Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a self-interference measurement method, device, terminal and network-side equipment. Background Art

[0002] Among the relevant technologies, the full-duplex mode can more flexibly utilize limited spectrum resources to dynamically match business needs, improve resource utilization, and the uplink coverage, latency and other performance of data transmission.

[0003] However, when the terminal operates in full-duplex mode, when receiving the downlink transmission sent by the network-side device, it will receive interference from the signal of the terminal's own uplink transmission, which is terminal self-interference. Therefore, it is necessary to perform certain interference suppression or interference isolation at both ends of the terminal, such as adjusting the terminal's transmit power. The specific interference suppression level depends on the terminal's devices and implementation.

[0004] At present, the network side equipment cannot obtain the relevant information of the terminal self-interference. For example, the terminal adjusts the transmission power to suppress self-interference, and the terminal transmits based on the adjusted transmission power, but the network side equipment is unaware of this behavior of the terminal. As a result, the network side equipment does not know the actual transmission parameters of the terminal, and the network side equipment cannot adjust the relevant parameters based on the actual transmission parameters of the terminal, thereby affecting the transmission performance of the network side equipment.

It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0043] For better understanding, the relevant concepts and principles involved in the embodiments of the present application are explained below.

[0044] When deploying traditional cellular networks, based on the available spectrum and service characteristics, frequency division duplex (FDD) or time division duplex (TDD) can be used. When FDD is used, uplink and downlink transmissions are located at different frequencies, and the two do not interfere with each other and can be carried out simultaneously. When TDD is used, uplink and downlink transmissions are located at the same frequency and are carried out in a staggered manner using time division. Both duplex methods have their own advantages and disadvantages.

[0045] In order to more flexibly utilize limited spectrum resources, dynamically match business needs, improve resource utilization efficiency, and the uplink coverage, latency and other performance of data transmission, a flexible duplex mode is proposed. A flexible duplex mode is: full duplex on the network side (also called non-overlapping sub-band full duplex, SBFD), that is, at the same time, uplink transmission and downlink transmission can be carried out simultaneously at different frequency domain positions. To avoid interference between uplink and downlink, a certain guard band (Guard Band, GB) can be reserved between the frequency domain positions corresponding to different transmission directions (corresponding to the duplex sub-band); half duplex on the terminal side, that is, consistent with TDD, at the same time, only uplink transmission or downlink transmission can be carried out, and both cannot be carried out at the same time. It can be understood that in this duplex mode, the uplink transmission and downlink transmission on the network side at the same time can only be for different terminals.

[0046] Figure 1b A schematic diagram of the flexible duplex mode is given. In a part of the downlink symbols, the network side semi-statically divides the frequency domain of a single carrier into three duplex subbands, where the two sides of the carrier are downlink duplex subbands and the center is uplink duplex subbands, to reduce interference to adjacent carriers. In the third time slot, UE1 and UE2 perform uplink transmission and downlink reception respectively. At this time, the terminal works in half-duplex mode.

[0047] When the terminal works in full-duplex mode, when receiving the downlink transmission sent by the base station, it will be interfered by the signal from the terminal's own uplink transmission. Therefore, it is necessary to perform certain interference suppression or interference isolation at both ends of the UE, and the specific interference suppression level depends on the UE's devices and implementation. At the same time, the impact of self-interference is also related to the UE's ongoing downlink (DL) or uplink (UL) transmission. Since the terminal works in full-duplex mode, the uplink transmission sent by the terminal generates self-interference, and the network side cannot obtain the relevant information of the terminal's self-interference, which affects the transmission performance of the network side. In response to this problem, an embodiment of the present application proposes a self-interference measurement method and related equipment.

[0048] In conjunction with the accompanying drawings, the following describes in detail some embodiments and their application scenarios of the self-interference measurement method, device, terminal, network side equipment and other related equipment provided in the embodiments of the present application.

[0049] Please refer to Figure 2 , Figure 2 1 is a flow chart of a self-interference measurement method provided in an embodiment of the present application, and the method is executed by a terminal. Figure 2 As shown, the method comprises the following steps:

[0050] Step 201: A terminal receives configuration information sent by a network-side device, where the configuration information is information related to self-interference (SI) measurement of the terminal.

