Description

Communication method and communication apparatus

[0001] This application claims priority from the Chinese Patent Application No. 202411126507.1 filed on August 15, 2024, and entitled "A communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to a communication method and communication apparatus. BACKGROUND

[0003] In order to reduce the power consumption of the terminal, the terminal can use a low power wake up receiver (LP-WUR) to receive a low power wake up signal (LP-WUS), trigger the main receiver to start up through the LP-WUS, and use the main receiver to monitor possible incoming signaling or data. If the LP-WUS indicates that the main receiver does not need to be woken up, the main receiver can be in a sleep state to save energy. Generally, the network device configures a monitoring occasion (MO) for the terminal to monitor the LP-WUS, and the network device only sends the LP-WUS to the terminal at the MO.

[0004] In a discontinuous reception (DRX) working mode, when the terminal in a radio resource control (RRC) connected state wakes up the main receiver through the LP-WUS, the LP-WUS is used to indicate whether the terminal starts the main receiver to perform physical downlink control channel (PDCCH) monitoring from the time domain starting position of the next drx-onDurationTimer. The time domain resource position of the MO and the time domain resource position of the drx-onDurationTimer are configured by the network device, so the interval between the two is determined by the network device. As shown in FIG. 1, the network device has buffered service data at the MO, the network device sends the LP-WUS to the terminal at the MO, and the terminal starts the main receiver at the next drx-onDurationTimer after receiving the LP-WUS, so that the network device and the terminal can start to transmit service data.

[0005] It can be understood that when the interval between the end position of the MO of the terminal receiving the LP-WUS and the start position of the next drx-onDurationTimer is large, the delay of the terminal receiving the service data is increased, which may cause the service transmission to fail. SUMMARY

[0006] The embodiments of the present application provide a communication method and a communication device, which are beneficial to reduce the transmission delay of service data and improve the efficiency of the terminal receiving the service data.

[0007] In a first aspect, the present application provides a communication method, which is executed by a terminal or a module applied to the terminal. Taking the terminal executing the method as an example, the method comprises: receiving, by the terminal in a first MO, a low-power consumption signal, the low-power consumption signal being used to indicate whether to monitor a PDCCH or the low-power consumption signal being used to indicate to monitor the PDCCH, the PDCCH comprising scheduling information of a first service. If a first condition is met, the terminal starts a first timer and monitors the PDCCH during running of the first timer, the start position of the first timer being different from the start position of a drx-onDurationTimer. If the first condition is not met, the terminal starts the drx-onDurationTimer and monitors the PDCCH during running of the drx-onDurationTimer.

[0008] It needs to be understood that the time interval between the timer for monitoring the PDCCH (comprising the scheduling information of the first service) and the first MO after the terminal receives the low-power consumption signal in the first MO will affect the delay of the terminal receiving the data of the first service. Generally, the longer the time interval between the timer for monitoring the PDCCH and the first MO, the greater the service delay of the terminal receiving the data of the first service. Based on the method described in the first aspect, the start position of the first timer is different from the start position of the drx-onDurationTimer, so the service delay caused by the terminal monitoring the PDCCH during running of the first timer is different from the service delay caused by the terminal monitoring the PDCCH during running of the drx-onDurationTimer. The terminal selects to start the first timer or the drx-onDurationTimer to monitor the PDCCH after receiving the low-power consumption signal through the first condition, so as to flexibly adjust the service delay of the terminal receiving the first service, which is beneficial to reduce the transmission delay of service data and improve the efficiency of the terminal receiving the service data.

[0009] In a possible implementation, the start position of the first timer is later than the end position of the first MO, the start position of the drx-onDurationTimer is later than the end position of the first MO, the interval between the start position of the first timer and the start position of the drx-onDurationTimer is less than the length of the discontinuous reception cycle, the start position of the first timer is earlier than the start position of the drx-onDurationTimer, and the interval between the start position of the first MO and the start position of the drx-onDurationTimer is less than the length of the discontinuous reception cycle.

[0010] Based on the possible implementation, the start position of the first timer and the start position of the drx-onDurationTimer are both later than the end position of the first MO, the start position of the first timer is earlier than the start position of the drx-onDurationTimer, and the service delay caused by starting the first timer to monitor the PDCCH is less than the service delay caused by starting the drx-onDurationTimer to monitor the PDCCH, thereby facilitating flexible adjustment of the service delay of the terminal receiving the first service and facilitating reduction of the transmission delay of the service data.

[0011] In a possible implementation, the first condition includes at least one of the following:

[0012] The packet delay budget (PDB) of the first service is less than a first threshold, and the interval between the end position of the first MO and the start position of the drx-onDurationTimer is greater than a second threshold; or

[0013] The first indication information including a first offset value is received, the first offset value being the interval between the start position of the first timer and the start position of the drx-onDurationTimer; or

[0014] The first indication information including a first offset value is received, the first offset value being the interval between the start position of the first timer and the start position of the drx-onDurationTimer, and the first offset value is not 0; or

[0015] The second indication information including the related parameters of the first timer is received, the related parameters of the first timer including at least one of the following: the duration of the first timer, the length of the first timer, the start position of the first timer, or the interval between the start position of the first timer and the start position of the drx-onDurationTimer.

[0016] Based on the possible implementation, whether to start the first timer to monitor the PDCCH can be determined by various first conditions, thereby facilitating to improve the flexibility of starting the first timer.

[0017] In a possible implementation, the terminal receives a first message used to determine the PDB of the first service; or the PDB of the first service is included in the low-power consumption signal.

[0018] Based on the possible implementation, the terminal can determine the PDB of the first service through the low-power consumption signal or the first message, thereby facilitating to improve the flexibility of the terminal in obtaining the PDB of the first service.

[0019] In a possible implementation, an interval between a receiving position of the first message and a starting position of a measurement interval is T1, the T1 is a positive number, and the measurement interval is determined by a second message sent by the network device; or an interval between the receiving position of the first message and an ending position of the measurement interval is T2, the T2 is a positive number; or the receiving position of the first message is during running of the first timer or the drx-onDurationTimer or the second timer or the non-active timer drx-InactivityTimer; or an interval between the receiving position of the first message and a receiving position of a synchronization signal block (SSB) is less than a third threshold, and the receiving position of the SSB is determined by the network device; or the receiving position of the first message is during feedback of a channel status information reference signal (CSI-RS).

[0020] Based on the possible implementation, by restricting the interval between the receiving position of the first message and the starting position of the measurement interval, or receiving the first message during running of the timer, or by restricting the interval between the receiving position of the first message and the receiving position of the SSB, or receiving the first message during feedback of the CSI-RS, it is favorable to reduce the frequency of starting the main receiver, thereby saving power consumption.

[0021] In a possible implementation, the first message includes an RRC reconfiguration message (RRC Reconfiguration).

[0022] In a possible implementation, the terminal receives a third message including whether to support starting the first timer to monitor the PDCCH; or the third message includes supporting starting the first timer to monitor the PDCCH.

