Description

Detection capability determination method, device, equipment and storage medium Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and specifically to a detection capability determination method, apparatus, device, and storage medium. Background Art

[0002] In a multi-carrier scenario, one Downlink Control Information (DCI) / Physical Downlink Control Channel (PDCCH) can schedule one carrier. If a large number of carriers are configured, or if many DCI / PDCCHs need to be sent simultaneously, PDCCH resources may be scarce. To reduce PDCCH load, one DCI / PDCCH is typically used to schedule multiple carriers.

[0003] Based on this, if a DCI / PDCCH can schedule multiple carriers, how to determine the detection capability allocated to the DCI / PDCCH detection for scheduling multiple carriers is an urgent problem to be solved.

It can also ensure that channel feedback request indications are not lost, allowing terminal devices to report channel status measurements in a timely manner, allowing network devices to adjust scheduling parameters in a timely manner based on channel changes.

[0030] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] FIG1 is a schematic diagram of an exemplary network architecture provided in an embodiment of the present application.

[0032] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0033] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0034] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (eg, UE) located within the coverage area.

[0035] The network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, an access point, an in-vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0036] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0037] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, an IoT device, a satellite handheld terminal, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolution network, etc.

[0038] The terminal device 110 can be used for device-to-device (D2D) communication.

[0039] The functional units in the communication system 100 may also establish connections and implement communication via next generation (NG) network interfaces.

[0040] Figure 1 shows a network device and two terminal devices. In some embodiments, the wireless communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area, which is not limited in this embodiment of the present application.

[0041] It should be noted that FIG1 is only an example of a system to which this application is applicable. Of course, the method shown in the embodiment of this application can also be applied to other systems. In addition, the terms "system" and "network" are used interchangeably in this article.

[0042] It should be understood that the term "and / or" in the embodiments of this application is merely a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0043] It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), and the present application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0044] In 5G communication systems, terminal devices can determine the maximum Physical Downlink Control Channel (PDCCH) detection capability supported by each scheduled carrier in its corresponding scheduled carrier based on the carriers configured by the network equipment. The PDCCH detection capability can be expressed as the number of blind PDCCH detections, the number of blindly detected PDCCH candidates, or the number of non-overlapping Control Channel Elements (CCEs) used for channel estimation.

[0045] In some embodiments, the total detection capability parameter value of the scheduled carrier with the subcarrier spacing configured as μ is recorded as M_total, and the calculation formula of M_total satisfies formula (1):

[0046]

[0047] in, The number of carriers supported by the terminal device for detection; M_max is the single-carrier PDCCH detection capability parameter value; The number of scheduled carriers configured with a subcarrier spacing of μ for the scheduled carrier; The sum of the number of scheduled carriers whose subcarrier spacing of the scheduled carrier is configured as j.

[0048] Based on formula (1), the maximum PDCCH detection capability parameter value supported by each scheduled carrier on its corresponding scheduling carrier can be determined, that is, min(M_max, M_total).

[0049] In a multi-carrier scenario, one downlink control information (DCI) / PDCCH can schedule one carrier. If a large number of carriers are configured, or if a large number of DCI / PDCCHs need to be sent simultaneously, PDCCH resources may be scarce. To reduce the PDCCH load, one DCI / PDCCH is usually used to schedule multiple carriers. The carrier combinations scheduled by the same DCI / PDCCH are preconfigured or predefined.

[0050] In some embodiments, the detection capability of a DCI / PDCCH that can schedule multiple carriers is attributed to one carrier among all carriers that can be scheduled by the DCI.

[0051] It should be noted that if a DCI / PDCCH can schedule multiple carriers, how to determine the detection capability allocated to the DCI / PDCCH detection for scheduling multiple carriers is an issue that needs to be solved urgently.

