The configuration method leads to a problem of low resource configuration flexibility and improves resource configuration flexibility.

The following describes this embodiment by taking specific optional embodiments and examples as examples.

This optional embodiment proposes a method for sending a signal, including: setting a power saving state, and configuring a terminal that temporarily has no need for service transmission to a power saving state. In the power saving state, the terminal does not need to listen to the WUS and Signals and channels other than at least one of the WUPs, thereby achieving the effect of saving energy consumption; when the service of a terminal arrives, the network side wakes up the terminal through at least one of the WUS and the WUP. Under such a mechanism, the terminal and the network side need to have a unified understanding of at least one of WUS and WUP transmission; otherwise, the network side cannot effectively wake up the designated terminal. Therefore, for different terminals, how to determine the time-frequency resource location of at least one of the WUS and WUP corresponding to it is a problem to be solved.

The downlink transmission used to wake up the terminal may include only WUS, for example, a sequence carried at a specified time-frequency location is used to wake up the corresponding terminal; or it may only include WUP, that is, a physical downlink control channel carried at a specified time-frequency location ( Physical Downlink Control Channel (PDCCH) to wake up the corresponding terminal; or, use a combination of WUS and WUP to wake up a specific terminal together. In the above three methods, the network side only sends WUS, or only WUP, or WUS and WUP. Further, the WUS may include one or more levels of signals, and the WUP may include one or more levels of PDCCH.

Optional embodiment 1

This optional embodiment describes a method for determining a carrier where at least one of WUS and WUP is located. The carrier can also be called a component carrier (Component Carrier, CC) or a cell.

When a UE is configured with multiple carriers, the carrier transmitting at least one of the WUS and WUP is determined in the following manner:

Sub-example 1.1

At least one of WUS and WUP is fixed and transmitted on the UE's main carrier (also referred to as Pcell).

Sub-example 1.2:

At least one of WUS and WUP is transmitted on a configured carrier.

Before the terminal enters the energy-saving state, the network side configures the terminal. After entering the energy-saving state, at which moment on which carrier is listening at least one of WUS and WUP, at this time, the network side can be in the active state when the UE enters the energy-saving state One or more carriers in the multiple carriers are configured as a carrier transmitting at least one of WUS and WUP; or, the network side pre-configures one or more carriers as transmitting at least one of WUS and WUP. In this configuration mode, the carrier is not limited to the carrier that is in the active state when entering the energy-saving state.

The network side may configure a carrier carrying at least one of the WUS and WUP to the terminal through any of the following signaling: (Radio Resource Control (RRC) signaling, Media Access Control (MAC) Control element (CE) CE, physical layer signaling (such as Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), etc.).

Sub-example 1.3

At least one of WUS and WUP is transmitted on a carrier calculated in a predefined manner.

In this way, the correspondence between the UE and the CC needs to be defined, for example, the mapping between the UE ID and the carrier index (CC index); specifically, the CC index carrying at least one of WUS and WUP can be modified by the 'UE ID' mod The “Number of CCs” is determined, wherein the UE ID may be an identity of the terminal in the cell, that is, a Cell Radio Network Temporary Identifier (CRNTI), or an International Mobile Subscriber Identifier (IMSI) . CC index can be used to number multiple carriers that are in the active state when the UE enters the energy-saving state to obtain the CC index corresponding to each carrier; or to number the multiple carriers configured on the network side to obtain the corresponding number of each carrier CC index, in this configuration mode, it is not limited to the carriers that are in the active state when entering the energy-saving state.

Sub-example 1.4:

WUS and WUP are on different carriers, and WUS is used to indicate the carrier on which the WUP is located.

The carrier on which the WUS is located can be determined by the methods described in the above sub-examples 1.1, 1.2, and 1.3; and, the carrier on which the WUP is located is indicated by using the WUS.

Specifically, the mapping relationship between the characteristics of the WUS and the carrier where the WUP is located is defined, and the carrier where the WUP is located is indicated by transmitting a WUS sequence with the specified characteristics. Wherein, the characteristics of the WUS include at least one of the following: different WUS sequence indexes, root sequence indexes of WUS sequences, time domain positions of WUS sequences, frequency domain positions of WUS sequences, different cyclic shift amounts of WUS sequences, and WUS The length of the sequence.

