Description

Method and device for reporting capabilities

[0001] This application claims priority to the Chinese patent application with application number 202410204952.9 filed with the State Intellectual Property Office of China on February 23, 2024, and priority to the Chinese patent application with the invention name “Method and Device for Capability Reporting”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more specifically, to a method and apparatus for capability reporting. Background Art

[0003] With the rapid development of fifth-generation mobile communication technology, new radio (NR), a diverse range of communication needs have emerged. To meet the demands of these emerging services, a subband non-overlapping full duplex (SBFD) solution has been proposed to improve the uplink coverage of time division duplex (TDD) systems. Subband full duplex, in a TDD system, enables network devices to both receive and transmit within a single time slot or orthogonal frequency division multiplexing (OFDM) symbol, using different subbands for uplink and downlink transmissions.

[0004] Currently, in SBFD timeslots, SBFD-capable terminal devices do not expect to perform uplink transmissions outside of the uplink subband and do not expect to perform downlink transmissions on the uplink subband. When an SBFD-capable terminal device transmits uplink signals on the uplink subband, signal sidelobe energy may leak into the downlink subband, interfering with the terminal device's reception of downlink signals. Furthermore, if an SBFD-capable terminal device is performing uplink transmissions on the uplink subband and a legacy terminal device (e.g., one that only supports TDD) is adjacent to the SBFD-capable terminal device and the legacy terminal device is currently receiving downlink signals, the SBFD-capable terminal device may interfere with the legacy terminal's reception of downlink signals.

[0005] In addition, if the full bandwidth or partial bandwidth (BWP) is used for uplink transmission in the current TDD working mode on the uplink sub-band of the terminal device supporting SBFD, the sampling rate will increase, thereby increasing the power consumption of the terminal device and reducing the energy efficiency of the terminal device.

[0006] Therefore, how to reduce the transmission interference and power consumption of terminal devices supporting SBFD is an urgent problem to be solved. Summary of the Invention

[0007] The present application provides a capability reporting method and apparatus, which can reduce transmission interference of terminal devices supporting SBFD.

[0008] In a first aspect, a method for capability reporting is provided, the method comprising: sending capability information to a network device, the capability information indicating at least one of the following: a first uplink transmission capability of the terminal device supporting full bandwidth; a second uplink transmission capability of the terminal device supporting uplink sub-band; a third uplink transmission capability of the terminal device supporting uplink sub-band and full bandwidth; a fourth uplink transmission capability of the terminal device supporting sub-band full-duplex SBFD with interval switching; or a fifth uplink transmission capability of the terminal device supporting SBFD without interval switching.

[0009] Among them, the first uplink transmission capability indicates that the terminal device has the ability to perform uplink transmission at the full bandwidth. The second uplink transmission capability indicates that the terminal device has the ability to perform uplink transmission on the uplink sub-band. The third uplink transmission capability is that the terminal device has both the first uplink transmission capability and the second uplink transmission capability, but the terminal device performs uplink transmission through one of the first uplink transmission capability or the second uplink transmission capability. The fourth uplink transmission capability indicates that the terminal device supports the first uplink transmission capability and the second uplink transmission capability at the same time, and realizes switching between the full bandwidth and the uplink sub-band through the first interval duration during the uplink transmission process. And / or, the fourth uplink transmission capability indicates that the terminal device supports the first uplink transmission capability and the second uplink transmission capability at the same time, and realizes switching between different uplink sub-bands through the second interval duration during the uplink transmission process. The fifth uplink transmission capability is that the terminal device supports the first uplink transmission capability and the second uplink transmission capability at the same time, and during the uplink transmission process, there is no need to switch between the full bandwidth and the uplink sub-band through the first interval duration; and / or, the fifth uplink transmission capability is that the terminal device does not need to switch between different uplink sub-bands through the second interval duration during the uplink transmission process.

[0010] In the above technical solution, the terminal device reports its specific uplink transmission capabilities for SBFD to the network device, which helps the terminal device subsequently use different transmission bandwidths for uplink transmission based on the specific uplink transmission capabilities on the resources scheduled by the network device. Compared to the solution of using the full bandwidth as the transmission bandwidth to ensure compatibility with SBFD uplink sub-band and full-bandwidth uplink transmission, the solution of the embodiment of the present application can reduce the interference of uplink transmission on downlink transmission, improve the energy efficiency of the terminal device, reduce the energy consumption of the terminal device, and thus improve system performance.

[0011] In combination with the first aspect, in some implementations of the first aspect, the capability information includes first capability information, and the first capability information is used to indicate any one of the first uplink transmission capability, the second uplink transmission capability, the third uplink transmission capability, the fourth uplink transmission capability or the fifth uplink transmission capability.

[0012] In combination with the first aspect, in some implementations of the first aspect, the capability information further includes second capability information, where the second capability information is used to indicate capabilities other than the capabilities indicated by the first capability information.

[0013] In this way, the basic capabilities of the terminal device are reported to the network device through the first capability information. When the terminal device has other additional capabilities, it is reported to the network device through the second capability information. The additional capabilities can be used as enhanced capabilities, which can not only reduce the interference of uplink transmission on downlink transmission, but also improve the energy efficiency of the terminal device, reduce the energy consumption of the terminal device, and thus improve the system performance. It can also be compatible with the current capability reporting method.

[0014] In conjunction with the first aspect, in certain implementations of the first aspect, when the capability information is used to indicate the fourth uplink transmission capability, the method further includes: sending indication information of a first interval duration, and / or sending indication information of a second interval duration. The first interval duration is used for switching between an uplink subband and full bandwidth, and the second interval duration is used for switching between different uplink subbands.

[0015] In this way, the terminal device reports the interval duration for switching between the uplink sub-band and full bandwidth and / or the interval duration for switching between uplink sub-bands to the network device, which helps to subsequently improve the synchronization of uplink transmission between the terminal device and the network device, thereby improving transmission performance.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the method also includes: receiving first indication information from a network device, the first indication information indicating one of the following: the network device configures a first uplink transmission capability for the terminal device; the network device configures a second uplink transmission capability for the terminal device; the network device configures a fourth uplink transmission capability for the terminal device; or the network device configures a fifth uplink transmission capability for the terminal device.

[0017] In this way, the terminal device receives the uplink transmission capability configured by the network device, which helps the terminal device to subsequently use different transmission bandwidths for uplink transmission on the resources scheduled by the network device according to the specific uplink transmission capability, thereby reducing the interference of uplink transmission on downlink transmission, improving the energy efficiency of the terminal device, reducing the energy consumption of the terminal device, and thus improving system performance.

[0018] In combination with the first aspect, in some implementations of the first aspect, the method further includes sending an uplink signal to the network device based on the capability information.

[0019] In this way, if the network device does not send the first indication information to the terminal device, the terminal device can send an uplink signal to the network device based on the capability information, which can further save signaling overhead.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: when the first indication information instructs the network device to configure a fourth uplink transmission capability for the terminal device, receiving second indication information from the network device. When the first interval duration and / or the second interval duration is insufficient or the terminal device does not detect the reserved first interval duration and / or the second interval duration in the resource information, not performing uplink transmission at the location of the time-frequency resource indicated by the second indication information.

[0021] In this way, when the first interval duration and / or the second interval duration is insufficient or the terminal device does not detect the reserved first interval duration and / or the second interval duration in the resource information, the terminal device may not perform uplink transmission at the time-frequency resource position indicated by the second indication information, and may switch between the uplink sub-band and the full bandwidth, or switch between different uplink sub-bands. This approach can cope with situations where scheduling resources are insufficient or conflicting, thereby ensuring uplink transmission performance and improving the energy efficiency of the terminal device.

[0022] In combination with the first aspect, in certain implementations of the first aspect, the method also includes: when the first indication information instructs the network device to configure a fourth uplink transmission capability for the terminal device, and when the first interval duration and / or the second interval duration is insufficient or the terminal device does not detect the reserved first interval duration and / or the second interval duration in the resource information, no uplink transmission is performed at the location of the time-frequency resources indicated by the pre-configured second indication information.

[0023] In this way, the second indication information is pre-configured in the terminal device, which can further save the signaling overhead between the network device and the terminal device.

[0024] In combination with the first aspect, in certain implementations of the first aspect, the second indication information is used to indicate the time-frequency resource location of the terminal device that does not perform uplink transmission when switching between the uplink sub-band and the full bandwidth, and / or, the second indication information is used to indicate the time-frequency resource location of the terminal device that does not perform uplink transmission when switching between different uplink sub-bands.

