[0001] This application relates to the field of communication technology, and more specifically, to a communication method, terminal equipment, and network equipment. Background Technology

[0002] Multi-carrier aggregation technology supports simultaneous data transmission and reception across multiple frequency bands. Terminal devices require multiple transceiver systems to support this technology, leading to increased complexity and power consumption. Furthermore, multi-carrier aggregation places high demands on filters; for adjacent frequency bands, the filtering effect is poor, preventing carrier aggregation of some frequency band combinations.

[0026] Figure 1 is a system architecture example diagram of a wireless communication system 100 to which embodiments of this application can be applied. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 may provide communication coverage for a specific geographical area and may communicate with the terminal device 120 located within that coverage area.

[0027] Figure 1 illustrates an exemplary network device and two terminal devices. Optionally, the wireless communication system 100 may include multiple network devices, and each network device may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

[0028] Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in this embodiment.

[0030] The terminal device in this application embodiment can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The terminal device in this application embodiment can be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects, and machines, such as a handheld device with wireless connectivity, vehicle-mounted device, etc. The terminal devices in the embodiments of this application can be mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, self-driving, remote medical surgery, smart grids, transportation safety, smart cities, and smart homes, etc. Optionally, the UE can act as a base station. For example, the UE can act as a scheduling entity, providing sidelink signals between UEs in V2X or D2D, etc. For example, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0031] The network device in this application embodiment can be a device for communicating with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network. A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master MeNB, auxiliary SeNB, multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar, or a combination thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. Base stations can also be mobile switching centers, devices that perform base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, network-side devices in 6G networks, and devices that perform base station functions in future communication systems. Base stations can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment.

[0032] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0033] In some deployments, the network device in this application embodiment may refer to a CU or a DU, or the network device may include both a CU and a DU. The gNB may also include an AAU.

[0034] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0035] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0036] Carrier aggregation (CA) is a technique that increases the bandwidth and data transmission rate of a communication system by aggregating multiple component carriers (CCs). CA technology allows terminal devices to transmit data simultaneously on multiple carriers, thus overcoming the bandwidth limitations of a single carrier. Multi-carrier aggregation supports simultaneous transmission and reception of data across multiple frequency bands. Terminal devices require multiple transceiver systems to support multi-carrier aggregation, leading to increased complexity and power consumption. Furthermore, multi-carrier aggregation places high demands on filters; for adjacent frequency bands, the filtering effect is poor, preventing carrier aggregation of some frequency band combinations.

[0037] To address the aforementioned issues, this application proposes that, when a terminal device is configured with a frequency domain unit combination, during the non-operating time of the first frequency domain unit in the frequency domain unit combination, the terminal device does not or does not expect to receive and / or transmit data in the first frequency domain unit. In this way, when the terminal device is configured with a frequency domain unit combination, the simultaneous transmission and reception of data by each frequency domain unit in the combination will be reduced or even avoided, thereby helping to reduce the complexity and power consumption of the terminal device.

[0038] The method embodiments of this application will be described below.

[0039] Figure 2 is a schematic flowchart of a communication method provided in an embodiment of this application. The method shown in Figure 2 can be executed by a terminal device. This terminal device can be, for example, the terminal device 120 shown in Figure 1. The method shown in Figure 2 includes step S220. This step will be described below.

[0040] In step S220, during the non-working time of the first frequency domain unit in the configured frequency domain unit combination, the terminal device determines that it will not receive and / or transmit data in the first frequency domain unit, or the terminal device does not expect to receive and / or transmit data in the first frequency domain unit.

[0041] This application does not limit the frequency domain units in the frequency domain unit combination. In some embodiments, the frequency domain units in the frequency domain unit combination are the basic frequency domain range for scheduling. Exemplarily, the frequency domain units in the frequency domain unit combination may include one or more of the following: carrier, frequency band, and a portion of the frequency domain resources within the carrier.

[0042] As an example, the frequency domain units in a frequency domain unit combination can be carriers. In this case, the frequency domain unit combination can also be called or understood as a carrier combination, which can include multiple carriers.

[0043] As another example, the frequency domain unit in a combination of frequency domain units can be a frequency band.

[0044] As yet another example, the frequency domain units in a combination of frequency domain units can be a portion of the frequency domain resources within the carrier.

[0045] As another example, the frequency domain units in a combination of frequency domain units can be frequency domain units composed of multiple non-contiguous carriers.

[0046] As yet another example, the frequency domain units in a frequency domain unit combination are all the frequency domain units contained in a cell.

[0047] As yet another example, the frequency domain units in a combination of frequency domain units can be multiple frequency bands.

[0048] In some embodiments, signals within a frequency domain unit can share the same radio frequency (RF). In other words, signals within a frequency domain unit are time-frequency synchronized.

[0049] This application does not limit the configuration method of frequency domain unit combinations. For example, a frequency domain unit combination can be any frequency domain unit combination configured in the network device. As another example, a frequency domain unit combination can be any frequency domain unit combination predefined by the protocol.

[0050] In some embodiments, a combination of frequency domain elements may include multiple (i.e., two or more) frequency domain elements. For example, a combination of frequency domain elements may include two frequency domain elements. As another example, a combination of frequency domain elements may include four frequency domain elements.

[0051] In the embodiments of this application, the first frequency domain unit can be any frequency domain unit in the combination of frequency domain units, and the embodiments of this application are not limited in this regard.

[0052] In some embodiments, the frequency domain unit combination may include a second frequency domain unit in addition to the first frequency domain unit. The second frequency domain unit may be any other frequency domain unit in the frequency domain unit combination besides the first frequency domain unit.

[0053] In some embodiments, the first frequency domain unit and the second frequency domain unit can be different types of frequency domain units. For example, the first frequency domain unit can be a frequency division duplex (FDD) band, and the second frequency domain unit can be a supplementary downlink (SDL) band.

