Technical field

This application relates to the field of wireless communication technology, and in particular to a communication method and terminal equipment.

Background technique

In the existing long-term evolution (LTE) system and new radio (NR) system, user equipment (UE) performs physical downlink control channel (physical downlink control channel, PDCCH) detection. The consumption is very large. But in reality, data transmission is usually bursty. For example, there is data transmission within a period of time, and there is no data transmission for a longer period of time after the data transmission. Therefore, most of the PDCCH detections performed by the UE fail to detect any indication.

Based on this, both the LTE system and the NR system have introduced discontinuous reception (DRX) technology. The network device indicates the DRX cycle to the UE. In a DRX cycle, the UE performs PDCCH detection during the active time, and sleeps during the time except the active time, thereby reducing the power consumption of the UE.

However, when the UE performs PDCCH detection during the activation time, data transmission is often bursty and sparse, and there is a high probability that there is no data transmission demand. As a result, a large proportion of detected PDCCHs have no indication and still cause power consumption. Waste. At the same time, in the NR system, the UE will work in a larger radio frequency and baseband bandwidth, and the power consumption of the UE will be higher. Based on this, a power saving signal (PoSS) is introduced in the NR system to further reduce the power consumption of the UE. That is, before the network device indicates the DRX cycle to the UE, it sends a PoSS signal to the UE to indicate whether the UE needs to wake up in the next one or more DRX cycles for PDCCH detection, and/or receive the physical downlink shared channel. , PDSCH), and/or measurement report.

Generally speaking, due to the signal attenuation and the movement and rotation of the UE during the PoSS transmission process, it is easy to cause the missed detection or false detection of the PoSS, which may lead to waste of power consumption.

Summary of the invention

The present application provides a communication method and terminal equipment to avoid waste of power consumption due to missed detection or false detection of PoSS in the prior art.

In the first aspect, an embodiment of the present application provides a communication method. This method can be executed by the terminal device. In this method, the terminal device can receive a power saving signal (PoSS). The PoSS signal can be a sequence signal or a data signal. If it is a data signal, it may be downlink control information (DCI), which is carried in a physical downlink control channel (PDCCH). It may also be a media access control element (MAC-CE) signal, or it may also be a radio resource control (radio resource control, RRC) signal. The PoSS signal is used to instruct the terminal device to sleep or wake up in the first discontinuous reception (DRX) period. For example, if the PoSS signal is a sleep signal (go to sleep signal, GTS), the PoSS signal is used to instruct the terminal device to sleep in the first DRX cycle. If the PoSS signal is a wake-up signal (Wake up signal, WUS), then the PoSS signal is used to instruct the terminal device to sleep in the first DRX cycle. The PoSS signal is used to instruct the terminal device to wake up in the first DRX cycle. In this application, when the signal quality of the PoSS signal is less than or equal to the first threshold, the terminal device can perform the following operations: the terminal device can wake up in the first DRX cycle; or, if the terminal device wakes up in the second DRX cycle, Then the terminal device also wakes up in the first DRX cycle. Or, if the terminal device sleeps in the second DRX cycle, the terminal device also sleeps in the first DRX cycle. The second DRX cycle may be the previous DRX cycle of the first DRX cycle.

Based on this solution, when the signal quality of the PoSS signal is less than the first threshold, the terminal device may not be able to accurately demodulate the PoSS signal to obtain an indication of the network device, and the terminal device can wake up directly in the first DRX cycle, or according to the first DRX cycle. The wake-up or sleep state of the terminal device in the previous DRX cycle of a DRX cycle wakes up or sleeps in the first DRX cycle, which can save the power consumption of the terminal device, and can also reduce the data scheduling delay caused by the missed PoSS signal detection .

In a possible implementation manner, when the signal quality of the PoSS signal is greater than the first period, the terminal device may sleep or wake up in the first DRX period according to the instruction of the PoSS signal. For example, when the PoSS signal is a WUS signal, the terminal device wakes up in the first DRX cycle, and when the PoSS signal is a GTS signal, the terminal device sleeps in the first DRX cycle.

Based on this solution, when the signal quality of the PoSS signal is greater than the first threshold, the terminal device wakes up or sleeps in the first DRX cycle according to the instruction of the PoSS signal.

In a possible implementation manner, the terminal device may receive the PoSS signal in the manner of diversity reception. Generally, a terminal device based on the MIMO protocol may have x transmitting antennas and y receiving antennas. Among them, x and y are natural numbers. The terminal device can determine the receive diversity parameters when receiving the PoSS signal. The receiving diversity parameter includes the index of at least one receiving antenna and the signal delay on the corresponding receiving antenna. The terminal device may receive the PoSS signal on the at least one receiving antenna based on the corresponding signal delay according to the index of the at least one receiving antenna and the signal delay. For example, the receiving diversity parameter may be receiving antenna 3 and signal time delay a, and receiving antenna 4 and signal time delay b. Then, the terminal device can receive the PoSS signal on the receiving antenna 3 based on the corresponding signal delay a and on the receiving antenna 4 based on the corresponding signal delay b.

