Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a communication method and related devices. Background Art

[0002] The 3GPP project proposed a new feature, which is to design a set of low-power receivers separately to reduce the energy consumption of the user equipment (UE) during the blind detection of the physical downlink control channel (PDCCH). When the network side sends data to the UE, the network side first sends a low power wake-up signal (LP-WUS) to wake up the main receiver, and then the main receiver performs PDCCH blind detection and receives the corresponding data scheduling. Since the low-power receiver (also called auxiliary receiver or LP-WUR) usually uses a low-speed, low-precision analog-to-digital converter (ADC), a low-precision local oscillator, and a low-complexity digital processing module, the power consumption of the low-power receiver is much lower than that of the traditional main receiver. Therefore, by using the low-power receiver to receive the wake-up signal and then waking up the main receiver to receive data scheduling, the purpose of reducing the power consumption of the UE can be achieved. Figure 1 The relationship between the main receiver 102 and the low power receiver 101 is given, wherein when the low power receiver 101 is turned on, the main receiver 102 may enter a sleep state, thereby saving energy. When the low power receiver receives the LP-WUS, the UE wakes up the main receiver and performs subsequent operations such as data reception through the main receiver.

[0003] There are many methods to improve the LP-WUS monitoring performance, such as time / frequency domain repetition, energy concentrated transmission, transmission diversity, frequency modulation and other technologies, which need to be notified to the UE in advance. For example, the network side needs to inform the UE of the LP-WUS transmission method before the UE monitors the LP-WUS, such as the number of signal repetitions in time or whether to use frequency hopping technology. In terms of improving the LP-WUS monitoring performance, how to ensure that the PDCCH is accurately monitored is still a technical problem that needs to be solved by technicians in this field. Summary of the invention

[0004] The embodiments of the present application provide a communication method and related devices, which can avoid as much as possible the problem of missing the reception of first information (such as PDCCH) due to the delay in switching to the second working mode (such as the mode in which the main receiver receives the signal).

[0005] In a first aspect, an embodiment of the present application provides a communication method, the method comprising:

[0006] Sending low power consumption indication information to the terminal device in the DRX active state activated by the discontinuous monitoring mechanism, and starting a first timer to start timing, wherein the low power consumption indication information is used to instruct the terminal device to switch from the first working mode to the second working mode, and the power consumption of the terminal device in the second working mode is greater than the power consumption in the first working mode;

[0007] During the timing of the first timer, first information is sent to the terminal device, wherein the first information includes a physical downlink control channel PDCCH and / or a measurement signal, and the communication state during the timing of the first timer belongs to the DRX active state.

[0008] In this method, since the first timer timer1 is triggered, there is sufficient time within timer1 to receive the first information (such as PDCHH), which can avoid the problem of missing the first information reception due to the delay in switching to the second working mode.

[0009] In an optional implementation, the method further includes:

[0010] When the first information is transmitted, the first timer is stopped and the first timer is initialized.

[0011] It can be understood that when the first information is sent, stopping and initializing the first timer in a timely manner can free up time resources for receiving and sending other data, thereby improving communication efficiency and time resource utilization.

[0012] In an optional implementation, the first information is a signal of non-scheduled initial transmission data.

[0013] In yet another optional implementation, the low power consumption indication information includes first indication information, and the first indication information is used to indicate whether to trigger the first timer.

[0014] It can be understood that the first indication information is used to indicate whether to trigger the first timer in the low power consumption indication information. That is to say, the embodiment of the present application actually provides two methods of triggering the first timer and not triggering the first timer, which can adapt to more scenario requirements. For a specific scenario, one of the two methods is selected in a targeted manner, which can at least ensure receiving PDCCH and reducing monitoring power consumption.

[0015] In yet another optional implementation, the method further includes:

[0016] In the discontinuous monitoring mechanism, the DRX off state is deactivated and low power consumption indication information is sent to the terminal device, and a second timer is started to start timing;

[0017] During the timing of the second timer, a second signal is sent to the terminal device, wherein the second signal includes a physical downlink control channel PDCCH and / or a measurement signal.

[0018] In this implementation, low power indication information can also be sent in the DRX off state, thereby triggering the terminal device to subsequently switch from the first working mode to the second working mode, and then receive the second signal, thereby meeting the mode switching requirements of more scenarios. Furthermore, since the DRX off state triggers the timer, the terminal device can be triggered to send and receive data in the DRX off stage, reducing latency.

[0019] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up receiving signal LP-WUS.

[0020] In yet another optional implementation, the first information is PDCCH, and the first information is scrambled by a cell radio network temporary identifier C-RNTI.

[0021] In a second aspect, an embodiment of the present application provides a communication method, the method comprising:

[0022] receiving low power consumption indication information sent by a network device in a DRX active state activated by a discontinuous monitoring mechanism, and starting a first timer to start timing, wherein the low power consumption indication information is used to indicate switching from the first working mode to the second working mode;

[0023] In response to the low power consumption indication information, switching from the first working mode to the second working mode, wherein the power consumption in the second working mode is greater than the power consumption in the first working mode;

[0024] During the timing of the first timer, first information sent by the device is monitored, wherein the first information includes a physical downlink control channel PDCCH and / or a measurement signal, and the communication state during the timing of the first timer belongs to the DRX active state.

[0025] In this method, since the first timer timer1 is triggered, there is sufficient time within timer1 to receive the first information (such as PDCHH), which can avoid the problem of missing the first information reception due to the delay in switching to the second working mode.

[0026] In an optional implementation, the method further includes:

[0027] When the first information is monitored, the first timer is stopped and the first timer is initialized.

[0028] It can be understood that when the first information is received, stopping and initializing the first timer in a timely manner can free up time resources for receiving and sending other data, thereby improving communication efficiency and time resource utilization.

[0029] In yet another optional implementation, the first information is a signal of non-scheduled initial transmission data.

[0030] In yet another optional implementation, the low power consumption indication information includes first indication information, and the first indication information is used to indicate whether to trigger the first timer.