[0051] In an embodiment of the present application, a network side device sends configuration information to a terminal, and the configuration information is information related to SI measurement of the terminal. For example, the configuration information may include a reporting configuration for instructing the terminal to report SI measurement results, or may also include relevant information of SI measurement resources used for SI measurement, such as relevant information of frequency domain resources used for SI measurement, relevant information of time domain resources, etc., which will be specifically explained in subsequent embodiments and will not be listed in detail here.

[0052] It should be noted that in some implementations, self-interference measurement may also be referred to as interference measurement, or interference channel quality measurement, interference signal strength measurement, full-duplex channel measurement, etc., and the embodiments of the present application do not specifically limit this. In addition, in some implementations, SI measurement resources may also be referred to as interference measurement resources, or interference channel quality measurement resources, interference signal strength measurement resources, full-duplex interference measurement resources, etc., and the embodiments of the present application do not specifically limit this.

[0053] Step 202: The terminal performs SI measurement according to the configuration information to obtain an SI measurement result.

[0054] It can be understood that after receiving the configuration information related to the SI measurement of the terminal configured by the network side device, the terminal performs SI measurement according to the configuration information to obtain the SI measurement result.

[0055] For example, the configuration information includes a reporting configuration, and the reporting configuration is used to instruct the terminal to report a received signal strength indication (RSSI), and the SI measurement of the terminal includes RSSI measurement. Wherein, the reporting configuration includes SI measurement resources, for example, the frequency domain position and time domain position of the SI measurement resources, and the terminal performs SI measurement at the frequency domain position and time domain position corresponding to the SI measurement resources, and measures the RSSI of the frequency domain bandwidth corresponding to the downlink SI measurement resources to obtain the RSSI result, that is, the SI measurement result.

[0056] It should be noted that the specific content of the configuration information may also be other possible situations, and the terminal may also perform SI measurement according to the configuration information in other possible situations, which are not specifically listed here.

[0057] Step 203: The terminal reports the SI measurement result to the network side device.

[0058] It can be understood that after the terminal performs SI measurement according to the configuration information and obtains the SI measurement result, the terminal reports the SI measurement result to the network side device. In this way, the network side device can obtain the relevant information of the terminal side self-interference, thereby helping the network side device to adjust the transmission with the terminal according to the relevant information of the terminal side self-interference, so as to improve the transmission performance between the network side device and the terminal.

[0059] Optionally, in an embodiment of the present application, when the terminal is operating in full-duplex mode, SI measurement is performed according to the configuration information configured by the network side device, SI measurement results are obtained, and the SI measurement results are reported. It can be understood that when the terminal is operating in full-duplex mode, when the terminal receives the downlink transmission sent by the network side device, it will be interfered by the signal from the terminal's own uplink transmission. The terminal performs SI measurement according to the configuration information to obtain the SI measurement result. The SI measurement result can characterize the relevant information of the terminal being interfered by its own uplink transmission signal, such as the interference intensity. The terminal reports the SI measurement result, so that the network side device can also obtain the relevant information of the terminal side self-interference, and the network side device can also adjust the transmission with the terminal according to the relevant information of the terminal side self-interference, and schedule and allocate appropriate resources for the terminal. For example, if the network side device feels that the downlink transmission is more important, the network side device can instruct the terminal to reduce the transmission power; or the network side device can also ensure the frequency domain interval between the uplink and downlink transmissions through scheduling to avoid conflicts between the uplink and downlink transmissions, etc., so as to improve the transmission performance between the network side device and the terminal.

[0060] Optionally, the configuration information includes at least one of the following:

[0061] Reporting configuration, the reporting configuration is used to instruct the terminal to report the SI measurement result, such as the reporting type of the SI measurement result, the type and identifier of the SI measurement resource, etc.;

[0062] Related information of SI measurement resources, where the SI measurement resources are used for SI measurement, such as frequency domain resources, time domain resources, etc. used for SI measurement.

