Background Art

[0003] In a time division duplexing (TDD) system, the downlink (DL) usually occupies the main time resources as shown in FIG. 1. This causes a coverage imbalance between the DL and the uplink (UL). Compared with a frequency division duplexing (FDD) system, the uplink coverage of the TDD system is poor and the latency is high. Subband full duplex (SBFD) proposed in the industry can solve these problems in the TDD system. Most companies support the solution of "subband full duplex on the network device side and half duplex on the terminal device side". Specifically, the network device may perform transmission and reception simultaneously on one symbol, the terminal device can only perform reception or transmission on one symbol, and cannot perform reception and transmission simultaneously on one symbol. In this way, the uplink transmission resources available to the terminal device can be increased, thereby effectively increasing the UL coverage and reducing the UL latency.

[0004] In wireless communication systems, uplink L1 / L2 control signaling, also known as uplink control information (UCI), is typically used to support data transmission over uplink and downlink transmission channels. In existing protocols, UCI is primarily transmitted over the physical uplink control channel (PUCCH), and the PUCCH resources used to transmit UCI may be configured by network devices. In scenarios where SBFD is introduced, network devices also need to configure PUCCH resources for transmitting UCI to ensure the successful transmission of data over uplink and downlink transmission channels.

[0005] Currently, configuration solutions for PUCCH resources in scenarios where SBFD is implemented are still being explored. [Overview of the project]

[0113] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0114] In the description of this application, terms such as “first” and “second” are used merely to distinguish different subjects and do not limit the number or order of execution. Furthermore, terms such as “first” and “second” do not indicate clear differences. For example, “first message,” “second message,” and similar terms are used merely to distinguish different information and do not limit the order of the first message, second message, and similar terms. In addition, the terms “includes” and “equipment” and any other variations thereof are intended to cover non-inclusive inclusions. For example, a process, method, system, product, or device comprising a series of steps or units is not limited to the listed steps or units, and may optionally further include steps or units not listed, or may optionally further include other steps or units specific to the process, method, product, or device.

[0115] In this description, unless otherwise specified, " / " means "or". For example, A / B may indicate A or B, and the term "and / or" in this specification describes only the relationship between the related subjects and indicates that there may be three relationships. For example, A and / or B may represent three cases: when only A is present, when both A and B are present, and when only B is present. Furthermore, "at least one item", "one or more of the following items", or similar expressions indicate any combination of these items, including any combination of singular or plural items. For example, at least one of a, b, or c may represent a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c may each be singular or plural.

[0116] In the description of this application, words such as “example” or “for example” are used to indicate that an example, illustration, or explanation is being given. Any embodiment or design scheme described as “example,” “etc.” or “for example” in this application should not be described as being preferable to or having more features than another embodiment or design scheme. Strictly speaking, the use of words such as “example,” “etc.” or “for example” is intended to present a relevant concept in a particular manner.

[0117] In the description of this application, both "when" and "in the case" mean that the device performs the corresponding process in an objective case, and are not intended to limit the time, nor do they require a decision action during the implementation of the device, nor do they imply that there are any other limitations.

[0118] In this application, "simultaneously" can be understood as the same point in time, within a certain period, or within the same period, and more specifically, it can be understood by referring to the context.

[0119] In this application, unless otherwise specified, elements indicated in the singular form are intended to indicate "one or more," but not "one and only one."

[0120] Furthermore, the terms "system" and "network" as used herein may be used interchangeably.

[0121] In embodiments of the present application, “A corresponds to B” may be understood to indicate that B is associated with A and that B can be determined based on A. However, it should be further understood that determining B based on A does not mean that B is determined solely based on A, and B can alternatively be determined based on A and / or other information.

[0122] In embodiments of this application, it can be understood that “indicate” and “indicate” may include direct and indirect indications, or explicit and implicit indications. The statement “specific indication information indicates A” or “indication information of A” may include direct or indirect indication of A, but does not necessarily mean that the indication information holds A, and the information indicated by the information is referred to as indicated information. In a particular implementation process, indicated information may be indicated in several ways. By example, and not by limitation, indicated information may be indicated directly, for example, by using indicated information or an index of indicated information. Alternatively, indicated information may be indicated indirectly by indicating other information, and there is a relationship between the other information and the indicated information. Alternatively, only a portion of indicated information may be indicated, and the other portion of indicated information is known or pre-agreed. For example, specific information may be indicated by using a pre-agreed (e.g., specified in a protocol) sequence of multiple pieces of information to reduce the indication overhead to some extent. In addition, common parts of all information may be indicated and identified in a unified manner to reduce the indication overhead that would arise from indicating the same information separately. Furthermore, a particular indication method may alternatively include, but is not limited to, the aforementioned indication methods and various combinations thereof, various existing indication methods. For details of various indication methods, refer to the prior art. Details are not described herein. From the foregoing, it can be understood that, for example, when it is necessary to indicate multiple pieces of information of the same type, different pieces of information may be indicated in different ways. In a particular implementation process, the required indication method may be selected based on specific requirements. The selected indication method is not limited to the embodiments of this application. Thus, the indication methods in the embodiments of this application should be understood to encompass various ways in which the indicated party may know the indicated information. The indicated information may be transmitted as a whole, or it may be divided into multiple sub-pieces of information for separate transmissions.In addition, the transmission cycle and / or transmission opportunities of these sub-informations may be the same or different. The specific transmission method is not limited in this application. The transmission cycle and / or transmission opportunities of these sub-informations may be predefined, for example, as predefined according to a protocol, or they may be configured by a transmitting end device transmitting configuration information to a receiving end device. For example, the configuration information may include, but is not limited to, one or at least two combinations of radio resource control signaling, MAC layer signaling, and physical layer signaling.

[0123] The technical solutions in the embodiments of this application can be applied to a variety of communication systems, including, for example, universal mobile telecommunications systems (UMTS), also known as third-generation (3G) systems; long-term evolution (LTE) systems, also known as fourth-generation (4G) systems; worldwide interoperability for microwave access (WiMAX®) communication systems; fifth-generation (5G) systems such as new radio (NR); networks integrating multiple systems; Internet of Things systems; Internet of Vehicle systems; and future communication systems such as 6G systems.

[0124] It should be understood that the network architecture described in the embodiments of this application is intended to more clearly describe the technical solutions in the embodiments of this application and does not constitute a limitation on the technical solutions provided in the embodiments of this application. Those skilled in the art will know that as network architectures evolve, the technical solutions provided in the embodiments of this application may also be applicable to similar technical problems.

[0125] Figure 2a is a diagram of the architecture of a communication system according to one embodiment of the present invention. As shown in Figure 2a, the communication system includes a wireless access network 100. The wireless access network 100 may include at least one wireless access network device (e.g., 110a and 110b in Figure 2a). The communication system may further include at least one terminal device (e.g., 120a to 120j in Figure 2a). The terminal devices may be connected to the wireless access network devices wirelessly. The terminal devices may be connected to each other by wired or wireless means, and the wireless access network devices may be connected to each other by wired or wireless means. Figure 2a may be understood as merely a diagram. The communication system may further include other network devices, for example, a core network device, a wireless relay device, and a wireless backhaul device not shown in Figure 2a.

