Description

Communication method and communication equipment

Technical Field

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

Background

In a wireless communication system, the role of control information is very important. The two communication devices can realize information interaction through the control information, and one communication device can control the other communication device. Taking a base station and a user equipment as an example, in an uplink communication process, after a terminal device sends uplink data to the base station, whether the base station correctly receives the uplink data or whether the transmission power needs to be reduced to avoid interference to other user devices in a cell, or if the base station fails to receive the data, the transmission power needs to be increased, and the increase is appropriate, and the like, the information base stations need to timely indicate to the user devices to adapt to different wireless transmission environments (for example, path loss, fast fading, and the like).

In the prior art, when the base station indicates the unused information to the user equipment, different fields are required to be used for indicating respectively, and each field correspondingly indicates one kind of information. With the continuous development of communication technology, future communication systems (e.g., 5G) put higher demands on efficiency, time delay and the like of data transmission. For example, with high reliability and Low Latency Communications (URLLC) technology becoming one of the trends in data transmission. The existing indication mode of the control information no longer meets the requirement of high-efficiency transmission. The control channel is less efficient in case the base station needs to indicate several kinds of information to the user equipment simultaneously.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

Hybrid Automatic Repeat reQuest (HARQ) in a wireless communication system is a technology combining Forward Error Correction (FEC) and Automatic Repeat reQuest (ARQ) methods. In the data transmission process, the FEC adds redundant information, so that the receiving end can correct a part of error information, and reduce the number of retransmissions. For the error that the FEC cannot correct, the receiving end requests the transmitting end to retransmit the data through an ARQ mechanism. The receiving end uses an error detection code, typically a Cyclic Redundancy Check (CRC), to detect whether the received data packet is erroneous. If the data packet is not erroneous, the receiving end sends an HARQ Acknowledgement (ACK) message to the sending end. If the data packet is in error, the receiving end discards the data packet and feeds back a HARQ non-Acknowledgement (NACK) information to the transmitting end. After receiving the NACK, the transmitting end retransmits the erroneous data. If the receiving end does not receive the data sent by the sending end, the receiving end feeds back HARQ Discontinuous Transmission (DTX) information to the sending end. ACK, NACK, DTX are collectively referred to as HARQ-ACK.

In the prior art, for uplink transmission, a base station feeds back HARQ-ACK information of uplink data to a terminal device through a channel dedicated for uplink data HARQ-ACK transmission. Or indicate HARQ-ACK information through a New Data Indication (NDI) field in a control channel of the uplink scheduling grant.

In a wireless communication system, control of uplink transmission power is very important. Through the uplink power control, the user equipment can not only ensure the quality of uplink data transmission, but also reduce the interference to other user equipment in the system. Meanwhile, the network device can adapt uplink transmission to different wireless transmission environments through uplink power control, such as path loss, shadowing, fast fading, mutual interference between different terminal devices in a cell or between cells, and the like.

In the prior art, a base station mainly controls uplink transmission power of a UE in two ways. One mode is that a base station indicates a UE to Transmit uplink data through a Control channel of an uplink scheduling grant, and information of a Cell Radio Network Temporary Identifier (C-RNTI) of the UE is carried in Control channel indication information of the uplink scheduling grant, and a Transmit Power Control request (TPC Command) field in the Control channel of the uplink scheduling grant indicates an adjustment amount of Power used for transmitting the uplink data to the UE. In another mode, the base station indicates TPC command to the UEs in the control signaling for UE group power adjustment, where the control signaling includes the power adjustment amount of each UE in a specific UE group, and does not include other scheduling indication information. The control signaling for power adjustment carries identification information TPC-RNTI of the UE group. And the UE acquires the control signaling of the UE group to which the UE belongs according to the TPC-RNTI and determines the specific position of the TPC Command sent to the UE by the base station in the control signaling for adjusting the power of the UE group according to the TPC-RNTI configured by the base station.

The beam setting information includes at least one of quasi co-location QCL (quasi co-location) indication, transmission beam information, transmit/receive beam pair information, and the like. Or the beam setting information includes a reference signal index and at least one of the following information corresponding to the reference signal index: reference Signal received power rsrp (reference Signal Receiving power); or Reference Signal Receiving Quality (RSRQ); or Rank Indication (RI); or a Channel Quality Indicator (CQI).