[0025] In conjunction with the first aspect, in certain implementations of the first aspect, the method further includes: receiving resource information scheduled from a network device, and sending an uplink signal to the network device based on the first indication information, the resource information, and the capability information.

[0026] In combination with the first aspect, in certain implementations of the first aspect, sending an uplink signal to a network device based on the first indication information, resource information and capability information includes: when the capability indicated by the first indication information and the capability indicated by the capability information are consistent, using the transmission bandwidth to send an uplink signal to the network device based on the capability indicated by the first indication information, the transmission bandwidth includes the working bandwidth corresponding to the resource information, or the transmission bandwidth includes the working bandwidth determined based on the working bandwidth corresponding to the resource information and the resources of the valid resource block.

[0027] In this way, when the capability indicated by the capability information is consistent with the capability indicated by the first indication information, the terminal device uses different transmission bandwidths for uplink transmission on the resources scheduled by the network device according to the specific uplink transmission capability, which can reduce the interference of uplink transmission on downlink transmission, improve the energy efficiency of the terminal device, reduce the energy consumption of the terminal device, and thus improve the system performance.

[0028] In conjunction with the first aspect, in certain implementations of the first aspect, sending an uplink signal to the network device based on the first indication information, the resource information, and the capability information includes: when the capability indicated by the first indication information is lower than the capability indicated by the capability information, sending the uplink signal to the network device based on the capability indicated by the first indication information. Alternatively, when the capability indicated by the first indication information is higher than the capability indicated by the capability information, sending the uplink signal to the network device based on the capability indicated by the capability information.

[0029] In this way, when the capability indicated by the capability information is inconsistent with the capability indicated by the first indication information, the terminal device can use different transmission bandwidths for uplink transmission based on a more reasonable uplink transmission capability, which can reduce the interference of uplink transmission on downlink transmission, improve the energy efficiency of the terminal device, reduce the energy consumption of the terminal device, and thus improve the system performance.

[0030] In combination with the first aspect, in some implementations of the first aspect, the method further includes: sending auxiliary information to the network device, the auxiliary information being used to indicate one of the following: a first uplink transmission capability, a second uplink transmission capability, a fourth uplink transmission capability, or a fifth uplink transmission capability.

[0031] In this way, the terminal device can indicate the uplink transmission capability that it expects to update to the network device through the auxiliary information, thereby further making the uplink transmission method of the terminal device more in line with the actual needs of the terminal device.

[0032] In combination with the first aspect, in certain implementations of the first aspect, the auxiliary information includes first information and second information, or the auxiliary information includes first information; wherein the first information is used to indicate a change in the current uplink transmission capability of the terminal device, and the second information indicates capabilities other than the capabilities indicated by the first capability information.

[0033] In this way, if the terminal device only reports the first information, the network device can learn that the capability corresponding to the uplink transmission method that the terminal device wishes to update is consistent with the first capability information, which can further reduce signaling overhead.

[0034] In combination with the first aspect, in certain implementations of the first aspect, the method also includes: receiving third indication information from the network device, the third indication information indicating one of the following: the network device configures a first uplink transmission capability for the terminal device; the network device configures a second uplink transmission capability for the terminal device; the network device configures a fourth uplink transmission capability for the terminal device; or, the network device configures a fifth uplink transmission capability for the terminal device.

[0097] To facilitate understanding of the embodiments of the present application, the following points are explained:

[0098] First, in this application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments based on their internal logical relationships.

[0099] Second, in this application, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In the text description of this application, the character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Wherein a, b and c can be single or multiple, respectively.

[0100] Third, in this application, the terms "first," "second," and various numerical references (e.g., #1, #2, etc.) are used to distinguish between different components for ease of description and are not intended to limit the scope of the embodiments of this application. For example, they are used to distinguish between different uplink transmission capabilities, rather than to describe a specific order or precedence. It should be understood that the terms described in this manner are interchangeable where appropriate to describe solutions beyond the embodiments of this application.

[0101] Fourth, in this application, expressions such as "when," "under the circumstances of," and "if" all imply that a corresponding action will be taken under certain objective circumstances. They do not limit the timeframe, do not require a judgment action to be taken when the action is taken, and do not imply any other limitations. Furthermore, the judgment action following these conditional conjunctions does not imply that the judgment action following the conditional conjunctions is the only condition for achieving the result; additional conditions may also be included to achieve the result.

[0102] Fifth, in this application, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or are inherent to these processes, methods, products or apparatuses.

[0103] Sixth, in this application, "used to indicate" can include being used for direct indication and being used for indirect indication. When describing that a certain indication information is used to indicate A, it can include that the indication information directly indicates A or indirectly indicates A, and it does not mean that the indication information must carry A.

[0104] The indication methods involved in the embodiments of this application should be understood to encompass various methods that enable the party to be indicated to obtain information to be indicated. The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately. The transmission period and / or timing of these sub-information can be the same or different. This application does not limit the specific transmission method.

[0105] In the embodiments of the present application, "indication information" may be an explicit indication, i.e., a direct indication via signaling, or may be obtained based on parameters indicated by signaling, in combination with other rules, other parameters, or by deduction. It may also be an implicit indication, i.e., based on a rule or relationship, or based on other parameters, or by deduction. This application does not impose specific limitations on this.

[0106] Seventh, in this application, "protocol" may refer to a standard protocol in the field of communications, such as a 5G protocol, a new radio (NR) protocol, and related protocols used in future communication systems, and this application does not limit this. "Predefined" may include pre-definition. For example, protocol definition. "Preconfiguration" can be implemented by pre-saving corresponding codes, tables, or other methods that can be used to indicate relevant information in the device, and this application does not limit its specific implementation method.

[0107] Eighth, in this application, "storage" may refer to storage in one or more memories. The one or more memories may be provided separately or integrated into an encoder or decoder, a processor, or a device for reporting capabilities. The one or more memories may also be provided in part separately and in part integrated into a decoder, a processor, or a device for reporting capabilities. The type of memory may be any form of storage medium and is not limited in this application.

[0108] The technical solution in this application will be described below with reference to the accompanying drawings.

[0109] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example, fifth generation (5G), new radio (NR), long term evolution (LTE), Internet of Things (IoT), wireless fidelity (WiFi), wireless communications related to the 3rd Generation Partnership Project (3GPP), or other wireless communications that may appear in the future.

[0110] Figure 1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application. The communication system includes a core network device 110, a network device 120 and at least one terminal device (such as terminal device 131 and terminal device 132 in Figure 1). The terminal device is connected to the network device wirelessly, and the network device is connected to the core network device wirelessly or wired. The core network device and the network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the network device can be integrated on the same physical device, or the functions of some core network devices and some network devices can be integrated on one physical device. The terminal device can be fixed or movable. Figure 1 is only a schematic diagram, and the communication system can also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1. The embodiments of the present application do not limit the number of core network devices, wireless access network devices and terminal devices included in the communication system.

[0111] A network device is a network-side device with wireless transceiver capabilities. A network device can be a device in a radio access network (RAN) that provides wireless communication capabilities for terminal devices. It is also known as a RAN device, RAN node, RAN entity, or access node.

[0112] Exemplarily, in some possible scenarios, the network device may be a base station, an evolved NodeB (eNodeB), a next generation NodeB (gNB) in a 5G mobile communication system, a base station subsequently evolved by 3GPP, a transmission reception point (TRP), an access node in a WiFi system, a wireless relay node, a wireless backhaul node, an open access network (open RAN, O-RAN or ORAN) or a cloud radio access network (CRAN), etc. In communication systems using different radio access technologies (RAT), the names of devices with base station functions may be different. For example, in an LTE system, it may be called an eNB or eNodeB, and in a 5G system or an NR system, it may be called a gNB. This application does not limit the specific name of the base station. The network device may include one or more co-sited or non-co-sited transmission and reception points. The network device may also be a logical node, a logical module or software that implements all or part of the network device functions.

[0113] For example, in some possible scenarios, multiple network devices collaborate to assist terminal devices in achieving wireless access, and different network devices respectively implement the functions of some network devices. The network device may include one or more centralized units (CU), one or more distributed units (DU), or one or more CUs and one or more DUs. For example, the functions of the CU can be implemented by one entity or different entities. For example, the functions of the CU are further divided, that is, the control plane and the user plane are separated and implemented by different entities, namely the CU-control plane (CP) entity (i.e., CU-CP entity) and the CU-user plane (UP) entity (i.e., CU-UP entity). The CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the functions of the access network device. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. The CU and DU can be set separately, or they can be included in the same network element, such as the baseband unit (BBU). The network device can also include a radio unit (RU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0114] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0115] Terminal devices may also be referred to as terminals, user equipment (UE), mobile stations (MS), or mobile terminals (MT). Terminal devices may include mobile phones, tablet computers, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals used in industrial control, wireless terminals used in self-driving vehicles, wireless terminals used in remote medical surgery, wireless terminals used in smart grids, wireless terminals used in transportation safety, wireless terminals used in smart cities, and wireless terminals used in smart homes.

