Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method, a communication device, a terminal device, and a network device. Background Art

[0002] For a wireless communication system operating in the time division duplexing (TDD) mode, the downlink carrier and the uplink carrier of the system are carriers with the same carrier frequency. In the new radio interface (NR) technology of the 5th generation (5G) mobile communication system, the uplink-downlink decoupling technology can be applied, that is, in addition to using a TDD carrier with a frequency of F1 (which can also be called an unpaired carrier) for uplink and downlink communication, the network device can also use an additional uplink carrier for uplink communication. This additional uplink carrier is usually called a supplementary uplink (SUL).

[0003] When the SUL is set, one antenna of the terminal device is shared by the uplink carrier and the two frequency bands of the SUL. Since an antenna can only be set to one operating frequency within a period of time, the terminal device needs to switch between the two frequencies. Currently, when the terminal device performs frequency switching, the base station is not aware of this, and the terminal device does not notify the base station. Therefore, when the base station schedules the terminal device, it does not know which frequency the terminal device is currently operating on, which may lead to unreasonable scheduling of the terminal device. Summary of the Invention

[0004] Embodiments of this application provide a communication method, a communication device, a terminal device, and a network device, which can be used to schedule the terminal device more reasonably.

[0005] In a first aspect, a first communication method is provided. The method includes: receiving a first signaling from a network device, where the first signaling is used to indicate sending a first uplink signal to the network device on a first uplink carrier, and the first signaling also indicates a first frequency; and setting an operating frequency according to the first frequency.

[0006] The method in the first aspect can be executed by a first communication device. The first communication device can be a communication device or a communication device that can support the communication device to implement the functions required by the method, such as a chip system. Further, the communication device can be a terminal device. In the following introduction process, the communication device is taken as an example of a terminal device for effect analysis.

[0007] In an embodiment of the present application, the terminal device may set the operating frequency of the terminal device according to the first frequency indicated by the network device, so that the network device and the terminal device have the same understanding of the operating frequency of the terminal device, which facilitates the efficient communication between the terminal device and the network device. For example, when the network device schedules the terminal device, it can clearly know the current operating frequency of the terminal device, so that when the network device schedules, it can determine whether to instruct the terminal device to switch the operating frequency, realizing better scheduling of the terminal device by the network device.

[0008] Combined with the first aspect, in a possible implementation manner of the first aspect, setting the operating frequency according to the first frequency includes:

[0009] After sending the first uplink signal, setting the operating frequency according to the first frequency; or,

[0010] Before the end of the first time period corresponding to the first uplink signal, setting the operating frequency according to the first frequency, where the first time period is the time domain resource for sending the first uplink signal; or,

[0011] Before the end moment of the time unit where the first uplink signal is located, setting the operating frequency according to the first frequency.

[0012] Which of the above methods the terminal device uses to set the operating frequency can be indicated by the network device. For example, the first signaling indicates one of the above methods, or it can also be specified by the protocol, in which case no indication from the network device is required.

[0013] Combined with the first aspect, in a possible implementation manner of the first aspect, the first frequency corresponds to the first uplink carrier; or, the first frequency corresponds to the second uplink carrier.

[0014] If the first frequency corresponds to the first uplink carrier, then the frequency at which the terminal device sends the first uplink signal to the network device is also the first frequency. Then, when the terminal device sets the operating frequency of the terminal device according to the first frequency, it actually maintains the operating frequency of the terminal device unchanged at the first frequency. Or, if the first frequency corresponds to the second uplink carrier, then the frequency at which the terminal device sends the first uplink signal to the network device is not the first frequency. Then, when the terminal device sets the operating frequency of the terminal device according to the first frequency, it is to switch the operating frequency from the frequency corresponding to the first uplink carrier to the first frequency.

[0015] In combination with the first aspect, in a possible implementation manner of the first aspect, the method further includes: receiving a second signaling from the network device, where the second signaling instructs to send a second uplink signal to the network device on the first uplink carrier, where the second uplink signal is within the same time unit as the first uplink signal and the second uplink signal is after the first uplink signal.

[0016] The network device may schedule the terminal device to send the first uplink signal and the second uplink signal.

[0017] In combination with the first aspect, in a possible implementation manner of the first aspect,

[0018] After sending the first uplink signal on the first uplink carrier, setting the operating frequency to the first frequency includes: after sending the first uplink signal and the second uplink signal, setting the operating frequency according to the first frequency; or,

[0019] Before the end moment of the time unit where the first uplink signal is located, setting the operating frequency to the first frequency includes: after sending the first uplink signal and the second uplink signal, and before the end moment of the time unit where the first uplink signal is located, setting the operating frequency according to the first frequency.

[0020] When the terminal device receives the first signaling and the second signaling, the terminal device can continue to set the operating frequency according to the first signaling. Then, after the terminal device sends the first uplink signal and the second uplink signal, it can set the operating frequency of the terminal device according to the first frequency. For example, it can set the operating frequency after both the first uplink signal and the second uplink signal are sent, so that the process of setting the operating frequency does not affect the sending process of the first uplink signal and the second uplink signal as much as possible. Or, after the terminal device sends the first uplink signal and the second uplink signal, and before the end moment of the time unit where the first uplink signal is located, it can set the operating frequency of the terminal device according to the first frequency, which can ensure that the terminal device does not set the operating frequency a long time after sending the first uplink signal and the second uplink signal, so that the terminal device can set the operating frequency in a more timely manner. Or, the terminal device can set the operating frequency of the terminal device according to the first frequency after sending the first uplink signal. In this case, if the first frequency is not the frequency corresponding to the first uplink carrier, then, if the terminal device sets the operating frequency to the frequency corresponding to the first uplink carrier again after setting according to the first frequency, and the time-domain resources corresponding to the second uplink signal have not expired or have not all expired, the terminal device can still send all or part of the second uplink signal. However, if the terminal device does not set the operating frequency to the frequency corresponding to the first uplink carrier again after setting according to the first frequency, or, if the terminal device sets the operating frequency to the frequency corresponding to the first uplink carrier again after setting according to the first frequency, but the time-domain resources corresponding to the second uplink signal have all expired, the terminal device cannot send the second uplink signal.

[0021] Or, when the terminal device receives the first signaling and the second signaling, the terminal device can also set the operating frequency according to the indication of the second signaling. For example, if the second signaling indicates the second frequency, the terminal device can set the operating frequency according to the second frequency. For example, after the terminal device sends the first uplink signal and the second uplink signal, it can set the operating frequency of the terminal device according to the second frequency. For example, it can set the operating frequency after both the first uplink signal and the second uplink signal are sent, so that the process of setting the operating frequency does not affect the sending process of the first uplink signal and the second uplink signal as much as possible. Or, after the terminal device sends the first uplink signal and the second uplink signal, and before the end moment of the time unit where the first uplink signal is located, it can set the operating frequency of the terminal device according to the second frequency, which can ensure that the terminal device does not set the operating frequency a long time after sending the first uplink signal and the second uplink signal, so that the terminal device can set the operating frequency in a more timely manner.

[0022] In a second aspect, a second communication method is provided. The method includes: sending a first signaling to a terminal device, where the first signaling is used to instruct the terminal device to send a first uplink signal to a network device on a first uplink carrier, and the first signaling further indicates a first frequency.

[0027] Before the end moment of the time unit where the first uplink signal is located arrives, the terminal device sets the operating frequency according to the first frequency.

[0033] In the embodiments of this application, the terminal device can set the operating frequency according to a first condition, and the network device can also know that the terminal device will set the operating frequency according to the first condition, so that the network device can determine the operating frequency of the terminal device. For example, when the network device schedules the terminal device, it can determine whether to reserve time for the terminal device to set the operating frequency, so as to reduce the probability of the terminal device discarding signals and improve the signal transmission quality.

The terminal device can include a user equipment (UE), a wireless terminal device, a mobile terminal device, a device-to-device (D2D) communication terminal device, a vehicle-to-everything (V2X) terminal device, a machine-to-machine / machine-type communications (M2M / MTC) terminal device, an Internet of Things (IoT) terminal device, a subscriber unit, a subscriber station, a mobile station, a remote station, an access point (AP), a remote terminal, an access terminal, a user terminal, a user agent, or a user device, etc. For example, it can include a mobile phone (or a so-called "cellular" phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, or computer-integrated mobile device, etc. For example, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. It also includes restricted devices, such as devices with lower power consumption, or devices with limited storage capacity, or devices with limited computing power, etc. For example, it includes information sensing devices such as barcodes, radio frequency identification (RFID), sensors, global positioning system (GPS), laser scanners, etc.

[0257] By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. A wearable device, also known as a wearable intelligent device or a smart wearable device, etc., is a general term for devices developed by applying wearable technology to the intelligent design of daily wear, such as glasses, gloves, watches, clothing, shoes, etc. A wearable device is a portable device that is directly worn on the body or integrated into the user's clothes or accessories. A wearable device is not just a hardware device, but also realizes powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable intelligent devices include those with complete functions and large sizes that can achieve complete or partial functions without relying on a smart phone. For example:

[0258] Smart watches or smart glasses, etc., and those that only focus on a certain type of application function and need to cooperate with other devices such as smart phones, such as various smart bracelets for vital sign monitoring, smart helmets, smart jewelry, etc.

[0259] And for the various terminal devices introduced above, if they are located on a vehicle (for example, placed inside or installed inside a vehicle), they can all be considered in-vehicle terminal devices. An in-vehicle terminal device, for example, is also referred to as an on-board unit (OBU).

[0260] In the embodiments of the present application, the terminal device may also include a relay. Or, it can be understood that anything capable of data communication with a base station can be regarded as a terminal device.

[0261] 2) Network devices, for example, including access network (AN) devices, such as base stations (for example, access points), which may refer to devices in the access network that communicate with wireless terminal devices through one or more cells over the air interface. Or, for example, in a vehicle-to-everything (V2X) technology, the network device is a roadside unit (RSU). A base station can be used to mutually convert received airframes and IP packets and act as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network. An RSU can be a fixed infrastructure entity that supports V2X applications and can exchange messages with other entities that support V2X applications. The network device can also coordinate the management of the attributes of the air interface. For example, the network device may include an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in a long term evolution (LTE) system or a long term evolution-advanced (LTE-A) system, or may also include a fifth-generation mobile communication technology (the 5th In a new radio (NR) system (also simply referred to as an NR system) of the next generation node B (gNB) in the (5G) new air interface or it may also include a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (Cloud RAN) system. The embodiments of the present application do not limit this.

[0262] The receiving device described in the embodiments of the present application may be a terminal device or may also be a network device. Similarly, the sending device for sending data packets in the embodiments of the present application may be a terminal device or a network device. And, for example, in one case, the sending device is a network device and the receiving device is a terminal device, or in another case, both the sending device and the receiving device are network devices, or in yet another case, both the sending device and the receiving device are terminal devices, etc., and no specific limitation is made.

