Publication number: 20240129863Abstract: Methods inform an eNodeB on the transmit power status of a user equipment in a mobile communication system using component carrier (CC) aggregation. Also described is an implementation of these methods by hardware and 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 the 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: December 18, 2023Publication date: April 18, 2024Inventors: Martin Feuersaenger, Joachim Loehr, Christian Wengerter

Patent number: 11943752Abstract: Provided is a radio communication base station device which can prevent lowering of use efficiency of a channel communication resource for performing a frequency diversity transmission when simultaneously performing a frequency scheduling transmission and the frequency diversity transmission in a multicarrier communication. In the device, a modulation unit (12) executes a modulation process on Dch data after encoded so as to generate a Dch data symbol. A modulation unit (22) executes a modulation process on the encoded Lch data so as to generate an Lch data symbol. An allocation unit (103) allocates the Dch data symbol and the Lch data symbol to respective subcarriers constituting an OFDM symbol and outputs them to a multiplexing unit (104). Here, when a plurality of Dch are used for a Dch data symbol of one mobile station, the allocation unit (103) uses Dch of continuous channel numbers.Type: GrantFiled: August 2, 2022Date of Patent: March 26, 2024Assignee: Panasonic Holdings CorporationInventors: Akihiko Nishio, Christian Wengerter, Hidetoshi Suzuki, Masaru Fukuoka

Patent number: 11937331Abstract: 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: January 4, 2022Date of Patent: March 19, 2024Assignee: Apple Inc.Inventors: Martin Feuersaenger, Christian Wengerter, Joachim Loehr, Alexander Golitschek Edler von Elbwart

Patent number: 11924835Abstract: 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: GrantFiled: January 3, 2023Date of Patent: March 5, 2024Assignee: Panasonic Intellectual Property Corporation of AmericaInventor: Christian Wengerter

Patent number: 11901929Abstract: Provided is a wireless communication apparatus wherein channel estimation accuracy is improved while keeping the position of each bit in a frame, even when a modulation system having a large modulation multiple value is used for a data symbol. In the wireless communication apparatus, an encoding section encodes and outputs transmitting data to a bit converting section, and the bit converting section converts at least one bit of a plurality of bits constituting a data symbol to be used for channel estimation, among the encoded bit strings, into ‘1’ or ‘0’ and outputs it to a modulating section. The modulating section modulates the bit string inputted from the bit converting section by using a single modulation mapper and a plurality of data symbols are generated.Type: GrantFiled: September 6, 2022Date of Patent: February 13, 2024Assignee: Panasonic Holdings CorporationInventors: Kenichi Miyoshi, Hidetoshi Suzuki, Katsuhiko Hiramatsu, Christian Wengerter, Alexander Golitschek Edler Von Elbwart

Patent number: 11611956Abstract: 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: GrantFiled: January 5, 2021Date of Patent: March 21, 2023Assignee: SUN PATENT TRUSTInventors: Sujuan Feng, Alexander Golitschek Edler Von Elbwart, Christian Wengerter
