[0115] In some embodiments, the access network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be referred to as a control unit (control unit). The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0118] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100, or a portion thereof, is shown but is not limited thereto.

[0120] In the relevant protocols, it is proposed to maximize the number of beams that can be activated simultaneously through non-terrestrial networks (NTN) downlink (DL) coverage enhancement to improve the quality and range of downlink signal coverage of the NTN network to the ground or specific areas.

[0121] Optionally, different beam footprints under one satellite in the NTN network belong to different communication cells, that is, each beam covers a specific area; or, different beam footprints under one satellite belong to the same cell. In other words, the beam footprints under one satellite can be one-to-one or many-to-one with the cells.

[0122] Optionally, the 3rd Generation Partnership Project (3GPP) has supported discontinuous transmission (DTX) and / or discontinuous reception (DRX) management mechanisms for cells. For Cell DTX, the cell does not perform downlink transmission during DTX activation. For Cell DRX, the cell does not perform uplink reception during DRX activation.

[0123] Optionally, 3GPP also agrees to extend the period of the synchronization signal block (SSB) to 160 milliseconds (ms) or 320ms. However, during the initial access phase of the terminal (UE), the legacy UE usually assumes that the SSB period is 20ms. Then, for a cell that adopts a 160ms SSB period, the legacy UE may not be able to access the cell.

[0124] Optionally, the cells supporting DL CE that the Legacy UE cannot access can be put into the excluded cell list in the neighboring cells broadcasted by the system message. However, if all neighboring cells on a frequency point are DL coverage enhancement cells that the Legacy UE cannot access, even if the above method is followed, the Legacy UE may still perform measurements on the frequency point and try to detect new cells, which brings unnecessary measurement overhead.

[0125] In some embodiments, it is also proposed to improve the reliability of communication through a store and forward mode.

[0126] Optionally, when the terminal sends uplink data, the terminal can first send the data to the satellite. At this time, if the satellite is not connected to the ground node (such as a gateway), for example, there is no feedback link (feeder link), the satellite can first store the data; afterwards, when the satellite and the ground node are connected, for example, after there is a feeder link, the satellite forwards the data to the ground node (such as a gateway); the ground node can successfully receive the data sent by the UE.

[0127] Optionally, when the terminal sends downlink data, the ground node (gateway or data network) prepares to send data to the terminal. If the ground node is not connected to the satellite at this time (for example, there is no feeder link), the ground node can cache the data first, for example, the serving gateway (Serving Gateway, S-GW) or the mobility management entity (Mobility Management Entity, MME) caches the data first; when the ground node establishes a connection (feeder link) with the satellite, the ground node sends the data to the satellite; if the satellite can establish a connection with the UE, the satellite sends the data to the UE; if the satellite cannot establish a connection with the UE, the satellite saves the data and waits until the satellite establishes a connection with the UE before sending the data to the UE; thereby, the UE completes the downlink data reception.

[0128] For cells that support the store and forward function, legacy terminals may not be able to access such cells normally, so it is also necessary to prevent legacy terminals from accessing such cells. Currently, the solution under discussion is mainly how to prohibit the barring of legacy UEs through the cell barring mechanism. However, the legacy UE will still measure the cell that supports the store and forward function first, then reselect to the cell and read the system message to obtain the barring bit configuration before knowing whether it is barred. The measurement and reselection operations here waste the terminal power consumption.

[0129] The disclosed embodiments propose that, by separately indicating the first information used for measurement for terminals that support downlink coverage enhancement and / or store first and send later, terminals that do not support downlink coverage enhancement and / or store first and send later can accurately determine which frequency points do not need to be measured, thereby avoiding unnecessary measurement overhead.

[0130] The measurement method, communication device, communication system and storage medium provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0131] Figure 2A FIG. 1 is an interactive schematic diagram of a measurement method according to an embodiment of the present disclosure. Figure 2AAs shown, the embodiment of the present disclosure relates to a measurement method performed by a communication system, the communication system includes a terminal and a network device, and the method includes:

[0132] Step S2101, sending configuration information.

