[0034] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

The terminal device 101 and the network device 102 support multi-service transmission.

[0036] It should be understood that the embodiments of the present application are only illustrative of the communication system 10, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as NR communication system), or future communication systems.

[0045] It should be noted that Figure 1 is merely an example of a system applicable to this application. The methods described in the embodiments of this application are also applicable to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and / or" herein simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the associated objects are in an "or" relationship. It should also be understood that the term "indication" in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain information through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain information through C; or it can mean that A and B have an association relationship. It should also be understood that the term "corresponding" in the embodiments of this application can mean that two objects have a direct or indirect correspondence relationship, an association relationship, or a relationship between an indicator and the indicated, a configuration and the configured, and so on. It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), and the present application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” refers to a standard protocol in the field of communications, for example, it may include LTE protocol, NR protocol, IoT-NTN protocol, NR-NTN protocol and related protocols used in future communication systems, and the present application does not limit this.

[0046] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0047] DRX

[0048] To conserve power in terminals, communication systems all support the DRX transmission mechanism. This mechanism uses a semi-static configuration to achieve discontinuous reception of signals in the time domain. When there is no data transmission, power consumption can be reduced by stopping reception of the Physical Downlink Control Channel (PDCCH) (this also disables PDCCH blind detection).

[0049] The DRX configuration method is to configure a DRX cycle for a UE in the RRC_CONNECTED state. As shown in Figure 2, the DRX cycle consists of "Active Time" and "Inactive Time": During the "Active Time", the UE monitors and receives the PDCCH (Active Period); during the "Inactive Time", the UE does not receive the PDCCH to reduce power consumption (Sleep Period).

[0050] DRX wake-up signal

[0051] In the energy-saving enhancement of NR, DRX ON can also be used in conjunction with the wake-up signal mechanism. Specifically, the terminal receives an indication of the energy-saving wake-up signal before the DRX ON Duration. In conjunction with Figure 2, when the terminal has data transmission in a DRX cycle, the energy-saving wake-up signal "wakes up" the terminal to detect the PDCCH during the DRX ON Duration; otherwise, when the terminal has no data transmission in a DRX cycle, the energy-saving wake-up signal does not "wake up" the terminal, and the terminal does not need to detect the PDCCH during the DRX ON Duration. Compared with the existing DRX mechanism, when the terminal has no data transmission, the terminal can omit the PDCCH detection during the DRX ON Duration, thereby achieving energy saving. The time of the terminal before the DRX ON Duration is called the inactive time. The time of the terminal during the DRX ON Duration is called the active time. The DRX wake-up signal itself also adopts a waveform and structure similar to that of PDCCH.

[0052] ●Terminal complexity optimization

[0053] NR terminals are designed to support extremely high peak rates. Therefore, they require high terminal capabilities. The LTE standard defines a maximum single-carrier bandwidth of 20MHz, with larger bandwidths achieved through multi-carrier aggregation. 5G NR ultimately defines a maximum carrier bandwidth of 100MHz for frequency bands below 6GHz, which is already five times that of LTE. The maximum carrier bandwidth for millimeter-wave frequency bands is 400MHz. The scale of the multiple-input, multiple-output (MIMO) antennas required by NR has also been further increased. The reference antenna configuration for LTE terminals is one transmit, two receive antennas, while frequencies above 2500MHz require dual transmit, four receive antennas. NR R15 / R16 also do not support half-duplex, requiring data processing in all uplink and downlink time slots.

[0054] However, some NR application scenarios, such as the Internet of Things (IoT), industrial automation, and wearable devices, do not require such high processing capacity and speed. These scenarios require communication hardware with low size and power consumption. Lightweight capabilities are a hallmark of these terminals. With this in mind, NR Release 17 is researching and introducing a standard for compact terminals with reduced capabilities.

[0055] The Compact Terminal standard reduces some of the required NR capabilities and defines corresponding terminal function groups for these capabilities. It also further optimizes terminal identification, access procedures, and power consumption measurements to suit relevant application scenarios.

[0056] Such a compact terminal design can significantly reduce the complexity of the terminal hardware and also reduce the energy consumption of the terminal accordingly, thus achieving energy saving.

