Furthermore, the symbol " / " herein generally indicates that the associated objects before and after are in an "or" relationship.

[0024] In order to more fully understand the features and technical content of the embodiments of the present invention, the following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, which are for reference purposes only and are not intended to limit the embodiments of the present invention.

[0025] An embodiment of the present invention provides a signal monitoring method, as shown in FIG. 2-1, the method includes the following steps:

[0026] In step 21, the terminal device monitors the energy saving signal PDCCH in a monitoring period before the discontinuous reception (DRX) ON period and after the monitoring start time; Wherein the monitoring period is determined by at least one configuration parameter of each of the K energy-saving signal search spaces, where K is an integer greater than or equal to 1.

[0027] Correspondingly, an embodiment of the present invention further provides a signal transmission method, as shown in FIG. 2-2, the method includes the following steps:

[0028] In step 31, the network device transmits an energy saving signal physical downlink control channel (PDCCH) in a monitoring period before a discontinuous reception (DRX) ON period and after a monitoring start time; Wherein the monitoring period is determined by at least one configuration parameter of each of the K energy-saving signal search spaces, where K is an integer greater than or equal to 1.

[0029] The energy-saving signal search space is a PDCCH search space. Specifically, in New Radio (NR), a terminal device monitors a downlink physical control channel (PDCCH) in a PDCCH search space. The configuration parameters of the PDCCH search space are usually notified to the terminal device by a network device via RRC signaling.

[0030] Regarding the description related to the energy saving signal PDCCH, the energy saving signal PDCCH can be used not only to wake up the terminal device to detect the PDCCH, but also to indicate energy saving indication information such as the target bandwidth part (BWP) to be used when waking up the terminal device, the configuration of the PDCCH search space to be used, and secondary cell dormancy indication information.

[0031] Here, the energy saving signal is Downlink Control Information (DCI) carried on the PDCCH, for example, the energy saving signal is DCI format 3_0.

[0032] It should be noted that employing PDCCH to carry energy-saving signals has the following advantages:

[0033] 1. The PDCCH design can be directly reused, including aspects such as coding, scrambling, resource mapping, search space, and control resource set (CORESET), thus reducing the standardization workload.

[0034] 2. It has good compatibility and reuse characteristics for transmission with other signals. Since the system supports the PDCCH channel, it has good compatibility and reuse characteristics with the PDCCH and other channels such as the Physical Downlink Shared Channel (PDSCH).

[0035] Regarding the monitoring start time, the terminal device can determine the monitoring start time based on a configured power saving (PS)-offset and the start time of the DRX ON period.

[0036] Specifically, the configured PS-Offset may be configured in the terminal device by the network device via RRC signaling, or may be predefined. Determining the monitoring start time based on the start time of the DRX ON period and the PS-Offset may specifically involve using the time obtained by subtracting the PS-Offset from the start time of the DRX ON period as the monitoring start time.

[0037] For example, referring to Figure 3-1, taking one DRX ON on the left side of the drawing as an example, the start time of the DRX ON period is used as the reference time, and one PS-Offset is subtracted to obtain the monitoring start time of the PDCCH monitoring period.

[0038] The DRX ON period is a period from when the terminal starts a DRX "ON duration" timer at the start position of the DRX cycle to when the timer ends or times out. For example, referring to Figure 3-1, it is shown that within a block, one DRX ON coverage area on the time axis can be a DRX ON period.

[0039] This embodiment can be applied to a scenario in which one energy-saving signal search space is configured in a terminal device, and can also be applied to a scenario in which multiple energy-saving signal search spaces are configured in a terminal device. The technical solution according to this embodiment will be described with reference to several examples.

[0040] In Example 1, K=1, that is, one energy-saving signal search space is configured in the terminal device.

[0041] In this example, the monitoring period includes M durations of each of the K energy-saving signal search spaces, where M is an integer greater than or equal to one.

[0042] This example is for a scenario where K=1, so the monitoring period in this example includes M durations for the constructed energy-saving signal search space.

[0043] The above M may be configured or predefined, where if M is configured, the terminal device may receive M configured for the terminal device by a network device, specifically, may convey the M value via Radio Resource Control (RRC) signaling. Preferably, M=1.

[0044] Furthermore, in this example, when a monitoring period includes M durations, the length of the monitoring period may be equal to the sum of the M durations, or the length of the monitoring period may be greater than the sum of the M durations. In this case, it should be noted that the monitoring period may include the interval between adjacent durations in addition to the length of each duration, or may include other periods other than durations, etc.

