[0042] FIG1 is a block diagram of a wireless communication system applicable to an embodiment of the present application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device (Wearable Device), an aircraft (Flight Vehicle), a vehicle-mounted device (VUE), a ship-mounted device, a pedestrian user equipment (PUE), a smart home (home appliances with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), a game console, a personal computer (PC), an ATM, or a self-service machine, or other terminal-side devices. Wearable devices include: smart watches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle-mounted device can also be called a vehicle-mounted terminal, vehicle-mounted controller, vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip or vehicle-mounted unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.
[0043] The network-side device 12 may include an access network device or a core network device, wherein the access network device may also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node. Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home evolved Node B (home evolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the relevant field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary.

[0044] The core network equipment may include but is not limited to at least one of the following: core network node, core network function, mobility management entity (MME), access mobility management function (AMF), session management function (SMF), user plane function (UPF), policy control function (PCF), policy and charging rules function unit (PCRF), edge application service discovery function (EASDF), unified data management (UDM), unified data repository (UDR), home user server (HSS), centralized network configuration (CNC), network storage function (NRF), network exposure function (NEF), local NEF (L-NEF), binding support function (BSF), application function ( It should be noted that in the embodiments of the present application, only the core network device in the NR system is introduced as an example, and the specific type of the core network device is not limited.
[0045] In some communication scenarios, in order to more flexibly utilize limited spectrum resources to dynamically match business needs, improve resource utilization efficiency, and improve uplink coverage, latency and other performance of data transmission, a flexible duplex mode sub-band full duplex (SBFD) is proposed, such as non-overlapping SBFD. Specifically, full duplex on the network side means that at the same time, uplink transmission and downlink transmission of network-side equipment can be carried out simultaneously at different frequency domain positions. To avoid interference between uplink and downlink, a certain guard band can be reserved between the frequency domain positions (corresponding to duplex sub-bands) corresponding to different transmission directions; at the same time, half duplex is adopted on the terminal side, which is different from time division duplex (TDD). In accordance with TDD (Time Division Duplexing), only uplink or downlink transmissions can be performed at the same time, not both. Specifically, Figure 2 illustrates this flexible duplexing scheme. Within a portion of downlink symbols, the network semi-statically divides the frequency domain of a single carrier into three duplex subbands: downlink duplex subbands on either side of the carrier and uplink duplex subbands in the center, minimizing interference with adjacent carriers. In the third time slot, UE1 and UE2 perform uplink transmission and downlink reception, respectively.
[0046] In some communication scenarios, terminals operate in full-duplex mode. This means that at the same time, uplink and downlink transmissions can occur simultaneously at different frequency locations for a terminal device. As shown in Figure 3, in some symbols, network-side devices can perform both uplink and downlink transmissions simultaneously (network-side full-duplex), and in some symbols, terminals can perform both uplink and downlink transmissions simultaneously (terminal-side full-duplex).
[0047] It should be noted that the above Figures 2 and 3 are only examples of duplexing on the terminal and network sides. The embodiments of the present application are applied to the full-duplex scenario on the terminal side and are not limited to the scenario shown in Figure 3. Specifically, the embodiments of the present application are not limited to the full-duplex scenario.
[0048] In the following, in conjunction with the accompanying drawings, an interference measurement method, a measurement result receiving method, an apparatus and a device provided by the embodiments of the present application are described in detail through some embodiments and their application scenarios.
[0049] Please refer to FIG4 , which is a flowchart of an interference measurement method provided in an embodiment of the present application. As shown in FIG4 , the method includes the following steps:
[0050] Step 401: The terminal obtains a transmission power control parameter of a first uplink transmission, where the first uplink transmission is used for self-interference measurement.
[0051] The first uplink transmission may include at least one of the following:
[0052] Uplink signal, uplink data, uplink channel.
[0053] For example: Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS), etc.
[0054] In some implementations, the first uplink transmission may be used only for self-interference measurement, or, in addition to being used for self-interference measurement, the first uplink transmission may also be used to transmit information, such as data or signals, to the network side.
[0055] The transmission power control parameter may be a relevant parameter for determining the transmission power of the first uplink transmission, such as including at least one of the following:
[0056] Target received power, path loss compensation factor, and power offset.
[0057] The above-mentioned acquisition of the transmission power control parameter of the first uplink transmission may be that the terminal receives the transmission power control parameter of the first uplink transmission configured by the network side device, or the terminal acquires the transmission power control parameter of the first uplink transmission based on a predefined rule.
[0058] Step 402: The terminal sends the first uplink transmission based on the transmission power control parameter.
[0059] The sending of the first uplink transmission based on the transmission power control parameter may be sending the first uplink transmission based on a transmission power corresponding to the transmission power control parameter.
[0060] Step 403: The terminal performs self-interference measurement and reports the measurement result of the self-interference measurement to the network side device.
[0061] In the embodiment of the present application, self-interference measurement may also be directly referred to as interference measurement, or interference channel quality measurement, or interference signal strength measurement, full-duplex channel measurement, etc.