For example, Table 1 shows a mapping relationship between a predefined WUS feature and the carrier where WUP is located. Among them, the WUS feature includes a WUS root sequence index and different cyclic shift amounts of the WUS sequence. The index of the carrier where the WUP is located can be determined by referring to the method described in Sub-Example 1.3.

When the UE detects that the current WUS root sequence index is 1 and the cyclic shift is 34 at the specified time-frequency position, it is determined that the subsequent WUP will be transmitted on carrier 1.

In this way, the carrier position of the WUP can be indicated by the transmission of the WUS signal, and the carrier position of the WUP may be the same as the carrier used for subsequent data transmission, thereby enabling the terminal to switch to the correct carrier more quickly.

Table 1

Sub-example 1.5

At least one of WUS and WUP is carried at an absolute frequency point, for example, some absolute frequency points are defined for the transmission of at least one of WUS and WUP, and the center or boundary of at least one of WUS and WUP is located at the absolute frequency On the point, before entering the energy-saving state, the network side can indicate the absolute frequency point to the terminal. This absolute frequency may not belong to a carrier.

Optional embodiment 2

This alternative embodiment describes which carriers are activated by at least one of WUS and WUP.

When the terminal detects at least one of WUS and WUP, it will transition from the energy-saving state to the normal working state. For a terminal configured with multiple carriers, it is necessary to determine which carriers to activate.

Sub-example 2.1

After the UE is awakened, only the carrier carrying at least one of WUS and WUP is activated. For example, when at least one of WUS and WUP is transmitted on Pcell, after receiving at least one of WUS and WUP, only Pcell Activated, use other signaling in Pcell to reactivate other carriers.

Subexample 2.2

Considering the deactivation timers of different cells, after entering the sleep state, even if the "sCellDeactivationTimer" (this timer is used, when a cell is not scheduled within the time set by the timer, the cell (Deactivated) has not timed out, but all carriers should also be deactivated. At this time, equivalent to the terminal entering the energy-saving state is a trigger factor for carrier deactivation.

When the UE is woken up again, the carrier transmitting at least one of WUS and WUP is activated, the carrier whose timer has not expired is activated at the same time, and the timer continues to count. That is, when the terminal enters the energy-saving state, the non-timeout timer is suspended, and after the terminal resumes the normal communication state, the timer continues to accumulate.

Subexample 2.3

Considering the deactivation timers of different cells, after entering the sleep state, even if the "timer sCellDeactivationTimer" has not timed out, all carriers should be deactivated. At this time, the equivalent of the terminal entering the energy-saving state is a trigger for carrier deactivation. .

When the UE is woken up again, the carrier transmitting at least one of WUS and WUP is activated, the carrier whose timer has not expired is activated at the same time, and the timer is reset. That is, when the terminal enters the energy-saving state, the non-timeout timer is reset, and after the terminal resumes the normal communication state, the timer restarts counting.

Subexample 2.4

The carrier on which the WUS is located can be determined by the methods described in the above sub-examples 1.1, 1.2, and 1.3; and, the carrier on which the WUP is located is indicated by using the WUS. At this time, the carrier on which WUP is located is the carrier to be activated.

Specifically, the mapping relationship between the characteristics of the WUS and the carrier where the WUP is located is defined, and the carrier where the WUP is located is indicated by transmitting a WUS sequence with the specified characteristics. The characteristics of the WUS include at least one of the following: different WUS sequence indexes, WUS sequence root sequence indexes, time domain positions of the WUS sequences, frequency domain positions of the WUS sequences, different cyclic shift amounts of the WUS sequences, and WUS The length of the sequence.

Optional embodiment 3

This optional embodiment describes a method for determining at least one of WUS and WUP where the BWP is located and the relative position within the BWP.

Each carrier can be further divided into several BWPs, and the BWPs can be cell-level (that is, common to all UEs in the cell) or UE-level. The BWP where at least one of WUS and WUP is located, and the relative position of at least one of WUS and WUP within the BWP are determined in one of the following ways:

Sub-example 3.1

A BWP is specifically configured for at least one of WUS and WUP, that is, "the exclusive BWP of at least one of WUS and WUP". At this time, the frequency position and bandwidth of BWP are the frequency position of at least one of WUS and WUP And bandwidth.

The "at least one of WUS and WUP exclusive BWP" has a frequency domain position that is predefined by the system or is semi-statically configured by the network side.

