Description

Terminal power saving method and device, first terminal and second terminal

Technical Field

The application belongs to the technical field of communication, and particularly relates to a terminal power saving method and device, a first terminal and a second terminal.

Background

The Sidelink (SL) technology refers to direct data transmission between User Equipments (UEs) without using network side Equipment.

In the 5G system, a Wake Up Signal (WUS) based on PDCCH is introduced in order to further improve the power saving performance of the UE. The role of WUS is to indicate whether the UE needs to listen to the physical downlink control channel (Physical Downlink Control Channel, PDCCH) during the duration (onDuration) of a specific discontinuous reception (Discontinuous Reception, DRX); in the case of no data transmission, the UE may not need to monitor the PDCCH during onDuration, which is equivalent to the UE being in a sleep state in the whole DRX Long cycle (Long cycle), thereby further saving power.

In the related art, the WUS signal is sent to the UE by the network side device, and is used for further power saving of the UE, and the problem of resource collision generally does not occur because the network side device has dedicated control on transmission resources. However, in the SL link, two UEs are in a state of mutually controlling mutual packet transmission, and thus, the configuration of power saving is different from a universal user network interface (Uu) interface. And because the SL interface resource pool has discontinuous characteristics, resource preemption characteristics, and factors such as control of receiving and transmitting priorities of Transmitting (TX) UE or Receiving (RX) UE, the Transmission and the receiving of WUS signals have a plurality of abnormal conditions, so that the UE has poor electricity-saving performance and low Transmission efficiency.

Fig. 2 is one of flow diagrams of a terminal power saving method according to an embodiment of the present application, as shown in fig. 2, where the method includes:

step 201, a first terminal receives configuration information sent by network side equipment or a second terminal; the configuration information is used for indicating that the first terminal is in a target state during the onDuration period of the next DRX cycle under the condition that the first terminal meets a target condition; the target states include: a sleep state or an awake state; the target conditions include: the first terminal does not receive the SL WUS.

It should be noted that the embodiments of the present application may be applied to a scenario in which WUS signal transmission or reception is abnormal in SL communication. Direct signaling and data transmission is performed between the first terminal and the second terminal based on SL technology. The first and second terminals may include, but are not limited to, the types of

first terminals

11 and 12 listed above; the network side devices may include, but are not limited to, the types of network side devices 13 listed above.

Optionally, in the case that the service transmission direction is from the second terminal to the first terminal, the first terminal is the service receiving terminal, and the second terminal is the service transmitting terminal. Or under the condition that the service transmission direction is from the first terminal to the second terminal, the second terminal is the service receiving terminal, and the first terminal is the service sending terminal. It should be noted that, in the embodiment of the present application, the service transmission direction is taken as an example from the second terminal to the first terminal; and the case where the traffic transmission direction is from the first terminal to the second terminal may be referred to as execution.

In practice, in the case where independent DRX and WUS signals are configured in the direction from the first terminal to the second terminal and the direction from the second terminal to the first terminal, the terminal power saving method provided in the embodiment of the present application is executed independently in each of the two directions.

Optionally, the configuration information is used to normalize the behavior of the service receiving terminal, and enable the service sending terminal to know the behavior of the service receiving terminal, so as to ensure that the service receiving terminal and the service sending terminal can take correct consistency processing under the condition of abnormal transmission or reception of the SL WUS signal.

Specifically, the target state indicated in the configuration information is determined, and only one of the sleep state and the awake state is possible. Under the condition that the target state is a dormant state, when the first terminal is in the dormant state, the first terminal does not perform scheduling monitoring and data receiving; and when the target state is the awakening state, the first terminal performs scheduling monitoring and data receiving when the first terminal is in the awakening state.

Optionally, in the case that the traffic transmission direction is from the second terminal to the first terminal, the manner in which the first terminal obtains the configuration information may include at least one of:

mode 1, a first terminal receives configuration information sent by a network side device.

Specifically, the network side device sends configuration information to the first terminal and the second terminal respectively, so that the first terminal and the second terminal receive the consistent configuration information, and then the first terminal and the second terminal are in the same target state during the onDuration period of the next DRX cycle under the condition that the target condition is met. The method can be applied to the scenes of unicast (unicasting), broadcast (broadcasting) or multicast (multicasting) of the PC5, and the network side realizes the consistency of the configuration information obtained by the service receiving terminal and the service transmitting terminal.

