The network device in the embodiment of this application may refer to a radio access network (radio access network, RAN) node (or device) that connects the UE to the wireless network.

For example, a helicopter or drone may be configured to act as a mobile network device, and one or more cells may move based on the location of the mobile network device. In other examples, a helicopter or drone may be configured to serve as a device that communicates with another network device. In some embodiments, the network device may refer to a CU or a DU, or the network device may include a CU and a DU, or the network device may also include an AAU.

It should be understood that network equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on water; it can also be deployed on aircraft, balloons and satellites in the sky. In the embodiments of this application, there are no limitations on the network devices and the scenarios in the embodiments of this application.

It should also be understood that all or part of the functions of the network device and UE in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform).

In some communication systems, fixed uplink and downlink time slot configurations can be used in the same section of spectrum (such as the same channel). In this way, the terminal device can perform uplink transmission in the uplink time slot and perform downlink transmission in the downlink time slot. Without considering special subframes, the uplink and downlink ratio of a typical TDD system can be as shown in Figure 2. "U" in Figure 2 represents the uplink time slot, and "D" represents the downlink time slot. The following embodiments of this application "U" and "D" in the drawings have the same meaning, and will not be described again in subsequent embodiments. As shown in Figure 2, the uplink time slots and downlink time slots of the same channel are staggered in time. However, due to the limitations of fixed uplink and downlink time slot configurations, it may not be able to meet the needs of different terminal devices.

Currently, one solution is to divide the sub-channels within the spectrum range of the existing channel, and configure the sub-channels with different uplink and downlink ratios from the original channels to meet the diverse needs of different terminal devices. For example, uplink time slots and downlink time slots can be allocated to sub-channels to meet high uplink traffic requirements, or equal uplink and downlink time slots can be allocated to sub-channels to meet balanced uplink and downlink business needs.

For example, the uplink and downlink ratio of the original channel 0 can be 2U4D, that is, the first and sixth time slots are "U", and the remaining time slots are "D". Channel 0 can be used for high downlink services. Taking a terminal device that needs to perform high uplink services as an example, as shown in Figure 3, you can divide a sub-channel 1 in the original channel 0, and configure 5U1D for sub-channel 1, that is, the third time slot is "D", and the rest of the timeslot is "D". The slots are all "U" so that sub-channel 1 is used for high uplink traffic. The remaining spectrum in channel 0 can be used as sub-channel 2, and the uplink and downlink ratio of the original channel 0 (that is, 2U4D) is configured for sub-channel 2 so that sub-channel 2 can continue to be used for high downlink services.

However, this way of dividing sub-channels in the channel also has problems, that is, interference may occur between sub-channel 1 and sub-channel 2, and between sub-channel 1 and channel 0.

Figure 4 is a schematic diagram of the relationship between the frequency band, channel 0 (that is, the original channel), and sub-channels. It can be seen that sub-channel 1 is a subset of channel 0. For example, before sub-channel division, the terminal device transmits and receives according to channel 0 (for example, 100 MHz bandwidth). At this time, all terminal devices on channel 0 are in a state of transmitting or receiving at the same time. The interference of useless leakage of terminal devices to other users is mainly reflected in the reception of the base station, so the impact is not significant.

However, in addition to useful signals, the transmitted signals of terminal equipment also have useless leakage, which will cause interference to other terminal equipment. For example, when sub-channels are introduced, some terminal devices in channel 0 may be in the transmitting state (such as the terminal devices working in sub-channel 1), and other terminal devices may be in the receiving state; or, other terminal devices may be in the transmitting state, The terminal equipment in sub-channel 1 may be in the receiving state. At this time, the useless leakage generated by the terminal equipment in the transmitting state will cause direct interference to the terminal equipment in the receiving state.

The causes of interference will be described in detail below with reference to Figures 5 to 7 .

When terminal equipment transmits signals, useless out-of-band leakage will occur, causing interference to other terminal equipment. For example, when a terminal device transmits a signal, it will occupy a certain spectrum. As shown in Figure 5, the useful signal occupies a certain channel. In addition to the useful signal, some useless out-of-band leakage (such as out-of-band leakage signal) will be generated when transmitting the signal. Out-of-band leakage is mainly caused by the nonlinear characteristics of signal transmitting devices such as power amplifiers (PAs). Taking the PA as an example, when the signal passes through the PA, in addition to the useful signal being amplified, useless out-of-band leakage signals are also generated. If these out-of-band leakage signals fall into the transmission channels of other terminal equipment, they will cause interference to other terminal equipment and reduce the signal to noise ratio (SNR) of the useful signals they transmit. As shown in Figure 6, the out-of-band leakage generated by the transmit signal of UE1 falls into the transmit frequency band of UE2, which will reduce the signal-to-noise ratio of the transmit signal of UE2 from SNR1 to SNR2.

