technical field

The present application relates to the field of communication, and more particularly, to a wireless communication method and communication device.

Background technique

With the continuous development of wireless communication technology, mobile communication has been widely used in various fields. For example, the Internet of Things, as an important part of future communication networks, is mainly used in intelligent meter reading, medical monitoring and monitoring, industrial monitoring and monitoring, Internet of Vehicles, intelligent community and wearables, etc. Different application scenarios have different requirements for communication delay, rate, and reliability. Control information is used as data scheduling information. First, the correct transmission of control information is the premise of correct data transmission. Second, control information needs to have sufficient indication flexibility to meet the needs of communication services in different application scenarios. For example, in a high-rate requirement scenario, the control information may indicate a multiple-input-multiple-output transmission method or a high-modulation-order modulation method. For another example, in a high-reliability requirement scenario, the control information may indicate repeated data transmission to ensure Reliability of data transmission. At present, in the narrowband internet of things (NB-IoT), the modulation method supported by downlink is quadrature phase shift keying (QPSK), and the modulation method supported by uplink is binary phase shift. Keying (binary phase shift keying, BPSK) and QPSK, can support low-speed IoT services. In NB-IoT R17, it is considered to introduce high-order modulation, such as 16 quadrature amplitude modulation (16 quadrature amplitude modulation, 16QAM), in order to improve the data transmission rate and support higher-speed Internet of Things services. How the downlink control information indicates the scheduling of the high-order modulation and how to improve the flexibility of the control information indication under the premise of ensuring the reliability of the control information transmission are the research hotspots of those skilled in the art.

With the expansion of application scenarios, the communication requirements are correspondingly increasing. For example, IoT application scenarios are diverse, including from outdoor to indoor, from above ground to underground, which puts forward higher requirements for IoT design:

Coverage enhancement: Many IoT terminals are located in environments with poor coverage, such as electric meters and water meters, and are usually installed indoors or even basements where wireless network signals are poor. Therefore, coverage enhancement technology is required to solve the communication quality problem under poor coverage;

Huge number of terminals: The number of IoT devices is far greater than the number of devices that communicate with people;

Low service rate requirements and insensitive to latency: The data packets transmitted by IoT devices are generally small and insensitive to latency;

Extremely low cost: Many IoT applications require very low end-device costs for large-scale deployment;

Low power consumption: In most cases, IoT devices are powered by batteries and are required to be able to be used for more than ten years without battery replacement, which requires IoT devices to operate with extremely low power consumption.

In order to meet these higher demands, the 3rd generation partnership project (3GPP) of the mobile communications standardization organization adopted a new research topic at the GERAN#62 meeting to study the support of extremely low complexity in cellular networks. The method of the Internet of Things with high degree and low cost, and the project was established as the subject of NB-IoT at the RAN#69 meeting.

Specifically, it is necessary to enhance the design of each channel and signal on the basis of the existing communication mode to meet higher demands. For example, currently, the modulation methods supported by NB-IoT downlink are quadrature phase shift keying (QPSK), and the modulation methods supported by uplink are binary phase shift keying (BPSK) and QPSK. It can support low-speed IoT services. However, in order to improve the data transmission rate, the 17th version of NB-IoT considers introducing higher-order modulation methods, such as 16 quadrature amplitude modulation (16 quadrature amplitude modulation, 16QAM), 64QAM, etc., to support higher-speed IoT services . This requires design enhancements to downlink control information (DCI) to support higher-order modulations.

In NB-IoT, uplink data scheduling information is indicated by DCI of format (format) No. Table 1 shows the indication fields (or called fields) and the number of bits in DCI format No. It includes a 4-bit modulation and coding scheme (modulation and coding scheme, MCS) field, which is used to indicate a modulation order and a transport block size (transport block size, TBS) index value. Specifically, when the subcarrier indication field indicates scheduling of 1 subcarrier, the MCS field indicates the modulation order and TBS index value corresponding to the index value by indicating an index value in Table 2. Wherein TBS index value corresponds to Table 3, the TBS index value I _RU binding domain may determine a resource allocation indicated in Table 3 in a TBS. When the subcarrier indication field indicates that 3, 6 or 12 subcarriers are scheduled, the MCS index value indicated by the MCS field is equal to the TBS index value, and the modulation order is 2, as shown in Table 5 for example.