Based on this solution, the terminal device can use multiple antenna diversity to receive PoSS signals according to the receive diversity parameters, thereby improving the robustness of PoSS signal reception.

In a possible implementation manner, the terminal device may determine the reception diversity parameter according to the second parameter. The second parameter here may include at least one of the following: the moving speed of the terminal device, the sleep time of the terminal device, and the distance of the terminal device from the serving base station. Wherein, the sleep time of the terminal device may be the accumulated sleep time of the terminal device for a specified period of time. The designated duration may be preset according to an empirical value, or the designated duration may also be the accumulated duration from the most recent sleep before the first DRX cycle to the current time. For example, if the terminal device sleeps in the second DRX cycle, the sleep time of the terminal device may be the accumulated sleep time from the sleep time of the terminal device in the second DRX cycle to the current time.

Based on this solution, the terminal device can determine the reception diversity parameter when receiving the PoSS signal according to its own parameters, so that the reception robustness of the PoSS signal can be further improved.

In a possible implementation manner, the terminal device may receive the PoSS signal after the end of the second DRX cycle dormancy or after detecting the end of the physical downlink control channel, and before the arrival of the first DRX cycle, or the terminal device may receive the PoSS signal in the first DRX cycle. At the beginning of the cycle, the PoSS signal is received.

Based on this solution, the terminal device and the network device can pre-determine the time to receive the PoSS signal, and receive the PoSS signal at the determined time, which can reduce the waste of power consumption caused by the frequent detection of the PoSS signal by the terminal device.

In the second aspect, the embodiment of the present application also provides another communication method. This method can be executed by the terminal device. In this method, when the terminal device does not receive the PoSS signal for instructing the terminal device to sleep or wake up in the first DRX cycle, the terminal device can determine whether the terminal device receives the PoSS signal according to the preset receiving mode when the terminal device receives the PoSS signal. Sleep or wake up in the first DRX cycle. Among them, the receiving mode may include an omnidirectional beam receiving mode or a directional beam receiving mode.

Based on this solution, when the terminal device does not receive the PoSS signal, the terminal device can sleep or wake up in the first DRX cycle according to the receiving mode when receiving the PoSS signal. The terminal device does not need to detect the PoSS signal in real time, which can save the terminal equipment Power consumption can also reduce the data scheduling delay caused by the missed PoSS signal detection.

In a possible implementation manner, when the receiving mode is the omni-beam receiving mode, the terminal device may perform the following operations: the terminal device may add 1 to the recorded total number of times that the PoSS signal is not received. The total number of times may be calculated when the terminal device enters the DRX mode, and cleared when the terminal device exits the DRX mode. If the current total number of times of adding 1 processing is less than the first specified value, and the displacement of the terminal device is less than or equal to the second specified value, the terminal device can sleep in the first DRX cycle, or in the first DRX cycle and in the first DRX cycle. All the n DRX cycles after one DRX cycle go to sleep. Among them, n is a natural number. The displacement here may be the displacement between the first position of the terminal device and the second position of the terminal device. The first position may be the position where the terminal device receives the PoSS signal corresponding to the second DRX cycle, and the second position may be the position where the terminal device receives the PoSS signal corresponding to the first DRX cycle. The second DRX cycle may be the previous DRX cycle of the first DRX cycle. If the current total number of times of adding 1 processing is greater than or equal to the first specified value, the terminal device can wake up in the first DRX cycle and send the first parameter to the network device. The first parameter here is used by the terminal device to request the network device to exit the DRX mode.

Based on this solution, when the terminal device receives the PoSS signal according to the omnidirectional beam reception mode but does not receive the PoSS signal, it can be determined to sleep in the first DRX cycle according to the total number of times that the PoSS signal is not received and the displacement of the terminal device Or wake up.

In a possible implementation manner, when the receiving mode is the directional beam receiving mode, the terminal device may perform the following operations: the terminal device may add 1 to the recorded total number of times that the PoSS signal is not received. If the total number of times after adding 1 is less than the third specified value, and the displacement of the terminal device is less than or equal to the fourth specified value, and the rotation angle of the terminal device is less than the fifth specified value, the terminal device can sleep in the first DRX cycle Or, the dormancy may be performed both in the first DRX cycle and m DRX cycles after the first DRX cycle. Among them, m is a natural number. The displacement may be the displacement of the first position of the terminal device and the second position of the terminal device. The first position may be the position where the terminal device receives the PoSS signal corresponding to the second DRX cycle, and the second position may be the position where the terminal device receives the PoSS signal corresponding to the first DRX cycle. The second DRX cycle may be the previous DRX cycle of the first DRX cycle. The rotation angle is the difference between the angle when the terminal device is in the first position and the angle when it is in the second position. If the total number of times after adding 1 processing is less than the third specified value, and the displacement of the terminal device is greater than the fourth specified value, the terminal device can wake up in the first DRX cycle. If the total number of times after adding 1 processing is greater than or equal to the third specified value, the terminal device can wake up in the first DRX cycle and send the first parameter to the network device. The first parameter here is used by the terminal device to request the network device to exit the DRX mode.