[0052] Based on this, an embodiment of the present application provides a detection capability determination method, which can determine the detection capability parameter value for detecting a first DCI format based on a first detection capability parameter value and a second detection capability parameter value, and the first DCI format can be used to schedule multiple carriers in a first carrier set. In this way, the detection capability parameter value of the first DCI format that can schedule multiple carriers can be determined based on the first detection capability parameter value and the second detection capability parameter value. In this way, clarifying the detection capability of the multi-carrier scheduling DCI format (i.e., the first DCI format) can further optimize the blind detection process of the terminal device. In addition, the terminal device can use this method to determine the detection capability parameter value for detecting the first DCI format, such as the number of blind detections, the number of PDCCH candidates for blind detection, and the number of non-overlapping CCEs for channel estimation; the network device uses this method to determine the detection capability parameter value for the terminal device for detecting the first DCI format, which helps the network device to configure an appropriate number of PDCCH transmission resources, such as the control resource set (CORESET), the search space set (Search Space Set), or the number of PDCCH candidates (PDCCH candidate), so that the number of PDCCHs that can be transmitted will not exceed the detection capability of the terminal device, avoiding the situation where some PDCCHs cannot be detected due to insufficient detection capability of the terminal device, thereby improving system performance.

[0053] For example, it can ensure that scheduling information is not lost, allowing terminal devices to transmit data in a timely manner. It can also ensure that channel feedback request indications are not lost, allowing terminal devices to report channel status measurements in a timely manner, allowing network devices to adjust scheduling parameters in a timely manner based on channel changes.

[0054] It should be noted that the first DCI format and the second DCI format are mentioned many times in the following embodiments. The DCI format that can schedule multiple carriers is recorded as the first DCI format, such as DCI format 0_X and / or 1_X, and the DCI format that can schedule one carrier is recorded as the second DCI format, such as DCI format 0_0 / 0_1 / 0_2 / 1_0 / 1_1 / 1_2.

[0055] It should also be noted that the execution subject in the embodiments of the present application can be a network device or a terminal device, and the embodiments of the present application do not specifically limit the execution subject.

[0056] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0057] FIG2 is a flow chart of a method for determining detection capability provided in an embodiment of the present application. As shown in FIG2 , the method may include the following contents.

[0058] S210. Determine, based on the first detection capability parameter value and the second detection capability parameter value, a detection capability parameter value for detecting a first DCI format, where the first DCI format is used to schedule multiple carriers in a first carrier set; wherein the first detection capability parameter value is a single-carrier detection capability parameter threshold corresponding to the first carrier; and the second detection capability parameter value is a detection capability parameter threshold of a DCI format for detecting and scheduling carriers in a second carrier set.

[0059] The first carrier is one of the first carrier set.

[0060] For example, if the first carrier set is {cell1, cell2, cell3, cell4}, the first carrier may be one of cell1, cell2, cell3, and cell4.

[0061] Exemplarily, the first carrier is any one of the following in the first carrier set: a carrier whose identification information is a specified identifier, a carrier whose search space set (Searchspace Set) configuration number satisfies a first preset rule, a carrier whose number of Searchspace Sets supporting single carrier scheduling satisfies a second preset rule, a carrier configured for calculating the detection capability parameter value of the first DCI format, a carrier configured to support the first DCI format, a carrier that counts the DCI size of the first DCI format, and a protocol predefined.

[0062] It should be noted that the carrier whose identification information is a specified identifier can be the carrier with the smallest cell identification (Identity Document, ID) in the first carrier set, or the carrier with the largest cell ID in the first carrier set, or the carrier with other cell identifications in the first carrier set. This embodiment of the present application does not limit this.

[0063] It should also be noted that the first preset rule is that the number of Searchspace Set configurations is the least, or the first preset rule is that the number of Searchspace Set configurations is the largest. The second preset rule is that the number of Searchspace Set configurations supporting single-carrier scheduling is the least, or the second preset value is that the number of Searchspace Set configurations supporting single-carrier scheduling is the largest, and this embodiment of the present application is not limited to this.

[0064] It should also be noted that the carrier whose number of Searchspace Set configurations meets the first preset rule can be the carrier with the least number of Searchspace Set configurations, or it can be the carrier when the number of Searchspace Set configurations is other values. This embodiment of the present application is not limited to this.

