Communication method Technical Field

[0001] The present application relates to the field of wireless communications, and more particularly, to a communication method. Background Art

[0002] With the development of wireless communication systems, base stations and user equipment (UEs) support technologies such as large bandwidth and multiple antennas, which in turn increases their power consumption. Reducing the power consumption of base stations and user equipment has always been an important research direction in communication systems.

[0003] Summary of the Invention

[0004] In view of this, one aspect of an embodiment of the present application provides a communication method, which is performed by a user equipment including a first receiver and a second receiver, including: receiving first information, the first information including a first parameter of cell discontinuous transmission (Cell DTX) and a second parameter of a low power wake-up signal (LP-WUS), the first parameter including a period of Cell DTX, and the first information is received by the first receiver; determining a monitoring timing of the LP-WUS based on the second parameter; determining a monitoring behavior of the LP-WUS based on the first parameter and the monitoring timing, wherein the LP-WUS is at least used to indicate a behavior of monitoring PDCCH. Therefore, the UE and the base station can determine the monitoring behavior of the LP-WUS based on the parameters of Cell DTX and / or the parameters of C-DRX, as well as the monitoring timing of the LP-WUS, to ensure that the behavior on the UE side and the behavior on the base station side are consistent, thereby enabling normal communication between the base station and the UE.

[0005] Another aspect of an embodiment of the present application provides a communication method, performed by a user equipment, comprising: receiving first information, the first information including a first parameter of Cell DTX and / or a parameter of C-DRX, and the first information also including the length of one or more first timers; when a condition is met, starting or re-running the first timer, the first timer being used to activate or deactivate LP-WUS; and determining the behavior or length of the first timer based on the status of Cell DTX and / or the status of C-DRX. This can prevent the UE from frequently switching between the first receiver and the second receiver, which would otherwise cause additional delay in data transmission.

Therefore, the signal sent by the base station during the inactive time of Cell DTX can be reduced, thereby saving the power consumption of the base station. At the same time, the UE and the base station determine the monitoring behavior of LP-WUS based on the parameters of Cell DTX and / or the parameters of C-DRX, as well as the monitoring timing of LP-WUS, to ensure that the behavior on the UE side and the behavior on the base station side are consistent, thereby enabling normal communication between the base station and the UE.

[0008] Another aspect of an embodiment of the present application provides a communication method, performed by a base station, comprising: sending first information, the first information including first parameters of Cell DTX and / or parameters of C-DRX, and the first information also including the lengths of one or more first timers; starting or re-running the first timers when a condition is met, wherein the first timers are used to activate or deactivate LP-WUS; and determining the behavior or length of the first timers based on the status of Cell DTX and / or the status of C-DRX. Therefore, frequent switching of the UE between the first receiver and the second receiver, which would cause additional delay in data transmission, can be avoided.

[0009] Another aspect of an embodiment of the present application provides a communication method performed by a base station, the communication method comprising: transmitting first information, the first information including parameters of an LP-WUS, the LP-WUS parameters including a time domain location and / or a frequency domain location of an LP-WUS monitoring opportunity; and transmitting the LP-WUS, the LP-WUS carrying different functions using one or more of a TDM, FDM, and CDM method. Thus, the LP-WUS, with a limited number of bits, can carry more functions.

[0039] It should be understood that references to "embodiments" throughout this specification mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Therefore, various embodiments throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0040] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as Wireless Local Area Networks (WLAN), Wireless Fidelity (Wi-Fi) or other communication systems.

[0041] Figure 1 is a schematic diagram of the network architecture of a communication system. The communication system may include one or more user equipment (UE) 10 (Figure 1 shows only one) and one or more base stations (BS) 20 (Figure 1 shows only one). Figure 1 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solutions provided in the embodiments of the present application. Among them, UE 10 is connected to base station 20 in a wireless manner. It should be noted that Figure 1 is only schematic, and the embodiments of the present application do not limit the number of base stations 20 and UE 10 included in the communication system. In some embodiments, the communication system may also include other devices, such as wireless relay equipment, wireless backhaul equipment or core network.

[0042] A UE includes a device that provides voice and / or data connectivity to a user, and may include, for example, a handheld device with wireless connectivity or a processing device connected to a wireless modem. A UE may communicate with a core network via a base station, and may include a wireless UE, a mobile UE, a device-to-device (D2D) UE, a vehicle-to-everything (V2X) UE, a machine-to-machine / machine-type (M2M / MTC) UE, an Internet of Things (IoT) UE, a subscriber unit, a subscriber station, a mobile station, a remote station, an access point (AP), a remote UE, an access UE, a user UE, a user agent, or a terminal. A UE may include various UE devices, such as a mobile phone (also known as a "cellular" phone), a computer with a mobile UE, a portable, pocket-sized, handheld, or computer-embedded mobile device, and the like. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and other devices, as well as restricted devices (such as devices with low power consumption, or devices with limited storage capacity, or devices with limited computing power), are not restricted here.

[0043] It should be noted that the UE involved in the embodiments of the present application may include a main receiver (MR) and a secondary receiver. Compared with the main receiver, the secondary receiver consumes very little power when processing signals. The secondary receiver may also be called a low-power wake-up receiver (LP-WUR, denoted as LR). In existing New Radio (NR) systems, signals such as the Synchronization Signal Block (SSB), Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Channel State Information Reference Signal (CSI-RS), and Sounding Reference Signal (SRS) are generally considered to be processed through MR. Existing systems have very high requirements for time / frequency synchronization accuracy, as well as features such as large bandwidth and high throughput. Therefore, receivers require high-precision modules, which incur higher power consumption. For example, high-precision RF low-noise amplifiers, high-precision local oscillators, and high-sampling-rate analog-to-digital converters are required. The LR architecture can differ from the MR architecture. LR has lower requirements for time / frequency synchronization accuracy, smaller bandwidth, and lower data rates. Therefore, it can use lower-precision modules or simply remove some modules to reduce power consumption. Some LR modules can be shared with some MR modules, or some or all LR modules can be independent of MR modules. The LR receiver architecture can use RF envelope detection, IF envelope detection, or baseband envelope detection. The LR is primarily used to receive a wake-up signal, which can be called a low-power wake-up signal (LP-WUS). This LP-WUS is different from the wake-up signal on the primary receiver in the prior art. In the prior art, the wake-up signal on the primary receiver is carried on the PDCCH. Therefore, this wake-up signal on the primary receiver can also be called a PDCCH-based WUS. The UE needs to perform channel estimation, demodulation, decoding, and other operations to obtain the information carried by the PDCCH. LP-WUS and PDCCH-based WUS are two different signals.The power consumption required for the terminal to monitor LP-WUS is much lower than the power consumption required to monitor PDCCH based WUS. LR can also receive a synchronization signal, through which the UE can obtain coarse synchronization. This synchronization signal can be recorded as a low power synchronization signal (LP-SS). In order to save the power consumption of the UE, when there is no data transmission, the UE can receive LP-SS and / or LP-WUS through the LR, and the UE's MR can be in a sleep state, so that the UE can only turn on the modules required by the LR and turn off the MR's modules. When there is data transmission, the UE can wake up the MR according to the received LP-WUS, the UE turns on the MR's modules, and the UE transmits between the MR and the base station to ensure throughput.

[0044] A base station is an access device that a UE uses to access the mobile communication system wirelessly. A base station may be a radio access network (RAN). The RAN may include a new generation base station (gNB), an evolved node B (eNB), a next generation eNB (ng-eNB), wireless backhaul equipment, a radio network controller (RNC), a node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (HeNB or HNB), a baseband unit (BBU), a transmission and receiving point (TRP), a transmission point (TP), a mobile switching center, and the like in a 5G communication system, without limitation.

[0045] In the embodiments of the present application, the device used to implement RAN functions can be the RAN itself, or a device capable of supporting the RAN in implementing such functions, such as a chip system or a combination of devices or components capable of implementing base station functions, which can be installed in the RAN. In the embodiments of the present application, the chip system can be composed of a chip or can include a chip and other discrete components.

[0046] The following is an explanation of the relevant technical features involved in the embodiments of the present application. It should be noted that these explanations are intended to make the embodiments of the present application easier to understand and should not be regarded as limiting the scope of protection claimed by the present application.

[0047] 1. C-DRX (Connected-Discontinuous Reception)

[0048] In the Radio Resource Control (RRC) connected mode, a C-DRX mechanism is proposed. The C-DRX mechanism can enable the UE to sleep in certain time periods and not monitor the PDCCH, thereby saving the UE's power consumption.

[0049] The base station configures C-DRX parameters for the UE, including the C-DRX cycle (called a DRX cycle). A C-DRX cycle corresponds to a C-DRX active period and a C-DRX inactive period. During the active period, the UE needs to monitor the PDCCH; during the inactive period, the UE does not monitor the PDCCH to reduce power consumption, as shown in Figure 2.

[0050] The activation period of C-DRX includes the operation period of the duration timer (drx onDurationTimer). The UE can determine the start time of the duration timer according to the C-DRX cycle, and the UE periodically starts to run the duration timer. During the operation of the duration timer, the UE monitors the PDCCH. The activation period of C-DRX also includes the operation period of the inactivity timer (Drx InactivityTimer). The UE monitors the PDCCH during the activation period of C-DRX. When the UE receives the PDCCH, the PDCCH schedules the new transmission (Initial Transmission, or called initial transmission) data, and the UE starts or restarts the inactivity timer. The UE continues to monitor the PDCCH during the operation of the inactivity timer.

[0051] In addition, the C-DRX activation period also includes the downlink retransmission timer (drx-RetransmissionTimerDL) and the uplink retransmission timer (drx-RetransmissionTimerUL). The downlink retransmission timer indicates the maximum time to receive downlink retransmissions. The uplink retransmission timer indicates the maximum time to receive uplink retransmission schedules.

[0052] It should be noted that the PDCCH mentioned in the above C-DRX mechanism mainly refers to the PDCCH carrying at least one of the following DCI: Cell-Radio Network Temporary Identifier (RNTI), C-RNTI, Cancellation indication-RNTI (CI-RNTI), Configured Scheduling-RNTI (CS-RNTI), Interruption-RNTI (INT-RNTI), Slot Format Indication-RNTI (SFI-RNTI), Semi-Persistent Channel State Information (CSI)-RNTI, SP-CSI-RNTI, Transmit Power Control-Physical uplink control channel-RNTI (TPC-PUCCH-RNTI), Transmit Power Control-Physical uplink shared channel-RNTI (TPC-PUCCH-RNTI), Transmit Power Control-Physical uplink shared channel-RNTI channel-RNTI, TPC-PUSCH-RNTI), Transmit Power Control-Sounding Reference Signal-RNTI (TPC-SRS-RNTI), Availability indication-RNTI (AI-RNTI), Sidelink-Radio Network Temporary Identifier (Sidelink-RNTI, SL-RNTI), Sidelink Configured Scheduling-Radio Network Temporary Identifier (Sidelink Configured Scheduling-RNTI, SLCS-RNTI), Sidelink Semi-Persistent Scheduling V2X-Radio Network Temporary Identifier (Sidelink Semi-Persistent Scheduling V2X-RNTI, SL Semi-Persistent Scheduling V-RNTI) scrambled DCI.For some cell-common DCIs, such as RNTI-scrambled DCIs such as System Information-RNTI (SI-RNTI), Paging-RNTI (P-RNTI), and Temporary Cell-RNTI (TC-RNTI), they are not affected by C-DRX, that is, whether the UE monitors such DCI does not need to be restricted by the C-DRX activation period or the C-DRX inactivation period.