[0054] In some embodiments, the operating times of the first frequency domain unit and the second frequency domain unit do not overlap. That is, when the first frequency domain unit is in its operating time, the second frequency domain unit is in its non-operating time; and / or, when the second frequency domain unit is in its operating time, the first frequency domain unit is in its non-operating time.

[0055] In some embodiments, when the first frequency domain unit is in a non-operating period, the second frequency domain unit may be in a non-operating period or in an operating period.

[0056] In some embodiments, the operating times of the frequency domain units in a frequency domain unit combination do not overlap. That is, at any given time location, only one frequency domain unit in the combination is in its operating time, while the others are in their non-operating time. As one implementation, when configuring a frequency domain unit combination, it can be configured so that only one frequency domain unit in the combination is in its operating time at a given time location. In some embodiments, this technique can also be called or understood as a switching technique for multiple frequency domain units in a frequency domain unit combination. Switching between multiple frequency domain units in a frequency domain unit combination helps avoid concurrent data transmission on those multiple frequency domain units, thereby reducing the complexity and power consumption of the terminal device. Furthermore, switching between multiple frequency domain units in a frequency domain unit combination helps to fully utilize frequency domain resources that cannot be aggregated.

[0057] In other words, when a terminal device is configured with a frequency domain unit combination (or at least two frequency domain units), or when a frequency domain unit combination is activated, the frequency domain units in that combination cannot be in working time (or cannot transmit data simultaneously). In other words, at a given time location, the terminal device can be in working time (or transmit data) on at most one frequency domain unit in that combination.

[0058] In some embodiments, when the first frequency domain unit is not in operation, it cannot be used to transmit and / or receive data. That is, the first frequency domain unit can only be used to transmit and / or receive data when it is in operation.

[0059] As one implementation, during the non-operating time of the first frequency domain unit, the terminal device determines not to receive and / or transmit data in the first frequency domain unit. That is, during the non-operating time of the first frequency domain unit, even if the network device schedules the terminal device to receive and / or transmit data in the first frequency domain unit, the terminal device will not actually receive and / or transmit data in the first frequency domain unit.

[0060] For example, if a network device sends data to a terminal device during the non-operating time of the first frequency domain unit, the terminal device determines that it will not receive the data in the first frequency domain unit. In this case, the terminal device can receive the data in a frequency domain unit that is operating during the operating time in the frequency domain unit combination.

[0061] For example, if a terminal device needs to send data to a network device during the non-operating time of the first frequency domain unit, the terminal device will determine not to send the data in the first frequency domain unit. In this case, the terminal device can send the data in a frequency domain unit that is operating during the working time in the frequency domain unit combination.

[0062] As another implementation, during the non-operating time of the first frequency domain unit, the terminal device does not expect to receive and / or transmit data in the first frequency domain unit. That is, during the non-operating time of the first frequency domain unit, the terminal device does not expect (does not want) the network device to schedule the terminal device to receive and / or transmit data in the first frequency domain unit. Correspondingly, during the non-operating time of the first frequency domain unit, the network device determines not to receive and / or transmit data from the terminal device in the first frequency domain unit. Therefore, in some embodiments, when the terminal device is configured with a combination of frequency domain units, the network device can determine the non-operating time of the first frequency domain unit in the combination. In this way, during the non-operating time of the first frequency domain unit, the network device determines not to receive and / or transmit data from the terminal device in the first frequency domain unit.

[0063] It should be noted that if the terminal device determines that it will not receive and / or transmit data in the first frequency domain unit during its non-operating time, the network device may not need to determine the non-operating time of the first frequency domain unit or not receive and / or transmit data from the terminal device in the first frequency domain unit. In other words, the network device can normally send data to the terminal device or schedule the terminal device to send data, but the terminal device itself can determine that it will not receive and / or transmit data in the first frequency domain unit.

[0064] When a terminal device is configured with a frequency domain unit combination, during the non-operating time of the first frequency domain unit in the combination, the terminal device does not receive or expects to receive and / or transmit data in the first frequency domain unit. In this way, when a terminal device is configured with a frequency domain unit combination, the simultaneous transmission and reception of data by each frequency domain unit in the combination is reduced or even avoided, thereby helping to reduce the complexity and power consumption of the terminal device.

[0065] In some embodiments, prior to step S220, the method of this application embodiment further includes step S210. In step S210, when the terminal device is configured with a frequency domain unit combination, the terminal device determines the non-operating time of the first frequency domain unit in the frequency domain unit combination.

[0066] This application does not limit the method by which the terminal device determines the non-working time of the first frequency domain unit. As one possible implementation, the terminal device can determine the non-working time of the first frequency domain unit based on the time-domain configuration information of the frequency domain unit combination. A description of the time-domain configuration information of the frequency domain unit combination can be found below and will not be detailed here. As another possible implementation, the terminal device can determine the non-working time of the first frequency domain time-domain unit based on instructions from the network device.

[0067] In some embodiments, the method of this application includes: during the operating time of a first frequency domain unit, the terminal device receives and / or transmits data only in the first frequency domain unit of the frequency domain unit combination. For example, when the operating times of the various frequency domain units in the frequency domain unit combination do not overlap, the terminal device receives and / or transmits data only in the first frequency domain unit of the frequency domain unit combination during the operating time of the first frequency domain unit. This helps avoid concurrent data transmission on various frequency domain units in the frequency domain unit combination, which not only helps reduce the complexity and power consumption of the terminal device, but also makes full use of frequency domain resources that cannot be aggregated.

