Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a measurement method, a measurement resource configuration method, a device and a communication device. Background Art

[0002] Full duplex transmission technology is introduced in the New Radio (NR) system. Currently, only the network side supports full duplex transmission, and the terminal (User Equipment, UE, also known as user equipment) side supports half duplex transmission. That is to say, the network side can send downlink (DL) signals (or channels) and receive uplink (UL) signals (or channels) simultaneously in one time unit (such as a time slot or symbol), while the UE can only send UL signals (or channels) or receive DL signals (or channels) in one time unit.

[0003] If the UE side supports full-duplex transmission, the UE can send and receive simultaneously within one time unit. However, when the UE sends and receives simultaneously, different degrees of self-interference (SI) will be generated. Since the UE side currently only supports half-duplex transmission, the influence of self-interference does not need to be considered for half-duplex transmission on the UE side. For the case where the UE side supports full-duplex transmission, due to the influence of self-interference, if the measurement is still performed according to the measurement scheme of half-duplex transmission, the channel state information (CSI) measured by the UE will have a large deviation.

As long as the same technical effect is achieved, the base station is not limited to specific technical terms. 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.

[0050] Before describing the embodiments of the present application, the following briefly introduces the related technologies:

[0051] Compared with previous mobile communication systems, future 5G mobile communication systems need to adapt to more diverse scenarios and business requirements. The main scenarios of 5G include enhanced mobile broadband (eMBB), ultra reliable and low latency communication (URLLC), and massive machine type communication (mMTC, also known as large-scale Internet of Things services). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage.

[0052] In NR, configuring full-duplex operation can significantly improve the latency and coverage performance of the Time Division Duplex (TDD) system. Full-duplex can include, for example, subband full duplex (SBFD) and subbands non-overlapping Full duplex.

[0053] In the half-duplex scenario, for a DL slot (e.g., configured by the parameter "tdd-UL-DL-ConfigurationCommon" or the parameter "tdd-UL-DL-ConfigurationDedicated"), the network side device configures the DL bandwidth part (Bandwidth Part, BWP) for the UE. For a UL slot (e.g., configured by the parameter "tdd-UL-DL-ConfigurationCommon" or the parameter "tdd-UL-DL-ConfigurationDedicated"), the network configures the UL BWP for the UE.

[0054] like Figure 2 As shown in the figure, in a full-duplex scenario, for a DL slot, the following situations are included:

[0055] Case 1: DL BWP is configured, that is, DL slot 1.

[0056] Case 2: DL BWP and UL sub-band are configured, namely, DL slot 2.

[0057] like Figure 3 As shown in the figure, in a full-duplex scenario, for a UL slot, the following situations are included:

[0058] Case 3: Configure UL BWP, that is, UL slot 4.

[0059] Case 4: Configure UL BWP and DL sub band, that is, UL slot 5.

[0060] For SBFD operation, one SBFD subband is composed of one resource block (RB) or a set of consecutive RBs with the same transmission direction. The time unit (eg, slot or symbol) in which the base station uses SBFD operation may be referred to as a SBFD time unit (eg, slot or symbol).

[0061] like Figure 4 As shown in the figure, for Rel-15, the base station and UE can only send or receive at one time. For Rel-18, the gNB side is full duplex (GNB FD), the gNB can send and receive at the same time; the UE side can only use half duplex mode, that is, it can only send or receive at one time. For full duplex on the UE side (UE FD), the gNB and UE can send and receive at the same time.

[0062] To simplify the description, the following two full-duplex modes can be defined:

[0063] Network full-duplex mode: full-duplex is applied on the network side, and half-duplex is applied on the UE side. Half-duplex on the UE side means that the UE can only receive DL signals (or channels) or send UL signals (or channels) in one time unit.

[0064] Terminal full-duplex mode: Full-duplex is applied on the network side and full-duplex is applied on the UE side. Full-duplex on the UE side means that the UE receives DL signals (or channels) and sends UL signals (or channels) simultaneously in one time unit.