[0126] A wireless access network device, also called a network device, is an access device used by a terminal to wirelessly access a communication system. A wireless access network device may be a base station (BS), an evolved NodeB (eNodeB, abbreviated as eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next-generation base station in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, an access node in a Wireless Fidelity (Wi-Fi®) system, or similar. Alternatively, a wireless access network device may be a module or unit that completes some functions of a base station, for example, a central unit (CU) or a distributed unit (DU). A base station including a CU and a DU may also be called a base station in which the CU and DU are separated from each other. For example, a base station may include a gNB-CU and a gNB-DU. A CU can be further divided into a CU control plane (CU-CP) and a CU user plane (CU-CP). For example, a base station may include a gNB-CU-CP, a gNB-CU-UP, and a gNB-DU. In this specification, a CU may perform the functions of the base station's radio resource control protocol and packet data convergence protocol (PDCP), and may also perform the functions of the service data adaptation protocol (SDAP). A DU may perform the functions of the base station's radio link control layer and medium access control (MAC) layer, and may also perform some or all of the functions of the physical layer.For a detailed explanation of the protocol layer described above, refer to the relevant technical specifications in the 3rd generation partnership project (3GPP®). The radio access network device may be a macro base station (e.g., 110a in Figure 2a), or a micro base station or indoor base station (e.g., 110b in Figure 2a), or a relay node or donor node. The specific technologies and device configurations used by the radio access network device are not limited to the embodiments of this application.

[0127] In embodiments of the present application, the device configured to implement the functions of a wireless access network device may be a wireless access network device, or a device capable of supporting a wireless access network device in implementing its functions, such as a chip system, a communication module, or a modem. The device may be installed on the wireless access network device. In the technical solutions provided in embodiments of the present application, the technical solutions provided in embodiments of the present application are described using the example where the device configured to implement the functions of a wireless access network device is a wireless access network device, and the wireless access network device is a base station. The base station may support the network using the same or different access technologies. The specific technologies and specific device forms used by the wireless access network device are not limited to embodiments of the present application.

[0128] A terminal device is a device having wireless transceiver functionality that can transmit signals to or receive signals from a base station. A terminal device may also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal, or similar. Terminal devices can be widely used in a variety of scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X), machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wear, smart transportation, and smart cities. A terminal may be a mobile phone, tablet computer, computer with wireless transceiver functionality, wearable device, vehicle, aircraft, ship, robot, robotic arm, smart home device, train detector, gas station sensor, or similar. The specific technologies and specific device forms used by the terminal are not limited to the embodiments of this application.

[0129] Base stations and terminals may be in a fixed location or may be mobile. Base stations and terminals may be deployed on land, including indoor or outdoor devices, handheld devices, or vehicle-mounted devices, or on water, or on an airplane, balloon, or satellite. Application scenarios for base stations and terminals are not limited to the embodiments of this application.

[0130] The roles of base stations and terminals can be relative. For example, the helicopter or unmanned aerial vehicle 120i in Figure 2a may be configured as a mobile base station. For terminal 120j accessing the radio access network 100 via 120i, terminal 120i is a base station. However, for base station 110a, 120i is a terminal. In other words, communication between 110a and 120i is performed according to the radio air interface protocol. Of course, communication between 110a and 120i may alternatively be performed according to the interface protocol between base stations. In this case, 120i is also a base station for 110a. Therefore, both base stations and terminals may be collectively referred to as communication devices, and 110a and 110b in Figure 2a may be referred to as communication devices having base station functions, while 120a through 120j in Figure 2a may be referred to as communication devices having terminal functions.

[0131] Communication between base stations and terminals, between base stations, or between terminals may be performed using licensed spectrum, or using unlicensed spectrum, or using both licensed and unlicensed spectrum. Communication may be performed using spectrum below 6 gigahertz (GHz), or using spectrum above 6 GHz, or using both spectrum below 6 GHz and spectrum above 6 GHz.

[0132] In embodiments of the present application, the device configured to implement the functions of a terminal may be a terminal, or a device capable of supporting the terminal in implementing functions, such as a chip system, a communication module, or a modem. The device may be installed within the terminal. In embodiments of the present application, the chip system may include a chip, or it may include a chip and other discrete components. In the technical solutions provided in embodiments of the present application, the technical solutions provided in embodiments of the present application are described using examples in which the device configured to implement the functions of a terminal is a terminal and the terminal is a UE. Specific technologies and specific device forms used by terminal devices are not limited to embodiments of the present application.

[0133] In some scenarios, the UE may be configured to function as a base station instead. For example, the UE may function as a scheduling entity providing sidelink signals between UEs in vehicle-to-vehicle / vehicle-to-infrastructure (V2X), device-to-device (D2D), peer-to-peer (P2P), or similar configurations.

[0134] In some scenarios, the UE may be configured to function as a relay node instead. For example, the UE may function as a relay device or an integrated access and backhaul (IAB) node, configured to provide wireless backhaul services for terminal devices.

[0135] Optionally, the method provided herein may be applied to V2X scenarios (e.g., the aforementioned scenario of communication between 120a and 120b in Figure 2a), and further to Sidelink UE-to-Network Relay scenarios and Sidelink UE-to-UE Relay scenarios. Figure 2b is a diagram of a Sidelink UE-to-Network Relay scenario according to an embodiment of the present invention. As shown in Figure 2b, the Sidelink UE-to-Network Relay scenario includes a remote UE and a relay UE, and further includes a base station. The method provided herein may be applied to communication between the remote UE and the relay UE. Figure 2c is a diagram of a Sidelink UE-to-UE Relay scenario according to an embodiment of the present invention. As shown in Figure 2c, the Sidelink UE-to-UE Relay scenario includes a source UE, a relay UE, and a target UE. The method provided herein may be applied to communication between a source UE and a relay UE and / or communication between a relay UE and a target UE.

[0136] Optionally, the method provided herein may be applied to a wireless communication system where the network device is subband full-duplex and the terminal device is half-duplex. For example, as shown in Figure 2d, there are two terminal devices within the coverage of the network device (the number of terminal devices in Figure 2d is merely an example, and there may be more or fewer terminal devices in an actual scenario). The SBFD time unit may be associated with two downlink subbands and one uplink subband. In the SBFD time unit, terminal device #0 transmits an uplink signal to the network device, and terminal device #1 receives a downlink signal transmitted by the network device.

[0137] Optionally, one or more antennas may be configured for a terminal device to receive and transmit data / information, as shown in Figures 2a to 2d. Similarly, one or more antennas may be configured for a radio access network device to receive and transmit data / information. It may be understood that the radio access network device and the terminal device may further include multiple components related to the transmission and reception of data / information (e.g., processors, modulators, multiplexers, demodulators, or demultiplexers). It may be understood further that Figures 2a to 2d are merely illustrations. The communication system may further include other devices not shown in Figures 2a to 2d, for example, a core network device, a radio relay device, and / or a radio backhaul device. It may be understood further that Figures 2a to 2d are merely examples. The number of radio access network devices and terminal devices included in the communication system is not limited to the embodiments of the present application.

[0138] In the embodiments of this application, the term "wireless communication" may be abbreviated to "communication," and the term "communication" may also be described as "data transmission," "information transmission," or "transmission."

For simplification, Figure 3 shows only the main components of the base station 110 (which may correspond to 110a and 110b in Figure 2a) and the UE 120 (which may correspond to 120a through 120j in Figure 2a). In actual application, the structure of the base station and UE may include more components than those shown in Figure 3, or fewer components than those shown in Figure 3, or only the components shown in Figure 3. It should be understood that the base station shown in Figure 3 may have a CU-DU partitioned architecture or a CU-DU non-partitioned architecture. For a simplified structure of the core network-side devices, please refer to the structure of the base station and UE. Further details will not be described again. Below, the components in Figure 3 are described separately and briefly.

