Embodiment Construction

[0033] As mentioned in the background art, how to perform multi-link synchronous transmission needs further research.

[0034]The applicant of the present invention has found through research that in the IEEE802.11ac protocol, the transmission with a channel bandwidth of 80+80 MHz is a non-contiguous mode transmission. In this discontinuous mode, only one 80MHz channel is the primary channel. Another 80MHz channel is a secondary channel. The auxiliary channel transmission is synchronized with the main channel transmission, and only when the main channel is available, the auxiliary channel can transmit data. This method can be regarded as the simplest synchronous multi-link system and can be compared with the old single-link system. Allow. Embodiments of the present invention extend and improve this concept, and propose a more widely applicable synchronous multi-link system.

[0035] An embodiment of the present invention provides a multi-link transmission method, including:...

Abstract

The invention discloses a multilink transmission method and device, a multilink receiving method and device, a storage medium and a terminal. the multilink transmission method comprises the steps: determining a link synchronization group which comprises a single main link and at least one auxiliary link, and enabling the at least one auxiliary link to be synchronous with the main link; and when synchronous transmission is carried out by adopting multiple links, transmitting different data packets on the main link and the auxiliary link respectively. According to the technical scheme provided by the invention, the data transmission efficiency is improved, and a feasible technical scheme is provided for multi-link synchronous transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-link transmission and reception method and device, a storage medium, and a terminal. Background technique [0002] Currently, in the traditional Institute of Electrical and Electronics Engineers 802.11 (Institute of Electrical and Electronics Engineers 802.11, referred to as IEEE802.11) protocol (for example, wireless local area network (Wireless Local Area Network, referred to as WLAN) protocol), only a single link is defined. system, the discussion of multilink systems started in the developing 802.11be, in which asynchronous transfer multilink systems, data packets can be sent over one of several supported channels. Typically, each data packet can be sent over either channel. [0003] In a multi-link system, when the isolation between two links of the same terminal is poor, the transmission of one link will seriously interfere with the reception of the ...
