[0051] Hereinafter, embodiments of the present application will be described in more detail with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.
[0052] In order to improve the technical problem that currently, when a terminal stays at a non-highest coverage level for a long time, the network and the base station often configure a larger number of repetitions and transmission power for it, resulting in relatively large power consumption and latency of the terminal and lower service efficiency. This embodiment provides a communication method, as Figure 1 shown, the method includes:
[0053] Step 101, obtain a first signal quality measurement value of the serving cell where the terminal currently camps.
[0054] For the execution subject of this embodiment, it may be a communication device or a communication device, and may be configured on the terminal device side, such as an electronic device or a chip, etc.
[0055] In some examples, the terminal device may be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may also be an automobile with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver capabilities, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, or may also be a chip or a chip system, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the terminal device. In this embodiment, UE will be used as the main example for illustration.
[0056] In an embodiment of the present application, the network device may be a device such as a base station or a satellite, and no specific limitation is made in the embodiments of the present application. The network device may be an entity on the network side for transmitting or receiving signals. For example, the network device may be a communication satellite, an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, etc. The embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the network device. The network device provided by the embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU). Among them, the CU may also be referred to as a control unit. Adopting the CU-DU structure can split the protocol layer of the network device, such as a base station. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.
[0057] In some examples, the first signal quality measurement value can be used to represent the signal strength and quality received by the terminal in a wireless communication system, which helps to implement functions such as wireless network optimization, handover decision-making, resource allocation strategy formulation, and device operating status monitoring. The first signal quality measurement value can include: Reference Signal Received Power (RSRP), which can represent the average power of the cell-specific reference signal received on a specific resource element; Reference Signal Received Quality (RSRQ), which is the ratio of RSRP to the total received interference and noise power (including thermal noise and interference generated by other cells), usually in dB, and can be used to measure signal quality and signal-to-noise ratio; Signal-to-Interference-plus-Noise Ratio (SINR), which can be used to reflect the ratio of the received useful signal strength to all interferences (including co-channel interference, adjacent-channel interference, and other external interferences) and the background noise power; Received Signal Strength Indicator (RSSI), which can be used to reflect the total strength of all radio signals received, rather than just for a specific signal; Error Vector Magnitude (EVM), which can be used to measure the deviation degree between the actually received modulated signal and the ideal modulated signal in a digital communication system; Bit Error Rate (BER), which can represent the ratio of the number of error bits that occur during data transmission to the total number of transmitted bits, and is used to evaluate the error performance after signal demodulation.
[0058] Step 102: Obtain the signal quality threshold value corresponding to the highest coverage level of the serving cell.
[0059] In some examples, the highest coverage level can refer to the coverage area with a coverage level of CL0. Within the coverage area corresponding to the CL0 level in network planning and design, the terminal can receive a strong and stable enough signal to ensure high-quality data transmission and services. Among them, the signal quality threshold value can be the signal quality threshold for dividing the highest coverage level of the serving cell from other coverage levels, and can be used to measure the communication quality and connection stability between the terminal and the base station.
[0060] Step 103: Determine whether the terminal starts cell reselection measurement by comparing the first signal quality measurement value with the signal quality threshold value.
[0061] In the embodiments of the present disclosure, it is possible to determine whether the terminal starts cell reselection measurement by comparing the first signal quality measurement value with the signal quality threshold value. If the first signal quality measurement value is less than the signal quality threshold value, the terminal is not in the highest coverage level of the serving cell, and cell reselection measurement can be started to increase the possibility that the terminal stays in the highest coverage level. The network and the base station configure a larger number of repetitions and transmission power for it, thereby reducing the power consumption and latency of the terminal, and improving the signal quality and service efficiency. If the first signal quality measurement value is not less than the signal quality threshold value, the terminal is in the highest coverage level of the serving cell, and there is no need to start cell reselection measurement, reducing the power consumption and latency caused by cell reselection.
[0062] Compared with the current existing technologies, in this embodiment, first, the first signal quality measurement value of the serving cell where the terminal currently camps is obtained; then, the signal quality threshold value corresponding to the highest coverage level of the serving cell is obtained; and then, by comparing the first signal quality measurement value with the signal quality threshold value, it is determined whether the terminal starts cell reselection measurement. In this embodiment, it is possible to determine whether the terminal starts cell reselection measurement by comparing the first signal quality measurement value of the terminal's serving cell with the signal quality threshold value corresponding to the highest coverage level. If the terminal is not in the highest coverage level of the serving cell, cell reselection measurement can be started to increase the possibility that the terminal stays in the highest coverage level, and reduce the number of repetitions and transmission power configured for it by the network and the base station, thereby reducing the power consumption and latency of the terminal, and improving the signal quality and service efficiency.
