Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0036] The network device in this application embodiment can be a device used to communicate with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network.

[0040] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0041] Radio resource control (RRC) status and mobility management

[0042] Currently, the protocol defines three RRC states for terminal devices: RRC connected, RRC idle, and RRC inactive.

[0043] The RRC connected state refers to the state a terminal device is in after completing a random access procedure but before releasing the RRC. An RRC connection exists between the terminal device and a network device (e.g., an access network device). In the RRC connected state, the terminal device can transmit data with the network device, such as downlink and / or uplink data transmission. Alternatively, the terminal device can also transmit terminal-specific data and / or control channels with the network device to transmit specific information or unicast information.

[0044] In RRC connected mode, network devices can determine the cell-level location information of terminal devices, meaning they can identify the cell to which the terminal device belongs. When a terminal device moves in RRC connected mode, such as from one cell to another, the network device can control the terminal device to perform a cell handover. Therefore, mobility management for terminal devices in RRC connected mode can include cell handover. Furthermore, mobility management for terminal devices in RRC connected mode can be controlled by the network device, allowing the terminal device to handover to a designated cell according to instructions issued by the network device.

[0045] RRC idle state refers to the state of a terminal device when it is camped in a cell but has not yet performed random access. The terminal device typically enters the RRC idle state after powering on or after RRC release. In the RRC idle state, there is no RRC connection between the terminal device and network devices (e.g., the camped network device), the network device does not store the terminal device's context, and no connection has been established between the network device and the core network for that terminal device. If the terminal device needs to transition from the RRC idle state to the RRC connected state, it must initiate an RRC connection establishment process.

[0046] In RRC idle state, the core network (CN) can send paging messages to the terminal device; that is, the paging process can be triggered by the CN. Optionally, the paging area can also be configured by the CN. In some cases, for a terminal device in RRC idle state, when the terminal device moves its location (e.g., from one cell to another), the terminal device can initiate a cell reselection process. In other cases, for a terminal device in RRC idle state, when the terminal device needs to access a cell, the terminal device can initiate a cell selection process. In other words, mobility management of a terminal device in RRC idle state can include cell reselection and / or cell selection.

[0047] The RRC inactive state is a state defined to reduce air interface signaling, quickly restore radio connectivity, and quickly restore data services. The RRC inactive state is a state between the connected state and the idle state. The terminal device had previously entered the RRC connected state and then released the RRC connection with the network device, but the network device retained the terminal device's context. Furthermore, the connection established between the network device and the core network for this terminal device was not released; that is, the user plane bearer and control plane bearer between the RAN and CN are still maintained, i.e., a CN-NR connection exists.

[0048] In the RRC inactive state, the RAN can send paging messages to the terminal device, meaning the paging process can be triggered by the RAN. RAN-based paging areas are managed by the RAN, and network devices can determine the location of the terminal device at the RAN paging area level.

[0049] In some cases, for a terminal device in RRC inactive state, when the terminal device moves its location (e.g., from one cell to another), the terminal device can initiate a cell reselection procedure. In other cases, for a terminal device in RRC inactive state, when the terminal device needs to access a cell, the terminal device can initiate a cell selection procedure. In other words, mobility management of a terminal device in RRC inactive state can include cell reselection and / or cell selection.

[0050] 3GPP energy-saving technology

[0051] Currently, the energy-saving technologies provided by 3GPP are mainly divided into terminal equipment power saving (UE power saving) and network equipment energy saving (NW energy saving), which will be introduced separately below.

[0052] In some protocols (e.g., R16), a wake-up signal (WUS) has been introduced for connected terminal devices. The WUS indicates whether the terminal device has entered the discontinuous reception (DRX) on-duration period, helping to reduce unnecessary PDCCH blind checks. In other words, for connected terminal devices, receiving the WUS can determine whether to start the DRX-onduration timer, thereby reducing unnecessary PDCCH blind checks.

[0053] In some protocols (e.g., R17), a paging early indication (PEI) is introduced for terminal devices in idle or inactive states to indicate whether the terminal device needs to listen for paging messages, helping to reduce unnecessary paging message listening. For terminal devices in connected states, a PDCCH skipping mechanism and an SSSG handover mechanism are introduced to reduce unnecessary paging message listening.

