A HIGH POWER RADIO BASE STATION, A LOW POWER RADIO BASE STATION AND RESPECTIVE METHOD PERFORMED THEREBY FOR COMMUNICATION WITH A WIRELESS DEVICE

摘要

A high power RBS and a low power RBS as well as respective methods performed thereby for communicating with a wireless device are provided. The method performed by the high power RBS comprises determining (210) transport characteristic(s) between the high power RBS and the low power RBS. When the determined transport characteristic(s) are favourable, the method comprises transmitting (220) control information to the wireless device on a first set of licensed frequency bands or on a second set of licensed frequency bands being different than the first set of licensed frequency bands. When the determined transport characteristic(s) are unfavourable, the method comprises refraining (260) from transmitting data and the control information to the wireless device on the second set of licensed frequency bands allowing the low power RBS to transmit the control information on the second set of licensed frequency bands.
