As shown in Fig. 1, a method for transmitting system information provided by an embodiment of the present disclosure may be applied to a wireless communication system 100, which may include a user equipment 101 and a network device 102. The user equipment 101 is configured to support carrier aggregation and may be connected to multiple carrier components of the network device 102, including a primary carrier component and one or more secondary carrier components.

It should be understood that the above wireless communication system 100 can be applied to both low-frequency scenarios and high-frequency scenarios. The application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, worldwide interoperability for microwave access (WiMAX) communication system, cloud radio access network (CRAN) system, future fifth-generation (5G) system, new radio (NR) communication system or future evolved public land mobile network (PLMN) system, etc.

The user equipment 101 shown above may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent or a terminal device, etc. The user equipment 101 may have a wireless transceiver function, and it can communicate with one or more network devices of one or more communication systems (such as wireless communication) and receive network services provided by the network devices, where the network devices include but are not limited to the network device 102 shown in the figure.

Among them, the user equipment 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, etc.

The network device 102 may be an access network device (or access network point). Among them, the access network device refers to a device that provides network access functions, such as a radio access network (RAN) base station, etc. The network device 102 may specifically include a base station (BS), or a base station and a wireless resource management device for controlling the base station, etc. The network device 102 may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station, etc. The network device 102 may be a wearable device or a vehicle-mounted device. The network device 102 may also be a communication chip with a communication module.

For example, the network device 102 includes, but is not limited to, a next-generation base station (gnodeB, gNB) in 5G, an evolved node B (evolved node B, eNB) in an LTE system, a radio network controller (radio network controller, RNC), a node B (node B, NB) in a WCDMA system, a wireless controller under a CRAN system, a base station controller (basestation controller, BSC), a base transceiver station (base transceiver station, BTS) in a GSM system or a CDMA system, a home base station (for example, home evolved nodeB, or home node B, HNB), a baseband unit (baseband unit, BBU), a transmitting point (transmitting and receiving point, TRP), a transmitting point (transmitting point, TP) or a mobile switching center, etc.

In the relevant protocols, system information (SI) is divided into many types, for example, system information related to paging configuration, system information related to radio resource management (RRM) measurement, system information related to positioning, system information related to security alarm, and so on.

From the perspective of the mechanism by which the user equipment 101 updates the system information, the system information may include the following two categories:

The first type of system information requires the UE to be updated, thereby ensuring that the UE always retains a valid version of the system information.

For example, a UE in Radio Resource Control Idle (RRC_Idle) and RRC Inactive (RRC_Inactive) state shall ensure that it has at least the valid versions of the following system information: Master Information Block (MIB), System Information Block 1 (SIB1) to SIB4, SIB5 (if the UE supports E-UTRA), SIB11 (if the UE is configured For idle/inactive measurements), SIB12 (if the UE is capable of NR sidelink communication/discovery and is configured by the upper layer to receive or send NR sidelink communication/discovery), and valid versions of SIB13, SIB14 (if the UE is capable of V2X sidelink communication and is configured by the upper layer to receive or send V2X sidelink communication), SIB15 (if the UE is configured by the upper layer to report roaming failure related information), SIB16 (if the UE receives National Service Access Gateway NSAG information for cell reselection from the upper layer), SIB19 (if the UE accesses NR through a non-terrestrial network NTN).

For the second type of system information, the UE does not need to always maintain a valid version of the SI, and only needs to obtain the latest system information when necessary.

For example, positioning system information (posSIB), SIB6, SIB7 and SIB8. Among them, the UE will only obtain SIB6, SIB7 or SIB8 when the short messages indication field of the paging DCI indicates that there is security warning information. The UE will only obtain posSIB when the UE's upper layer requires the acquisition of positioning-related SIBs.

In addition, LP WUS configuration information may also be sent to user device 101 as a system information.