[0057] As you can understand, the wake-up signal primarily saves energy by controlling the terminal's DRX ON state. This is a method of energy conservation that time-controlled sleep and wake-up. However, the awakened terminal transceiver is often awakened as a whole; it cannot be partially turned on and off based on data throughput.

[0058] The introduction of compact terminals often involves customizing the terminal's transceiver according to fixed capacity specifications. This does not allow for modular transceiver design or the ability to switch parts of the transceiver on and off based on data capacity.

[0059] Based on the above analysis, an embodiment of the present application provides a wireless communication method. FIG3 is a schematic diagram of a first implementation flow of the wireless communication method provided in an embodiment of the present application. As shown in FIG3 , the method includes steps 301 and 302:

[0060] Step 301: A terminal device receives first information sent by a network device, where the first information is used to indicate a switching capability of the terminal device.

[0061] Step 302: The terminal device switches from the first capability to the second capability according to the first information; wherein the terminal device supports multiple capabilities, and the multiple capabilities include the first capability and the second capability.

[0062] It is understood that in the embodiment of the present application, the terminal device supports multiple capabilities. The terminal device switches capabilities based on the instructions of the network device to achieve the purpose of energy saving.

[0063] The following describes further optional implementations and related terms of each of the above steps.

[0064] In step 301, a terminal device receives first information sent by a network device, where the first information is used to indicate a switching capability of the terminal device.

[0065] In the embodiment of the present application, there is no limitation on the signaling in which the first information is carried. The first information can be carried in the downlink signaling during the random access process, and of course, it can also be carried in the downlink signaling after the random access. For example, in some embodiments, the first information is carried in the medium access control (MAC) signaling, downlink control information (DCI) or radio resource control (RRC) signaling.

[0066] In some embodiments, in a DRX mechanism, the first information may also be carried in downlink signaling during the Active Time of the DRX cycle. In other embodiments, in a DRX wake-up signal mechanism, the first information may also be carried in downlink signaling during the DRX ON duration, and / or in signaling carrying a wake-up signal.

[0067] For the embodiment in which the first information is carried in the DCI, in the embodiment of the present application, there is no limitation on the setting method of the first information in the DCI, and it can be various. The first information can indicate the switching capability of the terminal device through the indication field of the existing DCI, or can indicate the switching capability of the terminal device through a new DCI. The first information can indicate the switching capability of the terminal device through a reserved bit / reserved bit in the existing DCI, for example, through a reserved bit of a resource parameter in the DCI to indicate the switching capability of the terminal device, and the resource parameter can be a parameter indicating the number of RBs.

[0068] In the embodiments of the present application, the manner in which the first information indicates is not limited. The first information includes a first numerical value and / or a second numerical value, wherein the first numerical value is used to indicate the switching capability, and the second numerical value is used to indicate the second capability. For example, one capability corresponds to one capability option, and the second numerical value is used to indicate the capability option. It is understood that in the embodiment where the first information includes the second numerical value (excluding the first numerical value), this is also a manner in which the first information indicates the switching capability of the terminal device.

[0069] In step 302, the terminal device switches from a first capability to a second capability according to the first information; wherein the terminal device supports multiple capabilities, and the multiple capabilities include the first capability and the second capability.

[0070] In some embodiments, the first capability is a current capability of the terminal device.

[0071] In some embodiments, step 302 includes: the terminal device switching from the first capability to the second capability according to the second capability indicated by the first information.

[0072] In other embodiments, step 302 includes: the terminal device determining a second capability based on the first information; and the terminal device switching from the first capability to the second capability. For example, in embodiments where the first information does not include the second value, the terminal device may determine the second capability as a default capability based on the first information. For example, the terminal device supports two capabilities, and the default capability is a different capability from the first capability.

[0073] As mentioned above, the terminal device supports multiple capabilities, and a capability is defined by one or more dimensional capabilities. In the embodiments of the present application, there is no limitation on the definition of the capabilities of the terminal device. In some embodiments, the capabilities include one or more of the following (1) to (4):

[0074] (1) the time domain capability of the terminal device;

[0075] (2) the frequency domain capability of the terminal device;

[0076] (3) the spatial dimension capabilities of the terminal device;

[0077] (4) The throughput dimension capability of the terminal device.