Similarly, the downlink data scheduling information in NB-IoT is indicated by the DCI of format N1, and the respective indication fields and bits in the DCI format N1 are shown in Table 4. It includes a 4-bit MCS field. The MCS field indicates the modulation order corresponding to the index value and the TBS index value by indicating an index value in Table 5.

Table 6

In order to enable DCI format N0 or DCI format N1 to indicate a higher-order modulation mode, the following modes 1 to 4 can be used to design and enhance the DCI. It should be noted that the following description only takes increasing the range of the modulation order indicated by the DCI as an example, and the method provided in this embodiment of the present application can also be applied to enhance other scheduling information or indication information, which is not limited in the present application.

method one

An indication field is added to the DCI, and the indication field is used to indicate the index table corresponding to the MCS field. For example, a 1-bit indication field is added to the DCI. When the 1-bit indicates "0", it indicates that the index table corresponding to the MCS field is the index table A, that is, when the 1-bit indicates "0", it indicates that the MCS field The indicated index value is the index value in index table A, for example, the index table A may be table 2 or table 5 in the prior art. When the 1 bit indicates "1", it indicates that the index table corresponding to the MCS field is the index table B, that is, when the 1 bit indicates "0", it indicates that the index value indicated by the MCS field is the index in the index table B value, the modulation order in index table B is different from the modulation order in index table A. For example, the index table B may include 16QAM, that is, a modulation mode with a modulation order of 4, and the index table B may be as shown in Table 7, but the present application is not limited thereto. In the first way, the index table A and the index table B can also be different parts of the index table C. The first part is the index table A, and the second part is the index table B. When the 1 bit indicates "0", the MCS field indicates the The index value corresponding to the first part, when the 1 bit indicates "1", the MCS field indicates the index value corresponding to the second part, and the present application is not limited to this.

Table 7 is an example of supporting index table B. Optionally, index table B may correspond to a deployment mode.

For example, NB-IoT includes three deployment modes: Guard-band, Stand-alone, and In-band. When the DCI is the DCI Format N1 for scheduling downlink data, when the deployment mode is Guard-band or Stand-alone, the index table B can be as shown in Table 7(a); when the deployment mode is In-band, The index table B may be as shown in Table 7(b), but the present application is not limited thereto.

Method 2

Increase the number of bits in the MCS field in the DCI to increase the indication range of the MCS field. For example, the MCS field is increased by 1 bit, that is, a total of 5 bits in the MCS field indicate the modulation order and the TBS index. The original 4-bit MSC field can indicate 16 modulation and coding modes, that is, the combination of 16 modulation orders and TBS index values, and the 5-bit MCS field after adding 1 bit can indicate 32 modulation and coding modes. For example, the index table corresponding to the MCS domain may be as shown in Table 8, including 23 optional modulation and coding modes, but the present application is not limited to this.

Table 8 is an example of the index table corresponding to the MCS domain, and the index table corresponding to the MCS domain may correspond to the deployment mode.

For example, NB-IoT includes three deployment modes: Guard-band, Stand-alone, and In-band. When the format of the DCI is DCI Format N1 for scheduling downlink data, when the deployment mode is Guard-band or Stand-alone, the index table corresponding to the MCS field in the DCI Format N1 can be as shown in Table 8(a). When the deployment mode is In-band, the index table corresponding to the MCS field in the DCI Format N1 can be as shown in Table 8(b).

When the format of the DCI is the DCI Format N0 for scheduling uplink data, a more specific format of the index table corresponding to the MCS field in the DCI Format N0 can be as shown in Table 8(c).

In addition, as higher modulation orders are supported, a variety of optional TBSs can be added to the TBS index table accordingly. For example, TBS index values 14 to 21 can be added to the uplink TBS index table, and the corresponding TBS values can be as shown in the table 9, but this application does not limit it. For another example, TBS index values 14 to 23 may be added to the downlink TBS index table, and the corresponding TBS values may be as shown in Table 10, but this application does not limit this.

way three

Keep the 4-bit MCS field in the DCI, and adjust the content in the index table corresponding to the MCS field. That is to say, adjust the modulation and coding scheme corresponding to the index value indicated by the MSC field, so that the index values 0 to 15 indicated by the 4 bits include the modulation scheme corresponding to higher-order modulation, and indicate the corresponding TBS index, for example, it can be For an index value in Table 8, the index table corresponding to the MCS domain may be as shown in Table 11.

way four

Reallocate 4 bits of MCS field in DCI with N bits of another field, for example, reassign 4 bits of MCS field in DCI and 4 bits of repetition times field indicating the number of data repetitions in DCI, a total of 8 bits are reallocated . For example, the 8 bits may include a 5-bit MCS field and a 3-bit repetition count field. For example, the 5-bit MCS field may indicate the index value in the index table as shown in Table 8, but the present application is not limited thereto. The 3-bit repetition times may indicate a value of 8 repetitions, for example, 8 repetitions may be selected from the 16 repetitions values indicated by the original 4-bit repetitions field to form an index table. It is also possible that some or all of the values of the 8 repetition times are the values of the redefined repetition times, which is not limited in this application.

