Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and particularly to a method for sending a wake-up signal (WUS), a detection method, related devices, and a storage medium. Background Art

[0002] Machine Type Communications (MTC), also known as Machine-to-Machine (M2M), is the main application form of the Internet of Things (IoT) at the present stage. Currently, the MTC devices deployed in the market are mainly based on the Global System of Mobile communication (GSM) system. In recent years, due to the high spectral efficiency of LTE / LTE-A, more and more mobile operators have chosen LTE / LTE-A as the evolution direction of future broadband wireless communication systems. The MTC multi-type data services based on LTE / LTE-A will also be more attractive.

[0003] In the 3rd Generation Partnership Project (3GPP) Technical Report TR45.820 V200, several technologies applicable to Cellular-Internet of Things (C-IoT) are disclosed. Among them, the NarrowBand-Internet of Things (NB-IoT) technology is the most remarkable. The NB-IoT system focuses on radio frequency access technologies with low complexity and low throughput. The main research objectives include: improved indoor coverage, support for a large number of low-throughput user equipment, low delay sensitivity, ultra-low device cost, low device power consumption, and network architecture.

[0004] The network can send paging to terminals (User Equipment, UE) in the idle state and the connected state. The paging process can be triggered by the core network to notify a certain UE to receive a paging request, or can be triggered by the eNB to notify the update of system information. The paging message is scheduled by the Physical Downlink Control Channel (PDCCH) scrambled with the P-Radio Network Temporary Identifier (RNTI) and transmitted on the Physical Downlink Shared Channel (PDSCH). The terminal detects the corresponding PDCCH at the Paging Occasion (PO) to determine whether the PDSCH indicated by the PDCCH carries the paging message. If the terminal does not detect the corresponding PDCCH at this PO, it means there is no paging message at this PO. At this time, the terminal enters the sleep state, does not receive data, and waits until the next PO to detect again. This is called Discontinuous Reception (DRX). That is, the terminal needs to perform blind detection of the PDCCH at each PO, so the power consumption of the terminal is relatively large.

[0005] To reduce the power consumption of the terminal, a Wake up signal (WUS) is introduced. The base station sends a signal indicating whether to perform PDCCH detection before each PO. The terminal first detects the WUS and determines whether to detect the corresponding PDCCH according to the detection result of the WUS. When the WUS is detected, the terminal detects the PDCCH corresponding to the WUS. Otherwise, the terminal does not detect the PDCCH. The introduction of the WUS signal reduces the number of times the terminal detects the PDCCH, thus saving the power consumption of the terminal.

[0006] However, the existing WUS is for all terminals in the PO. That is, if one terminal needs to be woken up, the base station will send the WUS, and then other terminals belonging to the same PO will be woken up. These terminals will all detect the PDCCH, which increases the unnecessary number of times the terminal detects the PDCCH and limits the power consumption reduction effect of the terminal. Summary of the Invention

[0025] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be completely conveyed to those skilled in the art.

[0026] In the embodiments of the present invention, by sending grouped WUS or ungrouped WUS, the problem in the prior art that the sent WUS wakes up all terminals on the PO, increasing the unnecessary number of times for the terminals to detect the PDCCH, and thus the effect of reducing the terminal power consumption is not obvious is solved. At the same time, the embodiments of the present invention also reduce the problem of excessive resource overhead caused by grouped WUS in special scenarios. The method of the present invention will be explained and described in detail through several specific examples below:

[0027] The first embodiment of the present invention provides a method for sending a wake-up signal WUS. Refer to Figure 1 , the method includes:

[0028] S101. Send WUS through at least one of the first sending method, the second sending method, the third sending method, and the fourth sending method: The first sending method: send the first WUS on the first basic unit and the second WUS on the second basic unit; the second sending method: determine whether to send the third WUS or the fourth WUS within the basic unit through a preset condition; the third sending method: determine whether to send the fourth WUS or one of the third WUS and the fourth WUS within the basic unit through a first signaling; the fourth sending method: determine the fifth WUS to be sent through a second signaling and a basic unit index.

[0029] Specifically, in order to avoid the problem in the prior art of waking up all terminals under the same PO when only some terminals need to be woken up, in the embodiments of the present invention, the terminals under the same PO are grouped, and each group of terminals corresponds to a WUS, which is called grouped WUS. By sending the grouped WUS, the unnecessary number of times for the terminals to detect the PDCCH is reduced. This grouping can be preset, or it can also be configured through signaling according to the terminals to be woken up currently. Of course, if grouped WUS is always sent, for scenarios where all terminals need to be woken up, such as when sending system change information, sending ungrouped WUS will bring additional resource overhead.

[0030] It should be noted that the non-grouped WUS described in the embodiments of the present invention refers to the WUS corresponding to all terminals on the same PO; the grouped WUS refers to all terminals on the same PO grouped, and the WUS corresponding to each group of terminals.

[0031] In the embodiments of the present invention, the first sending method: send the first WUS on the first basic unit, and send the second WUS on the second basic unit;

[0032] Among them, the first WUS described in the embodiments of the present invention is a non-grouped WUS, and the second WUS is a grouped WUS. And in the first sending method described in the embodiments of the present invention, the first basic unit and / or the second basic unit are basic units determined by signaling indication and / or presetting.

[0033] That is to say, the first sending method described in the embodiments of the present invention enables the base station to perform switched transmission of different WUSs by sending different WUSs on different basic units.

[0034] It should be noted that the non-grouped WUS described in the embodiments of the present invention refers to the WUS corresponding to all UEs on the same PO; the grouped WUS refers to all UEs on the same PO grouped, and the WUS corresponding to each group of UEs.

