    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: A method including, detecting, by a base station in a wireless communication system, within an RAR window, at least one of multiple first messages from a plurality of user equipments, wherein the plurality of user equipments is permitted to transmit multiple first messages within the RAR window, and wherein each first message includes a PRACH preamble; in response to receiving at least one PRACH preamble in the at least one of multiple first messages, transmitting at least one second message including an RAR downlink channel for each preamble received; receiving at least one third message, from at least one user equipment of the plurality of user equipments, including a beam connection request and transmitting at least one fourth message to the at least one user equipment on the requested beam.

    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: Embodiments of the present disclosure relate to controlling a control resource set (CORESET) #0 puncturing. Some embodiments comprise determining, at a first apparatus, based at least on detection of a synchronization signal block, received from a second apparatus, on a specific frequency location, whether a CORESET of a specific type is punctured, wherein a portion of resources punctured in the CORESET of the specific type are incapable of carrying downlink control information; in accordance with a determination that the CORESET of the specific type is punctured, obtaining a CORESET puncturing pattern; and determining the portion of resources punctured in the CORESET at least based on the CORESET puncturing pattern. Furthermore, the method comprises indicating, from a second apparatus to a first apparatus, that a CORESET of a specific type is punctured by transmitting a synchronization signal block on a specific frequency location.