Based on this solution, when the terminal device does not receive the PoSS signal according to the directional beam receiving method, it can determine to sleep or wake up in the first DRX cycle according to the total number of times that the PoSS signal is not received, the displacement and rotation angle of the terminal device .

In a possible implementation manner, the terminal device may receive the PoSS signal after the end of sleep in the second DRX cycle or after detecting the end of the physical downlink control channel, and before the arrival of the first DRX cycle, or the terminal device may receive the PoSS signal in the first DRX cycle. At the beginning of the DRX cycle, the PoSS signal is received.

Based on this solution, the terminal device and the network device can pre-determine the time to receive the PoSS signal, and receive the PoSS signal at the determined time, which can reduce the waste of power consumption caused by the frequent detection of the PoSS signal by the terminal device. If the terminal device does not receive the PoSS signal at the determined time, it can determine whether to sleep or wake up in the first DRX cycle according to the method provided in this application.

In the technical solutions provided in the embodiments of the present application, the device used to implement the functions of the terminal is an example to describe the technical solutions provided in the embodiments of the present application.

To facilitate the understanding of the embodiments of the present application, first, the communication system shown in FIG. 1 is taken as an example to describe in detail the communication system applicable to the embodiments of the present application. Fig. 1 shows a schematic diagram of a communication system suitable for the communication method of the embodiment of the present application. As shown in FIG. 1, the communication system 100 includes a network device 102 and a terminal device 106. The network device 102 may be configured with multiple antennas, and the terminal device 106 may also be configured with multiple antennas. Optionally, the communication system may further include a network device 104, and the network device 104 may also be configured with multiple antennas.

It should be understood that the network device 102 or the network device 104 may also include multiple components related to signal transmission and reception (for example, a processor, a modulator, a multiplexer, a demodulator, or a demultiplexer, etc.).

The network device 102 and the network device 104 may communicate with one or more terminal devices similar to the terminal device 106. However, it should be understood that the terminal device communicating with the network device 102 and the terminal device communicating with the network device 104 may be the same or different. The terminal device 106 shown in FIG. 1 can communicate with the network device 102 and the network device 104 at the same time, but this only shows one possible scenario.

Hereinafter, without loss of generality, an interaction process between a terminal device and a network device is used as an example to describe the embodiments of the present application in detail. The terminal device may be a terminal device in a wireless communication system that has a wireless connection relationship with the network device. It is understandable that the network device may receive the power saving signal based on the same technical solution with multiple terminal devices in a wireless connection relationship in the wireless communication system, which is not limited in this application.

At present, in order to save the power consumption of the terminal device, the network device can send a PoSS signal to the terminal device to indicate whether the UE needs to wake up in the next one or more DRX cycles for PDCCH detection. As shown in Figure 2, the network device may send the GTS signal to the terminal device at the moment of receiving the go to sleep signal (GTS) at the start position of the DRX cycle. The terminal device needs to determine whether the network device has sent a GTS signal at the beginning of the DRX cycle. If the terminal device receives the GTS signal, the terminal device will sleep in the first DRX cycle. If the terminal device does not receive the GTS signal, the terminal device will wake up and detect the PDCCH in the first DRX cycle.

However, there is signal attenuation during the transmission of PoSS signals, and due to problems such as the mobility and rotation of the terminal equipment, it is easy to cause the missed detection of PoSS signals or the poor signal quality of PoSS signals that cannot be accurately demodulated, which will cause problems.

In addition, a combination of these schemes can also be used.

The network architecture and business scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. Those of ordinary skill in the art will know that with the network With the evolution of the architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

The embodiments of this application can be applied to both traditional typical networks and future UE-centric networks. The UE-centric network introduces a non-cell network architecture, that is, a large number of small stations are deployed in a specific area to form a hyper cell, and each small station is a transmission point of the Hyper cell ( Transmission Point, TP) or Transmission and Reception Point (TRP), and is connected to a centralized controller (controller). When the UE moves in the Hypercell, the network side device selects a new sub-cluster (sub-cluster) for the UE to serve it, thereby avoiding real cell switching and realizing UE service continuity. Among them, the network side device includes a wireless network device. Or, in a UE-centric network, multiple network-side devices, such as small stations, can have independent controllers, such as distributed controllers. Each small station can independently schedule users. The existence of interactive information allows flexibility when providing cooperative services for the UE.

Before the base station is deployed, the base station does not know whether it will involve the scenario applied in the embodiment of the present application. It is understandable that the aforementioned base stations with different identities may be base station identities, cell identities or other identities.