[0035] The second sending method: determine the third WUS or the fourth WUS sent within the basic unit through preset conditions;

[0036] In the embodiments of the present invention, in the second sending method, the preset conditions include one or more of the following: the type of the terminal, the length of the search space of the downlink control channel PDCCH, the length of the WUS search space, the WUS sending length, and the number of groups.

[0037] When the preset condition is the type of the terminal, determining whether to send the third WUS or the fourth WUS within the basic unit through the preset condition includes: when there are W terminals of the coverage enhancement type among the terminals corresponding to the basic unit, or when there are Z terminals in the coverage enhancement mode among the terminals corresponding to the basic unit, or when the type of the terminals corresponding to the basic unit exceeds the preset number, determining that the third WUS is sent within the basic unit, otherwise the fourth WUS is sent, where both W and Z are positive integers greater than 1;

[0038] When the preset condition is the length of the PDCCH search space, determining whether to send the third WUS or the fourth WUS within the basic unit through the preset condition includes: when the length of the PDCCH search space is greater than or equal to the first threshold, determining that the third WUS is sent by the basic unit, otherwise the fourth WUS is sent;

[0039] When the preset condition is the length of the WUS search space, determining whether to send the third WUS or the fourth WUS within the basic unit according to the preset condition includes: when the length of the WUS search space is greater than or equal to the second threshold, determining that the basic unit sends the third WUS; otherwise, sending the fourth WUS.

[0040] When the preset condition is the WUS transmission length, determining whether to send the third WUS or the fourth WUS within the basic unit according to the preset condition includes: when the WUS transmission length is greater than or equal to the third threshold, determining that the basic unit sends the third WUS; otherwise, sending the fourth WUS.

[0041] When the preset condition is the number of groups, determining whether to send the third WUS or the fourth WUS within the basic unit according to the preset condition includes: when the number of groups is the first number of groups, determining that the basic unit sends the third WUS; when the number of groups is the second number of groups, determining that the basic unit sends the fourth WUS.

[0042] It should be noted that only one of the preset conditions in the second transmission mode of the embodiment of the present invention can be set, or multiple conditions can be combined and set. Specifically in implementation, those skilled in the art can set according to actual needs, and the embodiment of the present invention does not make specific limitations in this regard.

[0043] Specifically in implementation, the third WUS in the embodiment of the present invention is an ungrouped WUS, and the fourth WUS is a grouped WUS, or both the third WUS and the fourth WUS are grouped WUSs.

[0044] When the third WUS is an ungrouped WUS and the fourth WUS is a grouped WUS, the time domain length of the third WUS is greater than the time domain length of the fourth WUS.

[0045] When the third WUS and the fourth WUS are grouped WUSs, the sequence corresponding to the third WUS is the first sequence, and the sequence corresponding to the fourth WUS is the second sequence, where the first sequence is the sequence corresponding to the first number of groups, and the second sequence is the sequence corresponding to the second number of groups.

[0046] In the third transmission mode of the embodiment of the present invention, the first signaling includes: a first enabling signaling.

[0047] Simply put, it means that when the grouped WUS is enabled, the base station can also send an ungrouped WUS.

[0048] In the embodiment of the present invention, in the fourth sending method, the second signaling includes at least one of the following: the maximum number of groups corresponding to the fifth WUS, the minimum number of groups corresponding to the fifth WUS, the number of groups corresponding to the fifth WUS, and the indication of the change in the number of groups corresponding to the fifth WUS.

[0049] That is to say, the fourth sending method described in the embodiment of the present invention is all grouped WUS.

[0050] For example, assuming that the basic unit of the embodiment of the present invention is a DRX cycle, the number of groups corresponding to the grouped WUS is configured to be 2 by higher-layer signaling (the preset maximum number of groups is 8), then all the fifth WUSs sent by the base station in the first DRX cycle within the signaling enabling period are grouped WUSs with a group number of 2, the fifth WUSs sent in the second DRX cycle are grouped WUSs with a group number of 4, the fifth WUSs sent in the third DRX cycle are grouped WUSs with a group number of 8, the fifth WUSs sent in the fourth DRX cycle are grouped WUSs with a group number of 2, and so on.

[0051] It should be noted that the basic unit described in the embodiment of the present invention is M POs, N discontinuous reception DRX cycles, P enhanced discontinuous reception eDRX cycles, or K radio frames, where M, N, P, and K are positive integers greater than 0 respectively;

[0052] The second embodiment of the present invention provides a WUS sending method, which only illustrates the method for the base station to send WUS in the embodiment of the present invention in several specific implementation manners:

[0053] The following is an explanation of the first sending method for the embodiment of the present invention: Specific implementation manner 1

[0055] Assume that the basic unit is a DRX cycle, the first basic unit is the d-th in every D DRX cycles, the second basic unit is the DRX cycles other than the first basic unit. Assume that the terminal index of the terminal corresponding to the T-th PO in the first basic unit is y T1 , y T2 , y T3 , y T4 , that is, the total number of terminals corresponding to this PO is 4. Assume that the terminal index of the terminal corresponding to the M-th PO in the second basic unit is y M1 , y M2 , y M3， Assume that the number of groups corresponding to the grouped WUS is fixed at 2, then the terminal indexes of the terminals corresponding to the grouped WUS1 are y M1 , y M2 ; the terminal indexes of the terminals corresponding to the grouped WUS2 are y M3; When sending, the sequences corresponding to packet WUS1 and packet WUS2 are different, where the base station determines the DRX cycle index according to the DRX cycle period and the radio frame index.