With The continuous development of communication technology, high reliability and Low Latency Communications (URLLC) technology, which is a fifth Generation (The 5th Generation, 5G) mobile communication technology, is one of The future data transmission trends. URLLC technology places higher demands on the latency and efficiency of data transmission. Then, how to implement control of the transmission power of the user equipment and further improve the efficiency of data transmission in the new generation communication technology of the base station becomes a problem to be solved urgently.

Conventionally, control of data transmission (including uplink transmission power, feedback of data reception, and the like) by a base station to a user equipment is instructed by control information. The control information transmitted by the base station to the user equipment generally includes a field (i.e., a bit sequence) for indicating HARQ response information, and also includes a field for indicating transmission power adjustment information. When a greater variety of information needs to be indicated, more fields are needed, each field corresponding to one type of information. The efficiency of the control channel is low.

It should be understood that the reference herein to a base station and user equipment is only an example as two communication devices. Such a problem is faced between any two communication devices that need to transmit control information.

In the prior art, a field for indicating HARQ response information and a field for indicating power adjustment information together constitute control information. And, a field for indicating HARQ acknowledgement information and a field for indicating transmission powerThe fields of the adjustment information are each indicated with a separate field. According to the prior art, if the field for indicating HARQ response information is X bits and the field for indicating power adjustment information is Y bits, then the control information needs log₂X]+[log₂Y]A bit. Number of bits [ log ] in field for indicating power adjustment information₂Y]Far greater than log₂Y, bit number [ log ] of field for indicating HARQ acknowledgement information₂X]Far greater than log₂In the case of X, [ log ] is used₂X]+[log₂Y]Bit information indicates that HARQ response information and transmission power adjustment information may correspond to log₂X]+[log₂Y]-log₂X-log₂And Y indication information reservation states. In the case where a new generation of communication technology puts higher demands on transmission efficiency, the indication efficiency of the control information is relatively low according to the method of the related art.

Therefore, the application provides a communication method which can improve the efficiency of the control channel.

The technical scheme provided by the application is suitable for a scene of transmitting the control information between the two communication devices. For example, in the uplink communication process, the base station sends control information to the terminal device. For another example, in a scenario of Device-to-Device (D2D), a scenario in which one terminal Device transmits control information to another terminal Device, and the like.

For example, the first communication device is a terminal device and the second communication device is a network device. Data transmission using an uplink Grant free (UL Grant free) is supported for URLLC traffic. The network equipment configures at least one uplink data transmission channel to the terminal equipment of the serving cell in advance through the configuration information. The configuration information of each uplink data transmission channel includes at least one of a time domain position occupied by the transmission channel, a frequency domain position occupied by the transmission channel, and a reference signal used when the terminal device performs uplink communication on the transmission channel. When the terminal equipment has the requirement of uplink data transmission, selecting one transmission resource from at least one transmission channel allocated by the network equipment, and transmitting the uplink data by using the selected transmission channel. The network device detects the uplink data sent by the terminal device on at least one transmission channel pre-configured for the terminal device. The network device configures resources for the terminal device to transmit uplink data of the UL grant free, and generally considers the following factors: time domain resources, frequency domain resources, Modulation and Coding Scheme (MCS), reference signals, repetition times K, and the like.

In consideration of the uncertainty of arrival of the URLLC service, reserving different UL grant free resources for each terminal device may cause a problem of low resource utilization efficiency. Therefore, in this embodiment of the present application, the resources for uplink data transmission of the UL grant free that the network device can select to configure for different terminal devices may be the same. However, considering UEs configured with the same time and frequency domain resources, uplink data of UL grant free may be transmitted simultaneously. Therefore, in order to enable the network device to distinguish which UE the received uplink data of the UL grant free comes from, different reference signals may be configured for UEs configured with the same time domain and frequency domain resources. Also, these different reference signals need to be orthogonal to each other. For example, the time domain position and the frequency domain position occupied by the uplink channels configured for the terminal device 1 and the terminal device 2 are the same, but only the reference signals used when the uplink data are transmitted on the resources with the same time domain position and frequency domain position are different, which is convenient for the network device to identify which terminal device has transmitted the uplink data through the reception of the reference signals.

In addition, the network device may also be configured to configure different terminal devices with different time domain resources and frequency domain resources of resources used for uplink data transmission of the UL grant free. For example, uplink channels with adjacent time-frequency resources are configured for different terminal devices. After the terminal device sends the uplink data through the resource pre-configured by the network device, it is expected to obtain HARQ response information of the network device for the uplink data sent by the terminal device. The HARQ-ACK information includes at least one of an Acknowledgement (ACK), a Negative Acknowledgement (NACK), and a Discontinuous Transmission (DTX), and the ACK, NACK, and DTX are collectively referred to as HARQ-ACK information. The method and the communication equipment provided by the application can be used for transmitting the control information between the network equipment and the terminal equipment in the scene. For example, the first communication device is a terminal device in this scenario, and the second communication device is a network device in this scenario.

