Methods and apparatus for improving call performance by enabling uplink transmissions during poor downlink radio conditions

摘要

Apparatus and methods of improving call performance by enabling/continuing uplink transmissions during poor downlink radio conditions. The apparatus and methods further include monitoring, by a user equipment (UE), downlink (DL) signal conditions associated with a serving Node B. Moreover, the apparatus and methods include triggering an out-of-sync state upon a determination that the DL signal conditions have degraded beyond a DL signal quality threshold. Additionally, the apparatus and methods include delaying turning off of a power amplifier (PA) associated with transmission of uplink (UL) messages for a call performance improvement threshold time duration.

1. A method of wireless communications, comprising:
monitoring, by a user equipment (UE), downlink (DL) signal conditions associated with a serving Node B; triggering an out-of-sync state upon a determination that the DL signal conditions have degraded beyond a DL signal quality threshold; and delaying turning off of a power amplifier (PA) associated with transmission of uplink (UL) messages for a call performance improvement threshold time duration, wherein the delaying includes setting at least a portion of data radio bearers (RBs) to zero in a radio link control (RLC) layer buffer occupancy (BO) indication while maintaining one or both of a data RB and signaling resource bearer (SRB) for transmission of one or more measurements.
