20120202513 | Method and Arrangement in a Wireless Communication System - Method and arrangement in base station for allocating control elements in a message comprising a predetermined number of control elements, to user equipments to be scheduled. Each user equipment is associated with a priority value, is adapted to communicate with the base station over a radio link and requires a certain number of control elements, depending on the link quality of the radio link. The method comprising sorting user equipments in a scheduling priority list and associating control elements with user equipments by selecting user equipments from the scheduling priority list and summing up the total amount of required control elements by adding the required number of control elements of each user equipment respectively, until the predetermined number of control elements in the message is reached, if two or more user equipments have been associated with the same control elements, the control elements are re-associated between the user equipments. | 08-09-2012 |
20120300739 | Selection of Transport Format in Wireless Communication Systems - Disclosed herein is a first network node and a method in a first network node for selecting a transport format among a plurality of available transport formats for communicating information with a second network node via a wireless link, which transport formats are such that a first transport format has a first maximum capacity and all the other transport formats have a higher maximum capacity in an increasing order. The method comprises the steps of: obtaining a quality indicator, which quality indicator indicates the current channel quality of the wireless link; determining a throughput indicator, which throughput indicator indicates the throughput format being available at the obtained quality indicator; calculating a switching value based on the quality indicator and the throughput indicator; switching to the second transport format when the quality indicator indicates that the switching value is reached or exceeded with respect to the second transport format; sending a notification to the second node, which notification indicates the switch to the second transport format. | 11-29-2012 |
20130005382 | METHOD AND APPARATUS FOR CONTROLLING CHANNEL QUALITY REPORTING MODES USED BY WIRELESS COMMUNICATION NETWORK USERS - According to this disclosure, a base station or other controlling node within a wireless communication network determines which channel state information reporting mode should be used by individual users among a plurality of active users being supported by the network. In particular, the determination is made as to whether or not an individual user should use frequency-selective reporting and, if so, whether the user should report a frequency-selective channel quality indicator or a frequency-selective precoder matrix indicator. | 01-03-2013 |
