[0035] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0036] The technical solutions of the embodiments of the present application can be applied to Figure 1A The exemplary communication system 100 shown includes a terminal 110 and a network device 120 , wherein the terminal 110 is in communication connection with the network device 120 .

[0037] The example communication system 100 can be, for example: a Global System of Mobilecommunication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an advanced long term evolution (LTE-A) system, a New Radio (NR) system, an evolution system of the NR system, an LTE-based access to unlicensed spectrum (LTE-U) system, an NR-based access to unlicensed spectrum (NR-U) system, a Universal Mobile Telecommunication System (UMTS), a next-generation communication system or other communication systems, etc.

[0038] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), and vehicle-to-vehicle (V2V) communication, and the embodiments of the present application can also be applied to these communication systems. Optionally, the communication system in the embodiments of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, and a standalone (SA) networking scenario.

[0039] The embodiments of the present application are not limited to the spectrum to which they are applied. For example, the embodiments of the present application can be applied to both licensed and unlicensed spectrum.

[0040] The terminal 110 in the embodiment of the present application may refer to a user device, an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user apparatus. The terminal may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved public land mobile communication network (PLMN), etc. The embodiment of the present application does not limit this. Figure 1B As shown, the terminal 110 in the terminal of the embodiment of the present application may include one or more of the following components: a processor 110, a memory 120 and an input / output device 130, and the processor 110 is communicatively connected to the memory 120 and the input / output device 130 respectively.

[0041] The network device 120 in the embodiment of the present application can be a device for communicating with a terminal. The network device can be an evolved base station (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the network device can be a relay device, an access point, a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved PLMN network, one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), etc. The embodiment of the present application is not limited.

[0042] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU is responsible for processing non-real-time protocols and services, implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, implementing the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. The AAU implements some physical layer processing functions, RF processing, and active antenna-related functions. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered to be sent by the DU, or by both the DU and the AAU. It is understood that a network device can be a device that includes one or more of a CU node, a DU node, or an AAU node. In addition, the CU may be classified as a network device in an access network (radio access network, RAN), or may be classified as a network device in a core network (core network, CN), which is not limited in this application.

[0043] In an embodiment of the present application, the terminal 110 or the network device 120 includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. In addition, the embodiment of the present application does not specifically limit the specific structure of the execution subject of the method provided in the embodiment of the present application. As long as it is possible to communicate according to the method provided in the embodiment of the present application by running a program that records the code of the method provided in the embodiment of the present application, for example, the execution subject of the method provided in the embodiment of the present application can be a terminal, or a functional module in the terminal that can call and execute a program.

[0044] The definitions or explanations of the concepts and terms involved in this application are as follows.

[0045] PUCCH is a physical channel in the uplink of the NR system, which carries uplink control information. The purpose of setting up PUCCH is that when the user equipment is not scheduled, that is, when it is not allocated uplink shared channel (UL-SCH) resources, the user equipment uses PUCCH to transmit L1 / L2 control information, including channel state information (CSI) (precoding matrix indicator (PMI) and channel quality indicator (CQI), etc.), hybrid automatic repeat request (HARQ) confirmation (ACK / NACK) and scheduling request (SR).

[0046] When two or more PUCCHs overlap, the PUCCH resource to be used is determined based on the PUCCH resource set to which the total uplink control information (UCI) bits belong. In the NR system, after the radio resource control RRC connection is established, Figure 1CAs shown, a maximum of K = 4 PUCCH resource sets can be configured for a user equipment (UE). The UE determines which PUCCH resource set to use based on the UCI size required for feedback in the current slot. The UCI size range that can be carried by PUCCH resource set i (i = 0, …, K-1) is {Ni, …, Ni+1-1} bits. When multiple PUCCH resource sets are available, N0 = 1 and N1 = 3, and Ni (i = 2, …, K-1) is configured via UE-specific higher-layer signaling.

