[0155] FIG1a is a schematic diagram showing a communication system architecture according to an embodiment of the present disclosure.
[0156] As shown in FIG. 1 a , a communication system 100 includes a terminal 101 and a network device 102 .
[0157] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal 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, and at least one of a wireless terminal device in a smart home, but is not limited thereto.
[0158] In some embodiments, the network device 102 may include at least one of an access network device and a core network device.
[0159] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network.

[0160] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.
[0161] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.
[0162] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).
[0163] It can be understood that the communication 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.
[0164] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or part of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0165] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 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).
[0166] In some embodiments, when the network device configures a reference signal received power (RSRP) threshold for the terminal, and the measured RSRP is lower than the configured RSRP, the terminal supporting common PUCCH repeated transmission can report the capability of common PUCCH repeated transmission to the network device. For example, the capability can be reported through the reserved bit in the medium access control (MAC) subheader in Msg3. If the network device does not configure the RSRP threshold for the terminal, the terminal supporting common PUCCH repeated transmission can directly report the capability of common PUCCH repeated transmission to the network device. For example, the capability can be reported through the spare bit in the medium access control (MAC) subheader in Msg3.
[0167] In some embodiments, the network device can configure the number of retransmissions to the terminal via a system information block (SIB). For example, candidate values for the number of retransmissions can include {2, 4, 8}. If the terminal reports its UE capability to the network device, or sends a PUCCH retransmission request to the network device, the retransmissions configured by the network device can be performed subsequently.
[0168] In some embodiments, the network device may configure a set of transmission times to the terminal through the SIB. For example, the set of transmission times may be at least two values among the candidate values {2, 4, 8}. The index of the set of transmission times may be configured using the downlink assignment index (DAI) field in the downlink control information (DCI) in the fallback format, wherein the DCI is scrambled by the cyclic redundancy check (CRC) using a temporary cell-radio network temporary identifier (TC-RNTI). Table 1 is an exemplary table of DAI indicating the number of repeated transmissions. As shown in Table 1,
[0169] Table 1
[0170] In some embodiments, the subsequent common PUCCH after the terminal sends the Msg4 HARQ-ACK to the network device may share the same repetition transmission number indicated by the DAI field of the Msg4 DCI.
[0171] In some embodiments, a network device may configure dedicated PUCCH resources via Msg4 for transmission of uplink control information (UCI) such as HARQ-ACK after the terminal establishes an RRC connection and before the terminal reports the terminal capability message and sends the RRC reconfiguration message. For example, the dedicated PUCCH resource may be configured via a signaling in Msg4. For example, the signaling may be a masterCellGroup OCTET STRING (CONTAINING CellGroupConfig).
[0172] In some embodiments, FIG1b is a schematic diagram illustrating the interaction between a terminal and a network device according to an exemplary embodiment. The network device includes a gNB and an access and mobility management function (AMF). In step 1 of FIG1b , the terminal sends an RRC establishment request to the network device. For example, the RRC establishment request may include a cause value, and the terminal identifier may be a random value or a temporary mobile subscription identifier (TMSI). In step 2, the network device may configure the terminal for RRC establishment using Msg4. For example, the RRC establishment message may include signaling radio bearer (SRB) 1 related configuration. In step 3, the terminal sends an RRC establishment complete message to the network device. For example, the RRC establishment complete message may carry a non-access stratum (NAS) registration request. Between steps 2 and 3, or after step 3, the terminal may send a Msg4 HARQ-ACK message to the network device. Since Msg4 may include the dedicated PUCCH resource configured by the network device for the terminal, after the terminal sends the Msg4 HARQ-ACK message, until the terminal sends the RRC reconfiguration complete message to the network device in step 13 of Figure 1b, the dedicated PUCCH resource configured by the network device for transmission can be used. In Figure 1b, step 4 shows the gNB sending an initial UE message to the AMF. For example, the initial UE message may include the gNB identifier, the UE identifier, and the next generation application protocol (NGAP) identifier. Step 5 shows the sending and receiving of non-access stratum transport (downlink NAS transport) messages between the AMF and the terminal, such as the downlink NAS transport sent by the AMF