According to the above method, the control information can indicate more value ranges of one scheduling information. For example, the MCS field in the DCI can indicate BPSK and QPSK in the prior art, and the MCS field in the DCI can also indicate To higher-order modulation methods, such as 16QAM or 64QAM, etc.

The embodiments of the present application also provide the following design methods of control information. Based on the above design manners 1 to 4, it is possible to avoid increasing the control information overhead and ensure the flexibility of the indication of the existing control information on the basis that the control information indicates more value ranges of the scheduling information.

way five

The DCI for scheduling the first data (that is, an example of the first control information) includes a first field and a second field, the first field includes M bits, and the second field includes K bits, as shown in FIG. 2 . Wherein, M and K are integers greater than or equal to 1. as well as,

When the first field indicates the first state value, the first field is used to indicate the first scheduling information of the first data, and the second field is used to indicate the second scheduling information of the first data and/or the DCI the number of repetitions;

When N bits in the first field indicate a second state value, at least one bit in the second field and/or bits other than the N bits in the first field are used to indicate the first scheduling Information, N is an integer greater than 1 and less than or equal to M.

In one embodiment, the first scheduling information is MCS. When the first field indicates the first state value, the first field is used to indicate the first MCS; when the N bits in the first field indicate the second state value, at least one bit in the second field and /or bits other than the N bits in the first field indicate the second MCS. The modulation orders corresponding to the first MCS and the second MCS are different.

For example, the first field includes _{4 bits a 1} , a ₂ , a ₃ , and a ₄ as described in FIG. 3 , and the first state value may be one of the index values 0000 to 1101 in Table 5. That is to say, when the 4 bits of the first field indicate a value from 0000 to 1101 (the value is the first state value), the first field is used to indicate that the first state value in Table 5 corresponds to the first state value. The modulation method (ie QPSK) and TBS index value. When N bits in the first field indicate the second state value, for example, the N bits may be the first 3 bits a ₁ , a ₂ , and a ₃ in the first field, and when the 3 bits indicate 111, Alternatively, the N bits may be _{a total of 4 bits in the first field a 1} , a ₂ , a ₃ , and a ₄ , when the 4 bits indicate 1110 or 1111, the N bits in the first field are divided in the DCI The other L bits are used to indicate the combination of a higher modulation order such as 16QAM, 64QAM, and the TBS index value. That is to say, when the first field does not indicate a value from 0000 to 1101, the L bits in the DCI other than the N bits in the first field are used to indicate higher modulation orders such as 16QAM, 64QAM, etc. and A combination of TBS index values. Wherein, the L bits may include at least one bit in the second field and/or bits other than the N bits in the first field. The L bits may indicate an index value in the index table as shown in Table 7, but the present application is not limited thereto.

According to the above solution, on the basis that the MCS field in the prior art DCI can indicate 14 combinations of QPSK and TBS index values in Table 5, the method provided by this application can make the DCI indicate a higher modulation order and TBS index combination of values. That is to say, compared with methods 1 and 2, method 5 does not add 1 bit to the DCI. The fewer bits in the DCI, the lower the code rate, the higher the reliability of the DCI, and the greater the probability of correct DCI decoding. . Mode 3 The 4-bit MCS field can only indicate 16 of the index values of the 32 modulation and coding schemes in Table 8. The MCS field may not be able to indicate the 14 modulation and coding schemes corresponding to QPSK in Table 5. , that is, compared with the prior art, Mode 3 cannot support some of the modulation and coding modes in Table 5. Compared with Mode 3, Mode 5 can not only support all modulation and coding modes in Table 5, but also support 16 combinations of higher-order modulation modes and TBS index values when the N bits in the first field indicate the second state value. , and no new bits are added to the DCI. Mode 4 Reallocates 4 bits of the MCS field in the DCI and N bits of another field (such as the 4-bit repetition count field), so that the reassigned MCS field is 5 bits, and the other field is N-1 bits, so Mode four cannot indicate some configuration of another domain. Compared with Mode 4, Mode 5 can support that another field in the DCI is N bits, and can also support 16 higher-order modulation modes and TBS index values when N bits in the first field indicate the second state value. , and no new bits are added to the DCI. To sum up, the solution of the fifth mode provided in this application can support scheduling of higher-order modulation on the basis of the prior art, without increasing the number of bits of DCI, and this solution can support all possible MCS, data configuration such as the number of repetitions.