The user equipment 101 may obtain the LP WUS configuration information only when needed. For example, for a UE in the RRC_Idle state, it is not necessary to monitor the LP WUS, and therefore it is not necessary to always keep a valid version of the system information related to the LP WUS configuration information, and it can be obtained when needed. Based on this, it is necessary to know the timing when the UE obtains the system information related to the LP WUS configuration information, or to know when the UE needs to obtain the system information related to the LP WUS configuration information.

The present disclosure provides a method for transmitting system information, with reference to FIG. 2 , which is a method for transmitting system information according to an exemplary embodiment. As shown in FIG. 2 , the method includes steps S201 to S202, specifically:

Step S201: the network device 102 sends first system information.

Step S202, when the first condition is met, monitor the first system information sent by the network device 102, the first system information includes the low power wake-up signal LP WUS configuration information.

In some possible implementations, the user device 101 decides whether to monitor the first system information carrying the LP WUS configuration information based on whether the user device 101 satisfies the first condition.

In some possible implementations, the LP WUS configuration information includes one or more of the time domain resources, frequency domain resources, power information, and spatial domain information for sending the LP WUS. The spatial domain information may be used to indicate the transceiver beam information.

In some possible implementations, the first condition is related to a request of a higher layer of the user equipment 101 itself.

In one example, the first condition includes: the physical layer of the user equipment 101 receives a request from a higher layer to monitor LPWUS, that is, the higher layer of the user equipment 101 has a request to monitor LP WUS.

The upper layer may be an application layer, and the application layer may send a request to the physical layer to monitor LP WUS due to energy saving requirements. In this example, after receiving the request to monitor LP WUS from the upper layer, the physical layer needs to monitor the first system information carrying LP WUS configuration information before monitoring LP WUS to obtain valid LP WUS configuration information.

In another example, the first condition includes: a higher layer of the user equipment 101 determines that the channel quality measurement result is greater than or equal to a corresponding threshold value.

The high layer may be an RRC layer. In this example, when the channel quality measurement result is good, it is considered that the monitoring quality of the LP WUS is also good, and the state of monitoring the LP WUS can be switched to achieve energy saving. Before switching to the state of monitoring the LP WUS, the user equipment 101 needs to monitor the first system information carrying the LP WUS configuration information to obtain valid LP WUS configuration information.

In some possible implementations, the user equipment 101 is a user equipment in an RRC idle state.

In some possible implementations, after obtaining the first system information carrying the LP WUS configuration information, the user device 101 may be switched to an energy-saving state of monitoring the LP WUS, and monitor the LP WUS at a corresponding time-frequency position through a low-power receiver according to the time-frequency resources configured by the LP WUS configuration information. In the state of monitoring the LP WUS, the main receiver may be in a sleep state, thereby achieving energy saving of the user device 101.

In some possible implementations, when the first system information related to the configuration information of the LP WUS changes, the network device 102 does not use a modification period to broadcast the updated first system information related to the configuration information of the LP WUS.

In one example, in addition to the first system information related to the configuration information of the LP WUS, the system information for the Earthquake and Tsunami Warning System (ETWS), the system information for the Commercial Mobile Alert System (CMAS), the system information for positioning assistance data, and the SI information for some specified non-terrestrial network (NTN) specific information, the updated SI information can be broadcast in the modification period after the period for sending the SI change indication.

In some possible implementations, when the first system information related to the configuration information of the LP WUS changes, the change of the LP WUS configuration information will not be indicated through the system information update indication in the paging DCI.

In one example, when the first system information related to the configuration information of the LP WUS changes, the system information update indication bit (e.g., the short messages indication field) in the paging DCI is still the first bit value, and the first bit value is used to indicate that the system information has not changed. For example, the first bit value is 0.

In the disclosed embodiment, when certain conditions are met, the user device 101 monitors the first system information carrying LP WUS configuration information sent by the network device 102, and promptly obtains the required first system information, so as to accurately monitor LP WUS according to the valid LP WUS configuration information in an energy-saving state, thereby ensuring energy-saving effects.

