[0084] NTN is a key technology introduced by 5G. It provides wireless resources through network equipment such as satellites or drones, rather than ground base stations. Depending on how the satellite processes signals, it can be divided into transparent transmission mode and regeneration mode. In transparent transmission mode, as shown in Figure 1, the NTN ground station transmits the signal from the network device (gNB) to the satellite. The satellite converts the signal to the satellite frequency band and then transmits it to the terminal device (UE) via the satellite frequency band. Besides frequency conversion and signal amplification, the satellite does not demodulate the gNB signal, acting like a repeater. In regeneration mode, as shown in Figure 2, the NTN ground station transmits the gNB signal to the satellite. The satellite first demodulates and decodes the signal, then re-encodes and modulates it (a process known as regeneration), and transmits the regenerated signal via the satellite frequency band.
[0085] Table 1 below shows the satellite altitude, orbit, and satellite coverage of a typical NTN network:
[0086] Table 1
[0087] The NTN network is different from the TN network. Since the distance between the access network equipment of the NTN network and the terminal equipment is longer, the coverage performance of the access network equipment of the NTN network may be worse than that of the TN network, which may result in the terminal equipment being unable to access the NTN network.
[0088] To this end, this embodiment proposes a communication processing method and apparatus for solving the above-mentioned technical problems. The method can enable the terminal device to indicate a repetition request (repetition request) or a repetition capability (repetition capability) of the Msg4 Hybrid Automatic RepeatreQuestAcknowledgement (HARQ-ACK) message in the Msg4, so that the network device can clearly determine that the terminal device can perform multiple retransmissions of the HARQ-ACK for Msg4. The network device can then allocate corresponding resources in Msg4 according to actual needs. That is, the network device determines whether the terminal device can perform multiple retransmissions of the HARQ-ACK, the number of retransmissions, and the corresponding occupied transmission resources through Msg4. The terminal device can then perform multiple retransmissions of the HARQ-ACK for Msg4 according to the resources allocated by the network device in Msg4, thereby improving the coverage performance of the access network equipment of the NTN network and improving the success rate of the terminal device accessing the NTN network.
[0089] The communication processing method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.
[0090] FIG3 shows a structural diagram of a communication processing system according to an embodiment of the present disclosure. As shown in FIG3 , the system architecture may include a network device 11 and a terminal device 12 .
[0091] In some examples, the network device 11 may be an entity on the network side for transmitting or receiving signals. For example, the network device 11 may be a communication satellite, 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. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the network device 11. The network device 11 provided in the embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit. The CU-DU structure may be used to split the protocol layer of a network device, such as a base station, and the functions of some protocol layers are placed in the CU for centralized control, while the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.
[0092] In some examples, the terminal device 12 can be called a terminal, user equipment, mobile station (MS), mobile terminal (MT), etc. The terminal device 12 can also be a car with communication functions, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality device, an augmented reality device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal device 12.
[0093] It can be understood that the communication processing system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.
[0094] The following embodiments of the present disclosure may be applied to the communication processing system shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication processing system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, whether direct or indirect, and wired or wireless.
[0095] The embodiments of the present disclosure can be applied to satellite communications, Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5GNR, Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0096] In some examples, during the random access process, the terminal device 12 sends a Msg3 to the network device 11, where the Msg3 carries first information, and the first information can be used to indicate a Msg4 HARQ-ACK repetition request or a Msg4 HARQ-ACK repetition capability, wherein the indication information of the Msg4 HARQ-ACK repetition request can be used by the terminal device 12 to indicate to the network device 11 its request to retransmit the HARQ-ACK of Msg4 multiple times, and the indication information of the Msg4 HARQ-ACK repetition capability can be used by the terminal device 12 to indicate to the network device 11 its ability to support multiple retransmissions of the HARQ-ACK of Msg4.
