Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, device and readable storage medium. Background Art

[0002] In a time division duplexing (TDD) system, the downlink (DL) usually occupies the main time resources, such as Figure 1 As shown in the figure, this causes an imbalance in coverage between DL and uplink (UL). Compared with the frequency division duplexing (FDD) system, the TDD system has poor uplink coverage and longer latency. The subband full duplex (SBFD) proposed by the industry can solve these problems of the TDD system. Most companies support the "subband full duplex on the network equipment side and half duplex on the terminal equipment side" solution, that is, the network equipment can send and receive simultaneously on one symbol, and the terminal equipment can only receive or send on one symbol, but not simultaneously. In this way, the uplink transmission resources available to the terminal equipment are increased, which can effectively improve the UL coverage and reduce the UL latency.

[0003] In wireless communication systems, uplink L1 / L2 control signaling, or uplink control information (UCI), is generally used to support data transmission on uplink and downlink transmission channels. In existing protocols, UCI is mainly transmitted through the physical uplink control channel (PUCCH), and the PUCCH resources used to transmit UCI can be configured by network devices. In the scenario where SBFD is introduced, network devices are also required to configure PUCCH resources to transmit UCI to ensure that data on uplink and downlink transmission channels can be transmitted normally.

[0004] Currently, in the scenario where SBFD is introduced, the configuration scheme for PUCCH resources is still being explored. Summary of the invention

[0172] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0173] In the description of the present application, the words "first", "second", etc. are only used to distinguish different objects, and do not limit the quantity and execution order, and the words "first", "second", etc. are not necessarily different. For example, the first message and the second message are only used to distinguish different information, and their order is not limited. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0174] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one (item)", "the following one (item) or more (items)" or similar expressions refer to any combination of these items, including any combination of single items (items) or plural items (items). For example, at least one item (item) of a, b, or c can mean: a, b, c; a and b; a and c; b and c; or a, b and c. Among them, a, b, c can be single or multiple.

[0175] In the description of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described in this application as "exemplary", "for example" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary", "for example" or "for example" is intended to present related concepts in a concrete way.

[0176] It can be understood that in the description of this application, "when", "if" and "if" all mean that the device will take corresponding actions under certain objective circumstances, but do not limit the time, nor do they require that the device must have a judgment action when it is implemented, nor do they mean that there are other limitations.

[0177] The term “simultaneously” in the present application may be understood as at the same time point, within a period of time, or within the same cycle, and may be understood in conjunction with the context.

[0178] Elements used in the singular herein are intended to mean "one or more" rather than "one and only one" unless specifically stated otherwise.

[0179] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0180] It can be understood that in each embodiment of the present application, "A and B correspond" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0181] It can be understood that in the embodiments of the present application, "used to indicate" and "indicate" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. When describing "a certain indication information is used to indicate A" or "indication information of A", it can include that the indication information directly indicates A or indirectly indicates A, but it does not mean that the indication information must carry A. The information indicated by a certain information is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association relationship between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be realized by means of the arrangement order of each information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each information can also be identified and uniformly indicated to reduce the indication overhead caused by indicating the same information separately. In addition, the specific indication method can also be various existing indication methods, such as but not limited to the above-mentioned indication methods and various combinations thereof. The specific details of various indication methods can refer to the prior art, and will not be repeated herein. As described above, it can be seen that, for example, when it is necessary to indicate multiple information of the same type, different indication methods may appear. In the specific implementation process, the required indication method can be selected according to specific needs. The embodiment of the present application does not limit the selected indication method. In this way, the indication method involved in the embodiment of the present application should be understood as covering various methods that can enable the party to be indicated to know the information to be indicated. The information to be indicated can be sent as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be pre-defined, for example, pre-defined according to the protocol, or it can be configured by the transmitting end device by sending configuration information to the receiving end device. Among them, the configuration information can, for example, but not limited to, include one or a combination of at least two of radio resource control signaling, MAC layer signaling and physical layer signaling.

[0182] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example: universal mobile telecommunications system (UMTS) or third generation (3G) system, long term evolution (LTE) system or fourth generation (4G) system, world-wide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) system, such as new generation wireless access technology (new radio, NR), a network integrating multiple systems, an Internet of Things system, an Internet of Vehicles system, and future communication systems, such as a 6G system.

[0183] It should be understood that the network architecture described in the embodiments of the present application is for the purpose of more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can know that with the evolution of the network architecture, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0185] The radio access network equipment can be called a network equipment, which is an access device for a terminal to access a communication system by wireless means. The radio access network equipment can be a base station (BS), an evolved NodeB (eNodeB, eNB for short), a transmission reception point (TRP), a next generation NodeB (gNB) in a fifth generation (5G) mobile communication system, a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a wireless fidelity (WiFi) system, etc.; it can also be a module or unit that completes part of the functions of a base station, for example, it can be a centralized unit (CU) or a distributed unit (DU). A base station including a CU and a DU can also be called a base station with a CU and a DU separated, such as a base station including a gNB-CU and a gNB-DU. Among them, CU can also be separated into CU control plane (CU control plane, CU-CP) and CU user plane (CU userplane, CU-CP), such as the base station includes gNB-CU-CP, gNB-CU-UP and gNB-DU. The CU here can complete the functions of the radio resource control protocol and packet data convergence layer protocol (packet data convergence protocol, PDCP) of the base station, and can also complete the function of the service data adaptation protocol (service data adaptation protocol, SDAP); DU can complete the functions of the radio link control layer and medium access control (medium access control, MAC) layer of the base station, and can also complete part of the physical layer or all of the physical layer. For the specific description of the above-mentioned protocol layers, please refer to the relevant technical specifications of the third generation partnership project (3GPP). The wireless access network device can be a macro base station (such as Figure 2a 110a), or a micro base station or an indoor station (such as Figure 2a 110b), may also be a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device.

[0186] In the embodiment of the present application, the device for realizing the function of the wireless access network device may be a wireless access network device; or it may be a device capable of supporting the wireless access network device to realize the function, such as a chip system, or a communication module, or a modem, etc., and the device may be installed in the wireless access network device. In the technical solution provided in the embodiment of the present application, the device for realizing the function of the wireless access network device is a wireless access network device, and the wireless access network device is a base station as an example to describe the technical solution provided in the embodiment of the present application. The base station may support networks with the same or different access technologies. The embodiment of the present application does not limit the specific technology and specific device form adopted by the wireless access network device.