Specifically, at least one of the following information can be configured: absolute frequency domain position (can be indicated by absolute radio frequency channel number (ARFCN, Absolute Radio Frequency Channel Number)), bandwidth (can be indicated by RB granularity), subcarrier interval (Such as 15kHz, 30kHz, 60kHz, 120kHz, 240kHz, etc.), cyclic prefix CP type (including normal CP and extended CP two types).

In this way, no matter which BWP the UE activated the Downlink (DL) BWP before entering the energy-saving state, the UE only detects WUS and WUP on "at least one of the WUS and WUP exclusive BWP" At least one of them.

For example, when it is determined that at least one of WUS and WUP is transmitted only on Pcell by using the method in optional embodiment 1, further, "at least one of WUS and WUP exclusive BWP" is configured in Pcell, that is, this At this time, the UE only needs to detect at least one of WUS and WUP on the Pcell, and does not need to detect at least one of the WUS and WUP on other carriers or other BWPs of the Pcell.

Sub-example 3.2

A frequency domain position and a bandwidth for transmitting at least one of WUS and WUP are configured in each BWP.

There are two methods for specific configuration:

Method 1: Each BWP is independently configured with "the frequency domain position of at least one of WUS and WUP in the respective BWP". At this time, "the frequency domain position of at least one of WUS and WUP in the respective BWP may be different.

Within each BWP, the frequency position can be indicated by indicating the offset between the lowest RB boundary occupied by at least one of WUS and WUP and the lowest RB boundary of BWP, and at least one of WUS and WUP can be indicated. One occupied bandwidth. Note, as shown in Figure 3, the bandwidth of WUS and WUP can be different.

Method 2: The relative position of "at least one of WUS and WUP" in one BWP is uniformly configured, that is, the relative position of "at least one of WUS and WUP" in each BWP is the same.

For example, at least one of WUS and WUP occupies a resource with an offset of N from the BWP lowest RB boundary and M consecutive RBs in each BWP. As shown in FIG. 4, in each BWP, at least one of WUS and WUP has the same relative frequency position (including frequency offset and bandwidth) of the BWP in which it is located.

Regardless of method 1 or method 2, the UE may detect at least one of the WUS and WUP in one of the following ways:

Method 1: The BWP will not be switched in the energy-saving state of the UE, then the UE only needs to detect at least one of the WUS and WUP on the "at least one frequency domain position of WUS and WUP" of the BWP that is activated when it enters the energy-saving state. In this way, at least one of WUS and WUP will further instruct the UE which BWPs to activate.

Method 2: The network side only sends at least one of WUS and WUP on the BWP that is expected to be activated. Therefore, the UE needs to detect at least one of WUS and WUP on the "at least one of WUS and WUP resources" of each BWP. First, on which BWP at least one of the WUS and WUP is detected, it knows that it has been woken up and needs to activate the BWP where the WUS is located.

Subexample 3.3

Only at least one of WUS and WUP transmission resources is configured in a specific BWP.

No matter which BWP is the activated BWP before the UE enters the energy-saving state, the UE detects at least one of the WUS and WUP in at least one of the WUS and WUP transmission resources in this particular BWP. The specific BWP may be any one of the following BWPs: a default BWP, a BWP with the smallest index, a BWP with an initial activation, and a BWP with the smallest bandwidth.

Subexample 3.4

The specific BWP corresponding to this UE is related to the UE ID. For example, the BWP index (or BWP identifier) carrying at least one of WUS and WUP can be determined by the 'UE ID' mod 'BWP number', where the UE The ID can be the identity of the terminal in the cell, that is, CRNTI or IMSI.

The number of BWPs may be the number of BWPs configured by the network side for this UE in one carrier. At this time, the BWP index obtained by "UE ID" mod "BWP number". The carrier refers to a carrier carrying at least one of WUS and WUP, and a method for determining the carrier can be obtained in any one of the optional embodiments 1.

For example, for UE1, there are currently four active carriers, and the carrier in at least one of WUS and WUP can be obtained by the method in optional embodiment 1, such as CC1. Three BWP and BWP indexes are configured on CC1. They are 0, 1, 2 respectively. If the UE ID is 01010101, the UE ID mod 3 = 1. That is, the BWP index carrying at least one of WUS and WUP is 1.

