[0090] In some embodiments, a VSAT antenna is generally used in an NTN, and in future designs, it can be considered that the antenna assumption is changed from VSAT to a phase array antenna, so that data transmission of the NTN network can be performed using beam forming / beam forming.
[0091] In some embodiments, using beams can bring the following benefits:
[0092] 1. Providing more flexible beam scheduling based on different service requirements;
[0093] 2. Enhancing coverage, obtaining beamforming gain, wide beam -> narrow beam;
[0094] 3. Reducing interference and improving spectrum efficiency.
[0095] In some embodiments, referring to the beam hopping diagram shown in FIG. IB, using beam hopping technology to solve the imbalance between supply and demand of satellite coverage area can be a research direction in NTN evolution. During the satellite scanning of a group of predefined beam hopping patterns, the activity time of the beam in different areas can be different, thereby meeting the service request.
[0096] In some embodiments, the beam hopping technology can use all available satellite resources to provide services for specific locations or specific users. By adjusting the on time and period of the beam, different capacity values are provided to balance the requirements of different beam coverage areas.
[0097] In some embodiments, referring to the beam dwell time diagram shown in FIG. 1C, for NTN systems that use beam hopping technology, the terminal needs to complete the access process within the current beam's dwell time, otherwise it will cause the problem of increased latency and wasted resources, therefore, how to flexibly configure the dwell time of different beams to meet the different service time requirements of different beams without changing the existing ground network protocol is a problem to be solved.
[0098] In some embodiments, when the beam is not in the current UE's wave position, the UE's behavior can refer to the cell discontinuous transmission / discontinuous reception (Cell DTX / DRX) mechanism in R18 NES (Network Energy Saving).
[0099] In some embodiments, referring to FIG. ID, during Cell DTX, the UE does not expect to receive the following downlink channels / signals: dynamic scheduling new transmission of downlink control information (DCI) or DCI of a specific format, semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), periodic or semi-persistent CSI-RS.
[0100] In some embodiments, referring to FIG. 1D, during the Cell DRX, the UE does not expect to transmit the following uplink channels / signals: uplink transmission corresponding to the cell group CG, periodic / half-persistent CSI reporting, or SRS.
[0101] In some embodiments, the Cell DTX / DRX mechanism configured / activated / deactivated by RRC and dynamically activated / deactivated by DCI format 2-9 is introduced in the NES.
[0102] In some embodiments, the periodic and semi-persistent CSI-RSs associated with the ReportConfig containing the "Rank Indication (RI)" in the report quantity (reportQuantity) can be limited. How to limit the CSI-RSs used for beam management (BM) or radio resource management (RRM) measurement is a problem to be solved.
[0103] In some embodiments, if the terminal only performs CSI-RS measurement within the residence time of the current satellite beam, the CSI-RSs used for RRM measurement, or the CSI-RSs associated with the ReportConfig configured with "Layer 1-Reference Signal Received Power (L1-RSRP) / Layer 1-Signal to Interference plus Noise Ratio (L1-SINR)" are not measured, and the corresponding beam management (handover) or mobility function cannot be implemented.
[0104] Therefore, the present disclosure provides a receiver mechanism of a terminal in a cell / beam non-active state, which can minimize the power consumption caused by the terminal detection and reception while ensuring the reception of the CSI-RSs used for mobility measurement or beam management.
[0105] FIG. 2 is an interaction diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the present disclosure relates to a communication method, which is performed by the communication system 100, and the above method comprises:
[0106] Step S201, the network device 102 sends the first configuration to the terminal 101.
[0107] In some embodiments, the network device is an NTN network device. For example, the network device 102 is a satellite base station, which can be referred to as a satellite for short.
[0108] It should be explained that any satellite beam transmitted by the satellite can illuminate different wave positions at different time periods, that is, it can be understood that the satellite beam scans each wave position in turn. Since the number of satellite beams transmitted by the satellite at the same time is much smaller than the number of wave positions in the satellite coverage area, full coverage of the satellite coverage area by the satellite beam at the same time cannot be achieved. In this case, time division multiplexing satellite beams can be used to provide services to terminals located in different wave positions, which is called beam hopping (BH). It can be understood that the wave position is obtained by dividing the satellite coverage area into single-beam coverage areas, and the coverage area of one satellite beam is a wave position. For example, referring to the wave position represented by the dashed circle in FIG. 1B, all wave positions form a satellite coverage area.
