Description

A communication method and related device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on November 21, 2023, with application number 202311563891.7, and invention name “A communication method and related device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communication technology, and in particular to a communication method and related devices. Background Art

[0003] A new feature proposed by the 3GPP project involves designing a separate low-power receiver to reduce the energy consumption of user equipment (UE) during blind detection of the Physical Downlink Control Channel (PDCCH). When data is transmitted to the UE, the network first sends a low-power wake-up signal (LP-WUS) to wake up the primary receiver, which then performs blind detection of the PDCCH and receives the corresponding data schedule. Because low-power receivers (also known as auxiliary receivers or LP-WUS) typically use low-speed, low-precision analog-to-digital converters (ADCs), low-precision local oscillators, and low-complexity digital processing modules, their power consumption is significantly lower than that of traditional primary receivers. Therefore, by utilizing the low-power receiver to receive the wake-up signal and then waking up the primary receiver to receive the data schedule, UE power consumption can be reduced. Figure 1 shows the relationship between the primary receiver 102 and the low-power receiver 101. When the low-power receiver 101 is turned on, the primary receiver 102 can 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.

[0004] Currently, there are many methods for improving LP-WUS monitoring performance, such as time- and frequency-domain repetition, energy-focused transmission, transmit diversity, and frequency modulation. These technologies require advance notification to the UE. For example, the network needs to inform the UE of the LP-WUS transmission method, such as the number of signal repetitions or whether frequency hopping is used, before the UE monitors the LP-WUS. Ensuring accurate PDCCH monitoring remains a pressing technical challenge for those skilled in the art in improving LP-WUS monitoring performance.

[0005] Summary of the Invention

[0006] 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).

[0007] In a first aspect, an embodiment of the present application provides a communication method, the method comprising:

[0008] sending low power indication information to the terminal device in the DRX active state activated by the discontinuous monitoring mechanism, and starting a first timer, wherein the low power indication information is used to instruct the terminal device to switch from the first operating mode to the second operating mode, and the power consumption of the terminal device in the second operating mode is greater than the power consumption in the first operating mode;

[0009] 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.

[0010] 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.

[0011] In an optional implementation, the method further includes:

[0012] When the first information is transmitted, the first timer is stopped and the first timer is initialized.

[0013] 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 sending and receiving other data, thereby improving communication efficiency and time resource utilization.

[0014] In an optional implementation, the first information is a signal of non-scheduled initial transmission data.

[0015] In yet another optional implementation, the low power consumption indication information includes first indication information, where the first indication information is used to indicate whether to trigger the first timer.

[0016] It can be understood that the first indication information is used in the low-power indication information to indicate whether to trigger the first timer. 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 that PDCCH is received and monitoring power consumption is reduced.

[0017] In yet another optional implementation, the method further includes:

[0018] 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;

[0019] 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.

[0020] In this implementation, low-power indication information can be sent even in the DRX off state, triggering the terminal device to subsequently switch from the first operating mode to the second operating mode, thereby receiving the second signal, thereby meeting the mode switching requirements of more scenarios. Furthermore, because the DRX off state triggers a timer, it can trigger the terminal device to send and receive data during the DRX off phase, reducing latency.

[0021] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up reception signal LP-WUS.

[0022] In another optional implementation, the first information is a PDCCH, and the first information is scrambled by a cell radio network temporary identifier C-RNTI.

[0023] In a second aspect, an embodiment of the present application provides a communication method, the method comprising:

[0024] receiving low power indication information sent by a network device in a DRX active state activated by a discontinuous monitoring mechanism, and starting a first timer, wherein the low power indication information is used to indicate switching from the first operating mode to the second operating mode;

[0025] In response to the low power consumption indication information, switching from the first operating mode to the second operating mode, wherein power consumption in the second operating mode is greater than power consumption in the first operating mode;

[0026] During the counting 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 counting of the first timer belongs to the DRX active state.

[0027] 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.

[0028] In an optional implementation, the method further includes:

[0029] When the first information is monitored, the first timer is stopped and the first timer is initialized.

[0030] 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 sending and receiving other data, thereby improving communication efficiency and time resource utilization.

[0031] In yet another optional implementation, the first information is a signal of non-scheduled initial transmission data.

[0032] In yet another optional implementation, the low power consumption indication information includes first indication information, where the first indication information is used to indicate whether to trigger the first timer.

[0033] It can be understood that the first indication information is used in the low-power indication information to indicate whether to trigger the first timer. 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 that PDCCH is received and monitoring power consumption is reduced.