Mode 2, the first terminal receives configuration information sent by the second terminal.

Specifically, the second terminal first acquires or determines the configuration information, and then the second terminal sends the configuration information to the first terminal, so that the first terminal and the second terminal have consistent configuration information, and then the first terminal and the second terminal are in the same target state during the onDuration of the next DRX cycle under the condition that the target condition is met. In practice, the second terminal may send the configuration information to the first terminal through the PC5 RRC procedure, that is, the second terminal performs WUS configuration on the first terminal through the PC5 RRC procedure, which may be applied in a PC5 unicast (unicasting) scenario.

In the terminal power saving method provided by the embodiment of the invention, the first terminal receives the configuration information sent by the network side device or the second terminal, and is in the target state during the onDuration period of the next DRX cycle based on the configuration information under the condition that the target condition is met, so that the first terminal and the second terminal are ensured to obtain consistent configuration information, and state switching is accurately realized when WUS signal receiving and transmitting abnormality occurs in SL transmission, so that the UE power saving performance and transmission efficiency are improved.

Optionally, the embodiment of the application provides a scheme that the first terminal reports WUS capability information of the first terminal and/or trend status information of the first terminal to the network side device or the second terminal.

The WUS capability information of the first terminal and the tendency state information of the first terminal may be transmitted separately or together by the first terminal.

Specifically, in the case where WUS capability information of the first terminal and trend state information of the first terminal are transmitted by the first terminal, respectively, the first terminal transmits WUS capability information of the first terminal to the network side device or the second terminal before the first terminal receives configuration information transmitted by the network side device or the second terminal; for example, the first terminal carries WUS capability information of the first terminal in PC5UE capability.

In the case where WUS capability information of the first terminal and trend state information of the first terminal are transmitted by the first terminal, respectively, the first terminal transmits the trend state information of the first terminal to the network side device or the second terminal before the first terminal receives the configuration information transmitted by the network side device or the second terminal; the tendency state information is used for indicating the tendency state of the first terminal when the target condition is met, and the tendency state comprises a dormant state or an awake state. For example, the first terminal carries the tendency state information of the first terminal in the PC5UE information.

Alternatively, the target condition may be used to determine whether or not an abnormality occurs in WUS signal transmission or reception in SL communication, and it may be determined that an abnormality occurs in WUS signal transmission or reception in SL communication when the target condition is satisfied. The target condition may include that the first terminal did not receive the SL WUS;

specifically, the first terminal not receiving the SL WUS may include at least one of:

condition 1, the second terminal does not send SL WUS to the first terminal, and the first terminal does not receive SL WUS;

in practice, the reason why the second terminal does not send the SL WUS to the first terminal includes at least one of the following:

1) The resource location configured as SL WUS belongs outside the SL resource pool, resulting in the second terminal not transmitting the SL WUS;

2) The resource location or time window configured as SL WUS has no valid resources resulting in the second terminal not transmitting SL WUS.

Condition 2, the second terminal has sent the SL WUS to the first terminal, and the first terminal has not received the SL WUS.

In practice, the reason why the second terminal has transmitted the SL WUS to the first terminal and the first terminal has not received the SL WUS includes at least one of:

1) The first terminal does not receive SL WUS based on the receiving and transmitting priority of the first terminal;

2) The first terminal did not successfully decode the SL WUS.

Alternatively, the configuration information may be for all cases of the target condition; in other words, the configuration information may include first indication information for indicating that the first terminal is in a target state during an onDuration of the next DRX cycle in case that the SL WUS is not received.

Alternatively, the configuration information may distinguish between different situations of the target condition; in other words, the configuration information may include the second indication information and the third indication information; the second indication information is used for indicating that a first terminal is in a target state during the onDuration of the next DRX cycle under the condition that the second terminal does not send the SL WUS to the first terminal and the first terminal does not receive the SL WUS; the third indication information is used for indicating that the first terminal is in a target state during the onDuration of the next DRX cycle when the second terminal has transmitted the SL WUS to the first terminal and the first terminal has not received the SL WUS.

Optionally, after receiving the configuration information sent by the network side device or the second terminal, if the target state is a dormant state, the first terminal is in the dormant state during the onDuration of the next DRX cycle if the target condition is met; and under the condition that the target state is the wake-up state, the first terminal performs scheduling monitoring and data receiving during the onDuration period of the next DRX cycle under the condition that the target condition is met.

