Abstract: Various communication systems may benefit from improved handover techniques. For example, a communication system may allow for an autonomous user equipment handover operation in a licensed or unlicensed spectrum. A method may include receiving a measurement condition at a user equipment. The measurement condition may include a maximum duration of time for sending a message to a base station of a source cell. The message may inform the base station of the source cell that an autonomous handover is initiated. The method may also include initiating the sending of the message to the base station of the source cell during the duration of time Tamer to indicate of the measurement condition. In addition, the method may include commencing the autonomous handover after the duration of time of the measurement condition has expired or upon successful transmission of the message to the base station of the source cell.

Abstract: Communication systems may benefit from appropriate measurements of transmitters. For example, certain communication systems using dual connectivity may benefit from network controlled and deployment based increased primary cell measurements. A method can include configuring, by a network element, a user equipment to perform measurements on both a master cell group and a secondary cell group, according to activity in the secondary cell group.

Abstract: The monitoring of control channels, such as the physical downlink control channel, may benefit from the influence of data buffer status information. In certain embodiments, a method includes monitoring a downlink channel (for example, a PDCCH) in active time. The method also includes monitoring an instantaneous status of a data buffer related to a user equipment and/or a base station. The monitoring of the downlink channel is guided by the instantaneous status as presently known.
