[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202110363575.X, filed with the State Intellectual Property Administration of China on April 2, 2021, entitled "Physical uplink control channel transmission method, receiving method, and communication device," and Chinese Patent Application No. 202111308908.5, filed with the State Intellectual Property Administration of China on November 5, 2021, entitled "Physical uplink control channel transmission method, receiving method, and communication device," both of which are incorporated herein by reference in their entirety.

[0002] The present application relates to the field of communication technologies, in particular to a physical uplink control channel (PUCCH) transmission and reception method and a communication device. [Background technology]

[0003] Normally, when a terminal device receives or transmits information within a frequency range that does not exceed the maximum channel bandwidth capability of the terminal device, frequency readjustment does not need to be performed. However, if the terminal device receives or transmits information within a frequency range that exceeds the maximum channel bandwidth capability of the terminal device, the terminal device needs to perform frequency readjustment to receive or transmit information within the larger frequency range.

[0004] For reduced-capability terminal devices, such as massive machine type communications (mMTC) devices, the bandwidth capability of the reduced-capability terminal device is limited. When the reduced-capability terminal device transmits a PUCCH in a frequency range that exceeds the maximum channel bandwidth capability of the reduced-capability terminal device, the reduced-capability terminal device requires a duration of M symbols for frequency readjustment. Therefore, the PUCCH cannot be transmitted within the adjustment duration of M symbols, causing degraded PUCCH transmission performance of the reduced-capability terminal device. In addition, if a reduced-capability terminal device and a normal terminal (e.g., an enhanced mobile broadband (eMBB) device) share a PUCCH channel on the same resource, M symbols cannot be used to transmit the PUCCH of the reduced-capability terminal device, but can be used to transmit the PUCCH of the normal terminal device, so orthogonality between the PUCCH transmission of the reduced-capability terminal device and the PUCCH transmission of the normal terminal device cannot be guaranteed. Specifically, the PUCCH transmission of the reduced-capability terminal device interferes with the PUCCH transmission of the normal terminal device, causing degraded PUCCH transmission performance of the normal terminal device. Summary of the Invention [Means for solving the problem]

[0005] This application provides a PUCCH transmitting method, a receiving method, and a communication device to reduce the degraded PUCCH transmission performance of a reduced-capability terminal device and reduce the impact of the PUCCH transmission of the reduced-capability terminal device on the PUCCH transmission of a normal device.

[0006] According to a first aspect, a PUCCH transmission method is provided. The method can be performed by a first communication device. The first communication device can be a communication device or a communication apparatus, for example, a chip system, that can support the communication device in realizing the functions required in the method. An example in which the communication device is a terminal device is used below for explanation. The method includes the following steps:

[0007] The terminal device determines a first transmission scheme from a plurality of transmission schemes and transmits the PUCCH in the first transmission scheme, where the plurality of transmission schemes includes a first non-frequency hopping transmission scheme and / or an inter-time-unit frequency hopping transmission scheme, or the plurality of transmission schemes includes a second non-frequency hopping transmission scheme and an intra-time-unit frequency hopping transmission scheme, and the plurality of transmission schemes does not include the first non-frequency hopping transmission scheme.

[0008] The first non-frequency hopping transmission scheme is to transmit the PUCCH without frequency hopping within a time unit, and the uplink control information (UCI) on the PUCCH includes a first part and a second part, the first part being transmitted by using an orthogonal sequence having a length of L1 and the second part being transmitted by using an orthogonal sequence having a length of L2; and / or to transmit the PUCCH without frequency hopping within a time unit, and the demodulation reference signal (DMRS) on the PUCCH includes a third part and a fourth part, the third part being transmitted by using an orthogonal sequence having a length of L3 and the fourth part being transmitted by using an orthogonal sequence having a length of L4, where Li (i=1, 2, 3, or 4) is a positive integer.

[0009] The inter-time unit frequency hopping transmission scheme is to transmit the first hop of the PUCCH by using F symbols in the nth time unit and the second hop of the PUCCH by using LF symbols in the (n+1)th time unit. The length of the PUCCH is L symbols, and there is an interval of 14-F symbols between the last symbol of the F symbols and the first symbol of the LF symbols, where F and L are positive integers.

[0010] The second non-frequency hopping transmission scheme is to transmit the PUCCH without frequency hopping within a time unit, in which the UCI on the PUCCH is transmitted by using an orthogonal sequence having a length of L5, and the DMRS on the PUCCH is transmitted by using an orthogonal sequence having a length of L6, where L (i=5 or 6) is an integer.

[0011] The intra-time-unit frequency hopping transmission method transmits the PUCCH using frequency hopping within a time unit.

[0012] In this embodiment of the present application, two new PUCCH transmission schemes, namely, a first non-frequency hopping transmission scheme and an inter-time-unit frequency hopping transmission scheme, are additionally provided based on the second non-frequency hopping transmission scheme and the intra-time-unit frequency hopping transmission scheme. For the inter-time-unit frequency hopping transmission scheme, a specific number of symbols is specified between the first and second hops of the PUCCH, and the specific number of symbols can be used for frequency readjustment. In this way, even if a reduced-capability terminal device transmits or receives a PUCCH within a frequency range that exceeds the maximum channel bandwidth capability of the reduced-capability terminal device, frequency readjustment can be performed within the specific number of symbols, and PUCCH transmission is not affected. In this way, degraded PUCCH transmission performance of the reduced-capability terminal device can be avoided. For the first non-frequency hopping transmission scheme, the UCI and DMRS on the PUCCH are separately divided into two parts, so that the UCI and DMRS are transmitted without frequency hopping by using orthogonal sequences with the same or different lengths. Even if a normal terminal device and a reduced capability terminal device share a PUCCH resource, the normal terminal device and the reduced capability terminal device can still use orthogonal sequences for PUCCH transmission to avoid interference with the PUCCH transmission of the normal device and ensure the PUCCH transmission performance of the normal terminal device.

[0013] In possible implementations, the plurality of transmission schemes may include a first non-frequency hopping transmission scheme and a second non-frequency hopping transmission scheme, or may include a first non-frequency hopping transmission scheme and an intra-time-unit frequency hopping transmission scheme, or may include a first non-frequency hopping transmission scheme, a second non-frequency hopping transmission scheme, and an intra-time-unit frequency hopping transmission scheme, or may include a first non-frequency hopping transmission scheme, a second non-frequency hopping transmission scheme, an intra-time-unit frequency hopping transmission scheme, and an inter-time-unit frequency hopping transmission scheme, or may include at least a second non-frequency hopping transmission scheme and an intra-time-unit frequency hopping transmission scheme. For example, the plurality of transmission schemes may include a second non-frequency hopping transmission scheme and an intra-time-unit frequency hopping transmission scheme, and the plurality of transmission schemes may not include the first non-frequency hopping transmission scheme. It can be understood that the embodiments of this application provide two new PUCCH transmission schemes, namely, a first non-frequency hopping transmission scheme and an inter-time unit frequency hopping transmission scheme. The second non-frequency hopping transmission scheme and the intra-time unit frequency hopping transmission scheme can be considered as two existing PUCCH transmission schemes. To be compatible with the existing PUCCH transmission schemes, the first transmission scheme can be selected from the existing PUCCH transmission schemes and the new PUCCH transmission schemes provided in the embodiments of this application.

[0014] In a possible implementation, determining a first transmission scheme from the plurality of transmission schemes includes: determining a first transmission method from the plurality of transmission methods based on first indication information and / or a pre-specified rule, wherein the first indication information indicates the first transmission method;

[0015] This embodiment of the present application provides two methods for determining the first transmission scheme. For example, the first transmission scheme can be determined from multiple transmission schemes based on the first indication information. This is simple and straightforward. As another example, the first transmission scheme can be determined from multiple transmission schemes according to a pre-specified rule, and no signaling exchange is required. This reduces signaling overhead.

[0016] In a possible implementation, the first indication information is: Indicating at least one of a first non-frequency hopping transmission scheme, a second non-frequency hopping transmission scheme, an intra-time-unit frequency hopping transmission scheme, and an inter-time-unit frequency hopping transmission scheme.

[0017] The first indication information may occupy one or more bits to indicate a first transmission scheme from a plurality of transmission schemes. For example, the plurality of transmission schemes are two transmission schemes. The first indication information may occupy one bit, and different bit states indicate different transmission schemes. Of course, the first indication information may also occupy multiple bits. In addition to indicating the first transmission scheme, the first indication information may further indicate other information, such as a PUCCH resource block (RB) index. For example, for a second non-frequency hopping transmission scheme, there may be multiple schemes for determining a PUCCH RB index, and the first indication information may indicate that the first transmission scheme is the second non-frequency hopping transmission scheme and occupy multiple bits to indicate the PUCCH RB index. Since the first indication information may indicate both the first transmission scheme and the PUCCH RB index, signaling overhead can be reduced.

[0018] In a possible implementation, the first transmission scheme is a second non-frequency hopping transmission scheme, and the method further includes: the terminal device obtains, based on first indication information, a rule to be used for determining an RB position of the PUCCH, and the first indication information indicates a rule to be used from a plurality of rules.

[0019] For example, the plurality of rules includes at least two rules of a first rule, a second rule, and a third rule.

