[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0034] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0035] In the prior art, the execution flow of the data repetition operation is generally as follows: the base station indicates the number of repetitions (the number of repetitions indicated) (the repetitions indicated by the base station are called nominal repetitions); the data repetition is started and the number of repetitions is calculated; when the calculated number of repetitions reaches the number of repetitions indicated by the base station (the number of repetitions indicated), the data repetition is stopped. Alternatively, when the calculated number of repetitions does not reach the number of repetitions indicated by the base station (the number of repetitions indicated), the preset stop condition is met and the data repetition is also stopped (for example, a system error, or the data repetition is instructed to stop).

[0036] In actual application scenarios, the number of repeated transmissions is calculated by counting time slots. Specifically, the time slots are counted while starting the data retransmission, and the number of time slots that have passed is the number of repeated transmissions. However, in actual data transmission scenarios, time slots include valid time slots that can be used to transmit data (for example, uplink time slots), and invalid time slots that cannot be used for data transmission (for example, downlink time slots and special time slots). In this way, if the number of repeated transmissions is taken as the number of passed time slots, it is equivalent to counting the time slots that cannot be used for data transmission. The actual number of data repetitions performed by the terminal (actual repetitions) is less than the nominal repetitions, resulting in the final coverage enhancement effect failing to meet expectations.

[0037] For example, Figure 1 FIG. 1 is a schematic diagram of a time slot in a data transmission application scenario. Figure 1 As shown, each rectangle represents a time slot, the mark D represents a downlink time slot, the mark S represents a special time slot, and the mark U represents an uplink time slot. The uplink time slot is a valid time slot for data repetition. If the base station indicates that the number of repetitions (nominal repetitions) is 8 times, the data repetition is started at time slot 101, and the data repetition is stopped after 8 time slots (the repetition duration phase is 110), the actual number of data repetitions performed by the terminal (actual repetition) is not 8 times after excluding the downlink time slot and the special time slot, but only 3 times (uplink time slots 101, 102, 103).

[0038] If the base station indicates that the number of repetitions (nominal repetitions) is 16 times, data repetition is started at time slot 104, and data repetition is stopped after 16 time slots (the repetition duration phase is 120), the actual number of data repetitions performed by the terminal (actual repetition) is not 16 after excluding downlink time slots and special time slots, but only 6 times (uplink time slots 104, 105, 106, 107, 108, 109).

[0039] In view of the above situation, in one embodiment of the present application, a feasible solution is to increase the count amount. For example, if the base station indicates that the number of repeated transmissions (nominal repetitions) is N times, when calculating the number of data repeated transmissions, the number of time slots passed is still calculated, but the number of repeated transmissions (nominal repetitions) N indicated by the base station is not used as the median of the count, but the value of N is increased according to the preset increment strategy to obtain M (for example, M=2N, or M=N+a (a is a preset constant)), and M is used as the median of the count. It can also be said that the number of time slots passed is attenuated according to the preset attenuation strategy, and the value obtained is the number of repeated transmissions. For example, the number of time slots passed is multiplied by the preset attenuation coefficient, or the number of time slots passed is subtracted from the preset attenuation value.

[0040] For example, Figure 2 FIG. 1 is a schematic diagram of a time slot in a data transmission application scenario. Figure 2 As shown, each rectangle represents a time slot, the mark D represents a downlink time slot, the mark S represents a special time slot, and the mark U represents an uplink time slot. The uplink time slot is a valid time slot in which data can be repeatedly transmitted. If the base station indicates that the number of repetitions (nominal repetitions) is 8 times, the data repetition is started at time slot 201, and after 16 time slots (the attenuation coefficient is 0.5, and the value after the number of time slots passed multiplied by the attenuation coefficient is the calculated value of the number of repetitions) the data repetition is stopped (the repetition duration phase is 210), and the actual number of data repetitions performed by the terminal (actual repetition) is 6 times (uplink time slots 201, 202, 203, 204, 205, 206) after excluding the downlink time slots and special time slots. Compared to Figure 1 In the illustrated embodiment, in the application scenario where the number of nominal repetitions is 8 and the number of actual repetitions is 3, the coverage enhancement effect is greatly increased.