[0062] The terminal performing the self-interference measurement refers to performing the self-interference measurement on the first uplink transmission sent by the terminal, such as measuring the self-interference strength. The self-interference strength can be represented by different measurement standards, such as at least one of the following:
[0063] Received Signal Strength Indication (RSSI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Layer 1 Signal to Interference plus Noise Ratio (L1-SINR), etc.
[0064] In the embodiment of the present application, the above steps enable the terminal to perform self-interference measurement and report the measurement results of the self-interference measurement to the network-side device, thereby improving the measurement performance of the terminal. In addition, reporting the measurement results of the self-interference measurement to the network-side device can also avoid the problem of affecting the communication performance between the terminal and the network-side device due to the network-side device being unable to know the terminal's interference performance, thereby facilitating improved communication performance between the terminal and the network-side device.
[0065] In some embodiments, after reporting the measurement results of the self-interference measurement to the network side device, the network side device can perform corresponding scheduling on the terminal based on the measurement results, for example, the network side device adjusts the frequency domain interval between the downlink transmission and uplink transmission of the terminal, or the network side device adjusts the transmission power of the downlink transmission or adjusts the receiving power of the uplink transmission, etc., so that the terminal and the network side device can effectively communicate in the case of self-interference.
[0066] As an optional implementation manner, the terminal obtains a transmission power control parameter of the first uplink transmission, including:
[0067] The terminal obtains a transmission power control parameter configured by the network side for the first uplink transmission; or
[0068] The terminal determines a transmission power control parameter of the first uplink transmission based on a predefined rule; or
[0069] The terminal obtains a default or predefined transmission power control parameter of the first uplink transmission.
[0070] The terminal obtaining the transmission power control parameter configured by the network side for the first uplink transmission may be that the terminal receives configuration signaling sent by a network side device, and the configuration signaling includes the transmission power control parameter configured by the network side for the first uplink transmission.
[0071] The above-mentioned predefined rules may be defined by the protocol or pre-configured by the network side, or predetermined by the terminal.
[0072] The above-mentioned default or predefined transmission power control parameter of the first uplink transmission may be a transmission power control parameter defined by a protocol or pre-configured by the network side, or a transmission power control parameter predetermined by the terminal.
[0073] In this implementation, the transmission power control parameter of the first uplink transmission can be obtained in multiple ways to meet the requirements of different terminals or different scenarios, thereby improving the flexibility of the terminal in reporting the self-interference measurement result.
[0074] Optionally, the predefined rule includes at least one of the following:
[0075] In a case where the first uplink transmission is a non-periodic uplink transmission, the transmission power control parameter of the first uplink transmission includes a transmission power control parameter indicated by the network side;
[0076] In a case where the first uplink transmission is an uplink transmission scheduled by the network side, the transmission power control parameter of the first uplink transmission includes a transmission power control parameter indicated by the network side;
[0077] In the case where the first uplink transmission is periodic, the transmission power control parameter of the first uplink transmission includes: a transmission power control parameter configured by the network side, or a transmission power control parameter applicable only to self-interference measurement;
[0078] In a case where the first uplink transmission is semi-statically configured, the transmission power control parameter of the first uplink transmission includes: a transmission power control parameter configured on the network side, or a transmission power control parameter applicable only to self-interference measurement;
[0079] In the case where the first uplink transmission is used only for self-interference measurement, the transmission power control parameter of the first uplink transmission includes: a transmission power control parameter applicable only to self-interference measurement;
[0080] In a case where the first uplink transmission is used for self-interference measurement and uplink content transmission, the transmission power control parameter of the first uplink transmission includes a universal transmission power control parameter, and the universal transmission power control parameter is applicable to multiple uplink transmissions;
[0081] The transmission power control parameter of the first uplink transmission is a transmission power control parameter indicated by downlink indication signaling received by the terminal.
[0082] The transmission power control parameter indicated by the network side may be a transmission power control parameter dynamically indicated by the network side, and the transmission power control parameter configured by the network side may be a transmission power control parameter statically or semi-statically configured by the network side.
[0083] The transmission power control parameters indicated by the network side can realize dynamic acquisition of the transmission power control parameters of the first uplink transmission, which is conducive to improving the measurement performance of the self-interference measurement. The transmission power control parameters configured by the network side can save signaling transmission overhead.
[0084] The above-mentioned transmission power control parameters that are only applicable to self-interference measurement can be understood as follows: the transmission power control parameters are independent of the transmission power control parameters of other uplink transmissions. Other uplink transmissions are uplink transmissions that are not used for self-interference measurement, such as normal PUCCH, PUSCH, SRS or physical random access channel (PRACH). It can be understood that normal PUCCH, PUSCH, SRS, PRACH are mainly used to transmit uplink control information, service data / information, channel measurement, random access, etc. At this time, these transmissions will be received by other communication devices except the terminal that sends the PUCCH, PUSCH, SRS, and PRACH.
[0085] In some implementations, the transmission power control parameter applicable only to self-interference measurement may be configured by the network side for the first uplink transmission, or the transmission power control parameter applicable only to self-interference measurement may be agreed upon by a protocol.
