Description

Technical Field

[0002] In a DRX (Discontinuous Reception) scenario, the terminal monitors a PDCCH (Physical Downlink Control Channel) during an activation period of the DRX corresponding to the terminal, thereby achieving the purpose of reducing power consumption.

[0003] In the idle state, additional reference symbols are used to assist the terminal in information acquisition and time-frequency domain synchronization.

[0097] In order to better describe any embodiment of the present disclosure, an embodiment of the present disclosure is illustratively described by taking an application scenario of access control as an example.

[0098] Please refer to Figure 1 , which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of terminals 11 and a plurality of base stations 12 .

[0099] Among them, the terminal 11 can be a device that provides voice and / or data connectivity to the user. The terminal 11 can communicate with one or more core networks via a radio access network (RAN). The terminal 11 can be an Internet of Things terminal, such as a sensor device, a mobile phone (or a "cellular" phone), and a computer with an Internet of Things terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-built-in or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user terminal (user equipment, terminal). Alternatively, the terminal 11 can also be a device of an unmanned aerial vehicle. Alternatively, the terminal 11 can also be a vehicle-mounted device, for example, it can be a driving computer with wireless communication function, or a wireless terminal connected to an external driving computer. Alternatively, the terminal 11 may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with a wireless communication function.

[0100] The base station 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be referred to as NG-RAN (New Generation-Radio Access Network).

[0101] Among them, the base station 12 can be an evolved base station (eNB) adopted in the 4G system. Alternatively, the base station 12 can also be a base station (gNB) adopting a centralized distributed architecture in the 5G system. When the base station 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (Physical, PHY) layer protocol stack. The specific implementation method of the base station 12 is not limited in the embodiment of the present disclosure.

[0102] A wireless connection can be established between the base station 12 and the terminal 11 through a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0104] In some embodiments, the wireless communication system may further include a network management device 13 .

[0105] Several base stations 12 are respectively connected to a network management device 13. The network management device 13 may be a core network device in a wireless communication system. For example, the network management device 13 may be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device may be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0106] like Figure 2 As shown, an embodiment of the present disclosure provides a method for determining a power saving signal, the method being applied to a terminal, comprising:

[0107] Step S101: Send first auxiliary information to the terminal when supporting the use of additional reference symbols; wherein the first auxiliary information is used to determine a first power saving signal supported by the terminal, and the first power saving signal is used by the terminal to monitor a paging message.

[0108] The terminal may send first auxiliary information to a network device (such as a base station), and the first auxiliary information may be used by the network device to configure a power saving signal for the terminal. For example, the first auxiliary information sent by the terminal may include the range of power saving signals supported by the terminal, or the value of the location of the supported power saving signal, etc. In this way, the network device may configure the corresponding power saving signal according to the first auxiliary information.

[0109] In an embodiment of the present disclosure, the first auxiliary information is auxiliary information used to inform a network device of a power saving signal supported by the terminal when the terminal supports the use of additional reference symbols. When the terminal supports the use of additional reference symbols, the additional reference symbols can be used to assist in acquiring channel state information or time-frequency domain synchronization of the network and to assist in RRM (Radio Resource Management) measurements, etc. When using additional reference symbols for time-frequency domain synchronization, the configuration position of the additional reference symbols is closer to the PO than SSB synchronization, so the terminal can wake up later. Therefore, when the terminal supports the use of additional reference symbols, there may be differences in the power saving signals supported when the terminal does not support the use of additional reference symbols.

[0110] Therefore, in the embodiment of the present disclosure, the terminal sends the first auxiliary information of the power saving signal supported by itself when it supports the use of additional reference symbols, to distinguish it from the case where it does not support the use of additional reference symbols, thereby facilitating the network device to configure the power saving signal of the terminal accordingly, so that the terminal can monitor the power saving signal in conjunction with the additional reference symbols, thereby saving more power.

[0111] In some embodiments, the first power saving signal is further used for the terminal to monitor the paging message in an inactive state and / or an idle state.

[0112] In the disclosed embodiment, the first power saving signal is used to enable the terminal to determine whether and when to monitor paging in an idle state and an inactive state. For example, the terminal detects the first power saving signal, and if the first power saving signal is detected, the terminal monitors the paging message in the next monitoring cycle; if the first power saving signal is not detected, the terminal skips the next monitoring cycle and does not monitor the paging message.

[0113] For another example, if the terminal detects a power saving signal, it monitors paging messages in the next N monitoring cycles. If the first power saving signal is not detected before the N+1th paging cycle, it skips the paging cycle and does not monitor paging messages.

[0114] In this way, the terminal can selectively monitor paging based on the first power saving signal, thereby reducing unnecessary monitoring and further achieving the purpose of reducing power consumption.

[0115] In some embodiments, the additional reference symbol is used to assist the terminal in performing time-frequency domain synchronization with the network device, and the additional reference symbol includes at least one of the following:

[0116] TRS and CSI-RS.

[0117] In the embodiment of the present disclosure, the additional reference symbols supported by the terminal include CSI-RS, which is mainly used to obtain downlink channel state information, beam management, time-frequency tracking, mobility management, rate matching, etc.

