measure the strength, quality, and other relevant parameters of the signals received by the serving cell and neighboring cells. Based on these measurements, they periodically report signal measurement data to the base station. This allows the base station to evaluate the terminal's signal quality and optimize and adjust the network accordingly. These periodic reports help network providers monitor network performance and take appropriate measures to improve service quality. Therefore, information about the terminal's configured primary carrier, including its identifier and channel quality, can be obtained from the terminal's periodically reported signal measurement reports.

[0063] Therefore, the first carrier identifier and first channel quality of the primary carrier configured by the first terminal can be obtained through the first measurement report reported by the first terminal.

[0064] S102, within a preset time range, periodically receive second measurement reports reported by multiple second terminals in carrier aggregation state; wherein, the second measurement report includes the second carrier identifier and second channel quality of the primary carrier configured by the second terminal, and the third carrier identifier and third channel quality of the secondary carrier configured by the second terminal; wherein, the second carrier identifier is the same as the first carrier identifier.

[0065] Similarly, utilizing the characteristics of terminal periodic reporting, the second carrier identifier and second channel quality of the primary carrier configured by the second terminal can be obtained from the second measurement report reported by the second terminal. Furthermore, since the second terminal is in carrier aggregation mode, it is also configured with secondary carriers. The third carrier identifier and third channel quality of the secondary carriers configured by the second terminal can also be obtained from the second measurement report.

[0066] The fact that the second carrier identifier is the same as the first carrier identifier indicates that the main carrier configured by the first terminal is the same as the main carrier configured by the second terminal. Only when they have the same main carrier can the auxiliary carrier to be configured by the second terminal be determined.

[0067] S103, for each second measurement report, if the second channel quality in the second measurement report is within the sampling quality range, then the second measurement report is added to the sampling report set as a sampling report; wherein, the sampling quality range is determined based on the first channel quality.

[0068] The sampling quality range is determined based on the quality of the first channel. Specifically, there are roughly two methods for determining the sampling quality range:

[0069] One approach is to adjust the sampling quality range by floating it up or down within a preset range based on the first channel quality. For example, if the first channel quality is the RSRP value of the primary carrier configured for the first terminal, which is -106dBm, and the preset range for fluctuation is 1dBm, then the sampling quality range is [-107dBm, -105dBm].

[0070] Another approach is to divide the sampling quality into intervals based on a preset sampling quality. The preset sampling quality interval is determined by the quality of the first channel. For example, there might be pre-defined sampling quality intervals such as [-115dBm, -113dBm), [-113dBm, -111dBm), [-111dBm, -109dBm), [-109dBm, -107dBm), and [-107dBm, -105dBm]. When the first channel quality is the RSRP value of the primary carrier configured for the first terminal, which is -106.5dBm, the corresponding sampling range is [-107dBm, -105dBm]. The size of the interval can be defined according to specific needs; for example, in the above example, an interval could be 2dBm, or it could be 1dBm, 3dBm, or 5dBm.

[0071] By using the sampling quality range, a second terminal with a similar primary carrier channel quality to the first terminal can be selected, thus obtaining more valuable secondary carrier data.

[0072] S104, based on the third carrier identifier in the sampling report set, obtain several sampling auxiliary carriers; wherein, the same third carrier identifier corresponds to the same sampling auxiliary carrier.

[0073] Carriers with the same identifier belong to the same carrier, while carriers with different identifiers belong to different carriers. Therefore, based on the identifier of the third carrier, the secondary carriers that have appeared in the sampling report can be identified as the secondary sampling carriers.

[0074] S105, based on the sampling report set, obtain the sampling ratio of the third channel quality in each sampling auxiliary carrier that is greater than the first preset threshold.

[0075] The first preset threshold is used to determine whether the channel quality of the secondary carrier is good. Each sampled secondary carrier contains multiple third channel qualities. The proportion of the third channel quality greater than the first preset threshold can reflect the proportion of the sampled secondary carrier with good channel quality. This proportion is used as a reference to select a suitable secondary carrier for the first terminal.

[0076] Furthermore, the first preset threshold is determined based on the specific frequency band and coverage capability of the secondary carrier; different secondary carriers can have different first preset thresholds. For example, if the sampling secondary carrier frequency band is 900MHz, then the first preset threshold can be set accordingly to -105dBm.

[0077] S106, determine the auxiliary carrier of the first terminal according to the sampling ratio of each sampling auxiliary carrier.

[0078] Once the sampling ratio of the third channel quality in each sampling auxiliary carrier is determined to be greater than the first preset threshold, the sampling auxiliary carrier with better signal quality in the carrier aggregation state can be selected as the auxiliary carrier of the first terminal according to the sampling ratio.