[0020] The first rule is that 0≦r PUCCH ≦(X / 2)-1, and the RB index value of PUCCH is

number

[0021] The second rule is that 0≦r PUCCH ≦X-1, and the RB index value of PUCCH is

number

[0022] The third rule is that 0≦r PUCCH ≦X-1, and the RB index value of PUCCH is

number

number

number

[0023] In a possible implementation, the method comprises: determining indices of orthogonal sequences having lengths Li and Lj, where i=1, 2, 3, 4, 5, or 6 and j=1, 2, 3, 4, 5, or 6, and if i=j, determining an index of the orthogonal sequence having length Li and an index of the orthogonal sequence having length Lj based on the first index indication information; If i≠j, the method further includes determining an index of the orthogonal sequence having a length Li based on the second index indication information, and determining an index of the orthogonal sequence having a length Lj based on the third index indication information.

[0024] It should be understood that the indices of two orthogonal sequences having the same length may be the same. Therefore, the index of one orthogonal sequence can be determined to determine the index of the other orthogonal sequence. In this case, one index indication information can be used to indicate the indices of two orthogonal sequences having the same length, and no further index indication information is required. This reduces signaling exchange. The indices of two orthogonal sequences having different lengths may be the same or different. Therefore, for two orthogonal sequences having different lengths, corresponding indices can be indicated by using two index indication information, respectively.

[0025] In a possible implementation, the method further includes sending first capability information to the network device, wherein the first capability information indicates at least one of the following: whether a first non-frequency-hopping transmission scheme is supported, whether an inter-time-unit frequency-hopping transmission scheme is supported, whether the terminal device determines RB indices of the PUCCH according to a second rule, and whether the terminal device determines RB indices of the PUCCH according to a third rule.

[0026] Based on the capability information reported by the terminal device, the network device may instruct the rules used to determine the PUCCH transmission scheme and the RB index of the PUCCH to be used by the terminal device to ensure that the PUCCH transmission scheme configured or instructed to the terminal device matches the actual capabilities of the terminal device.

The second communication device can be a communication device or a communication apparatus, for example, a chip or a chip system, that can support the communication device in realizing the functions required in the method.

[0113] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0114] The technical solutions provided in the embodiments of this application may be applied to the fifth generation (5G) mobile communication system, for example, an NR system, or may be applied to a long term evolution (LTE) system, or may be applied to a next generation mobile communication system or another similar communication system, which is not specifically limited.

[0115] Please refer to FIG. 1. FIG. 1 is an exemplary diagram depicting the architecture of a communication system to which embodiments of this application are applicable. The communication system may include a core network device, a network device, and at least one terminal. In FIG. 1, two terminals are used as an example. The terminal device is connected to the network device wirelessly, and the network device is connected to the core network device wirelessly or by wire. The core network device and the network device may be different physical devices independent of each other, or the functions of the core network device and the logical functions of the network device may be integrated into the same physical device, or some functions of the core network device and some functions of the network device may be integrated into the same physical device. It should be noted that FIG. 1 is merely an example. The numbers of core network devices, network devices, and terminals included in the mobile communication system are not limited in embodiments of this application. In some embodiments, the communication system may further include another network device, for example, a wireless relay device or a wireless backhaul device.

[0116] A network device is an access device through which a terminal wirelessly accesses a mobile communication system. For example, the network device includes an access network (AN) device or a base station (e.g., an access point). The network device may also be a device that communicates with a terminal over an air interface. In one example, the network device is another possible terminal device, or in another example, a road side unit (RSU) in V2X technology. The base station may be configured to convert received radio frames to and from Internet Protocol (IP) packets and serve as a router between the terminal and the rest of the access network, which may include an IP network. The RSU may be a fixed infrastructure entity supporting V2X applications or may exchange messages with another entity supporting V2X applications. The network device may further coordinate attribute management of the air interface. For example, the network device may include an evolved base station (NodeB, eNB, or e-NodeB, evolutionary Node B) in a long term evolution (LTE) system or a long term evolution-advanced (LTE-A) system, or a next generation node B (gNB) in a 5G NR system, or a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (Cloud RAN) system, or an access node in a wireless-fidelity (WiFi) system.In the embodiments of this application, the specific technology used by the wireless network device and the specific device type are not limited.

[0117] The terminal device in the embodiments of this application may be a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile console, a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device in the embodiments of this application may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver functionality, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, or the like. The network device may be a next generation node B (gNB) in an NR system, an evolutional node B (eNB) in an LTE system, or the like.

[0118] Terminals may be classified into multiple types based on the service types supported by the terminal. For example, a REDCAP UE is a reduced-capability or low-capability terminal. This type of terminal has lower complexity than another type of terminal in terms of bandwidth, power consumption, and number of antennas, for example, narrower bandwidth, lower power consumption, and fewer antennas. This type of terminal may also be referred to as an NR light (NRL) terminal, i.e., a light terminal. Relatively, a non-reduced-capability or non-low-capability terminal device (e.g., an eMBB terminal device) may be referred to as a normal terminal device or a legacy terminal device in embodiments of this application. Alternatively, in embodiments of this application, there may be two types of terminal devices. For example, a first-type terminal device is a reduced-capability terminal device. A second-type terminal device may be a terminal device other than a reduced-capability terminal device.

[0119] The terminal device in the embodiment of this application may be a first-type terminal device, a second-type terminal device, or another terminal device that requires improved transmission performance, such as an NR Enhanced Mobile Broadband (eMBB) terminal device. The differences between the first-type terminal device and the second-type terminal device include at least one of the following:

[0120] 1. Different bandwidth capabilities. The maximum bandwidth supported by the first type terminal device may be greater than the maximum bandwidth supported by the second type terminal device. For example, the first type terminal device may support up to 100 MHz of frequency domain resources in one carrier for communicating with the network device, and the second type terminal device may support up to 20 MHz, 10 MHz, or 5 MHz of frequency domain resources in one carrier for communicating with the network device.

[0121] 2. The number of transceiver antennas is different. The antenna configuration of the first type terminal device may be larger than the antenna configuration of the second type terminal device. For example, the minimum antenna configuration supported by the first type terminal device may be larger than the maximum antenna configuration supported by the second type terminal device.

[0122] 3. The maximum uplink transmission power is different: The maximum uplink transmission power of the first type terminal device may be greater than the maximum uplink transmission power of the second type terminal device.

[0123] 4. The first type terminal device and the second type terminal device correspond to different protocol versions. For example, NR Rel-15 and NR Rel-16 terminal devices may be considered first type terminal devices, and the second type terminal devices may be considered NR Rel-17 terminal devices.

[0124] 5. The first type terminal device and the second type terminal device support different carrier aggregation (CA) capabilities. For example, the first type terminal device may support carrier aggregation, but the second type terminal device does not support carrier aggregation. In another example, both the second type terminal device and the first type terminal device support carrier aggregation, but the maximum number of carriers that can be simultaneously aggregated by the first type terminal device is greater than the maximum number of carriers that can be simultaneously aggregated by the second type terminal device.

[0125] 6. The frequency division duplex (FDD) capabilities of the first type terminal device and the second type terminal device are different. For example, the first type terminal device may support full-duplex FDD, and the second type terminal device may only support half-duplex FDD.

[0126] 7. The second-type terminal device and the first-type terminal device have different data processing time capabilities. For example, the minimum delay between receiving downlink data by the first-type terminal device and sending feedback for the downlink data is smaller than the minimum delay between receiving downlink data by the second-type terminal device and sending feedback for the downlink data.

[0127] 8. The first type terminal device and the second type terminal device correspond to different uplink and / or downlink peak transmission rates.

[0128] The following describes technical terms in the embodiments of this application.

[0129] (1) Frequency Retuning. When a network device communicates with a terminal device, the radio frequency components in the network device and the terminal device operate within a specific frequency range. The center frequency at which the radio frequency device operates may determine the frequency resource location at which the network device and the terminal device operate. If the frequency range at which the radio frequency device operates changes, for example, if the frequency domain location and / or bandwidth changes, the radio frequency device needs to perform frequency retuning to change the center frequency and frequency resource location for transmission / reception. The frequency retuning needs to occupy an adjustment duration, and the network device and the terminal device cannot receive or transmit information within the adjustment duration.

[0130] (2) Time unit. The time unit may be a slot or a subframe, or may include one or more symbols. In the embodiments of this application, an example in which the time unit is a slot is used. A portion of a slot may be a symbol used for uplink transmission within the slot, for example, a symbol starting from an uplink / downlink switching point to a slot boundary, or a symbol used for uplink transmission starting from an uplink / downlink switching point to a next uplink / downlink switching point. For downlink transmission, a portion of a slot may be a symbol used for downlink transmission starting from a slot boundary to an uplink / downlink switching point, a symbol used for downlink transmission starting from an uplink / downlink switching point to a slot boundary, or a symbol used for downlink transmission starting from an uplink / downlink switching point to a next uplink / downlink switching point. In this application, unless otherwise specified, a symbol is a time-domain symbol. The time-domain symbols here may be orthogonal frequency division multiplexing (OFDM) symbols or Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) symbols.

