20080225729 | Apparatus, methods and computer program products implementing fast bearer prioritization in a MAC-HS packet scheduler based on required activity detection - Apparatus, methods and computer program products provide fast instantaneous overload control during scheduling operations involving users in a wireless communications network who are candidates to be scheduled in a next transmission time interval. Apparatus detect congestion conditions in a wireless communications network by determining an instantaneous operating region of a scheduler (e.g., a medium access control-high speed scheduler) based on required activity detection and prioritize users in a scheduling candidate set based on the cost of a user. In a variant, this may be implemented by combining part of the required activity detection algorithm with a per-bearer cost function. In one implementation, this will limit the number of users that suffer during momentary congestion in the wireless communications network. | 09-18-2008 |
20080240030 | TRANSMISSION ADAPTATION IN A WIRELESS NETWORK - Various example embodiments are disclosed relating to transmission adaptation in a wireless network. According to another example embodiment, an apparatus may include a processor. The processor may be configured to measure a channel quality for a plurality of wireless resources (e.g., physical resource blocks), determine one or more proposed resources based on the measured channel quality for the wireless resources, determine at least one proposed transmission parameter based on a number of the proposed wireless resources and the channel quality of the proposed wireless resources, and send a report to an infrastructure node, the report including the at least one proposed transmission parameter and identifying the proposed wireless resources. | 10-02-2008 |
20080240216 | Link adaptation method - A method, where data is transmitted from a network node to user equipment in a succession of communication frames. An estimate indicative of the quality of the user equipment transmission channel in a reference communication frame is ascertained, and modified by an amount that varies in dependence on a configuration of the resources allocated to the user equipment in the reference communication frame. The modified estimate is used in selecting one or more connection parameters for a data transmission in a target communication frame. This improves the adaptation of the transmission parameters to the existing channel conditions | 10-02-2008 |
20080268863 | Method and Apparatus for Reporting Channel Quality - An approach is provided for efficient signaling for reporting of channel quality information. A parameter is set for a silent period associated with reporting of channel quality information. The channel quality information is transmitted by the terminal only during a time instant outside of the silent period. The silent period is a time interval before transmission of the quality information by the terminal to an inactive state from an active state. | 10-30-2008 |
20090080342 | Determining load measure for network element - The specification and drawings present a new method, system, apparatus and software product for determining (e.g., calculating) a load measure by a network element (e.g., Node B or any other network element) for optimizing information traffic in communication networks (e.g., wireless communication systems). This load measure may represent the amount of available/excess traffic that a given network element may carry and is a relative measure, which would take into account the total amount of resources available in the system and the amount of resources that are free for carrying only “important” or “essential” traffic, using a weighed method described herein. | 03-26-2009 |
20090323617 | METHOD AND APPARATUS FOR PROVIDING ACKNOWLEDGMENT BUNDLING - An approach is provided for acknowledgement bundling. Dynamically scheduling of one or more of subframes per bundling window is performed by reusing an assignment index field (e.g., downlink assignment index (DAI) field). The assignment index field has a value greater than or equal to number of previously assigned subframes within the bundling window. The bundling window defines a group of subframes for common acknowledgement. | 12-31-2009 |
20100110878 | METHOD AND APPARATUS FOR PROVIDING CONTROL SIGNALING - An approach is provided for an efficient control signaling associated with an error control scheme. A determination is made whether data has been properly received according to an error control scheme. A first pilot sequence representing an acknowledgement is generated if the data is properly received. A second pilot sequence representing a negative acknowledgement is generated if the data is not properly received. A frame including either the first pilot sequence or the second pilot sequence is output. | 05-06-2010 |
20100260115 | METHOD AND APPARATUS FOR PROVIDING AUTOMATIC CONTROL CHANNEL MAPPING - An approach is provided for control signaling. A sub-set of channel parameters is received. Control channels are automatically mapped to physical resources of a communication network according to the received channel parameters. | 10-14-2010 |
20100284348 | METHOD AND APPARATUS FOR ALLOCATING RESOURCES USING NESTED BIT MAPPING - An approach is provided for generating a control signal for allocating one or more physical resource blocks to a terminal for communicating over a network. The control signal is separately coded and utilizes a nested bit mapping scheme to specify the allocation. | 11-11-2010 |
20110268053 | PHYSICAL UPLINK CONTROL CHANNEL ACK/NACK INDEXING - A method for controlling channel signaling between a UE and a wireless network access node is described. The method includes determining whether an examined sub-frame of a plurality of sub-frames in a first resource region is unused. The index of the examined sub-frame is a last index of the plurality of sub-frames allocated for use in a first channel. The plurality of sub-frames is organized in a reverse indexing manner such that a last indexed sub-frame is adjacent to a second resource region. The second resource region is allocated to a second channel. In response to determining that the w examined sub-frame is unused, the examined sub-frame is re-allocated for temporary use in the second channel. The method also includes providing an indication of the allocation. Apparatus and computer readable media are also described. | 11-03-2011 |
20120213175 | ADAPTIVE SCHEME FOR LOWERING UPLINK CONTROL OVERHEAD - The present invention is related to methods, apparatuses, systems and computer software for determining an amount of physical resources for downlink transmission, and allocating uplink physical resources for transmission of data-non-associated control signaling based at least on the amount of physical resources for downlink transmission. The amount of physical resources for downlink transmission comprises an amount of downlink control signaling. The present invention further relates to a framework for mapping the dedicated uplink control channels directly to single physical resource blocks. The framework is able to efficiently shift physical resources to and from the uplink control channel for ACK/NACK reports, in a data-non-associated control signaling scheme and on a per subframe basis. The present invention is also concerned with scheduler, for example an eNodeB scheduler, which uses its scheduling history and knowledge of user equipment capabilities to increase utilization of uplink resources. | 08-23-2012 |