[0063] Further, to illustrate the specific implementation process of the method in this embodiment, this embodiment provides a specific method as shown in Figure 2 which includes:
[0064] Step 201, obtain the first signal quality measurement value of the serving cell where the terminal currently camps.
[0065] Optionally, step 201 may specifically include: when the terminal camps in the serving cell in the idle state, obtain the first signal quality measurement value of the serving cell at regular intervals according to the measurement period.
[0066] Exemplarily, when the terminal camps in the serving cell in the idle state, cell reselection measurement can be performed, and the RSRP value of the serving cell can be obtained at regular intervals according to the measurement period, avoiding interference during normal use and reducing the power consumption of the terminal.
[0067] Optionally, if it is not determined that the terminal starts cell reselection measurement after a target number of measurement periods, the first signal quality measurement values recorded within the target number of measurement periods are cleared.
[0068] For example, if after N measurement periods, the detected RSRP values are all greater than the signal quality threshold corresponding to the highest coverage level of the serving cell, the terminal does not initiate cell reselection measurement, and the detected RSRP values within the N measurement periods can be cleared to save the storage space of the terminal.
[0069] Optionally, the target quantity can be obtained from the system message broadcast of the serving cell.
[0070] Among them, the target quantity can be used to determine the number of measurement periods, and the signal quality and residence location of the UE are judged by detecting the first signal quality measurement values of multiple measurement periods, reducing the power consumption of the terminal.
[0071] Step 202: Obtain the signal quality threshold corresponding to the highest coverage level of the serving cell.
[0072] Optionally, the signal quality threshold can be obtained from the system message broadcast of the serving cell.
[0073] Exemplarily, as Figure 3 shown, the network configures signal quality thresholds corresponding to two coverage levels, including coverage level threshold 1 and coverage level threshold 2. The coverage range of the base station is divided into 3 coverage level ranges by these two coverage level thresholds. According to the distance from the terminal to the base station from near to far, it can be divided into coverage level 0 (CL0), coverage level 1 (CL1), and coverage level 2 (CL2). Then the signal quality threshold corresponding to the highest coverage level CL0 of the serving cell where the terminal is located is coverage level threshold 2.
[0074] In a specific application scenario, for a UE supporting coverage levels, the UE can measure the RSRP value of the serving cell where it is located, and then compare it with the signal quality threshold corresponding to the coverage level configured by the network to determine the coverage level to which it belongs. When performing services, the UE can notify the network of the coverage level to which it belongs. The network can then specifically configure parameters suitable for each physical layer transmission channel for the UE, such as the number of repetitions, transmit power value, etc., to ensure that UEs in different coverage levels can perform service processing with the best efficiency, and at the same time can save power and electricity for the UE. Among them, the physical layer transmission channels can include: Physical Random Access Channel (PRACH), Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Push Notification (PUSH), etc.
[0075] Step 203: If the first signal quality measurement value is less than the signal quality threshold, obtain the second signal quality measurement value recorded corresponding to the terminal's last initiation of cell reselection measurement.
[0076] In the embodiments of the present disclosure, through comparison, it is found that if the first signal quality measurement value of the terminal is less than the signal quality threshold, the second signal quality measurement value recorded corresponding to the terminal's last initiation of cell reselection measurement can be further obtained to determine whether the terminal has a position movement. If the terminal has no position movement, cell reselection does not need to be initiated, thereby saving the power consumption of the terminal. Among them, the second signal quality measurement value can be the signal quality measurement value recorded when the terminal last initiated cell reselection measurement, such as: RSRP, RSRQ, SINR, etc.
[0077] Step 204: Determine whether the terminal has a position movement by comparing the second signal quality measurement value with the first signal quality measurement value.
[0078] Optionally, step 204 may specifically include: If the change amount of the first signal quality measurement value relative to the second signal quality measurement value is greater than or equal to the target change amount threshold, it is determined that the terminal has a position movement; if the change amount is less than the target change amount threshold, it is determined that the terminal has no position movement.
