Abstract (en)
[origin: WO2016122756A1] Devices and methods of using a fractional subframe are generally described. User equipment may communicate with an evolved NodeB (eNB) using carrier aggregation having carriers in a Long Term Evolution (LTE) licensed spectrum and carriers in an unlicensed spectrum. The UE may receive a (enhanced) physical downlink control channel ((e)PDCCH) formed in accordance with a Downlink Control Information (DCI) format that schedules a physical downlink shared channel (PDSCH) in the fractional subframe and subsequently receive the PDSCH. The (e)PDCCH may be provided in a first full subframe of the LTE licensed spectrum after the fractional subframe, in a full subframe of the LTE licensed spectrum overlapping the fractional subframe, or in the fractional subframe when a threshold number of Orthogonal Frequency Division Multiplexed (OFDM) symbols is in the fractional subframe. The PDSCH may be scaled based on the number of OFDM symbols in the fractional subframe or a PDSCH rank.
