Different application scenarios have different requirements on communication delay, rate and reliability. The control information is used as scheduling information of data, firstly, correct transmission of the control information is a premise of correct transmission of the data, and secondly, the control information needs to have enough indication flexibility so as to meet communication service requirements under different application scenes. For example, in a high rate requirement scenario, the control information may indicate a mimo transmission scheme or a modulation scheme with a high modulation order, and for example, in a high reliability requirement scenario, the control information may indicate repeated data transmission to ensure reliability of data transmission. At present, in a narrowband internet of things (NB-IoT), a modulation method supported in a downlink is Quadrature Phase Shift Keying (QPSK), a modulation method supported in an uplink is Binary Phase Shift Keying (BPSK) and QPSK, and a low-speed internet of things service can be supported. High-order modulation, such as 16quadrature amplitude modulation (16 QAM), is considered to be introduced into the NB-IoT R17 to increase the data transmission rate, so as to support higher-speed internet of things services. How to instruct the scheduling of the high-order modulation by the downlink control information and how to improve the flexibility of the control information instruction on the premise of ensuring the transmission reliability of the control information are the research hotspots of the technical personnel in the field.

The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.
In addition, the terminal device may also be a terminal device in an internet of things (IoT) system. The IoT is an important component of future information technology development, and is mainly technically characterized in that articles are connected with a network through a communication technology, so that an intelligent network with man-machine interconnection and object interconnection is realized.
It should be understood that the present application is not limited to the particular form of the terminal device.
The network device in the embodiment of the present application may be any device having a wireless transceiving function. Such devices include, but are not limited to: an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a Home base station (e.g., Home evolved Node B or Home Node B, HNB), a baseband unit (BBU), an Access Point (AP) in a wireless fidelity (WIFI) system, a wireless relay Node, a wireless backhaul Node, a Transmission Point (TP), or a Transmission and Reception Point (TRP), and may also be satellite communication, V2X, D2D, M2M, and a device in vehicle networking communication that assumes a function of a network device. Alternatively, it may also be a gNB or a transmission point (TRP or TP) in a 5G (such as NR) system, or one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or it may also be a network node that constitutes the gNB or the transmission point, such as a baseband unit (BBU), or a Distributed Unit (DU), etc.
In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may further include an Active Antenna Unit (AAU). The CU implements part of the function of the gNB, and the DU implements part of the function of the gNB, for example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of a Radio Resource Control (RRC) layer and a packet data convergence layer (PDCP) layer. The DU is responsible for processing a physical layer protocol and a real-time service, and implements functions of a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a Physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing and active antenna related functions. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as the RRC layer signaling, may also be considered to be transmitted by the DU or by the DU + AAU under this architecture. It is to be understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into network devices in an access network (RAN), or may be divided into network devices in a Core Network (CN), which is not limited in this application.
The network device provides a service for a cell, and a terminal device communicates with the cell through a transmission resource (e.g., a frequency domain resource, or a spectrum resource) allocated by the network device, where the cell may belong to a macro base station (e.g., a macro eNB or a macro gNB), or may belong to a base station corresponding to a small cell (small cell), where the small cell may include: urban cell (metro cell), micro cell (microcell), pico cell (pico cell), femto cell (femto cell), etc., and these small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-rate data transmission service.
As application scenarios expand, communication demands are correspondingly increasing. For example, the application scenarios of the internet of things are various, including outdoor to indoor, and above ground to underground, and thus higher demands are made on the design of the internet of things:
coverage enhancement: many IoT terminals are in poor coverage environments, such as electric meters and water meters, and are usually installed indoors or even in basements where wireless network signals are poor, so that coverage enhancement technology is needed to solve the problem of poor coverage communication quality;
the number of terminals is huge: the number of IoT devices is much larger than the number of devices communicating person-to-person;
the service rate requirement is low, and the time delay is insensitive: data packets transmitted by IoT devices are generally small and not sensitive to latency;
very low cost: many IoT applications require very low terminal equipment costs for large-scale deployment;
low power consumption: in most cases, IoT devices are powered by batteries and are required to be able to use for more than a decade without the need to replace batteries, which requires that IoT devices can operate with very low power consumption.
To meet these higher demands, the 3rd generation partnership project (3 GPP) of the mobile communication standardization organization passed a new research topic over GERAN #62 conferences, researched methods of supporting very low complexity and low cost internet of things in cellular networks, and established a topic of NB-IoT over RAN #69 conferences.
In particular, the design of each channel and signal needs to be enhanced on the basis of the existing communication mode to meet higher requirements. For example, currently, the modulation scheme supported by NB-IoT downlink is Quadrature Phase Shift Keying (QPSK), the modulation scheme supported by uplink is Binary Phase Shift Keying (BPSK) and QPSK, and low-speed internet of things service can be supported. However, in order to increase the data transmission rate, the NB-IoT release 17 considers introducing higher-order modulation schemes, such as 16quadrature amplitude modulation (16 QAM), 64QAM, etc., to support higher-speed internet of things services. This requires design enhancements to the Downlink Control Information (DCI) to support it indicates higher order modulation schemes.
In NB-IoT, the uplink data scheduling information is indicated by DCI of format (format) N0, and each indication field (or referred to as field) and bit number in DCI format N0 are shown in table 1. The Modulation and Coding Scheme (MCS) field includes a 4-bit MCS field for indicating a modulation order and a Transport Block Size (TBS) index value. Specifically, when the subcarrier indication field indicates that 1 subcarrier is scheduled, the MCS field indicates a modulation order corresponding to an index value and a TBS index value by indicating one index value in table 2. Wherein the TBS index value corresponds to Table 3, the TBS index value being associated with the resource allocation field indicated by IRUOne TBS in table 3 may be determined. When the sub-carrier indication field indicates that 3, 6 or 12 sub-carriers are scheduled, the MCS index value indicated by the MCS field is equal to the TBS index value and the modulation order is 2, for example, as shown in table 5.