Fig. 1 is a schematic interaction diagram of a method 100 of communication provided herein. Referring to fig. 1, method 100 generally includes steps 110 and 120.

110. The first communication device acquires N bits of control information from the second communication device, N ≧ 2 and an integer, and,

a part of the N bits are used for independently indicating first information, and the N bits are used for jointly indicating second information;

or the N bits have M effective states, wherein I states in the M effective states are used for indicating the first information, the rest M-I states are used for indicating the combination of the first information and the second information, I < M, and I and M are positive integers;

alternatively, the N bits have M valid states indicating a combination of the first information and the second information, I < M, I and M being positive integers.

In the embodiment of the present application, the control information is composed of N bits. Different values of the N bits may represent different meanings and thus may be used to indicate different information. The first communication device and the second communication device may preset a correspondence between the values of the N bits and the information indicated by the values according to the technical solution of the present application. Thus, after the second communication device sends the control information composed of N bits to the first communication device, the first communication device can acquire the information indicated by the current values of the N bits according to the predefined definition, thereby realizing the control of one communication device to another communication device.

Optionally, the N bits of control information are jointly coded and carried in a first indication field of a control channel. The N bits of control information correspond to the first information and/or the second information in the first indication field according to different values of the control information.

It will be appreciated that errors may occur during the transmission of information due to interference and signal attenuation during communication. Therefore, error correction and error detection (also called error correction and error detection coding) are generally required for the transmission channel to enhance the capability of information to resist various interferences during transmission in the channel, thereby improving the reliability of the system. Without loss of generality, the transmitting end can add redundant information to the original information to be transmitted, and the redundant information is related to the original information. And the receiving end detects and corrects the received information according to the correlation between the redundant information and the original information. For example, a Convolutional Code (CC) or a Polar Code (Polar) may be used to perform channel coding on the data to be transmitted.

In this embodiment, the second communication device may jointly encode the N bits of control information before transmitting the N bits of control information. The control channel sent by the second communication device carries information obtained by jointly encoding N bits. The control information may be carried in a first indication field of a control channel sent by the second communication device to the first communication device.

Also, in this case, the first indication field may be one complete field. Taking N-4 as an example, the second communication device may send the 4 bits carried in one field to the first communication device. The resources in this field may be contiguous resources.

Alternatively, the second communication device may send the 1 st bit of the 4 bits to the first communication device over the first resource. And the remaining 3 bits are carried on the second resource of the time frequency resource for transmission. In this case, the field corresponding to the first resource and the second resource is referred to herein as a first indication field.

Optionally, as an embodiment, the first information includes HARQ response information, and the second information includes at least one of transmission power adjustment information, modulation and coding scheme adjustment information, and beam setting information.

The HARQ response information is used to indicate a feedback result of the second communication device for a first channel, where the first channel is a channel configured for the first communication device to transmit data.

Further, the state of the HARQ response information includes at least one of an acknowledged state, a non-acknowledged state, and a discontinuous transmission state.

Specifically, the above respective information is explained as follows:

the power adjustment information is used for indicating the adjustment amount of the transmission power of the first communication equipment;

the modulation coding scheme adjustment information is used for indicating the adjustment amount of the modulation coding scheme of the first communication equipment;

the beam setting information comprises at least one of lobe quality information and precoding matrix indications.

Wherein the power adjustment information refers to an adjustment amount indicating the transmission power of the first communication device. The power adjustment information communication apparatus adjusts the value of the transmission power. The communication device uses a certain transmission power when transmitting data. The communication device may adjust the magnitude of the transmission power according to the feedback of the data reception side.

Modulation and Coding Scheme (MCS) is a combination of different Modulation and Coding schemes. Combinations of different modulation and coding schemes can be numbered in general so that the system invokes different communication strategies to cope with different communication environments. The MCS adjustment information is used to indicate an adjustment amount of the modulation and coding scheme of the first communication device.

Optionally, the beam setting information at least includes at least one of Quasi Co-Location (QCL) indication, transmit beam information, transmit/receive beam pair information, and the like. Or the beam setting information includes a reference signal index and at least one of the following information corresponding to the reference signal index: reference Signal Received Power (RSRP); or Reference Signal Receiving Quality (RSRQ); or Rank Indication (RI); or a Channel Quality Indicator (CQI).

