[0029] The technical solution in this application will be described below with reference to the accompanying drawings.

[0030] FIG1 illustrates a wireless communication system 100 used in an embodiment of the present application. The wireless communication system 100 may include a network device 110 and a user equipment (UE) 120. The network device 110 may communicate with the UE 120. The network device 110 may provide communication coverage for a specific geographic area and may communicate with the UE 120 within the coverage area. The UE 120 may access a network (e.g., a wireless network) through the network device 110.

[0031] Figure 1 exemplarily shows a network device and two UEs. Optionally, the wireless communication system 100 may include multiple network devices, and each network device may include a different number of terminal devices within its coverage area, which is not limited in this embodiment of the present application. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in this embodiment of the present application.

[0032] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: fifth generation (5G) system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

[0033] The UE in the embodiments of the present application may also be referred to as a terminal device, an access terminal, a user unit, a user station, a mobile station, a mobile station (MS), a mobile terminal (MT), a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. The UE in the embodiments of the present application may refer to a device that provides voice and / or data connectivity to a user and can be used to connect people, objects, and machines, such as a handheld device or an in-vehicle device with wireless connection capabilities. The UE in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. Optionally, the UE can be used to act as a base station. For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in V2X or D2D, etc. For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through a base station.

[0034] The network device in the embodiments of the present application may be a device for communicating with a UE, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a UE to a wireless network. A base station may broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station may be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof.

[0035] In some embodiments, the network device can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile network device, and one or more cells can move according to the location of the mobile network device. In other examples, the helicopter or drone can be configured to act as a device for communicating with another network device. In some embodiments, the network device can refer to a CU or a DU, or the network device can include a CU and a DU, or the network device can also include an AAU.

[0036] It should be understood that network devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water; and can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the network devices and the scenarios in which they are used.

[0037] It should also be understood that all or part of the functions of the network device and UE in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0038] In some communication systems, idle or inactive devices can periodically wake up to receive paging messages from the network. This is known as discontinuous reception (DRX). Each wake-up period is called a DRX cycle. A DRX cycle can contain several paging frames (PFs), and a PF corresponds to several paging occasions (POs). A device can receive paging messages only on a specific PO.

[0039] During the non-access stratum (NAS) registration process, the Access and Mobility Management Function (AMF) can negotiate a UE-specific DRX cycle. This negotiation is transparent to the base station, so the base station may not be aware of the DRX cycle the UE is using. However, the AMF can also provide information about the UE-specific DRX cycle to the base station using the "Core Network Assistance Information" parameter structure. This parameter structure can be included in the application layer signaling protocol (NG application protocol, NGAP), such as the Initial Context Setup Request message, the UE Context Modification Request message, the Handover Request message, or the Path Switch Request Confirmation message.

[0040] The DRX cycle is defined as the default paging cycle (e.g., default DRX cycle) broadcast in system information block 1 (SIB1), unless a UE-specific value (e.g., UE-specific DRX cycle) has been configured. If a UE-specific DRX cycle is configured, the DRX cycle is the minimum of the default paging cycle and the UE-specific DRX cycle.

[0041] Version 18 (R18) of the communication protocol introduces the low-power, high-accuracy positioning (LPHAP) feature, designed to improve the user experience for terminal services such as those used in factories where workpieces require long standby times, one of which is positioning. One topic discussed during the standards meeting was extending the existing DRX cycle, increasing the maximum cycle from 10.24 seconds to, for example, 20.48 seconds. This would further reduce power consumption in terminal devices at the expense of increased data transmission latency.

[0042] However, if the default DRX cycle broadcast in SIB1 is simply extended to a value greater than 10.24s, then those terminal devices that do not require energy saving will also need to apply this DRX cycle, which will seriously affect the data transmission delay of these terminal devices that do not require energy saving.

[0043] In order to solve one or more of the above-mentioned technical problems, the present application proposes a communication method and a communication device, which can extend the DRX cycle of energy-saving terminal equipment (i.e., terminal equipment with energy-saving requirements) without affecting the data transmission delay of existing non-energy-saving terminal equipment (i.e., terminal equipment without energy-saving requirements), thereby reducing the power consumption overhead of the energy-saving terminal equipment.

[0044] The embodiments of the present application are described in detail below with reference to FIG. 2 to FIG. 4 .

[0045] FIG2 is a schematic flow chart of a communication method according to an embodiment of the present application. The method 200 shown in FIG2 may include steps S210 and S220, which are as follows:

[0046] S210: The network device sends first information to the terminal device.

