Systems and methodologies are described that facilitate transmitting and receiving signals over I and Q branches of a communication channel to mitigate potential UQ imbalance. In particular, a device can transmit a signal over the I and Q branches to distribute transmission power substantially evenly for a given channel. The device can demodulate the data with a code or matrix having real and complex modifiers resulting in an I and Q branch signal for transmission. Where the channel has multiple resources, the device can alternate or transmit over the I branch in one resource and the Q branch in another resource for a given signal to distribute power. Also, the device can apply a complex scrambling code to distribute a signal over both the I and Q branches. The device can also use QPSK or higher order modulation to send the signals meant for the same user.

Linvention concerne des systèmes et méthodologies qui facilitent la transmission et la réception des signaux sur des branches I et Q dun canal de communication pour atténuer un équilibre I/Q potentiel. En particulier, un dispositif peut transmettre un signal sur les branches I et Q pour distribuer la puissance de transmission de manière sensiblement régulière pour un canal donné. Le dispositif peut démoduler les données avec un code ou une matrice ayant des modificateurs réels et complexes conduisant à un signal de branche I et Q pour transmission. Lorsque le canal a de multiples ressources, le dispositif peut alterner ou transmettre sur la branche I dans une ressource et la branche Q dans une autre ressource pour un signal donné pour distribuer la puissance. De même, le dispositif peut appliquer un code dembrouillage complexe pour distribuer un signal sur les deux branches I et Q. Le dispositif peut également utiliser un QPSK ou une modulation dordre supérieur pour envoyer les signaux destinés au même utilisateur.
