Method and device for allocating group identification

Abstract

Embodiments of the present invention discloses a method and apparatus for assigning group identification, capable of non-AP in a plurality of BSS network areas covered? STA allocates non-conflicting GIDs, reduced to non-AP? A conflict issue that occurs when the STA allocates a GID. One embodiment of the present invention provides a method comprising: dividing all groups of identification GIDs into N parts according to the number of N, respectively assigned to N using a multi-user multi-input multiple output mode MU_MIMO communication of the basic set of services BSS network use, the N BSS network exists in a public area, N is a natural number greater than 1; An access point AP in a BSS network from the group id assigned to the BSS network in the order of presets for the endpoints in the BSS network non-AP? The STA assigns a group ID.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for allocating group identifiers. Background technique [0002] In the Institute of Electrical and Electronics Engineers (IEEE, Institute of electrical and electronics engineers) 802.11ac protocol, it is stipulated that a basic service set (BSS, Basic Service Set) is composed of stations (STA, Station) that have a certain association within a certain coverage area. In the BSS network, there is only one central station with full-time management of the BSS called access point (AP, AccessPoint), while in the BSS network the stations other than the AP are called terminals, also called non-APSTA. [0003] In a BSS network, the group identifier (GID, GroupID) of the non-APSTA is assigned by the AP in the BSS network. When the AP performs multi-user multiple-input multiple-output (MU-MIMO, MultiUser-MultipleInputMultipleOutput) transmission, the same ...

Problems solved by technology

But when a non-APSTA belongs to two BSS networks at the same time (the two BSS networks are BSS1 and BSS2 respectively, the access point in BSS1 is AP1, and the access point in BSS2 is AP2), if the non-APSTA belongs to one of the BSS1 networks When grouping, AP1 assigns a GID to the non-APSTA. Since BSS2 does not know the GID assigned by BSS1 when assigning the GID, there may be a situation where the GID assigned by BSS2 is the same as the GID assigned by BSS1. For non-APSTAs of two BSS networks, GID conflicts still exist
