[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 202410037142.9 filed in China on January 9, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a method, device, terminal and medium for determining PDCCH monitoring information. Background Art

[0004] In a wireless communication system, user equipment (UE) can obtain information such as the physical resource location and resource size of downlink control information (DCI) by blindly detecting the physical downlink control channel (PDCCH).

[0005] In the long term evolution (LTE) system, the terminal performs downlink channel estimation based on the cell specific reference signal (CRS), and then blindly detects in the search space based on the downlink channel estimation result. The search space for UE blind detection in LTE is composed of all or part of all control channel elements (CCE) 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.

[0006] However, because the terminal's search space configuration information is currently static, when the terminal performs blind detection on a candidate PDCCH based on the PDCCH monitoring information determined by the search space configuration information, the terminal needs to periodically use the same PDCCH monitoring information to perform blind detection on the candidate PDCCH. This may result in the terminal being unable to detect changes in the PDCCH in a timely manner, resulting in the terminal still consuming a large amount of power and computing resources to perform blind detection on these candidate PDCCHs.

[0027] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0028] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, 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 generally of the same type, and do not limit the number of objects, for example, the first object can be one or more. In addition, "or" in this application represents at least one of the connected objects. For example, "A or B" covers three options, namely, Option 1: including A but not including B; Option 2: including B but not including A; Option 3: including both A and B. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0029] The term "indication" in this application can be either a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.

[0030] The terms "at least one" and "at least one of" in this application refer to any one, any two, or a combination of more than two of the objects included. For example, at least one of a, b, and c can be represented by: "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" means two or more, and its meaning is similar to "at least one".

[0031] The following is an explanation of the technical terms involved in the technical solutions provided in the embodiments of this application:

[0032] 1) New Radio (NR) Search Space

[0033] In 5G NR, the UE needs to fully obtain the PDCCH's time-frequency domain resource configuration information before it can further demodulate the PDCCH. The current protocol design encapsulates information such as the PDCCH's frequency domain resource information and the number of orthogonal frequency division multiplex (OFDM) symbols occupied in the time domain into the Control Resource Set (CORESET), and encapsulates information such as the PDCCH starting OFDM symbol, monitoring period, and associated CORESET into the search space.

[0034] The search space can be considered to consist of a set of candidate PDCCHs that the UE needs to blindly detect. The PDCCH search space is divided into the Common Search Space (CSS) and the UE-Specific Search Space (USS). The CSS corresponds to a group of UEs, meaning that common control information for a group of UEs is sent via the CSS. The USS corresponds to a specific UE, and UE-specific scheduling information can be sent via the USS.

[0035] When detecting a PDCCH, the UE detects DCI on different candidate PDCCHs using a specific DCI format and RNTI. The resource location of a candidate PDCCH is determined by the starting position and aggregation level of the CCE (Control Resource Element). When detecting DCI, the UE does not know whether the base station has sent DCI, nor the aggregation level and starting position of the CCE used to send the DCI. Therefore, the UE needs to try each candidate PDCCH one by one. This process is called blind PDCCH detection.

[0036] Multiple search spaces (up to 10) can be configured within each BWP to set different search space types, match different service types and scenarios, or transmit different DCI formats. Each search space is associated with a control resource set (CORESET), and the type, period, and size of each search space can be configured independently. The parameters that need to be configured for the search space include:

[0037] The index ID of the search space (searchSpaceID);

[0038] The CORESET ID (controlResourceSetID) associated with the search space;

[0039] PDCCH monitoring period and offset value (monitoringSlotPeriodicityAndOffset), whose unit is slot, the UE determines the time slot for monitoring PDCCH based on this parameter;

[0040] Duration: the number of slots that need to be monitored continuously starting from the slot where each monitoring starts;

[0041] The monitoring pattern of PDCCH within a time slot (monitoringSymbolsWithinSlot) indicates the starting symbol position of PDCCH monitoring in each time slot through a 14-bit bitmap. Each bit corresponds to an OFDM symbol in the time slot. The value "1" indicates that the OFDM symbol corresponding to the bit is the starting position of monitoring;

[0042] nrofCandidates parameter, the search space includes aggregation level information and the number of candidate PDCCHs (PDCCH candidates) at each aggregation level, that is, the UE needs to blindly detect all PDCCH candidates corresponding to all configured aggregation levels;

[0043] The type of search space (searchSpaceType) and the scheduled DCI format (Format).

