Description

[0001] This application is a divisional application of a Chinese application with an application number of 202080000738.1 and filed on April 17, 2020. Technical Field

[0002] Embodiments of the present disclosure relate to the field of wireless communication, but are not limited to the field of wireless communication, and in particular, relate to an information transmission method and apparatus, a communication device, and a storage medium. Background Art

[0003] A User Equipment (UE) terminal has a Discontinuous Reception (DRX) state, and the power consumption of the terminal in this DRX state is lower than that of the terminal in the connected state.

[0004] For example, for a Narrow Band (NB) device, it can periodically sleep and wake up, and the power consumption of the narrow band device can be reduced by sleeping.

[0005] In order to further save the power consumption of a UE in the DRX state, a Wake UP Signaling (WUS) is also introduced. The WUS is sent before the wake-up period, and the terminal determines whether to maintain the wake-up state in the subsequent wake-up period by listening to the WUS to listen to the Physical Downlink Control Channel (PDCCH). Here, the WUS signal can also be called a power-saving signal.

[0006] When a base station needs to page a UE in the sleep state, it needs to obtain the configuration of the power-saving signal of the UE in order to send a paging message at the paging occasion (PO) when the UE is in the wake-up state to improve the paging success rate of the UE. However, the prerequisite for successfully paging the UE is to successfully obtain the power-saving signal configuration of the UE. However, in the related art, there are problems such as a long transmission path or a large acquisition delay in obtaining the power-saving signal configuration. Summary of the Invention

[0013] A first receiving module, configured to receive the auxiliary information of the user equipment UE from a second base station by the first base station through the interface between base stations, where the auxiliary information includes at least part of the power saving signal configuration.

[0014] The fourth aspect of the embodiments of the present disclosure provides an information transmission device, which includes:

[0015] A second sending module, configured to send the auxiliary information of the user equipment UE to the first base station through the interface between base stations, where the auxiliary information includes at least part of the power saving signal configuration.

[0016] The fifth aspect of the embodiments of the present disclosure provides a communication device, including a processor, a transceiver, a memory, and an executable program stored in the memory and capable of running on the processor. When the processor runs the executable program, it executes the method provided in the first aspect and / or the second aspect.

[0017] The sixth aspect of the embodiments of the present disclosure provides a computer storage medium, which stores an executable program; after the executable program is executed by a processor, it can implement the method provided in the first aspect and / or the second aspect.

[0018] In the technical solution provided in the embodiments of the present disclosure, the auxiliary information of the UE is interacted through the interface between base stations. At this time, the first base station does not need to request the auxiliary information of the UE from the core network, but directly receives the auxiliary information of the UE from an adjacent base station or any base station that has an interface between base stations established with this base station. Compared with requesting the auxiliary information of the UE from the core network, the transmission path length of the auxiliary information is reduced, the delay for the first base station to obtain the auxiliary information of the UE is reduced, and the number of signaling interactions and signaling overheads between the radio access network and the core network are reduced.

[0031] The network architecture and service scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art may know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0032] Please refer to Figure 2 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present application. As Figure 2 shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: several terminals 110 and several base stations 120.

[0033] Among them, the terminal 110 can be a device that provides voice and / or data connectivity to a user. The terminal 110 can communicate with one or more core networks via a Radio Access Network (RAN). The terminal 110 can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or referred to as a "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a User Equipment (UE). Or, the terminal 110 can also be a device of an unmanned aerial vehicle. Or, the terminal 110 can also be a vehicle-mounted device. For example, it can be an on-board computer with wireless communication capabilities, or a wireless communication device external to the on-board computer. Or, the terminal 110 can also be a roadside device. For example, it can be a street lamp, a signal lamp, or other roadside devices with wireless communication capabilities, etc.

[0034] The base station 120 can be a network-side device in a wireless communication system. Among them, the wireless communication system can be a 4th generation mobile communication (4G) system, also known as the Long Term Evolution (LTE) system; or, the wireless communication system can also be a 5G system, also known as the new radio (NR) system or the 5G NR system. Or, the wireless communication system can also be the next-generation system after the 5G system. Among them, the access network in the 5G system can be called the NG-RAN (New Generation - Radio Access Network, new generation wireless access network).

[0035] Among them, the base station 120 may be an evolved Node B (eNB) adopted in a 4G system. Alternatively, the base station 120 may also be a gNode B (gNB) with a centralized distributed architecture adopted in a 5G system. When the base station 120 adopts a centralized distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The protocol stacks of the Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer are set in the central unit; the Physical (PHY) layer protocol stack is set in the distributed unit. The specific implementation manner of the base station 120 in the embodiments of the present application is not limited.