[0097] The network device 11 receives Msg3 sent by the terminal device 12; according to the first information carried in Msg3, the corresponding resources are allocated in Msg4. For example, the network device 11 determines through Msg4 whether the terminal device can perform multiple retransmissions of HARQ-ACK, as well as the number of retransmissions and the corresponding occupied transmission resources. After receiving Msg4, the terminal device 12 needs to feedback HARQ-ACK to the network device 11. During this process, the terminal device 12 can determine whether to start multiple retransmissions of HARQ-ACK based on the information indicated by the network device 11 in Msg4 (that is, the corresponding resources allocated in Msg4).
[0098] This embodiment solves the problem of how to indicate the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability, so that the network device allocates corresponding resources in Msg4, thereby enabling the terminal device to retransmit the HARQ-ACK of Msg4 multiple times, thereby improving the coverage performance of the access network device of the NTN network and improving the success rate of the terminal device accessing the NTN network.
[0099] Furthermore, to illustrate the specific execution process of the above-mentioned communication processing system, FIG4 shows a timing diagram of a communication processing method according to an embodiment of the present disclosure. The method is applied to the above-mentioned communication processing system, as shown in FIG4, and may include the following steps:
[0100] Step 201: The terminal device sends Msg3 to the network device, where Msg3 carries first information.
[0101] In some embodiments, the terminal device receives the first information.
[0102] In some embodiments, the first information may be the information corresponding to Msg3 in the random access process, and the first information may be used to indicate a Msg4 HARQ-ACK repetition request or a Msg4 HARQ-ACK repetition capability, that is, the terminal device indicates to the network device that it can retransmit the HARQ-ACK of Msg4 multiple times. The indication information of the Msg4 HARQ-ACK repetition request can be used for the terminal device to indicate to the network device its request to retransmit the HARQ-ACK of Msg4 multiple times, and the indication information of the Msg4 HARQ-ACK repetition capability can be used for the terminal device to indicate to the network device its ability to support multiple retransmissions of the HARQ-ACK of Msg4.
[0103] For example, the first information may be an indication message or a signaling, etc., which is used to indicate Msg4 HARQ-ACK repetition request or Msg4 HARQ-ACK repetition capability. The network device allocates corresponding resources in Msg4 according to the first information, that is, the network device determines through Msg4 whether the terminal device can perform multiple retransmissions of HARQ-ACK, as well as the number of retransmissions and the corresponding occupied transmission resources.
[0104] In some embodiments, the first information corresponding to Msg3 sent by the terminal device to the network device does not carry a common control channel (CCCH) service data unit (SDU). This embodiment can implement how to perform a Msg4 HARQ-ACK repetition request or an indication of the Msg4 HARQ-ACK repetition capability when Msg3 does not carry a CCCH SDU.
[0105] For example, in some random access scenarios, such as the Small Data Transmission (SDT) scenario in the inactive state of the terminal device and the scenario in the connected state of the terminal device, the terminal device will not carry the CCCH SDU in the sent Msg3. In this case, in order to solve the problem of how to indicate the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability, the terminal device may carry indication information in the first information corresponding to the Msg3, and the indication information may be used to indicate the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability.
[0106] In some embodiments, the network device does not configure a physical uplink control channel (PUCCH) resource for the terminal device to send HARQ-ACK. For example, the terminal device determines whether there are dedicated PUCCH resources for sending HARQ-ACK based on a configuration (such as a network configuration or pre-configuration). The terminal device may carry the first information indicating the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability in Msg3 only when it is determined that no dedicated PUCCH resources are configured for sending HARQ-ACK.
[0107] In some embodiments, the terminal device may determine whether to send the first information for indicating the Msg4 HARQ-ACK repetition request or the first information for indicating the Msg4 HARQ-ACK repetition capability in a variety of ways, which are not limited herein. For example, the terminal device may determine based on whether the network device is configured with an RSRP threshold value for Msg4 HARQ-ACK retransmission; for another example, the terminal device may determine based on an indication sent by the network device, such as allowing the terminal device to send the first information for indicating the Msg4 HARQ-ACK repetition request or allowing the terminal device to send the first information for indicating the Msg4 HARQ-ACK repetition capability based on an indication sent by the network device.