to the terminal and the uplink NAS transport sent by the terminal to the AMF. Step 6 shows the AMF sending an initial context setup request message to the terminal. For example, this may include receiving a registration message.Step 7 indicates that the gNB sends an Initial Context Setup Request (SSC) command to the terminal. Step 8 indicates that the terminal sends a Security Mode Complete (SSC) message to the gNB. Step 9 indicates that the gNB sends a UE Capability Enquiry (UE Capability Enquiry) message to the terminal. Step 10 indicates that the terminal sends UE Capability Information (UE Capability Information) to the gNB. Step 11 indicates that the gNB sends a UE Radio Capability Info Indication (UE Radio Capability Info Indication) message to the AMF. Step 12 indicates that the gNB sends an RRC Reconfiguration (RRC Reconfiguration) message to the terminal, such as configuring an even-even SRB2 or receiving a registration message. Step 13 indicates that the terminal sends an RRC Reconfiguration Complete (RRC Reconfiguration Complete) message to the gNB. Step 14 indicates that the gNB sends an Initial Context Setup Response (Initial Context Setup Response) to the AMF. Step 15 indicates that the AMF sends a Packet Data Unit Session Resource Setup Request (PDU Session Resource Setup Request) to the gNB. For example, this may include a Packet Data Unit (PDU) Session Establishment Accept (SES). Step 16 indicates that the gNB sends an RRC reconfiguration message to the terminal. For example, this may include data radio bearer (DRB) configuration and NAS message transparent transmission. Step 17 indicates that the terminal sends an RRC reconfiguration complete message to the gNB. Step 18 indicates that the gNB sends a PDU session resource setup response to the AMF.
[0173] In some embodiments, PUCCH formats include PUCCH format 0 and PUCCH format 1, which are used to carry HARQ-ACK and scheduling requests (SRs), and cannot be used for channel state information (CSI) feedback. CSI feedback can only be carried via PUCCH format 2, PUCCH format 3, or PUCCH format 4. PUCCH format 2, PUCCH format 3, or PUCCH format 4 are mandatory capabilities for terminal capability signaling. For example, the gNB cannot configure the relevant features of mandatory capability signaling before the terminal capabilities are reported.
[0174] FIG2a is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2a , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:
[0175] Step S2101 , the network device 102 sends first information to the terminal 101 .
[0176] In some embodiments, the terminal 101 receives first information sent by the network device 102 .
[0177] In some embodiments, the first information is used by the terminal to determine the transmission parameters of the first physical uplink control channel (PUCCH). The transmission of the first PUCCH is located after the Msg4 hybrid automatic repeat request confirmation HARQ-ACK, and / or the transmission of the first PUCCH is located before the terminal sends the first signaling, and the first signaling includes at least one of the following: terminal capability information (UE capability signaling); terminal reconfiguration completion information (RRCReconfigurationComplete). That is, the transmission of the first PUCCH before the terminal sends the first signaling can be before the terminal sends the terminal capability information (UE capability signaling) or before the terminal sends the reconfiguration completion information (RRCReconfigurationComplete). For example, the transmission of the first PUCCH can be at all times after the terminal sends the Msg4 HARQ-ACK message to the network device. For another example, the transmission of the first PUCCH can be at all times before the terminal sends the UE capability signaling. For another example, the transmission of the first PUCCH can be at all times before the terminal sends the RRCReconfigurationComplete. For another example, the first PUCCH transmission may be after the terminal sends the Msg4 HARQ-ACK message to the network device and before the terminal sends the UE capability signaling. For another example, the first PUCCH transmission may be after the terminal sends the Msg4 HARQ-ACK message to the network device and before the terminal sends the RRCReconfigurationComplete message.
[0178] In some embodiments, the transmission of the first PUCCH is located after the Msg4 HARQ-ACK, which means that the terminal sends the first PUCCH for uplink transmission after sending the Msg4 HARQ-ACK message.
[0179] In some embodiments, the first PUCCH may be used to carry at least one of the following: a HARQ-ACK message; a scheduling request (SR) message; or channel state information (CSI). The Msg4 HARQ-ACK message may indicate feedback from the terminal to Msg4 sent by the network device. The HARQ-ACK message transmitted by the first PUCCH may indicate that after the terminal sends the Msg4 HARQ-ACK message, the network device sends other downlink messages to the terminal, and the terminal provides feedback on the other downlink messages.
[0180] In some embodiments, the terminal does not expect the network device to configure dedicated PUCCH transmission parameters to the terminal via Msg4. When the terminal does not expect the network device to configure dedicated PUCCH transmission parameters to the terminal via Msg4, the network device can configure dedicated PUCCH transmission parameters for the terminal. The terminal can transmit based on the transmission parameters of the common PUCCH, that is, the first PUCCH is the common PUCCH.