[0133] In some embodiments, the configuration information includes first information configured for a terminal supporting one or more of the following: downlink coverage enhancement, and store before send.

[0134] In some embodiments, "the configuration information includes first information configured for a terminal supporting downlink coverage enhancement and / or store first and send later", "the first information in the configuration information is configured for a terminal supporting downlink coverage enhancement and / or store first and send later", "the first information in the configuration information corresponds to the downlink coverage enhancement and / or store first and send later function", and "the first information in the configuration information is associated with the downlink coverage enhancement and / or store first and send later function" can all be used to indicate that a terminal supporting downlink coverage enhancement and / or store first and send later can perform neighboring cell measurements based on the first information. In some scenarios, the above-mentioned various description methods can be interchangeable.

[0135] In some embodiments, the configuration information may be "neighboring cell measurement configuration information".

[0136] In some embodiments, the downlink coverage enhancement may be NTN downlink coverage enhancement.

[0137] In some embodiments, the downlink coverage enhancement function, for example: the SSB period assumed during the initial search of the extended cell is greater than 20ms, or the SSB period is greater than 160ms; or, the downlink coverage enhancement function can be an idle cell and / or inactive cell DTX and / or DRX function for NTN, or, it can also be a connected cell DTX / DRX function for NTN; or, it can also be a coverage enhancement function for any one or more of Message (Msg) 2, Msg4, Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Physical Downlink Shared Channel (PDSCH), and Physical Downlink Control Channel (PDCCH).

[0138] In some embodiments, terms such as "store before sending", "store before sending", "store and send", and "store and forward" can be used to indicate that a communication device can first store data when there is no available communication link, and then forward the data when there is an available communication link. In some scenarios, the above terms can be interchangeable.

[0139] In some embodiments, the network device may send configuration information to the terminal.

[0140] In some embodiments, the terminal may be a New Radio Non-Terrestrial Network User Equipment (NR NTN UE).

[0141] In some embodiments, for the NR NTN network, the configuration information may be provided via one or more of the system information blocks (SIB) 3, SIB4 and SIB5.

[0142] In some embodiments, SIB3 may be used to provide information related to intra-frequency (intra-freq) cell reselection. SIB4 may be used to provide information related to inter-frequency (inter-frequency, inter-freq) cell reselection. SIB5 may be used to provide information related to switching between different radio access technologies (Radio Access Technology, RAT).

[0143] In some embodiments, the terminal may also be Internet of Things Non-Terrestrial Network User Equipment (IOT NTN UE).

[0144] In some embodiments, for IOT NTN using the LTE protocol, the configuration information is provided through one or more of SIB4 (intra-freq), SIB5 (inter-freq), and inter-RAT cell reselection information block for NR (inter-RAT cell reselection for NR) SIB24.

[0145] In some embodiments, the terminal may also be a sixth generation mobile communication user equipment (6th Generation User Equipment, 6GUE).

[0146] In some embodiments, for 6G NTN networks, the configuration information may also be provided by one or more of a SIB providing intra-freq cell reselection configuration, a SIB providing inter-freq cell reselection configuration, and a SIB providing intra-RAT cell reselection configuration.

[0147] In some embodiments, downlink coverage enhancement and store before send are two independent functions, and the network device can provide first information for each function separately. That is, the first information associated with downlink coverage enhancement is different from the first information associated with store before send.

[0148] In some embodiments, the first information associated with downlink coverage enhancement is information configured by the network device for a terminal supporting the downlink coverage enhancement function. The terminal supporting the downlink coverage enhancement function can measure neighboring cells based on the first information.

[0149] In some embodiments, the first information associated with the store-before-send function is information configured by the network device for a terminal supporting the store-before-send function. The terminal supporting the store-before-send function can measure neighboring cells based on the first information.

[0150] In the disclosed embodiment, by separately configuring the associated first information for downlink coverage enhancement and store-before-send functions, conditions are provided for supporting terminals with different capabilities to accurately determine neighboring cells that need to be measured and reduce measurement power consumption.

