The embodiments of the present application describe various embodiments in connection with a terminal device and a network device, wherein: a terminal device may also be called a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, a User device, or the like. The terminal device may be a Station (ST) in a WLAN, may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA) device, a handheld device with wireless communication functionality, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, and a next generation communication system, e.g. a terminal device in an NR network or a terminal device in a future evolved public land mobile network (Public Land Mobile Network, PLMN) network, etc.

By way of example, and not limitation, in embodiments of the present application, the terminal device may also be a wearable device. The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wear by applying wearable technology and developing wearable devices, such as glasses, gloves, watches, clothes, shoes and the like. The wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also can realize a powerful function through software support, data interaction and cloud interaction. The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.

The network device may be a device for communicating with the mobile device, the network device may be an Access Point (AP) in WLAN, a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, or a relay station or an Access Point, or a vehicle device, a wearable device, and a network device in NR network or a base station (gNB) or a network device in future evolved PLMN network, etc.

In the embodiment of the present application, the network device provides services for a cell, and the terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource, or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell (SMALL CELL), and the small cell may include: urban cells (Metro cells), micro cells (Micro cells), pico cells (Pico cells), femto cells (Femto cells) and the like, and the small cells have the characteristics of small coverage area and low transmitting power and are suitable for providing high-rate data transmission services.

For power saving of the terminal device, a DRX transmission mechanism is introduced, and discontinuous reception of signals in the time domain is achieved through semi-static configuration. In the absence of data transmission, power consumption may be reduced by stopping receiving the PDCCH (which would stop PDCCH blind detection 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 fig. 2, the DRX cycle consists of an active period (ACTIVE TIME) during which the terminal device listens and receives the PDCCH, and an inactive or sleep period (Opportunity for DRX); during the inactive period or the sleep 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 RRC idle state (idle) where the DRX cycle is the period of paging messages.

Note that Opportunity for DRX is an inactive period or a sleep period of DRX.

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

The terminal device starts a DRX duration timer (onduration timer) every DRX cycle, listens to the PDCCH during DRX onduration timer operation, and starts an inactivity timer (INACTIVITY TIMER) if the terminal device detects a C-RNTI scrambled PDCCH. The C-RNTI scrambled PDCCH is received again during INACTIVITY TIMER operation, and the terminal device resets INACTIVITY TIMER.

DRX onduration timer and INACTIVITY TIMER are run periods constituting DRX active periods.

Although the network equipment configures a DRX mechanism for the terminal equipment, the terminal equipment is only scheduled opportunistically when on duration appears periodically, and even if the service load of the terminal equipment is very low, the terminal equipment can be scheduled in only a few DRX periods; for paging messages employing the DRX mechanism, the terminal device receives fewer occasions for paging messages. Therefore, after the terminal device configures the DRX mechanism, there are still a plurality of PDCCH detections in on duration, and no data scheduling is detected, and if the terminal device blindly detects the PDCCH when there is no data scheduling, the detected power waste is wasted. There is therefore still further room for optimization for current DRX mechanisms.

Introducing a DRX enhancement mechanism into the projects of 5G and LTE evolution, and if the network equipment judges that the terminal equipment needs to be scheduled in a DRX on duration, sending an energy-saving signal to the terminal equipment, wherein the energy-saving signal is used for waking up the terminal equipment, so that the terminal equipment is started DRX onduration timer in a DRX period, and PDCCH detection is carried out; otherwise, DRX onduration timer is not started, i.e., PDCCH detection is not performed. If the network device determines that the terminal device does not need to be scheduled in the DRX on duration, the network device may indicate to the terminal device that the terminal does not perform PDCCH detection in the DRX on duration.

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

The energy saving scheme devised by the present application against the above technical problems is described in detail below.

Fig. 3 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the application, as shown in fig. 3, the method 200 may include some or all of the following:

s210, detecting an energy-saving signal by a terminal device;

S220, in case the terminal device does not detect the power saving signal, the terminal device determines that the terminal device is operating in dormant BWP or non-dormant BWP on the first secondary cell.

In the embodiment of the present application, the terminal device may not successfully detect the power saving signal for various reasons, for example, due to instantaneous channel quality degradation (due to channel fading) when the terminal device receives the power saving signal, or due to insufficient resources of the network device when transmitting the power saving signal, so that the power saving signal cannot be transmitted.

For example, when the power save signal employs a control channel based on error correction coding, the terminal device detects whether a cyclic redundancy check (Cyclic Redundancy Check, CRC) of the power save signal is successful; if the CRC is successful, the energy-saving signal is considered to be detected; if the CRC fails, the power saving signal is deemed not to be detected.

It should be appreciated that CRC success may also be referred to as CRC correctness, and CRC failure may also be referred to as CRC error.

It should be noted that, the first secondary cell may be any secondary cell in the at least one secondary cell of the terminal device, where the step S220 is described by taking the first secondary cell as an example only, and of course, the terminal device may also determine that the terminal device is operating in the dormant BWP or the non-dormant BWP on the at least one secondary cell, respectively, if the terminal device does not detect the power saving signal, which is not limited by the present application.