[0041] For example, Figure 3 FIG. 1 is a schematic diagram of a time slot in a data transmission application scenario. Figure 3As shown, each rectangle represents a time slot, the mark D represents a downlink time slot, the mark S represents a special time slot, and the mark U represents an uplink time slot. The uplink time slot is a valid time slot in which data can be repeatedly transmitted. If the base station indicates that the number of repetitions (nominal repetitions) is 16 times, the data repetition is started at time slot 301, and after 26 time slots (the attenuation value is 10, and the value obtained by subtracting the attenuation value from the number of time slots passed is the calculated value of the number of repetitions), the data repetition is stopped (the repetition duration phase is 310). The actual number of data repetitions performed by the terminal (actual repetition) is 9 times (uplink time slots 301, 302, 303, 304, 305, 306, 307, 308, 309) after excluding the downlink time slots and special time slots. Compared to Figure 1 In the illustrated embodiment, in the application scenario where the number of nominal repetitions is 16 and the number of actual repetitions is 6, the coverage enhancement effect is greatly increased.

[0042] Furthermore, in an embodiment of the present application, another feasible solution is to calculate the number of repeated transmissions by counting the valid transmission time slots (time slots that can be used for repeated data transmission).

[0043] For example, Figure 4 FIG. 1 is a schematic diagram of a time slot in a data transmission application scenario. Figure 4 As shown, each rectangle represents a time slot, the mark D represents a downlink time slot, the mark S represents a special time slot, and the mark U represents an uplink time slot. The uplink time slot is a valid time slot in which data can be repeatedly transmitted. If the base station indicates that the number of repetitions (nominal repetitions) is 8 times, the data repetition is started at time slot 401, and the data repetition is stopped after 8 uplink time slots (the repetition duration phase is 410), and the actual number of data repetitions performed by the terminal (actual repetition) is 8 times (uplink time slots 401, 402, 403, 404, 405, 406, 407, 408).

[0044] Further, in actual application scenarios, one of the above three repetition transmission count calculation modes can be preset as the repetition transmission count calculation mode used when performing data repetition transmission operations according to actual needs. For example, it can be enabled or disabled through Radio Resource Control (RRC). Which repetition transmission count calculation mode to use is determined based on RRC.

[0045] However, in actual application scenarios, RRC configuration and reconfiguration have a large delay, which cannot cope with the rapidly changing channel environment or terminal movement. Therefore, in one embodiment of the present application, dynamic signaling is used to indicate the calculation mode of the number of repeated transmissions, so as to quickly adjust the method of repeated transmissions to avoid resource waste.

[0046] Specifically, an embodiment of the present application provides a coverage enhancement method, which is performed by a communication device (eg, a communication base station, or a signal sending node subordinate to the communication base station). Specifically, Figure 5 FIG. 1 is a flow chart of a coverage enhancement method according to an embodiment of the present application. The communication device executes the following Figure 5 The following steps are shown:

[0047] Step 510, obtaining the number of repeated transmission indications;

[0048] Step 520, performing data retransmission based on the retransmission indication number, and calculating the retransmission number during the data retransmission, wherein the calculation mode used to calculate the retransmission number is the calculation mode set according to the retransmission number calculation mode indication information.

