Downlink channel design for LTE with low latency

A method of managing user equipment (UE) communications in a wireless communications system, comprising:

• obtaining, at a network entity, user data for transmission to one or more user equipment UEs on a downlink channel;
• determining one or more delivery constraints associated with at least one of the user data and the one or more UEs;
• and
• generating, based on the user data for transmission and the one or more delivery constraints, a downlink subframe data structure for allocating downlink channel resources for transmission of the user data for transmission, wherein the downlink subframe data structure comprises:
• a downlink subframe comprising two slots and including one or more quick downlink channels having a single-slot transmission time interval (TTI);
• one or more resource element blocks each comprising one or more resource elements into which a frequency bandwidth is divided within one or both of the two slots, wherein each of the one or more resource element blocks comprises a control channel region or a data channel region corresponding to the one or more quick downlink channels, and wherein at least the control channel region is multiplexed, within at least one symbol, with a legacy control channel region;
• and
• one or more resource grants, located within one or more control channel regions, related to one or more data channel regions for the one or more UEs served by the one or more quick downlink channels.

An apparatus for managing user equipment (UE) communications in a wireless communications system, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory stores processor-executable instructions, that when executed by the processor, cause the processor to:
• obtain, at a network entity, user data for transmission to one or more UEs on a downlink channel;
• determine one or more delivery constraints associated with at least one of the user data and the one or more UEs;
• generate, based on the user data for transmission and the one or more delivery constraints, a downlink subframe data structure for allocating downlink channel resources for transmission of the user data for transmission, wherein the downlink subframe data structure comprises:
• a downlink subframe comprising two slots and including one or more quick downlink channels having a single-slot transmission time interval (TTI);
• one or more resource element blocks each comprising one or more resource elements into which a frequency bandwidth is divided within one or both of the two slots, wherein each of the one or more resource element blocks comprises a control channel region or a data channel region corresponding to the one or more quick downlink channels, and wherein at least the control channel region is multiplexed with a legacy control channel region;
• and
• one or more resource grants, located within one or more control channel regions, related to one or more data channel regions for the one or more UEs served by the one or more quick downlink channels.
