[0134] It can be understood that the communication system described in the embodiment of the present disclosure is to more clearly illustrate the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of 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.
[0135] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are examples. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0136] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Evolved Universal Terrestrial Radio Access (E-UTRA), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0137] In some embodiments of the present disclosure, the above-mentioned communication system may support NTN technology (e.g., satellite communication). In satellite communication scenarios, there may be very poor channel conditions. For example, when the terminal device does not have line-of-sight communication, its channel fading is deep fading. Compared with line-of-sight communication, the large-scale fading may differ by 18dB. In this case, the terminal device may not be able to receive the paging message sent by the network device (e.g., base station), resulting in paging failure of the terminal device, affecting the user experience.
[0138] In some embodiments, a signal or channel with a low demodulation threshold requirement, called a robust notification, can be introduced. When the terminal device cannot receive the paging information, that is, when the network device cannot page the terminal device, the network device can find the terminal device through the robust notification, and the terminal device can move to a place with better channel conditions to receive the paging message.
[0139] In some embodiments, the name of the robust notification is not limited, and may be, for example, "second information", "downlink information", "pre-paging", "robust alert", etc.
[0140] In some embodiments, receiving robust notifications is a new channel reception method that not all terminal devices support. However, in related technologies, network devices cannot determine whether a terminal device supports robust notifications. Therefore, how network devices can determine this capability of terminal devices has become an urgent issue.
[0141] FIG2A is an interactive diagram illustrating a method for determining terminal capabilities according to an embodiment of the present disclosure. The method may be performed by the above-mentioned communication system. As shown in FIG2A , the method may include:
[0142] Step S2101: The terminal device sends first information to the network device.
[0143] In some embodiments, the network device may receive the first information. For example, the network device may receive the first information sent by the terminal device.
[0144] In some embodiments, the first information may be used to indicate whether the terminal device has a first capability. The first capability may be the ability of the terminal device to receive second information, where the demodulation threshold of the second information is lower than the demodulation threshold of the paging information. Optionally, the terminal device having the first capability may also be referred to as the terminal device supporting the first capability or possessing the first capability. A detailed description of the first capability and the elements that may be included in the first capability will be described in detail later.
[0145] In some embodiments, the second information can lower the demodulation threshold through special encoding and decoding technology, multiple repeated transmissions, occupying more wireless resources, etc., so that the terminal device can correctly demodulate the second information even when it is in poor coverage conditions (for example, coverage conditions that cannot demodulate paging information).
[0146] In some embodiments, the name of the paging information is not limited, and may be, for example, "paging message", "paging", "paging channel", etc.
[0147] In some embodiments, the name of the second information is not limited, and may be, for example, "robust notification", "downlink information", "pre-paging", "robust alert", etc.
[0148] In some embodiments, the name of the first information is not limited, and may be, for example, "uplink information", "capability reporting information", "high robustness capability reporting information", etc.
[0149] In some embodiments, the first information may be carried in at least one of a radio resource control (RRC) message, a medium access control element (MAC CE), uplink control information (UCI), or other messages sent by the terminal device to the network device. Optionally, the first information may be carried via an RRC message.
[0150] In some embodiments, the first information may be information included in a terminal capability report (UE capability report). For example, the first information may be an information element (IE) in the terminal capability report.
[0151] In some embodiments, the first information is optional information in a terminal capability report.
[0152] For example, if the terminal device supports the first capability, the terminal device may carry the first information in the terminal capability report submitted. Accordingly, if the terminal capability report received by the network device contains the first information, the network device determines that the terminal device has the first capability.
[0153] For another example, if the terminal device supports the above-mentioned first capability, the terminal device may carry the first information in the terminal capability report reported, and the first information indicates that the terminal device supports the first capability (for example, the first information may be a specific value). Correspondingly, if the terminal capability report received by the network device contains the first information and the first information indicates that the terminal device supports the first capability, the network device determines that the terminal device has the first capability.
[0154] For another example, if the terminal device does not support the first capability, the terminal device may not carry the first information in the terminal capability report reported. Accordingly, if the terminal capability report received by the network device does not contain the first information, the network device determines that the terminal device does not have the first capability.