[0187] The terminal device is a device with wireless transceiver function, which can send signals to the base station or receive signals from the base station. The terminal device can also be called a terminal, user equipment (UE), mobile station, mobile terminal, etc. The terminal device can be widely used in various scenarios, for example, device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, an airplane, a ship, a robot, a mechanical arm, a smart home device, a train detector, a gas station sensor, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0188] Base stations and terminals can be fixed or movable. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0189] The roles of the base station and the terminal can be relative, for example, Figure 2aThe helicopter or drone 120i in the figure can be configured as a mobile base station. For the terminal 120j that accesses the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between base stations. In this case, relative to 110a, 120i is also a base station. Therefore, base stations and terminals can be collectively referred to as communication devices. Figure 2a 110a and 110b in the figure may be referred to as communication devices having base station functions. Figure 2a 120a-120j in the figure can be called communication devices with terminal functions.

[0190] Base stations and terminals, base stations and base stations, and terminals and terminals can communicate through authorized spectrum, through unlicensed spectrum, or through both authorized spectrum and unlicensed spectrum. They can communicate through spectrum below 6 gigahertz (GHz), through spectrum above 6 GHz, or through both spectrum below 6 GHz and spectrum above 6 GHz at the same time.

[0191] In the embodiment of the present application, the device for realizing the function of the terminal may be a terminal; or it may be a device capable of supporting the terminal to realize the function, such as a chip system, or a communication module, or a modem, etc., which may be installed in the terminal. In the embodiment of the present application, the chip system may be composed of chips, or may include chips and other discrete devices. In the technical solution provided in the embodiment of the present application, the device for realizing the function of the terminal is a terminal, and the terminal is a UE as an example to describe the technical solution provided in the embodiment of the present application. The embodiment of the present application does not limit the specific technology and specific device form adopted by the terminal device.

[0192] In some scenarios, the UE can also be used to act as a base station. For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in vehicle-to-everything (V2X), device-to-device (D2D), or peer-to-peer (P2P).

[0193] In some scenarios, the UE can also be used as a relay node. For example, the UE can act as a relay device (relay) or an integrated access and backhaul (IAB) node to provide wireless backhaul services for terminal devices.

[0194] Optionally, the method provided in this application can be applied to V2X scenarios (such as the aforementioned Figure 2a The present invention is applicable to the scenario where 120a and 120b communicate with each other), and can also be applied to the scenario where the sidelink UE-to-network relay (Sidelink UE-to-Network Relay) and the scenario where the sidelink UE-to-UE relay (Sidelink UE-to-UE Relay) are used. Figure 2b , Figure 2b Schematic diagram of the Sidelink UE-to-Network Relay scenario provided by the embodiment of the present application. Figure 2b As shown, the Sidelink UE-to-NetworkRelay scenario includes Remote UE (remote UE) and Relay UE (relay UE), and also includes a base station; the method provided in this application can be applied to the communication between Remote UE and Relay UE. Figure 2c , Figure 2c Schematic diagram of the Sidelink UE-to-UE Relay scenario provided by the embodiment of the present application.

[0206] The above content explains the communication system architecture that can be applied to the embodiments of the present application. In order to better understand the technical solutions of the embodiments of the present application, several terms or nouns related to the present application are briefly introduced below to facilitate understanding by technical personnel in this field.

[0207] 1. Subband full duplex (SBFD)

[0208] In the subband full duplex (SBFD) scheme, a component carrier (CC) is divided into multiple subbands, and the transmission directions of different subbands can be different, so that transmission and reception can be performed simultaneously on one symbol. A typical SBFD scheme, such as Figure 4 As shown, the middle subband (such as Figure 4 Subband 1 in the figure is the uplink, and the upper and lower subbands (such as Figure 4 Subband 0 and subband 2 in the SBFD are downlink. It can be considered that in SBFD, uplink and downlink use different frequency domain resources (subbands). Under this scheme, the uplink transmission resources available to the terminal device are increased, which can effectively improve the UL coverage and reduce the UL delay. That is to say, for a component carrier, after the introduction of SBFD, its frequency resource configuration can at least include a downlink subband (DL subband) and an uplink subband (UL subband).

[0209] In order to reduce cross-link interference between downlink transmission on the DL subband and uplink transmission on the UL subband, a guard band may be defined between the DL subband and the UL subband. In the embodiment of the present application, there is no specific limitation on whether there is a guard band between the DL subband and the UL subband. Also, if the guard band exists, there is no specific limitation on whether the guard band should be explicitly defined and whether transmission can be performed on the guard band. In addition, the present application does not limit whether the DL subband and the UL subband can overlap.

[0210] In the present application, the SBFD time unit may refer to an SBFD symbol or an SBFD time slot; the non-SBFD time unit may refer to a non-SBFD symbol or a non-SBFD time slot. Among them, the SBFD symbol may be considered as a symbol configured with SBFD, and the non-SBFD symbol may be considered as a symbol not configured with SBFD; the SBFD time slot may be considered as a time slot configured with SBFD, and the non-SBFD time slot may be considered as a time slot not configured with SBFD. Specifically, the non-SBFD symbol / time slot may be an uplink symbol / time slot, a downlink symbol / time slot, or a flexible symbol / time slot. For example, for downlink transmission, the non-SBFD symbol / time slot may be a downlink symbol / time slot or a flexible symbol / time slot. For uplink transmission, the non-SBFD symbol / time slot may be an uplink symbol / time slot or a flexible symbol / time slot. Figure 4In the figure, time unit 1 associated with subband 0, subband 1 and subband 2 is an SBFD time unit; the component carrier associated with time unit 2 and time unit 3 is not divided into subbands, and the entire component carrier is used for uplink or downlink, and does not support simultaneous transmission and reception in one symbol, so time unit 2 and time unit 3 are non-SBFD time units.

[0211] Regarding the configuration of SBFD, depending on whether a timeslot contains both SBFD symbols and non-SBFD symbols, you can refer to the following two possible configuration methods:

[0212] (1) SBFD is configured at the time slot level, that is, all symbols contained in a time slot are either configured as SBFD symbols or all as non-SBFD symbols.

[0213] (2) SBFD is configured at the symbol level, that is, part of the symbols contained in a time slot can be configured as SBFD symbols, and the other part can be configured as non-SBFD symbols.

[0214] 2. Uplink control information (UCI)

[0215] In a communication system, data transmission on uplink and downlink transmission channels requires support from uplink L1 / L2 control signaling, which is also generally referred to as uplink control information (UCI). UCI generally includes the following information: (1) Hybrid automatic retransmission request acknowledgment (HARQ-ACK) of the received downlink sharing channel (DL-SCH) transport block (TB); (2) Channel state information (CSI) related to downlink channel conditions, which can be used to assist downlink scheduling, including multi-antenna and beamforming schemes, adaptive modulation and coding, time-frequency resource allocation and other processes; (3) Scheduling request (SR), which is used to indicate that a UE needs uplink resources for uplink sharing channel (UL-SCH) transmission.

