This disclosure relates to but is not limited to the field of communication technology, and in particular, to a monitoring method, a monitoring apparatus, a communication device and a storage medium.
Currently, when UE (User Equipment) in a non-connected state monitors the paging message, it usually performs the monitoring in the DRX (Discontinuous Reception) cycle. Generally, when the UE detects a wakeup signal, it means that the UE needs to monitor the PDCCH (Physical Downlink Control Channel). If no wakeup signal is received, the PDCCH monitoring is skipped. Since no matter what kind of wakeup signal is concerned, the terminal needs to detect the wakeup signal, it is desired to introduce a separate transceiver (ultra-low power wake-up receiver) to receive the wakeup signal. However, after introducing the separate transceiver for the LIE, there is no solution yet for the working state of the terminal.

In order to facilitate understanding by those skilled in the art, the embodiments of this disclosure enumerate multiple implementations to clearly describe the technical solutions according to some embodiments of this disclosure. Those skilled in the art can understand that the multiple embodiments provided in this disclosure can be implemented alone or in combination with the methods according to other embodiments of this disclosure. They can also be implemented alone or in combination with some methods in related art. Embodiments of this disclosure do not limit this.
In order to better understand the technical solution described in any embodiment of this disclosure, a partial description of the power saving signal in related art is given as follows.
As an example, in the power saving project of R16, a power saving signal is introduced for UE in the connected sate. The power saving signal may be a wakeup signal or a DCI (downlink control information) for power saving (DCP). For example, if the UE detects the wakeup signal, it is determined that the UE needs to monitor (or referred to as listen to) the PDCCH; if the UE detects no wakeup signal, the PDCCH monitoring is skipped.
As another example, in the power saving project of R17, a power saving signal is introduced for UE in the idle state. The power saving signal may be a PEI (paging advance indication). Here, the PEI can be configured before the PO (paging occasion). For example, if the UE detects the power saving signal, it needs to monitor the paging DCI, if the UE detects no power saving signal, it skips monitoring the paging DCI.
As yet another example, enhancements are made to connected UEs in R17, and a PDCCH skipping mechanism is introduced. For example, if the UE detects a DCI carrying information indicating the PDCCH skipping mechanism, it determines to skip monitoring for a preset duration or perform switching of search space group.
As shown in
In step S21, a first transceiver of the UE monitors a wakeup signal, where the wakeup signal is used to wake up a second transceiver of the UE.
In some embodiments, the UE may be various mobile terminals or fixed terminals. For example, the UE may be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a game control platform, a multimedia device, or the like,
This step S21 may be implemented as that the UE in the RRC (Radio Resource Control) non-connected state monitors the wakeup signal by using the first transceiver. Here, the RRC non-connected state includes: RRC idle state and/or RRC inactive state. Here, the RRC non-connected state may also be a newly defined RRC non-connected state. For example. the newly defined RRC non-connected state is the RRC ultra-unconnected state, where the RRC ultra-unconnected state includes: RRC ultra-idle state (RRC ultra-IDLE) and/or RRC ultra-inactive state (RRC ultra-INACTIVE).
This step S21 may be implemented as that the first transceiver of the UE monitors the wakeup signal sent by a network device. Here, the network device may be an access network device or a core network device, where the access network device may be, but is not limited to, a base station; and the core network device may be, but is not limited to, various network functions or entities that implement network functions. Here, the base station may be, but is not limited to, at least one of the following: a 3G base station, a 4G base station, a 5G base station and other evolved base stations. If the wakeup signal is sent by the core network device, the core network device sends the wakeup signal to the base station, and the base station forwards the wakeup signal to the UE.
Here, the awakened second transceiver is configured to monitor a paging message. Alternatively, the awakened second transceiver can also be configured to perform any implementable operation including, for example, monitoring system message, performing cell selection or reselection, and/or performing cell measurement, and the like.
