Description

Uplink awakening method and device

Technical Field

The embodiment of the application relates to the field of communication, and more particularly, to a method and a device for uplink wakeup.

Background

With the popularity of the fifth generation (the 5th generation,5G) mobile communication technology in various industries and various geographical areas, the 5G technology is increasingly required to handle more advanced services and more advanced applications. At the same time 5G networks are also becoming denser, using more antennas, more bandwidth and more frequency bands. Most of the energy consumption in 5G systems comes from the radio access network, in particular the active antenna unit (active antenna unit, AAU). The power consumption of a radio access device can be divided into two parts: a dynamic part that consumes energy only when the radio access device performs data transmission/reception; the static part is always consuming energy even when the radio access device is not transmitting/receiving data.

Therefore, how to improve network power saving is a urgent problem to be solved.

Currently, the wireless design of the 5G air interface is based on beam management, and all the transmission and reception of the uplink and downlink channels are based on beams. The base station transmits a narrow beam in a specific direction at a specific point in time, then changes direction again at the next point in time, and so on, can cover all areas, a process called beam scanning. In the 5G air interface, the beam measurement reference signals used include an uplink beam measurement reference signal and a downlink beam measurement reference signal. The downlink beam measurement reference signal may include a beam formed by a synchronization signal block (synchronization signal block, SSB) and a beam formed by a channel-state information reference signal (CSI-RS).

SSB includes a primary synchronization signal (primary synchronization signal, PSS), a secondary synchronization signal (secondarysynchronization signal, SSS), and a physical broadcast channel (physical broadcast channel, PBCH), and a demodulation reference signal (demodulation reference signal, DMRS) demodulated with the PBCH.

For a beam formed by SSB, the transmission timing of SSB is one unit in half frame (i.e., 5 ms), and SSB is transmitted at a certain period. Various SSB formats are defined in the current NR system, and the maximum transmission number of SSB blocks in one SSB transmission half frame (5 ms) is related to frequency. For example, when the frequency of SSB is less than or equal to 3GHz, the maximum transmission number of SSB is 4; when the frequency of the SSB is more than 3GHz and less than or equal to 6GHz, the maximum transmission number of the SSB is 8; when the frequency of SSB is greater than 6GHz, the maximum transmission number of SSB is 34.

Fig. 2 is a schematic diagram of SSB periods according to an embodiment of the present application. When the maximum transmission number of SSBs is 4, the SSB beam scanning schematic diagram is shown in fig. 2, where the abscissa is time, the ordinate is frequency, and in one SSB period, the transmission time of SSBs uses a field frame as a unit to transmit 4 SSBs.

It should be understood that fig. 2 shows only 5ms SSB period for the embodiment of the present application, and that SSB period may also be 10ms, 20ms, 40ms, 80ms, or 160ms.

Currently, in the 5G air interface, when no service data is sent or received by the network device of a cell, the terminal device may be in a sleep/energy-saving state, and when the terminal device needs to send service data to the network device of the cell or requests to access the network device of the cell, the terminal device may send an uplink wake-up signal (uplink wake up signal, UL WUS) to the network device of the cell, so as to wake up the network device of the cell.

There are two ways in which network devices may wake up from a power saving state, and this will be described in detail below in connection with fig. 3.

Fig. 3 is a schematic diagram of a wake-up cell network device according to an embodiment of the present application, where the abscissa in fig. 3 (a) and fig. 3 (b) is time and the ordinate is frequency.

One way to wake up a network device of a cell is as shown in fig. 3 (a), where the period of time for the network device to send SSB is a long period (e.g., 160 ms) when the network device of the cell is in a power saving state. After the network device receives the UL WUS, the network device switches to the awake state, at which time the period in which the network device transmits the SSB is a short period (for example, may be 20 ms). By changing the period of time for the network device to send SSB through UL WUS, the power consumption of the network device can be reduced to some extent.

Another way to wake up the network device of a cell is shown in fig. 3 (b), where the SSB sent by the network device is a simplified SSB when the network device of the cell is in a power saving state. Here, the simplified SSB may be designed for a non-PBCH or PSS/SSS sequence. After the network device receives the UL WUS, the network device switches to the awake state, at which point the SSB sent by the network device is a conventional SSB. The difference between the conventional SSB and the simplified SSB is that sending the conventional SSB consumes more resources and energy. By changing the content in the transmitted SSB through UL WUS, the power consumption of the network device can be reduced to some extent.