[0044] 2) For the subcarrier spacing (SCS) configuration μ, the number of slots in a system frame is expressed as To express, the PDCCH monitoring period corresponding to the above search space is k s Indicates that the offset value of the PDCCH monitoring time slot within the period is o s Then, for system frame n f Time slots in When it satisfies: In other words, the starting point of the PDCCH monitoring period in NR defaults to the first slot of frame-0, slot-0.

[0045] For example, as shown in Figure 1, assuming 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 CORESET time domain symbols associated with the search space is 2, and the symbol positions are 0 and 7. Then, under this configuration, based on slot-0 of the starting position frame-0, the UE determines each monitoring period and determines the slot position to be monitored in each monitoring period. That is, in Figure 1, the UE will monitor the candidate PDCCH on symbol 0-1 and symbol 7-8 of slot-5 of each monitoring period.

[0046] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) or other systems.

[0048] The following, in conjunction with the accompanying drawings, describes in detail the PDCCH monitoring information determination method, device, terminal and medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0049] FIG3 shows a flow chart of a method for determining PDCCH monitoring information provided by an embodiment of the present application. As shown in FIG3 , the method for determining PDCCH monitoring information may include the following steps 201 and 202:

[0050] Step 201: The terminal obtains first information.

[0051] In some embodiments of the present application, the first information is information received by the terminal from a network-side device.

[0052] In some embodiments of the present application, the first information is used to adjust initial search space configuration information of the terminal.

[0053] In some embodiments of the present application, the above-mentioned first information is carried by the first PDCCH sent in the first search space, or carried by a channel scheduled by the first PDCCH.

[0054] In some embodiments of the present application, the first search space is a search space corresponding to initial search space configuration information.

[0055] In some embodiments of the present application, the first search space includes at least one candidate PDCCH.

[0056] In some embodiments of the present application, the first PDCCH is determined by the terminal based on first PDCCH monitoring information.

[0057] Optionally, in some embodiments of the present application, before the terminal obtains the first information, the terminal determines the first PDCCH monitoring information based on the configuration parameters of the candidate PDCCH included in the initial search space configuration information, performs blind detection on 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. The terminal can then receive the first information on the first PDCCH, or receive the first information on the channel scheduled by the first PDCCH.

[0058] Exemplarily, when the first information is carried by the first PDCCH or carried by a channel scheduled by the first PDCCH, the first information may be carried in the first signaling.

[0059] Exemplarily, the first signaling may be DCI signaling, or may be Medium Access Control (MAC) signaling, or may be Radio Resource Control (RRC) signaling.

[0060] In one example, the network-side device may indicate the first information through RRC signaling, wherein the first information includes an adjusted value of the parameter configuration of the corresponding search space.

[0061] In one example, the network side device indicates to the terminal a set of values ​​corresponding to different configuration information in the search space configuration information through RRC signaling, and indicates or activates the value of one of the configuration information in the search space configuration information through MAC signaling or DCI signaling.

[0062] For example, the network side device configures the value set of the PDCCH monitoring period as {40, 80, 160} time slots for the terminal through RRC signaling, and indicates that the PDCCH monitoring period is 80 time slots through MAC CE signaling or DCI signaling.

[0063] In another example, the network side device configures multiple configuration information value combinations in the search space configuration information for the terminal through RRC signaling, and indicates or activates one of the configuration information value combinations in the search space configuration information through MAC signaling or DCI signaling.

[0064] For example, combination 1 and combination 2 are configured in the RRC signaling, where 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}, and one of the two combinations is activated for the terminal through MAC signaling or DCI signaling.

[0065] In some embodiments of the present application, the first information includes at least one adjustment information.

[0066] In some embodiments of the present application, the above-mentioned adjustment information corresponds to at least one search space configuration information.

[0067] In some embodiments of the present application, a correspondence rule between the above adjustment information and at least one search space configuration information is determined by a network-side device configuration or by a predefined rule.

[0068] It should be noted that each of the above adjustment information is an independent resource block, and each resource block is configured by the network side device. The size of each block can be determined according to the predefined setting size, or it can be determined according to the network side device configuration or implicitly determined by other parameters.

[0069] In some embodiments of the present application, the size of the above-mentioned first information in the first signaling is determined according to the number of search spaces or search space groups to be adjusted and the size of each adjustment information configured by the network side device, and is mapped to each resource block in the order of the search space or search space group ID, wherein the domain size corresponding to each search space or search space group ID is the size of each adjustment information.