[0045] Each duration of the M durations includes at least one monitoring time instant.

[0046] The terminal device may determine a corresponding monitoring period based on at least one configuration parameter of an energy-saving signal search space, where the at least one configuration parameter in the energy-saving signal search space, i.e., PDCCH search space, is: a first parameter for indicating the number of slots to be continuously monitored within a period of the corresponding energy-saving signal search space; The at least one second parameter may include at least one for indicating a starting symbol of a monitoring time of the energy saving signal PDCCH in the corresponding energy saving signal search space.

[0047] Here, the first parameter may be a "Duration" parameter in the PDCCH Search Space, and the second parameter may be a "monitoringSymbolsWithinSlot" parameter in the PDCCH Search Space.

[0048] For example, the length of one duration can be determined based on a first parameter, and a second parameter can be used to determine from which starting symbol monitoring begins.

[0049] Specifically, the first parameter can determine how many slots each duration includes, and the second parameter can include a bitmap that indicates the start symbol of each monitoring time. In other words, the number of monitoring times can be determined via the bitmap. For example, if the bitmap indicates "1001001," the first symbol represents one monitoring time, the fourth symbol represents the start symbol of one monitoring time, and the seventh symbol represents the start symbol of one monitoring time. Furthermore, the CORESET can determine how many monitoring times each start symbol corresponds to, for example, two monitoring times from the first start symbol, two monitoring times from the fourth symbol, etc.

[0050] Furthermore, in addition to the above-mentioned first and second parameters, the configuration parameters in the energy-saving signal search space may include, for example, a search identifier (search ID), a controlResourceSetId indicating the ID of the configuration of a control resource set and used to configure the time-frequency resources of the PDCCH search space, the period of the monitoring slot and the offset within the period, configuration information of PDCCH candidates, and an indication of the type of search space. Note that other parameters may also be present, and the search space type may include a PDCCH search space, a common search space, and a UE-specific space. Of course, other configuration parameters may also be present, and this example does not provide an exhaustive list.

[0051] In this example, the at least one monitoring time may be all the monitoring time in one duration, or may be a portion of the monitoring time in one duration.

[0052] Referring to FIG. 3-1, in this example, all monitoring times are included in the duration, and M=2, i.e., an example of two durations. Specifically, each duration is one complete duration, that is, all PDCCH monitoring times within the duration are within the determined PDCCH monitoring period. The terminal device monitors the PDCCH at the PDCCH monitoring times within the two "durations," starting from the PDCCH monitoring start position obtained based on PS_offset. At the PDCCH monitoring times indicated by dotted lines in FIG. 3-1, the terminal does not monitor the PDCCH. Furthermore, for simplicity, FIG. 3-1 does not show PDCCH monitoring positions for all PDCCH search space periods, but only shows some of the PDCCH monitoring positions before DRX ON as an example. This does not mean that the monitoring positions corresponding to the monitoring times are limited to the positions shown in the drawing.

[0053] Referring to FIG. 3-2, M=2, i.e., an example of two durations. In this example, the duration includes a portion of the monitoring time, i.e., includes an incomplete duration, but includes at least one PDCCH monitoring time. For example, the duration truncated by the parameter PS_offset can be counted as one duration. As shown in FIG. 3-2 below, M=2. The terminal monitors the PDCCH starting from the start position of PDCCH monitoring obtained based on PS_offset, where the first duration is monitored only at the PDCCH monitoring time after the start monitoring time indicated by PS_offset. The monitoring times corresponding to the shaded symbols in the figure are outside the monitoring period, so monitoring of the energy saving signal PDCCH is not performed at the corresponding times.

[0054] In a preferred example, at least one of the above monitoring times must be a valid monitoring time.

[0055] For effective monitoring times, see the following explanation for the definition of effective rules.

[0056] When a terminal device (e.g., a New Radio (NR) terminal) operates in a single-cell operation or carrier aggregation state, and PDCCH monitoring times in PDCCH CORESETs with the same quasi-co-location (QCL)-Type D attribute monitored by the terminal device in an activated bandwidth part (BWP) in one or more cells overlap, the terminal device monitors the energy-saving signal PDCCH only at the monitoring time of one COESET in the activated BWP in the one or more cells, or the terminal device monitors the energy-saving signal PDCCH in any other CORESET with the same QCL-Type D attribute as the CORESET, where the CORESET satisfies the following condition:

[0057] CORESET contains the CSS set of the lowest indexed cells in the CSS, If CORESET does not include a CSS set of the lowest index of the lowest index cell among the cells of the CSS, the CORESET includes a USS set of the lowest index of the lowest index cell corresponding to the USS.

