20090268696 | Method And Arrangement In A Mobile Telecommunication Network - The present invention is based on the idea to allocate HS-DSCH power at TTI based on the HS-SCCH allocation of TTI and an estimation of the HS-SCCH allocation of TTI+1. The estimation of the HS-SCCH allocation of TTI+1 is based on estimation of which users that will be scheduled at the time denoted TTI+1. i.e., the users that have a high probability to be selected for transmission by the scheduler at the time denoted TTI+1 are determined. That is performed by calculating for each user the probability that the user will be selected for transmission by the scheduler The users that have a high probability to be scheduled at the time TTI+1 are included in a candidate set according to the | 10-29-2009 |
20100234058 | Channel Quality Prediction in HSDPA Systems - A method and arrangement in a radio communication network for predicting channel quality on a downlink channel. A radio base station (RBS) transmits data on the downlink channel to one or more user equipments (UEs), each of which transmits a channel quality indicator to the RBS on an uplink channel. The RBS derives a needed downlink transmission power from the received channel quality indicator, and predicts a channel quality for a next downlink transmission based on the received channel quality indicator and the derived downlink transmission power. | 09-16-2010 |
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 |

20140307643 | Wireless Device and Method for Selecting Uplink Transmission Parameters - The present invention relates to a method for selecting a set of uplink transmission parameters. The method is performed in a wireless device of a radio communications system. The method comprises obtaining information mapping resources of a physical downlink control channel region to at least two sets of uplink transmission parameters. The method also comprises receiving a downlink control message on a resource of the physical downlink control channel region, and selecting a set among the at least two sets of uplink transmission parameters. The selection of set is based on the resource of the physical downlink control channel region on which the downlink control message is received, and on the obtained information mapping resources of the physical downlink control channel region to the at least two sets of uplink transmission parameters. | 10-16-2014 |
