Method and network device for enabling MIMO station and SISO station to coexist in wireless network without data collision
First Claim
1. A method of enabling a multi-input multi-output (MIMO) station and a single input single output (SISO) station to coexist in a wireless network, the method comprising:
- receiving information pertaining to a station when the station accesses a wireless network;
setting coexistence information by comparing a number of antennas of the station accessing the wireless network with a number of antennas of a plurality of stations constituting the wireless network; and
transmitting a first frame containing the coexistence information to the plurality of stations constituting the wireless network.
