Abstract: A wireless communication system includes a pager or similar device that communicates to a home terminal. The home terminal confirms the identity of the pager and attaches a certificate to the message for ongoing transmission. Where the recipient is also a pager, an associated home terminal verifies the transmission and forwards it in a trusted manner without the certificate to the recipient.

Abstract: A method and system for communicating header compression layer control messages. Header compression control messages are generated by a header compression layer (302) and are sent through at least one link layer data packet by a link transport communications protocol layer (304) to a remote receiver (104). The link transport communications protocol layer (304) monitors receipt of link layer data packet acknowledgements that are received from the link transport communications protocol layer (304) of the remote receiver (104) for the at least one link layer data packet. The link transport communications protocol layer (304) determines successful transmission of the header compression control message and provides, to the header compression layer (302), an indication of successful header compression control message transmission.

Abstract: A receiver with DFT based channel estimation having good noise suppression for both high and low signal-to-noise ratios providing advantages over conventional DFT estimators and Minimum-Mean-Square-Error (MMSE) estimators. The use of MMSE may be incorporated for estimation at the band edges providing further improvements. The received signal in the time domain, is transformed to the frequency-domain received signal via an N-point FFT (501). The frequency-domain received signal at the pilot locations is then used to obtain a “noisy” channel estimates at the pilot subcarriers by dividing the known pilot symbols in (503). Uniformly spaced pilots are assumed over a window of usable subcarriers. Padding is applied to the initial channel estimates at both sides of the band to account for unused subcarriers such as guard spacing. Weighting factors during power estimation may take into account various noise characteristics such as combinations of known and time-limited noise power characteristics.

Moreover, in response to the request, the controller assigns a traffic channel. The keying material enables the unique first symmetric key to be securely established between the source and destination endpoints.

Abstract: Communication devices and methods for transmitting and receiving a wideband signal using aggregated discontiguous narrowband channels in a band are presented. During transmission, a fold point is determined in which symmetric free channels are sufficient to transmit the signal. The signal is then synthesized by aggregating the data in the channels and transmitted using the fold point as the up-conversion modulation frequency. During reception, information regarding which channels are being used to provide data signals and which channels are occupied by interferers is received. This information is used to determine one or more fold points as the down-conversion modulation frequencies. The fold points are selected such that an image of each interferer falls on an unoccupied channel or a narrowband channel occupied by another interferer.
