Description

Method and device for determining and indicating wake-up signal resource, terminal and base station

Technical Field

The invention relates to the technical field of wireless communication, in particular to a method and a device for determining and indicating wake-up signal resources, a terminal and a base station.

Background

Along with the rise of the intelligent terminal, the terminal functions are more and more powerful, the power consumption of the terminal also more and more influences the user experience, and the energy-saving requirement of the user on the terminal is more and more strong.

Therefore, in The Fifth-Generation mobile communication (5G) New Radio (NR, also called New air interface) technology, a paging (paging) mechanism introduces a Wake Up Signal (WUS) mechanism to save energy consumption. Because the power consumption for detecting the wake-up signal is far lower than that for detecting a Physical Downlink Control CHannel (PDCCH for short), the wake-up signal is used to indicate whether a User Equipment (UE for short) needs to listen to the PDCCH at a corresponding paging occasion (PO for short), thereby achieving the purpose of saving energy consumption.

In an existing Long Term Evolution (LTE) wake-up signal mechanism, each PO has a wake-up signal located at a specific time domain position and is associated with the PO. Wherein, the wake-up signal has a certain transmission duration (duration) in the time domain. If the wake-up signaling mechanism in NR is similar to that in LTE, a lot of time resources will be consumed in the time domain. Considering the shortage of NR resources, it is difficult to find enough idle downlink time domain resources to transmit the wake-up Signal, and thus, transmitting the wake-up Signal may cause resource collision between the wake-up Signal and a Synchronization Signal Block (SSB), or resource collision between the wake-up Signal and a PO, or collision between wake-up signals associated with different POs.

Therefore, how to reduce the time domain resources occupied by the wake-up signal and avoid resource collision as much as possible is one of the technical problems to be solved urgently.

Detailed Description

As mentioned in the background, in LTE, each PO is configured with a wake-up signal using different time domain resources, which have high overhead and are difficult to be directly applied to NR communication.

Specifically, a Radio Resource Control IDLE-IDLE (RRC-IDLE for short) terminal consumes a large amount of power in a cell reselection measurement process and a paging PDCCH monitoring detection process. Wherein, the power consumption for monitoring the paging PDCCH is larger. For this reason, LTE introduces a Wake Up Signal (WUS) with low power consumption for power consumption of Machine-type communication (MTC) terminals and narrowband Internet of Things (NB-IoT) terminals to indicate whether the terminal monitors PDCCH.

Those skilled in the art understand that an IDLE (i.e., RRC-IDLE) terminal mainly monitors a paging PDCCH, and a CONNECTED (RRC-CONNECTED) terminal mainly monitors a PDCCH for uplink and downlink data scheduling. Since the time that the terminal is in the idle state is longer than the time that the terminal is in the connected state, LTE focuses on the idle state terminal to monitor the paging PDCCH when designing the wake-up signal.

The paging message mainly has the following functions: (1) sending a call request to the UE in an idle state; (2) informing the UE in an idle state, an INACTIVE state (RRC-INACTIVE) and a connected state, and updating system information; (3) an Earthquake and Tsunami notification, which indicates that the UE receives an Earthquake and Tsunami Warning System (ETWS) primary (primary) notification and/or an ETWS secondary (secondary) notification; (4) the UE is instructed to receive Commercial Mobile Alert System (CMAS) notifications. And if the UE is paged or the system information is updated or an earthquake and tsunami occur, the base station sends a wake-up signal to the idle UE. After the UE detects the wake-up signal, whether a paging PDCCH is monitored to receive a paging message is determined according to the wake-up signal; if the UE does not have to monitor the paging PDCCH, the UE can continue to stay in the sleep state to save energy consumption.

As mentioned above, in the LTE wake-up signal mechanism, each PO is associated with a wake-up signal. Since the PO is time-divided, the wake-up signal is also time-varying. The wake-up signal is usually located before the PO, and there is a fixed non-zero time interval between the wake-up signal and the PO start position. The start position of the time interval ends the position calculation with the configured maximum wake-up signal duration. In actual transmission, the wake-up signal is not of a fixed duration, a base station on the network side starts transmission from a start position of a configured maximum wake-up signal duration, a single subframe is used as a basic unit, the wake-up signal transmission is completed by repeating or expanding a plurality of subframes, and the UE monitors the wake-up signal according to 2 power-of-power subframes.

