Publication number: 20240171442Abstract: Aspects of the disclosure relate to techniques for peak-to-average power ratio (PAPR) reduction based on a tone reservation (TR) algorithm. For a TR algorithm, a suitable subset of tones from among a full set of tones in a given resource allocation are reserved for use as peak reduction tones (PRT). An apparatus such as a transmission/reception point receives a set of one or more PRT sequences and stores them in memory. The transmission/reception point then determines a set of PRTs based on one or more later-received PRT sequence selection parameters. Other aspects, embodiments, and features are also claimed and described.Type: ApplicationFiled: January 30, 2024Publication date: May 23, 2024Inventors: Hung Dinh Ly, Saeid Sahraei, Gokul Sridharan, Krishna Kiran Mukkavilli

Patent number: 11991643Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.Type: GrantFiled: February 22, 2022Date of Patent: May 21, 2024Assignee: QUALCOMM IncorporatedInventors: Yi Huang, Prashanth Haridas Hande, Jay Kumar Sundararajan, Gokul Sridharan, Wei Yang, Wanshi Chen, Krishna Kiran Mukkavilli, Allen Minh-Triet Tran, Joseph Patrick Burke, Naga Bhushan

Publication number: 20240162951Abstract: A base station performs joint channel estimation for a set of physical uplink shared channels (PUSCHs) with bundled DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUSCHs, each PUSCH of the set of PUSCHs comprising a corresponding DMRS from the base station. The base station transmits, and the UE receives, a sounding reference signal resource indicator for each PUSCH of the set of PUSCHs. The UE transmits the PUSCHs based on a same sounding reference single resource, the SRI for a first PUSCH of the set of PUSCHs indicating the same SRS resource.Type: ApplicationFiled: January 25, 2024Publication date: May 16, 2024Inventors: Hung Dinh LY, Gokul SRIDHARAN, Wei YANG, Krishna Kiran MUKKAVILLI

Patent number: 11968068Abstract: A transmitting device applies a first MCS to a first set of data tones that overlaps with a first set of PRTs within a plurality of tones, the first set of PRTs being associated with a first PAPR reduction signal. The transmitting device applies a second MCS to a second set of data tones that overlaps with a second set of PRTs within the plurality of tones, the second set of PRTs being associated with a second PAPR reduction signal. The transmitting device can transmit a transmission signal comprising the first set of data tones and the second set of data tones, the transmission signal using a waveform based at least in part on the first PAPR reduction signal and the second PAPR reduction signal.Type: GrantFiled: May 26, 2021Date of Patent: April 23, 2024Assignee: QUALCOMM IncorporatedInventors: Peter Gaal, Saeid Sahraei, Krishna Kiran Mukkavilli, June Namgoong, Gokul Sridharan

Publication number: 20240098793Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a collision between an access link communication and a sidelink communication. The UE may resolve the conflict based at least in part on a priority associated with the access link communication and a priority associated with the sidelink communication. Numerous other aspects are provided.Type: ApplicationFiled: December 1, 2023Publication date: March 21, 2024Inventors: Seyedkianoush HOSSEINI, Gokul SRIDHARAN, Wanshi CHEN, Krishna Kiran MUKKAVILLI

Patent number: 11917689Abstract: Aspects of the disclosure relate to random access procedures. In one example, a UE initiates a random access procedure with a base station, and receives a random access response (RAR) message from the base station in response to the initiating of the random access procedure. The UE further determines a redundancy version (RV) pattern comprising a sequence of a plurality of RVs. The UE also transmits an uplink (UL) communication to the base station as part of the random access procedure. The UL communication comprises a plurality of repetitions of a UL message, each repetition being an iteration of the UL message that is configured by applying a respective RV of the plurality of RVs to the UL message based on the sequence. The UE further receives a downlink message from the base station based on the UL message. Other aspects, embodiments, and features are also claimed and described.Type: GrantFiled: July 1, 2021Date of Patent: February 27, 2024Assignee: QUALCOMM IncorporatedInventors: Hung Dinh Ly, Gokul Sridharan, Hwan Joon Kwon, Krishna Kiran Mukkavilli

Patent number: 11916718Abstract: Techniques for peak-to-average power ratio (PAPR) reduction are described. Wireless devices may use one or more PAPR shaping resources, such as expanded bandwidth and/or pulse-shaping filtering, for shaping a signal to reduce PAPR. For example, expanded bandwidth may be utilized for adding a cyclic affix (CA), such as may comprise a cyclic prefix (CP), cyclic suffix (CS), etc., and combinations thereof, to a frequency domain data signal to provide a CP augmented frequency domain data signal used to generate a reduced PAPR time domain data signal. Additionally or alternatively, pulse-shaping filtering may be applied to a frequency domain signal to provide a pulse-shaped frequency domain data signal used to generate a reduced PAPR time domain data signal. Other aspects and features are also claimed and described.Type: GrantFiled: September 19, 2022Date of Patent: February 27, 2024Assignee: QUALCOMM IncorporatedInventors: Gokul Sridharan, Saeid Sahraei, June Namgoong, Peter Gaal, Krishna Kiran Mukkavilli, Tingfang Ji, Wei Yang