[0078] The time domain capability described in (1) above can also be understood as time dimension capability. In some embodiments, the time domain capability of the terminal device includes: the time interval of the unit time channel that the terminal device can receive and / or send; wherein the unit time channel refers to the control channel and / or data channel per unit time.

[0079] It can be understood that defining the capabilities of terminal devices from the perspective of the time domain supports a wider range of capabilities and is more flexible, and can define more different capabilities.

[0080] For example, as shown in FIG4 , the terminal device supports time domain full capability / time domain full capability processing, that is, the time spent receiving a slot's PDCCH / PDSCH is one slot, that is, the terminal device's capability for PDCCH / PDSCH includes once per slot.

[0081] As shown in FIG5 , the terminal device also supports time domain half capability / time domain half capability processing, that is, the time taken to receive a slot of PDCCH / PDSCH is 2 slots, that is, the terminal device's capability for PDCCH / PDSCH includes once every 2 slots.

[0082] As shown in FIG6 , the terminal device also supports sparser time domain capability / sparser time domain processing capability, that is, the time taken to receive a slot of PDCCH / PDSCH is 4 slots, that is, the terminal device's capability for PDCCH / PDSCH includes once every 4 slots.

[0083] Of course, Figures 4 to 6 are only illustrative of the time domain dimension capabilities supported by the terminal device, but this does not constitute a limitation on the embodiments of the present application. The time domain dimension capabilities supported by the terminal device may include: once per slot, once every 2 slots, once every 4 slots and / or once every 8 slots, etc.

[0084] Regarding the frequency domain dimension capability described in (2) above, in some embodiments, it includes: the bandwidth of the control channel and / or data channel that the terminal device can receive and / or send per unit time.

[0085] Optionally, one combination scheme is that the frequency domain dimension capability of the terminal device includes: the bandwidth of the control channel and data channel that the terminal device can receive and send per unit time. The terminal device can support multiple levels of frequency domain dimension capability. Taking resource blocks (RBs) as an example, the bandwidth can be the bandwidth corresponding to {12, 25, 50, 100} RBs.

[0086] The spatial dimension capability described in (3) above can also be understood as spatial dimension capability. In some embodiments, the spatial dimension capability of the terminal device includes: the number of antennas that the terminal device can use; and / or the number of channel layers that the terminal device can receive and / or transmit.

[0087] The throughput dimension capability described in (4) above can also be understood as the throughput capability of information processing. In some embodiments, the throughput dimension capability of the terminal device includes one or more of the following (4-1)-(4-4):

[0088] (4-1) the amount of control information of the control channel that the terminal device can receive and / or send per unit time;

[0089] (4-2) the throughput of the data channels that the terminal device can receive and / or send;

[0090] (4-3) the amount of measurements that the terminal device can perform and / or report per unit time;

[0091] (4-4) The computing throughput that the terminal device can perform.

[0092] Among them, (4-1) is an example of control throughput dimension capability, (4-2) is an example of data throughput dimension capability, and (4-3) is an example of measurement throughput dimension capability.

[0093] For the capability described in (4-1), one combination is the amount of control information of a control channel that a terminal device can receive or send per unit time. In one possible implementation, the amount of control information can be the amount of control information that a terminal device can receive per unit time. For example, the control information is a downlink control information format (DCI Format).

[0094] For the capabilities described in (4-2), one combination is the throughput of the downlink data channel that the terminal device can receive per unit time, for example, the number of bits of downlink data that the terminal device can receive per unit time. Another combination is the throughput of the uplink data channel that the terminal device can send per unit time, for example, the number of bits of uplink data that the terminal device can receive per unit time.

[0095] Regarding the capabilities described in (4-3) above, the amount of measurements that the terminal device can perform per unit time may, for example, refer to the number of downlink measurements or bandwidth that the terminal device can perform per unit time (for example, how many RBs a measurement signal occupies).

