Abstract

A method for taking measurements with a smart antenna in a wireless communication system having a plurality of STAs begins by sending a measurement request from a first STA to a second STA. At least two measurement packets are transmitted consecutively from the second STA to the first STA. Each measurement packet is received at the first STA using a different antenna beam. The first STA performs measurements on each measurement packet and selects an antenna beam direction based on the measurement results.

Claims10

Dependent claims

A method for beam selection, the method comprising:

receiving a first measurement packet using a first receive beam, wherein the first measurement packet comprises a first antenna identity and a first sequence number;
performing a measurement associated with the first measurement packet;
changing the first receive beam to a second receive beam after receiving the first measurement packet and before receiving a second measurement packet;
receiving the second measurement packet using the second receive beam, wherein the second measurement packet comprises the first antenna identity and a second sequence number;
performing a measurement associated with the second measurement packet;
selecting a transmit beam based on the measurements.