[0131] (3) Frequency hopping: Frequency hopping is a communication method in which the frequency domain resources used in the information transmission process are changed according to a rule to obtain frequency diversity gain. Figure 2 is a schematic diagram of a frequency hopping signal. As shown in Figure 2, five time periods t1 to t5 are included in the time domain, and five frequency domain resources f1 to f5 are included in the frequency domain. The five time periods t1 to t5 correspond to frequency domain resources f3, f1, f5, f2, and f4, respectively.

[0132] In an NR system, inter-slot frequency hopping is supported in the case of PUCCH repetition, and intra-slot frequency hopping is supported in the case of PUCCH non-repetition. Whether intra-slot frequency hopping or inter-slot frequency hopping is used is indicated by using radio resource control (RRC) signaling, and scheduling signaling (e.g., DCI) is used to indicate whether frequency hopping is used in data transmission. In addition, the scheduling signaling further indicates the time-frequency resources for data transmission.

[0133] Inter-slot frequency hopping means that the frequency domain resources used for information transmission remain unchanged within a slot, but change between different slots according to a predetermined rule. Figure 3 is a schematic diagram of inter-slot frequency hopping when the PUCCH is transmitted twice repeatedly. As shown in Figure 3, two slots are included in the time domain, each having 14 symbols, and two frequency domain resources f1 and f2 are included in the frequency domain. The transmitting end transmits data in the first slot by using frequency domain resource f1 and transmits data in the second slot by using frequency domain resource f2. It should be noted that when the OFDM symbol uses a normal cyclic prefix (NCP), one slot may include 14 symbols. When the OFDM symbol uses an extended cyclic prefix (ECP), one slot may include 12 symbols. In the embodiment of this application, an example in which one slot includes 14 symbols is used.

[0134] Intra-slot frequency hopping means that the frequency domain resources used for information transmission change within a slot according to a predetermined rule. For example, two-hop frequency hopping is performed within a slot. Information to be transmitted is divided into two parts, and the two parts are transmitted by using different frequency domain resources within the slot. FIG. 4 is a schematic diagram of intra-slot frequency hopping. As shown in FIG. 4, one slot is included in the time domain, and two frequency domain resources f1 and f2 are included in the frequency domain. Information transmitted by a transmitting end includes two parts, namely, a first information portion and a second information portion. The transmitting end transmits the first information portion from symbol 6 to symbol 9 by using frequency domain resource f2, and transmits the second information portion from symbol 10 to symbol 13 by using frequency domain resource f1. The shaded areas in FIGS. 3 and 4 indicate resources occupied for information transmission. In the embodiment of this application, information transmission may be signaling transmission, data transmission, or reference signal transmission.

[0135] (4) Carrier Bandwidth Part: A carrier bandwidth part may be a segment of continuous resources in the frequency domain, and may also be referred to as a bandwidth part (BWP or BP), a subband, a subband bandwidth, a narrowband, a narrowband bandwidth, or may have another name. In the embodiment of this application, the name of the carrier bandwidth part is not limited. For simplicity, this specification uses an example in which the name is BWP.

[0136] The carrier bandwidth portion described in this specification may be a downlink carrier bandwidth portion and used by a terminal device for downlink reception. In this case, the bandwidth of the carrier bandwidth portion may exceed the reception bandwidth capability of the terminal device. Alternatively, the carrier bandwidth portion may be an uplink carrier bandwidth portion and used by a terminal device for uplink transmission. In this case, the bandwidth of the carrier bandwidth portion may exceed the transmission bandwidth capability of the terminal device. In an embodiment of this application, the bandwidth capability of the terminal device may be a channel bandwidth supported by the terminal device, a maximum channel bandwidth supported by the terminal device, the number of resource blocks (RBs) supported by the terminal device, or the maximum number of resource blocks supported by the terminal device.

[0137] The above describes the network architecture to which the embodiments of this application are applicable and related terms. The following describes the technical features related to the technical solutions provided in the embodiments of this application.

[0138] The PUCCH is mainly used to carry UCI and DMRS. For example, the length of the PUCCH is assumed to be L symbols. L5 symbols of the L symbols are used to transmit UCI on the PUCCH, and L6 symbols of the L symbols are used to transmit DMRS on the PUCCH. It should be understood that L5 + L6 = L, where L5, L6, and L are all positive integers. UCI on the PUCCH can be transmitted using intra-slot frequency hopping or without intra-slot frequency hopping. When UCI on the PUCCH is transmitted using intra-slot frequency hopping, UCI transmission on L5 symbols is divided into two hops. When the PUCCH is transmitted without intra-slot frequency hopping, UCI is transmitted on L5 symbols without frequency hopping. Similarly, DMRS on the PUCCH can be transmitted using intra-slot frequency hopping or without intra-slot frequency hopping. When DMRS on PUCCH is transmitted using intra-slot frequency hopping, the DMRS transmission over L6 symbols is split into two hops. When DMRS on PUCCH is transmitted without intra-slot frequency hopping, the DMRS is transmitted over L6 symbols without frequency hopping.

[0139] Current PUCCH transmission without intra-slot frequency hopping means that UCI on the PUCCH is transmitted without frequency hopping by using L5 symbols in the slot, and DMRS on the PUCCH is transmitted without frequency hopping by using L6 symbols in the slot. It should be understood that to improve resource utilization, the PUCCH may be transmitted in an orthogonal sequence block spreading manner, i.e., to support PUCCH transmission for more terminal devices, the PUCCH channel is shared on the same resource (e.g., resource block). Thus, when the PUCCH is transmitted without intra-slot frequency hopping, L5 symbols are transmitted using an orthogonal sequence with a length of L5, and L6 symbols are transmitted using an orthogonal sequence with a length of L6. L5 and L6 may be the same or different. When L5 = L6, the index of the orthogonal sequence with a length of L5 may be the same as or different from the index of the orthogonal sequence with a length of L6.

[0140] It should be noted that this embodiment of this application further provides a new scheme of PUCCH transmission without intra-slot frequency hopping. For distinction, the new scheme of PUCCH transmission without intra-slot frequency hopping provided in this embodiment of this application is hereinafter referred to as a first non-frequency hopping transmission scheme, and the current scheme of PUCCH transmission without intra-slot frequency hopping is hereinafter referred to as a second non-frequency hopping transmission scheme.

[0141] PUCCH transmission using intra-slot frequency hopping means that UCI transmission of PUCCH over L5 symbols in a slot is split into two hops, and DMRS transmission of PUCCH over L6 symbols in a slot is split into two hops. For example, L51 symbols of the L5 symbols are used for first-hop transmission, and L52 symbols of the L5 symbols are used for second-hop transmission. The resource blocks used by UCI in the first hop are different from the resource blocks used by UCI in the second hop. Similarly, L61 symbols of the L6 symbols are used for first-hop transmission, and L62 symbols of the L6 symbols are used for second-hop transmission. The resource blocks used by DMRS in the first hop are different from the resource blocks used by DMRS in the second hop.

[0142] See Figure 5 for an example. Figure 5 is a schematic diagram of PUCCH transmission using intra-slot frequency hopping. In Figure 5, an example of intra-slot frequency hopping with two hops for an eMBB terminal device is used. In Figure 5, an example is used in which the time domain resource is one slot, i.e., 14 symbols. Each shaded area in Figure 5 corresponds to one symbol. As shown in Figure 5, the UCI and DMRS on the PUCCH in one slot are separately divided into two parts. The first part uses a first frequency domain resource in the slot, and the second part uses a second frequency domain resource in the slot.

[0143] For ease of understanding, please refer to Table 1. Table 1 is a summary table of PUCCH length and UCI transmission on PUCCH. As shown in the first column of Table 1, the length of PUCCH can be 4 to 14 symbols. If UCI on PUCCH is transmitted without frequency hopping, L5 symbols are used to transmit UCI. If UCI on PUCCH is transmitted using intra-slot frequency hopping, UCI transmission on L5 symbols is divided into two hops. In Table 1, the number of symbols (L51) shown in the third column is used for the first hop, and the number of symbols (L52) shown in the fourth column is used for the second hop. L5 = L51 + L52.

[0144] [Table 1]

[0145] Please refer to Table 2. Table 2 is a summary table of PUCCH length and DMRS transmission on PUCCH. As shown in the first column of Table 2, the length of PUCCH can be 4 to 14 symbols. If DMRS on PUCCH is transmitted without frequency hopping, L6 symbols are used to transmit DMRS. If DMRS on PUCCH is transmitted using intra-slot frequency hopping, DMRS transmission on L6 symbols is split into two hops. For example, in Table 2, L61 symbols (number shown in the third column) are used for the first hop, and L62 symbols (number shown in the fourth column) are used for the second hop. L6 = L61 + L62.

[0146] [Table 2]

[0147] In order to improve resource utilization, the PUCCH may be transmitted in an orthogonal sequence block spreading manner, that is, the PUCCH channel is shared on the same resource (e.g., resource block) to support PUCCH transmission of more terminal devices. For ease of understanding, please refer to Figure 6. Figure 6 is a schematic diagram of PUCCH transmission by two terminal devices in an orthogonal sequence block spreading manner. In Figure 6, each shaded area corresponds to one symbol.