[0053] C-DRX parameters are configured according to the UE, that is, they can be different for different UEs. For example, the C-DRX cycle can be different for different UEs, and the starting position and running time of the duration timer can also be different.

[0054] The C-DRX parameters and their descriptions are shown in Table 1.

[0055] Table 1

[0056] 2.Cell DTX (Cell Discontinuous Transmission)

[0057] In order to save power consumption of base stations, 3GPP introduced the Cell DTX mechanism, that is, the base station performs downlink transmission with the UE only in a specific time period and does not perform downlink transmission in other time periods, so as to achieve energy saving of the base station.

[0058] It should be noted that Cell DTX and C-DRX are two different mechanisms.

[0059] Figure 3 is a schematic diagram of Cell DTX. The base station configures Cell DTX parameters for the UE. These parameters include the Cell DTX cycle, offset value, and / or activation timer length. To save base station power consumption, these parameters are typically the same for multiple UEs within a cell.

[0060] The time period corresponding to one cycle of Cell DTX may include an active period of Cell DTX and an inactive period of Cell DTX.

[0061] During the activation period (or ON period) of Cell DTX, the base station may send DCI for scheduling new transmission data (for example, DCI scrambled by C-RNTI, CS-RNTI or Modulation Coding Scheme-Cell-RNTI (MCS-C-RNTI) and scheduling new transmission data), DCI format 2_0 / 2_1 / 2_2 / 2_3 / 2_4 / 2_5 (i.e., DCI scrambled by SFI-RNTI, INT-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPC-SRS-RNTI, CI-RNTI, AI-RNTI), semi-persistently scheduled PDSCH, periodic CSI-RS for measuring RI, or semi-persistent CSI-RS for measuring RI. Accordingly, the UE needs to receive these signals during the activation period of Cell DTX. During the inactive period (or OFF period) of Cell DTX, the base station does not send the above signal to save power consumption of the base station; accordingly, the UE does not receive the corresponding signal.

[0062] It is understandable that the longer the Cell DTX inactive period, the longer the base station can sleep and the deeper the shutdown depth, achieving better energy conservation. On the other hand, if the base station is in the Cell DTX inactive period for a long time, once there is data to be transmitted, the base station cannot schedule data before entering the next Cell DTX active period, which increases service transmission latency.

[0063] The active period of Cell DTX can also be referred to as the duration of Cell DTX, which can be recorded as cellDRX-onDurationTimer. The inactive period of Cell DTX is the time in the Cell DTX cycle excluding the active period of Cell DTX. The present invention does not limit the names of the active period, inactive period, and active time timer of Cell DTX. It is understood that while the cellDRX-onDurationTimer is running, the base station and the UE are in the active period of Cell DTX. When the cellDRX-onDurationTimer expires, the base station and the UE enter the inactive period of Cell DTX.

[0064] The base station and the UE can determine the start time of the Cell DTX activation timer according to the Cell DTX parameters. The Cell DTX activation timer appears periodically.

[0065] When the Cell DTX mechanism and the C-DRX mechanism work at the same time, the activation period of Cell DTX and the activation period of C-DRX may partially overlap. When the UE is in the activation period of C-DRX and in the inactivation period of Cell DTX, the UE does not need to monitor the PDCCH used to schedule new data. As shown in Figure 4, the activation period and inactivation period of Cell DTX are the same for UE1 and UE2 in the cell, and the parameters of UE1's C-DRX are different from those of UE2's C-DRX. UE1 needs to monitor the PDCCH used to schedule new data in time periods T1 and T2, and UE2 needs to monitor the PDCCH used to schedule new data in time periods T3 and T4. That is, in the part where the activation period of C-DRX and the activation period of Cell DTX overlap, the UE monitors the PDCCH used to schedule new data.

[0066] For retransmission scheduling, when the Cell DTX mechanism and the C-DRX mechanism work at the same time, if the uplink retransmission timer or the downlink retransmission timer of C-DRX is running, then no matter what state the Cell DTX is in (the UE is in the inactive period of Cell DTX or in the active period of Cell DTX), the UE can also monitor the PDCCH.

[0067] 3.LP-WUS (Low Power-Wake Up Signal)

[0068] As mentioned above, the UE includes a main receiver and a low-power wake-up receiver. When there is no data transmission, the UE can listen for the low-power wake-up signal through the LR, while the MR can be in a sleep state, thereby saving UE power consumption. When data transmission is required, the UE can wake up the MR through the LR, and data transmission is carried out between the MR and the base station to ensure throughput.

[0069] The waveform of the LP-WUS can use on-off keying (OOK), amplitude shift keying (ASK), frequency shift keying (FSK), etc. The UE can process the LP-WUS using sequence detection. The LP-WUS can be used to instruct the UE to monitor the PDCCH. For example, to save UE power consumption, the UE stops monitoring the PDCCH. At this time, the UE can turn off the MR. The base station can send the LP-WUS to the UE. The UE receives the LP-WUS through the LR. The LP-WUS instructs the UE to monitor the PDCCH. The UE will then turn on the MR and resume monitoring the PDCCH.

[0070] There are two possible monitoring modes for LP-WUS. One is continuous monitoring. The LR needs to be in the on state all the time. In this monitoring mode, the UE has more opportunities to monitor the LP-WUS. Except for some special cases (for example, encountering uplink symbols, LP-WUS being deactivated, etc.), the UE needs to monitor the LP-WUS slot by slot or monitoring opportunity by monitoring opportunity. When the base station wants the UE to wake up the MR, it can notify the UE through the LP-WUS as soon as possible, which is beneficial to reducing the data transmission delay. The other is periodic monitoring. In this monitoring mode, the UE monitors the LP-WUS in part of the time period, and does not need to monitor the LP-WUS for a period of time. The LR can be turned off during the time period when the LP-WUS is not monitored, which is beneficial to saving the power consumption of the UE. Figure 5 shows a schematic diagram of the monitoring timing of LP-WUS in the continuous monitoring mode and the periodic monitoring mode. In the periodic monitoring mode, a monitoring period of LP-WUS can include one or more monitoring opportunities. The period between the start time of each listening period and the start time of the next adjacent listening period can be considered the LP-WUS cycle. The number of listening opportunities in a listening period of the LP-WUS is not limited to the four shown in Figure 5, and can be one, two, or another number. The embodiments of the present application are not limited to this. A listening opportunity can occupy some or all symbols in a time slot, or can occupy symbols of multiple time slots. The present invention does not limit the duration of the LP-WUS listening opportunity.

[0071] LP-WUS can also be activated and deactivated. When LP-WUS is activated, taking continuous monitoring of LP-WUS as an example, the UE monitors LP-WUS at the monitoring opportunity of LP-WUS, and taking periodic monitoring of LP-WUS as an example, the UE monitors LP-WUS at the monitoring opportunity within the monitoring period of LP-WUS. Conversely, when LP-WUS is deactivated, taking continuous monitoring of LP-WUS as an example, the UE does not monitor LP-WUS at the monitoring opportunity of LP-WUS, and taking periodic monitoring of LP-WUS as an example, the UE does not monitor LP-WUS at the monitoring opportunity within the monitoring period of LP-WUS. Taking Figure 5 as an example, when LP-WUS is activated, the UE monitors LP-WUS at the monitoring opportunity in the figure, and when LP-WUS is deactivated, the UE does not monitor LP-WUS at the monitoring opportunity in the figure. There are several ways to activate / deactivate LP-WUS:

[0072] - Mode 1: The base station sends RRC signaling to the UE to indicate activation or deactivation of LP-WUS.

[0073] - Mode 2: The base station instructs the UE to activate or deactivate LP-WUS through L1 or L2 control signaling. For example, when the MR is in the open state, the UE can monitor the PDCCH, and the base station can instruct the activation or deactivation of LP-WUS through the downlink control information (DCI) in the PDCCH. For another example, the base station can also instruct the activation or deactivation of LP-WUS through LP-SS. In one embodiment, the L2 signaling can be a Medium Access Control (MAC) control element (CE), and the MAC CE carries the indication information for activating or deactivating LP-WUS. The UE can activate or deactivate LP-WUS by receiving the MAC CE message through the MR.

[0074] - Mode 3: The UE activates or deactivates the LP-WUS based on a predefined rule or method. For example, the LP-WUS is activated or deactivated by a timer. The timer length can be configured by the base station to the UE.

[0075] It should be noted that in the present invention, "monitoring" can be described as "receiving" or "detecting." For example, the act of monitoring LP-WUS can also be described as receiving LP-WUS or detecting LP-WUS. The LP-WUS monitoring opportunity refers to the symbol position or time slot position of the LP-WUS monitored by the UE, which can also be referred to as a reception opportunity, a detection opportunity, etc., but the present invention is not limited to this term.

[0076] It should be noted that, in the present invention, "not monitoring" can also be described as "stop monitoring" or "skip monitoring." For example, the UE not monitoring the LP-WUS can be described as the UE stopping monitoring the LP-WUS. For another example, the UE not monitoring the PDCCH can be described as the UE stopping monitoring the PDCCH. Similarly, "not sending" can also be described as "stop sending" or "skip sending." "Not receiving" can also be described as "stop receiving" or "skip receiving."

[0077] When a UE is configured with the Cell DTX and / or C-DRX mechanism and the UE is configured with the LP-WUS function, in order to ensure that the base station and the UE have consistent understanding and thus enable normal communication between the base station and the UE, how the UE monitors the LP-WUS becomes an urgent issue that needs to be solved.

[0078] The communication method provided in the embodiments of the present application is described in detail below.

[0079] An embodiment of the present application provides a communication method, which includes step S10, step S20 and step S30. In step S10, the UE receives first information, where the first information includes parameters of cell discontinuous transmission (Cell DTX) (or referred to as first parameters) and / or parameters of connected discontinuous reception (C-DRX), as well as parameters of low power wake-up signal (LP-WUS) (or referred to as second parameters). The parameters of Cell DTX include the period of Cell DTX, and the parameters of C-DRX include the period of C-DRX. The first information is received by an MR (also referred to as a first receiver). Accordingly, the base station sends the first information.

[0080] In step S20, the UE determines the monitoring timing of the LP-WUS according to the LP-WUS parameters; accordingly, the base station can also determine the monitoring timing of the LP-WUS, that is, the base station can determine the monitoring timing of the UE to monitor the LP-WUS.