Here, a power consumption of the first transceiver is less than a power consumption of the second transceiver. When referring to that the power consumption of the first transceiver is less than the power consumption of the second transceiver, it may be as follows: a power consumed by the first transceiver for receiving and/or sending information is less than a power consumed by the second transceiver for receiving and/or sending information. For example, less power is consumed by the first transceiver decoding each signal than the second transceiver decoding the same signal.
In some embodiments, the UE includes the first transceiver and the second transceiver, where the power consumption of the first transceiver is less than that of the second transceiver. Here, the structure of the first transceiver is very simpler compared to the structure of the second transceiver. The second transceiver may be the main transceiver of the UE, while the first transceiver is an independent transceiver (ultra-low power wake-up receiver) introduced for the UE.
In some embodiments, the first transceiver has the functions of receiving and sending, and the second transceiver has the functions of receiving and sending.
In some embodiments, the first transceiver may also be: a first receiver; and/or the second transceiver may be: a second receiver. Here, the first receiver has the function of receiving, and/or the second receiver has the function of receiving.
In some other embodiments, the first transceiver is a secondary transceiver, and the second transceiver is a primary transceiver. Here, the secondary transceiver is configured to assist the primary transceiver in receiving and/or sending information.
Here, the wakeup signal is used to trigger exiting a working mode of monitoring the wakeup signal based on the first transceiver.
In some embodiments, the wakeup signal may be any power saving signal. For example, the wakeup signal may be the PEI signal or the DCP signal mentioned above: or the wakeup signal may be a signal with fewer bits than the PEI signal or the DCP signal, as long as the wakeup signal can be used to wake up the second transceiver.
In some embodiments, the wakeup signal may be a signal less than or equal to a first power. For example, the wakeup signal may be a low-power wakeup signal.
For example, the wakeup signal may be a preset bit signal such as “00”, “001”, “00111” or the like. The wakeup signal may be used to wake up the second transceiver to monitor the paging message.
In an embodiment of this disclosure, the UE may monitor the wakeup signal based on the first transceiver of the UE, where the wakeup signal is used to wake up the second transceiver of the UE, In this way, after introducing the first transceiver with relatively low power consumption for the UE, the first transceiver with relatively low power consumption can monitor the wakeup signal before waking up the second transceiver with relatively high power consumption, without having the second transceiver with relatively high power consumption to monitor the wakeup signal, thereby saving the power consumption and battery life of the UE.
In some embodiments of this disclosure, the wakeup signal is used to wake up the second transceivers of at least some UEs within a cell. Exemplarily, the network device sends the wakeup signal to one UE or multiple UEs within a preset cell, and each UE that receives the wakeup signal can wake up the second transceiver based on the wakeup signal.
In this way, some or all UEs within a cell can wake up the second transceivers based on the received wakeup signal, thereby saving the power consumption and battery life for all UEs in the cell. Moreover, the network device can broadcast or multicast the wakeup signal, thereby further saving the power consumption and battery life of the network device.
In some embodiments of this disclosure, when the UE monitors the wakeup signal based on the first transceiver of the UE, the second transceiver of the UE is in a first off state. Here, the first off state may be a fully-off state.
In some embodiments, when the first transceiver of the UE monitors the wakeup signal, the second transceiver of the UE is in a first off state, where the second transceiver in the first off state is configured to stop all behaviors of AS (Access Stratum).
Exemplarily, the second transceiver in the first off state is configured to select, but is not limited to, at least one of the following:
Here, the system message may be any kind of system message. For example, the system message may be SIB X, where X is an integer greater than or equal to 0. The SIB X may be SIB 1, SIB2, SIB3, or the like.
Here, when referring to that the second transceiver does not perform cell measurement. it includes not performing measurement on the cell where the UE is located and/or not performing measurement on neighboring cells of the cell where the UE is located. Here, the cell where the UE is located is the serving cell of the UE.