[0147] The above description illustrates the architecture of a communication system to which the embodiments of this application can be applied. To better understand the technical solutions in the embodiments of this application, several terms or nouns related to this application are briefly explained below to facilitate understanding by those skilled in the art.

[0148] 1. Subband full duplex (SBFD)

[0149] In a subband full duplex (SBFD) solution, a single component carrier (CC) is divided into multiple subbands, and the transmission directions of the different subbands may differ, thereby enabling simultaneous transmission and reception on a single symbol. In a typical SBFD solution, as shown in Figure 4, the intermediate subband (e.g., subband 1 in Figure 4) is the uplink subband, and the two upper and lower subbands (e.g., subbands 0 and 2 in Figure 4) are the downlink subbands. In SBFD, it may be considered that different frequency domain resources (subbands) are used for uplink and downlink. In this solution, the uplink transmission resources available to terminal devices are increased, thereby effectively increasing UL coverage and reducing UL delay. In other words, after the introduction of SBFD, the frequency resource configuration of a single component carrier may include at least a downlink subband (DL subband) and an uplink subband (UL subband).

[0150] A guard band may be defined between the DL subband and the UL subband to reduce crosslink interference between downlink transmissions in the DL subband and uplink transmissions in the UL subband. In the embodiments of this application, whether or not a guard band exists between the DL subband and the UL subband is not particularly limited. Furthermore, if a guard band exists, whether or not it needs to be explicitly defined and whether or not transmission can be performed within the guard band is not particularly limited. Furthermore, in this application, whether or not the DL subband and the UL subband may overlap is not limited.

[0151] In this application, an SBFD time unit may be an SBFD symbol or an SBFD slot, and a non-SBFD time unit may be a non-SBFD symbol or a non-SBFD slot. An SBFD symbol may be considered a symbol composed of SBFD, and a non-SBFD symbol may be considered a symbol not composed of SBFD. An SBFD slot may be considered a slot composed of SBFD, and a non-SBFD slot may be considered a slot not composed of SBFD. Specifically, a non-SBFD symbol / slot may be an uplink symbol / slot, a downlink symbol / slot, or a flexible symbol / slot. For example, for downlink transmission, a non-SBFD symbol / slot may be a downlink symbol / slot or a flexible symbol / slot. For uplink transmission, a non-SBFD symbol / slot may be an uplink symbol / slot or a flexible symbol / slot. For example, in Figure 4, time unit 1 associated with subband 0, subband 1, and subband 2 is an SBFD time unit. The component carriers associated with time units 2 and 3 are not divided into subbands; the entire component carrier is used for uplink or downlink, and simultaneous reception and transmission on a single symbol is not supported. Therefore, time units 2 and 3 are non-SBFD time units.

[0152] For SBFD configurations, refer to the following two possible configurations, based on whether a single slot contains both SBFD and non-SBFD symbols:

[0153] (1) The SBFD configuration is at the slot level. Specifically, all symbols contained in a single slot are configured either as SBFD symbols or as non-SBFD symbols.

[0154] (2) The SBFD configuration is at the symbol level. Specifically, some symbols in a single slot may be configured as SBFD symbols, while other symbols may be configured as non-SBFD symbols.

[0155] 2. Uplink control information (UCI)

[0156] In a communication system, data transmission on uplink and downlink transmission channels must be supported using uplink L1 / L2 control signaling, which is also commonly referred to as uplink control information (UCI). UCI typically includes the following information: (1) hybrid automatic retransmission quest acknowledgment (HARQ-ACK) of a received downlink sharing channel (DL-SCH) transport block (TB); (2) channel statement information (CSI) relating to the downlink channel state, which may be used to assist in downlink scheduling and includes processes such as multi-antenna and beamforming solutions, as well as adaptive modulation and coding, and time-frequency resource allocation; and (3) scheduling requests (SR) indicating that the UE requires uplink resources for uplink sharing channel (UL-SCH) transmission.

[0157] 3. Physical uplink control channel (PUCCH)

[0158] Currently, UCI is primarily transmitted over PUCCH in communication systems. It should be noted that UCI may be transmitted not only over PUCCH but also over a physical uplink sharing channel (PUSCH). For example, for user equipment (UE), when PUSCH is transmitted at the same time as PUCCH transmission, UCI and data may be transmitted together over PUSCH, and PUCCH is not transmitted separately. Naturally, if UE is capable of transmitting PUCCH and PUSCH simultaneously, UE may also transmit UCI simultaneously over PUCCH and PUSCH.

[0159] NR defines PUCCH in multiple formats for transmitting different UCIs, and different PUCCH formats have different durations and different numbers of carried bits. For example, see Table 1 below. PUCCH format 0 and PUCCH format 2 have 1 or 2 time-domain symbols and may also be called short PUCCH formats. PUCCH format 1, PUCCH format 3, and PUCCH format 4 have 4 to 14 time-domain symbols and may also be called long PUCCH formats. Because the number of symbols is larger, the coverage performance of PUCCH in long PUCCH formats is usually better than that of PUCCH in short PUCCH formats. Table 1 NR PUCCH format [Table 1]

[0160] To support a more flexible PUCCH architecture, the concept of a PUCCH resource set is introduced to NR. A single PUCCH resource set may contain at least four PUCCH resources, each PUCCH resource corresponding to a single PUCCH format and all the necessary parameters of that format, such as time-domain resource information, frequency-domain resource information, code-domain resource information, coding information, and frequency-hopping information. For example, in NR, see Figure 5 for the architecture of PUCCH resources and PUCCH resource sets. PUCCH resource set #0 may contain up to 32 PUCCH resources, and another PUCCH resource set may contain up to 8 PUCCH resources. Furthermore, a single UE supports up to four PUCCH resource sets, and each PUCCH resource set may separately carry a specific number of bits of UCI within a given range. For example, PUCCH resource set #0 may carry up to 2 bits of UCI. Thus, PUCCH resource set #0 may contain only PUCCH resources in PUCCH formats 0 and 1. For other PUCCH resource sets, the number of bits carried in the UCI may be greater than 2. Therefore, these PUCCH resource sets may include PUCCH resources in other PUCCH formats besides formats 0 and 1. The maximum number of bits in the UCI carried in a PUCCH resource set may be determined by a network device (e.g., a base station) using signaling.

[0161] 4. Selection of PUCCH resource sets and PUCCH resources

[0162] (1) When the UE is ready to transmit the UCI, if the UCI contains HARQ-ACK information bits, the UE may first select a PUCCH resource set based on the number of bits in the UCI to be transmitted, and then select a PUCCH resource in the selected PUCCH resource set. The base station may indicate a specific PUCCH resource to be used by the terminal in the PUCCH resource set by using the PUCCH resource indicator field in the downlink control information (DCI). For example, if the number of bits in the UCI is less than or equal to 2, the UE may select PUCCH resource set #0 shown in Figure 5. If the number of bits in the UCI is greater than 2 and less than or equal to N2, the UE may select PUCCH resource set #1 shown in Figure 5. The selection of PUCCH resource sets #2 and #3 is not described herein. After the UE selects a PUCCH resource set, if the number of PUCCH resources in the PUCCH resource set is not greater than 8, the UE may directly determine which PUCCH resources should be used in the PUCCH resource set based on the PUCCH resource indicator field in the DCI. See Table 2 below for the relationship between the field value and the PUCCH resources. Table 2 [Table 2]

[0163] If the number of PUCCH resources in a PUCCH resource set is greater than 8, the UE may determine which specific PUCCH resources should be used in the PUCCH resource set based on both the PUCCH resource indicator field in the DCI and a predefined rule. For the predefined rule, see the following formula:

[0164]

[0165] (2) When the UE is ready to transmit UCI and the information does not contain HARQ-ACK information bits, for example, when the UCI contains CSI information and / or SR information, the PUCCH resource used by the UE may be semi-statically configured by a network device (e.g., a base station) using radio resource control (RRC) signaling. For example, the PUCCH resource may be configured in CSI report configuration information or SR configuration information distributed by the base station.