[0118] The additional reference symbols may also include TRS, which is also a type of CSI-RS and is used for tracking in the time-frequency domain and compensating for time offset and frequency offset, etc.

[0119] Therefore, the terminal can use the additional reference symbols to assist in time and frequency domain synchronization with the network.

[0120] like Figure 3 As shown, an embodiment of the present disclosure provides a method for determining a power saving signal, the method being applied to a terminal, comprising:

[0121] Step S201: Sending second auxiliary information to the terminal when the terminal does not support the use of the additional reference symbol, where the second auxiliary information is used to determine a second power saving signal.

[0122] In the embodiments of the present disclosure, the terminal may also not support the use of the additional reference symbols involved in the above embodiments. In the case where the use of additional reference symbols is not supported, the ability of the terminal to support power saving signals may also be different from the case where the additional reference symbols are supported. Therefore, the terminal may report to the network device the second auxiliary information of the second power saving signal supported by the terminal when the use of additional reference symbols is not supported.

[0123] In one embodiment, the terminal can separately report the first auxiliary information when additional reference symbols are supported and the second auxiliary information when additional reference symbols are not supported, so that the network device configures the configuration information of the power-saving signal for the terminal in two cases, which is convenient for the terminal to monitor the power-saving signal with different parameters in different cases, thereby improving the application scenarios and scope of the power-saving signal.

[0124] In some embodiments, sending the first auxiliary information includes: sending capability reporting information to a network device, the capability reporting information including the first auxiliary information;

[0125] Sending the second auxiliary information includes: sending capability reporting information to a network device, where the capability reporting information includes the second auxiliary information.

[0126] In the disclosed embodiment, the terminal may report the auxiliary information when reporting its own capability, that is, use the capability reporting information to send the first auxiliary information and / or the second auxiliary information. For example, the auxiliary information is carried in the terminal capability of UE-RadioPagingInfo (terminal paging information) and reported to the base station.

[0127] In this way, the terminal does not need additional signaling, and can use existing reporting information to carry and send the auxiliary information to network devices such as base stations.

[0128] like Figure 4 As shown, an embodiment of the present disclosure provides a method for determining a power saving signal, the method being applied to a terminal, comprising:

[0129] Step S301: Receive configuration information sent by a network device according to the first auxiliary information and / or the second auxiliary information, wherein the configuration information includes an offset value of a power saving signal relative to a paging occasion PO.

[0130] Here, the configuration information is used to configure the power saving signal. The terminal can determine how to wake up the terminal according to the power saving signal and monitor the paging message according to the configuration of the configuration information.

[0131] For example, if the configuration information of the power-saving signal received by the terminal configures the offset value between the position of the power-saving signal and the PO, the terminal can determine the position of the power-saving signal according to the configuration information and the position of the PO. In this way, the terminal can wake up according to the position of the power-saving signal and monitor the power-saving signal. If the power-saving signal is monitored, the paging message can be further received. If the configuration information does not configure the power-saving signal in some paging cycles, the terminal may not wake up, thereby skipping the monitoring of the paging message. In this way, the terminal can reduce unnecessary paging monitoring, thereby achieving the purpose of reducing power consumption.

[0132] In some embodiments, the configuration information is read by the terminal from broadcast signaling of a network device, or

[0133] The configuration information is read by the terminal from a dedicated signaling dedicated to carrying the configuration information.

[0134] The above configuration information may be sent to the terminal by the broadcast signaling of the base station, or may be sent to the terminal by the dedicated signaling of the base station. For example, the base station carries the above first configuration information and the second configuration information in the same broadcast signaling and sends them to the terminal, or carries them in different broadcast signalings and sends them to the terminal in sequence. For another example, the base station carries the first configuration information in the broadcast signaling and sends it to the terminal, and carries the second configuration information in the dedicated signaling and sends it to the terminal. For another example, the base station carries the first configuration information and the second configuration information in different dedicated signalings and sends them to the terminal in sequence, and so on.

[0135] Of course, in addition to this, the first configuration information and the second configuration information may also be agreed upon by a protocol, or the protocol may be used to agree on how the network device sends the information to the terminal.

[0136] In some embodiments, the configuration information includes:

[0137] first configuration information of the first power saving signal and / or second configuration information of the second power saving signal.

[0138] In an embodiment of the present disclosure, the above-mentioned configuration information may be the first configuration information for configuring the first power saving signal and / or the second configuration information for configuring the second power saving signal carried in the same message; or it may be the first configuration information for separately configuring the first power saving signal carried in a separate message, and / or the second configuration information for separately configuring the second power saving signal carried in a separate message.

[0139] In the embodiment of the present disclosure, different auxiliary information (i.e., the first auxiliary information and the second auxiliary information) may be provided for the two situations where the terminal supports the use of additional reference symbols and does not support the use of additional reference symbols, thereby obtaining different configuration information, i.e., the first configuration information for the first power saving signal and the second configuration information for the second power saving signal.