[0065] The network full-duplex mode can achieve the purpose of enhancing coverage, reducing transmission delay, and improving resource utilization efficiency. The terminal full-duplex mode can improve DL (and UL) throughput while achieving the above gains.

[0066] like Figure 5 As shown, for a communication device, simultaneous UL transmission and DL transmission will cause self-interference. In order to ensure transmission in the interfered direction, the communication device needs to have the ability to eliminate self-interference. For example, a guard band (GB) is reserved between the receiving band and the transmitting band to achieve frequency isolation and reduce self-interference. In addition, since the UE's self-interference elimination capability is usually weaker than that of the gNB, for simultaneous transmission and reception on the UE side, the GB that needs to be reserved is larger than that on the gNB side, that is, more physical resource blocks (PRBs) are required to be reserved as guard bands to suppress self-interference.

[0067] like Figure 5 As shown, (a) is the subband and GB configuration of full-duplex on the network side, that is, the network side device configures the time-frequency resources of UL subband, DL subband and GB. In the UL subband, the network side device receives the UL channel or signal of the served UE, and in the DL subband, the network side device sends the DL channel or signal to the served UE. The DL transmission of the network side device will cause self-interference to the UL reception of the network side device. (b) is the subband and GB configuration of full-duplex on the UE side, that is, the network side device configures the UL subband, DL subband and GB time-frequency resources for the UE, and the UL transmission of the UE will cause self-interference to the DL reception of the UE. In addition, the capabilities of different UEs may be different, so the GBs that need to be reserved may also be different.

[0068] Currently, only the network side supports full-duplex transmission, while the terminal (User Equipment, UE, also known as user equipment) side supports half-duplex transmission. That is, the network side can simultaneously send downlink (DL) signals (or channels) and receive uplink (UL) signals (or channels) in one time unit (such as a time slot or symbol), while the UE can only send UL signals (or channels) or receive DL signals (or channels) in one time unit.

[0069] If the UE side supports full-duplex transmission, the UE supports simultaneous transmission and reception, that is, the UE can simultaneously receive DL signals (or channels) and send UL signals (or channels) within one time unit. In this way, the UE can maintain high UL and DL performance (such as throughput) while obtaining coverage gain and latency reduction. For UEs that support simultaneous transmission and reception, when the UE performs simultaneous transmission and reception, the UL signal (or channel) will generate self-interference to the reception of the DL signal (or channel), which will affect the performance of the UE. However, the current CSI does not include relevant information about self-interference, and the CSI calculated by the UE has a large deviation. Specifically, the channel quality indicator (CQI) in the CSI has a large deviation. The network side device needs to perform scheduling based on the CSI (or CQI) reported by the UE. If the CSI (or CQI) reported by the UE has a large deviation, it will be detrimental to the scheduling of the network side device.

[0070] In view of this, an embodiment of the present application provides a measurement method, a measurement resource configuration method and a device to support full-duplex transmission on the UE side.

[0071] The following, in conjunction with the accompanying drawings, describes in detail the measurement method, measurement device, measurement resource configuration method, and measurement resource configuration device provided in the embodiments of the present application through some embodiments and their application scenarios.

[0072] Figure 6 A flow chart of a measurement method provided by an embodiment of the present application is shown. Figure 6 As shown, the measurement method includes the following steps:

[0073] Step 601: The terminal performs uplink transmission in a first resource and performs interference measurement in a second resource, wherein the first resource is an uplink resource of full-duplex transmission of the terminal, the second resource is a downlink resource of full-duplex transmission of the terminal, and a time domain where the second resource is located overlaps with a time domain where the first resource is located;

[0074] Step 602: The terminal reports CSI to the network side device according to the result of the interference measurement and the channel measurement result of the third resource, where the third resource is a resource for channel measurement corresponding to the second resource.

[0075] The interference measurement on the second resource includes: measuring the interference caused by the uplink transmission of the first resource on the second resource. That is, the uplink transmission on the first resource will cause interference on the second resource. It is worth noting that the interference on the second resource may also include interference caused by transmission of other terminals or base stations.