[0056] All WUSs sent by the base station within the first basic unit are ungrouped WUSs. Taking the T-th PO as an example, if the terminal index is y T1 , y T2 , y T3 and y T4 among the terminals needs to be woken up, the base station sends an ungrouped WUS;

[0057] All WUSs sent within the second basic unit are grouped WUSs, where the number of groups of the grouped WUSs is 2. Taking the M-th PO within the (d - 1)-th DRX cycle as an example, if the terminal index is y M1 , y M2 among the terminals needs to be woken up, then the base station sends packet WUS1. If the terminal index is y M3 among the terminals needs to be woken up, then the base station sends packet WUS2. If only the terminal index is y M3 needs to be woken up, then the base station only sends packet WUS2. Specific Embodiment 2

[0059] Assume that the basic unit is a DRX cycle. Assume that the first basic unit is configured by a signaling, where the signaling is: with an interval of k. Then the first basic unit is the DRX cycle for which the DRX cycle index modulo k is equal to F, and the second basic unit is the DRX cycles other than the first basic unit, where F is a pre-set value. Preferably, when the value of F is 0, assume that the terminal index of the terminal corresponding to the T-th PO within the first basic unit is y T1 , y T2 , y T3 , y T4 , that is, the total number of terminals corresponding to this PO is 4. Assume that the terminal index of the terminal corresponding to the M-th PO within the second basic unit is y M1 , y M2 . Assume that the number of groups corresponding to the grouped WUS is fixed at 2. Then the terminal index of the terminal corresponding to packet WUS1 is y M1 , and the terminal index of the terminal corresponding to packet WUS2 is y M2 . When sending, the sequences corresponding to packet WUS1 and packet WUS2 are different, where the base station determines the DRX cycle index according to the DRX cycle period and the radio frame index.

[0060] All WUSs sent by the base station within the first basic unit are ungrouped WUSs. Taking the T-th PO as an example, if the terminal index is y T1 , y T2 , y T3 , yT4 If any one of the terminals in the terminal needs to be woken up, the base station sends an ungrouped WUS;

[0061] All WUSs sent by the base station within the second basic unit are grouped WUSs, where the number of groups of the grouped WUSs is 2. Taking the Mth PO as an example, if the terminal index yM1 needs to be woken up, then the base station sends the grouped WUS1. If the terminal index y M2 needs to be woken up, then the base station sends the grouped WUS2. If only the terminal index y M2 needs to be woken up, then the base station only sends the grouped WUS2. Specific Embodiment Three

[0063] Assume that the basic unit is a DRX cycle, and the first basic unit / second basic unit is obtained through signaling, where the signaling is: the first basic unit enabling indication. Assume that the first WUS enabling indication is H bits, and each bit corresponds to 1 DRX cycle. When it is 1, it represents the first basic unit. When it is 0, it represents the second basic unit, or when it is 0, it represents the first basic unit, and when it is 1, it represents the second basic unit; Assume that the terminal index of the terminal corresponding to the Tth PO within the first basic unit is y T1 , y T2 , y T3 , y T4 , that is, the total number of terminals corresponding to this PO is 4. Assume that the terminal index of the terminal corresponding to the Mth PO within the second basic unit is y M1 , y M2 , y M3 , y M4 , assuming that the number of groups corresponding to the grouped WUS is fixed at 2, then the terminal indices of the terminals corresponding to the grouped WUS1 are y M1 , y M2 , and the terminal indices of the terminals corresponding to the grouped WUS2 are y M3 , y M4 , and the sequences corresponding to the grouped WUS1 and the grouped WUS2 are different when sending.

[0064] All WUSs sent by the base station within the first basic unit are ungrouped WUSs. Taking the Tth PO as an example, if the terminal index y T1 , y T2 , y T3 , y T4 of any one of the terminals needs to be woken up, the base station sends an ungrouped WUS. All WUSs sent within the second basic unit are second WUSs, where the number of groups corresponding to the sent second WUSs is 2. Taking the Mth PO as an example, if the terminal index y M1 , y M2 of any one of the terminals needs to be woken up, the base station sends the grouped WUS1, and the terminal index is yM3 , y M4 When any one of the terminals in the terminal needs to be woken up, the base station sends a packet WUS2.

[0065] The above grouping of all terminals on the PO is only an example, and other grouping methods are not excluded.

[0066] The following are examples of several specific implementation manners for the second sending manner of the embodiments of the present invention: Specific implementation manner 1

[0068] Assume that the basic unit is a PO and the length of the PDCCH search space corresponding to the T-th PO is 1024. Assume that the preset threshold 1 (i.e., the first threshold described in the embodiments of the present invention) is 1024. Assume that the signaling-configured WUS-Alpha = 1 / 4. Then the length of the search space corresponding to WUS is 1024*(1 / 4) = 256.

[0069] Since the PDCCH search space length 1024 is greater than or equal to the threshold 1, the base station sends a third WUS, where the third WUS is an ungrouped WUS and the time domain length of the third WUS is the same as the length of the WUS search space, that is, 256. Specific implementation manner 2

[0071] Assume that the basic unit is a PO and the length of the PDCCH search space corresponding to the T-th PO is 512. Assume that the threshold 1 is 1024. Assume that the configured WUS-Alpha = 1 / 4. Then the length of the search space corresponding to WUS is 512*(1 / 4) = 128;

[0072] Since the length of the PDCCH search space 512 is less than or equal to the threshold 1, the base station sends a fourth WUS, and the fourth WUS is a grouped WUS and the time domain length is less than or equal to that of the WUS search space. Specific implementation manner 3

