Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technology, and in particular to a method, device and storage medium for sending and receiving auxiliary information. Background Art

[0002] In wireless communication systems, such as the new radio (NR) system, the communication interface between the user equipment (UE) and the base station is called the Uu interface. In order to support direct communication between user equipments, the sidelink communication mode is introduced, and the interface between UEs is PC-5. Three transmission modes are supported on the sidelink, namely unicast, multicast and broadcast.

[0003] A UE does not directly connect to a base station, but communicates with the base station through another UE's relay, which is called relay communication. In relay communication, the user equipment that is not directly connected to the base station is called remote user equipment (remote user equipment, remote UE), and the user equipment that is directly connected to the base station is called relay user equipment (relay user equipment, relay UE).

[0004] When the remote UE and the relay UE are in an idle state or an inactive state, the remote UE can send a system information request to the relay UE. After receiving the system information request, the relay UE needs to obtain the system information from the base station and then forward it to the remote UE. In the process of obtaining the system information through the relay UE, there is a problem of failure or incompleteness in obtaining the system information. Summary of the invention

[0005] In view of this, the present disclosure provides a method, device and storage medium for sending and receiving auxiliary information.

[0072] The embodiments of the present disclosure are now further described in conjunction with the accompanying drawings and specific implementation methods.

[0073] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the embodiments of the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0074] like Figure 1 As shown, the method for transmitting auxiliary information provided by the embodiment of the present disclosure can be applied to a wireless communication system 100, which may include but is not limited to a network device 101 and multiple user equipments. The user equipment is configured to support carrier aggregation, and the user equipment can be connected to multiple carrier components of the network device 101, including a main carrier component and one or more auxiliary carrier components.

[0075] Among them, the user equipment directly connected to the network device 101 and providing a relay function is called a relay user equipment (relay User Equipment, relay UE) 102, and the user equipment not directly connected to the network device 101 is called a remote user equipment (remote User Equipment, remote UE) 103. The relay UE 102 communicates with the remote UE 103 based on a sidelink, and the remote UE 103 communicates with the network device 101 through the relay UE 102.

[0076] It should be understood that the above wireless communication system 100 can be applied to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for micro wave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems, etc.

[0077] The user equipment shown above may be user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication device, terminal agent or user equipment, etc. The user equipment may have a wireless transceiver function, which can communicate with one or more network devices of one or more communication systems (such as wireless communication) and receive network services provided by the network device 102, where the network devices include but are not limited to the base station shown in the figure.

[0078] Among them, the user equipment can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a user equipment in a future 5G network, or a user equipment in a future evolved PLMN network, etc.

[0079] The network device 101 may be an access network device (or access network point). Among them, the access network device refers to a device that provides network access functions, such as a radio access network (RAN) base station, etc. The network device may specifically include a base station (BS) device, or a base station device and a wireless resource management device for controlling the base station device, etc. The network device may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station, etc. The network device may be a wearable device or a vehicle-mounted device. The network device may also be a communication chip with a communication module.

[0080] For example, the network device 101 includes but is not limited to: a next-generation base station (gnodeB, gNB) in 5G, an evolved node B (evolved node B, eNB) in an LTE system, a radio network controller (radio network controller, RNC), a node B (node ​​B, NB) in a WCDMA system, a wireless controller under a CRAN system, a base station controller (basestationcontroller, BSC), a base transceiver station (base transceiver station, BTS) in a GSM system or a CDMA system, a home base station (for example, home evolved nodeB, or home node B, HNB), a baseband unit (basebandunit, BBU), a transmission point (transmitting and receiving point, TRP), a transmitting point (transmittingpoint, TP) or a mobile switching center, etc.

[0081] During the communication between UE and base station, if a certain system information block (SIB) is not broadcast, the UE in idle or inactive state can send a system information request to the base station. After receiving the system information request, the base station broadcasts the corresponding SIB, and the UE obtains the SIB through the broadcast.

[0082] In relay communication, the remote UE 103 needs to obtain the SIB through the relay UE 102. In this process, the request for system information is related to the capability of the relay UE 102, so the reasons for failure or incompleteness in obtaining system information may include:

[0083] First, the relay UE 102 does not have the corresponding capability, and therefore cannot obtain the system information and the corresponding version of the system information required by the remote UE 103 .

[0084] Second, the capabilities of the remote UE 103 and the relay UE 102 are different. If the system information requested by the remote UE 103 exceeds the capability of the relay UE 102 , the relay UE 102 cannot obtain the corresponding system information.

[0085] The above reasons may result in failure in requesting system information, or incomplete system information sent by relay UE 102, resulting in waste of resources.