[0151] In some embodiments, the downlink coverage enhancement and the first information associated with the first store and then send are different, and may include one or more of the following: the cells in the respectively associated neighboring cell lists are different (completely different or not completely the same), the respectively associated measurement types are different, the respectively associated measurement periods, and the respectively associated other measurement parameters are different.

[0152] In some embodiments, the first information associated with downlink coverage enhancement and first store before send are different, and may be completely different from the above items, or at least partially different.

[0153] In some embodiments, the neighbor cell list (neighbor celllist) in the first information associated with downlink coverage enhancement is neighbor cell list#1, and the measurement type is reference signal received power (Reference Signal Receiving Power, RSRP); and the neighbor cell list in the first information associated with save-before-send is neighbor celllist#2, and the measurement type is reference signal received quality (Reference Signal Received Quality, RSRQ).

[0154] In some embodiments, the neighbor cell list (neighbor celllist) in the first information associated with downlink coverage enhancement is neighbor cell list#1, and the measurement type is reference signal receiving power (Reference Signal Receiving Power, RSRP)#1; and the neighbor cell list in the first information associated with save-before-send is neighbor celllist#2, and the measurement type is RSRP#2.

[0155] It should be noted that the above is only an illustrative description of the difference in first information associated with downlink coverage enhancement and store-before-send, and cannot be used as a restrictive description of the difference in first information associated with downlink coverage enhancement and store-before-send.

[0156] In some embodiments, the first information provided separately by the network device for downlink coverage enhancement and store-before-send may be sent through different messages, or may be sent simultaneously through the same message, and the present disclosure does not limit this.

[0157] In some embodiments, the first information may include one or more of the following: a neighbor cell list, an allowed cell list, and an excluded cell list.

[0158] In some embodiments, "excluded cell list", "blacklist cell list", "prohibited cell list", "blocked cell list", "excluded cell list" and the like can be used to indicate cells that do not need to be measured, and in some scenarios the above terms can be interchangeable.

[0159] In some embodiments, measurement information of cells supporting downlink coverage enhancement and / or store-before-send may be indicated by adding a new cell list in the measurement configuration, such as a new neighbor cell list, a new allowed cell list, and a new excluded cell list.

[0160] In the embodiments of the present disclosure, by providing multiple types of cell lists for terminals supporting downlink coverage enhancement and / or storing before sending, conditions are provided for further improving the accuracy of neighbor cell measurement performed by the terminal and reducing the power consumption of neighbor cell measurement performed by the terminal.

[0161] In some embodiments, the configuration information further includes second information configured for a terminal that does not support one or more of the following: downlink coverage enhancement, and store before send.

[0162] In some embodiments, the second information may include one or more of a neighbor cell list, an allowed cell list, and an excluded cell list.

[0163] In some embodiments, the first information and the second information are configured through one configuration information, and in this case, each list included in the first information may be located after each list included in the second information.

[0164] In some embodiments, the second information may be configured via a cell list in an existing measurement configuration.

[0165] For example, for NR NTN terminals, for Inter frequency measurement configuration, the frequency points included in the second information in SIB4, such as the inter-frequency carrier frequency list (interFreqCarrierFreqList) (including without suffix and with suffixes such as v1610, -v1700, -v1720, -v1730, -v1760, -v1800, etc.), are only those cells under which Legacy UE can access, and there are no cells supporting NTN downlink coverage enhancement in which Legacy UE cannot access and / or reside, or both. At the same time, a new first information is introduced, such as Inter frequencycarrier frequency list, and the frequency points in the list are those cells supporting NTN downlink coverage enhancement in which Legacy UE cannot access and / or reside. The newly introduced Inter frequency carrier frequencylist may include some or all parameters in interFreqCarrierFreqList (including those without suffixes and those with suffixes such as v1610, -v1700, -v1720, -v1730, -v1760, -v1800, etc.). For inter-RAT measurement, an Inter-RAT frequency list specifically for NTN downlink coverage enhancement may also be introduced similarly.

