Description

[0001] This invention application is a divisional application of the invention application with application date of August 6, 2018, application number 201810887039.8, and invention name “Multi-mode communication method, terminal and network side device”. Technical Field

[0002] The embodiments of the present invention relate to the field of wireless communication technology, and in particular to a multi-mode communication method, a terminal and a network side device. Background Art

[0003] The Long Term Evolution (LTE) system has supported sidelink since the 12th release, which is used for direct data transmission between terminals (User Equipment, UE) without going through network equipment. LTE sidelink is designed for specific public safety matters (such as emergency communications in disaster sites such as fire sites or earthquakes), or vehicle to everything (V2X) communications. Vehicle to everything communications include various services, such as basic safety communications, advanced (automatic) driving, platooning, sensor expansion, etc. Since LTE sidelink only supports broadcast communications, it is mainly used for basic safety communications. Other advanced V2X services will be supported through the New Radio (NR) sidelink.

[0004] Therefore, the UE needs to support multi-mode communication on the sidelink, and support different services by enabling different modules at the same time. In addition, the sidelink multi-mode communication is also applicable when the UE is roaming in different regions or when the network is in transition between different modes.

[0005] However, since the sidelink is a half-duplex working mode, if there is a lack of coordination between the LTE sidelink and the NR sidelink multi-mode communications, it is possible that one party is sending data while the other party is receiving, resulting in a conflict between sending and receiving. On the other hand, V2X services can work on both the sidelink interface and the Uu interface (i.e., downlink and uplink) at the same time, and conflicts may also occur between the sidelink interface and the Uu interface in different modes. For example, when one side is sending sidelink data, the other side is receiving downlink data. Therefore, corresponding coordination is also required between the sidelink interface and the Uu interface in different modes. In addition, even if the timing of sending and receiving is coordinated, sending in different modes at the same time may cause signal modulation distortion, harmonics, intermodulation interference and other problems. Summary of the invention

[0006] The embodiments of the present invention provide a multi-mode communication method, a terminal and a network-side device, which are used to solve the problems of transmission and reception conflicts and / or power limitation and interference when a UE performs multi-mode data transmission and reception.

[0187] d. Interference patterns of transmissions from other signal sources on the carriers of the LTE downlink communication mode, LTE uplink communication mode, and LTE sidelink communication mode.

[0188] Step 84: The network-side device schedules the data of the terminal's LTE downlink communication mode, LTE uplink communication mode, and LTE sidelink communication mode according to the reported resource perception information, so as to select resources with less interference and lower occupancy rate to send data as much as possible to avoid interference from other signals.

The touch panel 1371 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the contact point coordinates, and then sends it to the processor 1313, receives the command sent by the processor 1313 and executes it. In addition, the touch panel 1371 can be implemented in various types such as resistive, capacitive, infrared and surface acoustic waves. In addition to the touch panel 1371, the user input unit 137 may also include other input devices 1372.

[0282] Furthermore, the touch panel 1371 may be overlaid on the display panel 1361. When the touch panel 1371 detects a touch operation on or near it, it is transmitted to the processor 1313 to determine the type of touch event. Then, the processor 1313 provides corresponding visual output on the display panel 1361 according to the type of touch event.

It executes various functions of the terminal and processes data by running or executing software programs and / or modules stored in the memory 139, and calling data stored in the memory 139, so as to monitor the terminal as a whole. The processor 1313 may include one or more processing units; preferably, the processor 1313 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 1313.

[0286] The terminal 130 may also include a power supply 1311 (such as a battery) for supplying power to various components. Preferably, the power supply 1311 may be logically connected to the processor 1313 via a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.

[0355] The embodiment of the present invention further provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, each process of the multi-mode communication method embodiment described above is implemented, and the same technical effect can be achieved. To avoid repetition, it is not repeated here. The computer-readable storage medium is, for example, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk.

[0356] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0357] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal (which can be a mobile phone, a computer, a server, an air conditioner, or a network device, etc.) to execute the methods described in each embodiment of the present invention.

[0358] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
