Abstract:
1. A method in a mobile terminal for requesting access to a wireless communication system, comprising: receiving broadcasted system information that indicates a first available resource of a contention based channel, wherein the contention based channel is an Enhanced Dedicated Channel (E-DCH); deriving a second available resource of the same contention based channel based on the first available resource of the contention based channel; and transmitting an access request preamble mapped to the second available resource to access the wireless communication system; wherein each E-DCH resource is defined by a Fractional Dedicated Physical Control Channel (F-DPCH) code number information element, an “E-DCH Hybrid Automatic Repeat Request Acknowledgement Indicator Channel (E-HICH) info for common E-DCH” information element, and a Soffset information element that indicates a slot within the F-DPCH in which power control commands are included for the F-DPCH code number; and wherein if a Soffset information element is not received for the second available resource, the mobile terminal determines a default Soffset value for the second available resource as function of an Soffset value received for the first available resource.
