Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a method, apparatus, terminal, and medium for determining PDCCH monitoring information. Background Art

[0002] In a wireless communication system, a user equipment (UE) can blindly detect a physical downlink control channel (PDCCH) to obtain information such as the physical resource location occupied by downlink control information (DCI) and the resource size occupied by the DCI.

[0003] In a Long Term Evolution (LTE) system, a terminal performs downlink channel evaluation based on a cell-specific reference signal (CRS), and then blindly detects in a search space according to the downlink channel evaluation result. In LTE, the search space for UE blind detection is composed of all or part of the control channel elements (CCEs) in all the control channel elements (CCEs) of the PDCCH according to a certain aggregation level and a certain PDCCH candidate set, so that the UE can blindly detect the PDCCH in this search space.

[0004] However, since the search space configuration information of the current terminal is statically configured, when the terminal blindly detects a candidate PDCCH based on the PDCCH monitoring information determined according to the search space configuration information, the terminal needs to blindly detect the candidate PDCCH periodically using the same PDCCH monitoring information. In this way, when the PDCCH changes, the terminal may not be able to detect it in time, resulting in the terminal consuming a large amount of power and computing resources to blindly detect these candidate PDCCHs. Summary of the Invention

[0025] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, rather than all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0026] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are usually of the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "or" in the present application means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, Scenario 1: including A and not including B; Scenario 2: including B and not including A; Scenario 3: including both A and B. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0027] The term "indication" in the present application can be either a direct indication (or an explicit indication) or an indirect indication (or an implicit indication). Among them, a direct indication can be understood as that the sender clearly informs the receiver of specific information, operations to be performed, or request results, etc. in the sent indication; an indirect indication can be understood as that the receiver determines the corresponding information according to the indication sent by the sender, or makes a judgment and determines the operations to be performed or request results, etc. according to the judgment result.

[0028] The terms "at least one (item)", "at least one of", etc. in the present application refer to any one, any two or more combinations of the objects it contains. For example, at least one (item) of a, b, and c can represent: "a", "b", "c", "a and b", "a and c", "b and c", and "a, b, and c", where a, b, and c can be single or multiple. Similarly, "at least two (items)" means two or more, and its meaning is similar to that of "at least one (item)".

[0029] The following will explain the technical terms involved in the technical solutions provided in the embodiments of this application:

[0030] 1) New Radio (NR) Search Space

[0031] In 5G NR, the UE needs to fully obtain the time-frequency domain resource configuration information of the PDCCH before it can further demodulate the PDCCH. The current protocol design is to encapsulate the frequency domain resource information of the PDCCH and the number of orthogonal frequency division multiplexing (OFDM) symbols occupied in the time domain and other information in the Control Resource Set (CORESET), and encapsulate the starting OFDM symbol of the PDCCH, the monitoring period, the associated CORESET and other information in the search space.

[0032] The search space can be considered to consist of a set of candidate PDCCHs that the UE needs to blindly detect. The search space of the PDCCH is divided into a Common Search Space (CSS) and a UE Specific Search Space (USS). The former corresponds to a group of UEs, that is, the common control information for a group of UEs is sent through the CSS. The USS corresponds to a specific UE, and the exclusive scheduling information of the UE can be sent through the USS.

[0033] When the UE detects the PDCCH, it needs to detect the DCI according to a specific DCI format and RNTI on different candidate PDCCHs. The resource position of the candidate PDCCH is determined by the starting position and aggregation level of the Control Channel Element (CCE). When the UE detects the DCI, it does not know whether the base station has sent the DCI, nor does it know the aggregation level and starting position of the CCE actually used to send the DCI. The UE needs to try each candidate PDCCH one by one, and this process is called the blind detection of the PDCCH.