[0081] In step S30, the UE determines the LP-WUS monitoring behavior based on the Cell DTX parameters and / or C-DRX parameters, as well as the LP-WUS monitoring timing. Accordingly, the base station may also determine the LP-WUS monitoring behavior based on the Cell DTX parameters and / or C-DRX parameters, as well as the LP-WUS monitoring timing. That is, the base station may determine the UE's LP-WUS monitoring behavior.

[0082] Steps S20 and S30 may be performed simultaneously or in sequence, and the present invention is not limited thereto.

[0083] LP-WUS is at least used to instruct the UE to monitor the PDCCH. Specifically, LP-WUS can be used to instruct the UE to monitor the PDCCH or not at the next PDCCH monitoring opportunity. Alternatively, the function of LP-WUS can also be described as being used to instruct the UE whether to wake up the MR. When the UE wakes up the MR, the UE monitors the PDCCH. When the UE does not wake up the MR, the UE does not monitor the PDCCH. The DCI carried by the PDCCH can be at least one of the DCI scrambled by C-RNTI, CS-RNTI or MCS-C-RNTI, or can be at least one of the DCI scrambled by CI-RNTI, INT-RNTI, SFI-RNTI, SP-CSI-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI, TPC-SRS-RNTI, AI-RNTI, SL-RNTI, SLCS-RNTI, and SL Semi-Persistent Scheduling V-RNTI.

[0084] The UE may determine the behavior of the PDCCH based on the detection result of the LP-WUS. The UE may determine whether the UE monitors the PDCCH or not based on the different sequences of the detected LP-WUS bearer, for example, sequence 1 indicates that the UE monitors the PDCCH, and sequence 2 indicates that the UE does not monitor the PDCCH. Alternatively, the UE may determine whether the UE monitors the PDCCH or not based on the different values ​​of the detected LP-WUS bearer, for example, an LP-WUS value of A indicates that the UE monitors the PDCCH, and an LP-WUS value of B indicates that the UE does not monitor the PDCCH. Alternatively, the UE may determine whether the UE monitors the PDCCH or not based on whether the LP-WUS is detected, for example, if the UE detects the LP-WUS, it indicates that the UE monitors the PDCCH, and if the UE does not detect the LP-WUS, it indicates that the UE does not monitor the PDCCH.

[0085] The LP-WUS may be received by the LR (also referred to as a second receiver).

[0086] The parameters of C-DRX may include a C-DRX period, and the parameters of LP-WUS may include a time / frequency domain position of LP-WUS and / or a period of LP-WUS, etc.

[0087] The UE and the base station determine the LP-WUS monitoring behavior based on the Cell DTX parameters and / or C-DRX parameters and the LP-WUS monitoring timing to ensure that the UE-side behavior and the base station-side behavior are consistent, thereby enabling normal communication between the base station and the UE.

[0088] The communication method according to the embodiment of the present application can be executed not only by the UE, but also by the base station. Optionally, the communication method can be executed by a chip in the UE and a chip in the base station. Here, the base station includes a processor and a memory, the memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to execute the communication method according to the embodiment of the present application. The UE includes a processor and a memory, the memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to execute the communication method according to the embodiment of the present application. The following description will be taken as an example of the communication method executed by the UE.

[0089] Figure 6 is a schematic flow chart of a communication method according to an embodiment of the present application. The communication method in Figure 6 can be executed by the UE in Figure 1 . The communication method in the embodiment of the present application is applicable to the case where the Cell DTX mechanism, the C-DRX mechanism, or the Cell DTX mechanism and the C-DRX mechanism are operating simultaneously. These three cases will be described below.

[0090] 1. The UE is configured with Cell DTX but not C-DRX

[0091] The communication method provided in the embodiment of the present application includes step S10, step S20 and step S30.

[0092] In step S10, the UE receives first information, where the first information includes Cell DTX parameters and LP-WUS parameters, where the Cell DTX parameters include a Cell DTX period. The first information is received via the MR.

[0093] In one embodiment, the LP-WUS is at least used to instruct the UE to monitor the PDCCH. The LP-WUS is received by the LR.

[0094] In one embodiment, step S10 may include: the UE receives parameters of Cell DTX, the parameters of Cell DTX include a period, an offset value and / or the length of an activation time timer, etc.; the UE receives parameters of LP-WUS, the parameters of LP-WUS may include a time domain position and / or a frequency domain position of LP-WUS, etc. Optionally, the parameters of LP-WUS may also include a period of LP-WUS and / or a listening period of LP-WUS. The time period corresponding to a period of LP-WUS may include a listening period and a non-listening period of LP-WUS, that is, the non-listening time refers to a period in the period of LP-WUS other than the listening period. The embodiments of the present application do not limit the names of the listening period and the non-listening period of LP-WUS.

[0095] In one embodiment, the parameters of Cell DTX may be carried through Radio Resource Control (RRC) signaling.

[0096] In one embodiment, the LP-WUS parameters may be carried via RRC signaling. In one embodiment, the Cell DTX parameters and the LP-WUS parameters may be carried via the same RRC signaling or via different RRC signaling. The steps of receiving the Cell DTX parameters and receiving the LP-WUS parameters may be performed simultaneously or separately in various orders.

[0097] In one embodiment, the LP-WUS parameters may be carried by a System Information Block (SIB) message. In one example, step S10 may include: the UE receiving the LP-WUS parameters carried by the SIB message; and the UE receiving the Cell DTX parameters carried by RRC signaling.

[0098] The communication method provided in the embodiment of the present application further includes: the UE receiving LP-SS parameters, such as the time / frequency domain location of the LP-SS, etc. The LP-SS parameters can be carried via SIB messages or RRC signaling.

[0099] Step S20: The UE determines the monitoring timing of the LP-WUS according to the parameters of the LP-WUS.

[0100] In one embodiment, the UE determines one or more monitoring opportunities of the LP-WUS according to the received LP-WUS parameters.

[0101] In step S30, the UE determines the LP-WUS monitoring behavior according to the Cell DTX parameter and the LP-WUS monitoring timing.

[0102] In one embodiment, step S30 may include: when the LP-WUS monitoring opportunity is within the Cell DTX inactive period, the UE does not monitor the LP-WUS during the LP-WUS monitoring opportunity. Correspondingly, when the LP-WUS monitoring opportunity is within the Cell DTX inactive period, the base station does not send the LP-WUS during the LP-WUS monitoring opportunity.

[0103] In one embodiment, step S30 may include: when the LP-WUS monitoring opportunity is within the inactive period of Cell DTX, the UE monitoring the LP-WUS at the LP-WUS monitoring opportunity. Correspondingly, when the LP-WUS monitoring opportunity is within the inactive period of Cell DTX, the base station may send the LP-WUS at the LP-WUS monitoring opportunity.

[0104] The following describes the UE's monitoring behavior (monitoring LP-WUS and not monitoring LP-WUS) at the LP-WUS monitoring opportunity when the LP-WUS monitoring opportunity is within the Cell DTX inactive period.

[0105] First, some embodiments of the present application will be described. In these embodiments, when the LP-WUS monitoring opportunity is within the inactive period of Cell DTX, the UE does not monitor the LP-WUS during the LP-WUS monitoring opportunity.

[0106] For example, as described above, step S30 may include: when the LP-WUS listening opportunity falls within the Cell DTX inactive period, the UE does not monitor the LP-WUS during the LP-WUS listening opportunity. Accordingly, during the Cell DTX inactive period, the base station does not transmit the LP-WUS during the LP-WUS listening opportunity. This embodiment reduces the number of signals sent by the base station during the Cell DTX inactive period, thereby saving base station power consumption. The UE can also reduce received signals, saving terminal power consumption. Furthermore, by ensuring consistency between UE-side and base station-side behavior, normal communication between the base station and UE is possible.

[0107] In one embodiment, the UE does not monitor the LP-WUS during at least one LP-WUS monitoring opportunity during the Cell DTX inactive period. For example, the UE does not monitor the LP-WUS during some of the LP-WUS monitoring opportunities during the Cell DTX inactive period.

[0108] In one embodiment, in a continuous monitoring mode (e.g., as shown in FIG7 and FIG8 ) and a periodic monitoring mode (e.g., as shown in FIG9 ), when the LP-WUS monitoring opportunity is within the Cell DTX inactive period, the UE does not monitor the LP-WUS during the LP-WUS monitoring opportunity. This is described in detail below.

[0109] Figures 7 and 8 show schematic diagrams of Cell DTX and LP-WUS monitoring opportunities in a continuous monitoring mode according to an embodiment of the present application. In Figures 7 and 8, monitoring opportunities when LP-WUS is not monitored are indicated by dotted lines.

[0110] In one embodiment, as shown in FIG7 , in a continuous monitoring mode, when the LP-WUS monitoring opportunity is within the active period of Cell DTX, the UE monitors the LP-WUS during the LP-WUS monitoring opportunity. When the LP-WUS monitoring opportunity is within the inactive period of Cell DTX, the UE does not monitor the LP-WUS during the LP-WUS monitoring opportunity. Furthermore, the UE may monitor the LP-WUS during the active period of the next Cell DTX cycle. In one embodiment, the UE runs the Cell DTX activation timer. After the Cell DTX activation timer expires, the UE does not monitor the LP-WUS during the LP-WUS monitoring opportunity until the active period of the next Cell DTX cycle, at which point the UE may continue to monitor the LP-WUS. For another example, LP-WUS can also be enabled (or activated). When LP-WUS is enabled, when the listening opportunity of LP-WUS is within the activation period of Cell DTX, the UE listens to LP-WUS during the listening opportunity of LP-WUS. When the UE enters the inactive period of Cell DTX, the UE does not listen to LP-WUS during the listening opportunity of LP-WUS, as shown in Figure 8.

[0111] FIG9 is a schematic diagram showing the monitoring timing of Cell DTX and LP-WUS in a periodic monitoring mode according to an embodiment of the present application.

[0112] In one embodiment, step S30 may include: at least one listening opportunity within the listening period of the LP-WUS is included in the activation period of the Cell DTX. In one embodiment, at least one LP-WUS listening opportunity within the listening period of the LP-WUS is included in the activation period of the Cell DTX, wherein the LP-WUS listening opportunity is within the activation period of the Cell DTX, and the UE listens to the LP-WUS during the listening opportunity of the LP-WUS; the LP-WUS listening opportunity is within the inactive period of the Cell DTX, and the UE does not listen to the LP-WUS during the listening opportunity of the LP-WUS, as shown in Figure 9. Figure 9 schematically shows the relationship between the Cell DTX period and the listening period of the LP-WUS and the number of listening opportunities in the listening period, but the embodiments of the present application are not limited thereto.