[0263] 3) Multi-RAT dual connectivity (MR-DC). In the LTE system, a terminal device supports simultaneous access to two network devices, and this access mode is called dual connectivity (DC), where one network device is the primary network device and the other network device is the secondary network device. In the development and evolution process of a wireless communication system, an operator will deploy both a 5G NR system and an LTE system at the same time, and the terminal device also supports simultaneous access to an LTE network device and an NR network device. Since LTE is also called evolved universal terrestrial radio access (E-UTRA), this access mode is called E-UTRA NR dual connectivity (EN-DC). In the EN-DC mode, the LTE network device is the primary network device and the NR network device is the secondary network device. Of course, with the evolution of the system, in the future, it may also support NR E-UTRA dual connectivity (NE-DC), that is, the NR network device is the primary network device and the LTE network device is the secondary network device. Since the terminal devices in EN-DC and NE-DC will access network devices of two different radio access technologies, these DC modes can also be collectively referred to as MR-DC.

[0264] 4) Subcarrier spacing: In an OFDM system, it is the spacing value between the center positions or peak positions of two adjacent subcarriers in the frequency domain. For example, the subcarrier spacing in the LTE system is 15 kHz, and the subcarrier spacing in the NR system of 5G can be 15 kHz, or 30 kHz, or 60 kHz, or 120 kHz, etc.

[0265] 5) Time slot: In the NR system, one time slot includes 14 OFDM symbols. For example, the time slot length corresponding to a 15 kHz subcarrier spacing is 1 ms, and the time slot length corresponding to a 30 kHz subcarrier spacing is 0.5 ms.

[0266] 6) In the embodiments of the present application, the terms "system" and "network" can be used interchangeably. "At least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c can be single or multiple.

[0267] Moreover, unless otherwise stated, the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects and are not used to limit the order, time sequence, priority, or importance of multiple objects. For example, the first data packet and the second data packet are only used to distinguish different data packets, rather than indicating differences in the content, priority, transmission order, or importance of these two data packets.

[0268] Some noun concepts related to the embodiments of the present application are introduced above. Next, the technical features involved in the embodiments of the present application are introduced.

[0269] For a wireless communication system operating in TDD mode, the downlink carrier and the uplink carrier of the system are carriers with the same carrier frequency. In the NR technology of the 5G system, uplink-downlink decoupling technology can be applied, that is, in addition to using a TDD carrier with a frequency of F1 (which can also be called an unpaired carrier) for uplink and downlink communication, the network device can also use an additional uplink carrier for uplink communication. This additional uplink carrier is usually called SUL, and the carrier frequency F2 of SUL is less than F1. That is, the network device / terminal device of NR can have two uplink carriers for uplink communication at the same time, and these two uplink carriers correspond to one downlink carrier. For reference Figure 1 , a typical scenario is that the NR TDD carrier frequency is in the 3.5 GHz band, and the SUL frequency is in the 1.8 GHz band. Figure 1 In, the time slot marked as D is the downlink time slot, and the time slot marked as U is the uplink time slot, and in Figure 1 In the example of, the subcarrier spacing on the NR TDD carrier is greater than the subcarrier spacing on the SUL, so that the length of the first time slot on the NR TDD carrier is less than the length of the second time slot on the SUL. Usually, the subcarrier spacing on the NR TDD carrier is 30 KHz, and the subcarrier spacing on the SUL is 15 KHz, so that the time length of the first time slot on the NR TDD carrier is half of the time length of the second time slot on the SUL. It should be noted that this SUL can be a carrier independently used by the NR system or an uplink carrier shared by the NR system and the LTE system.

[0270] For the above-mentioned MR-DC and terminal devices supporting SUL, usually only 2 transmit antennas are configured. One transmit antenna is allocated to the frequency of 3.5 GHz, and the other transmit antenna can be time-division shared by the frequencies of 1.8 GHz and 3.5 GHz. In this way, the terminal can use two antennas to transmit at the frequency of 3.5 GHz. Compared with transmitting with only 1 antenna, the uplink rate and capacity can be improved.

[0271] Considering that one antenna of the terminal device will be shared by the frequencies of 1.8 GHz and 3.5 GHz, and at the same time, one antenna can only be set at one operating frequency within a period of time, the terminal device needs to switch between the two frequencies. When the terminal device switches one antenna between the two frequencies, for example, when the terminal device switches from the TDD carrier of 3.5 GHz to the SUL of 1.8 GHz, the terminal device needs a certain conversion time to adjust the operating frequency of this antenna from 3.5 GHz to 1.8 GHz. This process usually takes 20 microseconds.

[0272] Currently, the operating frequency of the antenna of a terminal device depends on the implementation of the terminal device, and the network device does not know the operating frequency of the antenna of the terminal device. Then, when the antenna of the terminal device is at a certain operating frequency, the network device may instruct the terminal device to send an uplink signal at another frequency. At this time, the terminal device needs to switch the operating frequency of the antenna. Since the terminal device requires a certain conversion time when switching the operating frequency of the antenna, when the terminal device switches between two frequencies, it generally discards the signal carried on the last symbol of the previous carrier or discards the signal carried on the first symbol of the next carrier, so that the terminal device can complete the adjustment of the operating frequency of the radio frequency circuit during the time occupied by the symbol with the discarded signal. For example, refer to Figure 2 , when the terminal device needs to switch from the frequency for sending the physical uplink control channel (PUCCH) to another frequency to send the physical uplink shared channel (PUSCH), the terminal device uses the time occupied by the first symbol of the time slot occupied by the PUSCH as the conversion time.

[0273] It can be seen that in the current frequency switching scheme, the terminal device generally needs to discard the corresponding signal for switching. Since the network device does not know the operating frequency of the antenna of the terminal device, the network device will not know that the terminal device has discarded some signals, which may cause problems in subsequent configuration or scheduling of the terminal device by the network device. Moreover, since the network device cannot know the operating frequency of the antenna of the terminal device, the terminal device may discard some signals when the network device schedules the terminal device. Obviously, this scheduling method is not reasonable enough.

[0274] In view of this, the technical solution of the embodiments of the present application is provided. In the embodiments of the present application, the terminal device can set the operating frequency of the terminal device according to the first frequency indicated by the network device, so that the network device can clearly know the operating frequency of the terminal device. When scheduling the terminal device, it can determine whether to instruct the terminal device to switch the operating frequency. By this method, the network device can clearly know the current operating frequency of the terminal device, so that the network device can better schedule the terminal device.

[0275] A scenario to which the embodiments of the present application are applied is that the terminal device operates in the LTE and NR dual-connection mode, where the terminal device is simultaneously connected to the LTE network device and the NR network device. It should be noted that the LTE network device and the NR network device can be deployed at the same site, such as Figure 3 and Figure 4 shown. Among them, Figure 3It is a schematic diagram of the hardware structure of network devices and terminal devices. Alternatively, LTE network devices and NR network devices can also be deployed at different sites, such as Figure 5 and Figure 6 shown. Among them, Figure 5 It is a schematic diagram of the hardware structure of network devices and terminal devices. And when LTE network devices and NR network devices are deployed at the same site, the LTE network devices and NR network devices can share the same set of hardware devices, such as Figure 4 shown, which is a schematic diagram of the LTE network device and the NR network device sharing some hardware devices. Figure 4 In , the LTE network device and the NR network device can share a transceiver. Alternatively, when LTE network devices and NR network devices are deployed at the same site, the LTE network devices and NR network devices can also use different hardware devices respectively.

[0276] The technical solutions provided by the embodiments of the present application will be described below with reference to the accompanying drawings. In the embodiments of the present application, for example, 2 or more transmit antennas are configured for the terminal device, and 1 of the transmit antennas needs to be shared by two frequencies or more frequencies. For example, 2 transmit antennas are configured for the terminal device, 1 of the transmit antennas is allocated to the frequency of 3.5 GHz, and the other transmit antenna can be time-division shared by the frequencies of 1.8 GHz and 3.5 GHz. Then, for this transmit antenna that needs to perform frequency sharing, it can operate on at least two uplink carriers, but at a certain moment, this transmit antenna can only operate on one of the at least two uplink carriers.

[0277] It should be noted that the operating frequency in the embodiments of the present application can be understood as the operating frequency of the terminal device. This operating frequency can be the operating frequency of the transmit antenna of the terminal device, or the operating frequency of the radio frequency link of the terminal device. Generally speaking, this operating frequency can be the frequency related to the signal transmitted by the terminal device, such as called Tx frequency.

[0278] The operating frequency in the embodiments of the present application can also be understood as a frequency range, that is to say, the terminal device can operate within this frequency range. This frequency range can correspond to the frequency band defined in the protocol, or correspond to the frequency range occupied by a carrier bandwidth, or correspond to the operating frequency of the bandwidth part in a carrier. Taking the case where this frequency range corresponds to a carrier bandwidth as an example, this frequency range can be equal to the frequency range occupied by this carrier bandwidth, or can be greater than the frequency range occupied by this carrier bandwidth, which is not limited here.

[0279] In various embodiments of the present application, taking the execution by a terminal device as an example of the corresponding method, the "operating frequency" is described as the "operating frequency of the terminal device" hereinafter. If the method is executed by other devices, such as a chip system, then the described operating frequency should refer to the operating frequency of the chip system. In short, as the execution entity changes, the object corresponding to the operating frequency also changes accordingly.

[0280] The embodiments of the present application provide a first communication method. Please refer to Figure 7 , which is a flowchart of the method. In the following introduction process, the method is applied to Figures 3 - 6 any network architecture shown in any of the drawings as an example. In addition, the method can be executed by two communication devices, such as a first communication device and a second communication device. Among them, the first communication device can be a network device or a communication device that can support the network device to implement the functions required for the method, or the first communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required for the method. Of course, it can also be other communication devices, such as a chip system. The second communication device can be a network device or a communication device that can support the network device to implement the functions required for the method, or the second communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required for the method. Of course, it can also be other communication devices, such as a chip system. And there are no restrictions on the implementation manners of the first communication device and the second communication device. For example, the first communication device can be a network device, the second communication device is a terminal device, or the first communication device and the second communication device are both network devices, or the first communication device and the second communication device are both terminal devices, or the first communication device is a network device, and the second communication device is a chip system that can support the terminal device to implement the functions required for the method, and so on. Among them, the network device is, for example, a base station.

[0281] For the convenience of introduction, hereinafter, taking the execution of the method by a network device and a terminal device as an example, that is, taking the first communication device as a terminal device and the second communication device as a network device as an example. If the embodiments of the present application are applied to Figures 3 - 6 any network architecture shown in any of the drawings, then the terminal device described hereinafter can be Figures 3 - 6 the terminal device in any network architecture shown in any of the drawings. In addition, the network device described hereinafter can be Figures 3 - 6 an LTE network device or an NR network device in any network architecture shown in any of the drawings.

