[0051] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.
[0052] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.
[0053] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.
[0054] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0055] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0056] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0057] For TN scenarios, a joint channel estimation technology solution is introduced to improve the coverage performance of PUSCH (Physical Uplink Share Channel) and PUCCH (Physical Uplink Control Chanel). To enable joint channel estimation, the terminal needs to perform DMRS binding.
[0058] The premise of DMRS binding is that the terminal can maintain power consistency and phase continuity within a certain period of time. The terminal reports the maximum duration for which power consistency and phase continuity can be maintained; the base station configures the nominal TDW length (nominal Time Domain Window length) based on the terminal's report.
[0059] For example, a nominal time window is composed of one or more actual time windows. If no event occurs in a nominal time window, a nominal time window is composed of one actual time window; if an event occurs, a nominal time window is composed of multiple actual time windows. The terminal requires to maintain power consistency and phase continuity in an actual time window.
[0060] For NTN scenarios, 3GPP Rel-18 enhances DMRS bundling technology. Compared with TN scenarios, it is more difficult to maintain phase continuity in NTN scenarios, and the terminal needs to pre-compensate TA and phase.
[0061] However, pre-compensation will affect the continuity of the phase. If pre-compensation is performed within an actual window, the terminal will not be able to maintain phase continuity. As a result, the terminal cannot perform DMRS binding within the actual window, and the base station cannot perform joint channel estimation within the actual window. Therefore, the Rel-17 DMRS binding technology cannot be directly applied to the NTN scenario.
[0062] In view of the above technical problems, the present disclosure proposes a coverage enhancement method, in which the terminal considers the influence of pre-compensation information when reporting the maximum duration that can maintain power consistency and phase continuity. In this way, the problem of using DMRS bundling technology in NTN scenarios is solved, so that DMRS bundling technology can be applied to NTN scenarios, improving NTN coverage performance.
[0063] For example, the technical solution of the present disclosure can be implemented through the following embodiments.
[0064] Figure 1 A flow chart showing some embodiments of the communication method on the base station side of the present disclosure.
[0065] like Figure 1 As shown, in step 110, a first time window is configured according to the maximum duration for the terminal to maintain power consistency and phase continuity reported by the terminal. The maximum duration is determined according to relevant information of at least one of phase pre-compensation or TA pre-compensation. For example, the length of the first time window is less than or equal to the maximum duration.
[0066] In some embodiments, the first time window is configured according to the maximum duration corresponding to the type of the NTN platform reported by the terminal. Different types of NTN platforms correspond to different maximum durations.
[0067] For example, the terminal reports different maximum durations for maintaining power consistency and phase continuity after considering TA pre-compensation and phase pre-compensation for different types of NTN platforms, such as LEO (Low Earth Orbit), MEO (Middle Earth Orbit), GEO (Geostationary Transfer Orbit), etc.
[0068] In step 120, the relevant information of the first time window is sent to the terminal so that the terminal determines a second time window for transmitting data according to the relevant information of the first time window. The terminal maintains power consistency and phase continuity in the second time window.
[0069] For example, the first time window comprises a nominal time window and the second time window comprises an actual time window.
[0070] In some embodiments, the second time window is determined based on relevant information of the first time window and whether an event occurs.
[0071] For example, when no event occurs, the first time window includes one second time window; when an event occurs, the first time window includes multiple second time windows.
[0072] In some embodiments, when the first time window is configured according to the relevant information of the first precompensation, signaling is sent to the terminal so that the terminal performs the second precompensation according to the signaling. The first precompensation includes phase precompensation or TA precompensation, the second precompensation includes phase precompensation or TA precompensation, and the first precompensation is different from the second precompensation.
[0073] For example, the second pre-compensation is performed after the terminal receives the signaling and the current second time window ends.
[0074] For example, when the terminal reports the maximum duration for maintaining power consistency and phase continuity, phase pre-compensation is considered but TA pre-compensation is not considered; the base station configures a first time window according to the report of the terminal, and the length of the first time window is less than or equal to the maximum duration reported by the terminal; the base station sends a signaling to instruct the terminal to perform TA pre-compensation; after the terminal receives the TA pre-compensation instruction from the base station, when the current second time window ends, the terminal performs TA pre-compensation and opens a new second time window; the terminal maintains power consistency and phase continuity within the actual window.
[0075] In this way, since the maximum duration reported by the terminal has taken into account the impact of phase precompensation, the base station does not need to indicate to the terminal when to perform phase precompensation, but only needs to indicate to the terminal when to perform TA precompensation, thereby avoiding the impact of TA precompensation.