[0096] The amount of measurement that a terminal device can report per unit time may, for example, refer to the number of times the terminal device reports a measurement report per unit time, or refer to the cumulative measurement bandwidth reported by the terminal device per unit time (for example, a bandwidth of 20 MHz, if the terminal device measures 10 times per unit time, the cumulative measurement bandwidth reported is 200 MHz).

[0097] The capability described in (4-4) above is, for example, the number of floating-point operations (FLOPs) that the terminal device can perform per unit time.

[0098] As mentioned above, in the embodiment of the present application, the capabilities of the terminal device can be defined from at least one of the time domain dimension capability, frequency domain dimension capability, spatial dimension capability, and throughput dimension capability. As for the capabilities of these four dimensions, the above text has given what specific capabilities these four dimensions can include. It can be seen that in the embodiment of the present application, the capabilities of the terminal device can have multiple combination schemes / combination capabilities, and the definition of the capabilities of the terminal device can be any of the above multiple combination schemes, and any combination scheme falls within the scope of protection of this application;

[0099] in,

[0100] In one possible combination scheme, the capabilities of the terminal device include: the time intervals of the control channels and data channels per unit time that the terminal device can receive and send. It can be understood that in this combination scheme, the capabilities of the terminal device are defined from the dimension of the time domain, which supports a wider range and is more flexible, and can define more different capabilities (for example, the capabilities / processing capabilities of the terminal device for PDCCH / PDSCH include once per slot, once every 2 slots, once every 4 slots and / or once every 8 slots, etc.), which is more beneficial to energy saving of the terminal device.

[0101] In another possible combination scheme, the capabilities of the terminal device include: the bandwidth of the control channel and / or data channel that the terminal device can receive and send per unit time. It can be understood that in this combination scheme, the capabilities of the terminal device are defined from the dimension of the frequency domain, which supports a wider range and is more flexible, and can define more different capabilities (for example, the bandwidth of the control channel and data channel that the terminal device can receive and send per unit time includes {12, 25, 50, 100} RBs), which is more beneficial to energy saving of the terminal device.

[0102] In another possible combination scheme, the capabilities of the terminal device include: the time interval of the control channel and data channel that the terminal device can receive and send per unit time, and the bandwidth of the control channel and / or data channel that the terminal device can receive and send per unit time; in this way, based on the time domain dimension capabilities and the frequency domain dimension capabilities, more different capabilities can be combined, which is beneficial to better optimize the energy saving of the terminal device.

[0103] Optionally, the first information may be received by the terminal device without requesting the network device to switch the capability, or may be received by the terminal device after requesting the network device to switch the capability. In one possible implementation, the wireless communication method shown in FIG7 includes the following steps 701 to 703:

[0104] Step 701: The terminal device sends a first request to the network device, where the first request is used to request a switching capability.

[0105] It can be understood that the network device can send the first information to the terminal device based on the first request.

[0106] In an embodiment of the present application, the first request may or may not include second information, where the second information indicates the processing capability that the terminal device expects to switch to. For example, the second information indicates a second capability. The indication may be a numerical value indicating a capability option, where one capability corresponds to one capability option.

[0107] Step 702: The terminal device receives first information sent by the network device, where the first information is used to indicate the switching capability of the terminal device.

[0108] For the description of the content related to step 702, you can refer to the previous description of step 301 for understanding, and will not be repeated here.

[0109] Step 703: The terminal device switches from the first capability to the second capability according to the first information; wherein the terminal device supports multiple capabilities, and the multiple capabilities include the first capability and the second capability.

[0110] For the description of the content related to step 703, you can refer to the previous description of step 302 for understanding, and will not be repeated here.

[0111] For any of the above embodiments, further, in some embodiments, the terminal device switches from the first capability to the second capability, including: the terminal device switches from the first capability to the second capability within a first time period.

[0112] It is understandable that it takes a certain amount of time for a terminal device to complete the capability switch because the terminal device needs to complete the configuration parameters required to achieve the capability switch. However, to ensure the communication latency of the terminal device and facilitate subsequent scheduling of network devices, in one possible implementation, the terminal device can be restricted to a certain time period to complete the configuration parameter configuration, that is, the terminal device switches from the first capability to the second capability within a first time period.

[0113] In an embodiment of the present application, the first duration may be a default value, may be determined by the terminal device based on the first capability, or may be issued by a network device.