[0034] In yet another optional implementation, the receiving, in the DRX active state when the discontinuous monitoring mechanism is activated, low power consumption indication information sent by the network device and starting a first timer to start timing includes:

[0035] Receive low power indication information sent by network equipment in DRX active state when the discontinuous monitoring mechanism is activated;

[0036] 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.

[0037] In yet another optional implementation, the method further includes:

[0038] 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.

[0039] This method does not rely on the above-mentioned first timer, but monitors PDCCH through other methods (such as traditional methods). It 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.

[0040] In yet another optional implementation, the method further includes:

[0041] receiving low power indication information sent by the network device in the DRX off state when the discontinuous monitoring mechanism is deactivated, and starting a second timer;

[0042] In response to the low power consumption indication information, switching from the first operating mode to the second operating mode;

[0043] 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.

[0044] 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.

[0045] In yet another optional implementation, the timing duration of the first timer is configured by the network device.

[0046] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up reception signal LP-WUS.

[0047] In another optional implementation, the first information is a PDCCH, and the first information is scrambled by a cell radio network temporary identifier C-RNTI.

[0048] In a third aspect, an embodiment of the present application provides a communication method, the method comprising:

[0049] If the remaining duration is less than the reference duration, the discontinuous monitoring mechanism after the first moment activates the DRX active state and sends 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 determined to end at the first moment, and the first moment is the current moment;

[0050] 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.

[0051] In this method, by comparing the remaining time with the reference time, it is determined whether there is still time to switch from the first working mode to the second working mode by responding to the low power indication before the end of the DRX active state. If it is not in time, the low power indication information is not sent to trigger the switching process. If it is in time, the low power 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.

[0052] In an optional implementation, the reference duration is a configured duration representing the time from when the terminal device receives power consumption indication information to when it switches the first working mode to the second working mode.

[0057] 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;

[0058] 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.

[0059] In the method, by comparing the remaining time with the reference time, it is determined whether it is still possible to switch from the first working mode to the second working mode by responding to the low power indication before the DRX active state ends. If it is not possible, the low power indication information is not sent to trigger the switching process. If it is still possible, the low power 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.

[0060] In an optional implementation, the reference duration is a configured duration representing the time from when the terminal device receives power consumption indication information to when it switches the first working mode to the second working mode.

[0075] A target time for switching from the first operating mode to the second operating mode is determined according to the first configuration parameter.

[0076] 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.

[0148] As an example and not a 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 wearable devices that are intelligently designed and developed using wearable technology 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 achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, 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 smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0149] The various terminal devices described above, if located on a vehicle (e.g., placed inside or installed in a vehicle), can be considered vehicle-mounted terminal devices, which are also referred to as on-board units (OBUs). In the embodiments of the present application, the terminal device may also include a relay. Alternatively, any device capable of data communication with a base station can be considered a terminal device.

[0150] In the embodiments of the present application, the device for implementing the function of the terminal device can be a terminal device, or a device capable of supporting the terminal device to implement the function, such as a chip system, which can be installed in the terminal device. In the embodiments of the present application, the chip system can be composed of a chip, or it can include a chip and other discrete devices. In the technical solutions provided in the embodiments of the present application, the technical solutions provided in the embodiments of the present application are described by taking the terminal device as an example in which the device for implementing the function of the terminal is a terminal device.

[0151] 2) Network equipment, including, for example, access network (AN) equipment, such as a base station (e.g., access point), which can refer to a device in an access network that communicates with a wireless terminal device over the air interface through one or more cells, or, for example, a network device in a vehicle-to-everything (V2X) technology is a road side 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 attribute management of the air interface. For example, the network device may include a base transceiver station (BTS) in a global system for mobile communication (GSM) or a code division multiple access (CDMA) network, a NB (NodeB) in a wideband code division multiple access (WCDMA), an evolved base station (NodeB or eNB or e-NodeB, evolutionary Node B) in a long term evolution LTE system or an advanced long term evolution (LTE-A), or may also include a next generation node B (gNB) in a 5GNR system (also referred to as an NR system) or 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.

[0152] 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.

[0153] In an embodiment of the present application, the device for implementing the function of the network device may be a network device, or 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.

[0154] The embodiment of the present application considers introducing a discontinuous reception (DRX) mechanism into the transceiver link of LP-WUS. As shown in FIG4 , the embodiment of the present application considers allowing a terminal device (such as a UE) to monitor the PDCCH in the active state (active) of each DRX cycle. There is a timer in each DRX cycle, and at least one timer among multiple timers indicates the active state. The timer is generally divided into an onduration timer and an inactivity timer. 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.