Several ways of providing these N bits are described in detail below in the embodiments of the present application.

Mode 1

Some of the N bits are used to independently indicate the first information, and the N bits are used to jointly indicate the second information.

Optionally, the first information includes HARQ response information, and the second information includes at least one of transmission power adjustment information, modulation and coding scheme adjustment information, and beam setting information.

Take N-4 bits as an example. As shown in table 1-1, the first communication device determines whether the HARQ-ACK acknowledgement information is the HARQ acknowledged state, the HARQ unacknowledged state, or the HARQ discontinuous transmission state according to the first two bits of the 4 bits. The first communication device determines at least one of adjustment information of transmission power of the second communication device to the first communication device, adjustment information of a modulation and coding scheme of the second communication device to the first communication device, or beam setting information of the second communication device to the first communication device according to the 4-bit association. The corresponding relationship between the values of the first two bits in the 4-bit information and the various states of the HARQ-ACK response information is preset, and the corresponding relationship between the values of the 4-bit information and the various states of the second information is preset, as shown in table 1-1. The meaning of other values of these 4 bits of information than the states shown in table 1-1 is preserved.

TABLE 1-1

By independently indicating the first information by part of the N bits, and using the N bits for jointly indicating the second information, the indicating efficiency of the control information can be effectively improved.

Further, values of a part of the N bits include a first state and a second state. The values of partial bits in the N bits are different between the states of the second information jointly indicated by the N bits corresponding to the first state and the second state.

For example, the first state corresponding to the value of a part of bits in the N bits is used to indicate the acknowledgement state of the HARQ response information and the second information adjustment direction is reduced; and the second state corresponding to the value of part of the N bits is used for indicating the non-acknowledgement state of the HARQ response information, and the adjustment direction of the second information is increased.

For another example, the first state corresponding to the value of a part of bits in the N bits is used to indicate the acknowledgement state of the HARQ response information and the second information adjustment direction is raised; and the second state corresponding to the values of part of the N bits is used for indicating the non-acknowledgement state of the HARQ response information, and the adjustment direction of the second information is reduced.

That is, the values of a part of the N bits include a first state and a second state, the first state is used for indicating the acknowledgement state of the HARQ response information and the second information adjustment direction is the first direction, the second state is used for indicating the non-acknowledgement state of the HARQ response information and the second information adjustment direction is the second direction, and the first direction and the second direction are different. The remaining bits of the N bits are used to indicate the absolute value of the second information integer.

It should be noted that the values of the N bits may not be all used to indicate the first information or the second information. For example, the value of the N bits of information may be 2^NAnd (4) seed preparation. Wherein, only M<The N values are used for indicating the first information or the second information, and other N-M values are reserved.

See tables 1-2 for illustration below.

Tables 1 to 2

A partial bit (for example, 1 bit) of the N bits is used to indicate the first information, i.e., HARQ acknowledgement information (e.g., ACK or NACK), and implicitly indicate the adjustment direction of the second information. Several different values of the remaining (N-1) bits are used to indicate the absolute values of the different power adjustment amounts, respectively. And the N bits may jointly indicate second information, i.e., transmission power adjustment information, including a direction of power adjustment and a value of power adjustment. Wherein the direction of the power adjustment can be determined by the portion of the bits and the absolute value of the power adjustment can be determined by the remaining (N-1) bits.

When the second communication device indicates that the HARQ response information is an ACK to the first communication device, it indicates that the data sent by the first communication device is correctly received by the second communication device, and at this time, the sending power of the first communication device may be too high, which often requires the first communication device to reduce the sending power, and meets the requirement of power efficiency. Therefore, the adjustment direction of the second information may be implicitly indicated as being reduced with the ACK state of the first information. Similarly, when the second communication device indicates that the HARQ response information is NACK to the first communication device, it indicates that the data sent by the first communication device is not correctly received by the second communication device, at this time, the sending power of the first communication device may be too low, and the first communication device is often required to increase the sending power, so as to meet the requirement for data transmission reliability. Thus, the adjustment direction of the second information may be implicitly indicated as being raised with the NACK state of the first information.

