Description

Method, device and readable storage medium for monitoring system information Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, device, and readable storage medium for monitoring system information. Background Art

[0002] The Low Power Wake-Up Signal (LP WUS) was introduced in Release 18 (R18) of the 3rd Generation Partnership Project (3GPP). A base station sends an LP WUS to a user equipment (UE) to wake it up. The UE can use a separate low-power receiver to listen for and receive the LP WUS. Upon receiving the LP WUS, it wakes up the main receiver to transmit and receive data, thereby saving energy. The LP WUS configuration information can be used as system information, and the timing for the UE to obtain this system information is required.

[0045] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0046] As shown in Figure 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. User equipment 101 is configured to support carrier aggregation and may be connected to multiple component carriers of network device 102, including a primary component carrier and one or more secondary component carriers.

[0047] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems.

[0048] 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 wireless transceiver functions, and may be capable of communicating (e.g., wireless communication) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

[0049] 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, an in-vehicle device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, etc.

[0050] The network device 102 may be an access network device (or access network point). An access network device refers to a device that provides network access functionality, such as a radio access network (RAN) base station. The network device 102 may specifically include a base station (BS), or a base station and a radio resource management device for controlling the base station. 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. The network device 102 may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.

[0051] For example, the network device 102 includes but is not limited to: the next generation base station (gnodeB, gNB) in 5G, the evolved node B (eNB) in the LTE system, the radio network controller (RNC), the node B (NB) in the WCDMA system, the wireless controller under the CRAN system, the base station controller (BSC), the base transceiver station (BTS) in the GSM system or the CDMA system, the home base station (for example, home evolved nodeB, or home node B, HNB), the baseband unit (BBU), the transmission point (TRP), the transmitting point (TP) or the mobile switching center, etc.

[0052] In relevant protocols, system information (SI) is divided into multiple types, such as 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 alarms, and so on.

[0053] From the perspective of the mechanism by which the user equipment 101 updates system information, the system information may include the following two categories:

[0054] 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.

[0055] For example, a UE in Radio Resource Control Idle (RRC_Idle) and RRC Inactive (RRC_Inactive) state shall ensure that it has at least 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 measurement), 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 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), and SIB19 (if the UE accesses NR through a non-terrestrial network NTN).

[0056] 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.

[0057] For example, positioning system information (posSIB), SIB6, SIB7, and SIB8. The UE will only obtain SIB6, SIB7, or SIB8 if the short messages indication field in the paging DCI indicates security alert information. The UE will only obtain posSIBs if its upper layers request it to obtain positioning-related SIBs.

[0058] In addition, the LP WUS configuration information may also be sent to the user equipment 101 as a kind of system information.

[0059] User equipment 101 may obtain LP WUS configuration information only when needed. For example, a UE in the RRC_Idle state does not need to monitor the LP WUS and therefore does not need to always maintain a valid version of system information related to the LP WUS configuration information. It can simply obtain the information when needed. Therefore, it is necessary to know when the UE obtains system information related to the LP WUS configuration information, or in other words, when the UE needs to obtain system information related to the LP WUS configuration information.

[0060] The present disclosure provides a method for transmitting system information. Referring to FIG. 2 , FIG. 2 shows a method for transmitting system information according to an exemplary embodiment. As shown in FIG. 2 , the method includes steps S201 to S202. Specifically,

[0061] In step S201 , the network device 102 sends first system information.

[0062] Step S202: When a first condition is met, monitoring first system information sent by the network device 102, where the first system information includes low power wake-up signal LP WUS configuration information.

[0063] In some possible implementations, the user equipment 101 determines whether to monitor the first system information carrying the LP WUS configuration information based on whether the user equipment 101 satisfies the first condition.

[0064] In some possible implementations, the LP WUS configuration information includes one or more of time domain resources, frequency domain resources, power information, and spatial domain information for sending the LP WUS, wherein the spatial domain information may be used to indicate transceiver beam information.

[0065] In some possible implementations, the first condition is related to a request from a higher layer of the user equipment 101 itself.

[0066] In an example, the first condition includes: the physical layer of the user equipment 101 receives a request from a higher layer to monitor the LPWUS, that is, the higher layer of the user equipment 101 has a request to monitor the LPWUS.

