Description

[0001] This application is a divisional application of the Chinese patent application with application number "201910944446.2", application date "September 30, 2019", and title "Information determination, adjustment method, threshold value usage method, terminal and storage medium". Technical Field

[0002] The present application relates to a wireless communication network, and in particular to an information determination and adjustment method, a threshold value use method, a terminal, and a storage medium. Background Art

[0003] Currently, the demands on 4G (the fourth generation mobile communication technology), LTE (Long-Term Evolution) / LTE-Advance / LTE-A (Long-Term Evolution Advance), and 5G (the fifth generation mobile communication technology) are increasing. Current development trends indicate that both 4G and 5G systems are designed to support enhanced mobile broadband, ultra-high reliability, ultra-low latency transmission, and massive connections.

[0004] In order to support the characteristics of ultra-high reliability and ultra-low latency transmission, it is necessary to transmit with a shorter transmission time interval and a lower code rate. The shorter transmission time interval can be a single or several Orthogonal Frequency Division Multiplexing (OFDM) symbols. For the Physical Downlink Control Channel (PDCCH), the relevant technology reduces the waiting time after the data arrives to ensure low-latency transmission by providing transmission opportunities at multiple occasions within the time slot, and ensures high-reliability transmission through high aggregation levels. In the current carrier aggregation system, the maximum number of detected PDCCH candidate sets and the maximum number of non-overlapping control channel elements (CCE) that the terminal needs to support are defined separately in each slot for each subcarrier interval. However, after the introduction of the enhanced terminal monitoring PDCCH capability, in the carrier aggregation scenario, no effective way to determine the second threshold value of each subcarrier interval in each time span has been proposed.

[0038] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0039] It should be noted that in the current NR system, the maximum number of detected PDCCH (physical downlink control channel) candidate sets and the maximum number of non-overlapping CCEs (control channel elements) that the terminal needs to support are defined separately in each slot for each subcarrier spacing, as shown in Table 1, where μ = 0, 1, 2, 3 represent subcarrier spacings of 15KHz, 30KHz, 60KHz, and 120KHz, respectively. For the sake of simplicity, the "maximum number of detected PDCCH candidate sets (also known as the maximum number of blind detections)" is referred to as "maximum BD", and the "maximum number of non-overlapping CCEs" is referred to as "maximum CCE value".

[0040] Table 1. Maximum number of candidate sets and CCEs per slot and per carrier (per slot per cell)

[0041]

[0042] In the carrier aggregation scenario, the maximum number of candidate sets and the maximum number of non-overlapping CCEs supported by the terminal do not always increase linearly with the increase in the number of aggregated carriers, but are affected by the number of carriers reported by the terminal. Support capability limitations. If the terminal is configured Downlink carrier, when When , the maximum number of candidate sets in each slot for each subcarrier spacing is The maximum number of non-overlapping CCEs in each slot for each subcarrier spacing is

[0043] When the enhanced terminal PDCCH monitoring capability was introduced, the maximum non-overlapping CCEs and the maximum number of detected PDCCH candidates per time span were defined. In carrier aggregation scenarios, when the terminal reports a limit on the number of carriers supported, the relevant technology does not provide an effective way to determine the thresholds for the maximum non-overlapping CCEs and the maximum number of detected PDCCH candidates per time span for each subcarrier spacing.

[0044] In view of this, an embodiment of the present application provides an information determination method to solve the above technical problems.

[0045] Figure 1 This is a flow chart of a method for determining information provided in an embodiment of the present application. The method can be executed by an information determination device. The information determination device can be implemented by software and / or hardware. Figure 1 As shown, the method includes:

[0046] Step S110: Acquire the number of carriers that meet the first set condition, the total number of downlink carriers, the number of carriers supported by the terminal as reported, and the first threshold.

[0047] Step S120: Determine a second threshold value of the target subcarrier spacing according to the number of carriers that meet the first setting condition, the total number of downlink carriers, the number of carriers supported by the terminal as reported, and the first threshold value.

[0048] It should be noted that the first setting condition includes at least one of the following: the subcarrier spacing of the main modulation carrier is the target subcarrier spacing; the subcarrier spacing of the main modulation carrier is the target subcarrier spacing and the time span pattern is obtained based on the same first parameter.

[0049] The target subcarrier spacing can be any one or more of the subcarrier spacings defined by the protocol. For example, μ is used to represent the subcarrier spacing, and different subcarrier spacings can be distinguished by the value of μ. Taking Table 1 as an example, μ = 0, 1, 2, and 3 represent subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, and 120 kHz, respectively.

[0050] Among them, the first parameter is the (X, Y) combination of the terminal reported candidates, and the first parameter can be expressed as Combination (X, Y). Exemplarily, the time span pattern (span pattern) in the time slot (slot) is determined by the (X, Y) set of the terminal reported candidates and the PDCCH control resource set CORESET and searchspace. Among them, overlap is not allowed between spans, and the interval between the starting points of two spans is not less than X symbols. Span duration (span duration) = Maximum (configured maximum CORESET duration, minimum Y reported by the terminal), and only the last span in the span pattern can be a shorter duration. The number of spans does not exceed floor (14 / X), where X is the minimum X in the Combination (X, Y) reported by the terminal. The optional Combination (X, Y) includes at least one of the following: (1, 1), (2, 1), (2, 2), (4, 1), (4, 2), (4, 3), (7, 1), (7, 2), (7, 3). Optionally, the (X, Y) set of candidates reported by the terminal may include at least one of the following: {(7, 3), (4, 3) and (7, 3), (2, 2), (4, 3) and (7, 3)}.

[0051] Taking the maximum number of non-overlapping CCEs as an example, when the enhanced terminal monitoring PDCCH capability is introduced, the maximum number of non-overlapping CCEs for each span is defined, as shown in Table 2.

