As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0033] The following describes in detail the method for transmitting system information provided by the embodiment of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0034] As shown in FIG2 , an embodiment of the present invention provides a method 200 for transmitting system information. The method may be performed by a network-side device. In other words, the method may be performed by software or hardware installed on the network-side device. The method includes the following steps:

[0035] S202: The network-side device determines at least one dimension included in the target cell provided by the network-side device.

[0036] The network side device provides a target cell. According to the service type and / or service load distribution in the target cell, the coverage area and / or space of the target cell can be divided into at least one dimension according to the service provision requirements.

[0037] One of the at least one dimension corresponds to at least one of the following:

[0038] a sub-area of ​​the target cell;

[0039] a subspace of the target cell;

[0040] a sub-cell of the target cell;

[0041] Part of the discovery signal beam sent by the network side device;

[0042] A beam set includes part of the beams sent by the network-side device.

[0043] Figures 3a-3c are schematic diagrams of dimensions provided by an embodiment of the present invention. As shown in Figure 3a, one dimension corresponds to a subspace of the target cell. The target cell includes a ground coverage dimension (dimension 0), an intermediate space coverage dimension (dimension 1), and a higher space coverage dimension (dimension 2), which are mainly used to serve ground services, such as services for multiple UEs, communication services for residents on floor 31, and communication services for aircraft such as unmanned aerial vehicles (UAVs). The types of services and / or service load distributions for serving ground services, communication services for floor residents, and communication services for aircraft can be different.

[0044] As shown in Figure 3b, one dimension corresponds to a sub-area of ​​the target cell. Dimension 0 on one side of the figure is used for square coverage, and dimension 1 on the other side is used for lake coverage, respectively for communication services for densely populated groups and sparsely populated users on the lake.

[0045] As shown in Figure 3c, one dimension corresponds to one sub-cell of the target cell. Figure 3c includes one macro coverage dimension providing wide area coverage and three micro coverage dimensions providing hotspot coverage or shadow area coverage.

[0046] In addition, one dimension may correspond to a portion of the beams sent by the network device, including: a portion of the discovery signal beams sent by the network device; and a beam set, wherein the beam set includes the portion of the beams sent by the network device. That is, the network device sends system information corresponding to the portion of the beams on the portion of the beams.

[0047] Different services in different dimensions have different types and may require different system information. When a system information is only needed by services in a certain dimension, broadcasting the system information in the entire cell will waste wireless resources and interfere with neighboring cells.

[0048] Traffic loads may vary across different dimensions, and the energy consumption targets for sending system information that network operators can accept also differ. If a uniform short transmission cycle is used across all cells for a piece of system information, fewer users will benefit in dimensions with low traffic, while the energy consumption for sending system information will be the same as in dimensions with high traffic, resulting in a waste of resources. Conversely, if a uniform long transmission cycle is used across all cells, terminals in dimensions with high traffic will take longer to receive the desired system information, reducing communication efficiency and impacting the user experience.

[0049] S204: Send system information according to the system information sending configuration corresponding to the at least one dimension.

[0050] In one implementation, the system information sending configuration corresponding to the at least one dimension includes: a corresponding relationship between the at least one dimension and the system information.

[0051] Taking Figure 3a as an example, in the ground coverage dimension, system information is sent according to the system information sending configuration corresponding to the ground coverage dimension (dimension 0). In the intermediate spatial coverage dimension (dimension 1), system information is sent according to the system information sending configuration corresponding to the intermediate spatial coverage dimension. In the high spatial coverage dimension (dimension 2), system information is sent according to the system information sending configuration corresponding to the high spatial coverage dimension. The system information sent in each dimension can be the same or different.

[0052] In one implementation, when system information is only needed for services within a certain dimension, it can be sent only in that dimension, avoiding the waste of radio resources and interference to neighboring cells caused by sending the system information throughout the entire cell. For example, if the base station sends the scheduling configuration parameters for system information X in dimension 1 but does not send the scheduling configuration parameters for system information X in dimension 2, the UE can determine that the base station provides the system information X transmission service in dimension 1 but does not provide the system information X transmission service in dimension 2.

[0053] In one implementation, a long sending cycle may be used for dimensions with sparse services, and conversely, a short sending cycle may be used for dimensions with dense services, thereby avoiding waste of resources and not reducing communication efficiency.

[0054] Therefore, the embodiment of the present application can send system information according to the system information sending configuration corresponding to each dimension, thereby avoiding the waste of wireless resources and interference to neighboring cells caused by sending the system information in the entire cell, and can also ensure the communication quality in the target cell.