[0023] By implementing the possible implementation, only when the first message indicates that the first timer for PDCCH monitoring is supported to be started, the terminal starts the first timer in the case that the first condition is met, which is beneficial to adapt the operation of the terminal starting the first timer to the current communication scenario.

[0024] In a possible implementation, the terminal receives a fourth message, the fourth message being used to indicate to start the second timer, and a length of the second timer being a positive number; wherein the fourth message comprises third indication information, the third indication information indicating that the PDCCH is monitored during running of the first timer or running of the second timer, and the second timer is started.

[0025] By implementing the possible implementation, after the terminal monitors the PDCCH during running of the first timer or the second timer, the second timer is restarted to prolong a time length during which the terminal starts the main receiver to monitor the PDCCH, which is beneficial to guarantee stable transmission of data of the first service.

[0026] In a possible implementation, in a first case, a value set of a modulation and coding scheme (MCS) for transmitting the first service is a first set; the first case is a case that the fourth message is not received, or the first case is a case that the fourth message is received and a length of the second timer included in the fourth message is 0; in a second case, the value set of the MCS for transmitting the first service is a second set; the second case is a case that the fourth message is received and the length of the second timer included in the fourth message is not 0; wherein a minimum value of elements in the first set is greater than a maximum value of elements in the second set.

[0027] By implementing the possible implementation, in the case that the second timer is started, the terminal can use a smaller MCS to receive data of the first service for a longer time, which is beneficial to improve data transmission reliability of the first service. In the case that the second timer is not started, the terminal can use a larger MCS to receive data of the first service for a shorter time, which is beneficial to improve a data transmission rate of the first data.

[0028] In a possible implementation, the terminal receives a fifth message, the fifth message being used to determine the length of the first timer and / or the length of the second timer; wherein the length of the first timer is the length of a drx-onDurationTimer configured by the network device or the length of a drx-InactivityTimer; the length of the second timer is the length of the drx-onDurationTimer configured by the network device or the length of the drx-InactivityTimer.

[0029] Alternatively, the length of the first timer is predefined, or the length of the second timer is predefined.

[0030] In a second aspect, the present application provides a communication method, which is executed by a network device or a module applied to a network device. Taking the execution of the method by the network device as an example, the method comprises: the network device sends a low-power consumption signal in a first MO, the low-power consumption signal being used to indicate whether to monitor a PDCCH or the low-power consumption signal being used to indicate to monitor the PDCCH, the PDCCH comprising scheduling information of a first service; if a first condition is met, the network device starts a first timer and sends the PDCCH during running of the first timer, the starting position of the first timer being different from the starting position of a drx-onDurationTimer; if the first condition is not met, the network device starts the drx-onDurationTimer and sends the PDCCH during running of the drx-onDurationTimer.

[0031] The beneficial effects obtained based on the method provided in the second aspect can refer to the description of the beneficial effects obtained based on the method provided in the first aspect, which will not be repeated here.

[0065] In order to facilitate the specific understanding of the embodiments of the present application, the system architecture related to the embodiments of the present application will be introduced first.

[0066] FIG. 2 is a schematic diagram of an architecture of a communication system 1000 to which embodiments of the present application are applied. As shown in FIG. 2, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 can also include the Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 2, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 2, collectively referred to as 120). The RAN 100 can also include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 2). The terminal 120 is connected to the RAN node 110 in a wireless manner, and the RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrating the logical functions of the core network device and the logical functions of the RAN node. The terminals and the terminals, and the RAN nodes and the RAN nodes can be connected to each other in a wired or wireless manner. It should be noted that the RAN node 110 can also be referred to as a network device 110 hereinafter.

[0067] The RAN 100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, and future wireless access systems defined in the 3rd generation partnership project (3GPP). The RAN 100 can also include two or more different wireless access systems described above. The RAN 100 can also be an open RAN (O-RAN).

[0068] The RAN node, also referred to as a radio access network device, RAN entity, or access node, is used to help terminals access the communication system through wireless means. In one application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, or a base station in a future mobile communication system. The RAN node can be a macro base station (such as 110a in FIG. 2), a micro base station or an indoor station (such as 110b in FIG. 2), or a relay node or donor node.

[0069] In another application scenario, wireless access can be achieved for a terminal through cooperation of multiple RAN nodes, and different RAN nodes respectively implement part of functions of a base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU implements functions of a radio resource control protocol and a packet data convergence protocol (PDCP) of a base station, and can also implement a function of a service data adaptation protocol (SDAP); the DU implements functions of a radio link control layer and a medium access control (MAC) layer of a base station, and can also implement part of a physical layer or all of a physical layer; and specific descriptions about the protocol layers can refer to related technical specifications of 3GPP. The RU can be used to implement functions of transceiving a radio frequency signal. The CU and the DU can be two independent RAN nodes, or can be integrated in a same RAN node, for example, integrated in a baseband unit (BBU). The RU can be included in a radio frequency device, for example, included in a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes, CU-control plane and CU-user plane.

[0070] In different systems, the RAN node can have different names. For example, in an O-RAN system, the CU can be referred to as an open CU (O-CU), the DU can be referred to as an open DU (O-DU), and the RU can be referred to as an open RU (O-RU). The RAN node in the embodiments of the present application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. For example, the RAN node can be a server loaded with a corresponding software module. The embodiments of the present application do not limit specific technologies and specific device forms adopted by the RAN node. For ease of description, a base station is described as an example of the RAN node in the following.

[0071] A terminal is a device with wireless transceiver function, which can send signals to a base station or receive signals from a base station. A terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. A terminal can be widely applied in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, airplane, ship, robot, mechanical arm, smart home device, etc. Embodiments of the present application do not limit the specific technology and specific device form of the terminal.

[0072] A base station and a terminal can be fixed in position or movable. A base station and a terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water surface; can also be deployed on an airplane, balloon and artificial satellite. Embodiments of the present application do not limit the application scenarios of a base station and a terminal.

[0073] The roles of a base station and a terminal can be relative, for example, the helicopter or drone 120i in FIG. 2 can be configured as a mobile base station, which is a base station for those terminals 120j accessing to the wireless access network 100 through 120i; but for the base station 110a, 120i is a terminal, that is, 110a communicates with 120i through a wireless air interface protocol. Of course, 110a and 120i can also communicate through a base station-to-base station interface protocol, in which case, 120i is also a base station relative to 110a. Therefore, a base station and a terminal can be collectively referred to as a communication apparatus, 110a and 110b in FIG. 2 can be referred to as a communication apparatus with base station function, and 120a-120j in FIG. 2 can be referred to as a communication apparatus with terminal function.

[0074] A base station and a terminal, a base station and a base station, a terminal and a terminal can communicate through licensed spectrum, can also communicate through unlicensed spectrum, and can also communicate through both licensed spectrum and unlicensed spectrum; can communicate through spectrum below 6 gigahertz (GHz), can also communicate through spectrum above 6 GHz, and can also communicate through both spectrum below 6 GHz and spectrum above 6 GHz. Embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0075] In the embodiments of the present application, the functions of the base station can also be performed by a module (such as a chip) in the base station, or by a control subsystem containing the functions of the base station. The control subsystem containing the functions of the base station herein can be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal can also be performed by a module (such as a chip or modem) in the terminal, or by a device containing the functions of the terminal.