[0068] In some embodiments, the method of this application includes: during the operating time of a first frequency domain unit, the terminal device does not expect other frequency domain units in the frequency domain unit combination besides the first frequency domain unit to receive and / or transmit data; or, the terminal device does not receive and / or transmit data in other frequency domain units in the frequency domain unit combination besides the first frequency domain unit. For example, when the operating times of the frequency domain units in the frequency domain unit combination do not overlap, during the operating time of the first frequency domain unit, the terminal device does not expect other frequency domain units in the frequency domain unit combination besides the first frequency domain unit to receive and / or transmit data; or, the terminal device does not receive and / or transmit data in other frequency domain units in the frequency domain unit combination besides the first frequency domain unit.

[0069] As mentioned above, the non-operating time of the first frequency domain unit can be determined based on the time-domain configuration information of the frequency domain unit combination. The time-domain configuration information of the frequency domain unit combination (hereinafter referred to as time-domain configuration information) is described below. It should be noted that the name of the time-domain configuration information is not limited in this application embodiment, as long as the configuration information is used to indicate the time-domain configuration of the frequency domain unit combination. For example, the time-domain configuration information can also be called or replaced with other terms such as time-domain configuration, configuration information of the frequency domain unit combination, etc.

[0070] This application does not limit the content of the time-domain configuration information. For example, the time-domain configuration information may include first information and / or second information. For instance, the time-domain configuration information may include first information. Or, for instance, the time-domain configuration information may include second information. Or, for instance, the time-domain configuration information may include both first and second information.

[0071] In some embodiments, the first information can be used to indicate the operating time of the frequency domain units in the frequency domain unit combination. That is, the first information can be used to indicate at which time domain positions the frequency domain units in the frequency domain unit combination operate.

[0072] The embodiments of this application do not limit the way the first information indicates the working time of the frequency domain units in the frequency domain unit combination, as long as the working time of the frequency domain units in the frequency domain unit combination can be determined according to the first information.

[0073] As one possible implementation, the first information can indicate the operating time of a frequency domain unit by indicating the switching pattern of the frequency domain units in the frequency domain unit combination. Therefore, in some embodiments, the first information can also be called or understood as frequency domain unit switching pattern information. Taking a frequency domain unit combination that includes a first frequency domain unit (identified by 0) and a second frequency domain unit (identified by 1) as an example, assuming the first information is [1111110000], it means that the second frequency domain unit is in operation during the first 6 time slots, and the first frequency domain unit is in operation during the last 4 time slots.

[0074] As another possible implementation, the first information may include indication information such as "the first frequency domain unit is in operation during time slots 6 to 9; the second frequency domain unit is in operation during time slots 0 to 5".

[0075] This application does not limit the method for determining (or obtaining) the first information. For example, the first information may be determined based on one or more of the following: semi-static configuration information, dynamic indication information, and protocol predefined information.

[0076] In some embodiments, the first information may be determined based on one of the above. For example, the first information may be determined based on semi-static configuration information. Another example is that the first information may be determined based on dynamic indication information. Yet another example is that the first information may be determined based on protocol predefined information.

[0077] In some embodiments, the first information can be determined based on multiple methods described above. For example, the first information can be determined based on semi-static configuration information and dynamic indication information. Another example is that the first information can be determined based on semi-static configuration information and protocol predefined information. Yet another example is that the first information can be determined based on dynamic indication information and protocol predefined information. Still another example is that the first information can be determined based on semi-static configuration information, dynamic indication information, and protocol predefined information.

[0078] In some embodiments, the second information may be used to indicate a first time interval required for switching between frequency domain units in a frequency domain unit combination. Therefore, in some embodiments, the second information may also be referred to as or understood as frequency domain unit switching interval information, frequency domain unit switching information, etc.

[0079] In some embodiments, the second information used to indicate the first time interval required for switching between frequency domain units in the frequency domain unit combination may refer to the second information indicating the duration and / or time-domain position of the first time interval required for switching between frequency domain units in the frequency domain unit combination. For example, the second information may indicate the duration of the first time interval required for switching between frequency domain units in the frequency domain unit combination. Another example is that the second information may indicate the time-domain position of the first time interval required for switching between frequency domain units in the frequency domain unit combination. Yet another example is that the second information may indicate both the duration and time-domain position of the first time interval required for switching between frequency domain units in the frequency domain unit combination.

[0080] In some embodiments, the first time interval (i.e., the first time interval required for switching between frequency domain units in a frequency domain unit combination) is the same for different terminal devices. For example, the first time interval is the same for terminal devices of different types or with different capabilities.

[0081] In other embodiments, the first time interval may differ for different terminal devices. For example, the first time interval may differ for terminal devices of different types or with different capabilities.

[0082] In some implementations, the terminal device can report its capability information. In this case, the first time interval required for switching between frequency domain units in the frequency domain unit combination can be determined based on the capability information reported by the terminal device.

[0083] This application does not limit the method for determining (or obtaining) the second information. For example, the second information may be determined based on one or more of the following: semi-static configuration information, dynamic indication information, and protocol predefined information.

[0084] In some embodiments, the second information may be determined based on one of the above. For example, the second information may be determined based on semi-static configuration information. Another example is that the second information may be determined based on dynamic indication information. Yet another example is that the second information may be determined based on protocol predefined information.

[0085] In some embodiments, the first information can be determined based on multiple methods described above. For example, the first information can be determined based on semi-static configuration information and dynamic indication information. Another example is that the first information can be determined based on semi-static configuration information and protocol predefined information. Yet another example is that the first information can be determined based on dynamic indication information and protocol predefined information. Still another example is that the first information can be determined based on semi-static configuration information, dynamic indication information, and protocol predefined information.

[0086] In some embodiments, the operating time and / or non-operating time of the first frequency domain unit are determined based on the first information described above. For example, the operating time of the first frequency domain unit may be the operating time of the first frequency domain unit indicated by the first information. As another example, the non-operating time of the first frequency domain unit may be the operating time of other frequency domain units in the combination of frequency domain units indicated by the first information, excluding the first frequency domain unit.

