However, the following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following descriptions, although these technologies can also be applied to applications other than NR system applications, such as the 6th generation (6 th Generation, 6G) communication system.

[0042] Figure 1A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a terminal 11 and a network side device 12. Among them, the terminal 11 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal side devices, and the wearable device includes: a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0043] The following first introduces the communication terms related to this application.

[0044] 1. Sidelink Introduction

[0045] The Long Term Evolution (LTE) system has supported sidelinks since its 12th release, which are used for direct data transmission between user equipment (UE) without going through network-side devices.

[0046] LTE sidelink is designed for specific public safety matters (such as emergency communications in disaster sites such as fires or earthquakes), or vehicle to everything (V2X) communications. Vehicle to everything communications include various services, such as basic safety communications, advanced (autonomous) driving, platooning, sensor expansion, etc. Since LTE sidelink only supports broadcast communications, it is mainly used for basic safety communications. Other advanced V2X services with strict quality of service (QoS) requirements in terms of latency, reliability, etc. will be supported by the New Radio (NR) sidelink.

[0047] The 5G NR system can be used in the operating frequency band above 6GHz which is not supported by LTE, and supports a larger operating bandwidth. However, the current version of the NR system only supports the interface between the base station and the terminal, and does not yet support the Sidelink interface for direct communication between terminals. The Sidelink link interface can also be called the PC5 interface.

[0048] 2. Sidelink transmission form

[0049] The current sidelink transmission is mainly divided into broadcast, groupcast, and unicast transmission forms. Unicast, as the name implies, is one-to-one transmission. Multicast is one-to-many transmission. Broadcast is also one-to-many transmission, but broadcast does not have the concept of UE belonging to the same group.

[0050] Currently, Sidelink unicast and multicast communications support the physical layer Hybrid Automatic Repeat reQuest (HARQ) feedback mechanism.

[0051] 3. Resource allocation mode 1 and mode 2

[0052] The resource allocation modes of Sidelink UE are divided into two categories:

[0053] 1) Base station scheduling mode (Mode 1): The base station controls and allocates resources to each UE.

[0054] 2) UE autonomous mode (Mode 2): Each UE independently selects resources.

[0055] 4. SL protocol stack

[0056] Traditional SL (sidelink) interface, such as Figure 2As shown in FIG, the User Plane (UP) protocol stack between two UEs includes from bottom to top: physical layer (PHY), media access control (MAC), radio link control (RLC), packet data convergence protocol (PDCP), and service data adaptation protocol (SDAP). Figure 3 As shown, the control plane (CP) protocol stack includes from bottom layer to high layer: PHY, MAC, RLC, PDCP, and radio resource control (RRC) (PC5-S).

[0057] Currently, SL does not support interoperability with WLAN, so there is no relevant protocol stack or / and interface between WLAN and SL nodes.

[0058] In the following, in conjunction with the accompanying drawings, the SL and WLAN interoperability method, apparatus and communication equipment provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.