[0079] Exemplarily, by comparing the change amount of the first signal quality measurement value relative to the second signal quality measurement value with the target change amount threshold, it can be determined whether the terminal has a position movement. If the change amount is less than the target change amount threshold, it can be determined that the terminal stays in the serving cell for a long time or moves within a small range in the serving cell, and cell reselection measurement does not need to be initiated.
[0080] Optionally, the target change amount threshold can be obtained from the system message broadcast of the serving cell.
[0081] Among them, the target change amount threshold can be used to determine whether the terminal has a position movement.
[0082] Optionally, if the first signal quality measurement value is greater than or equal to the signal quality threshold, or the terminal has no position movement, it is determined that the terminal does not initiate cell reselection measurement.
[0083] In the embodiments of the present disclosure, if the first signal quality measurement value of the terminal is greater than or equal to the signal quality threshold, the terminal is within the coverage range corresponding to the highest coverage level of the serving cell and does not need to initiate cell reselection measurement, saving the power consumption of the terminal. Or after comparing the change amount with the target change amount threshold, it is determined that the terminal has no position movement, and cell reselection measurement does not need to be initiated, thereby saving the power consumption of the terminal.
[0084] Step 205: If the terminal has a position movement, it is determined that the terminal initiates cell reselection measurement.
[0085] Exemplarily, if the terminal moves, it can be determined that the terminal starts cell reselection measurement, enabling the terminal to detect surrounding cells and camp on a cell with a higher coverage level, reducing the number of repetitions and transmission power configured by the network and the base station for it, thereby reducing the power consumption and latency of the terminal and improving the signal quality and service efficiency.
[0086] Optionally, after step 205, it may further include: recording the first signal quality measurement value and clearing the recorded second signal quality measurement value.
[0087] In the embodiments of the present disclosure, after starting cell reselection measurement, the current first signal quality measurement value can be recorded, and the second signal quality measurement value recorded when the cell reselection measurement was started last time can be cleared to save the memory space of the terminal.
[0088] Optionally, after step 205, it may further include: after the terminal performs cell reselection measurement, if the cells that meet the cell reselection R criterion include the serving cell and neighbor cells, determine the target cell for the terminal to handover from the neighbor cells that meet the cell reselection R criterion.
[0089] In the embodiments of the present disclosure, after starting cell reselection measurement, the target cell for the terminal to handover can be determined according to the cell reselection R criterion (cell reselection criterion based on RSRP), enabling the terminal to camp on a cell with a higher coverage level, reducing the number of repetitions and transmission power configured by the network and the base station for it, thereby reducing the power consumption and latency of the terminal and improving the signal quality and service efficiency.
[0090] To illustrate the specific implementation process of this embodiment, the following specific application examples are given, but not limited thereto:
[0091] As Figure 4 shown, the process of the UE performing cell reselection is shown, and the following steps can be executed:
[0092] S2001: The UE is in the idle state in the currently camped serving cell;
[0093] S2002: Regularly measure the RSRP value of the serving cell according to the measurement period;
[0094] S2003: The UE determines whether the measured RSRP value of the serving cell is less than the signal quality threshold of the best coverage level CL0 of this cell, and this signal quality threshold is generally obtained from the system message broadcast of the cell. If not satisfied, the UE continues to periodically measure the RSRP value of the serving cell in the idle state. If satisfied, enter the S2004 condition judgment;
[0095] S2004: Determine whether the UE has moved by calculating whether there is a change in the RSRP value measured by the UE compared to the RSRP value at the time when the cell reselection measurement was last started. If the change amount of the RSRP value measured by the UE is less than the target change amount threshold Delta, it means that the UE has not moved, and there is no need to start the cell reselection measurement again, achieving the purpose of power saving. That is, if the judgment formula is satisfied: measured RSRP value – RSRP value recorded at the last start of cell reselection measurement > Delta, then enter S2005 to start the measurement of same-frequency or different-frequency neighboring cells. Otherwise, return to the S2001 idle state. The Delta value can be obtained from the system message broadcast. At the same time, in order to avoid the UE making circular movements and the change range of the RSRP value is still small, after N S2002 step measurement periods, that is, after N measurement periods, the recorded RSRP value is cleared, and the N value can be obtained from the system message broadcast;
[0096] S2005: Start the cell reselection measurement, and record the current RSRP value for use in the next S2004 step;
[0097] S2006: The UE performs sorting calculations on the measurement values of neighboring cells and the serving cell, determines whether the cell reselection R criterion of the 3GPP standard is satisfied, and if the R criterion is continuously satisfied for the Treselection time, then cell reselection can be performed;
[0098] S2007: The UE performs cell reselection, camps on the cell with the best R criterion, that is, the target cell, and clears the RSRP value recorded at the last start of cell reselection.