[0047] 5G NR supports a flexible TDD frame structure and can configure the network's frame structure using semi-static configuration and dynamic indication. Slot Format Related Information (SFI) is a broad concept and there are two types. One is dynamically configured by semi-static RRC signaling, namely semi-static SFI; the other is carried on the group-common Physical Downlink Control Channel (GC-PDCCH) and dynamically sent to a group of UEs, namely dynamic SFI. The SFI information carried on the GC-PDCCH can indicate the format of one or more time slots. After the UE monitors the SFI, it can know which symbols in the time slot are "UL (uplink)", which are "DL (downlink)", and which are "flexible".

[0048] 5G NR system version R15 supports flexible resource allocation in the time domain. Compared with the subframe-based scheduling of the Long Term Evolution (LTE) system, NR's scheduling in the time domain is finer in granularity and can be scheduled based on orthogonal frequency division multiplexing (OFDM) symbols. In addition, 5G NR R15 also supports repeated transmissions between time slots. The number of repeated transmissions N is configured through high-layer signaling. The physical uplink shared channel (PUSCH) is repeatedly transmitted in N time slots, and the position of the transmitted symbols is the same in each time slot. This is called PUSCH repetition type A. If at least one symbol in a time slot is a downlink symbol, the PUSCH in the current time slot is not transmitted. This may result in the number of PUSCH repetitions being less than N.

[0049] To support Ultra Reliability and Low Latency Communication (URLLC) scenarios, Rel-16 NR supports intra-slot repeated transmission (called PUSCH repetition type B), which can meet URLLC latency requirements and improve the reliability of URLLC services. Multiple intra-slot repeated transmissions can occur within a single slot or across multiple slots.

[0050] The base station informs the UE of the nominal number of retransmissions using the number of repetitions configured in the time domain resource table. When a retransmission instance spans time slots or uplink / downlink switching points, it is divided into multiple actual retransmission instances. The actual number of retransmission instances may be greater than the nominal number of retransmissions. For retransmissions scheduled by downlink control information (DCI) (including activation DCI), the DCI indicates the time domain resource allocation for the first nominal retransmission instance.

[0051] For semi-statically configured time domain resources, the time domain resource allocation for the first nominal repetition instance is configured in the time domain resource table and / or indicated via DCI. Subsequent repetition instances are inferred based on the first nominal repetition instance and the uplink and downlink frame structure configuration. The symbols available for uplink data transmission directly affect the time domain resources occupied by subsequent repetition instances. Figure 1D An example diagram of repeated PUSCH transmission in Rel-16 time slot is given, where: Figure 1D In (a), PUSCH is transmitted twice in a single time slot, and the time domain resources are continuous. Figure 1D In (b), the PUSCH is transmitted four times repeatedly within two consecutive time slots, and the time domain resources are continuous. Furthermore, in Rel-16, multiple unusable symbols may exist during repeated PUSCH transmission within a time slot. These symbols include downlink symbols semi-statically configured by higher-layer signaling, synchronization signal and PBCH block (SSB) symbols, CORESET symbols configured by the Master Information Block (MIB) or System Information Block (SIB1), the symbol interval after downlink symbols configured by higher-layer signaling, invalid symbols configured by higher-layer signaling (the specific usage is described below), and time slot boundaries.

[0052] For dynamically scheduled PUSCH repetition type B or PUSCH repetition type B with scheduling grant activated by PDCCH, if dynamic SFI is configured, a pattern indicating unavailable symbols is indicated via the first higher layer signaling, and a second higher layer signaling indicates whether the DCI has a dynamic indication bit and whether the pattern is valid. When the first higher layer signaling is not configured, all semi-static flexible symbols are available for PUSCH transmission.

[0053] If the first higher layer signaling exists and the DCI has an indication bit, then the indication bit is 0, which means that all semi-static flexible symbols can be used for PUSCH transmission. The indication bit is 1, which means that PUSCH needs to split the downlink DL and pattern symbols, and other symbols can be used for PUSCH transmission.

[0054] If the first higher layer signaling exists and the DCI does not have an indication bit, the PUSCH needs to split the DL and pattern symbols, and the other symbols can be used for PUSCH transmission.