Fig. 3 is a second flowchart of a terminal power saving method according to an embodiment of the present application, as shown in fig. 3, where the method includes:

step 301, the second terminal sends configuration information to the first terminal; the configuration information is used for indicating that the first terminal is in a target state during the onDuration period of the next DRX cycle under the condition that the first terminal meets a target condition; the target states include: a sleep state or an awake state; the target condition includes at least one of: the second terminal does not transmit the SL WUS; the SL WUS transmitted by the second terminal is not received by the first terminal.

It should be noted that the embodiments of the present application may be applied to a scenario in which WUS signal transmission or reception is abnormal in SL communication. Direct signaling and data transmission is performed between the first terminal and the second terminal based on SL technology. The first terminal, the second terminal includes, but is not limited to, the types of the first terminal 11, the first terminal 12 listed above; the network side devices include, but are not limited to, the types of network side devices 13 listed above.

Optionally, in the case that the service transmission direction is from the second terminal to the first terminal, the first terminal is a service receiving terminal, and the second terminal is a service sending terminal; under the condition that the service transmission direction is from the first terminal to the second terminal, the second terminal is the service receiving terminal, and the first terminal is the service sending terminal. The configuration information is used for normalizing the behavior of the service receiving terminal and enabling the service transmitting terminal to know the behavior of the service receiving terminal, so that the service receiving terminal and the service transmitting terminal can adopt correct consistency processing under the condition of abnormal SL WUS signal transmission or reception.

Specifically, the target state indicated in the configuration information is determined, and only one of the sleep state and the awake state is possible. When the target state is a dormant state, the second terminal does not perform data scheduling and data transmission when the second terminal is in the dormant state; and when the second terminal is in the wake-up state, the second terminal performs data scheduling and data transmission under the condition that the target state is the wake-up state.

Optionally, in the case that the traffic transmission direction is from the second terminal to the first terminal, the manner in which the second terminal obtains the configuration information may include at least one of:

mode 1, the second terminal receives configuration information sent by the network side device.

In practice, the second terminal may send auxiliary information to the network side device; the network side equipment determines configuration information based on the auxiliary information; the network side equipment sends the configuration information to the second terminal; wherein the auxiliary information includes at least one of: service QoS; WUS capability information of the first terminal; WUS capability information of the second terminal; and trend state information of the first terminal, wherein the trend state information is used for indicating trend state of the first terminal when the target condition is met, and the trend state comprises a dormant state or an awake state.

Of course, in other embodiments, the second terminal may not need to send auxiliary information to the network side device, and the network side may directly determine the configuration information and send the configuration information to the second terminal.

For example, if the service QoS requirement is high, the delay is low, or the reliability requirement is high, the receiving terminal can be in the wake-up state as much as possible, and schedule monitoring and data receiving can be performed to ensure the QoS of service receiving; if the receiving terminal is more prone to the power saving requirement, the receiving terminal can be put into a dormant state without scheduling monitoring and data receiving so as to ensure the power saving gain.

Mode 2, the second terminal determines configuration information.

In practice, the second terminal determines the configuration information by itself; alternatively, the second terminal determines the configuration information based on the tendency state information of the first terminal.

Optionally, the embodiment of the application provides a scheme that the second terminal receives WUS capability information of the first terminal and/or trend state information of the first terminal, which are reported by the first terminal.

Specifically, in the case where WUS capability information of the first terminal and trend state information of the first terminal are transmitted by the first terminal, respectively, for WUS capability information of the first terminal, the second terminal receives WUS capability information of the first terminal transmitted by the first terminal before transmitting configuration information to the first terminal; for example, the first terminal carries WUS capability information of the first terminal in PC5 UE capability;

In the case where WUS capability information of the first terminal and trend state information of the first terminal are transmitted by the first terminal, respectively, the trend state information of the first terminal is received before the second terminal transmits the configuration information to the first terminal with respect to the trend state information of the first terminal. For example, the first terminal carries the tendency state information of the first terminal in the PC5 UE information.