[0058] Here, the index of the USS set with the smallest index is determined from all USS sets in which at least one PDCCH candidate is included in the overlapping PDCCH monitoring times.

[0059] Furthermore, the following definition is included: One SS / PBCH block is considered to have a different QCL-typeD attribute from one CSI-RS; A CSI-RS associated with one SS / PBCH block in a first cell and a second CSI-RS associated with the same SS / PBCH block in a second cell are considered to have the same QCL-Type D attribute.

[0060] Conversely, if a terminal device is operated in single-cell operation or carrier aggregation operation and is configured to monitor PDCCHs at multiple overlapping PDCCH CORESTs that do not have QCL-TypeD attributes, the terminal needs to monitor PDCCHs at PDCCH monitoring times corresponding to the above CORESETs at the overlapping PDCCH monitoring times, that is, in this case, all monitoring times corresponding to the above CORESETs may be valid monitoring times.

[0061] See the above description of validity, that is, a duration that includes at least one valid monitoring time can be counted as one duration.

[0062] Further, referring to a preferred example of validity, if a particular duration does not include a valid monitoring time, the duration can be considered not to be counted, and the next duration can be further determined to include at least one valid monitoring time to determine whether the next duration has been counted, and this process is repeated until all durations within the current monitoring period have been completed.

[0063] In Example 2, the difference from Example 1 is that it explains the case where K>1, that is, it is a technical proposal for configuring multiple energy-saving signal search spaces in the terminal to monitor PDCCH-based energy-saving signals (i.e., energy-saving signals PDCCH).

[0064] The technical solution of this example is that the terminal device determines M durations within the monitoring period corresponding to each energy-saving signal search space among the K energy-saving signal search spaces (specifically, PDCCH search spaces) based on at least one configuration parameter corresponding to each energy-saving signal search space.

[0065] As in Example 1, the above M may be configured or predefined. Here, if M is configured, the terminal device may receive M configured for the terminal device by a network device, specifically, the M value may be conveyed via Radio Resource Control (RRC) signaling. Preferably, M=1.

[0066] The difference from Example 1 is that when K is greater than 1, there are multiple energy-saving signal search spaces, that is, the final monitoring period contains K*M durations.

[0067] Furthermore, it should be noted that among the above K*M durations, the durations of different energy-saving signal search spaces may overlap, and thus a total duration can be determined based on the K*M durations. For example, among two energy-saving signal search spaces, a first energy-saving signal search space includes four durations and corresponds to slots 1, 3, 5, and 7, and a second energy-saving signal search space includes four durations and corresponds to slots 3, 5, 7, and 9. Then, a total duration can be determined, where the start time may be the start time of slot 1 and the end time may be the end time of slot 9.

[0068] Of course, if the monitoring times of the durations of different energy-saving signal search spaces do not overlap, the monitoring period can be considered to include K*M durations, or one total duration can be determined according to the K*M durations. For example, if the duration included in the first energy-saving signal search space corresponds to slots 1 and 3, and the duration included in the second energy-saving signal search space corresponds to slots 2 and 4, the monitoring period can be considered to include slots 1, 2, 3, and 4, or the monitoring period can be considered to include one duration, with the start time being the start time of slot 1 and the end time being the end time of slot 4.

[0069] In this example, the method for determining the M durations in each energy-saving signal search space is the same as in Example 1, and further, the related explanations, such as that each duration in each energy-saving signal search space includes at least one monitoring time (or at least one valid monitoring time), are also the same as in Example 1, and therefore will not be repeated in this example.

[0070] In Example 3, the case where K>1 is also described, that is, a technical solution in which multiple energy-saving signal search spaces are configured in a terminal to monitor a PDCCH-based energy-saving signal (i.e., energy-saving signal PDCCH).

[0071] The difference from Example 2 is that in this example, the monitoring period includes M durations, where M is an integer greater than or equal to 1. That is, all K energy-saving signal search spaces correspond to the same M durations, for example, when M=1, all K energy-saving signal search spaces adopt the same one duration.

