Wireless communication method and device

Abstract

The embodiment of the invention provides a wireless communication method and equipment. The wireless communication method comprises the steps that access point equipment transmits the downlink aggregate data frames of station equipment to multiple sets of station equipment at the same time slot, at least one downlink aggregate data frame includes multiple communication identifiers, the access point equipment transmits block acknowledgment request frames according to the downlink aggregate data frames of all the station equipment, and the block acknowledgment request frames are used for indicating all the station equipment to reply the block acknowledgment frames, wherein the block acknowledgment request frames include the block acknowledgment request information fields of all the station equipment, and the block acknowledgment request information fields of at least one station equipment indicate that the downlink aggregate data frames of the station equipment have multiple communication identifiers so that multiple station equipment is enabled to acknowledge the downlink aggregate data frames (A-MPDU) of multiple communication identifiers communicated in the same time period of the access point equipment in the same time period.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a wireless communication method and device. Background technique [0002] In the wireless local area network (WLAN) communication standard 802.11ac and earlier Wireless Fidelity (WiFi for short) standards, when a station (Station, short for STA) or an access point (Access Point, short for AP) sends data, it will An acknowledgment strategy for responding to the data is set in the MAC header of the data. The receiving end receiving the data responds accordingly according to the confirmation policy. [0003] In the new-generation WLAN communication standard 802.11ax, an orthogonal frequency division multiple access (orthogonal frequency division multiple access, OFDMA for short) technology is introduced. Multiple stations receive or transmit data on different sub-channels. For downlink data transmission (the AP sends data to the station), the AP uses OFDMA ...

Problems solved by technology

[0005] In the above process, the data (A-MPDU) communicated between multiple sites and the AP in the same time period can only contain one TID service. Using padding bits to ensure that the data transmitted by multiple stations is aligned in time, such a transmission method will cause waste of resources. However, for the continuous development of wireless LAN communication standards, in order to make better use of resources, it is necessary to allow multiple stations to be in the same location as the AP. The data (A-MPDU) communicated within the time period contains multiple TID services, so the confirmation process and the corresponding frame structure need to be redesigned
