Background
In the new air interface (5-Generation New Radio,5G NR) of the fifth generation mobile communication technology, since the frequency band of the terminal device supporting the millimeter wave (for example, frequency range 2, FR 2) is relatively high, the propagation attenuation of the terminal device supporting the FR2 is generally more than 26GHz, and in order to maintain continuous connection with the cellular network, the terminal device is often connected to the network through a low frequency band (for example, frequency range 1, FR 1) (a signal with a frequency less than 7G Hz) at the same time. In this way, when the terminal device supporting FR2 works normally, it will always keep a radio connection in the low frequency band and a radio connection in the millimeter wave band at the same time. In practical communication, since the carrier frequency of the FR2 signal is high, it is often necessary to introduce an intermediate frequency signal. Specifically, the first step is to mix the baseband signal to be shifted with an intermediate frequency signal, and shift the baseband signal to an intermediate frequency (the frequency of the intermediate frequency signal); the second step is to mix the intermediate frequency signal containing the baseband signal and further shift it to the frequency of the target FR 2. However, since an intermediate frequency signal is introduced, the intermediate frequency signals of FR1 and FR2 will generate self-interference, and how the terminal device measures the self-interference is a problem to be solved.

It should be appreciated that within a wireless terminal for cellular communication, a wide variety of self-interfering signals may be generated: i.e. signals generated/transmitted internally by the terminal, interfere with the normal reception by the terminal.
In some embodiments of the present application, self-interference signals may be classified into three categories based on their source.
The first type of self-interference signal may be harmonic or intermodulation interference generated by one or several transmitted signals of the communication system. For example, it may be harmonic or intermodulation interference generated by one or several transmitted signals of a cellular communication system. Such self-interference signals are a relatively significant class of interference signals in cellular communication systems. For example, the first type of self-interference signal exists when the transmission signal and the reception signal inside the terminal device directly have a frequency multiplication relationship, such as 2 times, 3 times, 4 times, and the like. In general, the first type of self-interference signal is severe when the frequency multiplication relation is less than or equal to 5.
The second type of self-interference signal originates from interference between different wireless communication modules within the handset, for example, between wireless fidelity (WiFi) signals and cellular signals.
The third type of self-interference signals mainly originate from electromagnetic waves generated by some active electronic devices inside the terminal. For example, electromagnetic waves generated by devices such as a display screen of the terminal device, a memory read operation of the terminal device, a camera and an electric motor of the terminal device, and the like. The frequency range of the electromagnetic wave can be tens to hundreds of MHz, and when the harmonic wave falls on the cellular frequency band or intermodulation is generated between the harmonic wave and a transmitting signal of the cellular frequency band, the electromagnetic wave can interfere with the receiving of the cellular frequency band.
In the embodiment of the present application, when the terminal device supporting millimeter wave communication performs self-interference measurement, the terminal device may be at least one of the first type self-interference signal, the second type self-interference signal, and the third type self-interference signal. For example, when the self-interference signal of the first type is aimed at, the terminal equipment carries out self-interference measurement aiming at the self-interference signal of the first type.
With the advent of new air interface (5-Generation New Radio,5G NR) systems of the fifth generation mobile communication technology, terminal devices (e.g., handsets) supporting millimeter wave (e.g., frequency range 2, fr 2) communication have emerged. Since the frequency bands of the mobile phone supporting FR2 are relatively high, the propagation attenuation is serious at more than 26GHz, for example, 28GHz,31GHz, and even 40GHz, in order to keep continuous connection with the cellular network, the mobile phone is often connected with the network through a low frequency band (for example, frequency range 1, FR 1) (a signal with a frequency less than 7 GHz). Therefore, when the mobile phone supporting the FR2 works normally, the wireless connection of a low frequency band and the wireless connection of a millimeter wave frequency band are always kept at the same time. Taking the commonly used low frequency band of 3.5GHz as an example, there is a relatively large multiple relation (> 5) compared with the millimeter wave frequency band (above 26 GHz), so that serious self-interference should not occur between their direct transceiving signals. However, due to the specificity of the millimeter wave band implementation, self-interference between high and low frequency signals does sometimes exist.