With the increasing demand for power saving of 5G terminals, the 3rd generation Partnership Project (3 GPP) working group establishes that the meeting is performed in the 80 th meeting (RAN #80 for short) of a Radio Access Network (RAN): research is directed to a power saving mechanism of a future NR 16 version (Release 16, abbreviated as R16) Mobile BroadBand enhanced (eMBB) terminal to improve user experience.

Specifically, the NR system introduces the concept of "partial Bandwidth" (BWP), which requires that idle UEs can only operate in the initially active BWP, and the Bandwidth of the initially active BWP can ensure that all Bandwidth-capable UEs can normally receive data in the initially active BWP. The idle-state UE can only listen to the paging PDCCH and receive paging messages on the initially activated BWP.

In the NR system, the UE may reduce power consumption using Discontinuous Reception (DRX) in an idle state and an inactive state. The UE listens to the PO for each DRX cycle. Since NR introduces the operation of beam management, the length of each PO is equal to one beam scanning period. The base station repeatedly transmits the same paging message in all beams of the scanning pattern, and the UE receives the paging message of which beam depending on the UE itself. Each Paging Frame (PF) may contain one or more POs, or the PF may be represented as a starting point of a single PO.

In NR systems, the transmission resource varies with different Sub-Carrier spacing (SCS), and the PO duration depends on the SCS and the number of beams in the beam sweep. The NR configures the PO using a paging search Space (pagengsearch Space). When multiple beams are used to transmit NR paging, the PO consists of a set of PDCCH listening instants (e.g., one for each beam), and the number of PDCCH listening instants in the PF is typically indicated with a parameter Ns.

In addition, in order to flexibly and effectively configure the POs and avoid occurrence of redundant PDCCH monitoring time, the base station may display a first PDCCH monitoring time indicating each PO and configure the PDCCH monitoring time of each PO. Explicitly indicating the starting position of the PO will ensure that the UE ignores any extra PDCCH listening occasions and only listens to the PDCCH for the desired period of time, i.e. during a valid PO.

Fig. 1 is a schematic diagram of a typical application scenario of PF and PO configuration in an NR system. Wherein, the parameter firstdcch-monitoringOccasionoOfPO can indicate the first PDCCH interception time of each PO and can know the starting position of the multiplexed PO. For example, the 1 st value is 0, indicating the starting position of paging occasion 1 (i.e., PO 1); the 2 nd value is 15, indicating the starting position of paging occasion 2 (i.e., PO 2); a value of 3 is 30 indicating the starting position of paging occasion 3 (i.e., PO 3); the 4 th value is 45 indicating the starting position of paging occasion 4 (i.e., PO 4). Based on the parameter firstdcch-MonitoringOccasionOfPO, the base station can configure the time interval of the adjacent two POs. Wherein the number of PDCCH listening time instants per PO depends on the number of SSB beams transmitted by the SSB burst set. The parameter firstdcch-MonitoringOccasionOfPO may determine the potential individual PDCCH listening instants as one or more PDCCH listening instant sets or one PDCCH listening instant "burst (burst)", in combination with the number of beams used for paging transmission. Based on the parameter configuration, the time interval between two adjacent POs in each PF is variable. It can be seen that the PO configuration mechanism of NR is already different from that of LTE.

Further, if NR configures one associated wake-up signal for each PO according to the existing LTE wake-up signal mechanism, it will consume a lot of time resources to transmit the wake-up signal. Due to the shortage of time domain resources in NR, this may cause resource collision of the wake-up signal with SSB during transmission; alternatively, the wake-up signal may collide with the PO transmission resource. Still alternatively, under a specific PF and PO parameter configuration, the time interval between POs and PO is very small, even no time interval, and at this time, a problem that wake-up signals collide with each other may occur.

In order to solve the foregoing technical problem, an embodiment of the present invention provides a method for determining a wake-up signal resource, where the method for determining includes: receiving a wake-up signal indication parameter sent by a network side, wherein the wake-up signal indication parameter indicates one or more of the following items of information: the number of paging occasions contained in the paging time set, the type of the association relationship between the wake-up signal and each paging occasion in each paging time set, wherein the type of the association relationship is as follows: the wake-up signal is associated with the paging occasion in a one-to-one way or the wake-up signal is associated with the paging occasion in a one-to-many way; and extracting the value of the wake-up signal indication parameter to determine the resource configured by the wake-up signal.

