In order to solve the technical problem, the terminal device and the network device may acquire an environmental parameter, determine a communication parameter according to the environmental parameter, and perform communication based on the terahertz electromagnetic wave according to the communication parameter. Due to the fact that the communication parameters are matched with the environment parameters, the influence of the blocking effect of the atmosphere on the terahertz electromagnetic waves on the communication performance can be reduced, and the communication performance based on the terahertz electromagnetic waves is improved.

The technical means shown in the present application will be described below by way of specific examples. It should be noted that the following embodiments may exist independently or may be combined with each other, and description of the same or similar contents is not repeated in different embodiments.

Fig. 2 is a flowchart illustrating a communication method according to an embodiment of the present application. Referring to fig. 2, the method may include:

s201, the terminal equipment acquires communication parameters.

The communication parameters are determined according to the environment parameters.

The environment parameter may be an environment parameter of an environment where the terminal device is located, or an environment parameter of an environment where the network device is located. Because the distance between the terminal device and the network device is usually short, the environment parameters of the environment where the terminal device is located and the environment parameters of the environment where the network device is located are involvedThe numbers are usually the same or similar. The environmental parameter may include at least one of the following: humidity, pressure or temperature. The environmental parameters can be acquired by terminal equipment, or network equipment, or third-party equipment. Wherein humidity refers to air humidity, and is used for measuring water (H) in air₂O) ratio.

In the embodiment shown in fig. 2, the communication parameters refer to communication parameters of the terminal device, that is, parameters used by the terminal device to communicate with the network device. The communication parameters may include at least one of the following: frequency band configuration information, first indication information, transmitting power, uplink retransmission times or second indication information.

The frequency band configuration information may include frequency points and bandwidth. The terminal equipment can determine the frequency band according to the frequency point and the bandwidth.

The first indication information is used to indicate whether the terminal device performs Channel State Information (CSI) feedback. The CSI feedback refers to that the terminal device sends a channel state to the network device, so that the network device can perform corresponding processing operations according to the channel state, for example, the processing operations may include adjusting the number of retransmissions of the terminal device, adjusting the frequency band of the terminal device, and the like.

The uplink retransmission times refer to retransmission times of uplink transmission, and the uplink transmission includes at least one of the following: a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), a Physical Random Access Channel (PRACH), a channel Sounding Reference Signal (SRS), CSI, and the like.

The second indication information is used to indicate whether the terminal device enters a Radio Link Failure (RLF) or Beam Failure Recovery (BFR) procedure. Entering RLF means that the terminal device sends radio link failure information to the network device to enable the network device to reestablish Radio Resource Control (RRC) connection. The BFR procedure refers to that the terminal device sends beam failure information to the network device, so that the network device performs beam reselection.

The terminal device may obtain the communication parameters in the following two ways:

mode 1, a terminal device receives a communication parameter sent by a network device.

And 2, when the communication parameter includes at least one of the uplink retransmission times, the transmission power, the first indication information or the second indication information, the terminal device may obtain the environment parameter, and determine the communication parameter according to the environment parameter.

The communication parameters can be determined by the network device, and the terminal device receives the network device transmission

The terminal device may autonomously determine the communication parameters, or the network device may determine the communication parameters and send the communication parameters to the terminal device. For example,

s202, the terminal device communicates with the network device based on the terahertz electromagnetic wave according to the communication parameters.

When the communication parameters are different, the mode of the terminal device performing communication based on the terahertz electromagnetic wave with the network device according to the communication parameters is also different, including the following cases:

when the communication parameter is frequency band configuration information, the terminal device sends data to the network device by using the frequency domain resource corresponding to the frequency band indicated by the frequency band configuration information in the process of carrying out communication based on the terahertz electromagnetic wave with the network device.

When the communication parameter is the first indication information, if the first indication information indicates that the terminal device performs CSI feedback, the terminal device sends a channel state to the network device in a process of performing communication based on the terahertz electromagnetic wave with the network device. If the first indication information indicates that the terminal device does not perform CSI feedback, the terminal device does not send a channel state to the network device in the process of performing communication based on the terahertz electromagnetic wave with the network device.

When the communication parameter is the transmission power, the terminal device sends data to the network device according to the transmission power in the process of carrying out communication based on the terahertz electromagnetic wave with the network device.

When the communication parameter is the uplink retransmission frequency, the terminal device may retransmit the uplink data to the network device in a process that the terminal device performs communication with the network device based on the terahertz electromagnetic wave, and the retransmission frequency of the uplink data is less than or equal to the uplink retransmission frequency.