[0076] In an embodiment of the present application, the uplink resources and downlink resources of the terminal's full-duplex transmission are determined by assuming that the GB size is the GB size of full-duplex operation on the network side. In the drawings of each embodiment involved in the embodiment of the present application, the GB size is assumed to be the GB size of full-duplex operation on the network side.

[0077] In the embodiment of the present application, the UE may calculate the CSI according to the channel measurement result and the interference measurement result and report it to the network side device. The CSI reported by the UE to the network side device may include CQI and other parameters. Taking CQI as an example, CQI is an indicator reflecting the quality of the downlink channel and is the basis for downlink scheduling. In the related art, in the UE half-duplex mode, the UE performs channel measurement and interference measurement on the downlink resources configured by the network side device, and the downlink resources include channel measurement resources (Channel Measurement Resource, CMR) and interference measurement resources (Interference Measurement Resource, IMR), etc. In the UE full-duplex mode, the UE can transmit and receive downlink resources and uplink resources at the same time. The signal sent by the UE in the uplink resource will leak to the downlink resource to form self-interference (such as harmonic interference or intermodulation interference). Therefore, if the UE still performs channel measurement and interference measurement on the downlink resources configured by the network side device in the half-duplex mode, the CSI obtained thereby will ignore the impact of self-interference on the channel quality, resulting in a large deviation in the CSI measured by the UE. Then, the service scheduling performed by the network side device on the UE based on the CSI may not be appropriate.

[0078] In an embodiment of the present application, the terminal performs uplink transmission in the first resource, and performs interference measurement in the second resource, and the time domain where the second resource is located overlaps with the time domain where the first resource is located. Since the time domains where the two are located overlap, when the terminal performs uplink transmission in the first resource, the uplink signal will be leaked to the second resource as an interference signal (since the interference signal comes from the terminal itself, it can be called a self-interference signal). In addition, when the terminal performs interference measurement in the second resource, the interference measured by the terminal in the second resource may include interference from other communication devices in addition to the interference from the terminal itself (i.e., self-interference). It can be seen that by performing uplink transmission in the first resource and performing interference measurement in the second resource, the interference measurement actually includes the measurement of self-interference, and thus, the result of the interference measurement also includes the result of the self-interference measurement. The CSI calculated by the terminal also includes the self-interference suppression capability of the terminal, or in other words, the CSI calculated by the terminal can reflect the impact of the terminal's self-interference on the channel state.

[0079] For the network side device, since the CSI reported by the terminal can reflect the impact of the terminal's self-interference on the channel state, the network side device can perform appropriate service scheduling for the terminal based on the CSI reported by the terminal.

[0080] In an embodiment of the present application, the terminal performs uplink transmission on the first resource, and performs interference measurement on the second resource, the first resource is the uplink resource of the full-duplex transmission of the terminal, the second resource is the downlink resource of the full-duplex transmission of the terminal, and the time domain where the second resource is located overlaps with the time domain where the first resource is located; the terminal reports CSI to the network side device according to the result of the interference measurement and the channel measurement result of the third resource. Through the above process, the interference measurement result of the terminal includes the interference situation of self-interference, and the CSI reported by the terminal to the network side device can also reflect the degree of self-interference of the full-duplex resource, so that the network side device can perform appropriate service scheduling for the terminal based on the CSI reported by the UE. It can be seen that the measurement scheme of the embodiment of the present application can be applied to the full-duplex transmission scenario on the UE side, which is conducive to supporting full-duplex transmission on the UE side.

[0081] Optionally, the terminal performing uplink transmission on the first resource includes:

[0082] The terminal performs uplink transmission on the first resource based on the transmission parameters configured by the network side device;

[0083] The transmission parameter includes at least one of a bandwidth parameter, a spatial domain parameter and a power parameter.

[0084] In this implementation, by configuring relevant transmission parameters through the network side device, the network side device is helped to know the degree of influence of self-interference on the channel state under different transmission parameters, thereby helping the network side device to determine appropriate transmission parameters in subsequent scheduling.

