2. Description of the Related Art
Communication systems are used to convey information from one location to another. Different types of communication systems are known including wired and wireless systems. Wired systems include local area networks (LANs), metropolitan area networks (MANs), wide area networks (WANs), and other types of networks. Wireless systems include cellular telephone systems, satellite communication systems, and other wireless networks.
Communication systems typically include at least one device referred to as a source and at least one device referred to as a destination. A source is any device that is capable of conveying information, while a destination is any device that is intended to receive the information conveyed by the source. A communication system may include a plurality of additional devices such as repeaters, relay stations, and other similar devices. Examples of communication systems include telephone systems, cable communication systems, and wireless communication systems.
One type of wireless communication system is a radio communication system. Radio communication systems include, for example, cellular telephone systems, cordless telephones, wireless local area networks (WLANs), wireless personal area networks (WPANs), and other types of radio communication systems. Radio communication systems differ from wired communication systems in that communication in a radio communication system is conducted over a radio frequency (RF) communication channel. More specifically, in a radio communication system, information is modulated into a form suitable for RF communication using a modulation scheme. Such modulation schemes include, for example, amplitude modulation, frequency modulation, and other modulation schemes. The RF communication channel conveys the modulated information from a transmitter to a receiver. The RF communication channel may be established, for example, by an air interface in a cellular telephone system or by a wireless link in a WLAN or WPAN.
To permit different stations or terminals to communicate within the communication system, the communication resources of the communication system are divided into channels. Channels are defined in the communication system, for example, by assigning particular frequencies for use by the communication system. In cellular telephone systems, for example, each base station (BS) defines a number of channels. Channels are assigned to the individual BSs of the cellular telephone system so that transmissions from different BSs do not interfere. As such, if a particular BS is using a first channel to transmit information to a first station and a second BS is using a second channel to transmit 0b46394aab
