  • Publication number: 20240089023
    Abstract: 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.

  • Patent number: 10715822
    Abstract: An image encoding method includes: determining N P-frames from a sequence of images, N being a positive integer; for each P-frame, determining a source refreshing region in the P-frames, the source refreshing region being a portion less than a whole region of the P-frame; obtaining reconstructed images corresponding to the source refreshing regions by performing a first encoding on the source refreshing regions; obtaining updated P-frames by updating the source refreshing regions with the reconstructed images; and performing a second encoding on the updated P-frames.

  • Patent number: 9578287
    Abstract: 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.
