Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the protection scope of the present application.

It should be understood that the terms used in this manner may be substituted for each other where appropriate, so that the embodiments of this application may be practiced in other sequences than those shown or described herein, and that the objects distinguished by "first" and "second" generally belong to one category and do not limit the number of objects, for example, the first object may be one or more. In addition, in the specification and claims, "and / or" refers to at least one of the connected objects, and the symbol " / " generally refers to the relationship between the related objects of the preceding and following relationships being "or".

[0021] It should be noted that the technology described in the embodiments of the present application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used in other systems and wireless technologies in addition to the systems and wireless technologies mentioned above. Although the following description describes New Radio (NR) systems for illustrative purposes, and NR terminology is used in much of the following description, these techniques may be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0022] 1 shows 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. Here, the terminal 11 may be a mobile phone, a tablet personal computer, a laptop computer also called a notebook computer, a personal digital assistant (PDA), a personal digital assistant, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, a vehicle-mounted equipment (VUE), a pedestrian terminal (PUE), a smart home (a home device with a wireless communication function such as a refrigerator, a television, a washing machine, or furniture), a game machine, a personal computer (PC), an automated teller machine, a kiosk, or other terminal side device. The wearable device includes a smart watch, a smart wristband, a smart earphone, a smart glasses, a smart accessory (such as a smart bracelet, a smart ring, a smart necklace, a smart anklet, a smart wristlet, a smart wear, etc.) It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application. The network side equipment 12 may include an access network equipment or a core network equipment, where the access network equipment may be called a radio access network equipment, a radio access network (Radio Access Network, RAN), a radio access network function, or a radio access network unit.The access network equipment 12 may include a base station, a WLAN access point, or a WiFi node, etc., and the base station may be called a Node B, an evolved Node B (eNB), an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a Home B node, a Home evolved B node, a Transmitting Receiving Point (TRP), or any other suitable term in the art, and the base station is not limited to a specific technical term as long as the same technical effect can be achieved. It should be noted that the embodiments of this application only take a base station in an NR system as an example, but the specific type of the base station is not limited.

[0023] For example, many different types of wireless transceivers, such as LTE, 5G, WIFI, Bluetooth, GNSS, etc., may be equipped in the same terminal. Since the transceivers are in close proximity inside the terminal, the receiver of the terminal experiences interference from the transmitter of the terminal at adjacent or harmonic frequencies. Such interference may be from the same or different Radio Access Technologies (RATs).

[0024] When an IDC problem occurs in a terminal, the terminal can report 3GPP (registered trademark) frequency points affected by IDC to a network side device. The network side device can solve the IDC problem by deleting the affected frequency points (e.g., switching to a different frequency point or deleting a serving cell corresponding to a frequency band) based on the frequency point information reported by the terminal. However, if the network side deletes the entire frequency point, it will reduce the frequency domain resources available to the terminal, lowering the resource utilization rate.

[0025] Therefore, the network side needs finer granularity of interference assistance information to avoid dealing with the IDC problem by deleting entire frequency points and further increase the frequency domain resources available to the UE.

[0026] In a 5G system, a terminal may only support one small operating bandwidth (e.g., 5 MHz), but one cell on the network side may support a large bandwidth (e.g., 100 MHz), and the small bandwidth portion of the large bandwidth in which the terminal operates is considered to be the bandwidth part (BWP).

[0027] The network side device can configure one or more BWPs in the terminal, and switch the BWPs that the terminal can operate on by activating or deactivating the BWPs.

[0028] It is common for the network side equipment to configure a default BWP, and when the terminal operates in another BWP in the cell, the network side equipment can configure a timer in the terminal that operates in the other BWP in the cell, and when the timer expires, the terminal switches back to the default BWP.

[0029] Next, a method for reporting interference assistance information provided in an embodiment of the present application will be described in detail with reference to the drawings according to several embodiments and use cases thereof.

[0030] FIG. 2 is a schematic diagram 1 of an interaction flow of an embodiment of a method for reporting interference support information provided in an embodiment of the present invention. As shown in FIG. 2, the method provided in this embodiment includes: The method includes step 101 in which, when an IDC problem occurs, the terminal notifies a network side device of interference support information including at least one of interference support information at a bandwidth portion BWP level and interference support information at a physical resource block PRB level.

[0031] Specifically, when an IDC problem occurs due to interference from a transmitter to a receiver of a terminal, the terminal reports interference support information to a network side to support the network in handling the IDC problem. Or, when an IDC problem occurs due to interference from a transmitter of the terminal to a receiver of the terminal, the terminal reports interference support information to a network side to support the network in handling the IDC problem. Therefore, the interference support information reported by the terminal plays an important role in solving the IDC problem.

[0032] It should be noted that if an IDC problem occurs and the terminal is unable to resolve it by itself, it may report interference support information to the network side.

[0033] The interference support information reported by the terminal includes at least one of interference support information at a bandwidth portion BWP level and interference support information at a physical resource block PRB level, where after the terminal reports the interference support information at a BWP level and / or a PRB level, the network side can determine the BWP and / or PRB that has caused interference, or the BWP or PRB that has been interfered with, according to the interference support information at the BWP level and / or the PRB level, and further handle the IDC problem.

[0034] For example, when an IDC problem occurs in terminal A, terminal A reports interference support information to the network side, which includes information indicating that interference exists in BWP1. Based on the interference support information, the network side can instruct terminal A to stop transmitting and receiving data in BWP1 or to switch to another BWP and communicate using resources of another BWP that is not subject to interference.

[0035] According to the method of the above embodiment, when an IDC problem occurs, the terminal reports interference support information to the network side to assist the network in handling the IDC problem, where the interference support information reported by the terminal is at the BWP level and / or PRB level, i.e., the interference support information reported by the terminal is detailed up to the BWP and / or PRB, thereby enabling the network side to handle the IDC problem using finer-grained interference support information, and improving resource utilization.

