Abstract:
1. A local cognition enabling pilot channel (CPC) radio access information transmitter for use in a communications area serviced by multiple different radio access technologies (RATs) allocated to different radio resources in different locations in the communications area, where each RAT is associated with one or more RAT radio transceivers for serving user equipments (UEs) at least in some portion of the communications area using one of the multiple RATs, the local CPC radio access information transmitter being in addition to the RAT radio transceivers and located near an associated hotspot service area at least partly inside the communications area, the local CPC radio access information transmitter comprising: processing circuitry configured to: determine local CPC radio access information including one or more different RATs available for UE service in the hotspot service area and a frequency or frequencies of operation allocated to each RAT in the hotspot service area, send a registration message to a wide area CPC radio access information transmitter that is geographically separated from the local CPC radio access information transmitter and that transmits, at a sufficiently high transmit power level in order to be received over substantially all of the communications area, wide area CPC radio access information for each of multiple smaller service areas in the communications area, and that decides whether to transmit local CPC radio access information, determine if a request message is received from the wide area CPC radio access information transmitter requesting local CPC radio access information from the local CPC radio access information transmitter in addition to and different from information in the registration message, and if so, to transmit to the wide area CPC radio access information transmitter the requested local CPC radio access information from the local CPC radio access information transmitter, when the request message is not received requesting the local CPC radio access information from the local CPC radio access information transmitter, then based on a response from the wide area CPC radio access information transmitter to the registration message, determine what radio resources to use to transmit the local CPC radio access information signals, and radio transmission circuitry configured to transmit, at lower power than the high transmit power used by the wide area CPC radio access information transmitter, the local CPC radio access information for receipt by UEs in the hotspot service area using the determined radio resources, where the lower power is designed for satisfactory reception by UEs inside the hotspot service area but for less than satisfactory reception by UEs outside the hotspot service area, wherein the determined radio resources are assigned by the wide area CPC radio access information transmitter managing one or multiple local CPC radio access information transmitters in the communications area.
