This application claims priority of PRC Patent Application No. 201910944446.2 filed with the State Intellectual Property Office of the People's Republic of China (CNIPA) on September 30, 2019, the contents of which are hereby incorporated by reference in their entirety.

FIELD OF TECHNOLOGY

The present application relates to the field of communication and, for example, to a method and device for determining information, a terminal and a data carrier.

BACKGROUND OF THE INVENTION

4th generation (4G) mobile communication technology, Long Term Evolution (LTE)/Advanced Long Term Evolution (LTE-Advance/LTE-A), and 5th generation (5G) mobile communication technology are facing all increasing demands. In terms of development trend, 4G and 5G system designs have characteristics that support advanced mobile broadband network, ultra-reliable low latency transmission, and mass connectivity.

To support low latency ultra-reliable transmission characteristics, transmission must be performed with a short transmission time interval and a low bit rate, where the short transmission time interval may be a single Orthogonal Frequency Division Multiplexing (OFDM) symbol or multiple symbols. For the Physical Downlink Control Channel (PDCCH), transmission opportunities can be provided at several possible positions in an interval to reduce latency after data arrives, thereby enabling low latency transmission and providing high transmission reliability through a high level of aggregation. In the cell aggregation system, the maximum number of PDCCH discovery candidate sets to be supported by the terminal and the maximum number of non-overlapping control channel elements (CCEs) to be supported by the terminal are determined in each slot for each type of subcarrier spacing. However, when the improved PDCCH monitoring capability of the terminal is implemented, no efficient way is proposed in the cell aggregation scenario to determine the second threshold of each type of subcarrier spacing on each band.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention are described hereinafter in conjunction with the drawings. It should be noted that, unless in conflict, the embodiments described herein and their features may be combined with each other.

In the new radio (NR) system, the maximum number of PDCCH discovery candidate sets to be supported by the terminal and the maximum number of non-overlapping CCEs to be supported by the terminal are defined in each slot for each type of subcarrier spacing as shown in Table 1, where μ, which is 0, 1, 2, and 3 denotes the subcarrier spacing of 15 kHz, 30 kHz, 60 kHz, and 120 kHz, respectively. For convenience of description, "the maximum number of PDCCH detection candidate sets (also referred to as the maximum number of blind decoding events)" is referred to as the "maximum BD", and the "maximum number of non-overlapping CCEs" is referred to as the "maximum CCE value".

Если терминал сконфигурирован с

сотами нисходящей линии связи, когда

, максимальное количество кандидатных наборов для обнаружения PDCCH в каждом интервале для каждого типа разноса поднесущих составляет

, а максимальное количество неперекрывающихся ССЕ в каждом интервале для каждого типа разноса поднесущих составляет

, соответственно. Когда реализована улучшенная способность терминала к текущему контролю PDCCH, определяют максимальное количество неперекрывающихся ССЕ и максимальное количество кандидатных наборов для обнаружения PDCCH каждого диапазона. В сценарии агрегирования сот, когда принято ограничение поддерживающей способности терминала сообщать количество сот, на известном техники не предлагается никакого эффективного пути определения максимального количества неперекрывающихся ССЕ и максимального количества кандидатных наборов для обнаружения PDCCH на каждом диапазоне для каждого типа разноса поднесущих.In a cell aggregation system, the maximum number of PDCCH discovery candidate sets to be supported by the terminal and the maximum number of non-overlapping CCEs to be supported by the terminal do not always increase linearly with the number of aggregated cells, but are limited by the terminal's ability to report the number of cells.

If the terminal is configured with

downlink cells when

, the maximum number of PDCCH detection candidate sets in each slot for each subcarrier spacing type is

, and the maximum number of non-overlapping CCEs in each slot for each type of subcarrier spacing is

, respectively. When the improved PDCCH monitoring capability of the terminal is implemented, the maximum number of non-overlapping CCEs and the maximum number of candidate sets for PDCCH detection of each band are determined. In the cell aggregation scenario, when limiting the supporting ability of the terminal to report the number of cells is accepted, no efficient way is proposed in the art to determine the maximum number of non-overlapping CCEs and the maximum number of candidate sets for PDCCH detection on each band for each type of subcarrier spacing.

In embodiments of the present application, a method for determining information for solving the above tasks is provided.

In FIG. 1 is a flowchart of a method for determining information according to one embodiment of the present application. The method may be performed by an information determination device. The information determination device may be implemented in software and/or hardware. As shown in FIG. 1, the method includes steps S110 and S120.