[0036] Optionally, the BWP-level interference support information is used to inform the network side device of unavailable BWP information, or is used to inform the network side device of BWP information affected by IDC, or the BWP-level interference support information is used to inform the network side device of available BWP information, where the BWP-level interference support information is: The information may be one or more of BWP identification information, cell identification information, frequency identification information, bandwidth information, frequency domain starting position information, a BWP bitmap, and location index information of candidate BWP information.

[0037] It should be noted that the BWP level interference support information reported by the terminal may be one or more BWP information words. Here, each BWP information word may correspond to one or more BWP resources. The BWP resource corresponding to each BWP information word may be represented by a BWP identifier, a cell identification information and a BWP identification information, a frequency domain start position information and a bandwidth information, a frequency identification information and a bandwidth information identifier, etc. Optionally, each BWP information word may correspond to a specific frequency point, a specific frequency band, a specific cell group, a specific frequency band combination, a specific cell, etc.

[0038] Alternatively, the following examples may be specific examples of the above BWP information words:

[0039] For example, the BWP-level interference support information may include a cell ID and a BWP ID and indicate that the bandwidth portion BWP corresponding to the BWP ID and arranged in the cell corresponding to the cell ID is an unavailable BWP resource. It should be noted that the unavailable BWP resource may be a frequency domain resource that is evaluated and determined by the terminal itself and is unavailable for uplink or downlink data transmission. Alternatively, the BWP-level interference support information may include a cell ID and a BWP ID and transmit the bandwidth portion BWP corresponding to the BWP ID and arranged in the cell corresponding to the cell ID is a BWP resource affected by the IDC. In such a case, the terminal may further indicate whether the bandwidth portion BWP is an interfering side or an interfered side. Specifically, the BWP-level interference support information may be a BWP list={BWP1, BWP2, BWP3}. In such a case, it may be indicated that all frequency domain resources corresponding to BWP ID=1, 2, 3 in all serving cells are unavailable BWP resources. Alternatively, the BWP-level interference support information may be a cell list={cell 1, cell 2, cell 3}. In this case, it may be indicated that all BWPs configured in the serving cells corresponding to cell IDs = 1, 2, and 3 are unavailable BWP resources. Or, the BWP-level interference support information may be a BWP list = {BWP1 (cell 1, cell 2), BWP2 (cell 2, cell 3)}. In this case, it may be indicated that the frequency domain resources of BWP ID = 1 configured in the serving cells corresponding to cell IDs = 1 and 2 and the frequency domain resources of BWP ID = 2 configured in the serving cells corresponding to cell IDs = 2 and 3 are all unavailable BWP resources. Or, the BWP-level interference support information may be a cell list = {cell 1 (BWP1, BWP2), cell 2 (BWP2, BWP3)}.In this case, it may be indicated that the frequency domain resources of BWP IDs = 1 and 2 configured in the serving cell corresponding to cell ID = 1 and the frequency domain resources of BWP IDs = 2 and 3 configured in the serving cell corresponding to cell ID = 2 are all unavailable BWP resources. Other combination examples will not be listed one by one.

[0040] As another example, frequency identification information ARFCN and bandwidth information W may be included in the BWP level interference support information and transmitted to indicate that the frequency domain resources corresponding to (ARFCN-compatible frequency, ARFCN-compatible frequency+W), or (ARFCN-compatible frequency-W / 2, ARFCN-compatible frequency+W / 2), or (ARFCN-compatible frequency-W, ARFCN-compatible frequency) are unavailable resources.

[0041] As another example, the BWP level interference support information may be transmitted including frequency domain start position information and bandwidth information W, indicating that the frequency domain resource corresponding to (frequency corresponding to the frequency domain start position information f, f+W), or (fW / 2, f+W / 2), or (fW, f) is an unavailable resource.

[0042] As another example, a BWP bitmap may be included in the BWP-level interference support information and transmitted. The bit positions of the BWP bitmap correspond to a specific BWP. In one scenario, the bitmap may be designed to map the bit positions in the bitmap one by one in ascending order of cell IDs and ascending order of BWP IDs corresponding to the same cell ID. For example, serving cells cell 1 and cell 2 are configured in a terminal, among which BWP1 and BWP2 are configured correspondingly in cell 1, and BWP1 is configured correspondingly in cell 2. Thus, the length of the BWP bitmap is 3 (i.e., equal to the total number of BWPs configured in the terminal), the first bit position of the bitmap corresponds to BWP1 configured in cell 1, the second bit position of the bitmap corresponds to BWP2 configured in cell 1, and the third bit position of the bitmap corresponds to BWP1 configured in cell 2. In another scenario, the bitmap may be designed to map the bit positions in the bitmap one by one in the arrangement order of candidate BWPs. For example, a network side device provides candidate BWP information for detecting an IDC problem to a terminal, and the BWP information transmitted in the information includes BWP1 of cell 1 and BWP1 of cell 2, and thus the length of the BWP bitmap is 2 (i.e., equal to the total number of candidate BWPs arranged in the terminal), the first bit position of the bitmap corresponds to BWP1 arranged in cell 1, and the second bit position of the bitmap corresponds to BWP1 arranged in cell 2. In the above bitmap design, the specific value of the bit position may be used to notify the network side whether the BWP corresponding to the bit position is an unavailable BWP or an IDC-affected BWP. For example, the protocol may specify that when the bit position value is "1", the network side device is notified that the BWP corresponding to the bit position is an unavailable BWP. Or, the protocol may specify that when the bit position value is "1", the network side device is notified that the BWP corresponding to the bit position is affected by IDC.Alternatively, the terminal may further include another information for indicating whether the BWP is an interference side or an interfered side when transmitting. For example, the terminal further includes and transmits another interference direction bitmap, the length of the bitmap is equal to the length of the BWP bitmap, and the bit position of the bitmap is used to indicate whether the BWP corresponding to the bit position is an interference side or an interfered side. For example, in the BWP bitmap {1,0,1}, the first bit corresponds to BWP1 of cell 1, the second bit corresponds to BWP2 of one cell 1, and the third bit corresponds to BWP1 of cell 2. A value of 1 in a bit position indicates that the corresponding BWP is a BWP affected by IDC. The interference direction bitmap sent separately by the UE is {1,0,0}, where the first bit corresponds to BWP1 of cell 1 and has a value of 1, indicating that the BWP is the interfering side, the second bit corresponds to BWP2 of one of cell 1 and the BWP bitmap indicates that the BWP is not a BWP affected by IDC, so the network side device may ignore the bit position corresponding to the BWP in the interference direction bitmap, and the third bit corresponds to BWP1 of cell 2 and has a value of 0, indicating that the BWP is the interfered side.

