    Abstract: 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 CQI reporting the base station estimates can be afforded when it comes to uplink resources and uplink grant signaling in the downlink.

    Abstract: In a method of improved channel-sounding transmissions between a base station in communication with a user equipment in a telecommunication system, the user equipment receiving (S0) an assigned channel-sounding transmission pattern from the base station, and transmitting (S1) a channel-sounding signal to the base station based on the assigned channel-sounding transmission pattern and on available uplink data at the user equipment.

    Abstract: 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.

    Abstract translation: 本发明涉及一种适于以更灵活的方式处理信道状态反馈报告的方法，用户设备和基站。 更具体地，提供了一种更有效地利用可用于传输信道状态反馈的资源的信道状态反馈过程。 这通过将上行链路许可可用性包括在用于确定何时以及如何从UE发送信道状态反馈的信道状态反馈报告触发中来实现，即，信道状态反馈报告请求可以由基站在上行链路授权中发送到 UE包括要返回的预期信息量的指示。

    Abstract: A user equipment unit (30) and a base station node (28) which is configured for operation with a synchronous HARQ protocol and with capability of sending data on an E-DCH channel either (1) in a nominal mode in single transmission time intervals of a predetermined length, or (2) in an extended mode in a pseudo transmission time interval. The pseudo transmission time interval comprises a first transmission time interval in which the data is transmitted and a second transmission time interval in which the data is re-transmitted. The second transmission time interval is consecutive to the first transmission time interval, and the first transmission time interval and the second transmission time interval are each of the (same) predetermined length.