As mentioned in the above embodiment, when out-of-band leakage falls into the transmission channel of other terminal equipment, the signal-to-noise ratio of the transmitted signal will be reduced, which is viewed from the perspective of signal transmission. From the perspective of signal reception, as shown in Figure 7, when the received signal is interfered by out-of-band leakage, the sensitivity of the receiver will be deteriorated and small signals cannot be received, that is, the sensitivity will fall back and the reception coverage will be reduced. The scope will also be significantly reduced.

In order to solve one or more of the above technical problems, this application proposes a communication method and a communication device, which help reduce the impact of out-of-band leakage.

The embodiments of the present application will be described in detail below with reference to FIGS. 8 to 16 .

Figure 8 is a schematic flow chart of the communication method according to the embodiment of the present application. The method 800 shown in Figure 8 may include step S810, specifically as follows:

S810: The terminal device sends the first information to the network device.

The first information may be used to determine the communication resources of the terminal device on the first sub-channel, or the first information may be used to determine the communication resources used by the terminal device on the first sub-channel.

The first sub-channel may occupy part of the frequency domain resources of the first channel. The first channel may be channel 0 described in the previous embodiment, and the first sub-channel may be sub-channel 1 or sub-channel 2 described in the previous embodiment. The communication resource may refer to: a resource block (RB) in the first sub-channel, the transmit power on the first sub-channel, and the frequency region in the first sub-channel.

In some implementations, the first information may include the location and/or bandwidth of the transmit frequency band in the first sub-channel, and/or the location and/or bandwidth of the guard band. Among them, the transmission band can be used for transmission, but the guard band cannot be used for transmission. The bandwidth of the transmit frequency band may refer to the size of the transmit frequency band. For example, the bandwidth of the transmit frequency band may be 5 MHz. The position of the transmit frequency band may include the start position and the end position of the transmit frequency band. For example, the position of the transmit frequency band may include the start position of the transmit frequency band being 20 MHz and the end position being 30 MHz. The location and/or bandwidth of the guard band have a similar meaning. For example, the transmission frequency band and guard frequency band in sub-channel 1 (equivalent to the first sub-channel) may be as shown in Figure 9.

The position and/or bandwidth of the guard band carried in the first information may be the position and/or bandwidth of the single-sided guard band, that is, the position and/or bandwidth of the guard band on the left or right side of the transmit frequency band as shown in Figure 9 . This helps reduce the data carried by the first information and saves transmission resources.

Further, in order to simplify the reporting of the terminal equipment, the optional guard band position and/or bandwidth of the terminal equipment may also be predefined. For example, for a 20MHz sub-channel, the bandwidth of the optional single-sided guard band (single-sided refers to each side) can be predefined as {1MHz, 2MHz, 3MHz}, etc. The terminal device can select specific values to report.

Similarly, the location and/or bandwidth of the optional transmission frequency band of the terminal device can also be predefined. For example, for a 20MHz sub-channel, the bandwidth of the optional transmission frequency band can be predefined as {10MHz, 15MHz, 20MHz}, etc. The terminal device can select specific values to report.

Accordingly, before S810, the terminal device may determine the transmission frequency band and/or the guard frequency band in the first sub-channel. For example, the terminal device may determine the location and/or bandwidth of the transmission frequency band and/or the location and/or bandwidth of the guard frequency band based on the out-of-band leakage signal strength indicator of the first sub-channel. The out-of-band leakage signal strength indicator will be introduced in detail in subsequent embodiments, and will not be described in detail here.

In some implementations, the first information may also include a power backoff value and/or a maximum transmit power capability on the first subchannel. The power backoff value may refer to the value by which the transmission power is reduced. For example, the power backoff value of subchannel 1 (equivalent to the first subchannel) can be as shown in Figure 11. Alternatively, the maximum transmit power capability may be represented by the maximum transmit power on the first sub-channel.

Accordingly, before S810, the terminal device may determine the power backoff value and/or the maximum transmit power capability. For example, the terminal device may determine the power backoff value and/or the maximum transmit power capability value according to the out-of-band leakage signal strength indicator of the first sub-channel.