The above schemes relate to specific forms of the energy-saving state of the network device, and can reduce the energy consumption of the network device to a certain extent, but in order to further reduce the energy consumption of the network device, the schemes can also be improved on the uplink wake-up signal.

Therefore, the embodiment of the application provides an uplink wake-up method and device, aiming at the improvement of an uplink wake-up signal, the energy consumption of network equipment can be further reduced. The following will describe in detail with reference to fig. 4 to 10.

In order to facilitate understanding of the embodiments of the present application, the following description is made.

It is also possible to indicate only a part of the information to be indicated, while other parts of the information to be indicated are known or agreed in advance. For example, the indication of the specific information may also be achieved by means of a pre-agreed (e.g., protocol-specified) arrangement sequence of the respective information, thereby reducing the indication overhead to some extent. And meanwhile, the universal part of each information can be identified and indicated uniformly, so that the indication cost caused by independently indicating the same information is reduced.

The one or more memories may also be provided separately in part, and integrated in the decoder, processor, or communication device. The type of memory may be any form of storage medium, and this application is not limited in this regard.

In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

Fifth, in this application, "when. . . Time "," at. . . The descriptions of "and" if "and the like in the context of (a) refer to the fact that the device will perform the corresponding process under some objective condition, and are not limited in time, nor do they require that the device must have a judgment in terms of its implementation act, nor are they meant that other limitations may not exist.

Fig. 4 is a flowchart of a method 400 for uplink wakeup according to an embodiment of the present application.

The method 400 of uplink wakeup illustrated in fig. 4 is an example of a corresponding method using the network device and the first terminal device as the execution bodies of the interaction entity, but the application is not limited to the execution bodies of the interaction. For example, the network device in fig. 4 may also be a chip, a system-on-a-chip or a processor supporting the network device to implement the corresponding method, or may be a logic module or software capable of implementing all or part of the functions of the network device. The first terminal device in fig. 4 may also be a chip, a chip system or a processor supporting the first terminal device to implement the corresponding method, or may also be a logic module or software capable of implementing all or part of the functions of the first terminal device.

As shown in fig. 4, the method 400 of uplink wakeup includes the following steps.

S410, the network device sends first configuration information to the first terminal device, wherein the first configuration information comprises a trigger condition.

It should be understood that the trigger condition is used to indicate whether the first terminal device may send the first uplink wake-up signal to the network device of the current cell.

As a possible implementation, the network device sends the first configuration information to the terminal device on a first message, where the first information is RRC signaling, or a system information broadcast message.

For example, the first terminal device may receive the first configuration information from the network device in an RRC connection release (RRC release) signaling or a system broadcast message, so that the first terminal device uses the first configuration information when in an inactive state (inactive).

For example, for a connected first terminal device, first configuration information from the network device may be received in RRC reconfiguration (RRC reconfiguration) signaling.

For example, for a first terminal device in idle state (idle), the first configuration information from the network device may be received in a system broadcast message. For example, the system broadcast message may be a system information block 1 (system information block 1, SIB 1) or other system information block (other SI).

And S420, when the triggering condition is met, the first terminal equipment sends a first uplink wake-up signal to the network equipment, and the network equipment receives the first uplink wake-up signal from the first terminal equipment.

As a possible implementation, the trigger condition is a decision condition for at least one of the following parameters: the first service type is the type of the first service of the first terminal equipment; the first equipment type is the type of the first terminal equipment; the first cell identifier is the cell identifier of the last service cell of the first terminal equipment.

As a possible implementation, the triggering condition may also be a decision condition for a synchronization margin (synchronization margin) or a synchronization accuracy deviation (synchronization accuracy deviation) or a maximum synchronization accuracy (maximum synchronization accuracy).

And S430, the network equipment sends a first synchronization signal block and/or a first system information block according to the first uplink wake-up signal.

As a possible implementation, the broadcast period of the first synchronization signal block is a short period, for example 20 milliseconds.

Specifically, before the network device receives the first uplink wake-up signal, the network device broadcasts a second synchronization signal block, where a broadcast period of the second synchronization signal block is a long period, for example, 160 milliseconds. When the network device receives the first uplink wake-up signal, the network device wakes up, and the network device sends a first synchronization signal block, wherein the broadcasting period of the first synchronization signal block is shorter than that of the second synchronization signal block.

As a possible implementation, the first synchronization signal block is an un-simplified synchronization signal block.