[0282] S71. The network device sends a first signaling to the terminal device, and the terminal device receives the first signaling from the network device. The first signaling is used to instruct to send a first uplink signal to the network device on a first uplink carrier, and the first signaling also instructs a first frequency.

[0283] In an embodiment of the present application, for example, two or more transmit antennas are configured for a terminal device. One of the transmit antennas can operate on at least two uplink carriers. However, at a given moment, the transmit antenna can only operate on one of the at least two uplink carriers. The at least two uplink carriers include a first uplink carrier, which can be, for example, a normal uplink carrier or can also be SUL. The at least two uplink carriers can include an uplink carrier of NR and an uplink carrier of LTE, or the at least two uplink carriers include uplink carriers of two different cells, and there is no specific limitation.

[0284] The first signaling is, for example, downlink control information (DCI), or can also be other types of information, such as high-layer signaling. Among them, the high-layer signaling is, for example, radio resource control (RRC) signaling or media access control (MAC) layer signaling, etc.

[0285] Taking the first signaling being DCI as an example, this DCI is originally used to schedule the terminal device to send an uplink signal to the network device on the first uplink carrier. For example, the uplink signal scheduled by this DCI is called the first uplink signal. For example, the first uplink signal can be one of PUSCH, PUCCH, physical-layer random access channel (PRACH), or sounding reference signal (SRS).

[0286] As an alternative, in addition to scheduling the first uplink signal, the first signaling can also instruct the terminal device to set the operating frequency according to the first method. Equivalently, the network device can instruct the terminal device on how to set the operating frequency, so that the terminal device can set it according to the instruction of the network device. In this way, the network device can know the operating frequency of the terminal device to perform a more reasonable scheduling on the terminal device. In addition, the first signaling can also indicate a first frequency, and the terminal device needs to set the operating frequency of the terminal device according to the first frequency. This can be understood as the first frequency being the target frequency that the terminal device needs to set. That is to say, after the terminal device sets the operating frequency, the operating frequency of the terminal device needs to be the first frequency. Or it can also be described as the terminal device needs to set the operating frequency according to the first frequency, or described as the terminal device needs to set the first frequency as the operating frequency. For example, the terminal device sets the operating frequency according to the first method and the first frequency.

[0287] The terminal device sets its operating frequency according to the first frequency, which may be setting the operating frequency to the first frequency. Before setting the operating frequency to the first frequency, the operating frequency of the terminal device may be the first frequency, or it may be other frequencies, such as the second frequency. For example, if the first frequency is the frequency corresponding to the first uplink carrier, then before the terminal device sets its operating frequency in the first manner, the operating frequency of the terminal device is the first frequency. In this case, when the terminal device sets its operating frequency, it can be considered that the terminal device maintains its operating frequency at the first frequency. Or, if the first frequency is not the frequency corresponding to the first uplink carrier but the frequency corresponding to the second uplink carrier supported by the terminal device, then before the terminal device sets its operating frequency in the first manner, the operating frequency of the terminal device is not the second frequency. In this case, when the terminal device sets its operating frequency, it can be considered that the terminal device switches its operating frequency from other frequencies to the first frequency.

[0288] Regarding the first manner, it may include a first sub-manner, a second sub-manner, or a third sub-manner, or it may also include other sub-manners. The first sub-manner, the second sub-manner, and the third sub-manner will be introduced separately below.

[0289] 1. First sub-manner: After sending the first uplink signal on the first uplink carrier, set the operating frequency of the terminal device. Then, combined with the first frequency indicated by the first signaling, the terminal device sets its operating frequency according to the first frequency.

[0290] In the first sub-manner, the first signaling instructs the terminal device to set its operating frequency after sending the first uplink signal. The terminal device can set its operating frequency after sending the first uplink signal. This can be understood as that the terminal device can set its operating frequency after the first uplink signal is sent. For example, the first signaling schedules the terminal device to send the first uplink signal on 14 orthogonal frequency division multiplexing (OFDM) symbols in a time slot. Then, the terminal device can set its operating frequency after sending the first uplink signal, such as in one or more OFDM symbols in the next time slot after this time slot. For example, the terminal device can use the time occupied by the first OFDM symbol in the next time slot to set its operating frequency. Or, for example, the first signaling schedules the terminal device to send the first uplink signal on the first 12 OFDM symbols in a time slot. Then, the terminal device can set its operating frequency after sending the first uplink signal, such as in the 13th OFDM symbol and / or the 14th OFDM symbol in this time slot. The number of OFDM symbols required for the terminal device to set its operating frequency is not limited in the embodiments of this application.

[0291] For example, the antenna of the terminal device can operate on a first uplink carrier corresponding to a frequency of 3.5 GHz and a second uplink carrier corresponding to a frequency of 1.8 GHz. The network device schedules the terminal device to send a first uplink signal to the network device on the first uplink carrier through a first signaling, and the first signaling indicates that after sending the first uplink signal, the terminal device needs to set its operating frequency according to a first frequency. Additionally, the first signaling also indicates the first frequency. According to the indication of the first signaling, after sending the first uplink signal, the terminal device can set its operating frequency according to the first frequency. For example, if the first frequency is 3.5 GHz, then it is equivalent to the operating frequency of the terminal device remaining unchanged. Thus, when the terminal device sets its operating frequency according to the first frequency, it can be understood that the terminal device continues to maintain its operating frequency at 3.5 GHz. Or, for example, if the first frequency is 1.8 GHz, then it is equivalent to the operating frequency of the terminal device changing. Thus, when the terminal device sets its operating frequency according to the first frequency, it can be understood that the terminal device switches its operating frequency from 3.5 GHz to 1.8 GHz.

[0292] Setting the operating frequency of the terminal device after sending the first uplink signal can ensure that the sending of the first uplink signal is not affected when the terminal device sets its operating frequency, avoid discarding the first uplink signal, and try to ensure that the first uplink signal can be sent normally.

[0293] 2. Second sub - method: Set the operating frequency of the terminal device before sending the first uplink signal is completed. Then, combined with the first frequency indicated by the first signaling, the terminal device sets its operating frequency according to the first frequency.

[0294] For example, the first signaling schedules the terminal device to send a first uplink signal in a first time period. Then, the first signaling can also indicate that before the end moment of the first time period arrives, set the operating frequency of the terminal device according to the first frequency. Or, the first signaling can indicate that before the end of the first time period, set the operating frequency of the terminal device according to the first frequency.

[0295] In the second sub-mode, the network device instructs the terminal device to set the operating frequency of the terminal device before the end of the first time period, and the first uplink signal needs to be sent on the first uplink carrier. That is to say, the first uplink signal needs to be sent on the operating frequency before the setting. Therefore, the terminal device cannot set the operating frequency of the terminal device before starting to send the first uplink signal, which will result in the inability to send the first uplink signal. In this case, the terminal device can choose to set the operating frequency of the terminal device when the first uplink signal is about to be sent (or when the first time period is about to end). The time difference between the moment when the terminal device starts to set the operating frequency and the end moment of the first time period can be related to the time set for the terminal device to set the operating frequency. For example, the time difference between the moment when the terminal device starts to set the operating frequency and the end moment of the first time period is greater than or equal to the time set for the terminal device to set the operating frequency, so that the terminal device can complete the setting of the operating frequency at the latest when the first time period ends.

[0296] For example, the first signaling schedules the terminal device to send the first uplink signal on 14 OFDM symbols of a time slot. Then the terminal device can set the operating frequency of the terminal device before sending the first uplink signal. For example, the terminal device sets the operating frequency of the terminal device within the last OFDM symbol of this time slot. In this case, the terminal device may need to discard all or part of the signals carried by the last OFDM symbol of this time slot. Whether to discard all or part of the signals carried by the last OFDM symbol of this time slot depends on the time required for the terminal device to complete the setting of the operating frequency. And the signal carried by the last OFDM symbol of this time slot is part of the first uplink signal. That is to say, the terminal device needs to discard part of the uplink signal to complete the setting of the operating frequency. However, in this case, since it is the network device that instructs the terminal device to set the operating frequency of the terminal device before sending the first uplink signal, and the first uplink signal is also scheduled by the network device, the network device can know that the terminal device will discard part of the first uplink signal. Therefore, the network device can have corresponding strategies to deal with it and can also complete tasks such as reasonably configuring the terminal device.

[0297] For example, the antenna of the terminal device can operate on a first uplink carrier corresponding to a frequency of 3.5 GHz and a second uplink carrier corresponding to a frequency of 1.8 GHz. The network device schedules the terminal device to send a first uplink signal to the network device on the first uplink carrier during a first time period through a first signaling, and the first signaling indicates that before the end of the first time period, the terminal device should set its operating frequency according to a first frequency, and in addition, the first signaling also indicates the first frequency. According to the indication of the first signaling, before the end of the first time period, the terminal device can set its operating frequency according to the first frequency. For example, if the first frequency is 3.5 GHz, it is equivalent that the operating frequency of the terminal device does not change, then when the terminal device sets its operating frequency according to the first frequency, it can be understood that the terminal device continues to maintain its operating frequency at 3.5 GHz. Or, for example, if the first frequency is 1.8 GHz, it is equivalent that the operating frequency of the terminal device needs to change, then when the terminal device sets its operating frequency according to the first frequency, it can be understood that the terminal device switches its operating frequency from 3.5 GHz to 1.8 GHz.

[0298] Setting the operating frequency of the terminal device before sending the first uplink signal completely can enable the terminal device to work on the set operating frequency as soon as possible. And for the discarding of some signals of the first uplink signal, the network device can know it, so the network device can also make corresponding decisions.

[0299] 3. The third sub - method: Set the operating frequency of the terminal device before the end moment of the time unit where the first uplink signal is located. Then, combined with the first frequency indicated by the first signaling, the terminal device sets its operating frequency according to the first frequency. The time difference between the moment when the terminal device starts to set the operating frequency and the end moment of the time unit where the first uplink signal is located can be related to the time set for the terminal device to set the operating frequency. For example, the time difference between the moment when the terminal device starts to set the operating frequency and the end moment of the time unit where the first uplink signal is located is greater than or equal to the time set for the terminal device to set the operating frequency, so that the terminal device can complete the setting of the operating frequency at the latest when the time unit where the first uplink signal is located ends.

