摘要： Techniques for efficient signaling to and from a plurality of mobile stations are disclosed. In one embodiment, a subset of mobile stations may be allocated a portion of the shared resource with one or more individual access grants, another subset may be allocated a portion of the shared resource with a single common grant, and yet another subset may be allowed to use a portion of the shared resource without any grant. In another embodiment, an acknowledge and continue command is used to extend all or a subset of the previous grants without the need for additional requests and grants, and their associated overhead. In one embodiment, a traffic to pilot ratio (T/P) is used to allocate a portion of the shared resource, allowing a mobile station flexibility in selecting its transmission format based on T/P.

摘要： A current driver circuit, for driving a light source, that provides high accuracy and reduced power consumption is disclosed. The driver includes a digital to analog converter configured to receive a digital value representing a light intensity and convert the digital value to an analog current signal. A current minor is configured to receive the analog current signal and create a current minor output which is larger than the analog current signal based on a ratio of the current mirror. This results in a modified analog current signal. A light source receives the modified analog current signal, and responsive thereto generate a light signal such that the light signal has an intensity controlled by the digital value. One or more amplifiers are also part of the current driver and configured to increase response time and accuracy.

摘要： A method, apparatus and computer program product are provided for triggering a measurement report from a mobile terminal, such as a mobile terminal is in the CELL_FACH state, to a network entity in an instance in which the mobile terminal may be creating neighbor cell interference. Based upon the measurement report, the serving cell may modify the operation of the mobile terminal in order to reduce the potential for neighbor cell interference. In this regard, a method is provided that includes determining two or more parameters indicative of neighbor cell interference. In instance in which the parameters satisfy respective thresholds, the method also causes a measurement report including an indication of at least one of the parameters to be provided to a network element.

摘要： A method, apparatus, computer readable medium is provided to perform resource coordination among multiple cells to cancel near-far interference for device-to-device transmission, including cross-cell device-to-device transmission. In this context, a dedicated resource exchanging channel can be defined between cellular user equipment and device-to-device user equipment for interference control and resource coordination. A cellular user equipment can forward its uplink resource grant information over the dedicated resource exchanging channel when it determines potential interference. A device-to-device user equipment can monitor the dedicated resource exchanging channel in order to identify one or more resources that can potentially interfere with device-to-device transmission.