[0085] In an embodiment of the present application, the first resource, the second resource and the third resource are all resources configured (or scheduled) by the network side device. For ease of understanding, the first resource is called a self-interference resource (SI resoruce, SIR) or a self-interference generating resource, the second resource is called an interference measurement resource, and the third resource is called a channel measurement resource.

[0086] Since the time domain where the second resource is located overlaps with the time domain where the first resource is located, the first resource and the second resource can be configured (or scheduled) by the network side device in the form of a resource pair. Therefore, the first resource and the second resource can be called a resource pair for self-interference measurement, and the first resource and the second resource can be represented as an {interference measurement resource, self-interference resource} pair or an {interference measurement resource, self-interference resource} resource pair.

[0087] The interference measurement resources and self-interference resources configured (or scheduled) by the network side device can be resources used for channel transmission or resources used for signal transmission. For the terminal, the terminal triggers the {interference measurement resource, self-interference resource} resource pair including sending the self-interference channel (or signal) in the UL subband and performing interference measurement in the DL subband.

[0088] The interference measurement resources may include resources for receiving a demodulation reference signal (DMRS), where the DMRS may include, for example, a DMRS of a physical downlink shared channel (PDSCH), a DMRS of a physical downlink control channel (PDCCH), or resources for receiving a CSI reference signal (CSI-RS), such as a non-zero power CSI-RS (Non-Zero Power CSI-RS, NZP CSI-RS) resource, a CSI interference measurement (CSI-IM) resource, or certain PDSCH resource elements (REs) configured by a network side device.

[0089] Self-interference resources (SI resources for short) can be resources used to send sounding reference signals (SRS), physical uplink control channels (PUCCH) or physical uplink shared channels (PUSCH), etc. When the SI resource is PUSCH, if there is no medium access control (MAC) protocol data unit (PDU), PUSCH can use dummy bits, which can be generated by the physical layer or the MAC layer. When the SI resource is PUCCH, PUCCH can report dummy bits or scheduling request (SR) information. For channels that transmit dummy bits, network-side devices do not need to decode them, which is beneficial to reduce the communication overhead of network-side devices.

[0090] As an example, the resource pair may include {CSI-IM-ResourceForInterference, SRSresource}, {CSI-IM-ResourceForInterference, PUSCH resource}, {CSI-IM-ResourceForInterference, PUCCH resource}, {nzp-CSI-RS-ResourcesForInterference, SRS resource}, {nzp-CSI-RS-ResourcesForInterference, PUSCH resource} or {nzp-CSI-RS-ResourcesForInterference, PUCCH resource}, etc. Among them, CSI-IM-ResourceForInterference indicates CSI-IM resources used for interference measurement, and nzp-CSI-RS-ResourcesForInterference indicates NZP CSI-RS resources used for interference measurement.

[0091] For a terminal, optionally, the terminal performs uplink transmission on a first resource, including at least one of the following:

[0092] The terminal sends an SRS on the first resource;

[0093] The terminal sends a PUCCH on the first resource;

[0094] The terminal sends a PUSCH on the first resource.

[0095] Optionally, the SRS carries a target identifier, and the target identifier is used to indicate that the SRS is used for self-interference measurement. The target identifier can be expressed as "SRS usage for SI measurement", specifically, "usageSI measurement ENUMERATED{true}". In this way, the function of the SRS can be better distinguished, and the network side device does not need to decode the SRS carrying the target identifier, thereby reducing the communication overhead of the network side device.

[0096] For the terminal, optionally, the terminal performs interference measurement on the second resource, including at least one of the following:

[0097] The terminal receives a DMRS on the second resource;

[0098] The terminal receives a CSI-RS on the second resource.

[0099] The third resource may be configured (or scheduled) together with the {interference measurement resource, self-interference resource} resource pair, or may not be configured (or scheduled) together with the {interference measurement resource, self-interference resource} resource pair. That is to say, the channel measurement of the third resource and the interference measurement of the second resource may be performed in the same measurement event, or may be performed in different measurement events respectively. The time domain where the third resource is located may be before the time domain where the {interference measurement resource, self-interference resource} resource pair is located, or may be after the time domain where the {interference measurement resource, self-interference resource} resource pair is located.

