Abstract: A technique for assigning pilot signals to user equipments is described. The user equipments access a radio base station that provides radio access. As to a method aspect of the technique, an access burst including initial pilot signals is received from the user equipments, wherein at least two of the user equipments apply simultaneously the same initial pilot signal. A multicast channel to the at least two user equipments is estimated based on the received access burst. A combined signal power received at the radio base station is computed for the at least two user equipments based on the estimated multicast channel. A message to the at least two user equipments is sent using the multicast channel. The message is indicative of the combined signal power and assigns different pilot signals to the at least two user equipments, wherein the assignment depends for each of the at least two user equipments on the combined signal power and a signal power received at the respective user equipment.

Abstract: A wireless device, a network node and respective methods performed thereby for communicating with each other are provided. The method performed by the wireless device comprises determining (120) a first interference level indication of a first frequency resource; and determining (125) a second interference level indication of a second frequency resource. The method (100) further comprises transmitting (130) a first uplink reference signal on the first frequency resource with a first transmission power, and transmitting (135) a second uplink reference signal on the second frequency resource with a second transmission power, wherein the first transmission power is based on the first- and second interference level indications.
