When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] It is understood that in this disclosure, "multiple" refers to two or more, and other quantifiers are similar. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

[0043] It should be understood that although the terms first, second, third, etc., may be used to describe various information in the embodiments of this application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the words "if" and "suppose" as used herein can be interpreted as "when," "when," or "in response to a determination."

[0044] To facilitate understanding, the terminology used in this application will be introduced first.

[0045] 1. Wireless Resource Management (RRM)

[0046] RRM can provide quality of service assurance for wireless user terminals within a network under limited bandwidth conditions. Its basic premise is to maximize the utilization of wireless spectrum, prevent network congestion, and maintain the smallest possible signaling load by flexibly allocating and dynamically adjusting the available resources of the wireless transmission part and the network under conditions such as uneven distribution of network traffic and fluctuations in channel characteristics due to channel attenuation and interference.

[0047] 2. Wireless Link Detection (RLM)

[0048] The behavior of a terminal device monitoring the downlink radio link quality of the primary cell in order to indicate the asynchronous / synchronous state to higher layers is called RLM (Remote Link Monitoring). The resources used to monitor the radio link can be single-sideband (SSB) signals, Channel State Information Reference Signals (CSI-RS), or both.

[0049] 3. Residential area

[0050] In a cellular mobile communication system, a cell is the area covered by one or a portion of a base station (fan antenna), within which mobile stations can reliably communicate with the base station via a wireless channel.

[0051] In a satellite communication system, a cell is the area covered by radio waves emitted by one of the satellites, within which radio communication stations can use the satellite as a relay to conduct communication.

[0052] To better understand the method for determining the satellite type of a cell disclosed in the embodiments of this application, the communication system to which the embodiments of this application are applicable is described below.

For example, long term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems, etc.

[0055] The network device 101 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This application does not limit the specific technology or device form used in the network device. The network device provided in this embodiment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0056] In this application embodiment, the terminal device 102 is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal device.

[0057] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0058] It is understood that the multiple solutions in the embodiments of this application can be implemented individually or in combination, and this application does not limit them in this regard.

[0059] The method and apparatus for determining the satellite type of a cell provided in this application will be described in detail below with reference to the accompanying drawings.

[0060] Figure 2 This is a flowchart illustrating a method for determining the satellite type of a cell according to an embodiment of this application. This method is applied to a terminal device, such as... Figure 2 As shown, the method includes:

[0061] S201, Obtain instruction information.

[0062] The indication information is used to determine the satellite type of the serving cell and neighboring cells where the terminal device is located.

[0063] Optionally, the indication information can simultaneously indicate the satellite type of the serving cell and the neighboring cells, or it can indicate the satellite type of the serving cell and the neighboring cells separately.

[0064] Optionally, the indication information can be sent by the serving cell, or by the serving cell and neighboring cells respectively.

[0065] In some implementations, the indication information is sent by the serving cell, and the indication information sent by the serving cell includes the satellite types of the serving cell and neighboring cells.

[0066] In other implementations, the indication information is sent separately by the serving cell and neighboring cells. The indication information sent by the serving cell includes the satellite type of the serving cell, and the indication information sent by the neighboring cells includes the satellite type of the neighboring cells.

[0067] Optionally, the serving cell can send different indication information based on the connection status of the terminal device. For example, when the terminal device is in an idle state, it can receive system information block (SIB) messages broadcast by the serving cell; when the terminal device is in a connected state, it can receive measurement objects sent by the serving cell. That is, the serving cell can send indication information through the IE "MeasObjectNR".

[0068] S202, based on the instruction information, determine the satellite type of the serving cell and neighboring cells where the terminal device is located.

[0069] Optionally, the indication information includes a mapping relationship between different cells and satellite types. Based on this mapping relationship, the satellite types of the serving cell and neighboring cells where the terminal device is located can be determined. In some implementations, different cells include the serving cell and / or neighboring cells. In other implementations, different cells may include cells under the carrier of the serving cell and / or cells under the carrier of the neighboring cells.

[0070] Optionally, the satellite types include the following: geostationary earth orbiting (GEO), medium earth orbiting (MEO), low earth orbiting (LEO), and high altitude platform station (HAPS).