[0155] When using a low-power receiver for LP-WUS monitoring, the terminal device can disable some functions of the main receiver, allowing the main receiver to enter a sleep state. When the network device requires the main receiver to enable corresponding functions (such as monitoring the PDCCH, or PDC), the terminal device's main receiver switches from sleep to active mode, but this process will experience a wake-up delay, as shown in Figure 5. Optionally, the network device and the terminal device can inform each other of the approximate wake-up delay.

[0156] The inventors of the present application have discovered that when the DRX mechanism is introduced into the LP-WUS transmission and reception link, the terminal device receives the LP-WUS. The LP-WUS may cause the DRX active duration to be extended, or may not cause the DRX active duration to be extended. These two situations will have different impacts on the processing of subsequent service functions (such as monitoring PDCCH), for example:

[0157] If the terminal device does not extend DRX active after receiving LP-WUS: Due to the limitations of the terminal device's main receiver wake-up delay and network scheduling, the network device may send PDCCH some time after sending LP-WUS. As shown in Figure 6, since DRX active is not extended, PDCCH appears outside DRX active, which may cause the terminal device to be unable to receive PDCCH.

[0158] If the terminal device receives LP-WUS to extend DRX active: the PDCCH of the initial transmission data may have been transmitted within the original DRX active period. If the terminal device continues to monitor the PDCCH during the additional extended delay (such as the interval indicated by the dotted line in Figure 7), the PDCCH monitored during this process may not be the PDCCH used to schedule the initial transmission data. Therefore, the monitoring process will reduce the energy saving gain of the terminal device.

[0159] Based on the above research findings, this application provides multiple methods to enable the terminal device to receive the PDCCH of the initial transmission data in DRX active 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.

[0160] Please refer to FIG8 , which shows a communication method provided in an embodiment of the present application. The method can be implemented based on the architecture shown in FIG2 or FIG3 , or based on other architectures. The method includes but is not limited to the following steps:

[0161] Step S801: The network device activates the DRX active state in the discontinuous monitoring mechanism to send low power indication information to the terminal device and starts the first timer to start timing.

[0162] 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.

[0163] In an embodiment of the present application, a first timer timer1 is added, and the first timer is started (or triggered) to start timing at the same time as the low power indication information is sent. The timing duration of the first timer can be pre-configured, and it will automatically turn off when the timing duration is reached. It can also be turned off 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.

[0164] In the embodiment of the present application, the network device specifically sends low power consumption indication information and starts a first timer in the DRX active state.

[0165] Step S802: The network device sends first information to the terminal device during the timing of the first timer.

[0166] 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 can also include multiple items of PDCCH, measurement signal, and other signals, such as two items.

[0167] As shown in FIG9 , the first information needs to be sent during the timing of the first timer.

[0168] Step S803: The network device stops the first timer after sending the first information.

[0169] As shown in Figure 10, 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.

[0170] Step S804: The terminal device receives low power indication information sent by the network device in the DRX active state activated by the discontinuous monitoring mechanism, and starts a first timer to start timing.

[0171] Among them, when the terminal device receives the low power consumption indication information shown, it starts the first timer to start timing. In an 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 a protocol, or the network device can send an indication information to the terminal device for configuration or indication, which is not limited here.

[0172] 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.

[0173] That is, the terminal device switches from the first operating mode to the second operating mode according to the indication of the low power indication information. Optionally, the first operating mode in the embodiment of the present application can be a mode in which a low power receiver (also called a secondary receiver, LP-WUR) receives signals, and the second operating mode can be a mode in which a main receiver receives signals.

[0174] Step S806: During the timing of the first timer, the terminal device monitors the first information sent by the network device.

[0175] Specifically, when the terminal device enters the second working mode, it can be used to monitor the first information. The first information includes the 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, as shown in Figure 11.

[0176] Optionally, the first information is a signal of non-scheduled initial transmission data, such as a PDCCH of non-scheduled initial transmission data.

[0177] 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.

[0178] Step S807: The terminal device stops the first timer when monitoring the first information.

[0179] In the embodiment of the present application, the first timer can be initialized after being stopped.

[0180] 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 information. For example, when the value of the bit is 1, it indicates that timer1 is triggered (or started); when the value of the bit is 0, it indicates that timer1 is not triggered.

[0181] In this optional implementation, there are two execution scenarios, as follows:

[0182] In case 1, low-power indication information sent by a network device is received in a DRX active state with the discontinuous monitoring mechanism activated; if the first indication information in the low-power indication information indicates triggering the first timer, then the first timer is triggered to start timing. In other words, triggering the first timer to start timing in step S804 requires a prerequisite, namely, the first indication information in the low-power indication information indicates triggering the first timer, such as the value of the corresponding bit in the first indication information being 1.

[0183] In case 1, 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.