[0074] Assume that the basic unit is a PO and the length of the PDCCH search space corresponding to the T-th PO is 1024. Assume that the signaling-configured WUS-Alpha = 1 / 4. Then the length of the search space corresponding to WUS is 1024*(1 / 4) = 256. Assume that the preset threshold 2 is 128;

[0075] Since the WUS search space length 256 is greater than or equal to the threshold 2 (i.e., the second threshold described in the embodiments of the present invention), the base station sends a third WUS, where the third WUS is an ungrouped WUS and the time domain length is the same as the length of the WUS search space, that is, 256. Specific implementation manner 4

[0077] Assume that the basic unit is PO and the length of the PDCCH search space corresponding to the T-th PO is 512. Assume that the configured WUS-Alpha = 1 / 4. Then the length of the search space corresponding to WUS is 512*(1 / 4) = 128. Assume that the threshold 2 is 256;

[0078] Since the length of the WUS search space 128 is less than the threshold 2, the base station sends the fourth WUS. The fourth WUS is a grouped WUS and the time domain length is less than or equal to that of the WUS search space. Specific Embodiment Five

[0080] Assume that the basic unit is PO and the terminal indices corresponding to the T-th PO are y1, y2, y3, and y4, where the terminal with the terminal index y4 is in the coverage enhancement mode;

[0081] The base station sends the third WUS. The third WUS is an ungrouped WUS and the time domain length is the same as that of the WUS search space. Specific Embodiment Six

[0083] Assume that the basic unit is PO and the terminal indices corresponding to the T-th PO are y1, y2, y3, and y4, where the terminal with the terminal index y4 is a coverage enhancement terminal;

[0084] The base station sends the third WUS. The third WUS is an ungrouped WUS and the time domain length is the same as that of the WUS search space. Specific Embodiment Seven

[0086] Assume that the basic unit is PO and the terminal indices corresponding to the T-th PO are y1, y2, y3, and y4, where none of the terminals is a coverage enhancement terminal or in the coverage enhancement mode;

[0087] The base station sends the fourth WUS. The fourth WUS is a grouped WUS and the time domain length is less than or equal to that of the WUS search space. Specific Embodiment Eight

[0089] Assume that the basic unit is PO, the length of the PDCCH search space corresponding to the T-th PO is 1024, and the length of the PDCCH search space corresponding to the (T + 1)-th PO is 512. Assume that the preset threshold 1 is 1024.

[0090] For the T-th PO, since the length of the PDCCH search space 1024 is greater than or equal to the threshold 1, the base station sends the third WUS, where the time domain length of the third WUS is A1. For the (T + 1)-th PO, since the length of the PDCCH search space 512 is less than the threshold 1, the base station sends the fourth WUS, where the time domain length of the fourth WUS is A2, and A1 > A2. Specific Embodiment Nine

[0092] Assume that the basic unit is a PO, the length of the PDCCH search space corresponding to the T-th PO is 1024, the length of the PDCCH search space corresponding to the (T + 1)-th PO is 512. Assume that the signaling-configured WUS-Alpha = 1 / 4, and the preset threshold 2 is 128;

[0093] For the T-th PO, since the WUS search space length 1024 / 4 is greater than or equal to the threshold 2, the base station sends the third WUS, where the time domain length of the third WUS is A3. For the (T + 1)-th PO, since the WUS search space length 512 / 4 is less than the threshold 2, the base station sends the fourth WUS, where the time domain length of the fourth WUS is A4, and A3 > A4. Specific Embodiment Ten

[0095] Assume that the basic unit is a PO, and there are 4 terminals corresponding to the T-th PO. Among them, the terminal types of terminal A and terminal B are terminals of R15 version, and the terminal types of terminal C and terminal D are terminals of R16 version. Therefore, since there are multiple terminal types, the base station sends the third WUS, where the third WUS is not grouped WUS; that is, if any one of terminal A, terminal B, terminal C, and terminal D needs to be woken up, the base station sends the third WUS. Specific Embodiment Eleven

[0097] Assume that the basic unit is a PO, and the base station sends the third WUS or the fourth WUS according to the number of groups to be grouped. Among them, when the number of groups is the first number of groups, the third WUS is sent, where the third WUS is grouped WUS and the corresponding sequence is the sequence when the number of groups is the first number of groups. When the number of groups is the second number of groups, the fourth WUS is sent, where the fourth WUS is grouped WUS and the corresponding sequence is the sequence when the number of groups is the second number of groups.

[0098] The following are several examples of specific embodiments of the third sending method according to the embodiments of the present invention:

[0099] Assume that the first enabling signaling is: grouped WUS enabling signaling. When the corresponding value is 1, it indicates enabling grouped WUS, otherwise it indicates disabling grouped WUS Specific Embodiment One

[0101] Assume that the value corresponding to the grouped WUS enabling signaling is 1, then the base station sends the fourth WUS, where the fourth WUS is grouped WUS; Specific Embodiment Two

[0103] Assume that the value corresponding to the grouped WUS enabling signaling is 1, then the base station sends the third WUS or the fourth WUS; among them, the third WUS is not grouped WUS, and the fourth WUS is grouped WUS.

[0139] That is to say, all the WUSs received by the fourth detection method in the embodiments of the present invention are grouped WUSs.

[0140] It should be noted that the basic unit in the embodiments of the present invention is M POs, N discontinuous reception DRX cycles, P enhanced discontinuous reception eDRX cycles, or K radio frames, where M, N, P, and K are positive integers greater than 0 respectively.