[0140] Therefore, the terminal can obtain the configuration information corresponding to the network device. The network device can carry the first configuration information and the second configuration information in the same message and send it to the terminal, or send the first configuration information and the second configuration information to the terminal in separate messages. The terminal can obtain the first configuration information and the second configuration information respectively through the received messages, and monitor the corresponding power saving signal according to different configuration information in different usage situations of the additional reference symbol.

[0141] In some embodiments, the method further comprises:

[0142] determining, according to the first configuration information, location information of the first power saving signal; and / or

[0143] determining, according to the second configuration information, location information of the second power saving signal;

[0144] The paging message is monitored according to the location information of the first power saving signal and / or the location information of the second power saving signal.

[0145] Here, the location information of the power saving signal in different situations may be determined according to the first configuration information and the second configuration information.

[0146] For example, if the configuration information of the power-saving signal received by the terminal configures the offset value between the position of the power-saving signal and the PO, the terminal can determine the position of the power-saving signal according to the configuration information and the position of the PO. In this way, the terminal can wake up according to the position of the power-saving signal and monitor the power-saving signal. If the power-saving signal is monitored, the paging message can be further received. If the configuration information does not configure the power-saving signal in some paging cycles, the terminal may not wake up, thereby skipping the monitoring of the paging message. In this way, the terminal can reduce unnecessary paging monitoring, thereby achieving the purpose of reducing power consumption.

[0147] In some embodiments, determining the location information of the first power saving signal according to the first configuration information includes:

[0148] In response to receiving the first configuration information, determining that the first power saving signal is effective;

[0149] In response to the first power saving signal being effective, the location information of the first power saving signal is determined according to the first configuration information.

[0150] In the embodiment of the present disclosure, the terminal may immediately apply the first configuration information of the first power saving signal upon receiving the first configuration information of the first power saving signal, that is, upon receiving the first configuration information, the terminal assumes that the first power saving signal corresponding to the configuration information is effective.

[0151] Therefore, if the terminal receives the first configuration information for configuring the first power saving signal, the first power saving signal takes effect. At this time, the terminal can determine the location information of the first power saving signal according to the first configuration information, and then monitor the paging message according to the first power saving signal.

[0152] Of course, if the terminal receives the configuration information of the second power saving signal, the second power saving signal takes effect, and the terminal can monitor the paging message according to the second power saving signal. In one embodiment, if the terminal receives the first configuration information of the first power saving signal and also receives the second configuration information of the second power saving signal, since the first power saving signal is a corresponding power saving signal when the terminal supports additional reference symbols, it has better power saving performance, and at this time the terminal supports additional reference symbols, therefore, the terminal can consider that the first power saving signal takes effect and give priority to monitoring the paging according to the first power saving signal.

[0153] In some embodiments, determining the location information of the first power saving signal according to the first configuration information includes:

[0154] In response to receiving a notification message notifying that the first power saving signal is effective, determining that the first power saving signal is effective;

[0155] In response to the first power saving signal being effective, the location information of the first power saving signal is determined according to the first configuration information.

[0156] In the disclosed embodiment, if the terminal receives the first configuration information of the first power saving signal, it may not immediately monitor the power saving signal according to the first configuration information, but continue to monitor using the second configuration information of the second power saving signal (i.e., the case where additional reference symbols are not supported). The effectiveness of the first power saving signal is determined based on the notification message sent by the network device. In other words, when the terminal receives the notification message that the first power saving signal is effective, it confirms that the first power saving signal is effective, and then determines the location information of the first power saving signal according to the corresponding configuration information, and monitors the paging message based on the first power saving signal.

[0157] In some embodiments, the method further comprises:

[0158] In response to the first power saving signal not being effective, the method returns to determining the position information of the second power saving signal according to the offset value corresponding to the second configuration information.

[0159] In the disclosed embodiment, the terminal may have acquired the first configuration information of the first power saving signal and the second configuration information of the second power saving signal, or may not have acquired the first configuration information (e.g., only acquired the second configuration information corresponding to the case where the additional reference symbol is not supported). If the first power saving signal is not effective, that is, no notification message indicating that the first power saving signal is effective is received, for example, the terminal currently does not support the use of additional reference symbols. At this time, the terminal cannot monitor according to the location information of the first power saving signal, and therefore falls back to the offset value corresponding to the second configuration information to determine the location information of the power saving signal.

[0160] like Figure 5 As shown, an embodiment of the present disclosure provides a method for determining a power saving signal, the method being applied to a terminal, comprising:

[0161] Step S401, receiving instruction information of a network device;

[0162] Step S402: According to the indication information, send the first auxiliary information of the terminal to the network device in the case where the terminal supports the use of additional reference symbols.

[0163] The terminal may send the first auxiliary information to the network device based on the instruction of the network device. For example, the base station instructs the terminal to report the first auxiliary information, and the terminal reports the first auxiliary information corresponding to the case of supporting the use of additional reference symbols based on the capability status of the terminal. Exemplarily, the network device may instruct the terminal to report the corresponding auxiliary information in other cases when instructing the terminal to support the use of additional reference symbols. For example, when the terminal does not support the use of additional reference symbols, the network device instructs the terminal to report the auxiliary information corresponding to the case of supporting and / or not supporting the use of additional reference symbols.