[0216] 3. Physical uplink control channel (PUCCH)

[0217] At present, communication systems mainly transmit UCI through PUCCH. It should be noted that UCI is not only transmitted through PUCCH, but can also be transmitted through the physical uplink sharing channel (PUSCH). For example, for a user equipment (UE), when there is PUSCH transmission at the PUCCH transmission moment, UCI can be transmitted together with data through PUSCH instead of sending PUCCH separately. Of course, if the UE has the ability to send PUCCH and PUSCH at the same time, UCI can also be sent through PUCCH and PUSCH at the same time.

[0218] NR defines multiple PUCCH formats to transmit different UCIs. Different PUCCH formats have different durations and carrying bits. For example, see Table 1 below. Among them, the number of time domain symbols of PUCCH format 0 and format 2 is 1 or 2, which can also be called short PUCCH format. The number of time domain symbols of PUCCH format 1, format 3 and format 4 is 4-14, which can also be called long PUCCH format. Due to the larger number of symbols, the coverage performance of PUCCH in long PUCCH format is usually better than that of PUCCH in short PUCCH format.

[0219] Table 1 NR PUCCH formats

[0220]

[0221] In order to support a more flexible PUCCH architecture, the concept of PUCCH resource set is introduced in NR. A PUCCH resource set can contain at least 4 PUCCH resources, each PUCCH resource corresponds to a PUCCH format and all necessary parameters of the format, such as time domain resource information, frequency domain resource information, code domain resource information, coding information, frequency hopping information, etc. For example, in NR, the architecture of PUCCH resource and PUCCH resource set can be found in Figure 5, PUCCH resource set #0 can contain up to 32 PUCCH resources, and other PUCCH resource sets can contain up to 8 PUCCH resources. In addition, a UE supports up to 4 PUCCH resource sets, and each PUCCH resource set can carry a certain range of UCI bits. For example, PUCCH resource set #0 can carry up to 2 bits of UCI, so PUCCH resource set #0 can only contain PUCCH resources of PUCCH formats 0 and 1; for other PUCCH resource sets, the number of UCI bits carried can be greater than 2, so these PUCCH resource sets can contain PUCCH resources of other PUCCH formats except format 0 and 1. Among them, the maximum number of UCI bits carried by a PUCCH resource set can be configured by the network device (such as a base station) through signaling.

[0222] 4. PUCCH resource set and PUCCH resource selection

[0223] (1) When the UE is preparing to transmit UCI, if the UCI includes HARQ-ACK information bits, the UE can first select a PUCCH resource set according to the number of UCI bits to be transmitted, and then select a PUCCH resource in the selected PUCCH resource set. The base station can indicate which PUCCH resource in the PUCCH resource set to use by the terminal through the PUCCH resource indicator field in the downlink control information (DCI). For example, when the number of UCI bits is less than or equal to 2, the UE can select Figure 5 When the number of UCI bits is greater than 2 and less than or equal to N2, the UE can select Figure 5The selection of PUCCH resource set #1, PUCCH resource set #2 and PUCCH resource set #3 shown in the figure is no longer enumerated; after the UE selects a PUCCH resource set, if the number of PUCCH resources contained in the PUCCH resource set is not greater than 8, the UE can directly determine which PUCCH resource in the PUCCH resource set to use based on the PUCCH resource indicator field in the DCI. The relationship between the value of the field and the PUCCH resources can be referred to in Table 2 below.

[0224] Table 2

[0225]

[0226] If the number of PUCCH resources included in the PUCCH resource set is greater than 8, the UE can determine which PUCCH resource in the PUCCH resource set to use based on the PUCCH resource indicator field in the DCI and the predefined rules. The predefined rules can refer to the following formula:

[0227]

[0228] Among them, N CCE,p is the number of control channel elements (CCE) in the control resource set (CORESET) p received by the UE via the physical downlink control channel (PDCCH), n CCE,p is the index of the first CCE received by the UE via PDCCH, Δ PRI It is the value of the PUCCH resource indicator field in the DCI. Indicates rounding up. It means round down, and mod means remainder.

[0229] (2) When the UE is preparing to transmit UCI, and the information does not include HARQ-ACK information bits, for example, when the UCI includes CSI information and / or SR information, the PUCCH resource used by the UE may be semi-statically configured by a network device (such as a base station) through radio resource control (RRC) signaling. For example, the PUCCH resource may be configured in the CSI reporting configuration information or the SR configuration information sent by the base station.

[0230] First, the technical problems that the present application specifically aims to solve are analyzed and proposed. In the current TDD system, time slots are divided into downlink time slots, flexible time slots and uplink time slots, wherein downlink time slots are used for downlink transmission, flexible time slots can be used for downlink transmission, uplink transmission, protection interval (GP) or as reserved resources, and uplink time slots are used for uplink transmission. The current PUCCH configuration scheme in the TDD system is to provide only one same PUCCH resource set configuration for all time slots used for uplink transmission, that is, all time slots used for uplink transmission must use the same PUCCH resource set. After the introduction of SBFD, time slots can be classified into SBFD time slots and non-SBFD time slots. The PUCCH configuration scheme in the existing TDD system can be referred to. For all time slots used for uplink transmission, only one same PUCCH resource set configuration is provided. However, such a configuration lacks flexibility and may have the following problems:

[0231] (1) Since the uplink and downlink subbands of the SBFD time slot are closely adjacent, additional cross-link interference (CLI) will be introduced. As a result, when the SBFD time slot and the non-SBFD time slot use the same PUCCH resource set to transmit UCI, the PUCCH transmission performance on the SBFD time slot will be lower than the PUCCH transmission performance on the non-SBFD time slot, affecting the transmission of UCI.

[0232] (2) Since SBFD divides the component carrier into multiple subbands, some of which are used for uplink and some for downlink, it is possible that the frequency resources of some PUCCH resources fall outside the frequency range of the uplink subband, resulting in the inability to transmit these PUCCH resources. In other words, there may be a problem that some PUCCH resources can be transmitted in non-SBFD time slots but cannot be transmitted in SBFD time slots.

[0233] At present, in the scenario of introducing SBFD, the configuration scheme for PUCCH resources is still under exploration. Therefore, how to provide a PUCCH resource configuration scheme for the scenario of introducing SBFD is an issue to be solved urgently.