[0114] Regarding the scheme where the network device issues the first duration, in some embodiments, the method further includes: the terminal device receiving fourth information sent by the network device; the fourth information being used to indicate the first duration; wherein the first duration is determined based on the first capability, that is, the first duration is determined based on the capability of the terminal device before capability switching; this is beneficial to subsequent scheduling by the network device. In one possible implementation, the first duration can be K time slots, where K is greater than or equal to 1.

[0115] In some embodiments, the fourth information and the first information may be carried in the same signaling. Of course, the two may also be carried in different signalings, which is not limited in this application.

[0116] It is understandable that after the terminal device completes the capability switching, the corresponding measurement also needs to be adaptively adjusted. That is, in some embodiments, the method further includes: the terminal device performing measurement based on the measurement parameter corresponding to the second capability.

[0117] In a possible implementation, the measurement parameters corresponding to the second capability include: bandwidth, number of RBs, time interval, etc.

[0118] In some embodiments, the terminal device performs measurement based on the measurement parameters corresponding to the second capability, including: the terminal device performs measurement based on the measurement parameters corresponding to the second capability after switching to the second capability for a second duration.

[0119] It is understandable that the switching capability of the terminal device may be advanced, for example, the first information is indicated by a reserved bit in the DCI, so the terminal device needs to make subsequent adjustments after a certain time (for example, L slots, L is greater than or equal to 1) after the switching capability.

[0120] In some embodiments, the terminal device may report multiple capabilities supported by the terminal device to the network device. That is, in some embodiments, any of the above wireless communication methods further includes: the terminal device reporting third information to the network device; the third information is used to indicate the multiple capabilities supported by the terminal device.

[0121] In one possible implementation, the third information is used to indicate the capability options corresponding to the multiple capabilities supported by the terminal device. One capability option corresponds to one capability. For example, the capability corresponding to the first capability option is: two antennas, 25 RBs, and once every 4 slots (i.e., the time interval for receiving PDCCH / PDSCH of 1 time unit is 4 slots). The capability corresponding to another capability option is other combinations different from the first capability option. In short, the multiple capabilities supported by the terminal have a capability definition that includes at least one dimension of capability mentioned above.

[0122] In the embodiment of the present application, there is no restriction on the timing of the terminal device reporting the third information. In some embodiments, the terminal device reporting the third information to the network device includes: the terminal device reporting the third information to the network device after initial access.

[0123] This application does not impose any restrictions on when the terminal device reports the third information to the network device after the initial access is completed. The terminal device can report the third information to the network device at any time after the initial access is completed.

[0124] An embodiment of the present application provides a wireless communication method. FIG8 is a third schematic diagram of an implementation flow of the wireless communication method provided in the embodiment of the present application. As shown in FIG8 , the method includes the following step 801:

[0125] Step 801: A network device sends first information to a terminal device, where the first information is used to indicate a switching capability of the terminal device.

[0126] In the embodiment of the present application, there is no limitation on the manner in which the first information is carried. In some embodiments, the first information is carried in MAC signaling, DCI or RRC signaling.

[0127] It can be understood that the first information is carried in the DCI or MAC signaling, which is beneficial for the terminal device to switch capabilities as early as possible.

[0128] It is understood that, as described above with respect to the embodiments on the terminal device side, the network device can proactively send the first information indicating the switching capability to the terminal device without requiring a request from the terminal device; the network device can also send the first information to the terminal device based on a request from the terminal device. That is, in some embodiments, the method further includes: the network device receiving a first request sent by the terminal device, the first request being used to request the switching capability. For example, in some embodiments, the network device receives the first request sent by the terminal device before sending the first information to the terminal device.

[0129] In some embodiments, the first request carries second information, and the second information is used to indicate the capability that the terminal device expects to switch.

[0130] As described above in the embodiment of the terminal device side, the terminal device can report multiple capabilities supported by the terminal device to the network device. Accordingly, on the network device side, the method further includes: the network device receiving third information reported by the terminal device; the third information is used to indicate the multiple capabilities supported by the terminal device.

