  • Patent number: 11665586
    Abstract: Provided are a method for data transmission and apparatus. The method includes: receiving configuration information from a base station, the configuration information indicating whether a data packet deletion function is enabled at a PDCP entity corresponding to a preset data bearer. When the data packet deletion function is enabled, a duration for transmission of SDUs is recorded when the SDUs are transmitted from the PDCP entity corresponding to the preset data bearer to a RLC layer. A first SDU that has not yet been transmitted to the RLC layer is determined from the SDUs in a case that the duration for transmission of the SDUs is longer than a preset duration. The first SDU is deleted.

  • Publication number: 20230153058
    Abstract: The various implementations described herein include methods and systems for synchronous audio playback. In one aspect, a method is performed at each of a plurality of electronic devices, each having an audio system, an internal clock, processors and memory storing programs for execution by the processors. Each device is configured for two-way communications with a server and associated with a user account. The device receives an identification of a first device as a common clock device that has a first internal clock being designated as a master clock. The device receives a synchronized audio playback command that includes audio data to be output and a future playback time. In response to receiving the audio data, the device determines a synchronized audio playback time. If the determined synchronized audio playback time has not yet occurred, the electronic device outputs the audio data based on the determined synchronized audio playback time.