In the same principle, when the second communication device indicates to the first communication device that the HARQ response information is ACK, it indicates that the data transmitted by the first communication device is correctly received by the second communication device, and at this time, the order of the modulation and coding scheme used by the first communication device to transmit the data may be too low. For example, QPSK is used. In this case, the first communication device is often required to increase the order of the modulation and coding scheme to meet the requirement of data transmission efficiency. For example, QPSK is raised to 16 QAM. Therefore, the adjustment direction of the second information may be implicitly indicated as being raised with the ACK state of the first information. Similarly, when the second communication device indicates that the HARQ response information is NACK to the first communication device, it indicates that the data sent by the first communication device is not correctly received by the second communication device, and at this time, the order of the modulation and coding scheme of the first communication device may be too high. In this case, the first communication device is often required to reduce the order of the modulation and coding scheme, so as to meet the requirement of data transmission reliability. Thus, the adjustment direction of the second information may be implicitly indicated as decreasing with the NACK state of the first information. On the basis that a part of bits of the N bits indicate the first information and implicitly indicate the adjustment direction of the second information, different values of the remaining bits may be respectively used to indicate an absolute value of a modulation value, for example, an absolute value of a transmission power adjustment value or an absolute value of a modulation coding scheme.

By independently indicating the adjustment directions of the first information and the second information by part of the N bits, and indicating the absolute value of the adjustment of the second information by other bits for the N bits, the indication efficiency of the control information can be effectively improved.

It can be understood that, in the embodiment of the present application, the control information may be specifically set to how many bits, that is, how many values of N should be specifically determined, and may be determined according to how much information amount needs to be indicated between the first communication device and the second communication device.

For example, if HARQ acknowledgement information between the first communication device and the second communication device only needs 4 kinds of information indicating ACK, NACK, increasing transmission power, decreasing transmission power, the control information may be set to include only 2 bits. And different information (or meanings) is respectively indicated by using a plurality of valid values of the 2 bits. For example, four types of information indicating ACK and NACK, increasing transmission power, and decreasing transmission power may be associated with 00, 01, 10, and 11, respectively.

For another example, the HARQ response information between the first communication device and the second communication device needs to separately indicate ACK, NACK, increase by 1dB, increase by 3dB, decrease by 1dB, decrease by 3dB, ACK, NACK. The control information requires a larger number of bits to be used. For example, the above information is indicated by using various valid values 000, 001, 010, 011, 100, 101, and 110 of 3 bits.

Based on such an idea, if the number of information types to be instructed between the first communication device and the second communication device is larger, for example, if information indicating beam adjustment, information of modulation and coding scheme MCS, and the like are also required, the number of bits N of the control information may be set to be larger. Thus using more efficient values of these N to correspond to combinations that indicate a greater variety of information.

Mode 2

The N bits have M valid states, I states of the M valid states are used for indicating first information, the other M-I states are used for indicating the combination of the first information and second information, I < M, and I and M are positive integers.

For example, the values of the N bits may not necessarily all be used to indicate the first information or the second information. For example, the value of the N bits of information may have a value of 2^NAnd (4) seed preparation. Wherein, only M<N values are valid states. Other N-M values are reserved.

In this way, the different values of the N bits correspond to several different valid states, respectively. Some of the valid states are used to indicate the first information, and the content of the first information specifically indicated by each of the some of the valid states may be predefined. The remaining valid state indicates a combination of the first information and the second information, and the state of the combination of the first information and the second information indicated by the remaining valid state may also be predefined.

Optionally, when the remaining M-I states are used to indicate a combination of the first information and the second information, the states of the second information corresponding to the remaining M-I states are different; or

When the M valid states are used to indicate a combination of the first information and the second information, states of the second information corresponding to the M states are different.

For example, N is 2, and these 2 bits have 4 valid states of 00, 01, 10, and 11, respectively. Wherein 2 states 00 and 01 of the 4 valid states are used to indicate ACK and NACK states in the HARQ acknowledgement information, respectively. The remaining 2 states are used to indicate the combination of HARQ acknowledgement information and power adjustment information. It should be noted that, in the embodiment of the present application, the states of the M-I second information corresponding to the M-I states are different, or the contents of the M-I second information corresponding to the M-I states are different from each other. That is, there is no case where the values of N bits are different, but in the combination of the first information and the second information indicated by M-I states thereof, the states of the second information are the same.

Optionally, the N bits have M valid states, and the state of the HARQ acknowledgement information indicated by I states of the M valid states includes at least one of an acknowledged state, a non-acknowledged state, and a discontinuous transmission state;

the remaining M-I states are used to indicate at least one of:

the acknowledgement status of the HARQ response information and the reduction of the second information by a preset adjustment amount;

the non-confirmation state of the HARQ response information raises the second information by a preset adjustment amount;

and the state of the discontinuous transmission of the HARQ acknowledgement information is increased by a preset adjustment amount.