[0181] In some embodiments, the first PUCCH is a dedicated PUCCH.
[0182] In some embodiments, the name of the first information is not limited, and it can be, for example, "instruction information", "configuration information", etc.
[0183] Step S2102: Terminal 101 determines the transmission parameters of the first PUCCH.
[0184] In some embodiments, the terminal may determine the transmission parameters of the first PUCCH in at least one of the following ways: determining the transmission parameters of the first PUCCH based on provisions in the protocol; receiving first information, the first information being used by the terminal to determine the transmission parameters of the first PUCCH.
[0185] In some embodiments, the terminal may receive the first information and determine the transmission parameters of the first PUCCH according to the first information.
[0186] In some embodiments, the terminal may determine the transmission parameters of the first PUCCH based on the provisions of the protocol. For example, the terminal may not receive the first information, or when the terminal does not receive the first information, the terminal may determine the transmission parameters of the first PUCCH based on the provisions of the protocol. For another example, even if the terminal receives the first information, the terminal may still determine the transmission parameters of the first PUCCH based on the provisions of the protocol.
[0187] Step S2103 , the network device 102 sends second information to the terminal 101 .
[0188] In some embodiments, the terminal 101 may receive second information sent by the network device 102 .
[0189] In some embodiments, the second information is used to semi-statically configure repetition transmission parameters of a dedicated PUCCH.
[0190] In some embodiments, the terminal may determine the repetition transmission parameter of the dedicated PUCCH after receiving the second information sent by the network device.
[0191] In some embodiments, the second information may be carried based on at least one of the following: a system message SIB; Msg4.
[0192] In some embodiments, the second information may be carried based on a SIB, and the terminal may determine the repetition transmission parameter of the dedicated PUCCH based on the SIB.
[0193] In some embodiments, the second information may be carried based on Msg4, and the terminal may determine the repetition transmission parameter of the dedicated PUCCH based on Msg4.
[0194] In some embodiments, the second information may be carried based on the SIB and Msg4. That is, the SIB and Msg4 respectively carry the second information, and the terminal may determine the repetition transmission parameter of the dedicated PUCCH based on the SIB or Msg4. For example, the repetition transmission parameter of the dedicated PUCCH may be determined preferentially based on Msg4.
[0195] In some embodiments, the name of the second information is not limited, and it can be, for example, "configuration information", "instruction information", etc.
[0196] In step S2104, the terminal 101 determines the repetition transmission parameter of the first PUCCH.
[0197] In some embodiments, when the first PUCCH is a common PUCCH, the repetition transmission parameter of the common PUCCH may be configured by sending a Msg4 HARQ-ACK message to the network device at the end, and then there is no need to configure the repetition transmission parameter for the first PUCCH. The repetition transmission parameter of the common PUCCH may also be not configured by sending a Msg4 HARQ-ACK message to the network device at the end, and the terminal can determine the repetition transmission parameter of the first PUCCH.
[0198] In some embodiments, the first PUCCH is a dedicated PUCCH.
[0199] In some embodiments, when the first PUCCH is a dedicated PUCCH, the terminal may determine a repetition transmission parameter of the first PUCCH.
[0200] In some embodiments, the repetition transmission parameter may include at least one of the following: the number of repetition transmissions; a set of repetition transmission numbers; an RSRP threshold value, where the RSRP threshold value is used by the terminal to determine whether to perform repetition transmission.
[0201] In some embodiments, when the repetition transmission parameter includes a repetition transmission count, the terminal may perform repetition transmission based on the repetition transmission count. When the repetition transmission parameter is a repetition transmission parameter set, the terminal may determine any repetition transmission count from the repetition transmission parameter set for repetition transmission. Alternatively, the terminal may receive an instruction from a network device and, based on the instruction, determine to use a repetition transmission parameter from the repetition transmission set.
[0202] In some embodiments, an RSRP threshold value is used by a terminal to determine whether to perform repeated transmissions. For example, when a network device configures an RSRP value for a terminal, the terminal determines to perform repeated transmissions when the RSRP measured value is lower than the RSRP threshold value. When the RSRP measured value is higher than the RSRP threshold value, the terminal determines not to perform repeated transmissions. The RSRP measured value represents the RSRP value measured by the terminal.
