A method and apparatus for admission control in a communication system. An Access Network (AN) element determines available resources. When available resources are sufficient to support the requirements of a requested application flow, the AN admits the application flow. The AN periodically, and on trigger events, updates a measure of available resources. The admission control may operate in coord...

Methods and apparatus to decode encoded data. One method starts and stops turbo decoding depending on channel conditions of a received pilot signal. One method may be used with Hybrid Automatic Repeat Request (H-ARQ).

Techniques are described that allow operation according to two or more different communication modes in a single modulation path of a variable radio frequency (RF) modulator within a multi-mode wireless communication device (WCD). The multi-mode WCD may detect a service signal from a base station within a wireless communication system and select a communication mode in which to operate based on th...

A signaling channel that punctures traffic channels is used to send signaling, e.g., acknowledgments (ACKs). To send signaling, resources for the signaling channel are determined, e.g., based on a frequency hopping pattern. Signaling is spread with a spreading code (e.g., a Walsh code) to generate spread signaling, which is mapped to the resources for the signaling channel. Each resource may be pa...

Techniques are described for sampling rate conversion in the digital domain by up-sampling and down-sampling a digital signal according to a selected intermediate sampling frequency. A prototype anti-aliasing filter that has a bandwidth with multiple factors is stored in memory. The techniques include selecting an intermediate sampling frequency to be an integer multiple of a desired output sampli...

When all of the fingers of a wireless rake receiver are "out-of-lock," the transmit power is initially maintained at a constant level. When the "out-of-lock" condition persists for an extended period of time, transmit power is increased in an effort to reacquire a lock with a subscriber unit or base station, as the case may be. An increase in transmit power may be effective in reacquiring lock whe...

In activated carbon obtained by subjecting a carbonaceous material to an activation treatment, the overall content of alkali metals is set at 100 ppm or less, or the overall content of heavy metals is set at 20 ppm or less and the overall content of alkali metals is set at 200 ppm or less. In cases where such activated carbon is used as a raw material in electronic devices, the formation of dendri...

A cylinder block contains a cylinder liner having an outer circumferential surface on which a film is formed. The film functions to form gaps between the cylinder block and the cylinder liner. Alternatively, the film functions to reduce adhesion of the cylinder liner to the cylinder block. The cylinder liner suppresses excessive decreases in the temperature of a cylinder.
