Description

Technical Field

[0001] [Cross - Reference to Related Applications] This disclosure is based on Chinese Patent Application CN202210763495.8, titled "Method for Measuring Common Signal of Terminal, Terminal and Storage Medium", filed on June 30, 2022. It claims the priority of this patent application, and all the disclosed content is incorporated into this disclosure by reference.

[0002] [Technical Field] This disclosure relates to the field of communication technology, and particularly to a method for measuring common signals of a terminal, a terminal, and a storage medium.

Background Art

[0003] With the deployment and wide application of 5G systems, in order to better meet certain needs such as reducing the complexity and cost of devices, reducing dimensions, and low - energy consumption from terminal IoT applications such as industrial wireless sensors, video surveillance, and wearable devices, Redcap (Reduced Capability) terminals have emerged. For each Redcap terminal within a service cell, when each of these Redcap terminals needs to measure common signals and common channels, they all need to switch from a small - bandwidth dedicated BWP (Bandwidth Part) to a BWP including CD - SSB (Cell Defining - Synchronization Signal Block), and temporarily move the corresponding services to the BWP including CD - SSB. After the measurement is completed, they switch back to the small - bandwidth dedicated BWP again. Thus, a problem occurs where the BWP is frequently switched, resulting in high power consumption of Redcap terminals, easy temporary interruption of services, and potential congestion of the BWP including CD - SSB.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, reducing the frequency of BWP switching, thereby reducing terminal power consumption and business interruption time, and avoiding BWP congestion, including CD-SSB, is an urgent issue that needs to be resolved. [Means for solving the problem]

[0006] According to a second aspect, an embodiment of the present disclosure further provides a terminal comprising memory, a processor, a program stored in the memory and operable on the processor, and a data bus for enabling connection communication between the processor and the memory, which, when the program is executed by the processor, enables the steps of the method for measuring a common signal of a terminal according to any one paragraph of the present disclosure.

[Figure 5] This is a schematic block diagram of the structure of a terminal according to an embodiment of the present disclosure. [Modes for carrying out the invention]

[0010] The following describes the technical concepts in the embodiments of this disclosure clearly and completely, with reference to the drawings in the embodiments of this disclosure. Clearly, the embodiments described are some, but not all, embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure, without any creative effort on their part, are all within the scope of this disclosure.

[0011] The flowcharts shown in the diagrams are for illustrative purposes only and do not necessarily include all content and operations / steps, nor are they performed in the order they are described. For example, certain operations / steps may be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0012] It should be understood that the terminology used in this disclosure is solely for the purpose of describing specific embodiments and is not intended to limit this disclosure. For example, as used in this disclosure and in the claims, unless the context explicitly indicates otherwise, the singular forms “one,” “one,” and “the said” are intended to include the plural form.

[0013] As 5G systems are deployed and their applications expand, Redcap (Reduced Capability) terminals are emerging to better meet the specific needs of terminal IoT applications such as industrial wireless sensors, video surveillance, and wearable devices, including reduced complexity and cost, smaller dimensions, and lower energy consumption. For each Redcap terminal within a service cell, if each Redcap terminal needs to measure common signals and common channels, they must switch from a low-bandwidth dedicated BWP (Bandwidth Part) to a BWP containing CD-SSB (Cell Defining-Synchronization Signal Block), temporarily move the corresponding task to the CD-SSB-containing BWP, and then switch back to the low-bandwidth dedicated BWP after the measurement is complete. This frequent switching of BWPs leads to problems such as high power consumption for Redcap terminals, frequent interruptions to operations, and potential congestion of the CD-SSB-containing BWP.

[0014] For example, as shown in Figures 1 and 2, let's consider only two Redcap terminals, namely Redcap UE (User Equipment) 1 and Redcap UE2. In Figure 1, at time T1, terminal 1 (Redcap UE1) switches from a small bandwidth 1 (BWP1) to bandwidth 0 (BWP0) including the cell-defined signal block (CD-SSB) to perform measurements and obtain information such as the corresponding signal strength. Terminal 2 (Redcap UE2) switches from a small bandwidth 2 (BWP2) to bandwidth 0 (BWP0) including the CD-SSB to perform measurements and obtain information such as the corresponding signal strength. After the measurements are completed, as shown in Figure 2, at time T2, terminal 1 (Redcap UE1) switches from bandwidth 0 (BWP0) to a small bandwidth 1 (BWP1), and terminal 2 (Redcap UE2) switches from bandwidth 0 (BWP0) to a small bandwidth 2 (BWP2).

[0015] Thus, there is a problem of frequently switching BWP, which is likely to cause temporary interruption of services and congestion of BWP0.