[0086] By using the transmission power control parameters that are only applicable to self-interference measurement, it is possible to implement the use of dedicated transmission power control parameters for self-interference measurement, which is beneficial to improving the measurement performance of the self-interference measurement.
[0087] The above-mentioned first uplink transmission is used for self-interference measurement and uplink content, which can be understood as the above-mentioned first uplink transmission is not only used for self-interference measurement, but also used for normal uplink transmission.
[0088] The above-mentioned universal transmission power control parameter can be understood as a transmission power control parameter that is not a transmission power control parameter specifically configured for self-interference measurement, and the transmission power control parameter can be applied to all or part of the terminal's uplink transmission, for example, the transmission power control parameter applicable to PUCCH, PUSCH, SRS or PRACH.
[0089] The above-mentioned universal transmission power control parameters can reduce the configuration overhead of the transmission power control parameters, that is, there is no need to additionally configure transmission power control parameters dedicated to self-interference measurement.
[0090] The downlink indication signaling may be downlink control information (DCI), medium access control control element (MAC CE), or radio resource control (RRC) signaling.
[0091] The transmission power control parameter indicated by the downlink indication signaling can flexibly indicate the transmission power control parameter of the first uplink transmission, so that the self-interference measurement can more easily meet the measurement requirements between the terminal and the network side device.
[0092] Optionally, the transmission power control parameter configured by the network side for the first uplink transmission, acquired by the terminal, includes at least one of the following:
[0093] Transmit power control parameters applicable only to self-interference measurements;
[0094] a power offset of the first uplink transmission;
[0095] a transmission power control parameter of the first uplink transmission configured with resource granularity;
[0096] a transmission power control parameter of the first uplink transmission corresponding to at least one resource interval;
[0097] A transmission power control parameter of the first uplink transmission corresponding to at least one transmission configuration parameter.
[0098] The transmission power control parameters applicable only to self-interference measurement are described in the above embodiments and will not be elaborated here.
[0099] The transmission power control parameter of the first uplink transmission configured with resource as granularity may be a transmission power control parameter of the first uplink transmission configured for one or more resources.
[0100] Optionally, the resources include:
[0101] Self-interference measurement resources.
[0102] The self-interference measurement resource may be referred to as a full-duplex interference measurement resource, or an interference channel quality measurement resource, or an interference signal strength measurement resource, or a full-duplex interference measurement resource, etc.
[0103] The self-interference measurement resource may be a resource for sending the first uplink transmission, or a resource for performing self-interference measurement, such as a self-inference reference signal (SI-RS).
[0104] In this way, it is possible to configure the transmission power control parameters of uplink transmission for one or more self-interference measurement resources, thereby improving the accuracy of self-interference measurement.
[0105] In some implementations, the above resources may be resources for different uplink transmissions, such as PUCCH resources, PUSCH resources, SRS resources, and the like.
[0106] The at least one resource interval may be at least one frequency domain resource interval, such as a frequency domain interval between a subband for downlink (DL) transmission and a subband for uplink transmission, where a subband refers to one or more continuous or discontinuous physical resource blocks (PRBs) in the frequency domain. In some embodiments, it may also be at least one time domain resource interval. In some embodiments, each resource interval in the at least one resource interval may represent a resource interval type, i.e., the transmission power control parameter of the corresponding first uplink transmission is configured according to the resource interval type.
[0107] The above transmission configuration parameters may be configuration parameters for the first uplink transmission, or may be hardware configuration parameters of the terminal used for the first uplink transmission.
[0108] In the embodiment of the present application, the above-mentioned transmission configuration parameters may also be referred to as transmission configuration.
[0109] In some implementations, the transmission configuration parameters include at least one of the following:
[0110] Beam, antenna panel (pannel), TRP, spatial information (spatial information), Quasi co-location (QCL), Control resource set (CORESET) pool index.
[0111] Among them, the above TRP is the TRP of the above terminal.
[0112] For example, configuring the corresponding transmission power control parameters of the first uplink transmission for at least one beam, configuring the corresponding transmission power control parameters of the first uplink transmission for at least one antenna panel, configuring the corresponding transmission power control parameters of the first uplink transmission for at least one TRP, configuring the corresponding transmission power control parameters of the first uplink transmission for at least one spatial information, configuring the corresponding transmission power control parameters of the first uplink transmission for at least one QCL, and configuring the corresponding transmission power control parameters of the first uplink transmission for at least one CORESET pool index (CORESET pool index).
[0113] The power offset of the first uplink transmission may be a power offset used to determine the transmission power of the first uplink transmission. In some embodiments, the transmission power of the first uplink transmission may be a non-continuous value, for example, it can only take specific values, such as 13dBm, 20dBm, and 26dBm. In this way, when determining the uplink transmission power based on the power offset or transmission power parameter, the terminal may also quantize to the nearest self-interference power. That is, when the transmission power determined based on the power offset / transmission power control parameter is not equal to one of the specific values, such as 13dBm, 20dBm, and 26dBm, it needs to be quantized to a value among 13dBm, 20dBm, and 26dBm, such as the closest specific transmission power value, or it may be quantized downward or upward to the closest specific transmission power value.