[0034] Multiple search spaces (up to 10) can be configured within each BWP, which are used to set different search space types, match different service types and scenarios, or transmit different DCI formats, etc. Each search space is associated with a Control Resource Set (CORESET), and the type, period, size, etc. of each search space can be configured independently. The parameters that need to be configured for the search space include:

[0035] The index ID (searchSpaceID) of the search space;

[0036] CORESET ID (controlResourceSetID) associated with the search space;

[0037] PDCCH monitoring period and offset value (monitoringSlotPeriodicityAndOffset), in units of slots. The UE determines the slots for monitoring PDCCH based on this parameter;

[0038] Duration, the number of consecutive slots to be monitored starting from each slot where monitoring begins;

[0039] PDCCH monitoring pattern within a slot (monitoringSymbolsWithinSlot). A 14-bit bitmap indicates the starting symbol position for PDCCH monitoring in each slot. Each bit corresponds to an OFDM symbol within the slot, and a value of "1" indicates that the OFDM symbol corresponding to this bit is the starting position for monitoring;

[0040] The nrofCandidates parameter, which includes the aggregation level information of the search space and the number of candidate PDCCHs (PDCCH candidates) for each aggregation level, i.e., the UE needs to blindly detect all PDCCH candidates corresponding to the configured aggregation levels;

[0041] Type of search space (searchSpaceType) and the DCI format (Format) for scheduling.

[0042] 2) For the subcarrier spacing (Subcarrier Spacing, SCS) configuration μ, the number of slots in a system frame is represented by The PDCCH monitoring period corresponding to the above search space is represented by k s The offset value of the PDCCH monitoring slots within the period is represented by o s Then, for the slot f in system frame n When it satisfies: This slot is a PDCCH monitoring slot. That is, the starting point of the PDCCH monitoring period in NR is defaulted to slot-0 of the first slot in frame-0.

[0043] For example, Figure 1As shown, assume that the PDCCH monitoring period is 10 slots, namely slot-0 to slot-10, where the slot offset is 5, the number of continuously monitored slots is 1, the number of time-domain symbols of the CORESET associated with the search space is 2, and the symbol positions are 0 and 7. Then, in this configuration, based on slot-0 of starting position frame-0, the UE determines each monitoring period and determines the slot positions to be monitored in each monitoring period, that is, in Figure 1 the UE monitors candidate PDCCHs on symbol 0-1 and symbol 7-8 of slot-5 in each monitoring period.

[0046] Next, with reference to the accompanying drawings, the method, apparatus, terminal, and medium for determining PDCCH monitoring information provided by the embodiments of this application will be described in detail through some embodiments and their application scenarios.

[0047] Figure 3 The flowchart of a method for determining PDCCH monitoring information provided by an embodiment of this application is shown, as Figure 3 shown. The method for determining PDCCH monitoring information may include the following steps 201 and 202:

[0048] Step 201, the terminal obtains first information.

[0049] In some embodiments of this application, the above first information is the information received by the terminal from the network-side device.

[0050] In some embodiments of this application, the above first information is used to adjust the initial search space configuration information of the terminal.

[0051] In some embodiments of this application, the above first information is carried by the first PDCCH sent in the first search space, or carried by the channel scheduled by the first PDCCH.

[0052] In some embodiments of this application, the above first search space is the search space corresponding to the initial search space configuration information.

[0053] In some embodiments of the present application, the above-mentioned first search space includes at least one candidate PDCCH.

[0054] In some embodiments of the present application, the above-mentioned first PDCCH is determined by the terminal based on the first PDCCH monitoring information.

[0055] Optionally, in some embodiments of the present application, before the terminal obtains the first information, the terminal determines the first PDCCH monitoring information according to the configuration parameters of the candidate PDCCH included in the initial search space configuration information, blindly detects at least one candidate PDCCH in the first search space, and determines at least one candidate PDCCH in the first search space as the above-mentioned first PDCCH. Then, the terminal can receive the first information on the first PDCCH, or receive the first information on the channel scheduled by the first PDCCH.

[0056] Exemplarily, in the case where the above-mentioned first information is carried by the first PDCCH or the channel scheduled by the first PDCCH, the first information may be carried in the first signaling.

[0057] Exemplarily, the above-mentioned first signaling may be DCI signaling, may also be Medium Access Control (MAC) signaling, or may also be Radio Resource Control (RRC) signaling.

[0058] In one example, the network-side device may indicate the first information through RRC signaling, where the first information includes the value after the parameter configuration of the corresponding search space is adjusted.

[0059] In one example, the network-side device indicates to the terminal, through RRC signaling, the set of values corresponding to different configuration information in the search space configuration information, and indicates or activates the value of one of the configuration information in the search space configuration information through MAC signaling or DCI signaling.