Specifically, before the network device receives the first uplink wake-up signal, the network device sends a third synchronization signal block, where the third synchronization signal block is a simplified synchronization signal block. For example, the simplified synchronization signal block may have no PBCH or PSS/SSS with different sequence designs.

As a possible implementation, the network device does not broadcast the first system information block before the network device receives the first uplink wake-up signal.

Specifically, the first system information block (e.g., SIB 1) defines scheduling information of other system information blocks, and information of initial access network of the terminal device, such as random access resources, etc. After the network device receives the first uplink wake-up signal, the network device wakes up and the network device transmits a first system information block (e.g., SIB 1). The specific form of the first system information block is not limited in this embodiment, and may be SIB1 or other SIBs.

As a possible implementation, the broadcast period of the first system information block is a short period, e.g. 20 ms.

Specifically, the network device broadcasts a long period of system information blocks, e.g., 160 milliseconds, before the network device receives the first uplink wake-up signal. When the network device receives the first uplink wake-up signal, the network device wakes up, and the network device transmits a first system information block, wherein the broadcasting period of the first system information block is shorter than that of the second system information block.

In the above technical solution, the network device configures, through the first configuration information, a trigger condition for the terminal device to send an uplink wake-up signal, that is, the network device only allows the relevant parameters of the terminal device to send the uplink wake-up signal when the trigger condition is satisfied, so as to wake up the network device in the current cell, thereby further reducing the energy consumption of the network device.

Fig. 5 is a flowchart of another method 500 for uplink wakeup according to an embodiment of the present application. As shown in fig. 5, specific steps of the method 500 for uplink wakeup are as follows.

The method 400 of uplink wakeup is described in further detail below in conjunction with fig. 5. The execution body of the interactive illustration in fig. 5 is similar to that in fig. 4, and the detailed description of fig. 4 is referred to for the relevant description.

S510, the first terminal device sends third indication information to the network device, wherein the third indication information is used for indicating capability information supported by the terminal device.

As one possible implementation, the capability information includes at least one of the following information: the terminal equipment supports the capability information of sending a first uplink wake-up signal; the terminal equipment supports the capability information of sending a first uplink wake-up signal in some cells; the terminal equipment supports the capability information that the terminal equipment can only send a first uplink wake-up signal to the last service cell before the cell reselection occurs according to the cell identifier; the terminal equipment supports the capability information of sending a first uplink wake-up signal to the first service type.

It should be understood that the capability information limiting the cell identities is the capability that the terminal device may correspond to the cell identity of the current cell network device limiting certain cell identities without sending an uplink wake-up signal to the current cell network device.

Optionally, before S510, the network device may send terminal device capability report request information to the terminal device.

S520, the network device sends first configuration information to the terminal device, wherein the first configuration information comprises a trigger condition.

It should be understood that S520 is similar to S410, and is not described here in detail for brevity.

S530, the first terminal device judges whether the triggering condition is met.

As a possible implementation manner, the first terminal device obtains a first service type, and determines that a trigger condition is met when the first service type belongs to a first set, where the first set includes at least one service type that meets the trigger condition, and the trigger condition includes the first set. Or when the first service type does not belong to the second set, determining that the triggering condition is met, wherein the second set comprises at least one service type which does not meet the triggering condition, and the triggering condition comprises the second set.

For example, the at least one traffic type may be at least one of the following types: data radio bearer (data radio bearer, DRB), logical channel, network slice access layer packet (network slice access group, NSAG) or signaling of signaling radio bearer (signaling radio bearer, SRB) 2. Wherein the uplink signaling of SRB2 may be uplink positioning signaling or other uplink non-access stratum (NAS) signaling.

Specifically, if the traffic type in the first set of trigger conditions includes an uplink DRB, the first set may include an identity of the DRB. If the traffic type in the first set of trigger conditions includes NSAG, the first set may include an identification of NSAG. Optionally, the first set may include an identification of NSAG and a tracking area code (tracking area code, TAC).

It should be appreciated that the representation of the specific service types in the second set is similar to that of the first set, and will not be described in detail herein. The difference between the first set and the second set is that if the first service type of the first terminal device matches the service type in the first set, the sending of the first uplink wake-up signal can be triggered; if the first service type matches the service type in the second set, the sending of the first uplink wake-up signal cannot be triggered.