[0052] Table 2 Maximum number of CCEs per span and per carrier (per span per cell)

[0053]

[0054] For example, assuming the target subcarrier spacing is 60 kHz, the number of carriers that meet the first setting condition may be the sum of all main modulated carriers whose subcarrier spacing is 60 kHz. For another example, assuming the target subcarrier spacing is 15 kHz, and the main carriers are divided into time span patterns according to (X, Y) = (2, 2) and (X, Y) = (4, 3), respectively, the number of carriers that meet the first setting condition may include: the sum of the main modulated carriers whose time span pattern is divided based on (X, Y) = (2, 2) and whose subcarrier spacing is 15 kHz, and the sum of the main modulated carriers whose time span pattern is divided based on (X, Y) = (4, 3) and whose subcarrier spacing is 15 kHz.

[0055] In the embodiment of the present application, the first threshold value is the maximum BD or CCE per span per cell (per span and per carrier) in the target subcarrier spacing, taking CCE as an example, that is, in Table 2 and / or the maximum BD or CCE per slot per cell in the target subcarrier spacing. Taking CCE as an example, it is the value in Table 1. Here, per means each, and cell means carrier.

[0056] In the embodiment of the present application, the second threshold value is the maximum BD or CCE per span in the target subcarrier spacing, taking CCE as an example, and / or the maximum BD or CCE per slot in the target subcarrier spacing, taking CCE as an example,

[0057] In the embodiment of the present application, the number of carriers supported by the terminal is reported by one of the following:

[0058] the number of supported carriers reported by the terminal when determining the second threshold value in the time slot;

[0059] the number of supported carriers reported by the terminal when determining the second threshold value in the time span;

[0060] When determining the second threshold value in the time span, the terminal reports the number of supported carriers respectively for different first parameters.

[0061] For example, the number of carriers supported reported by the terminal may be: the number of supported carriers reported by the terminal when determining the maximum BD or maximum CCE per slot in the target subcarrier spacing. Alternatively, the number of carriers supported reported by the terminal may also be: the number of supported carriers reported by the terminal when determining the maximum BD or maximum CCE per span in the target subcarrier spacing. Alternatively, the number of carriers supported reported by the terminal may also be: the number of supported carriers reported by the terminal for different Combinations (X, Y) when determining the maximum BD or maximum CCE per span in the target subcarrier spacing. It will be understood that there may be many ways to determine the number of carriers supported reported by the terminal, and it is not limited to the cases listed in the above examples.

[0062] For example, when determining the second threshold value in the time slot, the number of supported carriers reported by the terminal is calculated as follows: Indicates that the value range can be 4 to 16. Alternatively, when determining the second threshold value in the time span, the number of supported carriers reported by the terminal is expressed as Indicates that the value range can be an integer not less than 4. Alternatively, when determining the second threshold value in the time span, the number of supported carriers reported by the terminal for different first parameters is expressed as follows: Indicates that the value range can be an integer not less than 4.

[0063] It should be noted that before determining the first threshold, it is necessary to determine whether the primary carrier supports enhanced physical downlink control channel monitoring capability. Assuming that all primary carriers support enhanced physical downlink control channel monitoring capability, the first threshold can be the maximum BD or CCE per span per cell in the target subcarrier spacing.

[0064] In the case that at least one main carrier does not support enhanced physical downlink control channel monitoring capability, the first threshold value for the carrier that does not support enhanced physical downlink control channel monitoring capability is determined in the following manner: the first threshold value of the main carrier that does not support enhanced physical downlink control channel monitoring capability in the time slot is used as the first threshold value in the time span.

[0065] It should be noted that the physical downlink control channel monitoring capability enhancement is not supported, which means that the PDCCH monitoring capability in NR Rel-16 is not supported, or the maximum non-overlapping CCE value (or maximum BD value) determined per span is not supported, or the maximum non-overlapping CCE value (or maximum BD value) determined based on Combination (X, Y, μ) is not supported. It should be noted that the PDCCH monitoring capability is enhanced in NR Rel-16 (New Radio Release 16), and the maximum CCE (or maximum BD) per span per cell is defined, which is referred to as R16 capability. The current PDCCH monitoring capability in NR Rel-15 (New Radio Release 15) is the maximum CCE (or maximum BD) defined per slot per cell, as shown in Table 1, referred to as R15 capability.

[0066] In a case where at least one primary carrier does not support enhanced physical downlink control channel monitoring capability, determining the first threshold value for the carrier that supports enhanced physical downlink control channel monitoring capability by one of the following methods:

[0067] A first threshold value in a timeslot is used for a carrier supporting enhanced physical downlink control channel monitoring capability;

[0068] determining a first threshold value in a time slot based on the first threshold value in the time span and the number of non-empty time spans;

[0069] determining a first threshold value in a time slot based on the first threshold value in the time span and the number of time spans;

[0070] A first threshold value in a time slot is determined based on the first threshold value in the time span and a predetermined value.

[0071] It should be noted that in the step of using the first threshold value in the time slot for the carrier supporting enhanced physical downlink control channel monitoring capability, the threshold value is the maximum CCE value or maximum BD value per slot per cell in NR Rel-15, or the maximum CCE value or maximum BD value per slot per cell newly defined in Rel-16.

[0072] It should be noted that in the step of determining the first threshold value in the time slot based on the first threshold value in the time span and the predetermined value, a preset value is determined for each Combination (X, Y). For example, it is determined by C (X, Y, μ) × the predetermined value. Assuming that the preset values ​​are determined to be 7, 3, and 2 for Combination (2, 2, μ), Combination (4, 3, μ), and Combination (7, 3, μ), respectively, the first threshold values ​​in the time slot determined based on the first threshold value in the time span and the preset value are: and

[0073] It should be noted that, when at least one primary carrier does not support enhanced physical downlink control channel monitoring capability, the second threshold value is determined separately for the carrier that supports enhanced physical downlink control channel monitoring capability and the carrier that does not support enhanced physical downlink control channel monitoring capability. For example, for the primary carrier that supports enhanced physical downlink control channel monitoring capability, the second threshold value is calculated based on the number of carriers that meet the first setting condition, the total number of downlink carriers, the number of carriers supported by the terminal report, and the maximum BD or CCE per span per cell in the target subcarrier spacing. For the carrier that does not support enhanced physical downlink control channel monitoring capability, the second threshold value is calculated based on the number of carriers that meet the first setting condition, the total number of downlink carriers, the number of carriers supported by the terminal report, and the maximum BD or CCE per slot per cell in the target subcarrier spacing.