[0060] For example, the network-side device configures, through RRC signaling, the set of values of the PDCCH monitoring period for the terminal as {40, 80, 160} time slots, and indicates, through MAC CE signaling or DCI signaling, that the PDCCH monitoring period is 80 time slots.

[0061] In another example, the network-side device configures, through RRC signaling, the value combinations of multiple configuration information in the search space configuration information, and indicates or activates the value combination of one of the configuration information in the search space configuration information through MAC signaling or DCI signaling.

[0062] For example, in the RRC signaling, combination 1 and combination 2 are configured. Among them, combination 1 is {time offset 5 slots, monitoring period 40 slots, bitmap-1}, and combination 2 is {time offset 10 slots, monitoring period 80 slots, bitmap-2}. One of the two combinations is activated for the terminal to use through MAC signaling or DCI signaling.

[0063] In some embodiments of the present application, the above first information includes at least one adjustment information.

[0064] In some embodiments of the present application, the above one adjustment information corresponds to at least one search space configuration information.

[0065] In some embodiments of the present application, the corresponding rule between the above adjustment information and at least one search space configuration information is determined by the network side device configuration or determined by a predefined rule.

[0066] It should be noted that each of the above adjustment information is an independent resource block (block), and each resource block is configured by the network side device. Among them, the size of each block can be determined according to the predefined size, or can be determined by the network side device configuration or implicitly determined by other parameters.

[0067] In some embodiments of the present application, the size of the above first information in the first signaling is determined according to the number of search spaces or search space groups to be adjusted configured by the network side device and the size of each adjustment information, and is mapped to each resource block in the order of the search space or search space group ID. Among them, the domain size corresponding to each search space or search space group ID is the size of each adjustment information.

[0068] For example, there are 3 search spaces {Search space-1, Search space-2, Search space-3}, and the first information contains 3 adjustment information blocks {Information block-1, Information block-2, Informationblock-3}. The adjustment information blocks and the search spaces correspond in order according to the ID. Or each adjustment information contains the search space or search space combination associated with it, so that the adjustment information blocks can correspond one by one with the search space or search space combination.

[0069] Step 202: The terminal adjusts the initial search space configuration information based on the first information to obtain the second PDCCH monitoring information corresponding to the adjusted initial search space configuration information.

[0070] In some embodiments of the present application, the above "adjusting the initial search space configuration information" may include at least one of the following: modifying the initial search space configuration information, adding to the initial search space configuration information.

[0071] In some embodiments of the present application, the terminal may adjust some or all of the content of the initial search space configuration information according to the first information, or add some content to the initial search space configuration information.

[0072] Optionally, in some embodiments of the present application, after the terminal obtains the first information, it adjusts the initial search space configuration information according to the adjustment information included in the first information to obtain the adjusted initial search space configuration.

[0073] It should be noted that the initial search space configuration information mentioned in the embodiments of the present application is the search space configuration information before the terminal receives the adjustment of the first information. In other words, the initial search space configuration information may be the search space configuration information initially received by the terminal or the search space configuration information currently used by the terminal, which is not limited in the present application.

[0074] In the PDCCH monitoring information determination method provided in the embodiments of the present application, the terminal obtains the first information, which is used to adjust the initial search space configuration information of the terminal, and the initial search space configuration information is used to determine the first PDCCH monitoring information; the terminal adjusts the initial search space configuration information based on the first information to obtain the second PDCCH monitoring information corresponding to the adjusted initial search space configuration information. In this solution, the terminal can adjust the search space configuration information according to the obtained first information, so that the terminal can determine new PDCCH monitoring information according to the adjusted search space configuration information, so that when the terminal performs PDCCH blind detection using the new PDCCH monitoring information, it can more accurately monitor the candidate PDCCH, thereby reducing the power consumed by the terminal for PDCCH blind detection.

[0075] Optionally, in some embodiments of the present application, the initial search space configuration information of the terminal is used to determine the first PDCCH monitoring information.

[0076] Optionally, in some embodiments of the present application, the above first PDCCH monitoring information includes at least one of the following:

[0077] The time domain position of PDCCH monitoring;

[0078] The frequency domain position of PDCCH monitoring;

[0079] The aggregation level of PDCCH monitoring;

[0080] The candidate PDCCH for PDCCH monitoring;

[0081] The DCI format of the downlink control information monitored by PDCCH;

[0082] The position of the candidate PDCCH monitored by PDCCH;

[0083] The starting monitoring position of the candidate PDCCH monitored by PDCCH.