[0087] In some embodiments, the operating time and / or non-operating time of the first frequency domain unit are determined based on the first information and the second information described above. For example, the operating time of the first frequency domain unit can be a time outside the first time interval indicated by the second information within the operating time of the first frequency domain unit indicated by the first information. As another example, the non-operating time of the first frequency domain unit can be the operating time of other frequency domain units in the combination of frequency domain units indicated by the first information, excluding the first frequency domain unit, and / or the time corresponding to the first time interval required for switching between frequency domain units (i.e., the first time interval indicated by the second information).

[0088] In other words, in some embodiments, the terminal device can determine the entire non-operating time of the first frequency domain unit based on the first information. For example, the entire non-operating time of the first frequency domain unit is the operating time of the other frequency domain units in the frequency domain unit combination indicated by the first information, excluding the first frequency domain unit. In other embodiments, the terminal device can determine a portion of the non-operating time of the first frequency domain unit based on the first information, where the portion of the non-operating time is the operating time of the other frequency domain units in the frequency domain unit combination indicated by the first information, excluding the first frequency domain unit. In this case, the other non-operating time of the first frequency domain unit can be determined based on second information; for example, the other non-operating time of the first frequency domain unit may include the time corresponding to the first time interval required for switching between frequency domain units.

[0089] In some embodiments, the length of the first time interval is less than or equal to the length of the second time interval. Alternatively, the terminal device expects the length of the second time interval to be greater than or equal to the length of the first time interval; that is, the terminal device does not expect the length of the second time interval to be less than the length of the first time interval. The second time interval is the time interval between the end time of the first data transmission and the start time of the second data transmission.

[0090] In some embodiments, the first data is the last data transmitted before performing a frequency domain unit switch (i.e., switching between frequency domain units in a frequency domain unit combination), and the second data is the first data transmitted after performing a frequency domain unit switch.

[0091] In some embodiments, if the length of the second time interval is less than the length of the first time interval, the terminal device may discard the data received and / or sent within the first time interval.

[0092] In some embodiments, if the length of the second time interval is less than the length of the first time interval, the terminal device can discard data received and / or transmitted within the first time interval according to the frequency domain configuration corresponding to the first time interval. For example, if the length of the second time interval is less than the length of the first time interval, the terminal device can discard data within the first time interval on the frequency domain units configured in the first time interval, that is, the terminal device can discard data on the frequency domain units configured (or active) in the first time interval.

[0093] This application does not limit the term "data" as used herein. For example, "data" as used herein may include one or more of the following: broadcast data, semi-statically configured data, and dynamically scheduled data.

[0094] For example, during the non-operating time of the first frequency domain unit, if the terminal device determines that it will not receive and / or transmit data in the first frequency domain unit, or if the terminal device does not expect to receive and / or transmit data in the first frequency domain unit, it may include: during the non-operating time of the first frequency domain unit, the terminal device determines that it will not receive and / or transmit one or more of the following in the first frequency domain unit: broadcast data, semi-statically configured data, dynamically scheduled data; or, the terminal device does not expect to receive and / or transmit one or more of the following in the first frequency domain unit: broadcast data, semi-statically configured data, dynamically scheduled data.

[0095] As an example, during the non-operating time of the first frequency domain unit, the terminal device determines that it will not receive and / or transmit broadcast data, semi-statically configured data, and dynamically scheduled data in the first frequency domain unit; or, the terminal device does not expect to receive and / or transmit broadcast data, semi-statically configured data, and dynamically scheduled data in the first frequency domain unit. In other words, during the non-operating time of the first frequency domain unit, the terminal device determines that it will not receive and / or transmit all data in the first frequency domain unit, or, the terminal device does not expect to receive and / or transmit all data in the first frequency domain unit. This approach simplifies the processing of the terminal device and makes implementation simpler.

[0096] As another example, during the non-operating hours of the first frequency domain unit, the terminal device determines that it will not receive and / or transmit dynamically scheduled data in the first frequency domain unit; or, the terminal device does not expect to receive and / or transmit dynamically scheduled data in the first frequency domain unit. This approach helps to reasonably avoid scheduling and / or transmission conflicts.

[0097] As another example, during the non-operating time of the first frequency domain unit, the terminal device determines that it will not receive and / or transmit semi-static configuration data in the first frequency domain unit; or, the terminal device does not expect to receive and / or transmit semi-static configuration data in the first frequency domain unit. Using this approach, the terminal device only needs to support a single channel or a small number of channels, which simplifies the implementation of the terminal device.

[0098] As yet another example, during the non-working time of the first frequency domain unit, the terminal device determines that it will not receive and / or transmit semi-statically configured data and dynamically scheduled data in the first frequency domain unit; or, the terminal device does not expect to receive and / or transmit semi-statically configured data and dynamically scheduled data in the first frequency domain unit.

[0099] For example, during the operating time of the first frequency domain unit, the terminal device may receive and / or transmit data only in the first frequency domain unit of the combination of frequency domain units. This may include receiving and / or transmitting one or more of the following only in the first frequency domain unit of the combination of frequency domain units: broadcast data, semi-statically configured data, and dynamically scheduled data.

[0100] As an example, during the operating time of the first frequency domain unit, the terminal device receives and / or transmits broadcast data, semi-statically configured data, and dynamically scheduled data only in the first frequency domain unit of the frequency domain unit combination.

[0101] As another example, during the operating time of the first frequency domain unit, the terminal device receives and / or transmits dynamically scheduled data only in the first frequency domain unit of the combination of frequency domain units.

[0102] As yet another example, during the operating time of the first frequency domain unit, the terminal device receives and / or transmits semi-statically configured data only in the first frequency domain unit of the combination of frequency domain units.