As a possible implementation manner, the first terminal device obtains the first device type, and determines that the trigger condition is met when the first device type belongs to a third set, where the third set includes at least one device type that meets the trigger condition. Alternatively, when the first device type does not belong to a fourth set, determining that the trigger condition is satisfied, the fourth set including at least one device type that does not satisfy the trigger condition.

For example, the at least one device type may be at least one of the following types: reduced capability (reduced capability, redcap) terminal devices, coverage enhanced supported terminal devices, terminal devices with certain specific access identities (access identities), terminal devices supporting small data transmissions (small data transmission, SDT), cellular internet of things (cellular internet of things, CIOT) terminal devices, narrow bandwidth internet of things (narrow band internet of Things, NB-IoT) terminal devices, passive internet of things (passive internet of things, passive IoT) terminal devices, and the like. The Redcap terminal device may be further divided into a Redcap terminal device using a 1RX antenna and a Redcap terminal device using a 2RX antenna. The terminal device supporting coverage enhancement may be a terminal device supporting message 3repetition (msg 3 repetition). The terminal device with some specific access identities may be decided by the terminal device itself.

Specifically, if the device type in the third set of trigger conditions is at least one of the above types, the third set may include identification information of the above device types. The device types in the fourth set perform similarly to the third set.

As a possible implementation manner, when the trigger condition is for the first cell identifier, the trigger condition is used for indicating whether the first cell indicated by the first cell identifier triggers the sending of the first uplink wake-up signal, and the first terminal device obtains the first cell identifier, where the first cell identifier is the cell identifier of the last serving cell where the first terminal device resides before cell reselection.

Specifically, when the triggering condition indicates that the first cell identifier is not limited to trigger the sending of the first uplink wake-up signal, the first uplink wake-up signal is sent.

For example, the triggering condition indicates that the transmission of the first uplink wake-up signal can only be triggered on the first cell indicated by the first cell identity by field 1. For another example, the triggering condition indicates, through a field 0, that the triggering of the sending of the first uplink wake-up signal on the first cell indicated by the first cell identifier is not limited, that is, the terminal device may trigger the sending of the first uplink wake-up signal in the current cell.

As another example, the trigger condition is indicated by a broadcast field. When broadcasting the field, the terminal device can only trigger the transmission of the first uplink wake-up signal on the first cell indicated by the first cell identification. When the field is not broadcast, the terminal device may trigger transmission of the first uplink wake-up signal in the current cell.

The specific indication mode of the triggering condition is not limited in the application.

It should be understood that, after receiving the RRC release message sent by the network device of the last serving cell where the first terminal device resides, the first terminal device stores the cell identifier of the serving cell, so as to obtain the first cell identifier corresponding to the last serving cell.

As a possible implementation, when the trigger condition is for a synchronization margin or a synchronization accuracy deviation or a maximum synchronization accuracy, the terminal device detects whether the downlink synchronization performance exceeds the synchronization margin or whether the maximum synchronization accuracy is exceeded or whether the downlink synchronization performance satisfies the synchronization accuracy deviation.

For example, in the case where the terminal device detects that the downlink synchronization performance exceeds the synchronization margin or detects that the downlink synchronization performance satisfies the synchronization accuracy deviation, the trigger condition is satisfied. Or under the condition that the terminal equipment detects that the downlink synchronization performance does not exceed the synchronization allowance or the terminal equipment detects that the downlink synchronization performance does not meet the synchronization precision deviation, the triggering condition is met.

For example, in the case where the terminal device detects that the downlink synchronization performance does not exceed the synchronization margin or detects that the downlink synchronization performance does not satisfy the synchronization accuracy deviation, the trigger condition is not satisfied. Or under the condition that the terminal equipment detects that the downlink synchronization performance exceeds the synchronization allowance or the terminal equipment detects that the downlink synchronization performance meets the synchronization precision deviation, the triggering condition is not met.

For example, in the case that the terminal device detects that the downlink synchronization performance does not exceed the maximum synchronization accuracy, the trigger condition is satisfied. And when the terminal equipment detects that the downlink synchronization performance exceeds the maximum synchronization precision, the triggering condition is not satisfied.

S540, when the triggering condition is met, the first terminal device sends a first uplink wake-up signal to the network device, and the network device receives the first uplink wake-up signal from the first terminal device.

It should be understood that S540 is similar to S420, and is not described here in detail for brevity.

And S550, the network equipment sends a first synchronization signal block and/or a first system information block according to the first uplink wake-up signal.

It should be understood that S550 and S430 are similar, and are not described here in detail for brevity.

