1. A method for operating a wireless communication network that supports a plurality of reference signals (RS), the method comprising:
receiving, with a user equipment (UE), a first set of beamformed signals comprising at least one beamforming signal from a first transmission and reception point (TRP) using at least a first spatial reception filter; and at least a second set of beamformed signals comprising at least one beamformed signal from a second TRP using at least a second spatial reception filter;
analyzing a first channel condition between the first TRP and the UE and a second channel condition between the second TRP and the UE;
providing a measurement report indicating the first channel condition and the second channel condition; and reporting the measurement report to the wireless communication network such that the measurement report comprises a filter information indicating the first spatial reception filter and the second spatial reception filter;
determining, based on the measurement report, parameters of an uplink RS, the parameters comprising at least a characteristic of the uplink RS and a spatial information of the uplink RS; wherein the uplink RS is adapted based on a channel condition between the UE and at least the first TRP and the second TRP;
receiving, with the UE, at least one instruction signal comprising information indicating the parameters of the uplink RS;
transmitting the uplink RS with the UE;
receiving the uplink RS with the first TRP and evaluating reception of the first TRP to acquire a first evaluation result and receiving the uplink RS with the second TRP and evaluating reception of the second TRP to acquire a second evaluation result; and
determining uplink transmission links for a UE multi-TRP communication or estimating, for a positioning procedure in the wireless communication network, a position of the UE in the wireless communication network based on the first evaluation result and the second evaluation result.