Alternatively, the target condition may be used to determine whether or not an abnormality occurs in WUS signal transmission or reception in SL communication, and it may be determined that an abnormality occurs in WUS signal transmission or reception in SL communication when the target condition is satisfied. The target conditions may include, but are not limited to, at least one of:

condition 1, the second terminal does not send SL WUS;

specifically, the reason why the second terminal does not transmit the SL WUS may include at least one of:

2) The resource position or the time window configured as SL WUS has no effective resource, so that the second terminal does not send SL WUS;

3) The second terminal does not compete for the valid resources at the resource location configured as the SL WUS, resulting in the second terminal not transmitting the SL WUS.

Optionally, the second terminal does not transmit the SL WUS, including: the second terminal does not transmit the SL WUS based on the transmission/reception priority of the second terminal, thereby causing the second terminal to not transmit the SL WUS.

Condition 2, SL WUS transmitted by the second terminal is not received by the first terminal.

Specifically, the second terminal has transmitted the SL WUS to the first terminal, and the second terminal does not receive the feedback transmitted by the first terminal, indirectly determines that the first terminal does not receive the SL WUS transmitted by the second terminal, for example, the first terminal does not receive the SL WUS based on the transmission/reception priority of the first terminal, or the first terminal does not successfully decode the SL WUS.

Alternatively, the configuration information may be for all cases of the target condition; in other words, the configuration information may include first indication information for indicating that the first terminal is in a target state during onDuration of the next DRX cycle in a case where the second terminal does not transmit the SL WUS and/or the SL WUS transmitted by the second terminal is not received by the first terminal.

Alternatively, the configuration information may distinguish between different situations of the target condition; in other words, the configuration information may include the second indication information and the third indication information; the second indication information is used for indicating that the first terminal is in a target state during the onDuration of the next DRX cycle under the condition that the second terminal does not send SL WUS; the third indication information is used for indicating that the first terminal is in a target state during the onDuration of the next DRX cycle when the SL WUS transmitted by the second terminal is not received by the first terminal.

Optionally, after receiving the configuration information sent by the network side device or the second terminal, if the target state is a dormant state, the first terminal is in the dormant state during the onDuration of the next DRX cycle if the target condition is met; or when the target state is the wake-up state, the first terminal performs scheduling monitoring and data receiving during the onDuration of the next DRX cycle when the target condition is met.

Fig. 4 is a third flowchart of a terminal power saving method according to an embodiment of the present application, as shown in fig. 4, where the method is performed by cooperation of a first terminal, a second terminal, and a network side device, and the method includes the following steps 401 to 404, where:

step 401, a second terminal receives configuration information sent by network equipment; the configuration information is used for indicating that the first terminal is in a target state during the onDuration period of the next DRX cycle under the condition that the first terminal meets a target condition; the target states include: a sleep state or an awake state; the target conditions include: the first terminal does not receive the SL WUS.

Step 402, the second terminal sends configuration information to the first terminal; the first terminal receives configuration information sent by the second terminal.

Step 403, in the case that the target condition is satisfied and the target state is the sleep state, the second terminal is in the sleep state during the onDuration of the next DRX cycle.

Step 404, when the target condition is satisfied and the target state is the sleep state, the first terminal is in the sleep state during the onDuration of the next DRX cycle.

It should be noted that the execution sequence of step 403 and step 404 is not sequential.

Based on the scheme shown in fig. 4, it can be ensured that the first terminal and the second terminal obtain consistent configuration information, and consistency and synchronization processing is adopted for the condition of abnormal WUS signal receiving and transmitting in SL transmission, so that resources can be saved, and the power saving performance and transmission efficiency of the UE can be improved.

Optionally, in the case that the target state is the awake state and the target condition is met, the second terminal performs data scheduling and data transmission during the onDuration of the next DRX cycle, and the first terminal performs scheduling listening and data receiving during the onDuration of the next DRX cycle, so as to ensure that the first terminal and the second terminal adopt consistent and synchronous processing.

Fig. 5 is a fourth flowchart of a terminal power saving method according to an embodiment of the present application, as shown in fig. 5, where the method is performed by a first terminal and a second terminal in cooperation, and the method includes the following steps 501-505, where:

Step 501, the first terminal sends WUS capability information of the first terminal and/or trend status information of the first terminal to the second terminal; the tendency state information is used for indicating the tendency state of the first terminal when the target condition is met, and the tendency state comprises a dormant state or an awake state.

Step 502, the second terminal determines configuration information based on WUS capability information of the first terminal and/or trend status information of the first terminal.