[0074] It should be noted that, when at least one primary carrier does not support enhanced physical downlink control channel monitoring capability, the total number of downlink carriers includes the total number of downlink carriers based on the time span, and the total number of downlink carriers based on the time span is determined in one of the following ways:

[0075] The total number of all modulated carriers corresponding to the active carrier that supports enhanced physical downlink control channel monitoring capabilities. In the present invention, all modulated carriers corresponding to the active carrier include the active carrier itself and all modulated carriers scheduled by the active carrier;

[0076] The sum of all modulated carriers corresponding to the active carriers that support enhanced physical downlink control channel monitoring capability, excluding the active carriers that are configured not to support enhanced physical downlink control channel monitoring capability;

[0077] The sum of all modulated carriers corresponding to the main modulated carrier that supports enhanced physical downlink control channel monitoring capability, excluding the main modulated carrier whose time span pattern has only one time span;

[0078] The sum of the number of all modulated carriers corresponding to the main modulated carrier that supports enhanced physical downlink control channel monitoring capability, but excluding the main modulated carrier that is not configured with the first downlink control information, where the first downlink control information is the DL DCI and UL DCI for scheduling unicast services newly defined by NR Rel-16, namely Rel-16new DCI, namely DCI Format 0_2 / 1_2.

[0079] The total number of all configured downlink carriers.

[0080] It should be noted that, when at least one primary carrier does not support enhanced physical downlink control channel monitoring capability, the total number of downlink carriers includes the total number of downlink carriers based on time slots, and the total number of downlink carriers based on time slots is determined in one of the following ways:

[0081] The total number of all configured downlink carriers;

[0082] The sum of the number of all modulated carriers corresponding to the main modulated carrier that does not support enhanced physical downlink control channel monitoring capability, wherein the meaning of all modulated carriers corresponding to the main modulated carrier has been explained in the embodiments of this application and will not be repeated here;

[0083] The sum of the number of all modulated carriers corresponding to the active carrier that does not support the enhanced physical downlink control channel monitoring capability, and the sum of the number of all modulated carriers corresponding to the active carrier that supports the enhanced physical downlink control channel monitoring capability and is configured not to support the enhanced physical downlink control channel monitoring capability;

[0084] The number of all modulated carriers corresponding to the main modulated carrier that does not support the enhanced physical downlink control channel monitoring capability, and the sum of the number of all modulated carriers corresponding to the main modulated carrier whose time span pattern has only one time span among the main modulated carriers that support the enhanced physical downlink control channel monitoring capability;

[0085] The number of all modulated carriers corresponding to the main modulated carrier that does not support the enhanced physical downlink control channel monitoring capability, and the sum of the number of all modulated carriers corresponding to the main modulated carrier among the main modulated carriers that support the enhanced physical downlink control channel monitoring capability and are not configured with the first downlink control information, where the meaning of the first downlink control information has been explained in the embodiments of the present application and will not be repeated here.

[0086] In an exemplary embodiment, for an R16 URLLC (Ultra-Reliable and Low Latency Communications) terminal (taking this as an example), the maximum number of blind decodes (BD threshold) and / or the maximum number of non-overlapping CCEs for channel estimation (CCE threshold, or maximum CCE) are increased relative to R15, and the BD threshold and / or CCE threshold are defined at the span granularity. The CCE threshold is used as an example for description below. Similarly, the BD threshold can also be defined using the following method.

[0087] In a carrier aggregation scenario, all the main carriers support enhanced PDCCH monitoring capabilities. The subcarrier spacing of the main carrier is the target subcarrier spacing and the number of carriers of the time span pattern, the total number of downlink carriers, the number of carriers supported by the terminal report, and the maximum CCE value per span per cell in the target subcarrier spacing are obtained based on the same first parameter. The second threshold value of the target subcarrier spacing in the time span is determined. In the carrier aggregation scenario, when all the main carriers support enhanced PDCCH monitoring capabilities, a solution is provided for determining the maximum number of candidate sets and the maximum number of non-overlapping CCEs for each subcarrier spacing in each time span to avoid exceeding the terminal detection capability.

[0088] In the embodiment of the present application, the total number of downlink carriers is the total number of all downlink carriers. Optionally, the total number of downlink carriers may also be the total number of carriers with fully or partially overlapping spans at the same time.

[0089] For example, it is assumed that each main modulation carrier obtains a time span pattern based on Combination (2, 2). Figure 2 A schematic diagram of a frame structure provided in an embodiment of the present application. Figure 2 As shown, CC#0 is cross-carrier scheduled to CC#0 to CC#3, and CC#4 and CC#5 are all same-carrier scheduled (also called self-carrier scheduling). At this time, it is assumed that all downlink carriers are the total number of downlink carriers, that is, The number of carriers supported by the terminal is Then, calculate the number of CCEs for each subcarrier spacing for each span, also known as the maximum value, by As shown in Table 3.

[0090] It should be noted that the embodiment of the present application takes the calculation of the maximum CCE value as an example, and the calculation of the maximum BD value is similar. No more examples.

[0091] Table 3 Maximum number of CCEs in each time span for different (X, Y) combinations

[0092]

[0093] For example, suppose Figure 2 All the main modulation carriers are scheduled on the same carrier, that is, CC#0 to CC#5 have no CIF (that is, CIF=0). At this time, the upper limit of the per span CCE of each subcarrier spacing is shown in Table 4.

[0094] Table 4 Maximum number of CCEs in each time span for different (X, Y) combinations

[0095]

[0096] In an exemplary embodiment, in a carrier aggregation scenario, some primary carriers support enhanced PDCCH monitoring capabilities, while some primary carriers do not. This embodiment uses the example of carriers with subcarrier spacing of 15 kHz and 30 kHz supporting enhanced PDCCH monitoring capabilities, while carriers with subcarrier spacing of 60 kHz and 120 kHz not supporting enhanced PDCCH monitoring capabilities, but is not limited thereto.