In the fifth manner, when the N bits in the first field indicate the second state value, the manner in which the DCI indicates the first scheduling information may include, but is not limited to, the following possibilities:

Possibly 1, when N bits in the first field indicate the second state value, at least one bit in the second field is used to indicate the first scheduling information. Wherein, the possibility 1 may include but not limited to the following embodiments:

In an embodiment, bits other than N bits in the first field are used to indicate the second scheduling information and/or the repetition times of the DCI, where N is less than M.

For example, the first scheduling information is MCS, and the second scheduling information is the repetition times of the first data. As shown in FIG. 4 , the DCI includes a first field of 4 bits and a second field of 4 bits, when the first field in the DCI indicates a first state value (for example, a value from 0000 to 1101) , the first field is used to indicate the first MCS, and the second field in the DCI is used to indicate the number of repetitions of the first data; when the first three bits a ₁ , a ₂ , a 2 , When a ₃ indicates 111, the 4 bits b ₁ , b ₂ , b ₃ , and b _{4 of} the second field are used to indicate the second MCS, and the bits other than the N bits in the first field, that is, the bit a _{4 is} used to indicate the second MCS. The number of repetitions of the first data is indicated, but the present application is not limited thereto.

For another example, the first scheduling information is MCS, and the second scheduling information is the repetition times of the first data. As shown in FIG. 4 , the DCI includes a first field of 4 bits and a second field of 4 bits. When the first field in the DCI indicates the first state value, the first field is used to indicate the first MCS , the second field in the DCI is used to indicate the number of repetitions of the first data and/or the number of repetitions of the DCI; when the first 3 bits a ₁ , a ₂ , a ₃ in the first field in the DCI indicate 111 , the 4 bits b ₁ , b ₂ , b ₃ , and b _{4 of} the second field are used to indicate the second MCS, and the bits other than the N bits in the first field, that is, the bit a _{4 is} used to indicate the first MCS. The number of repetitions of data and the number of repetitions of DCI. a ₄ may indicate an index value, and each index value corresponds to a value of the number of repetitions of the first data and a value of the number of repetitions of the DCI. As shown in Table 12, when a ₄ indicates "0", it means that the number of repetitions of the first data is 1 and the number of repetitions of DCI is 1, and when a ₄ indicates "1", it means that the number of repetitions of the first data is 2 times And the number of repetitions of DCI is 4, but the present application is not limited to this.

When the first field in the DCI indicates the first state value, the first field is used to indicate the first MCS, and the first field in the DCI indicates the first MCS. The second field is used to indicate the number of repetitions of the first data and/or the number of repetitions of the DCI; when the first field in the DCI indicates 1110, it indicates that at least one bit in the second field is used to indicate the first scheduling information , and the number of repetitions of the first data is 1, when the first field in the DCI indicates 1111, it means that at least one bit in the second field is used to indicate the first scheduling information, and the number of repetitions of the first data is 2, but this application is not limited to this.

For example, the 2 bits c ₁ , c _{2 of} the third field may indicate one of 4 index values, each of the 4 index values is associated with one value of the second scheduling information and one of the DCI repetition times The values correspond to, but the present application is not limited to.

In another implementation manner, the DCI further includes a third field, and bits other than the N bits in the first field and at least one bit in the third field together indicate the second scheduling information and/or the repetition of the DCI frequency.

FIG. 10 is a schematic flowchart of an example of a communication method provided by an embodiment of the present application.

In the communication method shown in FIG. 10 , the communication device (for example, the first device or the second device) uses the control information in the fifth manner above to schedule communication data.

S1010: The first device determines first control information for scheduling the first data.

The first device determines to send the first data to the second device, or the first device determines to receive the first data from the second device, and determines the first data, such as the first scheduling information, the second scheduling information, etc., used for the first data. scheduling information, and may also determine the number of repetitions of sending the first control information. The first control information is generated by adopting the above method 5.