[0113] In another embodiment, the LP-WUS listening opportunities within the LP-WUS listening period are all included in the activation period of Cell DTX, which can also be understood as the LP-WUS listening period being included in the activation period of Cell DTX. Therefore, the UE will not monitor the LP-WUS during the inactive period of Cell DTX. In this embodiment, the LP-WUS listening opportunities within the LP-WUS listening period are all included in the activation period of Cell DTX and the LP-WUS cycle is aligned with the Cell DTX cycle.

[0114] Next, some other embodiments of the present application will be described. In the other embodiments, when the LP-WUS monitoring opportunity is within the inactive period of Cell DTX, the UE monitors the LP-WUS at the LP-WUS monitoring opportunity.

[0115] For example, as described above, step S30 may include: when the LP-WUS monitoring opportunity is within the Cell DTX inactive period, the UE monitoring the LP-WUS during the LP-WUS monitoring opportunity. Correspondingly, during the Cell DTX inactive period, the base station may send the LP-WUS during the LP-WUS monitoring opportunity. Through this embodiment, the base station can further adjust the Cell DTX parameters or status through the LP-WUS during the Cell DTX inactive period, thereby improving the flexibility of the base station. Alternatively, the base station can control the UE's behavior of monitoring the PDCCH during the next Cell DTX active period through the LP-WUS, thereby saving terminal power consumption.

[0116] In one embodiment, regardless of whether the UE monitors the LP-WUS during the active period of Cell DTX, once the UE enters the inactive period of Cell DTX, the UE monitors the LP-WUS during the LP-WUS monitoring opportunity during the inactive period of Cell DTX. For example, the UE does not monitor the LP-WUS during the active period of Cell DTX (e.g., the LP-WUS is disabled), but when the UE enters the inactive period of Cell DTX, the UE monitors the LP-WUS during the LP-WUS monitoring opportunity during the inactive period of Cell DTX. For another example, the UE monitors the LP-WUS during the active period of Cell DTX (e.g., the LP-WUS is enabled), but when the UE enters the inactive period of Cell DTX, the UE continues to monitor the LP-WUS during the LP-WUS monitoring opportunity during the inactive period of Cell DTX. In one embodiment, if there is no data to be transmitted during the inactive period of Cell DTX, the UE can continue to monitor the LP-WUS during the active period of the next Cell DTX cycle without monitoring the PDCCH through the MR, thereby saving power consumption of the terminal. If there is data to be transmitted during the inactive period of Cell DTX, the base station can instruct the UE to resume PDCCH monitoring through LP-WUS. The UE can start monitoring PDCCH during the active period of the next Cell DTX cycle, so that the base station can schedule data for the UE. In one embodiment, the base station can also adjust the parameters of Cell DTX or enable / disable Cell DTX through LP-WUS. For example, the base station adjusts the parameters of Cell DTX or enables / disables Cell DTX through LP-WUS, thereby saving power consumption or reducing transmission delay. As shown in Figure 10, when there is a large amount of data to be transmitted between the base station and the UE, the base station instructs to disable Cell DTX through LP-WUS, then the Cell DTX mechanism will be disabled, that is, it can be considered that the UE is always active, and the UE can continue to monitor PDCCH until Cell DTX is enabled again and the UE enters the inactive period of Cell DTX.

[0117] In one embodiment, at least one LP-WUS listening opportunity within the LP-WUS listening period is included in the Cell DTX inactive period, and the LP-WUS is monitored during the at least one LP-WUS listening opportunity.

[0118] In one embodiment of the present application, the communication method further includes: the UE obtains a first offset Offset1 and / or a second offset Offset2; the UE determines the listening period of the LP-WUS based on the first offset Offset1 and / or the second offset Offset2, the first offset Offset1 is used to indicate the offset of the starting point of the listening period relative to the starting point of the activation time timer of the Cell DTX, and the second offset Offset2 is used to indicate the offset of the end time of the listening period relative to the starting point of the activation time timer of the Cell DTX. In one embodiment, the first offset Offset1 is sent by the base station to the UE, and the second offset Offset2 is sent by the base station to the UE or notified by the UE to the base station. The second offset Offset2 may be related to the UE capability. Specifically, the UE may report the second offset Offset2 to the base station through UE capability signaling.

[0119] As shown in Figure 11, at least one LP-WUS listening opportunity within the LP-WUS listening period is included in the Cell DTX inactive period, and the LP-WUS is monitored during the at least one LP-WUS listening opportunity. Exemplarily, the UE obtains Cell DTX parameters, a first offset Offset1, and LP-WUS parameters, and may also obtain a second offset Offset2. The UE determines the LP-WUS listening opportunity based on the LP-WUS parameters. The LP-WUS listening period is determined based on the Cell DTX parameters, the first offset Offset1, the second offset Offset2, and the LP-WUS parameters, where the first offset indicates the offset of the listening period start point relative to the Cell DTX activation timer start point, and the second offset indicates the offset of the listening period end point relative to the Cell DTX activation timer start point. The LP-WUS listening opportunity within the LP-WUS listening period is within the Cell DTX inactive period, and the UE monitors the LP-WUS during the LP-WUS listening opportunity. The embodiments of the present application are not limited thereto. FIG11 schematically shows the relationship between the Cell DTX cycle and the LP-WUS monitoring period.

[0120] In one embodiment, the communication method according to the embodiments of the present application may also be performed by a base station by performing the following steps: the base station transmits the first information, the first information including Cell DTX parameters and LP-WUS parameters, the Cell DTX parameters including the Cell DTX period; the base station determines the LP-WUS monitoring timing; and the base station determines the UE's behavior of monitoring the LP-WUS based on the Cell DTX parameters and the LP-WUS monitoring timing. The communication method performed by the base station may be similar to the communication method in the above embodiment, and therefore, will not be repeated here.

[0121] The above describes in detail the communication method of LP-WUS under the Cell DTX mechanism. The above communication method and its variations of the embodiment of the present application are also applicable to the C-DRX mechanism.

[0122] 2. The UE is configured with C-DRX but not Cell DTX

[0123] In one embodiment, the communication method includes: a UE receiving first information, the first information including C-DRX parameters and LP-WUS parameters, the C-DRX parameters including a C-DRX cycle; the UE determining an LP-WUS monitoring timing based on the LP-WUS parameters; and the UE determining an LP-WUS monitoring behavior based on the C-DRX parameters and the LP-WUS monitoring timing. The first information is received via an MR.

[0124] In one embodiment, the LP-WUS is at least used to instruct the UE to monitor the PDCCH. The LP-WUS is received by the LR.

[0125] In one embodiment, the step of receiving the first information may include: the UE receives C-DRX parameters, the C-DRX parameters include a period, an offset value and / or a duration timer length, etc.; the UE receives LP-WUS parameters, the LP-WUS parameters may include a time domain position and / or a frequency domain position of the LP-WUS, etc. Optionally, the LP-WUS parameters may also include the LP-WUS period and / or the LP-WUS listening period. The time period corresponding to a period of the LP-WUS may include the LP-WUS listening period and the non-listening period, that is, the non-listening time refers to the period in the LP-WUS period other than the listening period. The embodiments of the present application do not limit the names of the LP-WUS listening period and the non-listening period.

[0126] In one embodiment, C-DRX parameters may be carried through RRC signaling.

[0127] In one embodiment, the LP-WUS parameters may be carried via RRC signaling. In one embodiment, the C-DRX parameters and the LP-WUS parameters may be carried via the same RRC signaling or via different RRC signaling. The steps of receiving the C-DRX parameters and receiving the LP-WUS parameters may be performed simultaneously or separately in various orders.

[0128] In one embodiment, the LP-WUS parameters may be carried by a SIB message. In one example, the step of receiving the first information may include: the UE receiving the LP-WUS parameters carried by the SIB message; and the UE receiving the C-DRX parameters carried by RRC signaling.

[0129] The method provided in the embodiment of the present application further includes: the UE receiving LP-SS parameters, such as the time / frequency domain position of the LP-SS, etc. The LP-SS parameters may be carried via SIB messages or RRC signaling.

[0130] In one embodiment, the UE determines one or more monitoring opportunities of the LP-WUS according to the received LP-WUS parameters.

[0131] In one embodiment, the LP-WUS monitoring behavior is determined based on C-DRX parameters and the LP-WUS monitoring opportunity. Specifically, when the LP-WUS monitoring opportunity is within a C-DRX inactive period, the UE does not monitor the LP-WUS during the LP-WUS monitoring opportunity. Correspondingly, when the LP-WUS monitoring opportunity is within a C-DRX inactive period, the base station does not send the LP-WUS during the LP-WUS monitoring opportunity.

[0132] In one embodiment, determining the LP-WUS monitoring behavior based on C-DRX parameters and the LP-WUS monitoring opportunity may specifically include: when the LP-WUS monitoring opportunity is within the C-DRX inactive period, the UE monitors the LP-WUS during the LP-WUS monitoring opportunity. Correspondingly, when the LP-WUS monitoring opportunity is within the C-DRX inactive period, the base station does not send the LP-WUS during the LP-WUS monitoring opportunity.

[0133] The following describes the UE's monitoring behaviors (monitoring LP-WUS and not monitoring LP-WUS) at the LP-WUS monitoring opportunity when the LP-WUS monitoring opportunity is within the C-DRX inactive period.

[0134] First, the following embodiments will be described as examples. In these embodiments, when the LP-WUS monitoring opportunity is within the C-DRX inactive period, the UE does not monitor the LP-WUS at the LP-WUS monitoring opportunity.

[0135] For example, as described above, the step of determining the LP-WUS monitoring behavior based on the C-DRX parameters and the LP-WUS monitoring timing may include: when the LP-WUS monitoring timing is within the C-DRX inactive period, the UE does not monitor the LP-WUS during the LP-WUS monitoring timing. Correspondingly, during the C-DRX inactive period, the base station does not send the LP-WUS during the LP-WUS monitoring timing. Through this embodiment, the UE can reduce the received signals and save the power consumption of the terminal. The base station can reduce the signals sent during the C-DRX inactive time, thereby saving the power consumption of the base station. At the same time, by ensuring that the UE-side behavior and the base station-side behavior are consistent, normal communication can be achieved between the base station and the UE.

[0136] In one embodiment, the UE does not monitor the LP-WUS during at least one LP-WUS monitoring opportunity during the C-DRX inactive period. For example, the UE does not monitor the LP-WUS during some of the LP-WUS monitoring opportunities during the C-DRX inactive period.

[0137] In one embodiment, in a continuous monitoring mode or a periodic monitoring mode, when the LP-WUS monitoring opportunity is within a C-DRX inactive period, the UE does not monitor the LP-WUS during the LP-WUS monitoring opportunity.

