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: Signaling is received (or transmitted) to configure a UE with multiple transmit beams, each for receiving beam-specific DCI. A beam-specific current DCI is received at the UE (or transmitted from a network) on the transmit beam(s), including information about beam-specific previous DCIs transmitted to the UE on any of the multiple transmit beams within a predefined time window preceding a time unit in which the current DCI was received. Information about the beam-specific previous DCIs is used to determine that at least one of the multiple transmit beams has been blocked. Each of the multiple transmit beams that have been determined to be blocked is reported to (and received by) the network. In response to receiving from the UE a report indicating at least one multiple transmit beams has been blocked, the network reconfigures the UE with a different set of multiple transmit beams each for beam-specific DCI.

Abstract: A method including transmitting from a base station (BS) at least one parameter for a first type of listen before talk (LBT) procedure to be used for uplink to be received by the base station; and configuring the base station (BS) for a different second type of listen before talk (LBT) procedure for downlink from the base station (BS). A method including receiving by a User Equipment (UE) at least one parameter for a first type of listen before talk (LBT) procedure; using the at least one parameter for uplink transmission from the User Equipment (UE); and receiving data on downlink to the User Equipment (UE) during a portion of a sub frame, where the portion is less than an entire subframe.