[0109] It should be pointed out that the application scenario of the embodiments of the present disclosure is an NTN scenario using beam hopping technology. In this scenario, the first CSI-RS is received to achieve the purpose of mobility management or beam management.
[0110] In some embodiments, the terminal receives the first configuration. For example, the terminal 101 receives the first configuration sent by the network device 102.
[0111] In some embodiments, the first configuration includes association information between the resource or resource set of one or more CSI-RSs and the satellite beam.
[0112] For example, the first configuration includes configuration content in the following configuration form of one or more CSI-RSs: CSI-RS resource or CSI-RS resource set#index::Duration#index.
[0113] wherein the duration index indicates an index of a specific on-duration of the satellite beam within an association period of the satellite beam corresponding to the CSI-RS. The association period can be the SSB Periodicity indicated in SIB1 (i.e. NCD-SSB period), or can be configured by SIB19 or RRC. For example, assuming the period is M (ms), the granularity of the corresponding satellite beam (i.e. the dwell time of a single satellite beam) is M / N (bitmap length is explicitly configured), then the index indicates the index of the specific on-duration of the satellite beam within the period of M (ms). Alternatively, if a satellite beam corresponds to multiple on-durations within an association period, the index can be configured by bitmap.
[0114] In some embodiments, the name of the first configuration is not limited, for example, it is a satellite beam on-duration configuration, a time domain configuration of a reference signal, etc.
[0115] In some embodiments, step S201 can be omitted, and the terminal can obtain the first configuration from other entities, or the first configuration is default or default.
[0116] In step S202, the terminal 101 determines one or more first wave positions.
[0117] In some embodiments, the terminal determines the current position of the terminal, and determines one or more first wave positions according to the current position of the terminal.
[0118] In some embodiments, the implementation of the terminal determining the current position of the terminal can be that the terminal calculates the current position by itself through at least one of its own Global Navigation Satellite System (GNSS) module, cellular-based Time Difference of Arrival (TDOA), Angle of Arrival (AOA), Round-Trip Time (RTT) positioning method. Alternatively, the position information of the terminal is calculated by a positioning server (LMF), and the position information of the terminal sent by the LMF is received. The present disclosure is not limited in this regard.
[0119] Optionally, the terminal determines the second beam position corresponding to the location of the terminal and / or the adjacent beam position of the second beam position as the first beam position. For example, referring to FIG. 5D, assuming that the terminal is located in the circle area in FIG. 5D, the beam positions corresponding to the beams #1, #2, and #3 can be determined as the first beam position.
[0120] In some embodiments, the first beam position can be associated with a first CSI-RS. One first beam position can be associated with one or more first CSI-RSs, which are not limited in the present disclosure.
[0121] In some embodiments, the first CSI-RS is used for mobility management (MM) and / or beam management (BM). The name of the first CSI-RS is not limited, which is, for example, a target CSI-RS, a conditional CSI-RS, etc.
[0122] In some embodiments, the first CSI-RS includes at least one of the following:
[0123] a channel state information reference signal configured in CSI-RS-Resource-Mobility;
[0124] a channel state information reference signal associated with a first reporting configuration.
[0125] In the first reporting configuration (ReportConfig), the quantity (reportQuantity) reported includes L1-RSRP and / or L1-SINR. The name of the first reporting configuration is not limited, which is, for example, a reporting configuration, a reporting parameter configuration, etc.
[0126] It should be explained that the channel state information reference signal configured in CSI-RS-Resource-Mobility and the channel state information reference signal associated with the first reporting configuration are used for mobility management or beam management, depending on the relationship between the two kinds of cells and satellite beams as follows: the first kind, each cell corresponds to only one satellite beam, which means that the terminal corresponds to the function of performing mobility management. The second kind, each cell corresponds to multiple satellite beams, which means that the terminal corresponds to the function of performing beam management within the cell.