[0184] Case 2: 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 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 DRX active state. In this case, there is no need to rely on the first timer to control the timing of monitoring PDCCH.

[0185] For the second case, it can avoid the problem of increasing the time for the terminal device to blindly detect the PDCCH due to triggering timer1 in some scenarios. For example, in the scenario shown in Figure 12, when the terminal device wakes up the main receiver (corresponding to the second working mode) by sending LP-WUS to receive the PDCCH (corresponding to the first information), the PDCCH is a PDCCH that is not scheduled for initial transmission data. The terminal device should stop monitoring the PDCCH at time 1 and enter the DRX off state. However, if timer1 is triggered, the terminal device will actually monitor the PDCCH until time 2, increasing the power consumption of the terminal device. Therefore, for the scenario shown in Figure 12, timer1 can be not triggered, thereby avoiding excessive power consumption of the terminal device.

[0186] 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. The terminal device can continuously monitor 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:

[0187] 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 above-mentioned 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 when triggered by 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 parameter.

[0188] 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.

[0189] Step S813: The network device stops the second timer when sending the second signal.

[0190] Step S814: The terminal device receives the low power indication information sent by the network device in the DRX off state with the discontinuous monitoring mechanism deactivated, and starts the second timer to start timing.

[0191] 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.

[0192] 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.

[0193] Step S817: The terminal device stops the second timer when detecting the second signal.

[0194] It should be noted that the implementation of steps S811-S817 can refer to the relevant implementation principles of steps S801-S807. The main differences between the two are:

[0195] 1. The network device sends the low power indication information in the DRX off state, and the terminal device also receives the low power indication information in the DRX off state.

[0196] 2. The timing duration of the second timer is configured to be longer than the timing duration of the first timer.

[0197] In the method described in FIG8 , since the first timer timer1 is triggered, there is sufficient time to receive the first information (such as PDCHH) within timer1, which can avoid as much as possible the problem of missing the reception of the first information due to the delay in switching to the second working mode. 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, thereby avoiding the problem of increasing the time for the terminal device to blindly detect the PDCCH due to triggering timer1 in some scenarios. Furthermore, a solution for triggering the timer in the DRX off state is also provided, which can trigger the terminal device to send and receive data during the DRX off phase, thereby reducing latency.

[0198] Please refer to FIG. 13 , which shows a communication method provided in an embodiment of the present application. The method can be implemented based on the architecture shown in FIG. 2 or FIG. 3 , or based on other architectures. The method includes but is not limited to the following steps:

[0199] Step S1301: If the remaining duration is less than the reference duration, the network device activates the DRX active state using the discontinuous monitoring mechanism after the first moment to send the first information to the terminal device.

[0200] 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 compare 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 or historical data. The reference duration can be configured by the network side or pre-defined by the protocol. Its function is to be used for reference comparison.

[0201] It should be noted that if the remaining duration is less than the reference duration, it is highly likely that the system cannot switch from the first operating mode 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 sent directly, 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.

[0202] 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 size relationship between the remaining time and the reference time, and determines whether to send the low power consumption indication information based on the size relationship.

[0203] Step S1302: If the remaining duration is less than the reference duration, the terminal device activates the DRX active state using the discontinuous monitoring mechanism after the first moment to receive the first information sent by the network device.

[0204] 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 DRX active state after the first moment receives the first information sent by the network device instead of the low power indication information. Therefore, it is too late to complete the switching process by responding to the low power indication information.

[0205] Among them, step S1302 can occur when the terminal device is in the period of receiving low power indication information. The period of receiving low power indication information refers to when the relevant conditions for receiving low power 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 indication information. In an embodiment of the present application, when the terminal device meets the ability to receive low power indication information, it does not directly receive (or monitor) the low power indication information, but further determines the size relationship between the remaining time and the reference time, and determines whether to receive the low power indication information based on the size relationship.

[0206] Step S1303: If the remaining time is greater than the reference time, the network device sends low power consumption indication information to the terminal device after the first moment.

[0207] Specifically, 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; for example, the low power consumption indication information can be LP-WUS.

[0208] 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.

[0209] 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.

[0210] Step S1305: The terminal device responds to the low power consumption indication information and switches from the first operating mode to the second operating mode.

[0211] That is, the terminal device switches modes according to 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.

[0212] Step S1306: The terminal device receives the first information in the second working mode.

[0213] For example, a PDCCH or a measurement signal is received in the second working mode. Optionally, the first information may further include multiple items, such as two items, of the PDCCH, the measurement signal, and other signals.

[0214] In the method described in Figure 13, by comparing the remaining time with the reference time, it is determined whether there is still time to switch from the first working mode to the second working mode by responding to the low power indication before the end of the DRX active state. If it is too late, the low power indication information is not sent to trigger the switching process. If it is still in time, the low power 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.