[0138] In one embodiment, when the LP-WUS monitoring opportunity is within the active period of C-DRX, the UE monitors the LP-WUS at the LP-WUS monitoring opportunity; when the LP-WUS monitoring opportunity is within the inactive period of C-DRX, the UE does not monitor the LP-WUS at the LP-WUS monitoring opportunity. Furthermore, the UE may monitor the LP-WUS during the active period of the next C-DRX cycle. In one embodiment, the UE runs at least one of a C-DRX duration timer, a C-DRX inactivity timer (drx-InactivityTimer), a C-DRX downlink retransmission timer (drx-RetransmissionTimerDL), or a C-DRX uplink retransmission timer (drx-HARQ-RTT-TimerUL); after at least one of these timers expires or after all of these timers expire, the UE does not monitor the LP-WUS at the LP-WUS monitoring opportunity until the active period of the next C-DRX cycle, at which point the UE may continue to monitor the LP-WUS. For another example, LP-WUS may be enabled (or activated). When LP-WUS is enabled, when the monitoring opportunity of LP-WUS is within the activation period of C-DRX, the UE monitors LP-WUS at the monitoring opportunity of LP-WUS. After LP-WUS is enabled within the activation period of C-DRX, the UE starts monitoring LP-WUS. When the UE enters the inactive period of C-DRX, the UE does not monitor LP-WUS at the monitoring opportunity of LP-WUS. The above embodiment may be applicable to a continuous monitoring mode.

[0139] In one embodiment, the step of determining the monitoring behavior of the LP-WUS according to the C-DRX parameters and the monitoring opportunity of the LP-WUS may include: at least one monitoring opportunity within the monitoring period of the LP-WUS is included in the activation period of the C-DRX.

[0140] In one embodiment, at least one LP-WUS monitoring opportunity within the LP-WUS monitoring period is included in the C-DRX activation period, wherein, when the LP-WUS monitoring opportunity is within the C-DRX activation period, the UE monitors the LP-WUS at the LP-WUS monitoring opportunity; when the LP-WUS monitoring opportunity is within the C-DRX inactive period, the UE does not monitor the LP-WUS at the LP-WUS monitoring opportunity.

[0141] In one embodiment, all LP-WUS monitoring opportunities within the LP-WUS monitoring period are included in the C-DRX activation period. Therefore, the UE does not monitor the LP-WUS during the C-DRX inactivity period. In this embodiment, all LP-WUS monitoring opportunities within the LP-WUS monitoring period are included in the C-DRX activation period, and the LP-WUS cycle is aligned with the C-DRX cycle.

[0142] Next, some other embodiments will be described as examples. In these embodiments, when the LP-WUS monitoring opportunity is within the C-DRX inactive period, the UE monitors the LP-WUS at the LP-WUS monitoring opportunity.

[0143] For example, as described above, the step of determining the LP-WUS monitoring behavior based on the C-DRX parameters and the LP-WUS monitoring timing may include: when the LP-WUS monitoring timing is within the C-DRX non-activation period, the UE monitors the LP-WUS during the LP-WUS monitoring timing. Accordingly, during the C-DRX non-activation period, the base station may send the LP-WUS during the LP-WUS monitoring timing. Through this embodiment, the base station may further adjust the C-DRX parameters or status through the LP-WUS during the C-DRX non-activation period, thereby improving the flexibility of the base station, or the base station may control the UE's behavior of monitoring the PDCCH during the next C-DRX activation period through the LP-WUS, thereby saving power consumption of the terminal.

[0144] In one embodiment, regardless of whether the UE monitors the LP-WUS during the active period of C-DRX, once the UE enters the inactive period of C-DRX, the UE monitors the LP-WUS during the LP-WUS monitoring opportunity during the inactive period of C-DRX. For example, the UE does not monitor the LP-WUS during the active period of C-DRX (e.g., the LP-WUS is disabled), but when the UE enters the inactive period of C-DRX, the UE monitors the LP-WUS during the LP-WUS monitoring opportunity during the inactive period of C-DRX. For another example, the UE monitors the LP-WUS during the active period of C-DRX (e.g., the LP-WUS is enabled), but when the UE enters the inactive period of C-DRX, the UE continues to monitor the LP-WUS during the LP-WUS monitoring opportunity during the inactive period of C-DRX. In one embodiment, if there is no data to be transmitted during the inactive period of C-DRX, the UE can continue to monitor the LP-WUS during the active period of the next C-DRX cycle without monitoring the PDCCH through the MR, thereby saving power consumption of the terminal. If there is data to be transmitted during the inactive period of C-DRX, the base station can instruct the UE to resume PDCCH monitoring through LP-WUS. The UE can then begin monitoring the PDCCH during the active period of the next C-DRX cycle, allowing the base station to schedule data for the UE. In one embodiment, the base station can also adjust C-DRX parameters or enable / disable C-DRX through LP-WUS. For example, the base station can adjust C-DRX parameters through LP-WUS to save power or reduce transmission latency.

[0145] In one embodiment, at least one LP-WUS listening opportunity within the LP-WUS listening period is included in a C-DRX inactive period, and the LP-WUS is monitored during the at least one LP-WUS listening opportunity.

[0146] The communication method provided by an embodiment of the present application also includes: the UE obtains a first offset Offset1 and / or a second offset Offset2; the UE determines the listening period of the LP-WUS based on the first offset Offset1 and / or the second offset Offset2, the first offset Offset1 is used to indicate the offset of the starting point of the listening period relative to the starting point of the C-DRX duration timer, and the second offset Offset2 is used to indicate the offset of the end time of the listening period relative to the starting point of the C-DRX duration timer. In one embodiment, the first offset Offset1 is sent by the base station to the UE, and the second offset Offset2 is sent by the base station to the UE or notified by the UE to the base station. The second offset Offset2 may be related to the UE capability. Specifically, the UE may report the second offset Offset2 to the base station through UE capability signaling.

[0147] At least one LP-WUS listening opportunity within the LP-WUS listening period is included in the C-DRX inactive period, and the UE monitors the LP-WUS during the at least one LP-WUS listening opportunity. Exemplarily, the UE obtains C-DRX parameters, a first offset Offset1, and LP-WUS parameters, and may also obtain a second offset Offset2; the UE determines the LP-WUS listening opportunity based on the LP-WUS parameters; and the LP-WUS listening period is determined based on the C-DRX parameters, the first offset Offset1, the second offset Offset2, and the LP-WUS parameters, where the first offset indicates an offset between a start point of the listening period and a start point of a C-DRX duration timer, and the second offset indicates an offset between an end point of the listening period and a start point of the C-DRX duration timer. The LP-WUS listening opportunity within the LP-WUS listening period is included in the C-DRX inactive period, and the UE monitors the LP-WUS during the LP-WUS listening opportunity.

[0148] In one embodiment, the communication method according to the embodiments of the present application may also be performed by a base station by the following steps: the base station transmits the first information, the first information including C-DRX parameters and LP-WUS parameters, the C-DRX parameters including the C-DRX cycle; the base station determines the LP-WUS monitoring timing; and the base station determines the UE's behavior for monitoring the LP-WUS based on the C-DRX parameters and the LP-WUS monitoring timing. The communication method performed by the base station may be similar to the communication method in the above-described embodiments, and therefore, will not be described again here. In one embodiment, the communication method according to the embodiments of the present application may be performed by a chip in a UE or a chip in a base station. Here, the base station includes a processor and a memory, the memory being configured to store a computer program, the processor being configured to call and execute the computer program stored in the memory to perform the communication method according to the embodiments of the present application. The UE includes a processor and a memory, the memory being configured to store a computer program, the processor being configured to call and execute the computer program stored in the memory to perform the communication method according to the embodiments of the present application. The communication method under the Cell DTX mechanism according to the above-described embodiments may also be applied to the C-DRX mechanism. A repeated description will not be given here.

[0149] 3. The UE is configured with C-DRX and Cell DTX

[0150] In the embodiments of the present application, the above communication method is also applicable to the case where the C-DRX mechanism and the Cell DTX mechanism operate simultaneously. A detailed description is provided below. Part of the description of the communication method under the Cell DTX mechanism is also applicable to this case, and will not be repeated here.

[0151] According to an embodiment of the present application, a communication method includes: a UE receiving first information, the first information including C-DRX parameters, Cell DTX parameters, and LP-WUS parameters, wherein the C-DRX parameters include a C-DRX cycle, and the Cell DTX parameters include a Cell DTX cycle. The first information is received via an MR. Accordingly, a base station transmits the first information. The UE determines an LP-WUS monitoring timing based on the LP-WUS parameters, and the base station can also determine the LP-WUS monitoring timing accordingly. Furthermore, the UE determines an LP-WUS monitoring behavior based on the C-DRX parameters, Cell DTX parameters, and the LP-WUS monitoring timing. The UE does not monitor the LP-WUS during monitoring timings within a specific time period, thereby reducing UE power consumption. Accordingly, the base station can also determine the UE's LP-WUS monitoring behavior based on the Cell DTX parameters, C-DRX parameters, and the LP-WUS monitoring timing. The following description uses a communication method performed by a UE as an example. Those skilled in the art can understand the communication method performed by the base station based on the communication method performed by the UE. A detailed description will not be given here.

[0152] In one embodiment, when the C-DRX mechanism and the Cell DTX mechanism operate simultaneously, the C-DRX parameters and the Cell DTX parameters can be carried separately via RRC signaling. The Cell DTX parameters and the Cell DTX parameters can be carried via the same RRC signaling or via different RRC signaling. The Cell DTX parameters, the C-DRX parameters, and the LP-WUS parameters can also be carried via the same RRC signaling or via different RRC signaling. Receiving the C-DRX parameters, receiving the Cell DTX parameters, and receiving the LP-WUS parameters can be performed simultaneously or separately in various orders. The LP-WUS parameters can also be carried via a SIB message. The UE can receive the LP-WUS parameters carried by the SIB message, and the UE can receive the Cell DTX parameters and C-DRX parameters carried by RRC signaling. The embodiments of the present application are not limited to the methods for configuring the Cell DTX parameters, the Cell DTX parameters, and the LP-WUS parameters.

[0153] When the C-DRX mechanism and the Cell DTX mechanism operate simultaneously, the activation period of the Cell DTX and the activation period of the C-DRX may not completely overlap.

[0154] In one embodiment, when the listening opportunity of the LP-WUS is in the active period of Cell DTX and in the inactive period of C-DRX, at least one of the listening opportunities monitors the LP-WUS; when the listening opportunity of the LP-WUS is in the active period of Cell DTX and in the active period of C-DRX, at least one of the listening opportunities monitors the LP-WUS; when the listening opportunity of the LP-WUS is in the inactive period of Cell DTX and in the active period of C-DRX, at least one of the listening opportunities does not monitor the LP-WUS; and / or when the listening opportunity of the LP-WUS is in the inactive period of Cell DTX and in the inactive period of C-DRX, at least one of the listening opportunities does not monitor the LP-WUS. In one embodiment, the C-DRX mechanism and the Cell DTX mechanism operate simultaneously, and the UE determines whether to monitor the LP-WUS based on whether the listening opportunity of the LP-WUS is in the active period of Cell DTX.

[0155] When C-DRX and Cell DTX operate simultaneously, the UE can be in at least one of the following four periods: Period A, Period B, Period C, and Period D, as shown in Figure 12. The C-DRX and Cell DTX states and UE behavior during these four periods are shown in Table 2.