[0108] The following describes the method provided by an embodiment of the present disclosure by taking an example in which a terminal device determines whether to send first information indicating a Msg4 HARQ-ACK repetition request or to send first information indicating a Msg4 HARQ-ACK repetition capability based on an RSRP threshold value of Msg4 HARQ-ACK retransmission.
[0109] For example, if the network device is configured with an RSRP threshold value for Msg4 HARQ-ACK retransmission, and when the downlink RSRP measured by the terminal device is lower than the configured RSRP threshold value for Msg4 HARQ-ACK retransmission, the terminal device may send the first information indicating the Msg4 HARQ-ACK repetition request in Msg3; when the downlink RSRP measured by the terminal device is higher than the configured RSRP threshold value for Msg4 HARQ-ACK retransmission, the terminal device does not send the first information indicating the Msg4 HARQ-ACK repetition request in Msg3. If the network device is not configured with an RSRP threshold value for Msg4 HARQ-ACK retransmission, the terminal device may send the first information indicating the Msg4 HARQ-ACK repetition capability in Msg3.
[0110] In this embodiment, there are multiple optional ways for the network device to configure the RSRP threshold value for Msg4 HARQ-ACK retransmission.
[0111] As an optional method, the RSRP threshold value for Msg4 HARQ-ACK retransmission can be configured through a cell switching command. Accordingly, the terminal device can receive a cell switching command, which may include first configuration information, wherein the first configuration information is used to indicate the RSRP threshold value for Msg4 HARQ-ACK retransmission.
[0112] The cell switching command may be used to instruct the switching of the serving cell. When the terminal device switches the serving cell, the corresponding network device may or may not change. In some examples, the serving cell switching may be switching from a TN network to an NTN network.
[0113] The cell switching command is sent by the target network device (the network device corresponding to the switching after the switching) to the terminal device through the source network device (the network device corresponding to the switching before the switching). For example, network device A (the network device corresponding to the switching after the cell) sends a cell switching command to the terminal device in the RRC connection state through network device B (the network device corresponding to the switching before the cell). The cell switching command may include first configuration information for indicating the RSRP threshold value for the retransmission of Msg4 HARQ-ACK. In the process of the terminal device randomly accessing network device A, based on the RSRP threshold value for the retransmission of Msg4 HARQ-ACK configured in the cell switching command, when the downlink RSRP measured by the terminal device is lower than the configured RSRP threshold value, the terminal device sends the first information for indicating the Msg4 HARQ-ACK repetition request in Msg3.
[0114] As another optional method, the RSRP threshold value of Msg4 HARQ-ACK retransmission can be configured through dedicated signaling. Accordingly, the terminal device can receive a first signaling (such as a dedicated signaling), and the first signaling includes a second configuration information, and the second configuration information is used to indicate the RSRP threshold value of Msg4 HARQ-ACK retransmission. For example, a terminal device in an RRC connection state can receive configuration information sent by a network device through dedicated signaling, and the configuration information can be used to indicate the RSRP threshold value of Msg4 HARQ-ACK retransmission. In the process of the terminal device randomly accessing the network device, based on the RSRP threshold value of the Msg4 HARQ-ACK retransmission configured in the first signaling, when the downlink RSRP measured by the terminal device is lower than the configured RSRP threshold value, the terminal device sends the first information for indicating the Msg4 HARQ-ACK repetition request in Msg3.
[0115] As another optional approach, the RSRP threshold for Msg4 HARQ-ACK retransmission may be configured via a system message, such as an SIB. Accordingly, the terminal device may receive a system message, which may include third configuration information, where the third configuration information is used to indicate the RSRP threshold for Msg4 HARQ-ACK retransmission. For example, before or after determining a network device to access, the terminal device receives a system message sent by the network device; and then determines the RSRP threshold for Msg4 HARQ-ACK retransmission based on the system message.