In step S110, the number of cells satisfying the first predetermined condition, the total number of downlink cells, the number of supported cells reported by the terminal, and the first threshold value are obtained.

In step S120, the second target subcarrier spacing threshold is determined according to the number of cells satisfying the first predetermined condition, the total number of downlink cells, the number of supported cells reported by the terminal, and the first threshold.

The first predetermined condition includes at least one of the following: the subcarrier spacing of the scheduling cell is the target subcarrier spacing; or the subcarrier spacing of the scheduling cell is the target subcarrier spacing, and the banding scheme is obtained based on the same first parameter.

The target subcarrier spacing may be any one or more of the subcarrier spacing values defined by the protocol. For example, the subcarrier spacing is represented using μ, and different values of the subcarrier spacing can be distinguished by the value of μ. For example, in Table 1, μ, which is 0, 1, 2, and 3, represents the subcarrier spacing of 15 kHz, 30 kHz, 60 kHz, and 120 kHz, respectively.

The first parameter is a candidate combination (X, Y) reported by the terminal, and the first parameter may be expressed as a combination (X, Y). For example, a range scheme in an interval is determined by a candidate set (X, Y) reported by the terminal and a PDCCH control resource set (CORESET) as well as a search space. There is no overlap between ranges, and the gap between the beginnings of two ranges is at least X characters. The range duration is the maximum (maximum duration configured by CORESET, minimum Y reported by the terminal), and only the last range in the range scheme can have a shorter duration. The number of ranges does not exceed the result of the operation floor (14/X), where X is the minimum X in the combinations (X, Y) reported by the terminal. Optionally, the combination (X, Y) contains at least one of: (1, 1), (2, 1), (2, 2), (4, 1), (4, 2), (4, 3), (7, 1), (7, 2) or (7, 3). Optionally, the candidate set (X, Y) reported by the terminal contains at least one of: {(7, 3)}, {(4, 3), (7, 3)}, or {(2, 2), (4 , 3), (7, 3)}.

Taking as an example the maximum number of non-overlapping CCEs when the improved PDCCH monitoring capability of the terminal is implemented, the maximum number of non-overlapping CCEs of each band is determined, as shown in FIG. 2.

For example, assuming that the target subcarrier spacing is 60 kHz, the number of cells that satisfy the first given condition may be the sum of all scheduling cells that have a subcarrier spacing of 60 kHz. In yet another example, assuming that the target subcarrier spacing is 15 kHz and the scheduling cells divide the band patterns according to (X, Y)=(2, 2) and (X, Y)=(4, 3) respectively, the number of cells satisfying the first predetermined condition may include: the sum of all scheduling cells where the band scheme is divided based on (X, Y)=(2, 2) and all scheduling cells whose subcarrier spacing is 15 kHz, and the sum of all scheduling cells where the band scheme is divided based on (X, Y)=(4, 3), and all scheduling cells whose subcarrier spacing is 15 kHz.

.In this embodiment of the present application, the second threshold is the maximum BD value or the maximum CCE per band in the case where the subcarrier spacing is the target subcarrier spacing, and for example, when the second threshold is the maximum CCE per band in the case when the subcarrier spacing is the target subcarrier spacing as an example, the second threshold is

; and/or the second threshold is the maximum BD value or the maximum CCE per interval in the case where the subcarrier spacing is the target subcarrier spacing, and, for example, when the second threshold is the maximum CCE per interval in the case where the subcarrier spacing is is the target subcarrier spacing as an example, the second threshold is

.

In this embodiment of the present application, the number of supported cells reported by the terminal includes one of the following: in the case of determining the second threshold value in the interval, the number of supported cells reported by the terminal; in the case of determining the second threshold value in the range, the number of supported cells reported by the terminal; or, in the case of determining a second threshold value in the range, the number of supported cells reported by the terminal for different first parameters, respectively.

For example, the number of supported cells reported by the terminal may be the number of supported cells reported by the terminal when the maximum BD value or the maximum CCE value per interval is determined in the case where the subcarrier spacing is the target subcarrier spacing. Alternatively, the number of supported cells reported by the terminal may also be the number of supported cells reported by the terminal when the maximum BD value or the maximum CCE value per range is determined in the case where the subcarrier spacing is the target subcarrier spacing. Alternatively, the number of supported cells reported by the terminal may also be the numbers of supported cells reported by the terminal for different combinations of (X,Y) when determining the maximum BD value or the maximum CCE value per range in the case where the subcarrier spacing is the target subcarrier spacing . There may be many methods for determining the number of supported cells reported by the terminal, and these methods are not limited to the cases described in the examples above.

