Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an indication method, apparatus, device and storage medium. Background Technology

[0002] In non-terrestrial networks, insufficient network coverage is caused by the long distance between satellites / airborne equipment and the ground. HARQ-ACK feedback for random access messages (e.g., message 4 (Message.4, Msg.4) or message B (Message.B, Msg.B)) refers to the process where, after the base station receives and parses the terminal device identifier contained in message 3 (Message.3, Msg.3) during the random access process, it sends message 4 (Message.4, Msg.4) on the Physical Downlink Shared Channel (PDSCH). Msg.4 can also be called a contention resolution message. Currently, Msg.4 is scheduled using DCI format1_0 scrambled by TC-RNTI. This DCI currently includes the following fields: Identifier for DCI formats, Frequency domain resource assignment, and Time domain resource assignment, etc. The information storage capacity of each field may vary. After the contention is resolved successfully, the random access process is completed. If the terminal device successfully decodes Msg.4, it will send a Hybrid Automatic Repeat Request (HARQ) feedback to the network device. This feedback can be called a Hybrid Automatic Repeat Request-ACK Knowledge Message (HARQ-ACK). If it is not decoded correctly, no HARQ-ACK will be sent.

[0003] In related technologies, the HARQ-ACK feedback for random access messages cannot meet the coverage requirements, thus affecting the effectiveness of the HARQ-ACK feedback. Summary of the Invention

[0080] To facilitate understanding, the terminology used in this disclosure will be introduced first.

[0081] 1. Non-terrestrial Network (NTN)

[0082] Non-terrestrial networks refer to technologies that utilize typical satellite and high-altitude platform systems (HAPS) for network deployment. Compared to traditional terrestrial networks, non-terrestrial networks are suitable for situations where base stations cannot be built or are damaged, such as providing continuous coverage in remote mountainous areas, deserts, oceans, and forests, or for emergency communication when base stations are damaged due to disasters. Typical NTN scenarios can be summarized as: all-terrain coverage, signaling offloading, emergency communication, Internet of Things (IoT), and broadcast services.

[0083] 2. Random Access

[0084] Random access refers to the process from when a user sends a random access preamble to attempt to access the network until a basic signaling connection is established with the network. Random access is a crucial step in mobile communication systems and the final step in establishing a communication link between the terminal and the base station. Random access is divided into contention-based random access and non-contention-based random access.

[0085] 3. Radio Resource Control (RRC)

[0086] Radio resource control, also known as radio resource management (RRM) or radio resource allocation (RRA), refers to the management, control, and scheduling of radio resources through certain strategies and methods. Under the premise of meeting the requirements of quality of service, it aims to make full use of limited wireless network resources, ensure coverage of the planned area, and maximize service capacity and resource utilization.

[0087] 4. Downlink Control Information (DCI)

[0088] Downlink control information refers to the downlink control information carried by the Physical Downlink Control Channel (PDCCH) and sent from the eNB to the UE, including uplink and downlink resource allocation, HARQ information, power control, etc.

[0089] To better understand the instruction method disclosed in this embodiment, the communication system to which this embodiment applies is first described below.

[0090] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure.

[0092] The network device 101 in this disclosure is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network device.

[0093] The network device provided in this embodiment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. By adopting the CU-DU structure, the protocol layer of the network device, such as a base station, can be separated.

[0096] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0097] The indication method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings. Figure 2This is a flowchart illustrating an indication method provided in an embodiment of this disclosure, which is executed by a terminal device. The indication method in this embodiment can be applied to terminal devices, such as mobile phones, tablets with mobile communication functions, smartwatches, etc., and there are no limitations on its application.

[0098] like Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0099] S102: Receive first indication information sent by the network device, the first indication information being used to indicate the number of retransmissions of the hybrid automatic repeat request confirmation message corresponding to the random access message.

[0100] The first indication information refers to the message sent by the network device to the terminal device to indicate the number of retransmissions of the hybrid automatic retransmission request confirmation message corresponding to the random access message.

[0101] Random access refers to the process from when a user sends a random access preamble to attempt to access the network until a basic signaling connection is established with the network. Random access is divided into contention-based random access and non-contention-based random access. The random access message can be a contention resolution message during the random access process, such as message 4 (Message.4, Msg.4), or it can be message B (Message.B, Msg.B).

[0102] Among them, the Hybrid Automatic Repeat request-ACK knowledge message (HARQ-ACK) refers to the acknowledgment message sent by the terminal device to the network device after successfully decoding the random access message.