[0164] In other embodiments, the terminal may also report the first auxiliary information according to the rules agreed upon in the protocol without the instruction of the network device. In addition, the terminal may also report the second auxiliary information based on the instruction of the network device. That is, the terminal needs to determine whether the network device supports the feature of configuration based on auxiliary information, and therefore reports the auxiliary information based on the instruction of the network device.

[0165] In some embodiments, the receiving the indication information of the network device includes at least one of the following:

[0166] Receiving broadcast signaling sent by a network device, and obtaining the indication information from the broadcast signaling;

[0167] Receive dedicated signaling sent by a network device and dedicated to carrying the indication information, and obtain the indication information from the dedicated signaling.

[0168] In the embodiment of the present disclosure, the above indication information can be carried in broadcast signaling or in dedicated signaling, and the dedicated signaling is a signaling specifically used to carry the indication information and sent to the terminal. When receiving the above broadcast signaling or dedicated signaling, the terminal can read the indication information carried therein and report the first auxiliary information based on the indication information.

[0169] In some embodiments, in response to the indication information being used to indicate that the terminal supports additional reference symbols, the terminal sends the first auxiliary information when the terminal supports the use of additional reference symbols according to the indication information.

[0170] The above indication information may be information for indicating that the terminal supports additional reference symbols. If the terminal receives the indication information, it determines that the corresponding first auxiliary information needs to be reported. In other words, the above indication information does not need to carry a field that explicitly instructs the terminal to report the first auxiliary information, but implicitly instructs the terminal to report. If the terminal confirms that it supports additional reference symbols according to the indication information, it reports the first auxiliary information accordingly.

[0171] In some embodiments, in response to the indication information being used to indicate that the terminal supports additional reference symbols and supports the use of the power saving signal, the terminal sends the first auxiliary information when the terminal supports the use of additional reference symbols according to the indication information.

[0172] In the embodiment of the present disclosure, the above indication information can also be used to indicate that the terminal supports the use of additional reference symbols and supports the use of power saving signals. The terminal can then determine to use additional reference symbols to assist synchronization based on the indication information, and can use power saving signals to monitor paging.

[0173] At this time, the terminal can report the first auxiliary information corresponding to the case of supporting the use of additional reference symbols without obtaining an explicit instruction to report the auxiliary information. In other words, the instruction information here implicitly indicates that the terminal reports the first auxiliary information. Therefore, the terminal does not need to receive additional information for indicating the reporting of the first auxiliary information.

[0174] like Figure 6 As shown, an embodiment of the present disclosure provides a method for determining a power saving signal, the method being applied to a network device, comprising:

[0175] Step S501: Receive first auxiliary information of a terminal when supporting the use of additional reference symbols; wherein the first auxiliary information is used to determine a first power saving signal supported by the terminal, and the first power saving signal is used by the terminal to monitor a paging message.

[0176] In an embodiment of the present disclosure, a network device (such as a base station) may receive the first auxiliary information sent by a terminal, and configure a power saving signal for the terminal according to the first auxiliary information. For example, the first auxiliary information sent by the terminal may include a range of power saving signals supported by the terminal, or a value of a location where a supported power saving signal is located, etc. In this way, the network device may configure a corresponding power saving signal according to the first auxiliary information.

[0177] In an embodiment of the present disclosure, the first auxiliary information is auxiliary information used to inform a network device of a power saving signal supported by the terminal when the terminal supports the use of additional reference symbols. When the terminal supports the use of additional reference symbols, the additional reference symbols can be used to assist in acquiring channel state information or time-frequency domain synchronization of the network and assist in RRM measurement, etc. When using additional reference symbols for time-frequency domain synchronization, the configuration position of the additional reference symbols is closer to the PO compared to SSB synchronization, so the terminal can wake up later. Therefore, when the terminal supports the use of additional reference symbols, there may be a difference in the power saving signal supported when the terminal does not support the use of additional reference symbols.

[0178] Therefore, in the embodiment of the present disclosure, the network device receives the first auxiliary information of the power saving signal supported by the terminal when the use of additional reference symbols is supported, and distinguishes it from the case where the use of additional reference symbols is not supported, thereby facilitating the corresponding configuration of the power saving signal of the terminal, so that the terminal can monitor the power saving signal in conjunction with the additional reference symbols, thereby saving more power.

[0179] In some embodiments, the first power saving signal is further used for the terminal to monitor a paging message in an inactive state and / or an idle state.

[0180] In the disclosed embodiment, the first power saving signal is used to enable the terminal to determine whether and when to monitor paging in an idle state and an inactive state. For example, the terminal detects the first power saving signal, and if the first power saving signal is detected, the terminal monitors the paging message in the next monitoring cycle; if the first power saving signal is not detected, the terminal skips the next monitoring cycle and does not monitor the paging message.

[0181] For another example, if the terminal detects a power saving signal, it monitors paging messages in the next N monitoring cycles. If the first power saving signal is not detected before the N+1th paging cycle, it skips the paging cycle and does not monitor paging messages.

[0182] In this way, the terminal can selectively monitor paging based on the first power saving signal, thereby reducing unnecessary monitoring and further achieving the purpose of reducing power consumption.