[0086] An embodiment of the present disclosure provides a method for transmitting auxiliary information. Figure 2 is a flow chart showing a method for transmitting auxiliary information according to an exemplary embodiment. Figure 2 As shown, the method includes:

[0087] Step S201: The first user equipment 102 sends auxiliary information to the second user equipment 103. The auxiliary information is used to indicate the capability of the first user equipment UE102 to acquire system information.

[0088] Step S202: The second user equipment 103 receives auxiliary information sent by the first user equipment UE102, wherein the auxiliary information is used to indicate a capability of the first user equipment UE102 to acquire system information.

[0089] Step S203 : The first user equipment 102 receives a system information request message sent by the second user equipment 103 .

[0090] Step S204: The first user equipment 102 sends a request for acquiring system information corresponding to the system information request message to the network equipment 101.

[0091] Step S205 : The network device 101 sends system information to the first user equipment 102 .

[0092] Step S206: After the first user equipment 102 successfully receives the system message, it sends the system information to the second user equipment 103; or, after the first user equipment 102 fails to receive the system message, it sends an indication of failure to obtain the system information to the second user equipment 103.

[0093] In some possible implementations, system information (SI) is necessary information provided by the network device 101 to user equipment in the RRC_IDLE state and the RRC_CONNECTED state, such as cell access information and public radio resource configuration information, or cell selection and cell reselection information. The network device 101 generally broadcasts the system information through a radio resource control RRC message.

[0094] In some possible implementations, the first user equipment 102 is a relay UE 102. The second user equipment 103 is a remote UE 103.

[0095] In some possible implementations, before sending the system information request message, the first user equipment 102 sends auxiliary information to the second user equipment 103, and the second user equipment 103 learns the capability of the first user equipment 102 to obtain system information according to the auxiliary information.

[0096] In the embodiment of the present disclosure, the first user equipment 102 sends auxiliary information to the second user equipment 103, and the second user equipment 103 can learn the capability of the first user equipment 102 to obtain system information according to the auxiliary information. Thus, the second user equipment 103 can send a system information request that meets the acquisition capability of the first user equipment 102 to the first user equipment 102. Then, the first user equipment 102 can obtain the system information required by the second user equipment 103 from the network device 101 within its own capability, thereby improving the problem of failure to obtain system information due to insufficient acquisition capability of the first user equipment 102.

[0097] The embodiment of the present disclosure provides a method for sending auxiliary information, which is executed by a first user equipment UE102. Figure 3 is a flow chart showing a method for sending auxiliary information according to an exemplary embodiment. Figure 3 As shown, the method includes:

[0098] Step S301: The first user equipment UE102 sends auxiliary information to the second user equipment UE103; wherein the auxiliary information is used to indicate the capability of the first user equipment UE102 to acquire system information.

[0099] In some possible implementations, the first user equipment 102 is a relay UE 102. The second user equipment 103 is a remote UE 103.

[0100] In some possible implementations, the relay UE 102 may send the auxiliary information via a sidelink unicast method, or may send the auxiliary information via a sidelink broadcast method.

[0101] In the disclosed embodiment, the relay UE 102 can send auxiliary information to the remote UE 103, and the remote UE 103 can learn the ability of the relay UE 102 to obtain system information based on the auxiliary information. Therefore, the remote UE 103 can send a system information request that meets the acquisition capability of the relay UE 102 to the relay UE 102, and then the relay UE 102 can obtain the system information from the network device 101 within its own capability, thereby improving the problem of failure to obtain system information due to insufficient acquisition capability of the relay UE 102.

[0102] The embodiment of the present disclosure provides a method for sending auxiliary information. The method is executed by a first user equipment UE102. The method includes:

[0108] Capability indication information of the transmission capability on the Uu interface.

[0109] In some possible implementations, the Uu interface is a communication interface between the UE and the base station.

[0110] In some possible implementations, the indication information of the system information is used to indicate: the type of system information that can be obtained from the network device 101. The types of system information blocks SIB in the system information SI include SIB1-SIB13.

[0111] In an example, the indication information of the system information is used to indicate that the system information block SIB1-9 can be obtained from the network device 101, but the system information SIB1-10 cannot be obtained.

[0112] In some possible implementations, the capability indication information of the transmission capability of the Uu interface is used to indicate whether a specific communication capability is supported, wherein the specific communication capability may be a default one or may be set in advance, and the specific communication capability may also be modifiable.

[0113] In the disclosed embodiment, the relay UE 102 can send auxiliary information of different aspects to the remote UE 103, so that the remote UE 103 can more accurately know the ability of the relay UE 102 to obtain system information, which is conducive to sending a system information request message that is compatible with the ability of the relay UE 102.

[0114] The embodiment of the present disclosure provides a method for sending auxiliary information, which is executed by a first user equipment UE102.