[0063] Optionally, the configuration information sent by the network side device may include multiple reporting configurations. In this case, the terminal performs SI measurement resources on the SI measurement resources associated with each reporting configuration according to the configuration information, and obtains the SI measurement results corresponding to each reporting configuration, that is, multiple SI measurement results, and the terminal reports the multiple SI measurement results.

[0064] For example, reporting configuration 1 is associated with SI measurement resource 1, the transmission power of SI measurement resource 1 is P1, and the SI measurement result corresponding to reporting configuration 1 is Result 1; reporting configuration 2 is associated with SI measurement resource 2, the transmission power of SI measurement resource 2 is P2, and the SI measurement result corresponding to reporting configuration 2 is Result 2. The terminal can report Result 1 and Result 2 separately, or can report them together.

[0065] Alternatively, the configuration information sent by the network side device includes only one reporting configuration, which contains multiple sub-reporting configurations. These sub-reporting configurations share the same reporting parameters and reporting behaviors. The content included in each sub-reporting configuration can be configured independently, that is, each sub-reporting configuration can be an independent configuration of the type of SI measurement resource, the identifier of the SI measurement resource, and other contents.

[0066] Optionally, the configuration information sent by the network side device may include multiple SI measurement resources. In this case, the terminal performs SI measurement on each SI measurement resource and the configuration parameters corresponding to each SI measurement resource according to the configuration information, and obtains the SI measurement results corresponding to each SI measurement resource, that is, multiple SI measurement results, and the terminal reports the multiple SI measurement results.

[0067] For example, the transmit power of SI measurement resource 1 is P1, and the corresponding SI measurement result is Result 1; the transmit power of SI measurement resource 2 is P2, and the corresponding SI measurement result is Result 2. The terminal can report Result 1 and Result 2 separately, or can report them together.

[0068] Optionally, the reporting configuration includes at least one of the following:

[0069] Reporting type of SI measurement results, such as RSSI, layer 1 signal-to-noise and interference ratio (L1-SINR), etc.

[0070] The type of SI measurement resources, such as the type of uplink signal or channel, such as Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), etc.

[0071] Identifier (ID) of SI measurement resource;

[0072] The sending resource location of SI measurement;

[0073] The receiving resource location of SI measurement;

[0074] The transmit power of the SI measurement resource;

[0075] The frequency location of the SI measurement resource;

[0076] The frequency domain bandwidth of the SI measurement resource;

[0077] SI measures the spatial characteristics of resources, including Transmission Configuration Indicator (TCI), Quasi co-location (QCL), spatial relation information (spatial relationinfo), etc.

[0078] Modulation order (MOD) of SI measurement resources;

[0079] The frequency domain spacing between the downlink SI measurement resource and the uplink subband (UL subband);

[0080] The frequency domain interval between the uplink SI measurement resource and the downlink subband (DL subband).

[0081] Optionally, the relevant information of the SI measurement resource includes at least one of the following:

[0082] The type of uplink transmission, including the type of uplink signal or channel, such as Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), etc.

[0083] Frequency domain resource information, including, for example, a starting frequency domain position, an ending frequency domain position, a frequency domain offset value, a frequency domain resource quantity or range, a bandwidth part (Bandwidth Part, BWP), etc. The frequency domain resources may include uplink frequency domain resources and downlink frequency domain resources;

[0084] Uplink transmit power parameters, including target receive power, power offset value, preset transmit power, etc.;

[0085] Spatial characteristics, including TCI, QCL, spatial relation information, etc.;

[0086] Time domain resource information, including the starting time domain position, the ending time domain position, the time domain offset value, the number or range of time domain resources, the symbol number, the time slot number, etc.

[0087] Uplink modulation and coding scheme (MCS) may be configured with one or more MCSs.

[0088] Among them, the SI measurement resources can be divided into downlink SI measurement resources (also referred to as first resources, first SI measurement resources, etc.) and uplink SI measurement resources (also referred to as second resources, second SI measurement resources, etc.); or, downlink and uplink may not be distinguished and are collectively referred to as SI measurement resources.