[0300] In the third sub-mode, the network device instructs the terminal device to set the operating frequency of the terminal device before the end moment of the time unit where the first uplink signal is located. The first uplink signal needs to be transmitted on the first uplink carrier, that is to say, the first uplink signal needs to be transmitted on the operating frequency before the setting. Therefore, the terminal device cannot set the operating frequency of the terminal device before starting to transmit the first uplink signal, which will cause the first uplink signal to be unable to be transmitted. Taking the time unit as a time slot as an example, in this case, if the first uplink signal needs to be transmitted on the last symbol included in the time unit where the first uplink signal is located, then the terminal device can choose to set the operating frequency of the terminal device when the first uplink signal is about to be transmitted completely. Or, if the first uplink signal does not need to be transmitted on the last symbol included in the time unit where the first uplink signal is located, then the terminal device can choose to set the operating frequency of the terminal device after the first uplink signal is transmitted.

[0301] For example, the first signaling schedules the terminal device to transmit the first uplink signal on 14 OFDM symbols of a time slot. The terminal device needs to set the operating frequency of the terminal device before the end moment of the time unit where the first uplink signal is located. Then the terminal device can set the operating frequency of the terminal device before transmitting the first uplink signal completely. For example, the terminal device sets the operating frequency of the terminal device within the last OFDM symbol of this time slot. In this case, the terminal device may need to discard all or part of the signals carried by the last OFDM symbol of this time slot. Whether to discard all or part of the signals carried by the last OFDM symbol of this time slot depends on the time required for the terminal device to complete the setting of the operating frequency. And the signal carried by the last OFDM symbol of this time slot is part of the first uplink signal, that is to say, the terminal device needs to discard a part of the uplink signal to complete the setting of the operating frequency. However, in this case, because it is the network device that instructs the terminal device to set the operating frequency of the terminal device before the end moment of the time unit where the first uplink signal is located, and the first uplink signal is also scheduled by the network device, the network device can know that the terminal device will discard a part of the first uplink signal. Therefore, the network device can have corresponding strategies to deal with it and can also complete tasks such as more reasonably configuring the terminal device.

[0302] For another example, if the first signaling scheduling terminal device transmits a first uplink signal on the first 12 OFDM symbols in a time slot, and the terminal device needs to set the operating frequency of the terminal device before the end moment of the time unit where the first uplink signal is located, then the terminal device can set the operating frequency of the terminal device after transmitting the first uplink signal. For example, the operating frequency of the terminal device can be set on the 13th OFDM symbol and / or the 14th OFDM symbol of this time slot. In this case, the terminal device does not need to discard the first uplink signal, so that the first uplink signal can be transmitted as completely as possible, and it can also ensure that the operating frequency is set as timely as possible.

[0303] Which specific sub - mode of the first mode is included above can be configured by the network device or specified by the protocol. Among them, if the first mode is configured by the network device, the network device can indicate the first mode to the terminal device. For example, the first signaling also indicates that the terminal device sets the operating frequency of the terminal device according to the first mode; or, if the first mode is specified by the protocol, the network device does not need to indicate. After receiving the first signaling from the network device, the terminal device can set the operating frequency of the terminal device according to the first mode specified by the protocol. Of course, the first frequency used for setting is still indicated by the first signaling. In this case, it can be considered that the first frequency is used for the terminal device to set the operating frequency after transmitting the first uplink signal on the first uplink carrier, or, for the terminal device to set the operating frequency before the end moment of the time unit where the first uplink signal is located, or, for the terminal device to set the operating frequency before the end moment of the first time period.

[0304] It should be noted that in the first sub - mode, it can be understood that the first signaling instructs the terminal device to set the operating frequency of the terminal device after the first moment. In the first sub - mode, the first moment is the end moment of transmitting the first uplink signal. The first moment can also be other moments, such as a certain moment after the end moment of transmitting the first uplink signal, or the first moment can also be based on other moments, such as the end moment when the terminal device receives the first signaling or the signal carrying the first signaling. That is to say, the first signaling instructs the terminal device to set the operating frequency of the terminal device after adding a preset duration to the end moment when the terminal device receives the signal carrying the first signaling. The preset duration can be configured by the network device or can also be specified by the protocol. Similarly, in the second sub - mode or the third sub - mode, it can be understood that the first signaling instructs the terminal device to complete setting the operating frequency of the terminal device before the second moment. The second moment is not limited to the specific implementation methods in the second sub - mode and the third sub - mode. The second moment can also be other moments, such as a certain moment after the end moment of transmitting the first uplink signal. Additionally, the second moment can also be based on other moments, such as the end moment when the terminal device receives the first signaling or the signal carrying the first signaling. That is to say, the first signaling instructs the terminal device to complete setting the operating frequency of the terminal device before adding a preset duration to the end moment when the terminal device receives the signal carrying the first signaling.

[0305] For example, the first signaling may include indication information. Through the indication information, the terminal device can be instructed to set the operating frequency according to the first method. For example, the indication information occupies 1 bit (bit). If the value of this 1 - bit is "0", it means not to set the operating frequency of the antenna, that is, to maintain the current operating frequency of the antenna, that is, not to change the operating frequency of the antenna. If the value of this 1 - bit is "1", it means to set the operating frequency of the antenna, that is, to set the operating frequency of the antenna to another frequency. In this case, if the value of this 1 - bit is "1", the first signaling may also additionally indicate the first frequency, then the first signaling may also include one or more additional bits to indicate the first frequency.

[0306] Or, if the first signaling includes the indication information, it means to set the operating frequency of the antenna. If the first signaling does not include the indication information, it means not to set the operating frequency of the antenna. In this case, the value of the indication information can be arbitrary. In this case, if the value of this 1 - bit is "1", the first signaling may also additionally indicate the first frequency, then the first signaling may also include one or more additional bits to indicate the first frequency.

[0307] Alternatively, if one antenna of the terminal device for frequency sharing can operate on two uplink carriers, one of which is a high-frequency carrier and the other is a low-frequency carrier, then if the value of this 1 bit is "0", it means that the operating frequency of the terminal device is set to the frequency corresponding to the high-frequency carrier, which is equivalent to implicitly indicating that the first frequency is the frequency corresponding to the high-frequency carrier. And if the value of this 1 bit is "1", it means that the operating frequency of the terminal device is set to the frequency corresponding to the low-frequency carrier, which is equivalent to implicitly indicating that the first frequency is the frequency corresponding to the low-frequency carrier. Of course, the high frequency and low frequency here are only relative to each other. For example, if the antenna of the terminal device can operate on an uplink carrier of 1.8 GHz and an uplink carrier of 3.5 GHz, then 1.8 GHz is the low frequency relative to 3.5 GHz, and 3.5 GHz is the high frequency relative to 1.8 GHz. In this case, the first signaling does not need to use other bits to indicate the first frequency.

[0308] It should be noted that the indication information here can be explicitly included in the first signaling or implicitly included in the first signaling. For example, it can be implicitly included in other fields of the first signaling. In a possible implementation, the indication information is implicitly included in the first field of the first signaling for indicating the time resource occupied by the first uplink signal. The first field indicates the starting symbol position and length of the symbols occupied by the first uplink signal, and at the same time indicates that the terminal device sets its operating frequency in the first manner. When the first field has Y optional states, where Y is a positive integer greater than 1, X states correspond to setting the operating frequency of the antenna, and Y - X states correspond to not setting the operating frequency of the antenna. X is a positive integer greater than or equal to 1 and less than Y. Specifically, when the first field indicates that the symbols occupied by the first uplink signal do not include the last K symbols of the time slot where they are located, it indicates that the terminal device sets the operating frequency of the antenna; when the first field indicates that the symbols occupied by the first uplink signal include at least one of the last K symbols of the time slot where they are located, it indicates that the terminal device does not set the operating frequency of the antenna.

[0309] In another possible implementation, the indication information is carried in the scrambling code of the first signaling. For example, it is carried in the scrambling code of the downlink signal carrying the first signaling. Among them, when scrambling with the first scrambling code, it corresponds to setting the operating frequency of the antenna; when scrambling with the second scrambling code, it corresponds to not setting the operating frequency of the antenna. Here, the specific manner in which the indication information is carried in the first signaling is not limited.

[0310] S72. The terminal device sends a first uplink signal to the network device on the first uplink carrier, and the network device receives the first uplink signal from the terminal device on the first uplink carrier of the terminal device. That is to say, before setting the operating frequency according to the first frequency, the terminal device sends a first uplink signal to the network device on the first uplink carrier.

[0311] Since the first uplink signal needs to be sent at the operating frequency before the setting, the terminal device first sends the first uplink signal to the network device.

[0312] S73. The terminal device sets the operating frequency according to the first frequency. In Figure 7 it, taking the terminal device as an example, after sending the first uplink signal on the first uplink carrier, sets the operating frequency according to the first frequency, or before the end moment of the time unit where the first uplink signal is located, sets the operating frequency according to the first frequency.

[0313] After the terminal device sends the first uplink signal to the network device, the terminal device can set the operating frequency of the terminal device according to the first frequency. For example, the terminal device can set the operating frequency according to the first method and the first frequency. The specific first method can refer to the introduction in S71.

[0314] Previously, only the case where the terminal device receives the first signaling was considered. It is also possible that in addition to sending the first signaling to the terminal device, the network device also sends a second signaling to the terminal device. The second signaling instructs to send a second uplink signal to the network device on the first uplink carrier. After receiving the second signaling from the network device, the terminal device can determine to send the second uplink signal to the network device on the first uplink carrier. Among them, the second uplink signal is temporally after the first uplink signal, that is, the first uplink signal is sent first, the second uplink signal is sent later, and the first uplink signal and the second uplink signal are in the same time unit. For example, the time occupied by the first uplink signal and the second uplink signal in the same time unit does not overlap, and the time unit is, for example, a time slot.

[0315] The second signaling is, for example, DCI, or it can also be other types of information, such as high-layer signaling, etc. Among them, the high-layer signaling is, for example, RRC signaling or MAC layer signaling, etc. The second uplink signal is, for example, one of PUSCH, PUCCH, PRACH, or SRS.

[0316] The first signaling and the second signaling can be of the same type of signaling. For example, both are DCI, or both are high-layer signaling. In the case of both being high-layer signaling, the first signaling and the second signaling can both be RRC signaling or MAC layer signaling, or it is also possible that one is RRC signaling and the other is MAC layer signaling; or, the first signaling and the second signaling can also be of different types of signaling. For example, the first signaling is DCI and the second signaling is high-layer signaling, or the first signaling is high-layer signaling and the second signaling is DCI.

[0317] When considering the two signalings, different situations need to be distinguished.

[0318] In the first case, the second signaling does not instruct the terminal device to set the operating frequency. That is, the first signaling instructs the terminal device to set the operating frequency, while the second signaling does not instruct the terminal device to set the operating frequency.

