Method of reporting scheduling information

Abstract

A method of encoding and transmitting information relating to data to be transmitted from user equipment to a base station in a multi-carrier wireless telecommunications network. Each carrier comprises a data channel. The method comprises the steps of: generating an indication of the characteristics of said data to be transmitted; determining an indication of estimated power available to send data on said data channel of each carrier; and encoding a scheduling information message for each carrier, said scheduling information message being generated from the indication of estimated power available to send data on said data channel of that carrier and the characteristics of said data to be transmitted. The encoded scheduling information message for each carrier is transmitted to the base station on two or more carriers.

         12 . The method according to  claim 1 , wherein said at least one carrier further comprises a pilot channel and said indication of estimated power available to send data on said data channel of said at least one carrier comprises a ratio of user equipment available power for data transmission to power pre-allocated to the pilot channel of said at least one carrier. 
     
     
         13 . The method according to  claim 1 , wherein generating an indication of the one or more characteristics of said scheduling information, determining an indication of estimated power available to send data on said data channel of said at least one carrier, encoding a scheduling information message for said at least one carrier, and transmitting said encoded scheduling information message for said at least one carrier to the base station on two or more carriers are periodically repeated. 
     
     
         14 . User equipment operable to encode and transmit scheduling information from said user equipment to a base station in a multi-carrier wireless telecommunications network, at least one carrier comprising a data channel, said user equipment comprising:
 a controller operable to generate an indication of the characteristics of said scheduling information, and determine an indication of estimated power available to send data on said data channel of said at least one carrier, wherein at least one characteristic is user equipment buffer information,   the controller being operable to encode a scheduling information message for said at least one carrier, said scheduling information message being generated from the indication of estimated power available to send data on said data channel of said at least one carrier and the characteristics of said scheduling information,   the controller being further operable to transmit said encoded scheduling information message for said at least one carrier to the base station on two or more carriers.   
     
     
         15 .