In some embodiments of this disclosure, when the UE monitors the wakeup signal based on the first transceiver, the second transceiver is in a fully-off state, so that the UE stops all bebaviors of AS. For example, it may include but is not limited to at least one operation of the second transceiver including: stopping cell selection or reselection, stopping PLMN reselection, stopping monitoring of paging message, stopping monitoring of system message, and stopping cell measurement. In this way, according to some embodiments of this disclosure. the behavior of the second transceiver is defined after introducing the first transceiver at the UE to monitor the paging message. Moreover, according to some embodiments of this disclosure, the second transceiver does not need to perform behavior of AS until detecting the wakeup signal by the first transceiver, thereby saving the power consumption and battery life of the UE.
In some other embodiments of this disclosure, when the UE monitors the wakeup signal based on the first transceiver of the UE, the second transceiver of the UE is in a second off state. Here, the second off state may be a partially-off state.
In some embodiments, when the first transceiver of the UE monitors the wakeup signal, the second transceiver of the UE is in the second off state, where the second transceiver in the second off state is configured to maintain part of the behaviors of AS.
Exemplarily, the second transceiver in the second off state is configured to select at least one of the following:
Here, when referring to that the second transceiver performs relaxation on the measurement of a cell, it may be implemented as that the second transceiver performs relaxation on the reference signal measurement of the cell where the UE is located. When referring to that the second transceiver performs relaxation on the measurement of a neighboring cell(s) of the cell, it may be implemented as that the second transceiver performs relaxation on the reference signal measurement(s) of the neighboring cell(s) of the cell where the UE is located. The cell where the UE is located is the serving cell of the UE. The neighboring cell includes a neighboring cell(s) of the serving cell where the UE is located. Here, the UE may perform relaxed measurement of the serving cell and/or the neighboring cell(s) based on the second transceiver, thereby achieving the effect of power saving.
In some embodiments of this disclosure, when the UE monitors the wakeup signal based on the first transceiver, the second transceiver is in the partially-off state, so that the UE maintains part of the behaviors of AS. For example, it may include but not limited to at least one operation of the second transceiver including performing a relaxed measurement on the cell where the UE is located, performing a relaxed measurement(s) on the neighboring cell(s), and stopping measurement on the neighboring cell(s) and/or the cell where the UE is located. In this way, according to some embodiments of this disclosure, the behavior of the second transceiver is defined after introducing the first transceiver at the UE to monitor the paging message. According to some embodiments of this disclosure, only some behaviors of AS can be maintained by the second transceiver before the wakeup signal is detected by the first transceiver, thereby also saving the power consumption and battery life of the UE.
It should be noted, those skilled in the art can understand that the methods according to some embodiments of this disclosure may be implemented alone or together with some methods according to other embodiments of this disclosure or some methods in related art.
In some embodiments, the method includes: receiving configuration information.
Step S21 includes: monitoring, based on the configuration information, the wakeup signal by using the first transceiver.
As shown in
In step S31, configuration information is received.
In step S32, the wakeup signal is monitored by using the first transceiver of the UE based on the configuration information.
In some embodiments of this disclosure, the first transceiver is the first transceiver in step S21, and the wakeup signal is the wakeup signal in step S21.
The configuration information includes but is not limited to at least one of the following:
Step S31 may include receiving the configuration information sent by the network device. For example, the UE may receive a notification message sent by the network device, where the notification message carries the configuration information. In some embodiments, the notification message may be a system message.
Here, the UE can receive the configuration information in any implementable manner. For example, the UE receives the configuration information when it is in the RRC connected state, or the UE in the RRC non-connected state receives the configuration information during an activated DRX duration of the DRX cycle.
In some embodiments, the period indicated in the period information may be a DRX cycle and/or an extended DRX cycle, where the extended DRX cycle may be a preset multiple of the DRX cycle.
In some other embodiments, the period indicated in the period information may be greater than or equal to a first duration. For example, the first duration may be 5.12 seconds, 10.24 seconds, or the like.