[0319] In this case, the terminal device can set the operating frequency of the terminal device according to the instruction of the first signaling. Since both the first uplink signal and the second uplink signal need to be sent on the first uplink carrier, that is, both need to be sent on the operating frequency before the setting, then the terminal device can set the operating frequency of the terminal device according to the instruction of the first signaling after sending the first uplink signal and the second uplink signal. However, it is possible that the second uplink signal is sent after the first uplink signal is sent. Therefore, if this is the case, the network device can preferably choose to instruct the terminal device to set the operating frequency according to the first sub - mode or the third sub - mode. If the operating frequency is set according to the first sub - mode, then the terminal device can set the operating frequency of the terminal device after sending the first uplink signal and the second uplink signal; or, if the operating frequency is set according to the third sub - mode, then the terminal device can set the operating frequency of the terminal device before the end moment of the time unit where the first uplink signal is located. Since the first uplink signal and the second uplink signal are in the same time unit, the terminal device can set the operating frequency of the terminal device before the end of this time unit. Whether the operating frequency of the terminal device is set according to the first sub - mode or the third sub - mode, the impact on the first uplink signal and the second uplink signal is minimized.

[0320] However, if the network device instructs the terminal device to set the operating frequency according to the second sub - mode, the terminal device needs to set the operating frequency before the first uplink signal is sent completely. And the second uplink signal is temporally after the first uplink signal, that is, the second uplink signal is sent after the first uplink signal is sent completely. If the operating frequency is set before the first uplink signal is sent completely, it may cause the second uplink signal not to be sent. Therefore, in order to enable both the first uplink signal and the second uplink signal to be sent as normally as possible, the network device can instruct the terminal device to set the operating frequency according to the first sub - mode or the third sub - mode.

[0321] In the second case, the second signaling also instructs the terminal device to set the operating frequency. For example, the second signaling instructs the terminal device to set the operating frequency in a second manner, and the second signaling may indicate a third frequency. If the terminal device sets the operating frequency according to the second signaling, then the terminal device needs to set the operating frequency according to the third frequency. Herein, the third frequency and the first frequency may be the same frequency, or may also be different frequencies. In this case, the first signaling instructs the terminal device to set the operating frequency, and the second signaling also instructs the terminal device to set the operating frequency. Among them, the second manner may also include one of the first sub-manner, the second sub-manner, or the third sub-manner as described above. The first manner indicated by the first signaling and the second manner indicated by the second signaling may be the same manner. For example, both are the second sub-manner as described above. Or, the first manner indicated by the first signaling and the second manner indicated by the second signaling may also be different manners. For example, the first manner indicated by the first signaling is the first sub-manner as described above, and the second signaling indicates the third sub-manner as described above.

[0322] In this case, the terminal device may set the operating frequency of the terminal device according to the indication of the second signaling. Since the second uplink signal is temporally after the first uplink signal, the network device may first determine the first signaling and then determine the second signaling. The second signaling may be more accurate than the first signaling. For example, the terminal device may set the operating frequency of the terminal device according to the indication of the second signaling after sending the first uplink signal and the second uplink signal. Of course, if the second signaling indicates to set the operating frequency according to the second sub-manner, then the terminal device sets the operating frequency of the terminal device before sending the second uplink signal. And "before sending the second uplink signal" may also be understood as "after sending the second uplink signal".

[0323] Alternatively, in this case, the terminal device may also give priority to the indication of the first signaling, that is, the terminal device sets the operating frequency of the terminal device according to the indication of the first signaling. For example, after the terminal device sends the first uplink signal, it sets the operating frequency of the terminal device according to the indication of the first signaling. For example, the previous operating frequency of the terminal device is frequency 1. After the terminal device sends the first uplink signal at frequency 1, it sets the operating frequency according to the indication of the first signaling. For example, the set operating frequency (i.e., the first frequency) is frequency 2, then the terminal device will operate at frequency 2. If the terminal device can reset the operating frequency to frequency 1 again before the time domain resource of the second uplink signal arrives, the terminal device can continue to send the second uplink signal completely; or, if a part of the time domain resource of the second uplink signal has become invalid when the terminal device resets the operating frequency to frequency 1, then the terminal device can continue to use the non-invalid time domain resource to send a part of the second uplink signal. In this case, the terminal device will discard a part of the second uplink signal; or, if the time domain resource of the second uplink signal has become completely invalid when the terminal device resets the operating frequency to frequency 1, the terminal device cannot send the second uplink signal anymore. In this case, the terminal device will completely discard the second uplink signal.

[0324] For example, the first uplink signal is PUSCH and the second uplink signal is SRS. For example, the second uplink signal is an aperiodic SRS scheduled by DCI, and both the second DCI and the first DCI instruct the terminal device to set the operating frequency. Since the second uplink signal is scheduled by DCI, it may have a higher priority or a higher urgency level. Therefore, the terminal device may ignore the indication of the first DCI and instead set the operating frequency according to the indication of the second DCI. Or, for example, the first uplink signal is PUSCH and the second uplink signal is a periodic SRS or a semi-static SRS configured by higher layer signaling. Then, the second uplink signal may not have a high urgency level or priority compared to the first uplink signal. Therefore, the terminal device may try to ensure the normal transmission of the first uplink signal and try to ensure the response to the first signaling. For example, after sending PUSCH, the terminal device sets the operating frequency according to the indication of the first signaling.

[0325] In the embodiment of the present application, the network device may instruct the terminal device to set the operating frequency through the first signaling, and the terminal device may set it according to the indication of the network device. That is, the network device can know the operating frequency of the terminal device. Thus, when the network device schedules the terminal device, it can determine whether to instruct the terminal device to switch the operating frequency. Through this method, the network device can clarify the current operating frequency of the terminal device, so that the network device can better schedule the terminal device.

[0326] To solve the same technical problem, a second communication method is provided in an embodiment of this application. Please refer to Figure 8 , which is a flowchart of this method. In the following introduction, this method is applied to Figures 3 - 6 the network architecture shown in any one of the accompanying drawings as an example. In addition, this method can be executed by two communication devices. These two communication devices are, for example, a third communication device and a fourth communication device. Among them, the third communication device can be a network device or a communication device that can support the network device to implement the functions required for this method, or the third communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required for this method. Of course, it can also be other communication devices, such as a chip system. The fourth communication device can be a network device or a communication device that can support the network device to implement the functions required for this method, or the fourth communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required for this method. Of course, it can also be other communication devices, such as a chip system. And there are no restrictions on the implementation manners of the third communication device and the fourth communication device. For example, the third communication device can be a network device, the fourth communication device is a terminal device, or both the third communication device and the fourth communication device are network devices, or both the third communication device and the fourth communication device are terminal devices, or the third communication device is a network device, and the fourth communication device is a chip system that can support the terminal device to implement the functions required for this method, and so on. Among them, the network device is, for example, a base station.

[0327] For the convenience of introduction, in the following, this method is taken as an example of being executed by a network device and a terminal device. That is to say, the third communication device is a terminal device and the fourth communication device is a network device as an example. If the embodiment of this application is applied in Figures 3 - 6 the network architecture shown in any one of the accompanying drawings, then the terminal device described below can be Figures 3 - 6 the terminal device in the network architecture shown in any one of the accompanying drawings. In addition, the network device described below can be Figures 3 - 6 an LTE network device or an NR network device in the network architecture shown in any one of the accompanying drawings.

[0328] S81. The terminal device sends a first uplink signal to the network device on a first uplink carrier, and the network device receives the first uplink signal from the terminal device on the first uplink carrier.

[0329] In the embodiments of the present application, the antenna of the terminal device can operate on at least two uplink carriers. However, at a certain moment, the antenna of the terminal device can only operate on one of the at least two uplink carriers. The at least two uplink carriers include a first uplink carrier. The first uplink carrier is, for example, an ordinary uplink carrier, or it can also be SUL. The at least two uplink carriers can include one NR uplink carrier and one LTE uplink carrier, or the at least two uplink carriers include the uplink carriers of two different cells, and there is no specific limitation.

[0330] S82. The network device determines the operating frequency of the terminal device. For example, the network device can directly determine the operating frequency of the terminal device, or the network device determines that the terminal device sets the operating frequency of the terminal device according to the first condition.

[0331] The first condition includes, for example, one of the first sub-condition, the second sub-condition, the third sub-condition, or the fourth sub-condition, or it may also include other sub-conditions. The first sub-condition, the second sub-condition, the third sub-condition, and the fourth sub-condition will be introduced below.

[0332] 1. The first sub-condition: Before the terminal device sends an uplink signal to the network device on an uplink carrier other than the first uplink carrier, the operating frequency of the terminal device corresponds to the first uplink carrier. For example, the operating frequency of the terminal device is the second frequency.

[0333] Equivalently, after the terminal device sends the first uplink signal to the network device on the first uplink carrier, until the terminal device sends an uplink signal to the network device on another uplink carrier again, the operating frequency of the terminal device remains at the second frequency. For example, at the first moment, the terminal device sends the first uplink signal to the network device on the first uplink carrier. At the second moment after the first moment, the terminal device sends the first uplink signal to the network device on the second uplink carrier. During the period between the first moment and the second moment, the terminal device has not sent an uplink signal to the network device through an uplink carrier other than the first uplink carrier. Then, before the second moment, the operating frequency of the terminal device corresponds to the first uplink carrier. In addition, between the first moment and the second moment, the terminal device may send other uplink signals to the network device through the first uplink carrier in addition to the above uplink signal, or the terminal device may not send other uplink signals to the network device through the first uplink carrier, and there is no limitation on this.

[0334] The terminal device sets the operating frequency of the terminal device according to the first sub-condition, which can also be understood as the terminal device maintains the operating frequency of the terminal device corresponding to the first uplink carrier according to the first sub-condition.

[0335] 2. Second sub-condition: Within the first time period after the terminal device sends the first uplink signal, if the terminal device does not send an uplink signal to the network device within the first time period, within the first time period, the operating frequency of the terminal device corresponds to the first uplink carrier.

[0336] For example, the terminal device can start timing after sending the first uplink signal (e.g., when the first uplink signal is sent successfully). Until the first time period arrives, if the terminal device does not send any uplink signal to the network device, then within the first time period, the operating frequency of the terminal device corresponds to the first uplink carrier. After the first time period, there is no longer any restriction on the frequency of the terminal device. For example, the terminal device can decide whether to switch the frequency of the terminal device according to the situation, and the network device can no longer control it. For example, the terminal device can use a timer to time, or use other methods to time. The first time period can be configured by the network device or specified by a protocol.

[0337] There is also a situation where the terminal device starts timing after sending the first uplink signal successfully. It is very likely that before the first time period arrives, the terminal device sends another uplink signal to the network device, for example, called the second uplink signal. If this situation occurs, then after the terminal device sends the second uplink signal (e.g., when the second uplink signal is sent successfully), it can start timing again for the first time period. Until the first time period arrives, if the terminal device does not send any uplink signal to the network device, then within the first time period, the operating frequency of the terminal device corresponds to the first uplink carrier. And so on.

