[0026] This disclosure provides a rescue request method, communication equipment, communication system, and storage medium.

[0027] In a first aspect, embodiments of this disclosure propose a rescue request method, executed by a terminal, the method comprising: determining that a first event has occurred, and sending first information to a network device; wherein the first event indicates that rescue is needed, and the first information is used to request rescue.

[0033] In conjunction with some embodiments of the first aspect, in some embodiments, the first information includes a first sequence corresponding to the rescue-related information, wherein different rescue-related information corresponds to different first sequences.

[0034] In conjunction with some embodiments of the first aspect, in some embodiments, sending the first information to the network device includes at least one of the following: sending the first information via first signaling; sending the first information via the user plane.

[0035] In conjunction with some embodiments of the first aspect, in some embodiments, the first signaling is used to send first information corresponding to a first event, or the first signaling is used to send first information corresponding to multiple first events.

[0036] In conjunction with some embodiments of the first aspect, in some embodiments, the first signaling is different from the second signaling, and the second signaling is used to send information other than the first information.

[0037] In conjunction with some embodiments of the first aspect, in some embodiments, the first signaling is processed by a first layer of the terminal, which is different from a second layer, which is used to process signaling other than the first signaling.

[0038] In conjunction with some embodiments of the first aspect, in some embodiments, the first signaling includes at least one of non-access stratum (NAS) signaling, access stratum (AS) signaling, and media access control unit (MAC CE) signaling.

[0039] In conjunction with some embodiments of the first aspect, in some embodiments, the first information satisfies at least one of the following: the service type corresponding to the first information is a first service type, the first service type is different from a second service type, and the second service type is a service type corresponding to information other than the first information; the first information corresponds to a first quality of service (QoS) requirement, the first QoS requirement is different from a second QoS requirement, and the second QoS requirement is a QoS requirement corresponding to information other than the first information; the first information corresponds to a first transmission reliability requirement, the first transmission reliability requirement is different from a second transmission reliability requirement, and the second transmission reliability requirement is a transmission reliability requirement corresponding to information other than the first information.

[0040] In conjunction with some embodiments of the first aspect, in some embodiments, the first information is repeatedly transmitted K times within a resource block, where K>1 and K is an integer.

[0041] In the above embodiments, the method of sending the first information is described, and the specific transmission methods of the terminal when requesting emergency rescue are clarified, so that the terminal can successfully request emergency rescue from the network device.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes at least one of the following: determining one or more first resource sets based on a protocol agreement; receiving second information sent by the network device, the second information being used to configure one or more first resource sets.

[0043] In conjunction with some embodiments of the first aspect, in some embodiments, sending the first information to the network device includes: there are multiple first resource sets, selecting a second resource set from the multiple first resource sets; and sending the first information based on the second resource set.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, selecting a second resource set from a plurality of first resource sets includes at least one of the following: randomly selecting a second resource set from a plurality of first resource sets; selecting a second resource set from a plurality of first resource sets based on a uniform distribution; selecting the first resource set from a plurality of first resource sets that is most recent in time as the second resource set; selecting the first resource set from a plurality of first resource sets that corresponds to the first event as the second resource set, wherein different first events correspond to different first resource sets.

[0045] The above embodiments illustrate which resources the terminal can use to send the first information, ensuring the successful transmission of the first information.

[0046] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: sending a first request to the network device, the first request being used to request the sending of the first information.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, the first request includes a scheduling request (SR), or the first request includes a second sequence.

[0048] In conjunction with some embodiments of the first aspect, in some embodiments, sending the first request to the network device includes at least one of the following: sending a first request corresponding to a second resource set to the network device, wherein different second resource sets correspond to different first requests; sending a first request corresponding to the first event to the network device, wherein different first events correspond to different first requests.

[0049] In conjunction with some embodiments of the first aspect, in some embodiments, at least one of the sending resources of the first request and the generation method of the second sequence is agreed upon by a protocol and / or pre-configured by a network device.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: after sending the first request, determining whether a feedback message from the network device is received within a first time window; if the feedback message is not received within the first time window, sending the first information.

[0051] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: after sending the first request, determining whether a feedback message from the network device is received within a first time window; if the feedback message is not received within the first time window, then sending the first request again, wherein each time the first request is sent, the terminal determines whether the feedback message is received within the first time window; if the feedback message is received within the first time window, then sending the first request stops, and the first information is sent at least M time units after the time of receiving the feedback message, where M is a positive integer and M is related to the preparation time of the first information; if the feedback message is not received, then sending the first request again, the maximum number of times the first request is sent is N, where N > 0 and N is an integer.

