Technical field

The present application relates to the field of mobile communications, and in particular to a parameter configuration method, device, equipment and storage medium.

Background technique

In a mobile communication system, network equipment provides a cell for a terminal so that the terminal can perform cell switching and communicate through the switched cell. However, based on the current handover mechanism, the network device sends the parameter configuration of the target cell to the terminal through a reconfiguration message, that is, the reconfiguration message carries the specific parameters of the target cell. For NTN (Non-terrestrial Network, non-terrestrial network), because satellites move at high speed relative to fixed positions on the earth, terminals will frequently switch connected satellites. Accordingly, the terminal needs to use cell parameters of different target cells. When the terminal switches satellites, the network equipment will send the parameters of the target cell to the terminal through the RRC (Radio Resource Control) reconfiguration message, which results in high signaling overhead.

For convenience of description, in the embodiment of the present application, the above-mentioned devices that provide wireless communication functions for the terminal 10 are collectively referred to as network equipment. A connection can be established between the network device 20 and the terminal 10 through an air interface, so that communication, including signaling and data interaction, can be performed through the connection. The number of network devices 20 may be multiple, and communication between two adjacent network devices 20 may also be carried out in a wired or wireless manner. The terminal 10 can switch between different network devices 20 , that is, establish connections with different network devices 20 .

The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with network device functions may be different. For example, in 5G NR (New Radio, New Radio) systems, they are called gNodeB or gNB. As communications technology evolves, the name "network device" may change.

In some embodiments, the communication system shown in Figure 1 is applied in an NTN network architecture. For example, as shown in Figure 2, the NTN network architecture includes a terminal 10, a transfer device 30 and a ground station 40.

Among them, the relay device 30 and the ground station 40 can be understood as the network device 20 in the above embodiment, and the network device 20 is included to include a control module for providing gNB functions. The relay device 30 and the ground station 40 communicate through feeder link (feeder link) communicates to form an NTN service link distribution system.

That is to say, satellite 1 and satellite 2 use the same parameter configuration to configure a cell for the terminal. Therefore, the same parameter configuration can be used in the cells managed by satellite 1 and satellite 2.

It should be noted that the NTN network architecture shown in Figure 2 or Figure 3 is only an example. This application is not limited to the network architecture shown in Figure 2 or Figure 3, and other types of network structures are also applicable.

Figure 4 shows a flow chart of a parameter configuration method provided by an exemplary embodiment of the present application, which can be applied to the terminal and network equipment shown in Figure 1. The method includes at least part of the following content:

Step 401: The network device sends configuration signaling to the terminal. The configuration signaling indicates the parameter configuration of the first cell. The parameter configuration instructs the terminal to use all or part of the parameter configuration of the second cell. The first cell is a cell other than the serving cell.

In this embodiment of the present application, the network device may provide the terminal with parameter configuration of at least one target cell. The target cell is a cell that the terminal may select or access during the cell handover process. The parameter configuration of the first cell in the embodiment of the present application is the parameter configuration of the target cell provided by the network device to the terminal device.

Wherein, the first cell is a cell other than the serving cell. For example, the first cell is actually the target cell when the terminal performs cell handover. The first cell includes at least one target cell. The serving cell refers to the cell currently accessed by the terminal, and the second cell is a cell for which parameter configuration has been configured in the terminal. For example, the second cell is the serving cell or one of multiple target cells. The network device configures the parameter configuration of the first cell for the terminal, and the terminal can use the configured parameter configuration when switching to the first cell during cell handover.

The network device configures the parameter configuration of at least one target cell for the terminal, so that when the terminal performs cell handover, it can perform handover according to the parameter configuration of the target cell configured by the network device.

Step 402: The terminal receives the configuration signaling sent by the network device. The configuration signaling indicates the parameter configuration of the first cell. The parameter configuration instructs the terminal to use all or part of the parameter configuration of the second cell. The first cell is a cell other than the serving cell. .