, the value of which can be from 4 to 16. Alternatively, in the case of determining the second threshold value in the range, the number of supported cells reported by the terminal is represented as

, the value range of which can be an integer of at least 4. Alternatively, in the case of determining the second threshold value in the range of the number of supported cells, reported by the terminal, for different first parameters, is presented as

, whose range of values can be an integer of at least 4.

Before determining the first threshold, it is necessary to determine if the scheduling cells support improved monitoring capability of the downlink physical control channel. Assuming that all scheduling cells support enhanced monitoring capability of the downlink physical control channel, the first threshold may be a maximum BD value or a maximum CCE value per band per cell in the case where the subcarrier spacing is the target subcarrier spacing.

In the case where at least one scheduling cell does not support the enhanced monitoring capability of the physical downlink control channel, the first threshold value for the cell that does not support the enhanced monitoring capability of the physical downlink control channel is determined as follows: the first a threshold value of at least one scheduling cell that does not support enhanced monitoring capability of a downlink physical control channel is determined as a first threshold value in the range.

The statement that the improved monitoring capability of the physical downlink control channel is not supported means that the monitoring capability of the PDCCH in the 16th release of the new radio (NR Rel-16) is not supported, or that the maximum value of non-overlapping CCEs (or the maximum BD value) defined per range is not supported, or that the maximum non-overlapping CCE value (or maximum BD value) determined based on the combination of (X, Y, μ) is not supported. In NR Rel-16, the PDCCH monitoring capability is improved and a maximum CCE value (or maximum BD value) per band per cell is defined, which is called R16 capability. In the 15th release of the new radio (NR Rel-15), the PDCCH monitoring capability is the maximum CCE value (or maximum BD value) defined per slot per cell as shown in Table 1, which is called R15 capability.

In the case where at least one scheduling cell does not support the enhanced monitoring capability of the physical downlink control channel, the first threshold for the cell that supports the enhanced monitoring capability of the physical downlink control channel is determined by one of the following methods: the first threshold in the interval is used for a cell that supports improved monitoring capability of the downlink physical control channel; the first threshold value in the interval is determined according to the first threshold value in the range and the number of non-empty ranges; the first threshold value in the interval is determined according to the first threshold value in the range and the number of ranges; or the first threshold value in the interval is determined according to the first threshold value in the range and the preset value.

When the first threshold in an interval is used for a cell that supports enhanced monitoring capability of the physical downlink control channel, the threshold is the maximum CCE value or maximum BD value per interval per cell in NR Rel-15 or the maximum CCE value or maximum the BD value per interval per cell, newly defined in Rel-16.

и

соответственно.When the first threshold value in the range is determined according to the first threshold value in the range and the preset value, the preset value is determined for combinations of (X, Y), respectively. For example, the first threshold value in the interval is determined by C(X, Y, μ)×preset value. Assuming that the preset values for combination (2, 2, μ), combination (4, 3, μ), and combination (7, 3, μ) are defined as 7, 3, and 2 respectively, the first threshold value in the interval, determined by according to the first threshold value in the range and the preset value, is

,

And

respectively.

In the case where at least one scheduling cell does not support the enhanced monitoring capability of the physical downlink control channel, a second threshold is determined for a cell that supports the improved monitoring capability of the physical downlink control channel, and the second threshold is determined for a cell that does not support enhanced monitoring capability of the physical downlink control channel, respectively. For example, for scheduling cells that support enhanced monitoring capability of the downlink physical control channel, the second threshold is determined according to the number of cells satisfying the first predetermined condition, the total number of downlink cells, the number of supported cells reported by the terminal, and the maximum value BD or the maximum CCE value per band per cell in the case where the subcarrier spacing is the target subcarrier spacing. For example, for cells that do not support enhanced monitoring capability of the physical downlink control channel, the second threshold value is determined according to the number of cells satisfying the first predetermined condition, the total number of downlink cells, the number of supported cells reported by the terminal, and the maximum value BD or the maximum CCE value per interval per cell in the case where the subcarrier spacing is the target subcarrier spacing.