In the embodiment of the application, the network device can autonomously determine the condition for triggering the terminal device to send the uplink wake-up signal, so that the terminal device is prevented from unconditionally sending the uplink wake-up signal to the network device, and the power consumption of the network device is further reduced. For example, the network device may determine, through the configuration information, a service type and a device type that trigger the terminal device to send an uplink wake-up signal. For another example, if the network device of the current cell does not release any terminal device, the terminal device moving to the current cell can be limited to send the uplink wake-up signal by limiting the cell identifier of the serving cell where the terminal device resides before cell reselection, and the network device of the current cell does not need to monitor any uplink wake-up signal, so that the opportunity of further reducing power consumption of the network device can be increased.

Fig. 6 is a flowchart of another method 600 for uplink wakeup according to an embodiment of the present application. As shown in fig. 6, the method 600 of uplink wakeup includes the following steps.

It should be understood that the execution body shown in the interactive schematic in fig. 6 is similar to that in fig. 4, and the related description may refer to the detailed description in fig. 4.

And S610, the network equipment sends a fourth indication information number to the first terminal equipment, and the first terminal equipment receives the fourth indication information number from the network equipment, wherein the fourth indication information number is used for indicating one or more first resources and partition information corresponding to the one or more first resources.

It should be understood that the first resource may be an air interface resource, for example, any one of a time domain resource, a frequency domain resource, and a code domain resource, and the embodiment of the present application does not limit the type of the first resource.

When the first resources are plural, the division information of the plural first resources can also be understood as division information for dividing the second resources allocated to the first terminal device into the plural first resources. The following description mainly uses a plurality of first resources as examples.

S620, the first terminal equipment determines target resources from one or more first resources according to the partition information of the first resources.

As a possible implementation manner, the partition information of the first resources may be the number of the first resources, the number of the first resources may be related to the temporary identifier of the terminal device, or the number of the first resources may be related to the service type of the terminal device.

It should be appreciated that the number of first resources and the traffic associated with the traffic type may have the same traffic prioritization in different terminal devices.

The number of first resources may be related to the service type of the terminal device, and it may be further understood that one or more first resources are divided according to the service type.

The number of first resources may be related to the temporary identity of the terminal device, and it may be further understood that one or more first resources are divided according to the temporary identity of the terminal device.

For example, the traffic type may be any of NSAG, 5G quality of service identity (5G quality of service identifier,5QI) or quality of service flow (quality of service flow, qoS flow).

For example, the device type is similar to that in S530, and for brevity, description thereof will be omitted.

As a possible implementation manner, the partition information of the first resources may also be a first mapping relationship between a plurality of first resources and the device type set.

As a possible implementation manner, the partition information of the first resources may also be a second mapping relationship between one or more first resources and the service type priority.

The traffic type may be, for example, a logical channel or a radio bearer.

As a possible implementation manner, the target resource is a time domain resource for transmitting the third uplink wake-up signal.

As a possible implementation manner, the target resource is a frequency domain resource for transmitting a third uplink wake-up signal. For example, the frequency domain resources are mapped to different initial bandwidth parts (BWP).

As a possible implementation manner, the target resource is a code domain resource for transmitting a third uplink wake-up signal. For example, the code domain resources are mapped to different transmission sequences.

It should be appreciated that the target resource may be any combination of time-frequency domain resources.

And S630, the first terminal equipment sends a third uplink wake-up signal to the network equipment based on the determined target resource.

And S640, the network equipment determines whether to send a fourth synchronous signal and/or a second system information block according to the third uplink wake-up signal according to the wake-up indication information corresponding to the target resource.

As a possible implementation manner, the network device determines whether to send the fourth synchronization signal and/or the second system information block according to the third uplink wake-up signal according to the second service type corresponding to the third uplink wake-up signal indicated by the wake-up indication information.

Specifically, when the second traffic type is any one of the traffic types illustrated in S620, it is determined that the fourth synchronization signal is transmitted according to the third uplink wakeup signal. Wherein the correlation property of the fourth synchronization signal block is similar to that of the first synchronization signal block, and the correlation property of the second system information block is similar to that of the first system information block, reference is made to S430. The embodiment of the application does not limit the specific form of the second system information block, and may be SIB1 or other SIBs.

As a possible implementation manner, the network device determines, according to the second device type of the first terminal device indicated by the wake-up indication information, whether to send the fourth synchronization signal according to the third uplink wake-up signal.