[0067] The higher layer may be an application layer, which may send a request to the physical layer to monitor the LP WUS due to energy conservation requirements. In this example, after receiving the request from the higher layer to monitor the LP WUS, 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.

[0068] 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.

[0069] The higher layer may be an RRC layer. In this example, when the channel quality measurement result is good, the monitoring quality of the LP WUS is considered good, and the user equipment 101 may switch to the LP WUS monitoring state to achieve energy saving. Before switching to the LP WUS monitoring state, the user equipment 101 needs to monitor the first system information carrying the LP WUS configuration information to obtain valid LP WUS configuration information.

[0070] In some possible implementations, the user equipment 101 is a user equipment in an RRC idle state.

[0071] In some possible implementations, after obtaining the first system information carrying the LP WUS configuration information, the user equipment 101 may switch to an energy-saving state for monitoring the LP WUS. Based on the time-frequency resources configured in the LP WUS configuration information, the user equipment 101 may monitor the LP WUS at the corresponding time-frequency location using a low-power receiver. While monitoring the LP WUS, the primary receiver may be in a sleep state, thereby achieving energy conservation for the user equipment 101.

[0072] In some possible implementations, when the first system information related to the configuration information of the LP WUS is changed, 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.

[0073] 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.

[0074] 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 is not indicated through a system information update indication in the paging DCI.

[0075] 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 still has a first bit value, which is used to indicate that the system information has not changed. For example, the first bit value is 0.

[0076] In the embodiment of the present disclosure, when certain conditions are met, the user equipment 101 monitors the first system information carrying the LP WUS configuration information sent by the network device 102, and promptly obtains the required first system information, so as to accurately monitor the LP WUS according to the valid LP WUS configuration information in the energy-saving state, thereby ensuring energy-saving effects.

[0077] An embodiment of the present disclosure provides a method for transmitting system information. Referring to FIG. 3 , FIG. 3 is a method for transmitting system information according to an exemplary embodiment. As shown in FIG. 3 , the method includes steps S301 to S302. Specifically:

[0078] Step S301: The network device 102 broadcasts first system information, where the first system information includes low power wake-up signal LP WUS configuration information.

[0079] Step S302: When a first condition is met, monitoring first system information broadcast by the network device 102.

[0080] In some possible implementations, the network device 102 may broadcast the first system information carrying the LP WUS configuration information according to a set period.

[0081] In some possible implementations, the first condition includes: a higher layer of the user equipment 101 has a request to monitor the LP WUS. For example, the physical layer of the user equipment 101 receives a request to monitor the LP WUS sent by a higher layer.

[0082] In some possible implementations, the first condition includes: a channel quality measurement result of the user equipment 101 is greater than or equal to a corresponding parameter threshold.

[0083] In some possible implementations, the user equipment 101 is a user equipment in an RRC idle state.

[0084] In some possible implementations, after obtaining the first system information carrying the LP WUS configuration information, the user equipment 101 may switch to a state of monitoring the LP WUS. Based on the time-frequency resources configured in the LP WUS configuration information, the user equipment 101 may monitor the LP WUS at the corresponding time-frequency location using a low-power receiver. While monitoring the LP WUS, the primary receiver may be in a sleep state, thereby saving energy for the user equipment 101.

[0085] In the embodiment of the present disclosure, 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.

[0086] An embodiment of the present disclosure provides a method for transmitting system information. Referring to FIG. 4 , FIG. 4 shows a method for transmitting system information according to an exemplary embodiment. As shown in FIG. 4 , the method includes steps S401 to S403. Specifically:

[0087] Step S401: When a first condition is met, the user equipment 101 sends a system information SI request message (SI request) to the network device 102. The SI request message is used to request first system information including LP WUS configuration information.

[0088] Step S402 : After receiving the SI request information, the network device 102 sends the first system information to the user equipment 101 .

[0089] Step S403 : The user equipment 101 monitors first system information sent by the network device 102 , where the first system information includes low power wake-up signal LP WUS configuration information.

[0090] In some possible implementations, the first condition includes: a higher layer of the user equipment 101 has a request to monitor the LP WUS. For example, the physical layer of the user equipment 101 receives a request to monitor the LP WUS sent by a higher layer.