[0076] In the present application, the base station sends a downlink signal or downlink information to the terminal, and the downlink information is carried on a downlink channel; the terminal sends an uplink signal or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection with a cell controlled by the base station. The cell with which the terminal establishes a wireless connection is called the service cell of the terminal. When the terminal communicates with the service cell, it will also be interfered by signals from neighboring cells.

[0077] In the embodiments of the present application, the time domain symbol can be an orthogonal frequency division multiplexing (OFDM) symbol or a Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) symbol. If not specified, the symbol in the embodiments of the present application refers to a time domain symbol.

[0078] In order to facilitate the understanding of the related content of the embodiments of the present application, the following will explain some terms involved in the embodiments of the present application. This part is only for the convenience of understanding and cannot be regarded as the disclosure or specific limitation of the technical solutions of the present application.

[0079] 1. DRX mechanism

[0080] In the DRX mechanism, the terminal only turns on the receiver to receive downlink data and signaling in necessary time periods, and turns off the receiver to stop receiving downlink data and signaling in other time periods. In this way, the terminal does not need to continuously monitor the PDCCH, thereby achieving the effect of saving the power consumption of the terminal to prolong its use time.

[0081] In the DRX working mode, the terminal needs to periodically turn on the receiver to monitor possible incoming signaling. This period of time when the receiver is turned on is called the duration time or on duration time, and the length of the period is set by the parameter drx-onDurationTimer configured by RRC signaling. As shown in FIG. 3, the DRX cycle can be divided into an active period and a sleep period according to the state. The period in which the terminal turns on the receiver to monitor the PDCCH channel is called the DRX active period. Each DRX cycle consists of an on duration time and a sleep period that may exist. The on duration time is not necessarily followed by a sleep period, but can also be followed by an active period. The DRX active period includes the on duration time and the period in which the DRX related timers are in operation.

[0082] The base station configures the specific settings and value ranges of the functions, start, timing, stop, and timeout of the DRX related timers to the terminal through RRC signaling. The DRX related timers include a duration timer (drx-onDurationTimer), an inactivity timer (drx-InactivityTimer), and the like. Exemplarily, the drx-onDurationTimer and drx-InactivityTimer configured by the RRC signaling are shown in Table 1.

[0083] Table 1

[0084] 2, 5G Quality of Service Identifier (5G QoS Identifier, 5QI)

[0085] The 5QI is a scalar used to provide a reference for specific QoS forwarding behaviors (e.g., packet loss rate, packet delay budget) of a 5G Quality of Service (QoS) flow, which can be implemented in an access network by controlling the 5QI reference node specific parameters of the QoS forwarding process (e.g., scheduling weight, admission threshold, queue management threshold, link layer protocol configuration, etc.).

[0086] Generally, the mapping between 5QI and 5G QoS characteristics is indicated in 3GPP standard TS23.501 Table 5.7.4-1, one 5QI is used to index one 5G QoS characteristic (also can be called 5QI parameter). In the mapping relationship indicated in 3GPP standard TS23.501 Table 5.7.4-1, the 5QI parameter includes packet delay budget (PDB). PDB defines an upper limit of the time that a data packet can be delayed between the terminal and the N6 endpoint of the user plane function (UPF). PDB is applied to the downlink data packet received by the UPF through the N6 interface, and the uplink data packet sent by the terminal. For a certain 5QI, the PDB values of uplink and downlink are the same. In the case of 3GPP access, PDB is used to support the configuration of scheduling and link layer functions (for example, the setting of scheduling priority weight and hybrid automatic retransmission request (HARQ) target operating point). For a guaranteed bit rate (GBR) QoS flow using a delay-critical resource type, if the data burst does not exceed the maximum data burst volume (MDBV) within the time period of PDB and the QoS flow does not exceed the guaranteed flow bit rate (GFBR), the data packet whose delay exceeds PDB is counted as lost. For a GBR QoS flow of GBR resource type not exceeding GFBR, 98% of data packets will not experience a delay exceeding the PDB of 5QI.

[0087] 5G access network packet delay budget (5G-AN PDB) is determined by subtracting the static value of core network packet delay budget (CN PDB), which represents the delay between any N6 endpoint at UPF (for any UPF that can be selected for a PDU session) and 5G-AN in a given PDB.

[0088] Generally, the 5QI parameters corresponding to different services can be different. For example, in 3GPP standard TS23.501 Table 5.7.4-1, the PDB requirement for Non-Conversational Video or Buffered Streaming is 300 ms, and the PDB requirement for Live Gaming or vehicle to everything (V2X) messages is 50 ms. These PDBs include the core network to base station packet delay requirement and the base station to terminal packet delay requirement. It can be seen that the PDBs of Non-Conversational Video and Live Gaming are quite different.

[0089] 3、wake up radio (WUR)

[0090] The wake up radio can be understood as a function of reducing the power consumption of the terminal device. For the terminal device, the wake up radio refers to introducing a lower power (LP) interface on the basis of the traditional main module / main receiver. The main receiver has I / Q two-way, or the main receiver has decoding capability, or the main receiver has baseband processing capability, or the main receiver has the ability to demodulate signals or channels based on a larger order modulation mode, or the main receiver has the ability to receive data channels or signals, or the main receiver has the ability to receive control channels or signals, or the main receiver has the ability to receive physical broadcast channels (PBCH). The LP interface is implemented by a simple structure circuit or chip, and its power consumption is low. It should be noted that the specific form of the LP interface is not limited by the embodiments of the present application. For example, the LP interface can be implemented by a wake up receiver (WUR), LP-WUR, low-power radio (LR), wake up module or wake up circuit. The WUR in this paper can be a wake up radio, a wake up receiver. The WUR in this paper can be replaced by LP-WUR, LR, wake up module or wake up circuit.

[0091] For a terminal, the main receiver is mainly used for data / signaling transmission and / or reception, and if there is no need for data / signaling transmission and / or reception, the main receiver can be turned off or in a sleep state or mode. The WUR can be used to wake up the main receiver in a sleep state. For example, the terminal includes a main receiver and an LP-WUR, and a working schematic diagram of the LP-WUR provided in the present application is shown in FIG. 4. As shown in (a) of FIG. 4, in the case where the terminal is in an RRC connected state, when there is a need for data / signaling transmission and / or reception, if the LP-WUR detects (or understands to receive) a wake-up signal, the main receiver can be triggered to be in an open state. If the LP-WUR does not detect (or understand to receive) the wake-up signal, the main receiver can be in an off state or an ultra-deep sleep state. Alternatively, as shown in (b) of FIG. 4, in the case where the terminal is in an RRC connected state, when there is a need for data / signaling transmission and / or reception, if the LP-WUR detects a wake-up signal indicating to wake up the main receiver (for example, the bit state of the wake-up signal indicates to wake up the main receiver), the main receiver can be triggered to be in an open state. If the LP-WUR detects a wake-up signal indicating not to wake up the main receiver (for example, the bit state of the wake-up signal indicates not to wake up the main receiver), the main receiver can not be triggered, and the main receiver can be in an off state or an ultra-deep sleep state or a deep sleep state or a light sleep state or a micro sleep state.