[0031] It can be understood that the first indication information is used to indicate whether to trigger the first timer in the low power consumption indication information. That is to say, the embodiment of the present application actually provides two methods of triggering the first timer and not triggering the first timer, which can adapt to more scenario requirements. For a specific scenario, one of the two methods is selected in a targeted manner, which can at least ensure receiving PDCCH and reducing monitoring power consumption.

[0032] In yet another optional implementation, the receiving low power consumption indication information sent by the network device in the DRX active state activated by the discontinuous monitoring mechanism and starting the first timer to start timing includes:

[0033] Receive low power indication information sent by network equipment in DRX active state activated by discontinuous monitoring mechanism;

[0034] If the first indication information in the low power consumption indication information indicates to trigger the first timer, the first timer is triggered to start timing.

[0035] In yet another optional implementation, the method further includes:

[0036] If the first indication information in the low power consumption indication information indicates not to trigger the first timer, monitoring the PDCCH in the DRX active state.

[0037] This method does not rely on the first timer mentioned above, but monitors PDCCH through other methods (such as traditional methods). This can avoid the problem of increased blind detection time of PDCCH by the terminal device due to triggering timer1 in some scenarios, thereby avoiding excessive power consumption of the terminal device.

[0038] In yet another optional implementation, the method further includes:

[0039] In the DRX off state where the discontinuous monitoring mechanism is deactivated, low power consumption indication information sent by the network device is received, and a second timer is started to start timing;

[0040] In response to the low power consumption indication information, switching from the first operating mode to the second operating mode;

[0041] During the timing of the second timer, a second signal sent by the network device is monitored, wherein the second signal includes a physical downlink control channel PDCCH and / or a measurement signal.

[0042] In this way, since the DRX off state triggers the timer, the terminal device can be triggered to send and receive data during the DRX off phase, thereby reducing latency.

[0043] In yet another optional implementation, the timing duration of the first timer is configured by the network device.

[0044] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up receiving signal LP-WUS.

[0046] In a third aspect, an embodiment of the present application provides a communication method, the method comprising:

[0047] If the remaining duration is less than the reference duration, the discontinuous monitoring mechanism after the first moment activates the DRX active state to send first information to the terminal device, wherein the first information includes a physical downlink control channel PDCCH and / or a measurement signal, and the remaining duration is the duration from the first moment to the moment when the DRX active state is judged to end at the first moment, and the first moment is the current moment;

[0048] If the remaining duration is greater than the reference duration, low power consumption indication information is sent to the terminal device after the first moment, wherein the low power consumption indication information is used to indicate switching from the first working mode to the second working mode, and the power consumption of the terminal device in the second working mode is greater than the power consumption in the first working mode.

[0049] In this method, by comparing the remaining duration with the reference duration, it is determined whether there is enough time to switch from the first working mode to the second working mode by responding to the low power consumption indication before the end of the DRXactive state. If it is too late, the low power consumption indication information is not sent to trigger the switching process. If it is in time, the low power consumption indication information is sent to trigger the switching process. In this way, invalid switching can be avoided as much as possible, reducing power consumption overhead and communication resource overhead.

[0050] In an optional implementation, the reference duration is a configured duration that represents the time from when the terminal device receives power consumption indication information to when the first working mode is switched to the second working mode.

[0055] If the remaining time is greater than the reference time, receiving low power consumption indication information sent by the network device after the first moment;

[0056] In response to the low power consumption indication information, the terminal device switches from the first working mode to the second working mode, and the power consumption of the terminal device in the second working mode is greater than the power consumption in the first working mode.

[0057] In the method, by comparing the remaining time with the reference time, it is determined whether it is in time to switch from the first working mode to the second working mode by responding to the low power consumption indication before the DRX active state ends. If it is too late, the low power consumption indication information is not sent to trigger the switching process. If it is in time, the low power consumption indication information is sent to trigger the switching process. In this way, invalid switching can be avoided as much as possible, and power consumption overhead and communication resource overhead are reduced.

[0146] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices or smart wearable devices, etc., which are a general term for the application of wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-size, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, etc., as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0147] The various terminal devices introduced above, if located on a vehicle (e.g., placed in a vehicle or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBU). In the embodiment of the present application, the terminal device may also include a relay. Alternatively, it can be understood that anything that can communicate data with a base station can be considered as a terminal device.

[0148] In the embodiment of the present application, the device for realizing the function of the terminal device may be a terminal device, or a device capable of supporting the terminal device to realize the function, such as a chip system, which may be installed in the terminal device. In the embodiment of the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices. In the technical solution provided in the embodiment of the present application, the technical solution provided in the embodiment of the present application is described by taking the terminal device as an example in which the device for realizing the function of the terminal is a terminal device.

[0149] 2) Network equipment, for example, including access network (AN) equipment, such as base stations (e.g., access points), which can refer to equipment in the access network that communicates with wireless terminal devices over the air interface through one or more cells, or, for example, a network device in a vehicle-to-everything (V2X) technology is a roadside unit (RSU). The base station can be used to convert received air frames to and from IP packets, acting as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network. The RSU can be a fixed infrastructure entity that supports V2X applications and can exchange messages with other entities that support V2X applications. The network equipment can also coordinate the attribute management of the air interface. For example, the network device may include a base transceiver station (BTS) in a global system for mobile communications (Global System for Mobile Communication, GSM) or a code division multiple access (Code Division Multiple Access, CDMA) network, a NB (NodeB) in a wideband code division multiple access (WCDMA), an evolutionary base station (NodeB or eNB or e-NodeB, evolutional NodeB) in a long-term evolution LTE system or an advanced long-term evolution (long term evolution-advanced, LTE-A), or may also include a next generation node B (next generation nodeB, gNB) in a 5GNR system (also referred to as an NR system) or may also include a wireless controller, a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (Cloud RAN) system. In addition, the network device may also be a wearable device, an in-vehicle device, a transmission and reception point (TRP), etc., which is not limited in the embodiments of the present application.