[0091] In some possible implementations, the first condition includes: a channel quality measurement result of the user equipment 101 is greater than or equal to a corresponding parameter threshold.

[0092] In some possible implementations, the user equipment 101 is a user equipment in an RRC idle state.

[0093] In some possible implementations, after obtaining the first system information carrying the LP WUS configuration information, the user equipment 101 may switch to a state of monitoring the LP WUS. Based on the time-frequency resources configured in the LP WUS configuration information, the user equipment 101 may monitor the LP WUS at the corresponding time-frequency location using a low-power receiver. While monitoring the LP WUS, the primary receiver may be in a sleep state, thereby saving energy for the user equipment 101.

[0094] In the embodiment of the present disclosure, 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.

[0095] The embodiment of the present disclosure provides a method for monitoring system information, which is executed by the user equipment 101. Referring to FIG5 , FIG5 is a diagram illustrating a method for monitoring system information according to an exemplary embodiment. As shown in FIG5 , the method includes step S501, specifically:

[0096] Step S501: When a first condition is met, the user equipment 101 monitors first system information sent by the network device 102, where the first system information includes low power wake-up signal LP WUS configuration information.

[0097] In some possible implementations, the LP WUS configuration information includes one or more of time domain resources, frequency domain resources, power information, and spatial domain information for sending the LP WUS, wherein the spatial domain information may be used to indicate transceiver beam information.

[0098] In some possible implementations, the first condition includes: a higher layer of the user equipment 101 requests to monitor the LP WUS. The higher layer may be an application layer, which may send a request to the physical layer to monitor the LP WUS due to energy conservation requirements. After receiving the request from the higher layer to monitor the LP WUS, the physical layer must monitor the first system information carrying the LP WUS configuration information before monitoring the LP WUS to obtain valid LP WUS configuration information.

[0099] In some possible implementations, the first condition includes: a higher layer of the user equipment 101 determining that a channel quality measurement result is greater than or equal to a corresponding threshold. When the channel quality measurement result is good, the monitoring quality of the LP WUS is considered good, and the user equipment 101 can switch to the LP WUS monitoring state to achieve energy saving. Before switching to the LP WUS monitoring state, the user equipment 101 must monitor first system information carrying LP WUS configuration information to obtain valid LP WUS configuration information.

[0100] The user equipment 101 is a user equipment in an RRC idle state.

[0101] In some possible implementations, after obtaining the first system information carrying the LP WUS configuration information, the user equipment 101 may switch to an energy-saving state for monitoring the LP WUS. Based on the time-frequency resources configured in the LP WUS configuration information, the user equipment 101 may monitor the LP WUS at the corresponding time-frequency location using a low-power receiver. While monitoring the LP WUS, the primary receiver may be in a sleep state, thereby achieving energy conservation for the user equipment 101.

[0102] In the embodiment of the present disclosure, when certain conditions are met, the user equipment 101 monitors the first system information carrying the LP WUS configuration information sent by the network device 102, and promptly obtains the required first system information, so as to accurately monitor the LP WUS according to the valid LP WUS configuration information in the energy-saving state, thereby ensuring energy-saving effects.

[0103] 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:

[0104] Step S501 ′: when a first condition is met, the user equipment 101 monitors first system information broadcast by the network device 102 , where the first system information includes low power wake-up signal LP WUS configuration information.

[0105] In some possible implementations, the network device 102 may broadcast the first system information carrying the LP WUS configuration information according to a set period.

[0106] In some possible implementations, the first condition includes: a higher layer of the user equipment 101 has a request to monitor the LP WUS. For example, the physical layer of the user equipment 101 receives a request to monitor the LP WUS sent by a higher layer.

[0107] In some possible implementations, the first condition includes: a channel quality measurement result of the user equipment 101 is greater than or equal to a corresponding parameter threshold.

[0108] In the embodiment of the present disclosure, 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.