[0166] Alternatively, for IOT NTN terminals, for Inter frequency measurement configuration, a new first information may be introduced in SIB5, such as Inter frequency carrier frequency list, the frequency points in the list are those cells that contain Legacy UEs that cannot access and / or reside, and that support NTN downlink coverage enhancement, or cells that support store and forward functions. The newly introduced Inter frequency carrier frequency list may include some or all parameters in interFreqCarrierFreqList and / or interFreqCarrierFreqListExt. If SIB5 is not specifically for cells that support NTN downlink coverage enhancement and / or cells that support store and forward functions, interFreqCarrierFreqList and / or interFreqCarrierFreqListExt may only carry the frequency points of cells that do not contain cells that support NTN downlink coverage enhancement and / or cells that support store and forward functions. For inter-RAT measurements, an Inter-RAT frequency list specifically for NTN downlink coverage enhancement / store and forward may also be introduced similarly.

[0167] Alternatively, for inter RAT NR neighbor cell measurement, a new first information may be introduced in SIB24, such as the Inter frequency carrier frequency list, where the frequencies in the list are those cells that Legacy UE cannot access and / or reside in and that support NTN downlink coverage enhancement, or cells that support the store and forward function.

[0168] In some embodiments, the first information may further include the period of the SSB of the cell. For example, the first information includes that the SSB period is 160ms, so that a terminal supporting the downlink coverage enhancement function can perform random access based on the SSB period, thereby increasing the probability of successful random access.

[0169] In some embodiments, the first information and the second information also include a measurement type to indicate the type of measurement that the terminal needs to perform, such as one or more of a signal strength measurement, such as a reference signal received power (RSRP), a signal quality measurement, such as a reference signal received quality (RSRQ), a load measurement, etc.

[0170] In some embodiments, the first information associated with the store-before-send function also includes a state transfer time associated with the cell.

[0171] In some embodiments, when the state transfer time associated with any cell is reached and the any cell is in an allowed cell list, it can be determined that the any cell is transferred from the allowed cell list to the excluded cell list.

[0172] For example, the state transition time associated with cell#1 in the allowed cell list included in the first information is t1, then after the duration t1 is reached, cell#1 will become a cell in the excluded cell list.

[0173] Alternatively, if the state transition time t1 associated with cell#1 in the allowed cell list included in the first information is reached, then after time t1 is reached, cell#1 will become a cell in the excluded cell list. After time t1 has passed, cell#1 will become a cell in the allowed cell list again.

[0174] In some embodiments, when the state transfer time associated with any cell is reached and the any cell is in the excluded cell list, it can be determined that the any cell is transferred from the excluded cell list to the allowed cell list.

[0175] For example, the state transition time associated with cell#2 in the excluded cell list included in the first information is t2, then after the duration t2 is reached, cell#2 will become a cell in the allowed cell list.

[0176] Alternatively, if the state transition time associated with cell#2 in the excluded cell list included in the first information is t2, then after t2, cell#2 will become a cell in the allowed cell list. After t2, cell#2 will become a cell in the excluded cell list again.

[0177] In some embodiments, the first information associated with the store-before-send function may include a state transition time associated with each cell in the allowed cell list and / or the excluded cell list.

[0178] In some embodiments, the first information associated with the store-before-send function may include state transition times associated with some cells (such as one or several cells) in the allowed cell list and / or excluded cell list. At this time, only the cells associated with the state transition time need to update the cell list to which they belong as time changes.

[0179] In some embodiments, the state transfer time associated with each cell in the first information associated with the store-before-send function may be the same or different.

[0180] In some embodiments, when the state transition times associated with each cell in the first information associated with the store-before-send function are the same, only one state transition time may be included in the first information, thereby reducing the amount of resources occupied by the transmission of the first information.

[0181] In the disclosed embodiment, by configuring the state transfer time associated with the cell, the frequency of the network device sending configuration information to the terminal can be reduced. The terminal can determine the latest state of the cell based on the state transfer time, thereby reducing the frequency of sending system messages and saving power consumption and communication resources.

[0182] Step S2102: The terminal supports downlink coverage enhancement and / or store-before-send, and performs neighbor cell measurement based on the first information and the second information.