[0183] In some embodiments, the additional reference symbol is used for time-frequency domain synchronization between the terminal and the network device; the additional reference symbol includes at least one of the following:

[0184] TRS; and

[0185] CSI-RS.

[0186] In the embodiment of the present disclosure, the additional reference symbols supported by the terminal include CSI-RS, which is mainly used to obtain downlink channel state information, beam management, time-frequency tracking, mobility management, rate matching, etc.

[0187] The additional reference symbols may also include TRS, which is also a type of CSI-RS and is used for tracking in the time-frequency domain and compensating for time offset and frequency offset, etc.

[0188] Therefore, the terminal can use the additional reference symbols to assist in time and frequency domain synchronization with the network.

[0189] In some embodiments, the method further comprises:

[0190] Second auxiliary information is received when the terminal does not support the use of additional reference symbols; wherein the second auxiliary information is used to determine a second power saving signal.

[0191] In the embodiment of the present disclosure, the terminal may not support the use of the additional reference symbols involved in the above embodiment. In the case where the use of the additional reference symbols is not supported, the ability of the terminal to support the power saving signal may also be different from the case where the additional reference symbols are supported. Therefore, the network device can obtain the second auxiliary information of the second power saving signal supported by the terminal when the use of the additional reference symbols is not supported.

[0192] In one embodiment, the network device can respectively receive the first auxiliary information when the terminal supports additional reference symbols and the second auxiliary information when the terminal does not support additional reference symbols, thereby facilitating the terminal to configure the configuration information for the power saving signal in the two cases, thereby enabling the terminal to monitor the power saving signal with different parameters in different cases, thereby improving the application scenarios and scope of the power saving signal.

[0193] In some embodiments, the method further comprises:

[0194] Configuration information is sent according to the first auxiliary information and / or the second auxiliary information, wherein the configuration information includes an offset value of a power saving signal relative to PO.

[0195] Here, the configuration information is used to configure the power saving signal. The network device sends the configuration information to the terminal based on the auxiliary information provided by the terminal, so that the terminal can determine how to wake up the terminal according to the power saving signal and monitor the paging message according to the configuration of the configuration information.

[0196] For example, if the configuration information configures the offset value between the position of the power-saving signal and the PO, the terminal can determine the position of the power-saving signal according to the configuration information and the position of the PO. In this way, the terminal can wake up according to the position of the power-saving signal and monitor the power-saving signal. If the power-saving signal is monitored, the terminal can further receive the paging message. If the configuration information does not configure the power-saving signal in some paging cycles, the terminal may not wake up, thereby skipping the monitoring of the paging message. In this way, the terminal can reduce unnecessary paging monitoring, thereby achieving the purpose of reducing power consumption.

[0197] In some embodiments, sending configuration information according to the first auxiliary information and / or the second auxiliary information includes:

[0198] Sending the configuration information through broadcast signaling according to the first auxiliary information and / or the second auxiliary information; or

[0199] The configuration information is sent according to the first auxiliary information and / or the second auxiliary information through dedicated signaling dedicated to carrying the configuration information.

[0200] The above configuration information may be sent to the terminal by the broadcast signaling of the base station, or may be sent to the terminal by the dedicated signaling of the base station. For example, the base station carries the above first configuration information and the second configuration information in the same broadcast signaling and sends them to the terminal, or carries them in different broadcast signalings and sends them to the terminal in sequence. For another example, the base station carries the first configuration information in the broadcast signaling and sends it to the terminal, and carries the second configuration information in the dedicated signaling and sends it to the terminal. For another example, the base station carries the first configuration information and the second configuration information in different dedicated signalings and sends them to the terminal in sequence, and so on.

[0201] Of course, in addition to this, the first configuration information and the second configuration information may also be agreed upon by a protocol, or the protocol may be used to agree on how the network device sends the information to the terminal.

[0202] In some embodiments, the configuration information includes:

[0203] first configuration information of the first power saving signal and / or second configuration information of the second power saving signal.

[0204] In the embodiment of the present disclosure, the network device may send to the terminal a same message carrying first configuration information for synchronously configuring the first power saving signal and second configuration information for the second power saving signal; or

[0205] A message carrying first configuration information for configuring the first power saving signal alone is sent to the terminal, and / or a message carrying second configuration information for configuring the second power saving signal alone is sent to the terminal.

[0206] In the embodiment of the present disclosure, different auxiliary information (i.e., the first auxiliary information and the second auxiliary information) may be provided for the two cases where the terminal supports the use of additional reference symbols and does not support the use of additional reference symbols. Therefore, the network device may provide different configuration information for the terminal, i.e., the first configuration information for the first power saving signal and the second configuration information for the second power saving signal.

[0207] The network device may carry the first configuration information and the second configuration information in the same message and send it to the terminal, or may send the first configuration information and the second configuration information to the terminal in separate messages. The terminal may obtain the first configuration information and the second configuration information through the received messages, and monitor the corresponding power saving signal according to different configuration information in different usage situations of the additional reference symbol.