By the technical scheme provided by the embodiment of the invention, the network side can flexibly configure the wake-up signal resource according to the use condition of the wireless resource, the user equipment can know the type of the association relation between the wake-up signal and each paging occasion in the unit during paging according to the received wake-up signal indication parameter, so that the time domain resource used by the wake-up signal associated with each paging occasion is obtained, the time domain resource overhead caused by the wake-up signal is reduced, and the resource collision problem can be effectively avoided.

Furthermore, the user equipment can know whether the PDCCH corresponding to the paging occasion needs to be detected or not after the wake-up signal is detected, so that the detection quantity of the PDCCH can be reduced, and the power consumption of the terminal is further reduced.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 2 is a flowchart illustrating a method for determining a wake-up signal resource according to an embodiment of the present invention. The determination method may be applied to the user equipment side, for example, performed by the UE. Specifically, the determination method may include the steps of:

step S201, receiving a wake-up signal indication parameter sent by a network side, where the wake-up signal indication parameter indicates one or more of the following items of information: the number of paging occasions contained in the paging time set, the type of the association relationship between the wake-up signal and each paging occasion in each paging time set, wherein the type of the association relationship is as follows: the wake-up signal is associated with the paging occasion in a one-to-one way or the wake-up signal is associated with the paging occasion in a one-to-many way;

step S202, extracting the value of the wake-up signal indication parameter to determine the resource configured by the wake-up signal.

More specifically, in step S201, the UE may receive a wake-up signal indication parameter transmitted by the network side.

In a specific implementation, the network side may send the wake-up signal indication parameter by using a higher layer signaling. The high-level signaling may be Mobility Management Entity (MME) signaling, Access Stratum (AS) signaling, or Non-Access Stratum (NAS) signaling.

In a specific implementation, the wake-up signal indication parameter may indicate the following information: the number of paging occasions contained in the paging time set, and the type of the association relationship between the wake-up signal and each paging occasion in each paging time set.

In a specific implementation, the base station on the network side may determine the type of association relationship between the wake-up signal and the paging occasion according to the transmission resource. The type of the association relationship can be one-to-one association between the wake-up signal and the paging occasion; alternatively, the type of the association relationship may be one-to-many association of the wake-up signal and the paging occasion.

As a non-limiting example, the base station may divide consecutive POs in each PF into a PO group according to the PFs, the PO-related parameters, and the time-frequency resource utilization, where each PO group is associated with one or more wake-up signals of the same time-domain resource. The one or more wake-up signals are located in the same time domain resource, e.g., in the same wake-up signal detection window.

Let M' denote the wake-up signal indication parameter. In order to enable the UE to know the resource configuration of the wake-up signal and the association relationship between the wake-up signal and the PO, the base station may send the value of the parameter M 'to the UE, so that the UE may obtain the resource configuration information of the wake-up signal, the number of POs included in the PO group, and the type of the association relationship between the wake-up signal and the PO according to the value of the parameter M'.

As a non-limiting example, table 1 shows the values of the parameter M 'and the number of POs contained in a group of POs when each PF contains 4 POs, and the type of association between the PO and the wake-up signal indicated by the parameter M'. Those skilled in the art will appreciate that, taking table 1 as an example, the PO group may include 1, 2 or 4 paging occasions. In table 1, the parameter M' has 5 values, and may be represented by 3 bits, and redundant bit values may be reserved bits. For example, "000" represents 0, "001" represents 1, etc., which are not described in detail herein.

TABLE 1

In step S202, the UE may extract the value of the wake-up signal indication parameter, so as to obtain a resource configured by the wake-up signal according to the value of the wake-up signal indication parameter, and receive the wake-up signal at the wake-up signal resource.

In a specific implementation, the UE may obtain the number of paging occasions included in each paging time group (i.e., PO group) according to the value of the wake-up signal indication parameter. Then, the UE may obtain the paging occasions included in each paging occasion group based on the time domain positions of the paging occasions in the paging frame configured by the network side and the number of the paging occasions. After the number of paging occasions in each paging time group is known, the UE can obtain the association relationship between the wake-up signal and each paging occasion in each paging time group by combining the type of association relationship between the wake-up signal indicated by the wake-up signal indication parameter and each paging occasion in each paging time group, so as to obtain the wake-up signal resource.

