Performing data communication using a first RAT while performing a voice call using a second RAT

摘要

Performing data communication using a first radio access technology (RAT) while performing a voice call using a second RAT, using a first radio (e.g., a single radio for cellular communication. The UE may use the first radio to initially perform first data communication using the first RAT. During the first data communication the UE may not be communicating using the second RAT or may not generally maintain a connection to the second RAT. Subsequently, the UE may receive an indication to perform at least one of a mobile originated voice call or receive a mobile terminated voice call using the second RAT. Accordingly, the UE may perform the voice call using the second RAT in response to the indication, using the first radio. Additionally, the UE may perform second data communication using the first RAT during the voice call, using the first radio.

1. A method, comprising:
at a user equipment device (UE) comprising a first radio, wherein the first radio comprises one or more receive chains, where the one or more receive chains operate on the same frequency, and wherein the first radio is configurable to communicate using a first radio access technology (RAT) and a second RAT:
performing, using the first radio, first data communication using the first RAT, wherein the first RAT comprises long term evolution (LTE), wherein during said performing first data communication the UE is not communicating using the second RAT, wherein the UE comprises a single SIM for the first RAT and the second RAT;receiving an indication to perform at least one of a mobile originated voice call or receive a mobile terminated voice call using the second RAT;performing, using the first radio, the voice call using the second RAT in response to the indication;performing, using the first radio, second data communication using the first RAT during said performing the voice call, wherein the second data communication involves transmission and reception using the first radio, and wherein the one or more receive chains time multiplex among the first and second RATs;wherein, based on the UE performing the second data communication during the voice call, the UE is configured to perform the voice call using the second RAT using fewer frames at an increased power, and wherein performing the voice call using fewer frames at the increased power allows the UE to use an additional frame of the second RAT for performing the second data communication.