[0089] It should be noted that when the relevant information of the SI measurement resource includes the type of uplink transmission, it means that the resource measured by the terminal SI is a certain type of uplink signal or uplink channel, for example, the resource measured by the SI is PUSCH or SRS, etc. If the network side device does not configure the type of uplink transmission, for example, the relevant information of the SI measurement resource does not include the type of uplink transmission, the type of measurement signal or channel is not limited.

[0090] For example, the network side device schedules or triggers a certain uplink channel or signal when the terminal performs SI measurement. When performing SI measurement, the terminal can perform SI measurement according to the uplink channel or signal scheduled or triggered by the network side device.

[0091] Optionally, when the relevant information of the SI measurement resource includes the type of the uplink transmission, and the type of the uplink transmission includes an uplink signal or a channel type, the terminal performs SI measurement according to the configuration information, including:

[0092] The terminal performs SI measurement according to the uplink signal or channel type.

[0093] For example, the type of the uplink transmission is PUSCH or PUCCH, and the terminal performs SI measurement according to the uplink signal or channel type, including at least one of the following:

[0094] The terminal performs SI measurement according to the dynamically scheduled PUSCH or PUCCH;

[0095] The terminal performs SI measurement according to the semi-statically configured PUSCH or PUCCH.

[0096] Alternatively, the type of the uplink transmission is SRS or DMRS, and the terminal performs SI measurement according to the uplink signal or channel type, including:

[0097] The terminal performs SI measurement according to the SRS or DMRS.

[0098] Alternatively, when the configuration information configured by the network side device does not include the uplink transmission type of the SI measurement resource, the terminal performs SI measurement according to the uplink channel or uplink signal scheduled by the network side device. For example, the network side device only configures the locations at which the terminal performs measurement, and the terminal performs SI measurement according to the configuration information, including at least one of the following:

[0099] The terminal performs SI measurement according to the dynamically scheduled PUSCH or PUCCH;

[0100] The terminal performs SI measurement according to the semi-statically configured PUSCH or PUCCH.

[0101] Exemplarily, the terminal sends PUSCH or PUCCH according to the scheduling of the network side device and performs SI measurement at the same time.

[0102] Optionally, if there is no dynamically scheduled PUSCH or PUCCH at the current moment, or no semi-statically configured PUSCH or PUCCH, the terminal does not perform SI measurement at the current moment, that is, the terminal skips SI measurement at the current moment.

[0103] In an embodiment of the present application, when the relevant information of the SI measurement resource includes the frequency domain resource information, the frequency domain resource information includes at least one of the frequency domain position of the downlink SI measurement resource and the frequency domain position of the uplink SI measurement resource.

[0104] For example, the network side device may be configured with the frequency domain position of the downlink SI measurement resource and the frequency domain position of the uplink SI measurement resource respectively. The downlink SI measurement resource may include the frequency domain resource in the downlink subband or the frequency domain resource in the guard band; the uplink SI measurement resource may include the frequency domain resource in the uplink subband or the frequency domain resource in the guard band.

[0105] Alternatively, the network side device may configure the frequency domain position of the downlink SI measurement resource, and configure the frequency domain interval between the downlink SI measurement resource and the uplink SI measurement resource. Wherein, at the SI measurement moment, the uplink channel or signal sent by the terminal must satisfy: greater than or equal to the frequency domain interval with the downlink SI measurement resource, or, the uplink channel or signal sent by the terminal must satisfy: less than or equal to the frequency domain interval with the downlink SI measurement resource.

[0106] Alternatively, the network side device may be configured with the frequency domain position of the uplink SI measurement resource, and the frequency domain interval between the uplink SI measurement resource and the downlink SI measurement resource. Wherein, at the SI measurement moment, when the terminal measures SI in the downlink, the corresponding frequency domain resource needs to satisfy: greater than or equal to the frequency domain interval with the uplink SI measurement resource, or, the corresponding frequency domain resource needs to satisfy: less than or equal to the frequency domain interval with the uplink SI measurement resource.

[0107] Optionally, the network side device may also only configure the frequency domain position of the downlink SI measurement resources. In this case, when the terminal performs SI measurement, the terminal performs SI measurement based on the actual uplink transmission in the uplink subband, that is, the frequency domain position of the uplink transmission can occupy any or all of the frequency domain resources of the uplink subband.

