First Claim
Patent Images
1. A method for handing over communications in a wireless network, comprising:
- receiving wireless communications service from a source base station;
receiving multiple assigned uplink control channels for transmitting schedule request signals to a plurality of target base stations; and
transmitting a scheduling request to a selected target base station of the plurality of target base stations over at least one of the assigned uplink control channels.

Abstract
Systems and methodologies are described that facilitate handing over mobile device communications in a wireless network from a source base station to a target base station without using a random access channel (RACH). In this regard, the mobile device can monitor multiple base stations determining timing information related thereto and access scheduling request channels for the base stations. When ready for handover, the mobile device can request data resources over the scheduling request channel using the appropriate timing information.
