Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, and in particular to a communication method and a communication device. BACKGROUND

[0002] In a communication system, a sending device can firstly generate binary bits from information to be transmitted, then perform channel coding on the binary bit sequence, and then map the coded bit stream into modulation symbols and perform subsequent processing and transmission. A receiving device can receive a signal carrying the modulation symbols, then demodulate the signal, and then perform subsequent channel decoding.

[0003] The mapping of the bit stream into modulation symbols can use a constellation diagram method. A constellation diagram is a signal distribution diagram on a complex plane, and the points on the complex plane are constellation points. A modulation constellation diagram is a mapping of a binary bit sequence into constellation points on a complex plane.

[0004] In the prior art, modulation constellation diagrams include modulation constellation diagrams with uniformly distributed constellation points and modulation constellation diagrams with non-uniformly distributed constellation points. The modulation constellation diagram with uniformly distributed constellation points has poor performance of the communication system, and the modulation constellation diagram with non-uniformly distributed constellation points has the disadvantage of large storage overhead.

[0015] It should be understood that the first complex modulation symbol is a constellation point coordinate; the complex value set is a set of NUC complex modulation symbols, which includes all possible constellation point coordinates. The first bit is a bit stream or a binary bit, which is not limited by embodiments of the present application.

[0016] The sending device can agree with the receiving device to use the nine complex value sets as possible complex value sets, and set the correspondence between the elements in each complex value set and the first bit.

[0017] Specifically, the sending device can use the elements in any one of the nine complex value sets to modulate the first bit to generate the first modulation symbol, and the receiving device can demodulate the first modulation symbol according to the correspondence between the elements in the complex value set and the first bit to obtain the likelihood ratio of the first bit.

[0072] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 1 The communication system 100 applicable to the embodiments of this application will be described in detail.

[0073] Figure 1 This is a schematic diagram of a communication system 100 provided in an embodiment of this application. Figure 1 As shown, the communication system 100 includes a network device 101 and a terminal device 102. The network device 101 can act as a transmitting device, sending control information and / or transport blocks to the terminal device 102. Optionally, the communication system 100 may further include terminal devices 103 and 104. Terminal devices 103 and 104 can also form a communication system in which terminal device 103 acts as a transmitting device and terminal device 104 acts as a receiving device, sending control information and / or transport blocks to terminal device 104.

[0074] The embodiments of this application can be applied to a number of different scenarios, including Figure 1The scenario shown is merely an example and is not limited to this scenario. Exemplarily, for uplink transmission, the terminal device can be a sending device and the network device can be a receiving device; for downlink transmission, the network device can be a sending device and the terminal device can be a receiving device; for other scenarios, for example, transmission between network devices, one of the network devices can be a sending device and the other network device can be a receiving device; for another example, transmission between terminal devices, one of the terminal devices can be a sending device and the other terminal device can be a receiving device. Therefore, the embodiments of the present application are described below in terms of sending devices and receiving devices.

[0075] For ease of understanding, the information modulation process involved in the embodiments of the present application is first introduced below.

[0076] The sending device can generate a binary bit sequence from the information to be transmitted, then perform channel coding on the sequence, and then map the coded bit stream to modulation symbols and perform subsequent processing and transmission. Correspondingly, the receiving device will receive a signal carrying the modulation symbols, and then perform demodulation on the signal and subsequent channel decoding.

[0077] The mapping of the bit stream to the modulation symbols can be achieved through a constellation diagram, which maps the bit stream to constellation points located in a complex plane in the form of (I+Qj), where I and Q are the real and imaginary parts of the constellation points, respectively.

[0078] The constellation diagram can include a constellation diagram with uniformly distributed constellation points and a nonuniform constellation (NUC) with non-uniformly distributed constellation points.

[0079] The constellation diagram with uniformly distributed constellation points can be a quadrature amplitude modulation (QAM) with rectangular geometric characteristics. The constellation points of QAM are distributed on a two-dimensional complex plane and have the following characteristics:

[0080] The coordinates of the constellation points on the two-dimensional complex plane can be expressed by the following formula:

[0081]

[0082] where I is an integer, Q is an integer, and X is a normalization coefficient.

[0083] Exemplarily, for 16QAM (1 modulation symbol corresponding to 4 bits), the value range of I and Q can be {-3, -1, 1, 3} and X can be 10; for 64QAM (1 modulation symbol corresponding to 6 bits), the value range of I and Q can be {-7, -5, -3, -1, 1, 3, 5, 7} and X can be 42.

[0084] In the method, the constellation is determined by a modulation order, and a mapping relationship between a modulation symbol and a bit stream. The modulation order is a length of the bit stream, that is, a number of bits represented by one modulation symbol; and the mapping relationship between the modulation symbol and the bit stream defines a unique correspondence between the bit stream (01…10) and a certain constellation point (I+Qj).