Some scenarios in the embodiments of this application are described by taking the scenario of the NR network in a wireless communication network as an example. It should be noted that the solutions in the embodiments of this application can also be applied to other wireless communication networks, and the corresponding names can also be other. Replace the name of the corresponding function in the wireless communication network.

Fig. 3 is an exemplary flow chart of the communication method provided by an embodiment of the present application from the perspective of device interaction. As shown in Figure 3, the method may include:

Step 301: The terminal device receives the PoSS signal sent by the network device.

The PoSS signal here is used to instruct the terminal device to sleep or wake up in the first DRX cycle. The PoSS signal can be a WUS signal or a GTS signal. When the PoSS signal is a WUS signal, the PoSS signal is used to instruct the terminal device to wake up in the first DRX cycle, and when the PoSS signal is a GTS signal, the PoSS signal is used to instruct the terminal device to sleep in the first DRX cycle.

When the terminal device receives the PoSS signal, it can use the diversity reception mode to receive the PoSS signal. For example, a terminal device based on the MIMO protocol may have x transmitting antennas and y receiving antennas. The diversity receiving mode may mean that the terminal device can use multiple receiving antennas among the y receiving antennas to receive the PoSS signal. For example, the terminal device can determine the receiving diversity parameter, and receive the PoSS signal according to the receiving diversity parameter. The receiving diversity parameter here may include the index of at least one receiving antenna and the signal delay on the corresponding antenna. Wherein, the receiving diversity parameter may be preset, or may be determined according to the second parameter. The method for determining the receiving diversity parameter according to the second parameter will be specifically introduced below.

1. The second parameter may include the moving speed of the terminal device.

Generally speaking, the greater the moving speed of the terminal device, the greater the probability of missed detection and false detection of PoSS signals. Therefore, a diversity reception method with a larger diversity order can be used to receive PoSS signals. Among them, the diversity order may refer to the number of receiving antennas. For example, if a terminal device uses two receiving antennas to receive PoSS signals, the diversity order is 2.

When the speed of the terminal device v≤v ₁ , the terminal device can use one receiving antenna to receive the PoSS signal. When v>v ₁ and less than v _n , the terminal device can use N antennas to receive signals to save power. Wherein, N is a positive integer, and N is less than or equal to y. In the embodiment of the present application, the relationship between N and the speed threshold can be preset. For example, the terminal device can use v ₁ , v ₂ , ..., v _n as preset speed thresholds and v ₁ <v ₂ ＜…<v _n . Here v _n is the maximum terminal device moving speed allowed in the DRX mode. For example, the terminal device can determine the diversity order according to the following speed threshold:

When v≤v ₁ , use a single antenna to receive POSS signals, when v ₁ ＜v≤v ₂ , the diversity order can be 2, and two antennas can be used to receive POSS signals, when v ₂ ＜v≤v ₃ , the diversity order can be If it is 3, you can use 3 antennas to receive POSS signals, and so on. Here, v ₁ , v ₂ ... v _n may be predetermined according to empirical values. Optionally, when the moving speed of the terminal device is greater than v _n , the terminal device may send the speed v to the network device, thereby requesting the network device that the terminal device exits the DRX mode.

2. The second parameter may include the distance of the terminal device relative to the serving base station.

Generally speaking, the greater the distance between the terminal equipment and the serving base station, the greater the probability of missed detection and false detection of PoSS signals. Therefore, a diversity reception method with a larger diversity order can be used to receive PoSS signals.

When the distance between the terminal device and the serving base station is D≤D1, one receiving antenna may be used to receive the PoSS signal. When D1<D≦Dn, the terminal device can use M antennas to receive signals to save power, where M is a positive integer, and M is less than or equal to y. In the embodiment of the present application, the relationship between M and the distance threshold can be preset. For example, the terminal device may use D1, D2,...Dn as the preset speed threshold and D1<D2<...<Dn. Here Dn is the maximum distance between the terminal device and the serving base station allowed by the DRX mode. For example, the terminal device can determine the diversity order according to the following distance threshold:

When D≤D1, a single antenna can be used to receive PoSS signals. When D1＜D≤D2, the diversity order can be 2, and two antennas can be used to receive PoSS signals. When D2＜D≤D3, the diversity order can be 3. Use three antennas to receive PoSS signals, and so on. D1, D2, ... Dn here can be predetermined based on empirical values. Optionally, when the distance between the terminal device and the serving base station is greater than Dn, the terminal device may send the distance D to the network device, thereby requesting the network device that the terminal device exits the DRX mode.

3. The second parameter may include the sleep time of the terminal device.

The sleep time here may be the accumulated sleep time of the terminal device for a specified period of time. The designated duration may be preset according to an empirical value, or the designated duration may also be the accumulated duration from the most recent sleep before the first DRX cycle to the current time. For example, if the terminal device sleeps in the second DRX cycle, the sleep time of the terminal device may be the accumulated sleep time from the sleep time of the terminal device in the second DRX cycle to the current time. The second DRX cycle here may be the previous DRX cycle of the first DRX cycle.

