Title: DEVICES, INFRASTRUCTURE EQUIPMENT AND METHODS FOR RELAY DEVICES
Abstract:
A communications device acting as a relay device (420) is configured to communicate with communications devices (430) operating with a mobile communications network and infrastructure equipment (410) forming part of the mobile communications network. The relay device (420) comprises transmitter circuitry (421) configured to transmit signals to the communications devices and to the infrastructure equipment, receiver circuitry (422) configured to receive signals from the communications devices (430) and from the infrastructure equipment (410), and controller circuitry (423). The controller circuitry (423) is configured to determine whether predetermined conditions relating to the setting of an indication bit have been met, wherein the indication bit indicates whether the relay device (420) is able to form new connections with one or more of the communications devices (430), to set the indication bit dependent on the determination of whether the predetermined conditions have been met, wherein the relay device is not able to form new connections with one or more of the communications devices (430) when the predetermined conditions are met, and to broadcast the indication bit. This technique allow for the minimising of information that needs to be broadcast over the D2D sidelink to inform communications devices (430) whether access to relay nodes (420) is barred.