The out-of-band leakage signal strength index of the first sub-channel may refer to the strength index of the out-of-band leakage signal generated by the first sub-channel. Optionally, the out-of-band leakage signal strength indicators may be different in different areas in a sub-channel (or channel). For example, the out-of-band leakage signal strength index generated by sub-channel 1 can be shown as a dotted line in Figure 11. In different areas in sub-channel 2, the out-of-band leakage signal strength index is different.

Optionally, the first channel may also include a second sub-channel in addition to the first sub-channel. The second sub-channel may be in transmitting state.

In some implementations, the first information may also include the out-of-band leakage signal strength indicator of the second sub-channel and/or the out-of-band leakage signal interference information of the second sub-channel. The out-of-band leakage signal interference information may refer to the signal strength of the out-of-band leakage signal generated by the second sub-channel measured by the terminal device.

After S810, method 800 may also include steps S820 and S830, specifically as follows:

S820: The network device determines the target communication resource on the first sub-channel according to the first information.

S830: The network device sends instruction information to the terminal device. The indication information is used to indicate the target communication resource. The indication information may be the following second information, third information or fourth information.

For example, depending on the content contained in the first channel, S820 and S830 can be implemented in the following ways.

Method 1: Interference avoidance based on guard band

After receiving the first information, the network device may determine the target resource in the first sub-channel according to the location and/or bandwidth of the transmission frequency band in the first sub-channel and/or the location and/or bandwidth of the guard band. The target resource may include one or more RBs. For example, assuming that the bandwidth of the subchannel is 20MHz, after receiving the first information, the network device can determine that it can only configure the transmission signal of the terminal device within the remaining 10MHz range in the 20MHz subchannel; or, the terminal The device can also directly indicate that its available transmit frequency band size within the 20MHz sub-channel is 10MHz.

Further, the network device can send the second information to the terminal device. The second information may be used to indicate the target resource.

After receiving the second information, the terminal device may communicate with the network device on the first sub-channel using the target resource.

It can be seen that in method 1, the corresponding guard band position and/or bandwidth and the transmit frequency band position and/or bandwidth are determined according to the maximum transmit power capability of the terminal device.

Method 2: Interference avoidance based on transmit power control

After receiving the first information, the network device may determine the target transmit power on the first sub-channel according to the power backoff value and/or the maximum transmit power capability. The power backoff value may use the power level of the terminal device as a reference value to indicate the backoff value compared to its own power level. For example, the power backoff value can be 1dB, 2dB, 3dB, etc. The maximum transmit power capability can indicate the transmit power of the terminal. For example, the maximum transmit power can be 18dBm, 20dBm, 23dBm, etc.

Optionally, the target transmission power may be obtained by subtracting the power backoff value from the transmission power of the terminal device. Optionally, the target transmission power may not exceed the maximum transmission power value capability.

Further, the network device can send third information to the terminal device. The third information may be used to indicate the target transmit power on the first sub-channel.

After receiving the third information, the terminal device may communicate with the network device on the first sub-channel according to the target transmission power.

It can be seen that in method 2, the protection requirements for sub-channels are met by limiting the transmission power of the terminal while maintaining the maximum transmission frequency band of the terminal equipment. That is, when the out-of-band leakage signal strength index of the terminal device outside the transmission frequency band is determined, the corresponding out-of-band leakage signal strength index requirement can be met by reducing the transmission power.

Method 3: Interference avoidance based on reception resource set division

After receiving the first information, the network device may determine the target frequency region in the first sub-channel according to the out-of-band leakage signal strength indicator and/or the out-of-band leakage signal interference information. Optionally, the network device may determine the target frequency region in the first sub-channel according to the downlink signal strength corresponding to the terminal device, the out-of-band leakage signal strength indicator and/or the out-of-band leakage signal interference information. For example, as shown in Figure 12, if the out-of-band leakage signal strength indicator indicates that the signal strength in area 2 is 10dBm and the corresponding downlink signal strength of the terminal device is 15dBm (15dBm is greater than 10dBm), the network device can determine area 2 as the target frequency area .

As shown in Figure 12, the out-of-band leakage signal of sub-channel 1 falls into the interior of sub-channel 2, showing a gradually decreasing trend (the corresponding indicator may also show a gradually decreasing trend, such as the stepped dotted line in Figure 12). Correspondingly, the interior of sub-channel 2 can be divided into area 1 where ion channel 1 is relatively close, area 3 where ion channel 1 is relatively far away, and area 2 in the middle.