[0092] Generally, the wake-up signal can have multiple mapping ways to time units, or the bit information of the wake-up signal can have multiple modulation ways, so the WUR can also receive the wake-up signal in different ways. For example, when the wake-up signal adopts on off keying (OOK) modulation (see the following description), the WUR in the terminal receives the wake-up signal in an envelope detection manner. For another example, when the wake-up signal adopts orthogonal frequency division multiplexing (OFDM) waveform transmission, the WUR in the terminal receives the wake-up signal in a phase detection manner. For convenience of description, in the embodiments of the present application, the wake-up signal adopts OFDM waveform transmission is referred to as the wake-up signal adopts OFDM modulation (see the following description).

[0093] Among them, the WUR receiving the wake-up signal in a phase detection manner can be regarded as a kind of receiver (for example, referred to as a first type of WUR), and the WUR receiving the wake-up signal in an envelope detection manner can be regarded as another kind of WUR (for example, referred to as a second type of WUR). The first type of WUR and the second type of WUR are relative, and there are multiple interpretations for the first type of WUR and the second type of WUR, which are illustrated below.

[0094] 1) The first type of WUR is an OFDM receiver, and the second type of WUR is an OOK receiver.

[0095] 2) The first type of WUR is a receiver with both I / Q paths, and the second type of WUR is a receiver with only one of the I / Q paths.

[0096] 3) The first type of WUR is a coherent receiver, and the second type of WUR is a non-coherent receiver.

[0097] 4) The first type of WUR is a coherent receiver with both I / Q paths, and the second type of WUR is a non-coherent receiver with only one of the I / Q paths.

[0098] 5) The first type of WUR receives a signal in a phase detection manner, and the second type of WUR receives a signal in an energy / power / amplitude detection manner. Alternatively, the first type of WUR can / able to detect phase information, and the second type of WUR can / able to detect signal energy / power / amplitude.

[0099] 6) The first type of WUR can receive a complex signal, and the second type of WUR cannot receive a complex signal (e.g., the second type of WUR receives a real signal).

[0100] 7) The first type of WUR has a phase detection capability, and the second type of WUR has an envelope detection capability or no phase detection capability. Alternatively, the first type of WUR supports receiving a signal in a phase detection manner, and the second type of WUR supports receiving a signal in an envelope detection manner. In the embodiments of the present application, the phase detection capability can be replaced by a correlation detection capability and a sequence detection capability.

[0101] 8) The first type of receiver can receive an OFDM signal, and the second type of receiver cannot receive an OFDM signal (e.g., the second type of receiver receives an OOK signal).

[0102] 4, Wake-up signal

[0103] In the present application, the wake-up signal received by the terminal through the LP-WUR is referred to as a low-power signal or LP-WUS, etc. For convenience of description, the low-power signal is taken as an example of the wake-up signal in the following description.

[0104] (1) Type of low-power signal

[0105] The application does not limit the type of low-power signal mentioned. For example, the low-power signal can be a low-power PDCCH, a low-power physical downlink shared channel (PDSCH), a low-power physical uplink shared channel (PUSCH), a low-power physical uplink control channel (PUCCH), a low-power synchronization signal / physical broadcast channel block (SSB), a low-power synchronization signal, a low-power tracking reference signal (TRS), a low-power channel state information reference signal (CSI-RS), a low-power positioning signal, a low-power sensing communication signal, a low-power sounding reference signal (SRS) signal, a low-power random access channel (RACH) signal, a low-power preamble signal, a low-power contention resolution message, a low-power downlink control information (DCI) signal, or a low-power uplink control information (UCI) signal, etc.

[0106] (2) Modulation method of low-power signal

[0107] It should be noted that the modulation method mentioned in the application includes but is not limited to OOK modulation and OFDM modulation. Among them:

[0108] OOK modulation is to use the presence or absence of a signal to represent digital information. The bit information corresponding to the signal is mapped to at least one time unit through OOK modulation, one time unit corresponds to one bit of information, and the bit information of the signal is determined by detecting whether there is a signal on the time unit. The signal on the time unit means that the signal amplitude on the time unit is not zero, such a time unit is also called ON time unit, or the time unit is in ON mode; correspondingly, the signal on the time unit means that the signal amplitude on the time unit is zero, such a time unit is also called OFF time unit, or the time unit is in OFF mode. Usually, if there is a sequence sent on the time unit, the time unit has a signal; if there is no sequence sent on the time unit, the time unit has no signal. For a time unit, the time unit is an ON time unit or the time unit is in ON mode, which can be decoded as 1; correspondingly, the time unit is an OFF time unit or the time unit is in OFF mode, which can be decoded as 0.

[0109] Exemplarily, taking the bit information of the signal as 1001 as an example, the principle of OOK modulation is shown in FIG. 5. The bit information 1001 is mapped to four time units (for example, time unit 1-time unit 4) in sequence through OOK modulation. It should be understood that time unit 1 and time unit 4 are time units with signals, and there is a sequence sent on time unit 1 and time unit 4. Time unit 2 and time unit 3 are time units without signals, and there is no sequence sent on time unit 2 and time unit 3. When the receiving end detects the sequence on time unit 1 and time unit 4, it can be decoded as 1. When the receiving end does not detect the sequence on time unit 2 and time unit 3, it can be decoded as 0. The receiving end combines the decoding of the four time units to obtain 1001. It can be seen that for OOK modulation, only one bit of information can be obtained in one time unit. It can be understood that the sequence of the time unit detected by the receiving end means that the receiving end detects the envelope of the signal on the time unit; correspondingly, the sequence of the time unit not detected by the receiving end means that the receiving end does not detect the envelope of the signal on the time unit.

[0110] OFDM modulation is to use the sequence information of a signal to represent digital information. Exemplarily, taking the sending end storing four sequences (i.e., sequence 0-sequence 3 in FIG. 6) as an example, the principle of OFDM modulation is shown in FIG. 6. Among them, the four sequences can be used to carry / carry 2 bits of information, for example, sequence 0 corresponds to bit information 00, sequence 1 corresponds to bit information 01, sequence 2 corresponds to bit information 10, and sequence 3 corresponds to bit information 11. In a time unit, the corresponding bit information is 01, then the access network device can determine that the sequence 1 corresponding to the bit information 01 according to the correspondence between the above four sequences and the bit information. The access network device can scramble the time unit by using the sequence 1.

[0111] As can be seen from FIG. 5 and FIG. 6, in addition to obtaining bit information through the ON / OFF mode in a time unit (as shown in FIG. 5), sequence information of the ON time unit can also be detected (as shown in FIG. 6). Compared with OOK modulation, OFDM modulation can obtain more bit information. Therefore, based on OFDM modulation, if a signal of the same length of bit information is to be transmitted, the signal occupies less time domain resource compared with OOK modulation. For example, a signal of the same length of bit information needs M symbols based on OFDM modulation, and needs N symbols based on OOK modulation, M is less than N, and M and N are positive numbers.