Alternatively, in the case where the first terminal transmits WUS capability information of the first terminal and trend state information of the first terminal to the second terminal, the second terminal determines the configuration information based on the traffic QoS and trend state information. Or under the condition that the first terminal sends WUS capability information of the first terminal to the second terminal, the second terminal determines configuration information based on a preset target priority state; wherein: the target priority status may include: qoS priority or power saving priority.

Specifically, the QoS priority may be in an awake state corresponding to the target state; the power saving priority may correspond to the target state being a dormant state.

Alternatively, if the first terminal does not report WUS capability information or trend status information in multicast and broadcast, even unicast, the second terminal may perform according to the following scheme:

If the first terminal does not report WUS capacity information and trend state information, the second terminal considers that the first terminal does not have WUS capacity, and configuration information is not required to be determined;

if the first terminal does not report WUS capability information, but reports trend status information, the trend status information may implicitly indicate that the first terminal has WUS capability, and the second terminal considers that the first terminal has WUS capability, and determines configuration information based on the trend status information.

If the first terminal reports WUS capability information but does not report trend state information, the second terminal determines configuration information according to a preset QoS priority principle or a power saving priority principle;

if the individual UE does not report WUS capability information, even if the first terminal of the unicast does not report WUS capability information, the second terminal can normally configure and send configuration information, and for the UE without capability, no WUS signal will be parsed, so its default behavior is to wake up for scheduling and data monitoring during the onDuration of each DRX cycle; the data is still transmitted and received normally, and error leakage does not exist, but the UE without WUS capability cannot save electricity extremely.

Step 503, the second terminal sends configuration information to the first terminal; the first terminal receives configuration information sent by the second terminal.

In step 504, if the target condition is satisfied and the target state is the sleep state, the second terminal is in the sleep state during the onDuration of the next DRX cycle.

In step 505, when the target condition is satisfied and the target state is the sleep state, the first terminal is in the sleep state during the onDuration of the next DRX cycle.

It should be noted that the execution sequence of step 504 and step 505 is not sequential.

Based on the scheme shown in fig. 5, it can be ensured that the first terminal and the second terminal obtain consistent configuration information, and consistency and synchronization processing is adopted for the condition of abnormal WUS signal receiving and transmitting in SL transmission, so that resources can be saved, and the power saving performance and transmission efficiency of the UE can be improved.

Optionally, when the target condition is met and the target state is the awake state, the second terminal performs data scheduling and data transmission during the onDuration of the next DRX cycle, and the first terminal performs scheduling and monitoring and data reception during the onDuration of the next DRX cycle, so as to ensure that the first terminal and the second terminal adopt consistent and synchronous processing.

The embodiments of the present application will be specifically described below from different situations.

The scheme of the embodiment of the application mainly solves the problem of improving the electricity saving performance of the UE when the SL generates abnormal WUS signal transmission or reception. It is assumed that the transmission direction of the target service is from the second terminal to the first terminal, in which case the first terminal is the receiving terminal of the service and the second terminal is the transmitting terminal of the service. The scheme of the embodiment of the application comprises the following steps: the second terminal sends at least one of the following configuration information to the first terminal, or the network side device sends at least one of the following configuration information to the second terminal and the first terminal:

1) In the case that the resource location configured as SL WUS belongs to the SL transmission/reception resource pool, during the onDuration of the next DRX cycle, the first terminal needs to wake up to perform scheduling listening, or may continue to perform a power saving operation, i.e. not perform scheduling detection;

2) Under the condition that the second terminal and the first terminal clearly know that the second terminal cannot send SL WUS, the first terminal needs to wake up to perform scheduling monitoring or can continue to perform power saving operation, namely, scheduling detection is not performed during the onDuration period of the next DRX cycle;

3) Under the condition that the second terminal cannot perform SL WUS transmission due to the transceiving priority processing of the second terminal, the first terminal needs to wake up to perform scheduling monitoring or can continue to perform power saving operation, namely, scheduling detection is not performed during the onDuration period of the next DRX cycle;

4) Under the condition that the first terminal cannot receive SL WUS due to the receiving and transmitting priority processing of the first terminal, the first terminal needs to wake up to perform scheduling monitoring or can continue to perform power saving operation, namely, scheduling detection is not performed during the onDuration period of the next DRX cycle;

5) In the case that the first terminal cannot correctly perform SL WUS reception or decoding due to a link quality problem, the first terminal needs to wake up to perform scheduling listening or may continue to perform a power saving operation, i.e., not perform scheduling detection, during the onDuration of the next DRX cycle.