[0097] By determining the second threshold value of the target subcarrier spacing based on the number of carriers that meet the first setting condition, the total number of downlink carriers, the number of carriers supported by the terminal report, and the first threshold value, a scheme for determining the maximum number of candidate sets and the maximum number of non-overlapping CCEs for each subcarrier spacing in each time span is provided in a carrier aggregation scenario where some main carriers support enhanced PDCCH monitoring capabilities, thereby avoiding exceeding the terminal detection capability.

[0098] In this embodiment, for a primary carrier supporting enhanced PDCCH monitoring capability, the number of carriers that meet the first set condition is: the number of carriers that meet the conditions that the subcarrier spacing of the primary carrier is the target subcarrier spacing and the time span pattern is obtained based on the same first parameter. For a primary carrier that does not support enhanced PDCCH monitoring capability, the number of carriers that meet the first set condition is: the number of carriers that meet the conditions that the subcarrier spacing of the primary carrier is the target subcarrier spacing. For a primary carrier that does not support enhanced PDCCH monitoring capability, its first threshold value in the time slot is used as the first threshold value in the time span.

[0099] For example, when carriers with subcarrier spacing of 15 kHz and 30 kHz support enhanced PDCCH monitoring capability, the maximum CCE values ​​of different Combinations (X, Y) in 15 kHz and 30 kHz carriers are shown in Table 5. Note that the values ​​are not limited to those in Table 5.

[0100] Table 5 Maximum number of CCEs in each carrier for different (X, Y) combinations

[0101]

[0102] It is assumed that each primary carrier supporting enhanced PDCCH monitoring capability obtains a time span pattern based on Combination (2, 2). Figure 3 This is another frame structure diagram provided in the embodiment of the present application. Figure 3 As shown, CC#0 to CC#5 are all scheduled on the same carrier. For the main carrier that does not support the enhanced PDCCH monitoring capability, the first threshold value of the main carrier that does not support the enhanced physical downlink control channel monitoring capability in the time slot is used as the first threshold value in the time span. For example, the maximum BD or CCE of perslot per cell in the target subcarrier spacing, taking CCE as an example, is as shown in Table 1. When carriers with subcarrier spacing of 60 kHz and 120 kHz do not support enhanced PDCCH monitoring capability, one slot of 60 kHz and 120 kHz can be used as one span, and CCE_span(slot) can be used as CCE_span(X,Y).

[0103] At this time, it is assumed that all downlink carriers are the total number of downlink carriers, that is, The number of carriers supported by the terminal is The maximum number of CCEs for each subcarrier spacing in each span is As shown in Table 6.

[0104] Table 6 Maximum number of CCEs in each time span for different (X, Y) combinations

[0105]

[0106] In an exemplary embodiment, in a carrier aggregation scenario, some primary carriers support enhanced PDCCH monitoring capabilities, while some primary carriers do not. This embodiment uses the example of carriers with subcarrier spacing of 15 kHz and 30 kHz supporting enhanced PDCCH monitoring capabilities, while carriers with subcarrier spacing of 60 kHz and 120 kHz not supporting enhanced PDCCH monitoring capabilities, but is not limited thereto.

[0107] By determining the second threshold value of the target subcarrier spacing based on the number of carriers that meet the first setting condition, the total number of downlink carriers, the number of carriers supported by the terminal report, and the first threshold value, a scheme for determining the maximum number of candidate sets and the maximum number of non-overlapping CCEs for each subcarrier spacing in each time span is provided in a carrier aggregation scenario where some main carriers support enhanced PDCCH monitoring capabilities, thereby avoiding exceeding the terminal detection capability.

[0108] It should be noted that the method for determining the number of carriers that meet the first setting condition is the same as that in the above embodiment and will not be repeated here.

[0109] It should be noted that the method for determining the number of carriers supported by the terminal as reported is the same as that in the above embodiment, and will not be repeated here.

[0110] In this embodiment, for a primary carrier that does not support enhanced PDCCH monitoring capability, the total number of downlink carriers includes the total number of downlink carriers based on time slots, and the total number of downlink carriers based on time slots is determined by one of the following methods:

[0111] The total number of all configured downlink carriers;

[0112] The sum of all modulated carriers corresponding to the master carrier that does not support enhanced physical downlink control channel monitoring capability;

[0113] The sum of the number of all modulated carriers corresponding to the active carrier that does not support the enhanced physical downlink control channel monitoring capability, and the sum of the number of all modulated carriers corresponding to the active carrier that supports the enhanced physical downlink control channel monitoring capability and is configured not to support the enhanced physical downlink control channel monitoring capability;

[0114] The number of all modulated carriers corresponding to the main modulated carrier that does not support the enhanced physical downlink control channel monitoring capability, and the sum of the number of all modulated carriers corresponding to the main modulated carrier whose time span pattern has only one time span among the main modulated carriers that support the enhanced physical downlink control channel monitoring capability;

[0115] The number of all modulated carriers corresponding to the main modulated carrier that does not support the enhanced physical downlink control channel monitoring capability, and the sum of the number of all modulated carriers corresponding to the main modulated carrier that supports the enhanced physical downlink control channel monitoring capability and is not configured with the first downlink control information.

[0116] In this embodiment, for the primary carrier supporting enhanced PDCCH monitoring capability, the total number of downlink carriers includes the total number of downlink carriers based on the time span, and the total number of downlink carriers based on the time span is determined by one of the following methods:

[0117] The sum of all modulated carriers corresponding to the master carrier that supports enhanced physical downlink control channel monitoring capability;

[0118] The sum of all modulated carriers corresponding to the active carriers that support enhanced physical downlink control channel monitoring capability, excluding the active carriers that are configured not to support enhanced physical downlink control channel monitoring capability;

[0119] The sum of all modulated carriers corresponding to the main modulated carrier that supports enhanced physical downlink control channel monitoring capability, excluding the main modulated carrier whose time span pattern has only one time span;

[0120] The sum of the number of all modulated carriers corresponding to the active carrier supporting enhanced physical downlink control channel monitoring capability, excluding the active carrier not configured with the first downlink control information;

[0121] The total number of all configured downlink carriers.