In some embodiments, the number of sending times indicated in the times information refers to the number of times the wakeup signal is repeatedly sent. For example, the times information is used to indicate that the number of times the wakeup signal is repeatedly sent within a preset time interval is N, where N is an integer greater than 1. In this way, by repeatedly sending the wakeup signal, the probability of the UE detecting the wakeup signal can be increased.
In some embodiments, the periodic monitoring mode may be a mode of monitoring at preset time intervals.
Some embodiments of this disclosure provide a monitoring method, which is performed by the UE and includes: monitoring the wakeup signal in the periodic monitoring mode based on the first transceiver. For example, the first transceiver of the UE may monitor the wakeup signal on the PDCCH channel every 5 seconds. In this way, according to some embodiments of this disclosure, the wakeup signal needs not to be always monitored through the first transceiver, and the first transceiver can monitor the wakeup signal at preset time intervals, thereby further saving the power consumption and battery life of the UE.
In some embodiments, the continuous monitoring mode may be a mode of continuous monitoring.
Some embodiments of this disclosure provide a monitoring method, which is performed by the UE and includes: monitoring the wakeup signal in the continuous monitoring mode based on the first transceiver. For example, the first transceiver of the UE continuously monitors the wakeup signal on the PDCCH. In this way, according to some embodiments of this disclosure, the wakeup signal can be continuously monitored, thereby reducing the probability of missing the wakeup signal and increasing the probability of monitoring the wakeup signal.
In some embodiments of this disclosure, the continuous monitoring mode may also be performed at a preset time interval, and the preset time interval in the continuous monitoring mode is smaller than the preset time interval in the periodic monitoring mode. For example, the periodic monitoring mode is a mode of monitoring at a first preset time interval, and the continuous monitoring mode is a mode of monitoring at a second preset time interval. where the first preset time interval is greater than the second preset time interval.
In some embodiments of this disclosure, the UE may monitor, using the first transceiver, the wakeup signal based on the configuration information sent by the network device. In this way, according to some embodiments of this disclosure, the wakeup signal can be monitored through the configuration of the network device, thereby facilitating the scheduling of resources by the network device.
In some embodiments, step S21 includes: monitoring the wakeup signal by using the first transceiver based on a pre-agreed protocol.
As shown in
In step S41, based on the pre-agreed protocol, the wakeup signal is monitored by using the first transceiver.
In some other embodiments, the pre-agreed protocol may be a protocol pre-negotiated between the UE and the network device.
This pre-agreed protocol stipulates at least one of the following:
The pre-agreed protocol is used to stipulate at least one of time-frequency domain information, scrambling information, period information, offset, frequency information (number of times) and monitoring mode information. The time-frequency domain information is used to indicate the time-frequency domain position for monitoring the wakeup signal; the scrambling information is used to indicate the scrambling information for monitoring the wakeup signal; the period information is used to indicate the period for monitoring the wakeup signal; the offset is used to indicate the time offset of the sending time of the wakeup signal relative to the starting time of the period; the frequency information is used to indicate the number of times the wakeup signal is sent; the monitoring mode information is used to indicate the monitoring mode for monitoring the wakeup signal. The time-frequency domain information, scrambling information, period, time offset, number of transmissions and monitoring mode of the wakeup signal agreed in the pre-agreed protocol can be same as or different from the time-frequency domain information, scrambling information, period, time offset, number of transmissions and monitoring mode of the wakeup signal configured by the network device, respectively.
In some embodiments of this disclosure, the UE can monitor the wakeup signal based on the first transceiver in a manner stipulated in the pre-agreed protocol, thereby facilitating unified agreement on the parameters used by the same type of UE to monitor the wakeup signal using the first transceiver.
It should be noted that, those skilled in the art can understand that the methods provided in some embodiments of this disclosure can be implemented alone or together with some methods in other embodiments of this disclosure or some methods in related art.