[0043] As another example, the BWP-level interference assistance information may be transmitted including the location index information of the candidate BWP. For example, a network side device provides the terminal with candidate BWP information for detecting an IDC problem, and the BWP information transmitted including the information includes BWP1 of cell 1 and BWP1 of cell 2. The terminal associates the candidate BWPs with the location indexes according to a specified rule. The specified rule may be based on the order of provision or location of the candidate BWPs. In the above example, the terminal may associate BWP1 of cell 1 with location index 1 and BWP1 of cell 2 with location index 2. The terminal notifies whether the BWP corresponding to the location index is a BWP affected by IDC by broadcasting the location index of the BWP.

[0044] Optionally, the PRB-level interference support information is used to inform the network side device of unavailable PRB information, or is used to inform the network side device of IDC-affected PRB information, or the PRB-level interference support information is used to inform the network side device of available PRB information, where the PRB-level interference support information may include one or more of the following: PRB start position information, where the PRB start position information may be represented by a PRB ID or a PRB index. PRB end position information, where the PRB end position information may be represented by a PRB ID or a PRB index. PRB quantity information. Bandwidth information. Optionally, the bandwidth information may be used to determine the number of PRBs. For example, the network side can determine a sub-carrier space (SCS) based on the BWP where the PRB resource is located, and then convert the bandwidth indicated by the bandwidth information into the number of PRBs. PRB bitmap. The location index of the candidate PRB information.

[0045] The PRB level interference assistance information further includes one or more of the following: BWP identification information, where the BWP identifier indicates the bandwidth portion BWP to which the frequency domain resource corresponding to the PRB information belongs, and is used to notify the network side device of the unavailable PRB resource, the PRB resource affected by the IDC, or the available PRB resource in the bandwidth portion corresponding to the BWP ID. Cell identification information, where the cell identifier indicates the cell to which the frequency domain resource corresponding to the PRB information belongs, and is used to notify the network side device of the unavailable PRB resource, the PRB resource affected by the IDC, or the available PRB resource in the frequency domain resource corresponding to the cell ID. Frequency band identification information, where the frequency band identification information indicates a frequency band to which the frequency domain resource corresponding to the PRB information belongs, and is used to notify a network side device of unavailable PRB resources, PRB resources affected by IDC, or available PRB resources in the frequency domain resource corresponding to the frequency band identifier.

[0046] It should be noted that the PRB-level interference support information reported by the terminal may be one or more PRB information words. Here, each PRB information word may indicate one PRB or multiple PRBs, such as multiple consecutive PRBs. The PRB resource corresponding to each PRB information word may be represented by PRB origin location information, PRB ID, or PRB index. In this case, the PRB information word corresponds to one PRB resource. Each PRB information word may further be represented by PRB origin location information and PRB end location information, PRB start location information and PRB quantity information, PRB origin location information and bandwidth information, PRB end location information and PRB quantity information, PRB end location information and bandwidth information, etc. In this case, the PRB information word corresponds to multiple PRB resources. For example, it corresponds to multiple consecutive PRBs.

[0047] Optionally, each PRB information word may correspond to a particular frequency point, a particular frequency band, a particular cell group, a particular frequency band combination, a particular cell, etc.

[0048] Alternatively, the following example may be a specific example of the above PRB information word:

[0049] As an example, the PRB level interference support information may be PRB origin location information and PRB end location information, in which case it indicates that all frequency domain resources from the PRB corresponding to the PRB origin location information to the PRB corresponding to the PRB end location information are unavailable PRB resources. Or, the PRB level interference support information may be PRB origin location information and PRB quantity information (e.g., N), in which case it indicates that N consecutive PRBs from the PRB corresponding to the PRB origin location information are unavailable PRB resources. Or, the PRB information may be PRB end location information and PRB quantity information (e.g., N), in which case it indicates that N consecutive PRBs from the PRB corresponding to the PRB end location information forward are candidate PRB resources for IDC problem detection.

[0050] As another example, the PRB level interference support information may be the allocation index information of the candidate PRB resource. For example, the network side device provides the terminal with candidate PRB information for detecting an IDC problem. The candidate PRB information may include multiple PRB information words and be transmitted, with each PRB information word corresponding to a specific PRB or multiple specific PRBs. The terminal needs to detect whether an IDC problem occurs in the PRB resource corresponding to each PRB information word. When an IDC problem occurs, the terminal notifies the network side device of the allocation index corresponding to the PRB resource. Specifically, the terminal associates the candidate PRB resource with the allocation index according to a specified rule. The specified rule may be based on the order of providing or the order of arrangement of the candidate PRBs. In the above example, the terminal may associate the PRB resource corresponding to each PRB information word with the allocation index. For example, the first PRB information word transmitted in the PRB information for detecting an IDC problem is associated with the allocation index 1, and the second PRB information word is associated with the allocation index 2, and so on.