In this embodiment of the present application, the network device sends configuration signaling to the terminal. After receiving the configuration signaling, the terminal can determine the parameter configuration of the first cell based on the configuration signaling and the parameter configuration of the second cell, thereby facilitating the terminal Switch to the first cell during cell handover.

The terminal receives the configuration signaling sent by the network device. According to the configuration signaling, it can determine the first cell configured by the network device for the terminal and the parameter configuration of the first cell. The first cell is actually the target of the terminal when performing cell switching. cell, and the parameter configuration indication of the first cell determines to use all or part of the parameter configuration of the second cell, that is, the terminal can directly use the parameter configuration of the second cell, which can save signaling overhead.

It should be noted that in the embodiment of the present application, the steps performed by the terminal can separately form a new embodiment, and the steps performed by the network device can also separately form a new embodiment, which is not limited in this application.

In the solution provided by the embodiment of this application, the terminal receives the configuration signaling sent by the network device, and based on the configuration signaling, the parameter configuration of the first cell indicated by the configuration signaling can be determined from the parameter configuration of the second cell, breaking the Network devices need to send parameter configurations to terminals, which in turn saves signaling overhead and improves resource utilization.

The parameter configuration indicated by the configuration signaling involved in this application includes a variety of information. The information included in the parameter configuration is described below.

Among them, parameter configuration includes at least one of the following:

(1) PCI (Physical Cell Identifier, physical cell identifier).

The PCI is a cell identifier. After receiving the PCI, the terminal can determine the indicated cell based on the PCI.

In some embodiments, the PCI is included in the configuration signaling, and the cell is further indicated by the PCI, so that the terminal can determine the cell indicated by the configuration signaling.

The terminal identifier is used to indicate the terminal. In some embodiments, the terminal identity is represented by RNTI (Radio Network Temporary Identity, Wireless Network Temporary Identity), or by other identities, which are not limited in the embodiments of this application.

(3) Timer.

The timer is used for timing. When the timer stops or times out, the terminal needs to perform corresponding operations based on the configuration.

In some embodiments, the timer is a T304 timer (a type of timer). Among them, if the terminal receives the RRC connection reconfiguration message sent by the network device, the timer is started, and the timer is stopped after the terminal completes random access to the new cell, or, if the timer times out, the terminal restores the original cell configuration and Initiate an RRC reestablishment request.

(4) RACH (Random Access Channel, random access channel) resource configuration.

Wherein, the RACH resource configuration indicates random access channel resources. In some embodiments, the RACH resource configuration is used for terminals to perform random access.

(5) Uplink public configuration parameters.

(6) Downlink public configuration parameters.

The downlink public configuration parameter indicates the parameters when the terminal performs downlink transmission, so as to facilitate the terminal to perform downlink transmission.

(7) Ephemeris information.

Among them, the ephemeris information indicates the position of the satellite during operation. In some embodiments, the ephemeris information is also called an ephemeris and is used to record the orbital parameters of the satellite, thereby indicating the position of the satellite.

The number of first cells indicated by the configuration signaling involved in this application varies in different situations. The following describes the case where the number of first cells indicated by the configuration signaling parameter configuration is different.

In some embodiments, when the network device determines the target cell for the terminal to perform cell switching, the network device directly configures the parameter configuration of the target cell for the terminal. That is to say, the first cell indicated by the configuration signaling includes one. It can also be understood that The first cell includes a target cell, which is the cell where the terminal performs cell handover, and the second cell is the serving cell.

In this embodiment of the present application, if the configuration signaling received by the terminal indicates the parameter configuration of the first cell, that is, the first cell indicated by the configuration signaling is the parameter configuration of the target cell when the terminal performs cell handover, and the parameter configuration indicates to the terminal Use all or part of the parameter configuration of the serving cell.

Wherein, the cell currently accessed by the terminal is the serving cell, that is, the terminal knows the parameter configuration of the serving cell, then the network device indicates the parameter configuration of the first cell through configuration signaling, and the parameter configuration of the first cell indicates that the terminal can Use all or part of the parameter configuration of the serving cell.