[0103] As yet another example, during the operating time of the first frequency domain unit, the terminal device receives and / or transmits semi-statically configured data and dynamically scheduled data only in the first frequency domain unit of the combination of frequency domain units.

[0104] For example, during the operating time of the first frequency domain unit, the terminal device does not expect to receive and / or transmit data in (or not in) other frequency domain units in the combination of frequency domain units other than the first frequency domain unit. This may include: during the operating time of the first frequency domain unit, the terminal device does not expect to receive and / or transmit one or more of the following in (or not in) other frequency domain units in the combination of frequency domain units other than the first frequency domain unit: broadcast data, semi-statically configured data, dynamically scheduled data.

[0105] As an example, during the operating time of the first frequency domain unit, the terminal device does not expect to receive and / or transmit broadcast data, semi-statically configured data, and dynamically scheduled data in (or not in) other frequency domain units in that frequency domain unit combination besides the first frequency domain unit.

[0106] As another example, during the operating time of the first frequency domain unit, the terminal device does not expect to receive and / or transmit dynamically scheduled data in (or not in) other frequency domain units in that combination of frequency domain units besides the first frequency domain unit.

[0107] As yet another example, during the operating time of the first frequency domain unit, the terminal device does not expect to receive and / or transmit semi-statically configured data in (or not in) other frequency domain units in that combination of frequency domain units besides the first frequency domain unit.

[0108] As yet another example, during the operating time of the first frequency domain unit, the terminal device does not expect to receive and / or transmit semi-statically configured data and dynamically scheduled data in (or not in) other frequency domain units in that frequency domain unit combination besides the first frequency domain unit.

[0109] In some embodiments, the term "data" as used in this application includes one of the above-described categories. For example, "data" as used in this application includes dynamically scheduled data. As another example, "data" as used in this application includes semi-statically configured data.

[0111] It should be noted that the broadcast data mentioned in the embodiments of this application refers to public data, and is not limited to data transmitted through a broadcast channel. For example, the broadcast data mentioned in the embodiments of this application may include data from a broadcast channel and / or synchronization signals. In some embodiments, broadcast data may also be referred to or replaced by other terms such as always-on data, public data, public signals, periodically transmitted data, etc.

[0112] In some embodiments, the data for the semi-static configuration described above may include semi-static configuration and / or semi-persistent activation data.

[0113] This application does not limit the type of "data" mentioned herein. For example, "data" may include one or more of the following: downlink data channel, downlink reference signal, synchronization signal block, broadcast channel, synchronization signal, downlink control channel, uplink data channel, uplink reference signal, random access channel, and uplink control channel.

[0114] In some embodiments, the term "data" as used herein includes any of the foregoing. For example, "data" as used herein includes a downlink data channel. As another example, "data" as used herein includes a broadcast channel. As yet another example, "data" as used herein includes a synchronization signal block.

[0115] In some embodiments, the term "data" as used in this application includes multiple terms mentioned above.

As another example, the term "data" as used in this application includes a downlink data channel, a downlink control channel, an uplink data channel, and an uplink control channel.

[0116] It should be noted that the above examples are merely illustrations, and the "data" mentioned in this application may include any one or more of the above. For the sake of brevity, they will not be listed one by one here.

[0117] It should also be noted that the embodiments of this application do not limit the data to include only those listed above. For example, the data may also include new data types or new channels introduced by future communication systems.

[0118] In some embodiments, the downlink data channel may include, for example, a physical downlink shared channel (PDSCH), or a channel in a future communication system that has the same or similar function as a PDSCH.

[0119] In some embodiments, the downlink reference signal may include, for example, a channel state information (CSI) reference signal (CSI-RS), or a signal in a future communication system that has the same or similar function as CSI-RS.

[0120] In some embodiments, the downlink control channel may include, for example, a physical downlink control channel (PDCCH), or a channel in a future communication system that has the same or similar function as the PDCCH.

[0121] In some embodiments, the uplink data channel may include, for example, a physical uplink shared channel (PUSCH), or a channel in a future communication system that has the same or similar function as a PUSCH.

[0122] In some embodiments, the uplink reference signal may include, for example, a sounding reference signal (SRS), or a signal in a future communication system that has the same or similar function as an SRS.

[0123] In some embodiments, the random access channel may include, for example, a physical random access channel (PRACH), or a channel in a future communication system that has the same or similar function as PRACH.

[0124] In some embodiments, the uplink control channel may include, for example, a physical uplink control channel (PUCCH), or a channel in a future communication system that has the same or similar function as a PUCCH.

[0125] In some embodiments, the method of this application includes: if the transmission time of third data to be received and / or transmitted by the terminal device on the first frequency domain unit overlaps with the non-working time of the first frequency domain unit, the terminal device may perform one of the following operations: stop receiving and / or transmitting the third data, cancel the reception and / or transmission of the third data, or discard the third data.

[0126] In some embodiments, the transmission time of the third data to be received and / or transmitted by the terminal device on the first frequency domain unit overlaps with the non-working time of the first frequency domain unit, which may include one of the following: the transmission time of the third data to be received and / or transmitted by the terminal device on the first frequency domain unit partially overlaps with the non-working time of the first frequency domain unit, or the transmission time of the third data to be received and / or transmitted by the terminal device on the first frequency domain unit completely overlaps with the non-working time of the first frequency domain unit.

[0127] In some embodiments, the transmission time of the third data to be received and / or transmitted by the terminal device on the first frequency domain unit overlaps with the non-working time of the first frequency domain unit, which may include: the transmission time of the third data to be received and / or transmitted by the terminal device on the first frequency domain unit overlaps with the time corresponding to the first time interval required for switching between frequency domain units.

[0128] In some embodiments, the transmission time of the third data to be received and / or sent by the terminal device on the first frequency domain unit overlaps with the non-working time of the first frequency domain unit, which may include: the transmission time of the third data to be received and / or sent by the terminal device on the first frequency domain unit overlaps with the working time of other frequency domain units in the frequency domain unit combination indicated by the first information, excluding the first frequency domain unit.