[0234] To this end, the present application proposes a communication method, an apparatus and a readable storage medium, and the network device can configure exclusive PUCCH resources for the two types of time units, SBFD time units and non-SBFD time units, respectively, which can improve the flexibility of PUCCH resource allocation and provide a basis for improving the transmission performance of PUCCH on SBFD time units. In addition, after configuring the two types of PUCCH resources separately, it is possible to allow the use of PUCCH resources across SBFD time units (symbols / time slots) and non-SBFD time units (symbols / time slots) to repeatedly transmit the same UCI, thereby improving the transmission performance of PUCCH and the success rate of UCI transmission, while also reducing the UCI transmission delay. In addition, when configuring the two types of PUCCH resources separately, the spatial relationship information (or transmission configuration indication status information) associated with the PUCCH transmission on different time unit types can be configured separately, so that the PUCCH on the SBFD time unit can be transmitted using a more suitable beam, thereby improving the transmission performance of PUCCH.

[0235] For ease of understanding, the technical solution provided by this application will be described below in conjunction with more drawings.

[0236] In this application, unless otherwise specified, the same or similar parts between various embodiments or implementations can refer to each other. In each embodiment of this application, and each implementation method / implementation method / implementation method in each embodiment, if there is no special explanation and logical conflict, the terms and / or descriptions between different embodiments and each implementation method / implementation method / implementation method in each embodiment are consistent and can be referenced to each other.

The implementation methods of this application described below do not constitute a limitation on the scope of protection of this application.

[0237] In the embodiment of the present application, the network device configures dedicated PUCCH resources for the SBFD time unit and the non-SBFD time unit respectively, which may include the following: Figure 6a-6c There are several ways in which Figure 6a-6c The communication method involved can be applied to the above Figure 2a-2d The network equipment and terminal equipment (UE) described in the above Figure 2a-2d The network devices and UEs described in the specification can be used to support and execute Figure 6a-6c The method flow steps shown in .

[0238] See also Figure 6a , Figure 6a is a flow chart of a communication method provided in an embodiment of the present application, such as Figure 6a As shown, the communication method includes but is not limited to the following steps:

[0239] S601: The network device sends a first message to the UE; the first message indicates one or more first-class PUCCH resource sets, and one or more second-class PUCCH resource sets; the one or more first-class PUCCH resource sets include one or more first-class PUCCH resources, and the one or more second-class PUCCH resource sets include one or more second-class PUCCH resources; the one or more first-class PUCCH resources are used by the terminal device to send uplink control information UCI on a sub-band full-duplex SBFD time unit, and the one or more second-class PUCCH resources are used by the terminal device to send UCI on a non-sub-band full-duplex non-SBFD time unit.

[0240] Correspondingly, the UE receives the first message sent by the network device.

[0241] S602: The network device receives a first UCI through a first PUCCH resource in one or more first-type PUCCH resources and / or a second PUCCH resource in one or more second-type PUCCH resources.

[0242] Accordingly, the UE sends the first UCI through a first PUCCH resource among the one or more first-type PUCCH resources and / or a second PUCCH resource among the one or more second-type PUCCH resources.

[0243] In the above Figure 6a In the present invention, the network device configures PUCCH resources exclusive to SBFD time units and PUCCH resources exclusive to non-SBFD time units at the granularity of PUCCH resource sets. For example, the network device configures one or more first-class PUCCH resource sets for SBFD time units and configures one or more second-class PUCCH resource sets for non-SBFD time units. Optionally, each resource set in the one or more first-class PUCCH resource sets may include part or all of the one or more first-class PUCCH resources, and each resource set in the one or more second-class PUCCH resource sets may include part or all of the one or more second-class PUCCH resources.

[0244] See also Figure 6b , Figure 6b : is a flow chart of another communication method provided in an embodiment of the present application, and the communication method includes but is not limited to the following steps:

[0245] S611: The network device sends a first message to the UE; the first message indicates one or more first-type physical uplink control channel PUCCH resources, and one or more second-type PUCCH resources; the one or more first-type PUCCH resources are used by the terminal device to send uplink control information UCI on a sub-band full-duplex SBFD time unit, and the one or more second-type PUCCH resources are used by the terminal device to send UCI on a non-sub-band full-duplex non-SBFD time unit.

[0246] Correspondingly, the UE receives the first message sent by the network device.

[0247] S612: The network device receives a first UCI through a first PUCCH resource among one or more first-type PUCCH resources and / or a second PUCCH resource among one or more second-type PUCCH resources.

[0248] Accordingly, the UE sends the first UCI through a first PUCCH resource among the one or more first-type PUCCH resources and / or a second PUCCH resource among the one or more second-type PUCCH resources.

[0249] In the above Figure 6b In the example, the network device configures PUCCH resources exclusive to SBFD time units and PUCCH resources exclusive to non-SBFD time units at the granularity of PUCCH resources. 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.

[0250] Optionally, if the network device subsequently wants to inform the UE in the form of resource sets which resources can be used in the SBFD time unit and which resources can be used in the non-SBFD time unit, two types of resource set configurations can be issued, one type of resource set in the two types of resource sets can be associated with part or all of the one or more first-type PUCCH resources, and the other type of resource set can be associated with part or all of the one or more second-type PUCCH resources. For example, the network device sends a second message to the terminal device; the first message indicates one or more first-type PUCCH resource sets, and one or more second-type PUCCH resource sets; any PUCCH resource set in the one or more first-type PUCCH resource sets includes one or more PUCCH resources in the one or more first-type PUCCH resources, and any PUCCH resource set in the one or more second-type PUCCH resource sets includes one or more PUCCH resources in the one or more second-type PUCCH resources.

[0251] See also Figure 6c , Figure 6c : is a flow chart of another communication method provided in an embodiment of the present application, and the communication method includes but is not limited to the following steps:

[0252] S621: The network device sends a first message to the UE; the first message indicates one or more first-type physical uplink control channel PUCCH resource sets, and one or more second-type PUCCH resource sets; the one or more first-type PUCCH resource sets include one or more first-type PUCCH resources, and the one or more second-type PUCCH resource sets include one or more second-type PUCCH resources; the one or more first-type PUCCH resource sets are used by the terminal device to send uplink control information UCI on a sub-band full-duplex SBFD time unit, and the one or more second-type PUCCH resource sets are used by the terminal device to send UCI on a non-sub-band full-duplex non-SBFD time unit.

[0253] Correspondingly, the UE receives the first message sent by the network device.

[0254] S622: The network device receives a first UCI through a first PUCCH resource among one or more first-type PUCCH resources and / or a second PUCCH resource among one or more second-type PUCCH resources.

[0255] Accordingly, the UE sends the first UCI through a first PUCCH resource among the one or more first-type PUCCH resources and / or a second PUCCH resource among the one or more second-type PUCCH resources.