In other embodiments, the network device configures multiple target cells for cell handover for the terminal. Then, when the terminal determines that cell handover is required, it selects the cell for cell handover from the multiple target cells, and then based on the cell Parameter configuration for cell switching. That is to say, the first cell indicated by the configuration signaling includes multiple target cells, and the multiple target cells can be used for the terminal to perform cell switching. The parameter configuration indication of each target cell in the multiple target cells uses the second All or part of the parameters of the cell are configured, and the second cell may be a serving cell. Alternatively, the second cell is any cell among multiple target cells. Among the multiple target cells configured by the network device for the terminal, there is a target cell configured with complete parameter configuration. The target cell belongs to one of the multiple target cells, that is to say, the complete parameter configuration has been configured. The target cell may serve as a second cell, and other target cells may use all or part of the parameter configurations in the second cell.

In this embodiment of the present application, if the configuration signaling received by the terminal indicates the parameter configuration of multiple target cells included in the first cell, that is, the multiple target cells indicated by the configuration signaling are candidate cells for the terminal to perform cell handover. The parameter configuration of the target cell indicates the use of all or part of the parameter configuration of the serving cell, or indicates the use of all or part of the parameter configuration of any target cell among multiple target cells.

Among them, the parameter configuration of the network device is the terminal configuration including a target cell with complete parameter configuration. This target cell is any one of multiple target cells included in the first cell. This target cell with complete parameter configuration is used as the second cell. cell, and the parameter configuration of the first cell indicated by the parameter configuration of the network device may use all or part of the parameter configuration of the target cell for which the complete parameter configuration has been configured.

It should be noted that in the embodiment of this application, when the network device configures the parameter configurations of multiple target cells for the terminal, the parameter configurations of different target cells can be different. That is to say, the network device performs differentiated configurations on multiple target cells. To implement parameter configuration for different first cells through different configurations.

In the solution provided by the embodiment of this application, the configuration signaling can configure the parameter configuration of at least one cell for the terminal, and the second cell can also select the serving cell or other cells, which expands the types of the second cell and improves flexibility, and It breaks the limitation that network devices need to send parameter configurations to terminals, thereby saving signaling overhead and improving resource utilization.

This application also provides a network device that can use an explicit method or an implicit method to indicate the parameter configuration of the first cell. The explicit method or the implicit method will be described below.

In this embodiment of the present application, the parameter configuration of the first cell indicated by the configuration signaling instructs the terminal to use all or part of the parameter configuration of the second cell, and the network device can indicate the parameters of the first cell in an explicit or implicit manner. Configuration, and the configuration signaling also indicates the parameter configuration of the first cell. Therefore, the embodiment of the present application can also be understood as the parameter configuration of the first cell explicitly or implicitly instructs the terminal to use all or part of the second cell. Parameter configuration.

In some embodiments, the configuration signaling indicates, explicitly or implicitly, that the parameter configuration of the first cell uses all or part of the parameter configuration of the target cell.

In this embodiment of the present application, after receiving the configuration signaling, the terminal can determine according to the configuration signaling whether the network device explicitly or implicitly instructs the parameter configuration of the first cell to use all or part of the parameter configuration of the target cell.

Below, the explicit and implicit methods are explained respectively:

First, the explicit method is to indicate the parameter configuration of the first cell through indication signaling, using all or part of the parameter configuration of the cell indicated by the indication signaling.

In this embodiment of the present application, the indication signaling may indicate a cell. For the configuration signaling received by the terminal, the configuration signaling explicitly indicates the parameter configuration of the first cell using all the cells indicated by the indication signaling. Or some parameter configuration.

The indication signaling includes a cell identifier, and the explicit method is to indicate the parameter configuration of the first cell through the indication signaling using all or part of the parameter configuration of the cell indicated by the cell identifier.

For example, if the cell identifier is PCI, then the terminal determines the indicated cell according to the PCI included in the indication signaling, and then the terminal determines the parameter configuration of the first cell using all or part of the parameter configuration of the cell indicated by the PCI.