[0051] As another example, the PRB-level interference support information may be a PRB bitmap. For example, a bit position of the PRB bitmap corresponds to a specific candidate PRB resource. In one scenario, the bitmap may be designed to map the candidate PRB resources to the bit positions in the bitmap one by one in the arrangement order. For example, the network side device provides the terminal with candidate PRB information for detecting an IDC problem. The candidate PRB information may include and transmit a plurality of PRB information words, each of which corresponds to a specific PRB or a plurality of specific PRBs. The terminal needs to detect whether an IDC problem occurs in the PRB resource corresponding to each PRB information word. In the above example, the bit position of the PRB bitmap corresponds to the PRB information word. For example, the protocol may specify that when the value of the bit position is "1", the network side device is notified that the PRB corresponding to the bit position is an unavailable PRB. Or, the protocol may specify that when the value of the bit position is "1", the network side device is notified that the PRB corresponding to the bit position is affected by IDC. In another scenario, the bitmap may be designed to map one by one to the bit positions in the bitmap in the order of PRB ID or PRB index. In this example, one bit position corresponds to a PRB resource of a specific PRB ID or PRB index. When the bit position is set to a specific value, it indicates that the PRB resource corresponding to the bit position is an unavailable PRB resource, or indicates that the PRB resource corresponding to the bit position is an IDC-affected PRB resource, or indicates that the PRB resource corresponding to the bit position is an available PRB resource. The protocol may specify the corresponding specific meaning when the bit position is set to a specific value.

[0052] In one embodiment, a method for reporting interference support information includes: The method further includes a step of the terminal obtaining broadcast configuration information of the interference support information.

[0053] The terminal selectively broadcasts the interference-supporting information to a network side device based on broadcast configuration information of the interference-supporting information. Here, the notification arrangement information is On / off control information for reporting interference support information; Granularity arrangement information for reporting interference support information; The target candidate resource information includes at least one item of target candidate resource information.

[0054] Specifically, the terminal determines how to report interference-supporting information according to the acquired reporting configuration information. The reporting configuration information includes at least one of the following: on-off control information of reporting interference-supporting information, granularity configuration information of reporting interference-supporting information, and target candidate resource information. That is, the terminal needs to report BWP level and / or PRB level interference-supporting information according to the acquired on-off control information of reporting interference-supporting information, and / or granularity configuration information of reporting interference-supporting information, and / or target candidate resource information, thereby reporting finer granularity interference-supporting information to help network side equipment solve IDC problem and achieve the purpose of improving resource utilization rate.

[0055] Selectively, the reporting configuration information may include explicit on / off control information or implicit on / off control information. For example, the reporting configuration information includes an explicit instruction field, and the information indicated in the instruction field is on / off control information. Alternatively, the reporting configuration information includes granular configuration information and / or target candidate resource information. In this case, the granular configuration information and / or target candidate resource information can implicitly indicate the on / off control information. For example, when the reporting configuration information includes granular configuration information, the terminal is instructed to turn on the reporting of BWP level and / or PRB level interference support information.

[0056] In the above embodiment, the terminal obtains reporting configuration information of interference support information, where the reporting configuration information includes at least one of on / off control information for reporting interference support information, granularity configuration information for reporting interference support information, and target candidate resource information, and the terminal reports interference support information based on the reporting configuration information, reports interference support information at a BWP level and / or a PRB level, thereby realizing reporting of interference support information with finer granularity.

[0057] In one embodiment, the on / off control information is Whether the terminal turns on or off reporting of BWP level and / or PRB level interference support information; The terminal is used to indicate at least one of information on whether to turn on or not to report BWP level and / or PRB level interference support information for a target candidate resource.

[0058] Specifically, the on / off control information in the reporting configuration information can instruct the terminal whether to turn on or off reporting of BWP level and / or PRB level interference supporting information, and / or whether to turn on or off reporting of BWP level and / or PRB level interference supporting information for the target candidate resource.

[0059] When the on / off control information is included in the above-mentioned reporting configuration information and transmitted, and the on / off control information included in the above-mentioned reporting configuration information is set to a specific value, the terminal is considered to be configured to allow reporting of interference support information, and when the on / off control information is included in the reporting configuration information and transmitted, and the on / off control information included in the reporting configuration information is set to a specific value, the terminal can selectively turn on reporting of BWP level and / or PRB level interference support information, or turn on reporting of BWP level and / or PRB level interference support information for a target candidate resource, that is, the terminal can obtain the on / off control information in the reporting configuration information to determine what level of interference support information to turn on, or to determine what level of interference support information to turn on for which resource, thereby realizing reporting of interference support information with finer granularity.

[0060] In the above embodiment, the on-off control information is used to instruct the terminal to turn on reporting of interference support information at the bandwidth portion BWP level and / or the physical resource block PRB level, or the on-off control information is used to instruct the terminal to turn on reporting of interference support information at the BWP level and / or the PRB level in a resource corresponding to the target candidate resource information, that is, the terminal can determine what level of interference support information to turn on by obtaining the on-off control information in the reporting configuration information, or determine what level of interference support information to turn on in which resource, thereby realizing reporting of interference support information with finer granularity.

[0061] It needs to be explained that the on-off control information may be explicit on-off control information or implicit on-off control information.

[0062] As an example of explicit on / off control information, the format of the on / off control information is: The first length indication field, It is one of the first bitmaps.

[0063] Specifically, the on / off control information to be included in the broadcast configuration information and transmitted may be an instruction field of a first length, and the value of the instruction field can instruct the terminal to turn on or off the broadcast of the interference supporting information at the BWP level and / or the PRB level. In this case, the on / off control information corresponds to the on / off control instruction information per UE. Or, the terminal can be instructed to turn on or off the broadcast of the interference supporting information at the BWP level and / or the PRB level for the target candidate resource. In this case, the on / off control information corresponds to the on / off control information per resource (for example, per frequency or per BWP or per PRB).

[0064] For example, the value of the indication field of the on / off control information is represented by the bit position of the first length, for example, a 1-bit indication field idc-indication-r18 of the on / off control information is introduced, and when the indication field idc-indication-r18 of the on / off control information is set to true, the terminal is configured to allow reporting of BWP level and / or PRB level interference support information. In this example, the terminal is considered to turn on reporting of per BWP and / or per PRB level interference support information for all configured candidate resources (e.g., candidate frequency resources for IDC problem detection). An exemplary signaling configuration is as follows: JPEG2025503596000002.jpg63141 Here, the Idc-Indication-r18 field is used to indicate whether the terminal is configured to turn on transmission of IDC interference support information (InDeviceCoexindication) to the network side at the PRB level / BWP level.