[0116] The multiple network devices in the communication system can be base stations of the same type or different types. The base station can communicate with the terminal device or communicate with the terminal device through a relay station. In the embodiment of the present application, the device for implementing the function of the network device can be the network device itself, or it can be a device that can support the network device to implement the function, such as a chip system or a combination device or component that can implement the function of the access network device, which can be installed in the network device. In the embodiment of the present application, the chip system can be composed of chips, or it can include chips and other discrete devices.

[0117] The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water; and can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the network equipment and terminal equipment.

[0118] The embodiments of the present application can be applied to downlink signal transmission, uplink signal transmission, and device-to-device (D2D) signal transmission. For downlink signal transmission, the transmitting device is a network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is a network device. For D2D signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is also a terminal device. The transmission direction of the signal in the embodiments of the present application is not limited.

[0119] It should be understood that in this application, "sending information to... (terminal)" can be understood as the destination of the information being the terminal. This can include sending information to the terminal directly or indirectly. "Receiving information from... (terminal)" can be understood as the source of the information being the terminal, which can include receiving information from the terminal directly or indirectly. The information may undergo necessary processing between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated here.

[0120] Network devices and terminal devices, as well as terminal devices and terminal devices, can communicate through licensed spectrum (licensed spectrum), or through unlicensed spectrum (unlicensed spectrum), or through both licensed spectrum and unlicensed spectrum. Network devices and terminal devices, as well as terminal devices and terminal devices, can communicate through spectrum below 6G, or through spectrum above 6G, or through both spectrum below 6G and spectrum above 6G. The embodiments of the present application do not limit the spectrum resources used between network devices and terminal devices.

[0121] In order to facilitate understanding of the solutions of the embodiments of the present application, first, a brief explanation of the technical terms involved in the embodiments of the present application is given.

[0122] 1. Symbol: Short for time domain symbol, also known as OFDM symbol. It should be noted that time domain symbols can also be named in conjunction with other multiple access methods, which is not limited in this embodiment of the application. The length of the time domain symbol can be different for different subcarrier spacings.

[0123] It should be understood that symbols within a time slot may include three types: downlink (UL) symbols, uplink (DL) symbols, and flexible (F) symbols. Uplink symbols can only be used for uplink transmission, while downlink symbols can only be used for downlink transmission. Flexible symbols have no fixed transmission direction and can be used for uplink or downlink transmission based on control signaling. The symbols in a time slot can be all downlink symbols, all uplink symbols, all flexible symbols, or a mixture of these types of symbols.

[0124] 2. Time unit: A time unit may be a time slot, or a symbol, or a subframe, or a half frame, or a frame, or a mini-subframe, or a mini-time slot, which is not limited in this application.

[0125] 3. Subband: A subband is a portion of a frequency band in a carrier, that is, one or more consecutive physical resource blocks (PRBs) in the frequency domain. In this application, a subband can also be understood as a frequency domain resource.

[0126] 4. Duplexing: Currently, NR includes frequency division duplexing (FDD) and time division duplexing (TDD). Figure 2 is a schematic diagram of the duplexing method provided in an embodiment of the present application.

[0127] The specific form of FDD is shown in (a) of Figure 2. Downlink transmission is performed on the downlink BWP in time slot 0, and uplink transmission can also be performed on the uplink BWP in slot 0. The downlink BWP and the uplink BWP are located on different carriers and are separated in the frequency domain, that is, the uplink BWP and the downlink BWP belong to different frequency bands.

[0128] The specific form of TDD is shown in Figure 2(b). When the center frequency of the downlink BWP is the same as that of the uplink BWP, the bandwidth of the uplink BWP and the downlink BWP can be the same or different (the same situation is shown in Figure 2(b). In this case, the uplink BWP or downlink BWP can be referred to as BWP). At the same time, the terminal device can only perform uplink or downlink transmission. For example, in time slot 0, only downlink transmission can be performed, and in time slot 4, only uplink transmission can be performed. Time slot 3 is a flexible time slot, that is, it can be used for uplink transmission or downlink transmission, but not for uplink and downlink transmission at the same time. The minimum granularity of uplink and downlink transmission switching is a symbol. For example, time slot 3 is a flexible time slot. A flexible time slot can include 14 or 12 OFDM symbols, where the first M symbols are downlink symbols, the last N symbols are uplink symbols, and the middle 14-MN (or 12-MN) symbols are flexible symbols. 0 <= M <= 14, 0 <= N <= 14, and M+N <= 14. Downlink symbols are used for downlink transmission, and uplink symbols are used for uplink transmission. Flexible symbols can be used for both uplink and downlink. The specific transmission direction is notified to the terminal device by the network device through radio resource control (RRC) signaling or downlink control information (DCI) scheduling.

[0129] Although the time division duplex (TDD) method occupies fewer frequency domain resources than the frequency division duplex (FDD) method, since TDD cannot perform simultaneous uplink and downlink transmissions, the more flexible full-duplex method can address the latency issues of TDD. For example, the sub-band full-duplex method (SBFD) can be used. The specific form of SBFD can be shown in Figure 2 (c). In a time slot, such as time slot 0, there is a section of frequency domain resources within the BWP that can be used for uplink transmission. This frequency domain resource allows uplink transmission in time slot 0, reducing the latency of uplink transmission. This section of frequency domain resources is usually called an uplink sub-band. At this time, downlink transmission can also be performed in time slot 0. Network devices can perform uplink and downlink transmissions simultaneously in time slot 0. Terminal devices can also perform uplink and downlink transmissions simultaneously in time slot 0 (i.e., full-duplex terminal devices). At the same time, terminal devices can also perform only uplink or downlink transmissions (half-duplex terminal devices). Compared to the TDD method, the SBFD method has more uplink resources, which can increase uplink coverage and reduce uplink and downlink transmission latency.

[0130] 5.SBFD time slot: The frequency domain resources on the SBFD time slot include two or more sub-bands in different transmission directions.

[0131] 6. Non-SBFD timeslot: In a non-SBFD timeslot, the entire frequency domain resource is used for uplink or downlink transmission. Non-SBFD timeslots, for example, include uplink timeslots, downlink timeslots, or flexible timeslots.

[0132] 7. SBFD System: Current discussions regarding SBFD systems involve the following operating method: network equipment notifies terminal devices of the time-frequency domain resources corresponding to the SBFD uplink and / or downlink subbands; and new terminal device behaviors are introduced for new SBFD-capable terminal devices. Under this operating method, for SBFD-capable terminal devices, when an uplink subband is configured on an SBFD symbol in a downlink timeslot or flexible timeslot, the primary uplink and downlink transmission method is that within the SBFD timeslot, the SBFD-capable terminal device does not expect uplink transmissions outside of the uplink subband, and does not expect downlink transmissions on the uplink subband.

[0133] 8. Sampling rate: the number of samples taken per second.

[0134] FIG3 is a schematic diagram of various resource formats of SBFD provided in an embodiment of the present application.

[0135] In some implementations, the uplink subband of the SBFD timeslot is in the original downlink timeslot, or in the original downlink timeslot and the special timeslot, or in the original downlink timeslot, the special timeslot, and the uplink timeslot.

[0136] As shown in (a) to (c) of FIG3 , the original downlink time slot includes an uplink sub-band and a downlink sub-band, thereby forming an SBFD time slot of the downlink time slot.

[0137] It should also be understood that the embodiment of the present application does not limit the number of SBFD time slots in the downlink time slot. For example, as shown in (c) of FIG3 , all original downlink time slots include uplink sub-bands and uplink sub-bands.

[0138] It should also be understood that the embodiments of the present application do not limit the type of uplink subband in the SBFD time slot to the original time slot. As shown in FIG3(d), the SBFD time slot may include the uplink subband in the original downlink time slot and the special time slot, thereby forming an SBFD time slot of the downlink time slot and an SBFD time slot of the special time slot. As shown in FIG3(e), the SBFD time slot may include the uplink subband in the original downlink time slot, the special time slot, and the uplink time slot, thereby forming an SBFD time slot of the downlink time slot, an SBFD time slot of the special time slot, and an SBFD time slot of the uplink time slot.

