This application is the U.S. national phase of PCT Application PCT/CN2019/107776 filed on Sep. 25, 2019, which claims the priority of Chinese Application No. 201811131916.5, filed on Sep. 27, 2018, the disclosures of which are incorporated in their entireties by reference herein.
The present disclosure relates to the field of communication application technologies, and in particular to a terminal state transition method, a network device and a terminal.
In the New Radio (NR) system of the 5th generation wireless system (5G), the power-saving design of a user equipment (UE, also referred as terminal) becomes very necessary. The main reason is that the 5G supports larger bandwidth and more complex services, and an optimized power-saving design can save power consumption of the terminal and extend battery life, thereby improving user experience. In the related art, a common power-saving method is to keep UE in a sleep state as much as possible. Specifically, when traffic arrives at a UE, the UE can switch to an active state; while when no traffic arrives at the UE, the UE enters a sleep state. A wakeup signal is an indication signal for the terminal to switch from the sleep state to the active state. However, in the related art, monitoring and resources of the wakeup signal are all periodic, such as binding with a transmission cycle of the discontinuous reception (DRX). The wakeup method based on the wakeup signal is also periodic, and the periodic wakeup method is not conducive to rapid change of the UE's operation state, and thus is not conducive to matching the user's actual service status.
One object of the present disclosure is to provide a terminal state transition method, a network device and a terminal, which can solve problems that the method of periodically waking up terminals in the related art is not conducive to rapid change of the UE's operation state, and thus is not conducive to matching the users actual service status.

The embodiments of the present disclosure have the following beneficial effects:
In the foregoing technical solutions of the embodiments of the present disclosure, by transmitting configuration information of the wakeup signal monitoring window to the terminal and transmitting the wakeup signal in the wakeup signal monitoring window in case of detecting arrival of data traffic, the terminal enters the wakeup state from the non-wakeup state in case that the terminal detects the wakeup signal in the wakeup signal monitoring window. In the embodiment of the present disclosure, the wakeup signal is transmitted once the data traffic is reached, so that the terminal enters the wakeup state, thereby realizing a rapid change of the terminal's operation state, and then further matching the terminal's operation state with the user's actual service state.
In order to make technical problems to be solved, technical solutions and the advantages of the present disclosure more apparent, the present disclosure will be described hereinafter in a clear and complete manner in conjunction with the drawings and embodiments.
The main meaningless power consumption of a terminal lies in monitoring of physical downlink control channel (PDCCH). Since the terminal cannot predict arrivals of downlink data, a more conservative configuration is to allow UE to continuously monitor PDCCH in each slot, but actual service cannot be continuous, thus, the often do a lot of ineffective PDCCH monitoring, which consumes a lot of battery energy.
An effective power-saving technology is DRX, which is a downlink discontinuous reception technology, which is divided into two processes including: DRX_ON and DRX_OFF. The UE only detects PDCCH within DRX_ON time window and is in a sleep state during DRX-OFF. Such technology is applicable to both Radio Resource Control (RRC) connected state and RRC idle state. More specifically, in 5G NR, such technology may be applied in three states: RRC connected state (RRC_Connected), RRC inactive state (RRC_inactive) and RRC idle state (RRC_IDLE). The wakeup technology based on periodic DRX introduces wakeup signals on the basis of DRX. The main motivation is that when traffic is sparse (in many cases, there is no data in DRX-ON stages), UE still needs to perform DCCH detection, which cause unnecessary power consumption. The wakeup signal is usually transmitted before DRX-ON to notify the UE whether data arrives in a current or subsequent DRX cycle. If the UE detects the wakeup signal, the UE is waken up, otherwise the UE, continues keeping in the sleep state and does not need to be waken up to monitor PDCCH.
Since DRX configuration in the related art is periodic, DRX-ON and DRX-OFF have a preset time length, which is not conducive to matching of actual services. In case that a DRX cycle is too short, the power saving effect of the UE is limited; in case that the DRX cycle is too long, it will affect transmission delay of data packets as downlink data may arrive at any time.
In view of this, one embodiment of the present disclosure provides a terminal state transition method, which is applied to a network device such as a base station. As shown in
Step 101: transmitting configuration information of a wakeup signal monitoring window to a terminal.