[0055] Currently, when PUCCH is repeatedly transmitted, if the corresponding transmission slot contains at least one unusable symbol, the transmission parameters of the current PUCCH repetition cannot be determined. The flexibility and reliability are difficult to meet the requirements of new communication systems.

[0056] To address the above issues, an embodiment of the present application proposes a PUCCH repeated transmission method, which is described in detail below with reference to the accompanying drawings.

[0057] See also Figure 2A , Figure 2A 1 is a flow chart of a PUCCH repeated transmission method provided in an embodiment of the present application. As shown in the figure, the method includes:

[0058] Step 201: The terminal transmits a first PUCCH repetition using a transmission resource configuration parameter set.

[0059] Step 202: The network device receives the first PUCCH repetition transmitted by the terminal using the transmission resource configuration parameter set.

[0060] Among them, the first PUCCH repetition is the actual PUCCH repetition after segmentation processing of the normal PUCCH repetition, and the transmission resource configuration parameter set includes a first PUCCH format, which is determined according to the number of time units occupied by the actual PUCCH repetition and the number of uplink control information UCI carried by the actual PUCCH repetition.

[0061] In the specific implementation, since the PUCCH transmission contains invalid symbols (downlink symbols semi-statically configured by high-level signaling, SSB symbols, CORESET symbols configured by MIB or SIB1, symbol intervals after downlink symbols configured by high-level signaling, invalid symbols configured by high-level signaling, dynamically scheduled downlink transmissions, dynamic time slot format information), PUCCH cannot be sent within all pre-configured time domain symbols, then PUCCH can be segmented. After segmentation, some of the PUCCH repetitions cannot be sent, and some can be sent. The PUCCH that can be sent is called actual PUCCH repetition. The transmission resource configuration parameter set includes multiple PUCCH formats and other parameters required for transmitting the actual PUCCH repetition. The first PUCCH format is any one of the multiple PUCCH formats included in the transmission resource configuration parameter set. The data carried by different formats are shown in Table 1:

[0062] PUCCH format OFDM symbol length Number of digits 0 1–2 ≤2 1 4–12 ≤2 2 1–2 >2 3 4–12 >2 4 4–12 >2

[0063] Table 1

[0064] Among them, the PUCCH format includes format 0, format 1, format 2, format 3, and format 4. The OFDM symbol length shown is the number of time units occupied by the above-mentioned PUCCH repetition, which can be 1-2 symbol lengths, or 4-12 symbol lengths. The number of bits shown is the number of UCIs carried by the above-mentioned PUCCH repetitions, which can be greater than 2 bits or less than or equal to 2 bits.

[0065] It can be seen that in this example, the system uses the transmission resource configuration parameters and the actual PUCCH repetition that needs to be transmitted after transmission segmentation, and can obtain the transmission mode and related parameters of the current actual PUCCH repetition transmission configured in the transmission resource configuration parameter set, which can improve the flexibility and reliability of system resource configuration.

[0066] In this possible example, the transmission resource configuration parameter set also includes at least one of the following: time domain symbol position, frequency domain length, position and frequency domain length of the physical resource block PRB occupied by the frequency domain, orthogonal mask code OCC length and configuration of the OCC index, and position of the demodulation reference signal DMRS.

[0067] Among them, some of the various parameters included in the transmission resource configuration parameter set need to be modified compared with the normal PUCCH repetition when the actual PUCCH repetition is transmitted after the normal PUCCH repetition is segmented, and some are the same as the normal PUCCH repetition. Whether the parameters in the corresponding transmission resource configuration parameter set need to be modified depends on the PUCCH format used by the normal PUCCH repetition and the PUCCH format used by the current actual PUCCH repetition.

[0068] It can be seen that in this example, the system uses the transmission resource configuration parameters and the actual PUCCH repetition that needs to be transmitted after transmission segmentation, and can obtain the transmission mode and related parameters of the current actual PUCCH repetition transmission configured in the transmission resource configuration parameter set, which can improve the flexibility and reliability of system resource configuration.