[0114] In the above implementation, it is possible to support configuring the transmission power control parameters of the first uplink transmission in multiple dimensions, thereby making the self-interference measurement more accurate.
[0115] Optionally, the power offset of the first uplink transmission includes at least one of the following:
[0116] a first power offset and a second power offset;
[0117] The first power offset is an offset relative to a transmission power control parameter of the second uplink transmission, or the first power offset is an offset relative to energy per resource element (EPRE) of the second uplink transmission;
[0118] The second power offset is an offset equivalent to the downlink received power of the first downlink transmission, or the second power offset is an offset equivalent to the EPRE of the first downlink transmission.
[0119] The second uplink transmission may be an uplink transmission agreed upon by the protocol, an uplink transmission instructed by the network side, or an uplink transmission determined by the terminal.
[0120] In some implementations, the second uplink transmission includes at least one of the following:
[0121] the most recent uplink transmission sent by the terminal before sending the first uplink transmission;
[0122] an uplink transmission most recently sent by the terminal before a first time, where the first time is before the sending of the first uplink transmission and is separated from the sending of the first uplink transmission by a first duration;
[0123] The uplink transmission is scheduled or triggered by a first signaling, where the first signaling is used to schedule or trigger the first uplink transmission.
[0124] The uplink transmission most recently sent by the terminal before sending the first uplink transmission refers to the uplink transmission most recently sent by the terminal before the first uplink transmission.
[0125] The most recent uplink transmission sent by the terminal before the first time refers to the latest uplink transmission sent by the terminal before the first time.
[0126] The above-mentioned first duration may be a protocol agreement or a network side configuration, or the above-mentioned first duration may be predefined or determined by a predefined rule, such as determined according to a subcarrier (SCS), or the above-mentioned first duration may be related to the terminal capability, such as a first duration determined according to the terminal capability, such as a first duration determined according to the terminal reporting capability.
[0127] The first signaling may be DCI or other downlink signaling, for example, DCI or downlink signaling that triggers the first uplink transmission and other uplink transmissions simultaneously.
[0128] In the above embodiment, the transmission power control parameters of the first uplink transmission can be determined by offsetting the transmission power control parameters relative to the above multiple uplink transmissions, so as to improve the flexibility of the transmission power control parameters of the first uplink transmission and save configuration overhead.
[0129] In some embodiments, the above-mentioned offset can be an offset of the transmission power, or an offset of the power control parameter. For example, normal PUCCH / PUSCH transmission will have its own power control parameter, such as P0. The network side device can also configure an offset relative to P0 of PUCCH / PUSCH, and determine the P0 used for the first uplink transmission through the P0 of normal PUCCH / PUSCH and the offset.
[0130] Optionally, the second uplink transmission includes at least one of the following:
[0131] Uplink transmission sent on the target beam;
[0132] Uplink transmissions sent at target antenna panels;
[0133] Uplink transmissions sent at the target TRP.
[0134] The above-mentioned target beam can be one or more specific beams, such as a beam agreed upon by the protocol or configured on the network side, or a beam determined by the terminal.
[0135] The target beam may be one or more specific antenna panels, such as antenna panels agreed upon by the protocol or configured on the network side, or antenna panels determined by the terminal.
[0136] The above-mentioned target beam can be a specific one or more TRPs, such as the TRP agreed upon by the protocol or configured on the network side, or the TRP determined by the terminal.
[0137] In some embodiments, the second uplink transmission may be the uplink transmission most recently sent by the terminal on the target beam, target antenna panel, or target TRP before sending the first uplink transmission. For example, the second uplink transmission may be the uplink transmission most recently sent by the terminal on the target beam, target antenna panel, or target TRP before the first time.
[0138] In some embodiments, the target beam, target antenna panel or target TRP may be the same as the beam, antenna panel or TRP of the first uplink transmission, so as to determine the transmission power control parameters of the first uplink transmission with reference to the same beam, antenna panel or TRP, so that the transmission power control parameters of the first uplink transmission are more accurate.
[0139] Optionally, the first downlink transmission includes at least one of the following:
[0140] the downlink transmission most recently received by the terminal before sending the first uplink transmission;
[0141] a downlink transmission most recently received by the terminal before a second time, where the second time is before the first uplink transmission is sent and is separated from the sending of the first uplink transmission by a second time interval;
[0142] The downlink transmission scheduled by the downlink signaling that triggers the first uplink transmission.
[0143] The above-mentioned second duration may be a protocol agreement or a network-side configuration, or the above-mentioned second duration may be predefined or determined by a predefined rule, such as determined according to the SCS, or the above-mentioned second duration may be related to the terminal capability, such as a second duration determined according to the terminal capability, such as a second duration determined according to the terminal reporting capability.
[0144] The above downlink signaling may be used to schedule downlink transmission and also be used to trigger self-interference measurement.
[0145] In the above implementation, the transmission power control parameters of the first uplink transmission can be determined by offsetting the transmission power control parameters relative to the above multiple downlink transmissions, so as to improve the flexibility of the transmission power control parameters of the first uplink transmission and save configuration overhead.