[0141] The fourth embodiment of the present invention provides a WUS detection method, which details the method for detecting WUS in the embodiments of the present invention through only a few specific implementation manners:

[0142] The following are several specific implementation manners for the first detection method in the embodiments of the present invention: Specific implementation manner 1

[0144] Assume that the basic unit is a DRX cycle. The first basic unit is the d-th one in every D DRX cycles (the terminal can obtain the DRX cycle index based on the radio frame index and the DRX cycle period). The second basic unit is the basic unit other than the first basic unit. Assume that the terminal indices of the terminals corresponding to the T-th PO within the DRX cycle are y1, y2, y3, y4, that is, the total number of terminals corresponding to this PO is 4. Assume that the number of groups corresponding to the grouped WUS is fixed at 2; the terminal indices of the terminals corresponding to the grouped WUS1 are y1 and y2; the terminal indices of the terminals corresponding to the grouped WUS2 are y3 and y4; where the grouped WUS1 and the grouped WUS2 correspond to different time domain positions;

[0145] The terminal performs non-grouped WUS detection on the PO within the first basic unit;

[0146] Within the second basic unit of the terminal; taking T POs as an example, the terminals with terminal indices y1 and y2 perform grouped WUS1 detection at the time domain position corresponding to the grouped WUS1, and the terminals with terminal indices y3 and y4 perform grouped WUS2 detection at the time domain position corresponding to the grouped WUS2. The terminal determines the detection of the corresponding PDCCH according to the detection result of the WUS. Specific implementation manner 2

[0148] Assume that the basic unit is a DRX cycle, and the first basic unit is obtained through signaling, where the signaling is: an interval of k. Then, the first basic unit is a DRX cycle whose DRX cycle index modulo k is equal to F, and other DRX cycles are the second basic unit, where F is a pre-set value. Preferably, the value of F is 0. Assume that the terminal indices of the terminals corresponding to the T-th PO are y1, y2, y3, y4, that is, the total number of terminals corresponding to this PO is 4. Assume that the number of groups corresponding to the grouped WUS is fixed at 2; then the terminals with terminal indices y1 and y2 correspond to the grouped WUS1; the terminals with terminal indices y3 and y4 correspond to the grouped WUS2; where the grouped WUS1 and the grouped WUS2 correspond to different time domain positions.

[0149] The terminal performs detection without grouped WUS on the PO corresponding to the first basic unit.

[0150] The terminal performs detection according to grouped WUS on the PO corresponding to the second basic unit. Taking the T-th PO as an example, the terminals with terminal indices y1 and y2 perform detection according to the grouped WUS1, and the terminals with terminal indices y3 and y4 perform detection according to the grouped WUS2. The terminal determines the detection of the corresponding PDCCH according to the detection result of the WUS. Specific Embodiment Three

Assume that this indication is H bits, and each bit corresponds to 1 DRX cycle. When it is 1, it represents the first basic unit, and when it is 0, it represents the second basic unit; or when it is 1, it represents the second basic unit, and when it is 0, it represents the first basic unit.

[0153] The terminal can implicitly obtain the DRX cycle index according to the radio frame index and the DRX cycle period. The terminal performs detection without grouped WUS on the PO corresponding to the first basic unit, and the terminal performs detection according to the second WUS on the PO corresponding to the second basic unit.

Assume that the length of the PDCCH search space is 1024. Assume that the pre-set threshold 1 is 1024. Assume that the configured WUS-Alpha = 1 / 4. Then, the search space length corresponding to the WUS is 1024*(1 / 4) = 256;

[0157] Since the length of the PDCCH search space is greater than or equal to threshold 1, the terminal performs the third WUS detection, where the length of the WUS during detection is equal to 256, and the terminal determines the detection of the corresponding PDCCH according to the detection result of the WUS.

The number of configured groups is 2. Suppose the grouped WUS corresponding to terminal A is grouped WUS1.

[0162] Since the length of the WUS search space, 256, is greater than or equal to threshold 2, terminal A performs the third WUS detection, where the length of the WUS during detection is equal to 256. Terminal A performs the detection according to grouped WUS1. The terminal determines the detection of the PDCCH according to the detection result of the WUS. Specific Embodiment 4

Suppose the grouped WUS corresponding to terminal A is grouped WUS1.

[0165] Since the length of the WUS search space, 128, is less than threshold 2, the terminal performs the fourth WUS detection, where the fourth WUS is the grouped WUS. Terminal A performs the detection according to grouped WUS1. The terminal determines the detection of the PDCCH according to the detection result of the WUS. Specific Embodiment 5

When the terminal detects the fourth WUS corresponding to the PO, it performs detection according to the grouped WUS, where the time domain length corresponding to the third WUS is greater than that of the fourth WUS. If any one of the third and fourth WUSs is detected, then the terminal performs PDCCH detection. When neither the third WUS nor the fourth WUS is detected, the terminal does not perform PDCCH detection. The non-grouped WUS and the grouped WUS are located at different time domain positions or correspond to different sequences. Specific Embodiment Five

[0216] The terminal determines the DRX cycle index according to the radio frame index and the DRX cycle period, and the terminal determines the WUS change interval index according to the DRX cycle index; assume that the first WUS change interval is DRX cycle index 0 and cycle index 1, the second WUS change interval is DRX cycle index 2 and cycle index 3, and so on.

[0217] Then the terminal with terminal index y1 detects on the corresponding PO according to grouped WUS1 within 2 DRX cycles in the first WUS change interval (assume it is the i-th DRX cycle and the (i + 1)-th DRX cycle); within 2 DRX cycles in the second WUS change interval (assume it is the (i + 2)-th DRX cycle and the (i + 3)-th DRX cycle), it detects on the corresponding PO according to grouped WUS1, and the terminal determines the detection of PDCCH according to the detection result of WUS.