[0139] It should be understood that the embodiments of the present application do not limit the center frequency position of the uplink subband and the bandwidth size of the uplink subband in each SBFD time slot. The center frequency position and / or bandwidth size of the uplink subband in different SBFD time slots can be the same or different.

[0140] For example, the uplink sub-band in FIG. 3( a ) and the uplink sub-band in FIG. 3( b ) have different center frequencies, but their bandwidths may be the same.

[0141] For another example, the SBFD time slot includes multiple uplink sub-bands, and different uplink sub-bands have different center frequencies and different bandwidths, as shown in FIG3(f).

[0142] For example, an SBFD timeslot includes multiple uplink subbands, and different uplink subbands can belong to a downlink timeslot, a special timeslot, or an uplink timeslot. As shown in Figure 3(g), an uplink subband can belong to an SBFD timeslot of a downlink timeslot, or an uplink subband can belong to an SBFD timeslot of a special timeslot.

[0143] Currently, legacy devices (i.e., those that do not support SBFD) use full bandwidth or BWP for uplink transmission on uplink symbols. For SBFD-capable devices, to balance uplink transmission in the uplink subband and full bandwidth of the uplink timeslot during SBFD timeslots, they may continue to use the current full bandwidth or BWP for uplink transmission on the uplink subband. This can lead to the following problems: First, using the full bandwidth or BWP to transmit uplink signals on the uplink subband will interfere with the downlink signal reception of the device in the downlink timeslot. This can also interfere with downlink signal reception on legacy devices, especially those with weak interference mitigation capabilities. Second, using the full bandwidth or BWP to transmit uplink signals on the uplink subband results in a relatively high sampling rate. This causes the device to use significantly more resources for uplink transmission on the uplink subband than is required for the subband, resulting in lower transmission efficiency and increased energy consumption. Third, if the SBFD timeslot of the terminal device has multiple uplink subbands (as shown in (f) or (g) of Figure 3), then there is a situation where switching from one uplink subband to another uplink subband occurs. In order to achieve smoother switching between uplink subbands of different bandwidth sizes or center frequencies, it is necessary to widen the transmission bandwidth and increase the corresponding transmission sampling rate when the terminal device is initially working, so that both uplink subbands can be covered, thereby enabling different uplink subbands to operate normally. However, this will also result in low transmission efficiency of the terminal device on the uplink subband and increased energy consumption of the terminal device.

[0144] In view of the above problems, the following will describe in detail with reference to FIG. 4 to FIG. 10 .

[0145] Figure 4 is an interactive diagram of a capability reporting method provided by an embodiment of the present application. It can be understood that the present application uses a network device and a terminal device as an example to illustrate the corresponding method, but the present application does not limit the execution subject of the interactive diagram. For example, the method implemented by the network device can also be implemented by a module of the network device (such as a chip, a chip system or a processor), and can also be implemented by a logical node, a logical module or software that can implement all or part of the functions of the network device. For another example, the method implemented by the terminal device can also be implemented by a module of the terminal device (such as a chip, a chip system or a processor), and can also be implemented by a logical node, a logical module or software that can implement all or part of the functions of the terminal device.

[0146] S410: Send capability information to the network device.

[0147] Among them, the capability information indicates at least one of the following: the first uplink transmission capability of the terminal device supporting full bandwidth; the second uplink transmission capability of the terminal device supporting uplink sub-band; the third uplink transmission capability of the terminal device supporting uplink sub-band and full bandwidth; the fourth uplink transmission capability of the terminal device supporting sub-band full-duplex SBFD with interval switching; or the fifth uplink transmission capability of the terminal device supporting SBFD without interval switching.

[0148] Specifically, the terminal device sends capability information to the network device when registering with the network; or the terminal device sends capability information to the network device when the capability is changed.

[0149] It should be understood that capability information is used to indicate the type of uplink transmission capability supported by the terminal device for SBFD. The terminal device reports the uplink transmission capability directly indicated by the capability information to the network device, which can be viewed as an enumerated capability reporting method, reporting the terminal device's SBFD-related capability information to the network device.

[0150] As a possible implementation manner, the capability information includes first capability information, and the first capability information is used to indicate any one of the first uplink transmission capability, the second uplink transmission capability, the third uplink transmission capability, the fourth uplink transmission capability or the fifth uplink transmission capability.

[0151] Optionally, the capability information further includes second capability information, where the second capability information is used to indicate capabilities other than the capabilities indicated by the first capability information.

[0152] It should be understood that when a terminal device registers with the network, the terminal device sends the first capability information to the network device. If the terminal device also has other uplink transmission capabilities, it can report them to the network device through the second capability information. In other words, the basic capability information of the terminal device is reported to the network device through the first capability information, and the additional capability information of the terminal device is reported to the network device through the second capability information.

[0153] The above-mentioned SBFD uplink transmission capability types will be described in detail below with reference to Figure 5. Figure 5 is a schematic diagram of an uplink transmission capability provided by an embodiment of the present application. The time-frequency resources shown in Figure 5 are illustrated by taking 5 time slots or 10 time slots as an example.

[0154] The first uplink transmission capability of a terminal device supporting full bandwidth can be understood as the uplink transmission capability of the terminal device not supporting SBFD, that is, the uplink transmission capability of the terminal device supporting TDD. It can also be referred to as the first uplink transmission capability of the terminal device supporting BWP. In other words, the terminal device has the ability to perform uplink transmission at the full bandwidth or BWP.

[0155] Exemplarily, as shown in (a) of FIG5 , the terminal device supports full-bandwidth uplink transmission in the uplink time slot, and uplink and downlink transmission behaviors cannot be scheduled on the same symbol.

[0156] The second uplink transmission capability of a terminal device supporting only an uplink subband can be understood as the terminal device performing uplink transmission on the first uplink subband. This can also be referred to as the second uplink transmission capability supporting only SBFD (SBFD only). The first uplink subband can cover multiple time slots in the time domain, and in different time slots, the center frequency and bandwidth of the first uplink subband are the same. Alternatively, the first uplink subband can include multiple different second uplink subbands, and the center frequencies and / or bandwidths of the second uplink subbands can be different.

[0157] Exemplarily, as shown in (b) of FIG5 , the terminal device may perform uplink transmission on the first uplink subband of the downlink time slot, may perform uplink transmission on the first uplink subband of the uplink time slot, or may perform uplink transmission on the first uplink subband of the special time slot.

[0158] The third uplink transmission capability of a terminal device supporting uplink sub-band and full bandwidth can be understood as supporting both the first and second uplink transmission capabilities. However, the terminal device performs uplink transmission using either the first or second capability. This means that the two uplink transmission capabilities are not available simultaneously during uplink transmission. The third uplink transmission capability can also be referred to as a select one uplink transmission capability.

[0159] For example, the time-frequency resources on the left side of FIG5 (c) are the second uplink transmission capability of the terminal device supporting the uplink sub-band, and the terminal device shown on the right side of FIG5 (c) supports the first uplink transmission capability of the full bandwidth. Through a single network configuration, the terminal device can perform uplink transmission on the time-frequency resources corresponding to the first uplink transmission capability or the second uplink transmission capability.

[0160] Specifically, the terminal device can send capability information indicating the third uplink transmission capability to the network device through radio resource control (RRC), and through downlink control information (DCI) or media access control (MAC), enable the terminal device to perform uplink transmission on the resources corresponding to the first uplink transmission capability or the second uplink transmission capability.

[0161] The terminal device supports the fourth uplink transmission capability of SBFD band interval switching, which may include understanding one: the terminal device supports the first uplink transmission capability and the second uplink transmission capability at the same time, and has the ability to switch over the full bandwidth and the uplink sub-band through the first interval duration for uplink transmission. Alternatively, it may also include understanding two: the terminal device includes different uplink sub-bands on the SBFD time slot, and in this case, the terminal device supports the ability to switch over different uplink sub-bands through the second interval duration for uplink transmission. Alternatively, it may also include understanding three: the terminal device supports the first uplink transmission capability and the second uplink transmission capability at the same time, switches over the full bandwidth and the uplink sub-band through the first interval duration for uplink transmission, and switches over different uplink sub-bands through the second interval duration for uplink transmission.

