User apparatus and transmission method

Abstract

A user apparatus in a radio communication system supporting a D2D technology, includes a message generating unit configured to generate a message including a first segment and a second segment; and a message transmitting unit configured to transmit, multiple times, the message within a predetermined period, wherein information reported by a plurality of the first segments transmitted within the predetermined period by the message transmitting unit, is not changed within the predetermined period.

1 . A user apparatus in a radio communication system supporting a D2D technology, the user apparatus comprising:
 a message generating unit configured to generate a message including a first segment and a second segment; and   a message transmitting unit configured to transmit, multiple times, the message within a predetermined period, wherein   information reported by a plurality of the first segments transmitted within the predetermined period by the message transmitting unit, is not changed within the predetermined period.   
     
     
         2 . The user apparatus according to  claim 1 , wherein the message transmitting unit transmits
 control information including scheduling information of the second segment, or control information including scheduling information of the first segment and the second segment, and   the message.   
     
     
         3 . The user apparatus according to  claim 1 , wherein the message transmitting unit transmits the first segment by using a control channel, and transmits the second segment using a data channel. 
     
     
         4 . The user apparatus according to  claim 1 , wherein the message transmitting unit transmits, multiple times, the message within the predetermined period, by using a predetermined resource hopping pattern or a resource hopping pattern set from a base station in the radio communication system. 
     
     
         5 . The user apparatus according to  claim 1 , wherein HARQ soft combining is executed at another user apparatus, with respect to a plurality of the first segments transmitted within the predetermined period by the message transmitting unit. 
     
     
         6 . A transmission method executed by a user apparatus in a radio communication system supporting a D2D technology, the transmission method comprising:
 a message generating step of generating a message including a first segment and a second segment; and   a message transmitting step of transmitting, multiple times, the message within a predetermined period, wherein   information reported by a plurality of the first segments transmitted within the predetermined period at the message transmitting step, is not changed within the predetermined period.
