20090196237 | TRANSMISSION-COMPENSATED RADIO CHANNEL QUALITY - A channel quality of a radio channel between a transmitter and a receiver is detected by the receiver. The channel quality is compensated for an affect of a transmission on the radio channel when the receiver detected the channel quality or an affect of a future transmission on the radio channel. In a preferred example embodiment, the channel quality is compensated for both affects if present. The compensated channel quality is then used to determine one or more parameters for transmission from the transmitter to the receiver over the radio channel, e.g., an amount of data to be transmitted, a transmission power, and/or a transmission time period. | 08-06-2009 |

20110026408 | ERROR RATE MANAGEMENT - The invention deals with the adjustment of the nominal target error rate for transmission of data from a priority queue to a new predetermined target error rate depending on the state of the priority queue. Usually, the adjustment to the new predetermined target error rate will be to a predefined lower target error rate based on states of the priority queue, such as amount of data in the priority queue, time passed since the latest transmission of data from the priority queue, whether the amount of data in the priority queue will fit into one transport block, whether the data unit to be transmitted for the priority queue is the first or last data unit in the priority queue and may also be based on the type of data stored in the priority queue. There may be more than one such priority queue. | 02-03-2011 |

20110249563 | Dynamic Adaptation of Downlink RLC PDU Size - Embodiments herein dynamically adapt the size of downlink Radio Link Control (RLC) protocol data units (PDUs) sent by a radio network controller (RNC) to a user equipment (UE) via a base station. Notably, the RNC effectively matches downlink RLC PDU size to the radio conditions at the UE using one or more indirect indicators of those radio conditions. Example indirect indicators include active set size, common pilot channel power, and the number of positive RLC PDU acknowledgments received, to name a few. The embodiments therefore prove particularly advantageous to wireless communication systems based on existing standards that already provide the RNC with such indirect indicators, since no new or additional control signaling need be introduced. Method embodiments herein thus include determining one or more indirect indicators of radio conditions at the UE, and dynamically adapting the size of downlink RLC PDUs in dependence on those one or more indirect indicators. | 10-13-2011 |

20130034014 | RLC STATUS REPORTING FOR EIGHT-CARRIER HSDPA - Techniques for signaling radio link control (RLC) status reports to a wireless network, such as a network supporting multi-carrier High-Speed Downlink Packet Access (HSDPA). An example method performed in a mobile terminal comprises calculating a throughput estimate data transmissions to the mobile terminal, determining a rate at which to send radio link control status reports, based on the throughput estimate, and sending radio link control status reports to the wireless network node at the determined rate. In some embodiments, the mobile terminal determines the rate at which to send radio link control status reports by comparing the throughput estimate to a threshold value and selecting the rate based on the comparison. The threshold value may be received from the wireless network node prior to the comparison. | 02-07-2013 |