[0215] Please refer to FIG. 14 , which shows a communication method provided in an embodiment of the present application. The method can be implemented based on the architecture shown in FIG. 2 or FIG. 3 , or based on other architectures. The method includes but is not limited to the following steps:

[0216] Step S1401: The network device generates a first configuration parameter.

[0217] Among them, the first configuration parameter includes a first duration, as shown in Figure 15, 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 indication information in a group of low power 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.

[0218] 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.

[0219] Optionally, the low power consumption indication information includes a low power consumption wake-up reception signal LP-WUS.

[0220] 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.

[0221] In an embodiment of the present application, the power consumption of the terminal device in the second operating mode is greater than the power consumption in the first operating mode. Optionally, the first operating mode may be a mode in which a low-power receiver (also known as a secondary receiver, LP-WUR) receives signals, and the second operating mode may be a mode in which a primary receiver receives signals.

[0222] Step S1402: The network device sends the first configuration parameter to the terminal device.

[0223] 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).

[0224] Step S1403: The network device sends first information to the terminal device.

[0225] 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.

[0226] The execution order of step S1403 and steps S1402 and S1404 is not limited here.

[0227] Step S1404: The terminal device receives the first configuration parameter sent by the network device.

[0228] 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.

[0229] Specifically, the terminal device determines the target time for switching from the first working mode to the second working mode based on 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, the following examples are provided:

[0230] In Case 1, the first configuration parameter further includes a second time, a first quantity value, a second duration, and a third duration, wherein:

[0231] The second time is used to indicate the monitoring start time of the first low power indication information in the group of low power indication information. The first low power indication information mentioned here refers to the low power indication with the earliest sending time.

[0232] The first quantity value is used to indicate the number of low power indication information in the set of low power indication information, and can also be understood as the number of repetitions of the low power indication information, such as the number of repetitions of LP-WUS, which is generally greater than 1.

[0233] The second duration is used to indicate the time occupied by the transmission of a single low-power indication information in the set 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 set of low-power indication information (or the time resources occupied) is the same.

[0234] 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, if 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 the transmission time of 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 2 is the third duration here. Optionally, the third durations corresponding to any two adjacent sets of low-power indication information are the same.

[0235] In this case, the terminal device specifically determines the target time based on the first duration, the second time, the first quantity value, the second duration, and the third duration. For example, as shown in FIG16 , the target time t2 satisfies the following relationship:

[0236] t2=first_time_of_Wus+(Number_of_repetition-1)*offset1+Number_of_repetition*time_length+offset2;

[0237] 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.

[0238] Case 2: The first configuration parameter also includes a time list and a second duration, where:

[0239] The moment list includes the monitoring start moment of each low power indication information in the set of low power indication information. It can be understood that each low power indication information has a monitoring start moment. Here, the monitoring start moment of each low power indication information is reflected in the form of a moment list and carried in the first configuration parameter, so as to be transmitted to the terminal device.

[0240] 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 of the second duration has been described above and will not be repeated here.

[0241] 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, as shown in FIG17 , the target time t2 satisfies the following relationship:

[0242] t2=first_time_of_Wus_list_last+time_length+offset2;

[0243] 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.

[0244] Case 3, the first configuration parameter further includes another time list, which includes the monitoring end time of each low power indication information in the set of low power indication information. In this case, the above start time t2 satisfies the following relationship:

[0245] t2=first_time_of_Wus_list_end+offset2;

[0246] Among them, first_time_of_Wus_list_end is the monitoring end time that is last in the time list, and offset2 is the first duration.

[0247] It is understandable that there are many other similar implementations, which will not be listed here one by one.

[0248] Step S1406: The terminal device switches from the first working mode to the second working mode at the target time.

[0249] 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 turning on the main receiver.

[0250] Step S1407: The terminal device receives the first information in the second working mode.

[0251] 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.

[0252] In the method described in Figure 14, the last low-power indication information in a group of low-power indication information is clearly used as a benchmark, and a specific time is offset backward as the switching timing from the first working mode to the second working mode. This avoids the problem of confusing, inappropriate or repeated switching timing when there are multiple low-power indication information, and improves switching efficiency and certainty.

[0253] The following describes a communication device according to an embodiment of the present application.

[0254] The present application divides the functional modules of the communication device according to the above-mentioned 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-mentioned integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in this application is schematic and is only a logical function division. There may be other division methods in actual implementation. The communication device of the embodiment of the present application will be described in detail below with reference to Figures 18 to 20.