In the case where at least one scheduling cell does not support enhanced monitoring capability of the physical downlink control channel, the total number of downlink cells includes the total number of range-based downlink cells, and the total number of range-based downlink cells. The links are determined by one of the following: the sums of the numbers of all scheduled cells corresponding to the scheduling cells that support improved monitoring capability of the physical downlink control channel, where in the present invention all scheduled cells corresponding to the scheduling cells include the scheduling cells themselves and the scheduled cells , planned by planning cells; sums of the numbers of all scheduled cells corresponding to scheduling cells that support enhanced monitoring capability of the downlink physical control channel, excluding the numbers of all scheduled cells corresponding to scheduling cells that are configured without improved monitoring capability of the downlink physical control channel; sums of the numbers of all scheduling cells corresponding to scheduling cells that support enhanced monitoring capability of the downlink physical control channel, except for the numbers of all scheduling cells corresponding to scheduling cells where the banding scheme has only one band; the sum of the numbers of all scheduling cells corresponding to scheduling cells that support improved monitoring capability of the physical downlink control channel, excluding the numbers of all scheduling cells corresponding to scheduling cells that are not configured with the first downlink control information, where the first control information The downlink control information is the downlink (DL) related downlink control information (DCI) and the uplink (UL) related DCI newly defined in NR Rel-16 for unicast traffic scheduling, which also represents a new DCI or format 0_2/1_2 DCI in Rel-16; or the sum of the numbers of all configured downlink cells.

In the case where at least one scheduling cell does not support enhanced monitoring capability of the physical downlink control channel, the total number of downlink cells includes the total number of interval-based downlink cells, and the total number of interval-based downlink cells. links are determined by one of the following: the sum of the numbers of all configured downlink cells; sums of the numbers of all scheduled cells corresponding to scheduling cells that do not support enhanced monitoring capability of the physical downlink control channel, where the definition of all scheduled cells corresponding to scheduling cells has already been explained in the embodiment of the present application and will not be repeated here; the sum of the numbers of all scheduled cells corresponding to scheduling cells that do not support enhanced monitoring capability of the downlink physical control channel and the numbers of all scheduled cells corresponding to scheduling cells that support enhanced monitoring capability of the physical downlink control channel, and which configured without enhanced monitoring capability of the physical downlink control channel; the sum of the numbers of all scheduled cells corresponding to scheduling cells that do not support enhanced monitoring capability of the downlink physical control channel and the numbers of all scheduled cells corresponding to scheduling cells where the band scheme has only one range among the scheduling cells that support improved capability to monitoring a physical downlink control channel; or the sum of the numbers of all scheduling cells corresponding to scheduling cells that do not support enhanced monitoring capability of the physical downlink control channel and the numbers of all scheduling cells corresponding to scheduling cells that are not configured with the first downlink information, among the scheduling cells, which support improved monitoring capability of the downlink physical control channel, where the definition of the first downlink information has already been explained in the embodiment of the present application and will not be repeated here.

In one exemplary embodiment for a low latency ultra-reliable communication (URLLC) terminal in R16, compared to R15, the maximum number of blind decoding (referred to as the BD threshold) and/or the maximum number of non-overlapping CCEs for channel analysis (referred to as the CCE threshold) are improved , and a BD threshold and/or a CCE threshold at the binning level are determined. The following is described below using the CCE threshold as an example, and similarly, the BD threshold may also be applied in the method described below.

In the cell aggregation scenario, all scheduling cells support PDCCH monitoring capability improvement, and according to the number of cells that satisfy the condition that the subcarrier spacing of the scheduling cell is the target subcarrier spacing and the banding scheme is obtained based on the same first parameter , the total number of downlink cells, the number of supported cells reported by the terminal, and the maximum CCE value per band per cell in the case where the subcarrier spacing is the target subcarrier spacing, determine the second threshold value of the target subcarrier spacing in the band, thereby providing a solution for determining the maximum number of candidate sets for PDCCH discovery and the maximum number of non-overlapping CCEs of each subcarrier spacing on each band in the case where all scheduling cells support PDCCH monitoring capability enhancement in cell aggregation scenario to avoid exceeding the terminal's acquisition capability.

In an embodiment of the present invention, the total number of downlink cells is the total number of all downlink cells. Optionally, the total number of downlink cells may also be the total number of cells having fully or partially overlapping ranges at one time.

