Miscellaneous improvements on the hrpd system

Abstract

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, inclusion 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.

1 . A method for providing control information to a terminal in a multi-carrier mobile communication system, the method comprising transmitting a control message to the terminal, the message comprising a plurality of at least four consecutive fields, wherein the exclusion of or a specific value of a first of the plurality of at least four consecutive fields allows the exclusion of the following three consecutive of the plurality of at least four consecutive fields such that the length of the message is reduced. 
     
     
         2 . The method of  claim 1 , wherein the exclusion of or a specific value of the first of the plurality of at least four consecutive fields allows the exclusion of a fifth of the plurality of at least four consecutive fields such that the length of the message is reduced.

         7 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises SchedulerTag. 
     
     
         8 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises SchedulerTag, AuxDRCCoverIncluded and AuxDRCCover. 
     
     
         9 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises NumUniqueTrafficMACIndexes, AuxDRCCoverIncluded and AuxDRCCover. 
     
     
         10 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises NumUniqueTrafficMACIndexes, SchedulerTag, and AuxDRCCover. 
     
     
         11 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises NumUniqueTrafficMACIndexes, SchedulerTag and AuxDRCCoverIncluded. 
     
     
         12 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises NumUniqueTrafficMACIndexes and SchedulerTag. 
     
     
         13 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises NumUniqueTrafficMACIndexes and AuxDRCCoverIncluded. 
     
     
         14 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises NumUniqueTrafficMACIndexes and AuxDRCCover. 
     
     
         15 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises SchedulerTag and AuxDRCCover. 
     
     
         16 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises SchedulerTag and AuxDRCCoverIncluded. 
     
     
         17 . The method of  claim 1 , wherein the plurality of at least four consecutive fields comprises AuxDRCCoverIncluded and AuxDRCCover. 
     
     
         18 . The method of  claim 1 , wherein the message is a TCA message.