[0150] The network equipment may also include core network equipment, such as access and mobility management function (AMF), user plane function (UPF), session management function (SMF), etc.

[0151] In an embodiment of the present application, the device for implementing the function of the network device may be a network device, or may be a device that can support the network device to implement the function, such as a chip system, which may be installed in the network device.

[0152] The embodiment of the present application considers introducing a discontinuous reception (DRX) mechanism into the transceiver link of LP-WUS, such as Figure 4 As shown, the embodiment of the present application considers allowing the terminal device (such as UE) to monitor the PDCCH in the active state (active) of each DRX cycle. There is a timer timer in each DRX cycle. At least one timer among multiple timers represents the active state. The timer is generally divided into an onduration timer and an inactivity timer. Among them, the start time of the onduration timer is fixed and configured by the network side; the inactivity timer is used for the PDCCH for initial data transmission, which can trigger the inactivity timer timing.

[0153] When using a low-power receiver for LP-WUS monitoring, the terminal device can turn off some functions of the main receiver, and then the main receiver can enter a certain sleep state. When the network device requires the main receiver to turn on the corresponding function (such as monitoring PDCCH, referred to as PDC), the main receiver of the terminal device switches from the sleep state to the working mode, but this process will have a wake-up delay, such as Figure 5 Optionally, the network device and the terminal device may inform each other of the approximate wake-up delay.

[0154] The inventors of the present application have found in their research that when the DRX mechanism is introduced into the transceiver link of LP-WUS, the terminal device receives LP-WUS, which may or may not cause the DRX active duration to be extended. These two situations will have different effects on the processing of subsequent service functions (such as monitoring PDCCH), such as:

[0155] If the terminal device receives LP-WUS and does not extend DRX active: Due to the main receiver wake-up delay of the terminal device and network scheduling, the network device can only send PDCCH after sending LP-WUS for a period of time, such as Figure 6As shown, since DRX active is not extended, PDCCH appears outside DRX active, which may cause the terminal device to be unable to receive PDCCH.

[0156] If the terminal device receives LP-WUS to extend DRX active: the PDCCH of the initial data transmission may have been transmitted within the original DRX active. If the terminal device is within the additional extended delay (such as Figure 7 The PDCCH monitored during this process may not be the PDCCH used to schedule initial data transmission. Therefore, the monitoring of this process will reduce the energy saving gain of the terminal equipment.

[0157] Based on the above research findings, the present application provides a variety of methods to enable the terminal device to receive the PDCCH of the initial transmission data in DRXactive as much as possible and / or reduce the monitoring power consumption of the terminal device as much as possible. The corresponding methods are as follows.

[0158] See also Figure 8 , Figure 8 A communication method provided in an embodiment of the present application can be based on Figure 2 or Figure 3 The method is implemented based on the architecture shown in the figure, and can also be implemented based on other architectures. The method includes but is not limited to the following steps:

[0159] Step S801: The network device sends low power indication information to the terminal device in the DRX active state activated by the discontinuous monitoring mechanism, and starts the first timer to start timing.

[0160] Specifically, the low power consumption indication information is used to instruct the terminal device to switch from the first working mode to the second working mode, and the power consumption of the terminal device in the second working mode is greater than the power consumption in the first working mode; for example, the low power consumption indication information can be LP-WUS.

[0161] In an embodiment of the present application, a first timer timer1 is added. When the low power consumption indication information is sent, the first timer is started (or triggered) to start timing. The timing duration of the first timer can be pre-configured. When the timing reaches the timing duration, it will be automatically closed, or it can be closed in advance when the corresponding conditions are met. Optionally, the configuration of the first timer timer1 can be carried and indicated by the radio resource control (Radio Resource Control, RRC) parameter DRXoff_durationtimer1.

[0162] In the embodiment of the present application, the network device specifically sends low power consumption indication information in the DRX active state and starts the first timer.

[0163] Step S802: During the timing of the first timer, the network device sends the first information to the terminal device.

[0164] In an embodiment of the present application, it can be pre-configured when configuring the timing duration of the first timer so that the communication state during the timing of the first timer belongs to the DRX active state, and the first information includes a physical downlink control channel PDCCH, a measurement signal or other information. Optionally, the first information may also include multiple items of PDCCH, measurement signal, and other signals, such as two items.

[0165] like Fig. 9 As shown, sending the first information needs to be during the timing of the first timer.

[0166] Step S803: The network device stops the first timer after sending the first information.

[0167] like Fig.10 As shown, if the first information is sent before the first timer expires, the first timer can be stopped in advance. In the embodiment of the present application, the first timer can be initialized after being stopped.

[0168] Step S804: the terminal device receives the low power indication information sent by the network device in the DRX active state activated by the discontinuous monitoring mechanism, and starts the first timer to start timing.

[0169] Among them, when the terminal device receives the low power consumption indication information shown, it starts the first timer to start timing. In the embodiment of the present application, the first timer of the network device and the first timer of the terminal device are synchronized. This can be configured in advance through the protocol, or the network device can send indication information to the terminal device for configuration or indication, which is not limited here.

[0170] Step S805: The terminal device responds to the low power consumption indication information and switches from the first working mode to the second working mode.

[0171] That is, the terminal device switches from the first working mode to the second working mode according to the indication of the low power indication information. Optionally, the first working mode in the embodiment of the present application can be a mode in which a low power receiver (also called an auxiliary receiver, LP-WUR) receives signals, and the second working mode can be a mode in which a main receiver receives signals.

[0172] Step S806: During the timing of the first timer, the terminal device monitors the first information sent by the network device.

[0173] Specifically, when the terminal device enters the second working mode, it can be used to monitor the first information, where the first information includes a physical downlink control channel PDCCH, a measurement signal or other information. Optionally, the first information may also include multiple items of PDCCH, measurement signal, and other signals, such as two items. In an embodiment of the present application, the timing for monitoring the first information is during the timing of the first timer. If the first information is not monitored during the timing of the first timer, the monitoring is terminated to avoid unnecessary power consumption overhead, such as Fig.11 shown.