For example, the first device may be a network device, the second device may be a terminal device, and the network device may determine to send the first data to the terminal device and determine the first control information for scheduling the first data. Alternatively, the network device may also determine to schedule the terminal device to send the first data, and determine the scheduling information for the terminal device to send the first data, generate the first control information and send it to the terminal device. For another example, the first device and the second device may be different terminal devices, and the first device determines to schedule the first control information of the first data to the second device, but the present application is not limited thereto.

For example, the first device may determine the modulation mode, coding mode, etc. of the first data according to the current channel condition between the first device and the second device. When the first device determines the TBS of the first data and the modulation mode using QPSK, then determines that the MCS of the first data is the first MCS, and then the first field in the first control information for scheduling the first data is used to indicate The first state value corresponding to the first MCS, for example, the first field indicates an index value corresponding to the TBS of the first data and an index value in Table 5 corresponding to the modulation mode of QPSK, that is, a value from 0000 to 1101. And, the first device may further determine that the second field in the first control information is used to indicate the second scheduling information and/or the number of repetitions of the first control information, and generate the first control information. Or, when the first device determines the TBS of the first data and adopts the modulation mode of 16QAM, then determines that the MCS of the first data is the second MCS, and then schedules the N of the first field in the first control information of the first data bits are used to indicate the second state value, bits other than the N bits in the first field and/or at least one bit in the second field are used to indicate the second MCS (which may be the first field according to the specific implementation) When the N bits in the field indicate the second state value, it indicates that the bits other than the N bits in the first field are used to indicate the second MCS, or that the L bits in the second field are used to indicate the first MCS. Two MCS, or alternatively, indicates that the bits other than the N bits in the first field and the L bits in the second field are used to indicate the second MCS). For example, the first 3 bits in the first field indicate 111, and when the first 3 bits indicate 111, it indicates that the second field in the DCI is used to indicate the second MCS, and the first device according to the TBS of the first data and The modulation mode of 16QAM is determined as the corresponding index value in Table 7, the first device determines that the second field indicates the index value, and generates the first control information, but the present application is not limited to this.

It should be noted that FIG. 10 takes the first scheduling information as an MCS as an example for description, and the first scheduling information may also be other scheduling information of data, but this is not limited in this application.

Optionally, the second device may also send capability information to the first device, where the capability information is used to indicate whether the second device supports the modulation mode corresponding to the second MCS, and the first device determines, according to the capability information, that the second device supports the first device. In the case of two modulation modes corresponding to the MCS, whether to use the modulation mode corresponding to the second MCS to modulate the data is considered when sending data to the second device. For example, the capability information is used to indicate that the second device supports a modulation mode of 16QAM. After the first device receives the capability information, if it is determined that the data adopts the 16QAM modulation mode, the N bits in the first field in the corresponding first control information indicate the second state value, and the N bits in the first field are divided by the N bits. The bits other than the bits and at least one bit in the second field are used to indicate the index value of the second MCS corresponding to 16QAM.

S1020, the first device sends the first control information and/or the first data to the second device.

The first device generates the first control information after determining the scheduling information of the first data, and sends the first control information. When the data scheduled by the first control information is downlink data or data sent by the first device to the second device, the first device also sends the first data according to the first control information. For example, the first data is modulated and encoded by using a corresponding modulation and coding manner, and the first data is repeatedly sent with the repetition times of the corresponding first data.

S1030, the second device determines the first control information.

The second device receives the first control information, and determines the first field in the first control information. When the first field indicates the first state value, it determines that the first field is used to indicate the first MCS. When the N bits of the MCS indicate the second state value, it is determined that the bits other than the N bits in the first field and/or at least one bit in the second field are used to indicate the second MCS (which may be the second MCS according to the specific implementation). When N bits in a field indicate the second state value, determine that bits other than the N bits in the first field are used to indicate the second MCS, or determine that L bits in the second field are used to indicate The second MCS, or alternatively, determine that the bits other than the N bits in the first field and the L bits in the second field together indicate the second MCS).

