The invention relates to methods for improving a scheduling request transmission between a UE and a base station. The transmission of the scheduling request is postponed, by implementing a threshold that the data in the transmission buffer has to reach, before a transmission of the scheduling request is triggered. In one variant, the data in the transmission buffer needs to reach a specific amount, to trigger a scheduling request. The invention refers to further improvements: the PDDCH monitoring time window is delayed after sending a scheduling request; the dedicated scheduling request resources of the PUCCH are prioritized differently such that low-priority scheduling requests are transmitted less often.

Threshold-based and power-efficient scheduling request procedure

The invention relates to methods for avoiding in-device coexistence (IDC) interference in a mobile terminal in a mobile communication system, apparatus for performing these methods, and computer readable media instructions to cause the apparatus to perform the methods. In order to avoid IDC interference, an IDC interference indication is reported for at least one of a first cell and a second cell on which an interference condition is detected. In response, an activation/deactivation pattern is received for at least one of the first and second cells for which the interference condition is detected. The activation/deactivation pattern indicates an off-duration and an offset specifying a time-period during which communication via the at least one of the first and second cells is to be deactivated. According to the activation/deactivation pattern, first and second subframes are determined, at which the communication via the at least one of the first and second cells is to be deactivated and re-activated, respectively.

Maximization of scheduling opportunities in in-device coexistence interference scenarios

The present invention relates to performing radio resource management tasks in a communication system including at least a base station and a terminal. In order to avoid inconsistencies in executing the radio resource management tasks for the dual-priority devices, which may run a delay-tolerant and a normal application at the same time, when the device priority changes, the change is indicated to the base station either from the terminal or from the core network. The device priority may be indicated as an overall priority per device or as a priority per bearer configured for the device.

Radio resource management for dual priority access

The invention relates methods for maximum output level reporting by a mobile terminal in a mobile communication system. The invention is also providing apparatus for performing these methods, and computer readable media the instructions of which cause the apparatus to perform the methods described herein. In order to allow for maximum output level reporting, a power management related power backoff value is first calculated for one radio technology by referring to a reception quality level set for communication via the other radio technology; thereafter a lower and upper bounds of a maximum output power level is calculated, then the maximum output power level (P) for communication is set within the determined lower and upper bounds and finally the set maximum output power level is reported to a base station wherein the lower bound (P) may be calculated using MPR=0 dB, A-MPR=0 dB, and optionally &#x394;T=0 dB.