When the communication parameter is the second indication information, if the second indication information indicates that the terminal device enters the RLF or performs the BFR procedure, the terminal device sends the radio link failure information or the beam failure information to the network device in a process of performing communication based on the terahertz electromagnetic wave with the network device. If the second indication information indicates that the terminal device does not enter the RLF or perform the BFR procedure, the terminal device does not send the radio link failure information or the beam failure information to the network device in the process of performing communication based on the terahertz electromagnetic wave with the network device.

In the embodiment shown in fig. 2, during the communication based on the terahertz electromagnetic wave between the terminal device and the network device, the terminal device may acquire the communication parameters and perform the communication based on the terahertz electromagnetic wave according to the communication parameters. The communication parameters are determined according to the environment parameters, so that the communication parameters are matched with the environment parameters, the influence of the blocking effect of the atmosphere on the terahertz electromagnetic waves on the communication performance can be reduced, and the communication performance based on the terahertz electromagnetic waves is improved.

When the communication parameters are different, the processes of the terminal device acquiring the communication parameters and performing communication based on the terahertz electromagnetic wave with the network device according to the communication parameters may be different. In the following, the following description is respectively given to a process in which the terminal device acquires the communication parameters and performs communication based on the terahertz electromagnetic wave with the network device according to the communication parameters, and the process may include the following five cases:

in the first case: the communication parameter is frequency band configuration information.

When the communication parameter is frequency band configuration information, the terminal device may acquire the frequency band configuration information in the following two ways:

in the method 1, the network device determines a frequency band and sends frequency band configuration information to the terminal device, wherein the frequency band configuration information includes the frequency band.

The network device can pre-store a curve between the frequency and the molecular absorption intensity of the terahertz electromagnetic wave under different environmental parameters, and determine a frequency band according to the environmental parameters and the curve. The molecular absorption intensity of the terahertz electromagnetic wave can represent the attenuation degree of the terahertz electromagnetic wave, and the larger the molecular absorption intensity is, the larger the attenuation degree is. For example, a corresponding curve may be selected according to the environmental parameters, and a frequency band with a smaller molecular absorption intensity may be selected according to the curve.

Next, referring to fig. 3A to 3B, curves between humidity and molecular absorption intensity of the terahertz electromagnetic wave are described.

Fig. 3A is a schematic graph of a curve provided in the present application. Referring to FIG. 3A, the horizontal axis represents frequency in Hertz, and each frequency in the horizontal axis is N10¹²Hertz, N is a number on the horizontal axis. The vertical axis represents molecular absorption intensity. The curve shown in fig. 3A is a plot of frequency versus molecular absorption intensity at 100% humidity.

Fig. 3B is another graph diagram provided in the present application. Referring to FIG. 3B, the horizontal axis represents frequency in Hertz, and each frequency in the horizontal axis is N10¹²Hertz, N is a number on the horizontal axis. The vertical axis represents molecular absorption intensity. The curve shown in fig. 3B is a plot of frequency versus molecular absorption intensity at 10% humidity.

Referring to fig. 3A and 3B, when humidity is different, the curves between frequency and molecular absorption intensity are different.

For example, when the environmental parameter is pressure, the frequency point at which the molecule absorbs can be determined according to the following formula

When selecting the frequency band, the frequency point can be considered to be avoided in the selected frequency band

Wherein the content of the first and second substances,

frequency point corresponding to zero pressure of resonance, delta^i，gIs a linear offset of pressure, P₀Is a preset pressure.

The network device may send first information to the terminal device, where the first information includes frequency band configuration information determined by the network device. The first message includes at least one of: RRC signaling, media access control-control element (MAC CE), and Downlink Control Information (DCI).

And in the mode 2, the terminal equipment determines the frequency band and sends a request message including the frequency band to the network equipment, and the network equipment determines frequency band configuration information for the terminal equipment according to the request message and sends the frequency band configuration information to the terminal equipment, wherein the frequency band configuration information includes the frequency band. The request message is used for requesting the network device to determine frequency band configuration information for the terminal device according to the frequency band.

The bearer request message may be carried by at least one of: PUCCH, PUSCH, MAC-CE, RRC signaling.

It should be noted that, the process of determining the frequency band by the terminal device may refer to the process of determining the frequency band by the network device, and details are not described here. The manner in which the network device sends the frequency band configuration information to the terminal device may be referred to as manner 1, which is not described herein again.

