Systems, methods and apparatus for radio uplink power control

摘要

In some implementations of the present invention, improvement of connection quality and reduction of dropped connection rate are achieved by suspending the transmission of High Speed Dedicated Physical Control Channel (HS-DPCCH) data when a wireless terminal detects a power limiting mode during multi-radio access bearer (MRAB) connections and voice RAB is present, and correspondingly increasing uplink transmission power to voice and signaling data channels. In some implementations, the suspension of HS-DPCCH data can be complete or partial. When fully suspended, no data is sent on the HS-DPCCH. When partially suspended, no channel quality indicator (CQI) is transmitted. In both partial and full suspension schemes, the CQI transmission is suspended until the terminal detects that entry conditions to this state has been terminated.

主权项

1. A method of wireless communication in a voice and data communication, comprising:
establishing an uplink radio bearer channel prior to a power limited mode; detecting, in a wireless terminal, the power limited mode based on a condition of the wireless terminal being met, the condition being met when the wireless terminal transmits at a current transmission power that is less than a maximum transmission power of the wireless terminal by less than a threshold; suspending transmission of at least a portion of uplink control data on at least one uplink channel at the wireless terminal when the power limited mode is detected, for an entire duration of the detected power limited mode, wherein the uplink radio bearer channel is sustained during said suspending.
