Embodiments of the present disclosure relate to a method for confirming uplink semi-persistent scheduling deactivation and a terminal device. In example embodiments, an indication of uplink semi-persistent scheduling deactivation is received from a base station while the terminal device stores data available for uplink transmission. Then, confirmation of the deactivation is sent to the base station. Such confirmation of the deactivation may notify the base station that the terminal device has received the indication of the uplink semi-persistent scheduling deactivation and further that the uplink semi-persistent scheduling will be deactivated at the terminal device.

A method, apparatus and computer program products are provided for facilitating coordinated content delivery in multicast/broadcast networks. One example method includes receiving content from a service provider during a content service period, identifying a content service break period, the content service break period characterized by a break in transmission of content from the service provider intended for user devices, fetching localized content, and causing delivery of the localized content during the content service break period, the delivery of the localized content being performed via Xcast to determine a most radio resource efficient delivery mechanism.

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.

Autonomous user equipment handover in licensed or unlicensed spectrum

Handover failure modes are identified by logging information associated with at least one of a handover failure or a radio link failure. The information identifies whether or not a user equipment was engaged in an exchange of at least one of data traffic or control traffic with a network at the time that the handover failure or radio link failure occurred. The information is stored in a non-transitory computer-readable medium, and the information is reported to the network. The information is reported using a radio link failure or connection failure information signaling message. The severity of the handover failure or radio link failure is evaluated based upon the information.