Generally speaking, the longer the sleep time of the terminal device, the greater the probability of missed detection and false detection of PoSS signals. Therefore, a diversity reception method with a larger diversity order can be used to receive PoSS signals.

When the sleep time of the terminal device T≤T1, one receiving antenna may be used to receive the PoSS signal. When T1<T≤Tn, the terminal device can use Z antennas to receive PoSS signals. Among them, Z is a positive integer, and Z is less than or equal to y. In the embodiment of the present application, the relationship between Z and the sleep time threshold can be preset. For example, the terminal device can use T1, T2,...Tn as the preset sleep time threshold and T1<T2<...<Tn. Here Tn is the maximum sleep time of the terminal device allowed by the DRX mode. For example, the terminal device can determine the diversity order according to the following sleep time threshold:

When T≤T1, a single antenna can be used to receive PoSS signals. When T1＜T≤T2, the diversity order can be 2, and two antennas can be used to receive PoSS signals. When T2＜T≤T3, the diversity order can be 3. Use 3 antennas to receive PoSS signals, and so on. Here, T1, T2,...Tn can be predetermined based on empirical values. When the sleep time of the terminal device is greater than Tn, the terminal device can exit the DRX mode or wake up.

For example, the terminal device has 4 receiving antennas, which are antenna 1, antenna 2, antenna 3, and antenna 4. The terminal device can determine the diversity order according to its own moving speed, the distance from the serving base station, and its own sleep time. For example, the terminal device determines that it can use 2 antennas to receive PoSS signals. The terminal device can determine the index of the receiving antenna and the signal delay on each receiving antenna according to the above-mentioned parameters. For example, the terminal device determines that it can use antenna 2 and antenna 3 to receive PoSS signals, and the signal delay of antenna 2 is a, and the signal delay of antenna 3 is b. The terminal device can receive the PoSS signal on the antenna 2 based on the signal delay a at the time when the PoSS signal is received, and receive the PoSS signal on the antenna 3 based on the signal delay b.

Through the above method, the terminal device can receive the PoSS signal according to the diversity receiving mode, and the robustness of the PoSS signal can be improved. The following describes the time when the terminal device receives the PoSS signal. Here, the time when the PoSS signal is received may also be referred to as the PoSS signal receiving time.

As shown in FIG. 4, the terminal device receives the PoSS signal at time t1, and the PoSS signal instructs the terminal device to sleep in the second DRX cycle, and the terminal device can sleep in the time period between t2-t3. The terminal device can end the sleep at time t3 and receive the PoSS signal before the arrival of the first DRX cycle. As shown in Fig. 4, the terminal device can receive the PoSS signal at time t4.

As shown in FIG. 5, the terminal device may also receive the PoSS signal at the beginning of the first DRX cycle. The time t1 in Fig. 5 is the start time of the first DRX cycle and is also the time when the PoSS signal is received. The terminal device can receive the PoSS signal at the time t1. If the PoSS signal is a WUS signal, the terminal device can wake up and detect the PDCCH in the first DRX cycle.

Step 302: The terminal device sleeps or wakes up in the first DRX cycle according to the signal quality of the received PoSS signal.

The signal quality here can be the reference signal received power (RSRP) of the PoSS signal, the reference signal received quality (RSRQ), the received signal strength indicator (RSSI) or the signal Noise to interference ratio (signal to interference plus noise ratio, SINR). Alternatively, the signal quality may also be multiple combinations of RSRP, RSRQ, RSSI, or SINR. For example, the weight of the reference quantity of each signal quality can be preset, and the reference quantities of each signal quality can be weighted and summed according to the weight, and the result of the weighted sum can be the signal quality.

The following describes the scheme for the terminal device to sleep or wake up in the first DRX cycle when the signal quality of the PoSS signal is different, which may include the following scheme 1 and scheme 2:

Solution 1: The signal quality of the PoSS signal is less than or equal to the first threshold.

The first threshold here may be predetermined according to an empirical value, which is not specifically limited in this application. Wherein, when the signal quality of the PoSS signal is greater than the first threshold, the PoSS signal can be accurately demodulated and obtained. When the signal quality of the PoSS signal is less than or equal to the first threshold, the PoSS signal cannot be accurately demodulated to obtain the PoSS signal. When the signal quality of the PoSS signal is less than or equal to the first threshold, the terminal device can perform the following operations:

Operation 1: The terminal device wakes up in the first DRX cycle.

Specifically, the terminal device may wake up in the first DRX cycle when the signal quality of the PoSS signal is less than or equal to the first threshold. For example, the terminal device may perform operations such as detecting the PDCCH in the first DRX cycle, and reporting the measurement report in the first DRX cycle.