[0108] Optionally, the network side device may also only configure the frequency domain position of the uplink SI measurement resource. In this case, when the terminal performs SI measurement, the terminal performs measurement on the entire downlink subband or protection band.

[0109] In the embodiment of the present application, when the relevant information of the SI measurement resource includes the uplink transmit power parameter, the uplink transmit power parameter includes at least one of the following:

[0110] The current transmit power, i.e., the actual transmit power of the uplink signal or signal corresponding to the SI measurement resource, where the actual transmit power is the transmit power after uplink power control adjustment (open-loop or closed-loop power control);

[0111] Target receive power, that is, the target receive power of the uplink transmission reaching the network side device after the terminal performs uplink power control adjustment; for users in the cell center, the target receive power is lower, and for users at the cell edge, the target receive power is higher. Different target receive powers will affect the terminal self-interference;

[0112] A power offset value, for example, a power offset value relative to the current transmit power, in dB, such as -3 dB;

[0113] Preset transmit power, such as 0dB, 10dB, 20dB, etc.

[0114] Optionally, when the relevant information of the SI measurement resource includes the spatial characteristic, the spatial characteristic includes at least one of a spatial characteristic of a downlink SI measurement resource and a spatial characteristic of an uplink SI measurement resource.

[0115] For example, the network side device configures the spatial characteristics of the downlink SI measurement resources and the spatial characteristics of the uplink SI measurement resources respectively.

[0116] Alternatively, the network side device only configures the spatial characteristics of the downlink SI measurement resources. In this case, the spatial characteristics of the uplink SI measurement resources are determined according to the spatial characteristics of the downlink SI measurement resources.

[0117] Alternatively, the network side device only configures the spatial characteristics of the uplink SI measurement resources. In this case, the spatial characteristics of the downlink SI measurement resources are determined according to the spatial characteristics of the uplink SI measurement resources.

[0118] Optionally, when the relevant information of the SI measurement resource includes the time domain resource information, the time domain resource information includes at least one of the time domain position of the downlink SI measurement resource and the time domain position of the uplink SI measurement resource.

[0119] For example, the network side device configures the time domain position of the downlink SI measurement resource and the time domain position of the uplink SI measurement resource respectively.

[0120] Alternatively, the network side device only configures the time domain position of the downlink SI measurement resource. In this case, it can be assumed that the time domain position of the uplink SI measurement resource is aligned with the time domain position of the downlink SI measurement resource.

[0121] Alternatively, the network side device only configures the time domain position of the uplink SI measurement resource. In this case, it can be assumed that the time domain position of the downlink SI measurement resource is aligned with the time domain position of the uplink SI measurement resource.

[0122] In the embodiment of the present application, the terminal performs SI measurement according to the configuration information configured by the network side device, wherein the SI measurement performed by the terminal may include at least one of the following:

[0123] The terminal measures all frequency domain resources of the downlink subband, or measures the RSSI on the frequency domain bandwidth or guard band corresponding to the downlink SI measurement resource;

[0124] The terminal measures the received power on the resource elements (ResourceElement, RE) corresponding to the downlink SI measurement resources and the uplink SI measurement resources.

[0125] Exemplarily, the terminal may measure all frequency domain resources of the downlink sub-band at the time domain position corresponding to the SI measurement resource, or measure the RSSI on the frequency domain bandwidth or guard band corresponding to the downlink SI measurement resource. It should be noted that the network side device does not perform downlink transmission to the terminal on all frequency domain resources of the downlink sub-band or the frequency domain bandwidth corresponding to the downlink SI measurement resource to avoid affecting the SI measurement of the terminal.

[0126] Alternatively, the terminal may measure the received power on the REs corresponding to the downlink SI measurement resources and the uplink SI measurement resources at the time domain position corresponding to the SI measurement resources, for example, measuring the average received power on the REs corresponding to the downlink SI measurement resources and the uplink SI measurement resources. The uplink signal corresponding to the uplink SI measurement resource is SRS or DMRS. Optionally, the network side device does not perform downlink transmission to the terminal on the REs corresponding to the downlink SI measurement resources, or performs rate matching on the downlink transmission to avoid affecting the SI measurement of the terminal.

