Abstract: Embodiments of the present disclosure relate to secondary cell activation. A method comprises transmitting, from a first apparatus and on a serving cell in an active status, a MAC layer command for activating at least one secondary cell to a second apparatus, the MAC layer command indicating a configuration on a procedure for activating the at least one secondary cell. The method further comprises receiving an acknowledgement for the MAC layer command from the second apparatus. The method further comprises causing the second apparatus to synchronize, based on at least the configuration and the acknowledgement, with the first apparatus on the at least one secondary cell. As such, the time for activating a Scell can be greatly shortened.

Abstract: A technique may include controlling downlink transmission of an uplink grant for one or more uplink data transmissions by a communication device. The uplink grant identifies one combination from a set of predetermined combinations of one or more transmission time intervals and one or more uplink reference signal transmissions, including at least one combination of two or more transmission time intervals and one or more uplink reference signal transmissions. The technique may also include using the one or more uplink reference signal transmissions of the identified combination to assist the recovery of data from the one or more uplink radio data transmissions by the communication device in the one or more transmission time intervals of the identified combination.

Abstract: A base station in a wireless network receives, from a UE in the wireless network, a message indicating the UE requests a gap for the UE to perform self-calibration of full-duplex communication. The base station determines the gap for the UE to use to perform the self-calibration of full duplex communication and sends indication of the gap toward the user equipment. The UE sends a message indicating the UE requests a gap in order for the UE to perform self-calibration of full duplex calibration. The UE receives, from the base station, indication of the gap. The UE performs the self-calibration of full duplex calibration using the gap.

Abstract: Various communication systems may benefit from appropriate coordination of measurements for mobility or other reasons. For example, Long Term Evolution communication systems may benefit from signaling for uplink short transmission time interval transmissions. A method can include determining how a user equipment is to transmit with respect to a demodulation reference signal. The method can also include providing uplink grant to schedule the user equipment to transmit according to the determination.