[0156] Table 2

[0157] With reference to Table 2 and FIG12 , the step of determining the LP-WUS monitoring behavior based on the C-DRX parameters, the Cell DTX parameters, and the LP-WUS monitoring timing includes: monitoring the LP-WUS during time period A, i.e., when the LP-WUS monitoring timing is in the Cell DTX activation period and the C-DRX activation period; not monitoring the LP-WUS during time period B, i.e., when the monitoring timing is in the Cell DTX inactivation period and the C-DRX activation period; not monitoring the LP-WUS during time period C, i.e., when the monitoring timing is in the Cell DTX inactivation period and the C-DRX inactivation period, not monitoring the LP-WUS during time period C; and monitoring the LP-WUS during time period D, i.e., when the monitoring timing is in the Cell DTX activation period and the C-DRX inactivation period, monitoring the LP-WUS during time period D. FIG12 schematically illustrates the Cell DTX cycle and the C-DRX cycle, and their relationship with the LP-WUS monitoring timing, but the embodiments of the present application are not limited thereto. In addition, the present invention provides several embodiments of communication methods executed by a UE. As described above, those skilled in the art can derive corresponding communication methods executed by a base station based on the above embodiments. Based on the embodiments of the present application, the base station can reduce the number of signals sent during the inactive period of Cell DTX, thereby saving base station power consumption. The UE can also reduce the number of received signals, saving UE power consumption. Furthermore, by ensuring that the UE's behavior is consistent with that of the base station, normal communication between the base station and the UE is possible.

[0158] In one embodiment, when the C-DRX mechanism and the Cell DTX mechanism operate simultaneously, the communication method according to the embodiment of the present application further includes: receiving an LP-WUS, wherein the LP-WUS is also used to adjust the activation period of the C-DRX. For example, the LP-WUS instructs the UE to start the C-DRX duration timer (e.g., drx-onDurationTimer) in advance. For another example, the LP-WUS instructs the UE to increase the activation period of the C-DRX. As shown in Figure 13, the communication method according to the embodiment of the present application further includes: receiving an LP-WUS; and adjusting the time period E to the activation period of the C-DRX according to the LP-WUS. Specifically, the starting point of the C-DRX duration timer (e.g., drx-onDurationTimer) can be advanced, or a period of time after the LP-WUS can be adjusted to the activation period of the C-DRX. Figure 13 schematically shows the Cell DTX period, the C-DRX period, and their relationship with the monitoring timing of the LP-WUS, but the embodiments of the present application are not limited thereto. In FIG13 , the time position of receiving the LP-WUS and the time period E is merely a schematic diagram. In fact, there is a time interval between the time position of receiving the LP-WUS and the start time position of the time period E. The embodiments of the present application do not limit this.

[0159] In one embodiment, determining the LP-WUS monitoring behavior based on C-DRX parameters, Cell DTX parameters, and the LP-WUS monitoring timing includes: the UE monitoring the LP-WUS during the inactive period of Cell DTX. In one embodiment, referring to FIG13 , the UE monitors the LP-WUS during periods A, B, C, and D. Correspondingly, the base station can send the LP-WUS during the inactive period of Cell DTX. Therefore, the UE and the base station determine the LP-WUS monitoring behavior based on the C-DRX parameters, Cell DTX parameters, and the LP-WUS monitoring timing, thereby ensuring that the base station and the UE have consistent understanding, thereby enabling normal communication between the base station and the UE.

[0160] In one embodiment, the C-DRX mechanism and the Cell DTX mechanism operate simultaneously, and the UE determines whether to monitor the LP-WUS based on whether the LP-WUS monitoring opportunity is within the C-DRX active period. In one embodiment, when the LP-WUS monitoring opportunity is within the Cell DTX active period and the C-DRX inactive period, at least one of the monitoring opportunities does not monitor the LP-WUS; when the LP-WUS monitoring opportunity is within the Cell DTX active period and the C-DRX active period, at least one of the monitoring opportunities monitors the LP-WUS; when the LP-WUS monitoring opportunity is within the Cell DTX inactive period and the C-DRX active period, at least one of the monitoring opportunities monitors the LP-WUS; and / or when the LP-WUS monitoring opportunity is within the Cell DTX inactive period and the C-DRX inactive period, at least one of the monitoring opportunities does not monitor the LP-WUS. The UE can also reduce received signals, saving UE power consumption. Furthermore, by ensuring consistency between UE-side behavior and base station-side behavior, normal communication between the base station and the UE is possible. In one embodiment, the UE monitors the LP-WUS during the C-DRX inactive period, thereby ensuring that the base station and the UE have consistent understandings, thereby enabling normal communication between the base station and the UE.

[0161] In one embodiment, the UE monitors the LP-WUS before the duration timer (drx-onDurationTimer), as shown in Figure 14, which can be understood as the UE periodically monitoring the LP-WUS. In this case, the communication method according to the embodiment of the present application also includes: before determining the monitoring behavior of the LP-WUS according to the parameters of the C-DRX, the parameters of the Cell DTX and the monitoring timing of the LP-WUS, obtaining a first offset Offset1 and / or a second offset Offset2; determining the monitoring period of the LP-WUS based on the first offset Offset1 and / or the second offset Offset2, the first offset Offset1 is used to indicate the offset of the starting point of the monitoring period relative to the starting point of the C-DRX duration timer, and the second offset Offset2 is used to indicate the offset of the end time of the monitoring period relative to the starting point of the C-DRX duration timer. In one embodiment, the first offset Offset1 is sent by the base station to the UE, and the second offset Offset2 is sent by the base station to the UE or notified by the UE to the base station. FIG14 schematically shows the relationship between the Cell DTX cycle, the C-DRX cycle and the monitoring period of the LP-WUS, as well as the number of monitoring opportunities in the monitoring period, but the embodiments of the present application are not limited thereto.

[0162] For example, after obtaining the first offset Offset1 and / or the second offset Offset2, the step of determining the LP-WUS listening behavior based on the C-DRX parameters, the Cell DTX parameters, and the LP-WUS listening timing includes: monitoring the LP-WUS at the listening timing within the listening period, regardless of whether the LP-WUS listening timing is within the active period or the inactive period of the Cell DTX. In an exemplary embodiment, as shown in FIG14 , within the LP-WUS listening period, although some LP-WUS listening timings are within the active period of the Cell DTX and some LP-WUS listening timings are within the inactive period of the Cell DTX, the UE monitors the LP-WUS at all LP-WUS listening timings within the LP-WUS listening period. In the embodiments of the present application, the number of listening timings included in each listening period is not limited thereto and may be one, two, or four or more.

[0163] For example, after obtaining the first offset Offset1 and / or the second offset Offset2, the step of determining the LP-WUS monitoring behavior based on the C-DRX parameters, the Cell DTX parameters, and the LP-WUS monitoring timing includes: monitoring the LP-WUS at monitoring timings within the monitoring period and within the Cell DTX activation period. In an exemplary embodiment, as shown in FIG14 , within each LP-WUS monitoring period, some LP-WUS monitoring timings are within the Cell DTX activation period, and some LP-WUS monitoring timings are within the Cell DTX inactivity period. The UE does not monitor the LP-WUS at the monitoring timings within the Cell DTX inactivity period, and monitors the LP-WUS at the monitoring timings within the Cell DTX activation period. The UE monitors the LP-WUS at the monitoring timings within the Cell DTX activation period. In the embodiments of the present application, the number of monitoring timings included in each monitoring period is not limited thereto and may be one, two, or more than four.

[0164] In one embodiment, the UE monitors the LP-WUS before the activation period of the Cell DTX, as shown in FIG15 , which can be understood as the UE periodically monitoring the LP-WUS. In this case, the communication method according to the embodiment of the present application further includes: obtaining a first offset Offset1 and / or a second offset Offset2 before determining the monitoring behavior of the LP-WUS according to the parameters of the C-DRX, the parameters of the Cell DTX, and the monitoring timing of the LP-WUS; the UE determines the monitoring period of the LP-WUS based on the first offset Offset1 and / or the second offset Offset2, the first offset Offset1 being used to indicate the offset of the starting point of the monitoring period relative to the starting point of the activation time timer of the Cell DTX, and the second offset Offset2 being used to indicate the offset of the end time of the monitoring period relative to the starting point of the activation time timer of the Cell DTX. In one embodiment, the first offset Offset1 is sent by the base station to the UE, and the second offset Offset2 is sent by the base station to the UE or notified by the UE to the base station.

[0165] In addition, the communication method according to an embodiment of the present application further includes: receiving an LP-WUS, wherein the LP-WUS is also used to adjust the next activation period of the C-DRX. In one embodiment, the communication method according to an embodiment of the present application further includes: receiving an LP-WUS; according to the LP-WUS, starting the duration timer of the C-DRX (e.g., drx-onDurationTimer) in advance or increasing the activation period of the C-DRX. For example, the starting point of the duration timer of the C-DRX (e.g., drx-onDurationTimer) is advanced or the activation period of the C-DRX is increased before the next activation period.

[0166] In one embodiment, the UE monitors the LP-WUS during the activation period of Cell DTX, as shown in FIG16 , which can be understood as the UE periodically monitoring the LP-WUS. In this case, the communication method according to the embodiment of the present application further includes: obtaining a first offset Offset1 and / or a second offset Offset2 before determining the LP-WUS monitoring behavior based on the C-DRX parameters, the Cell DTX parameters, and the LP-WUS monitoring timing; the UE determines the LP-WUS monitoring period based on the first offset Offset1 and / or the second offset Offset2, the first offset Offset1 being used to indicate the offset of the starting point of the monitoring period relative to the starting point of the Cell DTX activation time timer, and the second offset Offset2 being used to indicate the offset of the end time of the monitoring period relative to the starting point of the C-DRX duration timer. In one embodiment, the first offset Offset1 is sent by the base station to the UE, and the second offset Offset2 is sent by the base station to the UE or notified by the UE to the base station. In one embodiment, the value of Offset 1 can be 0.

[0167] In the above embodiment, the second offset Offset2 may be related to the UE capability. Specifically, the UE may report the second offset Offset2 to the base station through UE capability signaling.

[0168] In the above-mentioned embodiment of the present application, the UE receives first information, which includes parameters of Cell DTX and / or parameters of C-DRX, and parameters of LP-WUS; the UE determines the listening timing of LP-WUS based on the parameters of LP-WUS; and the UE determines the listening behavior of LP-WUS based on the parameters of Cell DTX and / or parameters of C-DRX, and the listening timing of LP-WUS, so as to ensure that the understanding of the base station and the UE is consistent, so that normal communication can be achieved between the base station and the UE.

[0169] The communication method provided by the above embodiment of the present application can ensure that the understanding between the base station and the UE is consistent, so that the base station and the UE can communicate normally. However, the above communication method may cause the UE to frequently switch between the MR and LR.