See table 2-1 below for illustration.

The values "00" and "10" of the N bits are used to indicate the first information, i.e., HARQ acknowledgement information (e.g., ACK or NACK). The values "01" and "11" of the N bits are used to indicate different HARQ response information and power adjustment values.

TABLE 2-1

2-bit information	N-bit information and content of indication
		00	ACK
01	ACK, power adjustment 1
		10	NACK
11	NACK, power adjustment 2

And the second communication equipment indicates that the data sent by the first communication equipment is correctly received by the second communication equipment under the condition that the HARQ response information is ACK. In this case, the transmission power of the second communication apparatus to the first communication apparatus may be adjusted or may not be adjusted. Therefore, different values of the N-bit information may indicate the ACK status of the first information, and the transmission power of the first communication device does not need to be adjusted, or needs to be adjusted and the adjustment amount is different.

For example, the second communication device may improve the efficiency of resource usage by adjusting the modulation and coding scheme used by the first communication device to transmit data without adjusting the transmission power of the first communication device. Similarly, when the second communication device indicates that the HARQ response information is NACK to the first communication device, the transmission power of the second communication device to the first communication device may be adjusted or may not be adjusted.

Optionally, the M valid statuses are used to indicate a combination of the first information and the second information, and the combination of the first information and the second information includes at least one of the following:

Optionally, the N bits have M valid states, where I states of the M valid states are used to indicate at least one of a HARQ acknowledgement state and a discontinuous transmission state, and when the remaining M-I states are used to indicate a combination of the first information and the second information, the state of the first information corresponding to the remaining M-I states is a HARQ non-acknowledgement state. The case where the second communication device does not correctly receive the data transmitted by the first communication device is likely to be caused by the transmission power of the first communication device being too low. If the first communication device retransmits the data, or transmits another data, it is often necessary for the first communication device to increase its transmission power in order to be received correctly by the second communication device. Therefore, the HARQ response information can be implicitly indicated to be NACK by increasing the adjustment direction of the second information, and the aim of improving the indication efficiency of the control information is fulfilled.

In tables 2-2, 2-3 and 2-4 below, I states of M valid states of N bits are used to indicate the first information, and the remaining M-I states are used to indicate a combination of the first information and the second information, I < M, and I and M are positive integers, for example.

In table 2-2, I states of M valid states of N bits correspond to whether the first information is HARQ ack information or HARQ DTX information, and M-I states are used to indicate that the first information in the combination of the first information and the second information is HARQ non-ack information. In tables 2-3, I states of M valid states of N bits correspond to that the first information is HARQ acknowledgement information, and M-I states are used to indicate that the first information in the combination of the first information and the second information is HARQ non-acknowledgement information. In tables 2-4, I states of M valid states of N bits correspond to that the first information is HARQ DTX information, and the M-I states are used to indicate that the first information in the combination of the first information and the second information is HARQ non-acknowledgement information.

As illustrated in table 2-2 below, when N is 2, the 2 bits have 4 valid states, i.e., M is 4.

As shown in table 2-3 below, continuing with the example of N-2, these 2 bits have 4 valid states, i.e., M-4.

And the second communication equipment indicates that the data sent by the first communication equipment is correctly received by the second communication equipment under the condition that the HARQ response information is ACK. At this time, the transmission power of the second communication apparatus to the first communication apparatus may not be adjusted, i.e., it is not necessary to indicate the second information to the first communication apparatus. When the data sent by the first communication device is not correctly received by the second communication device, the second communication device sends the power adjustment amount to the first communication device, and when the first communication device is in the state of increasing the sending power according to the received control information, the HARQ response information sent by the second communication device to the first communication device can be judged to be NACK or, when the data sent by the first communication device is not correctly received by the second communication device, the second communication device sends an MCS mode to the first communication device, and when the first communication device is in the state of decreasing the MCS mode according to the received control information, the HARQ response information sent by the second communication device to the first communication device can be judged to be NACK.

Accordingly, the ACK state and/or the DTX state of the first information may be indicated with a partial state of the M valid states. While the second information is represented by the other of the M valid states and the first information is a NACK.

It should be noted that the other states of the M valid states represent the second information, and the first information is NACK. For indicating that the first information is NACK, an implicit indication may be provided.