[0100] As an example, the channel measurement result of the third resource can be obtained before the network side device configures the {interference measurement resource, self-interference resource} resource pair. The network side device no longer needs to additionally configure the corresponding channel measurement resource when configuring the {interference measurement resource, self-interference resource} resource pair. The terminal can use the interference measurement result of the second resource and the channel measurement result of the third resource that has been obtained to calculate the CSI.

[0101] As another example, in addition to configuring the {interference measurement resource, self-interference resource} resource pair, the network side device also additionally configures a corresponding third resource. The terminal performs channel measurement and interference measurement on the third resource and the second resource in sequence. The terminal uses the channel measurement result of the third resource and the interference measurement result of the second resource to calculate the CSI.

[0102] The time domain where the second resource is located overlaps with the time domain where the first resource is located, including two situations: partial overlap and complete overlap.

[0103] Optionally, the time domain where the second resource is located is the same as the time domain where the first resource is located, or the time domain where the second resource is located is a subset of the time domain where the first resource is located.

[0104] That is, the time domain resources of the interference measurement resources are the same as the time domain resources of the self-interference resources, or the time domain resources of the interference measurement resources are a subset of the time domain resources of the self-interference resources. Here, the time domain resources refer to the time domain duration length of the resources.

[0105] Optionally, the first resource, the second resource, and the third resource satisfy at least one of the following:

[0106] The first resource and the second resource are a resource pair pre-configured by the network side device for self-interference measurement;

[0107] The first resource and the second resource are a resource pair dynamically indicated by the network side device for self-interference measurement;

[0108] The third resource is a resource pre-configured by the network side device for channel measurement;

[0109] The third resource is a resource dynamically indicated by the network side device for channel measurement;

[0110] The first resource and the second resource are a resource pair associated with the third resource and used for self-interference measurement;

[0111] The third resource is a resource for channel measurement that is closest to the resource pair in the time domain;

[0112] The third resource is a resource for channel measurement that is closest to the second resource in the time domain.

[0113] With respect to the configuration (or triggering or indicating) method of the first resource, the second resource, and the third resource, multiple embodiments are provided below:

[0114] Embodiment 1: The third resource and the resource pair are both configured in the first CSI report configuration.

[0115] In this embodiment, the network side device configures the channel measurement resource and the {interference measurement resource, self-interference resource} resource pair at the same time. In this solution, the UE performs channel measurement and interference measurement including SI at the same time based on the configured resources, and calculates the corresponding CSI (such as CQI).

[0116] For example, Figure 7 As shown, the network side device configures the channel measurement resource and the {interference measurement resource, self-interference resource} resource pair in the same CSI report configuration (CSI report config).

[0117] In the related art, the CSI report configuration is as follows:

[0118] CSI report configuration

[0119] {

[0120] NZP CSI-RS resource setting for channel measurement

[0121] CSI-RS resource for interference measurement(CSI-IM)

[0122] NZP CSI-RS resource setting for interference measurement

[0123] }

[0124] In the embodiment of the present application, the CSI report configuration is as follows:

[0125] CSI report configuration

[0126] {

[0127] NZP CSI-RS resource setting for channel measurement

[0128] CSI-RS resource for interference measurement(CSI-IM)

[0129] NZP CSI-RS resource setting for interference measurement

[0130] SI-resource setting for SI measurement

[0131] }

[0132] Compared with the CSI report configuration in the related art, the CSI report configuration in the embodiment of the present application adds an item "SI-resource setting for SI measurement", which indicates that SI resoruce is used as a self-interference generating resource (SIR). "SI-resource setting for SI measurement" can be associated with CMR or other IMR.

[0133] In this way, the network side device can configure "CSI report config" to the UE, the UE measures the CSI including SI, and reports it to the network, and the network side device can obtain the impact of UE self-interference on the channel state.

[0134] Optionally, the first CSI report configuration further includes:

[0135] A first parameter is used to characterize a report item related to cross-link interference.