As shown in
In step S51, in response to the first transceiver receiving the wakeup signal, the second transceiver is woken up or the working mode of monitoring the wakeup signal based on the first transceiver is exited; the second transceiver is woken up in response to the UE having uplink data to be sent; the second transceiver is woken up in response to the UE being required to perform synchronization with network; the second transceiver is woken up in response to the UE receiving indication information of a non-access stratum (NAS); the second transceiver is woken up in response to a duration of the first transceiver monitoring the wakeup signal being greater than a preset duration.
In some embodiments of this disclosure. the first transceiver and the second transceiver may be the first transceiver and the second transceiver in step S21 respectively; and the wakeup signal may be the wakeup signal in step S21.
For example, if the UE receives the wakeup signal based on the first transceiver, it, based on the wakeup signal, wakes up the second transceiver of the UE or exits the working mode of monitoring the wakeup signal based on the first transceiver.
For example, if the UE determines that the UE has uplink data to be sent, it wakes up the second transceiver of the UE. The uplink data may be any kind of service data, or the uplink data may be any kind of information sent by the UE to the network device. For example, if the UE needs to send random access information to the base station, the second transceiver of the UE is woken up.
For example, it may be assumed that the UE is in a synchronized state with the network when using the second transceiver. For example, the UE may maintain a timer. After the timer expires, the UE may be considered to be out of synchronization with the network; at this time, the UE needs to turn on the second transceiver to perform synchronization with the network.
For example, if the UE determines that it needs to perform synchronization with the network, it wakes up the second transceiver of the UE. For example, if the UE determines that it needs to synchronize with the network in the time-frequency domain, it determines to wake up the second transceiver. The time-frequency domain synchronization includes: time synchronization and/or frequency synchronization. In this way, in some scenarios where the UE needs to perform synchronization with the network, such as when it needs to receive GPS signal, the UE can perform synchronization with the network by waking up the second transceiver of the UE.
For example, the UE receives NAS indication information and wakes up the second transceiver of the UE. Here, the NAS indication information may be, but is not limited to, an indication to perform PLMN reselection. The indication information may be any kind of information that can be sent by the NAS. For example, it may be indication information for mobility management, indication information indicating reporting of UE capabilities, or the like.
For example, the UE determines to wake up the second transceiver in response to that a duration from start of monitoring the wakeup signal based on the first transceiver to the current time exceeds a preset duration. Here, the preset duration may be greater than a second duration, and the second duration may be any duration, or may be the period of monitoring the wakeup signal, or may be a preset multiple of the period, or may be at least one DRX cycle. For example, the second duration is 5 seconds. In this way, if the UE monitors the wakeup signal based on the first transceiver for more than the preset duration, the first transceiver may not be able to detect the wakeup signal, or a paging message may be missed if the second transceiver is still not woken up. Accordingly, by waking up the second transceiver, the probability of missing paging message can be reduced and normal communication of the UE can be ensured.
In some embodiments, the preset duration may be preset by the network device.
In some other embodiments, the preset duration may be determined by the UE based on historical data. For example, the UE records at least once a third duration, where the third duration is the difference between the start time when the UE monitors the wakeup signal based on the first transceiver and the time when the UE wakes up the second transceiver. Accordingly, the UE determines the preset duration based on the third duration. Here, the third duration is historical data.
In some embodiments of this disclosure, the UE can wake up the second transceiver by monitoring the wakeup message based on the first transceiver; or the UE can also wake up the second transceiver in response to determining at least one of that it needs to send uplink data, needs to synchronize with the network, receives the NAS indication information, or is in a state where the time for monitoring the wakeup signal based on the first transceiver reaches the second preset duration. In this way, the wakeup of the second transceiver can be triggered in a variety of ways, and can be adapted to more scenarios of how to wake up the second transceiver after the first transceiver is introduced at the UE.
It should be noted that, those skilled in the art can understand that the methods provided in some embodiments of this disclosure can be implemented alone or together with some methods in other embodiments of this disclosure or some methods in related art.
