Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a method, apparatus and communication equipment for determining a transmission frequency. Background Art

[0002] Terahertz (THz) waves are defined as electromagnetic waves with a frequency of 0.1THz to 10THz and a wavelength of 3mm to 30μm. Their frequency band is between millimeter waves and far-infrared light. There are also definitions that classify electromagnetic waves with a frequency of 0.3THz to 10THz or 0.3THz to 3THz as THz waves.

[0003] However, electromagnetic wave propagation losses in the terahertz band are greater than those in lower frequency bands. Furthermore, terahertz waves experience molecular absorption losses in the atmosphere, making their propagation frequency-selective. This results in attenuation peaks in the frequency domain, which must be avoided during signal transmission. Consequently, in terahertz wireless communication systems, signal transmission typically occurs within multiple frequency windows. The distribution of these frequency windows is influenced by transmission distance, as well as air humidity / water vapor density, oxygen concentration, temperature, and air pressure. Currently, determining available transmission frequencies in the terahertz band has become a pressing issue. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a method, apparatus and communication device for determining a transmission frequency, which can solve the problem that an available transmission frequency cannot be clearly determined during transmission.

[0011] In a third aspect, an embodiment of the present application further provides an electronic device comprising a processor, a memory, and a program or instruction stored in the memory and executable on the processor, wherein the program or instruction, when executed by the processor, implements the steps of the method described in the first aspect.

[0012] In a fourth aspect, an embodiment of the present application further provides a readable storage medium, on which a program or instruction is stored, and when the program or instruction is executed by a processor, the steps of the method described in the first aspect are implemented.

It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0027] The following describes in detail the method for determining the transmission frequency provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0028] The method of the embodiment of the present application is applied to a first communication device, which may be a user device, which refers to an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. The terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a PDA, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, or a wearable device. In addition, the first communication device may also be a network-side device, which refers to a base station or a core network, etc.

[0029] like Figure 2 As shown, a method for determining a transmission frequency in an embodiment of the present application is performed by a first communication device, including:

[0030] Step 201: Acquire at least one of environmental factors and channel measurement information.

[0031] In this step, considering that transmission may be affected by the environment and / or channel, at least one of environmental factors and channel measurement information is obtained to determine the available transmission frequency. Here, the available transmission frequency is the transmission frequency resource.

[0032] Step 202: Determine a first transmission frequency resource according to at least one of the environmental factors and the channel measurement information.

[0033] In this step, according to at least one of the environmental factors and the channel measurement information acquired in step 201 , a first transmission frequency resource can be determined for subsequent transmission.

[0034] In this way, through steps 201 and 202, the first communication device can further determine the first transmission frequency resource used for subsequent transmission based on at least one of the environmental factors and channel measurement information by obtaining at least one of the environmental factors and channel measurement information. Since the first transmission frequency resource is determined taking into account the environmental and / or channel influences, it not only has availability but also can achieve better transmission.

[0035] For example, when applied to a transmission scenario in the terahertz frequency band, the molecular absorption effect will cause multiple smaller frequency windows to appear in the terahertz signal transmission. The first transmission frequency resource determined by at least one of the acquired environmental factors and channel measurement information is a transmission frequency resource available to the first communication device in the terahertz frequency band.

[0036] The first transmission frequency resource may be a continuous frequency band or a discontinuous frequency band.

[0037] Optionally, in this embodiment, the environmental factor includes at least one of the following:

[0038] Transmission distance;

[0039] Air humidity;

[0040] Oxygen concentration;

[0041] temperature;

[0042] Air pressure.

[0043] Here, the transmission distance is the transmission distance between the first communication device and the second communication device. If the first communication device is the transmitter, the second communication device is the receiver; if the second communication device is the transmitter, the first communication device is the receiver. The transmission distance can be obtained through positioning technology, such as Global Navigation Satellite System (GNSS), Radio Frequency Identification (RFID), Ultra Wide Band (UWB), Bluetooth, Wi-Fi positioning technology, or positioning technology based on mobile networks, or other related positioning technologies; it can also be known, such as in a fixed point-to-point communication scenario.

[0044] Air humidity, oxygen concentration, temperature or air pressure may be collected through relevant sensors installed on the equipment, or queried online, or obtained by other means.