[0103] S202: Send a Hybrid Automatic Repeat Request Confirmation Message based on the first instruction information.

[0104] In this embodiment, by receiving first indication information sent by the network device, the first indication information is used to indicate the number of retransmissions of the hybrid automatic repeat request confirmation message corresponding to the random access message. By sending the hybrid automatic repeat request confirmation message according to the first indication information, the number of retransmissions of the hybrid automatic repeat request confirmation message can be accurately indicated based on the first indication information, thereby effectively improving the coverage and feedback effect of the hybrid automatic repeat request confirmation message.

[0105] This disclosure also provides an indication method, wherein the first indication information is a first indication field of the first signaling, and the first indication field is used to indicate the number of retransmissions of the hybrid automatic repeat request confirmation message. Thus, the number of retransmissions can be quickly determined based on the first signaling, thereby effectively improving the indication efficiency.

[0106] Signaling refers to messages transmitted between different links in a communication network (base stations, mobile stations / terminals, and mobile control switching centers, etc.). These links can analyze and process the messages and interact to form a series of operations and controls, which are used to ensure the effective and reliable transmission of user information. First signaling, on the other hand, refers to the signaling used to carry the first instruction information.

[0107] The first indication field refers to the field in the first signaling used to indicate the number of retransmissions.

[0108] This disclosure also provides an indication method, wherein the first signaling includes at least one of the following: Radio Resource Control (RRC) signaling and Downlink Control Information (DCI) for scheduling random access messages, thereby ensuring the indication effect of the first signaling on the number of retransmissions.

[0109] Radio Resource Control (RRC) refers to the management, control, and scheduling of wireless resources through certain strategies and methods. While meeting the requirements of quality of service, it aims to make full use of limited wireless network resources, ensure coverage of the planned area, and maximize service capacity and resource utilization.

[0110] Downlink Control Information (DCI) refers to the downlink control information carried by the Physical Downlink Control Channel (PDCCH) and sent by the base station to the UE, including uplink and downlink resource allocation, HARQ information, power control, etc.

[0111] This embodiment of the disclosure also provides an indication method, wherein the first indication information is at least one first indication field of the first signaling; the number of retransmissions of the hybrid automatic repeat request confirmation message is the value corresponding to at least one first indication field, thereby ensuring the reliability of the indication of the number of retransmissions by the first indication information.

[0112] This disclosure also provides an indication method, wherein the first indication information includes a first signaling and a second signaling; wherein the first signaling is used to indicate the number of retransmissions of at least one candidate Hybrid Automatic Repeat Request Acknowledgment Message; and the second signaling is used to indicate the number of retransmissions of a Hybrid Automatic Repeat Request Acknowledgment Message from the number of retransmissions of at least one candidate Hybrid Automatic Repeat Request Acknowledgment Message. Thus, the indication content of the first signaling and the second signaling can be effectively combined in the process of determining the number of retransmissions, so as to effectively improve the flexibility of the indication process.

[0113] The second signaling refers to the signaling used to indicate the number of retransmissions, and this second signaling is not the same as the first signaling.

[0114] This disclosure also provides an indication method. The first indication information includes predefined configuration information and a second signaling. The predefined configuration information includes the retransmission count of at least one candidate hybrid automatic repeat request acknowledgment message. The second signaling is used to indicate a first indication field, which is used to indicate the retransmission count of a hybrid automatic repeat request acknowledgment message from the retransmission counts of at least one candidate hybrid automatic repeat request acknowledgment message. Thus, the control effect of the retransmission count acquisition process can be effectively improved based on the predefined candidate retransmission counts.

[0115] This disclosure also provides an indication method, wherein the first signaling is Radio Resource Control (RRC) signaling, and / or the second signaling is Downlink Control Information (DCI) for Scheduling Random Access Messages. This can effectively improve the practicality of the first and second signaling in the indication process and effectively improve the indication effect.

[0116] Figure 3 This is a flowchart illustrating another indication method provided in this embodiment. The indication method in this embodiment can be applied in a terminal device, such as... Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0117] S103: Send a first request to the network device, the first request being used to request the network device to send first instruction information.

[0118] The first request refers to a message used to request the network device to send a first instruction message.

[0119] In this embodiment, by sending a first request to the network device, which is used to request the network device to send first indication information, a reliable triggering basis can be provided for the network device to send the first indication information, thereby effectively improving the timeliness of the network device sending the first indication information.