Here, the wakeup signal monitoring window may be periodic or aperiodic. The foregoing wakeup signal monitoring window may be semi-statically configured by the network device, or may be dynamically indicated by preset signaling.
In case that the foregoing wakeup signal monitoring window is semi-statically configured by the network device, the foregoing configuration information includes time-frequency location information of the wakeup signal monitoring window and resource allocation information of a wakeup signal.
In case that the foregoing wakeup signal monitoring window is dynamically indicated by preset signaling, the foregoing configuration information includes time-frequency location information of the wakeup signal monitoring window. Optionally, the foregoing configuration information further includes resource allocation information of a wakeup signal.
Each wakeup signal monitoring window includes at least one wakeup signal resource. Each wakeup signal resource includes one wakeup signal or multiple same wakeup signals (repetition of multiple wakeup signals). The foregoing wakeup signal is used to instruct the terminal to enter a wakeup state from a non-wakeup state. The non-wakeup state includes an inactive state or a sleep state. The wakeup state refers to an active state in which operations such as data reception or RRM measurement can be performed. The terminal is in the non-wakeup state in a non-wakeup signal monitoring window, and detects the wakeup signal only in a wakeup signal monitoring window.
The time-frequency location information of the wakeup signal monitoring window may be preset. That is, different wakeup signal monitoring windows may be semi-statically configured based on types of wakeup signals, or may be dynamically indicated through preset signaling, such as dynamically indicated through downlink control information (DCI) or sleep indication signal.
In the embodiments of the present disclosure, different types of wakeup signals are corresponding to different wakeup signal monitoring window configurations. The types of wakeup signals may include at least one of waveform, digital baseband sequence, reference signal, or physical channel.
Step 102: in case of detecting arrival of data traffic, transmitting a wakeup signal in the wakeup signal monitoring window.
Here, transmission of the wakeup signal is determined according to the arrival of the data traffic. In the terminal state transition method of the embodiment of the present disclosure, by transmitting configuration information of the wakeup signal monitoring window to the terminal and transmitting the wakeup signal in the wakeup signal monitoring window in case of detecting arrival of data traffic, the terminal enters the wakeup state from the non-wakeup state in case that the terminal detects the wakeup signal in the wakeup signal monitoring window. In the embodiment of the present disclosure, the wakeup signal is transmitted once the data traffic is reached, so that the terminal enters the wakeup state, thereby realizing a rapid change of the terminal's operation state, and then further matching the terminal's operation state with the user's actual service state.
Further, as an optional implementation, the transmitting configuration information of a wakeup signal monitoring window to a terminal of the foregoing step 101, includes:
The resource allocation information refers to resource allocation information of the wakeup signal in the wakeup signal monitoring window. The time-frequency location information includes time-domain location information and frequency-domain location information. In the embodiments of the present disclosure, different types of wakeup signals are corresponding to different wakeup signal monitoring window configurations. The types of wakeup signals may include at least one of waveform, digital baseband sequence, reference signal or physical channel.
Specifically, in case that the type of the wakeup signal is an analog waveform, according to a length of the wakeup signal, one or more wakeup signal monitoring windows are configured in each time unit or one wakeup signal monitoring window is configured in every N1 time units, where N1 is an integer greater than 1.
The foregoing time unit is specifically a slot in a radio transmission frame.
For example, in case that a length of the wakeup signal is less than or equal to one slot, one or more wakeup signal monitoring windows may be configured in each time unit; in case that a length of the wakeup signal is greater than one slot, one wakeup signal monitoring window may be configured in every N1 time units.
In addition, in case that a monitoring period of the wakeup signal is very short, such as one slot, then, a low-power receiver is required, and a binary on-off keying modulation (00K) waveform sequence is used as the wakeup signal, thereby ensuring that the UE is in a low-power consumption state.
In this implementation, different wakeup signal monitoring windows are semi-statically configured based on the types of wakeup signals. Generally, one wakeup signal monitoring window may be configured in every N time units, and location and an offset value (such as K slots) of a starting boundary of the wakeup signal may be indicated through RRC signaling.
N is a positive integer; K is greater than or equal to 0 and less than or equal to N−1.
And/or, in case that the type of the wakeup signal is a baseband signal, one wakeup signal monitoring window is configured in every N2 time units, where N2 is an integer greater than or equal to 1. The baseband signal includes at least one of a digital baseband sequence, a reference signal and a physical channel.