[0109] The embodiment of the present disclosure provides a method for monitoring system information, which is executed by the user equipment 101. Referring to FIG6 , FIG6 is a method for monitoring system information according to an exemplary embodiment. As shown in FIG6 , the method includes steps S601 to S602, specifically:

[0110] Step S601: When a first condition is met, the user equipment 101 sends a system information SI request message to the network device 102. The SI request message is used to request first system information including LP WUS configuration information.

[0111] Step S602 : The user equipment 101 monitors the first system information sent by the network device 102 .

[0112] In some possible implementations, the first condition includes: a higher layer of the user equipment 101 has a request to monitor the LP WUS.

[0113] In some possible implementations, the first condition includes: a channel quality measurement result of the user equipment 101 is greater than or equal to a corresponding parameter threshold.

[0114] In the embodiment of the present disclosure, 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.

[0115] The embodiment of the present disclosure provides a method for monitoring system information, which is performed by user equipment 101. The method includes steps S601 to S602, wherein the first condition includes: when the channel quality measurement result of user equipment 101 is greater than or equal to the corresponding parameter threshold.

[0116] The channel quality measurement result is a measurement result corresponding to the reference signal of the serving cell.

[0117] In some possible implementations, the user equipment 101 measures a reference signal (RS) of a serving cell to obtain a channel quality measurement result.

[0118] In some possible implementations, the channel quality measurement result may be represented by Reference Signal Receiving Power (RSRP).

[0119] In some possible implementations, the reference signal is a synchronization signal block SSB.

[0120] In some possible implementations, the reference signal is a channel state information reference signal CSI-RS.

[0121] In some possible implementations, the parameter threshold is defined by a protocol or configured by a network device.

[0122] In one example, a value corresponding to the parameter threshold is defined by a protocol, or a determination method is defined. For example, the parameter threshold may be related to the difference between the transmit power of the reference signal and the transmit power of the LP WUS, or the parameter threshold may be related to the sensitivity of a receiver receiving the LP WUS.

[0123] In another example, the network device 102 may configure a value corresponding to the parameter threshold for the user equipment 101. Alternatively, after determining the parameter threshold according to a protocol definition, the network device 102 sends indication information carrying the parameter threshold to the user equipment 101.

[0124] In some possible implementations, the parameter threshold is related to at least one of the following parameters:

[0125] The difference between the transmit power of the reference signal and the transmit power of the LP WUS;

[0126] The sensitivity of the receiver used to receive LP WUS.

[0127] In this implementation, the sensitivity of the low power consumption receiver of the user equipment 101 for receiving the LP WUS and the sensitivity of the main receiver can be obtained and recorded during the terminal factory test.

[0128] In this embodiment, the sensitivity of the low-power receiver is generally lower than that of the main receiver. Therefore, under the same power conditions, the coverage performance of the wake-up signal for the low-power receiver is poor.

[0129] In this embodiment, 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.

[0130] To facilitate understanding of this embodiment, a specific example is given below:

[0131] Assume that the sensitivity of the low power receiver of the user equipment 101 is -80 decibel house (dBm), which can represent the minimum receiving power of the low power receiver.

[0132] When the user equipment 101 is in the RRC idle state, it turns on the primary receiver to receive SSB or paging information.

[0133] When user equipment 101 measures the RSRP value of SSB to be -100 dBm, user equipment 101 also receives the LP WUS broadcast by network device 102, which has a power offset (transmit power difference) of +12 dBm compared to SSB. This means that the transmit power of the LP WUS is 12 dBm higher than that of the SSB. If the LP WUS is repeated four times, this corresponds to a repetition gain of 6 dB.

[0134] According to the protocol definition, the user equipment 101 estimates the receiving power of the LP WUS to be: -100+12+6=-82dBm, which is lower than the -80dBm corresponding to the low power receiver sensitivity. Therefore, the user equipment 101 can determine that the low power receiver does not need to be turned on yet.

[0135] When the user equipment 101 measures the RSRP value of the SSB to be -95 dBm, the difference between the SSB transmit power and the LP WUS transmit power is still +12 dBm, and the repetition gain is still 6 dB.

[0136] According to the protocol definition, the user equipment 101 estimates the receiving power of the LP WUS to be: -95+12+6=-77dBm, which reaches the low power receiver sensitivity of -80dBm. Therefore, the user equipment 101 can turn on the low power receiver.