[0070] For example, there are three search spaces {Search space-1, Search space-2, Search space-3}, and the first information includes three adjustment information blocks {Information block-1, Information block-2, Information block-3}, where the adjustment information blocks correspond to the search spaces in order of their IDs. Alternatively, each adjustment information block includes its associated search space or search space combination, so that the adjustment information blocks correspond to the search spaces or search space combinations in a one-to-one manner.

[0071] Step 202: The terminal adjusts the initial search space configuration information based on the first information to obtain second PDCCH monitoring information corresponding to the adjusted initial search space configuration information.

[0072] In some embodiments of the present application, the above-mentioned “adjusting the initial search space configuration information” may include at least one of the following: modifying the initial search space configuration information, and adding the initial search space configuration information.

[0073] In some embodiments of the present application, the terminal may adjust part or all of the content of the initial search space configuration information according to the first information, or add part of the content to the initial search space configuration information.

[0074] Optionally, in some embodiments of the present application, after acquiring the first information, the terminal adjusts the initial search space configuration information according to the adjustment information included in the first information to obtain an adjusted initial search space configuration.

[0075] It should be noted that the initial search space configuration information mentioned in the embodiments of this application refers to the search space configuration information before the terminal receives the first information adjustment. In other words, the initial search space configuration information can be the search space configuration information initially received by the terminal or the search space configuration information currently used by the terminal, and this application does not limit this.

[0076] In the PDCCH monitoring information determination method provided in an embodiment of the present application, a terminal obtains first information, and the first information 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 based on the obtained first information, so that the terminal can determine the new PDCCH monitoring information based on the adjusted search space configuration information, so that the terminal can more accurately monitor the candidate PDCCH when using the new PDCCH monitoring information for PDCCH blind detection, thereby reducing the power consumed by the terminal for PDCCH blind detection.

[0077] Optionally, in some embodiments of the present application, initial search space configuration information of the terminal is used to determine the first PDCCH monitoring information.

[0078] Optionally, in some embodiments of the present application, the first PDCCH monitoring information includes at least one of the following:

[0079] Time domain location of PDCCH monitoring;

[0080] Frequency domain location of PDCCH monitoring;

[0081] Aggregation level for PDCCH monitoring;

[0082] Candidate PDCCHs for PDCCH monitoring;

[0083] Downlink control information DCI format for PDCCH monitoring;

[0084] Position of candidate PDCCHs for PDCCH monitoring;

[0085] The starting monitoring position of the candidate PDCCH for PDCCH monitoring.

[0086] In some embodiments of the present application, the starting monitoring position of the candidate PDCCH for the PDCCH monitoring may include at least one of the following:

[0087] The starting monitoring positions of PDCCH candidates corresponding to different aggregation levels;

[0088] The starting PDCCH candidate monitoring position among all PDCCH candidates;

[0089] The default PDCCH candidate starting monitoring position is 1.

[0090] Optionally, in some embodiments of the present application, the configuration parameters regarding the time domain position of PDCCH monitoring in the initial search space configuration information include at least one of the following:

[0091] PDCCH monitoring period;

[0092] First time offset value;

[0093] first monitoring position indication information;

[0094] The number of consecutive time units used for PDCCH monitoring;

[0095] a second time offset value;

[0096] A PDCCH monitoring position for each sub-time unit in a time unit for PDCCH monitoring.

[0097] In some embodiments of the present application, the above-mentioned PDCCH monitoring period can be indicated in a time unit granularity, such as a time slot, a sub-time slot, a frame or a subframe.

[0098] It is understandable that the above-mentioned PDCCH monitoring period may be a period consisting of 10 time slots as a group, or a period consisting of 15 time slots as a group.

[0099] In some embodiments of the present application, the first time offset value is used to determine a monitoring position in a PDCCH monitoring period.

[0100] In some embodiments of the present application, after receiving the first information including the first time offset value, the terminal determines the time domain position after the first time offset value in a certain PDCCH monitoring period as the monitoring position.

[0101] In some embodiments of the present application, the first monitoring position indication information is used to indicate whether each time unit in the PDCCH monitoring period needs to be monitored.

[0102] In some embodiments of the present application, the first monitoring position indication information may be a bitmap sequence or a binary sequence. If the first monitoring position indication information is a bitmap sequence, the position of a "1" in the bitmap sequence indicates that the time unit corresponding to that position needs to be monitored. If the first monitoring position indication information is a binary sequence, the decimal number of the binary sequence indicates which time unit in the PDCCH monitoring period needs to be monitored.