[0203] In some embodiments, when the first PUCCH is a dedicated PUCCH, the terminal may determine that the repetition transmission parameter of the dedicated PUCCH is the same as the repetition transmission parameter used by the terminal to send the Msg4 HARQ-ACK message.
[0204] In some embodiments, the repetition transmission parameter used by the terminal to send the Msg4 HARQ-ACK message can be, for example, indicated by the gNB through the DAI field in the DCI, or it can be a separate value configured by system information block 1 (SIB1).
[0205] In some embodiments, the terminal may determine the repetition transmission parameter of the dedicated PUCCH based on second information sent by the network device, where the second information is used to semi-statically configure the repetition transmission parameter of the dedicated PUCCH.
[0206] In some embodiments, determining the repetition transmission parameters of the dedicated PUCCH satisfies at least one of the following priority relationships: determining the repetition transmission parameters of the dedicated PUCCH based on Msg4 takes precedence over determining the repetition transmission parameters of the dedicated PUCCH based on SIB; determining the repetition transmission parameters of the dedicated PUCCH based on SIB takes precedence over determining that the repetition transmission parameters of the dedicated PUCCH are the same as the repetition transmission parameters used by the terminal to send the Msg4 HARQ-ACK message.
[0207] In some embodiments, when the network device does not send the second information to the terminal, the terminal may determine that the repetition transmission parameter of the dedicated PUCCH is the same as the repetition transmission parameter used by the terminal to send the Msg4 HARQ-ACK message. When the network device sends the second information to the terminal, and the second information is carried based on Msg4, the repetition transmission parameter of the dedicated PUCCH may be determined based on Msg4. When the network device sends the second information to the terminal, and the second information is carried based on SIB, the repetition transmission parameter of the dedicated PUCCH may be determined based on SIB. When the network device sends the second information to the terminal, and both Msg4 and SIB carry the second information, the terminal may preferentially determine the repetition transmission parameter of the dedicated PUCCH based on Msg4.
[0208] In some embodiments, when the network device sends the second information to the terminal, and the second information is carried based on the SIB, it can also be determined that the repetition transmission parameter of the dedicated PUCCH is the same as the repetition transmission parameter used by the terminal to send the Msg4 HARQ-ACK message.
[0209] In some embodiments, repeated transmission is performed based on the repeated transmission parameter when at least one of the following conditions is met: the terminal sends a repeated transmission capability indication to the network device; the terminal sends a repeated transmission request to the network device.
[0210] In some embodiments, when a terminal sends a retransmission capability indication to a network device, that is, notifies the network device that the terminal has the capability to perform retransmission, the terminal may perform retransmission based on the determined retransmission parameters. For example, retransmission may be performed based on the common PUCCH. In another example, retransmission may be performed based on the dedicated PUCCH.
[0211] In some embodiments, when a terminal sends a repeat transmission request to a network device, it implicitly indicates that the terminal has the capability to perform repeat transmission and requests repeat transmission. The terminal may perform repeat transmission based on the determined repeat transmission parameters. For example, repeat transmission may be performed based on the common PUCCH. In another example, repeat transmission may be performed based on the dedicated PUCCH.
[0212] In some embodiments, based on the same or different methods, the repetition transmission parameters of the dedicated PUCCH scheduled by the downlink control information DCI in the fallback format and the repetition transmission parameters of the dedicated PUCCH scheduled by the DCI in the non-fallback format are determined; the repetition transmission parameters corresponding to the dedicated PUCCH scheduled by the DCI in the fallback format are the same as or different from the repetition transmission parameters corresponding to the dedicated PUCCH scheduled by the DCI in the non-fallback format.
[0213] For example, for the dedicated PUCCH scheduled by the DCI in the fallback format and the dedicated PUCCH scheduled by the DCI in the non-fallback format, it can be determined that the repetition transmission parameters of the two dedicated PUCCHs are the same as the repetition transmission parameters used by the terminal to send the Msg4 HARQ-ACK message. Or the repetition transmission parameters of the two dedicated PUCCHs can be determined based on Msg4, or the repetition transmission parameters of the two dedicated PUCCHs can be determined based on SIB. For another example, for the DCI in the non-fallback format, the repetition transmission parameters of the dedicated PUCCH can be determined based on Msg4. The repetition transmission parameters determined by the two methods can be the same or different. For another example, the repetition transmission parameters for the dedicated PUCCH scheduled by the DCI in the fallback format can be determined based on Msg4, and the repetition transmission parameters for the dedicated PUCCH scheduled by the DCI in the non-fallback format can be determined based on SIB. This disclosure does not list them one by one, but it is understandable that the dedicated PUCCH scheduled by the fallback format DCI and the dedicated PUCCH scheduled by the non-fallback format DCI can determine the dedicated PUCCH retransmission parameters based on any same or different methods, and this disclosure does not limit them.