[0053] In the above embodiments, before sending the first information, the terminal can send a first request to the network device to request the sending of the first information. That is, before sending the first information, the terminal sends a first request to inform the network device that it is about to send the first information. Therefore, for the network device, if it does not receive the first request, it means that the terminal will not send the first information at this time. The network device can then allocate the transmission resources for the first information to other transmissions, preventing the transmission resources for the first information from being idle, reducing spectrum resource waste, and improving resource utilization. Furthermore, when the network device receives the first request, it means that the terminal needs to send the first information. The network device will then reserve the transmission resources for the first information and will not use these resources for other scheduling, thereby ensuring the successful transmission of the first information and guaranteeing the timeliness of the rescue request.

[0115] Optionally, due to the wide coverage of NTN, in some embodiments, in uninhabited areas, remote mountainous regions, or areas where terrestrial network (TN) base station coverage is insufficient in other countries, NTN satellite communication can be used for emergency rescue operations. For example, NTN satellite communication can be used for search and rescue operations in natural disasters, medical emergencies, sudden incidents, traffic accidents, and situations where people are trapped in mountainous areas. However, the specific content and transmission methods that a terminal needs to send when requesting emergency rescue are currently not clearly defined.

[0116] Figure 2A is an interactive schematic diagram of a rescue request method according to an embodiment of the present disclosure. As shown in Figure 2A, this embodiment of the disclosure relates to a rescue request method for a communication system 100; the method includes:

[0117] Step 2101: The terminal determines that the first event has occurred.

[0118] Optionally, the first event can be used to indicate the need for rescue. In some embodiments, the first event may be referred to as a rescue event, an emergency rescue event, an urgent event, etc., and this disclosure does not specifically limit it. For example, the first event may include at least one of the following: a natural disaster event, a medical emergency event, an attack event, a sudden event, a traffic accident, being trapped in a mountainous area, etc. Optionally, the aforementioned natural disaster events may include, for example, mudslides, landslides, floods, blizzards, earthquakes, etc. The aforementioned sudden events may include, for example, sudden fainting of a person, attacks by wild animals, etc.

[0119] In some embodiments, the terminal can detect the surrounding environment in real time and determine whether a first event has occurred based on the detection results. For example, the terminal can use a camera to detect the surrounding environment in real time, and determine that a first event has occurred when it detects an event such as a natural disaster, an attack, or a traffic accident. Alternatively, the terminal can use sensors to detect the user's health status, such as heart rate and body temperature, in real time, and determine that a first event has occurred when the terminal detects abnormal conditions such as an excessively high or low heart rate or an excessively high or low body temperature.

[0120] In some embodiments, the terminal can determine that a first event has occurred based on a first instruction. This first instruction may be manually triggered. In some embodiments, the first instruction is triggered when a first button on the terminal is used for a first operation. The first button may be, for example, an "emergency SOS button" or a "SOS button," and the first operation may be, for example, pressing or double-clicking. In some embodiments, the first instruction is triggered when the terminal detects a first preset voice. Optionally, the first preset voice may be, for example, "emergency SOS," "SOS," or "Help!" In some embodiments, to prevent the first instruction from being accidentally triggered, the first instruction may be triggered when the terminal detects a preset number of first preset voices, or when the terminal's first button is used for a preset number of first operations. Optionally, when the first instruction is triggered, the terminal determines that a first event has occurred.

[0121] Step 2102: The network device configures one or more first resource sets to the terminal.

[0122] In some embodiments, the network device may pre-configure one or more first resource sets to the terminal. In some embodiments, the network device may send second information to the terminal, which can be used to configure one or more first resource sets. In some embodiments, the second information may include broadcast signaling. Optionally, when the network device configures one or more first resource sets via broadcast signaling, different terminals within the cell can share the one or more first resource sets configured by the broadcast signaling. Optionally, the first resource set may be a periodic resource, and may include at least one of one or more time-domain resources and one or more frequency-domain resources. Optionally, the first resource set may be an alternative resource for transmitting the terminal's first information. In some embodiments, the first information may be used to request rescue. The first information may also be referred to as an emergency rescue request, rescue request, distress signal, emergency distress signal, emergency message, etc., and this disclosure does not specifically limit it in this way.

[0123] Optionally, the aforementioned first information can be used to indicate rescue-related information, which may include at least one of the following: the location information of the terminal; the altitude of the terminal; event-related information of the first event; information of the personnel involved in the first event; the required items; and environmental information of the environment in which the terminal is located.

[0124] Optionally, the aforementioned "location information" may include, for example, latitude and longitude information and / or Global Navigation Satellite System (GNSS) positioning information.