[0072] wherein the length of each of the M durations is: the length of the longest duration of at least one of the durations of the K energy-saving signal search spaces; Preset time length, a preset multiple of the longest duration of at least one of the durations of the K energy-saving signal search spaces; It can be one of a preset multiple of a preset length of time.

[0073] Specifically, the length of the longest duration among the durations of at least one of the K energy-saving signal search spaces is This may include first determining the duration length of each energy-saving signal search space based on at least one configuration parameter of each energy-saving signal search space, and then selecting the longest duration length from a plurality of durations corresponding to the K energy-saving signal search spaces to use as the duration length finally adopted in this example.

[0074] Here, the method of determining the duration length based on at least one configuration parameter of each energy-saving signal search space is the same as in Example 1 above, and will not be repeated here. Correspondingly, the method of determining at least one monitoring time after determining the duration is also the same as in Example 1 above, and will not be repeated here.

[0075] In the preset multiple of the longest duration among at least one duration of the K energy-saving signal search spaces, the preset multiple may be predefined or may be notified to the terminal equipment by the network equipment via RRC signaling, for example, when N=2, the length of each duration of the finally determined M durations is twice the above-determined longest duration.

[0076] Furthermore, the above-mentioned preset time length may be predefined (e.g., protocol-defined or default value), or may be conveyed by the network equipment via RRC and notified to the terminal equipment. Regarding the preset multiple of the preset time length, here, the preset multiple may be predefined or may be notified by the network equipment to the terminal equipment via RRC signaling.

[0077] The relevant explanations, such as that each duration in this example includes at least one monitoring time (or at least one valid monitoring time), are the same as in Example 1, and therefore will not be repeated in this example.

[0078] In Example 4, K=1, that is, an energy-saving signal search space is configured in the terminal device.

[0079] Different from all the above examples 1 to 3, in this example, the monitoring period includes N monitoring times in each of the K energy-saving signal search spaces, where N is an integer greater than or equal to 1.

[0080] In this example, K=1, so the monitoring period in this example includes N monitoring times of one configured energy-saving signal search space.

[0081] The above N may be configured or predefined, where if N is configured, the terminal device may receive N configured for the terminal device by the network device, and in particular may convey the N value via Radio Resource Control (RRC) signaling.

[0082] The terminal device may determine N corresponding monitoring times based on at least one configuration parameter of an energy-saving signal search space, where the at least one configuration parameter in the energy-saving signal search space, i.e., PDCCH search space, is: a first parameter for indicating the number of slots to be continuously monitored within a period of the corresponding energy-saving signal search space; The at least one second parameter may include at least one for indicating a starting symbol of a monitoring time of the energy saving signal PDCCH in the corresponding energy saving signal search space.

[0083] Here, the first parameter may be a "Duration" parameter in the PDCCH Search Space, and the second parameter may be a "monitoringSymbolsWithinSlot" parameter in the PDCCH Search Space.

[0084] Specifically, the length of one duration can be determined based on a first parameter, and a second parameter can be used to determine from which starting symbol monitoring should begin.

[0085] Furthermore, the second parameter may include a bitmap, which may indicate the start symbol of each monitoring time. In other words, the number of monitoring times may be determined via the bitmap. For example, if the bitmap indicates "1001001," the first symbol represents one monitoring time, the fourth symbol represents one monitoring time, and the seventh symbol represents one monitoring time. Furthermore, via CORESET, it may be determined how many monitoring times each start symbol corresponds to, for example, two monitoring times from the first start symbol, two monitoring times from the fourth symbol, etc.

[0086] Referring to FIG. 3-3, taking N=4 as an example, the monitoring period includes N monitoring times. The terminal device starts monitoring the PDCCH from the monitoring start time of the monitoring PDCCH obtained based on PS_offset until it completes monitoring the PDCCH at N=4 PDCCH monitoring times.

[0087] In a preferred example, in the above at least one monitoring time, each monitoring time must be a valid monitoring time, where the definition of validity within a valid monitoring time is the same as in Example 1, and will not be repeated.