In some embodiments of step S21, monitoring the wakeup signal based on the first transceiver of UE includes at least one of following:
As shown in
In step S61, the wakeup signal is monitored by using the first transceiver of the UE in response to the UE being in a preset RRC non-connected state; and/or, the wakeup signal is monitored by using the first transceiver of the UE in response to detecting a first triggering event.
In some embodiments of this disclosure, the first transceiver is the first transceiver in step S21, and the wakeup signal is the wakeup signal in step S21.
The preset RRC non-connected state may be a newly defined RRC non-connected state. For example, the preset RRC non-connected state of UE is RRC ultra-non-connected state, where the RRC ultra-non-connected state includes: RRC ultra-inactive state (RRC-ultra-INACTIVE) or RRC ultra-idle state (RRC-ultra-IDLE).
The preset RRC non-connected state may be independent of any existing RRC state, or may be a sub-state of an existing RRC state. For example, the RRC ultra-idle state (RRC-ultra-IDLE) may be a sub-state of RRC idle state (RRC-IDLE).
The UE being in the preset RRC non-connected state includes but not limited to one of the following:
Some embodiments of this disclosure provide a monitoring method, which is performed by the UE and includes one of the following:
For example, if the UE is in the ultra-idle state, the UE monitors the wakeup signal based on the first transceiver of the UE; or, if the UE is in the ultra-inactive state, the UE monitors the wakeup signal based on the first transceiver of the UE. Here, the UE being in the ultra-idle state may include but is not limited to: the UE switching from the RRC connected state to the RRC ultra-idle state, or the UE switching from the RRC idle state to the RRC ultra-idle state, or the like. The UE being in the RRC inactive state may include but is not limited to: the UE switching from the RRC connected state to the RRC inactive state, or the UE switching from the RRC inactive state to the RRC ultra-inactive state.
Some embodiments of this disclosure provide a monitoring method, which is performed by the UE and includes one of the following:
For example, if the UE switches from the RRC idle state to the RRC ultra-idle state, the wakeup signal is monitored based on the first transceiver of the UE; or, if the UE switches from the RRC inactive state to the RRC ultra-inactive state, the wakeup signal is monitored based on the first transceiver of the UE.
In this way, according to some embodiments of this disclosure, when the UE is in the RRC ultra non-connected state or switches from the RRC non-connected state to the RRC ultra non-connected state, the UE can monitor the wakeup signal based on the first transceiver, thereby saving the power consumption and battery life of the UE.
The first triggering event includes but is not limited to at least one of the following:
When referring to that the communication signal strength of the UE is greater than the preset strength, it may be that a signal strength of a signal received by the UE is greater than the preset strength.
For example, if the UE detects that the signal strength of the signal received by the UE is greater than the preset strength and/or determines that a position of the UE is in the central area of the cell where the UE is located, then the UE monitors the wakeup signal based on the first transceiver of the UE.
For example, if the UE does not receive downlink data within the first preset duration, the UE may enter a preset RRC non-connected state to reduce the power consumption of the UE.
In this way, according to some embodiments of this disclosure, if the UE detects that the signal strength of the signal received by the UE is greater than the preset strength, it can be determined that the communication quality of the UE is relatively good; and/or if the UE determines that the position of the UE is in the central area of the cell where the UE is located, it can also be determined that the communication quality of the UE will be relatively good. In this way, even if the first transceiver with relatively low power consumption is used to monitor the wakeup signal, the success rate of detecting the wakeup signal can be ensured. Moreover, because the wakeup signal is monitored by using the first transceiver with relatively low power consumption, rather than using the second transceiver with higher power consumption, the power consumption and battery life of the UE can be saved.
In some embodiments of this disclosure, the UE can enter the working mode of monitoring the wakeup signal using the first transceiver in response to switching from the RRC idle state to the RRC ultra-idle state or from the RRC inactive state to the RRC ultra-inactive state, or in response to detecting the first triggering event.