[0129] In some embodiments, the transmission time of the third data to be received and / or sent by the terminal device on the first frequency domain unit overlaps with the non-working time of the first frequency domain unit. This may include: the transmission time of the third data to be received and / or sent by the terminal device on the first frequency domain unit overlaps with the time corresponding to the first time interval required for switching between frequency domain units, and overlaps with the working time of other frequency domain units in the frequency domain unit combination indicated by the first information, excluding the first frequency domain unit.

[0130] In some embodiments, the third data is dynamically scheduled data. In this case, if the transmission time of the third data on the first frequency domain unit overlaps with the non-working time of the first frequency domain unit, the terminal device may stop / cancel the reception and / or transmission of the third data, or discard the third data.

[0131] In some embodiments, the third data is semi-statically configured data. In this case, if the transmission time of the third data on the first frequency domain unit overlaps with the non-operating time of the first frequency domain unit, the terminal device may stop / cancel the reception and / or transmission of the third data, or discard the third data.

[0132] In some embodiments, the third data is network device scheduling data. Alternatively, the third data is direct data for network device scheduling / configuration; that is, the third data is network device scheduling / configuration data that has not been processed. Therefore, in some embodiments, the third data may also be referred to as or understood as raw data, unprocessed data, etc.

[0133] Taking the third data as an example, which is semi-static configuration data and network device scheduling data (i.e. unprocessed data), as shown in Figure 3, if the third data overlaps with the non-working time of the first frequency domain unit (such as the time corresponding to the first time interval required for switching between frequency domain units), the terminal device will stop / cancel the reception and / or transmission of the third data, or discard the third data.

[0134] In other embodiments, the third data is determined after processing multiple data scheduled by the network device. In these cases, the transmission times of the multiple data scheduled by the network device overlap (e.g., partially or completely), therefore, the multiple data need to be processed to obtain the third data.

[0135] This application does not limit the implementation method of how to process multiple data with overlapping transmission times to obtain third data. For example, the above processing may include one or more of the following: multiple data with overlapping transmission times are multiplexed and transmitted on one channel, and some data among the multiple data are discarded based on the priority of the multiple data with overlapping transmission times.

[0136] As an example, the third data is the data determined after multiple data scheduled by the network device are multiplexed and transmitted on a single channel.

[0137] As another example, the third data is determined after discarding a portion of the data from multiple data sets based on the priority of network device scheduling.

[0138] As yet another example, the third data is based on the priority of multiple data sets scheduled by network devices, discarding some of the data from these multiple data sets, and multiplexing the remaining data into the data determined after transmission over a single channel.

[0139] In some embodiments, when a terminal device multiplexes multiple data with overlapping transmission times into one channel for transmission, the multiplexed channel can be a new channel or one of the channels to which the overlapping data belongs (i.e., overlapping channels).

[0140] Taking the example of the third data being semi-statically configured data, and the third data being determined after processing multiple data scheduled by the network device, as shown in Figure 4, the uplink semi-static channel 1 overlaps with the non-working time of the first frequency domain unit (such as the time corresponding to the first time interval required for switching between frequency domain units), and there is also overlap between uplink semi-static channel 1 and channel 2. In this case, the terminal device can first process the data of uplink semi-static channel 1 and channel 2 according to preset rules to obtain the third data. Subsequently, if the processed third data overlaps with the non-working time of the first frequency domain unit (such as the time corresponding to the first time interval required for switching between frequency domain units), the terminal device stops / cancels the reception and / or transmission of the third data, or discards the third data.

[0141] In some embodiments, the terminal device processes the data from uplink semi-static channels 1 and 2, which may include: the terminal device multiplexing the data from uplink semi-static channels 1 and 2 into a single channel for transmission. The multiplexed channel may be a new channel, or it may be uplink semi-static channel 1 or channel 2.

[0142] In some embodiments, the terminal device processes the data of uplink semi-static channel 1 and channel 2, which may include: the terminal device discarding one of the uplink semi-static channels 1 and 2 based on priority.

[0143] In some embodiments, uplink semi-static channel 1 can be used for semi-static configuration data. For example, uplink semi-static channel 1 can be used for semi-static feedback, such as a PUCCH for HARQ-ACK feedback in semi-static scheduling. As another example, uplink semi-static channel 1 can be used for periodic CSI reporting, such as a PUCCH for periodic CSI reporting. Yet another example, uplink semi-static channel 1 can be used for configured grants.

[0144] In some embodiments, channel 2 may be an uplink semi-static channel. In some embodiments, channel 2 may be a dynamic channel. For example, channel 2 may be a channel used for dynamic HARQ-ACK feedback.

[0145] In some embodiments, the synchronization signals and / or broadcast channels on different frequency domain units in the frequency domain unit combination of this application have different time domain positions. For example, the synchronization signal blocks on different frequency domain units in the frequency domain unit combination have different time domain positions.

[0146] In other words, in some embodiments, the terminal device does not expect the synchronization signals and / or broadcast channels on the frequency domain units in the same frequency domain unit combination to be configured in the same time domain position.

[0147] In some embodiments, the aforementioned time-domain location may include time slots and / or symbols. For example, different time-domain locations corresponding to synchronization signals and / or broadcast channels on different frequency domain units may include: different time slots corresponding to synchronization signals and / or broadcast channels on different frequency domain units, and / or different symbols corresponding to synchronization signals and / or broadcast channels on different frequency domain units. As another example, the terminal device does not expect the synchronization signals and / or broadcast channels on frequency domain units within the same frequency domain unit combination to have the same time-domain location configuration may include: the terminal device does not expect the synchronization signals and / or broadcast channels on frequency domain units within the same frequency domain unit combination to have the same time slot configuration, and / or the terminal device does not expect the synchronization signals and / or broadcast channels on frequency domain units within the same frequency domain unit combination to have the same symbol configuration. However, the embodiments of this application are not limited to this; for example, the aforementioned time-domain location may include other time-domain units such as subframes.