[0088] Referring to Figure 3-4, the monitoring times corresponding to the gray symbols in Figure 3-4 are invalid monitoring times or monitoring times outside the monitoring period. Taking N=4 as an example, the first PDCCH monitoring position after the start position of the monitoring PDCCH obtained by PS_offset is a valid PDCCH monitoring position, but the second PDCCH monitoring position is an invalid monitoring time. Therefore, the terminal needs to monitor up to the fifth monitoring time after the start position of the monitoring PDCCH obtained by PS_offset to obtain N=4 valid monitoring times.

[0089] Example 5 differs from Example 4 in that it describes the case where K>1, that is, a technical solution when multiple energy-saving signal search spaces are configured in the terminal to monitor a PDCCH-based energy-saving signal (i.e., energy-saving signal PDCCH).

[0090] The technical solution of this example is that the terminal device determines N monitoring times within a monitoring period corresponding to each energy-saving signal search space among the K energy-saving signal search spaces (specifically, PDCCH search spaces) based on at least one configuration parameter corresponding to each energy-saving signal search space.

[0091] As in Example 4, N above can be configured or predefined.

[0092] The difference from Example 1 is that when K is greater than 1, there are multiple energy-saving signal search spaces, that is, the final monitoring period includes K*N monitoring times.

[0093] In this example, the method for determining the N monitoring times in each energy-saving signal search space is the same as in Example 4, and the related explanations, such as the N monitoring times being valid monitoring times, are also the same as in Example 4, so they will not be repeated in this example.

[0094] In Example 6, the case where K>1 is also described, that is, a technical solution in which multiple energy-saving signal search spaces are configured in a terminal to monitor a PDCCH-based energy-saving signal (i.e., energy-saving signal PDCCH).

[0095] The difference from Example 5 is that in this example, the monitoring period includes N monitoring times. That is, regardless of how many energy-saving signal search spaces there are, all of them use the same N monitoring times for monitoring. Here, the method of determining the N monitoring times may be to randomly select N monitoring times (or N valid monitoring times) within a monitoring period in any one energy-saving signal search space, or to select a portion (one or more) within each monitoring period in two or more energy-saving signal search spaces and finally combine the N monitoring times. Of course, other methods may exist, but an exhaustive list will not be provided here.

[0096] In Example 7, Unlike all the above examples, in this example, the monitoring period includes L monitoring slots in each of the K energy-saving signal search spaces, where L is an integer greater than or equal to 1.

[0097] The monitoring period in this example includes L monitoring slots of one energy-saving signal search space that is configured. Alternatively, when K is greater than 1, L monitoring slots are similarly determined for each energy-saving signal search space, and finally, the monitoring period includes K*L monitoring slots.

[0098] The above L may be configured or predefined, where if L is configured, the terminal equipment may receive L configured for the terminal equipment by the network equipment, and in particular may convey the L value via Radio Resource Control (RRC) signaling.

[0099] The terminal device may determine the corresponding L monitoring slots based on at least one configuration parameter of an energy-saving signal search space, where the at least one configuration parameter in the energy-saving signal search space, i.e., PDCCH search space, is: a first parameter for indicating the number of slots to be continuously monitored within a period of the corresponding energy-saving signal search space; The at least one second parameter may include at least one for indicating a starting symbol of a monitoring time of the energy saving signal PDCCH in the corresponding energy saving signal search space.

[0100] Here, the first parameter may be a "Duration" parameter in the PDCCH Search Space, and the second parameter may be a "monitoringSymbolsWithinSlot" parameter in the PDCCH Search Space.

[0101] The first parameter can determine the number of slots included in one duration, and the second parameter can be used to determine from which starting symbol monitoring begins.

[0102] Furthermore, the second parameter may include a bitmap, which may indicate the start symbol of each monitoring time. In other words, the number of monitoring times may be determined via the bitmap. For example, if the bitmap indicates "1001001," from the first symbol, the fourth symbol may also be considered to be a start symbol, and the seventh symbol may also be considered to be a start symbol. In this way, multiple monitoring slots may be further determined based on the determined start symbols.

[0103] Referring to FIG. 3-3, taking L=2 as an example, the monitoring period includes L monitoring slots. The terminal device starts monitoring the PDCCH from the monitoring start time of the monitoring PDCCH obtained based on PS_offset until it completes monitoring the energy saving signal PDCCH within N=2 monitoring slots.

[0104] In a preferred example, the monitoring times included in the above L monitoring slots must be valid monitoring times. Here, the definition of validity within a valid monitoring time is the same as in Example 1, and will not be repeated. Furthermore, if the monitoring time included in a specific monitoring slot is invalid, the monitoring slot may not be counted.

