Transmission of data block information in a cellular radio system

Abstract

A transmitter transmits a transport format indication to a receiver. Each value of the transport format indication identifies at least two transport block sizes to enable flexible use of different transport block sizes.

1 . A method of controlling a transmitter, the method comprising:
 transmitting first data comprising a transport format indication wherein at least one bit in the first data belongs to an indication of a transport format for a first transmission; and   transmitting second data comprising a transport format indication wherein at least one bit in the second data corresponding to the at least one bit in the first data indicates a scheduling type for a second, different transmission.   
     
     
         2 . A method according to  claim 1 , comprising determining that a scheduling type for a transmission is to be indicated. 
     
     
         3 . A method according to  claim 1 , wherein the at least one bit in the first and second data has multiple meanings depending on a currently applicable interpretation. 
     
     
         4 . A method according to  claim 1 , wherein the at least one bit in the first and second data comprises one or more most significant bits in the transport format indication. 
     
     
         5 . A method according to  claim 4 , wherein remaining bits in the transport format indication belong to an indication of a transport format for a transmission. 
     
     
         6 . A method according to  claim 1 , wherein the at least one bit in the second data indicates whether the transmission type is persistent scheduling. 
     
     
         7 . A method according to  claim 1 , wherein the at least one bit in the second data indicates whether the transmission type is non-persistent scheduling. 
     
     
         8 . A method according to  claim 1 , wherein the at least one in the second data indicates whether the transmission type is bundling scheduling. 
     
     
         9 . A transmitter configured to:
 transmit first data comprising a transport format indication wherein at least one bit in the first data belongs to an indication of a transport format for a first transmission; and   transmit second data comprising a transport format indication wherein at least one bit in the second data corresponding to the at least one bit in the first data indicates a scheduling type for a second, different transmission.   
     
     
         10 . A method of controlling a transmitter, the method comprising:
 transmitting an indication that a currently applicable interpretation of at least one bit in data comprising a transport format indication is to change from a first interpretation wherein the at least one bit belongs to an indication of a transport format for a transmission to a second interpretation wherein the at least one bit indicates a way of scheduling a transmission.   
     
     
         11 . A method according to  claim 10 , comprising transmitting the indication in response to determining that a scheduling type for a transmission is to be indicated. 
     
     
         12 . A method of controlling a receiver, the method comprising:
 receiving first data comprising a transport format indication wherein at least one bit in the first data belongs to an indication of a transport format for a first transmission; and   receiving second data comprising a transport format indication wherein at least one bit in the second data corresponding to the at least one bit in the first data indicates a scheduling type for a second, different transmission.   
     
     
         13 . A method according to  claim 12 , comprising interpreting the at least one bit in the first data as belonging to an indication of a transport format for the first transmission. 
     
     
         14 . A method according to  claim 12 , comprising interpreting the at least one bit in the second data as indicating a scheduling type for the second transmission. 
     
     
         15 . A method according to  claim 12 , wherein the at least one bit in the first and second data indication has multiple meanings depending on a currently applicable interpretation. 
     
     
         16 . A method according to  claim 12 , wherein the at least one bit in the first and second data comprises one or more most significant bits in the transport format indication. 
     
     
         17 . A receiver configured to:
 receive first data comprising a transport format indication wherein at least one bit in the first data belongs to an indication of a transport format for a first transmission; and   receive second data comprising a transport format indication wherein at least one bit in the second data corresponding to the at least one bit in the first data indicates a scheduling type for a second, different transmission.   
     
     
         18 . A method of controlling a receiver, the method comprising:
 receiving an indication that a currently applicable interpretation of at least one bit in data comprising a transport format indication is to change from a first interpretation wherein the at least one bit belongs to an indication of a transport format for a transmission to a second interpretation wherein the at least one bit indicates a way of scheduling a transmission; and   changing a currently applicable interpretation of the at least one bit in the data comprising the transport format indication to the second interpretation.   
     
     
         19 . A method of operating a receiver, the method comprising:
 operating the receiver in a first mode in which at least one bit in first data comprising a transport format indication is interpreted as belonging to an indication of a transport format for a first transmission; and   operating the receiver in a second mode in which at least one bit in second data comprising a transport format indication is interpreted as indicating a scheduling type for a second, different transmission, the at least one bit in the second data corresponding to the at least one bit in the first data.   
     
     
         20 . A receiver configured to:
 operate in a first mode in which at least one bit in first data comprising a transport format indication is interpreted as belonging to an indication of a transport format for a first transmission; and   operate in a second mode in which at least one bit in second data comprising a transport format indication is interpreted as indicating a scheduling type for a second, different transmission, the at least one bit in the second data corresponding to the at least one bit in the first data.