[0148] It is assumed that the cyclic prefix of the symbols included in the slots shown in FIG. 6 is a normal cyclic prefix, and one slot includes 14 symbols. The PUCCH of terminal device 1 and the PUCCH of terminal device 2 both occupy 14 symbols, and terminal device 1 and terminal device 2 share the same resource block. In this case, orthogonal sequence 1 may be used for PUCCH transmission of terminal device 1, and orthogonal sequence 2 may be used for PUCCH transmission of terminal device 2. The PUCCHs of terminal device 1 and terminal device 2 are transmitted using frequency hopping within the slot. For example, seven symbols in the slot are used to transmit UCI on the PUCCH, and the other seven symbols in the slot are used to transmit DMRS on the PUCCH.

[0149] It should be understood that for PUCCH transmission using intra-slot frequency hopping, to improve resource utilization, the PUCCH may also be transmitted in an orthogonal sequence block spreading manner. That is, the first and second hops of the UCI carried on the PUCCH may also be transmitted in an orthogonal sequence block spreading manner. For example, the first hop of the UCI is transmitted by using an orthogonal sequence having a length of L51, and the second hop of the UCI is transmitted by using an orthogonal sequence having a length of L52. For specific values ​​of L51 and L52, see Table 1. Similarly, for DMRS, the first and second hops of the DMRS carried on the PUCCH may also be transmitted in an orthogonal sequence block spreading manner. For example, the first hop of the DMRS is transmitted by using an orthogonal sequence having a length of L61, and the second hop of the DMRS is transmitted by using an orthogonal sequence having a length of L62. For specific values ​​of L61 and L62, see Table 2.

[0150] In addition, the resource blocks used by the UCI in the first hop are different from the resource blocks used by the UCI in the second hop. The length of the orthogonal sequence used by the UCI in the first hop may be the same as or different from the length of the orthogonal sequence used by the UCI in the second hop. That is, the index of the orthogonal sequence used by the UCI in the first hop may be the same as or different from the index of the orthogonal sequence used by the UCI in the second hop. Similarly, the resource blocks used by the DMRS in the first hop are different from the resource blocks used by the DMRS in the second hop. The length of the orthogonal sequence used by the DMRS in the first hop may be the same as or different from the length of the orthogonal sequence used by the DMRS in the second hop. That is, the index of the orthogonal sequence used by the DMRS in the first hop may be the same as or different from the index of the orthogonal sequence used by the UCI in the second hop.

[0151] The resource blocks used by the UCI in the first hop may be the same as the resource blocks used by the DMRS in the first hop, and the resource blocks used by the UCI in the second hop may be the same as the resource blocks used by the DMRS in the second hop. The length of the orthogonal sequence used by the UCI in the first hop may be the same as the length of the orthogonal sequence used by the DMRS in the first hop. For example, the index of the orthogonal sequence used by the UCI in the first hop may be the same as or different from the index of the orthogonal sequence used by the DMRS in the first hop. The length of the orthogonal sequence used by the UCI in the second hop may be the same as the length of the orthogonal sequence used by the DMRS in the second hop. For example, the index of the orthogonal sequence used by the UCI in the second hop may be the same as or different from the index of the orthogonal sequence used by the DMRS in the second hop.

[0152] A terminal device may transmit a PUCCH by using either of the two PUCCH transmission schemes described above. Typically, a terminal device receives or transmits a PUCCH within a frequency range that does not exceed the maximum channel bandwidth capability of the terminal device. In this case, as shown in FIG. 7, the terminal device does not need to perform frequency readjustment. In FIG. 7, the frequency domain resources occupied for PUCCH transmission or reception are shaded. The terminal device may need to receive or transmit a PUCCH within a larger frequency range. However, for a reduced-capability terminal device, the bandwidth capability of the reduced-capability terminal device is limited. If the reduced-capability terminal device receives or transmits information within a frequency range that exceeds the maximum channel bandwidth capability of the terminal device, the reduced-capability terminal device needs to perform frequency readjustment to receive or transmit information within the larger frequency range. As shown in FIG. 8, when a reduced-capability terminal device transmits a PUCCH within a frequency range that exceeds the maximum channel bandwidth capability of the reduced-capability terminal device, the reduced-capability terminal device requires a duration of M symbols for frequency readjustment. Since M symbols are used for frequency readjustment, the PUCCH cannot be transmitted within the adjustment duration of M symbols, causing degraded PUCCH transmission performance for reduced capability terminal devices.

[0153] When a reduced-capability terminal device performs frequency readjustment within the duration of M symbols, it may also be understood that M symbols are punctured and cannot be used to transmit a PUCCH, while a normal terminal device can transmit a PUCCH using M symbols. Therefore, interference caused by a reduced-capability terminal device to a normal terminal device cannot be avoided. For example, there are originally L symbols for transmitting UCI or DMRS on the PUCCH of a reduced-capability terminal device or a normal terminal device. For a reduced-capability terminal device, M symbols out of the L symbols are used for frequency readjustment, i.e., M symbols are punctured. In this case, the length of the orthogonal sequence used by a reduced-capability terminal device to transmit UCI or DMRS on the PUCCH changes from L to LM. However, for a normal terminal device, the length of the orthogonal sequence used to transmit UCI or DMRS on the PUCCH is still L. It is clear that orthogonality between the PUCCH transmission of the reduced-capability terminal device and the PUCCH transmission of the normal terminal device cannot be guaranteed, and interference will be caused to the PUCCH transmission of the normal terminal device, resulting in degraded PUCCH transmission performance of the normal terminal device.

[0154] In consideration of this, this embodiment of this application provides two new PUCCH transmission schemes.Even if a reduced-capability terminal device receives or transmits a PUCCH within a frequency range that exceeds the maximum channel bandwidth capability of the reduced-capability terminal device, the interference caused by the reduced-capability terminal device to the PUCCH transmission and reception of a normal terminal device can be reduced, and the degraded PUCCH transmission performance of the normal terminal device can be avoided as much as possible.In this way, the degraded PUCCH transmission performance of the reduced-capability terminal device can be avoided.

[0155] The first new PUCCH transmission scheme provided in this embodiment of the present application is an inter-time unit frequency hopping scheme. Specifically, the first hop of the PUCCH is transmitted by using F symbols within the nth time unit, and the second hop of the PUCCH is transmitted by using LF symbols within the (n+1)th time unit. The length of the PUCCH is L symbols, and there is an interval of 14-F symbols between the last symbol of the F symbols and the first symbol of the LF symbols, where F and L are positive integers. It should be understood that when the time unit is 1 slot, one slot includes 14 symbols. Alternatively, for 15 kHz, one subframe is equivalent to one slot. This embodiment of the present application specifies that there is an interval of a specific number of symbols between the first and second hops of the PUCCH. Therefore, for a reduced-capability terminal device, even if the PUCCH is received or transmitted within a frequency range that exceeds the maximum channel bandwidth capability of the reduced-capability terminal device, frequency readjustment may be performed at a specific number of symbols, and PUCCH transmission will not be affected. In this way, degraded PUCCH transmission performance of reduced capability terminal devices can be avoided.

[0156] In addition, in this embodiment of this application, the interval between the last symbol of the first hop for transmitting PUCCH and the first symbol of the second hop for transmitting PUCCH is 14 minus the length of the first hop, which can ensure that the starting symbol of the first hop is the same as the starting symbol of the second hop, so that the PUCCH is transmitted from the starting position closest to the designated PUCCH resource.

[0157] For ease of understanding, please refer to Figure 9. Figure 9 is a schematic diagram of PUCCH transmission using frequency hopping between time units according to an embodiment of this application. Figure 9 uses an example in which the time unit is a slot. It can be seen from Figure 9 that the first hop of PUCCH is transmitted in the nth slot, and the second hop of PUCCH is transmitted in the (n+1)th slot. There is an interval of X symbols between the last symbol used for the first hop of PUCCH transmission and the first symbol used for the second hop of PUCCH transmission, where X is related to the length F of the first hop, for example, X = 14 - F. That is, the number of symbols between the last symbol used for the first hop of PUCCH transmission and the first symbol used for the second hop of PUCCH transmission is less than 14. For example, it is assumed that the length of PUCCH is L symbols, and F symbols in the nth slot are used for the first hop of PUCCH transmission. In this case, in the (n+1)th slot, L symbols are used for the second hop of PUCCH transmission, and X = 14 - floor(L / 2). In particular, when L is an even number, X = 14 - (L / 2). For example, when L = 14, a schematic diagram of PUCCH transmission using inter-time unit frequency hopping corresponding to FIG. 9 is shown in FIG. 10. From FIG. 9 and FIG. 10, it can be seen that there is an interval of X symbols between the first and second hops of PUCCH. In this case, when transmitting or receiving PUCCH in a frequency range that exceeds the maximum channel bandwidth capability of the reduced-capability terminal device, the reduced-capability terminal device may perform frequency readjustment at X symbols and not occupy symbols for PUCCH transmission of the reduced-capability terminal device. This avoids degraded PUCCH transmission performance of the reduced-capability terminal device.