[0122] It should be noted that for the main carrier that does not support enhanced PDCCH monitoring capability, any method of determining the total number of downlink carriers can be combined with any method of determining the total number of downlink carriers for the main carrier that supports enhanced PDCCH monitoring capability to determine the total number of downlink carriers.

[0123] In this embodiment, for the main carrier supporting enhanced PDCCH monitoring capability, the first threshold value is determined by one of the following methods (i.e., converting the span-based PDCCH monitoring capability to the slot-based PDCCH monitoring capability, the conversion method is one of the following): using the first threshold value in the time slot for the carrier supporting enhanced physical downlink control channel monitoring capability; or, determining the first threshold value in the time slot based on the first threshold value in the time span and the number of non-empty time spans; or, determining the first threshold value in the time slot based on the first threshold value in the time span and the number of time spans; or, determining the first threshold value in the time slot based on the first threshold value in the time span and the number of time spans. Or, determining the first threshold value in the time slot based on the first threshold value in the time span and a predetermined value.

[0124] For example, for a primary carrier supporting enhanced PDCCH monitoring capability, the first threshold value uses a threshold value in a time slot.

[0125] At this time, it is assumed that all downlink carriers are the total number of downlink carriers, that is, The number of carriers supported by the terminal is The maximum number of CCEs for each subcarrier spacing in each slot is As shown in Table 7.

[0126] Table 7 Maximum number of CCEs in each slot

[0127]

[0128] For example, for a primary carrier supporting enhanced PDCCH monitoring capability, the first threshold value in the time slot is determined based on the first threshold value in the time span and the number of non-empty time spans. The number of non-empty time spans is not greater than the number of time spans in the time span pattern. At this time, it is assumed that each primary carrier supporting enhanced PDCCH monitoring capability obtains a time span pattern based on Combination (2, 2), such as Figure 3 Assume Figure 3 In the time span pattern of CC#0, the number of non-empty time spans in the current time slot is 5, which is converted to 16*5=80; the number of non-empty time spans in the time span pattern of CC#1 is 4, which is converted to 16*4=64; the number of non-empty time spans in the time span pattern of CC#4 is 4, which is converted to 16*4=64; the number of non-empty time spans in the time span pattern of CC#5 is 4, which is converted to 16*4=64. It should be noted that the second threshold value is calculated by adding the first threshold values ​​of different main modulation carriers with the same subcarrier spacing.

[0129] Assume that all downlink carriers are the total number of downlink carriers, that is The number of carriers supported by the terminal is The maximum number of CCEs for each slot for each subcarrier spacing / target subcarrier spacing is shown in Table 8.

[0130] Table 8 Maximum number of CCEs in each slot

[0131]

[0132] For example, for the primary carrier supporting the enhanced PDCCH monitoring capability, the first threshold value in the time slot is determined according to the first threshold value in the time span and the number of time spans. At this time, it is assumed that each primary carrier supporting the enhanced PDCCH monitoring capability obtains a time span pattern based on Combination (2, 2), such as Figure 3 Assume Figure 3 In the example, the time span pattern of CC#0 has 7 time spans, which is 16*7=112 after conversion; the time span pattern of CC#1 has 5 time spans, which is 16*5=80 after conversion; the time span pattern of CC#4 has 5 time spans, which is 16*5=80 after conversion; and the time span pattern of CC#5 has 5 time spans, which is 16*5=80 after conversion. It should be noted that the second threshold is calculated by adding the first threshold values ​​of different main modulation carriers with the same subcarrier spacing.

[0133] Assume that all downlink carriers are the total number of downlink carriers, that is The number of carriers supported by the terminal is The maximum number of CCEs for each subcarrier spacing in each slot is shown in Table 9.

[0134] Table 9 Maximum number of CCEs in each slot

[0135]

[0136] For example, for the main carrier supporting enhanced PDCCH monitoring capability, the first threshold value in the time slot is determined based on the first threshold value in the time span and the predetermined value. Assume that each main carrier supporting enhanced PDCCH monitoring capability obtains a time span pattern based on Combination(2,2). At this time, the preset value for Combination(2,2) is determined to be 7, then for CC#0, the first threshold value is 16*7=112, for CC#1, the first threshold value is 16*7=112, for CC#4, the first threshold value is 16*7=112, and for CC#5, the first threshold value is 16*7=112. It should be noted that the first threshold values ​​of different main carriers with the same subcarrier spacing are added together to calculate the second threshold value.

[0137] Assume that all downlink carriers are the total number of downlink carriers, that is The number of carriers supported by the terminal is The maximum number of CCEs for each subcarrier spacing in each slot is shown in Table 10.

[0138] Table 10 Maximum number of CCEs in each slot

[0139]

[0140] In an exemplary embodiment, in a carrier aggregation scenario, some primary carriers support enhanced PDCCH monitoring capabilities, while some primary carriers do not. This embodiment uses the example of carriers with subcarrier spacing of 15 kHz and 30 kHz supporting enhanced PDCCH monitoring capabilities, while carriers with subcarrier spacing of 60 kHz and 120 kHz do not support enhanced PDCCH monitoring capabilities, but is not limited thereto. For another example, for one or a group of carriers, the base station configures it to support enhanced PDCCH monitoring capabilities or not support enhanced PDCCH monitoring capabilities.

[0141] In the case that at least one main modulation carrier does not support the enhanced physical downlink control channel monitoring capability, by determining the second threshold value respectively for the carrier that supports the enhanced physical downlink control channel monitoring capability and the carrier that does not support the enhanced physical downlink control channel monitoring capability, in the carrier aggregation scenario, when some main modulation carriers support the enhanced PDCCH monitoring capability, a solution is provided for determining the maximum number of candidate sets and the maximum number of non-overlapping CCEs for each subcarrier interval in each time span to avoid exceeding the terminal detection capability.

[0142] It should be noted that the method for determining the total number of downlink carriers is the same as that in the above embodiment, the method for determining the number of carriers that meet the first setting condition is the same as that in the above embodiment, and the method for determining the number of carriers supported by the terminal report is the same as that in the above embodiment, and will not be repeated here.