[0105] Referring to Figure 3-5, the monitoring times corresponding to the gray symbols in Figure 3-5 are invalid monitoring times or monitoring times outside the monitoring period. Taking L=2 as an example, if there is one invalid monitoring time in the first monitoring slot after the start position of the monitoring PDCCH obtained by PS_offset, the terminal equipment needs to monitor up to the third monitoring slot to obtain L=2 monitoring slots, since the counting starts from the second monitoring slot.

[0106] Example 8 differs from Example 7 in that the monitoring period includes L monitoring slots. That is, regardless of the number of energy-saving signal search spaces, all of them employ the same L monitoring slots for monitoring. Here, the method for determining the L monitoring slots may be to randomly select L monitoring slots (or N valid monitoring times) within the monitoring period in any one energy-saving signal search space, or to select a portion (one or more) within each monitoring period in two or more energy-saving signal search spaces and finally combine the L monitoring slots. Of course, other methods may exist, but an exhaustive list will not be provided here.

[0107] In Example 9, Based on the above examples, this example further includes adding a third parameter, and the terminal device adjusting the monitoring period based on the third parameter to obtain an adjusted monitoring period.

[0108] Specifically, the terminal device adjusts the monitoring period based on a third parameter, The method further includes removing a monitoring time from the monitoring period, the time interval between which is smaller than a third parameter than a start time of the DRX ON period, and then obtaining an adjusted monitoring period.

[0109] That is, after obtaining a monitoring period based on any one of the above examples 1 to 8, an adjusted monitoring period can be obtained by taking a portion of the monitoring time from the monitoring period based on the third parameter.

[0110] specifically, If the monitoring period includes M durations, and each duration includes at least one monitoring time, or each duration includes at least one valid monitoring time, one or more monitoring times (or valid monitoring times) within a particular duration may be deleted after adjusting the monitoring period based on the third parameter. As shown in Figure 3-6, if the originally determined monitoring period includes monitoring times within the first and second durations, and after adjustment via the third parameter, the monitoring times in the gray portion within the second duration are deleted, leaving only the first monitoring time within the second duration, the adjusted monitoring period includes some of the monitoring times in the first duration and the remaining monitoring times after deleting the monitoring times in the gray portion within the second duration, as shown in the figure.

[0111] The monitoring period includes N monitoring time instants, and after adjusting the monitoring period based on the third parameter, one or more monitoring time instants (or valid monitoring time instants) may be deleted.

[0112] The monitoring period includes L monitoring slots, and after adjusting the monitoring period based on the third parameter, one or more monitoring times (or valid monitoring times) in a particular monitoring slot may be deleted.

[0113] The third parameter is used to indicate the minimum time required from the start of reception of the energy saving signal PDCCH by the terminal device until the terminal device can locate the start time of the DRX ON period (i.e., the time when normal data transmission begins within the DRX ON period). The third parameter may be described as PS_offsetMin, and may be preset, configured for the terminal device by a network device, or protocol-defined, but this is not an exhaustive list.

[0114] Regardless of whether the third parameter is configured by the network side for the terminal device or is protocol-defined, the network device can also adjust the monitoring period according to the third parameter to obtain an adjusted monitoring period. Furthermore, the network device can determine the monitoring period of the terminal device, and thereby transmit an energy-saving signal PDCCH to the terminal device at the corresponding monitoring position.

[0115] It can be seen from this that by adopting the above technical solution, a corresponding monitoring period can be determined according to at least one configuration parameter of the energy-saving signal search space, and then the energy-saving signal PDCCH can be monitored in the monitoring period. In this way, a technical solution for determining a monitoring period of an energy-saving signal by adopting configuration parameters is provided, filling a gap in the related art; furthermore, the implementation of the above technical solution does not require adding other parameters that need to be configured based on existing parameters, ensuring that the signaling overhead between the terminal device and the network device is not increased.

[0116] An embodiment of the present invention provides a terminal device, and as shown in FIG. 4-1, the communication terminal device comprises: The first communication unit 41 is configured to monitor an energy-saving signal PDCCH in a monitoring period before a discontinuous reception (DRX) ON period and after a monitoring start time, Wherein the monitoring period is determined by at least one configuration parameter of each of the K energy-saving signal search spaces, where K is an integer greater than or equal to 1.