[0085] The protocol defines a modulation and coding scheme (MCS) table for uplink and downlink transmission. For example, a table 5.1.3.1-1 in a technical specification (TS) 38.214 is shown in Table 1. In Table 1, a modulation order column represents all modulation orders supported by a transceiver.

[0086] Table 1

[0087]

[0088]

[0089] The terminal device can report an MCS table supported by the terminal device to the network device after an initial access stage, and the network device can issue a configuration parameter indicating to use the table to the terminal device. In subsequent uplink and downlink transmission, the network device can indicate an MCS index in the above-mentioned MSC table through an I mcs field of downlink control information (DCI) carried in a physical downlink control channel (PDCCH) so that the terminal device determines a modulation order according to the MCS index and then determines a constellation used.

[0090] For example, the terminal device supports Table 1 as an MCS table, and the network device can indicate an MCS Index in the table through an I mcs field of DCI in a PDCCH. When the I mcs field value in the DCI is 0-9, the modulation order is 2, that is, 2 bits are mapped to one modulation symbol, corresponding to one constellation; when the I mcs field value in the DCI is 10-16, the modulation order is 4, that is, 4 bits are mapped to one modulation symbol, corresponding to another constellation; and when the I mcs field value in the DCI is 17-28, the modulation order is 6, that is, 6 bits are mapped to one modulation symbol, corresponding to another constellation.

[0091] The constellation modulation mode with uniformly distributed constellation points has the same constellation under the same modulation order, and has the advantage of low storage overhead, but the performance of the system under this mode cannot reach the optimum.

[0092] The constellation modulation mode with non-uniformly distributed constellation points generally takes the constraint condition that the total power of the constellation points is equal to 1, takes the optimization target of maximizing the achievable capacity limit of the communication system, and obtains all the constellation points through searching on the two-dimensional complex plane.

[0093] Since the achievable capacity limit of the system changes with the signal-to-noise ratio of the receiving device, and the minimum demodulation threshold of the system under 10% block error rate is different for different coding rates under the same modulation order, the NUC can finally optimize different non-uniform constellations for different MCSs, thereby achieving higher achievable capacity.

[0094] The constellation modulation mode with non-uniformly distributed constellation points has different constellations under the same modulation order and different coding rates, and has the advantage of high achievable capacity, but has the disadvantage of large storage overhead.

[0095] Therefore, the embodiments of the present application provide a communication method and a communication device, and the sending device can flexibly schedule the modulation symbol set used by the receiving device during modulation or demodulation through the preconfigured NUC modulation symbol set and the MCS-NUC mapping relationship, so as to more accurately match the real-time changing channel conditions of the receiving device, reduce the storage overhead, improve the performance of the communication system, and make the overall demodulation performance of the system approximate.

[0107] S202, the sending device sends a first signal carrying the first complex-valued modulation symbol to the receiving device, and correspondingly, the receiving device receives the first signal.

[0108] S203, the receiving device determines the complex-valued set corresponding to the first complex-valued modulation symbol according to the first signal.

[0109] S204, the receiving device determines the likelihood ratio value of the first bit corresponding to the first complex-valued modulation symbol according to the first signal and the complex-valued set.

[0110] It should be understood that the first complex-valued modulation symbol is the modulation symbol mentioned above, i.e., the coordinate of the constellation point; the complex-valued set is the set of NUC complex-valued modulation symbols, which includes all possible coordinates of constellation points. The first bit is a bit stream or a binary bit, which is not limited by the embodiments of the present application.

[0111] The sending device can agree with the receiving device to use one, more or all of the nine complex-valued sets as the possible complex-valued set, and set the correspondence between the elements in each complex-valued set and the first bit.

[0112] Specifically, the sending device can use the elements in any of the nine complex-valued sets to modulate the first bit to generate the first modulation symbol, and correspondingly, the receiving device can demodulate the first modulation symbol according to the correspondence between the elements in the complex-valued set and the first bit to obtain the likelihood ratio value of the first bit.

[0113] Wherein, the receiving device can misjudge the demodulated first bit, and the ratio of the probability of correctly judging the first bit to the probability of incorrectly judging the first bit is the likelihood ratio.

[0114] The communication method and the communication device of the embodiments of the present application can modulate and demodulate the first bit by using the preconfigured complex value set and the corresponding relationship between the complex value set and the first bit, which is advantageous to reduce the storage overhead, improve the performance of the communication system, and make the overall demodulation performance of the system approximate.

[0128] Figure 3 The schematic flow chart of the communication method 300 provided by the embodiments of the present application is shown in FIG. 3. The method 300 can be applied to the communication system shown in FIG. 1, but the embodiments of the present application are not limited thereto. As shown in FIG. 2, the method 300 can include the following steps: Figure 1 Figure 3

[0130] It should be understood that the complex value set can include at least one complex value set corresponding to the modulation order of 6 or 8, or can include the set corresponding to the modulation order of 2 or 4.

[0131] S302, the network device determines at least one complex value set according to the capability information.

[0132] It should be understood that the network device can determine which complex value set is used to modulate the bit stream according to the capability information.