[0208] In some embodiments, the method further comprises:

[0209] In response to the configuration information at least including the first configuration information, there is no need to send a notification message to the terminal notifying that the first power saving signal is effective; that is, after the configuration message is sent, the effectiveness of the configuration is implicit; there is no need to notify the effectiveness by explicit signaling; and / or

[0210] In response to the configuration information at least including the first configuration information, sending a notification message to the terminal to notify that the first power saving signal is effective; and / or

[0211] In response to the configuration information at least including the first configuration information, a notification message is sent to the terminal to notify that the additional reference symbol is in an available state, wherein the notification message to notify that the additional reference symbol is in an available state implicitly indicates that the first power saving signal is effective.

[0212] In the disclosed embodiment, if the terminal receives the first configuration information of the first power saving signal, it may not immediately monitor the power saving signal according to the first configuration information, but continue to monitor using the second configuration information of the second power saving signal (i.e., the case where the additional reference symbol is not supported). The network device informs the terminal that the first power saving signal is effective by sending a notification message. At this time, the terminal can determine the location information of the first power saving signal according to the corresponding configuration information, and monitor the paging message based on the first power saving signal.

[0213] In the embodiment of the present disclosure, the notification message can directly inform the terminal that the first power saving signal is effective through explicit information, for example, the notification message is effective when the field value is 1. In addition, the notification message can also be a message for notifying the terminal that the additional reference symbol is in an available state, rather than a message directly notifying the terminal that the first power saving signal is effective, but the message implicitly informs the terminal that the first power saving signal is effective. Therefore, if the terminal receives a message that the additional reference symbol is in an available state, it can determine that the first power saving signal is effective.

[0214] In another embodiment, when the network device sends configuration information to the terminal and the configuration information includes the first configuration information, the first power saving signal configured by the first configuration information may be implicitly effective without sending a separate message notifying the effectiveness. At this time, the terminal receives the configuration information and can monitor the power saving signal according to the first configuration information.

[0215] In some embodiments, in response to the configuration information including at least the first configuration information, sending a notification message to the terminal to notify that the first power saving signal is effective includes:

[0216] In response to the configuration information at least including the first configuration information, a notification message is sent to the terminal to notify that the additional reference symbol is in an available state, and a notification message is sent to the terminal to notify that the first power saving signal is effective.

[0217] Exemplarily, the network device may send a notification message to the terminal to notify that the first power saving signal is effective after sending a notification message to notify that the additional reference symbol is in an available state; or, the network device may send a notification message to the terminal to notify that the first power saving signal is effective while sending a notification message to notify that the additional reference symbol is in an available state. For example, the two notification messages may be carried in the same signaling and sent to the terminal, or the two notification messages may be carried in different signaling and sent to the terminal.

[0218] In some embodiments, the method further comprises:

[0219] Sending indication information to the terminal; wherein the indication information is used to instruct the terminal to send the first auxiliary information.

[0220] In an embodiment of the present disclosure, the network device may instruct the terminal to report the first auxiliary information through the indication information. For example, the network device instructs the terminal to report the first auxiliary information, and the terminal reports the first auxiliary information corresponding to the case where the use of the additional reference symbol is supported based on the capability status of the terminal. Exemplarily, the network device may instruct the terminal to report the corresponding auxiliary information in other cases when instructing the terminal to support the use of the additional reference symbol.

[0221] In other embodiments, the terminal may also report the first auxiliary information according to the rules agreed upon in the protocol without the instruction of the network device. In addition, the terminal may also report the second auxiliary information based on the instruction of the network device.

[0222] In some embodiments, the sending of indication information to the terminal includes at least one of the following:

[0223] Sending a broadcast signaling carrying the indication information to the terminal; and

[0224] Sending a dedicated signaling carrying the indication information to the terminal.

[0225] In the embodiment of the present disclosure, the above indication information may be carried in broadcast signaling or in dedicated signaling, and the dedicated signaling is a signaling specifically used to carry the indication information and sent to the terminal. The terminal may read the indication information carried therein when receiving the above broadcast signaling or dedicated signaling, and report the first auxiliary information based on the indication information.

[0226] In some embodiments, in response to the indication information being used to indicate that the terminal supports additional reference symbols, the indication information is used to implicitly indicate that the terminal can send the first auxiliary information.

[0227] The above-mentioned indication information may be information for indicating that the terminal supports additional reference symbols, which does not need to include content that explicitly indicates that the terminal sends the first auxiliary information, but implicitly indicates that the terminal sends the first auxiliary information. Therefore, if the terminal receives the indication information, the corresponding first auxiliary information may be reported. If the terminal does not receive the indication information, it will not report it.

[0228] In some embodiments, in response to the indication information being used to indicate that the terminal supports additional reference symbols and supports the use of the power saving signal, the indication information is used to implicitly indicate that the terminal can send the first auxiliary information.

[0229] The above-mentioned indication information may be information for indicating that the terminal supports additional reference symbols and for indicating that the terminal supports the use of power saving signals, which does not need to include content that explicitly indicates that the terminal sends the first auxiliary information, but implicitly indicates that the terminal sends the first auxiliary information. Therefore, if the terminal receives the indication information, the corresponding first auxiliary information may be reported. If the terminal does not receive the indication information, it will not report it.