[0125] Optionally, the aforementioned "event-related information" may include at least one of the following: event type, event occurrence time, event duration, and event severity. Optionally, the event type may include, for example, natural disasters, medical emergencies, attacks, sudden incidents, traffic accidents, and being trapped in mountainous areas. Optionally, when the event type includes a traffic accident, the event-related information may also include at least one of the following: damaged vehicle parts and vehicle location information. Optionally, the event severity may include, for example, minor, moderate, severe, and extremely severe.

[0126] Optionally, the aforementioned "information related to the persons involved" may include at least one of the following: number of persons involved, gender, age, physical characteristics, blood type, etc. Optionally, the information related to the persons involved may be manually entered into the terminal. For example, when the first incident occurs, the information related to the persons involved may be manually entered into the terminal, or the information related to the persons involved may be manually entered into the terminal in advance.

[0127] Alternatively, the "required items" mentioned above can be understood as emergency-needed items, which may include, for example, food, warm clothing, etc.

[0128] Optionally, the aforementioned "environmental information" may include, for example, temperature and / or environmental safety hazards. Optionally, environmental safety hazards may include, for example, hazardous chemicals in the environment and / or the probability of aftershocks after an earthquake.

[0129] Optionally, in some embodiments, there may be a correspondence between resource sets and events. For example, different resource sets may correspond to different events, and a resource set may be used to send the first information of the corresponding event. For instance, suppose there are currently a first resource set #1 and a first resource set #2, where the first resource set #1 corresponds to event #1 and the first resource set #2 corresponds to event #2. Then, the first resource set #1 may be used to send the first information of event #1, and the first resource set #2 may be used to send the first information of event #2.

[0130] In some embodiments, steps 2101 and 2102 described above can be performed in an alternate order or simultaneously.

[0131] Step 2103: The terminal determines one or more first resource sets.

[0132] Optionally, the terminal may determine one or more first resource sets based on protocol agreements, and / or the terminal may determine one or more first resource sets based on second information sent by the network device. For a detailed description of this part, please refer to step 2102 above.

[0133] Optionally, in some embodiments, the terminal may also determine the correspondence between resource sets and events. For example, the terminal may determine the correspondence between resource sets and events based on protocol agreements and / or the configuration of network devices.

[0134] Step 2104: The terminal determines the second resource set.

[0135] Optionally, the second resource set can be a resource for sending the first information. The second resource set can be used to send the first information. For a detailed description of the first information, please refer to the description in step 2102 above.

[0136] In some embodiments, the terminal can determine a second resource set based on one or more first resource sets. Optionally, when there is only one first resource set, the terminal can determine that one first resource set as the second resource set. Optionally, when there are multiple first resource sets, in some embodiments, the terminal can randomly select a second resource set from multiple first resource sets. In some embodiments, the terminal can select a second resource set from multiple first resource sets based on a uniform distribution. In some embodiments, the terminal can select the first resource set with the closest time among multiple first resource sets as the second resource set, for example, the terminal can select the first resource set with the closest time to the current time among multiple first resource sets as the second resource set. In some embodiments, the terminal can select the first resource set corresponding to a first event among multiple first resource sets as the second resource set. For example, suppose there are currently first resource sets #1 and #2, where first resource set #1 corresponds to event #1 and first resource set #2 corresponds to event #2. If event #2 has occurred at the terminal, the terminal can select first resource set #2 as the second resource set.

[0137] Step 2105: The terminal sends the first information to the network device.

[0138] Optionally, in some embodiments, the terminal may send the first information based on resources in the second resource set.

[0139] Optionally, in some embodiments, when the terminal sends first information to indicate rescue-related information, the first information may include quantized values ​​of the rescue-related information. For example, for the aforementioned rescue-related information such as latitude and longitude and temperature, the first information may include their quantized values, thereby reducing the carrying resources required for the first information, such as reducing the number of bits carried by the first information and reducing communication resource overhead.

[0140] In some embodiments, the terminal can send first information via a signal. For example, the first information sent by the terminal to the network device may include a first sequence corresponding to rescue-related information of the first event. Optionally, in some embodiments, the aforementioned rescue-related information may correspond to different first sequences, and different first sequences can be used to indicate the corresponding rescue-related information. In some embodiments, multiple different first sequences can be designed, and different first sequences correspond to the information content (or value) of at least one of the aforementioned rescue-related information. For example, in some embodiments, the NTN serving cell can be partitioned, with different regions including different NTN serving cells. Different regions may correspond to different first sequences, and the location information of the serving cell where the terminal is located can be determined based on the first sequence. Alternatively, in some embodiments, different first sequences can be used to correspond to different event types, and the event type of the first event can be indicated using the first sequence. Alternatively, in some embodiments, different cyclically shifted first sequences can be used to indicate different rescue-related information. Alternatively, in some embodiments, different root sequences of the first sequence can be used to indicate different information content of the same rescue-related information. This disclosure does not specifically limit this. Optionally, in some embodiments, the first sequence may include a ZC sequence, a gold sequence, or other sequences, and this disclosure does not specifically limit this.