[0127] Optionally, in the embodiment of the present application, after the terminal receives the configuration information configured by the network side device, the method further includes:

[0128] The terminal sends an SI measurement signal to the network side device according to the configuration information.

[0129] Exemplarily, after receiving the configuration information configured by the network side device, at a specific moment, which may be determined according to the configuration information or according to other instructions of the network side device, the terminal sends an SI measurement signal to the network side device according to the configuration information, and performs SI measurement according to the configuration information to obtain an SI measurement result. It can be understood that the terminal sends the SI measurement signal according to the configuration information, so that the network side device can know that the terminal is performing SI measurement, and also makes the terminal send the SI measurement signal after receiving the configuration information of the network side device, so that this sending behavior is controllable, avoiding unnecessary sending behavior of the terminal. Among them, the SI measurement signal can be PUSCH, PUCCH, SRS, Physical Random Access Channel (PRACH)

[0130] Optionally, the terminal sending an SI measurement signal to the network side device according to the configuration information includes:

[0131] The terminal sends a corresponding uplink signal or channel on a frequency domain bandwidth corresponding to the uplink sub-band SI measurement resource according to the configuration information.

[0132] For example, the terminal sends a corresponding uplink signal or channel on the frequency domain bandwidth corresponding to the uplink subband SI measurement resource at the time domain position corresponding to the SI measurement resource according to the configuration information, and the uplink signal or channel may be a dynamically scheduled or semi-statically configured uplink signal or channel, such as PUSCH, PUCCH, SRS, etc. Among them, the uplink signal or channel sent by the terminal is also used to implicitly indicate the SI measurement signal.

[0133] Optionally, the method further comprises:

[0134] When the content reported by the terminal includes a layer 1 signal-to-noise and interference ratio (L1-SINR), the terminal (in a downlink subband) performs channel measurement on a channel state information reference signal (CSI-RS) from a network side device and performs interference measurement on a CSI interference measurement (CSI Interference Measurement, CSI-IM) signal to obtain channel information and neighboring cell interference information, respectively;

[0135] The terminal obtains the L1-SINR according to the channel information, the neighboring cell interference information and the SI measurement result (eg RSSI).

[0136] Further, the terminal reports the L1-SINR.

[0137] In the embodiment of the present application, the SI measurement performed by the terminal may be performed by triggering a network side device. Optionally, the terminal performs SI measurement according to the configuration information, including:

[0138] The terminal receives a trigger signal sent by the network side device;

[0139] The terminal performs SI measurement based on the trigger signal and according to the configuration information.

[0140] In an embodiment of the present application, the SI measurement behavior on the terminal side may be triggered by a network side device, for example, the network side device may send a corresponding trigger signal, and the terminal performs SI measurement based on the configuration information when receiving the trigger signal. It should be noted that the network side device may send the trigger signal irregularly, and the terminal performs SI measurement based on the configuration information when receiving the trigger signal, thereby making the SI measurement behavior on the terminal side controllable.

[0141] Optionally, the trigger signal is a periodic trigger signal. For example, the network side device may be configured with a periodic measurement window, in which the terminal performs SI measurement according to the reporting configuration configured by the network side device or the relevant information of the SI measurement resource, and reports the SI measurement result. In this way, by configuring the periodic measurement window, it is possible to avoid the network side device from frequently sending the trigger signal, thereby saving the power consumption of the network side device.

[0142] Optionally, each SI measurement result reported by the terminal includes at least one of the following:

[0143] Reporting type of SI measurement results, such as RSSI, L1-SINR, etc.

[0152] Modulation method of SI measurement resources;

[0153] Frequency domain spacing between downlink SI measurement resources and uplink subbands;

[0154] The frequency domain interval between the uplink SI measurement resource and the downlink subband.

[0155] For example, the terminal may report all or part of the content in Table 1 below:

[0156] Table 1

[0157]

[0158] It should be noted that the above Table 1 is only an example of the SI measurement result reported by the terminal, and does not constitute a limitation on the SI measurement result of the present application.