[0047] The first information may be used to indicate a first DRX cycle corresponding to the energy-saving function. For example, the first information may include two fields, one field may indicate the energy-saving function or the non-energy-saving function, and the other field may indicate the value of the DRX cycle. Alternatively, the two fields may correspond to the energy-saving function and the non-energy-saving function, respectively, that is, one field is used to indicate the DRX cycle corresponding to the energy-saving function, and the other field is used to indicate the DRX cycle corresponding to the non-energy-saving function. Of course, these embodiments are merely examples and not limitations, and the manner of indicating the first information in the embodiments of the present application is not limited.

[0048] Optionally, the energy-saving function may include an LPHAP positioning function, or may include other functions corresponding to energy-saving requirements.

[0049] Optionally, the first DRX cycle may be a user equipment UE-specific DRX cycle corresponding to an energy saving function, for example, an LPHAP UE-specific DRX cycle corresponding to an LPHAP positioning function.

[0050] Alternatively, the first DRX cycle may also be a default DRX cycle corresponding to the energy saving function, for example, an LPHAP default DRX cycle corresponding to the LPHAP positioning function.

[0051] Optionally, in S210, the network device may send the first information to the terminal device via radio resource control (RRC) signaling or non-access stratum (NAS) signaling.

[0052] Optionally, in S210, the network device may also send the first information to the terminal device via a broadcast message (such as SIB1).

[0053] Optionally, the network device may be an access network device, such as RAN or next generation radio access network (NG-RAN), or a core network element, such as AMF or session management function (SMF).

[0054] Optionally, when the network device is a core network element, the network device may send the first information through the access network device. In this case, the access network device may only transparently transmit the first information without performing any processing on the first information.

[0055] Optionally, the terminal device may be an energy-saving terminal device, or a non-energy-saving terminal device.

[0056] The terminal device may be pre-configured with an energy-saving function, that is, the terminal device may be pre-configured as an energy-saving terminal device.

[0057] Alternatively, the terminal device may also be configured with an energy-saving function by the network device. For example, the network device may send a second message to the terminal device, and the second message may be used to configure the energy-saving function for the terminal device or instruct the terminal device to configure (or apply) the energy-saving function. Furthermore, the terminal device may configure the energy-saving function based on the second message.

[0058] Optionally, the second information and the first information may be sent simultaneously, for example, the second information and the first information may be carried in the same message, or the second information and the first information may be the same information.

[0059] Optionally, the second information and the first information may not be sent at the same time.

[0060] Optionally, the terminal device may be in an idle state or an inactive state.

[0061] S220, the terminal device determines the target DRX cycle of the terminal device based on the first information.

[0062] Optionally, the target DRX cycle may refer to the DRX cycle actually applied by the terminal device.

[0063] In some embodiments, the terminal device may determine the target DRX cycle based on the first DRX cycle and the second DRX cycle. Optionally, the first DRX cycle may be a UE-specific DRX cycle corresponding to the energy saving function, and the second DRX cycle may be a default DRX cycle.

[0064] Optionally, the terminal device may determine the maximum value of the first DRX cycle and the second DRX cycle as the target DRX cycle. For example, the target DRX cycle = MAX (LPHAP UE specific DRX cycle, default DRX cycle). In some embodiments, the terminal device may also directly determine the first DRX cycle as the target DRX cycle without comparing it with the second DRX cycle. In this case, the terminal device may be an energy-saving terminal device.

[0065] Optionally, the terminal device may also determine the minimum value of the first DRX cycle and the second DRX cycle as the target DRX cycle. For example, target DRX cycle = MIN (LPHAP UE specific DRX cycle, default DRX cycle). In this case, the terminal device may be a non-energy-saving terminal device.

[0066] In some embodiments, the terminal device may determine a target DRX cycle based on the first DRX cycle and the third DRX cycle. Optionally, the first DRX cycle may be a default DRX cycle corresponding to the energy-saving function, and the third DRX cycle may be a UE-specific DRX cycle of the terminal device. Optionally, the third DRX cycle may be a UE-specific DRX cycle (other than the UE-specific DRX cycle corresponding to the energy-saving function) in the prior art.

[0067] Optionally, the terminal device may determine the minimum value between the first DRX cycle and the third DRX cycle as the target DRX cycle. For example, the target DRX cycle = min (LPHAP default DRX cycle, UE specific DRX cycle). In some embodiments, the terminal device may also directly determine the first DRX cycle as the target DRX cycle without comparing it with the third DRX cycle. In this case, the terminal device may be an energy-saving terminal device.