In some embodiments, when the parameter configuration does not include the parameter configuration required by the terminal, the parameter configuration required by the terminal uses the corresponding parameter configuration of the second cell.

In the embodiment of this application, if the configuration signaling configures part of the parameter configuration for the first cell of the terminal, the remaining parameter configuration needs to use the corresponding parameter configuration of the second cell, and if the configuration signaling does not configure the first cell of the terminal Parameter configuration, then all parameter configurations of the first cell need to use the parameter configuration of the second cell. In other words, whether the terminal uses all parameter configurations of the second cell depends on the parameter configuration provided by the network device.

For example, the network device configures the parameter configurations of two first cells for the terminal through configuration signaling. The two first cells are the first cell 1 and the first cell 2 respectively, and the network device configures all parameter configurations for the first cell 1, For the first cell 2, the configuration signaling indicates the first cell 1 through the PCI included in the indication signaling, and the parameter configuration of the first cell 2 can use all or part of the parameter configuration of the first cell 1.

Taking the parameter configuration including PCI, terminal identification, timer, RACH resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information as an example, if the parameter configuration of the first cell 1 includes PCI, terminal identification, timer, RACH Resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information. If the parameter configuration of the first cell 2 includes PCI, terminal identification, timer, and RACH resource configuration, but does not include uplink public configuration parameters, downlink public configuration parameters, and ephemeris information, then the uplink public configuration parameters, downlink public configuration parameters, and ephemeris information in the first cell 2 The public configuration parameters and ephemeris information use the uplink public configuration parameters, downlink public configuration parameters and ephemeris information in the first cell 1. Or, if the parameter configuration of the first cell 2 does not include any of PCI, terminal identification, timer, RACH resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information, then the first cell 2 PCI, terminal identification, timer, RACH resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information all use the PCI, terminal identification, timer, RACH resource configuration, uplink public configuration parameters in the first cell 1, Downlink public configuration parameters and ephemeris information.

Second, the implicit method is to indicate by default that the parameter configuration of the first cell uses all or part of the parameter configuration of the serving cell.

In the embodiment of this application, because the implicit mode is the parameter configuration of the cell used by the terminal by default, because the parameter configuration included in the terminal is the parameter configuration of the serving cell, and other cells except the serving cell are all parameters that the terminal is not sure whether it has. Parameter configuration, so this implicit method is that the terminal uses the parameter configuration of the serving cell by default.

The implicit method is stipulated by the communication protocol or configured in other ways, which is not limited by the embodiments of this application.

For example, the network device configures the parameter configurations of two first cells for the terminal through configuration signaling. The two first cells are the first cell 1 and the first cell 2 respectively. Then the parameters of the first cell 1 and the first cell 2 The configuration can be configured using all or part of the parameters of the serving cell.

Taking the parameter configuration including PCI, terminal identification, timer, RACH resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information as an example, if the parameter configuration of the first cell 1 includes PCI, terminal identification, and timer, then The first cell 1 uses the RACH resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information of the serving cell. If the parameter configuration of the first cell 2 includes PCI, terminal identification, timer, and RACH resource configuration, it does not include the uplink public configuration parameters, downlink public configuration parameters, and ephemeris information, then the uplink public configuration parameters, downlink public configuration parameters, and ephemeris information in the first cell 2 use the uplink public configuration parameters, downlink public configuration parameters, and ephemeris in the serving cell. information. Or, if the parameter configuration of the first cell 1 and the first cell 2 does not include any of PCI, terminal identification, timer, RACH resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information, then the The PCI, terminal identification, timer, RACH resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information in the first cell 1 and the first cell 2 all use the PCI, terminal identification, timer, and RACH in the serving cell. Resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information.