[0155] For another example, if the terminal device does not support the first capability, the terminal device carries the first information in the terminal capability report it submits, but the first information indicates that the terminal device does not support the first capability. Correspondingly, if the network device receives a terminal capability report that includes the first information, the first information indicates that the terminal device does not support the first capability, and thus, the network device determines that the terminal device does not have the first capability.
[0156] Optionally, if the first information does not exist in the terminal capability report received by the network device or the first information indicates that the terminal device does not support the first capability, the network device may determine that the terminal device does not support the first capability and will not send the second information to the first terminal.
[0157] In summary, the terminal device can indicate to the network device whether the terminal supports the first capability by using the presence or absence of the first information and the specific content of the first information through the terminal capability report.
[0158] In this way, terminals with different capabilities can be compatible, improving the compatibility of network devices with terminal devices.
[0159] In some embodiments, the terminal capability report may further include third information, which may be used to indicate whether the terminal device supports non-terrestrial network (NTN) capabilities. For example, the third information may be the nonTerrestrialNetwork-r17 field in the terminal capability report. The third information may be part of the first information, or the first information may be included in the third information.
[0160] Optionally, if the third information indicates that the terminal device supports NTN capabilities, the terminal capability report may include the first information. Specifically, the first information may be reported only if the terminal device reports support for NTN. Conversely, if the terminal device does not support NTN, the terminal device may not report the first information, or the reported first information may be invalid. The terminal device may explicitly indicate its NTN support capabilities to the network device. For example, the third information in the terminal capability report may be used to indicate to the network device whether the terminal device supports NTN capabilities. Of course, the terminal device may implicitly indicate its NTN support capabilities through the first information. For example, if the network device receives the first information sent by the terminal, the network device may determine that the terminal device necessarily supports NTN capabilities.
[0161] Optionally, the terminal device supports the first capability by reporting the first information, which may implicitly indicate that the terminal device supports NTN, that is, a prerequisite for the terminal device to support the first capability is that the terminal device supports NTN.
[0162] In this way, the first capability can be bound to the NTN capability, thereby improving the flexibility and reliability of terminal device capability reporting.
[0163] In some embodiments, the first capability may include at least one of the following:
[0164] a second capability, where the second capability is used to indicate that the terminal device supports receiving a first type of physical downlink control channel (PDCCH) scrambled by a first radio network temporary identifier (RNTI), where the first RNTI is an RNTI used for the second information (e.g., robust notification), for example, the first RNTI may be a robust RNTI or a paging RNTI (P-RNTI), and the first type of PDCCH is a group-common PDCCH;
[0165] A third capability is used to indicate that the terminal device supports receiving a second type of PDCCH scrambled by the first RNTI, where the second type of PDCCH is a UE-specific PDCCH. It should be noted that the first RNTI in this embodiment is the RNTI used for the second information, and will not be described in detail below.
[0166] a fourth capability, the fourth capability being used to indicate that the terminal device supports receiving a repeatedly transmitted PDCCH scrambled by the first RNTI; optionally, the repeatedly transmitted PDCCH may be a repeatedly transmitted group-common PDCCH or a repeatedly transmitted UE-specific PDCCH;
[0167] A fifth capability, the fifth capability being used to indicate that the terminal device supports retrieving downlink control information (DCI) scrambled by the first RNTI in a first search space (search space); optionally, the first search space may be a type 3 search space (Type 3-search space);
[0168] A sixth capability, the sixth capability being used to indicate that the terminal device supports obtaining terminal identification (UE ID) information according to the second information, the terminal identification information being indicated in the DCI or indicated by a physical downlink shared channel (PDSCH) scheduled by the DCI, that is, the terminal identification information can be carried directly by the DCI or by a PDSCH scheduled by the DCI; exemplarily, the sixth capability can be used to indicate that the terminal device supports decoding the terminal identification information indicated in the DCI or indicated in the PDSCH scheduled by the DCI;
[0169] A seventh capability, the seventh capability is used to indicate that the terminal device supports obtaining purpose indication information according to the second information, the purpose indication information is indicated by the DCI or indicated by the PDSCH scheduled by the DCI, and the purpose indication information is used to indicate the role of the second information, that is, the purpose indication information can be carried directly by the DCI or by the PDSCH scheduled by the DCI; for example, the seventh capability can be used to indicate that the terminal device supports decoding the purpose indication information indicated in the DCI or indicated in the PDSCH scheduled by the DCI;
[0170] The eighth capability is used to indicate that the terminal device supports sending first feedback information to the network device, where the first feedback information is feedback on whether the terminal device correctly receives the second information; optionally, the first feedback information can be a hybrid automatic repeat request acknowledgment (Hybrid Automatic Repeat Request Acknowledgement, HARQ-ACK).