[0071] In some implementations, the satellite type of the serving cell and the satellite type of the neighboring cells can be the same. For example, the satellite type of the serving cell can be GEO, and the satellite type of the neighboring cells can also be GEO.

[0072] In other implementations, the satellite type of the serving cell and the satellite type of the neighboring cells can be different. For example, the satellite type of the serving cell can be GEO, and the satellite type of the neighboring cells can be MEO.

[0073] This application provides a method for determining the satellite type of a cell. By using indication information, the satellite types of the serving cell and neighboring cells where the terminal device is located are obtained, and the serving cell and neighboring cells can be matched with their respective satellite types based on their respective satellite types.

[0074] Optionally, RRM and / or RLM measurement requirements can be determined based on satellite type. For example, due to the different orbital altitudes of different satellite types, some types of satellites will experience relative movement with the ground, making it impossible to reuse the timing requirements of the ground system. In such cases, the respective RRM and / or RLM measurement requirements can be determined based on the satellite's orbital altitude.

[0075] In this application, after determining the satellite types of the serving cell and neighboring cells, the terminal equipment can determine the measurement requirements of the serving cell and neighboring cells according to the satellite types, effectively solving the problem that the RRM and RLM requirements are different due to different satellite orbits.

[0076] Figure 3 This is a flowchart illustrating a method for determining the satellite type of a cell according to an embodiment of this application. This method is applied to a terminal device, such as... Figure 3 As shown, the method includes:

[0077] S301, Receive first indication information sent by the serving cell, wherein the first indication information includes the satellite types of the serving cell and neighboring cells.

[0078] The first instruction information is the instruction information in the aforementioned embodiments.

[0079] In response to the terminal device being in an idle state, the serving cell broadcasts a first SIB message to the terminal device, and the terminal device can receive the first SIB message accordingly. The first SIB message is first indication information, and includes the mapping relationship between different cells and satellite types.

[0080] In response to the terminal device being in a connected state, the serving cell sends a first measurement object to the terminal device, and the terminal device can receive the first measurement object accordingly. The first measurement object is first indication information, which includes the mapping relationship between different cells and satellite types.

[0081] In some implementations, different cells include the serving cell and / or neighboring cells. In other implementations, different cells may include cells on the carrier of the serving cell and / or cells on the carrier of neighboring cells.

[0082] S302, based on the first instruction information, determine the satellite type of the serving cell and neighboring cells where the terminal device is located.

[0083] Based on the mapping relationship between different cells and satellite types in the first instruction information, the satellite types of the serving cell and neighboring cells where the terminal device is located are determined.

[0084] In some implementations, the terminal device simultaneously receives a first measurement object sent by the serving cell and a first SIB message broadcast by the serving cell. In response to the discrepancy between the satellite type of the target cell indicated by the first measurement object and the satellite type of the target cell indicated by the first SIB message, the satellite type of the target cell indicated by the first measurement object is determined as the final satellite type of the target cell.

[0085] This application provides a method for determining the satellite type of a cell, in which the serving cell directly indicates the satellite types of the serving cell and neighboring cells, enabling terminal equipment to determine the corresponding measurement requirements based on the satellite types.

[0086] Figure 4 This is a flowchart illustrating a method for determining the satellite type of a cell according to an embodiment of this application. This method is applied to a terminal device, such as... Figure 4 As shown, the method includes:

[0087] S401, Receive second indication information sent by the serving cell, wherein the second indication information is used to indicate the satellite type of the serving cell.

[0088] The second instruction information is the instruction information in the aforementioned embodiments.

[0089] In response to the terminal device being in an idle state, the serving cell broadcasts a second SIB message to the terminal device, and the terminal device can receive the second SIB message accordingly. The second SIB message is a second indication information, which includes the mapping relationship between different cells and satellite types under the carrier of the serving cell.

[0090] In response to the terminal device being in a connected state, the serving cell sends a second measurement object to the terminal device, and the terminal device can receive the second measurement object accordingly. The second measurement object is second indication information, which includes the mapping relationship between different cells and satellite types under the carrier of the serving cell.

