Patent number: 11943176Abstract: Methods, systems, and devices for wireless communications are described. A repeater extends coverage of wireless communications services between two wireless nodes (a base station and a user equipment (UE)). A network control node (e.g., a base station) receives a first indication of a capability of a repeater to detect a time division duplexing (TDD) pattern of a channel between the base station and the UE. The base station transmits, to the UE and via the repeater, one or more parameters associated with the UE performing one or more channel measurements and reference signals for the channel measurements. The base station transmits, to the repeater, a second indication of a TDD pattern of the channel based on the capability of the repeater. Based on the indication of the TDD pattern, the repeater adjusts one or more radio frequency components of the repeater.Type: GrantFiled: June 15, 2021Date of Patent: March 26, 2024Assignee: QUALCOMM IncorporatedInventors: Jianghong Luo, Navid Abedini, Junyi Li, Tao Luo
