Classification: CPC H | IPC H

Claim 16:
17. A method of operating an access node of a communications network, the method comprising:
transmitting at least one downlink control message to a wireless communication device, the at least one downlink control message being indicative of a frequency density of uplink reference signals, the uplink reference signals being for an estimation of a radio channel between the wireless communication device and the communications network to coherently decode data signals encoding data of uplink data transmission, the uplink reference signals and the data signals using the same precoding,
receiving the uplink reference signals on the radio channel using a time-frequency resource mapping set in accordance with the frequency density, the time-frequency resource mapping allocating time-frequency resource elements of a plurality of time-frequency resource elements of a time-frequency resource grid of the radio channel to the uplink reference signals, and
determining a setting of a coverage enhancement parameter used for the uplink data transmission in a correlated manner with said determined of the frequency density, wherein the coverage enhancement parameter comprises at least one of a redundancy repetition count of the data of an uplink data transmission in time domain and/or frequency domain, or a code rate of the data of the uplink data transmission.