[0016] To solve the above problems, embodiments of the present disclosure provide a method for measuring a common signal of a terminal, a terminal, and a storage medium, which solve the problems that frequent switching of BWP results in high power consumption of the terminal, is likely to cause temporary interruption of services, and may also cause congestion of BWP including CD-SSB.

[0017] Hereinafter, some embodiments of the present disclosure will be described in detail with reference to the drawings. Unless there is a contradiction, the following embodiments and the features in the embodiments can be combined with each other.

[0018] Referring to FIG. 3, FIG. 3 is a flow schematic diagram of a method for measuring a common signal of a terminal according to an embodiment of the present disclosure.

[0019] As shown in FIG. 3, the method for measuring the common signal of the terminal may include step S101 and S102, or step S101 and S103, or steps S101 to S103.

[0020] S101: Determine whether the terminal is a master terminal in the terminal cluster to which the current terminal belongs. If so, execute step S102; otherwise, execute step S103.

[0021] S102: Switch to a carrier bandwidth including common broadcast information to measure a common signal, obtain first common signal data, and transmit the first common signal data to a slave terminal in the terminal cluster.

[0022] S103: Obtain first common signal data measured by a master terminal, and obtain second common signal data corresponding to the current terminal based on the first common signal data.

[0023] Here, the terminal includes but is not limited to a Redcap terminal. Exemplarily, all terminals in each terminal cluster are located within the same service cell. Based on the service cell corresponding to each terminal, each terminal is classified into a cluster, and it is determined that each terminal located within the same service cell belongs to the same terminal cluster.

[0024] For example, assume there are four terminals connected to the same local area network. The terminal IDs of the four terminals are Terminal 1, Terminal 2, Terminal 3, and Terminal 4 respectively. These four terminals are located within two service cells, and the cell IDs of the two service cells are Cell 1 and Cell 2 respectively. Here, Terminal 1, Terminal 2, and Terminal 3 are located within Cell 1, and Terminal 4 is located within Cell 2. Then, Terminal 1, Terminal 2, and Terminal 3 form one terminal cluster, and Terminal 4 forms another terminal cluster.

[0025] During the normal operation process, within the same terminal cluster, only one terminal is regarded as the master terminal at the same time, and all other terminals are regarded as sub-terminals. The determination of the master terminal may be realized in various ways such as adopting rotation or applying for arbitration, and the present disclosure does not specifically limit this.

[0026] It should be noted that the measurement method of the common signal may be operated on the master terminal or on the sub-terminal. In one exemplary embodiment, when it is known that the current terminal itself is the master terminal, the measurement method of the common signal of the terminal may include, when it is necessary to measure the common signal, switching the master terminal to the carrier bandwidth including common broadcast information to measure the common signal, obtaining the first common signal data, and transmitting the first common signal data to the sub-terminals in the terminal cluster. In another exemplary embodiment, when it is known that the current terminal itself is a sub-terminal, the measurement method of the common signal of the terminal may further include obtaining the first common signal data measured by the master terminal and obtaining the second common signal data corresponding to the current terminal based on the first common signal data.

[0027] In one exemplary embodiment, before each terminal in the terminal cluster measures the common signal, a calibration misalignment operation may be performed on each terminal to obtain calibration misalignment information between each terminal in the terminal cluster and each other. Exemplarily, the calibration misalignment information includes, but is not limited to, signal intensity calibration difference values.

[0028] In some embodiments, prior to the step of determining whether the current terminal is a master terminal in the terminal cluster to which it currently belongs, the current terminal is switched to a carrier bandwidth containing common broadcast information to measure the common signal, obtain first calibration common signal data, and transmit the first calibration common signal data to each other terminal in the terminal cluster; the current terminal is further switched to a carrier bandwidth containing common broadcast information to measure the common signal, obtain first calibration common signal data, and transmit the first calibration common signal data to each other terminal in the terminal cluster; the current terminal is further switched to a carrier bandwidth containing common broadcast information to measure the common signal, obtain calibration misalignment information between the current terminal and each of the other terminals in the terminal cluster based on the first calibration common signal data and each of the second calibration common signal data.

[0029] For illustrative purposes, the carrier bandwidth containing common broadcast information may be a BWP including CD-SSB, but is not limited to these. Below, the method for measuring the common signal of a terminal in this disclosure will be explained using the example that the carrier bandwidth containing common broadcast information is a BWP including CD-SSB.

