  • Patent number: 11910363
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish multiple wireless connections, such as a wireless connection for a first subscriber identity module (SIM) and a wireless connection for a second SIM, that share time-frequency resources. The UE may communicate data packets with another device during a communication session on the wireless connection for the first SIM. The UE may determine to pause the communication session for a duration based on receiving an indication from the other UE or based on a user input to pause communication. The UE may communicate data packets on the wireless connection for the second SIM for at least a portion of the duration using the shared time-frequency resources based on pausing the communication session.

  • Patent number: 11546396
    Abstract: Disclosed are techniques for communication. In an aspect, a communications devices communicates, from an upper communication layer (e.g., application layer) to a lower communication layer (e.g., transport layer), indication(s) to prioritize certain frames (e.g., recovery frames and/or feedback frames) over other frames (e.g., Inter frames) associated with the same QCI bearer for a video streaming session. The lower communication layer may place the prioritized frames ahead of the non-prioritized frames in a lower layer transmission buffer based on the indication. The communications device may transmit one or more packets carrying the first set of frames before one or more packets carrying the second set of frames based on the first set of frames being placed ahead of the second set of frames in the lower layer transmission buffer.