The time unit is a slot in a radio transmission frame.
In addition, in case that a monitoring period of the wakeup signal is long, such as greater than one slot, then, the wakeup signal may use a reference signal or PDCCH. At this point, time domain resources of one or more symbols are defined as a transmission window of the wakeup signal.
Optionally, in case that the type of the wakeup signal is an analog waveform, when a length of the wakeup signal is less than one time unit, a time interval between two adjacent wakeup signal monitoring windows is less than or equal to one time unit.
Here, the time interval between two adjacent wakeup signal monitoring windows is configured to be less than or equal to one time unit, which can ensure that the terminal enters the wakeup state at any time.
As another optional implementation, the transmitting configuration information of a wakeup signal monitoring window to a terminal of the foregoing step 101, includes:
Optionally, in this implementation, resource allocation information of the wakeup signal may also be transmitted to the terminal through the downlink control information (DCI) or the sleep indication signal. The resource allocation information refers to resource allocation information of the wakeup signal in the wakeup signal monitoring window.
In this implementation, time-frequency location of each wakeup signal monitoring window is dynamically variable and is not preset. For example, DCI is used to indicate time or time-frequency location for a next detection of the wakeup signal, or time-frequency location of a next wakeup signal monitoring window is determined by a sleep indication signal at an end of the last active state, or a timer is started at an end position of the last active time and UE monitors the wakeup signal after the timers expires.
In addition, this implementation may also be combined with the foregoing implementation. For example, the sleep indication signal may indicate whether to detect the wakeup signal in a next preset monitoring window, or may instruct UE to skip detection in multiple consecutive wakeup signal monitoring windows.
Optionally, after transmitting the wakeup signal in the wakeup signal monitoring window, the method further includes:
Further, after transmitting the wakeup signal in the wakeup signal monitoring window, the method further includes:
The sleep indication signal is used to instruct the terminal to enter the non-wakeup state from the wakeup state. The sleep indication signal may be DCI or medium access control (MAC) signaling; or bits of the sleep indication signal are carried in the DCI or MAC signaling, or may also be carried in a physical downlink shared channel (PDSCH) or other physical signals.
As an alternative, the network device may further indicate remaining transmission time Ts through downlink control information. In case that the remaining transmission time Ts is 0 or in case that the remaining transmission time Ts is 0 after a period of time has passed from receiving the remaining transmission time Ts, the terminal automatically enters the sleep state. The network device may further instruct the terminal to enter the sleep state through a load indication. Specifically, in case that the load indication is empty, the terminal enters the sleep state.
In the embodiment of the present disclosure, the network device transmits the wakeup signal according to location of the wakeup signal resource and arrival of the data traffic, and the UE searches and monitors the wake-up signal according to the configured monitoring window. In case that the UE is in the active state, the base station no longer transmits a wakeup signal; meanwhile, the UE does not monitor the wakeup signal. The embodiments of the present disclosure can help the UE to track service changes in real time, and reduce monitoring of PDCCH as much as possible, and reduce consumption of battery energy.
In the terminal state transition method of the embodiment of the present disclosure, by transmitting configuration information of the wakeup signal monitoring window to the terminal and transmitting the wakeup signal in the wakeup signal monitoring window in case of detecting arrival of data traffic, the terminal enters the wakeup state from the non-wakeup state in case that the terminal detects the wakeup signal in the wakeup signal monitoring window. In the embodiment of the present disclosure, the wakeup signal is transmitted once the data traffic is reached, so that the terminal enters the wakeup state, thereby realizing a rapid change of the terminal's operation state, and then further matching the terminal's operation state with the user's actual service state.
As shown in
Step 401: obtaining configuration information of a wakeup signal monitoring window.
Here, the wakeup signal monitoring window may be periodic or aperiodic. The foregoing wakeup signal monitoring window may be semi-statically configured by the network device, or may be dynamically indicated by preset signaling.
In case that the foregoing wakeup signal monitoring window is semi-statically configured by the network device, the foregoing configuration information includes time-frequency location information of the wakeup signal monitoring window and resource allocation information of a wakeup signal.
In case that the foregoing wakeup signal monitoring window is dynamically indicated by preset signaling, the foregoing configuration information includes time-frequency location information of the wakeup signal monitoring window. Optionally, the foregoing configuration information further includes resource allocation information of a wakeup signal.
