Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

In the prior art, the execution process of the repeated data transmission operation is usually: the base station indicates the number of repeated transmissions (the number of repeated transmission indications) (the repeated transmissions indicated by the base station are called nominal repetitions); Start to calculate the number of repeated transmissions; when the calculated number of repeated transmissions reaches the number of repeated transmissions indicated by the base station (the number of repeated transmissions indicated), stop the repeated transmission of data. Or, when the number of repeated transmissions obtained by calculation does not reach the number of repeated transmissions indicated by the base station (the number of repeated transmission indications), the preset stop condition is met, and the repeated data transmission is also stopped (for example, a system error, or the instructed to stop the repeated transmission of data) ).

In practical application scenarios, the number of repeated transmissions is calculated by calculating time slots. Specifically, the timeslots are counted when the repeated data transmission is started, and the number of timeslots passed is the number of times of repeated transmission. However, in the actual scenario of data transmission, time slots include valid time slots (eg, uplink time slots) that can be used for data transmission, and invalid time slots (eg, downlink time slots and special time slots) that cannot be used for data transmission. gap). In this way, if the number of elapsed time slots is used as the number of repeated transmissions, it is equivalent to including the time slots that cannot be used for data transmission into the count, and the actual number of repeated data transmissions performed by the terminal (actual repetitions) is less than nominal repetitions, resulting in the final The coverage enhancement effect is not as expected.

For example, FIG. 1 is a schematic diagram of a time slot of a data transmission application scenario. As shown in Figure 1, each rectangle represents a time slot, the mark D represents the downlink time slot, the mark S represents the special time slot, and the mark U represents the uplink time slot. The uplink time slot is an effective time slot that can perform repeated data transmission. If the base station indicates that the number of repeated transmissions (nominal repetitions) is 8, the data repetition transmission is started at time slot 101, and the data repetition transmission is stopped after 8 time slots (the repetition transmission duration is 110), and the terminal actually performs data repetition transmission. The actual repetition is not 8 after excluding downlink time slots and special time slots, but only 3 times (

uplink time slots

101, 102, 103).

If the base station indicates that the number of repeated transmissions (nominal repetitions) is 16 times, the data repetition transmission is started at time slot 104, and the data repetition transmission is stopped after 16 time slots (the repetition transmission duration is 120), and the terminal actually performs data repetition transmission. After excluding downlink time slots and special time slots, the actual repetition is not 16 times, but only 6 times (

uplink time slots

104, 105, 106, 107, 108, 109).

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

For example, FIG. 2 is a schematic diagram of a time slot of a data transmission application scenario. As shown in Fig. 2, each rectangle represents a time slot, the mark D represents the downlink time slot, the mark S represents the special time slot, and the mark U represents the uplink time slot. The uplink time slot is an effective time slot that can perform repeated data transmission. If the base station indicates that the number of repeated transmissions (nominal repetitions) is 8 times, the data repetition transmission is started in time slot 201, and after 16 time slots (the attenuation coefficient is 0.5, the number of time slots passed by the attenuation coefficient is multiplied by the attenuation coefficient. After excluding the calculated value of the number of repeated transmissions), the repeated transmission of data is stopped (the repeated transmission duration is 210), and the actual number of repeated transmissions of data by the terminal (actual repetition) is 6 times after excluding downlink time slots and special time slots (uplink time slots). 201, 202, 203, 204, 205, 206). Compared with the embodiment shown in FIG. 1, the number of nominal repetitions is 8 and the actual repetition is 3 application scenarios, the coverage enhancement effect is greatly increased.

For example, FIG. 3 is a schematic diagram of a time slot of a data transmission application scenario. As shown in Fig. 3, 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 an effective time slot that can perform repeated data transmission. If the base station indicates that the number of nominal repetitions is 16, the data repeat transmission is started at time slot 301, and after 26 time slots (the attenuation value is 10, the number of time slots passed minus the attenuation value is the value of After excluding the calculated value of the number of repeated transmissions), the repeated transmission of data is stopped (the repeated transmission duration is 310), and the actual number of repeated data transmissions (actual repetition) by the terminal is 9 times after excluding downlink time slots and special time slots (uplink time slots). 301, 302, 303, 304, 305, 306, 307, 308, 309). Compared with the embodiment shown in FIG. 1 , the number of nominal repetitions is 16 and the actual repetition is 6 application scenarios, the coverage enhancement effect is greatly increased.