[0103] For example, taking the PDCCH monitoring period as 10 slots, if the bitmap sequence is a 10-bit sequence 0001100000, it means that the terminal monitors the 4th and 5th slots in the PDCCH monitoring period.

[0104] Example 1, as shown in FIG4, the configuration information of the search space SearchSpace-1 configured initially includes: PDCCH monitoring period T default , that is, the PDCCH monitoring period mentioned above, the starting position of the monitoring period is the time offset time_offset relative to the first time slot of frame-0 default , that is, the second time offset value mentioned above, the bitmap indicating whether each time unit is monitored during the monitoring period default , that is, the first monitoring position indication information is a bitmap sequence as an example. PDCCH monitoring period T default The unit is 20 time slots, and the monitoring period start position offset is 5 time slots. The time slots that the terminal needs to monitor are indicated by a bitmap with time slot as the granularity. Starting from each time slot that starts monitoring, the number of time slots that need to be continuously monitored is 1. Assuming the bitmap default is [01010011101011010100], then it can be concluded that the time slots that need to be monitored are: the 7th, 9th, 12th, 13th, 14th, 16th, 18th, 19th, 21st and 23rd time slots, which are the shaded parts in Figure 4.

[0105] In some embodiments of the present application, the number of continuous time units for PDCCH monitoring may be indicated in a time unit granularity, such as a time slot, a sub-time slot, a frame, or a sub-frame.

[0106] In some embodiments of the present application, the second time offset value is used to determine the starting position of the PDCCH monitoring period.

[0107] In some embodiments of the present application, the second time offset value is a time offset value of the PDCCH monitoring period relative to the radio frame or radio subframe in which the monitoring period is located.

[0108] In some embodiments of the present application, after the terminal receives the second time offset value included in the first information, the terminal determines the starting position of the PDCCH monitoring period in the radio frame or radio subframe according to the second time offset value.

[0109] In some embodiments of the present application, the sub-time unit in the PDCCH monitoring position of each sub-time unit in the time unit for PDCCH monitoring may be an OFMD symbol.

[0110] Optionally, in some embodiments of the present application, the second PDCCH monitoring information includes at least one of the following:

[0111] Time domain location of PDCCH monitoring;

[0112] Frequency domain location of PDCCH monitoring;

[0113] Aggregation level for PDCCH monitoring;

[0114] Candidate PDCCHs for PDCCH monitoring;

[0115] Downlink control information DCI format for PDCCH monitoring;

[0116] Position of candidate PDCCHs for PDCCH monitoring;

[0117] The starting monitoring position of the candidate PDCCH for PDCCH monitoring.

[0118] In some embodiments of the present application, the starting monitoring position of the candidate PDCCH for the PDCCH monitoring may include at least one of the following:

[0119] A) PDCCH candidate starting monitoring positions corresponding to different aggregation levels;

[0120] B) the starting PDCCH candidate monitoring position among all PDCCH candidates;

[0121] C) The default PDCCH candidate starting monitoring position is 1.

[0122] Example 2: The aggregation levels monitored by the PDCCH and the number of PDCCH candidates corresponding to each aggregation level included in the search space SearchSpace-1 configuration information are:

[0123] aggregationLevel1:n8,

[0124] aggregationLevel2: n6,

[0125] aggregationLevel4:n4,

[0126] aggregationLevel8:n2,

[0127] aggregationLevel16:n2.

[0128] For A), if the network side device configuration corresponds to the aggregation level {1,2,4,8,16} and the PDCCH candidate starting monitoring position is {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 blind detection from the 5th PDCCH candidate. For aggregationLevel2, it only needs to start blind detection from the 3rd PDCCH candidate.

[0129] For B), if the network side configures the starting monitoring position for all PDCCH candidates corresponding to all aggregation levels, all PDCCH candidates, that is, 22 PDCCH candidates, are first sorted according to the aggregation level, and then the PDCCH candidate to start blind detection is determined based on the configured PDCCH candidate starting monitoring position. For example, if the PDCCH candidate starting monitoring position is configured as 21, then the terminal only needs to start blind detection from the 21st PDCCH candidate, that is, from the first PDCCH candidate corresponding to aggregationLevel16.

[0130] In this way, the terminal can perform blind detection on a specific PDCCH according to the configured starting monitoring position, and does not need to perform blind detection on all PDCCHs, thereby reducing the number of blind detections and thus reducing the power of the terminal performing PDCCH blind detection.

