TRANSMITTER SHARING SYSTEM FOR DUAL ACTIVE SUBSCRIPTIONS

摘要

For a user equipment in a transmitter sharing dual subscriber identity module (SIM) dual active subscriptions (DSDA) mode, a first subscription of a first radio access technology (RAT) in a packet switched data call in general has a lower priority than a second subscription in an active voice call in a second RAT. As a result of this default high priority assigned to the active voice call, the first subscription may experience long delay, low throughput or in some cases radio link failure due to long starvations. A method for wireless communication includes detecting whether an uplink transmission within a frame of the second RAT overlaps at least one time slot of the first RAT. The method also includes prioritizing data of the first RAT by blanking the frame of the second RAT when a number of overlapping slots is above a threshold.

1. A method of wireless communication in a multi subscriber identification module (SIM) user equipment (UE) with multiple active subscriptions sharing a transmit (TX) chain among at least a first radio access technology (RAT) and a second RAT, comprising:
detecting whether an uplink transmission within a frame of the second RAT overlaps at least one time slot of the first RAT; and prioritizing data of the first RAT by blanking the frame of the second RAT when a number of overlapping slots is above a threshold.