[0162] Optionally, when the capability information is used to indicate the fourth uplink transmission capability, the terminal device sends indication information of a first interval duration to the network device, and / or sends indication information of a second interval duration; the first interval duration is used for switching between the uplink sub-band and the full bandwidth, and the second interval duration is used for switching between different uplink sub-bands.

[0163] As a possible implementation manner, when the capability information is used to indicate the fourth uplink transmission capability, the terminal device may further send indication information of the first interval duration to the network device.

[0164] Exemplarily, as shown in (d) of Figure 5 , the terminal device supports uplink transmission on the first uplink sub-band of the SBFD time slot, and also supports uplink transmission on the full bandwidth of the uplink time slot. At this time, there is a first interval duration in the time domain between the uplink transmission resources corresponding to the uplink sub-band of the SBFD time slot and the full bandwidth of the uplink time slot. The first interval duration can be recorded as "SwitchGAP", or as shown in (d) of Figure 5 , referred to as "G". The terminal device does not perform uplink transmission within the first interval duration, but switches the uplink sub-band bandwidth and the full bandwidth (or BWP). For example, the terminal device switches the transmission bandwidth from the bandwidth size corresponding to the uplink sub-band to the bandwidth size corresponding to the full bandwidth within the first interval duration.

[0165] It should be understood that the embodiment of the present application does not limit the value of the first interval duration. For example, the first interval duration may include one or more of the following values: 0us, 35us, 70us, 105us, 140us or 210us.

[0166] It should be understood that the first interval duration shown in (d) of FIG5 is located in the SBFD time slot, and the first interval duration may also be located in the uplink time slot or special time slot of the time-frequency resources corresponding to the full bandwidth.

[0167] As a possible implementation manner, when the capability information is used to indicate the fourth uplink transmission capability, the terminal device may further send indication information of the second interval duration to the network device.

[0168] Exemplarily, if the SBFD time slot includes multiple uplink sub-bands, and the center frequencies and / or bandwidths of different uplink sub-bands are different, for example, as shown in (f) or (g) of Figure 3 , there is a second interval duration in the time domain between the uplink transmission resources corresponding to different uplink sub-bands. The second interval duration can be recorded as "subband-SwitchGAP", or the second interval duration can also be called the subband switching interval duration. The terminal device does not perform uplink transmission within the second interval duration, but switches between different uplink sub-bands. For example, the terminal device switches the transmission bandwidth from the bandwidth size corresponding to uplink sub-band #1 to the bandwidth size corresponding to uplink sub-band #2 during the second interval duration.

[0169] It should be understood that the embodiment of the present application does not limit the value of the second interval duration. For example, the second interval duration may include one or more of the following values: 0us, 35us, 70us, 105us, 140us or 210us.

[0170] Optionally, for the method in which the capability information indicates the fourth uplink transmission capability and sends indication information of the second interval duration, there can also be an equivalent indication method, in which the capability information indicates the second uplink transmission capability and sends indication information of the second interval duration. At this time, the frequency centers and / or bandwidth sizes of different uplink sub-bands are different.

[0171] As a possible implementation manner, when the capability information is used to indicate the fourth uplink transmission capability, the terminal device may further send indication information of the first interval duration and indication information of the second interval duration to the network device.

[0172] It should be understood that the first interval duration and the second interval duration may be equal or unequal.

[0173] As a possible implementation manner, when the capability information indicates the second uplink transmission capability and the fourth uplink transmission capability, the terminal device sends indication information of the first interval duration or the second interval duration to the network device.

[0174] When the first interval duration is equal to the second interval duration, the terminal device may further send indication information of the first interval duration or the second interval duration to the network device.

[0175] The terminal device supports the fifth uplink transmission capability of SBFD without interval switching, which can be understood as the terminal device supporting the first uplink transmission capability and the second uplink transmission capability at the same time, and the terminal device does not need to switch the first uplink transmission capability and the second uplink transmission capability according to the first interval duration, that is, the terminal device can achieve seamless switching of the first uplink transmission capability and the second uplink transmission capability. Alternatively, it can also be understood as the terminal device including different uplink sub-bands on the SBFD time slot. At this time, the terminal device does not need to switch the uplink transmission on different uplink sub-bands according to the second interval duration, that is, the terminal device can achieve seamless switching of uplink transmission on different second sub-bands.

[0176] For example, as shown in (e) of Figure 5, the terminal device supports uplink transmission on the first uplink sub-band of the SBFD time slot, and also supports uplink transmission on the full bandwidth of the uplink time slot. When the uplink signal transmission is performed continuously, there is no need for an interval in the time domain between the uplink transmission resources corresponding to the full bandwidth and the first uplink sub-band.

[0177] It should be understood that when the first time interval corresponding to the fourth uplink transmission capability of the terminal device is 0 us, the fourth uplink transmission capability and the fifth uplink transmission capability of the terminal device are equivalent.

[0178] Exemplarily, if the SBFD time slot includes multiple uplink sub-bands, and the center frequencies and / or bandwidths of different uplink sub-bands are different, for example, as shown in (f) or (g) of Figure 3, then when the terminal device performs continuous uplink signal transmission, there is no need for a time interval in the time domain between the uplink transmission resources corresponding to different uplink sub-bands.

[0179] It should be understood that when the second time interval corresponding to the fourth uplink transmission capability of the terminal device is 0 us, the fourth uplink transmission capability and the fifth uplink transmission capability of the terminal device are equivalent.

[0180] It should be understood that there are differences in strength among the above-mentioned uplink transmission capabilities, and the order of the uplink transmission capabilities from high to low is: the fifth uplink transmission capability, the fourth uplink transmission capability, the third uplink transmission capability, the second uplink transmission capability and the first uplink transmission capability.

[0181] Optionally, if the capability information is used to indicate one of the above uplink transmission capabilities, the capability information is also used to indicate that the terminal device can be compatible with an uplink transmission capability that is weaker than that indicated by the capability information.

[0182] Optionally, in S420, the network device sends first indication information to the terminal device, and the terminal device receives the first indication information from the network device.

[0183] Among them, the first indication information indicates one of the following: the network device configures the first uplink transmission capability for the terminal device; the network device configures the second uplink transmission capability for the terminal device; the network device configures the fourth uplink transmission capability for the terminal device; or the network device configures the fifth uplink transmission capability for the terminal device.

[0184] It should be understood that since the third uplink transmission capability is the uplink transmission capability that the terminal device can support for the full bandwidth and the uplink sub-band, the terminal device can only use one of the uplink transmission capabilities when performing uplink transmission. For the network device, after receiving the capability information about the third uplink transmission capability, the first indication information indicates the first uplink transmission capability or the second uplink transmission capability.

[0185] Optionally, in S430, the terminal device sends an uplink signal to the network device according to the capability information.

[0186] In the above technical solution, the terminal device reports its specific uplink transmission capabilities for SBFD to the network device, which helps the terminal device subsequently use different transmission bandwidths for uplink transmission based on the specific uplink transmission capabilities on the resources scheduled by the network device. Compared to the solution of using the full bandwidth as the transmission bandwidth to ensure compatibility with SBFD uplink sub-band and full-bandwidth uplink transmission, the solution of the embodiment of the present application can reduce the interference of uplink transmission on downlink transmission, improve the energy efficiency of the terminal device, reduce the energy consumption of the terminal device, and thus improve system performance.

[0187] FIG6 is an interactive diagram of another capability reporting method provided in an embodiment of the present application.

[0188] S610, the terminal device sends capability information to the network device, and the capability information indicates at least one of the following: the first uplink transmission capability of the terminal device supporting full bandwidth; the second uplink transmission capability of the terminal device supporting uplink sub-band; the third uplink transmission capability of the terminal device supporting uplink sub-band and full bandwidth; the fourth uplink transmission capability of the terminal device supporting sub-band full-duplex SBFD with interval switching; or the fifth uplink transmission capability of the terminal device supporting SBFD without interval switching.

[0189] It should be understood that a detailed description of the specific uplink transmission capability can be referred to S410 and will not be repeated here.

[0190] S620, the network device sends first indication information to the terminal device according to the capability information, where the first indication information is used to indicate the uplink transmission capability configured by the network device for the terminal device.

[0191] It should be understood that a detailed enumeration description of the first indication information can be referred to S420 and will not be repeated here.

[0192] Optionally, when the first indication information instructs the network device to configure the fourth uplink transmission capability for the terminal device, the network device sends second indication information to the terminal device. The second indication information is used to indicate the time-frequency resource location where the terminal device does not perform uplink transmission when switching between an uplink sub-band and full bandwidth, and / or the second indication information is used to indicate the time-frequency resource location where the terminal device does not perform uplink transmission when switching between different uplink sub-bands.