[0045] Specifically, the environmental factor may be measured or determined by the first communication device, or may be measured or determined by the second communication device and then sent to the first communication device.

[0046] Optionally, among the environmental factors, transmission distance and air humidity have a greater impact on transmission than other factors and can be used as priority factors for determining transmission frequency resources.

[0047] Optionally, in this embodiment, step 202 includes:

[0048] Determining, according to a mapping relationship between frequency resources and environmental factors, a second transmission frequency resource corresponding to the environmental factor;

[0049] The first transmission frequency resource is determined according to the second transmission frequency resource.

[0050] Here, the mapping relationship between frequency resources and environmental factors is pre-established. Through the mapping relationship, the second transmission frequency resource corresponding to the acquired environmental factor can be determined, thereby determining the first transmission frequency resource.

[0051] Taking transmission distance and air humidity as an example, the established mapping relationship is shown in Table 1:

[0052] Table 1

[0053]

[0054] In this table, frequency resources are represented as frequency window sets. According to the transmission distance and air humidity, information of m*n frequency window sets can be determined. Each frequency window set includes at least one frequency window. The specific information includes the number of frequency windows, their numbers and their positions in the spectrum (center frequency, bandwidth).

[0055] Of course, in addition to direct mapping between frequency resources and environmental factors, a mapping relationship can also be established using other intermediate quantities, such as transmission loss or frequency domain channel response amplitude. Specifically, when the environmental factors are obtained, by calculating the transmission loss or frequency domain channel response amplitude of each frequency under the environmental factors, the transmission frequency resources corresponding to transmission losses less than a given threshold or frequency domain channel response amplitude greater than a given threshold are used as frequency windows to further determine the frequency window set.

[0056] Among them, for multiple environmental factors, the transmission frequency resources corresponding to each environmental factor can be independently determined first, and then the intersection of the transmission frequency resources can be determined. Figure 3 As shown, the transmission frequency resources corresponding to environmental factors 1, 2 and 3 are intersected to obtain the transmission frequency resources shown in the shaded part.

[0057] After determining the second transmission frequency resource, optionally, determining the first transmission frequency resource according to the second transmission frequency resource includes:

[0058] The second transmission frequency resource is used as the first transmission frequency resource.

[0059] That is, the second transmission frequency resource determined by the mapping relationship between the frequency resource and the environmental factor is the first transmission frequency resource.

[0060] Alternatively, optionally, before determining the first transmission frequency resource according to the second transmission frequency resource, the method further includes:

[0061] Acquire a third transmission frequency resource supported by the second communication device;

[0062] The determining the first transmission frequency resource according to the second transmission frequency resource includes:

[0063] An overlapping portion of the second transmission frequency resource and the third transmission frequency resource is selected as the first transmission frequency resource.

[0064] That is, the first transmission frequency resource is determined in combination with the second transmission frequency resource and the capability of the second communication device. Specifically, the capability is the second communication device's ability to support the terahertz frequency band, that is, the third transmission frequency resource belongs to the terahertz frequency band.

[0065] The acquiring of the third transmission frequency resource supported by the second communication device includes:

[0066] Receive the third transmission frequency resource sent by the second communication device.

[0067] Here, the second communication device sends the third transmission frequency resource it supports to the first communication device, and the first communication device receives and obtains the resource. For example, the second communication device sends a terahertz frequency band number (THz band number), and the center frequency band and frequency range corresponding to the THz band number are predefined.

[0068] Furthermore, the second communication device is a capability-aware device to the first communication device. That is, the first communication device already knows the transmission frequency resources supported by the second communication device, so there is no need for the second communication device to report its capabilities. The first communication device may know the capabilities of the second communication device because the second communication device has previously sent its capabilities.

[0069] Of course, in this embodiment, the first communication device may also use the preset frequency resources as the transmission frequency resources supported by the second communication device according to the pre-agreed agreement, such as all terahertz frequency band resources or a specific part of the terahertz frequency band resources.