[0218] The terminal with terminal index y2 performs detection according to grouped WUS1 on the corresponding PO within 2 DRX cycles in the first WUS change interval; and performs detection according to grouped WUS1 on the corresponding PO within 2 DRX cycles in the second WUS change interval. The terminal determines the PDCCH detection based on the detection result of WUS.

[0219] The terminal with terminal index y3 performs detection according to grouped WUS1 on the corresponding PO within 2 DRX cycles in the first WUS change interval; and performs detection according to grouped WUS2 on the corresponding PO within 2 DRX cycles in the second WUS change interval. The terminal determines the PDCCH detection based on the detection result of WUS.

[0220] The terminal with terminal index y4 performs detection according to grouped WUS1 on the corresponding PO within 2 DRX cycles in the first WUS change interval; and performs detection according to grouped WUS2 on the corresponding PO within 2 DRX cycles in the second WUS change interval. The terminal determines the PDCCH detection based on the detection result of WUS.

[0221] The terminal with terminal index y5 performs detection according to grouped WUS2 on the corresponding PO within 2 DRX cycles in the first WUS change interval; and detects grouped WUS3 on the corresponding PO within 2 DRX cycles in the second WUS change interval. The terminal determines the PDCCH detection based on the detection result of WUS.

[0222] The terminal with terminal index y6 performs detection according to grouped WUS2 on the corresponding PO within 2 DRX cycles in the first WUS change interval; and performs detection according to grouped WUS3 on the corresponding PO within 2 DRX cycles in the second WUS change interval. The terminal determines the PDCCH detection based on the detection result of WUS.

[0223] The terminal with terminal index y7 performs detection according to grouped WUS2 on the corresponding PO within 2 DRX cycles in the first WUS change interval; and performs detection according to grouped WUS4 on the corresponding PO within 2 DRX cycles in the second WUS change interval. The terminal determines the PDCCH detection based on the detection result of WUS.

[0224] The terminal with terminal index y8 performs detection according to grouped WUS2 on the corresponding PO within 2 DRX cycles in the first WUS change interval; and performs detection according to grouped WUS4 on the corresponding PO within 2 DRX cycles in the second WUS change interval. The terminal determines the PDCCH detection based on the detection result of WUS, and so on.

[0225] In the above embodiments, it is taken that the terminals corresponding to the PO within the DRX cycle are the same as an example.

[0226] In the above embodiments, the method for the terminal to detect signals is a prior art. A common method is as follows: The terminal performs correlation detection on the received wake-up signal according to the generated wake-up signal. If an energy peak is detected, the terminal considers that the wake-up signal is detected; otherwise, the terminal considers that the wake-up signal is not detected. Other detection schemes are not excluded.

[0227] The fifth embodiment of the present invention provides a wake-up signal WUS sending device. Refer to Figure 3 , including:

[0228] A sending unit 31 sends WUS through at least one of the following sending methods:

[0229] The first sending method: Send the first WUS on the first basic unit and send the second WUS on the second basic unit;

[0230] The second sending method: Determine whether to send the third WUS or the fourth WUS in the basic unit according to a preset condition;

[0231] The third sending method: Determine whether to send the fourth WUS in the basic unit through a first signaling, or one of the third WUS and the fourth WUS;

[0232] The fourth sending method: Determine the fifth WUS to be sent through a second signaling and a basic unit index.

[0233] In the embodiments of the present invention, the sending unit 31 only sends WUS to the terminals that need to be woken up, thus effectively solving the problem in the prior art that the WUS sent wakes up all the terminals on the PO, causing the terminals that do not need to be woken up to also detect the PDCCH, resulting in limited power consumption reduction effect of the terminals.

[0234] Specifically, the sending unit 31 in the embodiments of the present invention sends WUS to all the terminals in the group corresponding to the pre-woken terminal or all the terminals on a PO according to the pre-woken terminal.

[0235] That is to say, in the embodiments of the present invention, by pre-grouping all the terminals on the same PO and sending WUS to the group where the pre-woken terminal is located, it is realized to only send WUS to the terminals that need to be woken up, thus effectively solving the problem in the prior art that the WUS sent wakes up all the terminals on the PO, causing the terminals that do not need to be woken up to also detect the PDCCH, resulting in limited power consumption reduction effect of the terminals.

[0236] Specifically, in order to avoid the problem in the prior art that when only some terminals need to be woken up, all terminals under the same PO need to be woken up. In the embodiments of the present invention, the terminals under the same PO are grouped. This grouping can be preset, or it can also be configured by signaling according to the terminals that need to be woken up currently. By sending WUS to the terminals within the group, it is avoided that the terminals that do not need to be woken up also detect the PDCCH, resulting in limited power consumption reduction effect of the terminals.

[0237] It should be noted that the ungrouped WUS described in the embodiments of the present invention refers to the WUS corresponding to all terminals on the same PO, and the grouped WUS refers to all terminals on the same PO grouped, and each group of terminals corresponds to the same WUS.

[0238] It should be noted that the number of groups described in the embodiments of the present invention can be set separately for each PO, or the same number of groups can be set for the POs within a certain time period or all POs.

[0239] In the embodiments of the present invention, the first sending method: send the first WUS on the first basic unit, and send the second WUS on the second basic unit;

[0240] Among them, the first WUS described in the embodiments of the present invention is an ungrouped WUS, and the second WUS is a grouped WUS. And in the first sending method described in the embodiments of the present invention, the first basic unit and / or the second basic unit are determined by signaling indication and / or presetting.