[0146] Optionally, the first downlink transmission includes at least one of the following:
[0147] downlink transmission received on the target beam;
[0148] downlink transmissions received at the target antenna panel;
[0149] Downlink transmissions received at the target TRP.
[0150] Associates the downlink transmission of the target CORESET pool index.
[0151] The above-mentioned target beam, target antenna panel or target TRP refers to the corresponding description of the above-mentioned embodiment and will not be repeated here.
[0152] The target CORESET pool index may be determined by protocol agreement, network configuration, or terminal, and the target CORESET pool index may be associated with the target TRP.
[0153] In some embodiments, the first downlink transmission may be the downlink transmission that the terminal last received on the target beam, target antenna panel, or target TRP before sending the first uplink transmission. For example, the second uplink transmission may be the downlink transmission that the terminal last received on the target beam, target antenna panel, or target TRP before the second time.
[0154] In some embodiments, the terminal may also determine whether the terminal applies the first power offset or the second power offset for the above-mentioned first uplink transmission based on a predefined rule or a network-side indication. For example: for a non-periodic or network-side scheduled first uplink transmission, whether to apply the above-mentioned first power offset or the second power offset is determined based on the network's internal indication; for a periodic or semi-statically configured first uplink transmission, the above-mentioned first power offset or the second power offset is applied, or the base station configures whether to apply the above-mentioned first power offset or the second power offset. For another example: only the first uplink transmission specifically triggered for self-interference measurement applies the above-mentioned first power offset or the second power offset; for other first uplink transmissions, the above-mentioned first power offset or the second power offset is not applied. For another example: whether to apply the above-mentioned first power offset or the second power offset is determined based on DCI or MAC CE or RRC indication.
[0155] Optionally, when the transmission power control parameter configured by the network side for the first uplink transmission obtained by the terminal includes a transmission power control parameter of the first uplink transmission corresponding to at least one resource interval, the terminal sending the first uplink transmission based on the transmission power control parameter includes:
[0156] The terminal sends the first uplink transmission based on the transmission power control parameter of the first uplink transmission corresponding to the target interval;
[0157] The target interval includes at least one of the following:
[0158] The interval between semi-statically configured uplink frequency resources and downlink frequency resources;
[0159] The interval between dynamically scheduled uplink frequency resources and downlink frequency resources.
[0160] The transmission power control parameter for the first uplink transmission corresponding to the at least one resource interval may be a transmission power control parameter for the first uplink transmission configured differently for different resource intervals, for example: (gap1, p1), (gap2, p2), i.e., transmission power control parameter 1 is configured for resource interval 1, and transmission power control parameter 2 is configured for resource interval 2.
[0161] In this implementation, the transmission power control parameter of the first uplink transmission can be determined based on a semi-static configuration or a dynamic scheduling interval, so that the transmission power control parameter of the first uplink transmission is more matched with the frequency resource, thereby improving the self-interference measurement performance.
[0162] Optionally, when the transmission power control parameter configured by the network side for the first uplink transmission obtained by the terminal includes a transmission power control parameter of the first uplink transmission corresponding to at least one transmission configuration parameter, the terminal sending the first uplink transmission based on the transmission power control parameter includes:
[0163] The terminal sends the first uplink transmission based on the transmission power control parameter of the first uplink transmission corresponding to the target transmission configuration parameter in the at least one transmission configuration parameter;
[0164] The target transmission configuration parameter includes at least one of the following:
[0165] Semi-statically configured transmission configuration parameters;
[0166] Dynamically scheduled transmission configuration parameters.
[0167] The transmission power control parameter of the first uplink transmission corresponding to the at least one transmission configuration parameter may be a transmission power control parameter corresponding to different transmission configuration parameters.
[0168] In this embodiment, the transmission power control parameters of the first uplink transmission can be determined based on the semi-statically configured or dynamically scheduled transmission configuration parameters, so that the transmission power control parameters of the first uplink transmission are more closely matched with the transmission configuration, thereby improving self-interference measurement performance. It will be understood that the semi-statically configured transmission configuration parameters may be transmission configuration parameters determined based on semi-static configuration information of the terminal, and the dynamically scheduled transmission configuration parameters may be transmission configuration parameters determined based on dynamic scheduling information.
[0169] Optionally, the transmission power control parameter of the first uplink transmission includes: multiple sets of transmission power control parameters, and the terminal sending the first uplink transmission based on the transmission power control parameters includes:
[0170] The terminal sends the first uplink transmission multiple times based on multiple sets of transmission power control parameters; or
[0171] The terminal sends the first uplink transmission based on a target transmission power control parameter, where the target transmission power control parameter is a transmission power control parameter indicated by the network side and obtained by the terminal and indicated in the multiple sets of transmission power control parameters.
[0172] The multiple sets of transmission power control parameters may determine multiple transmission powers. For example, the multiple sets of transmission power parameters may include at least one of the following:
[0173] Multiple power offsets, transmission power control parameters for multiple resources, transmission power control parameters for multiple resource intervals, transmission power control parameters for multiple transmission configurations.
