Detailed Description

Technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic diagram of an application scenario of an embodiment of the present application.

As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air. Multi-service transport is supported between terminal device 110 and network device 120.

It should be understood that the embodiment of the present application is only illustrated as the communication system 100, but the embodiment of the present application is not limited thereto. That is to say, the technical solution of the embodiment of the present application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, a Time Division Duplex (TDD) System, a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a New Radio (NR), a future 5G System, or the like.

Taking a 5G system as an example, the technical scheme of the embodiment of the present application may be applied to a Long Term Evolution (LTE) coverage of a wide area and an islanding coverage mode of NR. Moreover, a large amount of LTE is deployed below 6GHz, and the spectrum below 6GHz available for 5G is rare. NR must therefore be studied for spectrum applications above 6GHz, with limited high band coverage and fast signal fading. Meanwhile, in order to protect the early LTE investment of a mobile operator, a work mode of tight connection (light interworking) between LTE and NR is provided.

The main application scenarios of 5G include: enhanced Mobile Ultra wide band (eMBB), Low-Latency and high-reliability Communication (URLLC), and massive machine type Communication (mMTC). Among them, the eMBB aims at users to obtain multimedia contents, services and data, and its demand is rapidly increasing. As the eMBB may be deployed in different scenarios. For example, indoor, urban, rural, etc. have relatively large differences in capabilities and needs, so that they cannot be analyzed in general and can be combined with detailed analysis of specific deployment scenarios. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

In addition, since the complete 5G NR coverage is difficult to obtain, the network coverage of the embodiment of the present application may adopt a Long Term Evolution (LTE) coverage of a wide area and an islanding coverage mode of NR. Meanwhile, in order to protect the mobile operator from LTE investment in the early stage, a tight connection (light interworking) working mode between LTE and NR may be further adopted.

In particular, the technical solution of the embodiment of the present application may be applied to various communication systems based on non-orthogonal Multiple Access technologies, for example, a Sparse Code Multiple Access (SCMA) system, a Low Density Signature (LDS) system, and the like, and of course, the SCMA system and the LDS system may also be called other names in the communication field; further, the technical solution of the embodiment of the present application may be applied to a Multi-Carrier transmission system using a non-Orthogonal multiple access technology, for example, an Orthogonal Frequency Division Multiplexing (OFDM) using a non-Orthogonal multiple access technology, a Filter Bank Multi-Carrier (FBMC), a General Frequency Division Multiplexing (GFDM), a Filtered Orthogonal Frequency Division Multiplexing (F-OFDM) system, and the like.

Alternatively, the network device 120 may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) System or a Code Division Multiple Access (CDMA) System, or may be a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) System, and the network device 120 may also be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (Long Term Evolution, LTE) System. Alternatively, the Network device 120 may also be a Next Generation Radio Access Network (NG RAN), or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the Access Network device may be a relay station, an Access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, or a Network device in a Public Land Mobile Network (PLMN) for future evolution, or the like.

A terminal device arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal", or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; personal Communications Systems (PCS) terminals that may combine cellular radiotelephones with data processing, facsimile, and data Communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver.

Optionally, terminal-to-Device (D2D) communication may be performed between terminal devices 110.

Within a wireless terminal for cellular communication, a variety of self-interference signals may be generated: i.e., signals generated/transmitted within the terminal, may interfere with the normal reception by the terminal.

Fig. 1 illustrates a network device and a terminal device, and optionally, the communication system 100 may include a plurality of network devices and each network device may include other numbers of terminal devices within its coverage area, which is not limited to the implementation of the present application.

Optionally, the communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited thereto in the embodiments of the present application.

Optionally, the Uplink Channel in the embodiment of the present application may include a Physical Random Access Channel (PRACH), a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), and the like. The uplink Reference Signal may include an uplink Demodulation Reference Signal (DMRS), a Sounding Reference Signal (SRS), a phase tracking Reference Signal (PT-RS), and the like. The uplink DMRS can be used for demodulation of an uplink channel, the SRS can be used for measurement, uplink time-frequency synchronization or phase tracking of the uplink channel, and the PT-RS can also be used for measurement, uplink time-frequency synchronization or phase tracking of the uplink channel. It should be understood that, in the embodiment of the present application, an uplink physical channel or an uplink reference signal with the same name and different function as the above may be included, and an uplink physical channel or an uplink reference signal with the same name and different function as the above may also be included, which is not limited in the present application.