In the solution provided by the embodiment of the present application, the configuration signaling can indicate that the parameter configuration of the first cell uses all or part of the parameter configuration of the second cell in an explicit manner or an implicit manner, which expands the indication method of the configuration signaling, and Regardless of the indication method, it breaks the limitation that network equipment needs to send parameter configurations to terminals, thereby saving signaling overhead and improving resource utilization.

It should be noted that the above-mentioned embodiments can be split into new embodiments, or combined with other embodiments to form new embodiments. This application does not limit the combination of embodiments.

Below, the above embodiments will be combined to describe how the network device indicates parameter configuration for the first cell of the terminal through configuration signaling.

In some embodiments, the network device sends configuration signaling to the terminal, the first cell indicated by the configuration signaling includes a target cell, the parameter configuration of the first cell indicates that the terminal uses all or part of the parameter configuration of the serving cell, and, The network device instructs the parameter configuration of the first cell to use all or part of the parameter configuration of the serving cell in an explicit manner or an implicit manner.

After receiving the configuration signaling, the terminal can determine the parameter configuration of a target cell included in the indicated first cell according to the configuration signaling, and determine to use all or part of the parameter configuration of the serving cell according to the parameter configuration indication.

In this embodiment of the present application, the network device determines the target cell for the terminal to perform cell switching, and then the network device directly configures the parameter configuration of the target cell for the terminal. That is to say, the first cell indicated by the configuration signaling includes one, or it can It is understood that the first cell includes a target cell, which is the cell where the terminal performs cell handover, and the second cell is the serving cell.

In some embodiments, the parameter configuration includes at least one of the following: PCI, terminal identification, timer, RACH resource configuration, uplink public configuration parameters, downlink public configuration parameters, and ephemeris information.

For example, if the network device explicitly indicates that the parameter configuration of the first cell uses all or part of the parameter configuration of the serving cell, the serving cell is indicated through the indication signaling in the configuration signaling, and the terminal receives the configuration signaling. Then, the serving cell indicated by the indication signaling can be determined.

It should be noted that the explicit method in the embodiment of the present application is similar to the explicit method in the above embodiment, and will not be described again.

For another example, if the network device indicates in an implicit manner that the parameter configuration of the first cell uses all or part of the parameter configuration of the serving cell, then it suffices to instruct the terminal to use all or part of the parameter configuration of the serving cell by default through configuration signaling.

It should be noted that the implicit method in the embodiment of the present application is similar to the implicit method in the above embodiment, and will not be described again.

In other embodiments, the network device sends configuration signaling to the terminal. The first cell indicated by the configuration signaling includes multiple target cells, and the parameter configuration of the first cell instructs the terminal to use all or part of the parameter configuration of the second cell. , the second cell can be a serving cell. Alternatively, the second cell is any cell among multiple target cells. Among the multiple target cells configured by the network device for the terminal, there is a target cell configured with complete parameter configuration. The target cell belongs to one of the multiple target cells, that is to say, the complete parameter configuration has been configured. The target cell may serve as a second cell, and other target cells may use all or part of the parameter configurations in the second cell.

Furthermore, the network device explicitly indicates that the parameter configuration of the first cell uses all or part of the parameter configuration of the cell indicated by the indication signaling.

For example, if the network device explicitly indicates that the parameter configuration of the first cell uses all or part of the parameter configuration of the serving cell, and then indicates the second cell through the indication signaling in the configuration signaling, the terminal receives the configuration signaling. Then, the second cell indicated by the indication signaling can be determined.

Figure 5 shows a flow chart of another parameter configuration method provided by an exemplary embodiment of the present application. The exemplary method can be applied to the terminal shown in Figure 1. The method includes at least part of the following content:

In other embodiments, the network device configures multiple target cells for cell handover for the terminal. Then, when the terminal determines that cell handover is required, it selects the cell for cell handover from the multiple target cells, and then based on the cell Parameter configuration for cell switching. That is to say, the first cell indicated by the configuration signaling includes multiple target cells, and the multiple target cells can be used for the terminal to perform cell switching, and the parameter configuration indication of each target cell in the multiple target cells uses the third cell.
