Abstract:
1. A method in a radio base station for handling a timing of uplink transmissions from a user equipment to the radio base station in a radio communications network, in which the user equipment is served in a cell controlled by the radio base station, and in which cell communications are organized in radio frames comprising subframes, the method comprising: receiving a first uplink transmission from the user equipment in a subframe related to the radio base station; estimating a time parameter value based on a distance between the user equipment and the radio base station when the first uplink transmission is transmitted from the user equipment; setting a time value in a message, which time value is to be used to set a timing of a second uplink transmission at the user equipment, and which time value is based on the estimated time parameter value and a time offset value for increasing a time budget for processing in the radio base station; and transmitting the message comprising the time value to the user equipment.