Exemplarily, as shown in FIG. 6, the terminal device receives the PoSS signal at time t1, and determines that the signal quality of the PoSS signal is less than or equal to the first threshold. Then, the terminal device can detect the PDCCH in the first DRX cycle. As shown in Figure 6, the terminal device can detect the PDCCH in the time period between t2-t3.

Operation 2: If the terminal device wakes up in the second DRX cycle, the terminal device wakes up in the first DRX cycle. The second DRX cycle here may be the previous DRX cycle of the first DRX cycle.

Exemplarily, as shown in FIG. 7, the terminal device receives a PoSS signal at time t1, and the PoSS signal instructs the terminal device to wake up in the second DRX cycle. The terminal device receives the PoSS signal again at time t2, and the signal quality of the PoSS signal is less than the first threshold. Then, the terminal device can decide to wake up in the first DRX cycle according to the wake-up situation in the second DRX cycle. As shown in FIG. 7, the terminal device can perform the operation of detecting the PDCCH in the time period between t3-t4.

Operation 3: If the terminal device sleeps in the second DRX cycle, the terminal device sleeps in the first DRX cycle. The second DRX cycle here may be the previous DRX cycle of the first DRX cycle.

Exemplarily, as shown in FIG. 8, the terminal device receives a PoSS signal at time t1, and the PoSS signal instructs the terminal device to sleep in the second DRX cycle. As shown in Figure 8, the terminal device can sleep in the time period between t2-t3. The terminal device receives the PoSS signal again at time t4, and the signal quality of the PoSS signal is less than the first threshold. Then, the terminal device may decide to sleep in the first DRX cycle according to the situation of sleep in the second DRX cycle. As shown in Figure 8, the terminal device can sleep in the time period between t5-t6.

Solution 2: The signal quality of the PoSS signal is greater than the first threshold.

The terminal device can wake up or sleep in the first DRX cycle according to the instruction of the PoSS signal. For example, when the PoSS signal is a WUS signal, the terminal device can wake up in the first DRX cycle. When the PoSS signal is the GTS signal, the terminal device can sleep in the first DRX cycle.

Based on the above solution, when the signal quality of the received PoSS signal of the terminal device is poor and cannot be accurately demodulated, the terminal device can also wake up or sleep in the first DRX cycle according to the solution provided by this application, without the need to maintain wake-up reception. The PoSS signal can reduce the power consumption of the terminal equipment, and can also reduce the data scheduling delay caused by the inability to obtain the PoSS signal.

It is described above that after receiving the PoSS signal, the terminal device can determine whether to wake up or sleep in the first DRX cycle according to the signal quality of the PoSS signal. The following describes how the terminal device wakes up or sleeps when it does not receive a PoSS signal. FIG. 9 is a flowchart of another communication method provided by an embodiment of the present application from the perspective of device interaction, which may include the following steps:

Step 901: The network device sends a PoSS signal. The PoSS signal here may be a WUS signal or a GTS signal, and the PoSS signal is used to instruct the terminal device to wake up or sleep in the first DRX cycle.

In addition, it should be noted that the time when the network device sends the PoSS signal can be determined in advance, which can also be referred to as the PoSS signal sending time, and the network device can send the PoSS signal at the PoSS signal sending time. Then, the terminal device can receive the PoSS signal at the corresponding PoSS signal receiving moment. For example, a network device can send a PoSS signal at t4 in Figure 4, and a terminal device can receive a PoSS signal at t4 in Figure 4. Alternatively, the network device may send the PoSS signal at time t1 in FIG. 5, and the terminal device may receive the PoSS signal at time t1 in FIG. 5.

Step 902: If the terminal device receives the PoSS signal, it sleeps or wakes up in the first DRX cycle according to the instructions of the PoSS signal; if the terminal device does not receive the PoSS signal, it determines the terminal according to the preset receiving method when receiving the PoSS signal The device sleeps or wakes up in the first DRX cycle.

It should be understood that if the terminal device receives the PoSS signal, the terminal device can sleep or wake up in the first DRX cycle according to the indication of the PoSS signal. For example, if the PoSS signal is a WUS signal, the terminal device sleeps in the first DRX cycle, and if the PoSS signal is a GTS signal, the terminal device wakes up in the first cycle. Alternatively, the terminal device can sleep or wake up in the first DRX cycle according to the signal quality of the PoSS signal, and the terminal device can sleep or wake up in the first DRX cycle according to the signal quality of the PoSS signal. The relevant description can refer to the above-mentioned Figure 3 The description in the method embodiment will not be repeated here.

If the terminal device does not receive the PoSS signal, the terminal device can determine to sleep or wake up in the first DRX cycle according to the receiving mode when receiving the PoSS signal. It should be understood that if the terminal device does not receive the PoSS signal, it can mean that there is no signal transmission at the time of PoSS signal reception, or it can also mean that there is signal transmission at the time of PoSS signal reception, but the signal quality of the signal is lower than the second threshold. As a result, the terminal device cannot receive the PoSS signal sent by the network device. Wherein, the second threshold may be predetermined according to an empirical value, such as -9dB, etc., which is not specifically limited in this application.