[0241] That is to say, the first sending method described in the embodiments of the present invention enables the base station to perform a switching transmission of different WUS by sending different WUS on different basic units.

[0242] It should be noted that the ungrouped WUS described in the embodiments of the present invention refers to: the WUS corresponding to all terminals on the same PO; the grouped WUS refers to: all terminals on the same PO are divided into groups, and the WUS corresponding to each group of terminals.

[0243] The second sending method: determine the third WUS or the fourth WUS sent within the basic unit through preset conditions;

[0244] In the embodiments of the present invention, in the second sending method, the preset conditions include one or more of the following: the type of the terminal, the length of the PDCCH search space, the length of the WUS search space, the WUS sending length, and the number of groups.

[0245] For the second sending method of the embodiments of the present invention, the sending unit 31 of the embodiments of the present invention specifically performs the following operations:

[0246] When the preset condition is the terminal type, the sending unit 31 is further configured to determine that the basic unit sends the third WUS when the types of W terminals in the terminals corresponding to the basic unit are coverage enhancement, or when Z terminals in the terminals corresponding to the basic unit are in the coverage enhancement mode, or when the type of the terminal corresponding to the basic unit exceeds the preset number; otherwise, the fourth WUS is sent, where both W and Z are positive integers greater than 1; when the preset condition is the length of the PDCCH search space, when the length of the PDCCH search space is greater than or equal to the first threshold, it is determined that the basic unit sends the third WUS, otherwise the fourth WUS is sent; when the preset condition is the length of the WUS search space, when the length of the WUS search space is greater than or equal to the second threshold, it is determined that the basic unit sends the third WUS, otherwise the fourth WUS is sent; when the preset condition is the WUS sending length, when the WUS sending length is greater than or equal to the third threshold, it is determined that the basic unit sends the third WUS, otherwise the fourth WUS is sent; when the preset condition is the number of groups, when the number of groups is the first number of groups, it is determined that the basic unit sends the third WUS, and when the number of groups is the second number of groups, the fourth WUS is sent through the basic unit.

[0247] It should be noted that only one of the preset conditions in the second sending method described in the embodiments of the present invention may be set, or multiple conditions may be combined and set. Specifically in implementation, those skilled in the art can set according to actual needs, and the embodiments of the present invention do not make specific limitations on this.

[0248] Specifically in implementation, the third WUS described in the embodiments of the present invention is an ungrouped WUS, and the fourth WUS is a grouped WUS, or both the third WUS and the fourth WUS are grouped WUSs.

[0249] When the third WUS is an ungrouped WUS and the fourth WUS is a grouped WUS, the time domain length of the third WUS is greater than the time domain length of the fourth WUS.

[0250] When the third WUS and the fourth WUS are grouped WUSs, the sequence corresponding to the third WUS is the first sequence, and the sequence corresponding to the fourth WUS is the second sequence, where the first sequence is the sequence corresponding to the first number of groups, and the second sequence is the sequence corresponding to the second number of groups.

[0251] That is, in the embodiments of the present invention, when the signal is poor, or when the configuration of the terminal is relatively low and in the coverage enhancement mode, the third WUS is sent through the basic unit in the second sending method so that the terminal can receive the WUS.

[0252] In the third sending method according to the embodiments of the present invention, the first signaling includes: a first enabling signaling.

[0253] Simply put, when the base station enables packet WUS, it can also send non-packet WUS.

[0254] In the embodiments of the present invention, in the fourth sending method, the second signaling includes at least one of the following: the maximum number of groups corresponding to the fifth WUS, the minimum number of groups corresponding to the fifth WUS, the number of groups corresponding to the fifth WUS, and an indication of the change in the number of groups corresponding to the fifth WUS.

[0255] That is to say, the fourth sending method described in the embodiments of the present invention is all packet WUS.

[0256] Specifically, in the embodiments of the present invention, within the signaling enabling period, based on the maximum number of groups corresponding to the WUS or the minimum number of groups corresponding to the WUS, and according to the group number change interval corresponding to the WUS, the corresponding packet WUS in the fifth WUS is sent through a basic unit determined by a preset signaling.

[0257] For example, assuming that the basic unit in the embodiments of the present invention is a DRX cycle, and the number of groups corresponding to the packet WUS is configured as 2 through a high-layer signaling (the preset maximum number of groups is 8), then all the fifth WUS sent by the base station in the first DRX cycle within the signaling enabling period are packet WUS with a group number of 2, the fifth WUS sent in the second DRX cycle are packet WUS with a group number of 4, the fifth WUS sent in the third DRX cycle are packet WUS with a group number of 8, the fifth WUS sent in the fourth DRX cycle are packet WUS with a group number of 2, and so on.

[0258] It should be noted that the basic unit described in the embodiments of the present invention is M POs, N non-consecutive receiving DRX cycles, P enhanced non-consecutive receiving eDRX cycles, or K radio frames, where M, N, P, and K are positive integers greater than 0 respectively;

[0259] Generally speaking, the base station in the embodiments of the present invention follows a pre-agreed packet transformation rule with the terminal and only sends WUS to the terminal corresponding to the PDCCH. Therefore, the terminal in the embodiments of the present invention can effectively avoid unnecessary steps of detecting the PDCCH, thus saving the power consumption of the terminal.

[0260] For the relevant content of the embodiments of the present invention, reference can be made to the relevant parts of the first embodiment of the present invention for understanding, and the present invention will not elaborate on this in detail.