максимальное количество неперекрывающихся ССЕ каждого диапазона для каждого разноса поднесущих, которое также известно как максимальное значение ССЕ, рассчитывают с помощью выражения

, как показано в таблице 3.For example, each scheduling cell is assumed to receive a banding scheme based on the combination (2, 2). In FIG. 2 is a structural schematic representation of a frame structure according to one embodiment of the present application. As shown in FIG. 2, SS #0 is scheduled over multiple carriers to SS #3, while SS #4 and SS #5 are both scheduled over a single carrier (also called self carrier scheduling). Here, assuming that the number of all downlink cells is used as the total number of downlink cells, i.e.

and the number of supported cells reported by the terminal,

the maximum number of non-overlapping CCEs of each band for each subcarrier spacing, which is also known as the maximum CCE value, is calculated using the expression

as shown in Table 3.

, что не будет приводиться в качестве примера.This embodiment of the present application is described using the calculation of the maximum CCE value as an example, and the maximum value of BD is calculated in a similar manner, i.e.

which will not be given as an example.

For example, assuming that all scheduling cells in FIG. 2 are scheduled by a single carrier, i.e. CC #0 CC #5 does not have a cell indicator field (CIF) (i.e. CIF=0), the upper limit of CCE per range for each sub-carrier spacing is shown in Table 4.

In one exemplary embodiment, in a cell aggregation scenario, a portion of the scheduling cells support PDCCH monitoring capability improvement, while a portion of the scheduling cells do not support PDCCH monitoring capability improvement. This embodiment is described using an example in which cells with subcarrier spacings of 15 kHz and 30 kHz support PDCCH monitoring capability improvement, while cells with subcarrier spacings of 60 kHz and 120 kHz do not support PDCCH monitoring capability improvement, but not limited to it.

According to the number of cells that satisfy the first predetermined condition, the total number of downlink cells, the number of supported cells reported by the terminal, and the first threshold, a second subcarrier spacing target threshold is determined, thereby providing a solution for determining the maximum number of candidate sets for PDCCH detection, and the maximum number of non-overlapping CCEs of each subcarrier spacing in each band in the case where a portion of the scheduling cells support PDCCH monitoring capability enhancement in the cell aggregation scenario to avoid exceeding the terminal's detection capability.

In this embodiment, for the scheduling cells that support PDCCH monitoring capability improvement, the number of cells satisfying the first predetermined condition is the number of cells that satisfy the condition that the subcarrier spacing of the scheduling cell is the target subcarrier spacing, and the range scheme is obtained based on the same first parameter. For scheduling cells that do not support PDCCH monitoring capability enhancement, the number of cells meeting the first predetermined condition is the number of cells that meet the condition that the subcarrier spacing of the scheduling cell is the target subcarrier spacing. For a scheduling cell that does not support PDCCH monitoring capability improvement, the first scheduling cell threshold in the interval is used as the first threshold in the range.

For example, in the case where cells with subcarrier spacings of 15 kHz and 30 kHz support PDCCH monitoring capability improvement, examples of maximum CCE values of different combinations (X, Y) in 15 kHz and 30 kHz cells are shown in Table 5, and it should be noted that these values are not limited to Table 5.

, как показано в таблице 1. В случае, когда соты с разносом поднесущих 60 кГц и 120 кГц не поддерживают улучшение способности к текущему контролю PDCCH, один интервал 60 кГц и 120 кГц может быть использован как один диапазон, и ССЕ_диапазон (интервал) может быть использован как ССЕ_диапазон (X, Y).It is believed that each scheduling cell that supports PDCCH monitoring capability improvement receives a banding scheme based on the combination (2, 2). In FIG. 3 is a structural schematic representation of yet another frame structure according to one embodiment of the present application. As shown in FIG. 3, all SS #0 SS #5 are scheduled by one carrier. For a scheduling cell that does not support PDCCH monitoring capability enhancement, the first threshold value of a scheduling cell that does not support enhanced monitoring capability of the physical downlink control channel in the interval is used as the first threshold in the range. For example, the first threshold is the maximum BD value or the maximum CCE value per slot per cell in the case where the subcarrier spacing is the target subcarrier spacing, and, for example, when the first threshold is the maximum CCE value per slot per cell in the case when the subcarrier spacing is the target subcarrier spacing, the first threshold value is

, as shown in Table 1. In the case where cells with a subcarrier spacing of 60 kHz and 120 kHz do not support PDCCH monitoring capability improvement, one slot of 60 kHz and 120 kHz can be used as one band, and CCE_band (slot) can be used as CCE_range (X, Y).