For ease of understanding, the coverage locations of cells can be distinguished, as shown in Figure 13, which can include central locations, sub-central locations, edge locations, etc. Among them, the downlink signal strength at the center position (the terminal equipment) is very strong and the anti-interference ability is the strongest; the downlink signal strength at the edge position is the weakest and the anti-interference ability is the worst; the sub-center position is in the middle.

Combining the above-mentioned division of cell coverage locations and the regional division of sub-channel 2 frequency domain, the following correspondence can be obtained:

Frequency area 1 has the strongest interference. In order to reduce the impact of interference, it is more suitable for areas where sub-channel 2 downlink received signals are relatively strong, such as the center area of the cell. Frequency area 3 has the weakest interference and can be used within the cell. Any location, including cell edge locations that are sensitive to interference; frequency area 2 can be applied to central and sub-central locations within the cell.

Through the division and combined application of this frequency area (interference strength) and cell location (downlink useful signal strength), the frequency area with strong interference can be allocated to the terminal equipment in the center with strong downlink signal, and the frequency area with weak interference can be allocated to the terminal equipment in the center with strong downlink signal. More are allocated to terminal equipment at the edge of cells where downlink signals are weak. In this way, all terminals in sub-channel 2 can finally have good anti-interference capabilities.

Further, the network device may send fourth information to the terminal device. The fourth information may be used to indicate the target frequency region in the first sub-channel. For example, as shown in FIG. 12 , subchannel 2 (corresponding to the first subchannel) is divided into multiple areas (frequency areas), and the target frequency area may be area 2.

After receiving the fourth information, the terminal device may communicate with the network device on the first sub-channel through the target frequency region.

In the above method 3, considering that the out-of-band leakage of the terminal equipment can only be reduced but not eliminated, and the closer the out-of-band leakage is to the transmitting frequency band, the stronger the useless radiation, the out-of-band leakage is reduced by fully scheduling the resources in the sub-channel. Impact.

In the embodiment of the present application, the out-of-band leakage signal strength indicator may be predefined; or the out-of-band leakage signal strength indicator is determined by the terminal device from multiple candidate out-of-band leakage signal strength indicators sent by the network device, for example, When a network device configures a sub-channel, it sends multiple candidate out-of-band leakage signal strength indicators to the end device. As shown in Figure 10, the out-of-band leakage signal strength indicator can indicate the signal strength indicator of the out-of-band leakage signal. Of course, (one) out-of-band leakage signal strength indicator may indicate out-of-band leakage signal strength indicators for different areas in the sub-channel. For example, as shown in Figure 12, the out-of-band leakage signal strength indicators of different areas in sub-channel 2 are different.

You can predefine indicator 1 (out-of-band leakage signal strength indicator) corresponding to the sub-channel bandwidth of 5 MHz, pre-defined indicator 2 to correspond to the sub-channel bandwidth of 10 MHz, and pre-defined indicator 3 to correspond to the sub-channel bandwidth of 20 MHz. Then, the terminal equipment can adjust the sub-channel bandwidth according to different sub-channel bandwidths. Determine the out-of-band leakage signal strength indicator; alternatively, the network device can also send indicator 1, indicator 2, and indicator 3 (that is, multiple candidate out-of-band leakage signal strength indicators) to the terminal device, and then the terminal device can select out-of-band leakage from them. Signal strength indicator.

Optionally, the out-of-band leakage signal strength indicator may include: absolute power strength and/or relative power strength.

The absolute power strength may refer to the power strength value of the out-of-band leakage signal in the first sub-channel. For example, when the power density is used as the indicator, the out-of-band leakage signal strength indicator can be -50dBm/MHz; when the total power of the out-of-band leakage signal is used as the indicator, the out-of-band leakage signal strength indicator can be -30dBm.

The relative power strength may refer to the ratio or difference between the power strength of the out-of-band leakage signal and the transmit power on the first sub-channel. Among them, the linear value can be a ratio value, and the dB value can be a difference value. For example, when using power density as the indicator, assuming that the out-of-band leakage signal strength indicator is no less than 30dB, this means that the leakage signal power density of the terminal equipment in sub-channel 2 needs to be lower than the transmit signal power density of the terminal equipment in sub-channel 1 At least 30dB or more.

