Simultaneous LTE data and DSDA voice

A method for performing data transmission in a user equipment device (UE), wherein the UE comprises at least two subscriber identity modules (SIMs) and at least two radios, the method comprising:

• concurrently conducting a first voice call on a first radio of the UE and a second voice call on a second radio of the UE;
• performing a first data communication on the first radio while the first voice call is on hold and the second voice call is not on hold;
• after performing the first data communication, performing a second data communication on the second radio while the second voice call is on hold and the first voice call is not on hold;
• receiving a request to perform a third data communication during the concurrently conducting the first voice call and the second voice call, while neither the first voice call nor the second voice call is currently on hold;
• and
• in response to the request, dynamically selecting available slots from the first radio and the second radio for performing the third data communication, while neither the first voice call nor the second voice call is currently on hold.

A user equipment device (UE) configured to perform data transmission, comprising:

• a first radio;
• a second radio;
• one or more processors coupled to the first radio and the second radio, wherein the one or more processors are configured to:
• concurrently conduct a first voice call via the first radio and a second voice call via the second radio;
• perform a first data communication via the first radio while the first voice call is on hold and the second voice call is not on hold;
• perform a second, subsequent data communication via the second radio while the second voice call is on hold and the first voice call is not on hold;
• receive a request to perform a third data communication during the concurrently conducting the first voice call and the second voice call, while neither the first voice call nor the second voice call is currently on hold;
• and
• in response to the request, dynamically select available slots from the first radio and the second radio for performing the third data communication, while neither the first voice call nor the second voice call is currently on hold.

A user equipment device (UE) configured to perform data transmission, comprising:

• one or more processors configured to:
• concurrently conduct a first voice call via a first radio and a second voice call via a second radio, wherein the first voice call is supported by a first subscriber identity module (SIM), and the second voice call is supported by a second SIM;
• receive a request to perform a data communication during the conducting the first voice call and the second voice call;
• determine whether one of the first voice call or the second voice call is currently on hold after the receiving the request to perform the data communication;
• in response to determining that the first voice call is on hold, perform the data communication via the first radio while the first voice call is on hold;
• and
• in response to determining that the second voice call is on hold, perform the data communication via the second radio while the second voice call is on hold;
• wherein the data communication is supported by one of the first SIM and the second SIM.