[0069] In this possible example, when the second PUCCH format is not included in the transmission resource configuration parameter set, the first PUCCH format is the PUCCH format with the largest number of time units among the PUCCH formats in which the number of time units is less than the number of time units occupied by the actual PUCCH repetition, and the second PUCCH format is determined based on the number of time units occupied by the actual PUCCH repetition and the number of uplink control information UCI carried by the actual PUCCH repetition.

[0070] Among them, Figure 2B As shown, Figure 2BThis is a schematic diagram of an actual PUCCH repetition resource configuration provided by an embodiment of the present application. The number of time units required for normal PUCCH repetition is 11. When the number of UCI carried by the normal PUCCH repetition is greater than 2 bits, the PUCCH format used by the normal PUCCH repetition is format 3 or format 4. When the number of UCI carried by the normal PUCCH repetition is less than or equal to 2 bits, the PUCCH format used by the normal PUCCH repetition is format 1. Since the 3rd to 10th symbols in the resources required for the normal PUCCH repetition are unavailable symbols, the normal PUCCH repetition will be divided into two segments. Therefore, the part of the normal PUCCH repetition corresponding to the downlink symbol is the actual PUCCH repetition. At this time, the number of time units required for the actual PUCCH is 3. However, as shown in Table 1, there is no PUCCH format that transmits a PUCCH with a time unit number of 3. Therefore, the PUCCH format with a time unit number less than 3 and the largest number of time units is selected to transmit the actual PUCCH format. Therefore, when the number of UCIs actually carried by the PUCCH repetitions is greater than 2 bits, format 2 is selected to transmit the actual PUCCH repetitions. When the number of UCIs actually carried by the PUCCH repetitions is less than 2 bits, format 0 is selected to transmit the actual PUCCH repetitions.

[0071] It can be seen that in this example, when the transmission resource configuration parameter set does not include the second PUCCH format, the first PUCCH format is the PUCCH format with the largest number of time units among the PUCCH formats whose number of time units is less than the number of time units occupied by the actual PUCCH repetitions. This can improve the flexibility and reliability of system resource configuration.

[0072] In this possible example, when the third PUCCH format is format 3 or format 4 and is different from the first PUCCH format, and the number of UCIs carried by the actual PUCCH repetition is not less than 2 bits: the time domain symbol position includes the starting symbol position and the number of symbols corresponding to the actual PUCCH repetition; the frequency domain length of the PRB position occupied by the frequency domain is not greater than the number of PRBs configured for the normal PUCCH repetition, and the number of PRBs occupied by the frequency domain depends on the number of PRBs required after the UCI carried by the actual PUCCH repetition is encoded at the configured maximum code rate; if the third PUCCH format is format 4, the configuration of the OCC length and the OCC index is ignored; the position parameters of the demodulation reference signal DMRS are determined according to the time domain symbol position and the first PUCCH format; wherein, the third PUCCH format is determined according to the number of time units occupied by the normal PUCCH repetition and the number of UCIs carried by the normal PUCCH repetition.

[0073] Among them, as shown in the figure, Figure 2C This is another actual PUCCH repetition resource configuration diagram provided by an embodiment of the present application. The number of time units required for normal PUCCH repetition is 11. When the number of UCI carried by the normal PUCCH repetition is greater than 2 bits, the PUCCH format used by the normal PUCCH repetition is format 3 or format 4. Since the 3rd to 11th symbols are unavailable symbols, the normal PUCCH repetition needs to be segmented and transmitted. The actual PUCCH repetition after segmentation includes 2 time units. Since the number of UCI carried by the actual PUCCH repetition is greater than 2 bits at this time, the first PUCCH format used by the current actual PUCCH repetition is format 2. This makes the PUCCH format used for actual PUCCH repetition different from the format used for normal PUCCH repetition. At this time, compared with the parameters used for normal PUCCH repetition, the parameters in the transmission resource configuration parameter set that need to be modified for actual PUCCH repetition include the time domain symbol position, the position of the PRB occupied by the frequency domain, the frequency domain length, the OCC length, the configuration of the OCC index, and the position parameters of the demodulation reference signal DMRS.