[0183] In some embodiments, since terminals that support downlink coverage enhancement can also access the cells included in the second information, such terminals that support downlink coverage enhancement can perform neighboring cell measurements based on the first information associated with downlink coverage enhancement and the second information associated with terminals that do not support downlink coverage enhancement and / or store-before-send.

[0184] In some embodiments, since the terminal that supports save first and send later can also access the cell included in the second information, the terminal that supports save first and send later can perform neighboring cell measurement based on the first information associated with save first and send later and the second information associated with the terminal that does not support downlink coverage enhancement and / or save first and send later.

[0185] For example, the terminal may measure the neighboring cells in the neighboring cell lists respectively indicated in the first information and the second information, such as measuring RSRP, RSRQ, etc. of the neighboring cells.

[0186] In some embodiments, the measurement type, measurement period, and other measurement parameters respectively included in the first information and the second information may be the same or different. When the terminal measures the neighboring cells respectively indicated in the first information and the second information, the terminal may measure the neighboring cells indicated in the first information based on the measurement type, measurement period, and other measurement parameters respectively included in the first information. The terminal may measure the neighboring cells indicated in the second information based on the measurement type, measurement period, and other measurement parameters respectively included in the second information.

[0187] In the disclosed embodiments, a terminal supporting downlink coverage enhancement and / or store-before-send can perform neighbor cell measurements based on the first information and the second information, thereby providing conditions for improving the success rate of cell reselection or switching for such terminals and improving the reliability of such terminals.

[0188] Step S2103: The terminal does not support downlink coverage enhancement and / or store before send, and performs neighbor cell measurement based on the second information.

[0189] In some embodiments, if the terminal does not support downlink coverage enhancement, then only the cells included in the second information associated with not supporting downlink coverage enhancement may be measured.

[0190] In some embodiments, if the terminal does not support store-before-send, then only the cells included in the second information that does not support store-before-send association may be measured.

[0191] In some embodiments, the terminal may measure the neighboring cell indicated in the second information based on the measurement type, measurement cycle and other measurement parameters included in the second information.

[0192] In the embodiment of the present disclosure, a terminal that does not support downlink coverage enhancement and / or store-before-send can perform neighbor cell measurement based only on its associated second information, thereby reducing power consumption wasted by unnecessary neighbor cell measurement while ensuring the accuracy of neighbor cell measurement for such terminal.

[0193] In some embodiments, for a terminal, it can select one of the above steps S2102 and S2103 to execute according to whether it supports downlink coverage enhancement and / or store before send.

[0194] The communication method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2103. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, step S2101+S2102 may be implemented as an independent embodiment, step S2101+S2103 may be implemented as an independent embodiment, etc., but is not limited thereto.

[0195] In this implementation mode or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementation modes or other examples.

[0196] Figure 2B FIG. 1 is an interactive schematic diagram of a measurement method according to an embodiment of the present disclosure. Figure 2B As shown, the embodiment of the present disclosure relates to a measurement method performed by a communication system, which may include a terminal and a network device, and the method includes:

[0197] Step S2201: The network device sends configuration information.

[0198] The configuration information includes first information configured for a terminal supporting one or more of the following: downlink coverage enhancement and store before send.

[0199] In some embodiments, the configuration information also includes second information configured for a terminal that does not support one or more of the following: downlink coverage enhancement first store and then send.

[0200] In some embodiments, the first information includes one or more of the following: a neighbor cell list, an allowed cell list, and an excluded cell list.

[0201] In some embodiments, the above-mentioned first information also includes the period of the synchronization signal block SSB of the cell.

[0202] In some embodiments, the first information associated with the downlink coverage enhancement is different from the first information associated with the store-before-send.

[0203] In some embodiments, the first information further includes a state transition time of cell association, and the method further includes any one of the following:

[0204] When a state transfer time associated with any cell is reached and any cell is in an allowed cell list, determining that the any cell is transferred from the allowed cell list to the excluded cell list;

[0205] When a state transfer time associated with any cell is reached and any cell is in an excluded cell list, it is determined that any cell is transferred from the excluded cell list to the allowed cell list.