Specifically, when the second device type is any one of the service types illustrated in S530, it is determined that the fourth synchronization signal and/or the second system information block is transmitted according to the third uplink wakeup signal.

As a possible implementation manner, the network device receives the second uplink wake-up signal from the at least one second terminal device on the target resource, and the network device determines whether to send the fourth synchronization signal and/or the second system information block according to the third uplink wake-up signal according to the number of the third uplink wake-up signal and the second uplink wake-up signal carried on the target resource indicated by the wake-up indication information.

It should be understood that each second terminal device corresponds to one second uplink wake-up signal, and thus, the number of terminal devices transmitting the uplink wake-up signal can be obtained through the number of the third uplink wake-up signal and the second uplink wake-up signal carried on the target resource.

Specifically, when the second number is greater than or equal to the threshold number of terminal devices, determining to send a fourth synchronization signal block, where the second number is the number of corresponding second terminal devices and first terminal devices on the target resource.

In the above technical solution, according to the received wake-up indication of the target resource, the network device may distinguish the number of terminal devices sending the uplink wake-up signal or the service type corresponding to the uplink wake-up signal or the device type of the terminal device, so as to determine the sending policy of the corresponding synchronization signal block. Therefore, the network equipment does not need to be awakened unconditionally according to the uplink awakening signal, and the energy consumption of the network equipment can be further reduced. Or, through different target resource wake-up instructions, uplink wake-up signal interference among the terminal devices can be reduced, so that the terminal devices can more accurately detect uplink signals and determine a sending strategy of the synchronous signal block.

It should be appreciated that the method 400 of uplink wakeup may be applied in conjunction with the method 600 of uplink wakeup, or the method 500 of uplink wakeup may be applied in conjunction with the method 600 of uplink wakeup. The above-described bonding application will be described in detail with reference to fig. 7.

The above scheme will be described in further detail with reference to fig. 7.

It should be understood that the execution bodies shown in fig. 7 are similar to those shown in fig. 4, and the detailed description of fig. 4 may be referred to for the relevant description.

Fig. 7 is a flowchart of another method 700 for uplink wakeup according to an embodiment of the present application. As shown in fig. 7, the method 700 of uplink wakeup includes the following steps.

S710, the network device sends first configuration information to the first terminal device, where the first terminal device receives the first configuration information from the network device, where the first configuration information includes a trigger condition and first indication information, and the first indication information is used to indicate one or more first resources and partition information of the one or more first resources.

It should be understood that the detailed explanation of the trigger condition may refer to S410, the first indication information corresponds to the fourth indication information in S610, and the related explanation may refer to S610. The following description mainly uses a plurality of first resources as examples.

It should also be understood that when the partition information is the number of the plurality of first resources, the first indication information is used to indicate the number of the plurality of first resources; when the partition information is a first mapping relationship between the plurality of first resources and the device type set, the first indication information is used to indicate the first mapping relationship between the plurality of first resources and the device type set, and the first indication information may be also referred to as second indication information. When the partition information is a second mapping relationship between the plurality of first resources and the service type, the first indication information is used to indicate the second mapping relationship between the plurality of first resources and the device type set, and the first indication information may be also referred to as eighth indication information.

Optionally, before S710, the first terminal device sends seventh indication information to the network device, where the seventh indication information is used to indicate capability information supported by the terminal device.

As one possible implementation, the capability information includes at least one of the following information: the terminal equipment supports the capability information of sending a first uplink wake-up signal; the terminal equipment supports the capability information of determining target resources according to the partition information of a plurality of first resources; the terminal device supports capability information that the terminal device can only send the first uplink wake-up signal in the cell indicated by the cell identification of the last serving cell.

S720, the first terminal equipment determines target resources from one or more first resources according to the partition information of the first resources.

As a possible implementation manner, the partition information of the first resources is the number of the first resources, when the number of the first resources is related to the service type of the terminal device, the first terminal device obtains the first service type, and determines the target resources from one or more first resources according to the number of the first resources and the identification of the first service type.

Specifically, a target identifier is obtained according to the number of the first resources and the identifier of the first service type, and the first resource corresponding to the target identifier is determined to be the target resource.

It should be appreciated that the target identification may be an index of the target resource.

For example, the target identifier may be obtained as shown in formula (1).

subgroup ID＝(service ID)mod(subgroup number for service) (1)

Where subgrouping ID represents the target identifier, service ID represents the identity of the first service type, and subgroup number for service represents the number of first resources.