[0055] In one implementation, the system information sending configuration corresponding to the at least one dimension includes: a scheduling parameter corresponding to the system information, and different dimensions may correspond to different scheduling parameters.

[0056] In one implementation, a terminal may first receive the scheduling parameters corresponding to the system information in one dimension, and then receive the system information based on the scheduling parameters. For example, the terminal may receive a first scheduling parameter in the first dimension, and then receive the first system information based on the first scheduling parameter. After entering the second dimension from the first dimension, the terminal may receive a second scheduling parameter in the second dimension, and then receive the second system information corresponding to the second dimension based on the second scheduling parameter.

[0057] The scheduling parameters include at least one of the following:

[0058] A sending mode, wherein the sending mode includes one or both of sending the system message based on a UE request and actively sending the system message by a network side device;

[0059] Sending cycle, such as long cycle or short cycle;

[0060] Sending time window.

[0061] In one implementation, the network-side device may further send a scheduling parameter to the terminal, where the scheduling parameter includes at least one of the following:

[0062] Whether it is being sent; for example, it may include whether it is being sent;

[0063] Delivery method;

[0064] Sending cycle;

[0065] Sending time window;

[0066] The sending manner includes one or both of sending the system message based on a UE request and actively sending the system message by a network side device.

[0067] In one implementation, the scheduling parameter may be indication information.

[0068] In one implementation, at least part of the system information corresponding to the at least one dimension is sent by the network side device in response to a request message sent by the terminal.

[0069] In one implementation, the terminal sends a request message to the network side device, and the network side device feeds back a response message to the terminal. Optionally, the response message carries at least part of the sending configuration of the system information corresponding to the at least one dimension, and the terminal can receive the system information according to the sending configuration.

[0070] The system information of NR includes multiple minimum system information sets (MSI) and other system information sets (OSI). The MSI includes the Master Information Block, MIB and SIB1 (System Information Block 1, SIB1), which are actively broadcast by the base station; while the OSI includes all other system information, which can be actively broadcast by the base station or configured by the base station on demand through SIB1. The UE sends a system information request to the base station according to the on-demand transmission configuration, requesting the base station to send system information, and then the UE receives the system information.

[0071] In one implementation, the request message includes at least one of the following:

[0072] System information sending request based on the physical random access channel (PRACH) preamble. If the base station carries the PRACH-based system information request sending configuration in SIB1, i.e., SI-RequestConfig, including the PRACH resource configuration for initiating the system information request, including the PRACH occasion and PRACH preamble, the terminal can request system information from the base station by sending PRACH.

[0073] System information sending request based on Msg3 in the random access process; if SIB1 does not carry the system information request sending configuration based on PRACH, the UE can initiate a random access process based on the radio resource control system information request RRCSystemInfoRequest (SRB0), and indicate the request system information in RRCSystemInfoRequest.

[0074] System information transmission request based on dedicated message: A terminal in the RRC connected (RRC_CONNECTED) state can send a system information request to the base station through a dedicated RRC signaling dedicated SIB request DedicatedSIBRequest (SRB1), indicating the requested system information in the DedicatedSIBRequest.

[0075] In one implementation, the terminal should resend the request after the dimension in which it is located changes. For example, the terminal sends a first request to the network-side device in the first dimension, and the network-side device feeds back a first response message to the terminal. The first response message carries at least part of the first transmission configuration of the first system information corresponding to the first dimension, and the terminal can receive the first system information in the first dimension according to the first transmission configuration. The terminal enters the second dimension from the first dimension, sends a second request to the network-side device in the second dimension, and the network-side device feeds back a second response message to the terminal. The second response message carries at least part of the second transmission configuration of the second system information corresponding to the second dimension, and the terminal can receive the second system information in the second dimension according to the second transmission configuration.

[0076] In one implementation, the system information sending configuration corresponding to the at least one dimension further includes: resource configuration information. In one implementation, this embodiment may further include sending resource configuration information, wherein the resource configuration information is used to configure the uplink channel resources for sending the request message, and the uplink channel resources include the position of the time-frequency resource window for sending the request message and / or the signal sequence for sending the request message. The network-side device can configure the uplink channel resources by dimension, and the terminal determines the uplink channel resources corresponding to the dimension based on the dimension in which it resides, and uses the uplink channel resources to send the request message.