[0054] In some protocols (e.g., R18 or R19), a low-power-wake-up signal (LP-WUS) has been introduced. Referring to Figure 2, the terminal device is equipped with a low-power receiver (LR) and a main radio (MR). The terminal device can wake up the MR by receiving the LP-WUS signal based on the LR, thereby achieving energy saving. For terminal devices in idle or inactive states, paging message monitoring based on MR can be triggered by LP-WUS. For terminal devices in connected states, PDCCH blind detection based on MR can be triggered by LP-WUS.

[0055] In some protocols (e.g., R18), the following three mechanisms are introduced for the time domain, frequency domain, spatial domain, and power domain to save power consumption of network devices.

[0056] Mechanism 1: CSI enhancements are introduced for the spatial and energy domains.

[0057] Mechanism 2: A cell DTX / DRX mechanism is introduced for the time domain.

[0058] Mechanism 3: An SSB-less SCell mechanism is introduced for carrier aggregation (CA) scenarios.

[0059] In some protocols (e.g., R19), NES has been further enhanced. An on-demand SSB SCell mechanism has been introduced for terminal devices in the connected state, where the on-demand SSB is configured by the terminal device in the idle or inactive state receiving on-demand SIB1 in a CA scenario.

[0060] In some discussions (e.g., 6G), a terminal device architecture has been proposed to meet the transmission requirements of future communication systems while reducing the power consumption of terminal devices. In this architecture, the terminal device can deploy two types of modems, one of which has superior performance compared to the other. Therefore, the superior modem is called a large modem, and the inferior modem is called a small modem. Accordingly, this architecture can be called a big-little modem architecture.

[0061] Referring to Figure 3, if the terminal device operates based on a little modem (LM), under near-zero load conditions (e.g., when the terminal device is idle or listening), the RF, DBB, and higher layer power consumption of the terminal device are low. However, if the terminal device quickly switches to operating based on a big modem (BM), under full load conditions (e.g., when the terminal device is connected or during peak traffic periods), the RF, DBB, and higher layer power consumption of the terminal device are higher.

[0062] As explained above, a terminal device running only LM can be in an energy-saving state, also known as a low-activity state. A terminal device running BM, on the other hand, can be in a relatively high-energy-consuming state. Typically, if a terminal device needs to transmit large amounts of service data, it can run BM to meet these transmission requirements.

[0063] In other discussions (e.g., 6G), to meet the transmission requirements of future communication systems while reducing the power consumption of terminal devices, a protocol stack architecture, namely the anchor + fast protocol stack, has been proposed. For traditional protocol stacks, one stack is used to transmit all types of data. For the anchor + fast protocol stack, as shown in Figure 4, it can be divided into the anchor protocol stack (APS) and the fast protocol stack (FPS). The APS supports one or more of the following: control plane functions, low bit rate service, limited coverage, and low reliability transmission. The FPS includes multiple radio processing units (RPUs), and the FPS can support high bit rate service based on multiple RPUs.

[0064] Based on the aforementioned anchor point and fast protocol stack, Figures 5 to 7 illustrate three operating modes of the terminal device. Referring to Figure 5, the terminal device can activate only APS, in which case it is in a low-power state. Referring to Figure 6, the terminal device can activate both APS and FPS, where FPS includes a small number of RPUs (e.g., 4 RPUs). In this mode, the power consumption is higher than that shown in Figure 5, and this type of terminal device can be considered a mainstream terminal device. Referring to Figure 7, the terminal device can activate both APS and FPS, where FPS includes a larger number of RPUs (e.g., 7 RPUs). In this mode, the power consumption is higher than that shown in Figure 6, and this type of terminal device can be considered a high-performance terminal device.

[0065] As mentioned above, some new architectures have been proposed to enable terminal devices to support multiple operating modes (e.g., mode 1 or mode 2), helping to balance energy saving and service transmission requirements. However, these architectural designs remain at the conceptual stage and their usage is not specified, which may lead to inconsistencies in understanding between terminal devices and network devices.

[0066] Therefore, in view of the above problems, this application provides a wireless communication method to specify the functions supported by the terminal device in a first mode or a second mode, so as to unify the understanding of the terminal device and the network device.

[0067] In some implementations, the first mode and the second mode can satisfy one or more of the following: the energy consumed by the terminal device in the first mode is lower than the energy consumed by the terminal device in the second mode, and the transmission performance of the first mode is lower than the transmission performance of the second mode.