[0136] Specifically, the network side device may include a cross link interference (CLI) item in the CSI report configuration, and may add a cross link interference item to the CSI report quantity to represent the interference measurement and reporting including the CLI. In the CSI report configuration, the CLI resoruce may be implicitly used as an IMR and associated with the CMR or other IMRs.

[0137] Embodiment 2: the third resource is configured in the second CSI reporting configuration, the resource pair is configured in the third CSI reporting configuration, and the second CSI reporting configuration is associated with the third CSI reporting configuration.

[0138] In this embodiment, the network side device only triggers the {interference measurement resource, self-interference resource} resource pair in a CSI report configuration, and the channel measurement resource may be a channel measurement resource in another CSI report configuration associated with the CSI report configuration. The associated CSI report configuration may be a CSI report configuration different from the CSI report configuration, or may be a CSI report configuration the same as the CSI report configuration.

[0139] Optionally, if the second CSI report configuration is configured with multiple resources for channel measurement, the third resource is a resource among the multiple resources that meets a preset condition.

[0140] Taking into account that the signal quality of the channel part of the UE is slowly changing, the resource that meets the preset condition may be the most recently available channel measurement resource. The preset condition may be the processing time. That is to say, for the channel measurement part of the CSI calculation, the channel measurement result obtained by the most recent channel measurement can be reused, and the UE can only measure the interference, that is, the UE only needs to update the measurement of the interference part. This is helpful to reduce the CSI-RS overhead and the processing time of the CSI calculation. In the case where only the {interference measurement resource, self-interference resource} resource pair is configured in the CSI report configuration, the UE only performs interference measurement including SI based on the configured resources, and calculates the corresponding CSI information.

[0141] Optionally, the third CSI report configuration further includes:

[0142] A first parameter is used to characterize a report item related to cross-link interference.

[0143] Embodiment 3: The network side device triggers only the channel measurement resource in a CSI report configuration, and the interference measurement result can be calculated based on the most recently available {interference measurement resource, self-interference resource} resource pair in another CSI report configuration associated with the CSI report configuration. The associated CSI report configuration can be a CSI report configuration different from the CSI report configuration, or a CSI report configuration the same as the CSI report configuration.

[0144] Embodiment 4: The third resource and the resource pair are both indicated (or triggered) by first downlink control information (Downlink Control Information, DCI).

[0145] In this embodiment, the network side device triggers the channel measurement resource and the {interference measurement resource, self-interference resource} resource pair simultaneously. In this solution, the UE performs channel measurement and interference measurement including SI based on the triggered resources at the same time, and calculates the corresponding CSI (such as CQI). For example, Figure 8 As shown, the network side device dynamically indicates (or triggers) a channel measurement resource and {interference measurement resource, self-interference resource} pair through the same DCI (ie, the first DCI).

[0146] Embodiment 5: The third resource is configured in a fourth CSI report configuration, and the resource pair is indicated (or triggered) by a second DC.

[0147] In this embodiment, the network side device indicates (or triggers) the {interference measurement resource, self-interference resource} resource pair through DCI, and configures the channel measurement resource through CSI report configuration.

[0148] For the case where the network side device only indicates (or triggers) the {interference measurement resource, self-interference resource} resource pair through DCI, the network side device can specify the associated CSI report configuration to determine the channel part or the interference part of the CSI.

[0149] For example, Fig. 9 As shown, when the DCI only indicates (or triggers) the {interference measurement resource, self-interference resource} resource pair in the CSI report configuration 1, the network side device can configure the channel measurement reference signal (Reference Signal, RS) of the associated CSI report configuration 2 for CSI calculation, for example, using the most recently available channel measurement RS of the CSI report configuration 2 for calculation.

[0150] For example, Fig.10As shown, the network side device can configure the periodic (or long-periodic) CSI report configuration 1, and then within a period, the DCI indicates (or triggers) non-periodic (or short-periodic) interference measurement, that is, the {interference measurement resource, self-interference resource} resource pair, whose channel measurement result is obtained by the nearest channel part, and then the CSI is calculated.

