[0032] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0033] The terms "first", "second", etc. of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of one type, and the number of objects is not limited, for example, the first object can be one or more. In addition, "or" in the present application represents at least one of the connected objects. For example, "A or B" covers three schemes, namely, Scheme 1: including A but not including B; Scheme 2: including B but not including A; Scheme 3: including both A and B. The character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0034] The term "indication" in this application can be a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, operations to be performed, or request results in the sent indication; an indirect indication can be understood as the receiver determining the corresponding information according to the indication sent by the sender, or making a judgment and determining the operation to be performed or the request result according to the judgment result.

[0035] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) or other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following descriptions, but these technologies can also be applied to systems other than NR system applications, such as the 6th generation (6 th Generation, 6G) communication system.

[0036] In order to facilitate understanding of the embodiments of the present application, the following technical points are first introduced below:

[0037] 1. About Earth fixed cells and Earth moving cells.

[0038] As low-orbit satellites move in the sky over time, there are two types of cell deployments:

[0039] Ground-moving cells: cells (ground coverage areas) move over time.

[0040] Quasi-earth-fixed cell: A cell covers one geographic area for a period of time and a different geographic area for another period of time (for example, a satellite can achieve this scenario by generating a steerable beam)

[0041] In addition, there is another cell type, as follows:

[0042] Fixed cell: A cell that covers the same geographical area all the time (e.g. cell coverage provided by geostationary satellites)

[0043] 2. About location-based CHO / location-based measurement event.

[0044] Since the satellite is far from the ground, the neighboring cell reference signal received power (RSRP) or reference signal received quality (RSRQ) or interference and noise ratio (SINR) measured by the terminal and the RSRP or RSRQ or SINR of the serving cell may be very similar, and it is inaccurate to rely solely on the execution of conditional handover (CHO) triggered by signal strength or signal quality. Therefore, the CHO trigger event based on distance is introduced in the related art.

[0045] Similarly, measurement report triggering will also have the same problem, so related technologies also introduce distance-based measurement report events.

It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

[0048] The network side device 22 may include an access network device or a core network device, wherein the access network device may also be referred to as a radio access network device, a radio access network (RAN), a radio access network function, or a radio access network unit.

[0050] The communication processing method, apparatus, communication device and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0051] See also Figure 3 , an embodiment of the present application provides a communication processing method, which is executed by a terminal, and the specific steps are as follows:

[0052] Step 301: The terminal obtains a reference position of a target cell according to at least one of the first information and the satellite auxiliary information for accessing the NTN;

[0053] Wherein, the first information is used to obtain the reference position of the target cell;

[0054] The target cell includes at least one of a first candidate cell, a serving cell, and a neighboring cell, wherein the first candidate cell is a candidate cell for conditional switching, and the neighboring cell is a neighboring cell of the serving cell.

[0055] In one implementation of the present application, the terminal is in a connected state.

[0056] For example, a terminal in a connected state can estimate the reference position of the target cell based on the reference position, epochTime and ephemeris information provided by the first information. For another example, the terminal in a connected state can ignore the reference position provided by the first information, and the terminal estimates the reference position of the target cell based on the reference position, epochTime and ephemeris information provided by the satellite auxiliary information used to access the NTN. For another example, the terminal in a connected state can estimate the reference position of the target cell based on the reference position provided by the first information, and the epochTime and ephemeris information provided by the satellite auxiliary information used to access the NTN. In this way, the terminal can autonomously and quickly obtain the reference position of the target cell, thereby saving the signaling overhead caused by the change of the reference position of the target cell.

[0057] In one embodiment of the present application, the satellite assistance information for accessing the NTN is carried by a system message, for example, the system message may be a system information block (SIB) 19; the first information is carried by dedicated signaling, for example, the dedicated signaling may be a radio resource control reconfiguration (RRC Reconfiguration) signaling.

[0058] It should be noted that, in this embodiment, no specific limitation is imposed on system messages and dedicated signaling.

[0059] In an implementation manner of the present application, the first information includes second information, and the second information can be used for the terminal to evaluate and execute CHO. The second information can also be referred to as location-based CHO-related configuration.

[0060] The second information includes at least one of the following:

[0061] (1) a first reference position, where the first reference position is a reference position of the serving cell at a first time;

[0062] It can be understood that the reference location of the serving cell at the first time can be represented by the movingReferenceLocation field in the protocol, that is, the reference location of the serving cell of an NTN Earth moving system at a reference time (Reference location of the serving cell of an NTN Earth moving systemat a time reference).

[0063] (2) the first time;

[0064] Optionally, at least one of the following is met for the first time:

[0065] (a) the first time and the ephemeris information of the serving cell are used by the terminal to obtain a reference position of the serving cell;

[0066] (b) the time unit of the first time is one of the following: frame, subframe, time slot, symbol, second, millisecond, microsecond;

[0067] If the first time is represented by frames and / or subframes, the terminal considers that the first time (represented by the system frame number (SFN) or subframe number in this field) is one of the following: the field SFN represents the current SFN or the next upcoming SFN after the frame indicating the first time is received; the frame closest to the frame indicating the first time is received.

[0068] (c) the first time is an absolute time, such as Universal Time Coordinated (UTC);

[0069] (d) The timing reference of the first time is the serving cell, that is, the frame number or subframe number indicated in the first time refers to the frame number or subframe number of the serving cell.

[0075] (a) the second time and the ephemeris information of the first candidate cell are used by the terminal to obtain a reference position of the first candidate cell;

[0076] (b) the time unit of the second time is one of the following: frame, subframe, time slot, symbol, second, millisecond, microsecond;

[0077] If the second time is represented by frames and / or subframes, the terminal considers that the second time (represented by the SFN or subframe number in this field) is one of the following: the field SFN represents the current SFN or the next upcoming SFN after the frame in which the message indicating the second time is received; the frame closest to the frame in which the message indicating the second time is received.

[0078] (c) the second time is an absolute time, such as UTC;

[0079] (d) The timing reference of the second time is one of the following: the serving cell, that is, the frame number or subframe number indicated in the second time refers to the frame number or subframe number of the serving cell; the first candidate cell, that is, the frame number or subframe number indicated in the second time refers to the frame number or subframe number of the first candidate cell.

[0083] Optionally, the second information may not directly carry the first indication, but the above content indicated by the first indication may be implicitly indicated through other information in the second information. For example, when the second information does not include the first indication, if the second information includes the ephemeris information of the first time and / or the serving cell, it means that the terminal needs to estimate the reference position of the serving cell, that is, the ephemeris information of the first time or the serving cell may implicitly indicate the above content indicated by the first indication.

[0086] Optionally, the second information may not directly carry the type of the serving cell, but may implicitly indicate the type of the serving cell through other information in the second information or satellite assistance information used to access the NTN. For example, if the second information does not include the type of the serving cell, if the second information includes the ephemeris information of the first time or the serving cell, it indicates that the type of the serving cell is an earth-moving cell; for another example, if the satellite assistance information used to access the NTN includes a reference location-r17 (referenceLocation-r17), it indicates that the type of the serving cell is a quasi-earth-fixed cell; for another example, if the satellite assistance information used to access the NTN includes the reference location of the serving cell in the epochTime of the serving cell, it indicates that the type of the serving cell is an earth-moving cell.