[0030] For example, still using terminals 1, 2, 3, and 4 listed above as examples, each terminal is initially switched to BWP including CD-SSB to measure the common signal. Depending on the measurement conditions, terminals with the same measured corresponding cell identification (cell ID) are determined to form a single terminal cluster. For example, terminals 1, 2, and 3 form one terminal cluster, and each terminal acquires its own measured first calibration common signal data, transmits its own measured first calibration common signal data to other terminals in the terminal cluster, and receives second calibration common signal data transmitted from other terminals. Here, the calibration common signal data corresponding to each terminal includes, but is not limited to, common signal intensity values ​​and common channel PDU (Protocol Data Unit) information. In this way, by determining the difference between the first calibration common signal data and each second calibration common signal data, calibration misalignment information between each terminal and other terminals in the terminal cluster is obtained, and the calibration misalignment information between each terminal itself and other terminals in the terminal cluster is stored.

[0031] For example, using terminals 1, 2, 3, and 4 listed above as examples, Table 1 shows the basic measurement status information after switching each of the four terminals to BWP including CD-SSB for the first time and measuring the common signal.

[0032] [Table 1]

[0033] Because the distance between each terminal and the base station is not constant and changes, it is necessary to create a calibration difference value for the signal strength. On the other hand, for all terminals in the same cell, i.e., each terminal in the same terminal cluster, the common channel PDU information is the same, so it is not necessary to create a calibration difference value.

[0034] In some embodiments, after the step of obtaining calibration misalignment information between the current terminal and each other terminal in the terminal cluster, the method includes the step of generating a calibration table for the current terminal based on the calibration misalignment information between the current terminal and each other terminal in the terminal cluster, and the terminal identification information of each other terminal.

[0035] Here, terminal identification information includes, but is not limited to, the terminal ID and terminal IP address. In the calibration table, calibration deviation information with other terminals and terminal identification information of other terminals are associated on a one-to-one basis. For example, the signal strength calibration difference value and terminal identification information are associated on a one-to-one basis.

[0036] For example, still using Table 1 above as an example, calibration deviation information is calculated based on the signal strength values ​​of terminal 1, terminal 2, and terminal 3, and the generated calibration table for terminal 1 is shown in the figure.

[0037] [Table 2]

[0038] Based on the signal strength values ​​of terminal 2, terminal 1, and terminal 3, calibration deviation information was calculated, and the generated calibration table for terminal 2 is shown in Table 3.

[0039] [Table 3]

[0040] Based on the signal strength values ​​of terminal 3, terminal 1, and terminal 2, calibration deviation information was calculated, and the generated calibration table for terminal 3 is shown in Table 4.

[0041] [Table 4]

[0042] Terminal 4 is located in another cell and has no other paired terminals; therefore, it is not classified into a terminal cluster, and the calibration table for Terminal 4 is blank.

[0043] Furthermore, when each terminal in a terminal cluster needs to measure the common signal, the master terminal and sub-terminals use different methods to measure the common signal.

[0044] For example, taking the terminal cluster still including terminals 1, 2, and 3 listed above as an example, if terminal 1 is the master terminal, then terminals 2 and 3 are sub-terminals.

[0045] When one of the terminals needs to measure the common signal, it is first determined whether or not it is currently the master terminal in the terminal cluster to which it belongs. If the terminal is currently the master terminal, it switches to BWP including CD-SSB to perform the measurement and obtains the master terminal's first common signal data. The master terminal then transmits the first common signal data to each sub-terminal in the terminal cluster, one copy at a time.

[0046] For example, each terminal in a terminal cluster establishes a connection with a third party by means of wired, Bluetooth®, or other methods, and the master terminal transmits the first common signal data to each of the other sub-terminals in the terminal cluster by connecting to the third party of the other terminals in the terminal cluster.

[0047] If the terminal is currently a sub-terminal, the sub-terminal acquires the first common signal data from the master terminal and, based on that first common signal data, acquires a second common signal data corresponding to the sub-terminal.

[0048] For example, common signal data corresponding to each terminal in a terminal cluster includes common measurement information and common data information, where common measurement information includes, but is not limited to, common signal intensity values, and common data information includes, but is not limited to, common channel PDU information, etc.

[0049] For example, taking terminal 1 as an example, in this case terminal 1 is the master terminal, and when the master terminal receives a request from a sub-terminal to measure the common channel / common signal, or in this case the master terminal itself has a need to measure the common channel / common signal, it switches to BWP including CD-SSB to measure, and if the measured common signal strength value is -80 and the common channel PDU information is 11 22 33, then it sends the common signal strength value and common channel PDU information to each sub-terminal in the terminal cluster, i.e., to terminals 2 and 3.

[0050] In some embodiments, the step of obtaining a second common signal data corresponding to the current terminal based on the first common signal data includes the steps of differentiating the first common measurement information in the first common signal data and obtaining the second common measurement information in the second common signal data, and determining the first common data information in the first common signal data as the second common data information in the second common signal data.