[0151] It should be noted that, for a CSI report configuration that triggers only interference measurement, the channel measurement part of the most recent CSI report configuration that it refers to may be of the same type or of a different type, that is, the channel part in the CSI report configuration that includes self-interference measurement, or the channel part of the CSI report configuration that does not include self-interference measurement (such as Fig.10 The channel portion of the t1 time in ).

[0152] Embodiment 6: The third resource is a periodic resource, and the first resource and the second resource are a periodic resource pair;

[0153] The period of the third resource is the same as or different from the period of the resource pair.

[0154] In this embodiment, the network side device may periodically configure a channel measurement resource and an {interference measurement resource, self-interference resource} resource pair. The channel measurement resource and the {interference measurement resource, self-interference resource} pair may have different periods or the same period. If the channel measurement resource and the {interference measurement resource, self-interference resource} pair have different periods, the terminal may determine the nearest channel measurement resource that meets the processing time requirement as the third resource. That is, for a CSI report, the UE may calculate the CSI (such as CQI) based on the nearest channel measurement resource and the {interference measurement resource, self-interference resource} pair that meets the processing time requirement.

[0155] Embodiment 7: The first resource is configured in a fifth CSI reporting configuration, and at least one of the second resource and the third resource is configured in a sixth CSI reporting configuration.

[0156] Optionally, the fifth CSI report configuration further includes at least one of the following:

[0157] A first parameter, wherein the first parameter is used to characterize a report item related to cross-link interference;

[0158] A second parameter, wherein the second parameter is used to characterize a report item related to self-interference.

[0159] Optionally, the second parameter includes a self-interference received signal strength indication SI-RSSI.

[0160] In this embodiment, a CSI report config may be configured to measure the impact of self-interference as follows:

[0161] CSI report configuration

[0162] {

[0163] SI-resource setting for SI measurement

[0164] }

[0165] The CSI report config may also include other options, as follows:

[0166] CSI report configuration

[0167] {

[0168] CSI-RS resource for interference measurement (CSI-IM) (optional)

[0169] NZP CSI-RS resource setting for interference measurement (optional)

[0170] SI-resource setting for SI measurement

[0171] }

[0172] A new CSI reportQuantity can be defined to characterize the quality of SI-related reports as follows:

[0173] The 'report Quantity' in the CSI report config contains

[0174] {

[0175] SI-RSSI

[0176] }

[0177] SI-RSSI stands for self-interference received signal strength indicator. The UE calculates the RSSI and reports it to the network side device, and the network side device can obtain the SI situation on the UE side.

[0178] It is also possible to explicitly add a cross link interference item in a new CSI reportQuantity to characterize the reporting quality related to cross links.

[0179] The above-mentioned embodiments 1 to 7 provide a variety of solutions for configuring (or triggering or indicating) the first resource, the second resource and the third resource. Through the above-mentioned embodiments, the first resource, the second resource and the third resource can be flexibly configured or indicated, which is conducive to supporting full-duplex transmission on the UE side.

[0180] The above-mentioned network side device configuration process and terminal self-interference measurement process of the embodiment of the present application can be applied in the self-interference measurement training process. The following provides a specific embodiment of the self-interference measurement training process.

[0181] Example 8: Self-interference measurement training process

[0182] In order to perform appropriate service scheduling for the terminal, the network side equipment needs to perform channel measurement on the terminal and obtain the terminal's self-interference suppression capability. One way to obtain the terminal's self-interference suppression capability is for the terminal to report the self-interference suppression capability. This requires the network side equipment to instruct the terminal to perform training including self-interference channel measurement, thereby obtaining the impact of self-interference on the channel state.

[0183] Specifically, the network side device can configure the UE to periodically send UL channels or signals in different frequency resources (or using different numbers of PRBs), using different powers and different spatial parameters. At the same time, the network side device can configure measurement resources for the UE to measure interference including self-interference (SI). The UE reports the measured channel state information to the network side device to assist the network side device in performing appropriate service scheduling.