[0174] Optionally, the first information belongs to a signal of non-scheduled initial transmission data, such as a PDCCH of non-scheduled initial transmission data.

[0175] Optionally, if the first information is PDCCH, then in one solution, the PDCCH is a signal scrambled by a cell-radio network temporary identifier (C-RNTI), and in another solution, the PDCCH is a signal scrambled by a non-C-RNTI.

[0176] Step S807: The terminal device stops the first timer when monitoring the first information.

[0177] In the embodiment of the present application, the first timer can be initialized after stopping the first timer.

[0178] In an optional implementation, the low power consumption indication information includes first indication information, and the first indication information is used to indicate whether to trigger the first timer. For example, the first indication information can be carried by 1 bit of information. When the value of the bit is 1, it indicates triggering (or starting) timer1, and when the value of the bit is 0, it indicates not triggering timer1.

[0179] In this optional implementation, there are two execution scenarios, as follows:

[0180] In case 1, the low power indication information sent by the network device is received in the DRX active state when the discontinuous monitoring mechanism is activated; if the first indication information in the low power indication information indicates that the first timer is triggered, the first timer is triggered to start timing. That is to say, there is a prerequisite for triggering the first timer to start timing in step S804, that is, the first indication information in the low power indication information indicates that the first timer is triggered, such as the value of the corresponding bit in the first indication information is 1.

[0181] In case 1, since the first timer timer1 is triggered, there is sufficient time within timer1 to receive the first information (such as PDCHH), which can avoid the problem of missing the first information reception due to the delay in switching to the second working mode.

[0182] Case 2: In the discontinuous monitoring mechanism, the DRX active state is activated to receive the low power indication information sent by the network device; if the first indication information in the low power indication information indicates that the first timer should not be triggered, then the operation of triggering the first timer in step S804 is not performed. In this case, normal operations can be performed, such as monitoring PDCCH in the DRXactive state. In this case, there is no need to rely on the first timer to control the timing of monitoring PDCCH.

[0183] For the second case, it can avoid the problem that in some scenarios, the terminal device's blind detection of PDCCH increases due to triggering timer1. Fig.12 In the scenario shown, when the terminal device wakes up the main receiver (corresponding to the second working mode) by sending LP-WUS to receive PDCCH (corresponding to the first information), the PDCCH is a PDCCH that is not scheduled for initial transmission of data. The terminal device should stop monitoring PDCCH at time 1 and enter the DRX off state. However, if timer1 is triggered, the actual monitoring time of PDCCH by the terminal device will continue until time 2, which increases the power consumption of the terminal device. Fig.12 In the scenario shown, timer1 may not be triggered, thereby preventing the terminal device from generating excessive power consumption.

[0184] In another optional implementation, low power indication information (such as LP-WUS) can trigger a timer in both the DRX off state and the DRX active state, and the terminal device continuously monitors the first information (such as PDCCH) during the timer timing. In the embodiment of the present application, the timer triggered in the DRX active state is the above-mentioned first timer timer1, and the timer triggered in the DRX off state can be called the second timer time2. In the embodiment of the present application, the reasons and effects of introducing the first timer timer1 have been introduced above. The introduction of the second timer timer2 can wake up the terminal device to monitor the first information (such as PDCCH) during the DRX off period, which is similar to the principle of the onduration timer. The relevant execution steps after the introduction of the second timer timer2 can be as follows:

[0185] Step S811: The network device sends low power indication information to the terminal device when the discontinuous monitoring mechanism deactivates the DRX off state, and starts the second timer to start timing; optionally, the timing duration configured for the second timer timer2 is longer than the timing duration configured for the first timer timer1. The timing duration in the embodiment of the present application refers to the maximum timing length. Both the first timer and the second timer may stop (or end) timing in advance under the triggering of corresponding conditions. Optionally, the configuration of the second timer timer2 can be carried and indicated by the Radio Resource Control (RRC) parameter DRXoff_durationtimer2. Optionally, DRXoff_durationtimer2 and the above-mentioned DRXoff_durationtimer1 are two different parameters; optionally, the value of DRXoff_durationtimer2 can be the same as the value of ondurationtimer in the existing RRC parameters.

[0186] Step S812: During the timing of the second timer, the network device sends a second signal to the terminal device, wherein the second signal includes a physical downlink control channel PDCCH and / or a measurement signal.

[0187] Step S813: The network device stops the second timer when sending the second signal.

[0188] Step S814: The terminal device receives the low power consumption indication information sent by the network device in the DRX off state when the discontinuous monitoring mechanism is deactivated, and starts the second timer to start timing.

[0189] Step S815: The terminal device responds to the low power consumption indication information and switches from the first operating mode to the second operating mode.

[0190] Step S816: During the timing of the second timer, the terminal device monitors the second signal sent by the network device, wherein the second signal includes a physical downlink control channel PDCCH and / or a measurement signal.

[0191] Step S817: The terminal device stops the second timer when detecting the second signal.

[0192] It should be noted that the implementation of steps S811-S817 can refer to the relevant implementation principles of steps S801-S807, and the main difference between the two is:

[0193] 1. The network device sends low power consumption indication information in the DRX off state, and the terminal device also receives low power consumption indication information in the DRX off state.

[0194] 2. The timing duration of the second timer is configured to be longer than the timing duration of the first timer.

[0195] exist Figure 8 In the described method, since the first timer timer1 is triggered, there is sufficient time to receive the first information (such as PDCHH) within timer1, so that the problem of missing the reception of the first information due to the delay in switching to the second working mode can be avoided as much as possible. In addition, by carrying the first indication information in the low-power indication information to indicate whether to start the first timer timer, a solution for not starting the first timer timer is provided, avoiding the problem of increasing the time of blind detection of PDCCH by the terminal device due to triggering timer1 in some scenarios. Furthermore, a solution for triggering the timer in the DRXoff state is also provided, which can trigger the terminal device to send and receive data in the DRX off stage to reduce the delay.