[0065] The on / off control information may further be represented by a first bitmap, and a bit position of the first bitmap is used to indicate whether to turn on or not to turn on the reporting of BWP level and / or PRB level interference supporting information for the target candidate resource. In the signaling configuration as described below, the reporting configuration information of the interference supporting information includes a candidate frequency list for detecting an IDC problem and bitmap information for indicating whether to turn on or not to turn on the reporting of BWP level and / or PRB level interference supporting information for the resource corresponding to the candidate frequency list, and is transmitted. The n-th bit position in the first bitmap corresponds to the n-th frequency in the candidate frequency list, and indicates that the frequency resource supports the reporting of BWP and / or PRB level interference supporting information when the bit position is set to a specific value.

[0066] An exemplary signaling arrangement is as follows: JPEG2025503596000003.jpg78141

[0067] It should be noted that the above specific value may be configured by the network side device or may be predefined in the protocol.

[0068] Optionally, when the granularity configuration information of the reporting of interference support information and / or the target candidate resource information for IDC problem detection are included in the reporting configuration information and transmitted, the terminal is considered to be configured to be permitted to report interference support information, where the target candidate resource information for IDC problem detection may be a newly introduced information field. Furthermore, the terminal is considered to be configured to be permitted to report finer granularity interference support information, for example, the terminal is considered to be configured to be permitted to report BWP level and / or PRB level interference support information. For example, when the candidate BWP information for IDC problem detection is included in the reporting configuration information and transmitted, the terminal is considered to be configured to be permitted to report BWP level interference support information. When the candidate PRB information for IDC problem detection is included in the reporting configuration information and transmitted, the terminal is considered to be configured to be permitted to report PRB level interference support information.

[0069] As an example of implicit on / off control information, the reporting configuration information of the interference support information includes target candidate resource information (e.g., a candidate frequency list) for IDC problem detection and transmits the target candidate resource information, which may be a newly introduced information field and is used to instruct the frequency resources included in the candidate frequency list to turn on the reporting of BWP level / PRB level interference support information. Optionally, in the signaling configuration as described below, compared with the conventional mechanism, the reporting configuration information of the interference support information includes a new candidate frequency list CandidateServingFreqListNR-r18 for IDC problem detection and transmits it. In this case, the terminal considers that it has turned on the reporting of BWP level or PRB level interference support information for the frequency resources included in CandidateServingFreqListNR-r18, but has not turned on the reporting of BWP level or PRB level interference support information for the frequency resources included in CandidateServingFreqListNR-r16.

[0070] As an example, the signaling arrangement is as follows: JPEG2025503596000004.jpg81164 Here, the granularity arrangement information of the reporting of the interference support information is A first indication field for reporting interference support information of BWP level; It may be one or more of the second indication fields reporting PRB level interference support information.

[0071] Optionally, the first instruction field is Whether the terminal turns on the reporting of BWP level interference support information or not, Used for indicating at least one of information on whether the terminal turns on or does not turn on reporting of BWP level interference support information for the target candidate resource; The second instruction field is Whether the terminal turns on PRB-level interference support information reporting or not; The parameter is used to indicate at least one of information on whether the terminal turns on or off reporting of PRB-level interference support information for the target candidate resource.

[0072] Specifically, when the first instruction field is included in the above-mentioned reporting configuration information and transmitted, and the first instruction field included in the above-mentioned reporting configuration information and transmitted is set to a specific value, the terminal is considered to be configured so as to be permitted to report BWP-level interference supporting information or to turn on reporting of BWP-level interference supporting information for a target candidate resource.

[0073] When the second instruction field is included in the above reporting configuration information and transmitted, and the second instruction field included in the above reporting configuration information and transmitted is set to a specific value, the terminal is considered to be configured to be permitted to report PRB level interference support information or to turn on reporting of PRB level interference support information for a target candidate resource.

[0074] Optionally, the format of the first instruction field is A second length indication field, It is one of the second bitmaps.

[0075] Optionally, the format of the second instruction field is A third length indication field, It is one of the third bitmaps.

[0076] As an example, the granularity arrangement information is included in the reporting arrangement information of the interference-supporting information and transmitted. Here, when the first instruction field for reporting the interference-supporting information at the BWP level and the second instruction field for reporting the interference-supporting information at the PRB level are both 1-bit instruction fields with a value of 0, it means that the reporting of the interference-supporting information at the BWP level and the interference-supporting information at the PRB level are not turned on. Or, when the first instruction field and the second instruction field are both 1-bit instruction fields with a value of 1, it means that the reporting of the interference-supporting information at the BWP level and the interference-supporting information at the PRB level are turned on. Or, when the first instruction field and the second instruction field are 1-bit instruction fields with values ​​of 0 and 1, respectively, it means that the reporting of the interference-supporting information at the BWP level is not turned on, but the reporting of the interference-supporting information at the PRB level is turned on. When the first instruction field and the second instruction field are 1-bit instruction fields with values ​​of 1 and 0, respectively, it means that the reporting of the interference-supporting information at the BWP level is turned on, but the reporting of the interference-supporting information at the PRB level is not turned on. In the signaling arrangement as described below, when the reporting arrangement information is transmitted including a candidate frequency list for detecting an IDC problem and a first instruction field for reporting BWP-level interference supporting information, the terminal is considered to turn on reporting of BWP-level interference supporting information for all frequencies included in CandidateServingFreqListNR-r16.

[0077] As an example, the signaling arrangement is as follows: JPEG2025503596000005.jpg76146

[0078] As another example, the first indication field reporting the interference supporting information at the BWP level and the second indication field reporting the interference supporting information at the PRB level are both bitmaps.

[0079] Specifically, the bit position of the second bitmap is used to indicate whether to turn on or not to turn on the reporting of BWP-level interference supporting information for the target candidate resource. In the signaling arrangement as described below, the reporting arrangement information of the interference supporting information includes a candidate frequency list for detecting an IDC problem and bitmap information for indicating whether to turn on or not to turn on the reporting of BWP-level interference supporting information for the resource corresponding to the candidate frequency list, and is transmitted. The n-th bit position in the second bitmap corresponds to the n-th frequency in the candidate frequency list, and indicates that the frequency resource supports the reporting of BWP-level interference supporting information when the bit position is set to a specific value.