[0174] For example, if the transmission power control parameters include multiple resource intervals, the terminal may send the first uplink transmission according to different resource intervals and their corresponding powers at different times (such as time units such as time slots, symbols, or subframes) to perform multiple self-interference measurements, or send the first uplink transmission using only the power corresponding to one resource interval to perform one self-interference measurement.
[0175] For another example, multiple power offsets are included so that the terminal can send the first uplink transmission multiple times on the same measurement resource (at different times) to perform multiple self-interference measurements, or only use one power offset to send the first uplink transmission once to perform one self-interference measurement.
[0176] For another example: each beam, antenna panel or TRP can be configured with one or more transmission power control parameters, so that the terminal sends the first uplink transmission in each beam, antenna panel or TRP and the corresponding power to perform multiple self-interference measurements, or only uses one beam, antenna panel or TRP and the corresponding power to send the first uplink transmission once to perform one self-interference measurement.
[0177] In the above implementation, one or more self-interference measurements may be implemented to improve the flexibility of the self-interference measurement. Multiple self-interference measurements may make the self-interference measurement more accurate, while one self-interference measurement may save terminal power consumption and resource overhead.
[0178] Optionally, the measurement result includes: a self-interference strength indication, and at least one of the following:
[0179] Measurement resource information, transmit power, frequency interval, beam information, antenna panel information, TRP information, spatial information, CORESET pool index.
[0180] The self-interference strength indicator may be at least one of RSSI, RSRP, RSRQ, L1-SINR, etc. In some embodiments, the self-interference strength indicator may be residual SI, which refers to the SI remaining after the terminal performs self-interference cancellation, such as the SI obtained by re-measurement after the terminal performs self-interference cancellation. The self-interference strength or residual self-interference strength may be represented by different metrics such as RSSI, RSRP, RSRQ, L1-SINR, etc.
[0181] The above-mentioned measurement resource information, transmit power, frequency interval, beam information, antenna panel information, TRP information, space information, and CORESET pool index are the measurement resource information, transmit power, frequency interval, beam information, antenna panel information, TRP information, space information, and CORESET pool index associated with the above-mentioned first uplink transmission; or, the above-mentioned measurement resource information, transmit power, frequency interval, beam information, antenna panel information, TRP information, space information, and CORESET pool index are the measurement resource information, transmit power, frequency interval, beam information, antenna panel information, TRP information, space information, and CORESET pool index associated with the above-mentioned self-interference measurement.
[0182] In this implementation, more accurate and detailed measurement results can be reported, so that the network-side device can better handle communications with the terminal.
[0183] In one embodiment, when a certain uplink signal / data / channel for self-interference measurement of a terminal is configured with different transmission powers, the terminal transmits the self-interference measurement uplink signal / data / channel at different times (e.g., times determined according to a base station instruction or a predefined rule) according to the different transmission powers and performs self-interference measurement in a downlink subband (DL subband), respectively. The terminal can report the self-interference measurement result corresponding to each power. For example, the terminal reports all or part of the contents of the following Table 1, such as {ID, transmit power (Tx power), frequency gap (Frequency gap), beam (beam), RSSI value (RSSI value)}, or {ID, Tx power, RSSI value} to the network side device. Alternatively, the power used by the terminal for each transmission of a self-interference measurement uplink signal / data / channel is determined according to a predefined rule (for example, the first transmission is based on the configured first power, the second transmission is based on the configured second power, ..., the Nth transmission is based on the configured last power, and then, if necessary, the power is re-configured from the first configured power (for example, if the terminal does not need to send the self-interference measurement uplink signal / data / channel (in the current cycle / window) again, the cycle may not be repeated)). When reporting, for the same self-interference measurement resource, the terminal may report the self-interference measurement amount corresponding to one transmission power at a time, or report the self-interference measurement amounts corresponding to multiple configured transmission powers.
[0184] Table 1:
[0185] It should be noted that the above Table 1 is only an example of a measurement result, and the embodiments of the present application do not limit the specific content or form of the measurement results.
[0186] In some implementations, the measurement result may also only include the self-interference strength indication.
[0187] In some embodiments, the above-mentioned measurement results may not include the above-mentioned self-interference strength indication. For example, the above-mentioned measurement results may be used to indicate whether the self-interference measurement meets the target condition, and the target condition is known to the network side device. In this way, through the indication of the measurement result, the network side device can also be aware of the terminal self-interference situation.

By reporting the measurement result of the self-interference measurement to the network-side device, it is possible to avoid the problem of communication between the terminal and the network-side device being affected by the network-side device being unable to obtain the terminal's interference performance, thereby facilitating improved communication performance between the terminal and the network-side device.

[0219] It should be noted that this embodiment is an implementation of the network side device corresponding to the embodiment shown in Figure 4. Its specific implementation can refer to the relevant description of the embodiment shown in Figure 4. In order to avoid repeated description, this embodiment will not be repeated.
