Abstract:
Methods, systems, and devices for wireless communications are described to enable base station and a user equipment (UE) to mitigate interference when using full-duplex communications. For example, a base station communicating with a UE via full-duplex communications may indicate for the UE to align the time of its uplink transmissions with the time the UE receives downlink transmissions. Additionally or alternatively, the base station may indicate a timing alignment window for the UE, where the window may consist of an allowed time period the UE may use to select a time to begin uplink transmissions. In some examples, the base station may select a cyclic prefix for full-duplex communications, where the cyclic prefix may be longer than a cyclic prefix used for other communications. Further, the base station may select uplink frequency and downlink frequency bands separated by a defined guard band for full-duplex communications.