It should be understood that, in the embodiments of the present application, devices having a communication function in a network/system may be referred to as communication devices. Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 120 and a terminal device 110 having a communication function, and the network device 120 and the terminal device 110 may be the devices described above and are not described herein again; the communication device may also include other devices in the communication system 100, such as other network entities, for example, a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In the communication system 100 shown in fig. 1, when the terminal device 110 operates simultaneously on two or more carriers in different frequency bands, uplink signals of the carriers may interfere with downlink received signals of some carriers. For example, assuming that the terminal device 110 may operate on the carrier F1 and the carrier F2 at the same time, and the carrier F1 operates in the low frequency band and the carrier F2 operates in the high frequency band, three different types of mutual interference may exist, specifically, intermodulation interference, harmonic interference, and harmonic intermodulation interference.

For intermodulation interference, it is assumed that the frequency of the uplink carrier of F1 and the frequency of a certain-order Intermodulation (IM) signal of the uplink carrier of F2 overlap or partially overlap with the frequency of the downlink signal of a certain carrier F3. Carriers F1 and F2 constitute intermodulation interference to F3.

F3 may be either F1 or F2, or another carrier different from F1 and F2 (in this case, the terminal device 110 may operate on more than two carriers at the same time).

For example, assuming that the terminal device 110 is configured with a Band (Band)1 and a Band7 in an LTE carrier and 3400MHz-3800MHz in an NR carrier, if the uplink of the Band7 and the uplink of the NR are transmitted simultaneously, a 5 th-order intermodulation signal generated by the terminal device may affect the sensitivity of the downlink receiver of the Band 1.

For harmonic interference, assume that the frequency multiplication of the upstream carrier of F1 overlaps or partially overlaps with the downstream signal frequency of F2. Carrier F1 constitutes harmonic (harmonic) interference to F2.

For example, the 2 nd order harmonic range of 1710-. Then if the terminal device 110 performs LTE uplink transmission on band 3 and downlink reception on NR 3400 + 3800MHz at the same time, the 2 nd order harmonic may interfere with the sensitivity of the NR downlink receiver.

For harmonic intermodulation interference, it is assumed that the frequency multiplication of the downstream carrier of F1 overlaps or partially overlaps with the upstream signal frequency of F2 (and its neighboring frequencies). Carrier F2 constitutes harmonic intermodulation (harmonic cancellation) interference to F1.

For example, the 2 nd order harmonic range of the downlink 1805 + 1880MHz of the LTE Band 3 is 3610 + 3760 MHz. Then if the terminal device 110 performs LTE downlink reception on band 3 and performs uplink transmission on NR 3400-.

In the related art, a self-interference cancellation technique may be used to reduce intermodulation interference, harmonic interference, and harmonic intermodulation interference existing in the terminal device 110. However, since the cancellation effect of the self-interference cancellation technique depends on the internal implementation of the terminal device 110, it is important how to measure the cancellation effect of the self-interference cancellation technique in the actual communication process. Or, in the actual communication process, it is urgently needed to introduce a measurement for the self-interference cancellation technology to measure the cancellation effect of the terminal device 100 in the self-interference cancellation process.

The embodiment of the application provides a method for measuring the elimination effect of self-interference elimination.

Fig. 2 shows a schematic flow diagram of a method 200 of measuring interference according to an embodiment of the application, which method 200 may be performed by a terminal device. For example, it may be a terminal device as shown in fig. 1. The method 200 includes some or all of the following:

s210, the terminal device obtains a first measurement time interval.

S230, the terminal equipment carries out self-interference elimination in the first measurement time period, and measures the elimination effect of the self-interference elimination.

Namely, the terminal device measures the cancellation effect of the self-interference cancellation in the self-interference cancellation process in the first measurement period.

The first measurement period may include at least one time unit, wherein each of the at least one time unit may include at least one of:

symbols, slots, subframes, and frames.