[0196] See also Fig.13 , Fig.13 A communication method provided in an embodiment of the present application can be based on Figure 2 or Figure 3 The method is implemented based on the architecture shown in the figure, and can also be implemented based on other architectures. The method includes but is not limited to the following steps:

[0197] Step S1301: If the remaining duration is less than the reference duration, the network device activates the DRX active state in a discontinuous monitoring mechanism after the first moment to send the first information to the terminal device.

[0198] Specifically, the network device can compare the remaining duration with the reference duration to determine which one is larger. Of course, other devices may also make the comparison and inform the network device of the result. The remaining duration is the duration from the first moment to the moment when the DRX active state is judged to end at the first moment. The first moment is the current moment. Optionally, the reference duration is the duration of the terminal device from receiving the power consumption indication information to switching the first working mode to the second working mode, which can be an estimated duration, such as an estimate based on experience and historical data. The reference duration can be configured by the network side or pre-defined by the protocol. It is used for reference comparison.

[0199] It should be noted that if the remaining duration is less than the reference duration, it is highly likely that the first operating mode cannot be switched to the second operating mode by responding to the low power indication information at the end of the DRX active state. Therefore, the low power indication information is not sent to trigger the switching process, but the first information is directly sent, wherein the first information includes a physical downlink control channel PDCCH, a measurement signal or other signals. Optionally, the first information may also include multiple items of PDCCH, measurement signal, and other signals, such as two items.

[0200] Among them, step S1301 can occur when the network device is in the period of sending low power consumption indication information. The period of sending low power consumption indication information refers to when the relevant conditions for sending low power consumption indication information to trigger the terminal device to switch from the first working mode to the second working mode are met. The relevant conditions can be pre-configured. When the relevant conditions are met, the network device has the ability to send low power consumption indication information. In an embodiment of the present application, when the network device meets the ability to send low power consumption indication information, it does not directly send the low power consumption indication information, but further determines the relationship between the remaining time and the reference time, and determines whether to send the low power consumption indication information based on the relationship.

[0201] Step S1302: If the remaining duration is less than the reference duration, the terminal device activates the DRX active state through the discontinuous monitoring mechanism after the first moment to receive the first information sent by the network device.

[0202] Similarly, on the terminal device side, the relationship between the remaining time and the reference time will also be determined. It can be obtained by comparing it itself, or other devices can compare and inform the terminal device of the result. If the remaining time is less than the reference time, the first information sent by the network device is received in the DRX active state after the first moment, instead of the low power consumption indication information, so it is too late to complete the switching process by responding to the low power consumption indication information.

[0203] Among them, step S1302 can occur when the terminal device is in the period of receiving low power consumption indication information. The period of receiving low power consumption indication information refers to when the relevant conditions for receiving low power consumption indication information and switching from the first working mode to the second working mode are met. The relevant conditions can be pre-configured. When the relevant conditions are met, the terminal device has the ability to receive low power consumption indication information. In an embodiment of the present application, when the terminal device meets the ability to receive low power consumption indication information, it does not directly receive (or monitor) the low power consumption indication information, but further determines the relationship between the remaining duration and the reference duration, and determines whether to receive the low power consumption indication information based on the relationship.

[0204] Step S1303: If the remaining duration is greater than the reference duration, the network device sends low power consumption indication information to the terminal device after the first moment.

[0205] Specifically, the low power consumption indication information is used to indicate switching from a first working mode to a second working mode, and the power consumption of the terminal device in the second working mode is greater than the power consumption in the first working mode; for example, the low power consumption indication information may be LP-WUS.

[0206] Optionally, the first working mode in the embodiment of the present application may be a mode in which a low power consumption receiver (also called an auxiliary receiver, LP-WUR) receives signals, and the second working mode may be a mode in which a main receiver receives signals.

[0207] Step S1304: If the remaining time is greater than the reference time, the terminal device receives the low power consumption indication information sent by the network device after the first moment.

[0208] Step S1305: The terminal device responds to the low power consumption indication information and switches from the first working mode to the second working mode.

[0209] That is, the terminal device switches modes according to the instructions of the low power indication information, for example, switching from a mode in which a low power receiver (also called an auxiliary receiver, LP-WUR) receives signals to a mode in which a main receiver receives signals.

[0210] Step S1306: The terminal device receives the first information in the second working mode.

[0211] For example, a PDCCH or a measurement signal is received in the second working mode. Optionally, the first information may also include multiple items, such as two items, of the PDCCH, the measurement signal, and other signals.

[0212] exist Fig.13 In the described method, by comparing the remaining time with the reference time, it is determined whether it is in time to switch from the first working mode to the second working mode by responding to the low power consumption indication before the end of the DRX active state. If it is not in time, the low power consumption indication information is not sent to trigger the switching process. If it is in time, the low power consumption indication information is sent to trigger the switching process. In this way, invalid switching can be avoided as much as possible, and power consumption overhead and communication resource overhead are reduced.

[0213] See also Fig.14 , Fig.14 A communication method provided in an embodiment of the present application can be based on Figure 2 or Figure 3 The method is implemented based on the architecture shown in the figure, and can also be implemented based on other architectures. The method includes but is not limited to the following steps:

[0214] Step S1401: The network device generates a first configuration parameter.

[0215] Wherein, the first configuration parameter includes a first duration, such as Fig.15 As shown, the first duration is used to indicate the time distance between the moment t2 when the terminal device switches from the first working mode to the second working mode and the end moment t1 of the last low power consumption indication information in a group of low power consumption indication information, which can also be understood as a wake-up delay for switching to the second working mode, which can be expressed as offset2. Optionally, the first duration can be an approximate value configured based on experience, and can be set to be greater than the lowest wake-up delay in history. The first duration is mainly used for reference and comparison.

[0216] The group of low power consumption indication information refers to the general term for multiple low power consumption indication information that needs to be repeatedly sent under certain conditions or in a specific stage. Optionally, the signals carried by the group of low power consumption indication information are the same.

[0217] Optionally, the low power consumption indication information includes a low power consumption wake-up receiving signal LP-WUS.