Including a 4-bit MCS field indicating a modulation order corresponding to an index value in table 5 and a TBS index value corresponding to table 6, the TBS index value corresponding to I indicated by the resource allocation fieldSFThe association may determine one TBS in table 6.

In order to enable DCI format N0 or DCI format N1 to indicate a modulation scheme to a higher order, DCI may be design-enhanced in the following ways one to four. It should be noted that, the following description only takes the case of increasing the range of the DCI indicating the modulation order as an example, and the method provided in the embodiment of the present application may also be applied to enhance other scheduling information or indication information, which is not limited in the present application.
In a first mode
And adding an indication field in the DCI, wherein the indication field is used for indicating an index table corresponding to the MCS field. For example, a 1-bit indication field is added to the DCI, and when the 1 bit indicates "0", the index table corresponding to the MCS field is denoted as an index table a, that is, when the 1 bit indicates "0", the index value denoted by the MCS field is an index value in the 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", the index table indicating the MCS domain is the index table B, that is, when the 1 bit indicates "0", the index value indicating the MCS domain is the index value in the index table B, and the modulation order in the index table B is different from the modulation order in the index table a. For example, the index table B may include 16QAM, that is, a modulation scheme having 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 embodiment, the index table a and the index table B may also be different parts in the index table C, the first part is the index table a, the second part is the index table B, when the 1 bit indicates "0", the MCS field indicates the index value corresponding to the first part, and when the 1 bit indicates "1", the MCS field indicates the index value corresponding to the second part, which is not limited in this application.

Table 7 is an example of supporting index table B, which may optionally correspond to a deployment mode.
For example, NB-IoT includes Guard-band, Standard-alone, In-band three deployment modes. In the case that the DCI is DCI Format N1 for scheduling downlink data, when the deployment mode is Guard-band or Stand-alone, the index table B may 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.

Mode two
The bit number of the MCS domain in the DCI is increased to increase the indication range of the MCS domain. For example, the MCS field is increased by 1 bit, i.e., the MCS field has 5 bits in total to indicate the modulation order and TBS index. The original 4-bit MSC field can indicate 16 modulation coding schemes, that is, 16 combinations of modulation orders and TBS index values, and the 5-bit MCS field after adding 1 bit can indicate 32 modulation coding schemes. For example, the index table corresponding to the MCS field may include 23 selectable modulation and coding schemes as shown in table 8, but the application is not limited thereto.