[0036] A wireless connection can be established between the base station 120 and the terminal 110 through a wireless air interface. In different embodiments, 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, such as the new air interface; or, the wireless air interface may also be a wireless air interface based on the standard of the next-generation mobile communication network technology of 5G.

[0037] In some embodiments, an E2E (End to End) connection can also be established between terminals 110. For example, in vehicle-to-everything (V2X) communication, scenarios such as vehicle-to-vehicle (V2V) communication, vehicle-to-Infrastructure (V2I) communication, and vehicle-to-pedestrian (V2P) communication.

[0038] In some embodiments, the above wireless communication system may further include a network management device 130.

[0039] A plurality of base stations 120 are respectively connected to a network management device 130. Among them, the network management device 130 may be a core network device in a wireless communication system. For example, the network management device 130 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device may also 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), etc. The implementation form of the network management device 130 is not limited in the embodiments of the present application.

[0040] As Figure 2 shown, this embodiment provides an information transmission method, which includes:

[0041] S110: The first base station receives auxiliary information of a user equipment UE from the second base station through an interface between base stations. Among them, the auxiliary information includes at least part of the power saving signal configuration.

[0042] The information transmission method provided by the embodiments of the present disclosure can be applied to the first base station. The first base station may be: the base station where the UE currently camps, or the base station to which the UE is currently connected; or the target base station for UE handover.

[0043] The current state of the UE may be any one of the following: inactive state or idle state.

[0044] In some embodiments, the inactive state is mainly for the Radio Access Network (RAN). In the inactive state, no Radio Resource Control (RRC) connection is established between the UE and the base station. However, the inactive state is transparent to the core network, and the core network is unaware that there is currently no RRC connection between the UE and the base station.

[0045] The first base station receives the auxiliary information of the UE from the second base station through an interface between base stations. The interface between base stations may be a direct connection interface between two base stations. For example, the interface between base stations includes but is not limited to: the XN interface. The direct connection interface between base stations enables direct connection and intercommunication between two base stations.

[0046] The XN interface includes: the XN-C (control plane) interface and the XN-U (user plane) interface. In the embodiments of the present application, the first base station and the second base station may interact the auxiliary information through the XN-C interface, and / or interact the auxiliary information through the XN-U interface.

[0047] For example, the second base station stores the auxiliary information of the UE. The second base station may obtain the auxiliary information of the UE from the core network, or, the second base station receives the auxiliary information from the UE before the first base station requests the auxiliary information.

[0048] In this way, the auxiliary information of the UE is interacted through the interface between base stations. At this time, the first base station does not need to request the auxiliary information of the UE from the core network, but directly receives the auxiliary information of the UE from an adjacent base station or any base station that has an interface between base stations with this base station. The second base station here may be any base station that currently stores the auxiliary information of this UE. For example, the second base station may include: the base station where the UE previously camped; or the anchor base station.

[0049] The auxiliary information includes: some or all of the power saving signal configurations of the UE. The power saving signal configuration is: one or more configuration parameters used by the UE for the power saving signal. The power saving signal configuration is used to control the use of the power saving signal by the UE. For example, the power saving signal configuration can be used to control the behavior of the UE and / or the behavior of the base station; for example, control whether the base station sends a power saving signal, the frequency and / or power of sending the power saving signal, etc., and control whether the UE listens for the power saving signal or the frequency of listening for the power saving signal, etc.

[0050] For example, the power saving signal configuration includes but is not limited to at least one of the following:

[0051] Support configuration, used to indicate whether the UE supports the use of the power saving signal;

[0052] Time domain configuration, at least including: the starting time domain configuration for using the power saving signal.

[0053] The starting time domain configuration includes but is not limited to:

[0054] The offset of the starting time of using the power saving signal relative to the reference time point.

[0055] The reference time point includes: the starting time of the PO and / or the ending time of the PO.

[0056] In some embodiments, the time domain configuration further includes at least one of the following:

[0057] The time domain offset between two adjacent power saving signals;

[0058] The number of DRX cycles for which a single power saving signal acts;

[0059] After determining the power saving signal configuration of the UE, the first base station can, according to the power saving signal configuration, determine that the UE remains in the wake-up state during the wake-up periods within one or more DRX cycles to which the power saving signal applies. At this time, a paging message can be sent to page the UE, or a downlink transmission that needs to be received by the UE can be sent on the Physical Downlink Control Channel (PDCCH). The downlink transmission includes, but is not limited to: downlink signaling and / or downlink data.

[0060] If the UE is in the idle state, the paging message can be sent by the core network. If the UE is in the inactive state, the paging message is sent by the radio access network, where the radio access network is a network including access network elements such as base stations.

