Method and apparatus for enhancing high data rate uplink operations

摘要

A method and apparatus for enhancing uplink operations in a CDMA system is provided. The method may include receiving a rate control value and a transmit power value from a node B, wherein the rate control value is determined through uplink scheduling by the node B, and wherein the transmit power value is selected by the node B to maintain a signal to interference plus noise (SINR) metric within a threshold for a pilot channel, transmitting control channel information at a first power level determined from the transmit power value, and using a first average power tracking unit to generate the first selected transmit power and transmitting data channel information at a second power level determined from both the rate control value and the transmit power value.

1. A method of enhanced uplink operations, comprising:
receiving a power control command from a node B, wherein the power control command is selected by the node B to maintain a signal to interference plus noise (SINR) metric within a dynamic threshold for a pilot channel; transmitting pilot channel information at a pilot channel power adjusted from a first pilot channel power level to a second pilot channel power level that is determined according to the power control command, wherein the second pilot channel power level is higher or lower than the first pilot channel power level; and transmitting data channel information at a data channel power adjusted from a first data channel power level to a second data channel power level that is determined according to the power control command, wherein the second data channel power level is the same or lower than the first data channel power level, and the pilot channel power and data channel power are decoupled.