As a non-limiting example, when the UE receives the wake-up signal indication parameter, it can know the type of the association relationship and know the association relationship between the wake-up signal and the paging occasion. Moreover, the UE can know the time domain position of each paging occasion configured for the UE itself by the network side from the configuration information transmitted by the network side in advance. And the network side transmits the wake-up signal based on available time-frequency resources. The available time frequency resources refer to idle time domain resources which can be used for transmitting the wake-up signal when the base station on the network side transmits the wake-up signal. And when the wake-up signal is transmitted, the idle time domain resource is not overlapped with the SSB and the paging occasion resource.

Those skilled in the art understand that when the idle time domain resources are in short, the number of the wake-up signals may be reduced, and at this time, the base station may configure the type of the association relationship as one-to-many association between the wake-up signal and the paging occasion, so as to avoid resource collision between the wake-up signal and the wake-up signal.

After determining the time domain resource of the wake-up signal, the UE further needs to receive the wake-up signal in the time domain resource. In specific implementation, the UE may configure, according to the starting time Tpo of each paging time group, the duration Tw of the wake-up signal detection window, and the gap Tgap between the paging time group and the wake-up signal detection window, at the network side. The parameters Tpo, Tw, and Tgap are determined by the network side (e.g., the base station) and the UE through negotiation in advance, or the base station notifies the UE in advance. After knowing the values of the parameters Tpo, Tw, and Tgap, the UE may obtain a starting transmission time Twus of the wake-up signal detection window, and receive the wake-up signal at the starting transmission time Twus.

It should be noted that, when the same time domain resource transmits multiple wake-up signals, the base station may transmit each wake-up signal in a frequency division multiplexing or code division multiplexing manner, and accordingly, the UE may receive each wake-up signal in a frequency division multiplexing or code division multiplexing manner.

Fig. 3 is a schematic diagram illustrating an association relationship between a PO group and a wake-up signal according to an embodiment of the invention. Referring to fig. 3, assuming that all POs of the PF are divided into two groups of POs (e.g., PO group 1 and PO group 2), the time interval of the wake-up signal detection window associated with PO group 1 is Gap0, and the time interval of the wake-up signal detection window associated with PO group 2 is Gap 1. The UE may know the values of Gap0 and Gap1, the duration of the wake-up signal detection window, and the start time positions of PO group 1 and PO group 2 in advance from the base station, and thus, the UE may know the start time positions of the wake-up signal detection. Assuming that the start position of PO group 1 is Tpo1, the wake-up signal detection window size is twinow, and the time interval between the end time point of the wake-up signal detection window and the start time point of PO group 1 (i.e. Gap0) is TGap, the detection start time position Twus of the wake-up signal associated with PO group 1 is Tpo 1-TGap-twinow.

In one embodiment, when each PO group includes a plurality of POs, the wake-up signal may be a plurality of POs. At this time, to identify the wake-up signals associated with different POs, the base station may transmit a plurality of wake-up signals in a frequency division multiplexing or code division multiplexing manner at the initial transmission time Twus. Correspondingly, after knowing the initial sending time Twus, the UE receives the plurality of wake-up signals in a frequency division multiplexing or code division multiplexing manner.

As a non-limiting example, taking the parameter M' in table 1 as an example, assuming that there are 4 POs in the PF, fig. 4 shows a schematic diagram of an association relationship between a PO group and a wake-up signal according to an embodiment of the present invention. As can be seen from table 1 and fig. 4, when the time interval between two consecutive POs in the PF is large, the network side may indicate that the parameter M' is 1 through high-layer signaling, and the type of the association relationship between the wake-up signal and the PO is one-to-one association.

At this time, as can be seen from table 1, the POs in the PF are divided into 2 groups, each PO group consisting of 2 consecutive POs. Each PO group associates a set of wake-up signals at a specific time domain location. The base station transmits the wake-up signal of the same time domain position by adopting a frequency division multiplexing mode. If the UE needs to receive PO1 (P1 in the figure) and/or PO2 (P2 in the figure), the corresponding wake-up signal detection window can be known by the start time position of PO1 and Gap0, and the corresponding wake-up signal Frequency position can be obtained by the Offset Shift and start Frequency Offset (Frequency start Offset). In fig. 4, PO1 and PO2 form the first PO group, where the wake-up signal 1 (indicated by "1" in the figure) is associated with PO1 and the wake-up signal 2 (indicated by "2" in the figure) is associated with PO 2.

