Abstract:
In order to simultaneously perform frequency resource sensing and data transmission, a pico base station (BS) within the coverage of a macro BS may determine the number of antennas for frequency band sensing and/or the number of antennas for data transmission and reception from among a plurality of antennas of the pico BS. The pico BS may also determine the duration of the frequency band sensing in a radio frame. The pico BS could then perform frequency band sensing, for the determined duration, or data transmission and reception according to the determined number of antennas for frequency band sensing and/or the determined number of antennas for data transmission. The duration of frequency band sensing and the number of antennas for frequency band sensing and data transmission may be determined based on the data throughput of the pico BS.