Optional Example 4

This optional embodiment describes a method for determining a time domain location of at least one of WUS and WUP.

The time domain location of at least one of WUS and WUP may be explicitly indicated by the network side through RRC signaling, MAC CE signaling, or physical layer signaling, or the time domain of at least one of WUS and WUP There is a predefined mapping relationship between the position and at least one of the specified signal and the specified channel. For example, at least one of the predefined WUS and WUP signals is configured in a synchronization signal physical broadcast channel block (SSB, SS / PBCH block). In the subsequent X timeslot, X is explicitly indicated by the network side through RRC signaling, MAC CE signaling, or physical layer signaling, or is predefined in the protocol. The specified signal channel is not limited to the SSB, but may also be a channel state information reference signal (Channel-information-reference-signal, CSI-RS), a specific type of search space, and the like.

This alternative embodiment focuses on describing the relative time domain position relationship between WUS and WUP.

In this optional embodiment, at least one of the WUS and WUP does not have a beam management function. At this time, it is considered that before receiving the WUS / WUP, the beam management has been completed through a related mechanism. Both WUS and WUP can be coupled into a wake block (Wake block, WU block) and sent at a specified time-frequency resource location.

Sub-example 4.1

The time-frequency resources distinguish different UEs (that is, each UE has different time-frequency resource locations for detecting at least one of WUS and WUP). As shown in FIG. 5, at least one of WUS and WUP constitutes a resource block. We call it WU block. In the frequency domain direction, multiple WU blocks are configured within a carrier or BWP range, and in the time domain direction, multiple WU blocks are also configured. Different UEs have their own corresponding one or more resources to detect WU blocks, and determine whether to be woken up by detecting at least one of WUS and WUP in WU blocks at a specified location.

At this time, the WUS sequence may be UE-specific, that is, in the WUS sequence generation process, the UE ID is used to generate a WUS sequence corresponding to the UE; or the WUS sequence may also be UE group-specific That is, a group of UEs corresponds to one WUS sequence, or the WUS sequence may be common to all UEs, that is, only one WUS sequence is defined in a cell range.

As shown in FIG. 6, it is a relative position relationship between WUS and WUP in a WU block, where the WU block includes M symbols, N RBs, and M and N are integers greater than 0. In each RB, the WUS signals are inserted at regular intervals with a certain density. For example, the WUS signals are inserted at a density of 1/4. That is, there are 3 REs in each RB for mapping the WUS signals. The RBs are distributed at equal intervals. At this time, the length of the WUS sequence is equal to the number of WUS REs, that is, M * N * 3. The remaining REs are used to map WUPs. In this case, WUS can be used as a demodulation reference signal for WUP.

FIG. 7 is another relative positional relationship between WUS and WUP in another WU block, where the WU block includes M symbols, N RBs, and M and N are integers greater than 0. Compared with the manner in which the WUS distributed mapping is in the entire WU block in FIG. 6, the WUS sequence here occupies all the RB resources of P symbols, where 0 <P <M. And the resources occupied by WUS outside the symbol map WUP, and there is no need to insert additional demodulation reference signals in WUP RB, that is, WUP occupies all RE resources in RB.

FIG. 8 is another relative position relationship between WUS and WUP in another WU block, where the WU block contains M symbols and N RBs, and the WUS sequence is mapped into Q Q RBs in which P symbols are concentrated, where: 0 <P <M, 0 <Q <N, M, N, P, and Q are all integers. FIG. 7 is a specific example of M = 3, N = 7, P = 1, and Q = 5. At this time, the bandwidth of the WUS is smaller than the bandwidth of the WUP. On the WUP RB outside the WUS bandwidth, additional mapping and demodulation reference signals are needed, as shown in the dotted RB in FIG. 8. At this time, WUS can be used as the demodulation reference signal of WUP in the corresponding bandwidth.

Sub-example 4.2

In this example, a group of UEs corresponds to a same WU block 1 as a starting point for detecting at least one of WUS and WUP. The position of this starting point WU block is configured by the following parameters: monitoring period, offset, and frequency domain position information. Further, it indicates which WU block resources need to be monitored starting from WU block 1 in each monitoring cycle. The following parameters are configured: frequency domain monitoring range, time domain monitoring range; frequency domain monitoring range can be monitored in the frequency domain. The number of WU blocks is indicated, or it is indicated by the absolute frequency range to be monitored; the time-domain monitoring range may be indicated by the number of WU blocks being monitored in the frequency domain, or the time range to be monitored (such as time The number of slots, the number of subframes, and milliseconds) (as shown in FIG. 9).