[0070] Optionally, in this embodiment, determining the first transmission frequency resource according to the second transmission frequency resource includes:

[0071] According to the current first transmission scheme, selecting a first transmission frequency resource including a carrier corresponding to the first transmission scheme from the second transmission frequency resource; or,

[0072] A second transmission scheme is determined according to the second transmission frequency resources, and a transmission frequency resource including a carrier corresponding to the second transmission scheme is used as the first transmission frequency resource.

[0073] That is, the first transmission frequency resource is determined in combination with the second transmission frequency resource and the transmission scheme. Here, the transmission scheme includes carrier aggregation transmission and non-carrier aggregation transmission. For carrier aggregation transmission, the available transmission frequency resources include multiple carriers, where the multiple carriers can be contiguous or non-contiguous and can be located within the same frequency window or multiple different frequency windows in a frequency window set. For non-carrier aggregation transmission, the available transmission resources include a single carrier.

[0074] In this way, on the one hand, for a first communication device transmitting according to a set first transmission scheme, based on the first transmission scheme, a first transmission frequency resource including a carrier corresponding to the first transmission scheme is selected from the second transmission frequency resource. For example, if the first transmission scheme is carrier aggregation transmission, then a first transmission frequency resource including multiple carriers needs to be selected from the second transmission frequency resource. On the other hand, if the second transmission scheme adopted by the first communication device for transmission is determined by the second transmission frequency resource, then the first transmission frequency resource includes the carrier corresponding to the second transmission scheme. For example, if the second transmission scheme determined by the second transmission frequency resource is non-carrier aggregation transmission, then the first transmission frequency resource includes a single carrier.

[0075] Optionally, in this embodiment, determining the first transmission frequency resource according to the second transmission frequency resource includes:

[0076] According to the channel measurement information, a first transmission frequency resource that meets a first preset condition is selected from the second transmission frequency resource; wherein,

[0077] The first preset condition is that the measurement parameter belongs to the corresponding first value range.

[0078] In other words, the first transmission frequency resource is determined in combination with the second transmission frequency resource and channel measurement information. The channel measurement information includes the measured values of various measurement parameters. Thus, the first transmission frequency resource is a transmission frequency resource selected from the second transmission frequency resources that meets a first preset condition. In the first preset condition, the first value range corresponding to the measurement parameter is pre-set, and different measurement parameters may have different first value ranges.

[0079] In addition, in the above content, the first transmission frequency resource may be determined by channel measurement information without requiring environmental factors. Optionally, determining the first transmission frequency resource according to the channel measurement information includes:

[0080] selecting, according to the channel measurement information, a fourth transmission frequency resource that meets a second preset condition;

[0081] determining the first transmission frequency resource according to the fourth transmission frequency resource;

[0082] The second preset condition is that the measurement parameter belongs to the corresponding second value range.

[0083] Because the channel measurement information includes the measured values of various measurement parameters, a fourth transmission frequency resource that meets the second preset condition is first selected. In the second preset condition, the second value range corresponding to the measurement parameter is also pre-set, and different measurement parameters have different second value ranges. The first transmission frequency resource is determined based on this fourth transmission frequency resource.

[0084] Here, channel measurement information can be obtained by measuring a narrow pulse signal as the measurement signal. The bandwidth of this narrow pulse signal covers the entire terahertz frequency range to be measured. The measurement result, i.e., the channel measurement information, is obtained by analyzing the frequency domain channel response of the entire terahertz frequency range to be measured. Alternatively, a non-uniformly distributed frequency domain measurement signal can be used for measurement. The distribution of the frequency domain measurement signal is determined based on the molecular absorption spectrum peak in the terahertz band. Specifically, a denser frequency domain measurement signal is inserted near the frequency points where the absorption effect causes greater attenuation, and a sparser frequency domain measurement signal is inserted at other locations.

[0085] In this embodiment, optionally, the channel measurement information is obtained by the second communication device through measurement based on a measurement signal sent by the first communication device; or,

[0086] The channel measurement information is obtained by the first communication device through measurement based on a measurement signal sent by the second communication device.

[0087] That is, the measurement can be performed by the first communication device or the second communication device. Specifically, the first communication device sends a measurement signal and configuration associated with the currently available transmission frequency to the second communication device, and the second communication device performs the measurement and reports the measurement result. The first communication device sends information indicating the currently available transmission frequency to the second communication device, and the second communication device sends a measurement signal based on the currently available transmission frequency to the first communication device, and the first communication device performs the measurement and obtains the measurement result.