[0220] The method provided in the embodiment of the present application is illustrated below by an example:
[0221] The network side device configures the transmission power control parameters of the uplink signal / data / channel (i.e., the above-mentioned first uplink transmission), wherein the uplink signal / data / channel is used by the terminal to perform self-interference measurement or self-interference measurement and reporting. The configuration may include at least one of the following:
[0222] Method 1: The network-side device configures independent power control parameters for uplink signals / data / channels used for self-interference measurement, such as power control parameter 0 (loop 0, which may include one or more parameters and may be understood as a set of power control parameters) independent of transmission power control parameter 1 (loop 1, which may include one or more parameters and may be understood as a set of power control parameters) for uplink transmission (e.g., PUCCH / PUSCH / SRS / PRACH).
[0223] Optionally, the power control parameter set (i.e., loop 0 or loop 1) used by a self-interference measurement uplink signal / data / channel is determined according to a predefined rule or an indication from a network-side device, for example:
[0224] For uplink signals / data / channels (such as PUCCH / PUSCH / SRS) with aperiodic or network-scheduled self-interference measurement, the power control parameters (i.e., loop or loop 1) indicated by the network (e.g., indicated by DCI) are used. For uplink signals / data / channels (such as PUCCH / PUSCH / SRS) with periodic or semi-static self-interference measurement, the independent power parameters for self-interference measurement (i.e., loop 0) or the power control parameters configured by the network (i.e., loop 0 or loop 1) are used.
[0225] Only uplink signals / data / channels specifically triggered for self-interference measurement, such as specific SRS, use independent power parameters. For other self-interference measurement signals, namely PUCCH / PUSCH / SRS that are normally scheduled or periodically transmitted (i.e., used not only for self-interference measurement but also for normal uplink transmission), the original power parameters are used.
[0226] Which set of parameters to use is indicated based on DCI or MAC CE or RRC.
[0227] Method 2: The network-side device configures a power offset (power offset) of 1. The power offset 1 represents the offset of the transmission power (or transmission power control parameter, or EPRE) of the self-interference measurement uplink signal / data / channel relative to a certain uplink transmission, such as PUCCH / PUSCH / SRS / PRACH.
[0228] The uplink transmission may be determined by a predefined rule, for example:
[0229] The terminal measures the self-interference of the uplink signal / data / channel before the last transmission of the PUCCH / PUSCH / SRS / PRACH before T0, or;
[0230] The most recently transmitted PUCCH / PUSCH / SRS / PRACH on a specific beam / panel / TRP before T0 before the transmission of the uplink signal / data / channel for self-interference measurement. The specific beam can be one or more, for example, the same beam / panel / TRP as the uplink signal / data / channel for self-interference measurement.
[0231] Or it is a DCI-scheduled uplink transmission that triggers the terminal to transmit the uplink signal / data / channel for self-interference measurement, that is, scheduling DCI-scheduled uplink transmission (which may be PUCCH) while triggering the terminal to perform self-interference measurement.
[0232] T0 can be predefined / determined by predefined rules (for example, determined according to the SCS terminal capabilities) or related to the terminal capabilities (terminal reporting), and T0 can be a duration of 0 or greater than 0.
[0233] For each uplink signal / data / channel for self-interference measurement, multiple loop 0s can be configured. When multiple power offsets are configured, the terminal can measure the same measurement resource multiple times (at different times).
[0234] Alternatively, different uplink channels / signals can be configured with different power offsets.
[0235] Optionally, whether a UE applies power offset 1 for a self-interference measurement uplink signal / data / channel is determined according to a predetermined rule or an indication of a network-side device, for example:
[0236] For uplink signals / data / channels (such as PUCCH / PUSCH / SRS) with non-periodic or network-side device-scheduled self-interference measurement, the network-side device indication (such as through DCI indication) is used to determine whether to apply. For uplink signals / data / channels (such as PUCCH / PUSCH / SRS) with periodic or semi-static self-interference measurement, the above-mentioned power offset 1 is applied, or the network-side device configures whether to apply it.
[0237] The power offset parameter is only applied to uplink signals / data / channels specifically triggered for self-interference measurement, such as specific SRS. The power offset 1 is not applied to other self-interference measurement signals, namely, PUCCH / PUSCH / SRS that are normally scheduled or periodically transmitted (i.e., used not only for self-interference measurement but also for normal uplink transmission).
[0238] Whether to apply the power offset 1 is determined based on DCI, MAC CE, or RRC.
[0239] Method 3: The network side device configures power offset 2, where power offset 2 indicates the offset of the uplink signal / data / channel for self-interference measurement relative to the downlink received power (or EPRE), or the offset of the downlink received power of the DCI-scheduled downlink transmission that triggers the terminal to transmit the uplink signal / data / channel for self-interference measurement, that is, the terminal is triggered to perform self-interference measurement while scheduling the DCI-scheduled downlink transmission.
[0240] Among them, the above-mentioned downlink reception can be determined by predefined rules, such as the PDCCH / PDSCH / CSI-RS / SSB most recently received by the terminal before T1 before performing self-interference measurement of uplink signal / data / channel transmission; wherein T1 can be determined by predefined / predefined rules (for example, determined according to SCS, at least one of the terminal capabilities) or related to the terminal capabilities (terminal reporting).
[0241] For each self-interference measurement uplink signal / data / channel, multiple power offset 2s can be configured. When multiple power offset 2s are configured, the terminal can measure the same measurement resource (at different times) multiple times.