[0256] In the above Figure 6cIn the embodiment, the network device configures PUCCH resources exclusive to SBFD time units and PUCCH resources exclusive to non-SBFD time units at the granularity of PUCCH resource sets (PUCCH resource set). Moreover, the network device can implicitly indicate the purpose of the PUCCH resources included in the PUCCH resource set by indicating the purpose of the PUCCH resource set during configuration. For example, the one or more first-class PUCCH resource sets are used by the terminal device to send uplink control information UCI on the sub-band full-duplex SBFD time unit, which can be understood as the one or more first-class PUCCH resources included in the one or more first-class PUCCH resource sets are used by the terminal device to send uplink control information UCI on the sub-band full-duplex SBFD time unit. Optionally, each resource set in the one or more first-class PUCCH resource sets may include part or all of the one or more first-class PUCCH resources, and each resource set in the one or more second-class PUCCH resource sets may include part or all of the one or more second-class PUCCH resources.

[0257] It should be noted that the network device can configure the PUCCH resources exclusive to the SBFD time unit and the PUCCH resources exclusive to the non-SBFD time unit at the granularity of the PUCCH resource set; it can also configure the PUCCH resources exclusive to the SBFD time unit and the PUCCH resources exclusive to the non-SBFD time unit at the granularity of the PUCCH resources, which is not specifically limited in this application. The network device can directly indicate the purpose of the PUCCH resources, or it can imply the purpose of the PUCCH resources included therein by indicating the purpose of the PUCCH resource set, which is not specifically limited in this application.

[0258] Optionally, in the above Figure 6a-6cIn the SBFD time unit, the SBFD time unit can be a SBFD symbol or a SBFD time slot, that is, the SBFD time unit is a symbol or time slot configured with SBFD; the non-SBFD time unit can be a non-SBFD symbol or a non-SBFD time slot, that is, the non-SBFD time unit is a symbol or time slot not configured with SBFD. It should be noted that the PUCCH resources exclusive to the SBFD time unit (such as one or more first-category PUCCH resources) can be considered as PUCCH resources transmitted on the SBFD symbol / time slot, and the PUCCH resources exclusive to the non-SBFD time unit (such as one or more second-category PUCCH resources) can be considered as PUCCH resources transmitted on the non-SBFD symbol / time slot. Among them, the non-SBFD symbol / time slot configured with PUCCH resources can be an uplink symbol / time slot, or a flexible symbol / time slot, etc.

[0259] Optionally, the first PUCCH resource for transmitting and receiving the 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 the second PUCCH resource for transmitting and receiving the 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. Further optionally, each of the one or more first-category PUCCH resources includes 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, so as to avoid the problem that the PUCCH resources cannot be sent on the SBFD time unit because the frequency resources fall outside the uplink subband range.

[0260] For ease of understanding, the following description is made based on the manner in which the network device configures PUCCH resources according to the granularity of the PUCCH resource set. For example, Figure 7 As shown, the network device can configure X PUCCH resource sets (corresponding to one or more first-type PUCCH resource sets) exclusive to the SBFD time unit, and configure Y PUCCH resource sets (corresponding to one or more second-type PUCCH resource sets) exclusive to the non-SBFD time unit, where X and Y are both positive integers. X can be greater than Y, X can be less than Y, and X can also be equal to Y. Optionally, for the two types of PUCCH resource sets, in addition to independently configuring the PUCCH resources they include, the network device can also independently configure the maximum load size of each PUCCH resource set, that is, the network device can independently configure how many bits of UCI each PUCCH resource set can carry at most.

[0261] In one possible implementation, when configuring the PUCCH resources in the PUCCH resource sets, the network device may first configure all the PUCCH resources that may be used by the network device. Exemplarily, the network device may first configure a dedicated resource ID for each of the PUCCH sources that may be used. Then, when configuring the PUCCH resource sets, the network device may associate one or more PUCCH resources in these PUCCH sources in the configuration of each PUCCH resource set, for example, configuring one or more PUCCH resources corresponding to the resource ID in each PUCCH resource set. The following is a brief description of the process of configuring PUCCH resources exclusive to SBFD time units and PUCCH resources exclusive to non-SBFD time units at the PUCCH resource set granularity, which may refer to the following method:

[0262] Method 1:

[0263] The network device configures J PUCCH resources through the first signaling, and the J PUCCH resources are resources that the network device may use, where J is a positive integer. When the network device configures X PUCCH resource sets exclusive to SBFD time units and / or Y PUCCH resource sets exclusive to non-SBFD time units, the X PUCCH resource sets exclusive to SBFD time units and / or the Y PUCCH resource sets exclusive to non-SBFD time units are associated with all or part of the J PUCCH resources.

[0264] Method 2:

[0265] The network device configures J PUCCH resources through the first signaling and K PUCCH resources through the second signaling respectively, and the J PUCCH resources and K PUCCH resources are resources that the network device may use, wherein J and K are both positive integers. When the network device configures X PUCCH resource sets exclusive to SBFD time units and Y non-PUCCH resource sets exclusive to non-SBFD time units, the PUCCH resource sets exclusive to the X SBFD time units can be associated with all or part of the PUCCH resources in the J PUCCH resources, and the PUCCH resource sets exclusive to the Y non-SBFD time units can be associated with all or part of the PUCCH resources in the K PUCCH resources.

[0266] Furthermore, for the exclusive PUCCH resources in the above two types of PUCCH resource sets, the network equipment can independently configure the parameters exclusive to each PUCCH resource, such as PUCCH format, whether to support frequency hopping within the time slot, the starting position in the frequency domain, the position of the second frequency hopping domain (when frequency hopping is supported), the number of physical resource blocks (PRB), the length and index of the time domain orthogonal cover code (OCC), the number of time domain symbols, the starting symbol, and the initial cyclic shift. Optionally, the public parameters exclusive to the PUCCH format can also be independently configured, such as whether to support frequency hopping between time slots, whether to support additional DMRS, the maximum code rate, the number of time slots for transmission, whether to support π / 2BPSK modulation, whether to support simultaneous transmission of HARQ-ACK and CSI, etc.

[0267] Optionally, when the network device configures each PUCCH resource, compared with the PUCCH resources (such as the second PUCCH resource) exclusive to the non-SBFD time unit, the network device can configure the time domain duration of the PUCCH resources (such as the first PUCCH resource) exclusive to the SBFD time unit to be longer, for example, more time slots and / or more symbols in the time slot. 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. Among them, the PUCCH resources corresponding to PUCCH format 0 / 1 / 2 / 3 / 4 can be configured in this way. A longer time domain duration means greater reception energy, or a lower reception code rate, which is beneficial to improving the transmission performance of PUCCH.

