Abstract
The present disclosure describes embodiments of apparatuses, systems, and methods for that include and apply an association between one or more first antenna ports that carry Enhanced Physical Downlink Control Channel (EPDCCH) data and one or more second antenna ports that carry Physical Downlink Shared Channel (PDSCH) data in connection with machine type communications.

1-23. canceled
A network node apparatus comprising:
- control circuitry to obtain association information that includes an association between one or more first antenna ports that carry Enhanced Physical Downlink Control Channel (EPDCCH) data and one or more second antenna ports that carry Physical Downlink Shared Channel (PDSCH) data;
- and
- transmit circuitry in communication with the control circuitry to:
- transmit the association information to a Machine Type Communication (MTC) User Equipment (UE),
- transmit, to the MTC UE, EPDCCH data via at least one of the one or more first antenna ports during a first sub-frame, the EPDCCH data to schedule PDSCH data in a second sub-frame that is after the first sub-frame, and
- transmit, to the MTC UE, the PDSCH data via at least one of the one or more second antenna port during the second sub-frame.
One or more computer-readable media having instructions that, when executed, cause a network node to:
- obtain association information that includes an association between one or more first antenna ports to be used to transmit Enhanced Physical Downlink Control Channel (EPDCCH) data and one or more second antenna ports to be used to transmit Physical Downlink Shared Channel (PDSCH) data;
- transmit the association information to plural Machine Type Communication (MTC) User Equipment (UE),
- transmit, to the MTC UE, EPDCCH data via at least one of the one or more first antenna ports during a first sub-frame, the EPDCCH data to schedule PDSCH data in a second sub-frame that is after the first sub-frame, and
- transmit, to the MTC UE, the PDSCH data via at least one of the one or more second antenna port during the second sub-frame.
An apparatus comprising:
- control circuitry to store association information that includes an association between one or more first antenna ports that carry Enhanced Physical Downlink Control Channel (EPDCCH) data and one or more second antenna ports that carry Physical Downlink Shared Channel (PDSCH) data;
- and
- transmit circuitry to transmit to a Machine Type Communication (MTC) User Equipment (UE), in accordance with the association information, EPDCCH data via at least one of the one or more first antenna ports during a first sub-frame, the EPDCCH data to schedule PDSCH data in a second sub-frame that is after the first sub-frame, and transmitting, to the MTC UE, the PDSCH data via at least one of the one or more second antenna ports during the second sub-frame.
One or more computer-readable media having instructions that, when executed, cause a Machine Type Communication (MTC) User Equipment (UE) to:
- receive an association between one or more first antenna ports that carry Enhanced Physical Downlink Control Channel (EPDCCH) data and one or more second antenna ports that carry Physical Downlink Shared Channel (PDSCH) data;
- receive EPDCCH data via at least one of the one or more first antenna ports during a first sub-frame, the EPDCCH data to schedule PDSCH data in a second sub-frame that is after the first sub-frame, and
- infer from the EPDCCH data received via least one of the one or more first antenna ports a channel over which the PDSCH data is to be transmitted via the at least one of the one or more second antenna ports during the second sub-frame.