[0158] According to a second new PUCCH transmission scheme (i.e., a first non-frequency hopping transmission scheme in this application) provided in this embodiment of this application, the PUCCH is transmitted without frequency hopping within a time unit, and the UCI transmission of the PUCCH within the time unit includes a first part and a second part, where the first part is transmitted by using an orthogonal sequence having a length of L1, and the second part is transmitted by using an orthogonal sequence having a length of L2. Similarly, according to a second PUCCH transmission scheme provided in this embodiment of this application, the PUCCH may also be transmitted without frequency hopping within a time unit, and the DMRS on the PUCCH in the time unit includes a third part and a fourth part, where the third part is transmitted by using an orthogonal sequence having a length of L3, and the fourth part is transmitted by using an orthogonal sequence having a length of L4. Alternatively, according to a second PUCCH transmission scheme provided in this embodiment of this application, the PUCCH is transmitted without frequency hopping within the time unit, the UCI transmission of the PUCCH within the time unit includes a first part and a second part, where the first part is transmitted by using an orthogonal sequence having a length of L1 and the second part is transmitted by using an orthogonal sequence having a length of L2, and the DMRS on the PUCCH within the time unit includes a third part and a fourth part, where the third part is transmitted by using an orthogonal sequence having a length of L3 and the fourth part is transmitted by using an orthogonal sequence having a length of L4.

[0159] According to the first non-frequency hopping transmission scheme provided in this embodiment of the present application, the UCI on the PUCCH is essentially divided into two parts, and the two parts are respectively transmitted by using orthogonal sequences of the same length or different lengths. Similarly, the DMRS on the PUCCH may also be divided into two parts, and the two parts are respectively transmitted by using orthogonal sequences of the same length or different lengths.

[0160] For example, L5 symbols in one slot are used to transmit UCI on the PUCCH, and L6 symbols in that slot are used to transmit DMRS. The UCI on the L5 symbols is divided into two parts. For example, L1 symbols of the L5 symbols are used to transmit the first part of the UCI, and L2 symbols of the L5 symbols are used to transmit the second part of the UCI. The first part is transmitted using an orthogonal sequence of length L1, and the second part is transmitted using an orthogonal sequence of length L2, where L1 + L2 = L5. Similarly, L3 symbols of the L6 symbols are used to transmit the third part of the DMRS, and L4 symbols of the L6 symbols are used to transmit the fourth part of the DMRS. The third part is transmitted using an orthogonal sequence of length L3, and the fourth part is transmitted using an orthogonal sequence of length L4. It should be understood that L3 + L4 = L6.

[0161] In this embodiment of the application, the relationship between the PUCCH length L and L1 and L2 may be pre-specified. L1 and L2 may be determined based on the relationship and the PUCCH length L. See Table 3 for an example. Table 3 is a table of the relationship between the PUCCH length L and L1 and L2 according to this embodiment of the application.

[0162] [Table 3]

[0163] The first part of the UCI is transmitted by using an orthogonal sequence having a length of L1, and the second part of the UCI is transmitted by using an orthogonal sequence having a length of L2. There are multiple orthogonal sequences having a length of L1, and also multiple orthogonal sequences having a length of L2. When transmitting the PUCCH, the terminal device is required to determine an orthogonal sequence for transmitting the first part of the UCI from the multiple orthogonal sequences having a length of L1, and to determine an orthogonal sequence for transmitting the second part of the UCI from the multiple orthogonal sequences having a length of L2. It should be understood that for a sequence having a length of Li, the network device indicates an orthogonal sequence having a length of Li from the Li orthogonal sequences. Correspondingly, the terminal device may determine an orthogonal sequence having a length of Li. Thus, the terminal device may determine an orthogonal sequence for transmitting the first part of the UCI from the L1 orthogonal sequences having a length of L1, and may determine an orthogonal sequence for transmitting the second part of the UCI from the L2 orthogonal sequences having a length of L2.

[0164] In this embodiment of the present application, if the lengths of the orthogonal sequences are different, the indices of the orthogonal sequences are different. If the lengths of the orthogonal sequences are the same, the indices of the orthogonal sequences may be the same or different. The correspondence between the indices of the orthogonal sequences with length L1 and the indices of the orthogonal sequences with length L2 may be specified or negotiated, for example, the indices may be the same or different, so that the indices of the orthogonal sequences of all lengths are determined based on the correspondence.

[0165] For example, it is pre-specified that the index of an orthogonal sequence having a length of L1 is the same as the index of an orthogonal sequence having a length of L2. In this case, the terminal device only needs to determine the index of the orthogonal sequence having a length of L1 to determine the index of the orthogonal sequence having a length of L2. Alternatively, the terminal device only needs to determine the index of the orthogonal sequence having a length of L2 to determine the index of the orthogonal sequence having a length of L1.

[0166] For example, the index of the orthogonal sequence having a length of L1 is pre-specified to be different from the index of the orthogonal sequence having a length of L2, in which case the terminal device needs to separately determine the index of the orthogonal sequence having a length of L1 and the index of the orthogonal sequence having a length of L2.

[0167] How the terminal device determines the index of the orthogonal sequence for transmitting UCI will be described in detail below with reference to the related content regarding determining the transmission scheme to be used for transmitting PUCCH by the terminal device.

[0168] The above describes UCI transmission in the first non-frequency hopping transmission scheme. DMRS transmission is similar to UCI transmission. That is, the relationship between the PUCCH length L and L3 and L4 may be pre-specified. L3 and L4 may be determined based on the relationship and the PUCCH length L. See Table 4 for an example. Table 4 is a table of the relationship between the PUCCH length L and L3 and L4 according to this embodiment of the present application.

[0169] [Table 4]

[0170] The third portion of the DMRS is transmitted using an orthogonal sequence having a length of L3, and the fourth portion of the DMRS is transmitted using an orthogonal sequence having a length of L4. There are multiple orthogonal sequences having a length of L3, and there are also multiple orthogonal sequences having a length of L4. When transmitting the PUCCH, the terminal device is required to determine an orthogonal sequence for transmitting the third portion of the DMRS from the multiple orthogonal sequences having a length of L3, and to determine an orthogonal sequence for transmitting the fourth portion of the DMRS from the multiple orthogonal sequences having a length of L4. It should be understood that for a sequence having a length of L, the network device indicates an orthogonal sequence having a length of L from the L orthogonal sequences. Correspondingly, the terminal device may determine an orthogonal sequence having a length of L. Thus, the terminal device may determine an orthogonal sequence for transmitting the third portion of the DMRS from the L3 orthogonal sequences having a length of L3, and may determine an orthogonal sequence for transmitting the fourth portion of the DMRS from the L4 orthogonal sequences having a length of L4.

[0171] Similar to the UCI, the correspondence between the index of the orthogonal sequence of length L3 and the index of the orthogonal sequence of length L4 may be specified or negotiated, e.g., the indexes are the same or different, so that the indexes of the orthogonal sequences of all lengths are determined based on the correspondence.

[0172] For example, it is pre-specified that the index of an orthogonal sequence having a length of L3 is the same as the index of an orthogonal sequence having a length of L4. In this case, the terminal device only needs to determine the index of the orthogonal sequence having a length of L3 to determine the index of the orthogonal sequence having a length of L4. Alternatively, the terminal device only needs to determine the index of the orthogonal sequence having a length of L4 to determine the index of the orthogonal sequence having a length of L3.

[0173] For example, the index of the orthogonal sequence having a length of L3 is pre-specified to be different from the index of the orthogonal sequence having a length of L4, in which case the terminal device needs to separately determine the index of the orthogonal sequence having a length of L3 and the index of the orthogonal sequence having a length of L4.

[0174] How a terminal device determines the index of an orthogonal sequence for transmitting a DMRS will be described in detail below with reference to the related content regarding determining the transmission scheme to be used for transmitting a PUCCH by a terminal device.

[0175] The reduced-capability terminal device uses the first non-frequency hopping transmission scheme provided in this embodiment of this application, so that the degraded PUCCH transmission performance of the reduced-capability terminal device caused by frequency readjustment can be avoided.In addition, when the reduced-capability terminal device and the normal terminal device share the PUCCH resource, the reduced-capability terminal device uses the first non-frequency hopping transmission scheme provided in this embodiment of this application, so that the sequences used when the normal terminal device and the reduced-capability terminal device transmit PUCCH are still orthogonal.This avoids interference with the PUCCH transmission of the normal device and ensures the PUCCH transmission performance of the normal terminal device.