[0268] Optionally, when configuring each PUCCH resource, the network device may configure the frequency resource width of the PUCCH resources exclusive to the SBFD time unit to be wider than that of the PUCCH resources exclusive to the non-SBFD time unit, for example, a larger number of resource blocks (RBs). That is to say, the frequency resource width of the first PUCCH resource is greater than the frequency resource width of the second PUCCH resource. A wider frequency resource means greater receiving energy, or a lower receiving code rate, or a longer orthogonal sequence, which is beneficial to improving the transmission performance of the PUCCH.

[0269] Optionally, when configuring each PUCCH resource, the network device may configure a lower maximum code rate for the PUCCH resources exclusive to the SBFD time unit than for the PUCCH resources exclusive to the non-SBFD time unit. That is, the maximum code rate of the first PUCCH resource is less than the maximum code rate of the second PUCCH resource, and a lower reception code rate is conducive to improving the transmission performance of the PUCCH. Exemplarily, the network device may configure a lower maximum code rate for the PUCCH resources corresponding to PUCCH format 2 / 3 / 4.

[0270] Optionally, when configuring each PUCCH resource, the network device may configure more demodulation reference signal (DMRS) symbols for the PUCCH resources exclusive to the SBFD time unit than for the PUCCH resources exclusive to the non-SBFD time unit. That is to say, the number of DMRS symbols for the first PUCCH resource is greater than the number of DMRS symbols for the second PUCCH resource. More DMRS symbols are beneficial to improving the demodulation performance of the PUCCH, thereby improving the transmission performance of the PUCCH. Exemplarily, the network device may configure more DMRS symbols for the PUCCH resources corresponding to PUCCH format 1 / 2 / 3 / 4.

[0271] In a possible implementation, when configuring each PUCCH resource, the network device may also configure the spatial relationship information (or transmission configuration indication status information) associated with them. Optionally, the network device may independently configure the spatial relationship information (or transmission configuration indication status information) associated with the PUCCH transmission on the SBFD time unit (corresponding to the first PUCCH resource) and the PUCCH transmission on the non-SBFD time unit (corresponding to the second PUCCH resource). Exemplarily, the spatial relationship information (or transmission configuration indication status information) configured for the one or more first-category PUCCH resources and the one or more second-category PUCCH resources may be the same or different. For another example, the spatial relationship information (or transmission configuration indication status information) configured between each resource in the one or more first-category PUCCH resources may be the same or different; the spatial relationship information (or transmission configuration indication status information) configured between each resource in the one or more second-category PUCCH resources may be the same or different. In an embodiment of the present application, the network device can enable the PUCCH on the SBFD time unit to be transmitted using a more suitable beam (for example, one with less CLI interference) by independently configuring the spatial relationship information associated with the PUCCH transmission on the SBFD time unit and the PUCCH transmission on the non-SBFD time unit, thereby reducing or avoiding the impact of the CLI on the PUCCH transmission and improving the PUCCH transmission performance on the SBFD time unit.

[0272] Optionally, the spatial relationship information (or transmission configuration indication state information) may include a reference signal 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 indication state information) may also include a power control parameter of the PUCCH, such as an open-loop parameter Po, a closed-loop parameter closed-loop process index.

[0273] As for how to configure or activate the spatial relationship information of PUCCH, the following examples can be referred to:

[0274] (1) For scenarios where the network device can explicitly configure spatial setting information, the following two possible activation methods can be used to determine whether PUCCH resources are configured separately on two types of time units (symbols / time slots):

[0275] 1) For scenarios where exclusive PUCCH resources are configured on two types of time units (symbols / time slots) respectively, SBFD and non-SBFD, the network device can indicate the spatial relationship information of PUCCH resources transmitted on different types of time units through a medium access control-control element (MAC-CE). For example, the network device sends a third message to indicate the reference signal associated with the first PUCCH resource and the reference signal associated with the second PUCCH resource. The network device can also indicate the spatial relationship information of PUCCH resources transmitted on different types of time units through different MAC-CEs. For example, the network device sends a third message and a fourth message, 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.

[0276] 2) For the scenario where different PUCCH resources are not configured on the two time units (symbols / time slots) of SBFD and non-SBFD, that is, the network device does not configure exclusive PUCCH resources for SBFD time units and non-SBFD time units respectively, and the same PUCCH resource set resources are used on these two types of time units. The network device can indicate two spatial relationship information for one PUCCH resource through a MAC CE, which are used for the transmission of the PUCCH resource on the above two different types of time units (symbols / time slots).

[0277] (2) For scenarios where network devices do not explicitly configure spatial setting, regardless of whether dedicated PUCCH resources are configured on SBFD and non-SBFD time units (symbols / time slots), the spatial setting information of PUCCH transmissions on these two different types of time units (symbols / time slots) is the same as that of PDCCH transmissions on the same type of time units (symbols / time slots). Figure 8As shown, the spatial relationship information between the PUCCH on the SBFD time slot and the PDCCH on the SBFD time slot is the same, and the spatial relationship information between the PUCCH on the non-SBFD time slot and the PDCCH on the non-SBFD time slot is the same. For example, the reference signal associated with the first PUCCH resource is the same as the reference signal associated with the first physical downlink control channel PDCCH received by the terminal device on the SBFD time unit; wherein the first PDCCH is received by the terminal device in the control resource set CORESET with the lowest index value on the activated downlink partial bandwidth BWP corresponding to the SBFD time unit; the reference signal associated with the second PUCCH resource is the same as the reference signal associated with the second PDCCH received by the terminal device on the non-SBFD time unit; wherein the second PDCCH is received by the terminal device in the CORESET with the lowest index value on the activated downlink BWP corresponding to the non-SBFD time unit.

[0278] Optionally, the first message used by the network device to send the PUCCH resources exclusive to the SBFD time unit and the PUCCH resources exclusive to the non-SBFD time unit to the UE may be RRC signaling or system information block 1 (SIB1) signaling, etc. It should be noted that the network device may send the above two types of time unit exclusive PUCCH resource configurations to the UE together through one signaling, or may complete the sending of the two types of time unit exclusive PUCCH resource configurations in multiple times through multiple signalings, which is not specifically limited here.

[0279] After the network device sends the PUCCH resources exclusive to the above two types of time units to the terminal device (corresponding to the above steps S601, S611 or S621), it can subsequently receive the UCI uploaded by the terminal device through these PUCCH resources, that is, through the first PUCCH resource among the one or more first-type PUCCH resources, and / or, the second PUCCH resource of the one or more second-type PUCCH resources to receive the first UCI sent by the terminal device (corresponding to the above steps S602, S612 or S622).

[0280] In one possible implementation, after receiving the one or more first-category PUCCH resource sets and the one or more second-category PUCCH resource sets (or the one or more first-category PUCCH resources and the one or more second-category PUCCH resources), for the UCI to be transmitted (corresponding to the first UCI), the UE can repeatedly transmit the UCI across SBFD time units and non-SBFD time units.