[0214] In some embodiments, repeated transmission is not performed if at least one of the following is satisfied: the terminal does not perform repeated transmission when sending the Msg4 HARQ-ACK message; the second information is not received.
[0215] In some embodiments, when a terminal does not perform repeated transmission when sending a Msg4 HARQ-ACK message, the terminal determines not to perform repeated transmission. The case where the terminal does not perform repeated transmission when sending a Msg4 HARQ-ACK message may be, for example, when the terminal uses a common PUCCH to send the Msg4 HARQ-ACK message and the terminal does not support repeated transmission of the common PUCCH. Alternatively, when the terminal supports repeated transmission of the common PUCCH but the RSRP measurement value is greater than the RSRP threshold corresponding to the common PUCCH, the terminal does not perform repeated transmission when sending the Msg4 HARQ-ACK message.
[0216] In some embodiments, when the terminal does not perform repeated transmission when sending the Msg4 HARQ-ACK message, but the network device configures the common PUCCH repeated transmission parameters for the terminal, the terminal can determine the dedicated PUCCH repeated transmission parameters based on the common PUCCH repeated transmission parameters configured by the network device, and perform repeated transmission based on the repeated transmission parameters.
[0217] In some embodiments, when the terminal does not receive the second information, retransmission is not performed.
[0218] In some embodiments, when the terminal sends a Msg4 HARQ-ACK message, no retransmission is performed and no second information is received, no retransmission is performed. Alternatively, when the terminal does not receive a common PUCCH retransmission parameter configured by the network device and does not receive the second information, no retransmission is performed.
[0219] Step S2105: Send the first PUCCH based on the transmission parameters of the first PUCCH.
[0220] In some embodiments, when the first PUCCH is a common PUCCH, transmission may be performed based on the transmission parameters of the commom PUCCH; when the first PUCCH is a dedicated PUCCH, transmission may be performed based on the transmission parameters of the dedicated PUCCH.
[0221] In some embodiments, a repetition transmission parameter of the first PUCCH may be determined. For detailed implementation, reference may be made to the implementation of step S2103 and step S2104, which will not be described in detail herein.
[0222] In some embodiments, repeated transmission can be performed based on the determined transmission parameters of the first PUCCH and the determined repeated transmission parameters of the first PUCCH. The transmission parameters of the first PUCCH can be understood as various parameters used to send the first PUCCH, including but not limited to the frequency domain and time domain for sending the first PUCCH. The transmission parameters of the first PUCCH can also be understood as the resources for the network device to configure the first PUCCH to the terminal. The repeated transmission parameters of the first PUCCH are used for repeated transmission to achieve coverage enhancement. For example, the repeated transmission parameters of the first PUCCH may include the number of repeated transmissions, the set of repeated transmission times, the threshold value of RSRP, etc.
[0223] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2105. For example, steps S2102 and S2105 may be implemented as independent embodiments, and step S2104 may be implemented as an independent embodiment, but is not limited thereto.
[0224] In some embodiments, step S2101 and step S2103 may be executed in an interchanged order or simultaneously.
[0225] In some embodiments, step S2101 and step S2103 are optional, and one or more of these steps may be omitted or replaced in different embodiments.
[0226] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 a .
[0227] FIG2b is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2b , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:
[0228] Step S2201: The network device 102 sends first information to the terminal 101.
[0229] In some embodiments, the terminal 101 receives first information sent by the network device 102 .
[0230] In some embodiments, the first information is used by the terminal to determine transmission parameters of a first physical uplink control channel (PUCCH). The first PUCCH is transmitted after a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) message (Mg4), and / or the first PUCCH is transmitted before the terminal sends a first signaling message, the first signaling message including at least one of the following: UE capability signaling; and RRCReconfigurationComplete message.
[0231] The specific implementation of step S2201 can refer to the implementation of step S2101, and this disclosure will not go into details here.
