Abstract: The method includes performing at least one first monitoring of a power savings channel of a physical downlink control channel (PDCCH) for control information, the PDCCH being associated with at least one base station, the control information including a power saving downlink control information (PS-DCI) format, the control information providing an indication to start a timer for an ON duration of a discontinuous reception (DRX) cycle for a user equipment (UE) to monitor the PDCCH. The method further includes performing a random-access channel (RACH) procedure with the at least one base station based on the control information. The network node performs the method.

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).