[0206] Step S2201: The terminal performs neighbor cell measurement based on the configuration information.

[0207] In some embodiments, the terminal supports downlink coverage enhancement and / or store-before-send, and performs neighbor cell measurement based on the first information and the second information.

[0208] In some embodiments, the terminal does not support downlink coverage enhancement and / or store before send, and performs neighbor cell measurement based on the second information.

[0209] The measurement method provided by the present disclosure is further described below in conjunction with the following embodiments.

[0210] The terminal (UE) receives the neighboring cell measurement configuration information sent by the network, and performs measurement according to the measurement configuration information.

[0211] In some embodiments, the measurement configuration information for NR NTN is provided through one or more of SIB3 (intra-freq), SIB4 (inter-freq) and SIB5 (inter-RAT). For IOT NTN using LTE protocol, the measurement configuration information is provided through one or more of SIB4 (intra-freq), SIB5 (inter-freq) and SIB24 (inter-RAT cell reselection for NR). For 6G NTN, the measurement configuration information is provided through SIB providing intra-freq cell reselection configuration / SIB providing inter-freq cell reselection configuration / SIB providing intra-RAT cell reselection configuration.

[0212] Optionally, the UE is an NR NTN UE or an IOT NTN UE or a 6G UE.

[0213] In some embodiments, the measurement configuration information includes frequency configuration information specifically provided for UE supporting downlink coverage enhancement and / or store and forward functions.

[0214] Optionally, the downlink coverage enhancement may be NTN downlink coverage enhancement.

[0215] Optionally, the downlink coverage enhancement function may be, for example: an SSB period assumed to be greater than 20 ms during initial search of the extended cell, an SSB period greater than 160 ms, idle and / or inactive cell DTX / DRX functions for NTN, a connected cell DTX / DRX function for NTN, one or more of channel coverage enhancement functions such as msg2 / msg4 / PUCCH / PUSCH / PDSCH / PDCCH, etc.

[0216] It should be noted that row coverage enhancement and store and forward are two independent functions, and the specially provided frequency configuration can be provided separately according to the two functions.

[0217] For example, the frequency points of the cell not involving downlink coverage enhancement can be configured through the existing frequency points; the frequency points of the cell involving downlink coverage enhancement are placed in the frequency point configuration information newly introduced for downlink coverage enhancement.

[0218] In some embodiments, for NR NTN, for Inter frequency measurement configuration, the frequency points included in the interFreqCarrierFreqList in SIB4 (including without suffix, and with suffixes of v1610, -v1700, -v1720, -v1730, -v1760, -v1800) are only those cells under which Legacy UE can access, and there are no cells supporting NTN downlink coverage enhancement that Legacy UE cannot access / reside, or both. At the same time, a new Inter frequency carrier frequency list is introduced, and the frequency points in the list are those cells supporting NTN downlink coverage enhancement that Legacy UE cannot access / reside. The newly introduced Inter frequency carrier frequency list may include some or all parameters in interFreqCarrierFreqList (including those without suffixes and those with suffixes of v1610, -v1700, -v1720, -v1730, -v1760, -v1800). For inter-RAT measurement, an Inter-RAT frequency list specifically for NTN downlink coverage enhancement may also be introduced similarly.

[0219] In some embodiments, for IOT NTN, for Inter frequency measurement configuration, a new Inter frequency carrier frequency list may be introduced in SIB5, the frequencies in the list being those cells that support NTN downlink coverage enhancement or cells that support store and forward functions and that Legacy UE cannot access / reside. The newly introduced Inter frequency carrier frequency list may include some or all parameters in interFreqCarrierFreqList / interFreqCarrierFreqListExt. If the interFreqCarrierFreqList / interFreqCarrierFreqListExt in SIB5 is not specifically for cells that support NTN downlink coverage enhancement / cells that support store and forward functions, it may only carry the frequencies that do not include cells that support NTN downlink coverage enhancement / cells that support store and forward functions. For inter-RAT measurements, an Inter-RAT frequency list specifically for NTN downlink coverage enhancement / store and forward may also be introduced similarly.