[0079] In this embodiment, by acquiring the secondary carrier information of multiple second terminals that are configured with the same primary carrier as the first terminal, and using the signal quality of the secondary carrier when the second terminal and the corresponding secondary carrier are performing carrier aggregation as a reference, the secondary carrier whose signal quality meets the configuration conditions under the carrier aggregation state is selected from the sampled secondary carriers and configured as the secondary carrier of the first terminal, thereby ensuring the signal quality of the secondary carrier configured by the first terminal and ensuring that the first terminal that has completed the secondary carrier configuration and activation can effectively improve the signal coverage quality.

[0080] In some embodiments, the first channel quality includes the RSRP value of the primary carrier configured by the first terminal, and the second channel quality includes the RSRP value of the primary carrier configured by the second terminal; or, the first channel quality includes the RSRP value of the primary carrier configured by the first terminal and the air interface delay, and the second channel quality includes the RSRP value of the primary carrier configured by the second terminal and the air interface delay.

[0081] The first channel quality of the primary carrier configured for the first terminal can be represented by its RSRP value. RSRP (Reference Signal Received Power) is an indicator used in LTE (Long-Term Evolution) wireless communication systems to evaluate the power of the received reference signal, representing the power level of the physical layer reference signal measured in the LTE network. RSRP is measured in dBm (decibel milliwatts), representing the received reference signal power relative to 1 milliwatt of reference power; a higher value indicates a stronger received signal. RSRP is primarily used to assess the strength of the signal received by the terminal, helping the network optimize and adjust to ensure normal communication connections and data transmission quality. In the LTE system, the terminal can select the optimal base station and perform handover operations based on the measured RSRP value to provide better service coverage and performance. Similarly, the second channel quality of the primary carrier configured for the second terminal is also represented by its RSRP value.

[0082] The first channel quality of the primary carrier configured for the first terminal can be represented by its RSRP value and air interface delay. Air interface delay is added because when RSRP values ​​are the same, the locations of the terminals may differ significantly. For example, a terminal at the cell edge will have a lower RSRP value, and similarly, a terminal in a deep coverage scenario close to the base station, such as inside a building near the base station, may also have a very low RSRP value. In these two cases, the terminals are far apart, leading to high inaccuracies in cross-reference. Therefore, air interface delay is introduced. The air interface delay is lower closer to the base station and higher further away. Thus, the air interface delay can be used to filter out second terminals located close to the first terminal, obtaining a more valuable reference for the third channel quality of the secondary carrier, further improving the accuracy of blind configuration of the secondary carrier. Correspondingly, the second channel of the primary carrier configured for the second terminal is represented by its RSRP value and air interface delay.

[0083] Preferably, the third channel quality includes the RSRP value or SINR value of the secondary carrier configured in the second terminal.

[0084] The secondary carrier of the first terminal can be determined by the RSRP value of the secondary carrier configured in the second terminal, or by the SINR value of the secondary carrier configured in the second terminal. The SINR value is used to determine the secondary carrier of the first terminal because situations may arise where the signal strength is good but interference is high; therefore, SINR is used to assess the coverage quality of low- and mid-frequency cells.

[0085] Specifically, SINR (Signal-to-Interference-plus-Noise Ratio) is a metric used in wireless communication systems to evaluate the ratio between the signal and the interference plus noise. It represents the ratio between the received signal power and the interference plus noise power. SINR is usually measured in dB (decibels). A higher SINR value indicates a stronger signal power relative to the interference and noise, which is beneficial for improving the reliability and speed of data transmission.

[0086] Preferably, the air interface loopback delay between the target terminal sending downlink data packets and receiving the ACK information reported by the target terminal is obtained; wherein the target terminal is a first terminal or a second terminal; the terminal processing delay reported by the target terminal is received; wherein the terminal processing delay is the delay between the target terminal receiving downlink data packets and sending ACK information; the difference between the air interface loopback delay and the terminal processing delay of the target terminal is divided by two to obtain the air interface delay of the target terminal.

[0087] The air interface loopback delay refers to the time interval between the base station sending a downlink data packet and the base station receiving the ACK information reported by the terminal. Specifically, the air interface loopback delay can be the average value of the air interface loopback delay over a preset time period. Furthermore, the air interface loopback delay in this embodiment has the following differences: the statistical starting point for the air interface loopback delay is from the start of downlink data packet transmission, excluding scheduling delay; the average air interface loopback delay is only calculated for a single successful transmission, i.e., when the ACK information reported by the terminal is received on the first transmission. The air interface loopback delay of successfully retransmitted data packets is not included in the average calculation (here, the delay calculation is mainly for location estimation, therefore focusing on wireless transmission delay; successful retransmission includes retransmission, rescheduling, processing delay, etc., and therefore is not included in the statistics).

