Apparatus and methods for communication

摘要

In radio communication networks, such as the Long Term Evolution (LTE) or the LTE-Advanced (LTE-A) of the 3rd Generation Partnership Project (3GPP), a user equipment (UE) may communicate with another UE via a base station. UEs may also communicate directly with each other by applying resources dedicated by the network for a device-to-device (D2D) direct communication. One part of device-to-device (D2D) communication is discovery to find other interesting peers (in general a peer can mean an application, user, service, device, etc.) in proximity. The discovery can be implemented either using the direct radio signals between the devices or it may utilise network side in the process. The same discovery process may be utilised in relation to small cells. A system information block SIB comprising information on small cell discovery and D2D is generated. Any change in the SIB is indicated in a paging message. The UE receiving the paging message is thereby requested to also receive the related SIB to apply the changed information.
