Embodiment Construction

[0028] As mentioned in the background, beacon frames need to be broadcast in low MCS to support multiple STAs for different purposes. As the beacon contains more and more fields, the beacon broadcast takes longer and longer.

[0029] In the prior art, beacons have some improved designs according to different purposes. For example, the TIM framework design for power saving can extract some information from the beacon and use it less frequently; the dual-beacon design of Space-Time Block Code (STBC) mode can support remote devices ; The design of short beacons and long beacons reduces the overhead of beacons, because long beacons are sent less frequently.

[0030] However, the inventors of the present application have discovered that the TIM framework is an add-on component of the beacon and is specifically designed for energy saving. No help for other uses, such as channel scanning. Dual beacons with additional STBC beacons are specifically designed for longer Basic Service ...

Abstract

A beacon sending and receiving method and device, storage medium, and terminal. The beacon sending method includes: determining the number of beacon layers, the number of beacon layers is greater than or equal to 2; determining the content of the first layer of beacons, the first The contents of layer beacons include at least required fields, and the required fields are used for all receiving devices to perform channel scanning or time synchronization; determine the contents of other layer beacons, and the contents of other layer beacons include extended fields; The content of layer beacons and the contents of other layer beacons are sent out at different times. The technical scheme of the invention can reduce the time occupied by beacon broadcasting, and improve the efficiency of beacon broadcasting and receiving.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a beacon sending and receiving method and device, a storage medium, and a terminal. Background technique [0002] In IEEE802.11, a low modulation and coding scheme (Modulation and Coding Scheme, MCS) is used to broadcast a beacon (beacon) signal. [0003] As the amendment expands the fields of the beacon, the content of the beacon becomes larger and larger, and the overhead of the beacon increases. In version 802.11-2016, 68 elements are defined for the beacon frame body. There are 86 elements defined in version 802.11ax D4.3. For the ongoing 802.11TGbe standard development, several improvement topics are considered and the beacon size will be further increased. For example, in a system supporting multi-link transmission, a beacon in one channel may also carry information on other channels. [0004] However, beacon frames need to be broadcast in low MCS...