[0061] In the embodiments of the present application, the first base station can directly receive the auxiliary information from the second base station by using the interface between base stations. Compared with requesting the auxiliary information of the UE from the core network, the transmission path length of the auxiliary information is reduced, the delay for the first base station to obtain the auxiliary information of the UE is reduced, and the number of signaling interactions and signaling overheads between the radio access network and the core network are reduced.

[0062] In some embodiments, the power saving signal configuration is used to indicate at least one of the following:

[0063] Whether the UE supports the use of the power saving signal in the inactive state;

[0064] Whether the UE supports the use of the power saving signal in the idle state;

[0065] Whether the UE expects to use the power saving signal in the inactive state;

[0066] Whether the UE expects to use the power saving signal in the non-idle state;

[0067] When using the power saving signal in the inactive state, the time domain configuration of the power saving signal;

[0068] When using the power saving signal in the idle state, the time domain configuration of the power saving signal.

[0069] In some embodiments, the power saving signal configuration includes at least one of the following identifiers:

[0070] An identifier used to indicate whether the UE supports the use of the power saving signal in the inactive state;

[0071] An identifier used to indicate whether the UE supports the use of the power saving signal in the idle state;

[0072] An identifier used to indicate whether the UE expects to use the power saving signal in the inactive state;

[0073] An identifier for indicating whether the UE expects to use a power saving signal in a non-idle state;

[0074] An identifier for indicating the time domain configuration of the power saving signal when using the power saving signal in an inactive state;

[0075] An identifier for indicating the time domain configuration of the power saving signal when using the power saving signal in an idle state.

[0076] In some embodiments, the first base station has a correspondence relationship between the time domain configuration of the power saving signal when using the power saving signal in an inactive state and the identifier, so as to determine the time domain configuration of the power saving signal when using the power saving signal in an inactive state according to the received identifier of the time domain configuration of the power saving signal when using the power saving signal in an inactive state. The correspondence relationship between the time domain configuration of the power saving signal and the identifier when using the power saving signal in an inactive state can be based on protocol regulations or obtained from any other network device, such as a core network or another base station.

[0077] In some embodiments, the first base station has a correspondence relationship between the time domain configuration of the power saving signal when using the power saving signal in an idle state and the identifier, so as to determine the time domain configuration of the power saving signal when using the power saving signal in an idle state according to the received identifier of the time domain configuration of the power saving signal when using the power saving signal in an idle state. The correspondence relationship between the time domain configuration of the power saving signal and the identifier when using the power saving signal in an idle state or an inactive state can be based on protocol regulations or obtained from any other network device, such as a core network or another base station. In some embodiments, the above identifier is the power saving signal configuration itself.

[0078] For example, some UEs support the use of power saving signals in an inactive state, while some UEs do not support the use of power saving signals in an inactive state. At this time, one or more bits in the power saving signal can be used to indicate whether the use of power saving signals in an inactive state is supported.

[0079] Similarly, some UEs support the use of power saving signals in an idle state, while some UEs do not support the use of power saving signals in an idle state. At this time, one or more bits in the power saving signal can be used to indicate whether the use of power saving signals in an idle state is supported.

[0080] In some embodiments, whether the UE supports the use of power saving signals can depend on the hardware of the UE.

[0081] Some UEs support the use of power saving signals in an inactive state and / or an idle state, but the UE can give its own use of power saving signals in an idle state and / or an inactive state under the condition of minimizing power consumption and minimizing transmission delay as much as possible according to its own set load rate, data transmission volume, and / or UE type.

[0082] For example, the UE can determine whether to expect the use of the power saving signal based on the current remaining battery power. For example, if the current remaining battery power is lower than or equal to the power threshold, the power saving signal configuration indicates that it is expected to use the power saving signal in the idle state and / or the inactive state to further save power.

[0083] For another example, if the UE determines that its remaining battery power is higher than the power threshold, it is expected not to use the power saving signal in the idle state and / or the inactive state through the power saving signal configuration, thus reducing the delay of the uplink transmission and / or the downlink transmission of the UE.

[0084] The time domain configuration of the power saving signal can directly or indirectly indicate the time domain resources for using the power saving signal, the frequency of receiving and transmitting the power saving signal in the time domain, etc.

[0085] In some embodiments, the power saving signal configuration may further include: the frequency domain configuration of the power saving signal. For example, the UE receives the bandwidth part (BWP) for transmitting the power saving signal by the base station or the resource element (RE) for transmitting the power saving signal.