[0232] Step S2202: Terminal 101 determines the transmission parameters of the first PUCCH.
[0233] In some embodiments, the terminal may determine the transmission parameters of the first PUCCH in at least one of the following ways: determining the transmission parameters of the first PUCCH based on provisions in the protocol; receiving first information, the first information being used by the terminal to determine the transmission parameters of the first PUCCH.
[0234] In some embodiments, the terminal may receive the first information and determine the transmission parameters of the first PUCCH according to the first information.
[0235] In some embodiments, the terminal may determine the transmission parameters of the first PUCCH based on the provisions of the protocol. For example, the terminal may not receive the first information, or when the terminal does not receive the first information, the terminal may determine the transmission parameters of the first PUCCH based on the provisions of the protocol. For another example, even if the terminal receives the first information, the terminal may still determine the transmission parameters of the first PUCCH based on the provisions of the protocol.
[0236] Step S2203 , the network device 102 sends a downlink DCI to the terminal 101 .
[0237] In some embodiments, the terminal 101 receives a downlink DCI sent by a network device. The downlink DCI is used to schedule a dedicated PUCCH, and the downlink DCI carries a repetition transmission parameter corresponding to the dedicated PUCCH.
[0238] In some embodiments, the terminal receives a downlink DCI and may determine a repetition transmission parameter based on the downlink DCI.
[0239] In step S2204, the terminal 101 determines the repetition transmission parameter of the first PUCCH.
[0240] In some embodiments, a terminal receives a downlink DCI and may determine a repetition parameter based on the downlink DCI, for example, by indicating the number of repetitions through the downlink DCI, or determining the number of repetitions in a set of repetition times configured by the terminal through the downlink DCI.
[0241] In some embodiments, the terminal receives a downlink DCI and, in response to the CRC of the downlink DCI being scrambled using a cell radio network temporary identifier (C-RNTI), and / or the downlink DCI being a fallback format DCI, determines the repetition transmission parameter of the dedicated PUCCH based on the downlink DCI sent by the network device in at least one of the following ways: determining the repetition transmission parameter of the dedicated PUCCH based on a first field in the downlink DCI, where the first field is a downlink allocation indication field DAI; determining the repetition transmission parameter of the dedicated PUCCH based on a second field in the downlink DCI, where the second field includes at least one of the following: a modulation and coding scheme (MCS) field; a transmit power control (TPC) field; and a PUCCH resource indicator (PRI) field.
[0242] In some embodiments, the repetition transmission parameter may be indicated based on the DAI field in the DCI.
[0243] In some embodiments, the repetition parameter of the dedicated PUCCH may be determined based on one or more bits in the MCS field in the DCI. The repetition parameter of the dedicated PUCCH may be determined based on one or more bits in the TPC field in the DCI. The repetition parameter of the dedicated PUCCH may also be determined by one or more bits in the MCS field and one or more bits in the TPC field. The repetition parameter of the dedicated PUCCH may also be determined based on one or more bits in the PRI field.
[0244] In some embodiments, the terminal receives a downlink DCI and, in response to the CRC of the downlink DCI being scrambled through the C-RNTI, and / or the downlink DCI being a non-fallback format DCI, determines the repetition transmission parameters of the dedicated PUCCH based on the downlink DCI sent by the network device in at least one of the following ways: determining the repetition transmission parameters of the dedicated PUCCH based on the third field in the downlink DCI, where the third field is a newly added field in the downlink DCI; determining the repetition transmission parameters of the dedicated PUCCH based on at least part of the bits of the second field in the downlink DCI, where the second field includes at least one of the following: an MCS field; a TPC field; or a PRI field.
[0245] In some embodiments, a new field may be added to the downlink DCI, and the repetition transmission parameter of the dedicated PUCCH may be determined based on the new field. For example, the new field may be specifically used to determine the repetition transmission parameter of the dedicated PUCCH.
[0246] In some embodiments, the repetition parameter of the dedicated PUCCH may be determined based on one or more bits in the MCS field in the DCI. The repetition parameter of the dedicated PUCCH may be determined based on one or more bits in the TPC field in the DCI. The repetition parameter of the dedicated PUCCH may also be determined by one or more bits in the MCS field and one or more bits in the TPC field. The repetition parameter of the dedicated PUCCH may also be determined based on one or more bits in the PRI field.