[0166] First, the technical problems to be specifically addressed in this application are analyzed and proposed. In current TDD systems, slots are classified into downlink slots, flexible slots, and uplink slots. Downlink slots are used for downlink transmission, and flexible slots may be used for downlink transmission, uplink transmission, guard period (GP), or reserved resources. Uplink slots are used for uplink transmission. The PUCCH configuration solution in current TDD systems is to provide a configuration of only one identical PUCCH resource set for all slots used for uplink transmission, that is, all slots used for uplink transmission are guaranteed to use the same PUCCH resource set. After the introduction of SBFD, slots may be classified into SBFD slots and non-SBFD slots. For details, refer to the PUCCH configuration solution in existing TDD systems. A configuration of only one identical PUCCH resource set is provided for all slots used for uplink transmission. However, this configuration lacks flexibility and the following problems may exist:

[0167] (1) Because the uplink and downlink subbands of the SBFD slot are closely adjacent, crosslink interference (CLI) is additionally introduced. As a result, when SBFD and non-SBFD slots transmit UCI using PUCCH resources in the same PUCCH resource set, the transmission performance of PUCCH in the SBFD slot is lower than that of PUCCH in the non-SBFD slot, affecting UCI transmission.

[0168] (2) In SBFD, the component carrier is divided into multiple subbands, with some subbands used for uplink and some for downlink. Therefore, the frequency resources of some PUCCH resources may fall outside the frequency range of the uplink subband, and these PUCCH resources cannot be used for transmission. In other words, there may be a problem where some PUCCH resources can be used for transmission in non-SBFD slots but cannot be used for transmission in SBFD slots.

[0169] Currently, configuration solutions for PUCCH resources in SBFD implementation scenarios are still under consideration. Therefore, how to provide configuration solutions for PUCCH resources in SBFD implementation scenarios is an urgent issue that needs to be resolved.

[0170] Accordingly, the present application provides a communication method and apparatus, as well as a readable storage medium. The network device may configure dedicated PUCCH resources for two types of time units, namely SBFD time units and non-SBFD time units, thereby improving PUCCH resource allocation flexibility and providing a basis for improving the transmission performance of PUCCH in SBFD time units. Furthermore, after the two types of PUCCH resources are configured separately, the same UCI may be allowed to be repeatedly transmitted over the PUCCH resource across SBFD time units (symbols / slots) and non-SBFD time units (symbols / slots), improving the transmission performance of PUCCH and the success rate of UCI transmission, and reducing UCI transmission delay. Furthermore, when the two types of PUCCH resources are configured separately, spatial relation information (or transmission configuration indicator state information) associated with PUCCH transmission for different time unit types may be configured separately, thereby allowing PUCCH in SBFD time units to be transmitted over more appropriate beams and improving the transmission performance of PUCCH.

[0171] To facilitate understanding, the technical solution provided by this application will be described below with reference to more attached drawings.

[0172] In this Application, unless otherwise specified, identical or similar parts of an embodiment or implementation are to be referenced from one another. In the embodiments and implementations / methods / implementation methods of the embodiments of this Application, unless otherwise specified or unless there is a logical contradiction, terms and / or descriptions are consistent and may be referenced from one another between different embodiments and between implementations / methods / implementation methods of the embodiments. Technical features of different embodiments and implementations / methods / implementation methods of the embodiments may be combined based on their internal logical relationships to form new embodiments, implementations, methods, or implementation methods. The following implementations of this Application are not intended to limit the scope of protection of this Application.

[0173] In embodiments of the present application, a network device may configure dedicated PUCCH resources for SBFD time units and non-SBFD time units, respectively, in multiple ways as shown in Figures 6a to 6c. The communication methods in Figures 6a to 6c may be applied to the network devices and terminal devices (UEs) in Figures 2a to 2d. In other words, the network devices and UEs in Figures 2a to 2d may be configured to support and perform the procedural steps of the methods shown in Figures 6a to 6c.

[0174] Figure 6a is a schematic flowchart of a communication method according to an embodiment of the present invention. As shown in Figure 6a, the communication method includes, but is not limited to, the following steps.

[0175] S601: A network device sends a first message to the UE, which indicates one or more first type PUCCH resource sets and one or more second type PUCCH resource sets, each first type PUCCH resource set comprising one or more first type PUCCH resources, each second type PUCCH resource set comprising one or more second type PUCCH resources, each first type PUCCH resource used by the terminal device to transmit uplink control information UCI in subband full-duplex SBFD time units, and each second type PUCCH resource used by the terminal device to transmit UCI in non-subband full-duplex non-SBFD time units.

[0176] In response, the UE receives the first message sent by the network device.

[0177] S602: The network device receives the first UCI on the first PUCCH resource in one or more first type PUCCH resources and / or on the second PUCCH resource in one or more second type PUCCH resources.

[0178] Accordingly, the UE transmits the first UCI on the first PUCCH resource in one or more first type PUCCH resources and / or on the second PUCCH resource in one or more second type PUCCH resources.

[0179] In Figure 6a, the network device configures PUCCH resources dedicated to SBFD time units and PUCCH resources dedicated to non-SBFD time units at the granularity of a PUCCH resource set. For example, the network device configures one or more first-type PUCCH resource sets for SBFD time units and one or more second-type PUCCH resource sets for non-SBFD time units. Optionally, each resource set in one or more first-type PUCCH resource sets may include some or all of one or more first-type PUCCH resources, and each resource set in one or more second-type PUCCH resource sets may include some or all of one or more second-type PUCCH resources.

[0180] Figure 6b is a schematic flowchart of another communication method according to one embodiment of the present invention. The communication method includes, but is not limited to, the following steps.

[0181] S611: The network device sends a first message to the UE, which indicates one or more first-type physical uplink control channel PUCCH resources and one or more second-type PUCCH resources, one or more first-type PUCCH resources to be used by the terminal device to transmit uplink control information UCI in subband full-duplex SBFD time units, and one or more second-type PUCCH resources to be used by the terminal device to transmit UCI in non-subband full-duplex non-SBFD time units.

[0182] In response, the UE receives the first message sent by the network device.

[0183] S612: The network device receives the first UCI on the first PUCCH resource in one or more first type PUCCH resources and / or on the second PUCCH resource in one or more second type PUCCH resources.

[0184] Accordingly, the UE transmits the first UCI on the first PUCCH resource in one or more first type PUCCH resources and / or on the second PUCCH resource in one or more second type PUCCH resources.

[0185] In Figure 6b, the network device configures PUCCH resources at the granularity of PUCCH resources, with PUCCH resources dedicated to SBFD time units and PUCCH resources dedicated to non-SBFD time units. For example, the network device configures one or more first-type PUCCH resources for SBFD time units and one or more second-type PUCCH resources for non-SBFD time units.