[0141] Optionally, by including a first sequence corresponding to the rescue-related information of the first event in the first information, the network device can determine the rescue-related information of the first event based on the first sequence in the first information after receiving the first information, so that emergency rescue can be carried out in a timely and accurate manner based on the rescue-related information.

[0142] Optionally, in some embodiments, the terminal may transmit the first information via a channel. For example, the terminal may transmit the first information via first signaling and / or the user plane.

[0143] In some embodiments, the first signaling may include at least one of Non-Access Stratum (NAS) signaling, Access Stratum (AS) signaling, and Media Access Control Control Element (MAC CE) signaling. Optionally, the AS signaling may include, for example, Radio Resource Control (RRC) signaling.

[0144] In some embodiments, the first signaling can be used to send first information corresponding to a first event, or the first signaling can be used to send first information corresponding to multiple first events. Taking RRC signaling as an example, its RRC parameter design method can include the following method one and / or method two.

[0145] Optionally, in some embodiments, when the first signaling reports first information corresponding to multiple first events, the first signaling may include multiple Information Elements (IEs), with different IEs corresponding to different first events, and different IEs used to carry the first information of the corresponding first event. Taking RRC signaling as an example, when RRC signaling includes first information corresponding to multiple first events, its RRC parameter design method can be as shown in the following code. Referring to the following code, it can be seen that RRC signaling may include first information corresponding to first event A (EventA), first information corresponding to first event B (EventB), first information corresponding to first event C (EventC), etc., where EventA ::=SEQUENCE{} can be the IE corresponding to EventA, used to carry the first information of EventA, EventB ::=SEQUENCE{} can be the IE corresponding to EventB, used to carry the first information of EventB, and so on.

[0146] In some embodiments, the first signaling may be different from the second signaling, and the second signaling may be used to send information other than the first information. Therefore, this disclosure defines a new signaling method for sending the first information, thereby improving the transmission efficiency of the first information.

[0147] In some embodiments, the first signaling can be processed by the terminal's first layer, which may be different from the second layer. The second layer can be used to process signaling other than the first signaling. Therefore, this disclosure defines a new layer to process the first signaling, improving the processing efficiency of the first signaling and thus improving the transmission efficiency of the first information.

[0148] In some embodiments, the service type corresponding to the first information can be a first service type, such as an emergency service type. Optionally, the first service type is different from the second service type, and the second service type can be the service type corresponding to information other than the first information. Therefore, this embodiment of the disclosure defines a new service type for the first information to distinguish it from other information, thereby improving the transmission efficiency of the first information.

[0149] In some embodiments, the first information may correspond to a first Quality of Service (QoS) requirement. This first QoS requirement may differ from a second QoS requirement, which may be a QoS requirement corresponding to information other than the first information. For example, the packet error rate (PER) of the first QoS requirement may be lower than the PER of the second QoS requirement, and the priority level of the first QoS requirement may be higher than that of the second QoS requirement. Therefore, this disclosure embodiment defines a new QoS requirement for the first information to improve its transmission efficiency.

[0150] In some embodiments, the first information may correspond to a first transmission reliability requirement, which may be different from a second transmission reliability requirement. The second transmission reliability requirement may be a transmission reliability requirement corresponding to information other than the first information. Optionally, the first transmission reliability requirement may be higher than the second transmission reliability requirement. Thus, it can be seen that the embodiments of this disclosure define a new transmission reliability requirement for the first information to improve the transmission reliability of the first information.

[0151] Optionally, in some embodiments, when the terminal uses the channel to send the first information, the channel structure design of the channel can be similar to that of other signals (such as the NR Physical Broadcast Channel (PBCH)). For example, the first information can be repeatedly transmitted K times within a resource block. For instance, the encoded bits of the first information can be repeatedly transmitted K times within a resource block, where K>1 and K is an integer.

[0152] In summary, the above embodiments provide a rescue request method for requesting emergency rescue. This method enables users to request emergency rescue when a first event occurs in uninhabited areas, remote mountainous regions, or other countries with insufficient coverage by terrestrial network (TN) base stations, such as natural disasters, medical emergencies, sudden incidents, traffic accidents, or being trapped in mountainous areas. This ensures the timeliness of rescue and guarantees user safety.

