Patent number: 11245509Abstract: A communication apparatus has a receiver and a transmitter. The receiver, in operation receives a control signal including a Modulation and Coding Scheme (MCS) Index, a channel quality indicator (CQI) trigger and information indicating uplink resource blocks. The transmitter in operation, determines whether to multiplex an aperiodic CQI report with data in an uplink signal based on the MCS Index, the channel quality indicator trigger, the information indicating uplink resource blocks, and a threshold number of resource blocks, and transmits the uplink signal.Type: GrantFiled: January 9, 2020Date of Patent: February 8, 2022Assignee: Godo Kaisha IP Bridge 1Inventors: Alexander Golitschek Edler von Elbwart, Christian Wengerter, Joachim Löhr

Patent number: 11240870Abstract: The disclosure 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: GrantFiled: October 2, 2019Date of Patent: February 1, 2022Assignee: Apple Inc.Inventors: Martin Feuersaenger, Christian Wengerter, Joachim Loehr, Alexander Golitschek Edler von Elbwart

Publication number: 20210195621Abstract: The invention relates to a control channel signal for use in a mobile communication system providing at least two different scheduling modes. Further the invention relates to a scheduling unit for generating the control channel signal and a base station comprising the scheduling unit. The invention also relates to the operation of a mobile station and a base station for implementing a scheduling mode using the control channel signal. In order to facilitate the use of different scheduling schemes for user data transmission while avoiding an additional flag for indicating the scheduling mode in the control signaling, the invention proposes the use of code points in existing control channel signal fields. Further, the invention proposes a specific scheduling mode for use in combination with the proposed control channel signal. According to this scheduling mode control channel information is only provided for retransmissions, while initial transmissions are decoded using blind detection.Type: ApplicationFiled: February 17, 2021Publication date: June 24, 2021Inventor: Christian Wengerter

Patent number: 11012219Abstract: The present invention relates to providing control information within a search space for blind decoding in a multi-carrier communication system. In particular, the control information is carried within a sub-frame of the communication system, the sub-frame including a plurality of control channel elements. The control channel elements may be aggregated into candidates for blind decoding. The number of control channel elements in a candidate is called aggregation level. In accordance with the present invention, the candidates of lower aggregation levels are localized, meaning that the control channel elements of one candidate are located adjacently to each other in the frequency domain. Some candidates of the higher aggregation level(s) are distributed in the frequency.Type: GrantFiled: May 20, 2020Date of Patent: May 18, 2021Assignee: Sun Patent TrustInventors: Alexander Golitschek Edler von Elbwart, Sujuan Feng, Christian Wengerter, Hidetoshi Suzuki

Publication number: 20210127371Abstract: The invention relates to a new structure of a control channel region within a sub-frame of a 3GPP-based based communication system using OFDM in the downlink. This new structure of a control channel region is inter alia particularly suitable for conveying physical downlink control channel information from a donor eNodeB to a relay node. The control channel region is divided in CCEs that have equal size irrespective of the presence of further cell-specific and/or UE-specific reference signals within the control channel region. This is achieved by dividing the control channel region in plural sub-CCEs that are combined to CCEs all having equal size (in terms of resource elements that can be used for the signaling of control information). The control channel region is divided in the frequency domain and/or time domain in a FDM respectively TDM fashion in order to obtain the sub-CCEs.Type: ApplicationFiled: January 5, 2021Publication date: April 29, 2021Inventors: Sujuan Feng, Alexander Golitschek Edler Von Elbwart, Christian Wengerter

Publication number: 20200359340Abstract: 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: July 24, 2020Publication date: November 12, 2020Inventors: Martin Feuersaenger, Joachim Loehr, Christian Wengerter