[0338] The second sub-condition is more suitable for the scenario where the network device has continuous scheduling of the terminal device on the first uplink carrier. For example, if the network device performs continuous scheduling on the terminal device, then the terminal device may maintain within the first time period during the scheduling time of the network device by timing the first time period in the above loop. Then the operating frequency of the terminal device always corresponds to the first uplink carrier. During the scheduling process, the terminal device does not need to perform frequency switching, saving the power consumption of the terminal device and also reducing the scheduling delay.

[0339] The terminal device sets the operating frequency of the terminal device according to the second sub-condition. It can also be understood that the terminal device maintains the operating frequency of the terminal device corresponding to the first uplink carrier according to the second sub-condition.

[0340] It should be noted that the second sub-condition can be understood as follows: within the first time period after the first moment, if the terminal device does not send an uplink signal to the network device, then within the first time period, the operating frequency of the terminal device corresponds to the first uplink carrier. In the second sub-condition, the first moment is the end moment when the terminal device sends the first uplink signal. The embodiments of the present application do not limit this first moment, and this first moment can also be other moments, such as the start moment when the terminal device sends the first uplink signal, or the end moment when the terminal device receives the first signaling for instructing the terminal device to send the first uplink signal, or the end moment when receiving the downlink signal carrying the first signaling for instructing the terminal device to send the first uplink signal, or a certain moment after these end moments.

[0341] 3. Third sub-condition: within the second time period after the terminal device sends the first uplink signal, if the terminal device does not send an uplink signal to the network device, then after the second time period, the operating frequency of the terminal device corresponds to the first frequency.

[0342] Among them, the first frequency can be a pre-determined frequency.

[0343] As an implementation manner of the pre-determined frequency, the pre-determined frequency can be indicated by the first signaling sent by the network device to the terminal device. For example, the network device sends the first signaling to the terminal device, and the terminal device receives the first signaling from the network device. The first signaling indicates the first frequency, then the terminal device can determine the first frequency. The first signaling is, for example, sent by the network device to the terminal device before S81. The first signaling is, for example, DCI, or can also be other types of information, such as high-layer signaling, etc. Among them, the high-layer signaling is, for example, RRC signaling or MAC layer signaling, etc.

[0344] For example, the first frequency can be determined according to the frequency corresponding to the uplink carrier for which PUCCH is configured for the terminal device. For example, the first frequency is the frequency corresponding to the uplink carrier for which PUCCH is configured for the terminal device. Or, the first frequency can also be the frequency corresponding to other uplink carriers supported by the terminal device except for the uplink carrier for which PUCCH is configured.

[0345] As another implementation of the predetermined frequency, the predetermined frequency may be a predefined frequency. For example, the predetermined frequency is predefined by a protocol or preconfigured in the terminal device. For example, the predefined frequency may be the frequency corresponding to the low-frequency carrier among at least two uplink carriers, or may be the frequency corresponding to the high-frequency carrier among at least two uplink carriers. Another example is that when at least two uplink carriers include a SUL carrier and a normal uplink carrier, the predefined frequency may be the frequency corresponding to the SUL carrier, or may also be the frequency corresponding to the normal uplink carrier. Still another example is that when at least two uplink carriers include an LTE uplink carrier and an NR uplink carrier, the predefined frequency may be the frequency corresponding to the NR uplink carrier, or may also be the frequency corresponding to the LTE uplink carrier. Yet another example is that when at least two uplink carriers include the uplink carrier of the primary cell and the uplink carrier of the secondary cell, the predefined frequency may be the frequency corresponding to the uplink carrier of the primary cell.

[0346] There is no specific limitation on how the predetermined frequency is determined.

[0347] The first frequency may be the frequency corresponding to the first uplink carrier, or may also be the frequency corresponding to other uplink carriers supported by the terminal device except the first uplink carrier.

[0348] For example, the terminal device may start timing after sending the first uplink signal (for example, when the first uplink signal is sent successfully). Until the second duration arrives, if the terminal device does not send any uplink signals to the network device, then after the second duration, the operating frequency of the terminal device is the first frequency. During the second duration, there is no limitation on the frequency of the terminal device. For example, the terminal device may decide whether to switch the frequency of the terminal device according to the situation, and the network device may no longer control it. For example, the terminal device may time through a timer or other means. The second duration may be configured by the network device or specified by a protocol.

[0349] There is another situation. After the terminal device finishes sending the first uplink signal and starts timing, it is very likely that before the second duration arrives, the terminal device sends another uplink signal to the network device, for example, called the third uplink signal. If this situation occurs, then after the terminal device sends the third uplink signal (for example, when the third uplink signal is sent successfully), it can start timing again and time for the second duration. Until the second duration arrives, if the terminal device does not send any uplink signals to the network device, then during the second duration, the operating frequency of the terminal device is the first frequency. And so on.

[0350] The third sub-condition is more suitable for the scenario where the network device has not scheduled the terminal device for a long time. For example, after the network device schedules the terminal device to send a first uplink signal on a first uplink carrier and then does not schedule the terminal device for a long time, the terminal device may maintain its operating frequency at the first frequency during the time when the network device does not schedule it by means of the above-mentioned cyclic timing of the second duration. Then, when the network device schedules the terminal device again, it can know that the operating frequency of the terminal device is the first frequency. The network device can then determine whether the terminal device needs to switch its operating frequency according to the scheduling situation. If the terminal device needs to switch its operating frequency, the network device can reserve corresponding time for the terminal device to switch its operating frequency, thereby reducing the probability of the terminal device discarding signals.

[0351] If the first frequency is the frequency corresponding to the first uplink carrier, then the terminal device sets its operating frequency according to the third sub-condition. It can also be understood that the terminal device maintains its operating frequency corresponding to the first uplink carrier according to the third sub-condition. Or, if the first frequency is not the frequency corresponding to the first uplink carrier, then the terminal device sets its operating frequency according to the third sub-condition. It can also be understood that the terminal device switches its operating frequency according to the third sub-condition.

[0352] It should be noted that the third sub-condition can be understood as follows: within the second duration after the second moment, if the terminal device does not send an uplink signal to the network device, then after the second duration, the operating frequency of the terminal device corresponds to the first frequency. In the third sub-condition, the second moment is the end moment when the terminal device sends the first uplink signal. The embodiments of the present application do not limit this second moment, and this second moment can also be other moments, such as the start moment when the terminal device sends the first uplink signal, or the end moment when the terminal device receives the first signaling for instructing the terminal device to send the first uplink signal, or the end moment when receiving the downlink signal carrying the first signaling for instructing the terminal device to send the first uplink signal, or a certain moment after these end moments.

[0353] 4. Fourth sub-condition: within the first duration after the terminal device sends the first uplink signal, if the terminal device does not send an uplink signal to the network device, within the first duration, the operating frequency of the terminal device corresponds to the first uplink carrier, and within the second duration after the terminal device sends the first uplink signal, if the terminal device does not send an uplink signal to the network device, then after the second duration, the operating frequency of the terminal device corresponds to the first frequency.

[0354] The fourth sub-condition is equivalent to combining the second sub-condition and the third sub-condition.

[0355] For example, the terminal device can start timing after sending the first uplink signal (e.g., when the first uplink signal is sent successfully). Until the first duration arrives, if the terminal device has not sent any uplink signals to the network device, then within the first duration, the operating frequency of the terminal device corresponds to the first uplink carrier. After the first duration, there is no longer any restriction on the frequency of the terminal device. For example, the terminal device can decide whether to switch the frequency of the terminal device according to the situation, and the network device can stop controlling. For example, the terminal device can use the first timer to time, or use other methods to time. The first duration can be configured by the network device, or can be specified by the protocol. Additionally, for example, the terminal device can start timing after sending the first uplink signal (e.g., when the first uplink signal is sent successfully). Until the second duration arrives, if the terminal device has not sent any uplink signals to the network device, then after the second duration, the operating frequency of the terminal device is the first frequency. Within the second duration, there is no longer any restriction on the frequency of the terminal device. For example, the terminal device can decide whether to switch the frequency of the terminal device according to the situation, and the network device can stop controlling. For example, the terminal device can use the second timer to time, or use other methods to time. The second duration can be configured by the network device, or can be specified by the protocol.

[0356] For example, the length of the second duration is greater than that of the first duration, refer to Figure 9 . Figure 9 Let t1 represent the time when the first uplink signal is sent successfully, and the terminal reports starting to time from t1. Let t2 represent the end time of the first duration, and t3 represent the end time of the second duration. For example, between the t1 moment and the t2 moment, the terminal device has not sent any uplink signals to the network device, then between the t1 moment and the t2 moment, the operating frequency of the terminal device remains at the frequency corresponding to the first uplink carrier. For example, between the t1 moment and the t3 moment (that is, in addition to between the t1 moment and the t2 moment, it also includes between the t2 moment and the t3 moment), the terminal device has not sent any uplink signals to the network device, then after the t3 moment, the operating frequency of the terminal device remains at the first frequency. Between the t2 moment and the t3 moment, there is no restriction on the frequency of the terminal device.

[0357] For the introduction of the corresponding details of the fourth sub-condition, reference can be made to the introduction of the second sub-condition or the third sub-condition accordingly.

[0358] If the first frequency is the frequency corresponding to the first uplink carrier, then the terminal device sets the operating frequency of the terminal device according to the fourth sub-condition. It can also be understood that the terminal device maintains the operating frequency of the terminal device corresponding to the first uplink carrier according to the third sub-condition. Or, if the first frequency is not the frequency corresponding to the first uplink carrier, then the terminal device sets the operating frequency of the terminal device according to the fourth sub-condition. It can also be understood that the terminal device switches the operating frequency of the terminal device according to the fourth sub-condition.

[0359] S83. The terminal device sets the operating frequency. For example, the terminal device may set the operating frequency according to the first condition.

[0360] Regarding the first condition, reference can be made to the introduction in S82. Among them, S82 may be executed before S83, or S82 may be executed after S83, or S82 and S83 may be executed simultaneously.