For example, if the second device reads the first field in the first control information, and the first 4 bits in the first field indicate 1110, the second device determines that the second field in the first control information is used to indicate the first field in the first control information. Two MCS, read the second field and determine the second MCS corresponding to the index value according to the index value indicated by the second field, that is, the modulation mode and the TBS index corresponding to the index value. When the first data is downlink data or data sent by the first device to the second device, the second device demodulates the received first data according to the modulation method in S1040, and determines the first data according to the TBS index. TBS of the first data, etc. When the first control information is the control information for scheduling the second device to send data to the first device, the second device modulates and encodes according to the modulation and coding method in S940 to generate the first data, and sends it to the first device equipment.

S1040, the second device receives or sends the first data according to the first control information.

When the first data is downlink data or data sent by the first device to the second device, the second device receives the first data according to the first control information. When the first control information is control information for scheduling the second device to send data to the first device, the second device generates first data according to the first control information and sends it to the first device.

The DCI for scheduling the first data (that is, an example of the first control information) includes a first field and a second field, the first field includes M bits, and the second field includes K bits, as shown in FIG. 2 . Wherein, M and K are integers greater than or equal to 1. And, the first field is used to indicate the modulation and coding mode of the first data, and the second field is used to indicate the second scheduling information of the first data;

When the second field indicates a first state value, the first field is used to indicate the first modulation and coding mode, wherein the first state value corresponds to a value of the second scheduling information;

When the second field indicates a second state value, the first field is used to indicate the second modulation and coding mode, wherein the second state value corresponds to a value of the second scheduling information, the first modulation The modulation order corresponding to the coding mode is 1 or 2, and the modulation order corresponding to the second modulation and coding mode is 4 or 6.

Optionally, the first state value is a state value in a first set, the second state value is a state value in a second set, and the first set and the second set have no intersection.

For example, the DCI may be uplink scheduling DCI, and the second field may be a subcarrier indication field, that is to say, the second scheduling information may be subcarrier indication information used to indicate subcarriers used to carry uplink data, and may also be referred to as subcarrier indication information. Indicates the field for subcarrier scheduling. In the prior art, different subcarrier spacings correspond to different numbers of subcarriers. For example, for a 180kHz uplink bandwidth, there are 48 subcarriers when the subcarrier spacing is 3.75kHz, and 12 subcarriers when the subcarrier spacing is 15kHz. The subcarrier indication field includes 6 bits. When the subcarrier spacing is configured as 3.75kHz, the value indicated by the subcarrier indication field is the sequence number of the subcarrier to be scheduled, so it includes a total of 48 states (ie, 0 to 47). When When the subcarrier spacing is configured as 15 kHz, the subcarrier indication field indicates an index value I _{sc in} Table 16, indicating that the subcarrier corresponding to the index value is scheduled, as shown in Table 16, including a total of 19 states, namely The index values from 0 to 11 indicate that one subcarrier with the same subcarrier sequence number as the index value is scheduled, and the index values from 12 to 15 indicate that three subcarriers are scheduled. The calculation formula is obtained. The index values of 16 and 17 indicate that 6 subcarriers are scheduled, and the index value of 18 indicates that 12 subcarriers are scheduled. Therefore, the 6 bits of the subcarrier indication field indicate at most 48 states, of which 16 states (ie, 48 to 63) are reserved because they are not used.

This application proposes that when the subcarrier indication field indicates 0 to 47, the scheduled subcarriers are determined according to the prior art, and when the subcarrier indication field indicates 0 to 47, it indicates that the first field in the DCI indicates the first MCS; When the subcarrier indication field indicates 48 to 63, it indicates that the subcarrier indication field indicates the index value in Table 17, wherein the subcarrier corresponding to the index value is scheduled, and when the subcarrier indication field indicates 48 to 63, it indicates that the subcarrier indication field indicates the index value in Table 17. The first field in the DCI indicates the second MCS. Wherein Table 16 and Table 17 may be the same table, for example, the index value in one table ranges from 0 to 54, and the subcarriers allocated in Table 17 are only an example of the present application, and the present application is not limited thereto.

For example, when the first data is modulated and encoded using the first MCS (for example, QPSK, the TBS index value is 2), and 6 subcarriers are scheduled to carry the first data, the subcarrier indication in the DCI that schedules the first data The 6 bits of the field indicate the index value (16 or 17) corresponding to the scheduling 6 subcarriers in the 0 to 47, indicating that the first data adopts the first MCS, and the MCS field in the DCI indicates the MCS index value in Table 5 MCS of 2. When the first data adopts the second MCS (such as 16QAM, the TBS index value is 11), and 6 subcarriers are scheduled to carry the first data, the 6 bits of the subcarrier indication field in the DCI for scheduling the first data indicate 48 The index value (52 or 53) corresponding to the scheduling 6 subcarriers in 54 indicates that the first data adopts the second MCS, and the MCS field in the DCI indicates the MCS with the MCS index value of 1 in Table 7, but this The application is not limited to this.