[0086] In still other embodiments, the power saving signal configuration may also be: power configuration. For example, the UE receives the received power configuration of the power saving signal. Some UEs have strong receiving capabilities, so the transmission power of the base station for transmitting the power saving signal can be relatively small; while some UEs have weak receiving capabilities. To ensure the received power of the UE, the base station needs to appropriately increase the transmission power of the power saving signal when transmitting the power saving signal, or achieve power accumulation through diversity gain methods such as space diversity and / or frequency diversity to reach the minimum received power defined by the received power configuration of the UE for receiving the power saving signal.

[0087] In some embodiments of the present disclosure, the power saving signal configuration may be related to the capabilities of the UE. Different types of UEs have different terminal capabilities. For example, some UEs have more antennas and stronger receiving capabilities, and have the ability of space diversity reception, so that UEs with different capabilities have power saving signal configurations adapted to them.

[0088] In some embodiments, the time domain configuration of the power saving signal includes: the starting time domain configuration of the power saving signal.

[0089] The starting time domain configuration of the power saving signal can be used to limit the starting time for the UE to use the power saving signal, for example, the starting time for the UE to receive the power saving signal sent by the base station. Assuming that the power saving signal is available for the UE to use within a time range, if the length of this time range is determined, the specific position of this time range in the time domain depends on the starting time domain configuration of the power saving signal. For example, the length of the time range can be a preset length, a length specified by the protocol, or a length negotiated between the UE and the base station.

[0090] In some embodiments, the starting time domain configuration herein may include:

[0091] Time domain resource configuration, where the starting times of different time domain resources are different. For example, the starting time domain configuration may include: the resource identifier of the time domain resource. For example, the time domain resource includes but is not limited to symbols, mini-slots, time slots, or sub-frames, etc.

[0092] In still some other embodiments, the offset of the starting time domain position of the power saving signal relative to a reference time point.

[0093] Indirectly indicate the time domain configuration of the reference signal in this way of offset.

[0094] During the communication process between the UE and the base station, some signals are sent periodically and their time domain configurations are relatively fixed. For example, the time domain configuration of the PO or the time domain configuration of the channel state information reference signal CSI-RS, etc.

[0095] In this application, the time domain configuration of the reference signal is indirectly indicated by an offset value. Compared with directly indicating the resource identifier, indicating the offset value can simplify the indication and reduce the bit overhead.

[0096] The offset herein may include: one or more time domain units, and the time domain unit may be: one or more symbols.

[0097] In one embodiment, the offset of the time domain position of the power saving signal relative to the paging occasion.

[0098] In some embodiments, the magnitude of the offset value is related to the type of the UE. If the same receiver or processor is used for a certain type of UE to receive the paging message and the power saving signal, the starting time domain configuration of the power saving signal can be closer in the time domain to the PO of the paging message; because the receiver or processor has already been woken up. In some other embodiments, if different receivers or processors are used for a certain type of UE to receive the paging message and the power saving signal, the starting time domain configuration of the power saving signal can be farther in the time domain from the PO of the paging message to ensure the successful reception of the power saving signal, so that the terminal has enough time to wake up the receiver of the power saving signal and enter the state of receiving the power saving signal. The deviation between the starting time of the power saving signal and the PO in the time domain can be reflected by the magnitude of the offset.

[0099] In some embodiments, the auxiliary information includes at least one of the following:

[0100] The paging probability of the UE;

[0101] The mobility information of the UE;

[0102] The indication information of the enhanced coverage characteristics of the UE.

[0103] The paging probability may be the frequency at which the UE is paged;

[0104] The time-domain configuration of the power-saving signal when using the power-saving signal in the inactive state;

[0105] The time-domain configuration of the power-saving signal when using the power-saving signal in the idle state.

[0106] In some embodiments, the time-domain configuration of the power-saving signal when using the power-saving signal in the inactive state is the parameter value of the time-domain configuration of the power-saving signal when using the power-saving signal in the inactive state.

[0107] In some embodiments, the time-domain configuration of the power-saving signal when using the power-saving signal in the inactive state is the parameter value of the time-domain configuration of the power-saving signal when using the power-saving signal in the idle state.

[0108] In some embodiments, the time-domain configuration of the power-saving signal when using the power-saving signal in the inactive state is a parameter for calculating the parameter value of the time-domain configuration of the power-saving signal when using the power-saving signal in the inactive state.

[0109] In some embodiments, the time-domain configuration of the power-saving signal when using the power-saving signal in the inactive state is a parameter for calculating the parameter value of the time-domain configuration of the power-saving signal when using the power-saving signal in the idle state.

[0110] The indication information of the paging probability, mobility information, and enhanced coverage characteristics is carried in the auxiliary information. In this way, when paging the UE subsequently, it is convenient to configure the density of the PO in the time domain according to the paging probability; and / or determine the paging space range according to the mobility information; and / or determine whether to use the coverage enhancement method for paging according to the enhanced coverage characteristics.

