Abstract: A method, apparatus, and computer program product modifying the usage of control resources for data transmission by focusing on reducing overhead of the control channel in order to maximize the spectral efficiency by configuring physical resources into two parts for an allocation into control information for the first part, and data for both the first part and the second part or data for only the second part. Data allocation in the first part based is derived based on the data allocation in the second part and the control information allocation in the first part. The number of control symbols within a subframe or transmission time interval is minimized on the downlink control signaling, used mainly for downlink and uplink grant signaling, and for the uplink HARQ ACK/NACK feedback. Where overhead is not the only problem, usage of two symbols is proposed due to the limitations of radio frequency beamforming.

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: An approach is provided for cell re-selection. A notification message is generated to indicate initiation of a coverage area re-selection procedure to operate in a new coverage area from a current coverage area. The re-selection procedure is performed if an acknowledgement message is received in response to the notification message.

Abstract: This document discloses a solution for uplink transmit power control. According to an aspect, a method in a terminal device comprises: supporting at least first and second transmit power control parameter sets that are configured by an access node for uplink transmissions from the terminal device, wherein the first transmit power control parameter set is different from the second transmit power control parameter set; and receiving, from the access node, a message comprising downlink control information that schedules an uplink transmission from the terminal device, receiving an information element indicating a transmit power control parameter set of the at least first and second transmit power control parameter sets to be used for the uplink transmission from the terminal device.

Abstract: Systems, methods, apparatuses, and computer program products for determining transmission configuration indicator (TCI) state are provided. One method may include detecting, by a user equipment, one or more downlink control information (DCIs), and determining, by the user equipment, at least one of the one or more DCIs. Acknowledgement information for the determined at least one of the one or more DCIs is transmitted in a same symbol, in a same slot or in a same uplink channel. The method may also include determining, by the user equipment, a first TCI state indicated in a first DCI, where the first DCI is latest in time among the determined at least one of the one or more DCIs, and applying, by the user equipment, the first TCI state.

Abstract: Systems, methods, apparatuses, and computer program products for fast downlink beam switching assumptions related to quasi-colocation are provided. For example, a method can include determining whether a reported downlink reference signal corresponds to a reference signal, based on a spatial reception parameter corresponding to channel conditions and supporting beamforming, with a resource set that is configured to a user equipment with a tracking reference signal parameter. The method can also include interpreting a downlink reception parameter based on the determination regarding the reported downlink reference signal. The method can further include controlling at least a receive beam or a transmit beam of the user equipment based on the interpretation of the downlink transmission configuration indicator state.
