A technique for transmitting and receiving a configuration message for a phase tracking reference signal, PT-RS, on a radio channel between a radio access node and a radio device is described. The radio channel comprises a plurality of subcarriers in a physical resource block, PRB. A subset of the subcarriers in the PRB is allocated to a demodulation reference signal, DM-RS. As to a method aspect of the technique, the configuration message is transmitted to the radio device. The configuration message comprises a bit field that is indicative of at least one subcarrier allocated to the PT-RS among the subset of subcarriers allocated to the DM-RS.

The present disclosure relates to wireline communication systems, and in particular to aspects of a method and a line estimation device for estimating a characteristic impedance of a section of a transmission medium. The method comprises determining, by a test equipment having a test port with known impedance Zref, an S11 scattering parameter vector S11ref[f] of the transmission medium, indexed by frequency f. The method also comprises generating, based on Zref and S11ref[f], a model of reflection in the transmission medium corresponding to an observation of the transmission medium via a test port having a test impedance ZT, and also estimating the characteristic impedance of the section as a value of ZT which minimizes a difference between a reflection value of the model of reflection and a respective target reflection value of the section.

The invention discloses a method (400) for use in a first node (110) in a wireless access communication system (100). According to the method, the first node controls (405) traffic to and from users, UEs (120), within a certain area in the system, a cell, and the first node is equipped (410) with a plurality of transmit antennas (111,113). The first node can employ (415) a variety of multi antenna transmit modes for down link transmissions, i.e. transmissions to the UEs, and the first node can carry (420) out a so called Random Access (RA) procedure with UEs which do not have a dedicated up link resource, i.e. a resource to the eNodeB. According to the method, one and the same down link multi antenna transmit mode is used by the first node during the RA procedure.