[0171] That is to say, the first capability may include one or more of the above-mentioned second capability to eighth capability. Alternatively, if the terminal device has one or more of the above-mentioned second capability to eighth capability, the terminal device is considered to have the first capability. Taking the second capability as an example, if the terminal device supports receiving a first type of physical downlink control channel (PDCCH) scrambled by a first radio network temporary identifier (RNTI), the first RNTI is the RNTI used for the above-mentioned second information (such as robust notification), for example, the first RNTI can be a highly robust RNTI or a paging RNTI (Paging RNTI, P-RNTI), and the first type of PDCCH is a group-common PDCCH, then the terminal device is considered to have the second capability, and accordingly, the terminal device is considered to have the first capability.
[0172] In some embodiments, the way in which the terminal device receives PDCCH based on any of the above capabilities can be blind detection. For example, the second capability can be used to indicate that the terminal device supports blind detection of the group-common PDCCH encrypted by the first RNTI; the third capability can be used to indicate that the terminal device supports blind detection of the UE-specific PDCCH encrypted by the first RNTI.
[0173] In some embodiments, the PDCCH scrambled based on the first RNTI is equivalent to a cyclic redundancy check (CRC) carried by the DCI carried by the PDCCH being scrambled by the first RNTI.
[0174] Optionally, the name of the first RNTI is not limited, for example, it can be "specific RNTI", "robust RNTI", etc.
[0175] In some embodiments, the terminal identification information involved in the sixth capability may be a second RNTI, for example, the second RNTI may be a C-RNTI allocated by the network device to the terminal device. Optionally, the terminal identification information may also be other identifiers used to identify the terminal device, such as a temporary mobile subscriber identity (TMSI).
[0176] In some embodiments, the purpose indication information in the seventh capability may be used to indicate a function of the second information, and the function of the second information may include paging and / or notification.
[0177] For example, if the purpose indication information indicates that the function of the second information includes paging, the second information can be used to paging the terminal device or assist in paging the terminal device.
[0178] For another example, if the purpose indication information indicates that the function of the second information includes notification, the second information can be used to send notification information to the terminal device or assist in sending notification information, and the notification information may include at least one of the following: earthquake warning, tsunami warning, typhoon warning, extreme weather warning, etc.
[0179] It should be noted that the second information can directly send a paging or notification, or it can indicate that a paging or notification is to be sent. The terminal device receives the paging or notification through the paging channel or PDSCH based on the second information. For example, after receiving the second information, the terminal device can move to an area with better signal conditions to receive the paging or notification. For another example, after receiving the second information, the terminal device can enhance the antenna receiving capability of the terminal device through software and hardware technologies (such as multiple antennas, adding external antennas, controlling the antenna to extend from the inside to the outside of the terminal device, etc.) to receive the paging or notification. In this way, since the demodulation threshold of the second information is low, the second information can be received under poor signal conditions, and the coverage capability of the terminal device can be improved according to the instructions of the second information to receive paging or notification or other information.
[0180] In this way, through one or more of the above capabilities, the relevant capabilities of the terminal device can be indicated more specifically, thereby improving the flexibility of terminal capability management and use.
[0181] In some embodiments, the second to eighth capabilities described above may be subsets or the entire first capability. For example, the first capability may be equal to the second capability or the third capability; for another example, the first capability may include the second capability and the third capability; or for another example, the first capability may include the second capability, the third capability, and the fifth capability. Any combination of the second to eighth capabilities may serve as the first capability, and these are not further detailed here.
[0182] In other embodiments, one or more of the second to eighth capabilities described above may also be independent capabilities in addition to the first capability. For example, the eighth capability may be a capability independent of the first capability, i.e., the first capability includes the second to seventh capabilities, and the eighth capability may be a separate capability. Optionally, the eighth capability may be dependent on the first capability, i.e., the terminal device can only support the eighth capability if it supports the first capability.
[0183] In some embodiments, the first information may include a parameter, and the parameter may correspond to the first capability, that is, multiple capabilities included in the first capability are combined into one capability information and reported.