For example, when the first traffic type is NSAG, the service ID represents an identity of the NSAG and subgroup number for service represents a number of first resources for the NSAG. The first traffic type may also be 5QI or QoS flow.

Because the identities of the NSAG, the 5QI and the QoS flows with the same priority are the same in different terminal devices, different terminal devices can send uplink wake-up signals triggered by the service with the same priority on the same target resource through the scheme, which is helpful for network devices to send the first synchronization signal blocks according to corresponding strategies.

As a possible implementation manner, the partition information of the first resources is the number of the first resources, and when the number of the first resources is related to the temporary identifier of the terminal device, the first terminal device obtains the first temporary identifier, and determines the target resource from the plurality of first resources according to the number of the first resources and the first temporary identifier.

Specifically, a target identifier is obtained according to the number of the first resources and the first temporary identifier, and the first resource corresponding to the target identifier is determined to be the target resource.

For example, the target identifier may be obtained as shown in formula (2).

subgroup ID＝(UE ID)mod(subgroup number for UE ID) (2)

Where subgrouping ID represents a target identity, UE ID represents a first temporary identity of a terminal device, subgroupnumber for UE ID represents a number of first resources for the terminal device temporary identity.

As a possible implementation manner, when the partition information of the first resources is a first mapping relationship between a plurality of first resources and a device type set, the first terminal device obtains a first device type, and determines a target resource from the plurality of first resources according to the first mapping relationship and the first device type.

As a possible implementation manner, the partition information of the first resources is a second mapping relationship between a plurality of first resources and service type priorities. The first terminal equipment acquires a first service type, and determines a target resource from one or more first resources according to the first service type and the second mapping relation.

For example, the first traffic type associated with the second mapping relationship may be a logical channel or a radio bearer.

For example, when the first service type is a radio bearer or a logical channel, the first terminal device obtains the first service type, and determines a target resource from one or more first resources according to the first service type and the second mapping relationship.

It should be understood that, due to the priority of the radio bearer or the logic channel, the terminal device may select different target resources to send the uplink wake-up signal according to the second mapping relation related to the service type, so as to implement resource differentiation based on service priority.

As a possible implementation, when the first resource is a time domain resource, the first resource is represented as a time domain symbol, or a subframe or a slot. For example, at least two first resources may be represented as different time domains (e.g., different subframes, slots).

As a possible implementation, when the first resource is a frequency domain resource, the first resource is denoted as an initial BWP. For example, at least two first resources may be represented as different BWP.

As one possible implementation, when the first resources are code domain resources, the first resources are denoted as uplink transmission sequences.

S730, the first terminal device judges whether a triggering condition is satisfied.

It should be understood that S730 is similar to S530, and for brevity, reference is made to S530 for details.

And S740, when the triggering condition is met, the first terminal equipment sends a first uplink wake-up signal to the network equipment on the target resource.

And S750, the network equipment determines whether to send a first synchronization signal and/or a first system information block according to the first uplink wake-up signal according to the wake-up indication information corresponding to the target resource.

It should be understood that, because the first terminal device sends the first uplink wake-up signal on the premise that the trigger condition is satisfied, when the wake-up indication information indicates that the service type of the terminal device is a first service type or the first service type does not belong to a second set, it is determined that the first synchronization signal is sent according to the first uplink wake-up signal. Or when the equipment type indicated by the wake-up indication information is the equipment type of the terminal equipment, the first equipment type belongs to the third set or the first equipment type does not belong to the fourth set, and the first synchronization signal is determined to be sent according to the first uplink wake-up signal. The relevant explanation regarding the first set, the second set, the third set, and the fourth set may refer to S530.

When the number of uplink wake-up signals sent on the target resource is indicated by the wake-up indication information, the number of the uplink wake-up signals is equal to the number of the terminal devices requesting to wake-up the network device because the uplink wake-up signals are in one-to-one correspondence with the terminal devices. At this time, the network device determines whether to transmit the first synchronization signal and/or the first system information block according to the first uplink wake-up signal according to the number of the first uplink wake-up signal and the second uplink wake-up signal indicated by the wake-up indication information. The second uplink wake-up signal is from another terminal device, e.g. the second terminal device.

Specifically, when the first number is greater than or equal to the threshold number of terminal devices, determining to send the first synchronization signal block and/or the first system information block, wherein the first number is the number of the corresponding second terminal devices and first terminal devices on the target resource.