и количество поддерживаемых сот, сообщаемое терминалом,

максимальное значение ССЕ каждого диапазона для каждого разноса поднесущих рассчитывают с помощью

как показано в таблице 6.Here, assuming that the number of all downlink cells is used as the total number of downlink cells, i.e.

and the number of supported cells reported by the terminal,

the maximum CCE value of each band for each subcarrier spacing is calculated using

as shown in table 6.

In one exemplary embodiment, in a cell aggregation scenario, a portion of the scheduling cells support PDCCH monitoring capability improvement, while a portion of the scheduling cells do not support PDCCH monitoring capability improvement. This embodiment is described using an example in which cells with subcarrier spacings of 15 kHz and 30 kHz support PDCCH monitoring capability improvement, while cells with subcarrier spacings of 60 kHz and 120 kHz do not support PDCCH monitoring capability improvement, but not limited to it.

According to the number of cells that satisfy the first predetermined condition, the total number of downlink cells, the number of supported cells reported by the terminal, and the first threshold, a second subcarrier spacing target threshold is determined, thereby providing a solution for determining the maximum number of candidate sets for PDCCH detection, and the maximum number of non-overlapping CCEs of each sub-carrier spacing in each band in the case where a portion of the scheduling cells support PDCCH monitoring capability enhancement in the cell aggregation scenario to avoid exceeding the terminal's detection capability.

In one exemplary embodiment, in a cell aggregation scenario, a portion of the scheduling cells support PDCCH monitoring capability improvement, while a portion of the scheduling cells do not support PDCCH monitoring capability improvement. This embodiment is described using an example in which cells with subcarrier spacings of 15 kHz and 30 kHz support PDCCH monitoring capability improvement, while cells with subcarrier spacings of 60 kHz and 120 kHz do not support PDCCH monitoring capability improvement, but not limited to it. In yet another example, for one cell or cell group, the base station configures one cell or cell group to support PDCCH monitoring ability improvement or not to support PDCCH monitoring ability improvement.

OS is an abbreviation for an orthogonal frequency division multiplexing symbol (OFDM symbol), and the corresponding OS index indicates an orthogonal frequency division multiplexing symbol index.

In NR Rel-15, the PDCCH monitoring capability is the maximum BD value (or maximum CCE value) determined per interval per cell, which is called R15 capability. In NR Rel-16, the PDCCH monitoring capability is improved and a maximum CCE value (or maximum BD value) per band per cell is defined, which is called R16 capability. However, the method of using the ability R15 and ability R16 is not specified in the prior art. One possible way is to use R15 capability for Enhanced Mobile Broadband (eMBB) traffic and R16 capability for URLLC traffic. Yet another possible method is to configure the terminal to use R15 capability or R16 capability regardless of the type of traffic. The first of the above methods limits R16 to only one type of traffic, while the second method cannot use R15 capability and R16 capability at the same time, and both methods have certain limitations.

In one embodiment of the present application, a method for using a threshold is provided. The method includes: a method of using different thresholds is determined in one of the following possible ways: different thresholds are used for different formats of downlink control information, respectively; different thresholds are used for different search spaces, respectively; or different sets of search spaces are configured for the same threshold, and different sub-thresholds are configured for different sets of search spaces, respectively.

In this embodiment, the method of using different threshold values for different downlink control information formats respectively includes: obtaining a downlink control information format; and a threshold value to be used is determined according to the format of the downlink control information; wherein the threshold includes an interval-based first threshold and a range-based second threshold.

In this embodiment, a method for using a threshold is provided that can allow PDCCH monitoring capability enhancement to be applied to schedule multiple types of traffic, thereby achieving flexible use of the improved PDCCH monitoring capability.

For example, capability R15 is used for downlink control information R15 and capability R16 is used for downlink control information R16. The R16 downlink control information is a new downlink control information (DCI) format introduced by the 16th edition of NR (for example, the new DCI format is the DCI format for uplink traffic channel scheduling and the DCI format for downlink traffic channel scheduling). link) which is used for scheduling both URLLC traffic and eMBB R16 traffic. Here, R16 capability is associated with DCI R16, which can schedule both eMBB traffic and URLLC traffic.

In this embodiment, a method for configuring different sets of search spaces for the same threshold and configuring different sub-thresholds for different sets of search spaces, respectively, includes: in the case of configuring a range-based second threshold, configuring at least two groups of sets of search spaces; and respectively determining a sub-threshold corresponding to each of the two search space set groups, where optionally the sub-threshold corresponding to each of the two search space set groups is distinguished by higher level configuration or predetermination.

