Abstract:
Downlink control information techniques for wireless communications with shorter TTI (S-TTI) length are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode signaling indicating a duration of a time window, the time window comprising a plurality of S-TTIs forming a single TTI. Absence of a discontinuous reception (DRX) indicator is detected within control information received within a first S-TTI of the plurality of S-TTIs. Upon detecting the absence of the DRX indicator within received control information, a S-PDCCH within each of the plurality of S-TTIs is monitored during the duration. Scheduling information received via the S-PDCCH within one of the plurality of S-TTIs is decoded, and data is encoded for transmission on a shared data channel based on the scheduling information.