[0143] It should be noted that for a primary carrier that does not support enhanced PDCCH monitoring capability, the threshold value in the timeslot is used as the first threshold value (for example, obtained according to Table 1). For a primary carrier that supports enhanced PDCCH monitoring capability, the threshold value in the time span is used as the first threshold value (for example, obtained according to Table 5).

[0144] It is assumed that each primary carrier supporting enhanced PDCCH monitoring capability obtains a time span pattern based on Combination (2, 2). Figure 4 This is another frame structure diagram provided in the embodiment of the present application. Figure 4 As shown, CC#0 to CC#9 are all scheduled on the same carrier. Assuming the total number of downlink carriers based on time slots Total number of downlink carriers based on time span The number of carriers supported by the terminal is Then, the number of CCEs for each subcarrier spacing in each time span is calculated as shown in Table 11, and the number of CCEs for each subcarrier spacing in each time slot is calculated as shown in Table 12.

[0146]

[0147] Table 12 Maximum number of CCEs in each time slot

[0148]

[0149] It should be noted that in Figures 2 to 4 In the IEEE Spectrum ...

[0150] Currently, the PDCCH monitoring capability in NR Rel-15 (New Radio Release 15) is the maximum BD (or maximum CCE) defined per slot per cell, referred to as R15 capability. In NR Rel-16 (New Radio Release 16), the PDCCH monitoring capability is enhanced, and the maximum CCE (or maximum BD) per span per cell is defined, referred to as R16 capability. However, the relevant technology does not provide a method for using R15 and R16 capabilities. One possible method is to use R15 capabilities for eMBB (enhanced Mobile Broadband) services and R16 capabilities for URLLC services; another possible method is to configure the terminal to use R15 capabilities or R16 capabilities without distinguishing between service types. The above method 1 limits R16 to only one service type, while the method 2 cannot have both R15 and R16 capabilities at the same time, and both have certain limitations.

[0151] In view of the above problems, an embodiment of the present application proposes a method for using threshold values, including: determining a method for using different threshold values ​​according to one of the following methods:

[0152] Different downlink control information formats use different threshold values;

[0153] Different search spaces use different threshold values;

[0154] Different search space sets are configured for the same threshold value, and different sub-threshold values ​​are configured for each search space set.

[0155] In this embodiment, different threshold values ​​are used for different downlink control information formats, including:

[0156] Get downlink control information format;

[0157] determining a threshold value to be used according to the downlink control information format;

[0158] The threshold value includes a first threshold value based on a time slot and a second threshold value based on a time span.

[0159] This embodiment provides a method for using a threshold value, which can enable the enhanced PDCCH monitoring capability to be applied to the scheduling of various service types, thereby achieving flexible use of the enhanced PDCCH monitoring capability.

[0160] For example, R15 downlink control information uses R15 capabilities, while R16 downlink control information uses R16 capabilities. R16 downlink control information uses a new downlink control information (DCI) format introduced in NR Release 16 (specifically, one DCI format for scheduling uplink traffic channels and one DCI format for scheduling downlink traffic channels). It is used to schedule R16 URLLC services and can also schedule eMBB services. In this case, R16 capabilities are bound to R16 DCI, enabling scheduling of both eMBB and URLLC services.

[0161] In this embodiment, different search space sets are configured for the same threshold value, and different sub-threshold values ​​are configured for different search space sets, including:

[0162] In case of configuring a second threshold value based on a time span, configuring at least two groups of search space sets;

[0163] The sub-threshold values ​​corresponding to the respective search space sets are determined respectively, and preferably the sub-threshold values ​​corresponding to the respective search space sets are distinguished by high-level configuration or pre-definition.

[0164] For example, when configured as R16 capability, X groups of search space sets are configured, and the second threshold value C_x corresponding to each group of search space sets is determined separately, where x = 0, 1, ..., X-1. The sum of the second threshold values ​​corresponding to each group is the R16 capability. Preferably, X = 2. In this case, the two groups of corresponding second threshold values ​​C_0 and C_1 are used for eMBB and URLLC, or for eMBB and eMBB / URLLC, or for R15 DCI and R16 DCI, or for R15 DCI and R15 DCI / R16 DCI, respectively. Among them, eMBB / URLLC represents eMBB and URLLC, and R15 DCI / R16 DCI represents R15 DCI and R16 DCI.

[0165] In this embodiment, different search spaces use different threshold values, including:

[0166] Get the configuration information of the search space;

[0167] determining a threshold value to be used according to the configuration information;

[0168] The threshold value includes a first threshold value based on a time slot and a second threshold value based on a time span.

[0169] It should be noted that determining the threshold value to be used according to the configuration information includes:

[0170] In a case where the first downlink control information and the second downlink control information are configured in the same search space, the threshold to be used is determined according to the priority or service type indicated in the first downlink control information.

[0171] Optionally, the first downlink control information may be the DL DCI and UL DCI for scheduling unicast services newly defined by NR Rel-16, i.e., Rel-16new DCI, i.e., DCI Format 0_2 / 1_2. The second downlink control information may be the DL DCI and UL DCI for scheduling unicast services already defined by NR Rel-15, i.e., Rel-15non-fallback DCI, i.e., DCI Format 0_1 / 1_1.

[0172] For example, if the first downlink control information indicates that the service type is URLLC (or high priority), the threshold value to be used is the second threshold value based on the time span.

[0173] It should be noted that, when the first downlink control information and the second downlink control information are not detected, the method further includes:

[0174] Arbitrarily select a threshold value as the threshold value to be used;

[0175] Alternatively, a threshold value is arbitrarily selected as the threshold value to be used, and when the used resources or the number of detection times exceeds the threshold value to be used, the remaining threshold value is used as the threshold value to be used;

[0176] Alternatively, the sum of all threshold values ​​is calculated, and the calculated result is used as the threshold value to be used.