[0049] Specifically, for example, Figure 6 FIG. 1 is a flow chart of a coverage enhancement method according to an embodiment of the present application. The communication device executes the following Figure 6 The following steps are shown:

[0050] Step 601, obtaining repeated transmission times calculation mode indication information;

[0051] Step 602, setting a calculation mode for calculating the number of repeated transmissions according to the repeated transmission number calculation mode indication information;

[0052] Step 610, obtaining the number of repeated transmission indications indicated by the base station;

[0053] Step 620, start data retransmission;

[0054] Step 630, calculating the number of repeated transmissions, wherein the calculation mode used to calculate the number of repeated transmissions is the calculation mode set according to the repeated transmission number calculation mode indication information;

[0055] Step 640: When the number of repeated transmissions reaches the number of repeated transmission indications, stop the repeated transmission of data.

[0056] According to the method of the embodiment of the present application, the repeated transmission calculation mode can be dynamically indicated so that the data repeated transmission operation can achieve the expected coverage enhancement effect and achieve a balance between latency and resource consumption.

[0057] Specifically, the calculation modes for calculating the number of repeated transmissions include:

[0058] A first calculation mode, in which the number of repeated transmissions is the number of valid transmission time slots after the repeated transmission of data is started;

[0059] A second calculation mode, in which the number of repeated transmissions is the number of transmission time slots after the data repeated transmission is started;

[0060] The third calculation mode, in the third calculation mode, the number of repeated transmissions is a value obtained after the number of transmission time slots is attenuated according to a preset attenuation strategy after the data repeated transmission is started.

[0061] In actual application scenarios, the above three calculation modes can be used as alternative modes according to actual needs, and one calculation mode can be selected from the above three calculation modes according to the repeated transmission number calculation mode indication information. Any two of the above three calculation modes can also be used as alternative modes, and one calculation mode can be selected from the two alternative calculation modes according to the repeated transmission number calculation mode indication information.

[0062] Furthermore, in actual application scenarios, the repetition transmission count calculation mode indication information can be obtained in the communication initialization phase to determine the repetition transmission count calculation mode, and the calculation mode can be used in subsequent communication processes until a communication cycle ends. The repetition transmission count calculation mode indication information can also be obtained before each data repetition transmission to determine the repetition transmission count calculation mode to be used for the current data repetition transmission.

[0063] Furthermore, in an embodiment of the present application, the repetition transmission times calculation mode indication information is information carried using a joint coding method.

[0064] Specifically, the time domain resource allocation information (TDRA) field in the downlink control information (DCL) is used to indicate the time domain scheduling resource position.

[0065] The TDRA table is an indicator table with a maximum of 16 rows, as shown in Table 1.

[0066] Index K0 Type SLIV 0 0 A / B XXX 1 1 A 56 2 4 A / B XXX 3 6 A / B XXX … … … … 15 32 A / B XXX

[0067] Table 1

[0068] The first column is the serial number, i.e. index.

[0069] The second column is the K0 / K2 value, K0 / K2 is the time slot interval between the physical downlink control channel (PDCCH) and the physical downlink shared channel (PDSCH) / physical uplink shared channel (PUSCH). For example, when K0 is 1, the PDCCH is in time slot n, and its corresponding PDSCH is in time slot n+1.

[0070] The third column is the mapping type. A represents time slot-based mapping (referring to a time slot as a scheduling unit, and PDCCH is always located in the first 1, 2 or 3 symbols of a time slot), and B represents mini-slot-based mapping (referring to a number of symbols as a scheduling unit. According to the number of symbols in a mini-slot, the starting position of PDCCH is not limited to the first symbol in the time slot. For example, if the mini-slot length is 7 symbols, then PDCCH can be located at the first symbol or the 8th symbol).

[0071] The fourth column is the start and length indication value (SLIV), and the value of this column indicates the start symbol position of the PDSCH and the continuous symbol length of the PDSCH.

[0072] For example, Figure 7 The structure diagram of PDCCH and PDSCH in an application scenario is shown in FIG. According to the values ​​shown in the second row of Table 1 (Index=1, K0=1, type=A, SLIV=56), Figure 7 As shown, the PDCCH is located at the first 2 symbol bits of time slot n (Slot n), and the PDSCH is located at the first 5 symbol bits of time slot n+1 (Slot n+1).