In this case, after the terminal device obtains the frequency band configuration information, the terminal device may send uplink data to the network device using the frequency domain resource indicated by the frequency band configuration information. The frequency domain resource indicated by the frequency band configuration information is a frequency domain resource with a small interference effect of the atmosphere on the terahertz electromagnetic wave, so that if the terminal device uses the frequency domain resource to transmit uplink data to the network device, the success rate of uplink data transmission can be improved, and further, the communication performance based on the terahertz electromagnetic wave is improved.

In the second case: the communication parameter is first indication information.

The first indication information is used for indicating whether the terminal equipment carries out CSI feedback or not.

When the communication parameter is the first indication information, the terminal device may acquire the first indication information in the following two ways:

mode 1, the terminal device determines first indication information.

A threshold corresponding to the environment parameter may be set, and when the relationship between the environment parameter and the threshold satisfies a preset relationship, the first indication information is determined to indicate that the CSI feedback is performed, otherwise, the first indication information is determined to indicate that the CSI feedback is not performed.

Next, the environmental parameter is taken as an example of humidity.

The terminal device may obtain a first threshold corresponding to the humidity, and the terminal device determines whether the humidity is greater than or equal to the first threshold, if so, determines to perform CSI feedback, that is, the first indication information indicates the terminal device to perform CSI feedback, and if not, determines not to perform CSI feedback, that is, the first indication information indicates the terminal device not to perform CSI feedback.

The terminal device may obtain the first threshold value through a high-layer signaling configuration of the network device or a predefined manner.

For example, assuming that the terminal device determines that the humidity is greater than or equal to the first threshold, the first indication information is set to 1, and the value 1 is used for instructing the terminal device to perform CSI feedback. If the terminal device determines that the humidity is smaller than the first threshold, the first indication information is set to 0, and the value of 0 is used for indicating that the terminal device does not perform CSI feedback.

When the humidity is greater than or equal to the first threshold, the CSI feedback may fail due to a large blocking effect of the atmosphere on the terahertz electromagnetic wave, and therefore, the terminal device may perform CSI retransmission. The CSI retransmission number and the humidity have a corresponding relationship, and the CSI retransmission number and the humidity can be positively correlated, that is, the larger the humidity is, the larger the retransmission number is. For example, the correspondence between the number of CSI retransmissions and the humidity may be as shown in table 1:

TABLE 1

Humidity	Number of CSI retransmissions 2
		0％-20％	2
21％-40％	4
		41％-60％	6
61％-80％	8
		81％-100％	10

The corresponding relationship between the CSI retransmission times and the humidity may be configured by the network device through high-level parameters, or may be predefined.

And in the mode 2, the network equipment determines the first indication information and sends the first indication information to the terminal equipment.

It should be noted that, for the process of determining the first indication information by the network device, reference may be made to the process of determining the first indication information by the terminal device in the manner 1, which is not described herein again.

The network device may send first information to the terminal device, where the first information includes first indication information determined by the network device. The first message includes at least one of: RRC signaling, MAC CE, DCI.

In this case, after the terminal device obtains the first indication information, the terminal device may determine whether to perform CSI feedback according to the first indication information.

And if the first indication information indicates that the terminal equipment does not perform CSI feedback, the terminal equipment does not send the channel state to the network equipment.

If the first indication information indicates that the terminal device performs CSI feedback, the terminal device sends the channel state to the network device, for example, the terminal device may periodically send the channel state to the network device, or the terminal device may send the channel state to the network device at a predetermined time. After receiving the channel state, the network device may adjust communication parameters (information such as retransmission times and frequency bands) of the terminal device according to the channel state. The terminal equipment can enable the network equipment to adjust the communication parameters of the terminal equipment in time by carrying out CSI feedback, so that the adjusted communication parameters are more matched with the environmental parameters, the influence on the communication performance due to the blocking effect of the atmosphere on the terahertz electromagnetic waves is reduced, and the communication performance based on the terahertz electromagnetic waves is further improved. Further, the terminal device performs CSI feedback only in a necessary case, so that signaling overhead is small.

In the third case: the communication parameter is transmit power.

The transmit power may be an actual transmit power or a maximum transmit power.

When the communication parameter is the transmission power, the terminal device may obtain the transmission power in the following two ways:

mode 1, the terminal device determines the transmission power.

The corresponding relation between the environment parameter and the transmission power can be set, and the terminal device can determine the transmission power according to the environment parameter and the corresponding relation.

Next, the environmental parameter is taken as an example of humidity.

When the environmental parameter is humidity, a second corresponding relationship between humidity and transmission power can be obtained, and the transmission power of the terminal device is determined according to the humidity and the second corresponding relationship. The second correspondence may include a plurality of humidity intervals and a transmission power corresponding to each humidity interval. The second correspondence may be configured by the network device through high-level parameters or may be predefined.