[0193] Optionally, the second indication information is preconfigured in the terminal device.

[0194] The terminal device can determine the location of the switching interval between the full bandwidth and the first uplink sub-band, and / or the location of the switching interval between different second uplink sub-bands based on the second indication information when the first interval duration and / or the second interval duration is insufficient, or the terminal device does not detect the reserved first interval duration and / or the second interval duration in the scheduling authorized by the network device.

[0195] In one possible implementation, the second indication information includes first truncation indication information and / or second truncation indication information, the first truncation indication information is used to indicate the time-frequency resource position where the terminal device does not perform uplink transmission when switching between the uplink sub-band and the full bandwidth, and the second truncation indication information is used to indicate the time-frequency resource position where the terminal device does not perform uplink transmission when switching between different uplink sub-bands.

[0196] For example, the first truncation indication information specifically includes the full bandwidth position information of the uplink time slot, or includes the position information of the uplink sub-band of the SBFD time slot. When the switching interval between the full bandwidth and the uplink sub-band is insufficient, the first truncation indication information is specifically used to instruct the terminal device to perform truncation or perforation at the full bandwidth position, that is, to preserve the transmission of the uplink sub-band. Alternatively, when the switching interval between the full bandwidth and the uplink sub-band is insufficient, the first truncation indication information is specifically used to instruct the terminal device to perform truncation or perforation at the uplink sub-band position, that is, to preserve the uplink transmission of the full bandwidth.

[0197] For another example, the first truncation indication information specifically includes a tail data stream or a head data stream. The tail data stream specifically means the tail data stream corresponding to the bandwidth resource before the first interval duration, and the head data stream specifically means the head data stream corresponding to the bandwidth resource after the first interval duration. When the switching interval between the full bandwidth and the uplink sub-band is insufficient, the first truncation indication information is specifically used to instruct the terminal device to truncate or punch holes at the tail data stream corresponding to the first interval duration, that is, to preserve the uplink transmission after the first interval duration. Specifically, for example, the bandwidth resource before the first interval duration is the uplink sub-band, and the first truncation indication information instructs the terminal device to truncate or punch holes at the tail data stream corresponding to the uplink sub-band, that is, to preserve the uplink transmission of the full bandwidth after the first interval duration. Or when the switching interval between the full bandwidth and the uplink sub-band is insufficient, the first truncation indication information is specifically used to instruct the terminal device to truncate or punch holes at the head data stream corresponding to the first interval duration, that is, to preserve the uplink transmission before the first interval duration. Specifically, the bandwidth resource after the first interval duration is full bandwidth (or BWP), and the first truncation indication information instructs the terminal device to truncate or puncture the header data flow corresponding to the full bandwidth, that is, to preserve the uplink transmission of the uplink subband before the first interval duration.

[0198] It should be understood that the content included in the first truncation indication information may also be predefined in the terminal device, that is, the first truncation indication information is not transmitted via the air interface.

[0199] It should also be understood that predefining the first truncation indication information in the terminal device can also serve as a way for the terminal to resolve transmission conflicts when conflicts arise between the uplink subband and the full bandwidth at the symbol level or the channel level scheduling.

[0200] For example, the second truncation indication information specifically includes the ordering of different uplink subbands of the SBFD time slot. When the switching interval between different uplink subbands is insufficient, the second truncation indication information is specifically used to indicate the truncation or puncturing position determined by the terminal device according to the ordering of different uplink subbands, that is, the second truncation indication information is specifically used to indicate the position where the terminal device does not perform uplink transmission according to the ordering of different uplink subbands.

[0201] Specifically, the order of different uplink subbands is determined based on the bandwidth of different uplink subbands. For example, the uplink subband with a larger bandwidth has a higher order and a higher priority; if the order of different uplink subbands is specifically an index, then the uplink subband with a smaller index has a higher priority and a larger bandwidth. For another example, the uplink subband with a smaller bandwidth has a higher order and a higher priority; if the order of different uplink subbands is specifically an index, then the uplink subband with a larger index has a higher priority and a smaller bandwidth. The embodiment of the present application does not limit the specific meaning corresponding to the order of different second uplink subbands. It should be understood that the second truncation indication information indicates that the position where uplink transmission is not performed may belong to the uplink subband with the largest index, or the uplink subband with the smallest index; or it may belong to the uplink subband with the largest bandwidth, or it may belong to the uplink subband with the smallest bandwidth. The embodiment of the present application does not limit this.

[0202] For another example, the second truncation indication information specifically includes the tail data stream or the head data stream. The specific meaning of the tail data stream may be the tail data stream corresponding to the second interval duration, and the specific meaning of the head data stream may be the head data stream corresponding to the second interval duration. When the switching interval between different uplink sub-bands is insufficient, the second truncation indication information is specifically used to instruct the terminal device to perform truncation or puncturing at the tail data stream corresponding to the second interval duration, that is, to preserve the uplink transmission after the second interval duration. Alternatively, when the switching interval between different uplink sub-bands is insufficient, the second truncation indication information is specifically used to instruct the terminal device to perform truncation or puncturing at the head data stream corresponding to the second interval duration, that is, to preserve the uplink transmission before the second interval duration.

[0203] It should be understood that the content included in the second truncation indication information may also be predefined in the terminal device, that is, the second truncation indication information is not transmitted through the air interface.

[0204] It should also be understood that predefining the second truncation indication information in the terminal device can also serve as a way for the terminal to resolve transmission conflicts when conflicts arise in symbol-level or channel-level scheduling of different uplink subbands.

[0205] Further, if the first truncation indication information and the second truncation indication information both include a header data stream or a tail data stream, the network device may send the first truncation indication information or the second truncation indication information to the terminal device for determining a position between the uplink sub-band and the full bandwidth where no uplink transmission is performed, and for determining a position between different uplink sub-bands where no uplink transmission is performed.

[0206] Optionally, the network device sends network configuration parameter information to the terminal device, where the parameter information is used to indicate time-frequency information, channel resource information, SBFD characteristic parameter information, etc. configured by the network device for the terminal device.

[0207] S630: The network device dispatches resource information to the terminal device.

[0208] As a possible implementation manner, the network device schedules resource information to the terminal device according to the TDD parameters, SBFD parameters and capability information.

[0209] Specifically, if the network device configures the first uplink transmission capability to the terminal device in S620, the corresponding resource information in S630 includes information such as the full bandwidth size, full bandwidth transmission type, etc. For example, the resource information of the first uplink transmission capability may be as shown in FIG5(a).

[0210] If the network device configures the second uplink transmission capability for the terminal device in S620, the corresponding resource information in S630 includes information such as the bandwidth size and center frequency of the uplink subband of the SBFD timeslot. For example, the resource information of the second uplink transmission capability may be as shown in FIG5(b).

[0211] If the network device configures the fourth uplink transmission capability for the terminal device in S620, the corresponding resource information in S630 includes information such as the bandwidth size and center frequency of the uplink subband of the SBFD timeslot, the bandwidth size and time domain position of the full bandwidth, and the position of the first interval duration or the second interval duration. For example, the resource information of the fourth uplink transmission capability may be as shown in (d) of Figure 5 .

[0212] If the network device configures the fifth uplink transmission capability for the terminal device in S620, the corresponding resource information in S630 includes information such as the bandwidth size and center frequency of the uplink subband of the SBFD timeslot, the bandwidth size and time domain location of the full bandwidth, etc. For example, the resource information of the fifth uplink transmission capability may be as shown in (e) of Figure 5 .

[0213] S640, the terminal device sends an uplink signal to the network device according to the capability information, the first indication information and the resource information.

[0214] In a possible implementation, when the capability indicated by the first indication information is consistent with the capability indicated by the capability information, an uplink signal is sent to the network device using the transmission bandwidth.

[0215] In some implementations, the transmission bandwidth may include bandwidth resources corresponding to the uplink transmission capability, and the terminal device directly uses the bandwidth resources corresponding to the uplink transmission capability as the transmission bandwidth. For example, for the first uplink transmission capability, the network device configures the terminal device with a BWP (or full-band working bandwidth); for the second uplink transmission capability, the network device configures the terminal device with a sub-band working bandwidth.

[0216] In certain implementations, a network device configures bandwidth resources and valid resource block (RB) resources corresponding to an uplink transmission capability for a terminal device. The terminal device may then determine a transmission bandwidth based on the bandwidth resources and valid RB resources. For example, for a first uplink transmission capability, the transmission bandwidth is determined based on the full-band operating bandwidth and valid RB resources; for a second uplink transmission capability, the transmission bandwidth is determined based on the sub-band operating bandwidth and valid RB resources.