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

In addition, as a higher modulation order is supported, a plurality of optional TBSs may be added to the TBS index table, for example, the uplink TBS index table may be added with TBS index values 14 to 21, and the corresponding TBS values may be as shown in table 9, but the present application is not limited thereto. For another example, the downlink TBS index table may be added with TBS index values 14 to 23, and the corresponding TBS values may be as shown in table 10, but the application is not limited thereto.

And keeping the 4-bit MCS domain in the DCI, and adjusting the content in the index table corresponding to the MCS domain. That is, the modulation and coding scheme corresponding to the index value indicated by the MSC field is adjusted so that the index values 0 to 15 indicated by the 4 bits contain the modulation scheme corresponding to the higher order modulation and indicate the corresponding TBS index, which may be, for example, one index value in table 8, and the index table corresponding to the MCS field may be as shown in table 11.

Mode IV
The 4 bits of the MCS field in the DCI are reallocated to N bits of another field, for example, the 4 bits of the MCS field in the DCI and the 4 bits of the repetition number field indicating the number of data repetitions in the DCI are reallocated to total 8 bits. For example, the 8 bits may include a 5-bit MCS field and a 3-bit repetition number field. For example, the 5-bit MCS field may indicate an index value in an index table as shown in table 8, but the present application is not limited thereto. The repetition number of 3 bits may indicate a value of 8 repetition numbers, for example, a value of 8 repetition numbers may be selected from values of 16 repetition numbers indicated by the original 4-bit repetition number field to form an index table. Some or all of the 8 repetition number values may be redefined repetition number values, which is not limited in the present application.
According to the above manner, it can be achieved that the control information indicates more value ranges of one piece of scheduling information, for example, on the basis that the MCS field in the DCI can indicate BPSK and QPSK in the prior art, it can be achieved that the MCS field in the DCI can also indicate a higher-order modulation scheme, such as 16QAM or 64 QAM.
The embodiment of the application also provides the following design mode of the control information. On the basis that the control information indicates more value ranges of one scheduling information in the first design mode to the fourth design mode, the overhead of the control information is avoided being increased, and the indicating flexibility of the existing control information can be ensured.
Mode five
A DCI for scheduling first data (i.e., an example of first control information) includes a first field including M bits and a second field including K bits, as shown in fig. 2. Wherein M, K is an integer greater than or equal to 1. And the number of the first and second groups,
when the first field indicates a first status value, the first field is used for indicating first scheduling information of the first data, and the second field is used for indicating second scheduling information of the first data and/or the number of repetitions of the DCI;
when N bits in the first field indicate a second status 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, and N is an integer greater than 1 and less than or equal to M.
In one embodiment, the first scheduling information is an MCS. When the first field indicates a first status value, the first field is used to indicate a first MCS; when the N bits in the first field indicate a second status value, at least one bit in the second field and/or bits other than the N bits in the first field indicate a second MCS. And the modulation orders corresponding to the first MCS and the second MCS are different.
For example, the first field includes a as described in FIG. 31、a2、a3、a4For a total of 4 bits, the first state value may be one of the index values 0000 to 1101 in table 5. That is, when the first isWhen 4 bits of the field indicate one of 0000 to 1101 (i.e., the first state value), the first field is used to indicate the modulation scheme (i.e., QPSK) and the TBS index value corresponding to the first state value in table 5. When N bits in the first field indicate the second state value, for example, the N bits may be the first 3 bits a in the first field1、a2、a3When the 3 bits indicate 111, or the N bits may be the first field a1、a2、a3、a4There are 4 bits, and when the 4 bits indicate 1110 or 1111, L bits other than the N bits in the first field in the DCI are used to indicate a combination of a higher modulation order of 16QAM, 64QAM, etc. and a TBS index value. That is, when the first field does not indicate one of 0000 to 1101, L bits other than the N bits in the first field in the DCI are used to indicate a combination of a higher modulation order of 16QAM, 64QAM, or the like and a TBS index value. Wherein the L bits may include at least one bit in the second field and/or bits of the first field other than the N bits. The L bits may indicate one index value in an index table as shown in table 7, but the present application is not limited thereto.