[0117] The terminal device further comprises a first processing unit 42, which determines the monitoring start time based on a configured Power Saving (PS)-Offset and a start time of the DRX ON period.

[0118] As shown in FIG. 4-2, the network device: The second communication unit 51 transmits an energy saving signal PDCCH during a monitoring period before a discontinuous reception (DRX) ON period and after a monitoring start time, Wherein the monitoring period is determined by at least one configuration parameter of each of the K energy-saving signal search spaces, where K is an integer greater than or equal to 1.

[0119] The network device further comprises a second processing unit 52 for determining the monitoring start time based on a configured Power Saving (PS)-Offset and a start time of the DRX ON period.

[0120] This embodiment can be applied to a scenario in which one energy-saving signal search space is configured in a terminal device, and can also be applied to a scenario in which multiple energy-saving signal search spaces are configured in a terminal device. The technical solution according to this embodiment will be described with reference to several examples.

[0121] In Example 1, K=1, that is, one energy-saving signal search space is configured in the terminal device.

[0122] In this example, the monitoring period includes M durations of each of the K energy-saving signal search spaces, where M is an integer greater than or equal to one.

[0123] This example is for a scenario where K=1, so the monitoring period in this example includes M durations for the constructed energy-saving signal search space.

[0124] The above M may be configured or predefined, where if M is configured, the terminal device may receive M configured for the terminal device by a network device, specifically, may convey the M value via Radio Resource Control (RRC) signaling. Preferably, M=1.

[0125] Each duration of the M durations includes at least one monitoring time instant.

[0126] The terminal device may determine a corresponding monitoring period based on at least one configuration parameter of an energy-saving signal search space, where the at least one configuration parameter in the energy-saving signal search space, i.e., PDCCH search space, is: a first parameter for indicating the number of slots to be continuously monitored within a period of the corresponding energy-saving signal search space; The at least one second parameter may include at least one for indicating a starting symbol of a monitoring time of the energy saving signal PDCCH in the corresponding energy saving signal search space.

[0127] Here, the first parameter may be a "Duration" parameter in the PDCCH Search Space, and the second parameter may be a "monitoringSymbolsWithinSlot" parameter in the PDCCH Search Space.

[0128] In this example, the at least one monitoring time may be all the monitoring time in one duration, or may be a portion of the monitoring time in one duration.

[0129] In a preferred example, in the at least one monitoring time, each monitoring time must be a valid monitoring time.

[0130] In Example 2, the difference from Example 1 is that it explains the case where K>1, that is, it is a technical proposal for configuring multiple energy-saving signal search spaces in the terminal to monitor PDCCH-based energy-saving signals (i.e., energy-saving signals PDCCH).

[0131] The technical solution of this example is that the terminal device determines M durations within the monitoring period corresponding to each energy-saving signal search space among the K energy-saving signal search spaces (specifically, PDCCH search spaces) based on at least one configuration parameter corresponding to each energy-saving signal search space.

[0132] As in Example 1, the above M may be configured or predefined. Here, if M is configured, the terminal device may receive M configured for the terminal device by a network device, specifically, the M value may be conveyed via Radio Resource Control (RRC) signaling. Preferably, M=1.

[0133] The difference from Example 1 is that when K is greater than 1, there are multiple energy-saving signal search spaces, that is, the final monitoring period contains K*M durations.

[0134] In Example 3, the case where K>1 is also described, that is, a technical solution in which multiple energy-saving signal search spaces are configured in a terminal to monitor a PDCCH-based energy-saving signal (i.e., energy-saving signal PDCCH).

[0135] The difference from Example 2 is that in this example, the monitoring period includes M durations, where M is an integer greater than or equal to 1. That is, all K energy-saving signal search spaces correspond to the same M durations, for example, when M=1, all K energy-saving signal search spaces adopt the same one duration.

[0136] wherein the length of each of the M durations is: the length of the longest duration of at least one of the durations of the K energy-saving signal search spaces; Preset time length, a preset multiple of the longest duration of at least one of the durations of the K energy-saving signal search spaces; It can be one of a preset multiple of a preset length of time.

[0137] In Example 4, K=1, ie, an energy-efficient signal search space is constructed.

[0138] Different from all the above examples 1 to 3, in this example, the monitoring period includes N monitoring times in each of the K energy-saving signal search spaces, where N is an integer greater than or equal to 1.