For example, the second correspondence may be as shown in table 2:

TABLE 2

Humidity	Transmitting power
		0％-20％	A
21％-40％	B
		41％-60％	C
61％-80％	D
		81％-100％	E

Alternatively, the second correspondence may be as shown in table 3:

TABLE 3

Humidity	Transmitting power
		0％-20％	A
21％-40％	Offset of A + 1
		41％-60％	Offset of A + 2
61％-80％	Offset of A + 3
		81％-100％	Offset of A + 4

Alternatively, the second correspondence may be as shown in table 4:

TABLE 4

Humidity	Transmitting power
		0％-20％	A
21％-40％	A + weight 1 x offset
		41％-60％	A + weight 2 x offset
61％-80％	A + weight 3 x offset
		81％-100％	A + weight 4 x offset

It should be noted that tables 2 to 4 illustrate the second corresponding relationship by way of example only, and do not limit the second corresponding relationship.

Mode 2, the network device determines the transmission power and sends the transmission power to the terminal device.

It should be noted that, for the process of determining the transmission power by the network device, reference may be made to the process of determining the transmission power by the terminal device in the mode 1, and details are not described here again.

The network device may send first information to the terminal device, where the first information includes the transmission power determined by the network device. The first message includes at least one of: RRC signaling, MAC CE, DCI.

In this case, after the terminal device obtains the transmission power, the terminal device sends uplink data to the network device according to the transmission power. The transmitting power is matched with the environmental parameters, the terminal equipment transmits uplink data according to the transmitting power, energy consumption waste caused by overlarge transmitting power can be avoided, the success rate of transmitting the uplink data by the terminal equipment can be higher, and communication based on terahertz electromagnetic waves is improved.

In a fourth case: the communication parameter is the uplink retransmission times.

When the communication parameter is the uplink retransmission number, the terminal device may obtain the uplink retransmission number in the following two ways.

Mode 1, the terminal device determines the uplink retransmission times.

The corresponding relation between the environment parameter and the uplink retransmission times can be set, and the terminal equipment can determine the transmitting power according to the environment parameter and the corresponding relation.

Next, the environmental parameter is taken as an example of humidity.

When the environmental parameter is humidity, a first corresponding relationship between the humidity and the uplink retransmission times can be obtained, and the uplink retransmission times of the terminal device can be determined according to the humidity and the first corresponding relationship. The first corresponding relationship may include a plurality of humidity intervals and uplink retransmission times corresponding to each humidity interval.

For example, the first correspondence may be as shown in table 5:

TABLE 5

Humidity	Number of uplink retransmissions
		0％-20％	2
21％-40％	4
		41％-60％	6
61％-80％	8
		81％-100％	10

The first correspondence may be configured by the network device through high-level parameters or may be predefined.

And in the mode 2, the network equipment determines the uplink retransmission times and sends the uplink retransmission times to the terminal equipment.

It should be noted that, for the process of determining the uplink retransmission times by the network device, reference may be made to the process of determining the uplink retransmission times by the terminal device in the mode 1, which is not described herein again.

The network device may send first information to the terminal device, where the first information includes uplink retransmission times determined by the network device. The first message includes at least one of: RRC signaling, MAC CE, DCI.

In this case, after obtaining the uplink retransmission times, the terminal device sends uplink data to the network device according to the uplink retransmission times. The uplink retransmission times are matched with the environmental parameters, and the terminal equipment sends uplink data according to the uplink retransmission times, so that the success rate of sending the uplink data by the terminal equipment can be improved, and further, the communication based on the terahertz electromagnetic waves is improved.

In a fifth case, the communication parameter is the second indication information.

The second indication information is used for indicating whether the terminal equipment enters the RLF or carries out the BFR flow.

When the communication parameter is the second indication information, the terminal device may obtain the second indication information in the following two ways:

mode 1, the terminal device determines the second indication information.

A threshold corresponding to the environment parameter may be set, when the relationship between the environment parameter and the threshold satisfies a preset relationship, the second indication information is determined to indicate to enter the RLF or to perform the BFR procedure, otherwise, the second indication information is determined to indicate to enter the RLF or to perform the BFR procedure.

Next, the environmental parameter is taken as an example of humidity.