[0127] It should be explained that the channel state information reference signal configured in CSI-RS-Resource-Mobility can be used for mobility management. In the communication system, the mobility management related measurements of the terminal are completed by tracking the CSI-RS signals of the current cell and the neighboring cells, which include radio resource management (RRM) measurements.
[0128] Step S203, the terminal 101 determines a first time period for receiving the first CSI-RS.
[0129] In some embodiments, the first time period is used to represent a specific on duration of the satellite beam in an associated period of the satellite beam corresponding to the first CSI-RS. The first time period is a continuous time period, or the first time period includes multiple non-continuous time periods, which are not limited by the present disclosure.
[0130] The terminal 101 determines the first time period for receiving the first CSI-RS according to the first configuration. For example, if the first configuration includes the association information of the resource or resource set of the first CSI-RS and the satellite beam, the first time period associated with the resource or resource set of the first CSI-RS can be determined according to the first configuration.
[0131] In some embodiments, one first CSI-RS corresponds to one first time period. The present disclosure does not limit the specific number of first CSI-RSs.
[0132] In some embodiments, step S201 can be omitted, and the implementation of step S203 can be that the terminal determines the first time period associated with the resource or resource set of the first CSI-RS. The implementation of the terminal determining the first time period associated with the resource or resource set of the first CSI-RS can be that the first time period associated with the resource or resource set of the first CSI-RS is determined according to a protocol specification, an indication of a network device, default information, or the like.
[0133] Step S204, the terminal 101 determines a non-activation period of a cell / beam of the terminal 101.
[0134] In some embodiments, the cell / beam of the terminal refers to a cell / beam currently serving the terminal, wherein the beam is a satellite beam.
[0135] In some embodiments, the non-activation period of the cell / beam of the terminal 101 refers to a non-satellite beam camping period.
[0136] Step S205, the terminal 101 receives the first CSI-RS in the first time period corresponding to the first CSI-RS.
[0137] In some embodiments, the first CSI-RS is transmitted by a network device, and the terminal receives the first CSI-RS transmitted by the network device in the non-activation period of the current cell / beam and in the first time period corresponding to the first CSI-RS associated with the first beam.
[0138] In some embodiments, step S202 can be omitted, and the terminal 101 receives the corresponding first CSI-RS instead of only the first CSI-RS associated with the first beam position during the non-activation period of the current cell / beam and in the first time period corresponding to the first CSI-RS receivable by each terminal.
[0139] In some embodiments, step S203 can be omitted, and step S205 can be replaced by the terminal receiving the first CSI-RS associated with the first beam position during the non-activation period of the current cell / beam, or the terminal receiving all the first CSI-RSs receivable by each terminal during the non-activation period of the current cell / beam.

For example, step S401 can be implemented as an independent embodiment, and step S402 can be implemented as an independent embodiment, but is not limited to this.

[0190] In some embodiments, step S402 is optional, and one or more of these steps can be omitted or replaced in different embodiments.
[0191] In some embodiments, the present disclosure proposes embodiment 1: an implementation of receiving and measuring CSI-RS by a terminal during the non-activation period of the cell / beam serving the current terminal. Wherein, during the non-activation period of the cell / beam serving the current terminal, the CSI-RS configured in the Channel State Information-Reference Signal-Resource-Mobility (CSI-RS-Resource-Mobility) or the CSI-RS with the report quantity (reportQuantity) in the ReportConfig indicating "L1-RSRP / SINR" (i.e. the first CSI-RS in the foregoing embodiment) needs to be received.
[0192] It should be explained that the above CSI-RS is for RRM (mobility management) or BM (beam management), depending on the relationship between the following two cells (cells) and beams (beams): the first, see Figure 5A, each cell (Cell) corresponds to only one satellite beam (Satellite beam), which means that the UE corresponds to the function of performing mobility management (RRM). The second, see Figure 5B, each cell (Cell) corresponds to multiple satellite beams (Satellite beam), which means that the UE corresponds to the function of performing beam management (BM) within the cell.