[0112] It should be noted that the modulation mode used by the wake-up signal depends on the capability of the receiver. Taking the foregoing WUR as an example, if the WUR is the first type of WUR, the bit information of the LP-WUS can be carried through the ON / OFF mode of the symbol and the sequence on the ON symbol. If the WUR is the second type of WUR, the bit information of the LP-WUS can be carried through the ON / OFF mode of the symbol. The signal corresponding to the first type of WUR is regarded as a type of signal (for example, referred to as a first type of signal), and the signal corresponding to the second type of WUR is regarded as another type of signal (for example, referred to as a second type of signal). Since the second type of WUR needs to occupy more time domain resource compared with the first type of WUR, the second type of signal is longer than the first type of signal, and the second type of signal can be referred to as a “long signal”, and the first type of signal can be referred to as a “short signal”. The first type of signal can also be referred to as a first type of low-power signal or a first type of LP-WUS, and correspondingly, the second type of signal can also be referred to as a second type of low-power signal or a second type of LP-WUS. Relatively, the power consumption required by the second type of WUR receiver for the second type of signal is greater than the power consumption required by the first type of WUR receiver for the first type of signal. The terminal device has greater energy saving gain for receiving the first type of signal by the first type of WUR. In addition, the detection performance of the second type of WUR is less than the detection performance of the first type of WUR, and the coverage performance supported by the second type of WUR is less than the coverage performance supported by the first type of WUR. Generally, if the second type of WUR is used to receive the signal, the coverage performance can be increased through coverage enhancement technology. For example, for the second type of WUR, the coverage performance can be improved by increasing the number of repeated transmissions of the signal.

[0113] It should be further explained that the time unit mentioned in the embodiments of the present application refers to the unit of time. The time unit can be a time unit of radio frame, subframe, slot, mini-slot, OFDM symbol, OOK symbol, fractional OFDM symbol, millisecond (ms) or fractional millisecond (for example, 1 / 32 ms). Alternatively, the time unit is a time unit of multiple slots, multiple subframes, multiple mini-slots, multiple OFDM symbols, multiple OOK symbols, a number of fractional OFDM symbols, a number of milliseconds (ms) or a number of fractional milliseconds. Wherein, one radio frame can include multiple subframes, one subframe can include one or more slots, and one slot can include at least one symbol. Alternatively, one radio frame can include multiple slots, and one slot can include at least one symbol. Alternatively, in the embodiments of the present application, the time unit mapped by OOK modulation can also be referred to as OOK time unit, and the time unit mapped by OFDM modulation can also be referred to as OFDM symbol. The OOK time unit in ON mode or the signal OOK time unit can also be referred to as OOK ON time unit. One OFDM symbol can include one or more OOK symbols. One OOK symbol can include multiple OFDM symbols.

[0114] Generally, in the DRX working mode, the network device can configure the terminal with an MO for monitoring the low-power consumption signal, and configure the terminal with a drx-onDurationTimer in each DRX cycle. The interval between the time domain resource position of the MO and the time domain resource position of the drx-onDurationTimer is determined by the network device. In the case that the terminal is in the RRC connected state and the main receiver of the terminal is in the sleep state, if the network device has buffered service data (or understood as service data to be transmitted to the terminal), the network device can send the low-power consumption signal to the terminal at the time domain position corresponding to the MO shown in FIG. 1, and the terminal turns on the main receiver at the next drx-onDurationTimer after the MO after receiving the low-power consumption signal, so that the network device and the terminal can start transmitting service data. It should be understood that the interval between the time domain position of the MO in which the terminal receives the low-power consumption signal and the time domain position of the drx-onDurationTimer in which the service data can be transmitted will affect the transmission delay of the service data.

[0115] When the interval between the time-domain end position of the MO and the time-domain start position of the drx-onDurationTimer is large, the transmission delay of the service data is increased, and when the transmission delay of the service data is greater than the PDB requirement of the service data, the service transmission can fail. When the interval between the time-domain end position of the MO and the time-domain start position of the drx-onDurationTimer is small, although the PDB requirement of the service data can be met, the main receiver of the terminal is frequently turned on, and the energy consumption of the terminal is increased.

[0116] In order to meet the transmission requirement of the service data while reducing the energy consumption of the terminal, the present application provides a communication method and a communication device. The communication method and the communication device provided by the embodiments of the present application are described in detail below in combination with the drawings.

[0117] FIG. 7 is a flow diagram of a communication method provided by an embodiment of the present application. As shown in FIG. 7, the communication method includes the following steps S701-S703, and the method execution subject shown in FIG. 7 is taken as an example to illustrate a terminal and a network device. It can be understood that the method execution subject shown in FIG. 7 can also be a module (for example, a chip) in the terminal and a module (for example, a chip, or a CU, or a DU) in the network device. Wherein:

[0118] S701, the network device sends a low-power consumption signal at a first MO.

[0119] Correspondingly, the terminal receives the low-power consumption signal at the first MO.

[0120] Optionally, the network device configures at least one MO for the terminal. The network device can send the low-power consumption signal to the terminal on any one of the at least one MO (or understood as on the time-domain position of any one of the MOs or in the time period corresponding to any one of the MOs). The terminal can monitor or receive the low-power consumption signal on the any one of the MOs. Optionally, the network device configures a time window for the terminal to monitor the low-power consumption signal, wherein the time window includes one or more continuous MOs. The network device can send the low-power consumption signal to the terminal on any one of the at least one MO (or understood as on the time-domain position of any one of the MOs or in the time period corresponding to any one of the MOs). The terminal can monitor or receive the low-power consumption signal on the any one of the MOs.

[0121] For ease of understanding, the MO used by the network device to send the low-power consumption signal or the MO in which the terminal receives the low-power consumption signal is denoted as the first MO.

[0122] For example, the network device configures MO1-MO3 for the terminal, and the network device can send the low-power signal to the terminal in the duration of any one of MO1-MO3. If the network device sends the low-power signal in MO2, or the terminal receives the low-power signal in MO2, the MO2 is regarded as the first MO mentioned in the application.

[0123] The low-power signal mentioned in the embodiments of the application is used to indicate whether the terminal monitors the PDCCH, or is used to instruct the terminal to monitor the PDCCH, or is used to indicate whether the terminal turns on the main receiver to monitor the PDCCH, or is used to instruct the terminal to turn on the main receiver to monitor the PDCCH. The PDCCH includes scheduling information of the first service, for example, the PDCCH carries DCI used to schedule the first service.

[0124] In order to save the power consumption of the terminal, the network device can configure a timer for the terminal after the first MO, so that the terminal can monitor the PDCCH during the running time of the timer, the terminal stops monitoring the PDCCH during the non-running time of the timer, or the main receiver of the terminal is in a sleep state during the non-running time of the timer. In this case, it can be understood that the low-power signal is used to indicate whether the terminal monitors the PDCCH during the running time of the timer after the first MO, or the low-power signal is used to instruct the terminal to monitor the PDCCH during the running time of the timer after the first MO.