Further, 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) that have passed through.

For example, FIG. 4 is a schematic diagram of a time slot of a data transmission application scenario. As shown in Fig. 4, each rectangle represents a time slot, the mark D represents the downlink time slot, the mark S represents the special time slot, and the mark U represents the uplink time slot. The uplink time slot is an effective time slot that can perform repeated data transmission. If the base station indicates that the number of repeated transmissions (nominal repetitions) is 8 times, the data repetition transmission is started at time slot 401, and the data repetition transmission is stopped after 8 uplink time slots (the repetition transmission duration is 410), and the terminal actually performs data repetition. The actual repetition of transmission is 8 (

upstream time slots

401, 402, 403, 404, 405, 406, 407, 408).

Further, in an actual application scenario, one of the above-mentioned three calculation modes for the number of repeated transmissions may be preset as the calculation mode for the number of repeated transmissions used in the repeated data transmission operation according to actual requirements. For example, it is enabled or disabled through Radio Resource Control (RRC). Based on the RRC, it is determined which mode of calculating the number of repeated transmissions to adopt.

However, in practical application scenarios, RRC configuration and reconfiguration have a large delay, which cannot cope with rapidly changing channel environment or terminal movement. Therefore, in an 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 repeated transmission method and avoid wasting resources.

Specifically, an embodiment of the present application proposes a coverage enhancement method, and the method is executed by a communication device (eg, a communication base station, or a signal sending node of a subordinate communication base station). Specifically, FIG. 5 is a flowchart of a coverage enhancement method according to an embodiment of the present application. The communication device performs the following steps as shown in Figure 5:

Step 510, obtaining the number of times of repeated transmission instructions;

Step 520: Perform repeated transmission of data based on the number of repeated transmission indications, and during the repeated transmission of data, calculate the number of repeated transmissions, wherein the calculation mode used to calculate the number of repeated transmissions is set according to the calculation mode indication information of the number of repeated transmissions. calculation mode.

Specifically, for example, FIG. 6 shows a flowchart of a coverage enhancement method according to an embodiment of the present application. The communication device performs the following steps as shown in Figure 6:

Step 601, obtaining the indication information of the repeated transmission times calculation mode;

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

Step 610: Acquire the number of repeated transmission indications indicated by the base station;

Step 620, start the repeated transmission of data;

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

Step 640, when the number of repeated transmissions reaches the indicated number of repeated transmissions, stop the repeated transmission of data.

Specifically, the calculation mode for calculating the number of repeated transmissions includes:

The first calculation mode, in the first calculation mode, the number of repeated transmissions is the number of valid transmission time slots after the repeated data transmission is started;

The second calculation mode, in the second calculation mode, the number of repeated transmissions is the number of transmission time slots after the repeated data transmission is started;

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 repeated data transmission is started.

In an actual application scenario, the above three calculation modes may be used as alternative modes according to actual requirements, and one calculation mode may be selected from the above three calculation modes according to the calculation mode indication information of the number of repeated transmissions. Any two of the above three calculation modes may also be used as alternative modes, and one calculation mode may be selected from the two alternative calculation modes according to the calculation mode indication information of the number of repeated transmissions.

Further, in the actual application scenario, the indication information of the calculation mode of the number of repeated transmissions can be obtained in the communication initialization stage to determine the calculation mode of the number of repeated transmissions, and the calculation mode is used in the subsequent communication process until the end of a communication cycle. . It is also possible to obtain the calculation mode indication information of the number of repeated transmissions to determine the calculation mode of the number of repeated transmissions to be used for the current repeated data transmission before each repeated data transmission is performed.

Further, in an embodiment of the present application, the indication information of the calculation mode for the number of repeated transmissions is information carried in a joint coding manner.

