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

[0031] Next, with reference to the accompanying drawings, the method for transmitting system information provided by the embodiments of this application will be described in detail through some embodiments and their application scenarios.

[0032] As Figure 2 shown, an embodiment of the present invention provides a method 200 for transmitting system information. This method can be executed by a network-side device. In other words, this method can be executed by software or hardware installed in the network-side device. The method includes the following steps:

[0033] S202: The network-side device determines at least one dimension included in the target cell provided by the network-side device.

[0034] The network-side device provides a target cell. According to the service types and / or service load distribution within 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.

[0035] One dimension in the at least one dimension corresponds to at least one of the following:

[0036] A sub-region of the target cell;

[0037] A subspace of the target cell;

[0038] A sub-cell of the target cell;

[0039] Part of the discovery signal beams transmitted by the network-side device;

[0040] A beam set, where the beam set includes part of the beams transmitted by the network-side device.

[0041] Figures 3a - 3c is a dimensional schematic diagram provided by an embodiment of the present invention. As Figure 3a shown, one of the dimensions 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 the 31st floor, and communication services for aircraft such as unmanned aerial vehicles (UAVs). The types of services and / or the distribution of service loads for serving ground services, communication services for floor residents, and aircraft communication services may be different.

[0042] As Figure 3b shown, one of the dimensions corresponds to a sub-region of the target cell. In the figure, one side of dimension 0 is for the dimension of square coverage, and the other side of dimension 1 is for the dimension of lake coverage, which are respectively used for communication services for dense crowds and sparse user communication services on the lake.

[0043] As Figure 3c shown, one of the dimensions corresponds to a sub-cell of the target cell. Figure 3c It includes a macro coverage dimension providing wide-area coverage and 3 micro coverage dimensions providing hot-spot coverage or shadow-area coverage.

[0044] In addition, one of the dimensions may also correspond to part of the beams transmitted by the network-side device, including: part of the discovery signal beams transmitted by the network-side device; a beam set, where the beam set includes part of the beams transmitted by the network-side device. That is, the network-side device sends the system information corresponding to the part of the beams on the part of the beams.

[0045] The types of services in different dimensions are different, and the required system information may vary. When a system information is only required by the services in a certain dimension area, broadcasting the system information in the entire cell causes waste of wireless resources and interference to neighboring cells.

[0046] The service loads in different dimensions may be different, and the energy consumption targets for the network operation to receive system information sent by the sending system also vary. For a piece of system information, if a unified short sending period is adopted throughout the cell, then for dimensions with sparse services, fewer users will benefit, while the energy consumption for sending system information is the same as that for dimensions with dense services, resulting in a waste of resources. On the contrary, if a unified long sending period is adopted throughout the cell, for dimensions with dense services, the terminal needs a longer time to obtain the desired system information, reducing the communication efficiency and affecting the user experience.

[0047] S204: Send the system information according to the system information sending configuration corresponding to the at least one dimension.

[0048] In one implementation, the system information sending configuration corresponding to the at least one dimension includes: the correspondence between the at least one dimension and the system information.

[0049] Take Figure 3a as an example. In the ground coverage dimension, send the system information according to the system information sending configuration corresponding to the ground coverage dimension (dimension 0). In the intermediate space coverage dimension (dimension 1), send the system information according to the system information sending configuration corresponding to the intermediate space coverage dimension. In the high space coverage dimension (dimension 2), send the system information according to the system information sending configuration corresponding to the high space coverage dimension. The system information sent in each dimension can be the same or different.

[0050] In one implementation, when the system information is only required for services in some dimensions, it can be sent only in those dimensions, avoiding the waste of radio resources and interference to neighboring cells caused by sending the system information throughout the cell. For example, the base station sends the scheduling configuration parameters of system information X in dimension 1, while not sending the scheduling configuration parameters of system information X in dimension 2. The UE determines accordingly that the base station provides the sending service of system information X in dimension 1, but does not provide the sending service of system information X in dimension 2.

[0051] In one implementation, for dimensions with sparse services, a long sending period can be adopted. On the contrary, for dimensions with dense services, a short sending period can be adopted, thereby avoiding resource waste and not reducing the communication efficiency.

[0052] Thus, the embodiments of the present application can send the system information according to the system information sending configuration corresponding to each dimension respectively, avoiding the waste of radio resources and interference to neighboring cells caused by sending the system information throughout the cell, and can also ensure the communication quality within the target cell.