Optionally, the N bits have M valid states, I states of the M valid states are used to indicate at least one of a HARQ acknowledgement state, a HARQ non-acknowledgement state, and a discontinuous transmission state, and when the remaining M-I states are used to indicate a combination of the first information and the second information, the state of the first information corresponding to the remaining M-I states is the HARQ non-acknowledgement state.

Taking tables 2-5 as examples, N-3 and M-8.

Mode 3

The N bits have M valid states indicating a combination of the first information and the second information.

In mode 3, each value of the N bits corresponds to a valid state, and each valid state indicates a combination of a first information and a second information.

Take N ═ 4 as an example. As shown in table 3, the first communication device determines, according to the current value of 4 bits of the acquired control information, information indicated by the control information sent by the second communication device. And the first communication device determines at least one of adjustment information of the transmission power of the second communication device to the first communication device, adjustment information of the modulation and coding mode of the second communication device to the first communication device, or beam setting information of the second communication device to the first communication device according to the current value of the 4 bits.

The correspondence between the value of the 4 bits and the meaning of the value is predetermined between the first communication device and the second communication device. The values of the N bits and the meaning of these values, which are not shown in table 3, are retained.

TABLE 3

By indicating the combination of the first information and the second information with these N bits, the indicating efficiency of the control information can be improved.

See Table 3-1. The first communication device acquires control information of N (N ═ 4) bits. And determining the combination of the first information and the second information corresponding to the current value according to the combination of the first information and the second information indicated by each value of the N bits agreed in advance. Thereby determining at least one of HARQ response information, power adjustment information, MCS information, beam setting information, and the like, which are indicated by the second communication apparatus.

For example, if the value of 4 bits of the control information acquired by the first communication device is 0000, the HARQ response information indicated to the first communication device by the second communication device is ACK, and the power adjustment amount is 0. This indicates that the data transmitted by the first communication device is correctly received by the second communication device, and the transmission power of the first communication device is appropriate and may not be adjusted.

For another example, if the value of the 4 bits is 0010, the HARQ response information indicated by the second communication device to the first communication device is NACK, and the transmission power needs to be adjusted according to the predetermined convention. Assuming that the power adjustment amount 2 agreed in advance is "increased by 3 dB", the first communication apparatus needs to increase the transmission power by 3dB and then transmit the data when retransmitting the data subsequently. Similarly, assuming that the pre-agreed power adjustment amount 2 is "1 dB up", the first communication device needs to increase the transmission power by 1dB when subsequently transmitting data.

For another example, if the value of the 4 bits is 0101, the HARQ response information indicated to the first communication device by the second communication device is NACK, and the index of the MCS that the first communication device needs to adopt is indicated as 0. And the first communication equipment uses the MCS corresponding to the index 0 to modulate and code the data when the data is transmitted subsequently.

In mode 3, each value of the N bits of the control information indicates a combination of one type of first information and one type of second information.

In the prior art, if one control information needs to indicate two kinds of information, two fields are required, each for indicating one kind of information. For example, the second communication apparatus needs to indicate the HARQ response information to the first communication apparatus to be NACK, and increase the transmission power by 3 dB. According to the prior art method, two fields need to be defined first, assuming that field 1 is used for indicating HARQ response information and field 2 is used for indicating power adjustment information. If field 1 uses N bits to indicate that the HARQ response information is ACK or NACK, and field 2 uses M bits to indicate the power adjustment amount, N + M bits need to be used for the control information.

In the implementation of the present application, the correspondence between the N bits of the control information and the meanings of the N bits is predefined between the two communication devices, so that a large amount of redundant states generated by the values of the N bits can be avoided, and further, the waste of resources is caused. Therefore, the technical scheme provided by the application can provide the indication efficiency of the control information.

The above tables 1-1 to 3 are only examples to illustrate the design concept of the present invention. On the basis of this, a person skilled in the art can design the indication form of the control information in more forms by simple transformation, using common knowledge in the art, based on such design concept.

120. The first communication device communicates with the second communication device according to the control information.

In step 120, the first communication device communicates with the second communication device according to information indicated by the control information acquired from the second communication device.

It will be appreciated that the process of the first communication device accordingly determining how to subsequently communicate with the second communication device is implementation specific based on the difference in information specifically indicated by the control information.

Based on the foregoing, it can be appreciated that the N bits of the control information can indicate the first information, the second information, and various different combinations of the first information and the second information thereof.

Specifically, the first information includes HARQ response information, and the second information includes at least one of transmission power adjustment information, modulation and coding scheme adjustment information, and beam setting information.