[0068] For example, a terminal device operating in the first mode may be in energy-saving mode. As another example, a terminal device operating in the second mode may be in high-performance mode.

[0069] Taking the big.md modem architecture shown in Figure 3 as an example, the first mode can be understood as the terminal device running only the LM. Correspondingly, the second mode can be understood as the terminal device running both the LM and the BM.

[0070] Taking the anchor point + fast protocol stack architecture shown in Figures 4 to 7 as an example, the first mode can be understood as the working mode in which only APS is activated in the terminal device (for example, see Figure 5). Correspondingly, the second mode can be understood as the working mode in which both APS and FPS are activated in the terminal device (for example, see Figure 6). Of course, in the embodiments of this application, the terminal device can activate FPS in both the first mode and the second mode. That is to say, the first mode can be the working mode of the terminal device shown in Figure 6, and correspondingly, the second mode can be the working mode of the terminal device shown in Figure 7.

[0071] In some implementations, the first mode is used to implement a first function of the terminal device related to the control plane; and / or to receive or transmit data at a first rate.

[0072] Taking the first mode for receiving or sending data at a first rate as an example, where the first rate is lower than a rate threshold, receiving or sending data at the first rate can also be referred to as "medium / low rate service data". That is to say, in the first mode, the terminal device can support receiving and / or sending medium rate service data, and / or in the first mode, the terminal device can support receiving and / or sending low rate service data.

[0073] In this application embodiment, the RRC state of the terminal device is not limited. In some implementations, the terminal device can be in an idle state or an inactive state; that is, the first mode supports data reception and / or transmission when the terminal device is in an idle or inactive state. In this case, it can be understood that the inactive small data feature in traditional communication systems (e.g., 5G) can be largely reused in the first mode.

[0074] Taking the first mode as an example of implementing the first function, in some implementations, if the terminal device is in an idle or inactive state, the first function is used for one or more of the following: receiving paging messages; receiving system messages; cell reselection procedure; cell selection procedure; and radio resource management (RRM) measurement. Alternatively, the first function includes one or more of the following: receiving paging messages; receiving system messages; cell reselection procedure; cell selection procedure; and RRM measurement.

[0075] For example, if the terminal device is in an idle or inactive state, the first mode may only support one or more of the following functions: receiving paging messages; receiving system messages; cell reselection procedure; cell selection procedure; RRM measurement.

[0076] In some implementations, if the terminal device is in a connected state, the first function is used for one or more of the following: receiving system messages; cell handover procedures; RRM measurement; and radio link detection. Alternatively, the first function includes one or more of the following: receiving system messages; cell handover procedures; RRM measurement; and radio link detection.

[0077] For example, if the terminal device is in a connected state, the first mode may only support one or more of the following functions: receiving system messages; cell handover procedures; RRM measurement; and radio link detection.

[0078] In some implementations, the second mode is used to implement a second function, which includes one or more of the following: sending or receiving data at a second rate; receiving or sending data for high-reliability and low-latency services; communicating within a first coverage area; and sensing functions.

[0079] Taking the second function of sending or receiving data at a second rate as an example, in some implementations, the second rate is higher than or equal to a rate threshold, wherein the rate threshold can be determined based on the peak rate of the eMBB service, for example, the rate threshold can be equal to the peak rate of the eMBB service. Of course, in the embodiments of this application, sending or receiving data at a second rate may include, for example, transmitting high-rate service data.

[0080] Taking the second function of receiving or sending data for high-reliability and low-latency services as an example, in some implementations, the second function may include supporting high-reliability and low-latency services. In other words, the terminal device that supports the second function can provide the transmission performance required by the 6G network for high-reliability and low-latency services.

[0081] Taking the second function of communicating within the first coverage area as an example, the first coverage area can be greater than the coverage area threshold. That is to say, in the second mode, the terminal device supports the terminal device to communicate with a larger coverage area.

[0082] Taking the second function, which includes the sensing function, as an example, that is to say, the terminal device in the second mode supports sensing services in the sensing scenario.

[0083] Of course, in the embodiments of this application, the second function may include one or more features required by the 6G network.

[0084] The first and second modes in the embodiments of this application have been introduced above. The following section uses the big and small modem architecture shown in Figure 3 as an example to introduce the architecture of the terminal device deploying the big and small modems in the embodiments of this application.