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

Alternatively, the step S210 may specifically be:

the terminal device detects the power saving signal during a non-active period of DRX.

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

Optionally, the power saving signal carries secondary cell dormancy indication information, where the secondary cell dormancy indication information is used to instruct the terminal device to switch from dormant BWP to non-dormant BWP and/or from non-dormant BWP to dormant BWP on at least one secondary cell, or the secondary cell dormancy indication information is used to instruct the terminal device to operate in dormant BWP or non-dormant BWP on at least one secondary cell, where the first secondary cell belongs to the at least one secondary cell.

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

Optionally, if the terminal device is operating on the dormant BWP on the first secondary cell, the terminal device does not monitor PDCCH on the dormant BWP of the first secondary cell, and only performs related operations such as Channel State Information (CSI) measurement, automatic gain control (Auto gain control, AGC), beam management (beam management), radio resource management (Radio Resource Management, RRM) measurement, and the like. It should be noted that, the network device configures the dormant BWP on the first secondary cell in advance.

Optionally, the power saving signal further carries wake-up indication information, where the wake-up indication information is used to wake up the terminal device to monitor the PDCCH.

For example, waking up the terminal device starts a DRX duration timer (on duration timer) to listen to the PDCCH.

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

Optionally, the power saving signal is downlink control information (Downlink Control Information, DCI) carried in the PDCCH.

For example, the power saving signal is a DCI format (format) 3_0.

It should be noted that the following advantages are achieved by using the PDCCH to carry the power saving signal:

1. The PDCCH design can be directly multiplexed, including aspects of coding, scrambling, resource mapping, search space, control resource set (Control Resource Set, CORESET) and the like, so that the standardized workload is smaller;

2. The PDCCH has good compatibility with other signal transmissions and multiplexing characteristics with other channels such as the physical downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH) since the system already supports the PDCCH channel.

Alternatively, one PDCCH may carry one or more power saving signals of the terminal device.

Alternatively, the power saving signal may be a sequence-based signal, or other signal.

Alternatively, as example 1, the terminal device determines that the terminal device is operating in a dormant BWP or a non-dormant BWP on the first secondary cell according to the first or second manner.

Optionally, the first mode includes at least one of:

If the non-dormant BWP is operated, the non-dormant BWP is maintained;

If operating in dormant BWP, switch from dormant BWP to non-dormant BWP.

That is, in example 1, the determining by the terminal device that the terminal device is operating in the dormant BWP or the non-dormant BWP on the first secondary cell according to the first mode may specifically be:

if the terminal equipment works on the first auxiliary cell and is not in the dormant BWP, determining that the terminal equipment is kept in the non-dormant BWP on the first auxiliary cell; or alternatively

If the terminal device is operating in dormant BWP on the first secondary cell, it is determined that the terminal device is handed over from dormant BWP to non-dormant BWP on the first secondary cell.

Optionally, the second mode includes at least one of:

if operating in non-dormant BWP, then remain in non-dormant BWP or switch from non-dormant BWP to dormant BWP.

If working in dormant BWP, then remain in dormant BWP.

That is, in example 1, the determining by the terminal device that the terminal device is operating in the dormant BWP or the non-dormant BWP on the first secondary cell according to the second manner may specifically be:

If the terminal device is operating in non-dormant BWP on the first secondary cell, determining that the terminal device remains in non-dormant BWP or switches from non-dormant BWP to dormant BWP on the first secondary cell;

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

It should be noted that, if the terminal device determines that the terminal device is operating in the dormant BWP or the non-dormant BWP on the first secondary cell according to the second mode, in order to achieve the maximum energy saving, the terminal device may stay in the dormant BWP on the first secondary cell until the terminal device is handed over from the dormant BWP to the non-dormant BWP after receiving the instruction of the network to instruct to switch to the non-dormant 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 operating in a dormant BWP or a non-dormant BWP on the first secondary cell according to the first mode or the second mode; and the terminal equipment determines that the terminal equipment works in the dormant BWP or the non-dormant BWP on the first secondary cell according to the first mode or the second mode according to the first indication information.

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, medium access control element (MEDIA ACCESS Control Control Element, MAC CE) signaling.

For example, one bit of higher layer signaling is used as the first indication information. For example, a bit value of "1" indicates a first mode, and a bit value of "0" indicates a second mode.

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

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

Alternatively, the default manner of pre-configuration may be protocol-agreed, or the pre-configuration signaling may be pre-configured or indicated for the network device.

Alternatively, in example 1, if the configuration information for whether the terminal device wakes up in the case that the power saving signal is not detected is not configured in the terminal device, for example, the terminal device determines that the terminal device operates in the dormant BWP or the non-dormant BWP on the first secondary cell according to the aforementioned default manner of pre-configuration.

Alternatively, as example 2, the terminal device determines whether the terminal device is operating in dormant BWP or non-dormant BWP on the first secondary cell, depending on whether the terminal device wakes up.