According to the above scheme, on the basis that the MCS field in the DCI in the prior art can indicate 14 combinations of QPSK and TBS index values in table 5, the DCI can be indicated to a combination of a higher modulation order and TBS index value by the method provided in the present application. That is, compared to the first and second modes, the fifth mode does not add 1 bit to the DCI, and the smaller the number of bits in the DCI, the lower the code rate, the higher the reliability of the DCI, and the higher the probability that the DCI is decoded correctly. The MCS field using 4 bits in the third method may only indicate 16 of the index values of the 32 modulation and coding schemes in table 8, and the MCS field may not indicate a part of 14 modulation and coding schemes corresponding to QPSK in table 5 originally, that is, compared with the prior art, the third method cannot support the part of modulation and coding schemes in table 5. Compared with the third mode, the fifth mode 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 N bits in the first field indicate the second state value, and the number of bits is not added in DCI. The fourth way reallocates 4 bits of the MCS field in the DCI with N bits of another field (e.g., a 4-bit repetition number field) so that the reallocated MCS field is 5 bits and the another field is N-1 bits, and thus the fourth way cannot indicate some configurations of the another field. Compared with the fourth mode, the fifth mode can support that the other field in the DCI is N bits, and can also support a combination of 16 higher-order modulation modes and the TBS index value when N bits in the first field indicate the second state value, and the number of new bits in the DCI is not increased. In summary, the scheme of the fifth mode provided in the present application can support scheduling of higher order modulation based on the prior art, without increasing the number of bits of DCI, and the scheme can support all possible configurations of MCS, the number of repetitions of data, and the like in the prior art.
In the fifth mode, when N bits in the first field indicate the second status value, the DCI may indicate the first scheduling information in a mode including, but not limited to, the following possibilities:
and possibly 1, when N bits in the first field indicate a second status value, at least one bit in the second field is used to indicate the first scheduling information. Wherein the possibility 1 may include, but is not limited to, the following embodiments:
in one embodiment, bits other than N bits in the first field are used to indicate the second scheduling information and/or the number of repetitions of the DCI, where N is less than M.
For example, the first scheduling information is MCS, and the second scheduling information is the number of repetitions of the first data. As shown in fig. 4, the DCI includes a first field of 4 bits for indicating a first MCS when the first field in the DCI indicates a first status value (e.g., one of 0000 to 1101) and a second field of 4 bits for indicating a repetition number of the first data; when the first 3 bits a in the first field in DCI1、a2、a3When 111 is indicated, 4 bits b of the second field1、b2、b3、b4For indicating a second MCS, the first fieldBit a which is a bit other than the N bits4For indicating the number of repetitions of the first data, but the present application is not limited thereto.
For another example, the first scheduling information is MCS, and the second scheduling information is the number of repetitions of the first data. As shown in fig. 4, the DCI includes a first field with 4 bits and a second field with 4 bits, where the first field is used to indicate a first MCS when the first field in the DCI indicates a first status value, and 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 3 bits a in the first field in DCI1、a2、 a3When 111 is indicated, 4 bits b of the second field1、b2、b3、b4For indicating a second MCS, bit a being a bit other than the N bits in the first field4For indicating the number of repetitions of the first data and the number of repetitions of the DCI. a is4One index value may be indicated, each index value corresponding to one value of the number of repetitions of the first data and one value of the number of repetitions of the DCI. As shown in Table 12 a4When "0" is indicated, the first data is repeated 1 time and the DCI is repeated 1 time, a4When "1" is indicated, the number of repetitions of the first data is 2 and the number of repetitions of the DCI is 4, but the present application is not limited thereto.

