COMMUNICATIONS IN A WIRELESS SYSTEM

摘要

Methods and apparatuses for extending signalling coverage are disclosed. Control information is transmitted within a coverage area of an access point. At least one first device within the coverage area is configured to retransmit the control information to at least one second device. When the first device receives a response from at least one second device that would be reachable by an adjustable coverage area but not receiving the control information directly from the access point, it transmits the response to the access point. After the access point receives an indication of at least one such second device that would be reachable by the adjustable coverage area, it can control the adjustable coverage area to provide wireless access for the at least one second device.