The self-interference cancellation may refer to coupling or sampling a part of the transmission signal as a reference signal, applying corresponding gain, delay and phase adjustment to the reference signal, constructing a cancellation signal having the same power and the opposite phase as the actual self-interference signal, and finally implementing the destructive interference cancellation of the self-interference signal at the receiving end. This self-interference cancellation procedure is essentially a model that implements a self-interference reconstruction inside the terminal device.

It should be understood that the self-interference of the terminal device is not specifically limited in this embodiment of the application.

For example, in some embodiments of the present application, the self-interference signals may be classified into three categories according to their sources.

Therein, the first type of self-interference signal may be a harmonic or intermodulation interference generated by one or several transmit signals of the communication system. For example, it may be a harmonic or intermodulation interference generated by one or several transmission signals of the cellular communication system.

The second type of self-interference signal is derived from interference between different wireless communication modules inside the handset, for example, interference between a WiFi signal and a cellular signal.

The third type of self-interference signal originates mainly from electromagnetic waves generated by some active electronic devices inside the terminal. For example, a display screen of the terminal device, a memory reading operation of the terminal device, a camera of the terminal device, an electromagnetic wave generated by an electric motor, and the like. The frequency range of the electromagnetic wave can be dozens of MHz to hundreds of MHz, and when the harmonic wave falls on the cellular frequency band or the harmonic wave and the transmitting signal of the cellular frequency band are mutually modulated, the electromagnetic wave can generate interference on the reception of the cellular frequency band.

In this embodiment of the application, when the terminal device performs self-interference cancellation in the first measurement period, the terminal device may perform cancellation on at least one of the first self-interference signal, the second self-interference signal, and the third self-interference signal.

For example, the terminal device may measure a cancellation effect of the first type self-interference signal when cancelling the first type self-interference signal within the first measurement period.

A specific implementation of S210 is explained below.

Optionally, in some embodiments of the present application, the method 200 may further include:

the terminal equipment receives first indication information; the terminal equipment determines the time interval indicated by the first indication information as the first measurement time interval.

and the terminal equipment receives parameters used for self-interference elimination by the terminal equipment in the first measurement period.

The parameters include, but are not limited to, at least one of the following information:

combining frequency bands;

at least one interference type corresponding to the frequency band combination;

and the strength of the interference signal corresponding to each interference type.

Since the self-interference signal is interference generated by a transmission signal of one or a group of uplink frequency bands to one or a group of downlink signals, when the terminal device performs self-interference cancellation, it is necessary to specify a frequency band combination for the terminal device to perform self-interference cancellation.

For example, the band combination may be B3(1.8G) + n78 (3.5G).

For another example, the frequency band combination may be B8(0.9G) + B3 (1.8G).

In addition, since there may be one or more interferences for a specific frequency band combination, the terminal device needs to specify the type of interference to be targeted when performing self-interference cancellation.

For example, B3+ n78, there are harmonics and intermodulation interferences, so it is necessary to point out whether the interference type for which the frequency band combination corresponds is the single harmonic interference or the single intermodulation interference, and the frequency band combination corresponds to at least one interference type. The at least one interference type corresponding to the frequency band combination may be a sub-parameter under the frequency band combination.

After the network device configures at least one interference type corresponding to the frequency band combination for the terminal device, the network device may also schedule uplink signal transmission causing the at least one interference type, that is, the strength of the interference signal corresponding to the at least one interference type. The strength of the interference signal corresponding to the specific interference type may be a sub-parameter of at least one interference type corresponding to the frequency band combination.

The strength of the interference signal corresponding to the at least one interference type refers to the strength of the uplink signal causing the at least one interference type. For example, if it is a harmonic interference, it is the strength of the transmitted signal that causes the harmonic; if the interference is intermodulation interference, the respective intensities of two paths of uplink signals causing intermodulation. If there are both harmonics and intermodulation, the respective strength of the uplink signal on each path causing the interference is determined. After the terminal device learns the strength of the interference signal corresponding to the at least one interference type, the terminal device may calculate a self-interference cancellation effect according to the energy of the signal measured in the first measurement period.

Optionally, in some embodiments of the present application, the first measurement period includes at least one measurement period, and each measurement period corresponds to one of the at least one interference type.

In particular, various types of interference may be present in certain specific combinations of frequency bands.

