Abstract:
1. A method of determining when to perform a transport format selection procedure in a User Equipment (UE) transmitting data in a cellular radio system using an Enhanced Uplink (EUL), where the User Equipment supports Discontinuous Transmission (DTX) and Discontinuous Reception (DRX), the method comprising the steps of: (a) determining an amount of data in a transmission buffer of the UE; (b) determining whether to perform a transport format selection procedure in a next Transmission Time Interval (TTI), wherein the determination is based on the determined amount of data in the UE transmission buffer; and (c) limiting the number of consecutive TTIs used for Enhanced Dedicated Channel, E-DCH, DTX transmissions by the UE; further comprising performing the transport format selection procedure in response to determining that the transport format selection procedure should be performed, wherein the transport selection procedure comprises the steps of: (i) determining whether a maximum number of continuous transmission has been reached; and (ii) selecting a transport format after performing the step of determining whether the maximum number of continuous transmission has been reached.