In addition, the communication method shown in FIG. 10 may also use the control information in the sixth mode above to schedule communication data

For example, in S1010, the first device determines the MCS of the first data, and in the case where the first MCS is used for the first data, determines that the subcarrier indication field in the first control information for scheduling the first data indicates one of 0 to 47. An index value, in the case that the first data adopts the second MCS, the first device determines an index value in the subcarrier indication field indications 48 to 54 in the first control information, and generates the first control information. In S1020, the first device sends the first control information to the second device, and when the first data is the data sent by the first device to the second device, the first device generates and sends the first data according to the first control information to the second device. The second device determines the first control information in S1030, and specifically, determines whether the MCS field indicates the first MCS or the second MCS according to the index value range indicated by the subcarrier indication field, so as to correctly read the MCS. When the first data is the data sent by the first device to the second device, the second device receives the first data according to the first control information in S1040; when the first control information is used to schedule the second device to send to the second device When a device sends the first data, the second device performs modulation and coding according to the first control information, etc., to generate the first data and send the first data to the first device, but the present application is not limited to this.

According to the above solution, compared with Modes 1 and 2, Mode 6 does not add 1 bit to the DCI. The less the number of bits in the DCI, the lower the code rate, so that the DCI is easier to decode correctly. Method 3 The 4-bit MCS field can only indicate 16 of the index values of the 32 modulation and coding methods in Table 8. The MCS field may not be able to indicate the 14 modulation and coding methods corresponding to the original QPSK in Table 5. , that is, compared with the prior art, Mode 3 cannot support some of the modulation and coding modes in Table 5. Compared with mode 3, mode 6 can support all modulation and coding modes in Table 5, and can also support 16 combinations of higher-order modulation modes and TBS index values when the second field indicates the second state value, and there is no combination in DCI. Added the number of bits in . Mode 4 Reallocates 4 bits of the MCS field in the DCI and N bits of another field (such as the 4-bit repetition count field), so that the reassigned MCS field is 5 bits, and the other field is N-1 bits, so Mode four cannot indicate some configuration of another domain. Compared with Mode 4, Mode 6 can not only support another field in the DCI as N bits, but also support 16 combinations of higher-order modulation modes and TBS index values when the second field indicates the second state value, and no Added number of bits in DCI. To sum up, the solution of the sixth mode provided by the present application can support the scheduling of high-order modulation on the basis of the prior art, and does not increase the number of bits of DCI, and this solution can support all possible MCS and data repetition in the prior art. configuration, etc.

A first DCI format is specified, and the first DCI format can indicate that the data adopts a modulation order such as 16QAM or 64QAM. Optionally, the DCI in the first DCI format may be scrambled by a first scrambling code sequence.

Optionally, the first DCI format may include a first field, and the first field may be used to indicate at least two items of the following scheduling information:

Modulation and coding mode, data repetition times, DCI repetition times or subcarrier scheduling indication information;

The first field may indicate an index value, where the index value corresponds to the value of at least two items in modulation and coding mode, data repetition times, DCI repetition times, or subcarrier scheduling indication information.

For example, if the first field is used to indicate the number of repetitions of the MCS and the data, the first field may indicate an index value, and the index value corresponds to a value of the MCS and a value of the number of repetitions. For example, the first field indicates an index value as in Table 18, wherein each index value corresponds to an index value of an MCS, the modulation order and the TBS index value can be determined according to the index value of the MCS, and each of the index values in Table 18 The index value also corresponds to the value of the number of repetitions of a data. Therefore, according to the index value indicated by the first field, the modulation order, the TBS, and the repetition times of the data can be determined.