[0111] For example, for a UE in the idle state, the paging space may be the entire tracking area (TA). If it is found based on the mobility information that the moving range of the UE is smaller than the tracking area, in order to reduce the signaling overhead, the paging message may be sent only within the range where the UE often moves, rather than paging the UE within the entire TA. The range where the UE often moves may be smaller than the TA of the UE.

[0112] For another example, for a UE in the inactive state, the paging space may be the entire RAN notification area (RNA). If it is found based on the mobility information that the moving range of the UE is smaller than the notification area, in order to reduce the signaling overhead, the paging message may be sent only within the range where the UE often moves, rather than paging the UE within the entire TA. The range where the UE often moves may be smaller than the notification area of the UE.

[0113] For example, to ensure the successful reception of a paging message by a UE, enhanced coverage resources for transmitting the paging message are determined based on the enhanced coverage characteristics of the UE. The enhanced coverage resources include, but are not limited to, at least one of the following:

[0114] Time-domain resources;

[0115] Frequency-domain resources;

[0116] Spatial-domain resources.

[0117] For example, before the enhanced coverage resources are configured, the paging message can be sent on m resources. After the enhanced coverage resources are configured, the paging message for this UE will be sent on m + n resources. Both m and n here are positive integers. By configuring the enhanced coverage resources, the probability of successful paging of the UE can be increased.

[0118] In some embodiments, as Figure 3A shown, the method further includes:

[0119] S100: Sending request information to a second base station through an interface between base stations. The request information is used to request auxiliary information of the UE from the second base station. Of course, here the request information can be sent to the second base station through the interface between base stations. The second base station can return the auxiliary information to the first base station through the interface between base stations, or can also transmit it to the first base station through other means such as a backhaul link. That is, the request information sent by the interface between base stations to the second base station can be used alone. The request information is used to request auxiliary information from the second base station.

[0120] As Figure 3B shown, the S110 includes: S111;

[0121] S111: The first base station receives, through the interface between base stations, the auxiliary information sent by the second base station according to the request information.

[0122] In some embodiments, the second base station can actively send the auxiliary information to the first base station. For example, when the UE switches from the second base station to the first base station, and the second base station is the anchor base station, it will actively synchronize the auxiliary information of the UE to the target base station (i.e., the first base station). At this time, the first base station may not need to send request information to the second base station.

[0123] In certain cases, the second base station may not know which base station the first base station specifically is, or the second base station has not yet synchronized the auxiliary information of the UE to the first base station. However, if the first base station wants to know the auxiliary information of the UE, it will actively send request information to request the auxiliary information of the UE. At this time, the auxiliary information received in step S110 is the auxiliary information returned by the second base station under the trigger of the request information.

[0124] In some embodiments, the auxiliary information is sent by the second base station based on the request of the first base station; or, the auxiliary information is sent by the second base station based on protocol regulations.

[0125] In some embodiments, S100 may include:

[0126] Send a Retrieve UE Context Request carrying the request information to the second base station through an interface between base stations.

[0127] In the embodiments of the present application, the Retrieve UE Context Request. Here, the Retrieve UE Context Request is a request for a target base station to request UE context from an anchor base station when the UE moves to a new target base station. In the embodiments of the present application, the request information is carried in the Retrieve UE Context Request. For example, the request information may be indicated by one or more bits in the Retrieve UE Context Request. For example, the request information may be carried by reserved bits or reserved IEs in the UE. In the embodiments of the present application, the Retrieve UE Context Request is multiplexed to carry the request information, and there is no need to specifically configure a signaling for transmitting the request information through an interface between base stations, which can reduce the number of signaling interactions and signaling overhead between base stations.

[0128] In some embodiments, S110 may include:

[0129] The first base station receives, through an interface between base stations, a Retrieve UE Context Request Response carrying the auxiliary information from the second base station.

[0130] In some embodiments, the second base station may actively transmit the auxiliary information of the UE to the first base station through an interface between base stations, and the message for transmitting the auxiliary information may be any message that can be transmitted through an interface between base stations. In the embodiments of the present application, the auxiliary information is carried in the Retrieve UE Context Request Response. The auxiliary information may be carried by one or more new bits or reserved bits in the Retrieve UE Context Request Response. In this way, it is realized that the Retrieve UE Context Request Response that can already be transmitted through an interface between base stations is multiplexed to transmit the auxiliary information, and there is also no need to specifically configure a signaling for transmitting the auxiliary information through an interface between base stations, which can reduce the number of signaling interactions and signaling overhead between base stations.