[0133] ​​Specifically, the network device can determine to use the at least one complex value set through the high-layer configuration parameter and the DCI, i.e., the at least one complex value set can be in the MCS table of the technical specification (TS) 38.214, for example, the MCS table 5.1.3.1-1, the MCS table 5.1.3.1-2, and the MCS table 5.1.3.1-3, etc.

[0134] It should be understood that in the MCS table 5.1.3.1-1, the MCS table 5.1.3.1-2, and the MCS table 5.1.3.1-3, if the correspondence of the modulation order, the code rate, and the complex value set is satisfied, the constellation is the complex value set, and if not, the constellation of the prior art is used according to the prior correspondence.

[0135] The network device determines to use the at least one complex value set through the high-layer configuration parameter and the DCI, and there are three implementable manners.

[0136] The first implementable manner: when the mcs-Table in the PDSCH-Config in the high-layer configuration parameter is configured with the value 'qam256', and the current PDSCH is carried by the DCI format 1_1, and the PDCCH is scheduled by the PDCCH whose cyclic redundancy check (CRC) of the DCI is scrambled by the cell radio network temporary identity (C-RNTI), the MCS table 5.1.3.1-2 is used.

[0137] It should be understood that the at least one complex value set is contained in the MCS table 5.1.3.1-2, as shown in Table Four. It should be understood that the correspondence in Table Four can be represented in the form of a table or words, or can be represented in other manners, which is not limited in the present application.

[0138] Table Four

[0139]

[0140]

[0141] The second implementation manner: when the mcs-Table in the PDSCH-Config configured by the higher layer is configured with the value 'qam64LowSE', and the higher layer does not configure the MCS-C-RNTI, the current PDSCH is scheduled by the PDCCH of the UE-specific search space, and the CRC of the DCI in the PDCCH is scrambled by the cell radio network temporary identity (C-RNTI), the MCS table 5.1.3.1-3 is used.

[0142] It should be understood that the at least one complex value set is included in the MCS table 5.1.3.1-3, as shown in Table 5. It should be understood that the correspondence in Table 5 can be represented in the form of a table or text, or in other ways, which is not limited in the present application.

[0144]

[0145]

[0146] Optionally, when the modulation order is 6 and the code rate is 438 / 1024, the complex value set can be the first complex value set.

[0147] The third implementation manner: when the higher layer configures the MCS-C-RNTI, and the current PDSCH is scheduled by the PDCCH with the CRC scrambled by the MCS-C-RNTI, the MCS table 5.1.3.1-3 is used.

[0148] It should be understood that the at least one complex value set is included in the MCS table 5.1.3.1-3.

[0149] In addition, the at least one complex value set can also be included in the MCS table 5.1.3.1-1, as shown in Table 6. It should be understood that the correspondence in Table 6 can be represented in the form of a table or text, or in other ways, which is not limited in the present application.

[0150] Table 6

[0151]

[0152]

[0153] Optionally, when the modulation order is 6 and the code rate is 438 / 1024, the complex value set can be the first complex value set; when the modulation order is 6 and the code rate is 910 / 1024, the complex value set can be the seventh complex value set; and when the modulation order is 6 and the code rate is 948 / 1024, the complex value set can be the seventh complex value set.

[0154] The network device can determine to use MCS table 5.1.3.1-1, MCS table 5.1.3.1-2, or MCS table 5.1.3.1-3 by using the high-layer configuration parameter and the DCI, and can use the at least one complex value set for modulation. That is, the method for determining the MCS table in the prior art is also applicable to the complex value set determined to be used in the embodiments of the present application.

[0155] S303, the network device generates a first complex value modulation symbol from the first bit according to the at least one complex value set.

The network device can generate a first complex value modulation symbol from the first bit by using any one of the first complex value set, the second complex value set, and the seventh complex value set.

[0157] S304, the network device sends a first signal carrying the first complex value modulation symbol to the terminal device through the DCI, and correspondingly, the terminal device receives the first signal.

[0158] It should be understood that the first signal also carries the modulation order and the code rate corresponding to the complex value set in which the first complex value modulation symbol is located.

[0159] S305, the terminal device determines the complex value set corresponding to the first complex value modulation symbol according to the modulation order and the code rate corresponding to the first signal.

[0160] Specifically, the terminal device can blindly detect the PDCCH to receive the DCI, decode the DCI, and use a preset radio network temporary identifier value to descramble the CRC. If the descrambling is successful, the terminal device receives the first signal carrying the first complex value modulation symbol, and determines the complex value set corresponding to the first complex value modulation symbol according to the modulation order and the code rate corresponding to the first signal.

[0161] S306, the terminal device determines the likelihood ratio value of the first bit corresponding to the first complex value modulation symbol according to the first signal and the complex value set.

[0162] Specifically, the terminal device determines a likelihood ratio value of the first bit corresponding to the first complex value modulation symbol according to the correspondence between the elements in the complex value set and the first bit.