[0217] The following describes in detail an example in which a terminal device directly uses bandwidth resources for uplink transmission capability as transmission bandwidth.

[0218] Specifically, in case one, if the capability information and the first indication information indicate the first uplink transmission capability, and the resource information is the resource information corresponding to the first uplink transmission capability, then the network device configures BWP (or full-band working bandwidth) for the terminal device. The terminal device can use BWP and the first sampling rate corresponding to BWP on the uplink symbols or flexible symbols of the uplink time slot or special time slot to send an uplink signal to the network device.

[0219] Case 2: If the capability information and the first indication information indicate the second uplink transmission capability, and the resource information is the resource information corresponding to the second uplink transmission capability, at this time, the network device configures the sub-band working bandwidth for the terminal device, then the terminal device uses the sub-band working bandwidth and the second sampling rate corresponding to the sub-band working bandwidth on the uplink sub-band of the SBFD time slot to send an uplink signal to the network device.

[0220] It should be understood that the bandwidth corresponding to the sub-band transmission working bandwidth is smaller than the full-band transmission working bandwidth, and the second sampling rate is smaller than the first sampling rate.

[0221] Case three, if the capability information and the first indication information indicate the third uplink transmission capability, the resource information may be the resource information corresponding to the first uplink transmission capability or the second uplink transmission capability, then the terminal device sends an uplink signal to the network device through any one of the above two working bandwidths and sampling rates.

[0222] Case four, if the capability information and the first indication information indicate the fourth uplink transmission capability, the resource information is the resource information corresponding to the first uplink transmission capability, and at this time, the network device configures the BWP and sub-band working bandwidth for the terminal device, then the terminal device can use the sub-band working bandwidth and the second sampling rate on the first uplink sub-band of the SBFD time slot to send an uplink signal to the network device, and use the BWP and the first sampling rate on the uplink symbol or flexible symbol of the uplink time slot or special time slot to send an uplink signal to the network device.

[0223] That is, the terminal device uses different transmit operating bandwidths and sampling rates for the uplink sub-band and uplink full-band. The uplink full-band here can be understood as the full bandwidth or BWP of the uplink symbols in the uplink timeslot or special timeslot.

[0224] In some possible implementations, if the first interval duration is sufficient, the terminal device does not perform uplink transmission during the first interval duration, and switches between the sub-band working bandwidth and BWP, and between the second sampling rate and the first sampling rate during the first interval duration.

[0225] In some possible implementations, if the first interval duration is insufficient or the terminal device does not detect the reserved first interval duration in the scheduling authorized by the network device, the terminal device truncates the uplink transmission according to the position of the time-frequency resources indicated by the first truncation indication information, and switches between the sub-band working bandwidth and BWP, and switches between the second sampling rate and the first sampling rate at the position of the time-frequency resources.

[0226] It should be understood that the first truncation indication information has been described in detail above and will not be repeated here.

[0227] Case five: if the capability information and the first indication information indicate the fourth uplink transmission capability, the resource information is the resource information corresponding to the fourth uplink transmission capability, and at this time, the network device configures different sub-band working bandwidths for the terminal device, then the terminal device can use different sub-band working bandwidths and different second sampling rates on different uplink sub-bands of the SBFD time slot to send uplink signals to the network device.

[0228] That is, the terminal device uses different transmission working bandwidths and sampling rates for different uplink sub-bands.

[0229] In some possible implementations, if the second interval duration is sufficient, the terminal device does not perform uplink transmission during the second interval duration, and switches between different sub-band working bandwidths and between different second sampling rates during the second interval duration.

[0230] In some possible implementations, if the second interval duration is insufficient or the terminal device does not detect the reserved second interval duration in the scheduling authorized by the network device, the terminal device truncates the uplink transmission according to the position of the time-frequency resources indicated by the second truncation indication information, and switches between different sub-band working bandwidths and different second sampling rates at the position of the time-frequency resources.

[0231] It should be understood that if the first uplink subband in case four includes different uplink subbands, the terminal device can superimpose the uplink transmission method in case five on the time-frequency resource portion including the different uplink subbands.

[0232] Case six, if the capability information and the first indication information indicate the fifth uplink transmission capability, and the resource information is the resource information corresponding to the fifth uplink transmission capability, then the network device configures the BWP and sub-band working bandwidth for the terminal device, and the terminal device can have two ways of sending uplink signals. Method one, the terminal device can use the full-band transmission working bandwidth and the first sampling rate to send uplink signals to the network device. Method two, the terminal device can achieve seamless switching between the uplink full band and the uplink sub-band (that is, the first interval duration is 0us). At this time, the terminal device can use the sub-band working bandwidth and the second sampling rate on the uplink sub-band, and use the full-band transmission working bandwidth and the first sampling rate on the uplink full band to send uplink signals to the network device.

[0233] It should be understood that if the terminal device has strong capabilities, uplink transmission can be achieved through mode 2 under the fifth uplink transmission capability. If the terminal device has weak capabilities, uplink transmission can be achieved through mode 1 under the fifth uplink transmission capability.

[0234] Case seven, if the capability information and the first indication information indicate the fifth uplink capability information, the resource information is the resource information corresponding to the fifth uplink transmission capability, and at this time, the network device configures different sub-band working bandwidths for the terminal device, and the terminal device can have two ways of sending uplink signals. Method one, the terminal device can use the combined bandwidth corresponding to different second uplink sub-band working bandwidths and the second sampling rate corresponding to the combined bandwidth to send uplink signals to the network devices on multiple second uplink sub-bands, wherein the combined bandwidth includes the frequency range of multiple second uplink sub-band authorized working channels. Method two, the terminal device can use different sub-band working bandwidths and different second sampling rates to send uplink signals to the network devices on multiple second uplink sub-bands.

[0235] In a possible implementation, if the capability indicated by the terminal device capability information is inconsistent with the capability indicated by the first indication information, an uplink signal is sent to the network device based on an uplink transmission capability that is not higher than the uplink transmission capability indicated by the capability information.

[0236] It should be understood that the inconsistency between the terminal device capability information and the working mode may include: the first inconsistency situation, the capability indicated by the terminal device capability information is higher than the capability indicated by the first indication information. For this inconsistency situation, it may be caused by insufficient capabilities of the network device, or lagging development of network support capabilities. Or, it may also be because the network device assesses that the current business of the terminal device does not require such strong capabilities. The second inconsistency situation is that the capability indicated by the terminal device capability information is lower than the capability indicated by the first indication information. For the second inconsistency situation, it may be due to the decoding of the received signal by the terminal device resulting in a false alarm, which in turn causes the terminal device capability information to be lower than the capability information reported to the network device.

[0237] It should be understood that the uplink transmission capabilities are ranked from highest to lowest as follows: fifth uplink transmission capability, fourth uplink transmission capability, third uplink transmission capability, second uplink transmission capability, and first uplink transmission capability. The capabilities of the terminal devices required by the above-mentioned operating modes are ranked from highest to lowest as follows: fifth operating mode, fourth operating mode, second operating mode, and first operating mode.

[0238] Specifically, when the capability indicated by the first indication information is lower than the capability indicated by the capability information, the terminal device may send an uplink signal to the network device according to the capability indicated by the first indication information.

[0239] Specifically, when the capability indicated by the first indication information is higher than the capability indicated by the capability information, the terminal device sends an error indication to the network device, or the terminal device sends an uplink signal to the network device based on the capability not higher than the capability indicated by the capability information.

[0240] Exemplarily, if the capability information of the terminal device is the fourth uplink transmission capability, and the capability indicated by the first indication information is the fifth uplink transmission capability, the terminal device can perform uplink transmission under the fourth uplink transmission capability.

[0241] If there is a conflict in the resources scheduled by network devices, it can be resolved in the following ways.

[0242] In a possible implementation, if the capability indicated by the first indication information is inconsistent with the capability corresponding to the scheduled resource information, the terminal device sends a scheduling error indication message to the network device and does not perform scheduling.

[0243] Specifically, if the working mode indicates the first uplink transmission capability, but the S630 network device schedules the sub-band working bandwidth corresponding to the second uplink transmission capability to the terminal device, the terminal device determines that the scheduling is wrong and does not perform the scheduling.