[0131] In some embodiments, the Retrieve UE Context Request Response is returned based on the Retrieve UE Context Request of the first base station;

[0132] Or,

[0133] The Retrieve UE Context Request Response is sent by the second base station based on protocol regulations.

[0134] For example, in some cases, the second base station may send the Get UE Context Request Response without the first base station's request, so the Get UE Context Request Response may be actively sent by the second base station according to the protocol.

[0135] Of course, in some cases, if the protocol does not stipulate that the second base station needs to actively send, or the first base station sends a request to obtain the UE context before the second base station has time to send, then the request response at this time is returned based on the request to obtain the UE context.

[0136] In some embodiments, the obtain UE context request response further includes: a context of the UE;

[0137] The auxiliary information and the obtaining of UE context are located in different information units IE;

[0138] or,

[0139] The auxiliary information and the UE context are located in the same IE.

[0140] The auxiliary information and the UE context may be located in the same IE or in different IEs, which may be configured according to communication requirements.

[0141] For example, in some embodiments, the obtain UE context request response is newly added with an IE for carrying auxiliary information of the UE.

[0142] The IE is dedicated to carrying the auxiliary information. The UE context is still carried in the IE that is predetermined to carry the UE context in the Get UE Context Request Response.

[0143] In one embodiment, the IE may be called UE Radio Capability for Paging IE.

[0144] For another example, there are some reserved bits or reserved fields in the IE predetermined to carry the UE context, and the auxiliary information may also be carried in the reserved bits or reserved fields in the IE predetermined to carry the UE context.

[0145] In some embodiments, the S110 may include:

[0146] The first base station receives a radio network RAN ​​paging message carrying the auxiliary information from the second base station through an inter-base station interface.

[0147] The auxiliary information of the UE exchanged between the first base station and the second base station is not limited to the above-mentioned obtain UE context request response, but can also be a paging message.

[0148] For example, the paging message for an inactive UE is formed and sent by the base station of the RAN itself. For example, if the UE is in the inactive state, and when the base station receives a paging trigger event such as information to be sent to the UE, the base station where the UE previously camped or connected, i.e., the anchor base station, may form and broadcast the RAN paging message, and forward it to other base stations within the paging range of the notification area (RNA) or smaller than the RNA to broadcast the RAN paging message. In the embodiment of the present application, at this time, the second base station directly carries the auxiliary information in the RAN paging message. In this way, when the first base station receives the RAN paging message for paging the UE, it also receives the auxiliary information of the UE.

[0149] For example, the RAN paging message further includes: wireless paging information for paging the UE;

[0150] The wireless paging information and the auxiliary information are located in different IEs;

[0151] Or,

[0152] The wireless paging information and the auxiliary information are located in the same IE.

[0153] For example, in some embodiments, a new IE is added to the RAN paging message, and this IE is dedicated to carrying the auxiliary information. The newly added IE here is different from the existing UE Radio Capability for Paging IE for UE paging in the RAN paging message. For another example, in the UE Radio Capability for Paging IE in the RAN paging message; the UE Radio Capability for Paging IE includes a UE-Radio Paging Info IE.

[0154] There are some reserved bits or reserved fields in the UE Radio Capability for Paging IE or the UE-Radio Paging Info IE, and the auxiliary information can also be carried in the reserved bits or reserved fields in the UE-Radio Paging Info IE.

[0155] As Figure 4 shown, the present embodiment provides an information transmission method, including:

[0156] S210: Send the auxiliary information of the user equipment UE to the first base station through the interface between base stations, where the auxiliary information includes: at least part of the power saving signal configuration.

[0157] The information transmission method in the embodiments of the present application can be applied to a second base station. In the embodiments of the present application, the second base station will actively or trigger based on the request information sent by the first base station, and send auxiliary information through the interface between base stations to achieve direct connection transmission of the auxiliary information between base stations.

[0158] The auxiliary information is transmitted through the interface between base stations. The auxiliary information includes all or part of the power saving signal configuration of the UE, and the power saving signal configuration is one or more configuration parameters for controlling the UE to use the power saving signal.

[0159] In some embodiments, the power saving signal configuration is used to indicate at least one of the following:

[0160] Whether the UE supports the use of the power saving signal in the inactive state;

[0161] Whether the UE supports the use of the power saving signal in the idle state;

[0162] Whether the UE expects to use the power saving signal in the inactive state;

[0163] Whether the UE expects to use the power saving signal in the non-idle state;

[0164] When using the power saving signal in the inactive state, the time domain configuration of the power saving signal;

[0165] When using the power saving signal in the idle state, the time domain configuration of the power saving signal.

