Description

[0001] This application is a divisional application of the invention patent application with the application date of August 7, 2020, application number 202080102967.4, and name “Wireless Communication Method and Device”. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and more specifically, to wireless communication methods and devices. Background Art

[0003] Device-to-device communication is a sidelink (SL) transmission technology based on device-to-device (D2D). It differs from the way communication data is received or sent by base stations in traditional cellular systems. D2D can include scenarios such as proximity-based services (ProSe), vehicle-to-everything (V2X), and wearable devices (FeD2D). For example, V2X communication is also called vehicle-to-vehicle communication. V2X communication uses direct terminal-to-terminal communication, so it has higher spectrum efficiency and lower transmission latency.

[0004] However, for D2D communication, a discontinuous reception (DRX) mechanism is not considered, which is equivalent to the terminal device being in a continuous reception state, resulting in excessive power consumption of the terminal device. Summary of the Invention

[0017] In a ninth aspect, a terminal device is provided, comprising a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and execute the computer program stored in the memory to execute the method of the third aspect or its respective implementations.

[0018] In a tenth aspect, a chip is provided for implementing the method of any one of the first to third aspects or their respective implementations. Specifically, the chip includes a processor for loading and executing a computer program from a memory, causing a device equipped with the chip to perform the method of any one of the first to third aspects or their respective implementations.

This is particularly true for special types of messages, such as messages that need to be sent before establishing a connection between terminals. This not only ensures normal data transmission but also reduces power consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0029] Figure 1 or Figure 2 The system framework of vehicle terminal to vehicle terminal is shown.

[0030] like Figure 1 As shown, the transmission resources of terminal device 121 and terminal device 122 are allocated by network device 110, and terminal device 121 and terminal device 122 send data on the side link according to the resources allocated by network device 110; network device 110 can allocate resources for single transmission to terminal device 121 and terminal device 122, and can also allocate resources for semi-static transmission to terminal device 121 and terminal device 122.

[0031] like Figure 2 As shown, the vehicle-mounted terminal 131 and the vehicle-mounted terminal 132 can select a resource in the resource pool to transmit data.

[0032] It should be understood that the terminal device involved in the embodiments of the present application can be any device or apparatus configured with a physical layer and a media access control layer, and the terminal device can also be referred to as an access terminal. For example, user equipment (UE), subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other linear processing device connected to a wireless modem, an in-vehicle device, a wearable device, and the like.

[0033] It should be noted that the embodiments of the present application are applicable to any terminal-to-terminal communication framework, such as vehicle-to-vehicle (V2V), vehicle-to-everything (V2X), and device-to-device (D2D).

[0034] Taking the D2D as an example, the D2D may include scenarios such as Proximity Based Service (ProSe), Vehicle to Everything (V2X), and Wearable Devices (FeD2D). The main services facing the ProSe scenario may include public safety services. The V2X scenario may be a vehicle-to-vehicle communication scenario, and its main services may include relatively high-speed vehicle-to-vehicle and vehicle-to-person communication services. The FeD2D scenario may be a scenario in which a wearable device accesses the network through a mobile phone, and its main services may include services in low-speed and low-power access scenarios.

[0035] In the embodiments provided in the present application, the terminal device involved above may receive or send data based on discontinuous reception (DRX), or may be in a state of continuously receiving data.

[0036] For example, in ProSe scenarios, DRX configurations can be pre-configured or configured by network devices. Based on the timing reference signals transmitted by network devices or terminal devices, communicating terminal devices can only transmit and receive data if they have the same DRX configuration, i.e., the same pre-configured or network-configured DRX configuration, and the terminal devices have the same understanding of the DRX configuration.

[0037] For example, in the V2X scenario, since automotive terminals have a fixed power input, DRX configuration can be ignored for data transmission after the connection is established, that is, it is assumed that the automotive terminal is always in a continuous receiving state; although handheld terminals do not have a fixed power supply, since DRX and the low latency requirements of the Internet of Vehicles are inconsistent, DRX configuration can also be ignored for data transmission after the connection is established.

[0038] For example, in the FeD2D scenario, for the DRX mode used when communicating between a wearable device and a mobile phone, the network device configures the DRX configuration for the remote terminal through the relay terminal. After receiving the DRX configuration configured by the network device, the remote terminal communicates with the relay terminal using the DRX configuration.