[0053] In one implementation, the system information sending configuration corresponding to the at least one dimension includes: the scheduling parameters corresponding to the system information, and different dimensions can correspond to different scheduling parameters.

[0054] In one implementation, the terminal may first receive the scheduling parameters corresponding to the system information in one dimension, and then receive the system information according to the scheduling parameters. For example, the terminal receives the first scheduling parameter in the first dimension, and then receives the first system information according to the first scheduling parameter. After the terminal enters the second dimension from the first dimension, it receives the second scheduling parameter in the second dimension, and then receives the second system information corresponding to the second dimension according to the second scheduling parameter.

[0055] The scheduling parameters include at least one of the following:

[0056] Transmission mode, where the transmission mode includes one or both of the system message transmission based on the UE request and the network-side device actively sending the system message;

[0057] Transmission period, such as a long period or a short period, etc.;

[0058] Transmission time window.

[0059] In one implementation, the network-side device may also send scheduling parameters to the terminal, and the scheduling parameters include at least one of the following:

[0060] Whether it is sending; for example, it may include whether it is currently sending;

[0061] Transmission mode;

[0062] Transmission period;

[0063] Transmission time window;

[0064] Wherein, the transmission mode includes one or both of the system message transmission based on the UE request and the network-side device actively sending the system message.

[0065] In one implementation, the scheduling parameter may be an indication message.

[0066] 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.

[0067] In one implementation, the terminal sends a request message to the network-side device, and the network-side device sends a response message to the terminal. Optionally, at least part of the transmission configuration of the system information corresponding to the at least one dimension is carried in the response message, and the terminal may receive the system information according to this transmission configuration.

[0068] The system information of NR includes multiple Minimum System Information (MSI) and Other System Information (OSI). Among them, MSI includes Master Information Block, MIB, and SIB1 (System Information Block 1), which are actively broadcast by the base station; while OSI includes all other system information, which can be actively broadcast by the base station or sent and configured on demand by the base station through SIB1. The UE sends a system information transmission request to the base station according to the on-demand sending configuration, requests the base station to send system information, and then the UE receives the system information.

[0069] In one implementation, the request message includes at least one of the following:

[0070] A system information transmission request based on the preamble of the Physical Random Access Channel (PRACH). If the base station carries the PRACH-based system information request transmission configuration, i.e., SI-RequestConfig, including the PRACH resource configuration for initiating the system information request, including the PRACH occasion and PRACH preamble, in SIB1, the terminal can request system information from the base station by sending a PRACH.

[0071] A system information transmission request based on Msg3 in the random access process; if the PRACH-based system information request transmission configuration is not carried in SIB1, the UE can initiate a random access process based on the Radio Resource Control system information request RRCSystemInfoRequest (SRB0), and indicate the request for system information in RRCSystemInfoRequest.

[0072] A system information transmission request based on a dedicated message. A terminal in the RRC_CONNECTED state can send a system information request to the base station through the dedicated RRC signaling dedicated SIB request DedicatedSIBRequest (SRB1), and indicate the request for system information in DedicatedSIBRequest.

[0073] In one implementation, after the dimension where the terminal is located changes, the terminal should resend the request. For example, the terminal sends a first request to the network device in a first dimension, and the network device feeds back a first response message to the terminal. At least part of the first transmission configuration of the first system information corresponding to the first dimension is carried in the first response message. The terminal can receive the first system information in the first dimension according to the first transmission configuration. The terminal enters a second dimension from the first dimension, sends a second request to the network device in the second dimension, and the network device feeds back a second response message to the terminal. At least part of the second transmission configuration of the second system information corresponding to the second dimension is carried in the second response message. The terminal can receive the second system information in the second dimension according to the second transmission configuration.

[0074] In one implementation, the system information transmission configuration corresponding to the at least one dimension further includes: resource configuration information. In one implementation, this embodiment may further include transmitting resource configuration information. The resource configuration information is used to configure the uplink channel resources for transmitting the request message. The uplink channel resources include the position of the time-frequency resource window for transmitting the request message and / or the signal sequence for transmitting the request message. The network device can configure the uplink channel resources by dimension, and the terminal determines the uplink channel resources corresponding to the dimension where it resides and uses the uplink channel resources to transmit the request message.