[0131] Optionally, in some embodiments of the present application, each adjustment information included in the first information includes at least one of the following:

[0138] Adjustment information of candidate PDCCH start monitoring positions for PDCCH monitoring;

[0139] Position adjustment information of candidate PDCCHs for PDCCH monitoring;

[0140] Newly added PDCCH monitoring information.

[0141] In some embodiments of the present application, if the above-mentioned 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 can be any one or more of the candidate PDCCH for PDCCH monitoring, the downlink control information DCI format for PDCCH monitoring, the position of the candidate PDCCH for PDCCH monitoring, or the starting monitoring position of the candidate PDCCH for PDCCH monitoring.

[0142] In some embodiments of the present application, the adjustment information of the candidate PDCCH start monitoring position for PDCCH monitoring includes at least one of the following:

[0143] The adjusted starting monitoring positions of PDCCH candidates corresponding to different aggregation levels;

[0144] The adjusted PDCCH candidate start monitoring position among all PDCCH candidates.

[0145] Second time offset adjustment information, where the second time offset adjustment information is used to indicate an adjusted starting position of the PDCCH monitoring period;

[0146] a third time offset value of the start monitoring position of the adjusted PDCCH monitoring period relative to the start monitoring position of the PDCCH monitoring period before the adjustment.

[0147] Example 3, combined with Example 2, taking the adjusted PDCCH candidate starting monitoring position among all PDCCH candidates as an example, for Search Space-1, the initial PDCCH candidate starting monitoring position corresponding to the aggregation level {1, 2, 4, 8, 16} is {5, 3, 2, 1, 1}. The first information can adjust the PDCCH candidate starting monitoring position corresponding to the aggregation level 1 from 5 to 2, and the PDCCH candidate starting monitoring positions corresponding to other aggregation levels remain unchanged. Then, the adjusted PDCCH candidate starting monitoring position corresponding to the aggregation level {1, 2, 4, 8, 16} is {2, 3, 2, 1, 1}.

[0148] In some embodiments of the present application, the adjustment information of the time domain position for PDCCH monitoring includes at least one of the following:

[0149] PDCCH monitoring period adjustment information;

[0150] First time offset adjustment information;

[0151] second monitoring position indication information;

[0152] The number of consecutive time units for PDCCH monitoring that needs to be adjusted;

[0153] Adjustment information of the starting position of the PDCCH monitoring period;

[0154] an adjusted PDCCH monitoring position of a sub-time unit in a time unit for PDCCH monitoring;

[0155] The effective time information of the adjusted time domain position used for PDCCH monitoring includes the effective start time and the effective time range.

[0156] Exemplarily, the adjustment information of the PDCCH monitoring period may be indicated in a time unit granularity, such as a time slot, a sub-time slot, a frame or a sub-frame, etc. For example, the PDCCH monitoring period is adjusted to 10 slots.

[0157] Exemplarily, the first time offset adjustment information is used to indicate an adjustment position of a first time offset value, wherein the first time offset value refers to the description of the first time offset value in the first PDCCH monitoring information, which is not repeated here.

[0158] Exemplarily, the second monitoring position indication information is used to indicate whether each adjusted time unit in each PDCCH monitoring period needs to be monitored.

[0159] Example 4, combined with Example 1 (refer to FIG4), as shown in FIG5, for example, if the first information instructs the terminal to set the PDCCH monitoring period T in the SearchSpace-1 configuration information default Adjust to T adjust , time offset time_offset default Remain unchanged, the bitmap indicating whether each time unit is monitored during the PDCCH monitoring period default Adjust to bitmap adjust For example, T adjust 30 slots, bitmap adjust =[111100101001010000001001010000], then the corresponding time slots that need to be monitored are: the 6th to 9th, 12th, 14th, 17th, 19th, 26th, 29th and 31st time slots, that is, the shaded parts in Figure 5.

[0160] Exemplarily, the number of continuous time units for PDCCH monitoring that needs to be adjusted may be indicated in a time unit granularity, such as a time slot, a sub-time slot, a frame, or a sub-frame.

[0161] Exemplarily, the “effective time information” in the effective time information of the adjusted time domain position for PDCCH monitoring includes the effective start time and the effective time range.

[0162] Exemplarily, the above-mentioned effective start time is the time when the terminal starts to perform PDCCH monitoring at the adjusted time domain position of the PDCCH based on the second PDCCH monitoring information.