[0148] For example, different time-domain positions corresponding to synchronization signals and / or broadcast channels on different frequency domain units can include different time slots corresponding to synchronization signals and / or broadcast channels on different frequency domain units. Different time slots corresponding to synchronization signals and / or broadcast channels on different frequency domain units help avoid frequency domain unit switching within time slots, simplifying implementation. Taking a frequency domain unit combination including a first frequency domain unit and a second frequency domain unit as an example, referring to Figure 5, the time slot positions of the synchronization signals and / or broadcast channels configured in the first frequency domain unit are different from those configured in the second frequency domain unit. It should be noted that in the example of Figure 5, the symbol positions of the synchronization signals and / or broadcast channels configured in the first frequency domain unit and the second frequency domain unit can be the same or different.

[0149] For example, the different time-domain positions of synchronization signals and / or broadcast channels on different frequency domain units can include different symbols for the synchronization signals and / or broadcast channels on different frequency domain units. Different symbols for synchronization signals and / or broadcast channels on different frequency domain units provide more options for the configuration positions of synchronization signals and / or broadcast channels, enabling a combination of frequency domain units to include more frequency domain units. Taking a combination of frequency domain units including a first frequency domain unit and a second frequency domain unit as an example, referring to Figure 6, the symbol positions of the synchronization signals and / or broadcast channels configured in the first frequency domain unit are different from those configured in the second frequency domain unit.

[0150] For example, the different time domain positions of synchronization signals and / or broadcast channels on different frequency domain units may include: the time slots and symbols corresponding to synchronization signals and / or broadcast channels on different frequency domain units are different.

[0151] It should be noted that in Figures 5 and 6, one square represents one time slot.

[0152] The methods for terminal devices have been introduced above. The methods for network devices will be introduced below.

[0153] Figure 7 is a schematic flowchart of a communication method provided in another embodiment of this application. The method shown in Figure 7 can be executed by a network device. This network device can be, for example, the network device 110 shown in Figure 1. The method shown in Figure 7 includes step S720.

[0154] In step S720, during the non-working time of the first frequency domain unit in the frequency domain unit combination configured for the terminal device, the network device determines not to receive and / or transmit data from the terminal device in the first frequency domain unit.

[0155] In some embodiments, prior to step S720, the method of this application embodiment further includes step S710. In step S710, when the terminal device is configured with a frequency domain unit combination, the network device determines the non-operating time of the first frequency domain unit in the frequency domain unit combination.

[0156] In some embodiments, the above-described frequency domain unit combination further includes a second frequency domain unit, wherein the operating times of the first frequency domain unit and the second frequency domain unit do not overlap.

[0157] In some embodiments, the non-operating time of the first frequency domain unit is determined based on the time-domain configuration information of the frequency domain unit combination, which includes one or more of the following: first information for indicating the operating time of the frequency domain units in the frequency domain unit combination; and second information for indicating the first time interval required for switching between the frequency domain units in the frequency domain unit combination.

[0158] In some embodiments, the operating time of the first frequency domain unit is one of the following: the operating time of the first frequency domain unit indicated by the first information; or, the time in the operating time of the first frequency domain unit indicated by the first information that is outside the first time interval.

[0159] In some embodiments, the non-operating time of the first frequency domain unit includes one or more of the following: the operating time of other frequency domain units in the frequency domain unit combination indicated by the first information, excluding the first frequency domain unit; and the time corresponding to the first time interval.

[0160] In some embodiments, the method of this application further includes: during the operating time of the first frequency domain unit, the network device receives and / or transmits data from the terminal device only in the first frequency domain unit of the frequency domain unit combination.

[0161] It should be noted that the network-side details not described in detail (such as data, time-domain configuration information, first information, second information, etc.) can be found in the above description, and will not be repeated here for the sake of brevity.

[0162] For ease of understanding, the following description uses a combination of frequency domain units including a first frequency domain unit (such as FDD band n29A) and a second frequency domain unit (such as SDL band n5A) as an example, and combines several embodiments to exemplify this application. It should be noted that the embodiments described below are not intended to limit the solution of this application.

[0163] Example 1:

[0164] When the terminal device determines that the first frequency domain unit is in working time based on the time domain configuration information of the frequency domain unit combination, the terminal device does not expect to receive and / or transmit data on the second frequency domain unit. Alternatively, when the terminal device determines that the first frequency domain unit is in working time based on the time domain configuration information of the frequency domain unit combination, the terminal device only receives and / or transmits data on the first frequency domain unit. Or, when the terminal device determines that the second frequency domain unit is in non-working time based on the time domain configuration information of the frequency domain unit combination, the terminal device does not expect to receive and / or transmit data on the second frequency domain unit. The first and second frequency domain units are configured in a frequency domain unit switching mode.

[0165] The data mentioned above includes data on dynamic scheduling, as well as data on semi-static configuration and / or semi-persistent activation.

[0166] The aforementioned data includes one or more of the following: downlink data channel, downlink reference signal, synchronization signal block, broadcast channel, synchronization signal, downlink control channel, uplink data channel, uplink reference signal, random access channel, and uplink control channel.

[0167] It should be noted that the way the terminal device determines the operating status of the first frequency domain unit and / or the second frequency domain unit based on the time domain configuration information of the frequency domain unit combination is not limited to the examples below, especially the signaling details. For example, the terminal device can determine, based on the first information [1111110000], that the first frequency domain unit is in a non-operating time and the second frequency domain unit is in an operating time during the first 6 time slots of a radio frame; and that the first frequency domain unit is in an operating time and the second frequency domain unit is in a non-operating time during the last 4 time slots of the radio frame. Here, "0" in the first information represents the first frequency domain unit, and "1" represents the second frequency domain unit.