[0242] Alternatively, different uplink channels / signals can be configured with different power offset2.
[0243] Optionally, whether a UE applies power offset 2 for a self-interference measurement uplink signal / data / channel is determined according to a predefined rule or an indication from a network-side device, for example:
[0244] For uplink signals / data / channels (such as PUCCH / PUSCH / SRS, etc.) of non-periodic or network-side device-scheduled self-interference measurement, the network-side device indication (such as through DCI indication) is used to determine whether to apply it. For uplink signals / data / channels (such as PUCCH / PUSCH / SRS, etc.) of periodic or semi-statically configured self-interference measurement, the above-mentioned power offset 2 is applied, or the network-side device configures whether to apply it.
[0245] The power offset parameter is only applied to uplink signals / data / channels specifically triggered for self-interference measurement, such as specific SRS. Power offset 2 is not applied to other self-interference measurement signals, namely, PUCCH / PUSCH / SRS that are normally scheduled or periodically transmitted (i.e., used not only for self-interference measurement but also for normal uplink transmission).
[0246] Whether to apply the above-mentioned power offset 2 is based on DCI, MAC CE or RRC indication.
[0247] Method 4: The network-side device configures / indicates the transmission power control parameters (including power offset) of the uplink signal / data / channel for self-interference measurement at the granularity of SI-RS resources (i.e., per SI-RS resource). Among them, SI-RS resources can also be called self-interference measurement resources.
[0248] Each self-interference measurement uplink signal / data / channel may be configured with one or more sets of power control parameters.
[0249] Method 5: The network-side device configures / indicates the transmission power control parameters (including power offset) of the uplink signal / data / channel for self-interference measurement with a resource interval as the granularity (i.e., per gap). The resource interval can be the frequency domain interval between the DL subband and the UL subband, where the subband can be one or more continuous or discontinuous PRBs (also referred to as resource blocks (RB) sets or RB groups (RB group) etc.) in the frequency domain. The DL subband and UL subband are subbands used for downlink and uplink transmission, respectively.
[0250] The terminal determines the transmission power control parameters of the uplink signal / data / channel for self-interference measurement based on the gap between the semi-statically configured DL / UL, or
[0251] The terminal determines the transmission power control parameters of the uplink signal / data / channel for self-interference measurement based on the gap between the dynamically scheduled DL / UL transmissions, or
[0252] The terminal sends self-interference measurement uplink signals / data / channels at different times (such as time slots or symbols) according to different DL / UL gaps and their corresponding powers, and reports them to the network side device (in a defined order, or indicating the corresponding gap when reporting SI).
[0253] Optionally, each gap can be configured with one or more powers.
[0254] Method 6: Configure / indicate the transmission power control parameters (including power offset) of the uplink signal / data / channel for self-interference measurement at the transmission configuration granularity (such as per beam / pannel / TRP / spatial information / QCL). The beam can be a UL Tx beam or a DL Rx beam.
[0255] The terminal determines the transmission power control parameters of the uplink signal / data / channel for self-interference measurement based on the semi-statically configured beam / pannel / TRP, or
[0256] The terminal determines the transmission power control parameters of the uplink signal / data / channel for self-interference measurement based on the dynamically scheduled beam / pannel / TRP, or
[0257] The terminal sends self-interference measurement uplink signals / data / channels at different times (such as time slots or symbols) according to different beams / pannels / TRPs and their corresponding powers, and reports them to the network side device. The corresponding beam / pannel / TRP can be indicated in the defined order or when reporting SI.
[0258] Optionally, each beam / pannel / TRP can be configured with one or more power levels.
[0259] The transmission power control parameter may include at least one of the following: P0, alpha, and power offset, where P0 is the target received power and alpha is the path loss compensation factor.
[0260] In some implementations, the network-side device may configure one or more transmit powers for the terminal. When multiple transmit powers are configured, the terminal adopts the following method:
[0261] For a certain uplink signal / data / channel for self-interference measurement, the network side device instructs the terminal to adopt one of them. For example, the network side device indicates one of multiple configured powers when triggering the terminal to perform self-interference measurement; or
[0262] For a certain self-interference measurement uplink signal / data / channel, the UE transmits the same self-interference measurement uplink signal / data / channel at different times according to different powers among multiple powers, and reports its corresponding self-interference measurement and its corresponding power. For example: the terminal transmits the self-interference measurement uplink signal / data / channel in different periods, or at different positions in the same period, or at different positions after triggering, in sequence according to different configured transmission powers, and performs self-interference measurement and reports it; or
[0263] When the transmission power control parameter of a self-interference measurement channel / signal is not configured, the terminal transmits the self-interference measurement uplink signal / data / channel according to the power determined by the default value / predefined value / predefined rule, and performs self-interference measurement in the DL subband.
[0264] The embodiment of the present application provides a power control for a terminal operating in full-duplex mode, which is used to measure and report self-interference, so that the network side equipment can accurately obtain the self-interference situation of the terminal when operating in full-duplex mode, thereby improving the effectiveness of the communication system.