[0186] Optionally, if the network device subsequently needs to inform the UE of specific resources that may be used in SBFD time units and specific resources that may be used in non-SBFD time units in the form of resource sets, the network device may distribute configurations of two types of resource sets. One type of resource set in the two types of resource sets may be associated with some or all of one or more first-type PUCCH resources, and the other type of resource set may be associated with some or all of one or more second-type PUCCH resources. For example, a network device sends a second message to a terminal device, where the first message indicates one or more first-type PUCCH resource sets and one or more second-type PUCCH resource sets, where any PUCCH resource set in one or more first-type PUCCH resource sets includes one or more PUCCH resources in one or more first-type PUCCH resources, and any PUCCH resource set in one or more second-type PUCCH resource sets includes one or more PUCCH resources in one or more second-type PUCCH resources.

[0187] Figure 6c is a schematic flowchart of yet another communication method according to one embodiment of the present invention. The communication method includes, but is not limited to, the following steps.

[0188] S621: The network device sends a first message to the UE, which indicates one or more first type physical uplink control channel PUCCH resource sets and one or more second type PUCCH resource sets, where one or more first type PUCCH resource sets include one or more first type PUCCH resources, and one or more second type PUCCH resource sets include one or more second type PUCCH resources, where one or more first type PUCCH resource sets are used by terminal devices to transmit uplink control information UCI in subband full-duplex SBFD time units, and where one or more second type PUCCH resource sets are used by terminal devices to transmit UCI in non-subband full-duplex non-SBFD time units.

[0189] In response, the UE receives the first message sent by the network device.

[0190] S622: The network device receives the first UCI on the first PUCCH resource in one or more first type PUCCH resources and / or on the second PUCCH resource in one or more second type PUCCH resources.

[0191] Accordingly, the UE transmits the first UCI on the first PUCCH resource in one or more first type PUCCH resources and / or on the second PUCCH resource in one or more second type PUCCH resources.

[0192] In Figure 6c, the network device configures PUCCH resources dedicated to SBFD time units and PUCCH resources dedicated to non-SBFD time units at the granularity of a PUCCH resource set. Furthermore, during configuration, the network device may implicitly indicate the purpose of the PUCCH resources included in the PUCCH resource set by indicating the purpose of the PUCCH resource set. For example, the use of one or more Type 1 PUCCH resource sets by a terminal device to transmit uplink control information UCI in subband full-duplex SBFD time units may be understood as the use of one or more Type 1 PUCCH resources included in one or more Type 1 PUCCH resource sets by a terminal device to transmit uplink control information UCI in subband full-duplex SBFD time units. Optionally, each resource set in one or more first-type PUCCH resource sets may include some or all of one or more first-type PUCCH resources, and each resource set in one or more second-type PUCCH resource sets may include some or all of one or more second-type PUCCH resources.

[0193] It should be noted that a network device may configure PUCCH resources exclusively for SBFD time units and PUCCH resources exclusively for non-SBFD time units at the granularity of a PUCCH resource set; or it may configure PUCCH resources exclusively for SBFD time units and PUCCH resources exclusively for non-SBFD time units at the granularity of a PUCCH resource. This is not specifically limited in this application. A network device may directly indicate the purpose of a PUCCH resource, or it may implicitly indicate the purpose of a PUCCH resource set by indicating the purpose of the PUCCH resource set. This is not specifically limited in this application.

[0194] Optionally, in Figures 6a to 6c, an SBFD time unit may be an SBFD symbol or an SBFD slot, i.e., an SBFD time unit is a symbol or slot configured in SBFD; and a non-SBFD time unit may be a non-SBFD symbol or a non-SBFD slot, i.e., a non-SBFD time unit is a symbol or slot not configured in SBFD. It should be noted that a PUCCH resource dedicated to an SBFD time unit (e.g., one or more first-type PUCCH resources) may be considered a PUCCH resource used for transmission over an SBFD symbol / slot, and a PUCCH resource dedicated to a non-SBFD time unit (e.g., one or more second-type PUCCH resources) may be considered a PUCCH resource used for transmission over a non-SBFD symbol / slot. A non-SBFD symbol / slot configured in a PUCCH resource may be an uplink symbol / slot, a flexible symbol / slot, or similar.

[0195] Optionally, a first PUCCH resource used to receive and transmit a first UCI may include at least one of a time-domain resource, a frequency-domain resource, a code-domain resource, or a spatial-domain resource, and a second PUCCH resource used to receive and transmit a first UCI may include at least one of a time-domain resource, a frequency-domain resource, a code-domain resource, or a spatial-domain resource. Furthermore, optionally, each of one or more first-type PUCCH resources may include a frequency-domain resource, and the frequencies of these PUCCH resources are within the frequency range of the uplink subband associated with the SBFD time unit, thus avoiding the problem that a PUCCH resource cannot be used for transmission in the SBFD time unit because the frequency resource is outside the range of the uplink subband.

[0196] To facilitate understanding, the following describes how a network device performs PUCCH resource configuration at the granularity of PUCCH resource sets. For example, as shown in Figure 7, a network device may configure X PUCCH resource sets (corresponding to one or more first-type PUCCH resource sets) dedicated to SBFD time units, and Y PUCCH resource sets (corresponding to one or more second-type PUCCH resource sets) dedicated to non-SBFD time units, where both X and Y are positive integers. X may be greater than Y, X may be less than Y, or X may be equal to Y. Optionally, for two types of PUCCH resource sets, the network device may independently configure the PUCCH resources contained in the two types of PUCCH resource sets, as well as independently configure the maximum load size of each PUCCH resource set. In other words, the network device may independently configure the maximum number of UCI bits that may be carried in each PUCCH resource set.

[0197] In possible implementations, when configuring PUCCH resources in a PUCCH resource set, the network device may first configure all PUCCH resources that may be used by the network device. For example, the network device may first configure a dedicated resource ID for each PUCCH resource in the PUCCH resources that may be used. Then, when configuring a PUCCH resource set, the network device may associate one or more PUCCH resources in these PUCCH resources in the configuration of each PUCCH resource set. For example, resource IDs corresponding to one or more PUCCH resources are configured in each PUCCH resource set. The following briefly describes the process of configuring PUCCH resources dedicated to SBFD time units and PUCCH resources dedicated to non-SBFD time units at the granularity of a PUCCH resource set. See the following method:

[0198] Method 1:

[0199] A network device configures J PUCCH resources using a first signaling, where J PUCCH resources are resources that may be used by the network device, and J is a positive integer. When a network device configures X sets of PUCCH resources dedicated to SBFD time units and / or Y sets of PUCCH resources dedicated to non-SBFD time units, all X sets of PUCCH resources dedicated to SBFD time units and / or Y sets of PUCCH resources dedicated to non-SBFD time units are associated with all or part of the J PUCCH resources.

[0200] Method 2:

[0201] A network device configures J PUCCH resources and K PUCCH resources by using a first signaling and a second signaling, respectively, where J PUCCH resources and K PUCCH resources are resources that may be used by the network device, and both J and K are positive integers. If a network device configures X sets of PUCCH resources dedicated to SBFD time units and Y sets of PUCCH resources dedicated to non-SBFD time units, the X sets of PUCCH resources dedicated to SBFD time units may be associated with all or some of the J PUCCH resources, and the Y sets of PUCCH resources dedicated to non-SBFD time units may be associated with all or some of the K PUCCH resources.