[0361] For example, if the terminal device sets the operating frequency of the terminal device according to the first sub-condition as described above, then after the network device receives the first uplink signal from the terminal device on the first uplink carrier, if it is necessary to schedule the terminal device, it can determine that the operating frequency of the terminal device corresponds to the first uplink carrier. Or, for example, if the terminal device sets the operating frequency of the terminal device according to the second sub-condition or the fourth sub-condition as described above, then if the network device needs to schedule the terminal device within the first time period, it can determine that the operating frequency of the terminal device corresponds to the first uplink carrier. Then, if the network device wants to schedule the terminal device to send an uplink signal at a frequency corresponding to the first uplink carrier, that is to say, if the network device continues to schedule the terminal device to send an uplink signal on the first uplink carrier, then the network device does not need to instruct the terminal device to switch the operating frequency, but can directly schedule it, and the terminal device can complete the sending of the uplink signal without switching the operating frequency. For example, the network device sends a second signaling to the terminal device, and the second signaling is used to schedule the terminal device to send a second uplink signal to the network device on the first uplink carrier. Then the second signaling does not need to instruct the terminal device to set the operating frequency of the terminal device, and the terminal device does not need to set the operating frequency either, but can directly send the second uplink signal to the network device, and the network device can receive the second uplink signal from the terminal device on the first uplink carrier. Here, "setting" the operating frequency can be understood as "switching" the operating frequency.

[0362] Alternatively, after receiving the first uplink signal from the terminal device on the first uplink carrier, if the network device wants to schedule the terminal device to send an uplink signal on a frequency that does not correspond to the first uplink carrier, or wants to schedule the terminal device to send an uplink signal on a frequency that does not correspond to the first uplink carrier within the first duration, that is to say, the network device wants to schedule the terminal device to send an uplink signal on other uplink carriers, then when the network device schedules the terminal device, it can instruct the terminal device to set the operating frequency of the terminal device. For example, the network device sends a second signaling to the terminal device, and the second signaling is used to schedule the terminal device to send a second uplink signal to the network device on the second uplink carrier. Then the second signaling can instruct the terminal device to set the operating frequency of the terminal device. In addition, the second signaling can also indicate a second frequency, and the second frequency is the target frequency that the terminal device needs to set. That is to say, the terminal device needs to set the operating frequency of the terminal device according to the second frequency, or rather, the terminal device needs to set the operating frequency of the terminal device to the second frequency. Alternatively, the second signaling may not need to instruct the terminal device to set the operating frequency of the terminal device, but only indicate the second frequency, and the second signaling can also indicate one or more OFDM symbols. Then the terminal device can set the operating frequency of the terminal device to the second frequency within these one or more OFDM symbols. After setting the operating frequency, the terminal device can send a second uplink signal to the network device on the second uplink carrier, and the network device can receive the second uplink signal from the terminal device on the second uplink carrier.

[0363] For example, if the terminal device sets the operating frequency of the terminal device according to the third sub-condition or the fourth sub-condition as described above, then if the network device needs to schedule the terminal device after the second duration, it can determine that the operating frequency of the terminal device is the first frequency. Then, if the network device wants to schedule the terminal device to send an uplink signal on a frequency corresponding to the first uplink carrier, then, if the network device wants to schedule the terminal device to send an uplink signal on the first frequency, the network device does not need to instruct the terminal device to switch the operating frequency, but can directly schedule it. The terminal device can complete the sending of the uplink signal without switching the operating frequency. For example, the network device sends a second signaling to the terminal device, and the second signaling is used to schedule the terminal device to send a second uplink signal to the network device on the first frequency. Then the second signaling does not need to instruct the terminal device to set the operating frequency of the terminal device, and the terminal device does not need to set the operating frequency either, but can directly send the second uplink signal to the network device. The network device can receive the second uplink signal from the terminal device on the first frequency. Here, "setting" the operating frequency can be understood as "switching" the operating frequency.

[0364] Alternatively, if the network device wants to schedule the terminal device to send an uplink signal on a second frequency within a second time period, that is, the network device wants to schedule the terminal device to send an uplink signal on a frequency other than the first frequency, then when the network device schedules the terminal device, it can instruct the terminal device to set the operating frequency of the terminal device. For example, the network device sends a second signaling to the terminal device, and the second signaling is used to schedule the terminal device to send a second uplink signal to the network device on the second frequency. Then the second signaling can instruct the terminal device to set the operating frequency of the terminal device. In addition, the second signaling can also indicate the second frequency, and the second frequency is the target frequency that the terminal device needs to set. That is, the terminal device needs to set the operating frequency of the terminal device according to the second frequency. Or, the terminal device needs to set the operating frequency of the terminal device to the second frequency. Alternatively, the second signaling may not need to instruct the terminal device to set the operating frequency of the terminal device, but only indicate the second frequency, and the second signaling can also indicate one or more OFDM symbols. Then the terminal device can set the operating frequency of the terminal device to the second frequency within these one or more OFDM symbols. After setting the operating frequency, the terminal device can send a second uplink signal to the network device on the second frequency, and the network device can receive the second uplink signal from the terminal device on the second frequency.

[0365] In the embodiments of the present application, the terminal device can set the operating frequency according to the first condition, and the network device can also clarify that the terminal device will set the operating frequency according to the first condition. Thus, the network device can determine the operating frequency of the terminal device. Therefore, when scheduling the terminal device, it can be determined whether to reserve time for the terminal device to set the operating frequency, so as to reduce the probability of the terminal device discarding signals and improve the signal transmission quality.

[0366] To solve the same technical problem, the embodiments of the present application provide a third communication method. Please refer to Figure 10 , which is the flowchart of this method. In the following introduction process, it is assumed that this method is applied to Figures 3 - 6Take the network architecture shown in any of the accompanying drawings as an example. Additionally, this method can be executed by two communication devices, such as a fifth communication device and a sixth communication device. Among them, the fifth communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by this method, or the fifth communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by this method. Of course, it can also be other communication devices, such as a chip system. The sixth communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by this method, or the sixth communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by this method. Of course, it can also be other communication devices, such as a chip system. And there are no restrictions on the implementation methods of the fifth communication device and the sixth communication device. For example, the fifth communication device can be a network device, the sixth communication device is a terminal device, or both the fifth communication device and the sixth communication device are network devices, or both the fifth communication device and the sixth communication device are terminal devices, or the fifth communication device is a network device, and the sixth communication device is a chip system capable of supporting the terminal device to implement the functions required by this method, and so on. Among them, the network device is, for example, a base station.

[0367] For the sake of convenience in introduction, hereinafter, take the example that this method is executed by a network device and a terminal device. That is to say, take the fifth communication device as a terminal device and the sixth communication device as a network device as an example. If the embodiments of this application are applied in Figures 3 - 6 any network architecture shown in any of the accompanying drawings, then the terminal device described hereinafter can be Figures 3 - 6 the terminal device in any network architecture shown in any of the accompanying drawings. Additionally, the network device described hereinafter can be Figures 3 - 6 an LTE network device or an NR network device in any network architecture shown in any of the accompanying drawings.

[0368] S101. The network device sends a first signaling to the terminal device, and the terminal device receives the first signaling from the network device. The first signaling is used to indicate the default operating frequency of the terminal device.

[0369] For example, the default operating frequency can be a pre-determined frequency.

[0370] As an implementation manner of the pre-determined frequency, the pre-determined frequency can be indicated by the first signaling sent by the network device to the terminal device. For example, the network device sends a first signaling to the terminal device, and the terminal device receives the first signaling from the network device. The first signaling indicates the default operating frequency, then the terminal device can determine the default operating frequency. The first signaling is, for example, DCI, or it can also be other types of information, such as high-layer signaling, etc. Among them, the high-layer signaling is, for example, RRC signaling or MAC layer signaling, etc.

[0371] For example, the default operating frequency may be determined according to the frequency corresponding to the second uplink carrier. The second uplink carrier may be, for example, a high-frequency carrier, a low-frequency carrier, or a carrier pre-configured by the network device. For example, the second uplink carrier is the uplink carrier for which PUCCH is configured for the terminal device. The default operating frequency may be determined according to the frequency corresponding to the uplink carrier for which PUCCH is configured for the terminal device. For example, the default operating frequency is the frequency corresponding to the uplink carrier for which PUCCH is configured for the terminal device. Alternatively, the default operating frequency may also be the frequency corresponding to other uplink carriers supported by the terminal device except for the uplink carrier for which PUCCH is configured.

[0372] As another implementation of the pre-determined frequency, the pre-determined frequency may be a pre-defined frequency. For example, the pre-determined frequency is pre-defined by a protocol or pre-configured in the terminal device. For example, the pre-defined frequency may be the frequency corresponding to the low-frequency carrier among at least two uplink carriers, or may be the frequency corresponding to the high-frequency carrier among at least two uplink carriers. Another example is that when at least two uplink carriers include an SUL carrier and a normal uplink carrier, the pre-defined frequency may be the frequency corresponding to the SUL carrier, or may also be the frequency corresponding to the normal uplink carrier. Still another example is that when at least two uplink carriers include an LTE uplink carrier and an NR uplink carrier, the pre-defined frequency may be the frequency corresponding to the NR uplink carrier, or may also be the frequency corresponding to the LTE uplink carrier. Yet another example is that when at least two uplink carriers include the uplink carrier of the primary cell and the uplink carrier of the secondary cell, the pre-defined frequency may be the frequency corresponding to the uplink carrier of the primary cell. In this case, the network device may not need to send the first signaling to the terminal device, so S101 does not need to be executed. Alternatively, although the network device will send the first signaling to the terminal device, the first signaling may not need to indicate the default operating frequency.

[0373] There is no specific limitation on how to determine the pre-determined frequency.

[0374] S102: The terminal device sends an uplink signal to the network device on the first uplink carrier, and the network device receives the uplink signal from the terminal device on the first uplink carrier.

[0375] In the embodiments of the present application, the antenna of the terminal device can operate on at least two uplink carriers. However, at a certain moment, the antenna of the terminal device can only operate on one of the at least two uplink carriers. The at least two uplink carriers include the first uplink carrier. The first uplink carrier may be, for example, a normal uplink carrier, or may also be SUL. The at least two uplink carriers may include an NR uplink carrier and an LTE uplink carrier, or the at least two uplink carriers include the uplink carriers of two different cells. There is no specific limitation.

[0376] Optionally, before the terminal device sends an uplink signal on the first uplink carrier to the network device, the network device may send a first signaling to the terminal device. Then the terminal device receives the first signaling from the network device. The first signaling instructs the terminal device to send an uplink signal to the network device on the first uplink carrier, and the first signaling is carried in a downlink signal. When the first uplink carrier corresponds to the default operating frequency, if the duration between the end time of receiving the downlink signal and the start time of sending the uplink signal by the terminal device is less than a first duration, the terminal device may ignore the indication of the first signaling; when the first uplink carrier does not correspond to the default operating frequency, if the duration between the end time of receiving the downlink signal and the start time of sending the uplink signal by the terminal device is less than a second duration, the terminal device may ignore the indication of the first signaling, and the first duration is less than the second duration.

[0377] It should be understood that when the first uplink carrier corresponds to the default operating frequency, the terminal device does not need to change the operating frequency, while when the first uplink carrier does not correspond to the default operating frequency, the terminal device needs to set the operating frequency from the default operating frequency to the frequency corresponding to the first uplink carrier. Therefore, compared with the case where the first uplink carrier corresponds to the default operating frequency, it requires a longer processing time.

