| 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 |
| 20080259802 | Frequency domain packet scheduling under fractional load - Methods, apparatus and computer program products implement frequency domain packet scheduling in a fractional load situation by detecting a fractional load situation in a wireless communications network; receiving information indicative of signal conditions in a cell; using the information indicative of signal conditions in the cell to determine physical resource blocks in use in a nearby cell; determining how many physical resource blocks are need to perform packet transmission operations in dependence on packet traffic in the cell; selecting particular physical resource blocks to be used to perform initial packet transmission operations in the cell downlink so as to avoid those physical resource blocks in use in the nearby cell; and when selecting physical resource blocks to perform future packet transmission operations in the cell downlink, favoring those physical resource blocks used to perform initial packet transmission operations. | 10-23-2008 |
| 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 |
| 20090275323 | Initial eNode-B configuration over-the-air - A method, apparatus, system, and computer program embodied on a computer readable medium is provided to define new messages to be transmitted over a broadcast channel to better support uncoordinated base station deployment in a local area environment. In this context, uncoordinated local base station deployment refers to cases where new base stations are placed, and activated, without any detailed a priori network planning and considerations for placement of already active base stations in the area. | 11-05-2009 |
| 20110086657 | CELL SEARCH FOR FLEXIBLE SPECTRUM USE - Structure of a multi-carrier flexible spectrum wireless cell is determined from received synchronization or broadcast channels of detected individual carriers. The determined structure is used to select an intended carrier for initial access or cell reselection to the flexible spectrum wireless cell. The structure may have carriers compatible with an earlier version (LTE/Release | 04-14-2011 |
