Abstract:
1. A method for transmitting a message in a communications system with configured carrier aggregation of multiple component carriers, the method comprising the following steps: receiving control signalling allocating a resource on an air interface, generating a message for reporting a channel quality of the communication system for multiple component carriers, the message comprising: a first channel quality field consisting of a known number of bits, and a second channel quality field consisting of a variable number of bits, wherein the number of bits and structure of the second channel quality field is indicated by the content of the bits of the first channel quality field; and transmitting the message on the allocated resource, wherein the first channel quality field consists of a number of sub-fields, wherein each sub-field is associated to a respective component carrier and wherein the number of sub-fields is defined by the number of component carriers available for communication between a base station and a communication terminal, the size of the respective sub-fields of the first channel quality field depends on a reporting mode out of a plurality of channel quality reporting modes used for a respective component carrier, and the second channel quality field is divided into a number of sub-fields, wherein the size of each sub-field of the second channel quality field depends on a reporting mode out of the plurality channel quality reporting modes used for the component carrier associated to the respective sub-field of the second channel quality field.
