The researchers get payed very well, but what (to those I met) was even more important: they get all the assistance they want, plus 1. As one of them told me "I hate doing things twice. I now do not have to. I think of something, try to get it to work and I am done. The grinding is done for me." A truly very nice environment to do research in, with a boatload of resources at their fingertips.
Just check the number of patents Huawei [0] holds.