[0255] Figure 18 is a schematic diagram of the structure of a communication device provided in an embodiment of the present application. As shown in Figure 18, 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 referred to as an interface, a communication interface, or a communication module.

[0256] In some embodiments of the present application, the communication device can be used to perform the actions performed by the transmitting end in the above method embodiments. For example, the transmitting end can be the device itself or a chip or functional module that can be configured in the device. The transceiver module 1802 is used to perform the operations related to the transmitting end and receiving in the above method embodiments, and the processing module 1801 is used to perform the operations related to the processing of the transmitting end in the above method embodiments. The processing module 1801 can perform the corresponding operations by calling a computer program or by performing the corresponding operations through the corresponding hardware circuit. The transceiver module 1802 can perform the transceiver operations independently or under the control of the processing module 1801.

[0257] For example, the communication device shown in FIG18 may be a network device or a component in a network device. The processing module 1801 and the transceiver module 1802 in the communication device may respectively perform the following operations:

[0258] The transceiver module 1802 is configured 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 configured to start a first timer, wherein the low power consumption indication information is used to instruct the terminal device to switch from the first operating mode to the second operating mode, and the power consumption of the terminal device in the second operating mode is greater than the power consumption in the first operating mode;

[0259] 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.

[0260] 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.

[0261] In one possible implementation:

[0262] The processing module 1801 is further configured to stop the first timer and initialize the first timer when the first information is sent.

[0263] 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 sending and receiving other data, thereby improving communication efficiency and time resource utilization.

[0264] In yet another optional implementation, the first information is a signal of non-scheduled initial transmission data.

[0265] In yet another optional implementation, the low power consumption indication information includes first indication information, where the first indication information is used to indicate whether to trigger the first timer.

[0266] It can be understood that the first indication information is used in the low-power indication information to indicate whether to trigger the first timer. 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 that PDCCH is received and monitoring power consumption is reduced.

[0267] In yet another optional implementation:

[0268] The transceiver module 1802 is further configured to send low power consumption indication information to the terminal device when the discontinuous monitoring mechanism is deactivated in the DRX off state. The processing module 1801 is further configured to start a second timer;

[0269] The transceiver module 1802 is further configured 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.

[0270] In this implementation, low-power indication information can be sent even in the DRX off state, triggering the terminal device to subsequently switch from the first operating mode to the second operating mode, and then receive the second signal, thus meeting the mode switching requirements of more scenarios. In this approach, because the DRX off state triggers the timer, it can trigger the terminal device to send and receive data during the DRX off phase, reducing latency.

[0271] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up reception signal LP-WUS.

[0272] In another optional implementation, the first information is a PDCCH, and the first information is scrambled by a cell radio network temporary identifier C-RNTI.

[0273] Using Figure 18 , in some other embodiments of the present application, the communication device shown in Figure 18 may be a network device or a component in a network device, and the processing module 1801 and the transceiver module 1802 in the communication device may respectively perform the following operations:

[0274] The transceiver module 1802 is configured to activate the DRX active state using a discontinuous monitoring mechanism after a first moment if the remaining duration is less than a reference duration and send first information to the terminal device, wherein the first information includes a physical downlink control channel (PDCCH) or a measurement signal, and the remaining duration is a duration from the first moment to a time when the DRX active state is determined to end at the first moment, where the first moment is the current moment;

[0275] 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.

[0276] In this method, by comparing the remaining time with the reference time, it is determined whether there is still time to switch from the first working mode to the second working mode by responding to the low power indication before the end of the DRX active state. If it is not in time, the low power indication information is not sent to trigger the switching process. If it is in time, the low power 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.

[0277] In an optional implementation, the reference duration is a configured duration representing the time from when the terminal device receives power consumption indication information to when the terminal device switches the first working mode to the second working mode.

[0278] 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] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up reception signal LP-WUS.

[0280] Using Figure 18 , in some other embodiments of the present application, the communication device shown in Figure 18 may be a network device or a component in a network device, and the processing module 1801 and the transceiver module 1802 in the communication device may respectively perform the following operations:

[0281] Processing module 1801 is configured to generate a first configuration parameter, wherein the first configuration parameter includes a first duration, the first duration being used to indicate a time interval between a moment when a terminal device switches from a first operating mode to a second operating mode and an end moment of a last low-power indication information in a set of low-power indication information, wherein the power consumption of the terminal device in the second operating mode is greater than the power consumption in the first operating mode;

[0282] The transceiver module 1802 is used to send the first configuration parameter to the terminal device.

[0283] 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. This avoids the problem of confusing, inappropriate or repeated switching timing when there are multiple low-power indication information, and improves switching efficiency and certainty.

[0284] In an optional implementation:

[0285] 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.