[0218] In addition, the reception of the low power consumption indication information also requires a process, so there is a difference between the end time and the reception time of the low power consumption indication information.

[0219] In an embodiment of the present application, the power consumption of the terminal device in the second working mode is greater than the power consumption in the first working mode. Optionally, the first working mode may be a mode in which a low power receiver (also called an auxiliary receiver, LP-WUR) receives signals, and the second working mode may be a mode in which a main receiver receives signals.

[0220] Step S1402: The network device sends the first configuration parameter to the terminal device.

[0221] Optionally, the first configuration parameter may be carried in downlink control information (Downlink Control Information, DCI), or in a MAC control element (Control Element, CE), or in a radio resource control (Radio Resource Control, RRC).

[0222] Step S1403: The network device sends first information to the terminal device.

[0223] Specifically, the first information may be a PDCCH, a measurement signal, or other signals. Optionally, the first information may also include multiple items, such as two items, of the PDCCH, the measurement signal, and other signals.

[0224] The execution order of step S1403 and steps S1402 and S1404 is not limited here.

[0225] Step S1404: The terminal device receives the first configuration parameter sent by the network device.

[0226] Step S1405: The terminal device determines a target time for switching from the first working mode to the second working mode according to the first configuration parameters.

[0227] Specifically, the terminal device determines the target time for switching from the first working mode to the second working mode according to the first duration in the first configuration parameter and other information. The other information may be information already in the terminal device or information sent by the network device to the terminal device. For ease of understanding, an example is given below:

[0228] In case 1, the first configuration parameter further includes a second time, a first quantity value, a second duration, and a third duration, wherein:

[0229] The second time is used to indicate the start time of monitoring the first low power consumption indication information in the group of low power consumption indication information. The first low power consumption indication information mentioned here refers to the low power consumption indication with the earliest sending time.

[0230] The first quantity value is used to indicate the number of low power consumption indication information in the set of low power consumption indication information, and can also be understood as the number of repetitions of the low power consumption indication information, such as the number of repetitions of LP-WUS, which is generally greater than 1.

[0231] The second duration is used to indicate the time occupied by the transmission of a single low-power indication information in the group of low-power indication information. It can be understood that the transmission of low-power indication information requires a certain amount of time. Optionally, in an embodiment of the present application, the time required for the transmission of each low-power indication information in the group of low-power indication information (or the time resources occupied) is the same.

[0232] The third duration is used to indicate the time distance between adjacent low power indication information in the set of low power indication information. For example, the set of low power indication information includes adjacent low power indication information 1 and low power indication information 2, and the transmission time of low power indication information 1 is before low power indication information 2, then the time distance between the monitoring end time of low power indication information 1 and the monitoring start time of low power indication information is the third duration here. Optionally, the third durations corresponding to any two sets of adjacent low power indication information are the same.

[0233] In this case, the terminal device specifically determines the target time according to the first duration, the second time, the first quantity value, the second duration and the third duration, for example. Fig.16 As shown, the target time t2 satisfies the following relationship:

[0234] t2=first_time_of_Wus+(Number_of_repetition-1)*offset1+Number_of_repetition*time_length+offset2;

[0235] Among them, first_time_of_Wus is the second moment, Number_of_repetition is the first number value, offset1 is the third duration, time_length is the second duration, and offset2 is the first duration.

[0236] Case 2, the first configuration parameter also includes a time list and a second duration, wherein:

[0237] The time list includes the monitoring start time of each low power indication information in the group of low power indication information. It can be understood that each low power indication information has a monitoring start time. Here, the monitoring start time of each low power indication information is reflected in the form of a time list and carried in the first configuration parameter, so as to be transmitted to the terminal device.

[0238] The second duration is used to indicate the time occupied by the transmission of a single low power consumption indication information in the group of low power consumption indication information. The supplementary explanation about the second duration has been described above and will not be repeated here.

[0239] In this case, the terminal device specifically determines the target time according to the first duration, the time list and the second duration, for example, Fig.17 As shown, the target time t2 satisfies the following relationship:

[0240] t2=first_time_of_Wus_list_last+time_length+offset2;

[0241] Among them, first_time_of_Wus_list_last is the monitoring start time that is last in the time list, time_length is the second time length, and offset2 is the first time length.

[0242] Case 3, the first configuration parameter also includes another time list, the other time list includes the monitoring end time of each low power consumption indication information in the set of low power consumption indication information. In this case, the above start time t2 satisfies the following relationship:

[0243] t2=first_time_of_Wus_list_end+offset2;

[0244] Among them, first_time_of_Wus_list_end is the monitoring end time that is the last in the time list, and offset2 is the first duration.

[0245] It is understandable that there are many other similar implementations, which will not be listed one by one here.

[0246] Step S1406: The terminal device switches from the first working mode to the second working mode at the target time.

[0247] For example, the mode of receiving signals through a low-power receiver (also called an auxiliary receiver, LP-WUR) is switched to a mode of receiving signals through a main receiver. Optionally, the corresponding specific operation may be to turn on the main receiver. Optionally, the low-power receiver may be turned off while the main receiver is turned on.

[0248] Step S1407: The terminal device receives the first information in the second working mode.

[0249] It should be noted that the relevant explanation about the first information can be referred to the previous description and will not be repeated here.

[0250] exist Fig.14 In the described method, the last low power indication information in a group of low power indication information is clearly taken as a benchmark, and a specific time is offset backward as the switching timing from the first working mode to the second working mode, thereby avoiding the problem of confusing or inappropriate or repeated switching timing when there are multiple low power indication information, and improving the switching efficiency and certainty.

[0251] The following is an introduction to the communication device provided in the embodiments of the present application.

[0252] The present application divides the functional modules of the communication device according to the above method embodiment. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or software functional modules. It should be noted that the division of modules in the present application is schematic and is only a logical function division. There may be other division methods in actual implementation. Figures 18 to 20 The communication device according to the embodiment of the present application is described in detail.