[0184] For example, the self-interference measurement training method is as follows: the network side device configures or instructs the UE to periodically send L uplink channels or signals with bandwidth M, spatial parameter N and power parameter K, and the L uplink channels or signals span the UL subband bandwidth of the UE full-duplex operation.

[0185] The network side device may configure at least one CSI report config for the UE, and each CSI report config may be associated with an NZP CSI-RS resource, a CSI-IM resource, or an NZP CSI-RS interference measurement resource, and a transmitted UL channel or signal, that is, a channel or signal that generates self-interference. The network side device may configure the interference measurement resource to be time-domain aligned with the transmitted UL resource (channel or signal), that is, to send and receive simultaneously through the UE, measure the interference including SI through the interference measurement resource, and then report it to the network side device.

[0186] Optionally, the network-side device may configure a CSI-IM resource or NZP CSI-RS interference measurement resource without self-interference UL signal / channel transmission to measure interference without SI.

[0187] The UE obtains a CQI report and / or a subband CQI report according to the channel measurement resources and the interference measurement resources, and the network side device determines the interference including SI caused by the transmission on different transmission frequency resources based on the CQI report.

[0188] For example, the network side device configures the UE to periodically use spatial relation info a, power parameter b, and PRB number c to send SRS, and at the same time uses interference measurement resources such as (CSI-IM, NZP CSI-RS) based on the transmission configuration indicator (TCI) state d in the downlink for measurement. (The above a, b, c, d can represent at least one element in a parameter set. For the training process, each available element in the configuration parameter set needs to be rotated).

[0189] The network side device can configure multiple CSI report configs for the UE. The UE reports the measured CQI to the network according to the CSI report config. For example, a training process is as follows:

[0190] like Fig.11 As shown, the network side device instructs the UE to periodically send SRS at different frequencies and perform measurements at the same time.

[0191] At time t1, the UE measures CQI 1 according to CSI-RS1 and CSI-IM1, which can reflect the interference degree of SRS leakage at frequency A.

[0192] At time t2, the UE measures CQI 2 according to CSI-RS2 and CSI-IM2, which reflects the interference degree of SRS leakage at frequency B.

[0193] At time t3, the UE measures CQI 3 according to CSI-RS3 and CSI-IM3, which can reflect the interference degree of SRS leakage at frequency C.

[0194] At time t4, the UE measures CQI 4 according to CSI-RS4 and CSI-IM4, which can reflect the interference degree of SRS leakage at frequency D.

[0195] At time t5, the UE measures CQI 5 according to CSI-RS5 and CSI-IM5, which can reflect the channel condition without self-interference.

[0196] As shown in Table 1, different CQIs can characterize the self-interference strength of UL transmission on different frequencies. By reporting sub-band CQI by UE, the interference degree of SRS of one frequency resource to sub-bands of different DL frequency bands can be reflected. By reporting CQI1-CQI 4, the network can obtain the self-interference of UE at different UL transmission frequency positions.

[0197] Table 1

[0198]

[0199] It should be noted that when a terminal generates receiver blocking due to excessive signal transmission or channel power, the terminal may feedback out of range (out of range), that is, the CQI index is 0, to the network side device.

[0200] The network side device can determine the transmission parameters of UL and DL simultaneously sent and received by the UE based on the CQI with SI and the CQI without SI, such as UL transmission power, scheduled frequency resources, used spatial parameters, modulation and coding scheme (MCS) and other information. In other words, the network side device can realize appropriate service scheduling for the terminal, which is conducive to supporting full-duplex transmission on the UE side.

[0201] It should also be noted that the embodiment of the present application can not only be applied to the self-interference measurement training process shown in this embodiment, but in the subsequent communication process, the embodiment of the present application can also be used to implement regular or irregular self-interference measurement.

[0202] In summary, the embodiments of the present application can solve the configuration of UE full-duplex operation in NR, which is beneficial to improving system resource utilization, reducing latency, and improving coverage. The embodiments of the present application can be applied to systems such as LTE, CDMA, Global System for Mobile Communications (GSM), 5G and 6G.