[0116] For example, during the process of the terminal device randomly accessing the network device, based on the RSRP threshold value of Msg4 HARQ-ACK retransmission configured in the system message, when the downlink RSRP measured by the terminal device is lower than the configured RSRP threshold value, the terminal device sends the first information indicating the Msg4 HARQ-ACK repetition request in Msg3.
[0117] In some examples, if the RSRP threshold value for Msg4 HARQ-ACK retransmission is configured through dedicated signaling, the RSRP threshold value configured by the dedicated signaling is used, and if the network device does not configure the RSRP threshold value through dedicated signaling, the terminal device in the RRC connection state may not indicate the Msg4 HARQ-ACK repetition request through Msg3. Or if the network device does not configure the RSRP threshold value through dedicated signaling, but the RSRP threshold value is configured in the system message, the terminal device may use the RSRP threshold value for Msg4 HARQ-ACK retransmission configured in the system message. Or, if the network device does not configure the RSRP threshold value through dedicated signaling, nor does it configure the RSRP threshold value through a system message, the terminal device in the RRC connection state may not indicate the Msg4 HARQ-ACK repetition request through Msg3.
[0118] In some embodiments, the RSRP threshold value for the retransmission of Msg4 HARQ-ACK configured by the network device may be configured after determining the capability information of the terminal device, such as by sending a cell handover command, a first signaling, or a system message. The capability information may include: the terminal device indicating to the network device its capability to support multiple retransmissions of the HARQ-ACK for Msg4.
[0119] In some embodiments, if the terminal device is not configured with an RSRP threshold value for Msg4 HARQ-ACK retransmission, the terminal device may send first information indicating the Msg4 HARQ-ACK repetition capability in Msg3. Of course, in order to meet different needs, if the RSRP threshold value for Msg4 HARQ-ACK retransmission is not configured, the terminal device may not send the first information indicating the Msg4 HARQ-ACK repetition capability in Msg3. The specific implementation may be determined according to actual conditions and is not limited in this embodiment.
[0120] It is described above that whether to send the first information for indicating the Msg4 HARQ-ACK repetition request or the first information for indicating the Msg4 HARQ-ACK repetition capability can be determined based on whether the network device is configured with the RSRP threshold value for the Msg4 HARQ-ACK retransmission. In addition, in some embodiments, the terminal device may also determine whether to send the first information for indicating the Msg4 HARQ-ACK repetition request based on the indication of the network device. Accordingly, the method of this embodiment may include: the terminal device receives a second signaling (such as a dedicated signaling), and the second signaling may include a second information, which may specifically be an indication information, etc. The second information can be used to determine whether the terminal device in the RRC connection state is allowed to indicate the Msg4 HARQ-ACK repetition request.
[0121] For example, a terminal device in an RRC connected state can determine, based on the indication information sent by the network device through dedicated signaling, that the network device allows it to indicate a Msg4 HARQ-ACK repetition request. In this way, when the downlink RSRP measured by the terminal device is lower than the RSRP threshold value configured for Msg4 HARQ-ACK retransmission, the terminal device sends the first information for indicating the Msg4 HARQ-ACK repetition request in Msg3. However, if the terminal device in an RRC connected state determines, based on the indication information sent by the network device through dedicated signaling, that the network device does not allow it to indicate a Msg4 HARQ-ACK repetition request, then even if the downlink RSRP measured by the terminal device is lower than the RSRP threshold value configured for Msg4 HARQ-ACK retransmission, the terminal device cannot send the first information for indicating the Msg4 HARQ-ACK repetition request.