In another embodiment, the second field further includes at least one bit for indicating second scheduling information and/or a number of repetitions of the DCI in addition to the at least one bit for indicating the first scheduling information.

In another embodiment, the DCI further includes a third field, and at least one bit in the third field is used to indicate the second scheduling information and/or the number of repetitions of the DCI.

E.g. 2 bits c of the third field1、c2One of 4 index values, each of which corresponds to one value of the second scheduling information and one value of the DCI repetition number, may be indicated, but the present application is not limited thereto.
In another embodiment, 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 collectively indicate the second scheduling information and/or the number of repetitions of the DCI.
For example, as shown in fig. 7, the first scheduling information is MCS, the DCI includes a first field with 4 bits, a second field with 4 bits, and a third field with 2 bits, when the first field in the DCI indicates the first status value, the first field is used to indicate the first MCS, the second field in the DCI is used to indicate the second scheduling information, and the second field in the DCI is used to indicate the second scheduling informationThree fields are used for indicating the repetition times of the DCI; when the first 3 bits a in the first field in DCI1、a2、a3When indicating 111, a in the first field4And c in the third field1、c2A total of 3 bits are used to indicate the second scheduling information and the DCI repetition number, and 4 bits of the second field are used to indicate the second MCS, but the present application is not limited thereto.