[0281] Optionally, the UE may repeatedly transmit the first UCI N times on the first PUCCH resource corresponding to the SBFD time unit, and repeatedly transmit the first UCI M times on the second PUCCH resource corresponding to the non-SBFD time unit; the first PUCCH resource belongs to one or more first-category PUCCH resources, the second PUCCH resource belongs to one or more second-category PUCCH resources, and M and N are both integers greater than 0. Accordingly, the network device receives the above-mentioned first UCI repeatedly transmitted by the UE on the PUCCH resources (including the first PUCCH resource and the second PUCCH resource) corresponding to different time units. In an embodiment of the present application, for the same UCI information, the UE uses different PUCCH resources for repeated transmission in two types of time units, which can improve the transmission performance of the PUCCH, improve the UCI transmission success rate, and also reduce the UCI transmission delay.

[0282] For example, the UE may first determine the PUCCH resource (corresponding to the first PUCCH resource) used to transmit the first UCI in the SBFD time unit, and the PUCCH resource (corresponding to the second PUCCH resource) used to transmit the first UCI information in the non-SBFD time unit. Then, the UE repeatedly transmits the first UCI in the SBFD time unit and the non-SBFD time unit according to the determined one or more PUCCH resource(s). For example, Fig. 9 As shown, the UE may determine to use PUCCH resource #X on the SBFD time unit (symbol / time slot), and to use PUCCH resource #Y on the non-SBFD time unit (symbol / time slot), and associate the PUCCH resource #X with the PUCCH resource #Y. Further, for M+N repeated transmissions, the UE may use PUCCH resource #X to repeatedly transmit the first UCI information N times, and use PUCCH resource #Y to repeatedly transmit the first UCI information M times.

[0283] Exemplarily, the SBFD time unit may include SBFD time slot 1, SBFD time slot 2, ..., SBFD time slot N, and the non-SBFD time unit may include non-SBFD time slot 1, non-SBFD time slot 2, ..., non-SBFD time slot M. For M+N repeated transmissions, the UE may use PUCCH resource #X to transmit UCI once on SBFD time slot 1, SBFD time slot 2, ..., SBFD time slot N, and use PUCCH resource #Y to transmit UCI once on non-SBFD time slot 1, non-SBFD time slot 2, ..., non-SBFD time slot M. Understandably, the UE may also transmit UCI on multiple SBFD symbols and non-SBFD symbols, respectively, which will not be expanded here.

[0284] It should be noted that the UE may repeatedly transmit the UCI across SBFD time units and non-SBFD time units, or may transmit the UCI only on the SBFD time unit, or may transmit the UCI only on the non-SBFD time unit. For example, the UE sends the first UCI through the first PUCCH resource in the one or more first-category PUCCH resources, or the second PUCCH resource in the one or more second-category PUCCH resource set. Accordingly, the network device receives the first UCI sent by the terminal device through the first PUCCH resource in the one or more first-category PUCCH resources, or the second PUCCH resource in the one or more second-category PUCCH resources.

[0285] Regarding how the UE determines the PUCCH resources used to transmit UCI in the SBFD time unit and the non-SBFD time unit, the following methods can be referred to:

[0286] (1) When UCI information includes HARQ-ACK information

[0287] In a possible implementation, the network device sends DCI, which includes an indication field (corresponding to the first PUCCH resource indication field), and the UE can determine the PUCCH resource used in the SBFD time unit and the non-SBFD time unit respectively according to an indication field in the DCI sent by the network device.

[0288] In a possible implementation, the network device sends a DCI, which includes two indication fields (corresponding to the first PUCCH resource indication field and the second PUCCH resource indication field), and the UE can determine the PUCCH resource used in the SBFD time unit and the non-SBFD time unit respectively according to the two indication fields in the DCI sent by the network device. Exemplarily, one of the two indication fields of the DCI can reuse the existing PUCCH resource indicator field, and the other indication field can be a newly introduced indication field, for example, referred to as the Second PUCCH resource indicator field. Among them, the former is associated with the non-SBFD time unit and is used to indicate the PUCCH resource used in the non-SBFD time unit, and the latter (i.e., the newly introduced indication field) is associated with the SBFD time unit and is used to indicate the PUCCH resource used in the SBFD time unit.

[0289] Optionally, before the UE determines the PUCCH resources to be used according to the indication field carried by the DCI, it may first determine the PUCCH resource set(s) to be used according to the number of bits of the UCI information to be transmitted. When the network device is not configured with two types of exclusive PUCCH resource sets, the method for the UE to determine the PUCCH resource set can refer to the prior art and will not be repeated here. When the network device is configured with two types of exclusive PUCCH resource sets, that is, the network device is configured with one or more first-type PUCCH resource sets, and, the one or more second-type PUCCH resource sets, the UE determines the PUCCH resource set used on the SBFD time unit, and, the PUCCHresource set used on the non-SBFD time unit. In a possible implementation, the UE determines a PUCCHresource set in the one or more first-type PUCCHresource sets, and, determines a PUCCHresource set in the one or more second-type PUCCHresource sets, according to the number of bits of the UCI information to be transmitted. Then, the UE determines which specific PUCCH resource in the corresponding PUCCH resource set to use according to the indication field in the DCI. Regarding how the UE determines the corresponding PUCCH resource set according to the number of UCI bits and determines the specific PUCCH resource according to the indication field in the DCI, please refer to the relevant description in the previous "PUCCH resource set and PUCCH resource selection", which will not be repeated here.

[0290] It should be noted that the above method can be applicable to a physical downlink shared channel (PDSCH) dynamic scheduling scenario, and can also be applicable to a PDSCH semi-persistent scheduling scenario.

[0291] (2) When the UCI information does not include HARQ-ACK information but includes CSI information and / or SR information

[0292] For this scenario, the network device can configure the PUCCH resource used by the UE to transmit UCI on the SBFD time unit and the non-SBFD time unit respectively through RRC signaling. That is, the network device can send a seventh message; the seventh message indicates the first PUCCH resource and the second PUCCH resource, and the seventh message is used to instruct the terminal device to use the first PUCCH resource and the second PUCCH resource to transmit the first UCI. Exemplarily, when the UCI information to be transmitted is a CSI report or SR, the network device can include the PUCCH resources used to transmit UCI on the SBFD time unit and the non-SBFD time unit respectively in the configuration information of the CSI report or the SR configuration information. Optionally, the above-mentioned seventh message can be a radio resource control RRC signaling, a system information block SIB or a MAC CE, which is not specifically limited here.