If the UE needs to receive a PO in the second PO group (e.g., PO3 denoted by P3, PO4 denoted by P4, and PO3 and PO4 forming the second PO group), the wake-up signal 3 (denoted by "3" in the figure) is associated with PO3, and the wake-up signal 4 (denoted by "4" in the figure) is associated with PO 4. Then the UE can obtain its corresponding wake-up signal detection window through the start time position of PO3 and Gap1, which is not described herein again.

As another non-limiting example, still taking the parameter M' in table 1 as an example, assuming that there are 4 POs in the PF, fig. 5 shows a schematic diagram of the relationship between a PO group and a wake-up signal according to another embodiment of the present invention. As can be seen from table 1 and fig. 5, when a plurality of POs in a PF are closely adjacent in the time domain, in order to prevent collision between wake-up signals of different PO associations and wake-up signals and SSBs, a base station may divide all POs in the PF into a PO group, where the PO group includes POs PO1, PO2, PO3 and PO4, and may send a group of wake-up signals associated with each PO in the PO group on a specific time domain resource according to a value of Gap0 between an end time point of a wake-up signal detection window and a start time point of the PO group (i.e., a start position of PO1 (indicated as P1 in the figure), and indicate a parameter M' 2 through high layer signaling.

At this time, all POs in the PF are divided into a group of POs (e.g., wake-up signals associated with different POs in the group of POs are transmitted in a frequency division multiplexing manner, and have the same time domain location, i.e., wake-up signal 1 is associated with PO1, wake-up signal 2 is associated with PO2, wake-up signal 3 is associated with PO3, and wake-up signal 4 is associated with PO4), and are associated with a group of wake-up signals at the same time domain location. In the figure, "1" represents a wake-up signal 1, "2" represents a wake-up signal 2, "3" represents a wake-up signal 3, and "4" represents a wake-up signal 4; "P1" represents PO1, "P2" represents PO2, "P3" represents PO3, and "P4" represents PO 4. Reference may be made to fig. 4 for time domain position calculation of the wake-up signal, and a description thereof will not be repeated.

As another non-limiting example, still taking the parameter M' in table 1 as an example, assuming that there are 4 POs in the PF, fig. 6 shows a schematic diagram of the relationship between a PO group and a wake-up signal according to another embodiment of the present invention. As can be seen from table 1 and fig. 6, when the time-frequency resource of the system is tight and a plurality of continuous POs in the PF are closely adjacent, the base station may indicate to the UE that the value of the parameter M 'is 3, that is, indicate the UE through the value of the parameter M', and the wake-up signal and the POs are in a two-to-one association relationship.

At this time, as can be seen from table 1, all POs (e.g., PO1, PO2, PO3, PO4) in the PF are divided into a PO group, and are associated with a group of wake-up signals at the same time domain location (e.g., different wake-up signals in the group are transmitted by frequency division multiplexing). In this case, each wake-up signal in the wake-up signal group is associated with 2 POs, i.e., PO1 and PO2 are associated with WUS wake-up signal A, and PO3 and PO4 are associated with WUS wake-up signal B. In the figure, "a" represents a wake-up signal a, and "B" represents a wake-up signal B; "P1" represents PO1, "P2" represents PO2, "P3" represents PO3, and "P4" represents PO 4. Reference may be made to fig. 4 for time domain position calculation of the wake-up signal, and a description thereof will not be repeated.

As another non-limiting example, still taking the parameter M' in table 1 as an example, assuming that there are 4 POs in the PF, fig. 7 shows a schematic diagram of another association relationship between a PO group and a wake-up signal according to an embodiment of the present invention. Here, a plurality of wake-up signals transmitted by the same time domain resource are transmitted based on a code division multiplexing manner, and at this time, the association relationship between the wake-up signals and the PO and the resource configuration manner of the wake-up signals are both consistent with the above embodiments based on frequency division multiplexing.

In an implementation, combining table 1 and fig. 7, when a plurality of POs in a PF are closely adjacent in the time domain, the base station may divide all the POs in the PF into a PO group, for example, the PO group includes each PO, which is PO1, PO2, PO3 and PO 4. The wake-up signals associated with different POs in the PO group are transmitted in a code division multiplexing manner, and the time domain positions of the wake-up signals are the same, i.e. the wake-up signal 1 is associated with the PO1, the wake-up signal 2 is associated with the PO2, the wake-up signal 3 is associated with the PO3, and the wake-up signal 4 is associated with the PO 4. In the figure, "1" represents a wake-up signal 1, "2" represents a wake-up signal 2, "3" represents a wake-up signal 3, and "4" represents a wake-up signal 4; "P1" represents PO1, "P2" represents PO2, "P3" represents PO3, and "P4" represents PO 4. Reference may be made to fig. 4 for time domain position calculation of the wake-up signal, and a description thereof will not be repeated.

