摘要： A narrowband communication system (100) includes a base station (102) and a plurality of subscriber units (104). The base station assigns one or more wideband channels to be measured to each subscriber unit (606). The subscriber units tune to their assigned wideband channels and perform narrowband measurements, then report the results to the base station (612). The base station then analyzes the measurement results (614) and selects available wideband channels to be divided into narrowband channels for use by the narrowband system.

摘要： A wireless communication network is provided in which a plurality of radio devices achieve frequency diversity. By utilizing cognitive capability within the radio devices to iteratively select frequency sets, a lowest cardinality frequency set is generated and used to communicate amongst the plurality of radio devices. Each radio device can have different hardware, as the iterative selection of frequency set can take into account the different hardware capabilities of the radio devices.

摘要： A combination of subscriber clustering and link interleaving provides a cognitive radio system (CR) 100 with opportunities to sense an incumbent system's spectrum on secondary basis. The CR system (100) uses clustering to identify out-of-band channels. The CR system (100) uses link interleaving during a second mode of operation to sense and detect any incumbent (120) on in-band channels. A list of out-band channels are sensed by clusters (0, 1, 2, 3) sequentially to generate a ranked list of potential channels for future use by the CR system. These out-of-band channels can be used opportunistically in case of in-band incumbent detection.

摘要： Efficient frequency spectrum sharing between at least one incumbent communication system(s) (102, 152) and at least one cognitive radio (CR) system (105) is provided. The incumbent system's system parameters and CR system's operational requirements are copied to a mirrored database (106B). The mirrored database (106B) is controlled by a either a central authority (108) or a database manager having delegated authority (508). The mirrored database (106B) is accessed by the CR system (105). The mirrored database (106B) can be modified and updated by the central authority (108) or delegated database manager (508) to correct for interference detected in the incumbent system caused (152) by the cognitive radio system (105). The cognitive radio system (105) utilizes the updated mirrored database (106B) to avoid interfering with the incumbent system (102, 152) to determine CR system operating parameters thus enhancing the ability to share spectrum.

摘要： A remote station (202) communicates with a base station (204) over a secondary radio channel (206). During communication, the remote station determines channel conditions of the secondary radio channel. Based on the channel conditions, the remote station selects one or more sensing methods to be performed on the secondary radio channel. The result of performing the sensing method is used to determining whether an incumbent signal is present on the secondary radio channel.
