The transmitting device constructs a multiple input multiple output (MIMO) precoding matrix considering the FD response of the PAPR reduction precoding and applies the MIMO precoding matrix and the PAPR reduction precoding to an FD signal. A receiving device applies the FD response conjugated to a received FD signal from the transmitting device and processes at least a received reference signal based on the PAPR reduction precoder.Type: GrantFiled: April 12, 2022Date of Patent: May 6, 2025Assignee: QUALCOMM IncorporatedInventors: Noam Zach, Guy Wolf, Gideon Shlomo Kutz

Patent number: 11817983Abstract: The present invention relates to a method and an apparatus for transmitting and receiving a reference signal in a wireless communication system. In the method, in order to dynamically switch an uplink (UL) Demodulation-Reference Signal (DM-RS) according to the communication environment, such as CoMP and MU-MIMO, a parameter set for generation of a reference signal sequence is configured to include a Virtual Cell Identifier (VCID) parameter configured by information of a total of 9 bits and a cyclic shift hopping initial value parameter cinitCSH, which is 9-bit information representing one integer value among 510 integer values. Therefore, it may be possible to achieve dynamic transmission or reception of a reference signal and channel estimation through the dynamic transmission or reception of the reference signal even when the communication environment dynamically changes as in a Cooperative Multiple Point transmission and reception (CoMP) scenario.Type: GrantFiled: July 14, 2022Date of Patent: November 14, 2023Assignee: PANTECH CORPORATIONInventor: Sung Jun Yoon

Patent number: 11777715Abstract: A method for generating a shared secret is disclosed. In an example embodiment, a sequence of data packets is transmitted from a first node to a second node. A packet error bitmap corresponding to packets in the sequence of packets that are received correctly in a first transmission attempt is generated at the second node. Further, the packet error bitmap is transmitted from the second node to the first node. Then, the first node and the second node separately mixes the packets received correctly in the first transmission attempt to generate the shared secret.Type: GrantFiled: May 15, 2020Date of Patent: October 3, 2023Inventor: Amir Keyvan Khandani

Patent number: 11765749Abstract: A selected network element is arranged for distributed transmission resource allocation conflict reduction. The selected network element receives a transmission from one of a first other network element and a second other network element and identifies at least one transmission resource indicated by the received transmission as being reserved by the first other network element and the second other network element. The selected network element stores an indication of each of the at least one identified transmission resource. In response to reading the stored indications, the selected network element selects a different transmission resource that is different from the transmission resource indicated by the stored indications. The selected network element transmits a transmission from the selected network element using the selected different transmission resource.Type: GrantFiled: September 19, 2022Date of Patent: September 19, 2023Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Wonsoo Kim, Il Han Kim, Jianwei Zhou

Patent number: 11757688Abstract: A sequence-based signal processing method and apparatus are provided. A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined. The sequence is a sequence {fn} consisting of 12 elements, fn represents an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition. Then, the 12 elements in the sequence {fn} are respectively mapped to 12 subcarriers, to generate a first signal, and the first signal is sent. By using the determined sequence, when the signal is sent by using the PUCCH, a low correlation between sequences can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and a relatively small cubic metric (CM) value can be maintained. Therefore, a requirement of a communication application environment in which the signal is sent by using the PUCCH is met.Type: GrantFiled: May 2, 2022Date of Patent: September 12, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Bingyu Qu, Hao Sun

Patent number: 11742893Abstract: In embodiments, instead of a uniform (global) hopping pattern that is used equally by all data transmitters and data receivers of a communication system, data transmitters and the data receiver use an individual hopping pattern for the communication. This individual hopping pattern may depend on an operation and is therefore only used by the data transmitter and the data receiver themselves or by a small group of data transmitters and/or data receivers, which may significantly increase the interference immunity.Type: GrantFiled: October 11, 2019Date of Patent: August 29, 2023Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FĂ–RDERUNG DER ANGEWANDTEN FORSCHUNG, E.V.Inventors: Johannes Wechsler, Gerd Kilian, Josef Bernhard, Dominik Soller, Jakob Kneissl, Alexej Jarresch, Raimund Meyer, Frank Obernosterer
