When a non-access stratum (NAS) message is generated in an NAS layer of a user equipment, the NAS layer transfers the NAS message and type information to an access stratum (AS) layer of the user equipment. An AS message containing the NAS message is transmitted to a network. The type information indicates whether the NAS message is a first type message containing user data or a second type message without user data.

A communication device may, in response to a wireless link via the first wireless interface being established with a terminal device while the communication device is a parent station state, receive a predetermined signal from the terminal device via the second wireless interface. If the predetermined signal is received from the terminal device, shifting communication device from the parent station state to a specific state where the communication device does not operate as a parent station. The communication device is maintained in the parent station state if the predetermined signal is not received from the terminal device even if the wireless link via the first wireless interface has been established with the terminal device. After shifting the communication device to the specific state, establishing a first wireless connection via the second wireless interface with the terminal device so as to participate in a second wireless network as a child station.

The present technology relates to a receiving apparatus and a data processing method that can execute delay compensation with more simplified configuration.

A receiving apparatus has a delay compensation block configured to delay, on the basis of time information included in a packet to be transmitted for each of a plurality of transmission paths including a broadcasting path, another packet to be transmitted by other transmission path than the reference transmission path with respect to a reference packet to be transmitted by a reference transmission path among the plurality of transmission paths to compensate a delay between the packets to be transmitted for each of the plurality of transmission paths. The present technology can be applied to television receivers having a channel bonding function, for example.

The disclosure concerns a method for selecting an antenna of a communication device for exchanging data with a radio access node. In order to select which one of the antennas connected to the communication device should be used to communicate with the radio access node, detection mechanisms based on resistivity measurements are run by the communication devices. However, such detection mechanisms are not reliable for detecting the connection of capacitive antennas. According to an embodiment of the disclosure, an antenna is selected for exchanging data with the radio access node upon detection of the establishment of a radio connection between said antenna and said radio access node, said detection being triggered when it is determined that the said antenna provides a better reception of the radio signals than other antennas.
