Abstract
In a UMTS network in which a single user can transmit or receive a number of services having different transmission power requirements over a single channel, a method of determining for each service the number of bits to be punctured or repeated to provide rate matching by the steps of deriving for each service the Energy per Bit per Noise density E /N required to achieve a desired Bit Error Rate; from each E /M deriving a value of the Energy per coded Symbol per Noise density E /N ; and from E /N deriving a rate matching factor by which that E /N can be matched to the minimum Energy per coded Symbol per Noise density applicable to the channel in which to the services are multiplexed. The values of E /N are stored in a look up table in the BTS and each mobile; the BSC generates values of semi static rate matching factors and spreading factors for each service and transmits them to the BTS and mobiles so that the mobile can calculate from the received values and the values stored in the look up table the number of bits to be punctured or repeated.
