More Information
Summary:Mechanisms for improving the proposed high rate packet data (HRPD) system are provided. Approaches proposed are including PilotGroupID in the sector parameter message to convey the pilot group information, encoding to enable shortened NeighborList messages, improvements on RoutUpdateRequest message for request updates on multiple carriers, inclusive of the channel record of the reference pilot in the RouteUpdate message when the message sent in the connected state, using pilot drop timer of a Candidate Set pilot as a trigger for sending RouteUpdate, encoding the TrafficChannelAssignment message to shorten the message in certain situations, limiting the usage of auxiliary DRC cover in some situations to avoid confusion in determining the serving sector and processing OverheadMessages. Updated Indication and OverheadMessagesNeighborList Initialization in the idle state.
