Embodiment 1

[0074] Embodiments of the present invention provide a resource indication method, such as figure 1 shown, including:

[0075] 100. The access point generates resource mapping information.

[0076] Wherein, the resource mapping information may be MAP information, and the resource mapping information includes multiple mapping segments, each mapping segment is associated with a frame type and each mapping segment contains multiple resource indications, and each resource indication is used to indicate , the resource indicates the resource allocated to a station in the frame corresponding to the frame type associated with the mapping segment to which it belongs.

[0077] Specifically, the multiple mapping segments included in the MAP information may be arranged in the MAP information in a preset order, and the station will also read the multiple mapping segments included in the MAP information in accordance with the preset order , so that the access point does not need to spend e...

Embodiment 2

[0199] Embodiments of the present invention provide a resource indication method, taking the access point indicating to the station the resource of the downlink frame to be sent as an example, such as figure 2 As shown, the method includes:

[0200] 101. The access point counts the number of first-type downlink frames to be sent to N stations, the first-type downlink frame is one of the M-type downlink frames, and the M-type downlink frames include at least a response frame, N> 0, M>0.

[0201] 102. The access point determines a mapping segment of the first type of downlink frame according to the number of the first type of downlink frame, where the mapping segment is used to indicate resources used by the access point when sending the first type of downlink frame.

[0202] 103. Repeat steps 101 and 102 until the access point obtains M mapping segments corresponding to M types of downlink frames, and generates downlink resource mapping information (ie, downlink MAP informati...

Embodiment 3

[0325] Embodiments of the present invention provide a resource indication method, such as Image 6 As shown, the method includes:

[0326] 501. The access point counts the number of first-type downlink frames to be sent to N stations, the first-type downlink frame is one of the M-type downlink frames, and the M-type downlink frames include at least a response frame, N> 0, M>0.

[0327]502. The access point determines a mapping segment of the first type of downlink frame according to the number of the first type of downlink frame, where the mapping segment is used to indicate resource information used when the access point sends the first type of downlink frame.

[0328] 503. Repeat steps 501 and 502 until the access point obtains M mapping segments corresponding to M type downlink frames, and generates downlink MAP information according to the M mapping segments, and the downlink MAP information is used to instruct the access point to send M type Information about resources ...

Abstract

The embodiment of the invention provides a resource indication method and device, which relate to the field of communication, solve the problem that the expenditure for an access point to carry out resource indication on each station is large, and improve the resource utilization rate of resource indication. According to the scheme, the method comprises the steps: 1, the access point generates resource mapping information, wherein the resource mapping information comprises a plurality of mapping segments, each mapping segment is associated with a frame type, each mapping segment comprises a plurality of resource indications, and each resource indication is used for indicating a resource allocated to a station in a frame corresponding to the frame type associated with the mapping segment towhich the resource indication belongs; and the access point sends the resource mapping information.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource indication method and device. Background technique [0002] At present, multi-user transmission has become a hot spot in the development of wireless local area networks, such as MU-MIMO (Multi-User Multiple Input Multiple Output, multi-user multiple input multiple output) system and OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access Access) system, due to the introduction of multi-user transmission mode, in order to ensure effective communication between multiple sites and access points (AP, Access Point) using specified resource blocks, the access point provides resource instructions to each site Expenses increased dramatically. [0003] Exemplary, such as figure 1 As shown, the access point performs resource indication for the users / user groups in the station one by one, so as to instruct the station to send a MAC (...
