Abstract: Methods and apparatus, including computer program products, are provided for control channel monitoring. In some example embodiments, there may be provided a method that includes receiving, at the user equipment, an indication of a codepoint activation, wherein the codepoint activation indicates that a transmission configuration indicator state being activated is associated with a second physical cell identifier different from a first physical cell identifier of a serving cell of the user equipment; and in response to the transmission configuration indicator state being activated in association with the second physical cell identifier, suspending control channel monitoring of at least one set of core resources associated with the first physical cell identifier of the serving cell of the user equipment. Related systems, methods, and articles of manufacture are also disclosed.

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: There are provided measures for improved beam indication. Such measures exemplarily comprise storing at least one beam determination entry, wherein each of said at least one beam determination entry is indicative of a respective first beam and at least one respective second beam narrower than said first beam and at least partially in quasi co-location with said first beam, receiving indicator information indicative of one of said at least one beam determination entry, and selecting, for a predetermined physical channel, a transmission beam out of said first beam and said at least one second beam of said indicated one of said at least one beam determination entry based on receiving power measurement results in relation to said first beam and said at least one second beam of said indicated one of said at least one beam determination entry.

Abstract: Various communication systems may benefit from appropriate designation of communication mechanisms. For example, fifth generation communication systems may use refinement beam index beam identifier association. A method can include determining, by an access node, an association between at least one reported refinement beam index and at least one logical beam index based on reception of a refinement beam index report. The method can also include providing the association to a user equipment.

Abstract: When a time domain collision between Tracking Reference Signal (TRS) symbols and downlink shared data channel symbols is detected, the TRS symbols may be multiplexed with the downlink shared data channel symbols from multiple Transmission Reception Points (TRPs) not sharing quasi co-location (QCL) parameters with each other. If a time domain collision between TRS symbols and dynamically or semi-static (e.g., persistent) downlink shared data channel transmissions is detected, transmission and/or reception of the TRS and/or the downlink shared data channel may be adjusted.

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.