[0184] For example, the first information may include a first parameter (e.g., robust notification), which may be used to indicate whether the terminal device supports receiving the second information (high robustness notification). If the terminal device indicates the first parameter (e.g., the reported value of the first parameter is a specific value), the terminal device has the first capability, that is, the terminal device has one or more (e.g., all) of the above-mentioned second capability, third capability, fourth capability, fifth capability, sixth capability, seventh capability, and eighth capability.
[0185] Optionally, the specific value may be 1. For example, if the value of the first parameter reported by the terminal device is 1, it indicates that the terminal device supports receiving the second information, that is, supports the first capability. Conversely, if the value of the first parameter reported by the terminal device is not 1 (for example, 0), or the first parameter is not reported, it indicates that the terminal device does not support receiving the second information, that is, does not support the first capability.
[0186] In this way, if the terminal device reports support for the first capability through a parameter, it can be represented that the terminal device supports one or more of the above-mentioned second to eighth capabilities.
[0187] In other embodiments, the first information may include at least one parameter, each of which may correspond to at least one capability from the second to eighth capabilities included in the first capability, and different parameters may correspond to different capabilities. For example, a parameter may correspond to at least one capability included in the first capability, i.e., any one or a combination of multiple capabilities from the second to eighth capabilities.
[0188] In one implementation, the first information may include multiple parameters, for example, seven parameters, each parameter corresponding to one of the second to eighth capabilities.
[0189] In another implementation, the second to eighth capabilities described above can be arbitrarily combined, and the combined capabilities can be indicated by a parameter in the first information. For example, the second capability and the third capability can be combined and indicated by a parameter in the first information, and the other capabilities can be indicated by independent parameters. For another example, the second capability, the third capability, and the fourth capability can be combined and indicated by a parameter in the first information, the fifth capability, the sixth capability, and the seventh capability can be combined and indicated by another parameter in the first information, and the eighth capability can be indicated by another parameter in the first information. The above method is only an example, and the embodiments of the present disclosure do not limit the method of combining the above capabilities.
[0190] Optionally, the first information may include a second parameter (eg, robust notification) and a third parameter (eg, harq-FeedbackforNotification).
[0191] The second parameter can be used to indicate whether the terminal device supports receiving the second information (high robustness notification). If the terminal device indicates the second parameter (for example, the reported value of the second parameter is a specific value), the terminal device has one or more (for example, all) of the above-mentioned second capability, third capability, fourth capability, fifth capability, sixth capability and seventh capability.
[0192] The third parameter can be used to indicate whether the terminal device supports feedback of the second information (high robustness notification). If the terminal device indicates the third parameter (for example, the reported value of the third parameter is a specific value), the terminal device supports the second new HARQ feedback (that is, the eighth capability mentioned above).
[0193] Optionally, the above-mentioned specific value may be 1. For example, if the value of the third parameter reported by the terminal device is 1, it indicates that the terminal device supports the eighth capability. Conversely, if the value of the third parameter reported by the terminal device is not 1 (for example, 0), or the third parameter is not reported, it indicates that the terminal device does not support the eighth capability.
[0194] Optionally, the third parameter may be dependent on the second parameter. For example, the third parameter may be valid only when the value of the second parameter is a specific value.
[0195] Optionally, there may be dependencies between multiple capabilities of the terminal device.
[0196] For example, the fourth capability may depend on the second capability and / or the third capability, that is, the terminal device can support the fourth capability only when it supports the second capability and / or the third capability.
[0197] For another example, the sixth capability may depend on the fifth capability, that is, the terminal device can support the sixth capability only when it supports the fifth capability.
[0198] For another example, the seventh capability may depend on the fifth capability, that is, the terminal device can support the seventh capability only when it supports the fifth capability.
[0199] For another example, the eighth capability may depend on at least one of the second to seventh capabilities, that is, the terminal device can support the eighth capability only when it supports at least one of the second to seventh capabilities.
[0200] In some embodiments, one terminal device may correspond to one first information, and different terminal devices may report the first information independently. The first information reported by different terminal devices may be the same or different. That is, the first information or first capability is per UE.
[0201] In some embodiments, the first information or first capability may not distinguish between standards and / or frequency bands, that is, the first capability of the same terminal device is the same under all standards and frequency bands it supports, and the same first information is reported.
