Weighted open loop power control transmitter

摘要

A weighted open loop power control transmitter for controlling transmission power levels using a spread spectrum time division duplex (TDD) technique having frames with timeslots for communication includes a demodulator configured to receive a transmitted signal from the receiver, a channel estimation device, a data estimation device, and a weighted open loop power controller. The weighted open loop power controller includes a power measurement device, a pathloss estimation device configured to receive an interpreted power level from the data estimation device and estimate the pathloss and update a long term average of the pathloss, a quality measurement device, and a transmit power calculation device for determining the transmitter's power level and to control the receiver's amplifier.

1. A user equipment comprising:
at least one component configured to receive a downlink signal in a first time interval and transmit an uplink signal in a second time interval; wherein the first time interval and the second time interval are separated by a plurality of time intervals; wherein the first time interval and the second time interval each include at least one slot, and the plurality of time intervals includes at least one slot; wherein the at least one component is further configured to determine a transmit power level of the uplink signal by multiplying a pathloss by a parameter; wherein the pathloss is derived from a received power level of a reference signal; wherein the parameter is based on a number of slots in the plurality of time intervals separating the first time interval and the second time interval, and wherein the parameter has a value from 0 to 1.