[0177] In this embodiment, determining the threshold value to be used according to the configuration information includes:

[0178] When the first downlink control information and the second downlink control information are configured in the same search space, a second threshold value based on a time span to be used is determined according to the first downlink control information, and a first threshold value based on a time slot to be used is determined according to the second downlink control information.

[0179] It should be noted that, when the first downlink control information and the second downlink control information are not detected, the method for determining the threshold to be used is the same as that in the above embodiment, and will not be described in detail here.

[0180] In this embodiment, acquiring configuration information of the search space includes: configuring a candidate set and a starting control channel element for the first downlink control information and the second downlink control information in the search space respectively, and using the candidate set and the starting control channel element as configuration information.

[0181] By adopting the above solution, when the first downlink control information and the second downlink control information are configured in the same search space, the R15 capability and the R16 capability can be distinguished, so that both the enhanced PDCCH monitoring capability and the R15 PDCCH monitoring capability can be fully utilized, thereby improving scheduling flexibility.

[0182] The above embodiment records that the (X, Y) set of terminal-reported candidates may include at least one of the following: {(7, 3), (4, 3) and (7, 3), (2, 2), (4, 3) and (7, 3)}. The time span pattern (span pattern) in the time slot is determined by the (X, Y) set of terminal-reported candidates, the PDCCH CORESET and the search space. The number of spans does not exceed floor (14 / X), where X is the minimum X in the Combination (X, Y) reported by the terminal. Since the minimum X = 2, the number of spans does not exceed 7. When the number of monitoring opportunities (MO) corresponding to the allocated search space (SS, search space) is greater than 7, the obtained span will be invalid. Therefore, the terminal needs to discard / not detect some monitoring opportunities so that the number of monitoring opportunities is no more than 7. However, how to determine the monitoring opportunities to be discarded is an urgent problem to be solved.

[0183] In view of this, an embodiment of the present application provides an information adjustment method, including:

[0184] When the number of monitoring opportunities corresponding to the search space exceeds a set threshold, monitoring opportunities that meet the set conditions are discarded.

[0185] Through the solution of this embodiment, span is effectively allocated, so that the enhanced PDCCH monitoring capability can be used and scheduling flexibility is improved.

[0186] It should be noted that the setting conditions include one of the following:

[0187] Discard based on the order of search space index;

[0188] Dropping based on the length order of the control resource set corresponding to the search space or monitoring opportunity;

[0189] The discarding is performed based on the order of the number of monitoring opportunities corresponding to the search space.

[0190] In an exemplary embodiment, when the number of monitoring opportunities corresponding to the search space exceeds a set threshold, the monitoring opportunities are discarded based on the order of the search space index. This can be specifically optimized to when the number of monitoring opportunities corresponding to the search space exceeds a set threshold, the monitoring opportunities are discarded from large to small based on the order of the search space index until the number of monitoring opportunities is no more than 7.

[0191] Figure 5 This is a schematic diagram of an original monitoring timing configuration provided by an embodiment of the present application. Figure 5As shown, the number of configured monitoring opportunities is 8, which exceeds 7. The number in the diagonal background in the figure represents the search space index. In an exemplary embodiment, when the number of monitoring opportunities corresponding to the search space exceeds a set threshold, the control resource sets corresponding to the search space or monitoring opportunities are discarded based on the length order. This can be specifically optimized to, when the number of monitoring opportunities corresponding to the search space exceeds a set threshold, discard them from large to small based on the length order of the control resource sets corresponding to the search space until the number of monitoring opportunities is no more than 7, or discard them from large to small based on the length order of the control resource sets corresponding to the monitoring opportunities until the number of monitoring opportunities is no more than 7. Figure 6 This is another schematic diagram of monitoring timing configuration after discarding processing provided by the embodiment of the present application. Figure 6 As shown, the monitoring opportunities of the control resource set corresponding to the search space with a length of 2 symbols are discarded, ensuring that the number of monitoring opportunities does not exceed 7, making the span allocation effective.

[0192] In an exemplary embodiment, when the number of monitoring opportunities corresponding to the search space exceeds a set threshold, the monitoring opportunities are discarded based on the order of the number of monitoring opportunities corresponding to the search space. This can be specifically optimized to, when the number of monitoring opportunities corresponding to the search space exceeds a set threshold, discard the monitoring opportunities from large to small based on the number of monitoring opportunities corresponding to the search space until the number of monitoring opportunities is no more than 7.

[0193] Optionally, for a search space having multiple monitoring opportunities, the order of discarding the monitoring opportunities includes: discarding from large to small, or discarding from small to large according to the OFDM symbol index; or, discarding the monitoring opportunities adjacent to the monitoring opportunities with a larger CORESET duration first.

[0194] Figure 7 This is another schematic diagram of the original monitoring timing configuration provided by the embodiment of the present application. Figure 7 As shown in Figure 1, the number of configured MOs is 8, which exceeds 7. The numbers on the diagonal background in the figure represent the search space index. Figure 8 This is another schematic diagram of monitoring timing configuration after discarding processing provided by the embodiment of the present application. Figure 8 As shown, the monitoring opportunities in the search space with 5 monitoring opportunities are discarded to ensure that the number of monitoring opportunities does not exceed 7, making the span allocation effective.

[0195] Currently, the granularity of enhanced frequency domain resource allocation type 1 (FDRA type 1, continuous resource allocation mode) is configured by radio resource control (RRC) parameters. Optionally, the configuration value is an integer number of RBs (Resource Blocks), for example, 1, 2, 4, 8, or 16 RBs. The granularity is the same as the starting point granularity and length indicator granularity. However, in actual applications, the RRC parameters may not be configured, resulting in improper reception of service channels.

[0196] In view of this, an embodiment of the present application provides an information adjustment method, including:

[0197] In the case that the granularity configuration parameter of the enhanced frequency domain resource allocation type 1 is not configured, a default value of the granularity configuration parameter is determined to be 1 RB or 1 RBG (Resource Block Group).

[0198] For example, when RRC parameters are not configured, you can determine the RRC parameters in one of the following ways:

[0199] The default value of the granularity configuration parameter is determined to be 1 RB, which is the same as the Rel-15 FDRA type 1 granularity by default;

[0200] The default value of the granularity configuration parameter is determined to be 1 RBG (when RBG is configured). The RBG size is the resource block size configured for FDRAType0. That is, the default is the same as the RBG granularity in the system.