[0202] In one implementation, the first information of the terminal device does not distinguish between standards, and the standards may include frequency division duplexing (FDD) and time division duplexing (TDD). That is, the terminal device supports the first capability in the same manner under multiple standards (e.g., FDD and TDD), and a single piece of first information may be used to indicate whether the terminal device has the first capability in the multiple standards.
[0203] In one implementation, the first information of the terminal device does not distinguish between frequency ranges, and the frequency ranges may include a first frequency range (FR1, Frequency Range 1) and a second frequency range (FR2). That is, the terminal device supports the first capability in the same manner in multiple frequency ranges (e.g., FR1 and FR2), and a single piece of first information may indicate whether the terminal device has the first capability in the multiple frequency ranges.
[0204] In this way, the content of the first information report can be saved and the occupation of wireless resources can be reduced.
[0205] In some embodiments, the first information or first capability can distinguish different standards, that is, the first capabilities supported by the same terminal device under different standards can be independent (can be different or the same), and the first information corresponding to the standard is reported separately.
[0206] For example, the terminal device may report the first information corresponding to FDD and the first information corresponding to TDD respectively. Optionally, the terminal device may also report the first information corresponding to only one of the modes (eg, FDD or TDD).
[0207] In some embodiments, the first information or first capability can distinguish different frequency ranges or frequency bands (BAND), that is, the first capability supported by the same terminal device in different frequency ranges can be independently configured (can be different), and the terminal device can report the first information corresponding to the frequency range separately.
[0208] For example, the terminal device may report the first information corresponding to FR1 and the first information corresponding to FR2 respectively. Optionally, the terminal device may also report the first information corresponding to only one of the frequency ranges (eg, FR1 or FR2).
[0209] In this way, different first information can be reported according to different standards and / or frequency ranges, thereby improving the flexibility of terminal capability management.
[0210] In some embodiments, step S2101 may be omitted, and the network device may autonomously implement the function indicated by the first information, or the above function may be default or acquiescent.
[0211] In some embodiments, the network device may receive fourth information sent by other network devices, where the fourth information may include the above-mentioned first information. The other network devices may include other core network devices and / or other access network devices.
[0212] For example, the network device is an access network device, and the other network devices may include a core network device and / or other access network devices.
[0213] In some embodiments, the communication system includes multiple network devices. After accessing the network, the terminal device can report the first information to the first network device. The first network device can save the first information (that is, the information on whether the terminal device supports the first capability). If the terminal device moves to the second network device, the second network device can obtain the first information from the first network device to determine whether the terminal device supports the first capability. It should be noted that the network device may include an access network device and / or a core network device. For example, the first information can be reported to the core network device through the access network device and stored on the core network device. For another example, the first information can also be stored on the first access network device and transmitted to the second access network device through the interface between the access network devices.
[0214] Step S2102: The network device sends second information to the terminal device.
[0215] In some embodiments, the terminal device may receive the second information. For example, the terminal device may receive the second information sent by the network device.
[0216] It should be noted that, for the specific implementation of the second information, please refer to the description in step S2101, which will not be repeated here.
[0217] In some embodiments, the second information may be carried in at least one of an RRC message, a MAC CE, downlink control information (DCI), or other messages sent by the network device to the terminal device. Optionally, the second information may be carried in an RRC message. The RRC message may include a system message, such as an SIB message.
[0218] In some embodiments, the network device may determine that the terminal device satisfies the first condition and send the second information. Alternatively, the network device may send the second information to the terminal device if the terminal device satisfies the first condition. Alternatively, the network device may not send the second information to the terminal device if the terminal device does not satisfy the first condition.
[0219] Optionally, the first condition may include at least one of the following:
[0220] The terminal device supports the first capability. For example, whether the terminal device supports the first capability may be determined according to the first information;
[0221] The terminal device is in a first state, which may include an idle state and / or an inactive state;
[0222] The paging of the terminal device fails. For example, after the network device sends a paging message to the terminal device, it does not receive a paging response within a specific time, then it can be determined that the paging of the terminal device has failed. For another example, after the network device sends a paging message to the terminal device N times, it still does not receive a paging response within a specific time after sending the last paging message, then it can be determined that the paging of the terminal device has failed.
[0223] In one implementation, the first condition may include that the terminal device supports the first capability. For example, if the network device determines that the terminal device supports the first capability, it may send the second information to the terminal device. Alternatively, if the network device determines that the terminal device does not support the first capability, it may not send the second information to the terminal device.
[0224] In another implementation, the first condition may include the terminal device being in the first state and the terminal device failing to paging. For example, the network device may send the second information to the terminal device when determining that the terminal device is in the first state and the paging fails.
[0225] In another implementation, the first condition may include that the terminal device supports the first capability, the terminal device is in the first state, and paging of the terminal device fails. For example, the network device may send the second information to the terminal device if it is determined that the terminal device supports the first capability, is in the first state, and paging fails.
[0226] In another implementation, the first condition may include that the terminal device supports the first capability and that the terminal device is in the first state. For example, the network device may send the second information to the terminal device if it is determined that the terminal device supports the first capability and the terminal device is in the first state.
[0227] In another implementation, the first condition may include that the terminal device supports the first capability and that paging of the terminal device fails. For example, the network device may send the second information to the terminal device when it is determined that the terminal device supports the first capability and that paging of the terminal device fails.
[0228] It should be noted that the combination of the first conditions in the above implementation is only an example, and the embodiments of the present disclosure can arbitrarily combine the items in the above first conditions.
[0229] In some embodiments, after the terminal device accesses the network and reports the first information (information supporting the first capability) to the network device through a terminal capability report, the network device can store the capability of the terminal device. When the terminal device is in a first state (for example, an idle or inactive state), the network device can send a second information (robust notification) to the terminal device that supports the first capability.
[0230] In some embodiments, the network device may send the second information and the paging message to the terminal device simultaneously.
[0231] In some embodiments, the network device may send the second information and the paging message to the terminal device when the network device sends the paging message to the terminal device and does not receive a paging response within a specific time, thereby increasing the probability of successful paging.
[0232] In some embodiments, the above steps S2101 and S2102 can be executed in an interchangeable order or simultaneously.
[0233] In some embodiments, the above steps S2101 and S2102 are optional steps.
[0234] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2A .

[0310] FIG5 is a flow chart of a method for determining terminal capabilities according to an embodiment of the present disclosure. As shown in FIG5 , an embodiment of the present disclosure relates to a method for determining terminal capabilities, which can be performed by a communication system and may include:
[0311] Step S5101: The terminal device reports that it has the ability to receive high-robustness notifications.
[0312] In some embodiments, the robust notification can be used to send a downlink channel with stronger coverage than the paging signal to the terminal device when the terminal device cannot receive paging sent by the network, so as to assist the terminal device in receiving paging information.
[0313] In some embodiments, the name of the robust notification is not limited, for example, it can also be called "second information", "pre-paging", "robust alert", etc. The present disclosure does not limit its name.
[0314] In some embodiments, the ability of the terminal device to receive high robustness notifications (or second information) may also be referred to as a first capability.
[0315] In some embodiments, if the terminal device reports the capability or indicates support for the capability in the capability report, the terminal device shall support at least one of the following features:
[0316] Blind detection of the group-common PDCCH scrambled by a specific RNTI, which can be used for robust notification. Optionally, the specific RNTI can be a robust-RNTI or a P-RNTI.
[0317] Blind detection of UE-specific PDCCH scrambled by a specific RNTI, where the specific RNTI can be used for robust notification. Optionally, the specific RNTI can be a robust-RNTI or a P-RNTI.
[0318] receiving a repeatedly transmitted PDCCH scrambled by a specific RNTI, where the specific RNTI may be used for robust notification, and optionally, the specific RNTI may be a robust-RNTI or a P-RNTI;
[0319] Retrieve DCI scrambled by a specific RNTI on a specific search space (search space), where the specific RNTI may be used for robust notification. Optionally, the specific RNTI may be a robust-RNTI or a P-RNTI; optionally, the specific search space may be a Type 3-search space;
[0320] Decoding the terminal identification (UE ID) information indicated in the DCI or indicated in the PDSCH scheduled by the DCI;
[0321] Decoding the purpose indication information indicated in the DCI or the PDSCH scheduled by the DCI;
[0322] Feedback to the base station whether the robust notification information is received correctly, and the feedback information is HARQ-ACK information.
[0323] In some embodiments, the terminal device may report to the network device whether it has the first capability through first information. The first information may be a parameter, for example, the value of the parameter indicates whether the terminal device has the first capability.
[0324] In other embodiments, the terminal device may directly report at least one of the above characteristics to the network device. If the terminal device has a capability corresponding to at least one of the above characteristics, it may be determined that the terminal device has the first capability.
[0325] In some embodiments, the PDCCH is used to carry DCI, and the PDCCH scrambled by a specific RNTI is equivalent to a cyclic redundancy check (CRC) carried by the DCI carried by the PDCCH being scrambled by the specific RNTI;
[0326] In some embodiments, the above features may be combined and reported in one UE capability information. For example, the UE capability information may include a first parameter (robust notification), which may be used to indicate whether the terminal device supports robust notification. If the terminal device indicates this capability, the terminal device supports the following basic features, such as blind decoding of DCI scrambled by a robust RNTI, receiving repeated DCI scrambled by a robust RNTI, and HARQ feedback for robust notification.
[0327] In some embodiments, the above features may be reported through different terminal capability information respectively.
[0328] Optionally, when the above features are reported separately, there may be dependencies.
[0329] For example, the terminal capability information may include a second parameter (robust notification) and a third parameter (harq-FeedbackforNotification), where:
[0330] The second parameter may be used to indicate whether the terminal device supports high robustness notification. If the terminal device indicates the capability corresponding to the second parameter, the terminal device supports the following basic features, such as blind decoding of DCI scrambled by a high robustness RNTI and receiving repeated DCI scrambled by a high robustness RNTI.
[0331] The third parameter may be used to indicate whether the terminal device supports HARQ feedback for high robustness notification. A UE supporting this feature should also indicate support for high robustness notification.
[0332] In some embodiments, the capability of receiving high-robustness notifications may be referred to as a first capability.
[0333] In some embodiments, the first capability may be included in a UE capability report. Optionally, it may be included in a UE-NR-Capability information element.
[0334] In some embodiments, this first capability is optional.
[0335] In some embodiments, the first capability can be reported only when the terminal device reports that it supports NTN.
[0336] For example, the prerequisite capability of the first capability (robustNotification) is the NTN (non-TerrestrialNetwork) capability.
[0337] For another example, a terminal device that supports the first capability (robustNotification) function should also indicate support for the NTN (nonTerrestrialNetwork) capability.
[0338] For another example, the terminal capability information may include a second parameter (robust notification) and a third parameter (harq-FeedbackforNotification), where:
[0339] The second parameter can be used to indicate whether the terminal device supports high robustness notification. If the terminal device indicates the capability corresponding to the second parameter, the terminal device supports the following basic features, such as blind decoding of DCI scrambled by a high robustness RNTI and receiving repeated DCI scrambled by a high robustness RNTI. Terminal devices that support high robustness notification should also indicate support for NTN (nonTerrestrialNetwork) capabilities.
[0340] The third parameter may be used to indicate whether the terminal device supports HARQ feedback for high robustness notification. A UE supporting this feature should also indicate support for high robustness notification.
[0341] In some embodiments, the first capability is per UE, not per band. The same UE may support the same first capability in different bands.
[0342] In some embodiments, the first capability does not distinguish between TDD or FDD.
[0343] In some embodiments, the first capability does not distinguish between FR1 or FR2.
[0344] In some embodiments, after the terminal device reports the first capability information to the network device (e.g., a base station) through the UE capability after accessing the network, the network device may retain the capability. When the terminal device enters an idle state or an inactive state, the network may send a robust notification to the terminal device with the first capability.
[0345] In one embodiment, if the base station to which the terminal device accesses has not changed, for example, it has always been at base station 1, then base station 1 sends a robust notification to the UE.
[0346] In one embodiment, if the base station to which the terminal device accesses has not changed, for example, it has changed from base station 1 to base station 2, base station 2 can obtain the first capability information of the terminal device from the core network device or base station 1 and send a robust notification to the terminal device.
[0347] In this way, the terminal device can report whether it supports the ability to receive high robustness notifications.
[0348] In some embodiments of the present disclosure, a communication system is provided, which may include a terminal device and a network device, wherein the terminal device can execute the method for determining terminal capabilities performed by the terminal device in the aforementioned embodiment of the present disclosure; the network device can execute the method for determining terminal capabilities performed by the network device in the aforementioned embodiment of the present disclosure.
