| 20090175187 | Method and Arrangement for Triggering Power Headroom Report Transmissions in a Telecommunications System - The present invention relates to a method and arrangement for triggering transmission of a power headroom report to be used by a base station for estimating UE transmit power also for transmissions for which a power headroom report is not included. The user equipment, UE, is to this end configured with a set of triggering conditions for power head room report transmission. | 07-09-2009 |

| 20100202306 | Including in the Uplink Grant an Indication of Specific Amount of CQI to be Reported - The present invention relates to a method, user equipment and a base station adapted to handle channel state feedback reports in a more flexible way. More specifically, a channel state feedback procedure is provided which utilizes the resources available for transmission of channel state feedback more efficiently. This is achieved by including uplink grant availability into the channel state feedback reporting triggers used for determining when and how to send channel state feedback from a UE, i.e. a channel state feedback reporting request may be sent by a base station in an uplink grant to a UE comprising an indication of an expected amount of information to be returned. | 08-12-2010 |
| 20100202420 | Methods and Systems for Scheduling Resources in a Telecommunication System - Aspects of the present invention relate to the scheduling of resources in a telecommunication system that includes a mobile terminal and base station. In one embodiment, the mobile terminal sends an initial scheduling request to a base station. Subsequently, the mobile terminal does not transmit a scheduling request to the base station unless and until a scheduling request triggering event is detected. | 08-12-2010 |

| 20110021230 | Method of Transmitting CQI Reports - In a cellular radio system a UE transmits CQI reports on a periodic basis and also transmits CQI reports upon a request from the radio base station. The UE is further adapted to cancel transmission of a periodic CQI report upon reception of a request for a requested CQI report. | 01-27-2011 |

| 20110128930 | Method for Link Adaptation with a Signal Quality Margin on the Bandwidth - Method and arrangement in a base station for selecting a transmission parameter. The selected transmission parameter is used when sending a signal over a radio channel to a user equipment in a wireless communication network. The radio channel is allocated bandwidth for signalling. The method comprises the step of obtaining an estimation of the signal quality of the radio channel. Also, the allocation to the radio channel. Further yet, the method may comprise the step of calculating a signal quality margin, which signal quality margin is based on the bandwidth size. Still further, the method comprises the step of selecting the transmission parameter based on the estimated signal quality of the radio channel and the calculated signal quality margin. | 06-02-2011 |
| 20110134780 | Method of Requesting CQI Reports - In a method and a device for requesting Channel Quality Indication (CQI) reports from a mobile station of a cellular radio system, the CQI reports are requested in response to a measured Block Error Rate (BLER) of transmissions from the mobile station. In accordance with one embodiment of the present invention a CQI report is requested if the BLER of the mobile station is above a predetermined threshold value C. The threshold value C can be set to a value related to the BLER target. In particular the value C can be set to the same value or as a value close the BLER that is targeted to try to adapt the CQI report request to how well the base station knows the channel. It can also be set higher or lower to also consider how much CQ1 reporting the base station estimates can be afforded when it comes to uplink resources and uplink grant signaling in the downlink. | 06-09-2011 |