[0125] The application takes the timer after the first MO as an example, which includes a first timer and a drx-onDurationTimer. The first timer is different from the drx-onDurationTimer, or the starting position of the first timer is different from the starting position of the drx-onDurationTimer, or the length of the first timer is different from the length of the drx-onDurationTimer. The starting position of the first timer is later than the end position of the first MO, and the starting position of the drx-onDurationTimer is later than the end position of the first MO. The starting position of the first timer is earlier than the starting position of the drx-onDurationTimer, and the interval between the first timer and the drx-onDurationTimer is less than the length of a DRX cycle, and the interval between the first MO and the drx-onDurationTimer is less than the length of a DRX cycle.

[0126] It can be understood that the first MO, the first timer and the drx-onDurationTimer belong to the same DRX cycle or are within the range of a DRX cycle length. For example, as shown in FIG. 8, the network device is configured with the MO, the first timer and the drx-onDurationTimer in each DRX cycle. Taking the first DRX cycle as an example, the starting position of the first MO in the first DRX cycle is before the starting position of the first timer, and the starting position of the first timer is before the starting position of the drx-onDurationTimer.

[0127] It should be understood that the "interval" mentioned in the present application includes at least one time unit. The "interval" mentioned in the present application can be any one of the interval between the starting position and the starting position, the interval between the ending position and the starting position, and the interval between the ending position and the ending position, if not otherwise specified. For example, the interval between the first timer and the drx-onDurationTimer can include / replace any one of the following: the interval between the starting position of the first timer and the starting position of the drx-onDurationTimer, the interval between the ending position of the first timer and the starting position of the drx-onDurationTimer, and the interval between the ending position of the first timer and the ending position of the drx-onDurationTimer. For another example, the interval between the first MO and the drx-onDurationTimer can include / replace any one of the following: the interval between the starting position of the first MO and the starting position of the drx-onDurationTimer, the interval between the ending position of the first MO and the starting position of the drx-onDurationTimer, and the interval between the ending position of the first MO and the ending position of the drx-onDurationTimer.

[0128] S702, if the first condition is met, the terminal starts the first timer and monitors the PDCCH during the running of the first timer.

[0129] Correspondingly, if the first condition is met, the network device starts the first timer and sends the PDCCH during the running of the first timer.

[0130] In combination with S702 and S703, it can be understood that the terminal device starts the first timer or starts the drx-onDurationTimer according to the first condition after receiving the low-power consumption signal in the first MO, or the network device starts the first timer or starts the drx-onDurationTimer according to the first condition after sending the low-power consumption signal in the first MO, or it can be understood that the terminal device and / or the network device determines whether to start the first timer according to the first condition. Wherein, in the case that the first condition is met, the terminal device and / or the network device starts the first timer as shown in S702. In the case that the first condition is not met, the terminal device and / or the network device starts the drx-onDurationTimer as shown in S703.

[0131] The first condition mentioned in the present application is described below. The first condition includes any one of the following conditions:

[0132] Condition 1: the PDB of the first service is less than a first threshold, and the interval between the end position of the first MO and the start position of the drx-onDurationTimer is greater than a second threshold.

[0133] In condition 1, the terminal device and / or the network device determines whether to start the first timer according to the PDB of the first service to be transmitted and the interval between the first MO and the drx-onDurationTimer. When the PDB of the first service is small (for example, less than the first threshold), and the interval between the first MO and the drx-onDurationTimer is large (for example, greater than the second threshold), it is considered that the first condition is met, and the terminal device and / or the network device starts the first timer.

[0134] Wherein, the specific values of the thresholds (including the first threshold and the second threshold, and the third threshold mentioned later) mentioned in the present application can be adjusted according to specific application scenarios, and the specific values of the thresholds are not limited in the present application. The specific values of the thresholds can be pre-defined by the protocol, or can be indicated to the terminal by the network device through the same indication signaling, or can be indicated to the terminal through different indication signaling respectively, and the present application does not make specific limitation on this.

[0135] In condition 1, before the terminal determines the first condition, the terminal needs to obtain the PDB of the first service.

[0136] In one possible implementation 1 of the terminal obtaining the PDB of the first service, the PDB of the first service is included in the low-power consumption signal of S701. That is, the network device indicates the terminal whether to monitor the PDCCH through the low-power consumption signal, and also indicates the PDB of the first service through the low-power consumption signal.

[0137] The low-power signal indicating the PDB of the first service includes, but is not limited to, the following implementations (Implementation 1-Implementation 3):

[0138] In Implementation 1, the bit information of the low-power signal can directly carry the value / level of the PDB of the first service. For example, the PDB has 4 candidate values / levels, and the low-power signal can indicate the 4 PDBs through 2 bits of information. For another example, in the case that the PDB has 4 candidate values / levels and the number of terminals served by the network device is N, the low-power signal can have 4N states, each state corresponding to a terminal and a PDB candidate value / level, and the low-power signal can represent the 4N states through M bits of information.

[0139] In Implementation 2, the low-power signal can use different sequence information to represent different values / levels of the PDB. For example, the overlaid sequence of the low-power signal can use a plurality of sequence information to send, and the plurality of sequence information respectively has a correlation relationship with different values / levels of the PDB. In this case, the value / level of the PDB of the first service is determined by the sequence information used by the overlaid sequence of the low-power signal and the correlation relationship between the plurality of sequence information and the different values / levels of the PDB. For another example, the sequence information used by the overlaid sequence of the low-power signal is a ZC sequence. In this case, different values / levels of the PDB can be indicated by different cyclic shifts or different root values of the ZC sequence.

[0140] In Implementation 3, the bit position of the bit information used to indicate the value / level of the PDB of the first service is located before the bit position of other bit information in the low-power signal. For example, the bit information used to indicate the value / level of the PDB of the first service is located at the beginning of all bit information in the low-power signal. Alternatively, the bit position of the bit information used to indicate the value / level of the PDB of the first service is located after the bit position of other bit information in the low-power signal. For example, the bit information used to indicate the value / level of the PDB of the first service is located at the end of all bit information in the low-power signal.

[0141] In another possible implementation 2 of the terminal acquiring the PDB of the first service, the terminal receives a first message from the network device, and the first message is used to determine the PDB of the first service. That is, the network device indicates the terminal whether to monitor the PDCCH through the low-power signal, and indicates the PDB of the first service through another message (denoted as the first message) different from the low-power signal.

[0142] Optionally, the first message includes RRCReconfiguration.

[0143] In the case that the network device indicates the PDB of the first service to the terminal through the first message different from the low-power signal, the reception position of the first message can be any of the following positions:

[0144] Position 1, the interval between the reception position of the first message and the start position of the measurement gap is T1, the T1 is a positive number, and the measurement gap is determined by the second message sent by the network device.

[0145] It needs to be understood that the terminal can receive the reference signal (such as SSB or CSI-RS) from the network device through the main receiver in each DRX cycle and perform channel quality measurement based on the reference signal. When the terminal performs gap-based intra-frequency measurement, the network device can configure the terminal with a measurement gap in each DRX cycle through the second message, and the terminal receives the reference signal from the network device through the main receiver in the measurement gap and performs channel quality measurement based on the reference signal.