[0153] The rescue request method disclosed in this embodiment may include at least one of steps 2101 to 2105. For example, step 2101 may be implemented as a standalone embodiment, step 2105 may be implemented as a standalone embodiment, and steps 2101+2105 may be implemented as standalone embodiments, but are not limited thereto.

[0154] In some embodiments, steps 2101 and 2102 may be performed in an interchangeable order or simultaneously.

[0155] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0156] Figure 2B is an interactive schematic diagram of a rescue request method according to an embodiment of the present disclosure. As shown in Figure 2B, this embodiment of the disclosure relates to a rescue request method for a communication system 100; the method includes:

[0157] Step 2201: The terminal determines that the first event has occurred.

[0158] Step 2202: The network device configures one or more first resource sets to the terminal.

[0159] Step 2203: The terminal determines one or more first resource sets.

[0160] Step 2204: The terminal determines the second resource set.

[0161] For a detailed description of steps 2201-2204, please refer to the embodiment in Figure 2A above.

[0162] Step 2205: The terminal sends the first request to the network device.

[0163] Optionally, the first request may be used to request the sending of the first information, or the first request may be used to inform the network device that the terminal is about to send the first information. The first request may also be called an emergency event reporting request, an emergency distress signal request, or other names, which are not specifically limited in this disclosure.

[0164] In some embodiments, the terminal may send a first request to the network device before sending the first information. That is, the terminal sends a first request to inform the network device that it is about to send the first information. Therefore, if the network device does not receive the first request, it means the terminal will not send the first information at this time. The network device can then allocate the transmission resources for the first information to other transmissions, preventing the transmission resources from being idle, reducing spectrum waste, and improving resource utilization. Conversely, if the network device receives the first request, it means the terminal needs to send the first information. The network device will then reserve the transmission resources for the first information and will not use them for other scheduling, thereby ensuring the successful transmission of the first information and guaranteeing the timeliness of the rescue request.

[0165] Optionally, the first request may include a scheduling request (SR), or the first request may include a dedicated sequence. In some embodiments, at least one of the sending resources of the first request and the generation method of the second sequence may be agreed upon by a protocol and / or pre-configured by the network device. Optionally, the sending resources of the first request may be always-on resources. In some embodiments, always-on resources can be understood as follows: even if the terminal does not currently send the first request, the sending resources of the first request will be idle and will not be scheduled for other transmissions. Optionally, since the first request includes an SR or a second sequence, its content is relatively small, and therefore the sending resources of the first request are also small. Thus, even if the sending resources of the first request are idle, it will not lead to excessive resource waste, nor will it affect resource utilization. Furthermore, in this embodiment of the disclosure, by making the sending resource of the first request an always-on resource, it is possible to prevent the sending resource of the first request from being occupied by other transmissions, ensuring that the first request can be sent in a timely manner, thereby enabling the terminal to send the first information through the network device in a timely manner, so that the network device can reserve resources for the first information in a timely manner, ensuring the timely transmission of the first information and guaranteeing the timeliness of emergency rescue.

[0166] Optionally, in some embodiments, different events may correspond to different requests. In some embodiments, the terminal may send a first request corresponding to a first event to the network device. Based on the correspondence between events and requests and the first request, the network device can determine the event-related information of the first event. The network device can then reserve the first resource set corresponding to the first event in advance and not use it for other scheduling, ensuring that the terminal can subsequently successfully use the corresponding resource set to send the first information, thus guaranteeing the timely transmission of the first information.

[0167] In some embodiments, step 2205 may be performed before step 2202-step 2204, or step 2205 may be performed between step 2202-step 2204, or step 2205 may be performed simultaneously with any of steps 2202-step 2204, or step 2205 may be performed after step 2202-step 2204.

[0168] Optionally, when step 2205 is executed after steps 2202-2204, the terminal can select the first request to be sent based on the second resource set. In some embodiments, different resource sets can correspond to different requests. Optionally, the terminal can send the first request corresponding to the second resource set to the network device. Thus, the network device can determine the second resource set corresponding to the first request based on the correspondence between the resource set and the request and the first request. As a result, the network device can know that the sending resource of the first information is the second resource set. Therefore, the network device can reserve the second resource set in advance and not use the second resource set for other scheduling, so as to ensure that the terminal can successfully use the second resource set to send the first information in the future, thus ensuring the timely transmission of the first information.

[0169] Step 2206: The terminal sends the first information based on the first time window.

[0170] Optionally, the duration of the first time window can be configured by the network device and / or agreed upon by the protocol.

[0171] In some embodiments, after the terminal sends a first request, it can determine whether it has received a feedback message from the network device within a first time window. In some embodiments, the feedback message may include a sequence or signal associated with the first request; for example, the feedback message may be the same signal or the same sequence as the first request. Optionally, the time-frequency resources of the feedback message may be agreed upon by the protocol and / or configured by the network device. The terminal can detect whether it has received the feedback message on the time-frequency resources of the feedback message. Optionally, if no feedback message is received within the first time window, the terminal sends the first information.

