Abstract
Techniques for supporting data transmission and reception on multiple bands for carrier aggregation are disclosed. In an exemplary design, an apparatus (e.g., a wireless device) includes first and second antenna interface circuits coupled to first and second antennas, respectively. The first antenna interface circuit includes a first quadplexer for first and second bands. The second antenna interface circuit includes a second quadplexer for the first and second bands. The first quadplexer may be a duplicate of the second quadplexer, which may simplify implementation. Each antenna interface circuit may further include a diplexer, a duplexer, a triplexer, another quadplexer, switches, etc. The first and second quadplexers may support data transmission and reception on two bands in a first band group. Other circuits in the first and second antenna interface circuits may support data transmission and/or reception on additional bands, possibly in one or more other band groups.