[0286] 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 indication information in the set of low-power indication information, the first quantity value is used to indicate the number of low-power indication information in the set of low-power indication information, the second duration is used to indicate the time occupied by the transmission of a single low-power indication information in the set of low-power indication information, and the third duration is used to indicate the time distance between adjacent low-power indication information in the set of low-power indication information.

[0287] In another optional implementation, the first configuration parameter also includes a time list and a second duration, the time list includes the starting time of each low power indication information in the set of low power indication information, and the second duration is used to indicate the time occupied by the transmission of a single low power indication information in the set of low power indication information.

[0288] In yet another optional implementation, the signals carried by the set of low power consumption indication information are the same.

[0289] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up reception signal LP-WUS.

[0290] Using Figure 18, in some other embodiments of the present application, illustratively, the communication device shown in Figure 18 may be a terminal device or a component in a terminal device, and the processing module 1801 and the transceiver module 1802 in the communication device may respectively perform the following operations:

[0291] The transceiver module 1802 is configured to receive low power indication information sent by a network device in a DRX active state activated by a discontinuous monitoring mechanism, and the processing module 1801 is configured to start a first timer, wherein the low power indication information is used to indicate switching from the first operating mode to the second operating mode;

[0292] The processing module 1801 is configured to switch from the first operating mode to the second operating mode in response to the low power consumption indication information, wherein the power consumption in the second operating mode is greater than the power consumption in the first operating mode;

[0293] The transceiver module 1802 is configured to monitor 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.

[0294] 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.

[0295] In an optional implementation:

[0296] The processing module 1801 is configured to stop the first timer and initialize the first timer when the first information is monitored.

[0297] 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 sending and receiving other data, thereby improving communication efficiency and time resource utilization.

[0298] In yet another optional implementation, the first information is a signal of non-scheduled initial transmission data.

[0299] In yet another optional implementation, the low power consumption indication information includes first indication information, where the first indication information is used to indicate whether to trigger the first timer.

[0300] It can be understood that the first indication information is used in the low-power indication information to indicate whether to trigger the first timer. 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 that PDCCH is received and monitoring power consumption is reduced.

[0301] 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:

[0302] The transceiver module 1802 is configured to receive low power consumption indication information sent by a network device when the DRX active state is activated by the discontinuous monitoring mechanism;

[0303] 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.

[0304] In an optional implementation:

[0305] 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.

[0306] This method does not rely on the above-mentioned first timer, but monitors PDCCH through other methods (such as traditional methods). It 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.

[0307] In yet another optional implementation:

[0308] The transceiver module 1802 is further configured to receive low power consumption indication information sent by the network device when the discontinuous monitoring mechanism is deactivated in the DRX off state, and the processing module 1801 is further configured to start a second timer to start timing;

[0309] The processing module 1801 is further configured to switch from the first operating mode to the second operating mode in response to the low power consumption indication information;

[0310] 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.

[0311] 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.

[0312] In yet another optional implementation, the timing duration of the first timer is configured by the network device.

[0313] In yet another optional implementation, the low power consumption indication information includes a low power consumption wake-up reception signal LP-WUS.

[0314] In yet another optional implementation, the first information is a PDCCH, and the first information is scrambled by a cell radio network temporary identifier C-RNTI.

[0315] Using Figure 18, in some other embodiments of the present application, illustratively, the communication device shown in Figure 18 may be a terminal device or a component in a terminal device, and the processing module 1801 and the transceiver module 1802 in the communication device may respectively perform the following operations:

[0316] The transceiver module 1802 is configured to activate the DRX active state using a discontinuous monitoring mechanism after a first moment if the remaining duration is less than a reference duration, and receive first information sent by a network device, wherein the first information includes a physical downlink control channel (PDCCH) and / or a measurement signal, and the remaining duration is a duration from the first moment to an end time of the DRX active state, where the first moment is a current moment;

[0317] The transceiver module 1802 is further configured to receive low power consumption indication information sent by the network device after the first moment if the remaining time is greater than the reference time;

[0318] The processing module 1801 is used to respond to the low power consumption indication information and 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.

[0319] In this method, by comparing the remaining time with the reference time, it is determined whether there is still time to switch from the first working mode to the second working mode by responding to the low power indication before the end of the DRX active state. If it is not in time, the low power indication information is not sent to trigger the switching process. If it is in time, the low power 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.

[0325] The processing module 1801 is configured to determine a target time for switching from the first operating mode to the second operating mode according to the first configuration parameters.

[0326] 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. This avoids the problem of confusing, inappropriate or repeated switching timing when there are multiple low-power indication information, and improves switching efficiency and certainty.