[0122] In some embodiments, the method of this embodiment may include: the terminal device may send capability indication information to the network device, and the capability indication information may include whether the terminal device supports Msg4 HARQ-ACK retransmission. For example, the terminal device in the RRC connection state sends capability indication information to the network device through an RRC message (such as UECapabilityInformation), and the information may include whether the terminal device in the RRC connection state supports HARQ-ACK retransmission for Msg4. If the terminal device supports this capability, the network device allocates corresponding resources in Msg4 according to its capability. For example, the network device determines through Msg4 that the terminal device can perform multiple retransmissions of HARQ-ACK, as well as the number of retransmissions and the corresponding occupied transmission resources, etc. The terminal device may start multiple retransmissions of HARQ-ACK according to the information indicated by the network device in Msg4.
[0123] In some embodiments, in order to meet more practical needs, the terminal device in the RRC connection state may not indicate through Msg3 whether it supports the capability information of Msg4 HARQ-ACK retransmission, etc. The specific information may be determined according to actual needs, and this embodiment does not limit this.
[0124] For this embodiment, to illustrate the specific form of the first information sent by the terminal device in Msg3, in some embodiments, the C-RNTI MAC CE in the Msg3 may carry the first information. The terminal device may indicate a Msg4 HARQ-ACK repetition request or a Msg4 HARQ-ACK repetition capability through the first information carried in the C-RNTI MAC CE in the Msg3.
[0125] In some examples, the terminal device may carry the first information in the MAC sub-header of the C-RNTI MAC CE, and there are multiple optional methods.
[0126] As an optional method, the terminal device may use the reserved bits in the MAC sub-header of the C-RNTI MAC CE to carry the first information. For example, as shown in Figure 5, it is a schematic diagram of the MAC sub-header of the C-RNTI MAC CE, where R represents a reserved bit and LCID represents a logical channel identifier. This embodiment may use one of the R bits to carry the first information, such as 1 represents indicating Msg4 HARQ-ACK repetition request, and 0 represents indicating Msg4 HARQ-ACK repetition capability; or 1 represents indicating Msg4 HARQ-ACK repetition capability, and 0 represents indicating Msg4 HARQ-ACK repetition request.
[0127] In addition, as another optional method, the terminal device can also use the LCID in the MAC sub-header of the C-RNTI MAC CE to carry the first information.
[0128] For example, the terminal device uses a new LCID to identify the C-RNTI MAC CE. The existing protocol indicates that the MAC sub-PDU carries the C-RNTI MAC CE by indicating LCID=58 in the MAC sub-header. The C-RNTI MAC CE can be indicated by selecting one of the currently reserved LCIDs (37 to 42). When the selected LCID is used to identify the C-RNTI MAC CE, it indicates that the terminal device indicates the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability. If the previous LCID=58 is used to indicate the C-RNTI MAC CE, it means that the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability is not indicated.
[0129] It should be noted that the method of this embodiment is applicable to the random access scenario triggered by beam failure recovery (Beam Failure Recovery, BFR), or the random access scenario triggered by scheduling request (Scheduling Request, SR), or the random access scenario triggered by small data transmission (small data transmission, SDT) in the inactive state, or the random access scenario during cell switching, or the random access scenario during the addition or replacement of the secondary cell group (Secondary Cell Group, SCG), etc., and this embodiment does not limit it.
[0130] Step 202: The network device sends Msg4 to the terminal device according to the first information.
[0131] The network device calls the corresponding resources based on the first information carried in Msg3 and sends Msg4 to the terminal device. Msg4 may carry information such as whether the terminal device can perform multiple retransmissions of HARQ-ACK, the number of retransmissions and the corresponding occupied transmission resources (time-frequency domain resources). The occupied transmission resources may be reserved uplink HARQ-ACK resources.
[0132] Step 203: The terminal device retransmits the HARQ-ACK of Msg4 multiple times.