[0120] It is understood that this embodiment can be implemented alone or in combination with other embodiments of this disclosure. For example, this embodiment can be exemplary in combination with... Figure 2 The embodiments shown are together with the embodiments.

[0121] Figure 4 This is a flowchart illustrating another indication method provided in this embodiment. The indication method in this embodiment can be applied in a terminal device, such as... Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0122] S104: When the network type accessed by the terminal device is a preset type, send a first request to the network device.

[0123] The preset type refers to the network type that is pre-determined and suitable for sending the first request.

[0124] In this embodiment, by sending a first request to the network device when the network type accessed by the terminal device is a preset type, the timing of sending the first request can be effectively controlled based on the preset type, thereby effectively improving the practicality of the indication method.

[0125] It is understood that this embodiment can be implemented alone or in combination with other embodiments of this disclosure. For example, this embodiment can be exemplary in combination with... Figure 2 The embodiments shown are together with the embodiments.

[0126] This disclosure also provides an indication method, with the preset type including at least: non-terrestrial network (NTN). Therefore, the indication method can be executed in a timely manner when the terminal device accesses a non-terrestrial network to ensure the transmission reliability of the hybrid automatic repeat request confirmation message.

[0127] Non-terrestrial Network (NTN) refers to technologies that utilize typical satellite and high-altitude platforms (HAPs) for network deployment.

[0128] It is understandable that when a terminal device accesses a non-terrestrial network (NTN), the corresponding network device can be, for example, a satellite or other airborne device.

[0129] For example, when determining the type of network accessed, a terminal device can use a specific field in System Information Block 1 (SIB1), such as cell-barredNTN. If this field exists, it indicates that the network accessed by the terminal device is an NTN network. Alternatively, it can determine the network model by searching for frequency points. Or, it can determine the type of satellite orbit accessed, such as low Earth orbit satellites or geostationary satellites, by using satellite ephemeris information in SIB19. There are no restrictions on this.

[0130] This disclosure also provides an indication method in which the terminal device sends the first request to the network device when the reference signal received power (RSRP) of the downlink channel or signal detected by the terminal device is lower than a first threshold. Thus, the first threshold can provide a reliable triggering basis for sending the first request, thereby ensuring that the terminal device sends the first request in a timely manner.

[0131] The downlink channel refers to the channel used by network devices to transmit signals to terminal devices. The signals carried by the downlink channel can be called downlink signals.

[0132] Reference Signal Receiving Power (RSRP) is a key parameter in a communication network that represents the strength of a wireless signal and is one of the physical layer measurement requirements. It is the average signal power received on all REs (resource particles) carrying the reference signal within a certain symbol.

[0133] The first threshold refers to the threshold value configured for the reference signal received power (RSRP) of the downlink channel or signal.

[0134] This disclosure also provides an indication method, wherein the first threshold is an RSRP value, thereby effectively improving the correlation between the first threshold and the reference signal received power RSRP, so as to ensure the reliability of the comparison result between the reference signal received power RSRP and the first threshold.

[0150] S107: Receive a first request sent by the terminal device, the first request being used to send first instruction information to the terminal device.

[0151] In this embodiment, by receiving a first request sent by a terminal device, which is used to send first indication information to the terminal device, the first indication information can be quickly sent to the terminal device based on the received first request, thereby effectively improving the timeliness of sending the first indication information.

[0152] It is understood that this embodiment can be implemented alone or in combination with other embodiments of this disclosure. For example, this embodiment can be exemplary in combination with... Figure 6 The embodiments shown are together with the embodiments.

[0153] Figure 8 This is a flowchart illustrating another indication method provided in this embodiment. The indication method in this embodiment can be applied in network devices, such as... Figure 8 As shown, the method may include, but is not limited to, the following steps:

[0154] S108: Receive a hybrid automatic retransmission request confirmation message from the terminal device indicating the number of retransmissions specified by the first indication information.

[0155] In this embodiment, by receiving the hybrid automatic repeat request confirmation message that the terminal device repeatedly transmits according to the number of retransmissions indicated by the first indication information, the reception effect of the network device on the hybrid automatic repeat request confirmation message can be effectively improved.

[0156] It is understood that this embodiment can be implemented alone or in combination with other embodiments of this disclosure. For example, this embodiment can be exemplary in combination with... Figure 6 The embodiments shown are together with the embodiments.