A general radio signal is first generated on a baseband, and the baseband generated signal is mixed with a radio frequency signal having the same frequency as a target carrier, and as a result, the baseband signal is moved to the target carrier. This is the basic principle of mixing radio signals. For the above-mentioned FR1 signal, basically, this principle is adopted to realize the movement of the baseband signal to the target carrier (radio frequency signal). But for FR2 signals the problem is more complex. The carrier frequency of the FR2 signal is very high and above 26GHz, but the baseband signal frequency for carrying information is generally between tens MHz and hundreds MHz, if the baseband signal corresponding to FR2 is directly moved to the carrier frequency above 26GHz by mixing, the frequency difference between the two is too large, and the problem of difficulty in realization exists. Thus, in practice this is solved by two steps: firstly, mixing a baseband signal to be moved and an intermediate frequency signal, and moving the baseband signal to an intermediate frequency (the frequency of the intermediate frequency signal); the second step is to mix the intermediate frequency signal containing the baseband signal and further shift it to the frequency of the target FR 2. The core is that an intermediate frequency signal is introduced, and the intermediate frequency signal, a baseband signal and the target frequency of FR2 are not particularly large in frequency difference. For millimeter wave signals above 26GHz, this intermediate frequency signal is possible between 8GHz and 12 GHz.
However, the introduction of this intermediate frequency signal also results in the generation of self-interference. The intermediate frequency signal of 8 GHz-12 GHz may have a frequency multiplication relationship with a plurality of FR1 signals, thereby generating self-interference.
Specifically, when the transmission signal of FR1 and the intermediate frequency signal of FR2 have a frequency multiplication relationship, two kinds of self-interference are generated:
1. the harmonic wave of the transmitting signal of the FR1 interferes with the intermediate frequency signal of the FR2, so that the transmitting signal of the FR1 interferes with the baseband receiving of the FR 2;
2. harmonics of the FR1 receive signal are mixed with the FR2 intermediate frequency transmit signal, such that the FR2 transmit signal interferes with the FR1 baseband reception.
The embodiments of the present application will address this problem of self-interference between FR1 and FR2 signals due to the introduction of FR2 intermediate frequency signals.
It should be noted that, in the embodiment of the present application, the terminal device supporting FR2 needs to use an array antenna to implement transmission and/or reception of the millimeter wave signal. In a terminal implementation, a group of antennas and a Radio Frequency (RF) front end (front end) device are integrated into a module (module), and typically, such a module contains 4 to 8 antennas and corresponding RF devices. In order to enable the beam formed by the array antennas in the terminal device (e.g. the handset) to be directed in various directions, a plurality of sets of array antennas are often installed in the handset, and the sets of array antennas are installed in different positions of the handset. Such as: a group of array antennas are respectively arranged at the top and the bottom of the mobile phone; or four sides of the mobile phone are provided with a group of array antennas. In practical use, these array antenna groups often operate in a time division multiplexing (Time Division Multiplexing, TDM) mode, i.e., only one array antenna group is in operation at a time. The advantage of this arrangement is that shielding, for example, the position of the hand holding the mobile phone may be shielded from a certain array antenna group, and the terminal may switch to another group of non-shielded array antennas to transmit and receive FR2 signals.
The strength of the self-interference of the FR1 signal and the FR2 signal is related to the location of the module (including the rf front-end device corresponding to the array antenna combination) that transmits/receives the FR2 signal. On the other hand, FR1 signals of different frequency bands may use different radio frequency devices, which are also located differently. Thus, the relative position of the receiving/transmitting FR1/FR2 signal devices/modules may affect the strength of the self-interference, and in general, the farther the receiving/transmitting FR1/FR2 signal devices/modules are, the weaker the self-interference. However, since the frequency of the FR2 signal is high, even if the intermediate frequency signal (8 GHz to 12 GHz) of the FR2 signal is considered, the frequency is relatively high, and the placing position of the mobile phone, the hand holding posture of the mobile phone by a hand, and the like may have an influence on the intensity of the self-interference. Therefore, in order to evaluate the magnitude of the influence of self-interference between FR1 and FR2 signals more accurately, a self-evaluation/measurement procedure of the terminal device needs to be introduced, and a module of FR2 that generates less self-interference is selected to be used for transmission and reception of the FR2 signals.