For example, when capability R16 is configured, X search space set groups are configured, and the second threshold value C_x, x=0, 1, ..., X-1 corresponding to each search space set group, and the sum of the second threshold values corresponding to each group are respectively determined. , is the ability of R16. Optionally X=2 and here the second thresholds C_0 and C_1 corresponding to the two groups are used for eMBB and URLLC respectively, or used for eMBB and eMBB/URLLC respectively, or used for DCI R15 and DCI R16 respectively, or used for DCI R15 and DCI R15/DCI R16, respectively, where eMBB/URLLC stands for eMBB and URLLC, and DCI R15/DCI R16 stands for DCI R15 and DCI R16.

In this embodiment, the method of using different threshold values for different sets of search spaces, respectively, includes: obtaining configuration information related to the search space; and a threshold value to be used is determined according to the configuration information; wherein the threshold includes an interval-based first threshold and a range-based second threshold.

The threshold value to be used is determined according to the configuration information as follows: in the case where the first downlink control information and the second downlink control information are configured in the same search space, the threshold value to be used is determined according to the order or the traffic type indicated in the first downlink control information.

Optionally, the first downlink control information may be DCI DL and DCI UL newly defined in NR Rel-16 for scheduling unicast traffic, which is also new DCI or DCI format 0_2/1_2 in Rel-16. The second downlink control information may be DCI DL and DCI UL already existing in NR Rel-15 for scheduling unicast traffic, which is also non-alarm DCI or DCI format 0_1/1_1 in Rel-15.

For example, if the type of traffic indicated in the first downlink control information is URLLC (or high priority), the threshold to be used is the range-based second threshold.

In a case where the first downlink control information and the second downlink control information are not detected, the method further includes: one threshold is randomly selected as a threshold to be used; or one threshold value is randomly selected as a threshold value to be used, and in case the resources used or detections exceed the threshold value to be used, one of the remaining threshold values is used as the threshold value to be used; or the sum of all threshold values is calculated and the result of the calculation is used as the threshold value to be used.

In this embodiment, the threshold value to be used is determined according to the configuration information as follows: in the case where the first downlink control information and the second downlink control information are configured in the same search space, the range-based second threshold value to be used is determined according to the first downlink control information, and the interval-based first threshold to be used is determined according to the second downlink control information.

The method for determining the threshold to be used in the case where the first downlink control information and the second downlink control information are not detected is the same as the method used in the embodiments described above, and details are not repeated here. .

In this embodiment, the configuration information related to the search space is obtained as follows: a candidate set and an initial control channel block are configured for the first downlink control information and a candidate set and an initial control channel block are configured for the second downlink control information in the search space respectively, both candidate sets and control channel source blocks are used as configuration information.

With the above solution, in the case where the first downlink control information and the second downlink control information are configured in the same search space, it is possible to distinguish between the R15 capability and the R16 capability so that the improved PDCCH monitoring capability can be fully utilized. and PDCCH monitoring capability related to R15, thereby improving scheduling flexibility.

The candidate set (X, Y) reported by the terminal in the embodiments described above may comprise at least one of: {(7, 3)}, {(4, 3), (7, 3)}, or {( 2, 2), (4, 3), (7, 3)}. The range scheme in an interval is determined by the candidate set (X, Y) reported by the terminal and the CORESET PDCCH and the search space. The number of ranges does not exceed the result of the operation floor (14/X), where X is the minimum X in the combination (X, Y) transmitted by the terminal. Since the minimum X is 2, the number of ranges does not exceed 7. When the number of monitoring opportunities (MOs) corresponding to allocated search spaces (SS) is more than 7, the resulting range is invalid. Therefore, it is necessary for the terminal to discard/not detect some monitoring capabilities so that the number of monitoring capabilities is no more than 7. Therefore, the question of how to determine the monitoring capabilities to be discarded is an actual task to be solved.

In one embodiment of the present application, a method for correcting information is provided. The method includes: when the number of monitoring opportunities corresponding to the search spaces exceeds a predetermined threshold value, the monitoring opportunities satisfying the predetermined condition are discarded.

By solving this embodiment, bands can be allocated efficiently so that improved PDCCH monitoring capability can be used, thereby increasing scheduling flexibility.

The predetermined condition includes one of the following: discarding is performed based on the order of the search space indexes; discarding is performed based on the order of the lengths of the control resource sets corresponding to the search spaces, or the lengths of the control resource sets corresponding to the monitoring capabilities; or dropping is performed based on the order of the number of monitoring opportunities corresponding to the search spaces.