[0166] In some embodiments, the time domain configuration of the power saving signal includes: the starting time domain configuration of the power saving signal.

[0167] For the relevant description of the starting time domain configuration here, reference can be made to the foregoing embodiments, and it will not be repeated here.

[0168] The starting time domain configuration includes: the offset of the starting time domain position of the power saving signal relative to the reference time point.

[0169] In some embodiments, the reference time point can be a paging occasion. Thus, the offset of the time domain position of the power saving signal relative to the reference time point includes, but is not limited to: the offset of the time domain position of the power saving signal relative to the paging occasion.

[0170] In some embodiments, the power saving signal configuration includes at least one of the following identifiers:

[0171] An identifier for identifying whether the UE supports the use of the power saving signal in the inactive state;

[0172] An identifier for identifying whether the UE supports the use of the power saving signal in the idle state;

[0173] An identifier for indicating whether the UE expects to use a power saving signal in the inactive state;

[0174] An identifier for indicating whether the UE expects to use a power saving signal in the non-idle state;

[0175] An identifier for indicating the time domain configuration of the power saving signal when using the power saving signal in the inactive state;

[0176] An identifier for indicating the time domain configuration of the power saving signal when using the power saving signal in the idle state.

[0177] In some embodiments, the auxiliary information further includes at least one of the following:

[0178] The paging probability of the UE;

[0179] The mobility information of the UE;

[0180] The indication information of the enhanced coverage characteristics of the UE;

[0181] An identifier for indicating the time domain configuration of the power saving signal when using the power saving signal in the inactive state;

[0182] An identifier for indicating the time domain configuration of the power saving signal when using the power saving signal in the idle state.

[0183] For a detailed description of any one of the paging probability, mobility information, and indication information of the enhanced coverage characteristics of the UE here, reference can be made to any of the foregoing embodiments, and details will not be repeated here.

[0184] In some embodiments, the method further includes:

[0185] S200: Receive request information through an interface between base stations. This request message is used to request the auxiliary information of the UE. After receiving this request message, the second base station can return the auxiliary information to the first base station through the interface between base stations, or can return the auxiliary information to the first base station through a feedback link or other means. No matter which way the second base station directly sends the auxiliary information to the first base station, it can reduce the transmission path length for the first base station to obtain the auxiliary information.

[0186] The S210 may include: Sending the auxiliary information to the first base station through an interface between base stations according to the request information.

[0187] In some embodiments, the S200 may include: Receiving, through an interface between base stations, a request for obtaining a UE context sent by the first base station and carrying the request information.

[0188] Carrying the request information through the request for obtaining a UE context realizes the multiplexing of message signaling, simplifies the signaling for interaction between base stations, and reduces signaling overhead.

[0189] In some embodiments, as Figure 5A shown, S210 may include: S211:

[0190] S211: Send a UE context acquisition request response carrying the auxiliary information to the first base station through an interface between base stations.

[0191] By carrying the request information in the UE context acquisition request response, multiplexing of message signaling is achieved, simplifying the signaling interaction between base stations and reducing signaling overhead.

[0192] In some embodiments, the UE context acquisition request response is sent based on the UE context acquisition request of the first base station;

[0193] Or,

[0194] The UE context acquisition request response is sent based on protocol regulations.

[0195] The UE context acquisition request response may be actively sent by the second base station. For example, according to protocol agreements or based on prior negotiation with other base stations within the TA or NA of the UE, the second base station actively sends a UE context acquisition request response carrying auxiliary information.

[0196] In some embodiments, the UE context acquisition request response may be formed and sent according to the UE context acquisition request.

[0197] It should be noted that: If the second base station does not currently have the UE context, the UE context carried in the UE context acquisition request response may be empty at this time. If the second base station does not have the auxiliary information of the UE but has the UE context, the UE context acquisition request response carries the UE context, and the carried auxiliary information may be empty. If the second base station does not have the auxiliary information of the UE and also has the UE context, then the non-empty auxiliary information and UE context are both carried in the UE context acquisition request response. In this way, when the first base station receives the empty auxiliary information or UE context, it knows that the second base station lacks the auxiliary information or UE context of the UE.

[0198] In some embodiments, the UE context acquisition request response further includes: the context of the UE;

[0199] The auxiliary information and the UE context acquisition are located in different information elements (IEs);

[0200] Or,

[0201] The auxiliary information and the UE context are located in the same IE.

[0202] The auxiliary information and UE context can be located in the same IE where the auxiliary information and UE context are obtained, or can be located in different IEs, which can be configured according to communication requirements.

[0203] For example, in some embodiments, a UE Radio Capability for Paging IE for UE paging is newly added to the obtained UE context request response, and this IE is specifically used to carry the auxiliary information. While the UE context is still carried in the IE that is scheduled to carry the UE context in the obtained UE context request response.

