Abstract
A generalized duplexing method, base station (122) and mobile station (118) for TDD operation in a communication system (100) having a primary carrier (310; 410) operating in TDD mode; and at least one secondary carrier (320; 420). The method supports half-duplex and full duplex modes of operation. The primary and secondary carrier may operate at different chip rates. This provides the advantages that generalized duplexing operates on more than one RF carrier, and unlike conventional UTRA FDD mode generalized duplexing does not require a fixed frequency duplex spacing between RF carriers.