[0170] Specifically, after determining the monitoring behavior of the LP-WUS, the LP-WUS can be activated or deactivated via a timer. That is, the timer can be used to activate or deactivate the LP-WUS. The UE will start the timer based on a conditional trigger. The timer triggering conditions for activating and deactivating the LP-WUS can be the same or different. The present invention does not limit the triggering conditions of the timer.

[0171] In one case, when a condition is met (for example, when the UE receives DCI scheduling data), the UE will start or restart the timer for activating LP-WUS. If there is no data scheduling during the timer running, the UE will continue to run the timer. After the timer times out (that is, the timer expires), the terminal will start monitoring LP-WUS (which can also be understood as the UE returning to LR) and stop monitoring PDCCH (which can also be understood as the UE turning off MR). However, even if there is data to be transmitted during the inactive period of C-DRX and / or the inactive period of Cell DRX, since the base station will not send data scheduling during the inactive period and the UE will not receive DCI, the timer may time out, causing the UE to turn off MR. In this case, if the base station hopes to schedule data to the UE in the next active period of C-DRX and / or active period of Cell DRX, the base station needs to send information again to instruct the UE to return to MR (or instruct the UE to resume monitoring of PDCCH). This will cause the UE to frequently switch between MR and LR, which will cause additional delay in data transmission.

[0172] In another scenario, for a UE at the cell edge, base station coverage may be poor, resulting in the UE not receiving the LP-WUS for an extended period. To ensure system robustness, the UE needs to return to the MR to monitor the PDCCH normally. To this end, a timer for deactivating the LP-WUS is introduced. For example, when a condition is met (e.g., the UE receives the LP-WUS), the timer for deactivating the LP-WUS is started or restarted. In this case, while the timer is running, the UE can also send a feedback message to the base station, confirming that the UE has received the LP-WUS. Thereafter, communication between the base station and the terminal will resume based on the LP-WUS indication information. In one scenario, if the UE does not receive the LP-WUS, the UE will not send a feedback message. Accordingly, the base station, having not received the feedback message, knows that the terminal has not received the LP-WUS and can resend the LP-WUS at the next LP-WUS monitoring opportunity. If the UE does not receive the LP-WUS during the timer, when the timer expires, the UE resumes monitoring the PDCCH (which can also be understood as the UE turning on the MR) and stops monitoring the LP-WUS (which can also be understood as the UE turning off the LR). However, during the inactive period of C-DRX and / or the inactive period of Cell DRX, the base station will not send LP-WUS, and the UE will not receive LP-WUS. The timer may time out, causing the UE to turn off LR (stop monitoring LP-WUS) and turn on MR (resume monitoring of PDCCH), resulting in power consumption waste.

[0173] To this end, an embodiment of the present application further provides a communication method, which includes step S100, step S200 and step S300.

[0174] In step S100, the UE receives first information, which includes Cell DTX parameters and / or C-DRX parameters, and also includes lengths of one or more first timers.

[0175] In one embodiment, the parameters of Cell DTX and C-DRX can be carried by RRC signaling. In one embodiment, the parameters of Cell DTX and C-DRX can be carried by the same RRC signaling or by different RRC signaling. For the signaling of the parameters of Cell DTX and C-DRX, please refer to the above embodiments.

[0176] The length of the first timer may be carried in RRC signaling. The Cell DTX parameter and / or the C-DRX parameter and the length of the first timer may be carried in the same RRC signaling or in different RRC signaling without distinguishing the order.

[0177] The length of the first timer may be carried by a SIB message. In one example, step S100 may include: the UE receiving the length of the first timer carried by the SIB message; and the UE receiving Cell DTX parameters and / or C-DRX parameters carried by RRC signaling.

[0178] The first timer is used to activate or deactivate the LP-WUS.

[0179] The first information also includes the length of one or more first timers. Specific implementation methods include: the first information can configure one or more values ​​for the first timer; or, the first information configures one or more first timers. When multiple first timers are configured, each first timer corresponds to a value, and these values ​​can be different. The embodiments of this application are not limited. The following embodiments all take the former as an example, and the latter is also applicable to the following embodiments and will not be described repeatedly.

[0180] Step S200: When a condition is met, the UE starts or restarts a first timer, which is used to activate or deactivate the LP-WUS. Correspondingly, when a condition is met, the base station may also start or restart the first timer.

[0181] The embodiment of the present application does not limit the conditions for starting or re-starting the first timer. For example, once the UE receives the DCI for scheduling data, the first timer is started or re-started.

[0182] In step S300, the UE determines the behavior or length of the first timer according to the Cell DTX status and / or the C-DRX status, as shown in Figure 17. Correspondingly, the base station may also determine the behavior or length of the first timer.

[0183] The communication method shown in FIG17 can be implemented alone or in combination with the communication method (including step S10, step S20 and step S30) of the above embodiment. The following description will be made by taking the implementation of the communication method shown in FIG17 alone as an example.

[0184] The communication method can be executed by the UE and / or the base station, or can also be executed by a chip in the UE and / or the chip in the base station. The communication method in Figure 17 is executed by the UE in Figure 1 above, and the base station can also execute the corresponding communication method. The communication method provided in the embodiments of the present application can be applicable to the case where the Cell DTX mechanism, the C-DRX mechanism, or the Cell DTX mechanism and the C-DRX mechanism work simultaneously. These three cases will be described separately below.

[0185] The following describes a communication method for activating the timer of the LP-WUS.

[0186] In one embodiment, the communication method includes step S100, step S200 and step S300.

[0187] In step S100, the UE receives first information, where the first information includes Cell DTX parameters and / or C-DRX parameters, and the first information also includes lengths of one or more first timers.

[0188] Step S200: When a condition is met, start running or restart running a first timer, where the first timer is used to activate the LP-WUS.

[0189] Step S300: Determine the behavior or length of the first timer according to the Cell DTX state and / or the C-DRX state.

[0190] Based on this embodiment, by determining the behavior or length of the first timer, it is possible to avoid the UE from frequently switching between the MR and the LR, which would cause additional delay in data transmission.

[0191] 1. Under the Cell DTX mechanism, the first timer is used to activate LP-WUS

[0192] In one embodiment, the communication method includes step S100, step S200 and step S300.

[0193] In step S100 , the UE receives first information, where the first information includes Cell DTX parameters and the length of one or more first timers.

[0194] Step S200: When a condition is met, the UE starts running or restarts a first timer, where the first timer is used to activate the LP-WUS.

[0195] Step S300: According to the Cell DTX status, the UE determines the behavior of the first timer.

[0196] By determining the behavior of the first timer according to the state of Cell DTX (for example, suspending the first timer during the inactive period of Cell DTX), the UE can avoid turning off the MR during the inactive period of Cell DTX, thereby avoiding frequent switching of MR and LR, thereby reducing delay.

[0197] In an exemplary embodiment, step S300 may include: suspending the first timer during the Cell DTX inactive period. In an exemplary embodiment, step S300 may also include: continuing to run the first timer or re-running the first timer during the next Cell DTX active period after suspending the first timer. In this embodiment, in step S100, the first information may include the length of the first timer.

[0198] In an exemplary embodiment, as shown in Figure 18, when the conditions are met, the UE starts running the first timer (as shown in the figure at time t1). During the operation of the first timer, the UE enters the inactive period of Cell DTX (that is, the activation time timer of Cell DTX expires). During the inactive period of Cell DTX, the first timer is suspended until the inactive period of Cell DTX ends (that is, the activation time timer of the next cycle of Cell DTX starts running). The activation time timer of the next cycle of Cell DTX starts running, and the UE continues to run the first timer until the first timer expires (as shown in the figure at time t2). After the first timer expires, the UE monitors LP-WUS, and the UE can also stop monitoring PDCCH. Therefore, through this embodiment, it is avoided that the UE turns off the MR during the inactive period of Cell DTX, so that the UE frequently switches between MR and LR, thereby reducing the delay.

[0199] In another embodiment, the first information includes the lengths of multiple first timers, where the lengths of the first timers include a first value and a second value. The first value and the second value have different values, and depending on different conditions, the UE uses different values ​​as the current length of the first timer. For example, when Cell DTX is enabled, the first value is used as the length of the first timer, and when Cell DTX is disabled, the second value is used as the length of the first timer. The first value is greater than the second value. The first value and the second value can be in units of seconds, milliseconds, frames, subframes, or time slots, etc., but the embodiments of the present application are not limited thereto.

[0200] In an exemplary embodiment, the length of the first timer used when Cell DTX is enabled is extended compared to the length of the first timer used when Cell DTX is disabled. For example, when Cell DTX is enabled, the first value is used as the length of the first timer, and when Cell DTX is disabled, the extended first value is used as the length of the first timer, that is, the length of the first timer is the sum of the first value and an increase.

[0201] Through this embodiment, under the Cell DTX mechanism, a longer first timer is used to avoid the UE turning off the MR during the inactive period of Cell DTX, thereby reducing frequent switching between the MR and the LR.

[0202] It should be noted that there may be a time interval between the time position when the first timer expires and the time position when the UE starts monitoring the LP-WUS, and the present invention is not limited to this.

[0203] 2. Under the C-DRX mechanism, the first timer is used to activate LP-WUS

[0204] In one embodiment, the communication method includes step S100, step S200 and step S300.

[0205] Step S100: The UE receives first information, where the first information includes C-DRX parameters and the length of one or more first timers.

[0206] Step S200: When a condition is met, the UE starts running or restarts a first timer, where the first timer is used to activate the LP-WUS.

[0207] Step S300: The UE determines the behavior of the first timer according to the C-DRX state.

[0208] By determining the behavior of the first timer according to the state of C-DRX (for example, suspending the first timer during the inactive period of C-DRX), it is possible to avoid the UE turning off the MR during the inactive period of C-DRX, thereby avoiding frequent switching between the MR and LR, thereby reducing latency.

[0209] In an exemplary embodiment, step S300 may include: suspending the first timer during a C-DRX inactive period. In an exemplary embodiment, step S300 may also include: continuing to run the first timer or re-running the first timer during the next C-DRX active period after suspending the first timer. In this embodiment, in step S100, the first information may include a length of the first timer.

[0210] In an exemplary embodiment, when a condition is met, the UE starts running a first timer. During the operation of the first timer, the UE enters a C-DRX inactive period (i.e., the C-DRX duration timer, the C-DRX inactive timer, the C-DRX downlink retransmission timer, and the C-DRX uplink retransmission timer all expire) or at least one of the C-DRX duration timer, the C-DRX inactive timer, the C-DRX downlink retransmission timer, or the C-DRX uplink retransmission timer expires. During the C-DRX inactive period, the first timer is suspended until the C-DRX inactive period ends (e.g., the duration timer of the next C-DRX cycle starts running). Alternatively, when at least one of the C-DRX duration timer, the C-DRX inactive timer, the C-DRX downlink retransmission timer, or the C-DRX uplink retransmission timer expires, the first timer is suspended until the C-DRX inactive period ends (e.g., the duration timer of the next C-DRX cycle starts running). When the duration timer of the next C-DRX cycle starts running, the UE continues to run the first timer until the first timer expires. After the first timer expires, the UE monitors the LP-WUS and may also stop monitoring the PDCCH. This embodiment prevents the UE from turning off the MR during the C-DRX inactive period, thereby preventing the UE from frequently switching between the MR and LR, thereby reducing latency.

