Publication number: 20160021624Abstract: The invention relates to methods for informing an eNodeB on the transmit power status of a user equipment in a mobile communication system using component carrier (CC) aggregation. Furthermore, the invention is also related to the implementation of these methods by hardware and their implementation in software. The invention proposes procedures that allow the eNodeB to recognize the power usage status of a UE in a communication system using carrier aggregation. The UE indicates to the eNodeB, when the UE is close to using its total maximum UE transmit power or when it has exceeded same. This is achieved by the UE including indicator(s) and/or new MAC CEs to one or more protocol data units transmitted on respective component carriers within a single sub-frame that is providing the eNodeB with power status information. The MAC CEs may report a per-UE power headroom. Alternatively, the MAC CEs may report per-CC power headrooms and/or power reductions applied to the respective uplink CCs.Type: ApplicationFiled: September 25, 2015Publication date: January 21, 2016Inventors: Martin Feuersaenger, Joachim Loehr, Christian Wengerter

Publication number: 20150305061Abstract: The invention relates to methods for transmitting a buffer status report (BSR) in a mobile communication system, more particularly to the definition of rules for triggering, generating and transmitting BSRs. The invention also relates to a data transmission method utilizing new rules to decide data of which radio bearers is transmitted within a given transmission time interval. Moreover, the invention relates to scheduling method for radio resources that is taking into account additional scheduling-relevant information from the buffer status reporting and/or data transmission method. To avoid unnecessary grants from the network and to suggest an advanced handling of data transmissions the invention suggests a buffer status reporting and data transmission schemes that take into account the scheduling mode of data of radio bearers pending for transmission to decide whether to report on it in a buffer status report, respectively, whether to multiplex the data to a transport block for transmission.Type: ApplicationFiled: June 9, 2015Publication date: October 22, 2015Inventors: Martin Feuersaenger, Joachim Loehr, Christian Wengerter

Publication number: 20150195795Abstract: 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 (PCMAX) 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 (PCMAX—L) may be calculated using MPR=0 dB, A-MPR=0 dB, and optionally ?Tc=0 dB.Type: ApplicationFiled: August 2, 2013Publication date: July 9, 2015Inventors: Joachim Loehr, Martin Feuersaenger, Prateek Basu-Mallick

Publication number: 20150189675Abstract: The invention relates to methods for adjusting the transmit power utilized by a mobile terminal for uplink transmissions, and to methods for adjusting the transmit power used by a mobile terminal for one or more RACH procedures. The invention is also providing apparatus and system for performing these methods, and computer readable media the instructions of which cause the apparatus and system to perform the methods described herein. In order to allow for adjusting the transmit power of uplink transmissions on uplink component carriers, the invention suggests introducing a power scaling for uplink PRACH transmissions performing RACH procedures on an uplink component carrier.

Publication number: 20150141030Abstract: 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.Type: ApplicationFiled: August 1, 2013Publication date: May 21, 2015Inventors: Prateek Basu-Mallick, Genadi Velev, Takashi Tamura, Joachim Loehr, Martin Feuersaenger

Publication number: 20150117342Abstract: 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.Type: ApplicationFiled: February 6, 2013Publication date: April 30, 2015Inventors: Joachim Loehr, Takahisa Aoyama, Prateek Basu-Mallick, Takashi Tamura, Martin Feuersaenger

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 interference reporting, the mobile terminal detects an interference condition between the communication with the base station via the first resource and a communication with the wireless communication device via the second resource, reports on the interference condition to the base station; receives reconfiguration information indicating a third resource and reconfigures the communication with the base station to the third resource.Type: ApplicationFiled: February 15, 2013Publication date: February 19, 2015Inventors: Martin Feuersaenger, Joachim Loehr, Christian Wengerter, Prateek Basu-Mallick

Publication number: 20150003311Abstract: The invention relates to methods for improving the DRX operation of a UE by introducing an additional DRX wake-up cycle, which runs in parallel to the short and/or long DRX cycle. The DRX wake-up cycle defines time intervals after which the UE starts monitoring the PDCCH for a wake-up duration of time; the UE does not perform any other operation during the wake-up duration apart from monitoring the PDCCH. The time intervals of the wake-up cycle between the wake-up durations are preferably shorter than the one of the DRX long cycle, and may have the same or a shorter length than the ones of the DRX short cycle. The wake-up duration may be as long as the on-duration of the DRX short/long cycle, or may be preferably much shorter, such as only one or a few subframes.Type: ApplicationFiled: November 23, 2012Publication date: January 1, 2015Inventors: Martin Feuersaenger, Christian Wengerter, Joachim Loehr, Alexander Golitschek Edler von Elbwart