[0091] S402, receive third indication information sent by a neighboring cell, wherein the third indication information is used to indicate the satellite type of the neighboring cell.

[0092] The third instruction information is the instruction information in the aforementioned embodiments.

[0093] Receive the third SIB message broadcast by the neighboring cell on the carrier where the neighboring cell is located. The third SIB message is the third indication information and includes the mapping relationship between different cells and satellite types under the carrier where the neighboring cell is located.

[0094] S403, based on the second and third instruction information, determine the satellite type of the serving cell and neighboring cells where the terminal device is located.

[0095] The satellite type of the serving cell is determined based on the mapping relationship in the second instruction information.

[0096] In some implementations, the terminal device simultaneously receives a second measurement object sent by the serving cell and a second SIB message broadcast by the serving cell. In response to the fact that the satellite type corresponding to the serving cell indicated by the second measurement object is inconsistent with the satellite type corresponding to the serving cell indicated by the second SIB message, the satellite type corresponding to the serving cell indicated by the second measurement object is determined as the final satellite type of the serving cell.

[0097] Based on the mapping relationship in the third instruction information, determine the satellite type of the neighboring cell.

[0098] This application provides a method for determining the satellite type of a cell, wherein the serving cell and neighboring cells each indicate the satellite type of the cell, so that the terminal device can determine the corresponding measurement requirements based on the satellite type.

[0099] Figure 5 This is a flowchart illustrating a method for determining the satellite type of a cell according to an embodiment of this application. This method is applied to a terminal device, such as... Figure 5 As shown, the method includes:

[0101] S502, based on the instruction information, determines the satellite type of the serving cell and neighboring cells where the terminal device is located.

[0102] For details on the specific implementation of steps S501 and S502, please refer to the relevant descriptions in the embodiments of this disclosure, which will not be repeated here.

[0103] S503, based on the satellite type of the serving cell and neighboring cells, performs Radio Resource Management (RRM) requirements and / or Radio Link Monitoring (RLM) requirements on the serving cell and neighboring cells.

[0104] Optionally, GEO satellites correspond to Type I RRM and RLM requirements, MEO satellites to Type II RRM and RLM requirements, LEO satellites to Type III RRM and RLM requirements, and HAPS satellites to Type IV RRM and RLM requirements. Based on the satellite type of the serving cell and neighboring cells, the RRM and RLM requirements for the serving cell and neighboring cells are determined, and measurements are performed on the serving cell and neighboring cells according to the requirements.

[0105] Determine the first RRM requirement and / or RLM requirement corresponding to the satellite type of the serving cell, and perform RRM and / or RLM measurements on the serving cell in accordance with the first RRM requirement and RLM requirement.

[0106] Determine the second RRM requirement and / or RLM requirement corresponding to the satellite type of the neighboring cell, and perform RRM and RLM measurements on the neighboring cell in accordance with the second RRM requirement and RLM requirement.

[0107] For example, if the serving cell's satellite type is MEO, the first RRM requirement and / or RLM requirement is determined as the second type of RRM and RLM requirement, and RRM and / or RLM measurements are performed on the serving cell according to the second type of RRM and RLM requirement. If the neighboring cell's satellite type is LEO, the second RRM requirement and / or RLM requirement is determined as the third type of RRM and RLM requirement, and RRM and / or RLM measurements are performed on the serving cell according to the third type of RRM and RLM requirement.

[0108] The RRM and RLM measurement requirements include at least one of the following: cell mobility requirements in idle and inactive states, cell mobility requirements in connected states, timing requirements, RLM requirements, interruption requirements, beam failure detection (BFD) evaluation requirements, candidate beam detection (CBD) evaluation requirements, and RRM requirements.

[0109] The RRM and RLM measurement requirements are any combination of the above requirements, such as timing requirements, RLM requirements, interruption requirements, or BFD evaluation requirements, CBD evaluation requirements, and RRM requirements. Furthermore, the RRM and RLM measurement requirements include, but are not limited to, the requirements described above.

[0110] This application provides a method for determining the satellite type of a cell, enabling terminal devices to determine RRM and RLM measurement requirements based on the satellite type, effectively solving the problem that RRM and RLM requirements differ due to different satellite orbits.