In this mode, the WUS is UE-specific, that is, in the WUS sequence generation process, a UE ID is used to generate a WUS sequence corresponding to the UE.

According to the configuration information, the UE finds the monitoring starting point WU block and determines the monitoring range, and then detects WUS on the WU block resources within the monitoring range. If a WUS corresponding to itself is detected in a WU block, the UE is woken up, and Receive WUP further.

Sub-example 4.3

A group of UEs corresponds to the same WU block resource. The UE determines whether to further receive the WUP by detecting the WUS sequence in the WU block at the specified location, and includes the ID information of the wake-up UE in the WUP. The UE is woken up.

The UE ID information may be carried in at least one of the following ways:

The explicit bits of the WUP carry some or all of the UE ID information, for example, a semi-static indication, or a predefined maximum number of UEs for a group of UEs that reuse the same WU block resource. For example, the maximum number of UEs is 8, at this time, 8 bits are used in the WUP to indicate which of a maximum of 8 UEs in the same packet are woken up; each bit in the 8 bits corresponds to a UE, and is set to " The UE corresponding to the 1 ”bit is awakened. When the number of UEs is less than the maximum number, the bit corresponding to no UE is set to“ 0 ”.

Corresponding UE ID information is carried in the corresponding PDSCH. Similar to carrying the UE ID information in WUP, WUP will schedule PDSCH resources, and the UE further reads the PDSCH to determine whether it is woken up.

At this time, WUS can be common to this group of UEs.

Subexample 4.4

In this sub-example, WUS and WUP may not constitute a WU block, but may be transmitted separately. The time-frequency domain location of WUS is configured on the network side, and multiple UEs may reuse the same WUS.

A group of UEs corresponds to the same WUS. The UE determines whether to further receive the WUP by detecting the WUS sequence at the specified position, and the UE that detects the WUS will further receive the WUP.

For different UEs in the same group, the relative positional relationship between WUS and WUP is different. As shown in Figure 10, n UEs reuse the same WUS. After detecting WUS, each UE has its corresponding WUP resource. WUP is received, if it is successfully received, it is considered to be awakened.

At this time, WUS can be common to this group of UEs.

Optional Example 5

This alternative embodiment describes another method for determining the relative position relationship between WUS and WUP. WUS can be multiplexed as a beam management reference signal, and the WUS signal needs to be transmitted using multiple beams.

As shown in FIG. 11, each WUS occupies one symbol resource, and multiple symbols are used to complete WUS transmission in multiple beam directions. The UE completes the beam management by measuring the above WUS, that is, the preferred receiving beam is determined, and the UE is configured with the association relationship between the WUS resource and the feedback resource. The UE is in the received WUS (such as the WUS corresponding to the black beam). Feedback information is sent on the corresponding feedback resource, which is used to instruct the base station to select a downlink beam, which serves as a beam reference when the base station subsequently sends WUPs. There is also a predefined association relationship between the feedback resource and the WUP transmission resource. At this time, WUP no longer needs to adopt the multi-beam transmission mode like WUS, and can send it using a uniquely determined beam (such as a black beam). The terminal may also receive the WUP within the determined WUP transmission resource according to the association relationship between the feedback resource and the WUP transmission resource.

Among them, the WUP transmission resource can be defined as a CORESET. A CORESET is a resource set including a pre-configured quantity symbol and a pre-configured quantity RB. Within the CORESET, there are some candidate locations for the WUP, and the UE blindly detects the WUP at these candidate locations.

Further, the WUS sequence can also be used to indicate the candidate positions of WUP in CORESET; for example, CORESET contains a total of four WUP candidate positions, defines four WUS sequences, each corresponding to four candidate positions, and thus selects the specified WUS sequence To indicate to the UE where the WUP is within CORESET. Alternatively, the WUS time-frequency resource location is used to indicate the candidate location of WUP in CORESET. Similarly, multiple WUS time-frequency resource locations are defined to correspond to the candidate location of WUP in CORESET, respectively, by sending at the specified time-frequency resource location. WUS indicates to the UE the position of WUP in CORESET.