[0068] Optionally, the terminal device may also determine the target DRX cycle based on the first DRX cycle and the third DRX cycle, or determine the target DRX cycle based on the second DRX cycle and the third DRX cycle based on the second DRX cycle. Optionally, the second information may be used to configure an energy-saving function for the terminal device or instruct the terminal device to configure (or apply) the energy-saving function, and the second DRX cycle may be a default DRX cycle.

[0069] For example, if the second information can instruct the terminal device to apply the energy-saving function, the terminal device can determine the target DRX cycle based on the first DRX cycle and the third DRX cycle according to the second information, that is, at this time the terminal device is an energy-saving terminal device, and the target DRX cycle = min (LPHAP default DRX cycle, UE specific DRX cycle); otherwise, the terminal device can determine the target DRX cycle based on the second DRX cycle and the third DRX cycle, that is, at this time the terminal device is a non-energy-saving terminal device, and the target DRX cycle = min (default DRX cycle, UE specific DRX cycle).

[0070] In an embodiment of the present application, the first information is used to indicate the first DRX cycle corresponding to the energy-saving function. The terminal device determines the target DRX cycle of the terminal device based on the first information. The DRX cycle of the energy-saving terminal device can be increased without affecting the transmission delay of the non-energy-saving terminal device, thereby helping to reduce the power consumption overhead of the energy-saving terminal device.

[0073] S310: The network device sends a UE-specific DRX cycle corresponding to the LPHAP function to the UE.

[0074] The network device may be a base station (gNB) or a core network element. As shown in Figure 3, if the network device is a base station, then in S310a, the base station may directly send the UE-specific DRX cycle corresponding to the LPHAP function to the UE; if the network device is a core network element, then in S310b, the base station may send the UE-specific DRX cycle corresponding to the LPHAP function to the UE via the base station.

[0075] Optionally, the UE-specific DRX cycle corresponding to the LPHAP function may be longer than 10.24 seconds (s).

[0076] Optionally, the UE may be configured by the core network to apply LPHAP-related functions. For example, in S310 , the network device may simultaneously configure LPHAP-related functions for the UE; or the UE itself may be pre-configured to apply LPHAP-related functions.

[0077] S320: The UE applies the formula MAX(LPHAP UE specific DRX cycle, default DRX cycle) to determine the target DRX cycle.

[0078] Optionally, the target DRX cycle may refer to the DRX cycle actually applied by the terminal device.

[0079] Optionally, if the UE is a terminal device without energy-saving function, the target DRX cycle can be determined using the method in the prior art, for example, the default DRX cycle can be used as the target DRX cycle.

[0080] FIG4 is a schematic flow chart of a communication method according to an embodiment of the present application. The method 400 shown in FIG4 may include steps S410 and S420, which are as follows:

[0081] S410 , the network device sends a UE-specific DRX cycle corresponding to the LPHAP function to the UE.

[0082] The network device may be a base station (gNB) or a core network element. As shown in FIG4 , if the network device is a base station, then in S410a, the base station may directly send the UE-specific DRX cycle corresponding to the LPHAP function to the UE; if the network device is a core network element, then in S410b, the base station may send the UE-specific DRX cycle corresponding to the LPHAP function to the UE via the base station.

[0083] Optionally, the UE-specific DRX cycle corresponding to the LPHAP function may be longer than 10.24 seconds (s).

[0084] Optionally, the UE may be configured by the core network to apply LPHAP-related functions. For example, in S410 , the network device may simultaneously configure LPHAP-related functions for the UE; or the UE itself may be pre-configured to apply LPHAP-related functions.

[0085] S420: The UE applies the formula min(LPHAP default DRX cycle, UE specific DRX cycle) to determine the target DRX cycle.

[0086] Optionally, the target DRX cycle may refer to the DRX cycle actually applied by the terminal device.

[0087] Optionally, before S420, the UE may also determine whether to apply the default DRX cycle or the LPHAP default DRX cycle to determine the target DRX cycle according to its own situation.

[0088] Optionally, the UE may determine the target DRX cycle according to the default DRX cycle or the LPHAP default DRX cycle based on whether the UE is an energy-saving terminal device.

[0089] For example, if the UE is an energy-saving terminal device, S420 can be executed, that is, the UE can determine the target DRX cycle = min (LPHAP default DRX cycle, UE specific DRX cycle); if the UE is a non-energy-saving terminal device, the UE can determine the target DRX cycle = min (default DRX cycle, UE specific DRX cycle).
