The embodiments of this application describe various embodiments in conjunction with terminal equipment and network equipment. Among them, terminal equipment may also be referred to as User Equipment (UE), access terminal, subscriber unit, user station, mobile station, mobile station, and remote Station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc. The terminal device can be a station (STAION, ST) in the WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, and personal digital processing (Personal Digital Assistant, PDA) devices, handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, and next-generation communication systems, such as terminal devices in the NR network or Terminal equipment in the public land mobile network (PLMN) network that will evolve in the future.

As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices can also be called wearable smart devices. It is a general term for using wearable technology to intelligently design everyday wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is directly worn on the body or integrated into the user's clothes or accessories. Wearable devices are not only a kind of hardware device, but also realize powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include full-featured, large-sized, complete or partial functions that can be achieved without relying on smart phones, such as smart watches or smart glasses, and only focus on a certain type of application function, and need to cooperate with other devices such as smart phones. Use, such as all kinds of smart bracelets and smart jewelry for physical sign monitoring.

A network device can be a device used to communicate with mobile devices. The network device can be an access point (AP) in WLAN, a base station (BTS) in GSM or CDMA, or a device in WCDMA. A base station (NodeB, NB) can also be an Evolutional Node B (eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device or base station in the NR network ( gNB) or network equipment in the future evolved PLMN network.

In the embodiment of the present application, the network equipment provides services for the cell, and the terminal equipment communicates with the network equipment through the transmission resources (for example, frequency domain resources, or spectrum resources) used by the cell, and the cell may be a network equipment (for example, The cell corresponding to the base station. The cell can belong to a macro base station or a base station corresponding to a small cell. The small cell here can include: Metro cell, Micro cell, Pico Cells, Femto cells, etc. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-rate data transmission services.

For the consideration of power saving of terminal equipment, the DRX transmission mechanism is introduced, and the discontinuous reception signal in the time domain is realized through semi-static configuration. When there is no data transmission, the power consumption can be reduced by stopping receiving the PDCCH (the blind PDCCH detection will be stopped at this time).

Specifically, a DRX cycle (cycle) is configured for a terminal device in a radio resource control (Radio Resource Control, RRC) connected state (RRC_CONNECTED). As shown in Figure 2, the DRX cycle consists of an active period (Active Time) and an inactive period or dormant period (Opportunity for DRX). During the active period, the terminal device monitors and receives the PDCCH; in the inactive period or dormant period, The terminal device does not receive the PDCCH to reduce power consumption. In addition, the transmission of paging messages is also a DRX mechanism in the RRC idle state. At this time, the DRX cycle is the cycle of the paging message.

It should be noted that Opportunity for DRX is the inactive period or dormant period of DRX.

As shown in Figure 2, it is divided into successive DRX cycles in the time domain.

In each DRX cycle, the terminal device starts the DRX onduration timer. During the DRX onduration timer, the terminal device monitors the PDCCH. If the terminal device detects the C-RNTI scrambled PDCCH, the terminal device starts the inactivity timer (Inactivity timer). Timer). When the PDCCH scrambled by the C-RNTI is received again during the operation of the Inactivity Timer, the terminal device resets the Inactivity Timer.

The DRX onduration timer and the inactivity timer constitute the DRX activation period.

Although the network equipment configures the DRX mechanism for the terminal equipment, the terminal equipment is only scheduled opportunistically during the periodical on duration. Even when the terminal equipment’s business load is very low, the terminal equipment only has a few DRX cycles to get it. Scheduling: For paging messages that use the DRX mechanism, the terminal device has fewer opportunities to receive the paging message. Therefore, after the terminal device is configured with the DRX mechanism, there are still most on-duration PDCCH detections and the data scheduling is not detected. If the terminal device blindly detects the PDCCH when there is no data scheduling, the detected power is wasted. Therefore, there is room for further optimization for the current DRX mechanism.

