Abstract:
1. A method in a user equipment in a telecommunication network for handling unreliable relative scheduling grants applicable in a single link and a soft handover scenario, the method comprising the steps of: detecting at least one unreliable received relative scheduling grant, where the at least one unreliable relative scheduling grant comprising one of a HOLD command, an UP command and a DOWN command, wherein the detecting step further comprises determining if at least one received relative scheduling grant has a received power on a grant channel that is within a predetermined interval and if yes then the at least one received relative scheduling grant is the at least one unreliable received relative scheduling grant; interpreting any detected unreliable relative scheduling grant as HOLD; and estimating a new serving grant based at least on the detection and the interpretation, where the new serving grant represents uplink resources to be used by the user equipment; the estimating step comprises the step of maintaining the last serving grant for which the corresponding relative scheduling grants were all reliable; and where the relative scheduling grant provides an indication to the user equipment about a maximum amount of uplink resources that may be used by the user equipment.