[0088] Optionally, the measurement parameters include at least one of the following: domain channel response amplitude, reference signal received power (RSRP), and signal to interference plus noise ratio (SINR). Of course, the measurement parameters are not limited to the above and are not listed here one by one.

[0089] Taking the measurement parameter RSRP as an example, if its second value range is greater than a specific RSRP threshold A, then when the RSRP value in the channel measurement information is greater than A, the transmission frequency resource corresponding to the channel measurement information is selected as the fourth transmission frequency resource. Similarly, taking the measurement parameter RSRP as an example, if its first value range is greater than a specific RSRP threshold B, then the transmission frequency resource whose RSRP value in the corresponding channel measurement information is greater than B is selected from the second transmission frequency resource as the first transmission frequency resource.

[0090] After selecting the fourth transmission frequency resource, optionally, determining the first transmission frequency resource according to the fourth transmission frequency resource includes:

[0091] The fourth transmission frequency resource is used as the first transmission frequency resource.

[0092] That is, the fourth transmission frequency resource selected through the channel measurement information is the first transmission frequency resource.

[0093] Alternatively, optionally, the determining the first transmission frequency resource according to the fourth transmission frequency resource includes:

[0094] According to the current third transmission scheme, selecting a first transmission frequency resource including a carrier corresponding to the third transmission scheme from the fourth transmission frequency resource; or,

[0095] A fourth transmission scheme is determined according to the fourth transmission frequency resource, and a transmission frequency resource including a carrier corresponding to the fourth transmission scheme is used as the first transmission frequency resource.

[0096] That is, the first transmission frequency resource is determined in combination with the fourth transmission frequency resource and the transmission scheme. Similar to the above implementation in which the first transmission frequency resource is determined in combination with the second transmission frequency resource and the transmission scheme, details are not repeated here.

[0097] Optionally, in this embodiment, after determining the first transmission frequency resource, the method further includes:

[0098] Transmission is performed based on the first transmission frequency resource.

[0099] As known from the above content, the first transmission frequency resource is a determined applicable frequency resource. Therefore, after determining the first transmission frequency resource, the first communication device subsequently performs transmission based on the first transmission frequency resource.

[0100] To ensure communication with the second communication device, optionally, in this embodiment, after determining the first transmission frequency resource, the method further includes:

[0101] Send transmission configuration information, where the transmission configuration information includes at least one of the following:

[0102] information of the first transmission frequency resource;

[0103] Listening start indication information, where the listening start indication information is used to notify the second communication device to start listening on the first transmission frequency resource and receive information from the first communication device.

[0104] In this way, the second communication device receives the transmission configuration information, can determine the first transmission frequency resource, and start listening to receive information from the first communication device. In addition to including the listening start indication information and / or information about the first transmission frequency resource, the transmission configuration information may also include other related wireless resource configuration information, which is not listed here.

[0105] Of course, the second communication device can also send information on the first transmission frequency resource, which is received by the first communication device. The first communication device and the second communication device transmit information based on the first transmission frequency resource.

[0106] The information of the first transmission frequency resource included in the transmission configuration information may include at least one of the starting position, ending position, center frequency point and frequency band length of the resource.

[0107] It should be understood that, in this embodiment, the method further includes:

[0108] A communication link is established with a second communication device.

[0109] Only through the established communication link can measurement signals, transmission configuration information, etc. be transmitted.

[0110] Optionally, the communication link may be established based on a terahertz frequency band, a millimeter wave frequency band, or other frequency bands.

[0111] In summary, the method of the embodiment of the present application takes into account the influence of the environment and / or channel, and can determine the available transmission frequency resources based on at least one of the current environmental factors and channel measurement information, especially for the terahertz frequency band. It can more reasonably utilize the transmission frequency resources in the terahertz frequency band. For example, it can reduce the protection band of the frequency point affected by the water molecule absorption effect based on environmental factors such as the distance between the transmitting and receiving ends, thereby further improving the spectrum efficiency of the terahertz wireless communication system.