[0065] It should also be noted that the carrier whose number of Searchspace Sets supporting single-carrier scheduling meets the second preset rule may be the carrier with the least number of Searchspace Set configurations supporting single-carrier scheduling, or the carrier with other values ​​of Searchspace Set configurations supporting single-carrier scheduling. The embodiment of the present application is not limited to this.

[0066] It should also be noted that the carrier configured for calculating the detection capability of the first DCI format can be the carrier configured by the network device through RRC signaling for calculating the detection capability of the first DCI format, or it can be the carrier configured by the network device through other signaling for calculating the detection capability of the first DCI format. This embodiment of the present application is not limited to this.

[0067] The second carrier set includes the first carrier set.

[0068] It should be understood that, for the terminal device, the second carrier set may be configured for the terminal device by the network device.

[0069] It should be understood that for the terminal device, the second carrier set is determined based on the carrier configured to the terminal device, the subcarrier spacing of the scheduled carrier corresponding to each carrier in the second carrier set is the same, and the second carrier set includes the first carrier set.

[0070] It should also be understood that the DCI format for scheduling carriers in the second carrier set may be a DCI format for scheduling multiple carriers or a DCI format for scheduling a single carrier.

[0071] It should also be understood that the first detection capability parameter value may be the maximum detection capability parameter value supported by the first carrier when the subcarrier spacing is configured as μ.

[0072] In some embodiments, determining the detection capability parameter value for detecting the first DCI format based on the first detection capability parameter value and the second detection capability parameter value may include: determining the detection capability parameter value for detecting the first DCI format based on the minimum value of the first detection capability parameter value and the second detection capability parameter value.

[0073] Exemplarily, the first detection capability parameter value is recorded as M_max, and the second detection capability parameter value is recorded as M_total. Then the detection capability parameter value used by the terminal device or network device to detect the first DCI format can be the minimum value of M_max and M_total, that is, min(M_max, M_total).

[0074] In some embodiments, the subcarrier spacing of the scheduled carriers of each carrier in the second carrier set is the same.

[0075] It should be noted that a scheduling carrier is a carrier that can schedule other carriers. In this case, the other carriers are called scheduled carriers. For example, assuming that cell1 is the scheduling carrier and can schedule itself and cell2, cell1 is both the scheduling carrier and the scheduled carrier, and cell2 is the scheduled carrier.

[0076] It should also be noted that, for multiple scenarios, there may be multiple scheduling carriers of the scheduled carrier; in the current scenario, the scheduling carrier of the scheduled carrier is unique.

[0077] Exemplarily, the second carrier set is {cell1, cell2, cell3, cell4, cell5}. Assuming that cell1 is a scheduled carrier, the scheduled carriers of cell1, cell2, cell3, cell4, and cell5 are all cell1. At this time, the subcarrier spacing of the scheduled carriers (i.e., cell1) of cell1, cell2, cell3, cell4, and cell5 is the same, which is the subcarrier spacing of cell1.

[0078] In some embodiments, the first detection capability parameter value may be a single-carrier PDCCH detection capability parameter value corresponding to the first carrier.

[0079] In some embodiments, the first detection capability parameter value may be determined based on the subcarrier spacing of the first carrier, or the first detection capability parameter value may be determined based on the subcarrier spacing of a scheduling carrier of the first carrier.

[0080] Exemplarily, according to a predefined protocol, the subcarrier spacing of the first carrier corresponds to the first detection capability parameter value. For example, the subcarrier spacing of the first carrier corresponds to the first detection capability parameter value one-to-one, and the first detection capability parameter value can be uniquely determined based on the subcarrier spacing of the first carrier.

[0081] Exemplarily, according to a protocol pre-definition, the subcarrier spacing of the scheduled carrier of the first carrier corresponds to the first detection capability parameter value. For example, the subcarrier spacing of the scheduled carrier of the first carrier corresponds to the first detection capability parameter value one-to-one, and the first detection capability parameter value can be uniquely determined based on the subcarrier spacing of the scheduled carrier of the first carrier.

