METHOD AND ARRANGEMENT IN A TELECOMMUNICATION SYSTEM

摘要

The present invention relates to a method for uplink transmission in a cellular telecommunication network supporting both DFT-spread OFDM and regular OFDM as access schemes in the uplink. The method comprising the steps of: receiving a resource allocation message from the network; determining whether said resource allocation fulfills at least one predefined condition that implicitly indicates which access scheme to be used in uplink transmission; if a condition for implicit indication is fulfilled, selecting access scheme according to a pre-defined rule, applying the selected access scheme in the uplink transmission. Hereby, in case of fulfillment of any of the predefined conditions, no explicit signaling of information regarding the usage of DFT-spread OFDM or regular OFDM is required. The invention furthermore relates to a terminal capable of performing said method, a method in a network node, and a network node.
