1. :
- A method performed in a network node for allocating and transmitting Mobility Reference Signals (MRS) for a wireless communication device to measure beam signal quality in a wireless communication network, the method comprising;
obtaining information on one or more of a frequency diversity, a time diversity of a channel between the network node and the wireless communication device, an antenna spatial diversity of the wireless communication device;
selecting an MRS pattern out of a set of candidate patterns based on the obtained information, wherein the candidate patterns differ from one another by one or more of their density in time and density in frequency, and by one or more of their temporal duration and frequency range;
signalling the selected MRS pattern to the wireless communication device; and
transmitting the MRS according to the selected MRS pattern,wherein selecting the MRS pattern comprises;
allocating MRS resources over a frequency span in accordance with the richer the frequency diversity, the more dense the allocation of MRS resources over the frequency span; and
allocating MRS resources over a time span in accordance with the richer the temporal diversity of the channel between the network node and the wireless communication device, the more dense the allocation of MRS resources over the time span.

Abstract
There is provided a method and a network node for allocating and transmitting Mobility Reference Signals, MRS, for a communication device to measure beam signal quality in a wireless communication network. The network node obtains information on one or more of a frequency diversity, a time diversity of a channel between the network node and the communication device, an antenna spatial diversity of the communication device. The network node selects an MRS pattern out of a set of candidate patterns based on the received information, signals the selected MRS pattern to the communication device and transmits the MRS according to the selected MRS pattern.