The receiving mode here may be an omnidirectional beam receiving mode, or may also be a directional beam receiving mode. The following describes how to determine the sleep or wake-up of a terminal device according to different receiving methods.

Method 1: The receiving method is the omnidirectional beam receiving method:

At the time when the PoSS signal is received, the terminal device uses the omnidirectional beam receiving mode to receive the PoSS signal, but does not receive the PoSS signal. Then, the terminal device can add 1 to the recorded total number of times that the PoSS signal has not been received. Optionally, the terminal device may maintain a counter, and the counter may be used to record the number of times the terminal device has not received the PoSS signal. The counter can be started when the terminal device enters the DRX mode and receives a downlink signal in the DRX mode, and is cleared and stops counting when the terminal device exits the DRX mode. For example, the terminal device starts a counter after entering the DRX mode, and the initial value of the counter is 0. When the terminal device does not receive the PoSS signal at the time of receiving the PoSS signal, the counter is incremented by 1. When the terminal device exits the DRX mode, the counter will clear the recorded value to zero and stop counting.

If the total number of times processed by adding 1 is less than the first specified value, for example, the value recorded by the counter is less than the first specified value, and the displacement of the terminal device is less than or equal to the second specified value, then the terminal device is in the first DRX cycle or the first specified value. Sleep in the DRX cycle and n DRX cycles after the first DRX cycle. Among them, n is a natural number. The first designated value and the second designated value may be predetermined based on empirical values, which are not specifically limited in this application.

The displacement here is the displacement between the first position and the second position of the terminal device. The first position may be the position where the terminal device is when it receives the PoSS signal corresponding to the second DRX cycle. The PoSS signal corresponding to the second DRX cycle is a signal that instructs the terminal device to sleep or wake up in the second DRX cycle. For example, the first position shown in FIG. 8 may be the position of the terminal device at time t1. The second position may be the position where the terminal device is when it receives the PoSS signal corresponding to the first DRX cycle. The PoSS signal corresponding to the first DRX cycle is a signal that instructs the terminal device to sleep or wake up in the first DRX cycle. For example, as shown in Figure 8, the second location may be the location of the terminal device at time t4. It should be understood that the first position is the position of the terminal device at the time when the PoSS signal in the second DRX cycle is received. Regardless of whether the terminal device receives the PoSS signal or not, the position of the terminal device at the time when the PoSS signal in the second DRX cycle is received is the first position. One location. Similarly, the second position is the position of the terminal device at the time when the PoSS signal of the first DRX cycle is received. Regardless of whether the terminal device receives the PoSS signal or not, the position of the terminal device at the time of receiving the PoSS signal in the first DRX cycle is the first position. Two positions.

If the total number of times after adding 1 is greater than or equal to the first specified value, for example, the value recorded by the counter is greater than or equal to the first specified value, the terminal device wakes up in the first DRX cycle and sends the first parameter to the network device. The first parameter here is used to request the network device to exit the DRX mode. In other words, when the total number of times processed by adding 1 is greater than or equal to the first designation, the terminal device can exit the DRX mode and use other methods to receive downlink signals.

Method 2: The receiving method is a directional beam receiving method:

The terminal device uses the directional beam receiving mode to receive the PoSS signal at the time of PoSS signal reception, but when the PoSS signal is not received, the terminal device can add 1 to the recorded total number of times that the PoSS signal is not received. To facilitate recording, the terminal device can maintain a counter, which can be used to record the number of times the terminal device has not received a PoSS signal. In the embodiment of the present application, the counter can be started when the terminal device enters the DRX mode, and cleared and stopped when the terminal device exits the DRX mode. For example, the terminal device starts a counter after entering the DRX mode, and the initial value of the counter is 0. When the terminal device does not receive the PoSS signal at the time of receiving the PoSS signal, the counter is incremented by 1. When the terminal device exits the DRX mode, the counter will clear the recorded value to zero and stop counting.

If the total number of times after adding 1 processing (such as the value recorded by the counter) is less than the third specified value, the displacement of the terminal device is less than or equal to the fourth specified value, and the rotation angle of the terminal device is less than the fifth specified value, the terminal device can Sleep in the first DRX cycle or the first DRX cycle and m DRX cycles after the first DRX cycle. Among them, m is a positive integer. The third designated value, the fourth designated value, and the fifth designated value may be predetermined according to experience values, and this application does not make specific limitations. Wherein, the third specified value may be the same as the first specified value, and the fourth specified value may be the same as the second specified value.

