Embodiment 1

[0070] Embodiment 1 of the present invention provides a multi-time period resource indication method, which can be applied to access points and stations, for example: figure 2 The AP and STA1-STA4 in the AP, the access point and the station can support the next generation WLAN standard, for example: 802.11ax standard. image 3 is a flowchart of the resource indication method, and the specific steps are as follows:

[0071] Step 310: the access point sends a trigger frame.

[0072] Step 320: the access point receives the multi-period uplink physical layer protocol data unit PPDU.

[0073] Step 330: the access point sends an acknowledgment frame.

[0074] Specifically, the detailed structure of the trigger frame mentioned in step 310 is as follows Figure 4 As shown, the trigger frame carries a plurality of time period information fields, and each time period information field of the plurality of time period information fields includes public information and user-specific in...

Embodiment 2

[0111] Please refer to Figure 15 , is a schematic block diagram of a multi-period-based resource indication device in a wireless local area network provided by an embodiment of the present invention. The resource indication device is, for example, an access point, or a dedicated circuit or chip that implements related functions. The resource indicating device 1000 includes a processor 1010 , a memory 1020 , a baseband circuit 1030 , a radio frequency circuit 1040 and an antenna 1050 . The resource indicating means can be figure 2 AP shown in . The AP communicates with STA-STA4.

[0112] Specifically, the processor 1010 controls the operation of the resource indicating device 1000 . The memory 1020 may include read-only memory and random access memory, and provide instructions and data to the processor 1010, and the processor may be a general-purpose processor, a digital signal processor, an application-specific integrated circuit, a field-programmable gate array, or other...

Abstract

An embodiment of the present invention provides a resource indication method applied to multiple time periods, the method includes: an access point sends a trigger frame, the trigger frame carries multiple time period information fields, and each time period of the multiple time period information fields The information field contains public information and user-specific information of one or more stations; the access point receives the multi-time period uplink physical layer protocol data unit PPDU, and the multi-time period uplink PPDU includes uplink data sent by multiple stations in multiple time periods ; The access point sends an acknowledgment frame. The embodiment of the present invention also provides a corresponding resource indicating device. By applying the method and device of the embodiment of the present invention, efficient resource indication and confirmation for multiple time periods in the 802.11ax system can be realized, and the efficiency of transmitting small packet services of existing WLAN equipment can be improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a multi-time segment-based resource indication method and device. Background technique [0002] The existing wireless local area network (English: Wireless local Access Network, referred to as: WLAN) standard based on OFDM (English: Orthogonal Frequency-Division Multiplexing, Chinese: Orthogonal Frequency Division Multiplexing) technology has gradually evolved from 802.11a, 802.11n, 802.11 ac and other versions, currently the IEEE (English: Institute of Electrical and Electronic Engineers, Chinese: Institute of Electrical and Electronics Engineers) 802.11 standard organization has launched a new generation of WLAN standards called HEW (High Efficiency WLAN, high-efficiency wireless local area network) 802.11 ax standardization work, by introducing OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access) technology, 802...