[0051] As an example, the common signal strength value of the master terminal is differentiated and calculated, the common signal strength value corresponding to the sub-terminal is obtained, and the common channel PDU information of the master terminal is directly determined as the common channel PDU information corresponding to the sub-terminal.

[0052] For example, a differentiation calculation is performed on the common signal strength value corresponding to terminal 1, which is -80, to obtain the common signal strength value corresponding to terminal 2, and the common channel PDU information 11 22 33 corresponding to terminal 1 is determined to be the common channel PDU information corresponding to terminal 2.

[0053] In some embodiments, the step of differentiating the first common measurement information in the first common signal data and obtaining the second common measurement information in the second common signal data includes the step of obtaining calibration deviation information between the current terminal and the master terminal, and the step of adding the calibration deviation information to the first common measurement information and obtaining the second common measurement information.

[0054] As an example, based on the signal strength calibration difference between the current terminal and the master terminal, the signal strength calibration difference is added to the common signal strength value of the master terminal to obtain the common signal strength value of the current terminal.

[0055] In some embodiments, the step of obtaining calibration misalignment information between the current terminal and the master terminal includes querying the calibration table of the current terminal and obtaining calibration misalignment information between the current terminal and the master terminal, wherein the calibration table includes calibration misalignment information between the current terminal and each other terminal in the terminal cluster.

[0056] For example, based on the calibration tables generated for each of the above terminals, the calibration table corresponding to the current terminal is queried, and the signal strength calibration difference value between the current terminal and the master terminal is obtained.

[0057] In some embodiments, the step of querying the calibration table of the current terminal and obtaining calibration misalignment information between the current terminal and the master terminal includes the steps of determining terminal identification information of the master terminal and querying the calibration table based on the terminal identification information and determining the calibration misalignment information associated with the terminal identification information in the calibration table as the calibration misalignment information between the current terminal and the master terminal.

[0058] In each terminal's calibration table, calibration deviation information between the terminal itself and other terminals, and terminal identification information of other terminals are associated on a one-to-one basis. By determining the terminal identification information of the master terminal and querying the calibration table, the calibration deviation information associated with that terminal identification information can be obtained, and this associated calibration deviation information is, in other words, the calibration deviation information between the current terminal and the master terminal.

[0059] For example, if terminal 2 is a sub-terminal, and terminal 2 receives and obtains that the signal strength value measured by terminal 1 (master terminal) is -80, it queries its calibration table and obtains that the signal strength calibration difference value between terminal 2 and terminal 1 is -10, then terminal 2 calculates that the signal strength value at its own location is -90, and then decodes and stores the latest common channel PDU information 11 22 33.

[0060] Terminal 3 is also a sub-terminal. Terminal 3 receives and obtains that the signal strength value measured by Terminal 1 (master terminal) is -80. It queries its calibration table and obtains that the signal strength calibration difference between Terminal 3 and Terminal 1 is -15. In this case, Terminal 3 calculates that the signal strength value at its own location is -95, and then decodes and stores the latest common channel PDU information 11 22 33.

[0061] In this way, the process of sharing common signal data is completed in one step, avoiding the need for terminals 2 and 3 to switch BWPs.

[0062] As shown in Figure 4, the measurement flow for the terminal is as follows: Step 1: Determine whether the current terminal is the master terminal in the terminal cluster. If so, jump to Step 2; otherwise, jump to Step 5.

[0063] Step 2: Switch to BWP including CD-SSB and perform measurement and reading. Step 3: Send the measurement results to other terminals in the terminal cluster.

[0064] Step 4: Once the measurement is complete, switch back to the original BWP. Step 5: Obtain the measurement results from the master terminal.

[0065] Step 6: Based on the measurement results of the master terminal, the calibration deviation information is linked to obtain the measurement results of the current terminal.

[0066] Step 7: Measurement is complete. In this way, each sub-terminal in the terminal cluster avoids frequent BWP switching operations, reducing terminal power consumption and business interruption time, and avoiding BWP congestion, including CD-SSB.

[0067] In the above embodiment, it is determined whether the current terminal is a master terminal in the terminal cluster to which it belongs. If the current terminal is a sub-terminal, first common signal data measured by the master terminal in the terminal cluster is acquired. Based on the first common signal data, second common signal data corresponding to the current terminal is obtained. Therefore, measurements can be taken for sub-terminals in the terminal cluster without switching to a carrier bandwidth containing common broadcast information. This avoids the terminal having to frequently switch carrier bandwidths, reduces terminal power consumption and business interruption time, and avoids congestion in the carrier bandwidth containing common broadcast information.