[0244] For example, if the first indication information indicates the first uplink transmission capability, that is, the network device should schedule the terminal device to use the full-band working bandwidth to work on the flexible symbols of the special time slot and the uplink symbols of the uplink time slot, but the S630 network device schedules the terminal device to use the sub-band working bandwidth to work on the uplink sub-band of the uplink symbol, then the terminal device determines that an error occurs in the scheduling of the network device, and the terminal device does not execute the scheduling.

[0245] In one possible implementation, if the frequency domain range scheduled by the network device is larger than the frequency domain range corresponding to the uplink transmission capability indicated by the first indication information, the terminal device does not perform the scheduling.

[0246] Specifically, if the first indication information indicates the second uplink transmission capability, and the network device configures an uplink subband for the terminal device, the uplink subband may be one or more of a subband in a downlink timeslot, a subband in a special timeslot, or a subband in an uplink timeslot. If the scheduled uplink subband frequency domain range exceeds the subband frequency domain range configured by the network, the terminal device performs the scheduled transmission.

[0247] In one possible implementation, if the S620 network device configures the fourth uplink transmission capability for the terminal device, the terminal device implements switching between the uplink sub-band and the uplink full-band during the uplink transmission process according to the first interval duration indicated by the S610 capability information; or the terminal device implements switching between different uplink sub-bands during the uplink transmission process according to the second interval duration indicated by the S610 capability information.

[0248] Furthermore, when the terminal device does not detect the reserved first interval duration and / or second interval duration in the scheduling authorized by the network device, or the configured first interval duration and / or second interval duration is insufficient, the terminal device does not perform uplink transmission according to the time-frequency resource position indicated by the predefined or received second indication information.

[0249] It should be understood that the predefined or received second indication information has been described in detail in the above content and will not be repeated here.

[0250] The uplink transmission capability used by the terminal device can be updated in the following manner: Method 1 includes steps S651-a and S651-b. Method 2 includes step S652.

[0251] Optionally, S651-a, the terminal device sends auxiliary information to the network device, where the auxiliary information is used to indicate at least one of the following: a first uplink transmission capability, a second uplink transmission capability, a fourth uplink transmission capability, or a fifth uplink transmission capability.

[0252] It should be understood that the auxiliary information is used to indicate the uplink transmission capability required by the terminal device.

[0253] As a possible implementation method, the terminal device determines auxiliary information by identifying the current working scenario, or business requirements (such as short-latency business requirements), or the terminal's own power consumption (energy-saving requirements) and other information.

[0254] As a possible implementation manner, the auxiliary information is used to indicate capabilities other than the current uplink transmission capability of the terminal device.

[0255] As a possible implementation manner, the auxiliary information includes the first information and the second information, or the auxiliary information includes the first information.

[0256] The first information is used to indicate a change in the current uplink transmission capability of the terminal device, and the second information indicates capabilities other than those indicated by the first capability information.

[0257] Optionally, in S651-b, the network device sends third indication information to the terminal device based on the auxiliary information, where the third indication information indicates one of the following: the network device configures a first uplink transmission capability for the terminal device; the network device configures a second uplink transmission capability for the terminal device; the network device configures a fourth uplink transmission capability for the terminal device; or the network device configures a fifth uplink transmission capability for the terminal device.

[0258] Specifically, the network device sends the second indication information to the terminal device through RRC, MAC or DCI.

[0259] It should be understood that the above steps S651 - a and S651 - b are to report and update the desired capabilities of the terminal device by displaying auxiliary information.

[0260] Optionally, S652, the network device actively identifies the service demand and sends a third indication message to the terminal device.

[0261] Specifically, the network device proactively identifies current service model requirements (such as short-latency service requirements) and determines new uplink transmission capabilities to configure for the terminal device.

[0262] FIG7 is an interactive diagram of another capability reporting method provided in an embodiment of the present application.

[0263] S710a, the terminal device sends first capability information to the network device, where the first capability information is used to indicate any one of the following capabilities: a first uplink transmission capability, a second uplink transmission capability, a third uplink transmission capability, a fourth uplink transmission capability, or a fifth uplink transmission capability.

[0264] Optionally, S710b, the terminal device sends second capability information to the network device, where the second capability information is used to indicate other capabilities in addition to the capabilities indicated by the first capability information.

[0265] It should be understood that the first capability information and the second capability information may be reported to the network device together in the same message, or may be reported to the network device separately in different messages.

[0266] It should be understood that if the terminal device reports the first capability information but does not report the second capability information, the terminal device supports the capability indicated by the first capability information.

[0267] For example, the first capability information indicates the first uplink transmission capability, and the terminal device only supports the full-bandwidth uplink transmission capability.

[0268] It should also be understood that if the terminal device reports both the first capability information and the second capability information, the terminal device supports multiple uplink transmission capabilities.

[0269] For example, the first capability information indicates a first uplink transmission capability, and the second capability information may be used to indicate at least one of a second uplink transmission capability, a fourth uplink transmission capability, or a fifth uplink transmission capability. In addition to supporting the first uplink transmission capability, the terminal device may also support other uplink transmission capabilities, which is not limited in the embodiments of the present application.

[0270] It should be understood that a detailed description of the specific uplink transmission capability can be referred to S410 and will not be repeated here.

[0271] Optionally, S720, the network device sends fourth indication information to the terminal device, where the fourth indication information is used to instruct the network device to configure capabilities other than the capabilities indicated by the first capability information for the terminal device.

[0272] It should be understood that if the network device does not send the fourth indication information, the terminal device can perform uplink transmission through the capability indicated by the first capability information.

[0273] For example, if the first capability information indicates the first uplink transmission capability, the terminal device performs uplink transmission using the first uplink transmission capability, i.e., the TDD working mode of a normal terminal device. The fourth indication information instructs the network device to configure any one of the second uplink transmission capability, the fourth uplink transmission capability, or the fifth uplink transmission capability for the terminal device.

[0274] It should be understood that when the fourth indication information instructs the network device to configure the fourth uplink transmission capability for the terminal device, the network device sends the second indication information to the terminal device. Alternatively, the second indication information is preconfigured in the terminal device. For a detailed description of the second indication information, please refer to S620 and will not be repeated here.

[0275] S730: The network device dispatches resource information to the terminal device.

[0276] It should be understood that S730 is similar to S630 and will not be described in detail here.

[0277] S740: The terminal device sends an uplink signal to the network device based on the resource information and capability information.

[0278] Specifically, when the terminal device does not receive the fourth indication information, the terminal device sends an uplink signal to the network device based on the resource information and capability information.

[0279] It should be understood that when the resources required by the capability indicated by the capability information conflict with the scheduled resource information, the specific processing method can be referred to S740 and will not be described in detail here.

[0280] Optionally, when the terminal device receives the fourth indication information, the terminal device sends an uplink signal to the network device according to the fourth indication information, resource information and capability information.

[0281] It should be understood that the detailed process of this situation can be referred to S640 and will not be described in detail here.

[0282] The uplink transmission capability used by the terminal device can be updated in the following manner: Method 1 includes steps S751-a and S751-b. Method 2 includes step S752.

[0283] Optionally, S751-a, the terminal device sends auxiliary information to the network device, where the auxiliary information includes the first information and the second information, or the auxiliary information includes the first information.

[0284] The first information is used to indicate a change in the current uplink transmission capability of the terminal device, and the second information indicates capabilities other than those indicated by the first capability information. As a possible implementation, the terminal device determines the auxiliary information by identifying the current working scenario, service requirements (such as short-latency service requirements), or the terminal's own power consumption (energy-saving requirements), and other information.

[0285] Optionally, in S751-b, the network device sends third indication information to the terminal device based on the auxiliary information, where the third indication information indicates one of the following: the network device configures a first uplink transmission capability for the terminal device; the network device configures a second uplink transmission capability for the terminal device; the network device configures a fourth uplink transmission capability for the terminal device; or the network device configures a fifth uplink transmission capability for the terminal device.

[0286] As a possible implementation manner, if the auxiliary information includes first information and second information, third indication information is sent to the terminal device according to the capability indicated by the second information.

[0287] As a possible implementation method, if the auxiliary information includes the first information, third indication information is sent to the terminal device according to the first capability information, and the third indication information is used to instruct the network device to configure the capability indicated by the first capability information for the terminal device.

[0288] Optionally, in S752, the network device proactively identifies service requirements, determines an updated working mode, and sends a third indication message to the terminal device.

[0289] Specifically, the network device proactively identifies current service model requirements (such as short-latency service requirements) and determines new uplink transmission capabilities to configure for the terminal device.