The present disclosure provides a method for transmitting system information, with reference to FIG3 , which is a method for transmitting system information according to an exemplary embodiment. As shown in FIG3 , the method includes steps S301 to S302, specifically:

In step S301, the network device 102 broadcasts first system information, and the first system information includes low power wake-up signal LP WUS configuration information.

Step S302: When a first condition is met, monitor the first system information broadcasted by the network device 102.

In some possible implementations, the network device 102 may broadcast the first system information carrying LP WUS configuration information at a set period.

In some possible implementations, the first condition includes: a request to monitor LP WUS exists in a higher layer of the user equipment 101. For example, a physical layer of the user equipment 101 receives a request to monitor LP WUS sent by a higher layer.

In some possible implementations, the first condition includes: when the channel quality measurement result of the user equipment 101 is greater than or equal to the corresponding parameter threshold value.

In some possible implementations, after obtaining the first system information carrying the LP WUS configuration information, the user equipment 101 may be switched to a state of monitoring the LP WUS, and monitor the LP WUS at a corresponding time-frequency position through a low-power receiver according to the time-frequency resources configured by the LP WUS configuration information. In the state of monitoring the LP WUS, the main receiver may be in a sleep state, thereby achieving energy saving of the user equipment 101.

In the disclosed embodiment, the user equipment 101 does not need to send SI request information, the network device 102 actively broadcasts the first system information, and the user equipment 101 monitors the required first system information when the first condition is met.

The present disclosure provides a method for transmitting system information. Referring to FIG. 4 , FIG. 4 is a method for transmitting system information according to an exemplary embodiment. As shown in FIG. 4 , the method includes steps S401 to S403, specifically:

Step S401, when the first condition is met, the user device 101 sends a system information SI request message (SI request) to the network device 102, and the SI request message is used to request the first system information including the LP WUS configuration information.

Step S402: after receiving the SI request information, the network device 102 sends the first system information to the user equipment 101.

Step S403, the user device 101 monitors the first system information sent by the network device 102, and the first system information includes low power wake-up signal LP WUS configuration information.

In the disclosed embodiment, before monitoring the required first system information, the user equipment 101 needs to first send SI request information to the network device 102, and then monitor the network device 102 sending the corresponding first system information based on the SI request information.

The present disclosure provides a method for monitoring system information, which is performed by a user equipment 101. Referring to FIG. 5 , FIG. 5 is a method for monitoring system information according to an exemplary embodiment. As shown in FIG. 5 , the method includes step S501, specifically:

Step S501, when the first condition is met, the user device 101 monitors the first system information sent by the network device 102, and the first system information includes the low power wake-up signal LP WUS configuration information.

In some possible implementations, the first condition includes: a higher layer of the user equipment 101 has a request to monitor the LP WUS. The higher layer may be an application layer, and the application layer may send a request to monitor the LP WUS to the physical layer due to energy saving requirements. After receiving the request to monitor the LP WUS from the higher layer, the physical layer needs to monitor the first system information carrying the LP WUS configuration information before monitoring the LP WUS to obtain valid LP WUS configuration information.

In some possible implementations, the first condition includes: a higher layer of the user equipment 101 determines that a channel quality measurement result is greater than or equal to a corresponding threshold value. When the channel quality measurement result is good, it is considered that the monitoring quality of the LP WUS is also good, and it can be switched to a state of monitoring the LP WUS to achieve energy saving. Before switching to a state of monitoring the LP WUS, the user equipment 101 needs to monitor the first system information carrying the LP WUS configuration information to obtain valid LP WUS configuration information.

The user equipment 101 is a user equipment in an RRC idle state.

The embodiment of the present disclosure provides a method for monitoring system information, which is performed by the user equipment 101. The method includes step S501', specifically:

Step S501', when the first condition is met, the user device 101 monitors the first system information broadcast by the network device 102, and the first system information includes the low power wake-up signal LP WUS configuration information.