It should be appreciated that the self-interference between FR1 and FR2 signals can be split into two directions:
1. interference of the transmission of the FR1 signal to the FR2 received signal;
2. The transmission of the FR2 signal interferes with the reception of the FR1 signal.
From the nature of self-interference generation, the location of the modules of FR2 has the same effect on self-interference in both directions. In other words, for the interference of the transmission of the FR1 signal to the reception of the FR2 signal, one FR2 module is selected, and if the effect of the self-interference is minimal, the same FR2 module can also produce the least self-interference for the interference of the transmission of the FR2 signal to the reception of the FR1 signal. This property makes it possible to measure only one direction of the self-interference in the two directions, thus increasing the scheduling flexibility of the network device (the network device can configure whether to transmit FR1 signals or FR2 signals according to the actual situation), and reducing the measurement time of the terminal.
The following describes how a terminal device supporting millimeter wave communication implements self-interference measurement in connection with a specific embodiment.
Fig. 2 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, as shown in fig. 2, the method 200 is applied to a terminal device supporting millimeter wave communication, and the terminal device includes at least one first module for receiving and/or transmitting millimeter wave signals, the method 200 may include:
S210, the terminal device sends first information to the network device, where the first information includes at least one of the following information:
frequency band combinations of self-interference are generated, the intermediate frequency used by the first module, and the number of the first modules.
It should be noted that, a set of antennas and a Radio Frequency (RF) front-end device for receiving and/or transmitting millimeter wave signals are integrated into the first module, and the first module typically includes 4 to 8 antennas and corresponding radio frequency devices.
Alternatively, the intermediate frequency used by the first module may be within 8GHz to 12GHz, for example, 10GHz.
It should be noted that, the terminal device reports the intermediate frequency used by the first module, so that the network device can determine which FR1 frequency bands will interfere with which FR2 frequency bands according to the intermediate frequency reported by the terminal device.
Optionally, in an embodiment of the present application, the frequency band combination includes at least one of the following combinations:
at least one low frequency band for uplink transmission and at least one millimeter wave band for downlink reception;
at least one low frequency band for downlink transmission and at least one millimeter wave band for uplink reception;
At least one millimeter wave band for uplink transmission and at least one low frequency band for downlink reception;
at least one millimeter wave band for downstream transmission and at least one low frequency band for upstream reception.
For example, n78 and n260, where n78 is the frequency band of FR1 and n260 is the frequency band of FR 2.
It should be understood that the terminal device reports the number of the first modules, which helps the network device to configure appropriate measurement parameters.
Optionally, in the embodiment of the present application, the terminal device may also send the first information to the network device according to a requirement of the network device. For example, the network device may request the terminal device to report the interference-generating band combination or the intermediate frequency used by the first module.
Alternatively, in the embodiment of the present application, the terminal device may perform self-interference measurement based on the configuration of the network device.
Specifically, the terminal device receives first configuration information sent by the network device, where the first configuration information is used to configure a self-interference measurement parameter, and perform self-interference measurement according to the self-interference measurement parameter.
It should be noted that, after receiving the first information, the network device determines the first configuration information according to the first information, and sends the first configuration information to the terminal device.
Optionally, in an embodiment of the present application, the self-interference measurement parameter includes:
the starting position and the measurement duration of each measurement period in the time domain of the at least one measurement period, and at least one of a known transmission signal, a time domain resource, a frequency domain resource, and a transmission power corresponding to the each measurement period.
Optionally, the starting position of each measurement period in the time domain includes a time slot identifier and a symbol identifier where the starting position is located.