[0176] For ease of understanding, please refer to FIG. 11. FIG. 11 illustrates a reduced-capability terminal device and a normal terminal device sharing a PUCCH resource to transmit a PUCCH. FIG. 11 uses an example in which two normal terminal devices and one reduced-capability terminal device transmit UCI of a PUCCH. Normal terminal device 1 and normal terminal device 2 transmit the PUCCH using intra-slot frequency hopping, and the reduced-capability terminal device transmits the PUCCH using a first non-frequency hopping transmission method. It is assumed that the orthogonal sequence is generated by using a formula for constructing an orthogonal sequence in PUCCH format 1 in the existing NR standard. It can be seen from FIG. 11 that normal terminal device 1 transmits the first hop of UCI carried on the PUCCH by using an orthogonal sequence having a length of 3, i.e., [0, 1, 2], and transmits the second hop of UCI carried on the PUCCH by using an orthogonal sequence having a length of 4, i.e., [0, 0, 2, 2]. The normal terminal device 2 transmits the first hop of the UCI carried on the PUCCH by using an orthogonal sequence having a length of 3, i.e., [0, 2, 1], and transmits the second hop of the UCI carried on the PUCCH by using an orthogonal sequence having a length of 4, i.e., [0, 0, 2, 2]. This can ensure orthogonality between the PUCCH transmission of the normal terminal device 1 and the PUCCH transmission of the normal terminal device 2. The reduced-capability terminal device transmits the first part of the UCI on the PUCCH by using an orthogonal sequence having a length of 3, for example, [0, 1, 2], and transmits the second part of the UCI by using an orthogonal sequence having a length of 4, for example, [0, 2, 0, 2]. In order to avoid interference with the PUCCH transmission of the normal device and ensure the PUCCH transmission performance of the normal terminal device, it can be known that orthogonality can be guaranteed between the PUCCH transmission of the reduced-capability terminal device and the PUCCH transmissions of the normal terminal device 1 and normal terminal device 2.

[0177] The above describes two PUCCH transmission schemes newly introduced in this embodiment of this application. In addition to the existing PUCCH transmission schemes, namely, the intra-slot frequency hopping transmission scheme and the second non-frequency hopping transmission scheme, there are a total of four PUCCH transmission schemes.

[0178] With reference to the above-mentioned embodiments and the related accompanying drawings, the following describes which of the four PUCCH transmission schemes is used by a terminal device for PUCCH transmission or reception. For example, the terminal device may determine the transmission scheme, or the network device may instruct the terminal device to use the transmission scheme.

[0179] Please refer to FIG. 12 below. FIG. 12 illustrates a PUCCH transmission method according to an embodiment of this application. The following description process uses an example in which this method is applied to the network architecture illustrated in FIG. 1. In addition, this method can be performed by two communication devices. The two communication devices are, for example, a first communication device and a second communication device. The first communication device may be a network device or a communication device capable of supporting the network device in implementing the functions required in this method. Alternatively, the first communication device may be a terminal device or a communication device capable of supporting the terminal device in implementing the functions required in this method. Of course, the first communication device may alternatively be another communication device, for example, a chip system. Similarly, the second communication device may be a network device or a communication device capable of supporting the network device in implementing the functions required in this method. Alternatively, the second communication device may be a terminal device or a communication device capable of supporting the terminal device in implementing the functions required in this method. Of course, the second communication device may alternatively be another communication device, for example, a chip system. In addition, the implementation of the first communication device and the second communication device is not limited. For example, the first communication device may be a network device, and the second communication device is a terminal device. Alternatively, both the first communication device and the second communication device are network devices. Alternatively, both the first communication device and the second communication device are terminal devices. Alternatively, the first communication device is a network device, and the second communication device is a communication device that can support the terminal device in implementing the functions required in the method. The network device is, for example, a base station.

[0180] For ease of explanation, the following uses an example in which this method is performed by a network device and a terminal device. In other words, an example in which the first communication device is a network device and the second communication device is a terminal device is used. If this embodiment is applied to the network architecture shown in FIG. 1, the network device described below may be the network device in the network architecture shown in FIG. 1. It should be noted that this embodiment of this application is described by simply using a network device and a terminal device as an example and is not limited to two communication devices. For example, the embodiment of this application may also be performed by a terminal device and a terminal device, i.e., both communication ends are terminal devices.

[0181] S1201: A terminal device determines a first transmission scheme to be used for transmitting a PUCCH from a plurality of transmission schemes.

[0182] In this embodiment of the present application, there are four transmission schemes used to transmit the PUCCH. The four transmission schemes are a first non-frequency hopping transmission scheme, a second non-frequency hopping transmission scheme, an intra-time unit frequency hopping transmission scheme, and an inter-time unit frequency hopping transmission scheme, respectively. Before transmitting or receiving the PUCCH, the terminal device may determine the first transmission scheme to be used to transmit or receive the PUCCH from the multiple transmission schemes. The multiple transmission schemes may include at least two of the aforementioned four transmission schemes. For example, the plurality of transmission schemes may include a first non-frequency hopping transmission scheme and a second non-frequency hopping transmission scheme; the plurality of transmission schemes may include a first non-frequency hopping transmission scheme and an intra-time-unit frequency hopping transmission scheme; the plurality of transmission schemes may include an inter-time-unit frequency hopping transmission scheme and a second non-frequency hopping transmission scheme; the plurality of transmission schemes may include an inter-time-unit frequency hopping transmission scheme and an intra-time-unit frequency hopping transmission scheme; the plurality of transmission schemes may include a first non-frequency hopping transmission scheme, a second non-frequency hopping transmission scheme, and an inter-time-unit frequency hopping transmission scheme; the plurality of transmission schemes may include inter-time-unit frequency hopping transmission, a second non-frequency hopping transmission scheme, and intra-time-unit frequency hopping transmission; or the plurality of transmission schemes may include a first non-frequency hopping transmission scheme, a second non-frequency hopping transmission scheme, an intra-time-unit frequency hopping transmission scheme, and an inter-time-unit frequency hopping transmission scheme. Alternatively, the plurality of transmission schemes includes a second non-frequency hopping transmission scheme and an intra-time-unit frequency hopping transmission scheme, and the plurality of transmission schemes does not include the first non-frequency hopping transmission scheme.

[0183] In this embodiment of this application, determining the first transmission method from the plurality of transmission methods includes the following two transmission methods:

[0184] Determination method 1: The terminal device may determine a first transmission method based on the instruction of the network device.

[0185] For example, in S1202, the network device transmits first indication information to the terminal device, and in response, the terminal device receives the first indication information. The first indication information may indicate any one of a plurality of transmission schemes, for example, the first transmission scheme. The first indication information may be carried by one or more of radio resource control (RRC) signaling, media access control element (MAC CE) signaling, downlink control information (DCI) signaling, or the like. The one or more fields may be fields defined in RRC signaling, fields defined in MAC CE signaling, or fields defined in DCI signaling, or may be RRC fields, MAC CE fields, or newly defined DCI fields. This is not limited in this embodiment of the application. Of course, the first indication information may alternatively be carried by newly defined signaling.

[0186] The first indication information may occupy one or more bits, and different bit states correspond to different PUCCH transmission schemes.

[0187] For example, the plurality of transmission schemes includes two transmission schemes, and the first indication information occupies one bit. For example, the plurality of transmission schemes includes a first non-frequency hopping transmission scheme and a second non-frequency hopping transmission scheme. A bit in a "0" state may indicate the first non-frequency hopping transmission scheme, and a bit in a "1" state may indicate the second non-frequency hopping transmission scheme. Alternatively, a bit in a "0" state may indicate the second non-frequency hopping transmission scheme, and a bit in a "1" state may indicate the first non-frequency hopping transmission scheme.

[0188] In another example, the plurality of transmission methods may include at least three transmission methods, and the first indication information may occupy at least two bits. For example, see Table 5 for specific indication contents of the first indication information.

[0189] [Table 5]

[0190] It can be understood that different terminal devices transmit PUCCHs separately in intra-slot frequency hopping transmission schemes and intra-slot non-frequency hopping transmission schemes. If the frequency domain resource corresponding to the PUCCH does not start from the lowest or highest frequency of the carrier bandwidth, resource fragmentation may occur, resulting in a low uplink transmission rate. In order to avoid uplink resource fragmentation as much as possible, this embodiment of this application provides a new scheme for determining the RB index of the PUCCH for the second non-frequency hopping transmission scheme.

[0191] In the example, the RB index of the PUCCH may be determined according to a first rule. For example, the first rule may be: 0≦r PUCCH ≦(X / 2)-1, and the RB index value of PUCCH is

number

number

number

number

[0192] In another example, the RB index of the PUCCH may be determined according to a second rule. For example, the second rule may be: 0≦r PUCCH ≦X-1, and the RB index value of PUCCH is

number

[0193] In yet another example, the RB index of the PUCCH may be determined according to a third rule. For example, the third rule may be: 0≦r PUCCH ≦X-1, and the RB index value of PUCCH is

number

[0194] It can be understood that X PUCCH resources are on one side of the BWP (or carrier) according to the second rule. X PUCCH resources are on the other side of the BWP (carrier) according to the third rule. In other words, X PUCCH resources may be concentrated on one side of the BWP (or carrier) according to the second rule or the third rule, i.e., X PUCCH resources are not distributed across two sides of the BWP. In this way, resource fragmentation of the BWP can be reduced or avoided as much as possible, thereby allowing more continuous resources to be allocated to terminal devices as much as possible, and reducing the impact on the transmission rate of the terminal devices.

[0195] Alternatively, the plurality of rules includes a first rule and a second rule. The first rule is a rule that satisfies the condition 0≦r PUCCH If ≦(X / 2)-1, the RB index of PUCCH is

number

number

[0196] The second rule is that 0≦r PUCCH If ≦X-1, the RB index of PUCCH is

number

number

[0197] In this case, according to the first rule, X / 2 PUCCH resources out of X PUCCH resources are on one side of the BWP (or carrier), and X / 2 PUCCH resources are on the other side of the BWP (carrier). X is a positive integer. For example, X=16. According to the second rule, X PUCCH resources out of 2X PUCCH resources are on one side of the BWP (or carrier), and X PUCCH resources are on the other side of the BWP (carrier). The second rule and the first rule may use the same formula structure. However, according to the second rule, if the PUCCH index indicated to the terminal device by the network device does not exceed X, the PUCCH resources of the terminal device will not be scattered across two sides of the BWP, and resource fragmentation of the BWP can be reduced. Therefore, more contiguous resources can be allocated to the terminal device to reduce the impact on the transmission rate of the terminal device.