[0084] In some embodiments of the present application, the starting monitoring position of the candidate PDCCH monitored by the above PDCCH may include at least one of the following:

[0085] The starting monitoring positions of PDCCH candidates corresponding to different aggregation levels respectively;

[0086] The starting PDCCH candidate monitoring position among all PDCCH candidates;

[0087] The default starting monitoring position of the PDCCH candidate is 1.

[0088] Optionally, in some embodiments of the present application, the configuration parameters of the time domain position for PDCCH monitoring in the above initial search space configuration information include at least one of the following:

[0089] The PDCCH monitoring period;

[0090] The first time offset value;

[0091] The first monitoring position indication information;

[0092] The number of consecutive time units for PDCCH monitoring;

[0093] The second time offset value;

[0094] The PDCCH monitoring position of each sub-time unit in the time unit for PDCCH monitoring.

[0095] In some embodiments of the present application, the above PDCCH monitoring period may be indicated in time unit granularity, such as time slots, sub-time slots, frames, or sub-frames, etc.

[0096] It can be understood that the above PDCCH monitoring period may be a period of 10 time slots in a group, or a period of 15 time slots in a group.

[0097] In some embodiments of the present application, the above first time offset value is used to determine the monitoring position in the PDCCH monitoring period.

[0098] In some embodiments of the present application, after the terminal receives the first time offset value included in the first information, it determines the time domain position after the first time offset value in a certain PDCCH monitoring period as the monitoring position.

[0099] In some embodiments of the present application, the above first monitoring position indication information is used to indicate whether each time unit in the PDCCH monitoring period needs to be monitored.

[0100] In some embodiments of the present application, the above first monitoring position indication information may be a bitmap sequence or a binary sequence. Among them, if the first monitoring position indication information is a bitmap sequence, the positions where "1" is located in the bitmap sequence indicate that the time units corresponding to these positions need to be monitored. If the first monitoring position indication information is a binary sequence, the number obtained after converting the binary sequence to decimal indicates which time unit in the PDCCH monitoring period needs to be monitored.

[0101] For example, taking the PDCCH monitoring period as 10 slots as an example, if the bitmap sequence is a 10-bit sequence 0001100000, it means that the terminal monitors in the 4th and 5th slots of the PDCCH monitoring period.

[0102] Example 1, refer to Figure 4 As shown, the configuration information of the initially configured search space SearchSpace-1 includes: the PDCCH monitoring period T default , that is, the above PDCCH monitoring period, the time offset time_offset of the start position of this monitoring period relative to the first time slot of frame-0 default , that is, the above second time offset value, the indication bitmap of whether each time unit in this monitoring period is monitored default , that is, taking the above first monitoring position indication information as a bitmap sequence as an example. The PDCCH monitoring period T default Taking slots as the unit, it is 20 slots, and the offset value of the start position of the monitoring period is 5 slots. The bitmap with slots as the granularity is used to indicate the slots that the terminal needs to monitor. Starting from each slot where monitoring begins, the number of consecutive slots to be monitored is 1. Assume the bitmap default is [01010011101011010100], then it can be obtained that the slot positions to be monitored are: the 7th, 9th, 12th, 13th, 14th, 16th, 18th, 19th, 21st, and 23rd slots, that is, Figure 4 the shaded part in

[0103] In some embodiments of the present application, the number of consecutive time units for PDCCH monitoring can be indicated in time unit granularity, such as slots, sub-slots, frames, or sub-frames, etc.

[0104] In some embodiments of the present application, the above second time offset value is used to determine the start position of the PDCCH monitoring period.

[0105] In some embodiments of the present application, the above second time offset value is the time offset value of the PDCCH monitoring period relative to the radio frame or radio subframe where the monitoring period is located.

[0106] In some embodiments of the present application, after the terminal receives the second time offset value included in the first information, according to the second time offset value, it determines the start position of the PDCCH monitoring period in the radio frame or radio subframe.

[0107] In some embodiments of the present application, the sub-time unit in each sub-time unit of the time unit for PDCCH monitoring can be an OFDM symbol in the PDCCH monitoring position.