In 5G and LTE evolution projects, the DRX enhancement mechanism is introduced. When the network device determines that it needs to schedule the terminal device during DRX on duration, it sends an energy-saving signal to the terminal device. The energy-saving signal is used to wake up the terminal device so that the terminal device is in the DRX cycle DRX onduration timer is activated to perform PDCCH detection; otherwise, DRX onduration timer is not activated, and PDCCH detection is not performed. If the network device determines that it is not necessary to schedule the terminal device in DRX on duration, it can indicate to the terminal device that the terminal does not perform PDCCH detection during the on duration of DRX.

However, it is not configured how the terminal device responds without receiving an energy-saving signal.

The following describes in detail the energy-saving solution designed by this application in response to the above technical problems.

FIG. 3 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 3, the method 200 may include some or all of the following contents:

S210: The terminal device detects the energy-saving signal;

S220: In the case that the terminal device does not detect the energy-saving signal, the terminal device determines that the terminal device works in the dormant BWP or the non-dormant BWP on the first secondary cell.

In the embodiment of the present application, the terminal device may not be able to successfully detect the energy-saving signal due to various reasons, for example, due to the instantaneous channel quality deterioration when the terminal device receives the energy-saving signal (due to channel fading), or because the network device is transmitting Insufficient resources during energy-saving signals make it impossible to send energy-saving signals.

For example, when the energy-saving signal uses a control channel based on error correction coding, the terminal device detects whether the cyclic redundancy check (CRC) of the energy-saving signal is successful; if the CRC is successful, it is considered that the energy-saving signal is detected ; If the CRC fails, it is considered that the energy-saving signal is not detected.

It should be understood that CRC success can also be referred to as CRC correct, and CRC failure can also be referred to as CRC error.

It should be noted that the first secondary cell may be any one of the at least one secondary cell of the terminal device. The above step S220 is only described by taking the first secondary cell as an example. Of course, the terminal device does not detect In the case of the energy-saving signal, the terminal device may also determine that the terminal device is working in a dormant BWP or a non-dormant BWP on the at least one secondary cell, which is not limited in this application.

In addition, the first secondary cell may also be a secondary cell in a secondary cell group of the terminal device, and a bit in the energy-saving signal is used to indicate that the secondary cell of the secondary cell group works in a dormant BWP or a non-dormant BWP.

Optionally, the foregoing step S210 may specifically be:

The terminal device detects the energy-saving signal during the inactive period of DRX.

In the above step S210, the terminal device detects the energy-saving signal sent by the network device during the inactive period of DRX.

In the embodiment of the present application, the secondary cell may be a cell arranged on the secondary carrier. In some scenarios, the energy saving signal may also be referred to as a wake-up signal (Wake-up signal, WUS).

Optionally, if the terminal device works in the dormant BWP on the first secondary cell, the terminal device does not monitor the PDCCH on the dormant BWP of the first secondary cell, and only performs channel state information (Channel State Information, CSI) measurement, automatic gain control (Auto gain control, AGC), beam measurement (beam management), radio resource management (Radio Resource Management, RRM) measurement and other related operations. It should be noted that the network device has configured the dormant BWP on the first secondary cell in advance.

Optionally, the energy-saving signal also carries wake-up indication information, and the wake-up indication information is used to wake up the terminal device to monitor the PDCCH.

For example, wake up the terminal device to start a DRX duration timer (on duration timer) to monitor the PDCCH.

Further, if the terminal device wakes up, the terminal device starts a DRX duration timer (on duration timer) in the DRX cycle to monitor the PDCCH scrambled by the Cell Radio Network Temporary Identity (C-RNTI).

Optionally, the energy saving signal is Downlink Control Information (DCI) carried in the PDCCH.

For example, the energy saving signal is in the DCI format (format) 3_0.