[0253] Fig.18 is a schematic diagram of the structure of a communication device provided in an embodiment of the present application, such as Fig.18 As shown, the communication device includes a processing module 1801 and a transceiver module 1802. The transceiver module 1802 can implement corresponding communication functions, and the processing module 1801 is used for data processing. For example, the transceiver module 1802 can also be called an interface, a communication interface or a communication module.

[0254] In some embodiments of the present application, the communication device can be used to execute the actions performed by the sender in the above method embodiment, such as the sender can be the device itself or a chip or functional module that can be configured in the device, etc. The transceiver module 1802 is used to perform the operations related to the sending and receiving of the sender in the above method embodiment, and the processing module 1801 is used to perform the operations related to the processing of the sender in the above method embodiment. The processing module 1801 can perform the corresponding operations by calling a computer program, or by a corresponding hardware circuit. The transceiver module 1802 can perform the transceiver operation independently, or it can perform the corresponding transceiver operation under the control of the processing module 1801.

[0255] For example, Fig.18 The communication device shown may be a network device or a device in a network device. The processing module 1801 and the transceiver module 1802 in the communication device may respectively perform the following operations:

[0256] The transceiver module 1802 is used to send low power consumption indication information to the terminal device when the DRX active state is activated by the discontinuous monitoring mechanism, and the processing module 1801 is used to start a first timer to start timing, wherein the low power consumption indication information is used to instruct the terminal device to switch from the first working mode to the second working mode, and the power consumption of the terminal device in the second working mode is greater than the power consumption in the first working mode;

[0257] The transceiver module 1802 is used to send first information to the terminal device during the timing of the first timer, wherein the first information includes a physical downlink control channel PDCCH or a measurement signal, and the communication state during the timing of the first timer belongs to the DRX active state.

[0258] In this method, since the first timer timer1 is triggered, there is sufficient time within timer1 to receive the first information (such as PDCHH), which can avoid the problem of missing the first information reception due to the delay in switching to the second working mode.

[0259] In one possible implementation:

[0260] The processing module 1801 is further configured to stop the first timer and initialize the first timer when the first information is sent.

[0261] It can be understood that when the first information is sent, stopping and initializing the first timer in a timely manner can free up time resources for receiving and sending other data, thereby improving communication efficiency and time resource utilization.

[0262] In yet another optional implementation, the first information is a signal of non-scheduled initial transmission data.

[0263] In yet another optional implementation, the low power consumption indication information includes first indication information, and the first indication information is used to indicate whether to trigger the first timer.

[0264] It can be understood that the first indication information is used to indicate whether to trigger the first timer in the low power consumption indication information. That is to say, the embodiment of the present application actually provides two methods of triggering the first timer and not triggering the first timer, which can adapt to more scenario requirements. For a specific scenario, one of the two methods is selected in a targeted manner, which can at least ensure receiving PDCCH and reducing monitoring power consumption.

[0265] In yet another optional implementation:

[0266] The transceiver module 1802 is further configured to send low power consumption indication information to the terminal device when the discontinuous monitoring mechanism deactivates the DRX off state, and the processing module 1801 is further configured to start the second timer to start timing;

[0267] The transceiver module 1802 is further used to send a second signal to the terminal device during the timing of the second timer, wherein the second signal includes a physical downlink control channel PDCCH and / or a measurement signal.

[0268] In this implementation, low power indication information can also be sent in the DRX off state, thereby triggering the terminal device to subsequently switch from the first working mode to the second working mode, and then receive the second signal, thereby meeting the mode switching requirements of more scenarios. In this way, since the DRX off state triggers the timer, the terminal device can be triggered to send and receive data in the DRX off stage, reducing latency.

[0269] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up receiving signal LP-WUS.

[0270] In yet another optional implementation, the first information is PDCCH, and the first information is scrambled by a cell radio network temporary identifier C-RNTI.

[0271] Reuse Fig.18 , in some other embodiments of the present application, exemplarily, Fig.18 The communication device shown may be a network device or a device in a network device. The processing module 1801 and the transceiver module 1802 in the communication device may respectively perform the following operations:

[0272] The transceiver module 1802 is configured to activate the DRX active state in a discontinuous monitoring mechanism after a first moment to send first information to the terminal device if the remaining duration is less than a reference duration, wherein the first information includes a physical downlink control channel PDCCH or a measurement signal, and the remaining duration is a duration from a first moment to a moment when the DRX active state is judged to end at the first moment, and the first moment is a current moment;

[0273] The transceiver module 1802 is used to send low power consumption indication information to the terminal device after the first moment if the remaining duration is greater than the reference duration, wherein the low power consumption indication information is used to indicate switching from the first working mode to the second working mode, and the power consumption of the terminal device in the second working mode is greater than the power consumption in the first working mode.

[0274] In this method, by comparing the remaining duration with the reference duration, it is determined whether there is enough time to switch from the first working mode to the second working mode by responding to the low power consumption indication before the end of the DRXactive state. If it is too late, the low power consumption indication information is not sent to trigger the switching process. If it is in time, the low power consumption indication information is sent to trigger the switching process. In this way, invalid switching can be avoided as much as possible, reducing power consumption overhead and communication resource overhead.

[0275] In an optional implementation, the reference duration is a configured duration that represents the time from when the terminal device receives power consumption indication information to when the first working mode is switched to the second working mode.

[0276] In yet another optional implementation, the method is applied to a network device, and the network device is in a period of sending the low power consumption indication information.

[0279] The processing module 1801 is used to generate a first configuration parameter, wherein the first configuration parameter includes a first duration, and the first duration is used to indicate the time distance between the moment when the terminal device switches from the first working mode to the second working mode and the end moment of the last low power consumption indication information in a set of low power consumption indication information, and the power consumption of the terminal device in the second working mode is greater than the power consumption in the first working mode;

[0280] The transceiver module 1802 is used to send the first configuration parameter to the terminal device.

[0281] In this method, the last low power indication information in a group of low power indication information is clearly taken as a benchmark, and a specific time is offset backward as the switching timing from the first working mode to the second working mode, thereby avoiding the problem of confusing, inappropriate or repeated switching timing when there are multiple low power indication information, and improving the switching efficiency and certainty.

