Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a satellite communication processing method, a device, a network device, and a terminal.

Background

The satellite communication modes mainly comprise a transparent forwarding mode and an on-board processing mode.

Referring to fig. 1, an embodiment of the present application provides a satellite communication processing method, which is applied to a network device, and includes:

step 101, indicating satellite communication mode of a target cell by an explicit and/or implicit mode; wherein, the satellite communication mode is: transparent forwarding mode or satellite processing mode.

In the step, the target cell is a serving cell of the terminal, or the target cell is a neighboring cell of the serving cell of the terminal.

It should be noted that, the transparent forwarding mode and the satellite processing mode have different parameter configurations of time-frequency synchronization and inter-satellite switching, and after the satellites in the two satellite communication modes, namely the transparent forwarding mode and the satellite processing mode, are mixed and networked, if the terminal cannot identify the working mode of the satellite cell, the terminal cannot select a proper parameter configuration to perform network switching or network access.

Wherein the network device indicates the timing of the satellite communication mode of the target cell includes, but is not limited to: an initial access phase, after entering an RRC connected state, or before a network handover.

Optionally, for the satellite processing mode, the network device refers to a satellite base station; for transparent forwarding mode, the network device refers to a gateway station including a base station on the ground.

In the above embodiments, the network device indicates the satellite communication mode of the target cell to the terminal by explicit and/or implicit means. Thus, after the satellites in the two communication modes are mixed and networked, the terminal can identify the satellite communication mode through the explicit or implicit indication of the network equipment, so that the communication is normal in the mixed networking.

In one embodiment, indicating the satellite communication mode of the target cell by explicit means includes:

In this embodiment, the first indication information is carried by newly creating RRC signaling or adding 1 bit (bit) to existing RRC signaling, and is used to indicate the satellite communication mode. Specifically, an operation mode indication identifier (i.e., first indication information) may be added to parameters such as RRC reconfiguration (rrcrecon configuration), neighbor cell list, etc., where "0" indicates a transparent forwarding mode and "1" indicates a satellite processing mode.

In an embodiment, the indicating, by an explicit manner, the satellite communication mode of the target cell includes:

For example, 1bit is added to the MIB message to carry second indication information for indicating a satellite communication mode; the second indication information is "0" indicating a transparent forwarding mode, and the second indication information is "1" indicating a satellite processing mode.

For example, newly-built SIB message or 1bit added in the SIB message carries second indication information for indicating satellite communication mode; the second indication information is "0" indicating a transparent forwarding mode, and the second indication information is "1" indicating a satellite processing mode.

In an embodiment, the indicating, by way of implicit indication, the satellite communication mode of the target cell includes:

The cell ID may be defined as a physical cell identity (Physical Cell Identities, PCI) ID, which is determined by a primary synchronization signal (Primary Synchronization Signal, PSS) sequence ID and a secondary synchronization signal (Secondary Synchronization Signal, SSS) sequence ID. Specifically, n_id (cell) =3×n_id (SSS) +n_id (PSS); where n_id (cell) is a cell ID, n_id (SSS) represents an ID of an SSS sequence, and n_id (PSS) represents an ID of a PSS sequence.

As one implementation, the first correspondence relationship includes:

when the cell ID of a target cell is an odd number, the satellite communication mode of the target cell is a transparent forwarding mode; when the cell ID of the target cell is even, the satellite communication mode of the target cell is a satellite processing mode.

For example, the fifth generation mobile communication technology (5th Generation Mobile Communication Technology,5G) has 1008 PCI IDs of a New Radio (NR), an odd ID indicates a transparent forwarding mode, and an even ID indicates a satellite processing mode.

As another implementation manner, the first correspondence relationship includes:

when the cell ID of a target cell can divide N completely, the satellite communication mode of the target cell is a transparent forwarding mode; when the cell ID of a target cell cannot divide N completely, the satellite communication mode of the target cell is a satellite processing mode; wherein N is a positive integer greater than 2.

For example, N is 5, PCI idmod5=0 represents transparent forwarding mode, and PCI idmod5+.0 represents satellite processing mode; or, N is 19, PCI idmod19=0 represents transparent forwarding mode, and PCI idmod19+.0 represents satellite processing mode; where mod is the modulo operator.

In this embodiment, the terminal may identify the satellite communication mode of the target cell based on the first correspondence and the cell ID of the target cell by predefining the first correspondence between the cell ID and the satellite communication mode.

For example, for the S band, the first operating band is: uplink 1980-1990MHz, downlink 2170-2180MHz; the second working frequency band is as follows: uplink 2000-2010MHz, downlink 2190-2200MHz. The first working frequency band corresponds to the transparent forwarding mode, and the second working frequency band corresponds to the satellite processing mode.

In this embodiment, the second correspondence between the working frequency band of the cell and the satellite communication mode may be predefined, so that the terminal may identify the satellite communication mode of the target cell based on the second correspondence and the working frequency band of the target cell.

For example, the network device configures a value of a common timing advance (Common Timing Advance, CTA) to be 0, indicating satellite processing mode; and when the network equipment configures the K-Mac parameter to be 0, indicating a transparent forwarding mode.