In the above technical solution, the network device may identify the number, service type or device type of the terminal device sending the uplink wake-up signal according to the wake-up indication information corresponding to the target resource, so as to determine a corresponding wake-up policy, and further reduce power consumption of the network device. In addition, the first wake-up signal received by the network device already meets the trigger condition, so that the power consumption of the network device can be further reduced.

Fig. 8 is a flowchart of another method 800 for uplink wakeup according to an embodiment of the present application. As shown in fig. 8, the specific steps of the method 800 for uplink wakeup are as follows.

It should be understood that the execution bodies shown in fig. 8 are similar to those shown in fig. 4, and the detailed description of fig. 4 may be referred to for the relevant description.

Optionally, S810, the network device sends a sixth indication information number to the terminal device, where the sixth indication information number is used to indicate that the network device supports receiving the fourth uplink wake-up signal.

As a possible implementation manner, the network device sends the sixth indication information number to the terminal device through the system broadcast information.

As a possible implementation, when the SSB sent by the sleep state of the network device is simplified SSB (light SSB), the sixth indication information number is sent through the synchronization sequence indicated by the SSB.

S820, the network device sends fifth instruction information to the terminal device, where the fifth instruction information is used to instruct the terminal device to send the fourth uplink wake-up signal multiple times.

As a possible implementation manner, the fifth indication information number includes a transmission period of the fourth uplink wake-up signal.

It will be appreciated that the transmission period is used to indicate the duration of the interval between the first transmission of the fourth upstream wakeup signal and the retransmission of the fourth upstream wakeup signal.

As a possible implementation manner, the fifth indication information number further includes a total duration of transmitting the fourth uplink wake-up signal multiple times, or a threshold of a number of times of transmitting the fourth uplink wake-up signal.

It should be appreciated that the total duration is used to indicate the total duration that may be used to transmit the fourth uplink wakeup signal since the first transmission of the fourth uplink wakeup signal.

It should be understood that the transmission number threshold represents the maximum transmission number of the fourth uplink wake-up signal.

And S830, the terminal equipment sends a fourth uplink wake-up signal to the network equipment again according to the fifth indication information number.

As a possible implementation manner, if the indication information that the network device is awakened is not detected in the transmission period after the fourth uplink wake-up signal is first transmitted, the fourth uplink wake-up signal is transmitted again.

As a possible implementation manner, if the first time period exceeds the total transmission time period and no indication information that the network device is awakened is detected, starting random access or performing cell reselection, where the first time period is a time period when the fourth uplink awakening signal is initially transmitted to the current time.

As a possible implementation manner, if the number of transmissions exceeds the threshold number of transmissions, and no indication information that the network device is awakened is detected, the terminal device starts random access or performs cell reselection.

It should be appreciated that the indication that the network device is awake may be a short period SSB, or an un-simplified SSB.

As a possible implementation manner, if the number of times of sending the fourth uplink wake-up signal reaches the threshold of the number of times of sending, no indication information that the network device is woken up is detected, then random access indication information is sent or cell reselection is performed.

And S840, the network equipment sends a fifth synchronous signal block and/or a third system information block according to the fourth uplink wake-up signal.

As a possible implementation manner, after receiving the third uplink wakeup, the network device sends the fifth synchronization signal block and/or the third system information block with the first time offset.

It should be understood that the detailed explanation of the fifth synchronization signal block may refer to the first synchronization signal block in S430, and the detailed explanation of the third system information block may refer to the first system information block in S430. The embodiment of the application does not limit the specific form of the third system information block, and may be SIB1 or other SIBs.

In the above technical solution, the uplink wake-up signal sending mode is defined, and the terminal device does not need to continuously send the uplink wake-up signal, and meanwhile, blind detection of the uplink wake-up signal by the network device is avoided, thereby further reducing power consumption of the terminal device and the network device.

The method of uplink wakeup may be used alone, or may be further applied in combination with the method of uplink wakeup 800. For example, the method 800 for uplink wakeup may be applied in combination with the method 400 for uplink wakeup, the method 500 for uplink wakeup, the method 600 for uplink wakeup, and the method 700 for uplink wakeup, respectively.

It will be appreciated that for a connected terminal device, it may access multiple serving cells simultaneously. The cell providing the mobility information of the non-access stratum is a primary cell (PCell), and the other serving cells are secondary cells (scells). The above technical solution may be applicable to scells only, as well as PCell.
