Claim 0:
1. A method in a communication system in which a user equipment may communicate wirelessly with a radio base station, wherein a number of scheduling requests that the user equipment will repeatedly transmit on a dedicated uplink control channel in relation to data while not having been granted uplink resources is limited by:
monitoring, in the user equipment, whether a threshold value representing a maximum limit has been reached, characterized by a step of initiating, in the user equipment, a random access transmission on a random access channel in response to said threshold value having been reached;
initiating, in the user equipment, a measure used for limiting the number of transmitted scheduling requests;
checking, in the user equipment, whether the measure has reached the threshold value;
when no uplink resources have been granted and the measure has reached the threshold value: transmitting, by the user equipment, the random access transmission on the random access channel;
determining, by the radio base station, whether the user equipment has access to dedicated uplink control channel resources for transmission of the scheduling request, wherein the radio base station has received the random access transmission from the user equipment; and
sending, by the radio base station, a power control command to the user equipment in response to determining that the user equipment has access to the dedicated uplink control channel resources for the transmission of the scheduling request.