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

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

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

Optionally, in example 2, the terminal device determines that the terminal device is operating in dormant BWP or non-dormant BWP on the first secondary cell according to whether the terminal device wakes up, including at least one of:

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

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 is switched 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 operating in non-dormant BWP on the first secondary cell, the terminal device determines that the terminal device remains in non-dormant BWP or switches from non-dormant BWP to dormant BWP on the first secondary cell;

If the terminal device does not wake up and the terminal device is operating in dormant BWP on the first secondary cell, the terminal device determines that the terminal device remains in 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 if the power saving signal is not detected; and the terminal equipment determines whether the terminal equipment wakes up according to the first configuration information.

Alternatively, in example 2, if the terminal device wakes up, the terminal device listens to the PDCCH. Further, if the terminal device wakes up, the terminal device starts a DRX duration timer (on duration timer) in a DRX cycle to monitor a PDCCH scrambled by a cell radio network temporary identifier (Cell Radio Network Temporary Identity, C-RNTI).

Optionally, in example 2, if the first configuration information is configured, the terminal device determines whether the terminal device is operating in dormant BWP or non-dormant BWP on the first secondary cell according to whether the terminal device wakes up, where the first configuration information is used to configure whether the terminal device wakes up if the power saving signal is not detected.

That is, in example 2, when the power saving signal is not detected, the terminal device operates in or switches to 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 point, if the terminal device wakes up, for example, after a power-saving signal, the DRX cycle starts a DRX duration timer (on duration timer) to listen to the PDCCH scrambled by the cell radio network temporary identifier (Cell Radio Network Temporary Identity, C-RNTI), then the terminal needs to stay in non-dormant BWP or switch to non-dormant BWP (depending on whether the terminal is currently in dormant BWP or not).

If the terminal remains dormant (i.e., if the terminal does not wake up), for example, the DRX cycle starts a DRX duration timer (on duration timer) to listen to the C-RNTI-scrambled PDCCH after the power saving signal, then the terminal device needs to stay dormant BWP or switch to dormant BWP at this time (depending on whether the terminal is currently located in non-dormant BWP).

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

Alternatively, the network device may configure the terminal device with different power saving techniques in different situations. For example, there may be at least three cases:

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

case 2: only the sleep BWP-based energy saving technology is configured;

case 3: both the energy saving technology based on whether to wake up and the energy saving technology based on the sleep BWP are configured.

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

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

Thus, in the embodiment of the present application, in the case that the power saving signal is not detected, the terminal device may determine that it operates in dormant BWP or non-dormant BWP on the secondary cell, thereby achieving power saving.

Further, by defining the abnormal processing behaviors in different scenes when the terminal equipment does not detect the energy-saving signal, the terminal has a clear behavior mode, so that the behavior of the network and the behavior of the terminal are kept consistent, and the stability of the network is further ensured. On the other hand, the configurable behavior mode ensures the flexibility of the network, and can adopt different processing methods according to different conditions.

Still further, referring to the processing behavior of the network configuration in the case of wake-up, on the one hand, additional configuration signaling of the network can be saved, and on the other hand, the consistency of the two energy saving techniques is maintained, or energy saving is ensured to the greatest extent, or performance is ensured to the greatest extent.

Fig. 4 is a schematic flow chart of a wireless communication method 300 according to an embodiment of the application, as shown in fig. 4, the method 300 may include some or all of the following:

s310, the network device sends first indication information to the terminal device, where the first indication information is used to indicate that the terminal device determines that the terminal device is working in a dormant BWP or a non-dormant BWP on the first secondary cell according to the first mode or the second mode if the power saving signal is not detected.

For example, when the power saving signal employs a control channel based on error correction coding, the terminal device detects whether the CRC of the power saving signal is successful; if the CRC is successful, the energy-saving signal is considered to be detected; if the CRC fails, the power saving signal is deemed not to be detected.

It should be noted that, the first secondary cell may be any secondary cell in the at least one secondary cell of the terminal device, where the step S310 is described by taking the first secondary cell as an example only, and of course, the terminal device may also determine that the terminal device is operating in the dormant BWP or the non-dormant BWP on the at least one secondary cell, respectively, if the terminal device does not detect the power saving signal, which is not limited by the present application.

Optionally, the first mode includes at least one of:

If the non-dormant BWP is operated, the non-dormant BWP is maintained;

If operating in dormant BWP, switch from dormant BWP to non-dormant BWP.

That is, if the first indication information indicates that the terminal device determines that the terminal device is operating in the dormant BWP or the non-dormant BWP on the first secondary cell according to the first mode, the terminal device may respond as follows:

Optionally, the second mode includes at least one of:

If working in dormant BWP, then remain in dormant BWP.

That is, if the first indication information indicates that the terminal device determines that the terminal device is operating in the dormant BWP or the non-dormant BWP on the first secondary cell according to the second mode, the terminal device may respond as follows:

Optionally, the terminal device receives the first indication information, and 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 first mode or the second mode according to the first indication information.

RRC dedicated signaling, broadcast signaling, MAC CE signaling.

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

It should be noted that, if the terminal device wakes up, the terminal device listens to the PDCCH. Further, if the terminal device wakes up, the terminal device starts a DRX duration timer (on duration timer) in a DRX cycle to monitor the C-RNTI scrambled PDCCH.

Optionally, the power saving signal is DCI carried in PDCCH.