[0202] Furthermore, for dedicated PUCCH resources in the two types of PUCCH resource sets mentioned above, the network device may independently configure dedicated parameters for each PUCCH resource, such as the PUCCH format, whether intra-slot frequency hopping is supported, the frequency domain start position, the frequency domain position of the second frequency hop (if frequency hopping is supported), the number of physical resource blocks (PRBs), the length and index of the time domain orthogonal cover code (OCC), the number of time domain symbols, the start symbol, and the initial cyclic shift. Optionally, common parameters specific to the PUCCH format may be further independently configured, such as whether inter-slot frequency hopping is supported, whether additional DMRS is supported, the maximum coding rate, the number of transmission slots, whether π / 2 BPSK modulation is supported, and whether simultaneous transmission of HARQ-ACK and CSI is supported.

[0203] If a network device optionally configures each PUCCH resource, it may configure a PUCCH resource dedicated to SBFD time units (e.g., the first PUCCH resource) with a longer time-domain duration, for example, a larger number of slots and / or a larger number of symbols within slots, compared to a PUCCH resource dedicated to non-SBFD time units (e.g., the second PUCCH resource). In other words, the time-domain resource length of the first PUCCH resource is greater than the time-domain duration of the second PUCCH resource. PUCCH resources corresponding to PUCCH formats 0 / 1 / 2 / 3 / 4 may be configured in this way. A longer time-domain duration means greater received energy or a lower received coding rate, which helps improve the transmission performance of the PUCCH.

[0204] If a network device optionally constitutes each PUCCH resource, the network device may constitute a wider frequency resource width for the PUCCH resources dedicated to SBFD time units, for example, a larger number of resource blocks (resource blocks, RBs), compared to a PUCCH resource dedicated to non-SBFD time units. In other words, the frequency resource width of the first PUCCH resource is greater than that of the second PUCCH resource. Wider frequency resources mean greater received energy, a lower received coding rate, or a longer orthogonal sequence, which helps improve the transmission performance of the PUCCH.

[0205] If a network device optionally configures each PUCCH resource, it may configure a lower maximum coding rate for PUCCH resources dedicated to SBFD time units compared to PUCCH resources dedicated to non-SBFD time units. In other words, the maximum coding rate of the first PUCCH resource is smaller than that of the second PUCCH resource, and a lower receive coding rate helps improve the transmission performance of the PUCCH. For example, a network device may configure a lower maximum coding rate for PUCCH resources corresponding to PUCCH formats 2 / 3 / 4.

[0206] If a network device optionally constitutes each PUCCH resource, it may constitute more demodulation reference signal (DMRS) symbols for a PUCCH resource dedicated to SBFD time units compared to a PUCCH resource dedicated to non-SBFD time units. In other words, the number of DMRS symbols for the first PUCCH resource may be greater than the number of DMRS symbols for the second PUCCH resource, and more DMRS symbols help improve the demodulation performance of the PUCCH, and further improve the transmission performance of the PUCCH. For example, a network device may constitute a larger number of DMRS symbols for PUCCH resources corresponding to PUCCH formats 1 / 2 / 3 / 4.

[0207] In possible implementations, when configuring each PUCCH resource, the network device may also configure spatial relation information (or transmission configuration indicator state information) associated with the PUCCH resource. Optionally, the network device may independently configure spatial relation information (or transmission configuration indicator state information) associated with PUCCH transmission in SBFD time units (corresponding to the first PUCCH resource) and spatial relation information (or transmission configuration indicator state information) associated with PUCCH transmission in non-SBFD time units (corresponding to the second PUCCH resource). For example, the spatial relation information (or transmission configuration indicator state information) configured for one or more first-type PUCCH resources and the spatial relation information (or transmission configuration indicator state information) configured for one or more second-type PUCCH resources may be the same or different. As another example, the spatial relation information (or transmission configuration indicator state information) configured for each resource in one or more first type PUCCH resources may be the same or different, and the spatial relation information (or transmission configuration indicator state information) configured for each resource in one or more second type PUCCH resources may be the same or different. In embodiments of the present application, the network device independently configures spatial relation information associated with PUCCH transmission in SBFD time units and spatial relation information associated with PUCCH transmission in non-SBFD time units, thereby enabling PUCCH in SBFD time units to be transmitted via a more suitable beam (e.g., with less CLI interference), reducing or avoiding the effects of CLI on PUCCH transmission, and improving the transmission performance of PUCCH in SBFD time units.

[0208] Optionally, the spatial relationship information (or transmission configuration indicator state information) may include reference signals associated with the PUCCH, such as a sounding reference signal (SRS), a channel statement information reference signal (CSI-RS), or a synchronization signal / PBCH block (SSB). Further optionally, the spatial relationship information (or transmission configuration indicator state information) may further include power control parameters of the PUCCH, such as an open-loop parameter Po, a closed-loop parameter, and a closed-loop process index.

[0209] For information on how to configure or activate PUCCH's spatial relationship information, please refer to the following example methods:

[0210] (1) In scenarios where a network device may explicitly configure spatial relationship information (spatial settings), refer to the following two possible activation methods regarding whether or not the PUCCH resource is configured for two different time units (symbols / slots):

[0211] 1. In a scenario where dedicated PUCCH resources are configured for two types of time units (symbols / slots), namely SBFD time units (symbols / slots) and non-SBFD time units (symbols / slots), the network device may use a medium access control-control element (MAC-CE) to indicate the spatial relationship information of the PUCCH resources used for transmission in the different types of time units. For example, the network device sends a third message to indicate the reference signals associated with the first PUCCH resource and the reference signals associated with the second PUCCH resource. Alternatively, the network device may use different MAC-CEs to indicate the spatial relationship information of the PUCCH resources used for transmission in the different types of time units. For example, the network device sends a third message and a fourth message, where the third message indicates the reference signal associated with the first PUCCH resource and the fourth message indicates the reference signal associated with the second PUCCH resource.

[0212] 2. In a scenario where different PUCCH resources are not configured for two different time units (symbols / slots), namely SBFD time units (symbols / slots) and non-SBFD time units (symbols / slots), i.e., where a network device does not configure dedicated PUCCH resources for SBFD time units and non-SBFD time units respectively, resources in the same set of PUCCH resources are used for two different time units. The network device may use MAC-CE to instruct two spatial relational pieces of information for a PUCCH resource, where the two pieces of spatial relational pieces of information are used respectively for the transmission of the PUCCH resource in two different types of time units (symbols / slots).

[0213] (2) In scenarios where the network device does not explicitly configure spatial relationship information (spatial settings), regardless of whether the dedicated PUCCH resource is configured in two types of time units (symbols / slots), namely SBFD time units (symbols / slots) and non-SBFD time units (symbols / slots), the spatial relationship information of a PUCCH transmission performed in each of the two different types of time units (symbols / slots) is the same as the spatial relationship information of a PDCCH transmission performed in the same type of time unit (symbol / slot). See Figure 8. The spatial relationship information of PUCCH in an SBFD slot and the spatial relationship information of PDCCH in an SBFD slot are the same, and the spatial relationship information of PUCCH in a non-SBFD slot and the spatial relationship information of PDCCH in a non-SBFD slot are the same. For example, the reference signal associated with the first PUCCH resource is identical to the reference signal associated with the first physical downlink control channel PDCCH, which is received by the terminal device in SBFD time units, and the first PDCCH is received by the terminal device in a control resource set CORESET with the minimum index value in the active downlink bandwidth portion BWP corresponding to the SBFD time unit; and the reference signal associated with the second PUCCH resource is identical to the reference signal associated with the second PDCCH, which is received by the terminal device in a non-SBFD time unit, and the second PDCCH is received by the terminal device in a CORESET with the minimum index value in the active downlink BWP corresponding to the non-SBFD time unit.