[0146] In position 1, the reception position of the first message (or understood as the sending position of the network device sending the first message) is before the start position of the measurement gap, and the interval between the reception position of the first message and the start position of the measurement gap is T1, for example, as shown in (a) of FIG. 9.

[0147] Wherein, the specific value of T1 can be adjusted according to specific application scenarios, and the specific value of T1 is not limited in the present application. The specific value of T1 can be pre-defined by the protocol, or the network device can indicate the terminal through indication signaling, and the present application does not limit this.

[0148] Optionally, it can be agreed or pre-defined by the protocol that the terminal supporting the low-power signal (or understood as having LP-WUR) performs gap-based intra-frequency measurement in each DRX cycle.

[0149] Position 2, the interval between the reception position of the first message and the end position of the measurement gap is T2, and the T2 is a positive number.

[0150] In position 2, the reception position of the first message (or understood as the sending position of the network device sending the first message) is after the end position of the measurement gap, and the interval between the reception position of the first message and the end position of the measurement gap is T2, for example, as shown in (b) of FIG. 9.

[0151] The specific value of T2 can be adjusted according to a specific application scenario, and the specific value of T2 is not limited in the present application. The specific value of T2 can be pre-defined by a protocol, or can be indicated by the network device to the terminal through indication signaling, and the present application does not limit this.

[0152] Position 3, the receiving position of the first message is during the running of the first timer, the drx-onDurationTimer, the second timer or the drx-InactivityTimer.

[0153] It can be understood that the terminal starts the main receiver to monitor the PDCCH during the running of the first timer, the drx-onDurationTimer, the second timer or the drx-InactivityTimer. In this case, the terminal does not need to additionally start the main receiver to receive the first message, and can directly receive the first message in the case of starting the main receiver, which is beneficial to saving the terminal power consumption.

[0154] Position 4, the interval between the receiving position of the first message and the receiving position of the SSB is less than a third threshold, and the receiving position of the SSB is determined by the network device.

[0155] It should be understood that the terminal can receive the reference signal (such as SSB or CSI-RS) from the network device through the main receiver in each DRX cycle, and perform channel quality measurement based on the reference signal. When the terminal performs non-gap-based intra-frequency measurement, the network device indicates the receiving position of the reference signal to the terminal through the fourth indication information. Subsequently, the interval between the sending position (or understood as the receiving position of the terminal receiving the first message) of the network device sending the first message and the sending position (or understood as the receiving position of the terminal receiving the reference signal) of the network device sending the reference signal is less than the third threshold. By implementing this possible way, the first message and the reference signal for measurement have a correlation relationship, which is beneficial to the terminal to accurately receive the first message.

[0156] It should be stated that the indication information (including any one of the first indication information to the fifth indication information) mentioned in the present application can be carried in any message (i.e. any one of the first message to the fifth message) mentioned in the present application without logical conflict, and the whole text is as follows.

[0157] Position 5, the receiving position of the first message is during the feedback period of sending the CSI-RS.

[0158] It needs to be understood that after the terminal receives the reference signal (such as SSB or CSI-RS) from the network device through the main receiver in each DRX cycle and performs channel quality measurement based on the reference signal, the terminal sends measurement feedback to the network device. In this case, the sending position of the first message sent by the network device to the terminal (or understood as the receiving position of the first message received by the terminal) is during the feedback of the reference signal. By implementing this possible way, it is beneficial to avoid frequently turning on the main receiver of the terminal, thereby facilitating the terminal to accurately receive the first message.

[0159] Condition ②, the terminal receives first indication information including a first offset value, the first offset value being the interval between the start position of the first timer and the start position of the drx-onDurationTimer.

[0160] In condition ②, when the network device configures the drx-onDurationTimer for the terminal, when the network device configures the first offset value (for example, the network device sends the first indication information including the first offset value to the terminal), it is considered that the first condition is met, and the terminal and / or the network device starts the first timer.

[0161] Condition ③, the terminal receives first indication information including a first offset value, and the first offset value is not 0.

[0162] It can be understood that when the first offset value is 0, the start position of the first timer and the start position of the drx-onDurationTimer are the same. In condition ③, when the network device configures the drx-onDurationTimer for the terminal, when the network device configures the first offset value, and the first offset value is not 0, it is considered that the first condition is met, and the terminal and / or the network device starts the first timer.

[0163] Condition ④, the terminal receives second indication information including related parameters of the first timer. Wherein, the related parameters of the first timer include at least one of the following: the duration of the first timer, the length of the first timer, the start position of the first timer, or the interval between the start position of the first timer and the start position of the drx-onDurationTimer.

[0164] It needs to be understood that the terminal receiving the second indication information including the related parameters of the first timer can be considered that the network device configures the related parameters of the first timer, or understood as the network device configuring the first timer, or understood as the network device indicating the related parameters of the first timer to the terminal through the second indication information.

[0165] In condition IV, when the terminal receives the second indication information including the related parameters of the first timer, or the network device configures the related parameters of the first timer, it is considered that the first condition is met, and the terminal and / or the network device starts the first timer.

[0166] In a possible implementation, before the terminal determines whether to start the first timer according to the first condition (i.e., whether to start the first timer or start the drx-onDurationTimer), the network device indicates to the terminal whether the network device supports starting the first timer for PDCCH monitoring. In a possible implementation, the network device indicates whether the network device supports starting the first timer for PDCCH monitoring through the third message. In another possible implementation, the network device indicates that it supports starting the first timer for PDCCH monitoring through the third message only when the network device supports starting the first timer for PDCCH monitoring.

[0167] In a possible implementation, the terminal receives a fourth message for indicating to start the second timer, and the length of the second timer is a positive number. The fourth message includes third indication information indicating that the second timer is started when PDCCH is monitored during the running period of the first timer or the running period of the second timer. Alternatively, it is understood that the terminal receives the fourth message from the network device, and the fourth message indicates that the second timer can be started, and the starting time of the second timer is the time when PDCCH is monitored during the running period of the first timer or the running period of the second timer.

[0168] Optionally, FIG. 7 can also include optional steps S702A and S702B. In S702A, the second timer is started when the terminal monitors PDCCH during the running period of the first timer, the network device sends PDCCH during the running period of the second timer, and the terminal monitors PDCCH during the running period of the second timer. In S702B, the second timer is restarted when the terminal monitors PDCCH during the running period of the second timer, the network device sends PDCCH during the running period of the second timer, and the terminal monitors PDCCH during the running period of the second timer.

[0169] For example, FIG. 10 shows a schematic diagram of extending the time of monitoring PDCCH by the terminal and / or the network device through the second timer. In (a) of FIG. 10, the terminal monitors PDCCH at time T3 during the running of the first timer, and then the terminal starts the second timer at the time T3, i.e., the time T3 is the starting position of the second timer. In (b) of FIG. 10, the terminal monitors PDCCH again at time T4 during the running of the second timer after starting the second timer, and then the terminal restarts the second timer at the time T4, i.e., the time T4 is the starting position of the second timer.