Each wakeup signal monitoring window includes at least one wakeup signal resource. Each wakeup signal resource includes one wakeup signal or multiple same wakeup signals (repetition of multiple wakeup signals). The foregoing wakeup signal is used to instruct the terminal to enter a wakeup state from a non-wakeup state. The non-wakeup state includes an inactive state or a sleep state. The wakeup state refers to an active state in which operations such as data reception or RRM measurement can be performed. The terminal is in the non-wakeup state in a non-wakeup signal monitoring window, and detects the wakeup signal only in a wakeup signal monitoring window.
The time-frequency location information of the wakeup signal monitoring window may be preset. That is, different wakeup signal monitoring windows may be semi-statically configured based on types of wakeup signals, or may be dynamically indicated through preset signaling, such as dynamically indicated through downlink control information (DCI) or sleep indication signal.
In the embodiments of the present disclosure, different types of wakeup signals are corresponding to different wakeup signal monitoring window configurations. The types of wakeup signals may include at least one of waveform, digital baseband sequence, reference signal, or physical channel.
The step 401 specifically includes:
Specifically, the first timer is started at the end of the wakeup state; when the first timer expires, the wakeup signal is monitored. That is, time domain location information of the wakeup signal monitoring window is determined according to the end position of the wakeup state plus the timing duration of the first timer.
Step 402: performing wakeup signal detection processing in the wakeup signal monitoring window according to the configuration information.
Here, the terminal is in the non-wakeup state in a non-wakeup signal monitoring window, and detects the wakeup signal only in a wakeup signal monitoring window.
Step 403: in case that a wakeup signal is detected in the wakeup signal monitoring window, entering a wakeup state from a non-wakeup state.
Further, after entering a wakeup state from a non-wakeup state, the method further includes:
Further, after entering a wakeup state from a non-wakeup state, the method further includes:
Specifically, after performing synchronization and/or channel tracking according to the dedicated reference signal, PDCCH for scheduling data may be detected, and transmission of the data traffic may be performed.
Further, after entering a wakeup state from a non-wakeup state, the method further includes:
Specifically, before performing one or multiple RRM measurements or during process of performing one or multiple RRM measurements, synchronization and/or channel tracking is performed according to a dedicated reference signal, and an RRM measurement report is generated.
The performing multiple radio resource management (RRM) measurements to generate an RRM measurement report, includes:
Further, after entering a wakeup state from a non-wakeup state, the method further includes:
The sleep indication signal is used to instruct the terminal to enter the non-wakeup state from the wakeup state. The sleep indication signal may be DCI or medium access control (MAC) signaling; or bits of the sleep indication signal are carried in the DCI or MAC signaling, or may also be carried in a physical downlink shared channel (PDSCH) or other physical signals.
Or, in case that a timing duration of a second timer reaches a preset duration, the terminal enters the non-wakeup state from the wakeup state.
A timing starting point of the second timer may be a slot where the last PDCCH or feedback ACK signal is received.
Or, in case that a remaining transmission time indicated by downlink control information (DCI) is zero, the terminal enters the non-wakeup state from the wakeup state.
The network device may further indicate remaining transmission time Ts through downlink control information. In case that the remaining transmission time Ts is 0 or in case that the remaining transmission time Ts is 0 after a period of time has passed from receiving the remaining transmission time Ts, the terminal automatically enters the sleep state.
Or, in case that information indicated by a load indication is empty, the terminal enters the non-wakeup state from the wakeup state.
The network device instructs the terminal to enter the sleep state through the load indication. In case that the load indication is empty, it indicates that there is no follow-up information, and then the terminal enters the sleep state.
In the embodiment of the present disclosure, the terminal continuously monitors the wakeup signal (an interval between wakeup signal monitoring windows is small, such as less than one slot). As shown in
An aperiodic wakeup process of the terminal in the RRC connected state according to one embodiment of the present disclosure is specifically described hereinafter with reference to
In case that data traffic of a UE is burst and irregular, it is difficult for a base station to configure a periodic DRX to match an actual service process, thus it is necessary to use aperiodic DRX configuration. At this point, there is no configuration parameter of DRX, and only sleep and wakeup of the UE is dynamically controlled. It is needed to configure a wakeup signal and a sleep indication signal at the same time, to complete process conversion of aperiodic wakeup.