[0085] In some implementations, the terminal device may deploy only the LM, or in other words, the terminal device may deploy the LM independently, as shown in Figure 8A. In this case, the terminal device may operate only in the first mode.

[0086] In some scenarios, the first mode can be understood as a relatively basic working mode. Therefore, terminal devices that only support the first mode can be called "basic user equipment (UE)".

[0087] In some implementations, the terminal device can deploy both an LM and a BM, as shown in Figure 8B. In this case, the terminal device can operate in both a first mode and a second mode, and correspondingly support the aforementioned first and second functions.

[0088] In some scenarios, the second function can be understood as a feature required in 6G networks. Therefore, terminal devices that support both the first and second modes can be called "feature user equipment".

[0089] In some implementations, different features can be implemented using different Business Units (BMs). Referring to Figure 8C, suppose two BMs are deployed in the terminal device. The first BM is used to transmit or receive data at a second rate, and the second BM is used to implement sensing functions. Of course, in this embodiment, multiple BMs can be deployed to implement the same feature. Alternatively, multiple features can be implemented by a single BM.

[0090] As mentioned above, some new architectures have been proposed that have kept the design of terminal devices at the conceptual stage, which may lead to inconsistencies in understanding between terminal devices and network devices.

[0091] Therefore, to address the above-mentioned problems, this application introduces first information in its embodiments, which helps to unify the understanding between terminal devices and network devices. The wireless communication method of this application embodiment is described below with reference to FIG9. The first information of this application embodiment is further described with reference to Examples 1 and 2. The method shown in FIG9 includes step S910.

[0092] In step S910, if the terminal device is operating in target mode, the network device sends first information to the terminal device.

[0093] In some implementations, the target mode mentioned above is either the first mode or the second mode. For an introduction to the first mode and the second mode, please refer to the above text.

[0094] Example 1: The target mode is the first mode, and the first information is used to instruct the terminal device to enable the second mode.

[0095] In some implementations, the terminal device enters the connected state while simultaneously enabling the second mode.

[0096] In some scenarios, the first message is used to instruct the terminal device to activate or start the second mode; the first message is also called the "activation instruction".

[0097] In some implementations, the first information is used to instruct the terminal device to activate the second mode. This can be replaced by instructing the terminal device to wake up the second mode. Taking the second mode implemented via BM as an example, the first information is used to instruct the terminal device to wake up BM.

[0098] In some implementations, the second mode can correspond to one or more different configurations. Accordingly, enabling the second mode on the terminal device can be understood as the terminal device starting to enable one or more of these configurations.

[0099] In some implementations, the aforementioned second mode can correspond to one or more different configurations that can be pre-configured by the network device for the terminal device. For example, the network device can configure the terminal device before the terminal device enables the second mode.

[0100] In some implementations, step S910 includes: when the second mode is off, the network device sends first information to the terminal device. Alternatively, when the first mode is on and the second mode is off, the network device sends first information to the terminal device.

[0101] In some implementations, the first information is indicated via Downlink Control Information (DCI) or Media Access Control (MAC) Control Element (CE). The DCI can be a paging message from the terminal device or control information sent via the downlink control channel. For example, if the terminal device is in an idle or inactive state, the network device can indicate the first information via DCI or MAC CE.

[0102] In this application embodiment, the scheme of indicating the first information via DCI or MAC CE is not limited. In some implementations, DCI or MAC CE may carry one or more bits to indicate the first information (i.e., through explicit indication). Taking DCI or MAC CE carrying one bit as an example, if the value of that bit is a first value, then the first information is used to indicate enabling the second mode. Of course, in this application embodiment, DCI or MAC CE may also implicitly indicate the first information. For example, for a terminal device that supports the second mode, if the terminal device receives DCI or MAC CE, then the terminal device can directly enable the second mode.

[0103] In other implementations, the first information can be carried in dedicated signaling. For example, if the terminal device is in a connected state, the network device can carry the first information by sending dedicated signaling to the terminal device.

[0104] The embodiments of this application can be applied to downlink scenarios. For example, when a network device needs downlink transmission, it can instruct the terminal device to wake up the second mode by sending first information. Of course, the solution of the embodiments of this application can also be applied to uplink scenarios. In this case, the terminal device can request first information by sending a first request to the network device.