[0133] The terminal device receives Msg4 sent by the network device and sends a HARQ-ACK for Msg4 to the network device. According to the information carried in Msg4 and the number of retransmissions indicated by the network device, the terminal device uses the corresponding time-frequency domain resources to retransmit the HARQ-ACK multiple times.
[0134] In some embodiments, if the terminal device successfully receives Msg4, it will send a HARQ-ACK for Msg4 to the network device, and may use the corresponding time-frequency domain resources to perform multiple retransmissions of HARQ-ACK according to the number of retransmissions indicated by the network device based on the information carried in Msg4. Msg4 may include a first part and a second part, the first part may represent the Msg4 message itself, and the second part may be the scheduling information of Msg4, which includes the transmission resource location of the Msg4 message. The information indicated by the network device, such as whether the terminal device can perform multiple retransmissions of HARQ-ACK, the number of retransmissions and the corresponding occupied transmission resources (time-frequency domain resources), may be saved in the second part of Msg4. If a decoding error occurs in the first part of Msg4, the corresponding time-frequency domain resources may be used to perform multiple retransmissions of HARQ-NACK according to the number of retransmissions indicated by the network device based on the information carried in the second part of Msg4. If the terminal device does not receive Msg4, the terminal device may not send the HARQ-ACK for Msg4 to the network device.
[0135] This embodiment solves the problem of how to indicate the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability, so that the network device allocates corresponding resources in Msg4, thereby enabling the terminal device to retransmit the HARQ-ACK of Msg4 multiple times, thereby improving the coverage performance of the access network device of the NTN network and improving the success rate of the terminal device accessing the NTN network.
[0136] To illustrate the specific execution process of the network device, Figure 6 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. When applied to the terminal device side, the method may include the following steps.
[0137] Step 301: Send Msg3 to a network device, where Msg3 carries first information.
[0138] Among them, the first information can be used to indicate the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability, that is, the terminal device indicates to the network device that it can retransmit the HARQ-ACK of Msg4 multiple times. Among them, the indication information of the Msg4 HARQ-ACK repetition request can be used for the terminal device to indicate to the network device its request for multiple retransmissions of the HARQ-ACK of Msg4, and the indication information of the Msg4 HARQ-ACK repetition capability can be used for the terminal device to indicate to the network device that it supports the ability to retransmit the HARQ-ACK of Msg4 multiple times.
[0139] The first information may be an indication information, or a signaling, etc. In some embodiments, Msg3 does not carry CCCH SDU, for example, when the terminal device is in an RRC inactive state or an RRC connected state, the Msg3 sent does not carry CCCH SDU. When Msg3 does not carry CCCH SDU, indication information is carried in Msg3 to indicate Msg4 HARQ-ACK repetition request or Msg4 HARQ-ACK repetition capability, and thus this embodiment can implement how to indicate Msg4 HARQ-ACK repetition request or Msg4 HARQ-ACK repetition capability when Msg3 does not carry CCCH SDU.
[0140] In some embodiments, the network device does not configure PUCCH resources for the terminal device to send HARQ-ACK. For example, the terminal device may carry indication information for indicating the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability in Msg3 only when no dedicated PUCCH resources are configured for sending HARQ-ACK.
[0141] Furthermore, in order to clarify whether to send the first information for indicating the Msg4 HARQ-ACK repetition request or the first information for indicating the Msg4 HARQ-ACK repetition capability, it can be determined according to whether the network device is configured with the RSRP threshold value for Msg4 HARQ-ACK retransmission. For example, when the downlink RSRP measured by the terminal device is lower than the RSRP threshold value configured for Msg4 HARQ-ACK retransmission, the terminal device carries the indication information for indicating the Msg4 HARQ-ACK repetition request in Msg3.
[0142] In this embodiment, there are multiple optional ways for the network device to configure the RSRP threshold value for Msg4 HARQ-ACK retransmission.