The terminal device may obtain a second threshold corresponding to the humidity, and determine whether the humidity is greater than or equal to the second threshold, if so, determine to enter the RLF or perform the BFR procedure, that is, the second indication information indicates the terminal device to enter the RLF or perform the BFR procedure, and if not, determine not to enter the RLF or not to perform the BFR procedure, that is, the second indication information indicates the terminal device not to enter the RLF or not to perform the BFR procedure.

The terminal device may obtain the second threshold value through a high-layer signaling configuration of the network device or a predefined manner.

For example, assuming that the terminal device determines that the humidity is greater than or equal to the second threshold, the second indication information is set to 1, and the value 1 is used to indicate that the terminal device enters the RLF or performs the BFR procedure. And if the terminal equipment judges that the humidity is smaller than the second threshold value, setting the second indication information to be 0, wherein the value of 0 is used for indicating that the terminal equipment does not enter the RLF or does not perform the BFR process.

And in the mode 2, the network equipment determines the second indication information and sends the second indication information to the terminal equipment.

It should be noted that, for the process of determining the second indication information by the network device, reference may be made to the process of determining the second indication information by the terminal device in the manner 1, which is not described herein again.

The network device may send first information to the terminal device, where the first information includes second indication information determined by the network device. The first message includes at least one of: RRC signaling, MAC CE, DCI.

In this case, after the terminal device obtains the second indication information, the terminal device may determine whether to enter the RLF or perform the BFR procedure according to the first indication information.

And if the first indication information indicates that the terminal equipment does not enter the RLF or perform the BFR process, the terminal equipment does not send fault information to the network equipment, wherein the fault information comprises radio link failure information and/or beam failure information.

If the first indication information indicates that the terminal device enters the RLF or performs the BFR procedure, the terminal device sends the failure information to the network device, for example, the terminal device may periodically send the failure information to the network device, or the terminal device may send the failure information to the network device at a predetermined time. After receiving the failure information, the network device may perform RRC reconnection or beam reselection according to the failure information, for example, if the failure information includes radio link failure information, the network device may perform RRC reconnection after receiving the failure information. If the failure information includes beam failure information, the network device may perform beam reselection after receiving the failure information. Therefore, the reliability of a wireless link between the network equipment and the terminal equipment is high, and the communication performance based on the terahertz electromagnetic wave is improved.

In the following, taking the environmental parameter as humidity as an example, the process of determining the communication parameter is described, which includes the following two cases:

in the first case: the environment parameter is humidity, and the communication parameter is downlink retransmission times.

In this case, the network device obtains a first corresponding relationship between the humidity and the downlink retransmission times, and determines the downlink retransmission times of the network device according to the environmental parameter and the first corresponding relationship.

For example, the first corresponding relationship may include a plurality of humidity intervals and downlink retransmission times corresponding to each humidity interval, and the network device may determine, in the plurality of humidity intervals, a target humidity interval in which humidity is located, and determine the downlink retransmission times corresponding to the target humidity interval as the downlink retransmission times of the network device.

In the second case: the environment parameter is humidity, and the communication parameter is transmission power of the network device.

In this case, the network device may obtain a second correspondence between the humidity and the transmission power, and determine the communication parameter of the network device according to the environmental parameter and the second correspondence.

For example, the second correspondence relationship may include a plurality of humidity intervals and transmission power corresponding to each humidity interval, and the network device may determine, in the plurality of humidity intervals, a target humidity interval in which humidity is located, and determine the transmission power corresponding to the target humidity interval as the transmission power of the network device.

S402, the network device and the terminal device conduct communication based on the terahertz electromagnetic wave according to the communication parameters of the network device.

When the communication parameters are different, the mode of the network device performing communication based on the terahertz electromagnetic wave with the terminal device according to the communication parameters is also different, including the following two cases:

when the communication parameter is the transmission power of the network device, the network device sends data to the terminal device according to the transmission power in the process of carrying out communication based on the terahertz electromagnetic wave with the terminal device.

When the communication parameter is the downlink retransmission frequency, the network device may retransmit the downlink data to the terminal device when the network device performs communication with the terminal device based on the terahertz electromagnetic wave, and the retransmission frequency of the downlink data is less than or equal to the downlink retransmission frequency.

In the embodiment shown in fig. 4, during the communication based on the terahertz electromagnetic wave between the terminal device and the network device, the network device may acquire the communication parameters and perform the communication based on the terahertz electromagnetic wave according to the communication parameters. The communication parameters are determined according to the environment parameters, so that the communication parameters are matched with the environment parameters, the influence of the blocking effect of the atmosphere on the terahertz electromagnetic waves on the communication performance can be reduced, and the communication performance based on the terahertz electromagnetic waves is improved.