In the downlink solution of the prior art, as shown in Table 4, the MCS field occupies 4 bits, the data repetition count field occupies 4 bits, and a total of 8 bits are required for the control information to indicate the MCS field and the data repetition count field. According to the solution of the seventh manner, for example, the first field is used to indicate the repetition times of MCS and data, and the number of bits occupied by the first field is less than 8 bits, because when the index value indicated by the first field corresponds to the MCS field When a value of is greater than X, such as X=15, the number of repetitions of data may be 1 or 2. In this case, the first field does not need to jointly indicate the MCS greater than 15 and the number of repetitions of data greater than 2. Therefore, the number of bits occupied when the first field jointly indicates the repetition times of the MCS and the data is less than 8 bits in the prior art. To sum up, when the solution of the seventh application provides at least two items of modulation and coding mode, data repetition times, DCI repetition times, or subcarrier scheduling indication information, it can occupy less than the indication mode in the prior art. , so as to reduce the bit number overhead of DCI.

On the other hand, the existing NB-IoT has three deployment modes, including in-band operation, guard-band operation, and stand-alone opetation. The in-band operation mode is divided into the same physical cell identities (physical cell identities, PCI) in-band deployment in-band same-PCI and different physical cell identities in-band deployment in-band different-PCI.

In the case of in-band same-PCI, the terminal equipment of the NB-IoT system can consider that the NB-IoT system and the LTE system have the same PCI, and the LTE cell reference signal (CRS) has the same antenna port as the NRS. number, and LTE CRS is always available in all NB-IoT downlink subframes where NRS transmission exists. In the case of in-band different-PCI, since the PCI of the NB-IoT system is different from the PCI of the LTE system, although the terminal equipment of the NB-IoT system cannot obtain the LTE CRS in the NB-IoT downlink subframe, the , the terminal device can determine the sending position of the LTE CRS in the NB-IoT downlink subframe. That is, in the case of in-band operation, the terminal equipment of the NB-IoT system can be in the transmission position of the LTE CRS in the NB-IoT downlink subframe.

At this time, when the data adopts a high-order modulation method, it is necessary to perform power control on the downlink data to improve the robustness of transmission. The present application also provides a power control method for downlink data.

FIG. 11 is a schematic flowchart of a method for power control of downlink data provided by the present application.

S1110. The network device determines the first power ratio and the second power ratio.

The first power ratio is a ratio of the power of the first reference signal to the power of the first data signal in an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol including the first reference signal. The second power ratio is a ratio of the power of the second reference signal to the power of the second data signal in the OFDM symbol containing the second reference signal. Wherein, the OFDM symbol including the first reference signal and the OFDM symbol including the second reference signal are different OFDM symbols in the same subframe.

S1120: The network device sends the first power ratio and the second power ratio to the terminal device.

Accordingly, the terminal device receives the first power ratio and the second power ratio from the network device.

In this application, from the perspective of a network device, the existence condition of the first power ratio and the second power ratio is In-band operation.

Optionally, the first power ratio and the second power ratio in this embodiment of the present application may be carried by the same message, or may be carried by different messages.

Specifically, the power ratio may be a ratio of energy per resource element (EPRE), that is, the first power ratio is used to determine the EPRE of the first reference signal in the OFDM symbol including the first reference signal and the ratio of the EPRE of the first data signal, the second power ratio is used to determine the ratio of the EPRE of the second reference signal to the EPRE of the second data signal in the OFDM symbol including the second reference signal.

Optionally, the first reference signal is a narrowband reference signal, and the second reference signal is an LTE cell reference signal.

As an example and not limitation, the terminal device is a terminal device supporting a 16QAM modulation mode or a 64QAM modulation mode. Of course, the embodiment of the present application may also be implemented in the case that the terminal device does not support 16QAM, which is not specifically limited. Optionally, the values of the first power ratio and the second power ratio may be the same or different, which are not specifically limited in this embodiment of the present application. If the values of the first power ratio and the second power ratio are the same, the network device may send both the first power ratio and the second power ratio, or the network device may only send the first power ratio or the second power ratio, which is implemented in this application. The example does not specifically limit this.

Optionally, for the third data signal in the OFDM symbol that does not include the first reference signal nor the second reference signal in the subframe, the value of the power of the third data signal may be the same as the value of the power of the third data signal including the first reference signal. The value of the first data signal in the OFDM symbol is the same, or the value of the power of the third data signal may be the same as the value of the second data signal in the OFDM symbol including the second reference signal, or, the value of the power of the third data signal may be the same as the value of the second data signal in the OFDM symbol including the second reference signal. The value of the power of the three data signals may be different from the values of the first data signal and the second data signal.

According to the above solution, by notifying the terminal equipment of the first power ratio and the second power ratio by the network equipment, power control of downlink data can be realized, and the network equipment and the terminal equipment can reach a consensus to improve transmission robustness.