[0073] In one embodiment of the present application, the TDRA field is used to carry the repeated transmission times calculation mode indication information.

[0074] Specifically, the TDRA field is associated with the repeated transmission count calculation mode indication information (equivalent to adding a column to the TDRA table). When the high-level layer configures TDRA entries, the index of the TDRA table is associated with the repeated transmission count calculation mode. In this way, the DCI indicates a certain TDRA index value and the repeated transmission calculation mode at the same time.

[0075] For example, as shown in Table 2:

[0076]

[0077] Table 2

[0078] In the Repetition Calculate column in Table 1, A is the first calculation mode, B is the second calculation mode, and C is the third calculation mode.

[0079] In another embodiment of the present application, a new field is introduced in the DCI: a repetition number indication field. The repetition number indication field carries repetition number calculation mode indication information. Specifically, the repetition number calculation mode indication information is carried by the repetition number indication field, and the repetition number indication field is used to indicate the number of repetition indications.

[0080] The repeated transmission times indication table is shown in Table 3:

[0081]

[0082] Table 3

[0083] In Table 3, the first column is the serial number, i.e., index; the second column (Repetition) is the number of repeated transmission indications indicated by the base station; in the third column, repetition calculation (Repetition Calculate), A is the first calculation mode, and B is the second calculation mode (in this embodiment, only the first calculation mode and the second calculation mode are listed as alternative modes).

[0084] Furthermore, in the 1990s, it was very clear whether the improvement of a technology was a hardware improvement (for example, an improvement to the circuit structure of a diode, transistor, switch, etc.) or a software improvement (an improvement to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the access party programming the device. Designers can "integrate" a digital device on a PLD by programming themselves, without having to ask a chip manufacturer to design and make a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0085] Therefore, according to the method of the present application, the present application also proposes a coverage enhancement device, which can be built in a communication device. The device includes:

[0086] A repeated transmission number acquisition module, which is used to obtain the repeated transmission number;

[0087] Repeat transmission control module, which is used to:

[0088] Initiate data repetitive transmission, and during the data repetitive transmission, calculate the number of repetitive transmissions, wherein the calculation mode used to calculate the number of repetitive transmissions is the calculation mode set according to the repetitive transmission number calculation mode indication information.

[0089] For example, in one embodiment, the repetitive transmission control module is used to:

[0090] Start repeated data transmission;

[0091] Calculating the number of repeated transmissions, wherein the calculation mode used to calculate the number of repeated transmissions is the calculation mode set according to the repeated transmission number calculation mode indication information;

[0092] When the number of repeated transmissions reaches the repeated transmission number, the data repeated transmission is stopped.

[0093] In the description of the embodiments of the present application, for the convenience of description, the device is described by dividing it into various modules according to its functions. The division of each module is merely a division of logical functions. When implementing the embodiments of the present application, the functions of each module can be implemented in the same or one or more software and / or hardware.

[0094] Specifically, the device proposed in the embodiment of the present application can be fully or partially integrated into a physical entity during actual implementation, or it can be physically separated. And these modules can all be implemented in the form of software calling through processing elements; they can also be all implemented in the form of hardware; some modules can also be implemented in the form of software calling through processing elements, and some modules can be implemented in the form of hardware. For example, the detection module can be a separately established processing element, or it can be integrated in a chip of an electronic device. The implementation of other modules is similar. In addition, all or part of these modules can be integrated together, or they can be implemented independently. In the implementation process, each step of the above method or each of the above modules can be completed by an integrated logic circuit of hardware in a processor element or instructions in the form of software.

[0095] For example, the above modules may be one or more integrated circuits configured to implement the above methods, such as one or more application specific integrated circuits (ASIC), or one or more digital signal processors (DSP), or one or more field programmable gate arrays (FPGA), etc. For another example, these modules may be integrated together and implemented in the form of a system-on-a-chip (SOC).