[0172] In some embodiments, after the terminal sends the first request, it can determine whether it receives a feedback message from the network device within the first time window. When a feedback message is received within the first time window, it indicates that the network device allows the terminal to send the first information. At this time, the terminal can send the first information.

[0173] In some embodiments, after the terminal sends a first request, it can determine whether a feedback message from the network device has been received within a first time window. If no feedback message is received within the first time window, the terminal sends the first request again. Each time the first request is sent, the terminal determines whether a feedback message has been received within the first time window. If a feedback message is received within the first time window, the terminal can stop sending the first request and send the first information at least M time units after the feedback message reception time. If no feedback message is received, the terminal sends the first request again. Optionally, the maximum number of times the first request can be sent can be N. Optionally, in some embodiments, if the terminal receives a feedback message before sending N requests, it stops sending the first request; otherwise, it continues sending the first request until it has been sent N times and then stops sending. N > 0, N is an integer, and N can be 3 or other values.

[0174] For example, when N is 3, after the terminal sends the first request for the first time, it can determine whether it has received a feedback message from the network device within the first time window. If no feedback message is received within the first time window, the terminal can send the first request a second time. After the terminal sends the first request a second time, it can determine whether a feedback message has been received within the first time window a second time. If it is determined that no feedback message has been received within the first time window a second time, the terminal can send the first request a third time after the first duration. After the terminal sends the first request a third time, it can determine whether a feedback message has been received within the first time window a third time. If the terminal determines that a feedback message has been received within the first time window, the terminal can send the first information at least M time units after the time of receiving the feedback message, where M is a positive integer and M is related to the preparation time of the first information. For example, M can be greater than or equal to the preparation time of the first information, and M can be configured by the network device and / or agreed upon by the protocol.

[0175] Optionally, the first duration mentioned above can be determined in at least one of the following ways: network device configuration, protocol agreement, or terminal implementation-based determination. In some embodiments, the first duration can be selected by the terminal from (0,k) based on a random uniform distribution, where k can be configured by the network device and / or k can be agreed upon by the protocol.

[0176] In some embodiments, when the terminal sends the first information at least M time units after the time of receiving the feedback message, if the second resource set exists at least M time units after the time of receiving the feedback message, the terminal can send the first information based on the second resource set. If the second resource set does not exist at least M time units after the time of receiving the feedback message, or if the most recent resource set at least M time units after the time of receiving the feedback message is not the second resource set, or if the terminal does not select the second resource set, the terminal can send the first information based on the most recent first resource set at least M time units later, or the terminal can send the first information based on the most recent first resource set corresponding to the first event at least M time units later.

[0177] In some embodiments, if the second resource set is a periodic time-frequency resource, the transmission opportunity for the periodic time-frequency resource of the second resource set may not have arrived at least M time units after the reception of the feedback message. In this case, the terminal can select the most recently arrived time-frequency resource of the second resource set to send the first information. Alternatively, if the second resource set includes frequency domain resources but does not include time domain resources, the terminal can directly send the first information based on the frequency domain resources in the second resource set at least M time units after the reception of the feedback message.

[0178] Optionally, the aforementioned "time unit" may include at least one of the following: frame, half-frame, time slot, symbol, etc.

[0179] Optionally, if the terminal does not receive a feedback message after sending the first request multiple times, the terminal may send the first information or not send the first information. In some embodiments, the terminal may determine whether to send the first information based on the urgency of the first event. For example, when the urgency of the first event is high, the terminal sends the first information; when the urgency of the first event is low, the terminal may send the first information or not send the first information. In some embodiments, the terminal may also determine whether to send the first information based on the amount of information in the first information. For example, when the amount of information in the first information is large, the terminal may not send the first information; when the amount of information in the first information is small, the terminal may send the first information. Optionally, when sending the first information, the terminal may send the first information based on a previously selected second resource set, or the terminal may reselect a resource set from multiple first resource sets and send the first information based on the reselected second resource set, or the terminal may send the first information at least M time units after the end of the last first time window. For a detailed description of this part, please refer to the above description.

[0180] Optionally, in some embodiments, the network device will comprehensively consider the values ​​of M and the first time window when configuring uplink and downlink resources to ensure that the resource configuration is as reasonable as possible. Optionally, the uplink resources may include the first resource set and / or the transmission resources of the first request, and the downlink resources may include the time-frequency resources of the feedback message. In some embodiments, when configuring resources, the network device may, for example, ensure that: the first resource set still exists at least M time units after the terminal sends the first request, or that the time-frequency resources of the feedback message are located within the first time window after the terminal sends the first request.

