US 2019/0200352 A1 · GRANT-FREE DOWNLINK TRANSMISSION

Abstract

Methods, systems, and devices for wireless communications are described. The described techniques generally support downlink transmissions. For example, a user equipment (UE) may receive a resource configuration for reception of a downlink transmission within a repetition window, the resource configuration including an indicator of a repetition window size for the downlink transmission. The UE may monitor, according to the resource configuration, one or more transmission time intervals (TTIs) of the repetition window for reception of the downlink transmission. In some cases, the downlink transmission may be a grant-free downlink transmission. Here, the UE may attempt to decode the grant-free downlink transmission during the one or more TTIs based at least in part on the repetition window size. Using the described techniques, the UE may efficiently determine one or more decoding parameters for the grant-free downlink transmission, thereby providing benefits in terms of latency reduction, power consumption, etc.
