Receiver and method for estimating large-scale channel properties
First Claim
1. A method performed by a receiver for estimating first large-scale channel properties associated to a first channel of a first transmitter and second large-scale channel properties associated to a second channel of a second transmitter, the method comprising:
- receiving a first signal transmitted by the first transmitter and further receiving at least a second signal transmitted by the second transmitter, wherein the first transmitter and the second transmitter are synchronised to a common synchronisation reference, and wherein the first signal comprises a first reference signal and the second signal comprises a second reference signal;
jointly estimating the first large-scale channel properties and the second large-scale channel properties based only on the first reference signal; and
associating the jointly estimated large-scale channel properties to the first channel associated to the first transmitter and to the second channel associated to the second transmitter,wherein the associated jointly estimated large-scale channel properties are exploited to perform demodulation of data transmitted by the first transmitter and the second transmitter, and wherein the demodulation of the data transmitted by the first transmitter and the second transmitter is performed using the first reference signal.

Abstract
A receiver and a method performed by the receiver for estimating first large-scale channel properties associated to a first channel of a first transmitter and a second large-scale channel properties associated to a second channel of a second transmitter are provided. The method includes receiving a first signal transmitted by the first transmitter and further receiving at least a second signal transmitted by the second transmitter. The first and the second transmitter are synchronized to a common synchronization reference, and the first signal and/or the second signal includes at least one reference signal. The method further includes jointly estimating the first and second large-scale channel properties based on the at least one reference signal, and associating the jointly estimated large-scale channel properties to the first channel associated to the first transmitter and to the second channel associated to the second transmitter.

8. A receiver adapted to estimate first large-scale channel properties associated to a first channel of a first transmitter and second large-scale channel properties associated to a second channel of a second transmitter, the receiver comprising:
-
a receiving unit adapted to receive a first signal transmitted by the first transmitter and further to receive at least a second signal transmitted by the second transmitter, wherein the first transmitter and the second transmitter are synchronised to a common synchronisation reference, and wherein the first signal comprises a first reference signal and the second signal comprises a second reference signal; an estimating unit adapted to jointly estimate the first large-scale channel properties and the second large-scale channel properties based only on the first reference signal; an associating unit adapted to associate the jointly estimated large-scale channel properties to the first channel associated to the first transmitter and to the second channel associated to the second transmitter; and a demodulation unit adapted to exploit the associated jointly estimated large-scale channel properties to perform demodulation of data transmitted by the first transmitter and the second transmitter, wherein the demodulation of the data transmitted by the first transmitter and the second transmitter is performed using the first reference signal. - View Dependent Claims (9, 10, 11, 12, 13)