[0108] Optionally, in some embodiments of the present application, the above second PDCCH monitoring information includes at least one of the following:

[0109] The time domain position of PDCCH monitoring;

[0110] The frequency domain position of PDCCH monitoring;

[0111] The aggregation level of PDCCH monitoring;

[0112] The candidate PDCCH for PDCCH monitoring;

[0113] The DCI format of the downlink control information for PDCCH monitoring;

[0114] The position of the candidate PDCCH for PDCCH monitoring;

[0115] The start monitoring position of the candidate PDCCH for PDCCH monitoring.

[0116] In some embodiments of the present application, the start monitoring position of the candidate PDCCH for PDCCH monitoring may include at least one of the following:

[0117] A) The start monitoring positions of PDCCH candidates corresponding to different aggregation levels respectively;

[0118] B) The start PDCCH candidate monitoring position among all PDCCH candidates;

[0119] C) The default start monitoring position of the PDCCH candidate is 1.

[0120] Example 2. The aggregation levels of PDCCH monitoring included in the SearchSpace-1 configuration information and the number of PDCCH candidates corresponding to each aggregation level are as follows:

[0121] aggregationLevel1: n8,

[0122] aggregationLevel2: n6,

[0123] aggregationLevel4: n4,

[0124] aggregationLevel8: n2,

[0125] aggregationLevel16: n2.

[0126] For A), if the network-side device configures the starting monitoring positions of the PDCCH candidates corresponding to the aggregation levels {1, 2, 4, 8, 16} to be {5, 3, 2, 1, 1}, then the terminal does not need to blindly detect all PDCCH candidates. For example, for aggregationLevel1, it only needs to start blindly detecting from the 5th PDCCH candidate, and for aggregationLevel2, it only needs to start blindly detecting from the 3rd PDCCH candidate.

[0127] For B), if the network side configures the starting monitoring positions of all PDCCH candidates corresponding to all aggregation levels, then first sort all 22 PDCCH candidates according to the aggregation levels, and then determine from which PDCCH candidate to start blindly detecting according to the configured starting monitoring position of the PDCCH candidate. For example, if the configured starting monitoring position of the PDCCH candidate is 21, then the terminal only needs to start blindly detecting from the 21st PDCCH candidate, that is, start blindly detecting from the first PDCCH candidate corresponding to aggregationLevel16.

[0128] In this way, the terminal can blindly detect a specific PDCCH according to the configured starting monitoring position, without blindly detecting all PDCCHs, so as to reduce the number of blind detections, thereby reducing the power of the terminal for PDCCH blind detection.

[0129] Optionally, in some embodiments of this application, each adjustment information included in the above first information includes at least one of the following:

[0130] Adjustment information for the time-domain position used for PDCCH monitoring;

[0131] Adjustment information for the frequency-domain position used for PDCCH monitoring;

[0135] Adjustment information for the DCI format used for PDCCH monitoring;

[0136] Adjustment information for the starting monitoring position of the candidate PDCCHs used for PDCCH monitoring;

[0137] Adjustment information for the positions of the candidate PDCCHs used for PDCCH monitoring;

[0138] Newly added PDCCH monitoring information.

[0139] In some embodiments of the present application, if the above first PDCCH monitoring information only includes the PDCCH monitoring period, the first time offset value, and the second time offset value, the newly added PDCCH monitoring information may be any one, or more, of the candidate PDCCHs for PDCCH monitoring, the downlink control information DCI format for PDCCH monitoring, the position of the candidate PDCCHs for PDCCH monitoring, or the starting monitoring position of the candidate PDCCHs for PDCCH monitoring.

[0140] In some embodiments of the present application, the above adjustment information for the starting monitoring position of the candidate PDCCHs used for PDCCH monitoring includes at least one of the following:

[0141] The adjusted starting monitoring positions of the PDCCH candidates corresponding to different aggregation levels;

[0142] The adjusted starting monitoring position of the PDCCH candidates among all PDCCH candidates.

[0143] Second time offset adjustment information, which is used to indicate the adjusted starting position of the PDCCH monitoring period;

[0144] The third time offset value of the adjusted starting monitoring position of the PDCCH monitoring period relative to the starting monitoring position of the PDCCH monitoring period before adjustment.

