In one aspect, a first device may report to the second device that the first device is using either a same DOF for communications in different transmission directions or different DOFs for the different transmission directions. Based on the reported DOF(s), the second device may use beam correspondence-based beam relationships on the different transmission directions if the DOFs are the same and resource block allocations for the communications in both transmission directions are closely matched in frequencies. Alternatively, if the DOFs are different for the different transmission directions, the second device may adjust either a codebook parameter or may use an appropriate antenna panel. Additionally, or alternatively, the second device may direct the first device to use respective antenna subarrays with similar DOFs. | 2022-05-26 |
20220166597 | MILLIMETER-WAVE FULLY-INTEGRATED FULL DUPLEXER MODULES WITH AND WITHOUT INTERNAL LOW NOISE AMPLIFIER AND POWER AMPLIFIER FOR 5G APPLICATIONS - Architectures of millimeter-wave (mm-wave) fully-integrated frequency-division duplex (FDD) transmitting-receiving (T/R) front-end (FE) modules include a duplexer (DUX), power amplifier (PA), and low noise amplifier (LNA) on a single semiconductor substrate to facilitate the development of system on a chip (SoC) for mm-wave 5th Generation (5G) wireless communications applications. The first FE module adopts a passive DUX consisting of Wilkinson power divider and ground-center-tap transformer to achieve high isolation between PA output and LNA inputs. Another FE module combines the advantages of passive DUX and power-efficient cancellation circuits to accomplish high TX-RX isolation and low noise performance at the same time. The DUX can stand alone as a single unit in a system and is used together with external PA and LNA provided in the system, or it can include its own internal PA and LNA to form a DUX FE module. | 2022-05-26 |