[0082] It should be understood that when the first carrier serves as a scheduling carrier, the first detection capability parameter value may be determined according to the subcarrier spacing of the scheduling carrier, that is, the subcarrier spacing of the first carrier itself.

[0083] Exemplarily, assuming that the first carrier set is {cell1, cell2, cell3, cell4}, the first carrier is cell1, and cell1 is a scheduled carrier, the first detection capability parameter value can be determined according to the subcarrier spacing of cell1.

[0084] It should also be understood that when the first carrier serves as a scheduled carrier, the first detection capability parameter value can be determined based on the subcarrier spacing of the scheduled carrier, that is, the subcarrier spacing of the first carrier itself, or the first detection capability parameter value can be determined based on the subcarrier spacing of the scheduling carrier of the scheduled carrier.

[0085] For example, assuming that the first carrier set is {cell1, cell2, cell3, cell4}, the first carrier is cell1, and the scheduling carrier is cell2, then cell2 is both a scheduling carrier and a scheduled carrier, and cell1 is a scheduled carrier. In this case, the first detection capability parameter value can be determined based on the subcarrier spacing of cell1, or based on the subcarrier spacing of cell2, the scheduling carrier of cell1.

[0086] In some embodiments, the second detection capability parameter value may be determined according to the number of supported detection carriers and the configured multiple carriers.

[0087] It should be noted that the number of detection carriers supported by the terminal device can be reported to the network device through signaling, and the network device can determine the number of detection carriers supported by the terminal device based on the reported value.

[0088] Furthermore, in some embodiments, the second detection capability is determined according to the number of supported detection carriers, a single carrier detection capability parameter threshold, the first value, and the second value.

[0089] The first value is determined based on the number of carriers corresponding to the second carrier set, and the number of carriers corresponding to the second carrier set is determined according to the count value of each carrier;

[0090] The second value is determined based on the number of carriers of the configured multiple carriers, the number of carriers of the configured multiple carriers is determined according to the count value of each carrier, and the configured multiple carriers include a second carrier set.

[0091] It should be noted that, in the embodiment of the present application, the number of carriers is not necessarily the same as the number of carriers.

[0092] For example, assuming that there are 3 carriers in a carrier set (such as the first carrier set and the second carrier set), and the count value of each carrier in the 3 carriers is 1, then according to the count value of each carrier in the 3 carriers, it can be determined that the number of carriers corresponding to the set is 3.

[0093] For another example, assuming that there are 3 carriers in the carrier set, the count value of one of the 3 carriers is 2, and the count values ​​of the remaining 2 carriers are 1, then the number of carriers corresponding to the set is 4.

[0094] For another example, assuming that there are 3 carriers in the carrier set, the count value of one of the 3 carriers is 2, and the count values ​​of the remaining 2 carriers are 1.5, then the number of carriers corresponding to the set is 5.

[0095] Exemplarily, the second detection capability parameter value may be determined according to the number of supported detection carriers, the sum of count values ​​of each carrier in the second carrier set, and the sum of count values ​​of each carrier in the configured multiple carriers.

[0096] Further, for example, the second detection capability parameter value can be determined according to the number of supported detection carriers, the first detection capability, the sum of the count values ​​of each carrier in the second carrier set, and the sum of the count values ​​of each carrier in the configured multiple carriers.

[0097] The configured multiple carriers may include a second carrier set.

[0098] It should be understood that the sum of the count values ​​of each carrier in the configured multiple carriers includes the sum of the count values ​​of each carrier in the second carrier set.

[0099] Exemplarily, assuming that μ is a subcarrier spacing configuration, it can take one of the values ​​0, 1, 2, and 3.

[0100] It should be understood that the value of μ is only used to distinguish different subcarrier spacings and does not represent the actual subcarrier spacing. For example, a μ value of 0 corresponds to a subcarrier spacing of 15 kHz, a μ value of 1 corresponds to a subcarrier spacing of 30 kHz, a μ value of 2 corresponds to a subcarrier spacing of 60 kHz, and a μ value of 3 corresponds to a subcarrier spacing of 120 kHz.