[0168] Furthermore, the terminal device can also use the second information to determine the operating status of the first frequency domain unit and / or the second frequency domain unit. For example, based on protocol predefined information and / or network configuration, the terminal device determines that the switching interval between the first and second frequency domain units is in the last two symbols of the sixth time slot. Then, the terminal device determines that the second frequency domain unit is in operating time during the first five time slots and the first twelve symbols of the sixth time slot of the radio frame, and is not in operating time during the other times; and that the first frequency domain unit is in operating time during the last four time slots of the radio frame, and is not in operating time during the other times.

[0169] In the scheme of Example 1, the processing of the terminal device is simple.

[0170] Example 2:

[0171] When the terminal device determines that the first frequency domain unit is in working time based on the time domain configuration information of the frequency domain unit combination, the terminal device does not expect to receive and / or send dynamically scheduled data on the second frequency domain unit. Alternatively, when the terminal device determines that the first frequency domain unit is in working time based on the time domain configuration information of the frequency domain unit combination, the terminal device only receives and / or sends dynamically scheduled data on the first frequency domain unit. Or, when the terminal device determines that the second frequency domain unit is in non-working time based on the time domain configuration information of the frequency domain unit combination, the terminal device does not expect to receive and / or send dynamically scheduled data on the second frequency domain unit. The first and second frequency domain units are configured in a frequency domain unit switching mode.

[0172] The aforementioned data includes one or more of the following: downlink data channel, downlink reference signal, synchronization signal block, broadcast channel, synchronization signal, downlink control channel, uplink data channel, uplink reference signal, random access channel, and uplink control channel.

[0173] It should be noted that the way the terminal device determines the operating status of the first frequency domain unit and / or the second frequency domain unit based on the time domain configuration information of the frequency domain unit combination is not limited to the examples below, especially the signaling details. For example, the terminal device can determine, based on the first information [1111110000], that the first frequency domain unit is in a non-operating time and the second frequency domain unit is in an operating time during the first 6 time slots of a radio frame; and that the first frequency domain unit is in an operating time and the second frequency domain unit is in a non-operating time during the last 4 time slots of the radio frame. Here, "0" in the first information represents the first frequency domain unit, and "1" represents the second frequency domain unit.

[0174] Furthermore, the terminal device can also use the second information to determine the operating status of the first frequency domain unit and / or the second frequency domain unit. For example, based on protocol predefined information and / or network configuration, the terminal device determines that the switching interval between the first and second frequency domain units is in the last two symbols of the sixth time slot. Then, the terminal device determines that the second frequency domain unit is in operating time during the first five time slots and the first twelve symbols of the sixth time slot of the radio frame, and is not in operating time during the other times; and that the first frequency domain unit is in operating time during the last four time slots of the radio frame, and is not in operating time during the other times.

[0175] The solution in Example 2 helps to reasonably avoid data transmission conflicts.

[0176] Example 3:

[0177] When the terminal device determines that the first frequency domain unit is in a non-working time based on the time domain configuration information of the frequency domain unit combination, the terminal device will not receive and / or transmit semi-static configuration and / or semi-persistent activation data during the non-working time of the first frequency domain unit. Alternatively, the terminal device will stop / cancel / discard receiving and / or transmitting semi-static configuration and / or semi-persistent activation data that overlaps (partially or completely) with the non-working time.

[0178] In some embodiments, when the semi-static configuration and / or semi-persistently active data overlaps with other data (partial or complete overlap), the terminal device first handles the data conflicts, and then determines the transmission mode of the processed data based on the time-domain configuration information of the frequency domain unit combination. Specific determination methods can be found in the examples of Figure 3 or Figure 4.

[0179] It should be noted that the way the terminal device determines the operating status of the first frequency domain unit and / or the second frequency domain unit based on the time domain configuration information of the frequency domain unit combination is not limited to the examples below, especially the signaling details. For example, the terminal device can determine, based on the first information [1111110000], that the first frequency domain unit is in a non-operating time and the second frequency domain unit is in an operating time during the first 6 time slots of a radio frame; and that the first frequency domain unit is in an operating time and the second frequency domain unit is in a non-operating time during the last 4 time slots of the radio frame. Here, "0" in the first information represents the first frequency domain unit, and "1" represents the second frequency domain unit.

[0180] Furthermore, the terminal device can also use the second information to determine the operating status of the first frequency domain unit and / or the second frequency domain unit. For example, based on protocol predefined information and / or network configuration, the terminal device determines that the switching interval between the first and second frequency domain units is in the last two symbols of the sixth time slot. Then, the terminal device determines that the second frequency domain unit is in operating time during the first five time slots and the first twelve symbols of the sixth time slot of the radio frame, and is not in operating time during the other times; and that the first frequency domain unit is in operating time during the last four time slots of the radio frame, and is not in operating time during the other times.

[0181] In the scheme of Example 3, the terminal device may support only a single channel or support fewer channels, which helps to simplify the implementation of the terminal device.

[0182] Example 4:

[0183] Terminal devices do not expect synchronization signal blocks on different frequency units within the same frequency unit combination to be configured with the same time-domain location, including identical time slots and symbols. In other words, terminal devices expect synchronization signal blocks on different frequency units within the same frequency unit combination to be configured with different time-domain locations, including different time slots and / or symbols. The configuration of the time-domain locations of synchronization signal blocks on different frequency units within the same frequency unit combination can be seen in the examples in Figure 5 or Figure 6.

[0184] The method embodiments of this application have been described in detail above with reference to Figures 1 to 7. The apparatus embodiments of this application will be described in detail below with reference to Figures 8 to 10.