[0105] In other words, the above method also includes: the terminal device sending a first request to the network device, the first request being used to request the network device to instruct the terminal device to enable the second mode, or in other words, the first request being used to request the network device to send first information.

[0106] In some implementations, the first request is indicated by an uplink message during the random access procedure initiated by the terminal device. This uplink message can be, for example, message 1 or message 3.

[0107] In this application embodiment, the implementation method of indicating the first request via uplink message is not limited. In some implementations, the message may carry one or more bits to indicate the first request. Taking the message carrying one bit as an example, if the value of the bit is a first value, then the message carries the first request, where the first value can be 0 or 1. Of course, in this application embodiment, the message may also implicitly indicate the first request. For example, it can be pre-agreed that the random access resource for sending the uplink message corresponds to the first request. If the uplink message is transmitted through the random access resource, it indicates that the terminal device indicates the first request via the uplink message.

[0108] In some implementations, the first request is indicated by a message from the terminal device requesting uplink transmission. For example, if the terminal device has uplink data to be transmitted, it sends a message to the network device requesting uplink transmission, which indicates the first request.

[0109] In this application embodiment, the implementation method of indicating the first request via a message is not limited. In some implementations, the message may carry one or more bits to indicate the first request. Taking the message carrying one bit as an example, if the value of the bit is a first value, then the message carries the first request, where the first value can be 0 or 1. Of course, in this application embodiment, the message may also implicitly indicate the first request. For example, for a terminal device supporting the second mode, if the terminal device sends this message, the network device may consider that the message is used to request first information.

[0110] In some implementations, if the terminal device receives the first information, it can activate the second mode. That is, the above method also includes: in response to receiving the first information, the terminal device receives or sends data based on the second mode.

[0111] Example 2: The target mode is the second mode, and the first information is used to instruct the terminal device to turn off the second mode.

[0112] In some implementations, the terminal device enters an idle or disconnected state while disabling the second mode.

[0113] In some scenarios, the first message is used to instruct the terminal device to activate the second mode; therefore, the first message is also called the "deactivation instruction." Taking the second mode implemented through BM as an example, the first message is used to instruct the terminal device to disable BM, or to instruct the terminal device to disable BM so that the corresponding service is terminated, thereby reducing the power consumption of the terminal device.

[0114] In some implementations, the second mode can correspond to one or more different configurations. Accordingly, turning off the second mode on the terminal device can be understood as the terminal device stopping the use of one or more of these configurations.

[0115] In some implementations, step S910 includes: when the terminal device is in the second mode, the terminal device receives first information sent by the network device. Alternatively, if the terminal device is in both the first and second modes, the terminal device receives first information sent by the network device.

[0116] In some implementations, if the first mode is implemented by an LM, the terminal device can receive the first information through the LM. Of course, in this embodiment, if the second mode is implemented by a BM, the terminal device can receive the first information through the BM.

[0117] In this embodiment, the first information may be sent directly from the network device to the terminal device, or the first information may be requested by the terminal device from the network device through a second request. That is, the above method further includes: the terminal device sending a second request to the network device, the second request being used to request the network device to send the first information, or in other words, the second request being used to request the network device to instruct the terminal device to turn off the second mode.

[0118] In some implementations, if the first mode is implemented by the LM, the terminal device can send the second request through the LM. Of course, in this embodiment, if the second mode is implemented by the BM, the terminal device can send the second request through the BM.

[0119] In this implementation, if the terminal device receives the first information, it can disable the second mode. For example, the terminal device can discontinue monitoring data scheduling and possible RRM measurements based on the second mode. Correspondingly, the network device can avoid sending scheduling control signaling and reference signals for the second mode. Taking the second mode implemented through BM as an example, the terminal device can discontinue monitoring data scheduling and possible RRM measurements through BM. Correspondingly, the network device can avoid sending scheduling control signaling and reference signals for BM.

[0120] The foregoing, with reference to Examples 1 and 2, described the scheme by which the network device instructs the terminal device to turn off or on the second mode in embodiments of this application. In embodiments of this application, turning off or on the second mode can be determined autonomously by the terminal device. The following describes the wireless communication method of an embodiment of this application with reference to FIG10. The method shown in FIG10 includes step S1010.