[0101] Exemplarily, the subcarrier spacing configuration of the scheduled carrier of each carrier in the second carrier set is 0, and the sum of the count values ​​of each carrier in the second carrier set is recorded as Then the sum of the count values ​​of each carrier in the configured multiple carriers can be The sum of

[0102] It should also be noted that the count value of each carrier in the second carrier set may be the count value of the scheduled carrier whose subcarrier spacing of the scheduling carrier is configured as μ.

[0103] Exemplarily, assuming that the second carrier set is {cell1, cell2, cell3, cell4}, and cell1 is the scheduling carrier, then cell1, cell2, cell3, and cell4 are all scheduled carriers, and the scheduling carriers of cell1, cell2, cell3, and cell4 are all cell1. Assuming that the subcarrier spacing of cell1 is configured as μ, the subcarrier spacing of the scheduling carriers (i.e., cell) of cell1, cell2, cell3, and cell4 are all μ. That is to say, the scheduled carriers whose subcarrier spacing of the scheduling carrier (i.e., cell1) is configured as μ are cell1, cell2, cell3, and cell4. At this time, the count value of each carrier in {cell1, cell2, cell3, and cell4} is the count value of cell1, cell2, cell3, and cell4.

[0104] It should also be understood that the number of carriers supported for detection is the number of carriers supported for detection by the terminal device, which can be used to characterize the PDCCH carrier detection capability reported by the terminal device. The terminal device can report the number of carriers supported for detection to the network device.

[0105] It should also be understood that the configured multiple carriers are multiple carriers configured by the network device, and the network device can configure multiple carriers for the terminal device.

[0106] It should be noted that in the embodiments of the present application, the count value can also be understood as a weight value. For example, the count value of cell 1 being 2 means the weight value of cell 1 is 2, and does not refer to the actual number of cells 1.

[0107] In some embodiments, the count value of each carrier in the configured multiple carriers can be used to represent the impact of each carrier on the second detection capability. That is, different count values ​​of each carrier in the configured multiple carriers result in different second detection capabilities.

[0108] In some embodiments, the count value of each carrier in the configured multiple carriers may be determined in the following two possible implementations.

[0109] In one possible implementation, the count value of each carrier in the configured multiple carriers may be: the count value of the first carrier is 1+x, and the count values ​​of the other carriers in the configured multiple carriers except the first carrier are determined according to any one of the following:

[0110] The count values ​​are all 1-y;

[0111] The count values ​​are all 1-x / (M-1);

[0112] The count values ​​are all 1-x / (N-1).

[0113] Specifically, in some embodiments, the count value of each carrier in the configured multiple carriers may also be determined according to any one of the following:

[0114] (a) The count value of the first carrier is 1, and the count value of each of the other carriers is 1.

[0115] It should be noted that in this item, the detection capability parameter value used by the terminal device or network device to detect the first DCI format belongs to the first carrier and has no effect on other carriers.

[0116] (b) The count value of the first carrier is 2, and the count value of each of the other carriers is 1.

[0117] It should be noted that in this item, the first carrier set is regarded as one carrier, and shares the detection capability parameter value with other carriers.

[0118] (c) The count value of the first carrier is 1+x, and the count values ​​of the other carriers are all 1.

[0119] It should be noted that, in this item, the first carrier set is regarded as one carrier, but the impact on the detection capability parameter values ​​of other carriers is determined according to x.

[0120] (d) The count value of the first carrier is 1+x, and the count values ​​of the other carriers are all 1-y.

[0121] It should be noted that in this item, the first carrier set is regarded as one carrier, but the impact on the detection capability parameter values ​​of other carriers is determined according to x and y.

[0122] (e) The count value of the first carrier is 1+x, and the count values ​​of the other carriers are all 1-x / (M-1).

[0123] It should be noted that in this item, the first carrier set is regarded as one carrier, but it only affects the detection capability parameter values ​​of other carriers in the first carrier set, and has no effect on the detection capability parameter values ​​of carriers outside the first carrier set.