[0080] The bit position of the third bitmap is used to indicate whether to turn on or not to turn on the reporting of the PRB-level interference supporting information for the target candidate resource. In the signaling configuration as described below, the reporting configuration information of the interference supporting information includes a candidate frequency list for detecting an IDC problem and bitmap information for indicating whether to turn on or not to turn on the reporting of the PRB-level interference supporting information for the resource corresponding to the candidate frequency list, and is transmitted. The n-th bit position in the third bitmap corresponds to the n-th frequency in the candidate frequency list, and indicates that the frequency resource supports the reporting of the PRB-level interference supporting information when the bit position is set to a specific value.

[0081] As an example, the signaling arrangement is as follows: JPEG2025503596000006.jpg88125 Here, the target candidate resource information for IDC problem detection may be one or more of the following:

[0082] The target candidate resource information is Candidate frequency information, Candidate BWP information, It includes at least one item of candidate PRB information.

[0083] Optionally, the candidate BWP information includes: The information includes at least one of BWP identification information, cell identification information, frequency identification information, bandwidth information, frequency domain starting point position information, BWP bitmap, and frequency band identification information.

[0084] As an example, the signaling arrangement is as follows: JPEG2025503596000007.jpg114164

[0085] Optionally, the candidate PRB information includes at least one of PRB starting point location information, PRB ending point location information, PRB quantity information, bandwidth information, and a PRB bitmap.

[0086] Optionally, the candidate PRB information comprises: The information further includes at least one of frequency point information, BWP information, cell information, and frequency band information.

[0087] Specifically, for example, the candidate frequency information for detecting an IDC problem may be a candidate frequency list arranged by a network side device, and the terminal also reports interference support information when any frequency in the candidate frequency list is affected by IDC. The difference from the candidate frequency arrangement by the network in the conventional mechanism is that the candidate frequency information may be a newly introduced information domain. When the network side device provides the candidate frequency information, the terminal can report interference support information at the BWP level and / or PRB level even when any candidate frequency is affected by IDC.

[0088] For example, the candidate BWP information for detecting an IDC problem may be a BWP information list arranged by a network side device, and the terminal also broadcasts interference support information when a frequency domain corresponding to any BWP information in the BWP information list is affected by resource IDC. Here, the candidate BWP information is: The BWP bitmap includes at least one of BWP identification information, cell identification information, frequency identification information, bandwidth information, frequency domain starting position information, BWP bitmap, and frequency band identification information. Wherein, a bit position of the BWP bitmap corresponds to a specific BWP. Specifically, the bit positions of the BWP bitmap may be mapped one by one in ascending order of cell IDs and ascending order of BWP IDs corresponding to the same cell ID.

[0089] It should be noted that the candidate BWP information for detecting an IDC problem configured by the network side may include one or more BWP information words, where each BWP information word may correspond to one or more BWP resources. The BWP resource corresponding to each BWP information word may be represented by a BWP identifier, a cell identification information and a BWP identification information, a frequency domain starting position information and a bandwidth information, a frequency identification information and a bandwidth information identifier, etc.

[0090] Optionally, each BWP information word may correspond to a particular frequency point, a particular frequency band, a particular cell group, a particular frequency band combination, a particular cell, and so on.

[0091] Alternatively, the following examples may be specific examples of each of the above BWP information words:

[0092] For example, the candidate BWP information may be BWP list={BWP1, BWP2, BWP3}, in which case the terminal considers that all frequency domain resources corresponding to BWP ID=1, 2, 3 in all serving cells are candidate resources for IDC problem detection. Or, the candidate BWP information may be cell list={cell 1, cell 2, cell 3}, in which case the terminal considers that all BWPs configured in serving cells corresponding to cell ID=1, 2, 3 are candidate BWP resources for IDC problem detection. Or, the candidate BWP information may be BWP list={BWP1(cell 1, cell 2), BWP2(cell 2, cell 3)}, in which case the terminal considers that all frequency domain resources of BWP ID=1 configured in serving cells corresponding to cell ID=1, 2 and frequency domain resources of BWP ID=2 configured in serving cells corresponding to cell ID=2, 3 are candidate BWP resources for IDC problem detection. Alternatively, the candidate BWP information may be cell list={cell 1 (BWP1, BWP2), cell 2 (BWP2, BWP3)}, in which case the UE considers that the frequency domain resources of BWP IDs=1 and 2 configured in the serving cell corresponding to cell ID=1 and the frequency domain resources of BWP IDs=2 and 3 configured in the serving cell corresponding to cell ID=2 are all candidate BWP resources for detecting an IDC problem. Other combination examples will not be given one by one.

[0093] As another example, the candidate BWP information may be BWP list={(BWP1, BWP2)}, where BWP1 is represented by frequency domain start position information and bandwidth information. In this case, the terminal considers that the frequency domain resource corresponding to (frequency point corresponding to frequency domain start position information, frequency point corresponding to frequency domain start position information+bandwidth) is the candidate BWP resource for IDC problem detection. Or, BWP1 is represented by frequency identifier and bandwidth information, for example, frequency identifier parameter ARFCN and bandwidth information W. In this case, the terminal considers that the frequency domain resource corresponding to (ARFCN corresponding frequency, ARFCN corresponding frequency+W), or (ARFCN corresponding frequency-W / 2, ARFCN corresponding frequency+W / 2), or (ARFCN corresponding frequency-W, ARFCN corresponding frequency) is the candidate BWP resource for IDC problem detection. Other combination examples will not be listed one by one.