[0121] In step S1010, the terminal device turns the second mode on or off. For an introduction to the second mode, please refer to the above text.

[0122] In some implementations, disabling the second mode can be performed based on the first condition. That is, step S1010 above includes: in response to the first condition, the terminal device disables the second mode.

[0123] In some implementations, the first condition includes the completion of data transmission associated with the second mode and / or the expiration of the first timer.

[0124] Taking the completion of data transmission associated with the second mode as an example, the data associated with the second mode can be understood as data that needs to be transmitted based on the second mode, or data whose transmission requirements match the transmission performance of the second mode. For example, the transmission performance of the second mode supports a higher rate, and the transmission requirement of the data associated with the second mode is also to be transmitted at a higher rate.

[0125] Taking the first condition, including the timeout of the first timer, as an example, the start of the first timer is triggered based on the terminal device enabling the second mode. That is to say, in response to enabling the second mode, the terminal device starts the first timer.

[0126] In some implementations, the first timer is restarted based on one or more of the following triggers: the terminal device receives a scheduling instruction through the second mode; the terminal device receives or sends data with the network device through the second mode.

[0127] Taking the terminal device receiving a scheduling instruction through the second mode as an example, the scheduling instruction can be understood as an instruction sent by the network device to the terminal device to schedule the second mode for data reception or transmission. Generally speaking, if the terminal device receives a scheduling instruction through the second mode, it means that there is data to be transmitted that needs to be received or transmitted through the second mode. Therefore, the first timer can be restarted to avoid the second mode being shut down due to the expiration of the first timer before the data transmission ends, which would cause data transmission failure.

[0128] Taking the terminal device receiving or sending data to the network device through the second mode as an example, generally speaking, if the terminal device receives or sends data through the second mode, it means that the second mode is in working state. Therefore, the first timer can be restarted to avoid the second mode being turned off due to the expiration of the first timer before the data transmission ends, which would cause the data transmission to fail.

[0129] The foregoing described the scheme for the terminal device to autonomously disable the second mode in the embodiments of this application. It should be understood that, in the embodiments of this application, the scheme for the terminal device to autonomously disable the second mode can be used in conjunction with the scheme for the network device to instruct the terminal device to enable the second mode (see the above description of Example 1). Of course, in the embodiments of this application, the scheme for the terminal device to autonomously disable the second mode can be used in conjunction with the scheme for the terminal device to autonomously enable the second mode. The following describes the scheme for the terminal device to autonomously enable the second mode.

[0130] In some implementations, if the transmission requirements of the data to be transmitted in the terminal device match the transmission performance supported by the second mode, the terminal device can activate the second mode. That is, step S1010 includes: activating the second mode in response to the transmission requirements of the data to be transmitted in the terminal device matching the transmission performance supported by the second mode. Here, "the transmission requirements of the data to be transmitted in the terminal device matching the transmission performance supported by the second mode" can be understood as the terminal device being able to meet the transmission requirements of the data to be transmitted in the second mode.

[0131] For example, if the data to be transmitted in the terminal device requires a second rate, and the second mode can transmit data at the second rate, then the terminal device can activate the second mode.

[0132] In some implementations, if the terminal device successfully initiates a random access procedure, the terminal device then activates the second mode. That is, step S1010 above includes: in response to a successful random access procedure, the terminal device activates the second mode.

[0133] In some implementations, the random access procedure can be initiated by the terminal device in the first mode. Of course, in the embodiments of this application, the random access procedure can also be initiated by the terminal device in the second mode.

[0134] The foregoing described the scheme for the terminal device to autonomously enable the second mode in the embodiments of this application. It should be understood that, in the embodiments of this application, the scheme for the terminal device to autonomously enable the second mode can be used in combination with the scheme for the network device to instruct the terminal device to disable the second mode (see the description of Example 2 above).

[0135] In some scenarios, network devices may be unable to determine whether a terminal device's second mode is enabled. In such cases, if the network device directly sends data whose transmission requirements match the second mode to the terminal device, data transmission may fail. For example, after instructing the terminal device to enable the second mode, the network device may be unsure whether the second mode is enabled. If the terminal device has not enabled the second mode, and the network device directly sends data whose transmission requirements match the second mode, data transmission may fail.

