A base station, a terminal device, a control method, and a program for communication handover are provided. First information indicating one or more base stations which are candidates for a handover destination of a terminal device in connection from a base station, is acquired. Second information regarding communication quality predicted in a communication through a candidate base station for each of the candidate base stations is acquired based on the first information. Third information regarding the communication quality for at least one of the candidate base stations is notified to the terminal device based on the second information. The third information is used to handover of the terminal device.

The present invention relates to a method and apparatus for reducing power consumption in a receiver of a time slotted communication system. An RF front end has power applied after the start of a preamble or after the start of a header, or upon the start of a packet payload based on connection status, signal level, and interference level. Where the signal level is constant, the communication system is in a connected state, and the interference level is low, the system bypasses packet header destination address matching, or optionally, uses only the least significant bits of the header destination address for matching purposes.

A method and apparatus for receiving system information, a method and apparatus for sending system information, and non-transitory computer-readable storage medium are disclosed. The method for receiving system information may include: receiving system information (SI) reception indication information sent by a base station; and receiving system information indicated by the SI reception indication information.

The present invention relates to a method of transmitting a signal by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving a handover command containing configurations for a second network, from a first network; performing a random access procedure to the second network; re-establishing a packet data convergence protocol (PDCP) entity associated with a signaling radio bearer (SRB) based on the configurations for the second network, after a random access procedure to the second network successes; transmitting a radio resource control (RRC) message to the second network using the re-established PDCP entity.