[0327] In an optional implementation:

[0328] The processing module 1801 is further configured to switch from the first operating mode to the second operating mode at the target moment.

[0329] In yet another optional implementation:

[0330] The transceiver module 1802 is further configured to receive first information in the second working mode, wherein the first information includes a physical downlink control channel PDCCH and / or a measurement signal.

[0341] The specific descriptions of the transceiver module and the processing module shown in the above embodiments are only examples. For the specific functions or execution steps of the transceiver module and the processing module, please refer to the above method embodiments and will not be described in detail here.

[0343] The following description is for illustrative purposes only and does not limit the product form of the communication device of the embodiment of the present application to this description.

[0344] In one possible implementation, in the communication device shown in FIG18 , the processing module 1801 may be one or more processors, and the transceiver module 1802 may be a transceiver, or the transceiver module 1802 may be a transmitting module and a receiving module, wherein the transmitting module may be a transmitter and the receiving module may be a receiver, and the transmitting module and the receiving module are integrated into a single device, such as a transceiver.

During the execution of the above method, the process of sending information in the above method may be the process of the processor outputting the above information. When outputting the above information, the processor outputs the above information to the transceiver so that the transceiver transmits it. After being output by the processor, the above information may also need to undergo other processing before reaching the transceiver. Similarly, the process of receiving information in the above method may be the process of the processor receiving the above information as input. When the processor receives the input information, the transceiver receives the above information and inputs it into the processor. Furthermore, after the transceiver receives the above information, the above information may need to be processed further before being input into the processor.

[0346] In the above-mentioned embodiments, the description of the relevant steps and information can be referred to the introduction in the above method embodiment, and will not be described in detail here.

[0347] In various implementations of the communication device shown in FIG19 , the transceiver may include a receiver and a transmitter, wherein the receiver is configured to perform a receiving function (or operation) and the transmitter is configured to perform a transmitting function (or operation). The transceiver is configured to communicate with other devices / apparatuses via a transmission medium.

[0348] Optionally, the communication device 190 may further include one or more memories 1930 for storing program instructions and / or data. The memory 1930 is coupled to the processor 1920. The coupling in the embodiment of the present application is an indirect coupling or communication connection between devices, units or modules, which can 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-mentioned one or more memories may be included in the processor.

[0349] The specific connection medium between the transceiver 1910, processor 1920, and memory 1930 is not limited in the embodiments of the present application. In Figure 19, the memory 1930, processor 1920, and transceiver 1910 are connected via a bus 1940. The bus is represented by a bold line in Figure 19. The connection methods between other components are only for schematic illustration and are not limiting. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of illustration, only one bold line is used in Figure 19, but this does not mean that there is only one bus or one type of bus.

[0350] In the embodiments of the present application, the processor may be a general-purpose processor, a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, etc., and may implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present application. The general-purpose processor may be a microprocessor or any conventional processor, etc. The steps of the methods disclosed in the embodiments of the present application may be directly implemented as being executed by a hardware processor, or may be executed by a combination of hardware and software modules in the processor, etc.

[0351] In the embodiment of the present application, memory may include but is not limited to non-volatile memories such as hard disk drive (HDD) or solid-state drive (SSD), random access memory (RAM), erasable programmable read-only memory (EPROM), read-only memory (ROM) or portable read-only memory (CD-ROM), etc. Memory is any storage medium that can be used to carry or store program code in the form of instructions or data structures, and can be read and / or written by a computer (such as the communication device shown in the present application), but is not limited thereto. The memory in the embodiment of the present application can also be a circuit or other arbitrarily capable of realizing a storage function, for storing program instructions and / or data.

[0352] The processor 1920 is primarily used to process communication protocols and communication data, control the entire communication device, execute software programs, and process software program data. The memory 1930 is primarily used to store software programs and data. The transceiver 1910 may include a control circuit and an antenna. The control circuit is primarily used to convert baseband signals into radio frequency signals and process radio frequency signals. The antenna is primarily used to transmit and receive radio frequency signals in the form of electromagnetic waves. Input and output devices, such as a touch screen, display, and keyboard, are primarily used to receive user input and output data to the user.

[0353] When the communication device is powered on, the processor 1920 can read the software program in the memory 1930, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be sent wirelessly, the processor 1920 performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal to the outside in the form of electromagnetic waves via the antenna. When data is sent to the communication device, the radio frequency circuit receives the radio frequency signal via the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 1920. The processor 1920 converts the baseband signal into data and processes the data.

[0354] In another implementation, the RF circuit and antenna may be provided independently of the processor performing baseband processing. For example, in a distributed scenario, the RF circuit and antenna may be remotely arranged independent of the communication device.