Optionally, the time domain resource corresponding to each measurement period includes a time slot identifier and a symbol identifier in a time domain, and the frequency domain resource corresponding to each measurement period includes a subcarrier identifier of a physical resource block (physical resource block, PRB) identifier in a frequency domain.
Optionally, the number of the at least one measurement period is the same as the number of the at least one first module.
In the embodiment of the present application, self-interference between FR1 (low frequency band) and FR2 (millimeter wave frequency band) signals can be classified into two categories:
the first category, interference of the transmission of FR1 signals to the reception of FR2 signals;
the second type, the transmission of the FR2 signal, interferes with the reception of the FR1 signal.
In the self-interference measurement, only the above-mentioned type of self-interference needs to be measured, for example, the interference of the transmission of the FR1 signal to the reception of the FR2 signal is measured, so that the first module generating the smallest self-interference can be identified, and therefore, the network device can indicate which type of self-interference needs to be performed by the terminal device.
Optionally, in the embodiment of the present application, if interference of the low-frequency band transmission signal on the millimeter-wave band reception signal needs to be measured, the at least one first module of the terminal device measures the received signal power or strength in the at least one measurement period respectively.
Optionally, in the embodiment of the present application, if interference of the millimeter wave band transmission signal on the low frequency band reception signal needs to be measured, the terminal device measures signal power or strength from different first modules in the at least one measurement period respectively. It should be noted that, the receiver in the terminal device for receiving and/or transmitting the low-band signal may measure the signal power or the strength from the different first modules during the at least one measurement period, respectively.
Alternatively, as an embodiment one, the network device instructs the terminal device to measure interference of the transmission of the FR1 signal with the reception of the FR2 signal. The network device needs to configure the corresponding time domain resource and frequency resource on the FR1 frequency band, and the transmitting power to the terminal device. The terminal device transmits a known signal, such as a sounding reference signal (Sounding Reference Signal, SRS), at a given power on the time domain resources and frequency resources configured by the network device. The network device also needs to configure the terminal device with corresponding measurement period information over which a plurality of FR2 modules (modules for receiving and/or transmitting millimeter wave signals) of the terminal device alternately measure the received signal power/strength. The network device does not schedule the downlink signal of FR2 over these measurement periods, so the signal power received by the FR2 module (the first module described above) over these measurement periods is the interference power from the FR1 signal. The terminal device can know which FR2 module brings the minimum self-interference by comparing the interference power measured by different FR2 modules. The measurement periods configured by the network device may be in symbols (symbols), so the network device needs to indicate the duration of each measurement period, such as: for several symbol. The network device may configure the number of measurement periods according to the number of FR2 modules reported by the terminal device. For example, a terminal device has 4 FR2 modules, and the network device may configure the terminal device with 4 measurement periods, where the terminal device performs measurements with different FR2 modules in each measurement period. It should be noted that for each measurement period of the FR2 module, a corresponding known transmit signal on the FR1 band is required. The network device can configure the measurement period and the transmission signal of FR1 in pairs. For example, the network device may configure the self-interference measurement parameters as shown in table 1 below, so that the terminal device performs self-interference measurement based on such self-interference measurement parameters.
TABLE 1
Figure GDA0002945256590000121
It should be noted that, for the start position of the measurement period in the time domain, a slot number (slot number) and a symbol number (or identifier) need to be specified. The configuration of the transmission signals of FR1 corresponding to different measurement periods needs to indicate specific positions of the time domain resources and the frequency domain resources, including slot numbers (or identifiers) in the time domain, symbol numbers (or identifiers) in the frequency domain, PRB numbers (or identifiers) in the frequency domain and subcarrier numbers (or identifiers).