[0170] It should be understood that the terminal and / or the network device can extend the time of monitoring PDCCH by starting or restarting the second timer. When the second timer can be started or restarted, the terminal and the network device can have a longer time to transmit the first service. When the second timer cannot be started or restarted, the terminal and the network device can only have a shorter time to transmit the first service.

[0171] In combination with the above understanding, the present application further provides an optional implementation. In a case that the terminal and the network device transmit the first service through a shorter time (denoted as a first case), the terminal and the network device transmit the first service with a modulation and coding strategy (MCS) from a first set of values. In a case that the terminal and the network device transmit the first service through a longer time (denoted as a second case), the terminal and the network device transmit the first service with the modulation and coding strategy (MCS) from a second set of values. The minimum value of the elements in the first set is greater than the maximum value of the elements in the second set.

[0172] For example, the first set is {0, 1, 2,..., 16}, and the second set is {17, 18, 19,..., 31}. The MCS of the terminal and the network device transmitting the first service in the first case is denoted as a first MCS, and the first MCS is one of the elements in the first set. The MCS of the terminal and the network device transmitting the first service in the second case is denoted as a second MCS, and the second MCS is one of the elements in the second set. The first MCS is greater than the second MCS.

[0173] That is, in the first case, the terminal and the network device transmit the service data of the first service with a larger MCS, which is beneficial to improve the transmission rate of the service data of the first service. In the second case, the terminal and the network device transmit the service data of the first service with a smaller MCS, which is beneficial to improve the transmission reliability of the service data of the first service.

[0174] The first case includes, but is not limited to, any one of the following cases: ①, a case where the terminal does not receive the fourth message; ②, a case where the terminal receives the fourth message, but the fourth message indicates that the length of the second timer is 0. The second case includes, but is not limited to, a case where the terminal receives the fourth message, and the fourth message indicates that the length of the second timer is not 0.

[0175] In one possible implementation of the terminal determining the length of the first timer and / or the length of the second timer, the terminal receives a fifth message from the network device, the fifth message being used to determine or indicate the length of the first timer and / or the length of the second timer. For example, the fifth message includes fifth indication information, the fifth indication information indicating that the length of the first timer is the length of the drx-onDurationTimer or the length of the drx-InactivityTimer configured by the network device, and the fifth indication information can also indicate that the length of the second timer is the length of the drx-onDurationTimer or the length of the drx-InactivityTimer configured by the network device.

[0176] In another possible implementation of the terminal determining the length of the first timer and / or the length of the second timer, the length of the first timer is predefined, or the length of the second timer is predefined. For example, the length of the first timer is predefined as a first time length in a communication protocol, and the length of the second timer is predefined as a second time length in the communication protocol. Alternatively, the length of the first timer is predefined as the length of the drx-onDurationTimer or the length of the drx-InactivityTimer configured by the network device, and the length of the second timer is predefined as the length of the drx-onDurationTimer or the length of the drx-InactivityTimer configured by the network device.

[0177] S703, if the first condition is not met, the terminal starts the drx-onDurationTimer, and monitors the PDCCH during the running of the drx-onDurationTimer.

[0178] Correspondingly, if the first condition is not met, the network device starts the drx-onDurationTimer, and sends the PDCCH during the running of the drx-onDurationTimer. The S703 is described below in combination with the description of the first condition in S702.

[0179] When the first condition includes condition ① in S702, in a case that the PDB of the first service is large (e.g., greater than or equal to a first threshold) and / or the interval between the first MO and the drx-onDurationTimer is small (e.g., less than or equal to a second threshold), it is considered that the first condition is not satisfied, and the terminal and / or the network device starts the drx-onDurationTimer.

[0180] When the first condition includes condition ② in S702, in a case that the terminal does not receive the first indication information including the first offset value, or it is understood that the network device does not configure the first offset value (e.g., the network device does not send the first indication information including the first offset value to the terminal), it is considered that the first condition is not satisfied, and the terminal and / or the network device starts the drx-onDurationTimer.

[0181] When the first condition includes condition ③ in S702, in a case that the terminal does not receive the first indication information including the first offset value, or receives the first indication information indicating that the first offset value is 0, or the network device does not configure the first offset value, or the network device configures the first offset value as 0, it is considered that the first condition is not satisfied, and the terminal and / or the network device starts the drx-onDurationTimer.

[0182] When the first condition includes condition ④ in S702, in a case that the terminal does not receive the second indication information including the related parameters of the first timer, or the network device does not configure the related parameters of the first timer, it is considered that the first condition is not satisfied, and the terminal and / or the network device starts the drx-onDurationTimer.

[0183] Optionally, in a case that the first timer is determined to be started according to the first condition, the terminal can not start the drx-onDurationTimer in the first DRX cycle. In a case that the drx-onDurationTimer is determined to be started according to the first condition, the terminal can not start the first timer in the first DRX cycle.

[0184] For example, in a case that the first timer is determined to be started according to the first condition, when the end position of the first timer and the start position of the drx-onDurationTimer overlap, or the end position of the second timer and the start position of the drx-onDurationTimer overlap, or the start position of the drx-onDurationTimer is earlier than the end position of the first timer, or the start position of the drx-onDurationTimer is earlier than the end position of the second timer, the drx-onDurationTimer does not need to be started after the first timer is started.

[0185] For another example, after starting the first timer according to the first condition, when the interval between the end position of the first timer and the start position of the drx-onDurationTimer is less than a certain threshold, or the interval between the end position of the second timer and the start position of the drx-onDurationTimer is less than a certain threshold, or there is no MO between the end position of the first timer and the start position of the drx-onDurationTimer, or there is no MO between the end position of the second timer and the start position of the drx-onDurationTimer, the drx-onDurationTimer is also started for PDCCH monitoring after the first timer is started.

[0186] For another example, after starting the first timer according to the first condition, when the interval between the end position of the first timer and the start position of the drx-onDurationTimer is greater than a certain threshold, or the interval between the end position of the second timer and the start position of the drx-onDurationTimer is greater than a certain threshold, the drx-onDurationTimer is stopped after the first timer is started.

[0187] For another example, after starting the first timer according to the first condition, when the interval between the end position of the first timer and the start position of the drx-onDurationTimer is greater than a certain threshold, or the interval between the end position of the second timer and the start position of the drx-onDurationTimer is greater than a certain threshold, or there is MO between the end position of the first timer and the start position of the drx-onDurationTimer, or there is MO between the end position of the second timer and the start position of the drx-onDurationTimer, the drx-onDurationTimer is stopped after the first timer is started.

[0188] In summary, the terminal and / or network device can monitor the PDCCH by starting different timers (i.e., the first timer and the drx-onDurationTimer), adjust the transmission delay of the first service and the power consumption of the terminal, which is conducive to reducing the transmission delay of service data, improving the efficiency of the terminal receiving service data, and also conducive to reducing the energy consumption of the terminal while meeting the transmission demand of service data.
