Why not similarly have HSUPA where U stands for uplink?
3GPP is working towards HSUPA as well but there are no clear details yet. Theoretically HSUPA is suppose to boost the uplink speed to 3.5Mbps. And it dosent stop here. There are further plans to introduce HSOPA where O stands for OFDM (orthogonal frequency division multiplexing). This will increase the download capacity to 40Mbps.