[0293] It should be noted that after the introduction of SBFD, the network equipment can configure exclusive PUCCH resources for SBFD and non-SBFD time units respectively; it can also not configure exclusive PUCCH resources for SBFD time units and non-SBFD time units respectively, and use the same PUCCH resources on these two types of time units.

[0294] In a possible implementation, when the network device does not configure dedicated PUCCH resources for SBFD and non-SBFD time units respectively, the UE can repeatedly transmit UCI in the SBFD time unit and the non-SBFD time unit respectively through the same PUCCH resource. Accordingly, the network device can receive the UCI repeatedly transmitted by the UE in different time units through the same PUCCH resource.

[0295] See also Fig.10 , Fig.10 : is a flow chart of another communication method provided in an embodiment of the present application, and the communication method includes but is not limited to the following steps:

[0296] S701: The network device sends a fifth message to the UE; the fifth message indicates one or more PUCCH resources, and the one or more PUCCH resources are used by the terminal device to send UCI in SBFD time units and non-SBFD time units.

[0297] S702: The network device receives the second UCI repeatedly transmitted by the terminal device N times through the third PUCCH resource in the SBFD time unit; and receives the second UCI repeatedly transmitted by the terminal device M times through the third PUCCH resource in the non-SBFD time unit; wherein the third PUCCH resource belongs to the one or more PUCCH resources, and M and N are both integers greater than 0; the spatial relationship applied each time the third PUCCH resource repeatedly transmits the second UCI N times in the SBFD time unit is the same; the spatial relationship applied each time the third PUCCH resource repeatedly transmits the second UCI M times in the non-SBFD time unit is the same.

[0298] Optionally, the network device may indicate two spatial relationship information for a PUCCH resource through a MAC CE, which are respectively used for the transmission of the PUCCH resource in the above two different types of time units (symbols / time slots). For example, the network device sends a sixth message, and the sixth message is used to indicate the spatial relationship corresponding to the third PUCCH resource in the SBFD time unit, and the spatial relationship corresponding to the third PUCCH resource in the non-SBFD time unit. The network device can configure the same spatial relationship for the same PUCCH resource in different time units, or it can configure different spatial relationships, which is not specifically limited here.

[0299] Optionally, in the above step S701, the network device is configured at the granularity of PUCCH resources. If the network device subsequently needs to inform the UE which resources can be used in the SBFD time unit and the non-SBFD time unit in the form of a resource set, the resource set configuration can be issued, and this resource set can be associated with part or all of the one or more first PUCCH resources. It should be noted that the network device can also be configured at the granularity of the PUCCH resource set, which is not specifically limited here, and the specific configuration can also be referred to Figure 6a and Figure 6c The relevant description in will not be expanded here.

[0300] It should be noted that the UE can use the same PUCCH resource to repeatedly transmit UCI across SBFD time units and non-SBFD time units, or can transmit UCI only on SBFD time units, or can transmit UCI only on non-SBFD time units. For example, the UE sends the second UCI through the third PUCCH resource on the SBFD time unit, or sends the second UCI through the third PUCCH resource on the non-SBFD time unit. Accordingly, the network device receives the second UCI sent by the terminal device through the third PUCCH resource on the SBFD time unit, or through the third PUCCH resource on the non-SBFD time unit.

[0301] In summary, in the above embodiments, the network device can configure exclusive PUCCH resources for the two types of time units, SBFD time units and non-SBFD time units, respectively, which can improve the flexibility of PUCCH resource allocation and provide a basis for improving the transmission performance of PUCCH on SBFD time units. In addition, after configuring the two types of PUCCH resources separately, it can be allowed to use PUCCH resources across SBFD time units (symbols / time slots) and non-SBFD time units (symbols / time slots) to repeatedly transmit the same UCI, thereby improving the transmission performance of PUCCH and the success rate of UCI transmission, while also reducing the UCI transmission delay. In addition, when configuring the two types of PUCCH resources separately, the spatial relationship information (or transmission configuration indication status information) associated with the PUCCH transmission on different time unit types can be configured separately, so that the PUCCH on the SBFD time unit can be transmitted using a more suitable beam, thereby improving the transmission performance of PUCCH.

The above integrated modules can be implemented in the form of hardware or in the form of software functional modules.

[0371] It is understandable that the specific description of the receiving unit, the sending unit and the processing unit shown in the above device embodiment is only an example. For the specific functions or execution steps of the receiving unit, the sending unit and the processing unit, etc., reference can be made to the above Figure 6a-6c or Fig.10 The description of any method embodiment in will not be described in detail here.

[0372] The above describes the communication device of the embodiment of the present application, and the following describes possible product forms of the communication device. It should be understood that any device having the above Fig.11 Any form of product with the functions of the communication device described above falls within the protection scope of the embodiments of the present application. It should also be understood that the following description is only an example and does not limit the product form of the communication device of the embodiments of the present application to this.

[0373] In a possible implementation, the above Fig.11 In the communication device shown, the processing unit 102 ( Fig.11 (not shown) may be one or more processors; the sending unit 100 and the receiving unit 101 may be transceivers; or, the sending unit 100 may be a transmitter and the receiving unit 101 may be a receiver. In the embodiment of the present application, the processor and the transceiver may be coupled, etc., and the embodiment of the present application does not limit the connection method between the processor and the transceiver. In the process of executing the above method, the process of sending information in the above method can be understood as the process of the processor outputting the above information. When outputting the above information, the processor outputs the above information to the transceiver so that it is transmitted by the transceiver. After the above information is output by the processor, it may also need to be processed in other ways before it reaches the transceiver. Similarly, the process of receiving information in the above method can be understood as the process of the processor receiving the input information. When the processor receives the input information, the transceiver receives the above information and inputs it into the processor. Furthermore, after the transceiver receives the above information, the above information may need to be processed in other ways before it is input into the processor.

The communication device 20 may be the communication device 10, or a chip therein. Fig.12 Only the main components of the communication device 20 are shown.

The memory 1003 is mainly used to store the software program and data. The transceiver 1002 may include a control circuit and an antenna. The control circuit is mainly used to convert the baseband signal and the radio frequency signal and process the radio frequency signal. The antenna is mainly used to send and receive radio frequency signals in the form of electromagnetic waves. The input and output devices, such as a touch screen, a display screen, a keyboard, etc., are mainly used to receive data input by the user and output data to the user.

[0376] When the communication device is turned 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 sent wirelessly, the processor 1001 performs baseband processing on the data to be sent, and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then sends the radio frequency signal outward in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 1001. The processor 1001 converts the baseband signal into data and processes the data.

[0377] In another implementation, the RF circuit and antenna may be arranged independently of the processor performing baseband processing. For example, in a distributed scenario, the RF circuit and antenna may be arranged remotely from the communication device.