It should be noted that using PDCCH to carry energy-saving signals has the following advantages:

1. PDCCH design can be reused directly, including coding, scrambling, resource mapping, search space, control resource set (CORESET), etc., so the standardized workload is small;

2. It has good compatibility with other signal transmission and multiplexing characteristics. Since the system already supports PDCCH channel, PDCCH and other channels such as Physical Downlink Shared Channel (PDSCH) have good compatibility with multiplexing characteristics. .

Optionally, one PDCCH may carry energy-saving signals of one or more terminal devices.

Optionally, the energy-saving signal may also be a sequence-based signal or other signals.

If the terminal device works in the dormant BWP on the first secondary cell, it is determined that the terminal device remains in the dormant BWP on the first secondary cell.

It should be noted that, if the terminal device determines that the terminal device is working in the dormant BWP or the non-dormant BWP on the first secondary cell according to the second method, in order to maximize energy saving, the terminal device is in the first secondary cell It can stay in the dormant BWP until the terminal device switches from the dormant BWP to the non-dormant BWP after receiving an instruction from the network to switch to the non-sleep BWP.

Optionally, in Example 1, the terminal device receives first indication information, where the first indication information is used to instruct the terminal device to determine that the terminal device is on the first secondary cell according to the first mode or the second mode Working in a dormant BWP or a non-dormant BWP; and the terminal device determines according to the first method or the second method according to the first indication information that the terminal device is working in the dormant BWP or the non-dormant BWP on the first secondary cell .

Optionally, the first indication information is carried in at least one of the following signaling:

Radio Resource Control (Radio Resource Control, RRC) dedicated signaling, broadcast signaling, and Media Access Control Control Element (MAC CE) signaling.

For example, one bit in the high-level signaling is used as the first indication information. For example, a value of "1" for this bit indicates the first mode, and a value of "0" for this bit indicates the second mode.

Optionally, in Example 1, if the first indication information is not received, the terminal device by default determines that the terminal device is working in the dormant BWP on the first secondary cell according to the first mode or the second mode. Or non-sleeping BWP.

Optionally, in Example 1, the terminal device determines to work in the dormant BWP or non-dormant BWP on the first secondary cell according to the first mode or the second mode according to a pre-configured default mode. .

Optionally, the pre-configuration default mode may be agreed upon by the protocol, or the pre-configuration signaling is pre-configured or instructed by the network device.

Optionally, in Example 1, if the terminal device is not configured with configuration information for whether the terminal device wakes up when the energy-saving signal is not detected, for example, the terminal device determines according to the aforementioned pre-configured default mode. The first way or the second way determines that the terminal device works in the dormant BWP or the non-dormant BWP on the first secondary cell.

Optionally, as example 2, according to whether the terminal device wakes up, the terminal device determines that the terminal device works in a dormant BWP or a non-dormant BWP on the first secondary cell.

Optionally, in Example 2, if the terminal device wakes up, the terminal device determines that the terminal device remains in the non-dormant BWP on the first secondary cell or switches from the dormant BWP to the non-dormant BWP; or,

If the terminal device does not wake up, the terminal device determines that the terminal device remains in the dormant BWP on the first secondary cell or switches from a non-dormant BWP to a dormant BWP.

Optionally, the terminal device may also determine whether the terminal device wakes up according to the default configuration.

Optionally, in Example 2, according to whether the terminal device is awake, the terminal device determines that the terminal device is working in a dormant BWP or a non-dormant BWP on the first secondary cell, including at least one of the following:

If the terminal device wakes up and the terminal device works in a non-sleeping BWP on the first secondary cell, the terminal device determines that the terminal device remains in the non-sleeping BWP on the first secondary cell;

If the terminal device wakes up and the terminal device works in the dormant BWP on the first secondary cell, the terminal device determines that the terminal device switches from the dormant BWP to the non-dormant BWP on the first secondary cell;

If the terminal device does not wake up and the terminal device is working in a non-sleeping BWP on the first secondary cell, the terminal device determines that the terminal device remains in a non-sleeping BWP on the first secondary cell or switches from a non-sleeping BWP to a dormant BWP BWP;

If the terminal device does not wake up and the terminal device works in the dormant BWP on the first secondary cell, the terminal device determines that the terminal device remains in the dormant BWP on the first secondary cell.