In one exemplary embodiment, in the case where the number of monitoring opportunities corresponding to search spaces exceeds a predetermined threshold value, the dropping performed based on the order of search space indexes can be optimized such that: in the case where the number of monitoring opportunities corresponding to search spaces exceeds a predetermined threshold value, monitoring capabilities are discarded based on the order of search space indexes in descending order until the number of monitoring capabilities is no more than 7.

FIG. 5 is a block diagram of an initial monitoring capability configuration according to one embodiment of the present application. As shown in FIG. 5, the number of monitoring capabilities configured is 8, which is more than 7, and the numbers in the shaded background in the figure indicate search space indices. In one exemplary embodiment, in the case where the number of monitoring capabilities corresponding to the search spaces exceeds a predetermined threshold value, discarding based on the order of the lengths of the control resource sets corresponding to the search spaces or the lengths of the control resource sets corresponding to the monitoring capabilities may be optimized such that: in the case where the number of monitoring capabilities corresponding to the search spaces exceeds a predetermined threshold value, the monitoring capabilities are discarded based on the order of the lengths of the control resource sets corresponding to the search spaces in descending order or the order of the lengths of the control resource sets, corresponding to the monitoring capabilities in descending order until the number of monitoring capabilities is no more than 7. FIG. 6 is a block diagram of a monitoring capability configuration after drop processing according to one embodiment of the present application. As shown in FIG. 6, the monitoring opportunity where the length of the control resource set corresponding to the search spaces is 2 symbols is discarded to ensure that the number of monitoring opportunities does not exceed 7 so that the ranging is valid.

In one exemplary embodiment, when the number of monitoring opportunities corresponding to the search spaces exceeds a predetermined threshold value, discarding based on the order of the number of monitoring opportunities corresponding to the search spaces can be optimized such that: in the case where the number of monitoring opportunities corresponding to the search spaces control corresponding to the search spaces exceeds a predetermined threshold, the monitoring capabilities are discarded based on the order of the number of monitoring capabilities corresponding to the search spaces in descending order until the number of monitoring capabilities is no more than 7.

Optionally, for a single search space having multiple monitoring capabilities, the order of discarding monitoring capabilities includes the following: monitoring capabilities are discarded in descending order or in ascending order according to OFDM symbol indices; or first discard the monitoring capabilities adjacent to the longer CORESET duration monitoring capability.

FIG. 7 is a block diagram of another initial monitoring capability configuration according to one embodiment of the present application. As shown in FIG. 7, the number of configured MOs is 8, which is more than 7. The numbers in the shaded background in the figure indicate the indexes of the search spaces. FIG. 8 is a block diagram of yet another monitoring capability configuration after drop processing, according to one embodiment of the present application. As shown in FIG. 8, a monitoring capability in a search space having 5 monitoring capabilities is discarded to ensure that the number of monitoring capabilities does not exceed 7 so that the ranging is valid.

The degree of splitting of enhanced resource allocation in the frequency domain type 1 (FDRA type 1, continuous resource allocation mode) is configured by a radio resource control (RRC) parameter. Optionally, the configuration value is an integer number of resource blocks (RBs), such as 1, 2, 4, 8, or 16 RBs. The split degree is the initial split degree and the length specification split degree with the same value. However, in practical applications, none of the RRC parameters may be configured, resulting in incorrect reception of the traffic channels.

In one embodiment of the present application, a method for correcting information is provided. The method includes the following: in the case where the granularity configuration parameter of the improved resource allocation in the frequency domain type 1 is not configured, the default value of the granularity configuration parameter is determined to be one RB or one resource block group (RBG).

For example, in the case where no RRC parameter is configured, the RRC parameter may be specified in one of the following ways: the default value of the granularity configuration parameter is defined as one RB, i.e., the tilings are assumed to be the same as the default granularity of FDRA 1 th type related to Rel-15; the default value of the granularity configuration parameter is determined to be one RBG (when RBG is configured), where the RBG size is the resource block size configured for FDRA type 0, that is, the granularity is assumed to be the same as the RBG granularity in the default system; or the default is one RBG when an RBG is configured, and the default is one RB when no RBG is configured.

With the solution provided in this embodiment, when no RRC parameter is configured, an accurate value can be obtained so that inconsistent understanding between the terminal and the base station is prevented, thereby ensuring correct reception of the traffic channels.