[0094] As another example, the candidate BWP information may be a BWP bitmap. A bit position of the BWP bitmap corresponds to a specific BWP. The bitmap may be designed to map the bit positions in the bitmap one by one in ascending order of cell IDs and ascending order of BWP IDs corresponding to the same cell ID. For example, a serving cell cell 1 and cell 2 are configured in a terminal, among which BWP1 and BWP2 are configured correspondingly in cell 1, and BWP1 is configured correspondingly in cell 2. Thus, the length of the BWP bitmap is 3 (i.e., equal to the total number of BWPs configured in the terminal), the first bit position of the bitmap corresponds to BWP1 configured in cell 1, the second bit position of the bitmap corresponds to BWP2 configured in cell 1, and the third bit position of the bitmap corresponds to BWP1 configured in cell 2. In the above bitmap design, the specific value of the bit position may be used to inform the terminal whether the BWP corresponding to the bit position is a candidate BWP resource for IDC problem detection. For example, the protocol may specify that when the value of a bit position is "1", the terminal is notified that the BWP corresponding to the bit position is a candidate BWP resource for IDC problem detection. Or, the protocol may specify that when the value of a bit position is "0", the terminal is notified that the BWP corresponding to the bit position is not a candidate BWP resource for IDC problem detection. As an example, the BWP bitmap is {1,0,1}, where the first bit position corresponds to BWP1 of cell 1, the second bit position corresponds to BWP2 of one cell 1, and the third bit position corresponds to BWP1 of cell 2. The value of a bit position is 1, which means that the corresponding BWP is a candidate BWP resource for IDC problem detection, i.e., BWP1 of cell 1 and BWP1 of cell 2 are candidate BWP resources for IDC problem detection, but BWP2 of cell 1 is not a candidate BWP resource for IDC problem detection.

[0095] Optionally, the candidate PRB information for detecting an IDC problem may be a PRB information list configured by a network side device, and the terminal also reports interference support information when a frequency domain resource corresponding to any PRB information in the PRB information list is affected by IDC. Here, the candidate PRB information may be one or more of the following: PRB start position information, where the PRB start position information may be represented by a PRB ID or a PRB index. PRB end position information, where the PRB end position information may be represented by a PRB ID or a PRB index. PRB quantity information. Bandwidth information. Optionally, the bandwidth information may be used to determine the number of PRBs. For example, the UE can determine the SCS based on the BWP where the PRB resource is located, and then convert the bandwidth indicated in the bandwidth information into the number of PRBs. Or convert the bandwidth information into the number of PRBs based on the reference SCS. PRB bitmap.

[0096] It should be noted that the candidate PRB information for detecting an IDC problem configured by the network side may include one or more PRB information words. Here, each PRB information word may indicate a PRB or multiple PRBs, such as multiple consecutive PRBs. The PRB resource corresponding to each PRB information word may be represented by PRB origin location information, PRB ID, PRB index, PRB bitmap, etc. In this case, the PRB information word corresponds to one PRB resource. Each PRB information word may further be represented by PRB origin location information and PRB end location information, PRB start location information and PRB quantity information, PRB origin location information and bandwidth information, PRB quantity information and PRB end location information, PRB end location information and PRB quantity information, PRB end location information and bandwidth information, bitmap, etc. In this case, the PRB information word corresponds to multiple PRB resources. For example, it may correspond to a number of consecutive PRBs. Optionally, each PRB information word may correspond to a particular frequency point, a particular frequency band, a particular cell group, a particular frequency band combination, a particular cell, etc.

[0097] Alternatively, the following examples may be specific examples of each of the above PRB information words.

[0098] As an example, the candidate PRB information may be PRB origin location information and PRB end location information, in which case the terminal considers all frequency domain resources from the PRB corresponding to the PRB origin location information to the PRB corresponding to the PRB end location information to be candidate PRB resources for IDC problem detection. Alternatively, the candidate PRB information may be PRB origin location information and PRB quantity information (e.g., N), in which case the terminal considers N consecutive PRBs from the PRB corresponding to the PRB origin location information to be candidate PRB resources for IDC problem detection. Alternatively, the candidate PRB information may be PRB end location information and PRB quantity information (e.g., N), in which case the terminal considers N consecutive PRBs from the PRB corresponding to the PRB end location information to be candidate PRB resources for IDC problem detection.

[0099] As another example, the candidate PRB information may be a PRB bitmap. For example, a bit position of the PRB bitmap corresponds to a specific candidate PRB resource. The bitmap may be designed to map one by one to the bit positions in the bitmap in the order of PRB ID or PRB index. In this example, one bit position corresponds to a PRB resource of a specific PRB ID or PRB index. When the bit position is set to a specific value, it indicates that the PRB resource corresponding to the bit position is a candidate PRB resource for IDC problem detection. For example, the protocol may specify that a value of the bit position is "1" to inform the terminal that the PRB corresponding to the bit position is a candidate PRB resource for IDC problem detection. The protocol may specify that a value of the bit position is "0" to inform the terminal that the PRB corresponding to the bit position is not a candidate PRB resource for IDC problem detection.

[0100] It should be noted that the network side equipment may further configure frequency point information (e.g., frequency point identifier) ​​and / or BWP information (BWP identifier) ​​and / or cell information (cell identifier) ​​and / or frequency band information (frequency band identifier) ​​corresponding to the above candidate PRB information.

[0101] Here, the BWP identifier indicates the bandwidth portion BWP to which the frequency domain resource corresponding to the above PRB information belongs, and is used to notify the network side equipment of candidate PRB resources for detecting an IDC problem in the bandwidth portion corresponding to the BWP ID.

[0102] Cell identification information, where the cell identifier indicates the cell to which the frequency domain resource corresponding to the PRB information belongs, and is used to notify the network side device of candidate PRB resources for IDC problem detection in the frequency domain resource corresponding to the cell ID.

[0103] Frequency band identification information, where the frequency band identification information indicates a frequency band to which a frequency domain resource corresponding to the PRB information belongs, and is used to notify a network side device of candidate PRB resources for detecting an IDC problem in the frequency domain resource corresponding to the frequency band identifier.

[0104] It should be noted that the frequency domain resources corresponding to the above candidate BWP information and candidate PRB information may be frequency domain resources corresponding to the serving frequency point of the terminal, or may be frequency domain resources corresponding to the non-serving frequency point of the terminal.