[0230] In some embodiments, the method further comprises:

[0231] When the terminal is released, the first auxiliary information is carried in a terminal release message and sent to a core network device; and / or

[0232] Sending the first auxiliary information to the core network device by carrying it in a terminal capability information notification message;

[0233] The core network device is used to carry the first auxiliary information in a paging message and send it to the network device.

[0234] Here, the base station can report the first auxiliary information reported by the terminal to the core network, and the core network device determines the configuration information of the corresponding terminal. When the terminal is released, the base station can report the auxiliary information to the core network device using the terminal release message, or carry the auxiliary information in the terminal capability information notification message and report it to the core network device.

[0235] When the core network device receives the auxiliary information, it can carry the auxiliary information in the paging message and send it to the corresponding network device, which can be a base station in the RAN or other equipment, so that during the paging process, the corresponding base station in the RAN can configure the corresponding configuration information for the terminal to be paged based on the auxiliary information in the paging message.

[0236] The present disclosure also provides the following examples:

[0237] A power-saving signal is introduced in the power-saving project of 5G NR, among which WUS (Wake-Up Signal) is a low-power detection signal. If the UE detects the WUS signal, it means that it is necessary to monitor the PDCCH. If the WUS is not detected, the PDCCH monitoring is skipped. In the scenario of configuring DRX, the WUS signal can be configured before the DRX onduration. If the UE does not detect the WUS signal, the entire duration needs to be skipped. Among them, the frequency of skipping the duration of the power-saving signal WUS can be 1 or an integer greater than 1, that is, one power-saving signal corresponds to one or more DRX cycles.

[0238] In narrowband communications, only the application of power-saving signals in the idle state may be considered. At this time, the auxiliary information of the UE's support for power-saving signals is reported to the base station through the UE capability (UE-RadioPagingInfo) in the connected state, and then the base station notifies the core network device through the UE capability information notification (UE capacity info notification) message sent to the core network device. Afterwards, the core network device will add the auxiliary information of the UE's support for power-saving signals (UE Radio Capability for Paging) in the paging message sent to the RAN, which includes the UE capability (UE-RadioPagingInfo). The base station uses this capability information to configure the offset value between the power-saving signal and the PO.

[0239] On this basis, if power saving in idle / inactive state needs to be considered, the WUS signal can also be configured before the PO. In this case, the gap between the WUS signal and the PO needs to meet the requirements of the terminal and the network for AGC and time-frequency domain resource synchronization.

[0240] like Figure 7 As shown in the figure, the terminal device takes into account both low power consumption and services with certain requirements on latency. In each eDRX cycle, the terminal can receive downlink data only within the set paging time window (PTW). The terminal is in sleep mode during the rest of the time and does not receive downlink data. This mode can achieve a balance between downlink service latency and power consumption, such as remotely shutting down gas services.

[0241] In each eDRX cycle, there is a paging time window PTW (Paging Time Window). In the PTW, the terminal monitors the paging channel according to the DRX cycle (the DRX cycle is short, so it can be considered that the terminal is not dormant and is always reachable) to receive downlink data. The terminal is in dormant state for the rest of the time.

[0242] The eDRX mode assumes that the terminal device is reachable at any time, but the latency is relatively large. The latency depends on the eDRX cycle configuration, which can strike a balance between low power consumption and latency.

[0243] In the power saving project, the idle state can use additional TRS / CRS to assist users in acquiring time and frequency domain synchronization with the network. Compared with the original SSB synchronization, the TRS / CRS configuration can be configured closer to the PO moment, while the original SSB is far away from the PO position, so the user needs to wake up a long time in advance and synchronize with the SSB. After using the additional TRS / CRS, you can wake up later, so it can save more power. The disclosed embodiment is based on the configuration method of the power saving signal after the idle state TRS / CSI-RS characteristics are introduced.

[0244] In the embodiment of the present disclosure, the terminal reports auxiliary information for power saving signal support when additional reference symbols are introduced, wherein the additional reference symbols may include TRS or CSI-RS, etc., for assisting the terminal in synchronization and assisting RRS measurement, etc.

[0245] The terminal reports the use of a power saving signal when in an inactive state and / or an idle state. The start and end time configuration of the power saving signal may be an offset value relative to a reference point, such as an offset value relative to a paging occasion PO. The offset value may be closely related to the implementation of the UE.

[0246] In some embodiments, the auxiliary information of the terminal supporting the power saving signal when reporting the additional reference symbol introduction may include: reporting respectively for the case where the additional reference symbol is supported and for the case where the additional reference symbol is not supported.

[0247] Exemplarily, the terminal may use the same signaling to report the capability of supporting power saving signals in both cases of supporting and not supporting additional reference symbols; or different reporting messages may be used to report the capabilities in the two different cases respectively.

[0248] In one embodiment, the terminal may carry the auxiliary information in UE capability information and report it to the base station. For example, the terminal may carry the auxiliary information in UE capability in UE-Radio PagingInfo and report it to the base station.