[0201] When RBG is configured, the default value is 1RBG. When RBG is not configured, the default value is 1RB.

[0202] The solution provided in this embodiment ensures that when the RRC parameters are not configured, accurate values ​​can be obtained, thereby avoiding inconsistent understanding between the terminal and the base station and ensuring correct reception of the service channel.

[0203] Figure 9 This is a schematic diagram of the structure of an information determination device provided in an embodiment of the present application. The device avoids exceeding the terminal detection capability by executing the information determination method. Figure 9 As shown, the information determination device in the embodiment of the present application includes:

[0204] An acquisition module 910 is configured to acquire the number of carriers that meet a first setting condition, the total number of downlink carriers, the number of carriers supported by the terminal as reported, and a first threshold value;

[0205] The threshold value determination module 920 is configured to determine a second threshold value of the target subcarrier spacing according to the number of carriers meeting the first setting condition, the total number of downlink carriers, the number of carriers supported by the terminal as reported, and the first threshold value.

[0206] The information determination device provided in the embodiment of the present application is configured to implement the information determination method of the above embodiment. The implementation principle and technical effect of the information determination device are similar to those of the information determination method, and will not be repeated here.

[0207] In one embodiment, the first setting condition includes at least one of the following:

[0208] The subcarrier spacing of the main modulated carrier is the target subcarrier spacing;

[0209] The subcarrier spacing of the primary carrier is the target subcarrier spacing and the time span pattern is obtained based on the same first parameter.

[0210] In one example, the number of carriers supported by the terminal is reported as one of the following:

[0211] the number of supported carriers reported by the terminal when determining the second threshold value in the time slot;

[0212] the number of supported carriers reported by the terminal when determining the second threshold value in the time span;

[0213] When determining the second threshold value in the time span, the terminal reports the number of supported carriers respectively for different first parameters.

[0214] In one example, when at least one primary carrier does not support enhanced physical downlink control channel monitoring capability, the first threshold value is determined for the carrier that does not support enhanced physical downlink control channel monitoring capability in the following manner:

[0215] The first threshold value of the main modulation carrier that does not support the enhanced physical downlink control channel monitoring capability in the time slot is used as the first threshold value in the time span.

[0216] In one example, when at least one primary carrier does not support enhanced physical downlink control channel monitoring capability, the first threshold value is determined for the carrier that supports enhanced physical downlink control channel monitoring capability in one of the following ways:

[0217] A first threshold value in a timeslot is used for a carrier supporting enhanced physical downlink control channel monitoring capability;

[0218] determining a first threshold value in a time slot based on the first threshold value in the time span and the number of non-empty time spans;

[0219] determining a first threshold value in a time slot based on the first threshold value in the time span and the number of time spans;

[0220] A first threshold value in a time slot is determined based on the first threshold value in the time span and a predetermined value.

[0221] In one example, when at least one primary carrier does not support enhanced physical downlink control channel monitoring capability, the second threshold value is determined separately for carriers that support enhanced physical downlink control channel monitoring capability and carriers that do not support enhanced physical downlink control channel monitoring capability.

[0222] In one example, the total number of downlink carriers includes the total number of downlink carriers based on a time span, and the total number of downlink carriers based on the time span is determined by one of the following methods:

[0223] The sum of all modulated carriers corresponding to the master carrier that supports enhanced physical downlink control channel monitoring capability;

[0224] The sum of all modulated carriers corresponding to the active carriers that support enhanced physical downlink control channel monitoring capability, excluding the active carriers that are configured not to support enhanced physical downlink control channel monitoring capability;

[0225] The sum of all modulated carriers corresponding to the main modulated carrier that supports enhanced physical downlink control channel monitoring capability, excluding the main modulated carrier whose time span pattern has only one time span;

[0226] The sum of the number of all modulated carriers corresponding to the active carrier supporting enhanced physical downlink control channel monitoring capability, excluding the active carrier not configured with the first downlink control information;

[0227] The total number of all configured downlink carriers.

[0228] In one example, the total number of downlink carriers includes the total number of downlink carriers based on time slots, and the total number of downlink carriers based on time slots is determined by one of the following methods:

[0229] The total number of all configured downlink carriers;

[0230] The sum of all modulated carriers corresponding to the master carrier that does not support enhanced physical downlink control channel monitoring capability;

[0231] The sum of the number of all modulated carriers corresponding to the active carrier that does not support the enhanced physical downlink control channel monitoring capability, and the sum of the number of all modulated carriers corresponding to the active carrier that supports the enhanced physical downlink control channel monitoring capability and is configured not to support the enhanced physical downlink control channel monitoring capability;

[0232] The number of all modulated carriers corresponding to the main modulated carrier that does not support the enhanced physical downlink control channel monitoring capability, and the sum of the number of all modulated carriers corresponding to the main modulated carrier whose time span pattern has only one time span among the main modulated carriers that support the enhanced physical downlink control channel monitoring capability;

[0233] The number of all modulated carriers corresponding to the main modulated carrier that does not support the enhanced physical downlink control channel monitoring capability, and the sum of the number of all modulated carriers corresponding to the main modulated carrier that supports the enhanced physical downlink control channel monitoring capability and is not configured with the first downlink control information.

[0234] The embodiment of the present application further provides a threshold value using device, including: a method for determining the use of different threshold values ​​according to one of the following methods:

[0235] Different downlink control information formats use different threshold values;

[0236] Different search spaces use different threshold values;

The implementation principle and technical effect of the threshold using device are similar to those of the threshold using method, and will not be repeated here.

[0256] Alternatively, a threshold value is arbitrarily selected as the threshold value to be used, and when the used resources or the number of detection times exceeds the threshold value to be used, the remaining threshold value is used as the threshold value to be used;

[0257] Alternatively, the sum of all threshold values ​​is calculated, and the calculated result is used as the threshold value to be used.

[0258] In one example, obtaining configuration information of the search space includes:
