In some embodiments of the present disclosure, the communication system described above may support NTN technology (e.g., satellite communications). In satellite communications scenarios, there may be situations where the channel conditions are very poor, for example when the terminal device is not in line-of-sight communications, where the channel fading is deep fading, and large scale fading may differ by 18dB from line-of-sight communications. In this case, the terminal device may not receive a paging (paging) message sent by the network device (e.g., a base station), which causes a paging failure problem of the terminal device, and affects user experience.

In some embodiments, a signal or channel with a low demodulation threshold requirement may be introduced, which is called a high robustness notification (robust notification), when the terminal device cannot receive paging information, that is, when the network device cannot page the terminal device, the network device may find the terminal device through the robust notification, and the terminal device may move to a place with better channel conditions to receive the paging message.

In some embodiments, the name of the high robustness notification (robust notification) is not limited, and may be, for example, "second information", "downstream information", "pre-paging", "high robustness alert", or the like.

In some embodiments, reception robust notification is a new channel reception method and not all terminal devices are supported. In the related art, however, the network device cannot acquire whether the terminal device supports the capability of receiving robust notification. Therefore, how to obtain the capability of the terminal device by the network device becomes a problem to be solved.

Fig. 2A is an interactive schematic diagram illustrating a method of determining terminal capabilities according to an embodiment of the present disclosure. The method may be performed by the communication system described above. As shown in fig. 2A, the method may include:

Step S2101, the terminal device transmits first information to the network device.

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.

In some embodiments, the first information may be used to indicate whether the terminal device has a first capability, which may be the capability of the terminal device to receive second information having a demodulation threshold below that of the paging information. Alternatively, the terminal device has a first capability, which may also be referred to as the terminal device supporting or having the first capability. The specific description about the first capability and the elements that the first capability may include will be described in detail later.

In some embodiments, the demodulation threshold may be reduced by a specific codec, repeated transmission for multiple times, occupying more radio resources, etc., so that the second information may be correctly demodulated when the terminal device is in a poor coverage condition (e.g., a coverage condition in which paging information cannot be demodulated).

In some embodiments, the name of the paging information is not limited, and may be, for example, "paging message", "paging channel", etc.

In some embodiments, the name of the second information is not limited, and may be, for example, "high robustness notification (robust notification)", "downlink information", "pre-paging)", "high robustness alert (robust alert)", and the like.

In some embodiments, the name of the first information is not limited, and may be, for example, "uplink information", "capability report information", "high robustness capability report information", and the like.

In some embodiments, the first information may be carried in at least one of a radio resource control RRC (Radio Resource Control) message, a medium access control element MAC CE (Medium Access Control Control Element), uplink control information UCI (Uplink Control Information), or other message sent by the terminal device to the network device. Alternatively, the first information may be carried through an RRC message.

In some embodiments, the first information may be information contained in a terminal capability report (UE capability report). The first information may be, for example, an information element (Information Element, IE) in a terminal capability report.

In some embodiments, the first information is optional information in a terminal capability report.

For example, if the terminal device supports the first capability, the terminal device may carry the first information in the reported terminal capability report. Accordingly, if the first information exists in the terminal capability report received by the network device, the network device determines that the terminal device has the first capability.

For another example, if the terminal device supports the first capability, the terminal device may carry the first information in the reported terminal capability report, and the first information indicates that the terminal device supports the first capability (for example, the first information may be a specific value). Accordingly, if there is first information in the terminal capability report received by the network device 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.

For another example, if the terminal device does not support the first capability, the terminal device may not carry the first information in the reported terminal capability report. Accordingly, if the network device does not have the first information in the terminal capability report received by the network device, the network device determines that the terminal device does not have the first capability.

For another example, if the terminal device does not support the first capability, the terminal device carries the first information in the reported terminal capability report, but the first information indicates that the terminal device does not support the first capability. Accordingly, if the network device receives a terminal capability report, the terminal capability report includes first information indicating that the terminal device does not support the first capability, and thereby the network device determines that the terminal device does not have the first capability.

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 not send the second information to the first terminal.

In summary, the terminal device may indicate to the network device whether the terminal supports the first capability by means of the terminal capability report, using the presence or absence of the first information and the specific content of the first information.

Thus, terminals with different capabilities can be compatible, and the compatibility of the network equipment to the terminal equipment is improved.

In some embodiments, third information may be further included in the terminal capability report, where the third information may be used to indicate whether the terminal device supports capabilities of the non-terrestrial network NTN, and for example, the third information may be a 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.

Optionally, in the case that the third information indicates the capability of the terminal device to support NTN, the terminal capability report may include first information, that is, the first information may be reported when the terminal device reports that NTN is supported, otherwise, if the terminal device does not support NTN, the terminal device may not report the first information, or the reported first information is invalid. The terminal device may explicitly indicate to the network device the support capabilities of the terminal device for NTN. For example, by means of third information in the terminal capability report, indicates to the network device whether the terminal device supports NTN capabilities. Of course, the terminal device may implicitly indicate the capability of the terminal device to support NTN through the first information, e.g., if the network device receives the first information sent by the terminal, the network device may determine that the terminal device must support the capability of NTN.

Optionally, the terminal device may implicitly indicate that the terminal device supports NTN by reporting the first information to support the first capability, that is, the precondition that the terminal device supports the first capability is that the terminal device supports NTN.

Therefore, the first capability and the NTN capability can be bound, and the flexibility and reliability of reporting the capability of the terminal equipment are improved.

In some embodiments, the first capability may include at least one of:

A second capability for indicating that the terminal device supports receiving a first type of physical downlink control channel (Physical Downlink Control Channel, PDCCH) scrambled by a first radio network temporary identity (Radio Network Temporary Identifier, RNTI), the first RNTI being an RNTI for the second information (e.g., robust notification) described above, which may be, for example, a high robustness (robust) RNTI or a paging RNTI (PAGING RNTI, P-RNTI), the first type of PDCCH being a group-common PDCCH;

A third capability, where the third capability is used to instruct the terminal device to support receiving a second type PDCCH scrambled by the first RNTI, where the second type PDCCH is a terminal dedicated PDCCH (UE-SPECIFIC PDCCH), and it should be noted that, in this embodiment, the first RNTI is an RNTI for the second information, which is not described in detail below;

A fourth capability, configured to instruct the terminal device to support receiving a PDCCH scrambled by the first RNTI for repeated transmission; alternatively, the retransmitted PDCCH may be a retransmitted group-common PDCCH or a retransmitted UE-SPECIFIC PDCCH;

A fifth capability for instructing the terminal device to support retrieving downlink control information DCI (Downlink Control Information) scrambled by the first RNTI within a first search space (SEARCH SPACE); optionally, the first search space may be a Type3 search space (Type 3-SEARCH SPACE);

A sixth capability, configured to instruct the terminal device to support acquiring terminal identification (UE ID) information according to the second information, where the terminal identification information is indicated by a physical downlink common channel (Physical Downlink SHARED CHANNEL, PDSCH) indicated in DCI or scheduled by DCI, that is, the terminal identification information may be directly carried by DCI or carried by PDSCH scheduled by DCI; for example, the sixth capability may be used to instruct the terminal device to support decoding terminal identification information indicated in DCI or indicated in PDSCH of DCI schedule;

A seventh capability, configured to instruct the terminal device to support acquiring, according to the second information, destination indication information, where the destination indication information is indicated by DCI or PDSCH scheduled by DCI, and the destination indication information is configured to indicate an effect of the second information, that is, the destination indication information may be directly carried by DCI or may be carried by PDSCH scheduled by DCI; for example, the seventh capability may be used to instruct the terminal device to support decoding the destination indication information indicated in the DCI or indicated in the PDSCH of the DCI schedule;

An eighth capability, configured to instruct the terminal device to support sending first feedback information to the network device, where the first feedback information is feedback that whether the terminal device correctly receives the second information; alternatively, the first feedback information may be a hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat Request Acknowledgement, HARQ-ACK).

That is, the first capability may include one or more of the above-described second to eighth capabilities. Or if the terminal device has one or more of the above-mentioned second to eighth capabilities, 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 (Physical Downlink Control Channel, PDCCH) scrambled by a first radio network temporary identity (Radio Network Temporary Identifier, RNTI), which is an RNTI for the above second information (e.g. robust notification), for example, the first RNTI may be a high robustness RNTI or paging RNTI (PAGING RNTI, P-RNTI), which is a group-common PDCCH, the terminal device is considered to have the second capability, and accordingly the terminal device is considered to have the first capability.

In some embodiments, the manner in which the terminal device receives the PDCCH based on any of the above capabilities may be blind detection, for example, the second capability may be used to instruct the terminal device to support blind detection of the first RNTI scrambled group-common PDCCH; a third capability may be used to instruct the terminal device to support blind detection of the first RNTI scrambled UE-SPECIFIC PDCCH.

In some embodiments, the PDCCH scrambled based on the first RNTI is equivalent to a cyclic redundancy check (Cyclic Redundancy Check, CRC) carried by DCI carried by the PDCCH.

Alternatively, the name of the first RNTI is not limited, and may be, for example, "specific RNTI", "robust RNTI", or the like.

In some embodiments, the terminal identification information related to the sixth capability may be a second RNTI, for example, the second RNTI may be a C-RNTI allocated by the network device for the terminal device. Alternatively, the terminal identification information may be other identifications for determining the terminal device, such as a temporary mobile subscriber identity (Temporary Mobile Subscriber Identity, TMSI) or the like.

In some embodiments, the destination indication information in the seventh capability may be used to indicate an effect of the second information, which may include paging and/or notification.

For example, if the destination indication information indicates that the effect of the second information includes paging, the second information may be used to page the terminal device or to assist in paging the terminal device.

For another example, if the destination indication information indicates that the role of the second information includes notification, the second information may be used to send notification information or auxiliary send notification information to the terminal device, where the notification information may include at least one of: earthquake early warning, tsunami early warning, typhoon early warning, extreme weather early warning and the like.

The second information may directly send the paging or notification, or may indicate that the paging or notification is to be sent, and the terminal device receives the paging or notification through the paging channel or PDSCH based on the second information. For example, the terminal device may move to an area with better signal condition to receive the paging or notification after receiving the second information, and for example, the terminal device may enhance the antenna receiving capability of the terminal device by using a software and hardware technology (such as multiple antennas, adding an external antenna, controlling the antenna to extend from the inside to the outside of the terminal device, etc.) after receiving the second information, so as to receive the paging or notification. Thus, since the demodulation threshold of the second information is low, the second information can be received under the condition of poor signal, and the coverage capability of the terminal equipment is improved according to the indication of the second information so as to receive paging or notification or other information.

In this way, the relevant capabilities of the terminal device may be more specifically indicated by one or more of the above-mentioned capabilities, thereby improving the flexibility of terminal capability management and use.

In some embodiments, the second capability to the eighth capability may be a subset or a full set of the first capability. For example, the first capability may be equal to the second capability or the third capability; as another example, the first capability may include a second capability and a third capability; as another example, the first capability may include a second capability, a third capability, and a fifth capability; any combination of the second capability to the eighth capability may be used as the first capability, and will not be described herein.

In other embodiments, one or more of the second capability to the eighth capability may be a separate capability other than the first capability. For example, the eighth capability may be a capability independent from the first capability, i.e., the first capability includes the second capability through the seventh capability, and the eighth capability may be a separate capability. Alternatively, the eighth capability may depend on the first capability, i.e. the eighth capability can only be supported if the terminal device supports the first capability.

In some embodiments, the first information may include a parameter, where the parameter may correspond to the first capability, that is, a plurality of capabilities included in the first capability are combined and reported in one capability information.

For example, the first information may include a first parameter (e.g., robust notification) that 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 a first capability, i.e. 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, eighth capability.

Alternatively, the specific value may be 1, for example, if the value of the first parameter reported by the terminal device is 1, the terminal device is indicated to support receiving the second information, that is, to support the first capability. Otherwise, if the value of the first parameter reported by the terminal device is not 1 (e.g. 0), or the first parameter is not reported, the terminal device is indicated not to support receiving the second information, that is, not to support the first capability.

In this way, the terminal device supports the first capability through a parameter report, and may characterize that the terminal device supports one or more of the second capability to the eighth capability.

In other embodiments, the first information may include at least one parameter, each of the at least one parameter may correspond to at least one of the second capability to the eighth capability included in the first capability, and different parameters may correspond to different capabilities. For example, one parameter may correspond to at least one of the capabilities included in the first capability, i.e., a combination of any one or more of the second capability through the eighth capability.

In one implementation, the first information may include a plurality of parameters, e.g., seven parameters, each corresponding to one of the second capability through the eighth capability.

In another implementation manner, the second capability to the eighth capability may be arbitrarily combined, and the combined capability is indicated by a parameter in the first information. For example, the second capability and the third capability may be combined and indicated by one parameter in the first information, and the other capability may be indicated by separate parameters, respectively. For another example, the second capability, the third capability, and the fourth capability may be combined and indicated by one parameter in the first information, the fifth capability, the sixth capability, and the seventh capability may be combined and indicated by another parameter in the first information, and the eighth capability may be indicated by another parameter in the first information. The above manner is merely an example, and the embodiments of the present disclosure do not limit the manner in which the above capabilities are combined.

Optionally, the first information may include a second parameter (e.g., robust notification) and a third parameter (e.g., harq-FeedbackforNotification). Wherein:

The second parameter may be used to indicate whether the terminal device supports receiving the second information (high robustness notification). If the terminal device indicates the second parameter (e.g. the reported value of the second parameter is a specific value), the terminal device has one or more (e.g. all) of the above-mentioned second capability, third capability, fourth capability, fifth capability, sixth capability and seventh capability.

The third parameter may 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 (e.g. the reported value of the third parameter is a specific value), the terminal device supports the second new HARQ feedback (i.e. the eighth capability described above).

Alternatively, the specific value may be 1, for example, if the value of the third parameter reported by the terminal device is 1, indicating that the terminal device supports the eighth capability. Otherwise, if the value of the third parameter reported by the terminal device is not 1 (e.g. 0), or the third parameter is not reported, the terminal device is indicated to not support the eighth capability.

Alternatively, the third parameter may have a dependency relationship with the second parameter, for example, the third parameter may be valid if the value of the second parameter is a specific value.

Alternatively, there may be a dependency between the capabilities of the terminal device.

For example, the fourth capability may depend on the second capability and/or the third capability, i.e. the terminal device is able to support the fourth capability only if the second capability and/or the third capability are supported.

As another example, the sixth capability may rely on the fifth capability, i.e. the terminal device is able to support the sixth capability if it is supported.

For another example, the seventh capability described above may rely on the fifth capability, i.e. the terminal device is able to support the seventh capability in case the fifth capability is supported.

For another example, the eighth capability described above may depend on at least one of the second capability to the seventh capability, i.e. the terminal device is able to support the eighth capability only if the at least one of the second capability to the seventh capability is supported.

In some embodiments, one terminal device may correspond to one first information, and different terminal devices may report the first information independently, and the first information reported by different terminal devices may be the same or different. I.e. the first information or the first capability is of the per UE.

In some embodiments, the first information or the first capability may not distinguish between the modes and/or the frequency bands, that is, the same terminal device may report the same first information when the first capability of the same terminal device is the same in all modes and frequency bands supported by the terminal device.

In one implementation, the first information of the terminal device is not differentiated by a system, which may include frequency division duplexing (Frequency Division Duplexing, FDD), time division duplexing (Time Division Duplexing, TDD). That is, the terminal device may have the same support for the first capability in a plurality of systems (e.g., FDD and TDD), and may indicate whether the terminal device has the first capability in the plurality of systems through one piece of first information.

In one implementation, the first information of the terminal device does not distinguish between Frequency ranges, which may include a first Frequency Range (FR 1, frequency Range 1), a second Frequency Range (Frequency Range 2, FR 2). I.e. the support of the first capability by the terminal device in a plurality of frequency ranges, e.g. FR1 and FR2, is the same, it may be indicated by a first information whether the terminal device has the first capability in the plurality of frequency ranges.

Therefore, the content of the first information report can be saved, and the occupation of wireless resources is reduced.

In some embodiments, the first information or the first capability may distinguish different formats, that is, the first capabilities supported by the same terminal device in different formats may be independent (may be different or the same), and the first information corresponding to the formats is reported separately.

For example, the terminal device may report the first information corresponding to FDD and the first information corresponding to TDD respectively. Alternatively, the terminal device may report only the first information corresponding to one of the standards (for example, FDD or TDD).

In some embodiments, the first information or the first capability may distinguish between different frequency ranges or frequency BANDs (BANDs), that is, the first capabilities supported by the same terminal device in different frequency ranges may be configured independently (may be different), and the terminal device may report the first information corresponding to the frequency ranges respectively.

For example, the terminal device may report the first information corresponding to FR1 and the first information corresponding to FR2, respectively. Alternatively, the terminal device may report only the first information corresponding to one of the frequency ranges (for example, FR1 or FR 2).

In this way, different first information can be reported according to different systems and/or frequency ranges, and flexibility of terminal capability management is improved.

In some embodiments, this step S2101 may be omitted, and the network device may autonomously implement the function indicated by the first information, or the above-mentioned function may be a default or default.

In some embodiments, the network device may receive fourth information sent by other network devices, which may include the first information described above, and the other network devices may include other core network devices and/or other access network devices.

For example, the network device is an access network device, and the other network devices may include core network devices and/or other access network devices.

In some embodiments, the communication system includes a plurality of network devices, after the terminal device accesses the network, the terminal device may report the first information to the first network device, the first network device may store the first information (i.e. whether the terminal device supports the first capability), and if the terminal device moves to the second network device, the personal network device may acquire the first information from the first network device, so as 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 may be reported to the core network device by the access network device and stored on the core network device. For another example, the first information may also be stored on the first access network device and transferred to the second access network device via an interface between the access network devices.

Step S2102, the network device sends second information to the terminal device.

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.

It should be noted that, regarding the specific implementation manner of the second information, reference may be made to the description in step S2101, which is not repeated here.

In some embodiments, the second information may be carried in at least one of an RRC message, a MAC CE, downlink control information DCI (Downlink Control Information), or other message sent by the network device to the terminal device. Alternatively, the second information may be carried through an RRC message. The RRC message may include a system message, such as a SIB message.

In some embodiments, the network device may determine that the terminal device satisfies the first condition and transmit the second information. Alternatively, the network device may send the second information to the terminal device in case it is determined that the terminal device satisfies the first condition. Alternatively, the network device may not send the second information to the terminal device in case it is determined that the terminal device does not meet the first condition.

Optionally, the first condition may include at least one of:

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;

The terminal device is in a first state, which may include an idle state and/or an inactive state;

The paging failure of the terminal device, for example, after the network device sends the paging message to the terminal device, the paging failure of the terminal device can be determined if the paging response is not received within a specific time; for another example, after the network device sends N paging messages to the terminal device, the paging failure of the terminal device may be determined if the paging response is not received within a specific time after the last paging message is sent.

In one implementation, the first condition may include the terminal device supporting the first capability. For example, the network device may send the second information to the terminal device in case it is determined that the terminal device supports the first capability. Alternatively, the network device may not send the second information to the terminal device in case it is determined that the terminal device does not support the first capability.

In another implementation, the first condition may include that the terminal device is in the first state, and that the terminal device fails to page. For example, the network device may send the second information to the terminal device in case it is determined that the terminal device is in the first state and the paging fails.

In another implementation, the first condition may include the terminal device supporting the first capability, the terminal device being in the first state, and the terminal device failing to page. 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 fails paging.

In yet another implementation, the first condition may include the terminal device supporting the first capability and the terminal device being 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 that the terminal device is in the first state.

In yet another implementation, the first condition may include the terminal device supporting the first capability and the terminal device failing to page. For example, the network device may send the second information to the terminal device in case it is determined that the terminal device supports the first capability and that the terminal device fails paging.

It should be noted that, the combination of the first conditions in the foregoing implementation manner is merely an example, and any combination of the respective items in the foregoing first conditions may be implemented in the embodiments of the present disclosure.

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 the terminal capability report, the network device may store the capability of the terminal device, and when the terminal device is in the first state (e.g., idle or inactive state), the network device may send the second information to the terminal device supporting the first capability (robust notification).

In some embodiments, the network device may send the second information and the paging message to the terminal device simultaneously.

In some embodiments, the network device may send the second information and the paging message to the terminal device if the paging message is sent to the terminal device and the paging response is not received within a specific time. In this way, the probability of paging success can be increased.

In some embodiments, the above step S2101 and step S2102 may be performed in an exchange order or simultaneously.