[0136] For example, if a terminal device automatically activates the second mode, the network device may not be able to determine whether the second mode is actually enabled. If the terminal device has not activated the second mode, and the network device directly sends data whose transmission requirements match the second mode, data transmission may fail.

[0137] Therefore, to address the aforementioned problems, this application introduces second information. Accordingly, the terminal device can use the second information to indicate to the network device that the second mode has been enabled. That is, the above method further includes: in the second mode, the terminal device sends second information to the network device, the second information being used to indicate that the terminal device has enabled the second mode, or in other words, the second information being used to indicate that the terminal device has activated the second mode.

[0138] In some implementations, the second information is triggered by one or more of the following: the terminal device has uplink information to be sent; the terminal device receives the third information sent by the network device; the terminal device receives the first information sent by the network device.

[0139] Taking uplink information to be sent by a terminal device as an example, in some implementations, the transmission requirements of the uplink information to be sent are matched with the transmission performance supported by the second mode.

[0140] For example, if the transmission requirements of the uplink information to be sent match the transmission performance supported by the second mode, the terminal device can enable the second mode and indicate to the network device that the second mode has been enabled through the second information.

[0141] In this embodiment of the application, the uplink information is not limited. For example, the uplink information may be uplink data and / or uplink control information.

[0142] Taking the terminal device receiving third information sent by the network device as an example, this third information is used to indicate the downlink information to be sent. In some implementations, the transmission requirements of the downlink information are matched with the transmission performance supported by the second mode.

[0143] For example, if the transmission requirements of the downlink information to be sent match the transmission performance supported by the second mode, the network device can instruct the terminal device to enable the second mode (for example, see the description in Example 1). In this case, the terminal device can send a second message to the network device to indicate that the second mode has been enabled so that the network device can send downlink information.

[0144] In this embodiment, the downlink information is not limited. For example, the downlink information may be downlink data and / or downlink control information.

[0145] Taking the terminal device receiving the first information sent by the network device as an example, the first information is used to instruct the terminal device to enable the second mode.

[0146] For example, the network device instructs the terminal device to enable the second mode (see, for example, the description in Example 1). In this case, the terminal device can send a second message to the network device to indicate that the second mode has been enabled so that the network device can send downlink information.

[0147] In this application embodiment, the method of transmitting the second information is not limited. In some implementations, the second information can be indicated by uplink messages during the random access procedure. For example, the second information can be indicated by one or more of the following messages during the random access procedure: message 1, message 3, and message A.

[0148] Furthermore, this application does not limit the method by which the second information is indicated through the aforementioned message. In some implementations, one or more bits in the aforementioned message can indicate the second information, or in other words, the aforementioned message can carry the second information. Wherein, if one or more bits are of a first value, the second information is used to indicate that the terminal device has enabled the second mode. Of course, in this application embodiment, the aforementioned message can implicitly indicate the second information; that is, if the terminal device supports both the first and second modes, after the terminal device sends the aforementioned message, the network device can default to the message indicating that the second mode has been enabled.

[0149] With the widespread application of communication systems, the types of terminal devices included in these systems are increasing, and these different types of terminal devices have different capabilities. Some terminal devices may support both Mode 1 and Mode 2, some may only support Mode 1, and some may not support either Mode 1 or Mode 2. In this case, if network devices do not differentiate between the capabilities of terminal devices and schedule them all in a uniform manner, it may lead to unreasonable scheduling of terminal devices by the network devices.

[0150] Therefore, to address the aforementioned problems, this application also provides a wireless communication method in which a terminal device can send capability information to a network device to indicate whether the terminal device supports a first mode and / or a second mode. Accordingly, the network device can perform scheduling based on the capability information, which helps improve the rationality of scheduling.

[0151] For example, if a terminal device only supports the first mode, it can send second information to the network device to indicate its capabilities. Accordingly, the network device can reselect the terminal device to a dedicated cell (e.g., a low-frequency coverage cell) that supports the first mode.

[0152] For example, if a terminal device only supports the first mode and the second mode, it can send a second message to the network device to indicate its capabilities. Accordingly, the network device can reselect the terminal device to a dedicated cell that supports the second mode.

[0153] For example, if a terminal device only supports the first mode and the second mode, the terminal device can send a second message to the network device to indicate its capabilities. Accordingly, the network device can block the terminal device in a dedicated cell (e.g., a low-frequency coverage cell) for terminal devices that support the first mode.