[0214] The first message used by the network device to optionally deliver PUCCH resources dedicated to SBFD time units and PUCCH resources dedicated to non-SBFD time units to the UE may be an RRC signaling, a System Information Block 1 (SIB1) signaling, or similar. It should be noted that the network device may deliver the configurations of PUCCH resources dedicated to both time units to the UE using a single signaling, or it may deliver the configurations of PUCCH resources dedicated to both time units multiple times using multiple signalings. This is not specifically limited herein.

[0215] After distributing dedicated PUCCH resources to terminal devices in two different time units (corresponding to steps S601, S611, or S621), the network device may then receive UCIs uploaded by terminal devices on these PUCCH resources, that is, on the first PUCCH resources in one or more first-type PUCCH resources and / or on the second PUCCH resources in one or more second-type PUCCH resources (corresponding to steps S602, S612, or S622).

[0216] In possible implementations, after the UE receives one or more first-type PUCCH resource sets and one or more second-type PUCCH resource sets (or one or more first-type PUCCH resources and one or more second-type PUCCH resources), the UE may repeatedly transmit the UCI to be transmitted (corresponding to the first UCI) over SBFD and non-SBFD time units.

[0217] Optionally, the UE may repeatedly transmit the first UCI N times on a first PUCCH resource corresponding to an SBFD time unit, and may repeatedly transmit the first UCI M times on a second PUCCH resource corresponding to a non-SBFD time unit. The first PUCCH resource belongs to one or more first type PUCCH resources, the second PUCCH resource belongs to one or more second type PUCCH resources, and both M and N are integers greater than 0. Accordingly, network devices receive the first UCI repeatedly transmitted by the UE on PUCCH resources (including the first and second PUCCH resources) corresponding to different time units. In embodiments of the present application, the UE repeatedly transmits the same UCI information on different PUCCH resources in two different time units, respectively, to improve PUCCH transmission performance, improve UCI transmission success rate, and reduce UCI transmission delay.

[0218] For example, the UE may initially determine which PUCCH resource (corresponding to the first PUCCH resource) will be used to transmit the first UCI in SBFD time units and which PUCCH resource (corresponding to the second PUCCH resource) will be used to transmit the first UCI information in non-SBFD time units. The UE then repeatedly transmits the first UCI in SBFD and non-SBFD time units based on the determined one or more PUCCH resources. For example, as shown in Figure 9, the UE may decide to use PUCCH resource #X in SBFD time units (symbol / slot) and PUCCH resource #Y in non-SBFD time units (symbol / slot), and associate PUCCH resource #X with PUCCH resource #Y. Furthermore, for M+N repeated transmissions, the UE may repeatedly transmit the first UCI information N times on PUCCH resource #X and repeatedly transmit the first UCI information M times on PUCCH resource #Y.

[0219] For example, an SBFD time unit may include SBFD slot 1, SBFD slot 2, ..., and SBFD slot N, and a non-SBFD time unit may include non-SBFD slot 1, non-SBFD slot 2, ..., and non-SBFD slot M, and for M+N repeated transmissions, the UE may transmit the UCI once separately in each of SBFD slot 1, SBFD slot 2, ..., and SBFD slot N on PUCCH resource #X, and also transmit the UCI once separately in each of non-SBFD slot 1, non-SBFD slot 2, ..., and non-SBFD slot M on PUCCH resource #Y. It can also be understood that the UE may transmit the UCI separately on multiple SBFD symbols and non-SBFD symbols. Further details are not described herein.

[0220] It should be noted that the UE may repeatedly transmit the UCI across SBFD and non-SBFD time units, or transmit the UCI only in SBFD time units, or transmit the UCI only in non-SBFD time units. For example, the UE transmits the first UCI on the first PUCCH resource in one or more first type PUCCH resources, or on the second PUCCH resource in one or more second type PUCCH resource sets. Correspondingly, the network device receives the first UCI transmitted by the terminal device on the first PUCCH resource in one or more first type PUCCH resources, or on the second PUCCH resource in one or more second type PUCCH resources.

[0221] For information on how the UE determines which PUCCH resources are used to transmit UCI in SBFD and non-SBFD time units, please refer to the following scheme:

[0222] (1) When UCI information includes HARQACK information

[0223] In a possible implementation, the network device delivers a DCI, which includes one indicator field (corresponding to a first PUCCH resource indicator field), and the UE may determine which PUCCH resources are used in SBFD and non-SBFD time units, respectively, based on the indicator field in the DCI delivered by the network device.

[0224] In a possible implementation, the network device delivers a DCI, which includes two indicator fields (corresponding to a first PUCCH resource indicator field and a second PUCCH resource indicator field), and the UE may determine which PUCCH resources are used in SBFD and non-SBFD time units, respectively, based on the two indicator fields in the DCI delivered by the network device. For example, one of the two indicator fields in the DCI may reuse an existing PUCCH resource indicator field, while the other indicator field may be a newly introduced indicator field, for example, referred to as the second PUCCH resource indicator field. The former is associated with non-SBFD time units and indicates the PUCCH resources used in non-SBFD time units. The latter (i.e., the newly introduced indicator field) is associated with SBFD time units and indicates the PUCCH resources used in SBFD time units.

[0225] Optionally, before determining the PUCCH resources to be used based on the indicator fields held in the DCI, the UE may first determine the PUCCH resource set to be used based on the number of bits in the UCI information to be transmitted. For the method by which the UE determines the PUCCH resource set when the network device does not constitute two types of dedicated PUCCH resource sets, please refer to the prior art. Details are not described again herein. If the network device constitutes two types of dedicated PUCCH resource sets, i.e., one or more first-type PUCCH resource sets and one or more second-type PUCCH resource sets, the UE determines the PUCCH resource set used in SBFD time units and the PUCCH resource set used in non-SBFD time units, respectively. In possible implementations, the UE determines the PUCCH resource set in one or more first-type PUCCH resource sets and the PUCCH resource set in one or more second-type PUCCH resource sets, respectively, based on the number of bits in the UCI information to be transmitted. Next, the UE separately determines the specific PUCCH resource to be used in the corresponding PUCCH resource set based on the indicator field in the DCI. For details on how the UE determines the corresponding PUCCH resource set based on the number of bits in the UCI and how it determines the specific PUCCH resource based on the indicator field in the DCI, please refer to the relevant description in "Selection of PUCCH Resource Sets and PUCCH Resources" above. Further details are not described again herein.

[0226] It should be noted that the method described above is applicable to both dynamic scheduling scenarios for physical downlink shared channels (PDSCHs) and semi-persistent scheduling scenarios for PDSCHs.

[0227] (2) When UCI information does not include HARQ-ACK information but includes CSI information and / or SR information

[0228] In this scenario, the network device may configure PUCCH resources used by the UE to transmit UCI in SBFD and non-SBFD time units, respectively, by using RRC signaling. Specifically, the network device may send a seventh message, which indicates a first PUCCH resource and a second PUCCH resource, and which instructs the terminal device to transmit the first UCI on the first and second PUCCH resources. For example, if the UCI information to be transmitted is a CSI report or SR, the network device may include in the CSI report configuration information or SR configuration information the PUCCH resources used to transmit UCI in SBFD and non-SBFD time units, respectively. Optionally, the seventh message may be a radio resource control RRC signaling, a system information block (SIB), or a MAC-CE. This is not specifically limited herein.