In some embodiments, step S2101 and step S2102 are optional steps.

a group-common PDCCH scrambled with a specific RNTI, which may be used for robust notification, alternatively, a robust-RNTI or a P-RNTI, is blind-detected;

A blind-check for a particular RNTI scrambled UE-SPECIFIC PDCCH, which may be used for robust notification, alternatively the particular RNTI may be a robust-RNTI or a P-RNTI;

receiving a retransmission PDCCH scrambled with a specific RNTI, which may be used for robust notification, alternatively, a request-RNTI or a P-RNTI;

Retrieving DCI scrambled by a specific RNTI on a specific search space (SEARCH SPACE), which may be used for robust notification, alternatively, the specific RNTI may be a robust-RNTI or a P-RNTI; alternatively, the particular search space may be Type3-SEARCH SPACE;

decoding terminal identification (UE ID) information indicated in DCI or indicated in PDSCH of DCI schedule;

decoding destination indication information indicated in DCI or indicated in DCI scheduled PDSCH;

and feeding back robust notification information whether the information is received correctly or not to the base station, wherein the feedback information is HARQ-ACK information.

In some embodiments, the terminal device may report to the network device whether the terminal device has the first capability or not through first information, which may be a parameter, for example, indicating whether the terminal device has the first capability or not through a value of the parameter.

In other embodiments, the terminal device may report at least one of the features directly to the network device, and if the terminal device has a capability corresponding to the at least one feature, it may be determined that the terminal device has the first capability.

In some embodiments, the PDCCH is used to carry DCI, and the PDCCH scrambled by the specific RNTI corresponds to a Cyclic Redundancy Check (CRC) carried by the DCI carried by the PDCCH;

In some embodiments, the above features may be combined in one UE capability information, e.g., the UE capability information may include a first parameter (robust notification) that may be used to indicate whether the terminal device supports high-robustness notifications. If the terminal device indicates this capability, the terminal device supports basic features such as blind decoding of DCI scrambled by a high robust RNTI, receiving repeated DCI scrambled by a high robust RNTI, HARQ feedback for high robust notification.

In some embodiments, the above features may be reported through different terminal capability information, respectively.

Alternatively, there may be a dependency relationship when the above features are reported separately.

By way of example, the terminal capability information may include a second parameter (robust notification) and a third parameter (harq-FeedbackforNotification), wherein:

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 basic features such as blind decoding of DCI scrambled by the high robust RNTI, receiving repeated DCI scrambled by the high robust RNTI.

The third parameter may be used to indicate whether the terminal device supports HARQ feedback for the high robustness notification. The UE supporting this feature should also indicate support for high robustness notifications.

In some embodiments, the capability of receiving a high robustness notification may be referred to as a first capability.

In some embodiments, the first capability may be included in a terminal capability report (UE capability report) reporting. Optionally, may be included in the UE-NR-Capability information element.

In some embodiments, this first capability is optional.

In some embodiments, the first capability may be reported only if the terminal device reports support NTN.

For example, the precondition capability (prerequisite capability) of the first capability (robustNotification) described above is a NTN (nonTerrestrialNetwork) capability.

As another example, a terminal device supporting the first capability (robustNotification) function should also indicate support NTN (nonTerrestrialNetwork) capability.

As another example, the terminal capability information may include a second parameter (robust notification) and a third parameter (harq-FeedbackforNotification), wherein:

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 basic features such as blind decoding of DCI scrambled by the high robust RNTI, receiving repeated DCI scrambled by the high robust RNTI. The terminal device supporting the high robustness notification should also indicate support for NTN (nonTerrestrialNetwork) capabilities.

In some embodiments, the first capability is per terminal equipment (per UE), not per band (per band). The first capability supported by the same terminal device in different frequency bands is the same.

In some embodiments, the first capability does not distinguish between TDD or FDD.

In some embodiments, the first capability does not distinguish FR1 or FR2.

In some embodiments, after the access network reports the first capability information to the network device (e.g., the base station) through UE capability, the network device may reserve the capability, and when the terminal device enters an idle state or an active state, the network may send robust notification to the terminal device with the first capability.

In one embodiment, if the base station to which the terminal device accesses is unchanged, for example, is always in base station 1, then base station 1 sends robust notification to the UE.

In one embodiment, if the base station to which the terminal device accesses is unchanged, for example, the base station 1 is changed to the base station 2, the base station 2 may acquire the first capability information of the terminal device from the core network device or the base station 1, and send robust notification to the terminal device.

In this way, the terminal device can report whether the capability of receiving high robustness notifications is supported.