For example, when the values of the network device configuration CTA and K-Mac parameters are 0, the satellite processing mode is indicated; the network device configures at least one of the CTA and the K-Mac to be other than 0, indicating a transparent forwarding mode.

The K-Mac parameter is used for indicating scheduling offset provided by the network when the downlink frame time sequence and the uplink frame time sequence of the gNB side are not aligned. The K-mac parameter is in units of the number of slots for a given subcarrier spacing. The K-Mac parameters require the UE to operate and assume according to the downlink configuration indicated by a media access Control (Medium Access Control, mac) Control Element (CE) command in the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH). In particular, when the network does not provide the UE with the value of the K-Mac parameter, the UE assumes K-mac=0.

For example, the network device configures CTA, first derivative of common timing advance (CTADrift), and second derivative of common timing advance (CTADrift variance) to be 0, indicating satellite processing mode; at least one parameter of CTA, CTA drift and CTA drift Variance configured by the network device is not 0, indicating transparent forwarding mode.

For the above embodiment, as in fig. 2, the flow of the satellite communication processing method includes: the network side indicates a satellite communication mode and judges whether the satellite communication mode is indicated explicitly or not; when determining to explicitly indicate the satellite communication mode, the network side indicates the satellite communication mode through MIB, SIB and RRC signaling; when determining the implicit indication satellite communication mode, the network side indicates the satellite communication mode through a cell ID, a cell working frequency band or a parameter for calculating and calculating the timing advance TA.

Referring to fig. 3, an embodiment of the present application provides a satellite communication processing method, which is applied to a terminal, and includes:

step 201, acquiring a satellite communication mode of a target cell indicated by a network device in an explicit and/or implicit mode; wherein, the satellite communication mode is: transparent forwarding mode or satellite processing mode.

The target cell is a serving cell of the terminal, or the target cell is a neighboring cell of the serving cell of the terminal.

In this way, the terminal can select appropriate parameter configuration to perform network switching or network access according to the identified satellite communication mode. For example, in the transparent forwarding mode, the terminal will use the feeder link delay between the satellite and the ground gateway station when calculating the TA compensation, while the feeder link delay will not be needed in the satellite processing mode; or when the terminal initiates the cell switching of different satellite communication modes, the satellite communication mode of the target cell is obtained, which is helpful for the terminal to configure related parameters and complete the cell switching.

In an embodiment, the acquiring the satellite communication mode of the target cell indicated by the network device through an explicit mode includes:

In this embodiment, the network device carries the first indication information by newly creating RRC signaling or adding 1 bit (bit) to the existing RRC signaling, so as to indicate the satellite communication mode. Specifically, an operation mode indication identifier (i.e., first indication information) may be added to parameters such as RRC reconfiguration (rrcrecon configuration), neighbor cell list, etc., where "0" indicates a transparent forwarding mode and "1" indicates a satellite processing mode. The terminal can determine the satellite communication mode of the target cell based on the working mode indication marks in the parameters such as RRCRECONfigure, neighbor cell list and the like.

For example, 1bit is added to the MIB message to carry second indication information for indicating a satellite communication mode; the second indication information is "0" indicating a transparent forwarding mode, and the second indication information is "1" indicating a satellite processing mode. Thus, the terminal can determine the satellite communication mode of the target cell based on the second indication information carried in the MIB message.

For example, newly-built SIB message or 1bit added in the SIB message carries second indication information for indicating satellite communication mode; the second indication information is "0" indicating a transparent forwarding mode, and the second indication information is "1" indicating a satellite processing mode. Thus, the terminal can determine the satellite communication mode of the target cell based on the second indication information carried in the SIB message.

In an embodiment, the acquiring the satellite communication mode of the target cell indicated by the network device in a hidden manner includes:

As one implementation, the first correspondence relationship includes:

In this embodiment, the terminal may identify the satellite communication mode of the target cell according to the first correspondence and the cell ID of the target cell.

In this embodiment, the terminal may identify the satellite communication mode of the target cell according to the working frequency band of the target cell and the second correspondence between the working frequency band of the cell and the satellite communication mode.

For example, if the value of the public timing advance (Common Timing Advance, CTA) configured at the network device is 0, determining that the satellite communication mode of the target cell is a satellite processing mode; and when the K-Mac parameter configured by the network equipment is 0, determining that the satellite communication mode of the target cell is a transparent forwarding mode.

For example, when the values of CTA and K-Mac configured by the network device are both 0, determining that the satellite communication mode of the target cell is a satellite processing mode; and if at least one parameter in CTA and K-Mac configured by the network equipment is not 0, determining that the satellite communication mode of the target cell is a transparent forwarding mode.

For example, if CTA configured at the network device, a first derivative of a common timing advance (CTADrift), and a second derivative of a common timing advance (CTADrift variance) are all 0, determining that the satellite communication mode of the target cell is a satellite processing mode; and if at least one parameter in CTA, CTA drift and CTA drift variance configured by the network equipment is not 0, determining that the satellite communication mode of the target cell is a transparent forwarding mode.

In this embodiment, the terminal can identify the satellite communication mode of the target cell based on at least one target parameter for calculating the timing advance TA.