[0181] Optionally, in some embodiments, when the terminal sends the first information, it can use a channel to send the first information. For details on how the terminal sends the first information, please refer to the embodiment in Figure 2A above.

[0182] In summary, the above embodiments provide a rescue request method for requesting emergency rescue. This method enables users to request emergency rescue when a first event occurs in uninhabited areas, remote mountainous regions, or other countries with insufficient coverage by terrestrial network (TN) base stations, such as natural disasters, medical emergencies, sudden incidents, traffic accidents, or being trapped in mountainous areas. This ensures the timeliness of rescue and guarantees user safety.

[0183] The rescue request method disclosed in this embodiment may include at least one of steps 2201 to 2206. For example, step 2205 may be implemented as a standalone embodiment, step 2206 may be implemented as a standalone embodiment, step 2205+2206 may be implemented as a standalone embodiment, and step 2201+2205+2206 may be implemented as a standalone embodiment, but is not limited thereto.

[0184] In some embodiments, steps 2201 and 2202 may be performed in an alternate order or simultaneously. Step 2205 may be performed before steps 2202-2204, or between steps 2202-2204, or simultaneously with any of steps 2202-2204, or after steps 2202-2204.

[0185] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0186] Figure 3 is a flowchart illustrating a rescue request method according to an embodiment of the present disclosure. As shown in Figure 3, this embodiment of the present disclosure relates to a rescue request method for a terminal, the method comprising:

[0187] Step 3101: Determine that the first event has occurred and send the first information to the network device.

[0188] Optionally, the first event indicates a need for rescue, and the first information is used to request rescue.

[0189] Optionally, the first information is used to indicate rescue-related information, which includes at least one of the following:

[0190] The location information of the terminal;

[0191] The altitude of the terminal;

[0192] Event-related information for the first event;

[0193] Information regarding the individuals involved in the first incident;

[0299] For a detailed description of step 4101, please refer to the above embodiment description.

[0300] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0301] The following is an exemplary description of the above method.

[0302] In the early discussions of 6G co-creation, considering the wide coverage of NTN, a typical NTN application scenario is as follows: In uninhabited areas, remote mountainous areas, and other areas where TN network base stations are insufficient, satellite communication can be considered for emergency rescue, such as natural disasters like blizzards, medical emergencies, man-made emergencies like attacks, traffic accidents, and search and rescue operations for people trapped in mountainous areas.

[0303] For the emergency rescue scenarios mentioned above, one issue to consider is what content the terminal needs to send when requesting emergency rescue and what specific transmission methods are used.

[0304] Key Point 1: In emergency rescue scenarios on 6G NTN networks, consider having the terminal send at least one of the following to the network-side equipment:

[0305] Geographic location information

[0306] For example, latitude and longitude information, or GNSS positioning information, etc.

[0307] Altitude information

[0308] event

[0309] Event types include natural disasters (mudslides, landslides, floods, etc.), medical rescue, and traffic accidents (including vehicle damage information, such as damaged parts and vehicle fault location information).

[0310] Information such as the time and / or duration of the event

[0311] Severity: Mild, Moderate, Severe, Extremely Severe, etc.

[0312] Information on the persons involved

[0313] Number of people, gender, age, physical characteristics, blood type, etc.

[0314] Items in urgent need, etc.

[0315] Other environmental information

[0316] For example, temperature, etc.

[0317] Other potential safety hazards (such as hazardous chemicals), etc.

[0318] Key Point Two: Based on Key Point One, the content is transmitted through at least one of the following methods.

[0319] Through signal transmission

[0320] Design a number of sequences, each representing a value of at least one of the above-mentioned contents. For example, partition the NTN serving cell, with each sequence representing a region or an event type. The terminal sends a specific sequence to the eNB to indicate its region or corresponding event type. For instance, the ZC sequence could be designed as a distress signal sequence for emergency rescue scenarios, with different cyclic shifts representing different regions or events. Different root sequences could also be used to represent different regions or events, or different root sequences could represent different values ​​of other parameters under the same event. Furthermore, the use of other sequences, such as the gold sequence, is not excluded.

[0321] Transmitted via channel

[0322] Bearing method

[0323] Carry via signaling

[0324] NAS signaling

[0325] AS signaling, such as RRC signaling, or it can be carried by defining a new MAC CE.

[0326] Note: In this approach, the content described in Point 1 needs to be defined in 3GPP for the bearer parameter types and values. For example, if the event type is carried through RRC signaling, the following RRC parameter design method is shown.