Among them, the power density can be the average power density, that is, the ratio of total power to total bandwidth. For example, the power intensity of the out-of-band leakage signal may include: a ratio of the power intensity of the out-of-band leakage signal to other bandwidths in the first sub-channel except the first sub-channel. The transmit power may include: a ratio of the transmit power to the bandwidth of the first sub-channel, and/or a ratio of the transmit power to the bandwidth of the transmit frequency band in the first sub-channel.

Alternatively, the power density can also be absolute power density, that is, the power intensity per integration bandwidth (for example, per 1 MHz). For example, the power intensity of the out-of-band leakage signal may include: the power intensity of the out-of-band leakage signal on each integrated bandwidth in other bandwidths in the first sub-channel except the first sub-channel. The transmit power may include: a power intensity of the transmit power on each integrated bandwidth in the bandwidth of the first sub-channel.

Furthermore, an activation and deactivation mechanism for interference avoidance can be introduced. For example, if the network device configures sub-channel 1 for the terminal, but there is no sub-channel 2 terminal device in the current area where the terminal device works, then the network device can instruct the terminal device to deactivate (disable) the interference avoidance mechanism, that is, for the terminal device All frequency bands within sub-channel 1 can be used for transmission, and the transmission power can reach full power, etc.

The network device instructs the terminal device to activate or deactivate in the following ways:

For example, the network device may send the fifth information to the terminal device. The fifth information may be used to activate the above interference avoidance mechanism, or the fifth information may be used to deactivate the above interference avoidance mechanism. For example, the fifth information may be used to trigger the terminal device to report the first information.

In some implementations, if the network device configures an out-of-band leakage signal strength indicator for the terminal device, it may indicate that the interference avoidance mechanism is activated; if the out-of-band leakage signal strength indicator is not configured, it may indicate that the interference avoidance mechanism is not activated. That is to say, the fifth information may include the out-of-band leakage signal strength indicator sent by the network device. Alternatively, the network device can also display an instruction to the terminal device to activate or deactivate the interference avoidance mechanism when the out-of-band leakage signal strength indicator is configured.

In the above method 3, the terminal device needs to report the out-of-band leakage signal strength indicator and/or the out-of-band leakage signal interference information to the network device, so that the network device can determine the target frequency region in the first sub-channel. However, in this embodiment of the present application, the network device can also directly determine the target frequency region in the first sub-channel based on the predefined or preconfigured out-of-band leakage signal strength indication without the need for the terminal device to report.

The interference avoidance process in the above-mentioned Mode 1 and Mode 2 will be illustrated below with reference to FIG. 14 and FIG. 15 .

The configuration information may be used to configure the bandwidth and/or location of the subchannel, etc. The configuration information can carry out-of-band leakage signal strength indicators.

S1430: The terminal device reports the transmission frequency band and/or guard frequency band to the network device.

The terminal device may report the location and/or bandwidth of the transmission frequency band in the sub-channel, and/or the location and/or bandwidth of the guard band.

S1440: The network device configures the target RB resource in the sub-channel for the terminal device.

The network device may determine the target RB resource in the sub-channel according to the location and/or bandwidth of the transmission frequency band in the sub-channel and/or the location and/or bandwidth of the guard band.

S1510: The terminal device reports sub-channel capabilities to the network device.

S1520: The network device sends configuration information to the terminal device.

The configuration information can be used to configure the bandwidth and/or location of the subchannel, etc. The configuration information can carry out-of-band leakage signal strength indicators. For example, the network device may send multiple candidate out-of-band leakage signal strength indicators to the terminal device when configuring the sub-channel.

S1530: The terminal device reports the maximum transmit power capability to the network device.

The maximum transmit power capability can be expressed by a maximum transmit power value or a power backoff value. The power backoff value may use the power level of the terminal device as a reference value to indicate the backoff value compared to its own power level. For example, the power backoff value can be 1dB, 2dB, 3dB, etc. The maximum transmit power value can indicate the transmit power of the terminal. For example, the maximum transmit power can be 18dBm, 20dBm, 23dBm, etc.

S1540: The network device schedules the target transmission power in the sub-channel for the terminal device.

The target transmit power does not exceed the maximum transmit power capability. For example, the target transmission power may be obtained by subtracting the power backoff value from the maximum transmission power value of the terminal device.

S1550: The terminal device communicates with the network device according to the target transmission power.