[0075] In one implementation, the request message satisfies at least one of the following:

[0076] The request message explicitly or implicitly indicates the dimension identifier corresponding to the system information requested by the terminal from the network-side device. This dimension can be the dimension where the terminal is located. That is, the terminal is in the first dimension and requests the network-side device to send the system information corresponding to the first dimension. This dimension can also be the second dimension. That is, the terminal is in the first dimension but requests the base station to send the 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 can send a system information request to the base station, requesting the base station to send the system information of the second dimension to the UE. The response message of the request message is used to indicate that the terminal receives the system information of the dimension corresponding to the at least one dimension identifier. The request message explicitly or implicitly indicates that the system information requested by the terminal from the network-side device is applicable to at least one of the at least one dimension. In one implementation, the system information sending configuration corresponding to the at least one dimension further includes: a first prohibited time. In one implementation, the embodiments of the present application may further include sending a first prohibited time. The first prohibited time is used to indicate that the terminal is prohibited from sending a system information request within the first prohibited time after sending the system information sending request. To prevent the terminal from frequently sending system information requests, NR introduces a timer T350. When the UE sends a system information request through dedicated information (DedicatedSIBRequest), after the terminal sends DedicatedSIBRequest, T350 is started. During the running of T350, the terminal cannot send DedicatedSIBRequest again. When the terminal receives the requested system information, if T350 is still running, then T350 is stopped.

[0077] In one implementation, the system information sending configuration corresponding to the at least one dimension is carried in the system information, such as SIB1. The system information can be applicable to at least one of the dimensions.

[0078] In one implementation, after S202, it further includes: sending a paging message, where 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.

[0079] In one implementation, the system information sending configuration corresponding to the at least one dimension further includes: a system information update paging message, where the system information update paging message is used to notify the terminal to receive updated system information in the target dimension. The target dimension is the dimension where the UE is located or other dimensions preconfigured by the network-side device.

[0080] In one implementation, after the dimension where the terminal is located changes, an updated paging message should be resent. For example, the terminal sends a first updated paging message to the network device in the first dimension and receives first system information in the first dimension. The terminal enters the second dimension from the first dimension, sends a second updated paging message to the network device in the second dimension, and the terminal can receive second system information in the second dimension.

[0081] In one implementation, the system information may carry at least one of the following:

[0082] A first indication, where the first indication is used to indicate the dimension to which at least one piece of system information in the system information applies;

[0083] A second indication, where the second indication is used to indicate the dimension to which at least one parameter in the system information applies.

[0084] In one implementation, the system information transmission configuration corresponding to the at least one dimension includes: a first indication, where the first indication is used to indicate the dimension to which at least one piece of system information in the system information applies. For example, the base station can indicate whether system information X applies to all dimensions or to some dimensions, and this indication can be carried in another piece of system information that is continuously broadcast, such as SIB1, or can be carried in system information X.

[0085] In one implementation, through protocol agreement or predefined, at least one piece of system information can apply to all dimensions, such as SIB1. Among the at least one piece of system information that applies to all dimensions, scheduling parameters for the transmission of system information in each dimension are included, and the scheduling parameters are used for the UE to determine the transmission period and transmission time window of system information in each dimension to perform the reception of system information.

[0086] In one implementation, the first indication is included in at least one piece of system information sent by the network device. For example, SIB1.

[0087] 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 can indicate whether a certain parameter in system information X applies to all dimensions or to some dimensions. The base station can configure dedicated system parameters for a certain dimension, such as the initial values of some RRC timers, the transmission power of cell discovery signals, the transmission period of a piece of system information, paging resource configuration, the search resource configuration of downlink scheduling signals, PRACH configuration, etc.

[0088] Next, a method for transmitting system information according to another embodiment of the present invention will be described in detail in conjunction with Figure 4 It can be understood that Figure 2The interaction between the network device and the terminal device described from the perspective of the network device is the same as the description from the perspective of the terminal device in the method shown in Figure 4 To avoid repetition, relevant descriptions are appropriately omitted.

[0089] Figure 4 It is a schematic flow diagram of the method for transmitting system information according to an embodiment of the present invention, which can be applied to the terminal side. As Figure 4 shown, the method 400 includes:

[0121] In one implementation, after the terminal enters the second dimension from the first dimension, the terminal receives a system information update paging message in the second dimension; in response to the system information update paging message, the terminal receives updated system information in the second dimension.