[0088] Terminal processing latency is the estimated time interval between receiving a downlink data packet and sending an ACK message. It can be determined by the base station based on the IMEI (International Mobile Equipment Identity) to identify the specific terminal model, or a single estimated value can be used for all terminals.

[0089] Specifically, ACK (Acknowledge character) is a transmission control character sent by the receiving station to the sending station in data communication. It indicates that the received data has been acknowledged as successfully received. In the TCP / IP protocol, if the receiver successfully receives data, it will reply with an ACK signal. Typically, the ACK signal has its own fixed format and length, and is sent by the receiver to the sender.

[0090] Specifically, the air interface delay satisfies the following formula:

[0091] Tr=(TRTT-Tue) / 2

[0092] Where Tr represents air interface latency, TRTT represents air interface loopback latency, and Tue represents terminal processing latency.

[0093] exist Figure 1 Based on the embodiments shown, the following is combined with Figure 2 The technical solution of the above-mentioned blind configuration method for secondary carriers will be further introduced.

[0094] Figure 2 A flowchart illustrating another blind configuration method for secondary carriers provided in this application embodiment is shown below. Figure 2 In some embodiments, the blind configuration method for the secondary carrier includes the following steps:

[0095] S201, Obtain the first measurement report reported by the first terminal; wherein, the first measurement report includes the first carrier identifier and the first channel quality of the primary carrier configured by the first terminal.

[0096] S202, within a preset time range, periodically receive second measurement reports reported by multiple second terminals in carrier aggregation state.

[0097] S203, for each second measurement report, if the second channel quality in the second measurement report is within the sampling quality range, then the second measurement report is added to the sampling report set as a sampling report.

[0098] S204, based on the third carrier identifier in the sampling report set, obtain several sampling auxiliary carriers; wherein, the same third carrier identifier corresponds to the same sampling auxiliary carrier.

[0099] It should be noted that the execution process of steps S201-S204 is the same as that of steps S101-S104, and will not be repeated here.

[0100] S205, for each sampling report, determine the corresponding secondary sampling carrier based on the third carrier identifier in the sampling report, and increment the total sampling amount of the secondary sampling carrier by one.

[0101] In this process, a sampling report is selected, and based on the third carrier identifier in the sampling report, a sampling auxiliary carrier with the same identifier is found, and the total sampling amount of this sampling auxiliary carrier is incremented by one.

[0102] S206, if the quality of the third channel in the sampling report is greater than the first preset threshold, then the sampling quantity of the secondary carrier is increased by one.

[0103] Specifically, it is determined whether the quality of the third channel in the sampling report is greater than the first preset threshold. If it is greater than the first preset threshold, the sampling quantity of this sampling auxiliary carrier is increased by one.

[0104] S207, Based on the ratio of the number of samples of the secondary carrier to the total number of samples, the sampling ratio of the secondary carrier is obtained.

[0105] Finally, the sampling ratio of this secondary carrier is obtained by dividing the number of samples taken by the total number of samples. The sampling ratios of other secondary carriers can be obtained in the same way.

[0106] S208, determine whether the number of sampling secondary carriers is one.

[0107] S209, if the number of sampled auxiliary carriers is greater than one, then determine whether there is a sampled auxiliary carrier with a sampling ratio greater than the second preset threshold.

[0108] S210, if there is a sampling auxiliary carrier with a sampling ratio greater than the second preset threshold, then the total sampling amount of each sampling auxiliary carrier with a sampling ratio greater than the second preset threshold is compared, and the sampling auxiliary carrier with the largest total sampling amount is selected as the auxiliary carrier of the first terminal.

[0109] S211, if there is no sampling auxiliary carrier with a sampling ratio greater than the second preset threshold, then the sampling ratios of each sampling auxiliary carrier are compared, and the sampling auxiliary carrier with the largest sampling ratio is selected as the auxiliary carrier of the first terminal.

[0110] S212, if the number of sampling auxiliary carriers is equal to one, then select the sampling auxiliary carrier as the auxiliary carrier of the first terminal.

[0111] In this embodiment, by comparing and judging the number of sampling auxiliary carriers and the sampling ratio of the sampling auxiliary carriers, a suitable sampling auxiliary carrier is selected as the auxiliary carrier of the first terminal according to different situations, so as to complete the configuration of the auxiliary carrier of the first terminal, which has higher accuracy and ensures the effect of the auxiliary carrier configured by the first terminal.
