Publication number: 20240163044Abstract: A communication apparatus includes a receiver and a transmitter. The receiver, in operation, receives from a neighboring cell a reference signal mapped to at least one first resource element. No signal is received from a serving cell on the at least one first resource element. The transmitter, in operation, transmits to a base station measurement information obtained based on the reference signal.Type: ApplicationFiled: January 19, 2024Publication date: May 16, 2024Inventors: Hui TONG, Ming XU, Masayuki HOSHINO, Daichi IMAMURA

Patent number: 11963141Abstract: Method of scrambling signals, transmission point device, and user equipment using the method are provided. The method includes: sending an ID table to a user equipment through higher layer signaling, the ID table being a subset of the whole ID space and containing available IDs for the user equipment; notifying the user equipment an ID in the ID table to be used through physical layer signaling or UE specific higher layer signaling; generating a random seed based on the notified ID; initializing a scrambling sequence by the random seed; and scrambling the signals with the initialized scrambling sequence. The method of the disclosure, by combining physical layer signaling and higher layer signaling, may notify the used group ID and the blind detection space to a UE, wherein the blind detection for the UE is enabled and the signaling overhead is reduced.Type: GrantFiled: April 21, 2023Date of Patent: April 16, 2024Assignee: SUN PATENT TRUSTInventors: Zhi Zhang, Ming Xu, Masayuki Hoshino, Daichi Imamura, Akihiko Nishio

Patent number: 11949626Abstract: The present disclosure provides a terminal device that allows constraints on user allocation to be prevented and spread codes to be allocated in a scheduler when non-adaptive HARQ is employed using a PHICH. A codeword generator generates code words by encoding data, a layer mapping unit places each CW in one or a plurality of layers, a DMRS generator generates a reference signal for each layer in which a CW is placed by using any resource among a plurality of resources defined by a mutually orthogonal plurality of OCCs, and an ACK/NACK demodulator receives a response signal indicating a retransmission request. When a response signal requesting retransmission of only a CW placed in a plurality of layers is received, the DMRS generator uses each resource having the same OCC among the plurality of resources for the reference signals generated in the corresponding layers.Type: GrantFiled: January 3, 2023Date of Patent: April 2, 2024Assignee: Sun Patent TrustInventors: Masayuki Hoshino, Akihiko Nishio, Daichi Imamura

Patent number: 8998352Abstract: A vehicle brake control device includes a master cylinder, a plurality of wheel cylinders, a VDC brake hydraulic pressure unit, a motor controller and an integration controller. When a brake operation is carried out, the integration controller carries out a regenerative brake control which achieves a target deceleration. Additionally, a motor suspension control is carried out which suspends a drive status of the VDC motor when the vehicle velocity is less than a first prescribed value. Furthermore, when the vehicle velocity exceeds a second prescribed value and the brake operation is carried out while the VDC motor is in the suspended status, the value of the target deceleration is set to a lower value than the value of the target deceleration which the driver requests, and a motor reactivation control is carried out which reactivates the VDC motor.Type: GrantFiled: September 30, 2011Date of Patent: April 7, 2015Assignee: Nissan Motor Co., Ltd.Inventor: Masayuki Imamura