For example, the 5 bits indicate an index value in the table 14, which corresponds to one value of the second MCS (including the modulation order and the TBS index value), one value of the repetition number of the first data, and one value of the repetition number of the DCI. For example, if the 5 bits indicate 0000, the DCI indicates that the modulation order adopted by the first data is 4, the TBS index value is 0, the repetition number of the first data is 1, and the repetition number of the DCI is 1, but the present invention is not limited thereto.

Fig. 10 is a schematic flowchart of an example of a communication method according to an embodiment of the present application.
In the communication method illustrated in fig. 10, a communication device (e.g., a first device or a second device) schedules communication data using the control information in the above-described manner five.
S1010, the first device determines first control information for scheduling the first data.
The first device determines to transmit the first data to the second device, or the first device determines to receive the first data from the second device, and determines scheduling information of the first data, such as first scheduling information and second scheduling information, adopted by the first data, and may also determine the number of repetitions of transmitting the first control information. And generating the first control information by adopting the fifth mode.
For example, the first device may be a network device and the second device may be a terminal device, and the network device may determine to transmit first data to the terminal device and determine the first control information to schedule the first data. Or the network device may also determine to schedule the terminal device to send the first data, determine to send scheduling information of the first data by the terminal device, generate the first control information, and send the first control information to the terminal device. For another example, the first device and the second device may be different terminal devices, and the first device determines the first control information for scheduling the first data to the second device, but the application is not limited thereto.
For example, the first device may determine a modulation scheme, a coding scheme, and the like of the first data according to a 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 scheme using QPSK, and determines the MCS of the first data to be the first MCS, a first field in the first control information of the first data is scheduled to indicate a 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 of table 5 corresponding to the modulation scheme using QPSK, i.e., one value from 0000 to 1101. And the first device may also determine that a second field in the first control information is used to indicate second scheduling information and/or a 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 the modulation scheme using 16QAM, then determines that the MCS of the first data is the second MCS, then schedules N bits of a first field in the first control information of the first data to indicate the second status value, and at least one bit of a second field and/or bits of the first field except the N bits is used to indicate the second MCS (depending on the implementation, when the N bits in the first field indicate the second status value, it indicates that the bits in the first field except the N bits are used to indicate the second MCS, or indicates that L bits in the second field are used to indicate the second MCS, or indicates that the bits in the first field except the N bits and 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 the first 3 bits indicate 111 that a second field in the DCI is used to indicate a second MCS, and the first device determines the corresponding index value as in table 7 according to the TBS of the first data and the modulation scheme of 16QAM, and determines that the second field indicates the index value, and generates the first control information, but the application is not limited thereto.
Fig. 10 illustrates the first scheduling information as an MCS, but the first scheduling information may be other scheduling information of data, but the present application is not limited thereto.
Optionally, the second device may further send capability information to the first device, where the capability information is used to indicate whether the second device supports the modulation scheme corresponding to the second MCS, and when the first device determines, according to the capability information, that the second device supports the modulation scheme corresponding to the second MCS, the first device considers whether to modulate the data by using the modulation scheme corresponding to the second MCS when sending the data to the second device. For example, the capability information is used to indicate that the second device supports a modulation scheme of 16 QAM. After receiving the capability information, if it is determined that the data adopts a 16QAM modulation scheme, the first device determines that N bits in a first field of the corresponding first control information indicate a second state value, and at least one bit in a second field and bits other than the N bits in the first field are used to indicate an index value of a second MCS corresponding to 16 QAM.
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 transmits the first control information. And 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 scheme, and the first data is repeatedly transmitted by the corresponding repetition times of the first data.
S1030, the second device determines the first control information.
The second device receives the first control information, determines a first field in the first control information, determines the first field to indicate a first MCS when the first field indicates a first status value, determines bits other than the N bits in the first field and/or at least one bit in a second field to indicate a second MCS when the N bits in the first field indicate a second status value (depending on the implementation, it may be that when the N bits in the first field indicate a second status value, it is determined that bits other than the N bits in the first field are to indicate the second MCS, or it is determined that L bits in the second field are to indicate the second MCS, or it is determined that the bits other than the N bits in the first field and the L bits in the second field collectively indicate the second MCS).
For example, the second device reads a first field in the first control information, where the first 4 bits in the first field indicate 1110, then the second device determines that a second field in the first control information is used to indicate a second MCS, and reads the second field to determine the second MCS corresponding to the index value according to the index value indicated by the second field, that is, the modulation scheme and the TBS index corresponding to the index value. When the first data is downlink data or data that is sent by the first device to the second device, the second device demodulates the received first data according to the modulation scheme in S1040, and determines the TBS of the first data according to the TBS index, and the like. When the first control information is control information for scheduling the second device to send data to the first device, the second device performs modulation and coding according to the modulation and coding scheme in S940 to generate the first data, and sends the first data to the first device.
S1040, the second device receives or transmits the first data according to the first control information.
And when the first data is downlink data or data sent by the first equipment to the second equipment, the second equipment receives the first data according to the first control information. And when the first control information is control information for scheduling the second equipment to send data to the first equipment, the second equipment generates first data according to the first control information and sends the first data to the first equipment.
Mode six
A DCI for scheduling first data (i.e., an example of first control information) includes a first field including M bits and a second field including K bits, as shown in fig. 2. Wherein M, K is an integer greater than or equal to 1. The first field is used for indicating a modulation coding mode of the first data, and the second field is used for indicating second scheduling information of the first data;
when the second field indicates a first state value, the first field is used for indicating the first modulation 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 scheme, where the second state value corresponds to a value of the second scheduling information, the modulation order corresponding to the first modulation and coding scheme is 1 or 2, and the modulation order corresponding to the second modulation and coding scheme 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 do not intersect.
For example, the DCI may be an uplink scheduling DCI, and the second field may be a subcarrier indication field, that is, the second scheduling information may be subcarrier indication information used to indicate subcarriers for carrying uplink data, and may also be referred to as a subcarrier scheduling indication field. In the prior art, the number of subcarriers corresponding to different subcarrier intervals is different, for example, the number of subcarriers is different in 180kHz uplink bandwidth, 48 subcarriers are shared when the subcarrier interval is 3.75kHz, and 12 subcarriers are shared when the subcarrier interval is 15 kHz. The sub-carrier indication field comprises 6 bits, and when the sub-carrier interval is configured to be 3.75kHz, the value indicated by the sub-carrier indication field is the serial number of the scheduled sub-carrier, thus comprising 48 states (i.e. 0 to 47), and when the sub-carrier interval is configured to be 15kHz, the sub-carrier indication field indicates an index value I in the table 16scAs shown in table 16, 19 states are included, that is, index values 0 to 11 indicate that 1 subcarrier with the same sequence number as the scheduled subcarrier and index value is scheduled, index values 12 to 15 indicate that 3 subcarriers are scheduled, and the sequence numbers of the 3 subcarriers can be obtained by the calculation expressions corresponding to the index values 12 to 15 in table 16. Index values of 16, 17 indicate that 6 subcarriers are scheduled, and index value of 18 indicates that 12 subcarriers are scheduled. Therefore, the 6 bits of the subcarrier indication field indicate 48 states at most, of which 16 states (i.e., 48 to 63) are reserved since they are not used.

Where table 16 and table 17 may be the same table, such as a table with index values from 0 to 54, and the sub-carriers allocated in table 17 are only an example of the present application, and the present application is not limited thereto.