[0163] For example, the effective start time is determined based on at least one of the following:

[0164] The end monitoring position of the PDCCH monitoring period,

[0165] The time of receipt of the first message,

[0166] The end position of the PDCCH monitoring period corresponding to the first information;

[0167] second information and a fourth time offset value.

[0168] Exemplarily, the above-mentioned “PDCCH monitoring period corresponding to the first information” refers to the monitoring period corresponding to the PDCCH that carries or schedules the first information.

[0169] The second information includes at least one of the following:

[0170] The starting position of the first time unit, where the first time unit is the first time unit of the radio frame or subframe where the PDCCH monitoring period is located;

[0171] The starting position of the PDCCH monitoring period before adjustment;

[0172] The end position of the PDCCH monitoring period before adjustment;

[0173] The starting position or ending position of the PDCCH monitoring period corresponding to the first information;

[0174] The time when the first message was received.

[0175] 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.

[0176] For example, when the second information includes the start position of the PDCCH monitoring period before adjustment, the terminal determines the effective start 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.

[0177] For example, when the second information includes the end position of the PDCCH monitoring period before adjustment, the terminal determines the effective start 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.

[0178] For example, when the second information includes the reception time of the first information, the terminal determines the start time of effectiveness based on 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.

[0179] It should be noted that the fourth time offset value may be configured by the network side device or agreed upon by the protocol.

[0180] Exemplarily, the above-mentioned effective time range is a time range in which the terminal performs PDCCH monitoring at the adjusted time domain position of the PDCCH based on the second PDCCH monitoring information.

[0181] Illustratively, the effective time range includes at least one of the following:

[0182] N PDCCH monitoring periods,

[0183] M time units;

[0184] A time range is determined based on the third information and the fifth time offset value.

[0185] The third information includes at least one of the following:

[0186] a start position of a second time unit, where the second time unit is the first time unit of a radio frame or subframe in which the PDCCH monitoring period is located;

[0187] The starting position of the PDCCH monitoring period before adjustment;

[0188] The end position of the PDCCH monitoring period before adjustment;

[0189] The starting position or ending position of the PDCCH monitoring period corresponding to the first information;

[0190] The time when the first message was received.

[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 in N PDCCH monitoring periods.

[0192] For example, after the terminal adjusts the time domain position for PDCCH monitoring based on the adjustment information, the terminal performs PDCCH monitoring according to the adjusted time domain position within M time units.

[0193] 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.

[0194] It should be noted that the fifth time offset value may be configured by the network side device or may be agreed upon according to a protocol.

[0195] In this way, the terminal can start the time domain position based on the adjusted PDCCH monitoring at the start 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, so as to perform PDCCH blind detection according to different PDCCH monitoring information, thereby avoiding power waste caused by the terminal still performing blind detection according to the original PDCCH monitoring information when the PDCCH changes.

[0196] Optionally, in an embodiment of the present application, in combination with FIG3 , as shown in FIG6 , the method for determining PDCCH monitoring information provided in an embodiment of the present application further includes step A or step B or step C:

[0197] Step A: When the terminal obtains the first information, the terminal monitors the PDCCH based on the second PDCCH monitoring information.

[0198] Step B: When the terminal does not obtain the first information, the terminal monitors the PDCCH based on the first PDCCH monitoring information.

[0199] Step C: When the terminal obtains the first information and the effective time range has expired, the terminal monitors the PDCCH based on the first PDCCH monitoring information.

[0200] In some embodiments of the present application, the terminal may determine, based on the specific circumstances of receiving the first information, which PDCCH monitoring information the terminal uses to perform PDCCH blind detection.

[0201] It should be noted that the above steps A, B, and C are parallel solutions. Specifically, the process of the terminal performing the PDCCH blind detection operation can be: first performing steps 201 and 202, then performing step A or step C; or first performing step B, then performing steps 201 and 202, and then performing step A or step C. The specific execution process is not limited in this application.

[0202] In this way, the terminal monitors the PDCCH only when needed according to the changed PDCCH monitoring information, thereby reducing the number of PDCCH blind detections of the terminal and thus reducing the power consumption of the terminal.

[0203] Each of the above-mentioned method embodiments, or various possible implementation methods in each method embodiment, can be executed separately, or any two or more of them can be executed in combination with each other. The specific implementation can be determined according to actual usage requirements, and the embodiments of this application do not limit this.