[0124] (f) The count value of the first carrier is 1+x, and the count values ​​of the other carriers are all 1-x / (N-1).

[0125] In another possible implementation, the count value of each carrier in the configured multiple carriers may be: the count value of the first carrier set is x, and the count value of each carrier in the configured multiple carriers is determined according to any one of the following:

[0126] The count values ​​are all 1-y;

[0127] The count values ​​are all 1-x / M;

[0128] The count values ​​are all 1-x / N.

[0129] Specifically, in some embodiments, the count value of each carrier in the configured multiple carriers may also be determined according to any one of the following:

[0130] (g) The count value of the first carrier set is 1, and the count value of each carrier in the other carriers is 1.

[0131] (h) The count value of the first carrier set is x, and the count value of each carrier in the other carriers is 1.

[0134] (k) The count value of the first carrier set is x, and the count value of each carrier in the other carriers is 1-x / N.

[0135] It should be noted that in (a) to (k), x and y can be configured, or x and y can be predefined by the protocol; M and N can be configured, or M and N can be predefined by the protocol, or M can be the number of carriers in the first carrier set, and N can be the number of carriers in the configured multiple carriers.

[0136] It should be noted that the embodiment of the present application does not limit the values ​​of x and y. x can be a positive number, a negative number, or 0. x can be an integer or a non-integer.

[0137] Exemplarily, the value of x satisfies 0<=x<=1, and / or the value of y satisfies 0<=y<=1.

[0138] It should be understood that the method of determining the count value of each carrier among the multiple carriers configured by the network device in (a) to (k) is an exemplary description, and there may be other ways to determine the count value of each carrier among the multiple carriers configured by the network device, and the embodiments of the present application are not limited to this.

[0139] It should also be understood that the other carriers in (a) to (k) can be other carriers in the first carrier set except the first carrier, or can be carriers in the second carrier set except the first carrier, that is, other carriers in all carriers with the same subcarrier spacing configuration as the first carrier among the multiple carriers configured by the network device except the first carrier, or can be other carriers in the multiple carriers configured by the network device except the first carrier.

[0140] For example, in the embodiment of the present application, the calculation formula of the second detection capability parameter value satisfies formula (2):

[0141]

[0142] Where μ is the subcarrier spacing configuration, which can take one of the values ​​0, 1, 2, and 3; is the number of carriers supported by the terminal device for detection; M_max is the first detection capability parameter value; is the sum of the count values ​​of each carrier in the second carrier set; The sum of the count values ​​of each carrier in multiple carriers configured for the network device.

For example, when μ = 0 and μ1 = 1, Determination and Similar, no further description is given here.

[0204] Based on this, an embodiment of the present application provides a detection capability determination method, which can determine the detection capability parameter value for detecting the first DCI format according to the first detection capability parameter value and the second detection capability parameter value, and the first DCI format can be used to schedule multiple carriers in the first carrier set. In this way, the detection capability parameter value of the first DCI format that can schedule multiple carriers can be determined based on the first detection capability parameter value and the second detection capability parameter value. In this way, the detection capability of the multi-carrier scheduling DCI format (i.e., the first DCI format) is clarified, and the blind detection process of the terminal device can be further optimized. In addition, the terminal device can use this method to determine the detection capability parameter value for detecting the first DCI format, such as the number of blind detections, the number of PDCCH candidates for blind detection, and the number of non-overlapping CCEs for channel estimation; the network device uses this method to determine the detection capability parameter value of the terminal device for detecting the first DCI format, which helps the network device to configure the appropriate number of PDCCH transmission resources, such as the number of control resource sets (CORESET) and the number of search space sets (Search Space Set), so that the number of PDCCHs that can be transmitted will not exceed the detection capability of the terminal device, thereby improving system performance.

[0205] For example, it can ensure that scheduling information is not lost, allowing terminal devices to transmit data in a timely manner. It can also ensure that channel feedback request indications are not lost, allowing terminal devices to report channel status measurements in a timely manner, allowing network devices to adjust scheduling parameters in a timely manner based on channel changes.