[0211] In another embodiment, the first information includes the lengths of multiple first timers, where the lengths of the first timers include a first value and a second value. The first value and the second value have different values. Depending on different conditions, the UE uses different values ​​as the current length of the first timer. For example, when C-DRX is activated, the first value is used as the length of the first timer, and when C-DRX is deactivated, the second value is used as the length of the first timer. The first value is greater than the second value. The first value and the second value can be in units of seconds, milliseconds, frames, subframes, or time slots, etc., but the embodiments of the present application are not limited thereto.

[0212] In an exemplary embodiment, the length of the first timer used when C-DRX is activated is extended compared to the length of the first timer used when C-DRX is deactivated. For example, when C-DRX is enabled, the first value is used as the length of the first timer, and when C-DRX is disabled, the extended first value is used as the length of the first timer, that is, the length of the first timer is the sum of the first value and an increase.

[0213] Through this embodiment, under the C-DRX mechanism, a longer first timer is used to avoid the UE turning off the MR during the C-DRX inactive period, thereby reducing frequent switching between the MR and the LR.

[0214] It should be noted that there may be a time interval between the time position when the first timer expires and the time position when the UE starts monitoring the LP-WUS, and the present invention is not limited to this.

[0215] 3. Under the Cell DTX mechanism and C-DRX mechanism, the first timer is used to activate LP-WUS

[0216] In one embodiment, the communication method includes step S100, step S200 and step S300.

[0217] In step S100, the UE receives first information, where the first information includes parameters of Cell DTX and C-DRX, and also includes lengths of one or more first timers.

[0218] Step S200: When a condition is met, the UE starts running or restarts a first timer, where the first timer is used to activate the LP-WUS.

[0219] Step S300: The UE determines the behavior of the first timer according to the C-DRX status and the Cell DTX status.

[0220] Based on this embodiment, frequent switching between MR and LR is avoided, thereby reducing delay.

[0221] In an exemplary embodiment, when C-DRX and Cell DTX are operating simultaneously, step S300 may include: suspending the first timer during a C-DRX inactive period or a Cell DTX inactive period. In an exemplary embodiment, step S300 may include: after suspending the first timer, continuing to run the first timer or re-running the first timer during a Cell DTX active period and a C-DRX active period. In this embodiment, in step S100, the first information may include a length of the first timer.

[0222] In an exemplary embodiment, when a condition is met, the UE starts running a first timer. During the operation of the first timer, the UE enters the inactive period of Cell DTX (i.e., the activation time timer of Cell DTX expires) or the inactive period of C-DRX (i.e., the duration timer of C-DRX, the inactive timer of C-DRX, the downlink retransmission timer of C-DRX, and the uplink retransmission timer of C-DRX all expire) or at least one of the duration timer of C-DRX, the inactive timer of C-DRX, the downlink retransmission timer of C-DRX, or the uplink retransmission timer of C-DRX expires. During the inactive period of Cell DTX or the inactive period of C-DRX, the first timer is suspended until the inactive period of Cell DTX or the inactive period of C-DRX ends (for example, the activation time timer of the next cycle of Cell DTX starts running or the duration timer of the next cycle of C-DRX starts running). Alternatively, at least one of the activation time timer of Cell DTX, the duration timer of C-DRX, the inactivation timer of C-DRX, the downlink retransmission timer of C-DRX, or the uplink retransmission timer of C-DRX expires, and the first timer is suspended until the inactivation period of Cell DTX or the inactivation period of C-DRX ends. When the activation time timer of the next cycle of Cell DTX starts running or the duration timer of the next cycle of C-DRX starts running, the UE continues to run the first timer until the first timer expires. After the first timer expires, the UE monitors LP-WUS, and the UE may also stop monitoring PDCCH. Through this embodiment, it is avoided that the UE turns off the MR during the inactivation period of Cell DTX, so that the UE frequently switches between MR and LR, thereby reducing the delay.

[0223] In another exemplary embodiment, the first information includes the lengths of multiple first timers, where the lengths of the first timers include a first value and a second value. The first value and the second value have different values, and the UE uses different values ​​as the current length of the first timer according to different conditions. For example, when Cell DTX is enabled or C-DRX is enabled, the first value is used as the length of the first timer; when Cell DTX is disabled or C-DRX is disabled, the second value is used as the length of the first timer. The first value is greater than the second value. The first value and the second value can be in units of seconds, milliseconds, frames, subframes, or time slots, etc., but the embodiments of the present application are not limited thereto.

[0224] In an exemplary embodiment, compared to the length of the first timer used when Cell DTX is disabled or C-DRX is enabled, the length of the first timer used when Cell DTX is disabled or C-DRX is enabled is extended. For example, when Cell DTX is enabled or C-DRX is enabled, a first value is used as the length of the first timer, and when Cell DTX is disabled or C-DRX is disabled, the length of the first timer used is extended, that is, the length of the first timer is the sum of the first value and an increase.

[0225] Through this embodiment, when C-DRX and Cell DTX work simultaneously, a longer first timer is used to avoid the UE turning off the MR during the C-DRX inactive period, thereby reducing frequent switching between the MR and LR.

[0226] The following describes a communication method for deactivating the timer of the LP-WUS.

[0227] In one embodiment, the communication method includes step S100, step S200 and step S300.

[0228] In step S100, the UE receives first information, where the first information includes Cell DTX parameters and / or C-DRX parameters, and the first information also includes lengths of one or more first timers.

[0229] Step S200: When a condition is met, start running or restart running a first timer, where the first timer is used to deactivate the LP-WUS.

[0230] Step S300: Determine the behavior or length of the first timer according to the Cell DTX state and / or the C-DRX state.

[0231] The method for determining the behavior or length of the first timer in this embodiment is the same as the method for determining the behavior or length of the first timer in the above embodiment (regarding the communication method for activating the timer for the LP-WUS), and will not be repeated here. The communication method of this embodiment differs from the above embodiment in that after the first timer expires, the UE monitors the PDCCH and can also stop monitoring the LP-WUS.

[0232] Through this embodiment, the power consumption waste caused by the UE turning off the LR and turning on the MR due to the expiration of the first timer can be avoided.

[0233] In the connected state, LP-WUS is at least used to instruct the UE to monitor the PDCCH. In addition, LP-WUS can also be used to carry other functions, such as parameter adjustment of Cell DTX, activation / deactivation of Cell DTX, parameter adjustment of C-DRX, activation / deactivation of semi-persistently scheduled PDSCH, activation / deactivation of semi-persistently scheduled PUSCH, switching of search space set groups, etc. In order to support more functions, LP-WUS requires more bits. Since the base station can also be configured by the UE with multiple semi-persistently scheduled PDSCH resources and / or multiple semi-persistently scheduled PUSCHs, if LP-WUS can indicate activation / deactivation of semi-persistently scheduled PDSCH, or activation / deactivation of semi-persistently scheduled PUSCH, LP-WUS requires more bits. However, considering the detection performance of LP-WUS, the code rate of LP-WUS is usually low and the number of bits that can be carried is limited.

[0234] To this end, the present application also provides a communication method, which includes steps S1000 and S2000.

[0235] In step S1000, a UE receives first information, where the first information includes parameters of a low power wake-up signal (LP-WUS), where the parameters of the LP-WUS include a time domain position and / or a frequency domain position of the LP-WUS.

[0236] Correspondingly, the base station may also send the first information.

[0237] In step S2000, the UE receives the LP-WUS according to the parameters of the LP-WUS. The LP-WUS carries different functions using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), and code division multiplexing (CDM). The communication method can be performed by a UE (such as the UE in Figure 1) and a base station (such as the base station in Figure 1), or by a chip in the UE and a chip in the base station.

[0238] Accordingly, the base station may send the LP-WUS according to the parameters of the LP-WUS.

[0239] In an embodiment of the present application, the UE receives the LP-WUS according to the parameters of the LP-WUS (for example, the time domain position and / or frequency domain position of the LP-WUS), and the LP-WUS carries different functions through one or more of TDM, FDM, and CDM, so that the LP-WUS with a limited number of bits can carry more functions.

[0240] In one embodiment, the step of receiving the LP-WUS includes: distinguishing the functions carried by the LP-WUS based on the different time domain positions of the LP-WUS listening opportunities, that is, the LP-WUS carries different functions via TDM. For example, the UE monitors the LP-WUS at the LP-WUS listening opportunity at time T-1, and the LP-WUS received at time T-1 is used to carry a first function (e.g., instructing to monitor the PDCCH). The UE monitors the LP-WUS at the LP-WUS listening opportunity at time T-2, and the LP-WUS received at time T-2 is used to carry a second function (e.g., instructing to activate or deactivate a semi-persistently scheduled PDSCH), as shown in Figure 20. In an exemplary embodiment, in step S1000, the listening opportunities of the LP-WUS for different functions can be configured. For example, different periods can be configured for the LP-WUS, with the LP-WUS of the first period being used to carry the first function and the LP-WUS of the second period being used to carry the second function. The embodiments of the present application are not limited thereto. The periods of the LP-WUS carrying different functions can be three or more. In an exemplary embodiment, the UE can determine the function of the LP-WUS based on different listening opportunities.

[0241] In one embodiment, the step of receiving the LP-WUS includes distinguishing the functions carried by the LP-WUS based on the frequency domain location of the LP-WUS monitoring opportunity, that is, the LP-WUS carries different functions via FDM. For example, the base station configures multiple frequency locations for the LP-WUS, and the UE also monitors the LP-WUS at these multiple frequency domain locations (e.g., monitoring a first LP-WUS, a second LP-WUS, and a third LP-WUS for different functions), as shown in FIG21. In an exemplary embodiment, the base station can be configured to monitor the LP-WUS at different times and in different frequency domains to facilitate the UE to implement the above method.

[0242] In one embodiment, the step of receiving the LP-WUS includes: distinguishing the functions carried by the LP-WUS according to the sequence of the LP-WUS, that is, the LP-WUS carries different functions by means of CDM. In an exemplary embodiment, if the LP-WUS is monitored as sequence 1, it indicates that it is used to carry the first function (for example, indicating monitoring PDCCH), and if the LP-WUS is monitored as sequence 2, it indicates that it is used to carry the second function (for example, indicating activation or deactivation of PDSCH for semi-persistent scheduling), as shown in Figure 22. The embodiments of the present application are not limited to this. The sequences of the LP-WUS carrying different functions monitored can be three or more.

[0243] In one embodiment, the terminal may also use two or three of the TDM, FDM, and CDM methods to distinguish different functions of the LP-WUS.