[0261] The sixth embodiment of the present invention provides a wake-up signal WUS detection device, see Figure 4 , and the device includes:

[0262] A receiving unit 41, configured to receive a wake-up signal;

[0263] A detecting unit 42, configured to detect the wake-up signal through at least one of the following detecting manners, and receive the wake-up signal WUS; detect the wake-up signal through at least one of the following detecting manners

[0264] The first detecting manner: perform detection according to a first WUS in a first basic unit and perform detection according to a second WUS in a second basic unit;

[0265] The second detecting manner: determine, according to a preset condition, whether to perform detection according to a third WUS, or according to a fourth WUS, or perform detection according to the third WUS and the fourth WUS in the basic unit;

[0266] The third detecting manner: determine, according to a first signaling, whether to perform detection according to the fourth WUS, or perform detection according to the third WUS and the fourth WUS in the basic unit;

[0267] The fourth detecting manner: determine, according to a second signaling, to perform detection according to a fifth WUS in the basic unit.

[0268] The terminal according to the embodiment of the present invention receives a WUS through a packet rule predetermined with a base station, and parses the received wake-up signal, so as to determine whether to receive a PDCCH / PDSCH, so that the terminal can effectively avoid unnecessary steps of detecting a PDCCH, thereby significantly saving the power consumption of the terminal.

[0269] It should be noted that, in the embodiment of the present invention, the first WUS is an ungrouped WUS, the second WUS is a grouped WUS, the third WUS is an ungrouped WUS, the fourth WUS is a grouped WUS, or both the third WUS and the fourth WUS are grouped WUSs, and the fifth WUS is a grouped WUS.

[0270] Wherein, the ungrouped WUS in the embodiment of the present invention refers to: the WUS corresponding to the PO where the terminal is located, and the grouped WUS refers to: the WUS corresponding to the group where the terminal is located.

[0271] In order to avoid the problem in the prior art that when only some terminals need to be woken up, all terminals under the same PO need to be woken up, the embodiment of the present invention groups the terminals under the same PO. This grouping can be preset, or can also be configured through signaling according to the terminals that need to be woken up currently. By sending a WUS to the terminals in the group, it is avoided that the terminals that do not need to be woken up also need to detect a PDCCH, so that the power consumption reduction effect of the terminal is limited.

[0272] In an embodiment of the present invention, when the third WUS is an ungrouped WUS and the fourth WUS is a grouped WUS, the time domain length of the third WUS is greater than the time domain length of the fourth WUS;

[0273] When the third WUS and the fourth WUS are grouped WUSs, the sequence corresponding to the third WUS is the first sequence, and the sequence corresponding to the fourth WUS is the second sequence, where the first sequence is the sequence corresponding to the first number of groups, and the second sequence is the sequence corresponding to the second number of groups.

[0274] In the first detection method, the first basic unit and / or the second basic unit are basic units determined by signaling indication and / or presetting.

[0275] For example, in specific implementation, the terminal in the embodiment of the present invention can obtain the DRX cycle index according to the radio frame index and the DRX cycle period, and determine the preset basic unit in the first detection method according to the DRX cycle index.

[0276] The preset conditions in the second detection method in the embodiment of the present invention include one or more of the following: the length of the PDCCH search space and the length of the WUS search space.

[0277] When the preset condition is the length of the PDCCH search space, the detection unit 42 is further configured to determine to perform detection according to the third WUS when the length of the PDCCH search space is greater than or equal to the first threshold, otherwise perform detection according to the fourth WUS;

[0278] When the preset condition is the length of the WUS search space, the detection unit 42 is further configured to determine to perform detection according to the third WUS when the length of the WUS search space is greater than or equal to the second threshold, otherwise perform detection according to the fourth WUS.

[0279] That is, in the embodiment of the present invention, when the signal is poor, or the terminal is in the coverage enhancement mode with a relatively low configuration, the third WUS is sent through the basic unit in the second sending method so that the terminal can receive the WUS.

[0280] The first signaling in the embodiment of the present invention is: the first enabling signaling.

[0281] That is, the terminal determines the specific detection method according to the grouped WUS enabling signaling.

[0282] In the fourth detection method in the embodiment of the present invention, the second signaling includes at least one of the following: the maximum number of groups corresponding to the fifth WUS, the minimum number of groups corresponding to the fifth WUS, the number of groups corresponding to the fifth WUS, and the interval for changing the number of groups corresponding to the fifth WUS.

[0283] That is to say, all the WUSs received by the fourth detection method in the embodiments of the present invention are grouped WUSs.

[0284] In the embodiments of the present invention, the first detection method determines the preset basic unit through signaling indication or presetting.

[0285] It should be noted that the basic unit in the embodiments of the present invention is M POs, N discontinuous reception DRX cycles, P enhanced discontinuous reception eDRX cycles, or K radio frames, where M, N, P, and K are positive integers greater than 0 respectively.

[0286] Specifically, the terminal in the embodiments of the present invention analyzes the basic unit sent by the terminal according to the rules predetermined with the base station to obtain the WUS, and determines whether to receive and analyze the PDCCH according to the WUS.

[0287] Generally speaking, the detection unit 42 in the embodiments of the present invention detects the received WUS according to the grouping rules predetermined with the base station, so as to determine whether to receive the PDCCH / PDSCH. Since the WUS sent by the base station is sent in groups, the terminal in the embodiments of the present invention can effectively avoid unnecessary steps of detecting the PDCCH, thus saving the power consumption of the terminal.

[0288] The seventh embodiment of the present invention provides a base station, which includes any one of the WUS sending devices in the fifth embodiment of the present invention. For details, please refer to the fifth embodiment of the present invention, and no detailed description will be given here.

[0289] The eighth embodiment of the present invention provides a terminal, which includes any one of the WUS detection devices in the sixth embodiment of the present invention.