[0105] Optionally, before the network side device provides reporting configuration information of interference support information, the method further includes the terminal sending capability information to the network side device; The capacity information is First capability indication information supporting reporting of BWP level interference support information; The second capability indication information includes at least one item of second capability indication information that supports reporting of PRB-level interference support information.

[0106] Specifically, the terminal may report one or more of the following capability information to the network side device: Capability indication information supporting reporting of BWP-level interference supporting information. For example, when a terminal reports capability information, the first capability indication information is included in the transmission, or the first capability indication information to be included is set to a specified value, indicating that the terminal supports reporting of BWP-level interference supporting information. Capability indication information supporting reporting of PRB-level interference supporting information. For example, when a terminal reports capability information, the terminal transmits the second capability indication information including the second capability indication, or when the second capability indication information to be included is set to a specified value, the second capability indication indicates that the terminal supports reporting of PRB-level interference supporting information.

[0107] In the above embodiment, the terminal reports capability information supporting reporting of BWP level and / or PRB level interference support information, and the network side equipment can perform reporting configuration of interference support information to the terminal based on the capability information reported by the terminal, which is low in implementation complexity.

[0108] In one embodiment, as shown in FIG. 2, the method includes: The method further includes a step of receiving interference cancellation configuration information sent by the terminal from the network side device, the interference cancellation configuration information including at least one of BWP interference cancellation configuration information and PRB interference cancellation configuration information, and a step of the terminal performing an interference cancellation action based on the interference cancellation configuration information.

[0109] Optionally, the BWP interference cancellation configuration information is used to instruct a terminal to stop transmitting and receiving data on a BWP resource corresponding to the BWP interference cancellation configuration information, or the BWP interference cancellation configuration information is used to instruct a terminal to perform BWP switching, and the PRB interference cancellation configuration information is used to instruct a terminal to stop transmitting and receiving data on a PRB resource corresponding to the PRB interference cancellation configuration information.

[0110] Specifically, the terminal obtains interference cancellation configuration information and performs interference cancellation behavior based on the interference cancellation configuration information. Here, the interference cancellation configuration information is determined by the network side based on the interference support information reported by the terminal and transmitted to the terminal. The interference cancellation configuration information is used to support the terminal in handling the IDC problem. Here, the interference cancellation configuration information includes one or more pieces of information as follows: BWP interference cancellation configuration information. Here, the BWP interference cancellation configuration information is used to instruct a terminal to stop transmitting and receiving data on a BWP resource corresponding to the BWP interference cancellation configuration information. Or, the BWP interference cancellation configuration information is used to instruct a terminal to perform BWP switching. PRB interference cancellation configuration information, where the PRB interference cancellation configuration information is used to instruct a terminal to stop transmitting and receiving data on a PRB resource corresponding to the PRB interference cancellation configuration information.

[0111] In the above embodiment, when an IDC problem occurs, the terminal reports interference support information to the network side to support the network in handling the IDC problem, the network side device sends interference resolution configuration information based on the interference support information, and the terminal performs interference resolution action based on the interference resolution configuration information, where the interference support information reported by the terminal is at the BWP level and / or PRB level, that is, the interference support information reported by the terminal is detailed up to the BWP and / or PRB, so that the network side can handle the IDC problem with finer granularity of interference support information, and the resource utilization rate is improved.

[0112] In an embodiment of the present application, the network side device controls the terminal to report BWP and / or PRB level interference support information according to the on / off control information, where the on / off control information may be explicit control information or implicit control information, for example, including: Method 1 (explicit): A few bits instruct the terminal whether to turn on reporting of BWP and / or PRB level interference support information, or whether to turn on reporting of BWP and / or PRB level interference support information for a target candidate resource (which may be indicated in an existing candidate frequency list or a new candidate frequency list). Method 2 (explicit): Using target candidate frequency information and a bitmap, the terminal is instructed as to whether to turn on reporting of BWP and / or PRB level interference support information, or whether to turn on reporting of BWP and / or PRB level interference support information for a target candidate resource (which may be indicated in an existing candidate frequency list or a new candidate frequency list). Method 3 (implicit): Candidate resource information that cannot report BWP and / or PRB level interference support information is added to the R16 candidate frequency list. The R18 candidate frequency list is newly increased, and frequencies that support reporting BWP and / or PRB level interference support information are added to the subsequent frequency list newly introduced in R18. Different lists are used to distinguish which frequencies support reporting BWP and / or PRB level interference support information.

[0113] Furthermore, the granularity configuration information may also implicitly indicate whether to turn on reporting of BWP and / or PRB level interference supporting information, or whether to turn on reporting of BWP and / or PRB level interference supporting information for a target candidate resource (which may be indicated in an existing candidate frequency list or a new candidate frequency list).

[0114] In one embodiment, when the on / off control field is included in the broadcast configuration information and the value of the on / off control field is a first target value, if an IDC problem occurs, the terminal broadcasts interference support information at a BWP level and / or a PRB level; or When the on / off control field is included in the reporting configuration information, and the value of the on / off control field is a first target value, if an IDC problem occurs in a resource corresponding to the target candidate resource information, the terminal reports interference support information at a BWP level and / or a PRB level; or When the reporting configuration information includes the on / off control field and the value of the on / off control field is a first bitmap, if an IDC problem occurs, the terminal reports interference support information at a BWP level and / or a PRB level according to the first bitmap and the target candidate resource.

[0115] Optionally, the terminal broadcasts interference support information at a BWP level and / or a PRB level based on the broadcast configuration information, When the on / off control information is included in the reporting configuration information, the terminal reports interference support information of a BWP level and / or a PRB level based on the on / off control information; When the granularity arrangement information is included in the report arrangement information, the terminal reports interference support information of a BWP level and / or a PRB level based on the granularity arrangement information; When the target candidate resource information is included in the reporting configuration information, the terminal reports interference support information at a BWP level and / or a PRB level based on the target candidate resource information.