[0247] In some embodiments, in response to the CRC of the downlink DCI being encrypted by the C-RNTI, and / or the downlink DCI being a fallback format DCI, and / or the downlink DCI being a non-fallback format DCI, the second field includes a PRI field, and the PRI field is used to indicate a dedicated PUCCH resource, and each dedicated PUCCH resource corresponds to a repetition transmission parameter.
[0248] In some embodiments, the PRI field may be used to indicate dedicated PUCCH resources, and each dedicated PUCCH resource corresponds to a repetition transmission parameter, so as to indirectly indicate that the dedicated PUCCH resource corresponds to the repetition transmission parameter by indicating the dedicated PUCCH resource.
[0249] In some embodiments, the first field or the second field indicates a repetition transmission parameter by means of a codepoint; or, the first field or the second field indicates the number of repetition transmissions of a dedicated PUCCH by indicating a numerical set index, and the numerical set index is determined based on a repetition parameter set carried by a third information carrier.
[0250] In some embodiments, the first field or the second field may indicate a repetition parameter through a codepoint. For example, the number of repetition transmissions may be indicated through a codepoint.
[0251] In some embodiments, the first field or the second field indicates the number of repeated transmissions of the dedicated PUCCH by indicating a numerical set index. The numerical set index is determined based on a repetition parameter set carried by third information. That is, the network device can configure a set of repeated transmission times for the terminal via the third information, and can indicate the numerical set index via the first field or the second field in the downlink DCI. The numerical set index is used by the terminal to determine the number of repeated transmissions in the set of repeated transmission times, and the terminal can perform repeated transmissions based on the determined number of repeated transmissions.
[0252] In some embodiments, at least one of the following conditions is met, and the retransmission parameters of the dedicated PUCCH are determined based on the first field or the second field in the downlink DCI: sending a retransmission capability indication to the network device; sending a retransmission request to the network device; receiving third information sent by the network device, the third information including a bit for explicitly instructing the terminal to perform retransmission; receiving third information sent by the network device, the third information including a retransmission parameter.
[0253] In some embodiments, the first or second field in the DCI may or may not be used to indicate the number of dedicated PUCCH retransmissions. Taking the PRI field as an example, the PRI field may be used only to indicate PUCCH resources and not to indicate the number of dedicated PUCCH retransmissions. Alternatively, the PRI field may be used to indicate both PUCCH resources and the number of dedicated PUCCH retransmissions. Therefore, when conditions are met, the dedicated PUCCH retransmission parameter may be determined based on the first or second field in the downlink DCI.
[0254] For example, after sending a retransmission capability indication to the network device, the retransmission parameters of the dedicated PUCCH can be determined based on the first field or the second field in the downlink DCI. After receiving the retransmission capability indication sent by the terminal, the network device uses the first field or the second field in the downlink DCI to indicate the retransmission parameters of the dedicated PUCCH. For another example, after sending a retransmission request to the network device, the retransmission parameters of the dedicated PUCCH can be determined based on the first field or the second field in the downlink DCI. After receiving the retransmission request sent by the terminal, the network device uses the first field or the second field in the downlink DCI to indicate the retransmission parameters of the dedicated PUCCH. For another example, when receiving third information sent by the network device and the third information includes a bit for explicitly instructing the terminal to perform retransmission, the retransmission parameters of the dedicated PUCCH can be determined based on the first field or the second field in the downlink DCI. When the third information includes a bit for explicitly instructing the terminal to perform repeated transmission, it can be determined that the network device supports repeated transmission of the terminal's dedicated PUCCH. Then, when a downlink DCI is subsequently received, the repeated transmission parameters of the dedicated PUCCH can be determined based on the first field or the second field in the downlink DCI. For another example, the third information sent by the network device can be received, and the third information includes repeated transmission parameters, and it can be determined that the network device supports repeated transmission of the terminal's dedicated PUCCH. Then, when a downlink DCI is subsequently received, the repeated transmission parameters of the dedicated PUCCH can be determined based on the first field or the second field in the downlink DCI.

[0256] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0258] Step S2205: Send the first PUCCH based on the transmission parameters of the first PUCCH.
[0259] In some embodiments, when the first PUCCH is a common PUCCH, transmission may be performed based on the transmission parameters of the commom PUCCH; when the first PUCCH is a dedicated PUCCH, transmission may be performed based on the transmission parameters of the dedicated PUCCH.