[0074] As can be seen, in this example, the first PUCCH format determined based on the number of time units actually occupied by PUCCH repetitions and the number of UCIs actually carried by the PUCCH repetitions is different from the format used for normal PUCCH repetitions, and the parameters to be modified are determined based on the first PUCCH format. This can improve the flexibility and reliability of system resource configuration.

[0075] In this possible instance, when the number of PRBs required after the UCI carried by the actual PUCCH repetition is encoded at the configured maximum code rate is greater than the number of PRBs configured for the actual PUCCH repetition, and the normal PUCCH repetition carries channel state information 2CSI2, the information transmitted by the actual PUCCH repetition includes: hybrid automatic repeat request HARQ-ACK information, scheduling request SR information, and channel state information 1CSI1.

[0076] If the number of PRBs exceeds the original number, and if the UCI is greater than 2 bits, each PUCCH resource set can contain 8 resources. The 3 bits of the 3-bit PUCCH resource indicator (PRI) in the downlink control information (DCI) in the DCI indicate which PUCCH resource in the PUCCH resource set can be used. HARQ-ACK information, SR information, and CSI1 are then transmitted in the actual PUCCH repetition.

[0077] It can be seen that in this example, when the number of PRBs required after the UCI carried by the actual PUCCH repetition is encoded at the configured maximum code rate is greater than the number of PRBs configured for the actual PUCCH repetition, and the normal PUCCH repetition carries the channel state information 2CSI2, the information content of the actual PUCCH repetition transmission is determined, which can improve the flexibility and reliability of system resource configuration.

[0078] In this possible example, when the third PUCCH format is format 1 and is different from the first PUCCH format, and the number of UCIs carried by the actual PUCCH repetition is not greater than 2 bits: the time domain symbol position includes the starting symbol position and the number of symbols corresponding to the actual PUCCH repetition; the position of the physical resource block PRB occupied by the frequency domain has a frequency domain length of 1; the configuration of the OCC index is ignored; wherein the third PUCCH format is determined according to the number of time units occupied by the normal PUCCH repetition and the number of UCIs carried by the normal PUCCH repetition.

[0079] Among them, as shown in the figure, Figure 2C This is another actual PUCCH repetition resource configuration diagram provided by an embodiment of the present application. The number of time units required for normal PUCCH repetition is 11. When the number of UCI carried by the normal PUCCH repetition is less than or equal to 2 bits, the PUCCH format used by the normal PUCCH repetition is format 1. Since the 3rd to 11th symbols are unavailable symbols, the normal PUCCH repetition needs to be segmented and transmitted. The actual PUCCH repetition after segmentation includes 2 time units. Since the number of UCI carried by the actual PUCCH repetition is less than or equal to 2 bits at this time, the first PUCCH format used by the current actual PUCCH repetition is format 0. This makes the PUCCH format used for actual PUCCH repetition different from the format used for normal PUCCH repetition. At this time, compared with normal PUCCH repetition, the parameters that need to be modified during actual PUCCH repetition transmission include the time domain symbol position, the position of the physical resource block PRB occupied by the frequency domain, the frequency domain length, and the configuration of the OCC index.

[0080] As can be seen, in this example, the first PUCCH format determined based on the number of time units actually occupied by PUCCH repetitions and the number of UCIs actually carried by the PUCCH repetitions is different from the format used for normal PUCCH repetitions, and the parameters to be modified are determined based on the first PUCCH format. This can improve the flexibility and reliability of system resource configuration.

[0081] In this possible example, when the first PUCCH format is the same as the third PUCCH format: the frequency domain length of the actual PUCCH repetition is the same as the frequency domain length of the normal PUCCH repetition; the frequency domain length of the physical resource block PRB position occupied by the frequency domain is not greater than the number of PRBs configured by the original PUCCH, and the number of PRBs occupied by the frequency domain depends on the number of PRBs required after the UCI carried by the actual PUCCH repetition is encoded at the configured maximum code rate; if the third PUCCH format is format 4, the OCC length and the OCC index of the actual PUCCH repetition are the same as the OCC length and OCC index of the normal PUCCH repetition; the position of the demodulation reference signal DMRS is determined according to the time domain symbol position of the actual PUCCH repetition and the first PUCCH format; wherein, the third PUCCH format is determined according to the number of time units occupied by the normal PUCCH repetition and the number of UCI carried by the normal PUCCH repetition.