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

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

IndexIndex	K0K0	TypeType	SLIVSLIV
00	00	A/BA/B	XXXXXX
11	11	AA	5656
22	44	A/BA/B		XXXXXX
33	66	A/BA/B	XXXXXX
……	……	……	……
1515	3232	A/BA/B	XXXXXX

Table 1

The first column is the sequence number, which is the index.

The second column is the K0/K2 value, K0/K2 is the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Share Channel (PDSCH)/Uplink Physical Shared Channel (Physical Uplink Shared Channel, PUSCH) ) Slot interval between PUSCHs. For example, when K0 is 1, the PDCCH is in time slot n, and its corresponding PDSCH is in time slot n+1.

The third column is the mapping type, A represents slot-based mapping (meaning that a slot is a scheduling unit, and the PDCCH is always located in the first 1, 2 or 3 symbols of a slot), and B represents mini-based mapping The mapping of time slots (mini-slot) (counting symbols is a scheduling unit, according to the number of symbols in a mini time slot, the starting position of PDCCH is not limited to the first symbol in the time slot, for example, the length of the mini time slot is 7 symbols, then the PDCCH can be located in the first symbol or in the 8th symbol).

The fourth column is a start and length indication value (SLIV), and the value of this column indicates the position of the start symbol of the PDSCH and the length of the continuation symbol of the PDSCH.

For example, FIG. 7 is a schematic structural diagram of a PDCCH and a PDSCH in an application scenario. According to the values shown in the second row in Table 1 (Index=1, K0=1, type=A, SLIV=56), as shown in Figure 7, the PDCCH is located in the first 2 symbol bits of slot n (Slot n). , PDSCH is located in the first 5 symbol bits of slot n+1 (Slot n+1).

In an embodiment of the present application, the TDRA domain is used to carry the repeated transmission times calculation mode indication information.

Specifically, the TDRA field is associated with the indication information of the repeated transmission times calculation mode (equivalent to adding one column to the TDRA table). When the TDRA access (entries) is configured by the upper layer, the index of the TDRA table is associated with the calculation mode of the number of repeated transmissions. In this way, the DCI indicates a certain TDRA index value while indicating the repeated transmission calculation mode.

For example, as shown in Table 2:

Table 2

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.

In another embodiment of the present application, a new field is introduced into the DCI: the repeated transmission times indication field. The repeated transmission times calculation mode indication information is carried by the repeated transmission times indication field. Specifically, the indication information of the repeated transmission times calculation mode is carried by the repeated transmission times indication field, and the repeated transmission times indication field is used to indicate the repeated transmission indication times.

The indication table of repeated transmission times is shown in Table 3:

table 3

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

Further, in the 1990s, an improvement in a technology can be clearly differentiated between improvements in hardware (for example, improvements to circuit structures such as diodes, transistors, switches, etc.) or improvements in software (improvements in method procedures). ). However, with the development of technology, the improvement of many methods and processes today can be regarded as a direct improvement of the hardware circuit structure. Designers almost get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by hardware entity modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is an integrated circuit whose logical function is determined by an accessor programming the device. It is programmed by the designer to "integrate" a digital device on a PLD, without the need for a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, today, instead of making integrated circuit chips by hand, this kind of programming is also mostly implemented using "logic compiler" software, which is similar to the software compiler used in program development and writing, and needs to be compiled before compiling. The original code of the device must also be written in a specific programming language, which is called Hardware Description Language (HDL), and 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., currently the most commonly used The ones are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that a hardware circuit for implementing the logic method process can be easily obtained by simply programming the method process in the above-mentioned several hardware description languages and programming it into the integrated circuit.

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

The repeated transmission times acquisition module, which is used to acquire the repeated transmission times;

Repeat transmission control module, which is used to:

The repeated transmission of data is started, and during the repeated transmission of data, the number of repeated transmissions is calculated, wherein the calculation mode for calculating the number of repeated transmissions is a calculation mode set according to the calculation mode indication information of the number of repeated transmissions.

For example, in one embodiment, the repeat transmission control module is used to:

Initiate data repeat transmission;

Calculate the number of repeated transmissions, wherein the calculation mode used to calculate the number of repeated transmissions is a calculation mode set according to the calculation mode indication information of the number of repeated transmissions;

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