Abstract: An apparatus for a terminal has means for storing a first configuration for measurement reporting on downlink reference signals, wherein one or more downlink reference signals correspond to one of a plurality of states for a first channel. The apparatus also has means for receiving an activation of a first state of the plurality of states for the first channel, and determining a second configuration for measurement reporting based on the first configuration for measurement reporting and the received activation of the first state, wherein the second configuration for measurement reporting configures the terminal to report measurements on a first downlink reference signal corresponding to the first state.

Abstract: Systems, methods, apparatuses, and computer program products for supporting a narrow serving beam in a hierarchical beam configuration. For example, certain embodiments may provide a UE that may receive, from a network node, information of a quasi co-location (QCL) configuration of self-contained, aperiodic, and/or semi-persistent tracking reference signals (TRSs) for sub-beams, where a source for one or more TRSs may be channel state information (CSI-RS) without repetition. In addition, the UE may determine these TRSs as self-contained, for which there are no associated periodic TRSs, if there is a TRS configured for an SSB sub-beam.

Abstract: A radio network element includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the radio network element to: configure a quasi-co-location-type information entry included in a transmission configuration indication state (S604) for a downlink transmission beam between the radio network element and a user equipment based on at least one beam report, the at least one beam report including at least one transmission parameter for the downlink transmission beam, and the quasi-colocation-type information entry being indicative of one or more sources of inter-beam-interference on the downlink transmission beam at the user equipment; and transmit the transmission configuration indication state including the quasi-co-location-type information entry to the user equipment (S606).

Abstract: The specification and drawings present methods and apparatuses for feedback signaling for beamforming purposes in a multiple input-multiple output (MIMO) radio environment. According to an embodiment of the invention, a mobile device is configured to measure an integer number P of different beam groups, each group representing one or more transmit beams and each group corresponding to one or more antenna ports at the mobile device. The mobile device is triggered according to the configuration to provide feedback. The radio access node transmits reference signals on each of the transmit beams across all of the groups for measurement by the mobile device and receives the triggered feedback including, for each of the different beam groups, at least one best match between a transmit beam of the respective group and a corresponding antenna port and an indication of measurement results for the best match.

Abstract: Various communication systems may benefit from improved signaling. For example, communication systems may benefit from sending a multi-numerology reference signal that allows a receiving user equipment to perform simultaneous beamforming training, and channel estimation or channel state information acquisition. A method may include receiving at a user equipment a multi-numerology joint reference signal (610). The reference signal may include a reference signal for data channel demodulation or channel state information acquisition, and beamforming training. The method may also include performing simultaneous beamforming training and channel estimation or channel state information acquisition based on the multi-numerology joint reference signal (620).