[0077] In one implementation, the request message satisfies at least one of the following:

[0078] The request message explicitly or implicitly indicates the dimension identifier corresponding to the system information that the terminal requests the network-side device to send. The dimension may be the dimension in which the terminal is located, that is, the terminal is in the first dimension and requests the network-side device to send system information corresponding to the first dimension. The dimension may also be the second dimension, that is, the terminal is in the first dimension but requests the base station to send system information applicable to the second dimension. For example, when the terminal predicts that it will move from the current first dimension to the second dimension, it may send a system information request to the base station, requesting the base station to send system information of the second dimension to the UE. The response message to the request message is used to instruct the terminal to receive system information corresponding to the at least one dimension identifier. The request message explicitly or implicitly indicates that the terminal requests the network-side device to send system information applicable to at least one of the at least one dimension. In one implementation, the system information transmission configuration corresponding to the at least one dimension further includes: a first prohibition time. In one implementation, the embodiment of the present application may also include sending the first prohibition time, wherein the first prohibition time is used to instruct the terminal to prohibit sending system information requests within the first prohibition time after sending the system information transmission request. To prevent the terminal from frequently sending system information requests, NR introduces a timer T350. When the UE sends a system information request (DedicatedSIBRequest) through dedicated information, T350 is started after the terminal sends the DedicatedSIBRequest. During the running period of T350, the terminal cannot send the DedicatedSIBRequest again. When the terminal receives the requested system information, if T350 is still running, it will be stopped.

[0079] In one implementation, the system information sending configuration corresponding to the at least one dimension is carried in the system information, such as SIB1, and the system information may be applicable to at least one dimension.

[0080] In one implementation, after S202, the method further includes: sending a paging message, wherein the paging message is used to notify the terminal to receive updated system information in the target dimension. In response to the paging message, the terminal receives the updated system information.

[0081] In one implementation, the system information transmission configuration corresponding to the at least one dimension further includes: a system information update paging message, wherein the system information update paging message is used to notify the terminal to receive updated system information in a target dimension. The target dimension is the dimension in which the UE is located or other dimensions preconfigured by the network-side device.

[0082] In one implementation, the terminal should resend an update paging message after the dimension it is in changes. For example, the terminal sends a first update paging message to the network device in the first dimension and receives first system information in the first dimension. The terminal then enters the second dimension from the first dimension and sends a second update paging message to the network device in the second dimension, and the terminal can receive second system information in the second dimension.

[0083] In one implementation, the system information may carry at least one of the following:

[0084] a first indication, where the first indication is used to indicate a dimension to which at least one piece of system information in the system information applies;

[0085] A second indication, where the second indication is used to indicate a dimension to which at least one parameter in the system information applies.

[0086] In one implementation, the system information transmission configuration corresponding to the at least one dimension includes: a first indication, the first indication being used to indicate the dimension to which the at least one piece of system information in the system information applies. For example, the base station may indicate whether system information X applies to all dimensions or to some dimensions. The indication may be carried in another piece of system information that is consistently broadcast, such as SIB1, or may be carried in system information X.

[0087] In one implementation, at least one piece of system information may be applicable to all dimensions, such as SIB1, through protocol agreement or pre-definition. The at least one piece of system information applicable to all dimensions includes scheduling parameters for sending system information for each dimension. The scheduling parameters are used by the UE to determine the sending period and sending time window of the system information for each dimension to perform system information reception.

[0088] In one implementation, the first indication is included in at least one system information sent by the network side device, for example, SIB1.

[0089] In one implementation, the system information transmission configuration corresponding to the at least one dimension includes a second indication, where the second indication is used to indicate the dimension to which at least one parameter in the system information applies. The base station may indicate whether a parameter in the system information X applies to all dimensions or to some dimensions. The base station may configure dedicated system parameters for a certain dimension, such as the initial values ​​of some RRC timers, the transmit power of the cell discovery signal, the transmission period of a piece of system information, the paging resource configuration, the search resource configuration of the downlink scheduling signal, the PRACH configuration, etc.

[0090] The following describes in detail a method for transmitting system information according to another embodiment of the present invention in conjunction with FIG4 . It is understood that the interaction between the network device and the terminal device described from the perspective of the network device in FIG2 is the same as the description of the terminal device side in the method shown in FIG4 , and to avoid repetition, the relevant description is omitted as appropriate.

[0091] FIG4 is a schematic diagram of a method for transmitting system information according to an embodiment of the present invention, which can be applied on the terminal side. As shown in FIG4 , the method 400 includes:
