Abstract
According to some embodiments, a method for use in a frequency-hopping wireless transmitter for transmitting in unlicensed spectrum comprises: obtaining a configuration for a plurality of frequency channels in unlicensed spectrum; and transmitting a data transmission according to a frequency-hopping pattern across the plurality of frequency channels. The configuration for the plurality of frequency channels comprises a first subset of frequency channels for downlink transmission and a second subset of frequency channels for uplink transmission. The frequency channels in the first and second subsets are mutually exclusive. In some embodiments the first and second subset of frequency channels each comprise 160 frequency channels in the 2.4 GHz band, or 50 frequency channels in the 915 MHz band.
