UPLINK CARRIER AGGREGATION AND SIMULTANEOUS MIMO WITHOUT MID-BAND AND HIGH-BAND SWITCH COMBINING

Abstract:

Described herein are front-end architectures and wireless devices that support uplink carrier aggregation and simultaneous MIMO operations in a plurality of band combinations. The front-end architectures include a combination of low-band, mid-band, high-band, MIMO, and uplink carrier aggregation modules to provide the described functionality. The architectures include an antenna switch module coupled to a first antenna and to a second antenna. The architectures do not use mid-band and high-band switch combining. The architectures use low-band filters in diplexers or triplexers positioned before an antenna switch module.