[0198] For the second non-frequency hopping transmission scheme, the RB index of the PUCCH may be determined according to the first rule, the second rule, or the third rule. In this embodiment of the application, if the first transmission scheme indicated by the network device is the second non-frequency hopping transmission scheme, the network device may further indicate the RB index of the resource corresponding to the PUCCH. For example, the network device may indicate a rule to be used to determine the RB index of the PUCCH (referred to in this specification as the rule to be used) from at least two rules (i.e., multiple rules) among the first rule, the second rule, and the third rule.

[0199] In a first possible implementation, the first indication information may indicate both the second non-frequency hopping transmission scheme and the rule to be used. The terminal device may obtain the rule to be used based on the first indication information. The first indication information may occupy multiple bits. See Table 6 for an example. The first indication information may occupy two bits. In addition to indicating PUCCH transmission without frequency hopping, the first indication information further indicates a rule for determining resource blocks of the PUCCH, thereby flexibly indicating the PUCCH transmission scheme while reducing signaling overhead.

[0200] [Table 6]

[0201] It should be noted that Table 6 is merely an example. The correspondence between the bit state of the first indication information and the content indicated by the first indication information is not limited in this embodiment of this application. For example, another form of Table 6 can be represented as Table 7.

[0202] [Table 7]

[0203] In a second possible implementation, the first indication information may indicate a second non-frequency hopping transmission scheme, and the network device may indicate a rule to be used by using the second indication information. In this case, the network device may transmit the first indication information and the second indication information to the terminal device, and the terminal device correspondingly receives the first indication information and the second indication information. The terminal device may obtain a rule to be used based on the second indication information. See Table 8 for an example. The first indication information may occupy one bit. See Table 9. The second indication information may occupy two bits. Alternatively, see Table 10. The second indication information may occupy one bit.

[0204] [Table 8]

[0205] [Table 9]

[0206] [Table 10]

[0207] It should be noted that Tables 8 to 10 are merely examples. In this embodiment of the present application, the correspondence between the bit state of the first instruction information and the content indicated by the first instruction information is not limited, and the correspondence between the bit state of the second instruction information and the content indicated by the second instruction information is not limited.

[0208] Another implementation of this application is exemplified below. The first indication information indicates a PUCCH transmission scheme from a plurality of transmission schemes. The plurality of transmission schemes includes at least a second non-frequency hopping transmission scheme and an intra-time-unit frequency hopping transmission scheme. When the first indication information indicates that the PUCCH transmission scheme is the second non-frequency hopping transmission scheme, the network device may further transmit second indication information to the terminal device. The fact that the network device may further transmit the second indication information to the terminal device means that the second indication information may be present optionally. The network device may transmit the second indication information to the terminal device, or the network device may not transmit the second indication information to the terminal device. If the second indication information is present, the network device uses the second indication information to indicate a rule to be used by the terminal device to determine the RB index of the PUCCH from a plurality of rules. If the second indication information is present, the terminal device receives the second indication information and determines the rule to be used to determine the RB index of the PUCCH from a plurality of rules based on the indication of the second indication information. When the second indication information does not exist, the terminal device determines the RB index of the PUCCH according to a default rule and transmits the PUCCH. When the second indication information does not exist, the network device also determines the RB index of the PUCCH according to a default rule and receives the PUCCH. The terminal device may obtain identification information and determine whether the second indication information exists based on the identification information. For example, the identification information is a bit in ASN.1.

[0209] For example, the plurality of rules may include at least a second rule and a third rule. For example, the plurality of rules may include only a second rule and a third rule. For example, the plurality of rules may include only a first rule, a second rule, and a third rule. For example, the default rule is the first rule. It should be noted that the first rule, the second rule, and the third rule here have been described above, and the details will not be described again here.

[0210] Specific embodiments are provided below. For example, the first indication information is 1 bit. The multiple transmission schemes include a second non-frequency hopping transmission scheme and an intra-time-unit frequency hopping transmission scheme. When the bit of the first indication information is 0, the first indication information indicates that the PUCCH transmission scheme is the second non-frequency hopping transmission scheme. When the bit of the first indication information is 1, the first indication information indicates that the PUCCH transmission scheme is the intra-time-unit frequency hopping transmission scheme. When the PUCCH transmission scheme is the second non-frequency hopping transmission scheme, if the second indication information is present, the second indication information may instruct the terminal device to determine the RB index of the PUCCH according to one of two different rules. For example, the two different rules include a second rule and a third rule. For example, the second indication information is 1 bit. When the bit of the second indication information is 0, the second indication information instructs the terminal device to determine the RB index of the PUCCH according to the second rule. The bit of the second indication information is 1, and the second indication information instructs the terminal device to determine the RB index of the PUCCH according to the third rule.

[0211] When the PUCCH transmission scheme is the second non-frequency hopping transmission scheme, if the second indication information is not present, the terminal device determines the RB index of the PUCCH according to the default first rule. When the PUCCH transmission scheme is the second non-frequency hopping transmission scheme, if the second indication information is not present, the network device determines the RB index of the PUCCH according to the default first rule and receives the PUCCH. For example, the content indicated by the first indication information may be as shown in Table 11, and the content indicated by the second indication information may be as shown in Table 12.

[0212] [Table 11]

[0213] [Table 12]

[0214] It should be noted that the first indication information is upper layer signaling, and the second indication information is physical layer signaling. Alternatively, the first indication information is physical layer signaling, and the second indication information is upper layer signaling. Alternatively, the first indication information is upper layer signaling, and the second indication information is upper layer signaling. Alternatively, the first indication information is physical layer signaling, and the second indication information is physical layer signaling.

[0215] In a third possible implementation, the first indication information may indicate a second non-frequency hopping transmission scheme, and the network device may indicate a rule to be used by using third indication information. In this case, the network device may send the first indication information and the third indication information to the terminal device, and the terminal device correspondingly receives the first indication information and the third indication information. The terminal device may obtain a rule to be used based on the third indication information. In other words, if the first indication information indicates that the first transmission scheme is the second non-frequency hopping transmission scheme, the terminal device further obtains the third indication information.

[0216] In a possible implementation, the third indication information may indicate the value of m, and the terminal device may determine the RB index of the PUCCH based on the value of m. For example, 0≦r PUCCH ≦8m-1, and the RB index value of PUCCH is

number

number

[0217] For example, the first indication information may occupy 1 bit, and the indicated content may be represented in Table 8. The third indication information may occupy 1 bit, and the indicated content may be represented in Table 13. When the first transmission scheme is the second non-frequency hopping transmission scheme, the network device may send the third indication information, so that the PUCCH transmission scheme can be flexibly indicated while signaling overhead can be reduced.

[0218] [Table 13]

[0219] It may be understood that the third indication information and the first indication information may be the same signaling. The first indication information may also be considered to indicate the first transmission scheme and the value of m. Alternatively, the first indication information may indicate the value of m, and indirectly or implicitly indicate whether the PUCCH transmission scheme is the second non-frequency-hopping transmission scheme or the intra-time-unit frequency-hopping transmission scheme. For example, the first indication information occupies 1 bit. In the example, if the bit state of the first indication information is 0, m=1. Correspondingly, if the bit state of the first indication information is 1, m=2. When m=1, the PUCCH transmission scheme is the intra-time-unit frequency-hopping transmission scheme. When m=2, the PUCCH transmission scheme is the second non-frequency-hopping transmission scheme.

[0220] It should be noted that the first indication information is upper layer signaling, and the third indication information is physical layer signaling. Alternatively, the first indication information is physical layer signaling, and the third indication information is upper layer signaling. Alternatively, the first indication information is upper layer signaling, and the third indication information is upper layer signaling. Alternatively, the first indication information is physical layer signaling, and the third indication information is physical layer signaling.

[0221] In a fourth possible implementation, the network device may indicate the second rule or the third rule by using one-bit information. For example, the network device transmits fourth indication information to the terminal device, and one state of the fourth indication information corresponds to one rule. For example, the fourth indication information occupies one bit. The bit state of the fourth indication information is 0, and the RB index of the PUCCH is

number

number

[0222] It should be noted that the first indication information is upper layer signaling, and the fourth indication information is physical layer signaling. Alternatively, the first indication information is physical layer signaling, and the fourth indication information is upper layer signaling. Alternatively, the first indication information is upper layer signaling, and the fourth indication information is upper layer signaling. Alternatively, the first indication information is physical layer signaling, and the fourth indication information is physical layer signaling.

[0223] S1203: The terminal device transmits capability information to the network device, and in response, the network device receives the capability information, wherein the capability information indicates whether the terminal device supports a first non-frequency hopping transmission scheme, and / or the first capability information indicates whether the terminal device determines RB indices of the PUCCH according to a second rule, and / or the first capability information indicates whether the terminal device determines RB indices of the PUCCH according to a third rule, and / or the first capability information indicates whether the terminal device supports m=2.