[0157] For example, the above-mentioned instruction method can be illustrated as follows:

[0158] 1. Indicate the number of times the hybrid automatic repeat request acknowledgment message corresponding to the random access message (Msg.4) is retransmitted via signaling;

[0159] 2. Determine the number of times the Hybrid Automatic Repeat Request Acknowledgment Message is retransmitted through one or more signaling methods;

[0160] 3. In response to specified conditions, perform the above steps, where specified conditions may include: the terminal device sending a demand indication message to the network device.

[0161] The terminal can send this request information when the access network type is a preset type. The preset type includes one or more of the following: it is a non-terrestrial network, the measured RSRP is below a threshold, the power type is a non-high-power user, etc. Of course, the preset type can also be other types.

[0162] The demand indication information may be, for example, specific PRACH information or MAC information contained in Msg.3.

[0163] When determining the number of retransmissions of the Hybrid Automatic Repeat Request Acknowledgment Message through a signaling method, it can be any of the following:

[0164] The number of repeated transmissions is determined based on the first signaling. This first signaling adds a field indicating the number of repeated transmissions to a specific RRC IE (information element). This field is used to configure a repeated transmission count value; for example, the RRC IE could be PUCCH config common, RACH config common, etc. Of course, an existing RRC IE can also be reused directly; this application does not specifically limit this.

[0165] The first signaling step involves adding a field to the Downlink Control Information (DCI) used for scheduling Msg.4 (DCI Msg.4) to configure the number of retransmissions. The value represented by this field directly indicates the number of retransmissions. For example, if the newly added field is NofHARQRep, which has 4 bits, then the value of this field can represent a retransmission count of 1 to 16. Of course, existing fields in the DCI can also be reused directly; this application does not specifically limit this.

[0166] The first signaling implicitly indicates the number of repetitions through existing fields in DCI Msg.4. When one or more existing specific fields in DCI Msg.4 are set to a special value, the number of repetitions is considered to be X, where X is a predefined value; or the value of existing specific fields in DCI Msg.4 can be used to indicate the number of repetitions. For example, the high Y bit of the MCS indicates the number of repeated transmissions. For example, if Y=2, then the high two bits of the MCS field in the DCI of scheduling Msg.4 indicate the number of retransmissions.

[0167] When determining the number of retransmissions of the hybrid automatic repeat request acknowledgment message through multiple signaling methods, it can be any of the following:

[0168] Method 1) Display a set of configuration values ​​through the first signaling and display one value from this set of values ​​through the second signaling. For example, the first signaling is RRC RACH config common, and the second signaling is DCI msg.4.

[0169] For example, if the first signaling is configured with four possible number of repetitions: {1, 2, 4, 8}, then in DCI Msg.4, a specific field with 2 bits corresponds to four different values. When the specific field indicates a value of 4, it means that the number of repetitions is 8.

[0170] Method 2) Configure a set of values ​​explicitly through the first signaling and implicitly indicate one of the values ​​in the set through the second signaling. For example, if the first signaling is RRC RACH config common and the second signaling is DCI msg.4, the existing fields are retranslated, such as the high X bits of the MCS (for example, if the first signaling configures four repetition counts {1, 2, 4, 8}, then in DCIMsg.4, the 2 bits of an existing field (the two high bits of the MCS) correspond to four different values. When the value indicated by the two high bits of the MCS is 4, it means that the repetition count is 8).

[0171] Method 3) can be achieved by using a predefined set of values ​​plus a second signaling instruction to indicate one of these values. For example, if the second signaling instruction is DCI msg.4, the indication can be made through a specific field of DCI Msg.4 or by retranslating an existing field (such as the MCS field). For instance, if the predefined values ​​are {1,2,8,16}, and the high two bits of the MCS indicate a value of 4, then the number of repeated transmissions is 16.

[0172] For example, the first signaling uses a new parameter NumofMsg4HARQ-repetition to configure the number of repetitions. When this parameter is present, the two highest bits of the MCS field in DCI Msg.4 correspond to one of the four values ​​of the new parameter NumofMsg4HARQ-repetition; when this parameter is absent, the two highest bits of the MCS field in DCI Msg.4 correspond to one of the predefined values ​​{1,2,3,4}.

[0173] Method 4) is a combination of methods 2) and 3) above. If the first signaling exists, method 2) is used; if the first signaling does not exist, method 3) is used.

[0174] Of course, other combinations of the above methods may also be used, and this application does not specifically limit them.
