Abstract:
1. A method for allocating a group identifier, comprising: dividing all group identifies (GIDs) into N parts according to a quantity of the GIDs; and respectively allocating the N parts of the GIDs to N basic service set (BSS) networks, which communicate in a multi user-multiple input multiple output (MU-MIMO) mode, wherein the N BSS networks have a common area, N is a natural number which is greater than 1; wherein, the dividing all the GIDs into the N parts according to the quantity of the GIDs, and respectively allocating the N parts of the GIDs to the N BSS networks, which use the MU-MIMO communication mode, comprises: acquiring a number of times of communicating in the MU-MIMO mode in a preset time period by the N BSS networks; acquiring a probability of communicating in the MU-MIMO mode by each BSS network by dividing a number of times of communicating in the MU-MIMO mode by each BSS network by the number of times of communicating in the MU-MIMO mode by the N BSS networks; obtaining a quantity of GIDs allocated to each BSS network by multiplying the probability of communicating in the MU-MIMO mode by each BSS network with a total number of GIDs in the MU-MIMO mode; dividing all the GIDs into the N parts according to the quantity of the GIDs allocated to each BSS network; and respectively allocating the N parts to the N BSS networks.