For example, when first data is modulated and encoded with a first MCS (e.g., QPSK, TBS index value of 2), and 6 subcarriers are scheduled to carry the first data, 6 bits of a subcarrier indication field in DCI scheduling the first data indicate an index value (16 or 17) corresponding to the scheduled 6 subcarriers in 0 to 47, indicating that the first data employs the first MCS, and an MCS field in the DCI indicates an MCS with MCS index value of 2 in table 5. When the first data adopts the second MCS (e.g. 16QAM, 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 scheduling the first data indicate the index values (52 or 53) corresponding to the scheduled 6 subcarriers in 48 to 54, indicating that the first data adopts the second MCS and the MCS field in the DCI indicates the MCS with MCS index value 1 in table 7, but the application is not limited thereto.
In the communication method shown in fig. 10, the control information scheduling of the sixth embodiment may be used to schedule communication data
As in S1010, the first device determines an MCS of the first data, determines one index value of subcarrier indication field indications 0 to 47 in first control information that schedules the first data in case the first data employs the first MCS, and determines one index value of subcarrier indication field indications 48 to 54 in the first control information in case the first data employs the second MCS, 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 data sent by the first device to the second device, the first device generates the first data according to the first control information and sends the first data to the second device. The second device determines the first control information, specifically, whether the MCS field indicates the first MCS or the second MCS according to the index value range indicated by the subcarrier indication field to correctly read the MCS in S1030. When the first data is data transmitted from 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 transmit the first data to the first device, the second device performs modulation coding or the like according to the first control information to generate the first data and transmit the first data to the first device, but the application is not limited thereto.
According to the scheme, compared with the first mode and the second mode, the sixth mode does not add 1 bit in the DCI, the number of bits in the DCI is less, the code rate is lower, and the DCI is easier to decode and correct. The third method only can indicate 16 index values of the 32 modulation and coding schemes in table 8 using a 4-bit MCS field, and the MCS field may not indicate a part of 14 modulation and coding schemes corresponding to QPSK in table 5 originally, that is, compared with the prior art, the third method cannot support the part of the modulation and coding schemes in table 5. Compared with the third mode, the sixth mode can support all modulation and coding modes in table 5, and can also support 16 higher-order modulation modes and combinations of TBS index values when the second field indicates the second status value, and the number of bits is not increased in DCI. The fourth way reallocates 4 bits of the MCS field in the DCI with N bits of another field (e.g., a 4-bit repetition number field) so that the reallocated MCS field is 5 bits and the another field is N-1 bits, and thus the fourth way cannot indicate some configurations of the another field. Compared with the fourth mode, the sixth mode can support that another field in the DCI is N bits, and can also support a combination of 16 higher-order modulation modes and the TBS index value when the second field indicates the second status value, and the number of bits is not increased in the DCI. In summary, the scheme of the sixth aspect of the present application can support scheduling of high-order modulation based on the prior art, without increasing the number of bits of DCI, and the scheme can support all possible configurations of MCS, the number of repetitions of data, and the like in the prior art.
Mode seven
A first DCI format is specified that is capable of indicating data to employ a modulation order of 16QAM or 64QAM, etc. Optionally, the DCI of the first DCI format may be scrambled by a first scrambling sequence.
Optionally, a first field may be included in the first DCI format, and the first field may be used to indicate at least two of the following scheduling information:
modulation coding mode, data repetition times, DCI repetition times or subcarrier scheduling indication information;
the first field may indicate an index value corresponding to values of at least two of a modulation coding scheme, a number of repetitions of data, a number of repetitions of DCI, or subcarrier scheduling indication information.
For example, the first field is used to indicate MCS and the number of repetitions of data, the first field may indicate an index value corresponding to one value of MCS and one value of the number of repetitions. For example, the first field indicates one index value as in table 18, where each index value corresponds to an index value of an MCS from which the modulation order and TBS index value can be determined, and each index value in table 18 also corresponds to a value of the number of repetitions of one data. Therefore, according to the index value indicated by the first field, the modulation order, TBS, and the number of repetitions of data can be determined.