[0204] For another example, there are some reserved bits or reserved fields in the IE that is scheduled to carry the UE context, and the auxiliary information can also be carried in the reserved bits or reserved fields in the IE that is scheduled to carry the UE context.

[0205] In some embodiments, S210 may include:

[0206] S212: Send a radio access network (RAN) paging message carrying the auxiliary information to the first base station through an interface between base stations.

[0207] The auxiliary information can be interacted in the RAN paging message. In this way, the interaction of the UE's auxiliary information can be achieved without introducing new signaling, which has strong compatibility with the prior art and small signaling overhead.

[0208] In some embodiments, the RAN paging message further includes: wireless paging information for paging the UE; the wireless paging information and the auxiliary information are located in different IEs;

[0209] Or,

[0210] The wireless paging information and the auxiliary information are located in the same IE.

[0309] Combined with any of the above embodiments, several specific examples are provided:

[0310] Example 1:

[0311] In the narrowband communication of R15, only the application of the power-saving signal in the idle state is considered. At this time, the auxiliary information supported by the UE for the power-saving signal is reported to the base station in the connected state through the UE capability (UE-RadioPagingInfo), and then the base station notifies the core network through the UE capacity info notification message sent to the core network. Subsequently, the core network will add the auxiliary information supported by the UE for the power-saving signal (UE RadioCapability for Paging) to the paging message sent to the RAN, which includes the UE capability (UE-RadioPagingInfo). If this mechanism is introduced into the inactive state of NR, when the base station needs to initiate a paging message to the UE, it needs to obtain the UE capability. This document protects the transfer of the auxiliary information supported by the UE for the power-saving signal during the interaction between the base station interfaces, thus avoiding the base station from obtaining this information from the core network.

[0312] Example 2: The auxiliary information supported by the UE for the power-saving signal is transferred during the interaction between the base station interfaces. The auxiliary information can be used to indicate at least one of the following: whether the UE supports the power-saving signal in the inactive state and / or the idle state; whether the UE hopes to use the power-saving signal in the active state and / or the idle state; when using the power-saving signal in the active state and / or the idle state, the start and end time configuration of the power-saving symbol can be an offset value offset relative to a certain reference point, such as an offset value relative to the paging PO; this offset value is closely related to the implementation of the UE; the paging probability of the user equipment, which is obtained by the base station from the core network; the mobility information of the user equipment (this information is implemented by the base station algorithm);

[0313] Whether the user equipment supports the coverage enhancement feature.

[0314] In some cases, a request indication for obtaining auxiliary information on the UE's support for power-saving signals is added to the base station - to - base station interaction message RETRIEVE UE CONTEXT REQUEST; as an embodiment, it can be explicitly indicated by a flag. When the value of this flag is "1", it means that auxiliary information needs to be requested. In some cases, a response on the UE's support for power-saving signals is added to the base station - to - base station interaction message RETRIEVE UE CONTEXT REQUEST. As an implementation manner, the request identifier adds the auxiliary information on the UE's support for power-saving signals in the response to obtaining the context. As an implementation manner, the auxiliary information on the UE's support for power-saving signals can be added to the response to obtaining the context based on a pre - defined protocol. As an implementation manner, the UE RadioCapability for Paging IE is added to RETRIEVE UE CONTEXT REQUEST to carry the auxiliary information on the UE's support for power-saving signals.

[0315] Example 3:

[0316] When interacting between base station interfaces, auxiliary information on the UE's support for power-saving signals is transmitted. This auxiliary information can be used to indicate at least one of the following: whether the UE supports power-saving signals in the inactive state and / or the idle state; whether the UE wishes to use power-saving signals in the active state and / or the idle state; when using power-saving signals in the active state and / or the idle state, the start and end time configuration of the power-saving signal can be an offset value offset relative to a certain reference point, such as an offset value relative to the paging PO; this offset value is closely related to the UE's implementation; the paging probability of this user equipment, which is obtained by the base station from the core network;

[0317] the mobility information of this user equipment (this information is implemented by the base station algorithm);

[0318] whether this user equipment supports the coverage enhancement feature.

[0319] An auxiliary information request for the UE's support for power-saving signals is added to the base station - to - base station interaction message RAN PAGING. As an implementation manner, the auxiliary information on the UE's support for power-saving signals can add a new IE in this message to carry the auxiliary information on the UE's support for power-saving signals; as an implementation manner, the auxiliary information on the UE's support for power-saving signals can extend the original UE - RadioPagingInfo to carry the auxiliary information on the UE's support for power-saving signals.