[0145] Example 3, in combination with Example 2, taking the starting monitoring position of PDCCH candidates in all adjusted PDCCH candidates as an example, for Search Space-1, the initial starting monitoring positions of PDCCH candidates corresponding to aggregation levels {1, 2, 4, 8, 16} are {5, 3, 2, 1, 1}. The first piece of information can adjust the starting monitoring position of the PDCCH candidate corresponding to aggregation level 1 from 5 to 2, and the starting monitoring positions of PDCCH candidates corresponding to other aggregation levels remain unchanged. Then, the adjusted starting monitoring positions of PDCCH candidates corresponding to aggregation levels {1, 2, 4, 8, 16} are {2, 3, 2, 1, 1}.

[0146] In some embodiments of the present application, the adjustment information for the time domain position used for PDCCH monitoring includes at least one of the following:

[0147] Adjustment information for the PDCCH monitoring period;

[0148] First time offset adjustment information;

[0149] Second monitoring position indication information;

[0150] The number of consecutive time units for PDCCH monitoring that need to be adjusted;

[0151] Adjustment information for the starting position of the PDCCH monitoring period;

[0152] The adjusted PDCCH monitoring position of the sub-time unit in the time unit for PDCCH monitoring;

[0153] Effective time information for the adjusted time domain position used for PDCCH monitoring, and the effective time information includes the start effective time and the effective time range.

[0154] Exemplarily, the adjustment information for the PDCCH monitoring period can be indicated in time unit granularity, such as time slot, sub-time slot, frame, or sub-frame, etc. For example, the PDCCH monitoring period is adjusted to 10 slots.

[0155] Exemplarily, the above first time offset adjustment information is used to indicate the adjustment position of the first time offset value, where the first time offset value refers to the description of the first time offset value in the above first PDCCH monitoring information, which will not be elaborated here.

[0156] Exemplarily, the above second monitoring position indication information is used to indicate whether each time unit after adjustment in each PDCCH monitoring period needs to be monitored.

[0157] Example 4, in combination with Example 1 (refer toFigure 4 ), for example, as Figure 5 shown. For example, if the first information indicates that the terminal adjusts the PDCCH monitoring period T in the SearchSpace-1 configuration information to T default , and the time offset time_offset adjust remains unchanged, and the indication bitmap of whether to monitor each time unit within the PDCCH monitoring period default is adjusted to bitmap default . For example, if T adjust is 30 slots and bitmap adjust = [111100101001010000001001010000], then the corresponding slot positions to be monitored can be obtained as: the 6th to 9th, 12th, 14th, 17th, 19th, 26th, 29th, and 31st slots, that is, adjust the shaded part in Figure 5 .

[0158] Exemplarily, the number of consecutive time units to be adjusted for PDCCH monitoring can be indicated in time unit granularity, such as slots, sub - slots, frames, or sub - frames, etc.

[0159] Exemplarily, the "effective time information" in the effective time information of the adjusted time - domain position for PDCCH monitoring includes the start effective time and the effective time range.

[0160] Exemplarily, the above - mentioned start effective time is the time when the terminal starts PDCCH monitoring at the adjusted time - domain position of the PDCCH based on the second PDCCH monitoring information.

[0161] Exemplarily, the above - mentioned start effective time is determined based on at least one of the following:

[0162] The end monitoring position of the PDCCH monitoring period,

[0163] The reception time of the first information,

[0164] The end position of the PDCCH monitoring period corresponding to the first information;

[0165] The second information and the fourth time offset value.

[0166] Exemplarily, the "PDCCH monitoring period corresponding to the first information" refers to the monitoring period corresponding to the PDCCH carrying or scheduling the first information.

[0167] Among them, the second information includes at least one of the following:

[0168] The start position of the first time unit, where the first time unit is the first time unit of the radio frame or subframe in which the PDCCH monitoring period is located;

[0169] The start position of the PDCCH monitoring period before adjustment;

[0170] The end position of the PDCCH monitoring period before adjustment;

[0171] The start position or end position of the PDCCH monitoring period corresponding to the first information;

[0172] The reception time of the first information.

[0173] For example, when the second information includes the start position of the first time unit, the terminal determines the start effective time according to the time domain position corresponding to the fourth time offset value of the start position of the first time unit.