[0229] After SBFD is introduced, network devices may configure dedicated PUCCH resources for two different time units, namely SBFD time units and non-SBFD time units; or they may not configure dedicated PUCCH resources for SBFD time units and non-SBFD time units, and it should be noted that the same PUCCH resources are used for both time units.

[0230] In possible implementations, if a network device does not configure dedicated PUCCH resources for two different time units, namely SBFD time units and non-SBFD time units, the UE may repeatedly transmit UCI separately for SBFD time units and non-SBFD time units on the same PUCCH resource. Correspondingly, the network device may receive UCI repeatedly transmitted by the UE for different time units on the same PUCCH resource.

[0231] Figure 10 is a schematic flowchart of yet another communication method according to an embodiment of the present invention. The communication method includes, but is not limited to, the following steps.

[0232] S701: The network device sends a fifth message to the UE, which indicates one or more PUCCH resources, which are used by the terminal device to transmit UCI in SBFD and non-SBFD time units.

[0233] S702: A network device receives a second UCI that has been repeatedly transmitted N times by a terminal device in SBFD time units on a third PUCCH resource, and receives a second UCI that has been repeatedly transmitted M times by a terminal device in non-SBFD time units on the third PUCCH resource, where the third PUCCH resource belongs to one or more PUCCH resources, and both M and N are integers greater than 0, and when the second UCI is repeatedly transmitted N times in SBFD time units on the third PUCCH resource, the same spatial relationship is applied to each transmission, and when the second UCI is repeatedly transmitted M times in non-SBFD time units on the third PUCCH resource, the same spatial relationship is applied to each transmission.

[0234] Optionally, a network device may use MAC-CE to instruct two spatial relational information for a PUCCH resource, where the two spatial relational information are used for the transmission of the PUCCH resource in two different types of time units (symbols / slots). For example, the network device sends a sixth message, where the sixth message instructs the spatial relation corresponding to the third PUCCH resource in an SBFD time unit and the spatial relation corresponding to the third PUCCH resource in a non-SBFD time unit. The network device may configure the same or different spatial relation for the same PUCCH resource in different time units. This is not specifically limited herein.

[0235] Optionally, in step S701, the network device performs configuration at the granularity of PUCCH resources. If the network device then needs to inform the UE of specific resources that can be used in SBFD and non-SBFD time units in the form of resource sets, the network device may distribute a configuration of resource sets. A resource set may be associated with some or all of the aforementioned first PUCCH resources. It should be noted that the network device may alternatively perform configuration at the granularity of PUCCH resource sets. This is not specifically limited herein. For specific configurations, see the relevant descriptions in Figures 6a and 6c. Further details are not described again herein.

[0236] It should be noted that the UE may repeatedly transmit UCI over SBFD and non-SBFD time units on the same PUCCH resource, or transmit UCI only in SBFD time units, or transmit UCI only in non-SBFD time units. For example, the UE may transmit a second UCI over a third PUCCH resource in an SBFD time unit, or transmit a second UCI over a third PUCCH resource in a non-SBFD time unit. Correspondingly, the network device receives the second UCI transmitted by the terminal device over the third PUCCH resource in an SBFD time unit, or over the third PUCCH resource in a non-SBFD time unit.

[0237] In conclusion, in the embodiments described above, the network device may configure dedicated PUCCH resources for two types of time units, namely SBFD time units and non-SBFD time units, thereby improving PUCCH resource allocation flexibility and providing a basis for improving PUCCH transmission performance in SBFD time units. In addition, after the two types of PUCCH resources are configured separately, the same UCI may be allowed to be repeatedly transmitted over the PUCCH resources across SBFD time units (symbols / slots) and non-SBFD time units (symbols / slots), improving PUCCH transmission performance and UCI transmission success rate, and reducing UCI transmission delay. Furthermore, when the two types of PUCCH resources are configured separately, spatial relation information (or transmission configuration indicator state information) associated with PUCCH transmission for different time unit types may be configured separately, thereby enabling PUCCH in SBFD time units to be transmitted over more appropriate beams and improving PUCCH transmission performance.

The integrated module may be implemented in hardware form or in the form of a software functional module. It should be noted that in this application, the division into modules is an example and merely a logical functional division. In actual implementations, other division methods may be used. The device in the embodiment of this application will now be described with reference to the accompanying drawings.

[0291] It should be noted that the functions of the functional units / modules of the communication device described in the embodiments of this application should be referred to in the relevant descriptions in the method embodiments described above. Further details are not described again herein.

[0292] The specific descriptions of the receiving unit, transmitting unit, and processing unit shown in the above-described apparatus embodiments should be understood as merely examples. For specific functions, steps performed, or similar aspects of the receiving unit, transmitting unit, and processing unit, please refer to the description of any one of the method embodiments in Figures 6a to 6c or Figure 10. Further details are not described again herein.

[0293] The preceding paragraph describes the communication device in the embodiments of the present application, and the following describes possible product forms of the communication device. It should be understood that any form of product having the functionality of the communication device shown in Figure 11 is covered within the scope of protection of the embodiments of the present application. It should be further understood that the following description is merely an example and does not limit the product form of the communication device in the embodiments of the present application.

[0294] In a possible implementation, in the communication device shown in FIG. 11, the processing unit 102 (not shown in FIG. 11) may be one or more processors; the transmitting unit 100 and the receiving unit 101 may be transceivers; or, the transmitting unit 100 may be a transmitter and the receiving unit 101 may be a receiver. In an embodiment of the present application, the processor and the transceiver may be combined or similar operations may be performed. The connection method between the processor and the transceiver is not limited in the embodiment of the present application. In the process of executing the above method, the process of transmitting information in the above method may be understood as a process of outputting information by the processor. When outputting information, the processor outputs the information to the transceiver, and as a result, the transceiver transmits the information. After the information is output by the processor and before the information reaches the transceiver, other processing may need to be further performed on the information. Similarly, the process of receiving information in the above method may be understood as a process of receiving input information by the processor. When the processor receives the input information, the transceiver receives the information and inputs the information to the processor. Furthermore, after the transceiver receives the information and before the information is input to the processor, other processing may need to be performed on the information.

[0295] FIG. 12 is a structural diagram of another communication device according to an embodiment of the present application. The communication device 20 may be the communication device 10 or a chip in the communication device 10. FIG. 12 shows only the main components of the communication device 20. In addition to the processor 1001 and the transceiver 1002, the communication device 20 may further include a memory 1003 and an input / output device (not shown in the figure).

[0296] The processor 1001 is primarily configured to process communication protocols and communication data, control the entire communication device, execute software programs, and process data from the software programs. The memory 1003 is primarily configured to store software programs and data. The transceiver 1002 may include a control circuit and an antenna. The control circuit is primarily configured to perform conversions between baseband signals and radio frequency signals and to process radio frequency signals. The antenna is primarily configured to transmit and receive radio frequency signals in the form of electromagnetic waves. Input / output devices, such as touchscreens, displays, or keyboards, are primarily configured to receive data entered by the user and output data to the user.

[0297] After the communication device is powered on, the processor 1001 can read the software program in the memory 1003, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processor 1001 performs baseband processing on the data to be transmitted and outputs a baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal to the outside in the form of electromagnetic waves through the antenna. When data is transmitted to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal to a baseband signal, and outputs the baseband signal to the processor 1001. The processor 1001 converts the baseband signal into data and processes this data.

[0298] In an alternative implementation, the radio frequency circuitry and antennas may be located independently of the processor performing baseband processing. For example, in a distributed scenario, the radio frequency circuitry and antennas may be located remotely and independently of the communication equipment.