[0224] The capability information indicating whether the terminal device supports the first non-frequency hopping transmission scheme can also be understood as the capability information being able to feedback whether the terminal device supports the first non-frequency hopping transmission scheme. Different terminal devices have different capabilities. Some terminal devices support the first non-frequency hopping transmission scheme, and some terminal devices do not support the first non-frequency hopping transmission scheme. It would obviously be inappropriate for the network device to instruct a terminal device that does not support the first non-frequency hopping transmission scheme to transmit a PUCCH in the first non-frequency hopping transmission scheme. Therefore, in this embodiment of the present application, the network device may determine the first transmission scheme from multiple transmission schemes based on the capability information reported by the terminal device to avoid a mismatch between the determined transmission scheme and the capabilities of the terminal device. Of course, if the terminal device does not transmit capability information to the network device, it may be considered that the terminal device supports the first non-frequency hopping transmission scheme by default. That is, S1203 is an optional step, represented by a dashed line in FIG. 12.

[0225] In some embodiments, the first indication information may alternatively indicate whether the terminal device supports an inter-time unit frequency hopping transmission scheme. The network device determines whether to instruct the terminal device to transmit the PUCCH in the inter-time unit frequency hopping transmission scheme based on the first indication information. Alternatively, in some embodiments, the first indication information may indicate whether the terminal device supports the first non-frequency hopping transmission scheme and the inter-time unit frequency hopping transmission scheme.

[0226] Similar to the first indication information, the capability information may alternatively be carried by one or more of RRC signaling, MAC CE signaling, UCI signaling, or the like. The one or more fields may be fields defined in RRC signaling, fields defined in MAC CE signaling, or fields defined in UCI signaling, or may be RRC fields, MAC CE fields, or newly defined UCI fields. This is not limited in this embodiment of the application. Of course, the capability information may also be carried by newly defined signaling.

[0227] It should be noted that the specific implementation of the capability information is not limited in this embodiment of the application. The capability information may directly indicate whether the terminal device supports the first non-frequency hopping transmission scheme and / or directly indicate whether the terminal device supports the inter-time-unit frequency hopping transmission scheme. For example, the first indication information and the capability information may be carried in different signaling or different fields of the same signaling. The capability information may indirectly indicate whether the terminal device supports the first non-frequency hopping transmission scheme and / or indirectly indicate whether the terminal device supports the inter-time-unit frequency hopping transmission scheme. For example, whether the terminal device supports the first non-frequency hopping transmission scheme may be indicated by indicating whether a field carrying capability information is present. The presence of a field carrying capability information may indicate that the terminal device does not support the first non-frequency hopping transmission scheme. Correspondingly, the absence of a field carrying capability information may indicate that the terminal device supports the first non-frequency hopping transmission scheme.

[0228] After receiving the first indication information from the network device, the terminal device may determine a transmission scheme to be used for PUCCH transmission according to Table 5. It should be understood that multiple terminal devices share PUCCH resources. In addition to determining the PUCCH transmission scheme, the terminal device also needs to determine the index of an orthogonal sequence whose length is Li, where i=1, 2, 3, 4, 5, or 6.

[0229] For example, if the terminal device uses a first non-frequency hopping transmission scheme, the terminal device needs to determine an index of an orthogonal sequence having a length of L1 for transmitting the first part of the UCI and an index of an orthogonal sequence having a length of L2 for transmitting the second part of the UCI, and / or the terminal device needs to determine an index of an orthogonal sequence having a length of L3 for transmitting the first part of the DMRS and an index of an orthogonal sequence having a length of L4 for transmitting the second part of the DMRS.

[0230] The network device may indicate the index of the orthogonal sequence by using index indication information to notify the terminal device of the orthogonal sequence for transmitting UCI and / or DMRS.

[0231] As described above, if it is pre-specified that the indices of orthogonal sequences having the same length are the same, for example, Li = Lj, the index of the orthogonal sequence having length Li is the same as the index of the orthogonal sequence having length Lj. The terminal only needs to determine the index of the orthogonal sequence having length Li to determine the index of the orthogonal sequence having length Lj, or the terminal only needs to determine the index of the orthogonal sequence having length Lj to determine the index of the orthogonal sequence having length Li. In this case, the network device may send index indication information, for example, first index indication information, to the terminal device to indicate the index of the orthogonal sequence having length Li. The terminal device may determine the index of the orthogonal sequence having length Li and the index of the orthogonal sequence having length Lj based on the first index indication information to determine the orthogonal sequence having length Li and the orthogonal sequence having length Lj.

[0232] The indexes of orthogonal sequences having different lengths are different. For example, if it is pre-specified that Li ≠ Lj, the index of the orthogonal sequence having length Li is different from the index of the orthogonal sequence having length Lj. In this case, the network device may separately indicate the index of the orthogonal sequence having length Li and the index of the orthogonal sequence having length Lj. For example, the network device transmits second index indication information and third index indication information to the terminal device. The second index indication information indicates the index of the orthogonal sequence having length Li, and the third index indication indicates the index of the orthogonal sequence having length Lj. To determine the orthogonal sequence having length Li and the orthogonal sequence having length Lj, the terminal device may determine the index of the orthogonal sequence having length Li based on the second index indication information and the index of the orthogonal sequence having length Lj based on the third index indication information.

[0233] Determination method 2: The terminal device determines the first transmission method according to a pre-specified rule (also referred to as a pre-set rule).

[0234] The pre-specified rule may be that a reduced-capability terminal device transmits a PUCCH in a first transmission scheme. Specifically, if a terminal device is a reduced-capability terminal device, the terminal device transmits a PUCCH in the first transmission scheme by default. The pre-specified rule may also be that if a reduced-capability terminal device determines that a normal terminal device transmits a PUCCH in a frequency hopping transmission scheme, the reduced-capability terminal device transmits a PUCCH in the first transmission scheme by default.

[0235] It should be understood that S1202 is an optional step because the terminal device may determine the first transmission method according to a preset rule. Therefore, dashed lines are used for illustration in FIG.

[0236] It should be understood that the network device may also receive the PUCCH from the terminal device according to a pre-specified rule. For example, if the network device determines to receive the PUCCH from the reduced-capability terminal device, the network device receives the PUCCH from the reduced-capability terminal device in a first transmission manner. If the network device determines to separately receive the PUCCH from the reduced-capability terminal device and the normal terminal device, and determines that the normal terminal device transmits the PUCCH in a frequency-hopping transmission manner, the network device receives the PUCCH from the reduced-capability terminal device in the first transmission manner.

[0237] S1204: The terminal device transmits the PUCCH in the determined first transmission manner, and the network device receives the PUCCH correspondingly.

[0238] After determining a PUCCH transmission scheme, for example, a first transmission scheme, and determining a related orthogonal sequence for transmitting the PUCCH, the terminal device may transmit or receive the PUCCH.

[0239] For example, a reduced-capability terminal device determines to transmit a PUCCH in an inter-time-unit frequency-hopping transmission manner. Since there is a certain number of symbols between the first and second hops of the PUCCH in the inter-time-unit frequency-hopping transmission manner, even if the reduced-capability terminal device transmits or receives a PUCCH in a frequency range that exceeds the maximum channel bandwidth capability of the reduced-capability terminal device, frequency readjustment can be performed for the certain number of symbols, and the transmission and / or reception of the PUCCH will not be affected. In this way, degraded PUCCH transmission performance of the reduced-capability terminal device can be avoided.

[0240] In another example, the reduced-capability terminal device determines to transmit the PUCCH using a first non-frequency hopping transmission scheme. The UCI and DMRS on the PUCCH are separately divided into two parts, so that the UCI and DMRS are transmitted without frequency hopping by using orthogonal sequences with the same or different lengths. Even if the normal terminal device and the reduced-capability terminal device share the PUCCH resource, the orthogonality between the PUCCH transmission of the normal terminal device and the PUCCH transmission of the reduced-capability terminal device can still be guaranteed to avoid interference with the PUCCH transmission of the normal terminal device and ensure the PUCCH transmission performance of the normal terminal device.

[0241] The foregoing embodiments of this application describe the methods provided in the embodiments of this application from the perspective of interaction between a terminal device and a network device. The steps performed by the network device may also be separately implemented by different communication devices. For example, a first device is configured to determine a first transmission scheme from multiple transmission schemes, and a second device is configured to transmit a PUCCH in the first transmission scheme. In other words, the first device and the second device jointly complete the steps performed by the network device in the embodiments of this application. This application does not limit a specific division scheme. When a network architecture includes one or more distributed units (DUs), one or more centralized units (CUs), and one or more radio frequency units (RUs), the steps performed by the network device may be separately implemented by the DU, CU, and RU. To implement the functions of the foregoing methods provided in the embodiments of this application, the network device and the terminal device may include hardware structures and / or software modules, and may implement the functions in the form of a hardware structure, a software module, or a combination of a hardware structure and a software module. Whether a particular function among the aforementioned functions is performed by a hardware structure, a software module, or a combination of a hardware structure and a software module depends on the particular application and design constraints of the technical solution.