[0206] In another embodiment of the present application, based on the detection capability determination method described in the aforementioned embodiment, the embodiment of the present application includes multiple ways to determine the detection capability parameter value for detecting the first DCI format according to the first detection capability parameter value and the second detection capability parameter value.

[0207] In some embodiments, the detection capability parameter value for detecting the first DCI format may be determined based on the maximum value of the first detection capability parameter value and the second detection capability parameter value. That is, the detection capability parameter value for detecting the first DCI format may be max(M_max, M_total).

[0208] In some embodiments, the detection capability parameter value for detecting the first DCI format may be determined based on the minimum value of the first detection capability parameter value and the second detection capability parameter value. That is, the detection capability parameter value for detecting the first DCI format may be min(M_max, M_total).

[0209] In some embodiments, as shown in FIG3 , the method may include:

[0210] S310, determining a detection capability parameter value for detecting a first DCI format according to a first detection capability parameter value, a second detection capability parameter value, and a first proportional coefficient, wherein the first proportional coefficient is configured or predefined by a protocol.

[0211] It should be noted that the first proportionality coefficient may be used to determine a proportional relationship between the detection capabilities of the second DCI format and the first DCI format.

[0212] The second DCI format may be used to schedule the first carrier, that is, the second DCI format is a DCI format for scheduling one carrier.

[0213] The value of the first proportional coefficient may satisfy 0<=first proportional coefficient<=1.

[0214] Where a is the proportional coefficient used to determine the detection capability of the first DCI format, and the remaining capability is used to determine the detection capability of the second DCI format. Allocating the detection capability of the first DCI format and the detection capability of the second DCI format according to the configuration (i.e., the first proportional coefficient) can ensure a clear capability allocation between the detection capability of the first DCI format and the detection capability of the second DCI format, which is beneficial to the implementation and optimization of the terminal blind detection process.

[0215] In a possible implementation, the detection capability parameter value for detecting the first DCI format may be determined based on a minimum value between the first detection capability parameter value and the second detection capability parameter value, and a first proportional coefficient.

[0216] For example, the detection capability parameter value for detecting the first DCI format may be determined based on the product of the minimum value between the first detection capability parameter value and the second detection capability parameter value and the first proportionality coefficient. Alternatively, the detection capability parameter value for detecting the first DCI format may be determined based on the quotient of the minimum value between the first detection capability parameter value and the second detection capability parameter value and the first proportionality coefficient.

[0217] In another possible implementation, the detection capability parameter value for detecting the first DCI format may be determined based on the maximum value of the first detection capability parameter value and the second detection capability parameter value, and the first proportional coefficient.

[0218] For example, the detection capability parameter value for detecting the first DCI format may be determined based on the product of the maximum value between the first detection capability parameter value and the second detection capability parameter value and the first proportionality coefficient. Alternatively, the detection capability parameter value for detecting the first DCI format may be determined based on the quotient of the maximum value between the first detection capability parameter value and the second detection capability parameter value and the first proportionality coefficient.

[0219] Furthermore, in an embodiment of the present application, a detection capability parameter value for detecting the second DCI format can also be determined based on the first detection capability parameter value, the second detection capability parameter value and the second proportional coefficient, wherein the sum of the second proportional coefficient and the first proportional coefficient is 1.

[0220] Exemplarily, the first detection capability parameter value is recorded as M_max, the second detection capability parameter value is recorded as M_total, the first proportional coefficient is a, and the second proportional coefficient is 1-a. The terminal device or network device can then determine that the detection capability parameter value for detecting the first DCI format can be a portion of the minimum value of M_max and M_total, that is, a*(min(M_max, M_total)). At this time, the terminal device or network device can determine that the detection capability parameter value for detecting the second DCI format can be (1-a)*min(M_max, M_total).