[0193] In some embodiments, by configuring, the CSI-RS resource (CSI-RS Resource) or resource set (Resource set) is associated with the satellite beam, specifically, there can be the following configuration form: CSI-RS resource or CSI-RS resource set #index::Duration #index.
[0194] It should be explained that the duration index indicates the index of the specific corresponding on-duration of the current satellite beam in the corresponding association period. The association period can be the SSB Periodicity indicated in SIB1, or configured by SIB19 or RRC, assuming that the period is M (ms), and the granularity of the corresponding satellite beam, i.e., the dwell time of a single beam, is M / N (the bitmap length is explicitly configured); that is, the index at this time indicates the index of the specific corresponding on-duration of the current satellite beam in the M ms period; or if one beam corresponds to multiple Durations in an association period, the bitmap can be used for the configuration. The beam on-duration time diagram corresponding to the CSI-RS can be seen in FIG. 5C.
[0195] In some embodiments, the terminal only expects to receive the CSI-RS during the on-duration of the beam corresponding to the CSI-RS resource or resource set. That is, the CSI-RS is received during the non-active period of the cell / beam serving the current terminal and during the on-duration of the beam corresponding to the CSI-RS resource or resource set.
[0196] In some embodiments, the present disclosure proposes embodiment 2: an implementation of the UE determining the reception of the CSI-RS based on its own geographical position.
[0197] In some embodiments, the UE obtains its own position according to its own position, and at the same time, obtains which beam position or corresponding beam position index (the beam position radius or diameter can be configured by the network side or pre-configured by the protocol, and the center point coordinates of each beam position) it is in, so that the terminal can determine whether to receive the CSI-RS corresponding to the adjacent beam position.
[0198] In some embodiments, referring to FIG. 5D, the UE in the circular area in FIG. 5D only needs to receive the CSI-RS #0, #1, #2 in the dwell time of the beam #0, #1, #2, and does not need to receive other CSI-RS.
[0199] In some embodiments, the UE calculates its position information by itself through its own Global Navigation Satellite System (GNSS) module or a cellular-based Time Difference of Arrival (TDOA) and / or Angle Of Arrival (AOA) and / or Round-Trip Time (RTT) positioning method, or the position information is calculated by a positioning server (LMF) and notified to the terminal.
[0200] In some embodiments, the present disclosure proposes Embodiment 3: in combination with Embodiment 1 and Embodiment 2 described above, that is, for the CSI-RS corresponding to the CSI-RS Resource or Resource set configured with the corresponding lighting Duration, the terminal judges it as a neighboring area, and only expects to receive and detect the corresponding CSI-RS within the corresponding Duration.
[0201] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or can be combined with optional implementation manners of other embodiments.
[0202] The embodiments of the present disclosure also propose a device for implementing any of the above methods, for example, a device including units or modules for implementing each step performed by the terminal in any of the above methods. For another example, another device is also proposed, including units or modules for implementing each step performed by a network device (such as an access network device, a core network function node, a core network device, etc.) in any of the above methods.
[0203] It should be understood that the division of each unit or module in the above apparatus is only a logical function division, and all or part of them can be integrated into a physical entity or physically separated in actual implementation. In addition, the units or modules in the apparatus can be implemented in the form of processor calling software: for example, the apparatus includes a processor, the processor is connected with a memory, the memory stores instructions, and the processor calls the instructions stored in the memory to realize the functions of any of the above methods or the units or modules of the above apparatus, wherein the processor is a general processor such as a central processing unit (CPU) or a microprocessor, and the memory is a memory in the apparatus or a memory outside the apparatus. Alternatively, the units or modules in the apparatus can be implemented in the form of hardware circuit, and the functions of part or all of the units or modules can be realized by the design of the hardware circuit.

In the reconfigurable hardware circuit, the processor loads a configuration document to implement the configuration of the hardware circuit. It can be understood that the processor loads instructions to implement the functions of the above part or all units or modules. In addition, the hardware circuit can also be designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), or the like.