Alternatively, as a second embodiment, the network device instructs the terminal device to measure interference of the transmission of the FR2 signal with the reception of the FR1 signal. The network device needs to configure time domain resources and frequency resources on multiple sets of FR2 frequency bands, and corresponding transmitting power to the terminal device. The terminal device transmits a known signal, such as SRS, at a given power using different FR2 modules (modules for receiving and/or transmitting millimeter wave signals) alternately on time domain resources and frequency resources configured by the network device. The network device also needs to configure the terminal with corresponding measurement period information, and the receiver of the corresponding frequency band of FR1 of the terminal device sequentially measures the received signal power/strength over these measurement periods. The network device does not schedule the downlink signal of FR1 over these measurement periods, so the signal power received by the receiver of FR1 over these measurement periods is the interference power from the FR2 signal. The terminal device can know which FR2 module brings the smallest self-interference by comparing the interference power measured in different measurement periods. The measurement periods configured by the network device may be in symbols, so the network device needs to indicate the duration of each measurement period, such as: for several symbol. The network device may configure the number of measurement periods according to the number of FR2 modules reported by the terminal device. For example, a terminal device has 4 FR2 modules, and the network device may configure this terminal device with 4 measurement periods, during each of which the terminal device measures interference signals from different FR2 modules. It should be noted that for each measurement period, a corresponding given transmission signal on the FR2 band is required. The network device can configure the measurement period and the transmission signal of FR2 in pairs. For example, the network device may configure the self-interference measurement parameters as shown in table 2 below, such that the terminal device performs self-interference measurement based on such self-interference measurement parameters.
TABLE 2
Figure GDA0002945256590000131
It should be noted that, for the start position of the measurement period in the time domain, a slot number (slot number) and a symbol number (or identifier) need to be specified. The configuration of the transmission signals of FR2 corresponding to different measurement periods needs to indicate specific positions of the time domain resources and the frequency domain resources, including slot numbers (or identifiers) in the time domain, symbol numbers (or identifiers) in the frequency domain, PRB numbers (or identifiers) in the frequency domain and subcarrier numbers (or identifiers).
Optionally, in this embodiment of the present application, the terminal device switches preferentially to the first module corresponding to the measured minimum signal power or strength.
Optionally, in the embodiment of the present application, the terminal device may also report the measurement result to the network device.
Specifically, the terminal device sends second information to the network device, where the second information is used to indicate the measured minimum or maximum signal power or intensity, or is used to indicate a measurement period identifier corresponding to the measured minimum or maximum signal power or intensity, or is used to indicate a time domain/frequency domain position of a millimeter wave transmission signal corresponding to the measured minimum or maximum signal power or intensity.
It should be noted that, the terminal device may actively send the second information to the network device, or the terminal device may send the second information to the network device under the requirement of the network device.
For example, the terminal device receives second configuration information sent by the network device, where the second configuration information is used to instruct the terminal device to report the second information, and in response to the second configuration information, the terminal device sends the second information.
It will be appreciated that in general it is the terminal device implementation which FR2 module is employed by the terminal device for transmitting and/or receiving FR2 signals, without reporting to the network device. Sometimes reporting to the network device is advantageous for the network device to make a reasonable scheduling decision. The terminal device may report its measured minimum and maximum interference strengths to the network device, which are measured during the measurement period. The terminal device may also report the FR2 module corresponding to the minimum and maximum interference intensity, but the position of the FR2 module of the terminal device is not visible to the network device, so for the result obtained by measuring with the FR2 module (the interference of the emission of the FR1 signal to the reception of the FR2 signal), the terminal device reports the number of the measurement period corresponding to the minimum/maximum interference intensity; for the results obtained by measuring the signals transmitted by different FR2 modules (interference of the transmission of the FR2 signal to the reception of the FR1 signal), the terminal device reports the time domain/frequency position of the FR2 transmission signal corresponding to the minimum/maximum interference strength. If the network device configures the measurement period and the parameters of the measured transmission signal in pairs as described in table 1 and/or table 2, the terminal device may also report the number of the measurement period for the result obtained by measuring the transmission signal of different FR2 modules (interference of the transmission of the FR2 signal to the reception of the FR1 signal). The reporting of the network device by the terminal device may be made under the requirement of the network device.
Therefore, in the embodiment of the application, the terminal equipment supporting millimeter wave communication can measure the self-interference intensity, so that the first module for receiving and/or transmitting the millimeter wave signal with smaller self-interference can be selected to receive and transmit the millimeter wave signal, and the communication quality is improved.