Fig. 8 is a flowchart illustrating a method for indicating wake-up signal resources according to an embodiment of the present invention. The indication method can be applied to the network side and is implemented by network side equipment. Specifically, the indication method may include the steps of:

step S801, determining a wake-up signal indication parameter, where the wake-up signal indication parameter indicates one or more of the following items of information: the number of paging occasions contained in the paging time set, the type of the association relationship between the wake-up signal and each paging occasion in each paging time set, wherein the type of the association relationship is as follows: the wake-up signal is associated with the paging occasion in a one-to-one way or the wake-up signal is associated with the paging occasion in a one-to-many way;

step S802, sending the wake-up signal indication parameter to the user equipment.

More specifically, a network side device (e.g., a base station) may configure resources used by the PF, PO, wake-up signal, and wake-up signal for the UE. And, the association relationship between the wake-up signal and the PO is also determined and configured to the UE by the base station.

In step S801, the base station on the network side may determine the value of the wake-up signal indication parameter. The wake-up signal indication parameter may indicate the following information: the number of paging occasions contained in the paging time set, the type of association relationship between the wake-up signal and each paging occasion in each paging time set, and the like. The type of the association relationship may be: the wake-up signal is associated one-to-one with the paging occasion or the wake-up signal is associated one-to-many with the paging occasion.

In a specific implementation, after determining the number of paging occasions included in the paging time group, the base station may determine the number of paging occasions included in each paging time group according to the time domain position of each paging occasion in the paging frame and the number of paging occasions. The paging time group may include 1, 2 or 4 paging occasions.

Then, the base station can determine the association relationship between the wake-up signal and the paging occasions according to the time domain position of each paging occasion and available time frequency resources, and determine the value of the wake-up signal indication parameter according to the number of the paging occasions and the association relationship. The available time frequency resource refers to a time frequency resource which can be used for transmitting the wake-up signal and is not overlapped with the SSB, the resource occupied by the paging occasion and the resource occupied by the uplink transmission when the wake-up signal is transmitted. It should be noted that the uplink transmission occupied resource refers to a resource for uplink transmission (e.g., uplink control signaling and uplink data).

In step S802, the base station may transmit the value of the parameter to the user equipment. For example, the wake-up signal indication information may be sent to the user equipment through higher layer signaling such AS MME signaling, AS signaling, NAS signaling, and the like.

And then, the network side can also transmit each wake-up signal on the determined wake-up signal resource through the base station. Specifically, the base station may determine a start time Tpo of each PO group, a duration Tw of a wake-up signal detection window, and a gap Tgap between the PO group and the wake-up signal detection window; and determining a starting sending time Twus of the wake-up signal detection window by using a formula Twus-Tpo-Tgap, and transmitting the wake-up signal at the starting sending time Twus. If the PO group includes a plurality of paging occasions and the number of wake-up signals is multiple, the base station may transmit the plurality of wake-up signals in frequency division multiplexing or code division multiplexing manner at the initial transmission time Twus.

Those skilled in the art will understand that the steps S801 to S802 may be regarded as execution steps corresponding to the steps S201 to S202 described in the above embodiment shown in fig. 2, and the two steps are complementary in terms of specific implementation principle and logic. Therefore, the indication method of the wake-up signal resource on the network side may refer to the related description of the embodiments shown in fig. 2 to fig. 7, and is not described herein again.

In summary, according to the technical solution provided by the embodiment of the present invention, the POs in the same PF are grouped, and the wake-up signal indication parameter is used to indicate the number of POs in each PO group and the type of association relationship between the wake-up signal and the PO, so that each PO in the PO group is associated with a plurality of wake-up signals in a specific time domain position. Based on the technical scheme provided by the embodiment of the invention, the base station can flexibly configure the wake-up signal resource, and the problems of time domain resource shortage in NR and resource collision caused by introduction of the wake-up signal are well solved. In addition, the number of the wake-up signals can be reduced by flexibly configuring the one-to-many association relationship between the wake-up signals and the POs, so that the system resource overhead caused by introducing the wake-up signals is reduced.