For example, for B3+ n78, there is intermodulation and harmonic interference, and in order to enable the terminal device to more accurately measure intermodulation and harmonic interference, the network device may schedule measurement periods separately. That is, the network device schedules two measurement periods, one to calibrate the harmonic interference and the other to calibrate the intermodulation interference, respectively. When the harmonic interference is calibrated, only the transmitted signal of B3; when the intermodulation interference is calibrated, there are transmitted signals of B3 and n78 simultaneously.

Optionally, in some embodiments of the present application, the first measurement period includes one measurement period, and the one measurement period corresponds to the at least one interference type.

For example, for B3+ n78, where intermodulation and harmonic interference is present, the first measurement period scheduled by the network device comprises only the first measurement period. At this time, the network device needs to explicitly indicate the interference type for the one measurement period.

The specific implementation manner in which the terminal device obtains the first measurement period and the parameter corresponding to the first measurement period and used for the terminal device to perform self-interference cancellation through configuration of the network device is described in detail above, and the implementation manner in which the terminal device obtains the first measurement period through a request from the network device is described below.

the terminal equipment sends request information, and the request information is used for requesting the first measurement time interval; the terminal equipment receives response information of the request information, wherein the response information of the request information comprises information used for indicating the first measurement time interval.

For example, the request information is specifically used to request a network device to allocate the first measurement period satisfying a specific parameter to the terminal device, where the specific parameter includes a parameter for the terminal device to perform self-interference cancellation.

The specific parameters include, but are not limited to, at least one of the following information:

combining specific frequency bands;

the specific frequency band combination corresponds to a specific interference type; and

a strength of an interference signal corresponding to the particular interference type.

For example, the terminal device may request from the network device to provide a measurement period for each of the harmonics and intermodulation interference of the B3+ n78 band combination. Further, the transmission power of the interference signal corresponding to the harmonic and the intermodulation interference is the maximum transmission power. Assuming that the power level of the terminal equipment is 3, when the terminal equipment measures harmonic interference, the transmitting power of B3 is 23 dbm; when the terminal equipment measures intermodulation interference, the transmission power of B3 and n78 are each 20 dbm.

A specific implementation of S220 is described below.

Optionally, in some embodiments of the present application, there is no downlink signal of the terminal device in the first measurement period. Namely, when the terminal device performs self-interference elimination for the self-interference signal in the first measurement period, the terminal device prohibits receiving the downlink signal.

Thus, the terminal device may perform self-interference cancellation and measure the energy of the received signal during the first measurement period. Specifically, the terminal device measures energy of a signal received by the terminal device during a self-interference cancellation process performed in the first measurement period, where the energy of the signal received by the terminal device can indicate a cancellation effect of the terminal device during the self-interference cancellation process.

For example, the energy of the signal received by the terminal device when the terminal device does not perform self-interference cancellation in the first measurement period is a first value, the energy of the signal received by the terminal device when the terminal device performs self-interference cancellation in the first measurement period is a second value, and the terminal device may determine the cancellation effect of self-interference cancellation by comparing the second data with the first value.

In this embodiment of the present application, since only the interference signal exists and no downlink signal exists in the first measurement period, when the terminal device performs self-interference cancellation, in the first measurement period, the signal entering the terminal receiver should include the interference signal that is not completely cancelled and the background noise of the receiver itself. Therefore, the terminal device can directly determine the effect of interference cancellation when there is no downlink signal through the energy of the signal measured by the receiver in the first measurement period. For example, the greater the energy, the less effective the cancellation.

The cancellation effect measured by the terminal device may be used by the receiver to calibrate the algorithm in the self-interference cancellation process.

Further, the terminal device may report information indicating the energy to a network device.

Therefore, the network device may determine, according to the information for indicating the energy reported by the terminal device to the network device, a cancellation effect of the terminal device when performing self-interference cancellation.

For example, the terminal device may report the second value to the network device, or the terminal device may report a comparison result between the second value and the first value to the network device.

Optionally, in other embodiments of the present application, a downlink signal of the terminal device exists in the first measurement period. That is, the terminal device receives the downlink signal sent by the network device while performing the self-interference cancellation process in the first measurement period.