[0139] In this example, K=1, so the monitoring period in this example includes N monitoring times of one configured energy-saving signal search space.

[0140] In Example 5, the difference from Example 4 is that it explains the case where K>1, that is, it is a technical proposal when multiple energy-saving signal search spaces are configured in the terminal and PDCCH-based energy-saving signals (i.e., energy-saving signals PDCCH) are monitored.

[0141] The technical solution of this example is that the terminal device determines N monitoring times within a monitoring period corresponding to each energy-saving signal search space among the K energy-saving signal search spaces (specifically, PDCCH search spaces) based on at least one configuration parameter corresponding to each energy-saving signal search space.

[0142] In Example 6, the case where K>1 is also described, that is, a technical solution in which multiple energy-saving signal search spaces are configured in a terminal to monitor a PDCCH-based energy-saving signal (i.e., energy-saving signal PDCCH).

[0143] The difference from Example 5 is that in this example, the monitoring period includes N monitoring times. That is, regardless of how many energy-saving signal search spaces there are, all of them use the same N monitoring times for monitoring. Here, the method of determining the N monitoring times may be to randomly select N monitoring times (or N valid monitoring times) within a monitoring period in any one energy-saving signal search space, or to select a portion (one or more) within each monitoring period in two or more energy-saving signal search spaces and finally combine the N monitoring times. Of course, other methods may exist, but an exhaustive list will not be provided here.

[0144] In Example 7, Unlike all the above examples, in this example, the monitoring period includes L monitoring slots in each of the K energy-saving signal search spaces, where L is an integer greater than or equal to 1.

[0145] The monitoring period in this example includes L monitoring slots of one energy-saving signal search space that is configured. Alternatively, when K is greater than 1, L monitoring slots are similarly determined for each energy-saving signal search space, and finally, the monitoring period includes K*L monitoring slots.

[0146] The above L may be configured or predefined, where if L is configured, the terminal equipment may receive L configured for the terminal equipment by the network equipment, and in particular may convey the L value via Radio Resource Control (RRC) signaling.

[0147] In a preferred example, the monitoring times included in the above L monitoring slots must be valid monitoring times. Here, the definition of validity within a valid monitoring time is the same as in Example 1, and will not be repeated. Furthermore, if the monitoring time included in a specific monitoring slot is invalid, the monitoring slot may not be counted.

[0148] The difference between Example 8 and Example 7 is that the monitoring period includes L monitoring slots, i.e., no matter how many energy-saving signal search spaces there are, they all adopt the same L monitoring slots for monitoring.

[0149] In Example 9, Based on the above examples, this example further includes adding a third parameter, and the terminal device adjusting the monitoring period based on the third parameter to obtain an adjusted monitoring period.

[0150] Specifically, the terminal device adjusts the monitoring period based on a third parameter, The method further includes removing a monitoring time from the monitoring period, the time interval between which is smaller than a third parameter than a start time of the DRX ON period, and then obtaining an adjusted monitoring period.

[0151] That is, after obtaining a monitoring period based on any one of the above examples 1 to 8, an adjusted monitoring period can be obtained by taking a portion of the monitoring time from the monitoring period based on the third parameter.

[0152] The third parameter is used to indicate the minimum time required from the start of reception of the energy saving signal PDCCH by the terminal device until the terminal device can align to the start time of the DRX ON period. The third parameter may be described as PS_offsetMin, and may be preset, configured for the terminal device by a network device, or protocol-defined, but this is not an exhaustive list.

[0153] Regardless of whether the above-mentioned third parameter is configured for the terminal device by the network side or is protocol-defined, the second processing unit 52 of the network device can also adjust the monitoring period according to the third parameter to obtain an adjusted monitoring period. Furthermore, the network device can determine the monitoring period of the terminal device, and thereby send an energy-saving signal PDCCH to the terminal device at the corresponding monitoring position via the second communication unit 51.

[0154] It can be seen from this that by adopting the above technical solution, a corresponding monitoring period can be determined according to at least one configuration parameter of the energy-saving signal search space, and then the energy-saving signal PDCCH can be monitored in the monitoring period. In this way, a technical solution for determining a monitoring period of an energy-saving signal by adopting configuration parameters is provided, filling a gap in the related art; furthermore, the implementation of the above technical solution does not require adding other parameters that need to be configured based on existing parameters, ensuring that the signaling overhead between the terminal device and the network device is not increased.