[0282] In an optional implementation:

[0283] The transceiver module 1802 is used to send first information to the terminal device, wherein the first information includes a physical downlink control channel PDCCH and / or a measurement signal.

[0284] In another optional implementation, the first configuration parameter also includes a second moment, a first quantity value, a second duration and a third duration, wherein the second moment is used to indicate the starting moment of monitoring the first low power consumption indication information in the group of low power consumption indication information, the first quantity value is used to indicate the number of low power consumption indication information in the group of low power consumption indication information, the second duration is used to indicate the time occupied by the transmission of a single low power consumption indication information in the group of low power consumption indication information, and the third duration is used to indicate the time distance between adjacent low power consumption indication information in the group of low power consumption indication information.

[0285] In another optional implementation, the first configuration parameter also includes a time list and a second duration, the time list including the starting time of each low power consumption indication information in the set of low power consumption indication information, and the second duration is used to indicate the time occupied by the transmission of a single low power consumption indication information in the set of low power consumption indication information.

[0286] In yet another optional implementation, the signals carried by the set of low power consumption indication information are the same.

[0287] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up receiving signal LP-WUS.

[0288] Reuse Fig.18 , in some other embodiments of the present application, exemplarily, Fig.18 The communication device shown may be a terminal device or a device in a terminal device. The processing module 1801 and the transceiver module 1802 in the communication device may respectively perform the following operations:

[0289] The transceiver module 1802 is used to receive low power consumption indication information sent by the network device in the DRX active state activated by the discontinuous monitoring mechanism, and the processing module 1801 is used to start the first timer to start timing, wherein the low power consumption indication information is used to indicate switching from the first working mode to the second working mode;

[0290] The processing module 1801 is configured to switch from the first working mode to the second working mode in response to the low power consumption indication information, wherein the power consumption in the second working mode is greater than the power consumption in the first working mode;

[0291] The transceiver module 1802 is used to monitor the first information sent by the device during the timing of the first timer, wherein the first information includes a physical downlink control channel PDCCH and / or a measurement signal, and the communication state during the timing of the first timer belongs to the DRX active state.

[0292] In this method, since the first timer timer1 is triggered, there is sufficient time to receive the first information (such as PDCHH) within timer1, which can avoid the problem of missing the first information reception due to the delay in switching to the second working mode.

[0293] In an optional implementation:

[0294] The processing module 1801 is used to stop the first timer and initialize the first timer when the first information is monitored.

[0295] It can be understood that when the first information is received, stopping and initializing the first timer in a timely manner can free up time resources for receiving and sending other data, thereby improving communication efficiency and time resource utilization.

[0296] In yet another optional implementation, the first information is a signal of non-scheduled initial transmission data.

[0297] In yet another optional implementation, the low power consumption indication information includes first indication information, and the first indication information is used to indicate whether to trigger the first timer.

[0298] It can be understood that the first indication information is used to indicate whether to trigger the first timer in the low power consumption indication information. That is to say, the embodiment of the present application actually provides two methods of triggering the first timer and not triggering the first timer, which can adapt to more scenario requirements. For a specific scenario, one of the two methods is selected in a targeted manner, which can at least ensure receiving PDCCH and reducing monitoring power consumption.

[0299] In yet another optional implementation, the aspect of activating the DRX active state in the discontinuous monitoring mechanism to receive the low power indication information sent by the network device and starting the first timer to start timing is specifically implemented as follows:

[0300] The transceiver module 1802 is configured to receive low power consumption indication information sent by a network device when a discontinuous monitoring mechanism activates a DRX active state;

[0301] The processing module 1801 is configured to trigger the first timer to start timing if the first indication information in the low power consumption indication information indicates triggering the first timer.

[0302] In an alternative implementation:

[0303] The transceiver module 1802 is further configured to monitor the PDCCH in the DRX active state if the first indication information in the low power consumption indication information indicates not to trigger the first timer.

[0304] This method does not rely on the first timer mentioned above, but monitors PDCCH through other methods (such as traditional methods). This can avoid the problem of increased blind detection time of PDCCH by the terminal device due to triggering timer1 in some scenarios, thereby avoiding excessive power consumption of the terminal device.

[0305] In yet another optional implementation:

[0306] The transceiver module 1802 is further configured to receive low power consumption indication information sent by the network device in the DRX off state when the discontinuous monitoring mechanism is deactivated, and the processing module 1801 is further configured to start a second timer to start timing;

[0307] The processing module 1801 is further configured to switch from the first working mode to the second working mode in response to the low power consumption indication information;

[0308] The transceiver module 1802 is further configured to monitor a second signal sent by the network device during the timing of the second timer, wherein the second signal includes a physical downlink control channel PDCCH and / or a measurement signal.

[0309] In this way, since the DRX off state triggers the timer, the terminal device can be triggered to send and receive data during the DRX off phase, thereby reducing latency.

[0310] In yet another optional implementation, the timing duration of the first timer is configured by the network device.

[0311] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up receiving signal LP-WUS.

[0312] In yet another optional implementation, the first information is PDCCH, and the first information is scrambled by a cell radio network temporary identifier C-RNTI.

The processing module 1801 and the transceiver module 1802 in the communication device may respectively perform the following operations:

The coupling in the embodiment of the present application is an indirect coupling or communication connection between devices, units or modules, which may be electrical, mechanical or other forms, and is used for information exchange between devices, units or modules. The processor 1920 may operate in conjunction with the memory 1930. The processor 1920 may execute program instructions stored in the memory 1930. Optionally, at least one of the above one or more memories may be included in the processor.

[0347] The specific connection medium between the transceiver 1910, the processor 1920 and the memory 1930 is not limited in the embodiment of the present application. Fig.19 The memory 1930, the processor 1920 and the transceiver 1910 are connected via a bus 1940. Fig.19 The connections between the other components are shown in bold lines, which are only for illustration and are not intended to be limiting. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Fig.19 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.