The displacement here is the displacement between the first position and the second position of the terminal device, and the rotation angle may be the difference between the angle of the terminal device at the first position and the angle at the second position. The first position here may be the position where the terminal device is when it receives the PoSS signal corresponding to the second DRX cycle. The PoSS signal corresponding to the second DRX cycle is a signal that instructs the terminal device to sleep or wake up in the second DRX cycle. For example, as shown in FIG. 8, the first position may be the position of the terminal device at time t1. The second position may be the position where the terminal device is when it receives the PoSS signal corresponding to the first DRX cycle. The PoSS signal corresponding to the first DRX cycle is a signal that instructs the terminal device to sleep or wake up in the first DRX cycle. For example, as shown in Figure 8, the second location may be the location of the terminal device at time t4. It should be understood that the first position is the position of the terminal device at the time when the PoSS signal in the second DRX cycle is received. Regardless of whether the terminal device receives the PoSS signal or not, the position of the terminal device at the time when the PoSS signal in the second DRX cycle is received is the first position. Location. Similarly, the second position is the position of the terminal device at the time the PoSS signal of the first DRX cycle is received. Regardless of whether the terminal device receives the PoSS signal or not, the position of the terminal device at the time the PoSS signal of the first DRX cycle is received is the first position. Location or second location.

If the total number of times after adding 1 processing (such as the value recorded by the counter) is less than the third specified value, and the displacement of the terminal device is greater than the fourth specified value, the terminal device wakes up in the first DRX cycle. At this time, since the terminal device is moving and moving at a relatively high speed, it is necessary to wake up the terminal device to perform a wake-up detection PDCCH to prevent the missed detection of the PoSS signal.

If the total number of times after adding 1 processing (such as the value recorded by the counter) is greater than or equal to the third specified value, the terminal device needs to wake up in the first DRX cycle and send the first parameter to the network device. The first parameter here is used to request the network device to exit the DRX mode. In other words, when the total number of times processed by adding 1 is greater than or equal to the first designation, the terminal device can exit the DRX mode and use other methods to receive downlink signals.

Based on the foregoing solution, in the embodiment of the present application, when the PoSS signal is not received, it may be determined to sleep or wake up in the first DRX cycle according to the preset receiving manner of receiving the PoSS signal. In this way, the data scheduling time delay caused by the terminal device not receiving the PoSS signal can be reduced, and the waste of power consumption caused by the terminal device continuously detecting the PDCCH can also be reduced.

The following describes the communication method provided by the embodiments of the present application through specific embodiments. As shown in FIG. 10, an exemplary flow chart of the traffic method provided in this embodiment of the application may include the following steps:

Step 1001: The terminal device determines the reception diversity parameter according to the second parameter.

Wherein, the receive diversity parameter may include the index of at least one receive antenna and the corresponding signal delay. For related description, refer to the description in the foregoing method embodiment, and will not be repeated here.

Step 1002: The terminal device receives the PoSS signal at the time when the PoSS signal is received.

The PoSS signal reception time here can be seen in Fig. 4 and Fig. 5, and will not be repeated here in order to avoid repetition.

Step 1003: The terminal device judges the signal quality of the PoSS signal. If the signal quality of the PoSS signal is greater than the first threshold, go to step 1004; if the signal quality of the PoSS signal is greater than the second threshold and less than or equal to the first threshold, go to step 1005; if the signal quality of the PoSS signal is less than or equal to the second threshold Threshold, go to step 1006.

For related descriptions of the first threshold and the second threshold here, reference may be made to the description in the foregoing method embodiment, and details are not repeated here.

Step 1004: The terminal device sleeps or wakes up in the first DRX cycle according to the instruction of the PoSS signal.

If the PoSS signal here is a WUS signal, the terminal device wakes up in the first DRX cycle. If the PoSS signal here is a GTS signal, the terminal device sleeps in the first DRX cycle.

Step 1005: The terminal device wakes up in the first DRX cycle, or the terminal device remains in the state when the first DRX cycle is in the second DRX cycle.

The state when the terminal device remains in the second DRX cycle here means that if the terminal device sleeps in the second DRX cycle, the terminal also sleeps in the first DRX cycle. If the terminal device wakes up in the second DRX cycle, the terminal device also sleeps in the first DRX cycle.

Step 1006: The terminal device adds 1 to the recorded total number of times that the PoSS signal has not been received, and continues to perform step 1007.

In one embodiment, the terminal device may maintain a counter for recording the number of times that the PoSS signal is not received. Specifically, the relevant description of the counter can refer to the above-mentioned embodiment.

Step 1007: The terminal device judges whether the total number of times is greater than the first specified value, if yes, execute step 1008; if not, execute step 1009.

It should be understood that the first specified value here may be the first specified value in the foregoing method embodiment, or may be the third specified value in the foregoing method embodiment.

Step 1008: The terminal device wakes up in the first DRX cycle and sends the first parameter to the network device.

The first parameter here is a parameter used to request the network device to exit the DRX mode.

Step 1009: The terminal device determines to sleep or wake up in the first DRX cycle according to the receiving mode.

The receiving mode here may include an omnidirectional beam receiving mode and a directional beam receiving mode. For the specific implementation method, refer to the related description in the above method embodiment, and will not be repeated here in order to avoid repetition.