[0076] For example, when the terminal reports the maximum duration for maintaining power consistency and phase continuity, TA pre-compensation is considered but phase pre-compensation is not considered; the base station configures a first time window according to the report of the terminal, and the window length is less than or equal to the terminal report; the base station sends a signaling to instruct the terminal to perform phase pre-compensation; after the terminal receives the phase pre-compensation instruction from the base station, when the current second time window ends, the terminal performs phase pre-compensation and opens a new second time window; the terminal maintains power consistency and phase continuity within the actual window; the base station performs joint channel estimation within each second time window.
[0077] In this way, since the maximum duration reported by the terminal has taken into account the impact of TA precompensation, the base station does not need to indicate to the terminal when to perform TA precompensation, but only needs to indicate to the terminal when to perform phase precompensation, thereby avoiding the impact of phase precompensation.
[0078] For example, the terminal reports different maximum durations for maintaining power consistency and phase continuity after considering TA pre-compensation and phase pre-compensation for different NTN platform types (such as LEO, MEO, GEO, etc.); the base station configures the first time window and the NTN platform type according to the report of the terminal, and configures the length of the first time window, and the length of the first time window is less than or equal to the maximum duration reported by the terminal for the NTN platform type; the terminal determines the second time window according to the configuration of the base station and whether an event occurs, and the terminal maintains power consistency and phase continuity within the actual window; the base station performs joint channel estimation in each second time window.
[0079] In this way, since the maximum duration reported by the terminal has taken into account the effects of TA precompensation and phase precompensation, the base station does not need to indicate to the terminal when to perform TA precompensation and phase precompensation (ie, no signaling is required), thereby avoiding the effects of phase precompensation.
[0080] In the above embodiment, the terminal can maintain power consistency and phase continuity within the actual window and has the conditions for DMRS binding; the terminal can perform joint channel estimation through DMRS binding in the NTN scenario, thereby improving the NTN coverage performance.
[0081] In some embodiments, in step 130, joint channel estimation is performed in the second time window. For example, the base station performs joint channel estimation in each second time window.
[0082] Figure 2 A flow chart showing some embodiments of the communication method on the terminal side of the present disclosure.
[0083] like Figure 2 As shown, in step 210, the maximum time length for the terminal to maintain power consistency and phase continuity is determined based on relevant information of at least one of phase pre-compensation or TA pre-compensation.
[0084] In some embodiments, the maximum duration is determined according to the type of the NTN platform, and different types of NTN platforms correspond to different maximum durations.
[0085] In step 220, the maximum duration is reported to the base station so that the base station configures the first time window according to the maximum duration. For example, the length of the first time window is less than or equal to the maximum duration.
[0086] In some embodiments, when the first time window is configured according to the relevant information of the first precompensation, the timing of performing the second precompensation is determined according to the signaling sent by the base station. The first precompensation is phase precompensation or TA precompensation, and the second precompensation is phase precompensation or TA precompensation, and the first precompensation is different from the second precompensation.
[0087] In some embodiments, the second pre-compensation is performed when the signaling is received and the current second time window ends.
[0088] In step 230, a second time window for transmitting data is determined based on the relevant information of the first time window sent by the base station. The terminal maintains power consistency and phase continuity in the second time window. For example, the base station performs joint channel estimation in the second time window.
[0089] In some embodiments, the second time window is determined based on the relevant information of the first time window and whether an event occurs. For example, if no event occurs, the first time window includes one second time window; if an event occurs, the first time window includes multiple second time windows.
[0090] In the above embodiment, a coverage enhancement method for NTN communication is proposed. When the terminal reports the maximum duration for maintaining power consistency and phase continuity, phase pre-compensation and TA pre-compensation are considered; or, when the terminal reports the maximum duration for maintaining power consistency and phase continuity, phase pre-compensation is considered, but TA pre-compensation is not considered; or, when the terminal reports the maximum duration for maintaining power consistency and phase continuity, TA pre-compensation is considered, but phase pre-compensation is not considered; or, the terminal reports the maximum duration for maintaining power consistency and phase continuity after considering TA pre-compensation and / or phase pre-compensation for different NTN platforms (such as LEO, MEO, GEO, etc.).
[0091] In this way, the terminal considers the pre-compensation information when reporting the maximum duration that can maintain power consistency and phase continuity, which solves the problem of using DMRS bundling technology in NTN scenarios and enables DMRS bundling technology to be applied to NTN scenarios, thereby improving communication performance through joint channel estimation.

[0094] In some embodiments, the communication device 3a further comprises an estimation unit 33a, configured to perform joint channel estimation within the second time window.
[0095] In some embodiments, the sending unit 32a sends signaling to the terminal while configuring the first time window according to relevant information of the first pre-compensation, so that the terminal performs second pre-compensation according to the signaling, the first pre-compensation includes phase pre-compensation or TA pre-compensation, the second pre-compensation includes phase pre-compensation or TA pre-compensation, and the first pre-compensation is different from the second pre-compensation.

[0099] In some embodiments, when no event occurs, the first time window includes one second time window; when an event occurs, the first time window includes multiple second time windows.