[0174] For example, when the second information includes the start position of the PDCCH monitoring period before adjustment, the terminal determines the start effective time according to the time domain position corresponding to the fourth time offset value of the start position of the PDCCH monitoring period before adjustment.

[0175] For example, when the second information includes the end position of the PDCCH monitoring period before adjustment, the terminal determines the start effective time according to the time domain position corresponding to the fourth time offset value of the end position of the PDCCH monitoring period before adjustment.

[0176] For example, when the second information includes the reception time of the first information, the terminal determines the start effective time as the reception time of the first information. That is, when the terminal receives the first information, it immediately adjusts the time domain position of PDCCH monitoring according to the adjustment information of the time domain position for PDCCH monitoring included in the first information.

[0177] It should be noted that the above fourth time offset value can be configured by the network side device or agreed upon by the protocol.

[0178] Exemplarily, the above effective time range is the time range during which the terminal performs PDCCH monitoring at the time domain position of the adjusted PDCCH based on the second PDCCH monitoring information.

[0179] Exemplarily, the above effective time range includes at least one of the following:

[0180] N PDCCH monitoring periods,

[0181] M time units;

[0182] The time range determined based on the third information and the fifth time offset value.

[0183] Wherein, the above third information includes at least one of the following:

[0184] The start position of the second time unit, where the second time unit is the first time unit of the radio frame or subframe where the PDCCH monitoring period is located;

[0185] The start position of the PDCCH monitoring period before adjustment;

[0186] The end position of the PDCCH monitoring period before adjustment;

[0187] The start position or end position of the PDCCH monitoring period corresponding to the first information;

[0188] The reception time of the first information.

[0189] For example, after the terminal adjusts the time domain position of PDCCH monitoring based on the adjustment information, it performs PDCCH monitoring according to the adjusted time domain position within N PDCCH monitoring periods.

[0190] For example, after the terminal adjusts the time domain position of PDCCH monitoring based on the adjustment information, it performs PDCCH monitoring according to the adjusted time domain position within M time units.

[0191] For example, after the terminal adjusts the time domain position of PDCCH monitoring based on the adjustment information, the terminal performs PDCCH monitoring according to the adjusted time domain position within the time range determined by the third information and the fifth time offset value.

[0192] It should be noted that the above fifth time offset value can be configured by the network-side device or can be according to protocol agreements.

[0193] In this way, the terminal can start based on the adjusted time domain position of PDCCH monitoring at the start effective time and perform PDCCH monitoring within the effective time range, so that the PDCCH monitoring can be continuously adjusted in real time according to the first information, perform PDCCH blind detection according to different PDCCH monitoring information, and further avoid power waste caused by the terminal still performing blind detection according to the original PDCCH monitoring information when the PDCCH changes.

[0194] Optionally, in the embodiments of the present application, in combination with Figure 3 , as Figure 6 shown, the method for determining PDCCH monitoring information provided by the embodiments of the present application further includes step A or step B or step C:

[0195] Step A: When the terminal obtains the first information, the terminal monitors the PDCCH based on the second PDCCH monitoring information.

[0196] Step B: When the terminal fails to obtain the first piece of information, the terminal monitors the PDCCH based on the first PDCCH monitoring information.

[0197] Step C: When the terminal obtains the first piece of information and the effective time range has passed, the terminal monitors the PDCCH based on the first PDCCH monitoring information.

[0198] In some embodiments of the present application, the terminal can determine, according to the specific situation of receiving the first piece of information, which PDCCH monitoring information the terminal uses for PDCCH blind detection.

[0199] It should be noted that the above Step A, Step B, and Step C are parallel solutions. Specifically, the process of the terminal performing the PDCCH blind detection operation can be: first execute Step 201 and Step 202, and then execute Step A or Step C; or, first execute Step B, then execute Step 201 and Step 202, and then execute Step A or Step C. The specific execution process is not limited in this application.

[0200] In this way, the terminal monitors the PDCCH only when necessary according to the changing PDCCH monitoring information, so as to reduce the number of PDCCH blind detections of the terminal, thereby reducing the power consumption of the terminal.

[0201] Each of the above method embodiments, or various possible implementation manners in each method embodiment, can be executed independently, or any two or more of them can be combined with each other. It can be specifically determined according to actual usage requirements, and this application embodiment does not limit this.