Thereby, the terminal device may perform self-Interference cancellation within the first measurement period, and measure a Signal to Interference plus Noise Ratio (SINR) of the downlink Signal.

For example, the terminal device may determine a first SINR of the downlink signal received when the terminal device does not perform self-interference cancellation in the first measurement period, and determine a second SINR of the downlink signal received when the terminal device performs self-interference cancellation in the first measurement period, where the terminal device may determine a cancellation effect of the self-interference cancellation by comparing the second SINR with the first SINR.

In the embodiment of the present application, an interference signal and a known downlink signal exist in the second measurement period. And since the downlink signal is known, the terminal device may evaluate or calibrate the self-interference cancellation capability of the terminal device in the presence of the downlink signal. For example, since the downlink signal is known, the terminal may measure the SINR of the downlink signal, and then determine whether the effect of interference cancellation is expected.

Further, the terminal device may report the SINR to a network device.

Therefore, the network device may determine, according to the SINR reported by the terminal device, a cancellation effect of the terminal device when performing self-interference cancellation.

For example, the terminal device may report the second SINR to the network device, or the terminal device may report a comparison result of the second SINR and the first SINR to the network device.

Optionally, in some embodiments of the present application, the terminal device may further comprehensively evaluate a total cancellation effect of the terminal device in the self-interference cancellation process according to the cancellation effect in the measurement period when the downlink signal exists and the cancellation effect in the absence of the downlink signal.

For example, in some embodiments of the present application, the method 200 may further comprise:

the terminal equipment acquires a second measurement time interval, wherein the first measurement time interval is different from the second measurement time interval; and the terminal equipment carries out self-interference elimination in the first measurement period and measures the elimination effect of the self-interference elimination.

When the downlink signal of the terminal device does not exist in the first measurement period, the downlink signal of the terminal device exists in the second measurement period. Or when the downlink signal of the terminal device exists in the first measurement period, the downlink signal of the terminal device does not exist in the second measurement period.

It should be understood that, in this embodiment of the present application, an obtaining manner of the second measurement period may be the same as or different from an obtaining manner of the first measurement period, and similarly, an obtaining manner of a parameter for performing self-interference cancellation corresponding to the second measurement period may be the same as or different from an obtaining manner of a parameter for performing self-interference cancellation corresponding to the first measurement period, which is not specifically limited in this embodiment of the present application.

For example, taking the obtaining manner of the second measurement period as an example, the second measurement period may be directly allocated to the terminal device by the network device, or the terminal device may send a request message to the network device to request the network device to allocate the second measurement period corresponding to a specific parameter to the terminal device.

In addition, in this embodiment of the present application, a parameter for performing self-interference cancellation corresponding to the first measurement period and a parameter for performing self-interference cancellation corresponding to the second measurement period may be the same as or different from each other, which is not specifically limited in this embodiment of the present application.

For example, the parameter for the terminal device to perform self-interference cancellation in the first measurement period is the same as the parameter for the terminal device to perform self-interference cancellation in the second measurement period.

Thus, the terminal device may determine the strength and/or quality of the downlink signal of the terminal device without interference according to the cancellation effect of self-interference cancellation in the first measurement period and the cancellation effect of self-interference cancellation in the second measurement period.

Specifically, since the terminal may know the level of interference + background noise that is not cancelled during the first measurement period and a downlink known signal is contained within the second measurement period, if the result of interference cancellation is stable, the terminal apparatus may directly obtain the strength or quality of the downlink signal without interference, taking into account the measurement result during the first measurement period, based on the quality or strength of the downlink signal measured during the second measurement period. For example, the terminal device determines the strength of the downlink signal when the terminal device does not have self-interference, by subtracting the strength of the received signal in the first measurement period from the strength of the downlink signal in the second measurement period.

After the terminal device determines the strength and/or quality of the downlink signal of the terminal device without interference, the current wireless link condition of the terminal device may be evaluated according to the strength and/or quality of the downlink signal of the terminal device without interference.

Further, when the terminal device needs to determine a cancellation effect of the terminal device in a self-interference cancellation process by combining the first measurement period and the second measurement period, the network device may configure the first measurement period and the second measurement period to the terminal device, and explicitly indicate that the first measurement period and the second measurement period correspond to the same parameter for self-interference cancellation.