Figure BDA0002557833560000281
In the downlink scheme of the prior art, as shown in table 4, the MCS field occupies 4 bits, the data repetition number field occupies 4 bits, and 8 bits in total are required in the control information to indicate the MCS field and the data repetition number field. According to the seventh scheme, for example, the first field is used to indicate the MCS and the number of repetitions of data, and the number of bits occupied by the first field is less than 8 bits, because when a value of the MCS field corresponding to the index value indicated by the first field is greater than X, for example, X is 15, the number of repetitions of data may be 1 or 2, and 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 first field jointly indicates the MCS and the number of repetitions of data, and occupies fewer bits than the 8 bits in the prior art. In summary, when the scheme of the seventh embodiment is applied to indicate at least two items of the modulation coding scheme, the number of repetitions of data, the number of repetitions of DCI, or the subcarrier scheduling indication information, the scheme can occupy fewer bits compared with the indication scheme in the prior art, thereby reducing the bit number overhead of DCI.
On the other hand, there are 3 deployment modes for existing NB-IoT, including in-band deployment (in-band operation), guard-band deployment (guard-band operation), and stand-alone deployment (stand-alone operation). The in-band operation mode is divided into in-band deployment of in-band sum-PCI for the same Physical Cell Identity (PCI) and in-band deployment of in-band difference-PCI for different physical cell identities.
In the case of in-band same-PCI, the terminal device of NB-IoT system may consider that the NB-IoT system and the LTE system have the same PCI, that an LTE Cell Reference Signal (CRS) has the same number of antenna ports as that of NRS, and that the LTE CRS is always available in all NB-IoT downlink subframes where NRS transmission exists. In the case of in-band differential-PCI, since the PCI of the NB-IoT system is different from the PCI of the LTE system, at this time, although the terminal device of the NB-IoT system cannot obtain the LTE CRS in the NB-IoT downlink subframe, the terminal device may determine the transmission position of the LTE CRS in the NB-IoT downlink subframe. That is, in the case of in-band operation, the terminal device of the NB-IoT system may be at the transmission location of the LTE CRS within the NB-IoT downlink subframe.
High-order modulation, such as 16quadrature amplitude modulation (16 QAM), is considered to be introduced into the NB-IoT R17 to increase the data transmission rate, so as to support higher-speed internet of things services. At this time, when the data adopts the high-order modulation method, power control needs to be performed on the downlink data to improve the robustness of transmission. The application also provides a power control method of the downlink data.
Fig. 11 is a schematic flowchart of a method for controlling downlink data power according to the present application.
S1110, the network device determines a first power ratio value and a second power ratio value.
The first power ratio is a ratio of a power of a first reference signal in an Orthogonal Frequency Division Multiplexing (OFDM) symbol containing the first reference signal to a power of a first data signal. The second power ratio is a ratio of a power of a second reference signal to a power of a second data signal in the OFDM symbol including the second reference signal. Wherein the OFDM symbol containing the first reference signal and the OFDM symbol containing 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 value and the second power ratio value from the network device.
In this application, the first power ratio and the second power ratio are present In an In-band operation from the perspective of the network device.
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, and the carrying manner and the carrying position of the first power ratio and the second power ratio in this embodiment of the present application are not specifically limited.
As an example and not by way of limitation, the first power ratio and/or the second power ratio may be carried in an SIB message or an RRC message, specifically, the RRC message may be a radioresourceconfigdetermined message, which is not specifically limited in this embodiment of the present application.
Specifically, the power ratio may be a ratio of Energy Per Resource Element (EPRE), that is, the first power ratio is used to determine a ratio of EPRE of a first reference signal in an OFDM symbol containing the first reference signal to EPRE of a first data signal, and the second power ratio is used to determine a ratio of EPRE of a second reference signal in an OFDM symbol containing the second reference signal to EPRE of a second data signal.
Optionally, the first reference signal is a narrowband reference signal, and the second reference signal is an LTE cell reference signal.
By way of example and not limitation, the terminal device is a terminal device supporting a 16QAM modulation scheme or a 64QAM modulation scheme. Of course, the embodiment of the present application may also be implemented when the terminal device does not support 16QAM, and is not particularly limited in this regard. Optionally, values of the first power ratio and the second power ratio may be the same or different, and the embodiment of the present application is not particularly limited. 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 only sends the first power ratio or the second power ratio, which is not specifically limited in this embodiment of the present application.
Optionally, for a third data signal in the OFDM symbol that does not include the first reference signal nor the second reference signal in the subframe, a value of power of the third data signal may be the same as a value of the first data signal in the OFDM symbol that includes the first reference signal, or a value of power of the third data signal may be the same as a value of the second data signal in the OFDM symbol that includes the second reference signal, or a value of power of the third data signal may be different from values of the first data signal and the second data signal.
According to the scheme, the network equipment informs the terminal equipment of the first power ratio and the second power ratio, so that the power control of the downlink data can be realized, the network equipment and the terminal equipment can achieve consensus, and the transmission robustness is improved.
