Method for Transmitting Up Link Control Signal in Mobile Communication System

Abstract

The present invention relates to a method for transmitting uplink control information in a mobile communication system; and, more particularly, to a method for effectively forming uplink control information transmitted through a downlink from a base station to a terminal in a mobile communication system for providing a packet service and transmitting the uplink control information with minimum radio resources occupied. The method includes the steps of generating uplink control information; allocating the uplink control information to a downlink-shared radio resource for packet data transmission based on downlink scheduling information; and transmitting the radio resource to a terminal. The present invention is applied to a mobile communication system.

         3 . The method of  claim 2 , wherein a predetermined part of a terminal scheduling identifier is reserved and allocated as the group identifier. 
     
     
         4 . The method of  claim 1 , wherein in the step b), the uplink control information is variably local-allocated on the downlink radio resource using the downlink scheduling information. 
     
     
         5 . The method of  claim 1 , wherein in the step b), the uplink control information is variably distributed and allocated on the downlink radio resource based on the downlink scheduling information. 
     
     
         6 . The method of  claim 1 , wherein the uplink control information includes at least one among uplink scheduling information, random access response information, and response information for sustaining uplink synchronization. 
     
     
         7 . The method of  claim 6 , wherein the uplink scheduling information includes a scheduling identifier, a radio resource block location information of the uplink control information, and an allocation period information. 
     
     
         8 . The method of  claim 6 , wherein the random access response information includes a terminal identifier and uplink radio resource block location information. 
     
     
         9 . The method of  claim 1 , wherein in the step b) the uplink control information is fixedly allocated to downlink radio resource. 
     
     
         10 . The method of  claim 9 , further comprising the step of:
 transmitting radio resource fixed allocation information of uplink control information to a terminal through a broadcasting channel (BCH).   
     
     
         11 . A method for transmitting random access response information of a mobile communication system, comprising the steps of:
 a) generating random access response information; and   b) allocating the random access response information on downlink-shared radio resource using downlink scheduling information,   wherein the downlink scheduling information includes a group identifier denoting a terminal or a terminal group to receive the random access response information.   
     
     
         12 . The method of  claim 11 , wherein the random access response information includes at least one among a terminal identifier, timing alignment information, and uplink radio resource block location information. 
     
     
         13 . The method of  claim 11 , wherein a predetermined part of a scheduling identifier is reserved and used as the group identifier. 
     
     
         14 . The method of  claim 11 , wherein in the step b), random access response information for at least one terminal is allocated to a downlink-shared radio resource. 
     
     
         15 . A method for receiving random access response information of a mobile communication system, comprising the steps of:
 a) receiving a downlink-shared radio resource; and   b) obtaining random access response information from the downlink-shared radio resource based on downlink scheduling information,   wherein the downlink scheduling information includes a group identifier denoting a terminal or a terminal group to receive the random access response information.   
     
     
         16 . The method of  claim 15 , wherein the random access response information includes at least one among a terminal identifier, timing alignment information, and uplink radio resource block location information. 
     
     
         17 . The method of  claim 15 , wherein a predetermined part of a scheduling identifier is reserved as the group identifier. 
     
     
         18 . The method of  claim 15 , wherein random access response information for at least one terminal is allocated to the downlink-shared radio resource.