[0131] In some embodiments, the network device receives the third information reported by the terminal device, including: the network device receives the third information reported by the terminal device after the terminal device initially accesses.

[0132] In some embodiments, the network device sends the first information to the terminal device, including: the network device sends the first information to the terminal device based on the third information.

[0133] Optionally, in some embodiments, the network device may determine the second capability based on the third information and the service demand of the terminal device (such as unprocessed data in the buffer of the terminal device); the network device sends the first information to the terminal device according to the second capability, and the first information is used to instruct the terminal device to switch from the first capability to the second capability.

[0134] In some embodiments, the wireless communication method on the network device side further includes: the network device sends fourth information to the terminal device, and the fourth information is used to instruct the terminal device to complete the capability switching within the first time period.

[0135] In some embodiments, the first duration is determined based on the capability of the terminal device before capability switching.

[0136] It should be noted that the technical details not described in the wireless communication method on the above-mentioned network device side can be understood by referring to the description of the above-mentioned terminal device side embodiment.

[0137] It can be understood that in the above embodiments, the terminal devices all perform capability switching based on the instructions of the network device, that is, the terminal devices switch from the first capability to the second capability based on the first information sent by the network device. Of course, the terminal device may also perform capability switching not based on the instructions of the network device, and the terminal device may actively switch capabilities without the need for instructions from the network device. That is, an embodiment of the present application provides another wireless communication method, the method comprising: a terminal device switches from a first capability to a second capability; wherein the terminal device supports multiple capabilities, and the multiple capabilities include the first capability and the second capability.

[0138] Furthermore, in some embodiments, the first capability is the current capability of the terminal device.

[0139] Regarding the embodiment of the terminal device actively switching capability, further, in some embodiments, it also includes: the terminal device sends fifth information to the network device, and the fifth information is used to indicate that the terminal device has switched to the second capability.

[0140] For the embodiment of the terminal device's active switching capability, the definition of the capability is the same as described above, that is, the capability includes one or more of the following:

[0141] The time domain capability of the terminal device;

[0142] Frequency domain capability of the terminal device;

[0143] The spatial dimension capability of the terminal device;

[0144] The throughput dimension capability of the terminal device.

[0145] For further embodiments of the above-mentioned dimensional capabilities, please refer to the above description and will not be repeated here.

[0146] The following describes an exemplary application of the embodiments of the present application in a practical application scenario.

[0147] The terminal switches to different capabilities / processing cores based on the base station's switching signal or autonomously. Capabilities are defined in multiple dimensions.

[0148] The terminal's capabilities include time, frequency, and space dimensions, and may also include control throughput, data throughput, and measurement throughput.

[0149] In possible implementation methods, as in method one, the base station instructs the terminal to switch between large and small cores, that is, the base station sends a processing core switching signal (that is, the first information mentioned above) to the terminal, instructing the terminal to dynamically switch to a different processing core; in method two, the terminal autonomously reports the selection of large and small cores, that is, the terminal sends a processing core switching request or an expected processing core to the base station. Based on the terminal's request, the base station sends a processing core switching signal to the terminal, instructing the terminal to dynamically switch to a different processing core.

[0150] Regardless of method 1 or method 2, the following descriptions 1) to 10) are applicable to both methods.

[0151] 1) Different terminal capabilities are defined based on different processing cores. Capabilities are defined based on one or more dimensions: time, frequency, and space. They may also include control throughput, data throughput, and measurement throughput.

[0152] The terminal switches to the processing core corresponding to the instruction in the received switching signal, and controls the transmission and reception, transmission and reception of data, and execution of measurements based on the corresponding capabilities of the processing core.

[0153] 2) Based on 1), the time dimension capabilities defined include:

[0154] The time interval of the control / data channel that the terminal can send and receive, taking PDCCH / PDSCH in time slot units as an example, the terminal device's ability in the time dimension can be once per slot (see Figure 4), once every 2 slots (see Figure 5), once every 4 slots (see Figure 6), once every 8 slots, and so on.

[0155] 3) Based on 1), the frequency domain capabilities defined include:

[0156] The bandwidth of the control / data channel that the terminal can send and receive, taking RB units as an example, the bandwidth can be the number of RBs with different values ​​such as {12, 25, 50, 100} RBs.