[0143] As an optional method, the RSRP threshold value for Msg4 HARQ-ACK retransmission can be configured through a cell switching command. Accordingly, the terminal device can receive a cell switching command, which may include first configuration information, wherein the first configuration information is used to indicate the RSRP threshold value for Msg4 HARQ-ACK retransmission.
[0144] As another optional method, the RSRP threshold value for Msg4 HARQ-ACK retransmission can be configured through dedicated signaling. Accordingly, the terminal device can receive first signaling (such as dedicated signaling), which may include second configuration information, and the second configuration information is used to indicate the RSRP threshold value for Msg4 HARQ-ACK retransmission.
[0145] As another optional method, the RSRP threshold value for Msg4 HARQ-ACK retransmission can also be configured through a system message. Accordingly, the terminal device can receive a system message, which may include third configuration information. The third configuration information is used to indicate the RSRP threshold value for Msg4 HARQ-ACK retransmission.
[0146] In some embodiments, if the terminal device is not configured with an RSRP threshold value for Msg4 HARQ-ACK retransmission, the terminal device may send first information indicating the Msg4 HARQ-ACK repetition capability in Msg3. Of course, in order to meet different actual needs, if the RSRP threshold value for Msg4 HARQ-ACK retransmission is not configured, the terminal device may not send the first information indicating the Msg4 HARQ-ACK repetition capability in Msg3. The specific implementation may be determined according to actual conditions and is not limited in this embodiment.
[0147] It is described above that whether to send the first information for indicating the Msg4 HARQ-ACK repetition request or the first information for indicating the Msg4 HARQ-ACK repetition capability can be determined based on whether the network device is configured with the RSRP threshold value for the Msg4 HARQ-ACK retransmission. In addition, in some embodiments, the terminal device may also determine whether to send the first information for indicating the Msg4 HARQ-ACK repetition request based on the instruction of the network device. Accordingly, the method of this embodiment may further include: the terminal device receives a second signaling (such as a dedicated signaling), and the second signaling may include second information, and the second information is used to determine whether the terminal device in the RRC connection state is allowed to indicate the Msg4 HARQ-ACK repetition request.
[0148] In some embodiments, the method of this embodiment may include: a terminal device in an RRC connected state sends capability indication information to a network device, where the capability indication information includes whether the terminal device supports Msg4 HARQ-ACK retransmission.
[0149] In some embodiments, a terminal device in an RRC connected state may not indicate through Msg3 whether it supports the capability information of Msg4 HARQ-ACK retransmission, etc. The specific information may depend on actual needs, and this embodiment does not limit this.
[0150] For this embodiment, in order to illustrate the specific form of the first information sent by the terminal device in Msg3, in some embodiments, the first information may be carried in the C-RNTI MAC CE in the Msg3.
[0151] In some examples, the terminal device may carry the first information in the MAC sub-header of the C-RNTI MAC CE, and there are multiple optional methods.
[0152] As an optional method, the terminal device may use the reserved bits in the MAC sub-header of the C-RNTI MAC CE to carry the first information.
[0153] In addition, as another optional method, the terminal device can also use the LCID in the MAC sub-header of the C-RNTI MAC CE to carry the first information.
[0154] It should be noted that the method of this embodiment is applicable to the scenario of random access triggered by BFR, or the scenario of random access triggered by SR, or the scenario of random access triggered by SDT in an inactive state, or the scenario of random access during cell switching, or the scenario of random access during SCG addition or replacement, etc., and this embodiment does not limit it.
[0155] For the description of the specific examples in this embodiment, please refer to the corresponding description of the embodiments in Figures 1 to 5, and will not be repeated here.
[0156] This embodiment solves the problem of how to indicate the Msg4 HARQ-ACK repetition request or the Msg4 HARQ-ACK repetition capability, so that the network device allocates corresponding resources in Msg4, thereby enabling the terminal device to retransmit the HARQ-ACK of Msg4 multiple times, thereby improving the coverage performance of the access network device of the NTN network and improving the success rate of the terminal device accessing the NTN network.
