Methods, systems, and devices for wireless communication are described in which scheduling of time and frequency resources for multiple component carriers (CCs) may be provided in a low latency physical downlink control channel (sPDCCH) transmission to a user equipment (UE). The scheduling information may include a first portion that is transmitted during a first transmission time interval (TTI) and that includes scheduling information (UE-specific or common for multiple UEs) for two or more shortened TTIs (sTTIs) on one or more CCs, and a second portion that may be specific to the particular sTTI on one or more CCs. Rate matching information may be provided to indicate portions of the sPDCCH that may be reallocated for shared channel transmissions. The scheduling information may be, in some cases, provided in a single-level scheduling information transmission for two or more UEs, that provides UE-specific resources on one or more CCs.
