Embodiment Construction

[0080] In order to achieve the above and other objects, the present invention relates to a method in a transmitting node, and to a corresponding method in a receiver node. According to the invention, the method in a transmission node comprises the steps of: generating at least one first receiver-specific demodulation reference signal (PDSCH-DMRS) associated with a receiver-specific data channel signal (PDSCH); generating at least one second receiver-specific demodulation reference signal (e-PDCCH-DMRS) associated with a receiver-specific control channel signal (e-PDCCH); the associated second receiver-specific demodulation reference signal (e-PDCCH-DMRS) concurrently transmitting the receiver-specific control channel signal (e-PDCCH); and concurrently transmitting the associated first receiver-specific demodulation reference signal (PDSCH-DMRS) the Receiver specific data channel signal (PDSCH). Concurrency should be interpreted in the text as "at the same time".

Abstract

The invention relates to a method in a transmitting node and to a corresponding method in a receiver node for generating and transmitting a demodulation reference signal. Said method in said transmitting node comprises the steps of: generating at least one first receiver-specific demodulation reference signal (PDSCH-DMRS) associated with a receiver-specific data channel signal (PDSCH); generating at least one A second receiver-specific demodulation reference signal (e-PDCCH-DMRS) associated with the receiver-specific control channel signal (e-PDCCH); associated with said second receiver-specific demodulation reference signal (e-PDCCH) -PDCCH-DMRS) concurrently transmits said receiver-specific control channel signal (e-PDCCH); and concurrently transmits said receiver-specific demodulation reference signal (PDSCH-DMRS) with said associated first receiver-specific The data channel signal (PDSCH). Furthermore, the present invention also relates to a transmission device, a receiver device, a computer program, and a computer program product thereof.

Description

technical field [0001] The invention relates to a method for generating and transmitting a demodulation reference signal, and a corresponding method in a receiver node. Furthermore, the invention also relates to a transmission device, a receiver device, a computer program and a computer program product thereof. Background technique [0002] In a cellular communication system, downlink (downlink, DL) means the transmission of a synchronization signal from a base station (eg, eNB) to a mobile user (eg, UE). In the uplink (uplink, UL), the transmission direction is reversed. [0003] The DL of the LTE cellular communication system is based on Orthogonal Frequency Division Multiplexing (OFDM) transmission, and both time and frequency resource units are used for information transmission. The OFDM signal comprises a set of complex sinusoids, called sub-carriers, whose frequencies are consecutive integer multiples of the fundamental (lowest non-zero) sub-carrier frequency, where ...