The embodiment of the present disclosure provides a method for monitoring system information, which is performed by the user equipment 101. Referring to FIG. 6 , FIG. 6 is a method for monitoring system information according to an exemplary embodiment. As shown in FIG. 6 , the method includes steps S601 to S602, specifically:

Step S601, when the first condition is met, the user device 101 sends a system information SI request message to the network device 102, and the SI request message is used to request the first system information including the LP WUS configuration information.

Step S602 : the user equipment 101 monitors the first system information sent by the network equipment 102 .

In some possible implementations, the first condition includes: a higher layer of the user device 101 has a request to listen to LP WUS.

The embodiment of the present disclosure provides a method for monitoring system information, which is performed by a user equipment 101. The method includes steps S601 to S602, wherein the first condition includes: when the channel quality measurement result of the user equipment 101 is greater than or equal to the corresponding parameter threshold value.

The channel quality measurement result is a measurement result corresponding to a reference signal of a serving cell.

In some possible implementations, the user equipment 101 measures a reference signal (RS) of a serving cell to obtain a channel quality measurement result.

In some possible implementations, the channel quality measurement results may be represented by Reference Signal Receiving Power (RSRP).

In some possible implementations, the reference signal is a channel state information reference signal CSI-RS.

In some possible implementations, the parameter threshold is defined by a protocol or configured by a network device.

In one example, a value corresponding to the parameter threshold value is defined by a protocol, or a determination method is defined. For example, the parameter threshold value may be related to: a difference between the transmit power of the reference signal and the transmit power of the LP WUS, or the parameter threshold value may be related to the sensitivity of a receiver receiving the LP WUS.

In another example, the network device 102 may configure a value corresponding to the parameter threshold for the user equipment 101. Alternatively, after the network device 102 determines the parameter threshold in a manner defined by the protocol, it sends indication information carrying the parameter threshold to the user equipment 101.

The sensitivity of the receiver used to receive LP WUS.

In this implementation, the sensitivity of the low power receiver of the user device 101 receiving the LP WUS and the sensitivity of the main receiver can be obtained and recorded during the terminal factory test.

In this implementation, the sensitivity of the low-power receiver is generally lower than that of the main receiver. Therefore, under the same power condition, the coverage performance of the wake-up signal for the low-power receiver is poor.

In this implementation, when the channel quality measurement result is good, it is considered that the monitoring quality of LP WUS is also good, and the state of monitoring LP WUS can be switched to achieve energy saving.

To facilitate understanding of this embodiment, a specific example is given below:

Assume that the sensitivity of the low power receiver of the user equipment 101 is -80 decibel house (dbm), which can express the minimum receiving power of the low power receiver.

When the user equipment 101 is in the RRC idle state, the main receiver is turned on to receive SSB or paging information.

When the user device 101 measures the RSRP value of SSB to be -100dbm, the user device 101 also receives the LP WUS broadcasted by the network device 102, which has a power offset of +12dbm (difference in transmit power) compared to SSB, that is, the transmit power of LP WUS is 12dbm higher than that of SSB. If the number of LP WUS repetitions is 4, it is equivalent to a repetition gain of 6dB.

According to the protocol definition, the user device 101 estimates that the receiving power of LP WUS is: -100+12+6=-82dbm, which has not reached the -80dbm corresponding to the sensitivity of the low power receiver. Therefore, the user device 101 can determine that the low power receiver does not need to be turned on.

When user equipment 101 measures the RSRP value of SSB to be -95dbm, the difference between the SSB transmit power and the LP WUS transmit power is still +12dbm, and the repetition gain is still 6dB.

According to the protocol definition, the user device 101 estimates the receiving power of LP WUS to be: -95+12+6=-77dbm, which reaches the -80dbm corresponding to the sensitivity of the low power receiver. Therefore, the user device 101 can turn on the low power receiver.

Based on the same concept as the above method embodiment, the embodiment of the present disclosure also provides a device for monitoring system information, which can have the functions of the user equipment 101 in the above method embodiment, and can be used to execute the steps performed by the user equipment 101 provided by the above method embodiment. The function can be implemented by hardware, or by software or hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above functions.
