Publication number: 20240137958Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may support two or more uplink switching periods for transmit chain switching. The UE may transmit a UE capability message indicating the UE capability to support a first uplink switching period and a second uplink switching period for transmit chain switching. The first uplink switching period and the second uplink switching period may each correspond to different switching periods associated with configuration switches between different transmit chain configurations of the UE. The UE and a base station may select an uplink switching period from among the first uplink switching period and the second uplink switching period. The UE may transmit an uplink data message to the base station after a preparation time that is based on the uplink switching period.Type: ApplicationFiled: April 28, 2021Publication date: April 25, 2024Inventors: Yiqing CAO, Peter GAAL, Timo Ville VINTOLA, Alberto RICO ALVARINO, Kazuki TAKEDA, Wanshi CHEN, Bin HAN, Yan LI, Zhimin DU

Patent number: 11646806Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a calibration to improve the accuracy, reliability, or both of signal transmissions.

For example, the UE may determine a calibration offset between a reference time and a calibration gap according to an equation using at least the identifier as input. During the calibration gap, the UE may transmit a calibration signal using one or more antenna ports and may calibrate (e.g., adjust power amplification for) the one or more antenna ports based on an estimated actual transmit power for the calibration signal (e.g., received by other antenna ports of the UE or received by another device).Type: GrantFiled: June 11, 2019Date of Patent: May 9, 2023Assignee: QUALCOMM IncorporatedInventors: Yan Zhou, Tao Luo, Masato Kitazoe, Timo Ville Vintola, Valentin Alexandru Gheorghiu