Optionally, in Example 2, the terminal device receives first configuration information, where the first configuration information is used to configure whether the terminal device wakes up when the energy-saving signal is not detected; and the terminal device according to the first configuration Information to determine whether the terminal device wakes up.

Optionally, in Example 2, if the terminal device wakes up, the terminal device monitors the PDCCH. Further, if the terminal device wakes up, the terminal device starts a DRX duration timer (on duration timer) in the DRX cycle to monitor the PDCCH scrambled by the Cell Radio Network Temporary Identity (C-RNTI).

Optionally, in Example 2, if the first configuration information is configured, according to whether the terminal device wakes up, the terminal device determines that the terminal device is working in a dormant BWP or a non-dormant BWP on the first secondary cell, where the The first configuration information is used to configure whether the terminal device wakes up when the energy-saving signal is not detected.

That is to say, in Example 2, when the energy saving signal is not detected, the terminal device works in the dormant BWP or switches to the dormant BWP on the secondary cell, which may depend on the behavior of the terminal device "whether to wake up" in this case.

At this time, if the terminal device wakes up, for example, after the energy-saving signal, the DRX cycle starts the DRX duration timer (on duration timer) to monitor the PDCCH scrambled by the Cell Radio Network Temporary Identity (C-RNTI), then this The terminal needs to remain in a non-dormant BWP or switch to a non-dormant BWP (depending on whether the terminal is currently in a dormant BWP).

At this time, if the terminal stays dormant (that is, if the terminal does not wake up), for example, the DRX cycle does not start the DRX on duration timer after the energy saving signal to monitor the PDCCH scrambled by C-RNTI, then the terminal device needs to stay dormant at this time BWP or switch to a dormant BWP (depending on whether the terminal is currently in a non-dormant BWP).

Therefore, the terminal device determines whether the terminal device is working in a dormant BWP or a non-dormant BWP based on the configuration of the processing behavior of the terminal device when the power saving signal is not detected by the network device.

Optionally, in different situations, the network device may configure the terminal device with different energy-saving technologies. For example, there may be at least the following three situations:

Case 1: Only the energy-saving technology based on whether to wake up is configured;

Case 2: Only the energy-saving technology based on dormant BWP is configured;

Case 3: Both the energy-saving technology based on whether to wake up and the energy-saving technology based on dormant BWP are configured.

In case 2, the terminal device may determine to work in the dormant BWP or switch to the dormant BWP on the secondary cell based on the above example 1.

In case 3, the terminal device may determine to work in the dormant BWP or switch to the dormant BWP on the secondary cell based on the above example 2. Of course, at this time, the terminal device may also determine to work in the dormant BWP or switch to the dormant BWP on the secondary cell based on the above example 1.

Therefore, in the embodiment of the present application, in the case that the energy saving signal is not detected, the terminal device can determine that it is working in the dormant BWP or the non-dormant BWP on the secondary cell, thereby achieving energy saving.

Furthermore, by defining abnormal handling behaviors when the terminal device does not detect an energy-saving signal in different scenarios, the terminal has a clear behavior mode, which is conducive to keeping the behavior of the network and the terminal consistent, thereby ensuring the stable performance of the network. On the other hand, the configurable behavior mode ensures the flexibility of the network, and different processing methods can be used according to different situations.

Furthermore, referring to the processing behavior of the network configuration in the case of whether to wake up, on the one hand, it can save additional configuration signaling of the network, on the other hand, it can maintain the consistency of the two energy-saving technologies, or guarantee energy saving to the greatest extent, or Guarantee performance.