[0082] Among them, as shown in the figure, Figure 2D This is another actual PUCCH repetition resource configuration diagram provided by an embodiment of the present application. The number of time units required for normal PUCCH repetition is 11. When the number of UCIs carried by the normal PUCCH repetition is less than or equal to 2 bits, the PUCCH format used by the normal PUCCH repetition is 1. When the number of UCIs carried by the normal PUCCH repetition is greater than or equal to 2 bits, the PUCCH format used by the normal PUCCH repetition is format 3 or format 4. Since the third symbol is an unavailable symbol, the normal PUCCH repetition needs to be segmented and transmitted. The actual PUCCH repetition after segmentation includes 10 time units. Therefore, when the number of UCIs carried by the actual PUCCH repetition is less than or equal to 2 bits, the first PUCCH format used by the current actual PUCCH repetition is also format 1. When the number of UCIs carried by the actual PUCCH repetition is greater than 2 bits, the first PUCCH format used by the current actual PUCCH repetition is also format 3 or format 4. This makes the PUCCH format used by the actual PUCCH repetition the same as the format used by the normal PUCCH repetition. At this time, compared with normal PUCCH repetition, the parameters that need to be modified during actual PUCCH repetition transmission include the frequency domain length of the actual PUCCH repetition, the position of the physical resource block PRB occupied by the frequency domain, the frequency domain length, the OCC length, the configuration of the OCC index, and the position of the demodulation reference signal DMRS.

[0083] In a specific implementation, if the frequency domain length of the physical resource block PRB position occupied by the frequency domain is greater than the number of PRBs configured by the original PUCCH, when the UCI is less than or equal to 2 bits, each PUCCH resource set can contain 8 to 32 resources; when there are more than 8 resources, the 3-bit PUCCH resource indicator field (PUCCH resource indicator) in the DCI indicates which PUCCH resources (also called PUCCH resource subsets) of the PUCCH resource set can be used, and then the CCE-index-based implicit mapping method is used to determine which PUCCH resource the UE ultimately uses in the PUCCH resource subset. (CCE: control channel element). When the UCI is greater than 2 bits, each PUCCH resource set can contain 8 resources; the 3-bit PUCCH resource indicator (PRI) in the downlink control information (DCI) in the DCI indicates which PUCCH resource of the PUCCH resource set can be used, and no implicit mapping method is required.

[0084] As can be seen, in this example, the first PUCCH format determined based on the number of time units actually occupied by PUCCH repetitions and the number of UCIs actually carried by the PUCCH repetitions is the same as the format used for normal PUCCH repetitions, and the parameters to be modified are determined based on the first PUCCH format. This can improve the flexibility and reliability of system resource configuration.

[0085] In this possible example, the first PUCCH format is any one of a plurality of PUCCH formats in the transmission resource configuration parameter set.

[0086] When the PUCCH format reused by the normal PUCCH is any format in the transmission resource configuration parameter set, the first PUCCH format reused by the actual PUCCH obtained after segmenting the normal PUCCH may be the same as the format reused by the normal PUCCH.

[0087] It can be seen that in this example, when the third PUCCH format is the same as the first PUCCH format, the first PUCCH format can be any one of the multiple PUCCH formats in the transmission resource configuration parameter set, which can improve the flexibility and reliability of system resource configuration.

Figure 3 As shown, the PUCCH repetition transmission device 3 includes a transmission unit 30, and the transmission unit 30 is used to transmit the first PUCCH repetition using a transmission resource configuration parameter set; wherein, the first PUCCH repetition is the actual PUCCH repetition after segmentation processing of the normal PUCCH repetition, and the transmission resource configuration parameter set includes a first PUCCH format, and the first PUCCH format is determined according to the number of time units occupied by the actual PUCCH repetition and the number of uplink control information UCI carried by the actual PUCCH repetition.