[0221] In the detection capability determination method provided in the embodiment of the present application, the detection capability parameter value for detecting the first DCI format can be determined based on the first detection capability parameter value, the second detection capability parameter value and the first proportional coefficient, and the first DCI format can be used to schedule multiple carriers in the first carrier set. In this way, the detection capability parameter value of the first DCI format that can schedule multiple carriers can be determined based on the first detection capability parameter value, the second detection capability parameter value and the first proportional coefficient. In this way, while clarifying the detection capability of the multi-carrier scheduling DCI format (i.e., the first DCI format), the detection capability of the single-carrier scheduling DCI format (i.e., the second DCI format) can also be clarified, so that the first DCI format that can schedule multiple carriers can be distinguished from the second DCI format that can schedule one carrier, which is beneficial to the implementation and optimization of the blind detection process of the terminal device. In addition, the terminal device can use this method to determine the detection capability parameter value for detecting the first DCI format, such as the number of blind detections, the number of PDCCH candidates for blind detection, and the number of non-overlapping CCEs for channel estimation; the network device uses this method to determine the detection capability parameter value for detecting the first DCI format, which helps the network device to configure an appropriate number of PDCCH transmission resources, such as the number of control resource sets (CORESETs), the number of search space sets (Search Space Sets) or the number of PDCCH candidates (PDCCH candidates), so that the number of PDCCHs that can be transmitted will not exceed the detection capability of the terminal device, thereby avoiding the situation where some PDCCHs cannot be detected due to insufficient detection capability of the terminal device, thereby improving system performance.

[0222] For example, scheduling information can be ensured not to be lost, allowing the terminal device to transmit data in a timely manner. Channel feedback request indications can be ensured not to be lost, allowing the terminal device to report channel state measurement results in a timely manner, allowing the network device to adjust scheduling parameters in a timely manner based on channel change status. In an embodiment of the present application, the carrier simultaneously scheduled by DCI formats 0_X and / or 1_X can be at least one of a set consisting of multiple carriers, and the set consisting of multiple carriers can be the aforementioned first carrier set.

[0223] Exemplarily, the carrier configurations scheduled simultaneously by DCI formats 0_X and / or 1_X may be described in the following two exemplary embodiments.

[0224] In one example, the first carrier set is {cell1, cell2, cell3, cell4, cell5, cell6, cell7, cell8}, and the carrier configurations simultaneously scheduled by DCI formats 0_X and / or 1_X are shown in Table 1.

[0225] Table 1

[0226] Index number Carrier configuration 1 cell1+cell2 2 cell3+cell4 3 cell1+cell2+cell3 4 cell2+cell3+cell4 5 cell5+cell6 6 cell6+cell7 7 cell7+cell8 8 cell5+cell8 9 cell5+cell7 10 cell6+cell8 11 cell5+cell6+cell7 12 cell6+cell7+cell8

[0227] In another example, the first carrier set is {cell1, cell2, cell3, cell4}, and the carrier configurations scheduled simultaneously by DCI formats 0_X and / or 1_X are shown in Table 2.

[0228] Table 2

[0229] Index number carrier configuration 1 cell1+cell2 2 cell3+cell4 3 cell1+cell2+cell3 4 cell2+cell3+cell4

[0230] In an embodiment of the present application, when the terminal device or network device counts the blind detection capability of DCI / PDCCH for scheduling multiple carriers into one carrier, the detection capability parameter value allocated to the detection of DCI / PDCCH for scheduling multiple carriers can be divided from the detection capability parameter value allocated to the detection of DCI / PDCCH for scheduling one carrier, that is, the single-carrier scheduling detection capability parameter value and the multi-carrier scheduling detection capability parameter value are divided; it is also possible to clarify the number of blind detections corresponding to different DCI formats of the terminal device or network device, the number of PDCCH candidates for blind detection, the number of non-overlapping CCEs for channel estimation, and the network device configures an appropriate number of PDCCH transmission resources so that the number of PDCCHs that can be transmitted does not exceed the detection capability of the terminal device.

[0231] In addition, it is also possible to clarify the method of counting the value of each carrier in the multiple carriers configured by the network device when the terminal device or network device determines the detection capability parameter threshold of the scheduled carrier with different subcarrier intervals, and the method of counting the value of each carrier in the multiple carriers includes the method of counting the value of the scheduled carrier.
