Abstract
This document describes systems and techniques directed at concurrent communication in multiple time-division duplex (TDD) bands. As new industry standards (e.g., the Fifth Generation New Radio (5G NR) standard) are being implemented, more TDD bands are becoming available for wireless communications. Generally, manufacturers will add additional antenna systems for each TDD band, but this method may become costly and need extra space, which is already limited, within the user device In various aspects, the concurrent communication system includes a radio frequency (RF) modem module configured to operate on multiple TDD bands, which may include bands that are located near each other on the RF spectrum. The concurrent communication system further includes transceiver circuitry with at least one transmission chain and at least four reception chains. The architecture of this system offers an efficient and inexpensive way to communicate on at least two TDD bands concurrently with reduced hardware cost.