The above set of WUSs may be UE-specific, that is, different UEs correspond to WUSs occupying different time-frequency resource groups, and the WUS sequences may be the same or different.

Alternatively, the above-mentioned group of WUS may be UE-specific or common to all UEs, that is, a group of UEs corresponds to a group of WUSs with the same time-frequency resource, and the WUS sequence is the same. At this time, a mapping rule between "association relationship between WUS resource and feedback resource" and "UE ID" may be predefined (for example, defining an association relationship between two WUS resources and feedback resource, UE ID mod 2 = 0 UE applies the first association relationship, and UE ID 2 mod 1 = 1 applies the second association relationship), or the base station configures different association relationships between different WUS resources and feedback resources for different UEs; Both methods can achieve the reuse of a group of different UEs with the same WUS, which are associated with different groups of feedback resources. At this time, even if two UEs receive WUS in the same beam direction, their feedback resources are not the same, which is convenient for the base station to distinguish different The feedback from the terminal, and for the UE to be truly awakened, send a WUP to the UE on a specific WUP transmission resource.

Alternatively, the above-mentioned group of WUS may be UE-specific or common to all UEs, that is, a group of UEs corresponds to a group of WUSs with the same time-frequency resource, and the WUS sequence is the same. For different UEs, the "association relationship between the WUS resource and the feedback resource" and "the association relationship between the feedback resource and the WUP resource" are the same, and the WUP is further used to indicate which of the UEs in this group are actually woken up. The specific method is the same as that described in Sub-Example 4.3.

Optional Example 6

This optional embodiment describes another method for determining the time domain location of at least one of WUS and WUP;

Compared with optional embodiment 5, as shown in FIG. 12, a second-level WUS is added in this embodiment, wherein the transmission method of the first-level WUS is the same as that of optional embodiment 5, that is, multi-beam transmission is adopted; The level WUS and WUP constitute a WU block, and transmit in a single beam.

The second-level WUS can be used as a WUP demodulation reference signal, and further information can also be indicated to the UE. For example, the first-level second-level WUS collectively indicates the wake-up UE, where the first-level WUS is at the UE group level and wakes up. A group of UEs continue to read the second-level WUS, and the second-level WUS defines multiple sequences to indicate which UEs are actually woken up; as shown in Table 2, three sequences are defined to indicate that the first-level WUS Whether UE1 and UE2 that are triggered to receive the second-level WUS are actually awakened.

Table 2

Second-level WUS sequence

Wake UE

序列1Sequence 1	UE1 UE1

序列2Sequence 2	UE2UE2
序列3Sequence 3	UE1和UE2UE1 and UE2

Similar to the alternative embodiment 5, when the above-mentioned set of first-level WUSs may be UE-specific, that is, different UEs correspond to WUSs occupying different time-frequency resource groups, the WUS sequences may be the same or different.

Alternatively, the above-mentioned group of first-level WUSs may be UE-specific or common to all UEs, that is, a group of UEs corresponds to a group of first-level WUSs of the same time-frequency resource, and the first-level WUS sequences are the same. At this time, a mapping rule between the "association relationship between the first-level WUS resource and the feedback resource" and the "UE ID" may be predefined (for example, defining the association relationship between the two first-level WUS resources and the feedback resource) , UE with ID 2 mod = 0 applies the first association, and UE with ID 2 mod 1 = 2 applies the second association), or the base station configures different first-level WUS resources and feedback resources for different UEs. The above two methods can be used to achieve reuse of a group of different UEs of the same first-level WUS, which are associated with different groups of feedback resources. At this time, even if the two UEs receive the first At the level of WUS, their feedback resources are also different, which is convenient for the base station to distinguish the feedback of different terminals, and for the UE to be truly awakened, send a WUP to the UE on a specific WUP transmission resource.

Alternatively, the above-mentioned group of first-level WUSs may be UE-specific or common to all UEs, that is, a group of UEs corresponds to a group of first-level WUSs of the same time-frequency resource, and the first-level WUS sequences are the same. For different UEs, the "association relationship between first-level WUS resources and feedback resources" and "association relationship between feedback resources and WUP resources" are the same, and WUP further indicates which of the UEs in this group are truly wake. The specific method is the same as that described in Sub-Example 4.3.