[0157] 4) Based on 1), the defined airspace dimension capabilities include:

[0158] The number of antennas or channel layers.

[0159] 5) Based on 1), other dimensional capabilities defined include:

[0160] The amount of control information that the terminal can send or receive on the downlink or uplink control channel;

[0161] Alternatively, the throughput of the downlink or uplink data channel that the terminal can send and receive;

[0162] Alternatively, the amount of measurements that the terminal can perform and report;

[0163] Alternatively, the computing throughput of the terminal, such as the number of floating-point operations (FLOPs) per unit time, etc.

[0164] 6) Based on 1) to 4), the terminal converts the terminal's capabilities according to the conversion signal from the base station.

[0165] The terminal supports multiple different capabilities, each defined based on at least one of the dimensions 2) to 4). A smaller capability corresponds to the lowest capability in the at least one dimension, and a larger capability corresponds to the highest capability in the at least one dimension.

[0166] As shown in Figure 9, the different capabilities of the terminal correspond to at least one large processing core and one small processing core, wherein the capabilities of the small processing core are included in the capabilities of the large processing core.

[0167] A processing core can also be understood as a processing core. It's understood that a terminal supports multiple capabilities. Different capabilities mean different energy consumption, and switching capabilities means changes in power consumption. It's understood that supporting multiple capabilities means supporting multiple hardware combinations that implement different capabilities, with different hardware combinations supporting different capabilities. For example, a hardware set supporting minimum capabilities can be abstractly understood as a small core / small processing core, where a small core has the lowest power consumption. A combination of two small cores creates a large core / large processing core. Compared to a single small core, the terminal has greater capabilities but also consumes more power. By switching between different capabilities, the terminal optimizes power efficiency, enabling it to transmit, receive, and process signals in a more energy-efficient manner. For example, when demand for terminal services is high, the terminal uses a large core; when demand is low, the terminal uses a small core, thereby saving power.

[0168] 7) Based on 6), the terminal can switch to the corresponding capability or processing core through direct instructions of dedicated signaling.

[0169] Alternatively, the terminal can switch the corresponding capabilities indirectly. The terminal can switch specific capabilities through the indication field of the common scheduling DCI or other public DCI control channels. For example, the reserved value of the scheduling resource parameter indicates the switching processing core.

[0170] 8) Based on the different capabilities in 6) to 7), different configuration parameters are corresponding. After receiving the conversion signal, the terminal completes the configuration parameter adjustment within K time slots. The value of K is determined based on the bandwidth, number of RBs, time interval, and other parameters of the capability before the conversion.

[0171] 9) Based on the different capabilities of the terminals in 6) to 8), different measurement parameters are corresponding, such as bandwidth, number of RBs, and time interval, etc. The conversion triggers the corresponding measurement adaptive adjustment.

[0172] 10) Based on 1) to 4), the terminal reports the different capabilities and different processing cores it supports after initial access.

[0173] As can be understood, the above solution allows terminals to adaptively turn on and off parts of their transceivers based on performance requirements such as data throughput. By defining a universally supported minimum processing core, terminals of varying capabilities can be universally connected to the network. When a terminal requires higher data throughput, it switches to a larger processing core. Such terminals no longer need to customize their transceivers according to fixed capability specifications. Terminal transceivers can be designed in a modular manner. Ultimately, terminals can modularly turn on and off parts of their transceivers based on data capacity, achieving dynamic energy savings.

[0174] In the embodiments of the present application, the terminal switches to different capabilities based on a base station's switching signal or autonomously. Capabilities are defined across multiple dimensions, including time, frequency, and space. They may also include control throughput, data throughput, and measurement throughput.

[0175] By switching between different processing cores, the terminal achieves different energy consumption and performance. However, in related technologies, terminals do not have multiple capabilities and can only report fixed capabilities. After connecting to the network, the capabilities remain unchanged. In the embodiments of the present application, however, the terminal has multiple capabilities, thereby achieving power savings through capability switching. Furthermore, in the embodiments of the present application, by indicating the terminal's capability switching in DCI or MAC signaling, the terminal can efficiently and quickly switch between different capabilities.
