Abstract

The present invention concerns a method and an arrangement in a first node in a wireless communication system. The first node is using a frame structure of a Time Division Duplex mode (TDD mode) physical layer protocol for transmitting a signal from the first node to a second node in a wireless communication network. The method is characterised by the step of Transmitting a Sounding Reference Signal (SRS) in an Uplink Pilot Timeslot comprised within the TDD mode frame structure. Further, the present invention concerns a method and an arrangement in a second node in a wireless communication system.
