Patent number: 11996927Abstract: Methods, systems, and devices for wireless communications are described. A network may be configured to provide a beam measurement configuration to a UE that indicates durations for monitoring transmission beams, and tuning a component of the UE between the monitoring. The durations may include a first portion that a UE may use for a tuning operation and a second portion that the UE may use to monitor for or measure a respective reference signal. In various examples, the indicated durations may include a third portion that the UE may use for another tuning operation, or the durations may overlap with one another during an overlap duration that the UE may use for another tuning operation. During the indicated durations, the network may refrain from transmitting other downlink data or control information for the UE, and the UE may refrain from monitoring for such other downlink data or control information.Type: GrantFiled: July 29, 2021Date of Patent: May 28, 2024Assignee: QUALCOMM IncorporatedInventors: Liangping Ma, Xiao Feng Wang, Ayan Sengupta, Peter Gaal, Alberto Rico Alvarino, Bharat Shrestha, Umesh Phuyal, Jun Ma, Dan Zhang

Publication number: 20240089023Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may operate by asynchronously transmitting code division multiple access (CDMA) uplink signals to a network entity. The UE may transmit the CDMA signals via an uplink channel that may be shared with orthogonal frequency multiplexing (OFDM) signaling transmitted by one or more other UEs. The UE may indicate to the network entity a capability for communicating with CDMA waveforms and may use CDMA waveforms based on transmitting the indication. The UE may also receive one or more parameters associated with using the CDMA waveforms, and may use CDMA waveforms based on the one or more parameters. The uplink channel may be a random access channel (RACH) and may support RACH transmissions, or may be a data channel and support data transmissions.Type: ApplicationFiled: September 13, 2022Publication date: March 14, 2024Inventors: Jun Ma, Danlu Zhang, Qiang Wu, Lianghai Ji, Liangping Ma, Huilin Xu, Mohamad Sayed Hassan, Karthik Anantha Swamy, Weimin Duan

Patent number: 9578287Abstract: The disclosure provides a method, device and system for teleconference information insertion. The method includes: a valid insertion content is acquired according to a stored insertion content after an conference insertion request is detected, and a real-time content of a conference is switched to the valid insertion content. Thus, a purpose of information insertion in a conference is achieved by pre-storing an insertion content before or during the conference, then acquiring a valid insertion content according to the stored insertion content after a conference insertion request is detected during the conference and finally switching the real-time content of the conference to the insertion content, thereby enhancing the effect of the conference.Type: GrantFiled: August 30, 2013Date of Patent: February 21, 2017Assignee: ZTE CORPORATIONInventors: Xin Tong, Fu Wang, Liangping Zhang