Thus, the content of information that can be indicated by N bits of control information is very large. Correspondingly, the first communication device communicates with the second communication device based on the content of the information specifically indicated by the current control information after receiving the control information of the second communication device.

Hereinafter, for convenience of description, the first information, the second information, and the combination of the first information and the second information indicated by any form of the above-described mode 1, mode 2, or mode 3, of the N bits of the control information are collectively referred to as information indicated by the control information.

For example, in the case where the control information indicates ACK information and power adjustment information, it indicates that the second communication apparatus correctly receives information transmitted by the first communication apparatus, and indicates the amount of adjustment of the transmission power. In this case, the first communication device may perform any one of the following operations:

the first communication device may stop the transmission of data in case there is no need for the first communication device to transmit data;

when the first communication device continues to have a demand for transmitting data, the first communication device may adjust the transmission power according to the power adjustment amount indicated in the control information and then continue to transmit new data.

For another example, in the case where the control information indicates NACK information and power adjustment information, it indicates that the second communication apparatus has not correctly received data transmitted by the first communication apparatus. In this case, the first communication device may perform any one of the following operations:

the first communication equipment adjusts the transmission power according to the power adjustment quantity indicated in the control information, and then continues to transmit the data which is not correctly received by the second communication equipment;

the first communication device decrements the repeat transmission count value by 1.

In order to guarantee the accuracy of data transmission. The first communication device and the second communication device may set in advance to repeat K times of transmitting data. Therefore, the initial value of the repeat transmission counter is K, which is a positive integer greater than or equal to 2. The first communication device decrements the repeat transmission count value by 1 and retransmits the data that was not correctly received by the second communication device in the case where the received control information indicates NACK.

For another example, in the case where the control information indicates NACK and the beam setting information, it indicates that the second communication apparatus has not correctly received the data transmitted by the first communication apparatus. In this case, the first communication device adjusts the beam direction according to the control information, and retransmits the data that is not correctly received by the second communication device. Alternatively, the first communication device may also subtract 1 from the repeated transmission count value.

For another example, in the case where the control information indicates NACK or DTX, indicating that the second communication apparatus did not correctly receive or did not receive the data transmitted by the first communication apparatus, the first communication apparatus re-determines a transmission power (denoted as transmission power #2) based on a rule agreed in advance with the second communication apparatus and a transmission power (denoted as transmission power #1) used when data was transmitted previously, and re-transmits the data which was not correctly received or not received by the second communication apparatus using the transmission power # 2.

Here, the rule agreed in advance may be used for how the first communication device determines the transmission power to be used when retransmitting data in the case where data transmitted by the first communication device is not correctly received by the second communication device and the second communication device does not indicate the power adjustment amount. For example, the pre-agreed rule may be that each time data is repeatedly transmitted, the transmission power used for the previous transmission of data is increased by 3 dB.

For another example, in the case where the control information indicates NACK and MCS information, it indicates that the second communication apparatus has not correctly received data transmitted by the first communication apparatus. In this case, the first communication device performs modulation coding again on the data that the second communication device has not correctly received, according to the modulation order of the MCS indicated in the control information, and then transmits the data to the second communication device.

In summary, the first communication device adaptively adjusts factors (e.g., transmission power, MCS, beam direction, and the like) affecting data reception through the content (e.g., ACK, NACK, DTX, and the like) indicated by the control information transmitted by the second communication device, so as to achieve interaction of the control information between the two communication devices, so as to improve reliability of data reception, shorten time delay, reduce signal interference to other communication devices in the vicinity as much as possible, improve efficiency of data transmission, and the like.

According to the communication method provided by the application, the corresponding relation between the N bits of the control information and the indicated information of the N bits is predefined between the two communication devices in various modes, so that a large amount of redundancy of states indicated by values of the bits of the control information in the prior art can be avoided, and the indication efficiency of the control information can be improved.

Furthermore, the efficiency of indicating the control information is improved, and meanwhile, the control of the transmission power of one communication device to another communication device, the feedback of the data receiving condition and the like are realized through the content indicated by the control information, so that the requirements of a future communication system on high efficiency, low time delay and other data transmission can be met.

It should be understood that the first communication device and the second communication device in the embodiments of the present application are only used to distinguish the two communication devices. Or, the operations performed by the first communication device and the second communication device may be interchangeable. The second communication device may also act as the first communication device, and in this case the first communication device acts as the second communication device.