[0378] S103. When the first uplink carrier corresponds to the default operating frequency, the terminal device maintains the operating frequency of the terminal device corresponding to the default operating frequency; or, when the first uplink carrier does not correspond to the default operating frequency, the terminal device sets the operating frequency of the terminal device to the default operating frequency.

[0379] After the terminal device sends an uplink signal to the network device, the terminal device may set the operating frequency of the terminal device to the default operating frequency. That is to say, in the embodiments of the present application, regardless of which frequency the terminal device sends an uplink signal to the network device, after the sending is completed, if the frequency is the default operating frequency, the terminal device continues to maintain the operating frequency of the terminal device as the default operating frequency, and if the frequency is not the default operating frequency, the terminal device may re-switch the operating frequency of the terminal device to the default operating frequency. Equivalently, the terminal device continuously maintains the operating frequency at the default operating frequency, so that when the network device schedules the terminal device, it can be clear that the operating frequency of the terminal device is the default operating frequency.

[0380] For example, when a network device needs to schedule a terminal device, the network device can determine that the operating frequency of the terminal device is the default operating frequency. Then, if the network device wants to schedule the terminal device to send an uplink signal at the default operating frequency, the network device can directly schedule it, and the terminal device can complete the sending of the uplink signal without switching the operating frequency. For example, the network device sends a second signaling to the terminal device, and the second signaling is used to schedule the terminal device to send a second uplink signal to the network device at the default operating frequency. Then, the terminal device does not need to set the operating frequency, but directly sends the second uplink signal to the network device, and the network device can receive the second uplink signal from the terminal device at the default operating frequency. Here, "setting" the operating frequency can be understood as "switching" the operating frequency.

[0381] Alternatively, if the network device wants to schedule the terminal device to send an uplink signal at a first frequency, and the first frequency is not the default operating frequency, that is, the network device wants to schedule the terminal device to send an uplink signal at a frequency other than the default operating frequency, then when the network device schedules the terminal device, it can instruct the terminal device to set the operating frequency of the terminal device. For example, the network device sends a second signaling to the terminal device, and the second signaling is used to schedule the terminal device to send a second uplink signal to the network device at a second frequency. Then, the second signaling can instruct the terminal device to set the operating frequency of the terminal device. In addition, the second signaling can also indicate the first frequency, and the first frequency is the target frequency that the terminal device needs to set. That is to say, the terminal device needs to set the operating frequency of the terminal device according to the first frequency, or rather, the terminal device needs to set the operating frequency of the terminal device to the first frequency. Alternatively, the second signaling may not need to instruct the terminal device to set the operating frequency of the terminal device, but only indicate the first frequency, and the second signaling can also indicate one or more OFDM symbols. Then, the terminal device can set the operating frequency of the terminal device to the first frequency within these one or more OFDM symbols. After setting the operating frequency, the terminal device can send a second uplink signal to the network device at the first frequency, and the network device can receive the second uplink signal from the terminal device at the first frequency.

[0382] In the embodiments of the present application, the default operating frequency can be set. Then, no matter at which frequency the terminal device sends an uplink signal to the network device, after the sending is completed, if the frequency is the default operating frequency, the terminal device continues to maintain the operating frequency of the terminal device as the default operating frequency. If the frequency is not the default operating frequency, the terminal device can switch the operating frequency of the terminal device back to the default operating frequency. Equivalently, the terminal device continuously maintains the operating frequency at the default operating frequency, so that when the network device schedules the terminal device, it can be clear that the operating frequency of the terminal device is the default operating frequency.

[0383] The following describes the apparatus for implementing the above method in the embodiments of the present application with reference to the accompanying drawings. Therefore, the content in the foregoing can be used in the subsequent embodiments, and the repeated content will not be described again.

[0384] Figure 11 It is a schematic block diagram of a communication device 1100 provided in an embodiment of the present application. Exemplarily, the communication device 1100 is, for example, a terminal device 1100. The terminal device 1100 includes a processing module 1110 and a transceiver module 1120. Among them, the processing module 1110 can be used to execute Figure 7 all operations other than the transceiver operations performed by the terminal device in the illustrated embodiment, such as S73, and / or other processes for supporting the technologies described herein. The transceiver module 1120 can be used to execute Figure 7 all transceiver operations performed by the terminal device in the illustrated embodiment, such as S71 and S72, and / or other processes for supporting the technologies described herein. Among them, the transceiver module 1120 can be a functional module, or can also be a general term for two functional modules, which are a sending module and a receiving module respectively. The sending module is used to execute Figure 7 all sending operations performed by the terminal device in the illustrated embodiment, such as S72, and / or other processes for supporting the technologies described herein; the receiving module is used to execute Figure 7 all receiving operations performed by the terminal device in the illustrated embodiment, such as S71, and / or other processes for supporting the technologies described herein.

[0385] For example, the transceiver module 1120 is used to receive a first signaling from a network device, where the first signaling is used to indicate sending a first uplink signal to the network device on a first uplink carrier, and the first signaling further indicates a first frequency;

[0386] The processing module 1110 is used to set the operating frequency according to the first frequency.

[0387] As an optional implementation manner, the processing module 1110 is used to set the operating frequency according to the first frequency in the following manner:

[0388] After the transceiver module 1120 sends the first uplink signal, set the operating frequency according to the first frequency; or,

[0389] Before the end of a first time period corresponding to the first uplink signal sent by the transceiver module 1120, set the operating frequency according to the first frequency, where the first time period is a time domain resource for sending the first uplink signal; or,

[0390] Before the end moment of the time unit where the first uplink signal is located arrives, set the operating frequency according to the first frequency.

[0391] As an alternative implementation, the first frequency corresponds to the first uplink carrier; or, the first frequency corresponds to a second uplink carrier.

[0392] As an alternative implementation, the transceiver module 1120 is further configured to receive a second signaling from the network device, where the second signaling instructs to send a second uplink signal to the network device on the first uplink carrier, and the second uplink signal is within the same time unit as the first uplink signal and the second uplink signal is after the first uplink signal.

[0393] As an alternative implementation,

[0394] The processing module 1110 is configured to set the operating frequency to the first frequency in the following manner after the transceiver module sends the first uplink signal on the first uplink carrier: after the transceiver module 1120 sends the first uplink signal and the second uplink signal, set the operating frequency according to the first frequency; or,

[0395] The processing module 1110 is configured to set the operating frequency to the first frequency in the following manner before the end moment of the time unit where the first uplink signal is located: after the transceiver module 1120 sends the first uplink signal and the second uplink signal, and before the end moment of the time unit where the first uplink signal is located, set the operating frequency according to the first frequency.

[0396] It should be understood that the processing module 1110 in the embodiments of the present application may be implemented by a processor or processor-related circuit components, and the transceiver module 1120 may be implemented by a transceiver or transceiver-related circuit components.

[0397] Such as Figure 12As shown in the figure, an embodiment of the present application further provides a communication device 1200. Exemplarily, the communication device 1200 is, for example, a terminal device 1200. The terminal device 1200 includes a processor 1210, a memory 1220, and a transceiver 1230. Among them, instructions or programs are stored in the memory 1220, and the processor 1210 is configured to execute the instructions or programs stored in the memory 1220. When the instructions or programs stored in the memory 1220 are executed, the processor 1210 is configured to perform the operations performed by the processing module 1110 in the above embodiments, and the transceiver 1230 is configured to perform the operations performed by the transceiver module 1120 in the above embodiments. Among them, the transceiver 1230 may be a functional component, which can both complete the receiving function and the sending function, or the transceiver 1230 may also be a general term for two functional components, which are a transmitter and a receiver. The transmitter is used to complete the function of the terminal device 1200 sending information to other devices, and the receiver is used to complete the function of the terminal device 1200 receiving information from other devices.

[0398] It should be understood that the terminal device 1100 or the terminal device 1200 according to the embodiments of the present application may correspond to Figure 7 the terminal device in the embodiments shown in the figure, and the operations and / or functions of each module in the terminal device 1100 or the terminal device 1200 are respectively for implementing Figure 7 the corresponding processes in the embodiments shown in the figure. For the sake of brevity, they will not be described in detail here.

[0399] Figure 13 It is a schematic block diagram of a communication device 1300 provided by an embodiment of the present application. Exemplarily, the communication device 1300 is, for example, a network device 1300. The network device 1300 includes a processing module 1310 and a transceiver module 1320. Among them, the processing module 1310 may be used to execute Figure 7 all operations other than the transceiver operations performed by the network device in the embodiments shown in the figure, such as the step of generating the first signaling, and / or other processes for supporting the technologies described herein. The transceiver module 1320 may be used to execute Figure 7 all transceiver operations performed by the network device in the embodiments shown in the figure, such as S71 and S72, and / or other processes for supporting the technologies described herein. Among them, the transceiver module 1320 may be a functional module, or may also be a general term for two functional modules, which are a sending module and a receiving module respectively. The sending module is used to execute Figure 7 all sending operations performed by the network device in the embodiments shown in the figure, such as S71, and / or other processes for supporting the technologies described herein; the receiving module is used to execute Figure 7All receiving operations performed by a network device in the illustrated embodiments, such as S72, and / or other processes for supporting the techniques described herein.

[0400] For example, the transceiver module 1320 is configured to send a first signaling to a terminal device, where the first signaling is used to instruct the terminal device to send a first uplink signal to the network device 1300 on a first uplink carrier, and the first signaling further indicates a first frequency.

[0401] As an alternative implementation, the first frequency is used for:

[0402] After sending the first uplink signal on the first uplink carrier, the terminal device sets the operating frequency according to the first frequency; or,

[0403] Before the end of a first time period corresponding to sending the first uplink signal on the first uplink carrier, the terminal device sets the operating frequency according to the first frequency, where the first time period is a time domain resource for sending the first uplink signal; or,

[0404] Before the end moment of the time unit where the first uplink signal is located arrives, the terminal device sets the operating frequency according to the first frequency.

[0405] As an alternative implementation, the first frequency corresponds to the first uplink carrier; or, the first frequency corresponds to a second uplink carrier.

[0406] As an alternative implementation, the transceiver module 1320 is further configured to send a second signaling to the terminal device, where the second signaling instructs the terminal device to send a second uplink signal to the network device 1300 on the first uplink carrier, where the second uplink signal and the first uplink signal are within the same time unit and the second uplink signal is after the first uplink signal.

[0407] It should be understood that the processing module 1310 in the embodiments of the present application may be implemented by a processor or processor-related circuit components, and the transceiver module 1320 may be implemented by a transceiver or transceiver-related circuit components.

[0408] Such as Figure 14As shown, an embodiment of the present application further provides a communication device 1400.
