FTC.gov:

The FTC has charged Qualcomm with violating the FTC Act. The complaint alleges that Qualcomm:

* Maintains a “no license, no chips” policy under which it will supply its baseband processors only on the condition that cell phone manufacturers agree to Qualcomm’s preferred license terms. The FTC alleges that this tactic forces cell phone manufacturers to pay elevated royalties to Qualcomm on products that use a competitor’s baseband processors. According to the Commission’s complaint, this is an anticompetitive tax on the use of rivals’ processors. “No license, no chips” is a condition that other suppliers of semiconductor devices do not impose. The risk of losing access to Qualcomm baseband processors is too great for a cell phone manufacturer to bear because it would preclude the manufacturer from selling phones for use on important cellular networks.

It sounds like Qualcomm is demanding to be paid more by the phone manufacturer for access to Qualcomm's patented radios if they use processors from the other manufacturer. If so, that's clearly anti-competitive (especially in a cut-throat business like cell phones), just as MS's per-processor tax for access to Windows at cut-rate prices was anti-competitive.

HTH.
