Patent number: 11832258Abstract: When a base station is capable of using multiple different types of waveforms for a downlink communication to a UE, the UE may waste processing resources attempting to receive and/or process the downlink communication. For example, the UE may cycle through various possible types of waveforms in an attempt to process the downlink communication. Techniques described herein use waveform signaling for downlink communications to notify the UE of a type of waveform being used for a downlink communication, thereby conserving UE resources (e.g., processing resources, memory resources, RF resources, and/or the like) that would otherwise be wasted attempting to process the downlink communication using multiple types of waveforms.Type: GrantFiled: April 30, 2020Date of Patent: November 28, 2023Assignee: QUALCOMM IncorporatedInventors: Tao Luo, Jing Sun, Sony Akkarakaran, Tamer Kadous, Xiao feng Wang, Akula Reddy

Patent number: 11637730Abstract: Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.Type: GrantFiled: January 15, 2021Date of Patent: April 25, 2023Assignee: QUALCOMM IncorporatedInventors: Sungwoo Park, Wooseok Nam, Tao Luo, Jing Sun, Xiaoxia Zhang, Zhifei Fan, Arumugam Chendamarai Kannan, Akula Reddy, Ahmed Abdelaziz Ibrahim Abdelaziz Zewail

Patent number: 11601253Abstract: A wireless communication system utilizes a synchronization signal block (SSB) structure to enable beam switching at higher sub carrier spacing (SCS) or uplink transmissions within an SSB. The SSB structure has a first SCS for an SSB transmission and a second SCS for a data transmission. The SSB structure is based on the first SCS and the second SCS, with the SSB structure including at least one gap between SSB symbols or between SSBs. The wireless communication system transmits or receives an SSB based on the SSB structure. A base station may transmit a downlink signal during the gap, for example, where the second SCS is much greater than the first SCS. A user equipment may transmit an uplink signal such as an acknowledgment during the at least one gap. The user equipment or the base station may perform analog beam switching during the at least one gap between SSBs.Type: GrantFiled: November 18, 2020Date of Patent: March 7, 2023Assignee: QUALCOMM IncorporatedInventors: Akula Reddy, Jing Sun, Tao Luo, Xiaoxia Zhang, Srinivas Yerramalli, Ahmed Abdelaziz Ibrahim Abdelaziz Zewail, Zhifei Fan, Sungwoo Park, Wooseok Nam

Patent number: 11502811Abstract: Subcarrier spacing (SCS) for data may be adapted or dynamically configured based on the occurrence or presence of a synchronization signal block (SSB) transmission. For example, during a SSB transmission, the SCS of data may be automatically switched from some default data SCS to a second SCS (e.g., the SCS of the SSB) to allow for frequency division multiplexing (FDM) of data and SSB where the data and SSB use the same numerology. As such, communicating devices (e.g., a base station and a user equipment (UE)) may identify some location or configuration for a SSB, and may determine a second subcarrier spacing (e.g., a subcarrier spacing associated with the SSB) such that the SCS of data may be adapted to the second subcarrier spacing during the FDM of the SSB and the data. The SSB and data may thus be contemporaneously transmitted or received using the second SCS.Type: GrantFiled: September 14, 2020Date of Patent: November 15, 2022Assignee: QUALCOMM IncorporatedInventors: Sungwoo Park, Jing Sun, Wooseok Nam, Tao Luo, Xiaoxia Zhang, Zhifei Fan, Akula Reddy, Ahmed Abdelaziz Ibrahim Abdelaziz Zewail, Srinivas Yerramalli

Patent number: 11063800Abstract: Aspects of the disclosure relate to synchronization signaling supporting multiple waveforms. A synchronization signal block (SSB) is configurable for transmission using either at least a first waveform or a second waveform, where the first waveform has higher peak to average power ratio (PAPR) characteristics such as OFDM and the second waveform has lower PAPR characteristics, such as DFT-S-OFDM. The SSB is transmitted selectively using either the first waveform or the second waveform for transmission of the SSB. Furthermore, the characteristics of the transmission such as a predetermined pattern of the first and second waveform transmissions may be utilized to communicate to a receiver the type of waveform being used. In this manner, SSB transmissions may take advantage of respective advantages afforded by each type of waveform, particularly when using higher frequency transmissions above 40 GHz in wireless communication systems.Type: GrantFiled: March 26, 2018Date of Patent: July 13, 2021Assignee: QUALCOMM IncorporatedInventors: Sony Akkarakaran, Tao Luo, Jing Sun, Rahul Malik, Tamer Kadous, Akula Reddy
