Abstract

The disclosure relates to a transmission device (200) for transmitting a radio signal (202) over a radio channel. The transmission device (200) includes: a radio signal generator (201), configured togenerate a radio signal (202) in time-frequency domain; a channel state information (CSI) interface (203), configured to receive CSI (204) of the radio channel; a pilot generator (205), configured tocompose a pilot signal (206) from at least one pre-defined pilot signal, wherein a number and a location of the at least one pre-defined pilot signal in the composed pilot signal (206) is determined based on at least one of a latency requirement and / or the received CSI (204); a pilot insertion unit (207), configured to insert the composed pilot signal (206) into the radio signal (202); and a transmission unit (209) configured to transmit the radio signal comprising the inserted composed pilot signal (208). The disclosure further relates to a reception device (300) for receiving a radio signal(302) over a radio channel.

Description

technical field [0001] The invention relates to the processing of synthetic pilot signals by transmitting and receiving equipment. In particular, the present invention relates to incremental pilot configuration techniques. Background technique [0002] In mobile communication systems, due to channel impairments such as multipath echoes and Doppler effects, the receiver obtains a distorted version of the transmitted signal. The receiver needs to process the received signal according to the channel distortion knowledge to compensate the channel distortion. To gain channel knowledge, the transmitter sends training symbols known to the receiver—called pilots. The receiver uses the knowledge of the channel on the pilot and extends this knowledge to other data symbols, thereby compensating for channel effects. [0003] In current mobile communication systems such as Long Term Evolution (LTE), pilots are inserted at fixed time / frequency intervals (fixed density). These interval...