[0327] Furthermore, considering that different events may report different content, the reported content for each event can also be included in the corresponding event IE. One signaling design approach is shown below:

[0328] Note: In addition, for some content, such as latitude and longitude information, temperature, etc., a quantized value can be defined to reduce the number of bits carried.

[0329] Define an emergency service type as a special service transmitted through the UP plane. This could be done by defining a new emergency service type, or defining new QoS requirements (such as a new PER packet error rate, priority level, etc., with lower PER and higher priority), or defining new transmission reliability requirements.

[0330] The NAS / AS signaling can also be a newly defined signaling type, processed through a newly defined layer, etc.

[0331] Channel design

[0332] For example, a channel structure design similar to NR PBCH can be adopted, where the transmission within a resource block is a repetition of K times all coded bits (K>1).

[0333] Point 3: Optionally, for the transmission of emergency distress signals based on physical channels, in order to reduce spectrum resource waste and improve spectrum utilization efficiency, the following signaling interaction process design can be considered:

[0334] Step 1: The eNB pre-configures the time-frequency domain resources required for emergency message reporting, or the protocol presets the time-frequency domain resources required for emergency message reporting (that is, pre-configures semi-static resources to the terminal).

[0335] Configuration method: For example, it can be configured via broadcast signaling, that is, all UEs in the cell share the resources configured by the eNB.

[0336] Number of resource sets: The pre-configured resource set or the resource set preset by the protocol can be one or more.

[0337] Optionally, in response to the configuration of multiple resource sets, for the RRC signaling reporting design in point 2 or for other transmission methods, the terminal uses one resource set at a time to report one emergency message, and the reporting signaling of the emergency message is bound to the corresponding resource configuration.

[0338] Alternatively, in response to the configuration of multiple resource sets, the terminal selects one of them for emergency event reporting, for example, based on a uniform distribution, and / or selecting the time-domain resource with the most recent time.

[0339] Step 2: The terminal sends an emergency event reporting request to the eNB via an indication signal.

[0340] The indication signal may be: a dedicated SR corresponding to an emergency event report, or an emergency distress signal (such as a dedicated sequence).

[0341] Optionally, in response to the presence of multiple resource sets, the terminal randomly selects one resource for emergency event reporting. Correspondingly, there are multiple emergency distress uplink signals, each associated with a resource. The terminal uses the reporting request signal associated with the selected resource to send an emergency event reporting request.

[0342] Alternatively, in response to multiple resource sets, the terminal selects the associated resource for emergency event reporting based on the reported event type. Correspondingly, there are multiple emergency distress uplink signals, each associated with a resource and / or an event type. The terminal uses the reporting request signal associated with the selected resource or event to send an emergency event reporting request.

[0343] The time-frequency resources related to sending the emergency event reporting request, as well as sequence generation, can be pre-configured by the base station or preset by the protocol. Once the base station is configured, or if preset by the protocol, the resources corresponding to the emergency event reporting request are always-on resources.

[0344] Step 3: Further, terminal behavior can take the following two forms:

[0345] Step 3-1: After sending the emergency event reporting request, the terminal opens an emergency event reporting request time window to wait for the base station to send a feedback message. If no feedback message is received by the end of the time window, the emergency event is reported on the selected resource. The relevant parameters for receiving the feedback message are preset by the protocol or pre-configured by the base station. Once the terminal sends an emergency event reporting request, it goes to the corresponding location to receive the relevant feedback message. The feedback message may be a sequence or signal associated with the emergency event reporting request signal sent by the terminal in Step 2, for example, the same signal sent by the transmitting end.

[0346] Step 3-2: After sending the emergency event reporting request, the terminal opens an emergency reporting request time window to wait for the base station to send a feedback message. If no feedback message is received after the time window ends, the emergency event reporting request is resubmitted. Optionally, if no feedback message is received after the time window ends, the terminal randomly backs off for a period of time before resubmitting the emergency event reporting request. For example, the random backoff time can be selected from (0, k) based on a random uniform distribution, where k is preset by the protocol or indicated by the base station, or the determination of the random backoff time can also be implemented by the terminal. If the terminal receives a feedback message before the time window ends, the time window timing is terminated, and emergency event reporting is performed based on the selected resource after at least M time units (if no available resource is available after M time units, emergency event reporting is performed based on the most recent resource after M time units (optionally, the resource associated with the reported event)). M can be preset by the protocol or indicated by the base station. For example, M is preset by the protocol, and M is associated with the terminal's preparation time for the emergency event reporting channel.

[0347] The above solution proposes an information definition and transmission method for emergency communication scenarios based on NTN networks, providing services for NTN emergency communication scenarios without TN network coverage.

[0348] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0349] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0350] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
