Patent number: 11871404Abstract: Aspects relate to techniques for mitigating wireless communication interference. For example, one or more of a cyclic prefix length, a subcarrier spacing, a beam pair, or a frequency domain separation may be changed to mitigate the effects of inter-symbol interference (ISI) at a UE or a base station. A UE may measure a received timing difference between a time at which the UE receives a downlink transmission and a time at which energy from an uplink transmission by the UE is received by the UE. If this received timing difference exceeds a specified duration of time (e.g., the length of a cyclic prefix), the ISI at the UE may increase. In some examples, the interference mitigation techniques described herein may be invoked if there is an increase in the measured received timing difference.Type: GrantFiled: August 19, 2021Date of Patent: January 9, 2024Assignee: QUALCOMM IncorporatedInventors: Qian Zhang, Yan Zhou, Navid Abedini, Tao Luo, Junyi Li