[0039] Figure 3 FIG2 shows a schematic flow chart of a wireless communication method 300 according to an embodiment of the present application, which may be executed by a terminal device. Figure 1 The terminal device shown or Figure 2 The vehicle terminal shown.

[0040] like Figure 3 As shown, the method 300 may include:

[0041] S310: Receive the first message based on a first discontinuous reception (DRX) configuration corresponding to the first message.

[0042] By configuring the DRX configuration corresponding to the first message and receiving the first message, DRX and D2D communication can be combined, thereby reducing power consumption. This is particularly true for special types of messages, such as those required to be sent before establishing a connection between terminals. This not only ensures normal data transmission but also reduces power consumption.

[0043] For example, a message to be sent before connection establishment may be received based on DRX. In addition, a message to be sent after connection establishment may be received based on a DRX configuration configured by a network device or a DRX configuration configured by a network device via a relay terminal.

[0044] In other words, the first message may be a message that needs to be received before a connection is established between terminal devices.

[0045] In some embodiments of the present application, the first message includes at least one of the following messages: a system message, a paging message, and a device discovery message.

[0046] For example, the terminal device may receive the system message based on the DRX configuration corresponding to the system message.

[0047] In some embodiments of the present application, the first DRX configuration is a dedicated configuration for the first message. In other words, the first DRX configuration is only used to receive the first message.

[0048] In some embodiments of the present application, the first message corresponds to a first identifier, and the first identifier corresponds to the first DRX configuration.

[0049] In other words, the first message needs to correspond to the first DRX configuration through the first identifier.

[0050] In some embodiments of the present application, the first identifier includes at least one of the following: a terminal identifier, a terminal group identifier, a message type identifier, a transmission identifier, and an application identifier.

[0051] Taking the first identifier as a terminal identifier as an example, the terminal device may determine the message corresponding to the terminal identifier as the first message, and determine the DRX configuration corresponding to the terminal identifier as the first DRX configuration, and then, the terminal device may receive the first message based on the first DRX configuration.

[0052] In some embodiments of the present application, the first identifier is a layer 2 address.

[0053] For example, the layer 2 address may be a Media Access Control (MAC) address of the terminal device.

[0054] In some embodiments of the present application, the method 300 may include:

[0055] Based on at least one synchronization source, determine a time resource corresponding to the first DRX configuration.

[0056] In some embodiments of the present application, the at least one synchronization source includes a synchronization source of a terminal device.

[0057] For example, the at least one synchronization source may include a global positioning system (GPS), access network equipment, and terminal equipment.

[0058] In some embodiments of the present application, the at least one synchronization source includes a synchronization source corresponding to at least one receivable synchronization signal.

[0059] In some embodiments of the present application, the method 300 may include:

[0060] Indication information is received, where the indication information is used to indicate that data to be transmitted does not include the first message or includes the first message.

[0061] For example, based on the received indication information, the terminal device can determine whether there is a physical sidelink control channel (PSCCH) and / or physical sidelink shared channel (PSSCH) related to the first message during the activation period corresponding to the DRX configuration.

[0062] In some embodiments of the present application, the method 300 may include:

[0063] If the indication information indicates that the data to be transmitted includes the first message, the first message is received.

[0064] Of course, if the indication information indicates that the data to be transmitted does not include the first message, the first message is not received.

[0065] The indication information can prevent the terminal device from receiving useless messages, and accordingly, the power consumption of the terminal device can be further reduced.

[0066] In some embodiments of the present application, the indication information is carried in at least one field in the sidelink control information (SCI), and / or the indication information indicates through the format of the SCI that the data to be transmitted does not include the first message or includes the first message.

[0067] In some embodiments of the present application, the indication information is carried in at least one field in the MAC message header, and / or the indication information indicates through the format of the MAC message header whether the data to be transmitted does not include the first message or includes the first message.

[0068] For example, the indication information may be carried in at least one field in a header of a MAC protocol data unit (PDU). For another example, the indication information may be carried in at least one field in a header of a MAC sub-PDU. In other words, the indication information may be carried in at least one field in a main header of a MAC PDU, or in at least one field in a sub-header of a MAC PDU.

[0069] For another example, the indication information indicates that the data to be transmitted does not include the first message through the first format of the SCI, and the indication information indicates that the data to be transmitted includes the first message through the second format of the SCI, and the first format is different from the second format.

[0070] In some embodiments of the present application, the method 300 may be applied to device-to-device D2D communication.

[0071] For example, the method 300 may be applied to scenarios such as ProSe, V2X, and FeD2D.
