An apparatus, system and method are provided for transmitting data from logical channel queues over a telecommunications link, each of the logical channel queues capable of being associated with quality of service attributes, the method including determining available resources for transmission over the telecommunications link in a frame; selecting one of the logical channel queues based on a first one of the quality of service attributes; packaging data from the selected one of the logical channel queues until one of: a second one of the quality of service attributes for the selected one of the logical channel queues is satisfied, the available resources are used, or the selected one of the logical channel queues is empty; and repeating the selecting step and the packaging step for remaining ones of the logical channel queues.

Apparatus, system and method for the transmission of data with different QoS attributes

Apparatus, system and method for the transmission of data with different QOS attributes

A novel apparatus, system and method for transmitting data flows having different quality of service (QoS) attributes over a network link structured in two or more channels is provided. The method classifies arriving packets to determine their required/assigned QoS attributes and places the classified packets into one of several logical channel queues, the selected logical channel queue having an appropriate corresponding set of QoS attributes defined. A radio link controller examines the available channels and, for each channel, selects a logical channel queue whose contents will be transmitted thereon. The radio link controller determines the data transmission capacity for each channel and segments the contents of the selected logical channel to fit within the determined capacity. The selection of the logical channel queue is performed in accordance with the set of QoS attributes and thus each flow can have different QoS characteristics including priorities, reliabilities (ARQ, no ARQ, etc.).

A system and method of determining the maximum uplink transmit power of a subscriber station from a remote base station where the subscriber station reports incidents of foldback in its radio to the base station. When the base station receives the report, it reduces the maximum uplink transmit power of the subscriber station. After a period of time lapses without any reports of foldback occurring, the base station increases the maximum uplink transmit power of the subscriber station.