[0099] In the embodiment of the present disclosure, the cell reselection R criterion can be further optimized. When the neighboring cell is not the cell with the best R criterion, the serving cell is still the cell with the best R criterion, and the difference between the RSRP of the neighboring cell and the serving cell is small, since the CL threshold of each cell may be configured differently, cell reselection can be performed, enabling the terminal to have the opportunity to try to detect whether there are cells with higher coverage levels around.
[0100] Exemplarily, as Figure 5 shown, the terminal is currently at point C in cell 1 and belongs to the coverage range of the CL1 level in cell 1. When the difference in the RSRP measured between cell 1 and cell 2 is small through the calculation formula (Rs of the serving cell – Rn of the neighboring cell < preset threshold Delta1), cell reselection can be started. Under the CL threshold configuration of cell 2, the terminal is in the coverage range of the CL0 level, enabling the terminal to camp on a cell with a higher coverage level, reducing the number of repetitions and transmission power configured for it by the network and the base station, thereby reducing the power consumption and latency of the terminal and improving the signal quality and service efficiency.
[0101] Compared with the current existing technologies, in this embodiment, when the first signal quality measurement value of the serving cell where the terminal currently camps is less than the signal quality threshold value, the second signal quality measurement value recorded when the cell reselection measurement was last started can be obtained, and then the second signal quality measurement value and the first signal quality measurement value are compared to determine whether the terminal has a location movement. If the terminal has a location movement, it is determined that the terminal starts the cell reselection measurement, enabling the terminal to have the opportunity to detect surrounding cells and camp on a cell with a higher coverage level, reducing the number of repetitions and transmission power configured for it by the network and the base station, thereby reducing the power consumption and latency of the terminal and improving the signal quality and service efficiency.
[0102] Further, as Figure 1 and Figure 2 a specific implementation of the method shown, this embodiment provides a communication device, as Figure 6 shown, the device includes: an acquisition module 31 and a determination module 32.
[0103] The acquisition module 31 is configured to acquire the first signal quality measurement value of the serving cell where the terminal currently camps;
[0104] The acquisition module 31 is configured to acquire the signal quality threshold value corresponding to the highest coverage level of the serving cell;
[0105] The determination module 32 is configured to determine whether the terminal starts the cell reselection measurement by comparing the first signal quality measurement value and the signal quality threshold value.
[0106] In some examples of this embodiment, the determination module 32 is specifically configured to, if the first signal quality measurement value is less than the signal quality threshold value, acquire the second signal quality measurement value corresponding to the last start of the cell reselection measurement by the terminal; determine whether the terminal has a location movement by comparing the second signal quality measurement value and the first signal quality measurement value; if the terminal has a location movement, determine that the terminal starts the cell reselection measurement.
[0107] In some examples of this embodiment, the determination module 32 is specifically configured to, if the change amount of the first signal quality measurement value relative to the second signal quality measurement value is greater than or equal to the target change amount threshold value, determine that the terminal has a location movement; if the change amount is less than the target change amount threshold value, determine that the terminal does not have a location movement.
[0108] In some examples of this embodiment, the determination module 32 is specifically further configured to obtain the target change amount threshold value from the system message broadcast of the serving cell.
[0109] In some examples of this embodiment, the determination module 32 is specifically further configured to, if the first signal quality measurement value is greater than or equal to the signal quality threshold value, or the terminal does not have a location movement, determine that the terminal does not start the cell reselection measurement.
[0110] In some examples of this embodiment, after determining that the terminal starts cell reselection measurement, the determination module 32 is specifically further configured to record the first signal quality measurement value and clear the recorded second signal quality measurement value.
[0111] In some examples of this embodiment, after determining that the terminal starts cell reselection measurement, the determination module 32 is specifically further configured to, after the terminal performs cell reselection measurement, if the cells that meet the cell reselection R criterion include the serving cell and neighboring cells, determine the target cell for the terminal to switch from among the neighboring cells that meet the cell reselection R criterion.