[0220] In some embodiments, for inter RAT NR neighbor cell measurement, a new Inter frequency carrier frequency list may be introduced in SIB24, where the frequencies in the list include cells supporting NTN downlink coverage enhancement that Legacy UEs cannot access / reside on, or cells supporting store and forward functions.

[0221] Optionally, for a UE supporting downlink coverage enhancement / store and forward, the neighboring cell frequencies measured include frequencies in the frequency configuration information specifically provided for the UE supporting downlink coverage enhancement / store and forward and frequencies in the frequency configuration information not used for downlink coverage enhancement / store and forward.

[0222] In some embodiments, the frequencies in the frequency configuration information not used for downlink coverage enhancement and / or store and forward are interFreqCarrierFreqLis and / or interFreqCarrierFreqListExt. After receiving the special frequency list configuration, the UE supporting NTN downlink coverage enhancement and / or store and forward merges it with the general frequency configuration list to obtain a complete frequency list, and the special frequency list is placed after the general frequency list.

[0223] Optionally, for a UE that does not support downlink coverage enhancement and / or store and forward, the neighboring cell frequencies measured by it are only frequencies in the frequency configuration information that is not used for downlink coverage enhancement and / or store and forward.

[0224] Optionally, the measurement configuration includes one or more of a neighbor cell list, an allowed cell list and an excluded cell list specifically provided for UE supporting downlink coverage enhancement and / or store and forward.

[0225] It should be noted that downlink coverage enhancement and store and forward are two independent functions, and the specially provided neighboring cell configuration can be provided separately according to the two functions.

[0226] In some embodiments, for intra-freq / inter-freq / inter-RAT neighbor cell measurement, the existing general intra-freq / inter-freq / inter-RAT neighbor cell list (such as intraFreqNeighCellList in NR SIB3 or LTE SIB4) and / or allowed neighbor cell list (such as NR SIB3IntraFreqAllowedCellList-r16) and / or excluded cell list (such as LTESIB4IntraFreqExcludedCellList) only contains the neighbor cell list and / or allowed cell list and / or excluded cell list of Legacy UE. The neighbor cell list and / or allowed cell list and / or excluded cell list specifically provided for UE supporting downlink coverage enhancement / store and forward are introduced. Legacy UE determines the neighbor cell list only based on the general intra-freq neighbor cell list and / or allowed neighbor cell list / or excluded cell list, while UE supporting NTN downlink coverage enhancement determines the neighbor cell list based on the general intra-freq / inter-freq / inter-RAT neighbor cell list / allowed neighbor cell list / excluded cell list and the neighbor cell list / allowed neighbor cell list / excluded cell list specially provided for UE supporting downlink coverage enhancement.

[0227] Optionally, the neighboring cell configuration information further includes the SSB period of the cell.

[0228] Optionally, for the allowed cell list and / or excluded cell list specifically for the store and forward function, for the cells that provide the state transition time, after the transition time is reached, the cell attribute changes from allowed to excluded, or from excluded to allowed.

[0229] The embodiments of the present disclosure also propose a device for implementing any of the above methods, for example, a device is proposed, the above device includes a unit or module for implementing each step performed by the terminal in any of the above methods. For another example, another device is also proposed, including a unit or module 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.

[0230] It should be understood that the division of the units or modules in the above device is only a division of logical functions, and in actual implementation, they can be fully or partially integrated into one physical entity, or they can be physically separated. In addition, the units or modules in the device can be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and instructions are stored in the memory. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory inside the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above hardware circuits can be understood as one or more processors; for example, in one implementation, the above hardware circuit is an application-specific integrated circuit (ASIC), and the functions of some or all of the above units or modules are realized by designing the logical relationship of the components in the circuit; for example, in another implementation, the above hardware circuit can be realized by a programmable logic device (PLD), taking a field programmable gate array (FPGA) as an example, which can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by a configuration file, so as to realize the functions of some or all of the above units or modules.