It should be noted that the above configuration information may be combined, for example, configuration information 1) and 2) require one bit switch indication, configuration information 3), 4) and 5) require another bit switch indication, or configuration information 1) to 5) share one bit switch indication.

Specifically, the configuration information has the effect of normalizing the behavior of the first terminal and making the behavior of the first terminal known to the second terminal, so that a correct consistency process is adopted. The configuration information configured by the second terminal to the first terminal may be from a serving base station of the second terminal, or may be a decision made by the second terminal according to a service condition or a power saving tendency of the first terminal. Optionally, before configuring WUS related configuration information, the second terminal may report WUS capability information of the first terminal to the second terminal, so that the second terminal performs related configuration.

Case one, abnormal WUS processing scheme understood synchronously for both the first terminal and the second terminal.

The first step, the second terminal needs to send configuration information to the first terminal through a PC5 RRC process, or the second terminal and the first terminal respectively obtain the configuration information from the network side equipment, so that the configuration information obtained by the second terminal and the first terminal is consistent, and the consistency and the synchronicity of the first terminal and the second terminal are ensured. In the case that the network side device configures TX and RX respectively, the first terminal wakes up directly or sleeps directly during the onDuration of the next DRX cycle, if it is clear that the second terminal cannot transmit the SL WUS for both the second terminal and the first terminal.

In practice, the configuration information may occupy 1bit;

for example, in the case that both the second terminal and the first terminal know that the SL WUS signal cannot be transmitted, for example, due to a resource pool, there is no effective resource in a position or a time window where the SL WUS signal needs to be monitored, or the WUS resource position/window falls completely outside the SL resource pool, in this case, if the configuration information is configured to be 1, the first terminal is in a sleep state during an onDuration of the next DRX cycle; if the configuration information is configured to be 0, the first terminal is in an awake state during the onDuration of the next DRX cycle;

For another example, in the case that both the second terminal and the first terminal know that the SL WUS signal cannot be transmitted, for example, due to a resource pool, there is no effective resource in a position or a time window where the SL WUS signal needs to be monitored, or the WUS resource position/window falls completely outside the SL resource pool, in this case, if the configuration information is configured to be 0, the first terminal is in a sleep state during an onDuration of the next DRX cycle; if the configuration information is configured to 1, the first terminal is in an awake state during the onDuration of the next DRX cycle.

The second step, after the second terminal and the first terminal both obtain the consistent configuration information, the second terminal and the first terminal respectively process the following when encountering abnormal conditions of wake-up signal receiving and transmitting:

1. if the target state is the dormant state, it means that if the situation that the second terminal and the first terminal synchronously confirm that the SL WUS signal cannot be sent occurs, the second terminal understands that the onDuration of the next DRX cycle of the first terminal is not to wake up and monitor the scheduling, so that the second terminal does not perform any data scheduling and sending during the onDuration of the next DRX cycle, and does not perform resource reservation, if the reserved resources can be considered to be distributed to other transmissions or released, all the data needing to be transmitted need to wait for the onDuration of the next DRX cycle to perform normal scheduling and transmission again.

2. If the target state is the awake state, it means that if the second terminal and the first terminal synchronously confirm that the SL WUS signal cannot be sent, the second terminal understands that the onDuration of the next DRX cycle of the first terminal is to wake up to monitor and schedule, so that the second terminal performs normal data scheduling and sending during the onDuration of the next DRX cycle, and the reserved resources are normally used;

3. for the first terminal, if the target state is the dormant state, it means that if the situation that the second terminal and the first terminal synchronously confirm that the SL WUS cannot be sent occurs, the onDuration of the next DRX cycle of the first terminal will not wake up to monitor the scheduling and data transmission, and the data waits and decides whether to monitor according to the next WUS indication and the onDuration of the next DRX cycle;

4. if the target state is the awake state, it means that if the second terminal and the first terminal synchronously acknowledge that the SL WUS signal cannot be sent, the first terminal needs to wake up to monitor the schedule and transmit data at the onDuration of the next DRX cycle, and if the second terminal has data to send, the schedule and transmit data can be performed during the onDuration.