[0249] In some embodiments, the terminal may report auxiliary information for power saving signal support when introducing additional reference symbols based on an indication from the base station:

[0250] The base station notifies the terminal whether it supports reporting the auxiliary information supported for the power saving signal when the additional reference symbols are introduced; the notification method may be broadcast signaling or dedicated signaling.

[0251] In one embodiment, if the base station notifies the terminal that additional reference symbols are supported, it implicitly indicates that the terminal supports reporting auxiliary information supporting power saving signals when additional reference symbols are introduced.

[0252] In another embodiment, if the base station notifies the terminal that it supports additional reference symbols and supports the use of power saving signals, the terminal is implicitly notified that it supports reporting auxiliary information supporting the power saving signals when additional reference symbols are introduced.

[0253] In an embodiment of the present disclosure, the auxiliary information provided by the UE to the core network device may be carried when the UE is released, and the base station notifies the core network device through a release message sent to the core network device.

[0254] The auxiliary information provided by the UE to the core network device may also be carried in the base station and notified to the core network device through a UE capacity information notification (UE capacity info notification) message sent to the core network device.

[0255] The core network device carries the auxiliary information of the WUS used in the idle state / inactive state in the paging message sent to the RAN, and sends it to the RAN for idle state / inactive state power saving signal configuration.

[0256] In the embodiment of the present disclosure, the auxiliary information of the terminal may be carried in the inter-base station interaction message;

[0257] The interaction messages between base stations include: a UE context information response message (Retrieve UE Context Response) or a radio access network paging message (RAN Paging). Whether the UE context information response message carries the auxiliary information can be based on the new base station adding a request indication or protocol agreement to obtain the information in the UE context information response message.

[0258] As an embodiment, it can be clearly indicated by a flag, for example, flag=1 means that the information needs to be requested.

[0259] In the embodiment of the present disclosure, the base station configures the configuration information of the power saving signal when the additional reference symbol is introduced:

[0260] If the base station can configure a set of power saving signals when no additional reference symbols are introduced, such as power saving signal 1, and simultaneously send down a power saving signal configured when additional reference symbols are introduced, such as power saving signal 2.

[0261] Exemplarily, the offset value 2 configured by the base station for the power saving signal 2 is not greater than the offset value 1 configured by the base station for the power saving signal 1 .

[0262] In one embodiment, the power saving signal 2 is an optional configuration.

[0263] In the embodiment of the present disclosure, the configuration of the power saving signal 2 includes at least two methods as follows:

[0264] Method 1: The base station can configure power saving signal 2 and power saving signal 1 together to notify the user. The notification method can be broadcast signaling or dedicated signaling.

[0265] Mode 2: The base station may separately notify the user of the configuration of the power saving signal 2, and the notification method may be dedicated signaling or broadcast signaling.

[0266] In the embodiment of the present disclosure, the manner of confirming that the power saving signal 2 is effective includes at least two of the following:

[0267] Method 1: Power saving signal 2 can take effect immediately after configuration. In this case, the terminal can use it immediately after obtaining the configuration.

[0268] Method 2: The base station needs to notify that power saving signal 2 takes effect.

[0269] As an embodiment: the base station may notify the user that the power saving signal 2 is effective at the same time or after notifying the user that the reference symbol status is an availability status.

[0270] The available status of the reference user may be notified via a broadcast message, an RRC message, a DCI, or the like.

[0271] In one embodiment, notifying the reference user of the available status may imply the effectiveness of the power saving signal 2 .

[0272] In another embodiment, an explicit indication may be used to notify the terminal that the power saving signal 2 is effective. Exemplarily, the explicit indication may be carried in the same message that notifies the reference user of the available status, or may be carried in a different message.

[0273] In the embodiment of the present disclosure, the terminal monitors the configured power saving signal according to the following rules:

[0274] If the terminal detects that power saving signal 2 is effective, power saving signal 2 can be used; otherwise, power saving signal 1 is used again.

[0275] In another embodiment, the terminal may also monitor the configured power saving signal based on explicit instruction from the base station.

[0276] like Figure 8 As shown, the embodiment of the present disclosure further provides a device 800 for determining a power saving signal, including:

[0277] The sending module 801 is used to send the first auxiliary information of the device 800 when supporting the use of additional reference symbols; wherein the first auxiliary information is used to determine the first power saving signal supported by the device 800, and the first power saving signal is used for the device 800 to monitor the paging message.

[0278] In some embodiments, the first power saving signal is further used for the apparatus 800 to monitor the paging message in an inactive state and / or an idle state.

[0279] In some embodiments, the additional reference symbol is used to assist the apparatus 800 in performing time-frequency domain synchronization with a network device, and the additional reference symbol includes at least one of the following:

[0280] a phase reference signal TRS; and

[0281] Channel State Information Reference Signal CSI-RS.

[0282] In some embodiments, the sending module 801 is further used to send second auxiliary information when the apparatus 800 does not support the use of the additional reference symbol, and the second auxiliary information is used to determine a second power saving signal.

[0283] In some embodiments, the sending module 801 is further used to:

[0284] Sending capability reporting information to a network device, where the capability reporting information includes the first auxiliary information;

[0285] and / or