As can be seen from the above, in this case, since the second terminal and the first terminal are consistent in understanding that the current WUS signal cannot be transmitted, and the acquired configuration information is also consistent, the second terminal and the first terminal may be in a sleep state at the same time, or the second terminal and the first terminal may be in an awake state at the same time, the onDuration behavior of the next DRX cycle is completely synchronized, and thus, waste of resources and extra power consumption are not caused.

And secondly, understanding an abnormal WUS processing scheme which is not necessarily synchronous aiming at the first terminal and the second terminal.

In the first step, the first terminal and the second terminal need to be configured consistently, so that configuration information obtained by the second terminal and the first terminal is ensured to be consistent, and the configuration mode is referred to as a first case. However, in the second case, it is assumed that the first terminal as the service receiving side cannot accurately distinguish the reason why the WUS signal is not received, that is, the first terminal does not know whether the second terminal does not transmit the WUS signal or whether the second terminal transmits the WUS signal but the first terminal does not successfully receive the WUS signal, and for this reason, the configuration information may be configured with two different bits, that is, 0 and 1 of 1 bit are used to configure that the first terminal and the second terminal are in the sleep state or the awake state in the case where the first case occurs, and 0 and 1 of the other bit are used to indicate that the first terminal and the second terminal are in the sleep state or the awake state in the case where the second case occurs, respectively. Of course, the configuration information may use only 1 bit for all cases.

The second step, after the second terminal and the first terminal both obtain the consistent configuration information, the second terminal and the first terminal respectively encounter the abnormal condition of wake-up signal receiving and transmitting as follows:

case 1: the second terminal transmits the WUS signal at the agreed position, and the first terminal does not correctly receive the WUS signal due to link difference or the processing of the transceiving priority of the first terminal:

at this time, the behavior of the second terminal includes: since the second terminal has sent the WUS signal, for example, indicating to wake up or sleep, but the second terminal cannot know the link condition of the first terminal or the transmit-receive conflict and the processing result of the priority, the second terminal cannot accurately determine the state of the first terminal, and the second terminal can only process during the onDuration of the next DRX cycle according to the WUS signal, i.e. if the WUS signal indicates to wake up, the second terminal performs normal scheduling and data sending during the onDuration of the next DRX cycle; if the WUS signal indicates sleep, the second terminal does not schedule and transmit during the onDuration of the next DRX cycle;

the behavior of the first terminal includes: as the end result of the first terminal is that the first terminal does not receive the WUS signal, the first terminal cannot perform the operation of the next DRX cycle according to the WUS signal, and the first terminal can only determine to be in the awake state or the sleep state according to the configuration information: if the configuration information indicates the awake state, the first terminal keeps monitoring and receiving during the onDuration of the next DRX cycle, and if the configuration information indicates the sleep state, the first terminal does not monitor and receive during the onDuration of the next DRX cycle.

When the WUS signal indicates wake-up but the configuration information indicates sleep, the second terminal may determine that the first terminal does not receive the WUS signal based on not receiving feedback sent by the first terminal, and further the second terminal suspends sending data.

Case 2: the second terminal is caused to flush the WUS signal by other higher priority due to the transceiving priority processing of the second terminal, or the second terminal does not compete for the effective resource at the resource location of the WUS, resulting in that the WUS signal is not transmitted:

at this time, the behavior of the second terminal includes: since the second terminal does not send the WUS signal, the second terminal can estimate the behavior of the first terminal according to the configuration information, if the configuration information is that the first terminal is in an awake state if the first terminal does not receive the WUS signal, the second terminal can continue to schedule and transmit during the onDuration of the next DRX cycle, if the configuration information is that the first terminal is in a sleep state if the first terminal does not receive the WUS signal, the second terminal needs to be in a sleep state, i.e. keep silent, during the next DRX cycle onDuration period, and does not send scheduling and transmission;

the behavior of the first terminal includes: since the first terminal does not receive WUS signal as a final result, the first terminal can only decide to be in an awake state or a sleep state in this case according to the configuration information, if the configuration information indicates the awake state, the onDuration at the next DRX cycle keeps listening and receiving, and if the configuration information indicates the sleep state, the onDuration at the next DRX cycle does not listening and receiving;

In this case, the behaviors of the first terminal and the second terminal are also consistent, so that there is no waste of resources and no extra electricity charge caused by useless interception.
