Hybrid automatic repeat request acknowledge resource allocation for enhanced physical downlink control channel

A user equipment (UE), comprising:

• a transceiver;
• a processor connected to the transceiver;
• and
• a memory connected to the processor, the memory storing instructions controlling operation of the processor and the transceiver, the instructions causing the processor and transceiver to:
• receive a control message on a physical downlink control channel (PDCCH);
• receive a second message indicated by the control message;
• determine a physical uplink control channel (PUCCH) resource for transmitting an ACK/NAK signal based on the PDCCH, wherein the PUCCH resource for at least one PDCCH physical resource block set is determined based on a lowest indexed control channel element and a UE-specific offset parameter;
• and
• transmit the ACK/NAK signal on the determined PUCCH resource, the ACK/NAK signal indicating whether the second message was correctly received by the UE.

A user equipment (UE), comprising:

• a transceiver configured to receive a control message on a physical downlink control channel (PDCCH), and to receive a second message indicated by the control message;
• and
• a processor configured to determine a physical uplink control channel (PUCCH) resource for transmitting an ACK/NAK signal based on the PDCCH, wherein the PUCCH resource for at least one PDCCH physical resource block set is determined based on a lowest indexed control channel element and a UE-specific offset parameter,
• wherein the transceiver is further configured to transmit the ACK/NAK signal on the determined PUCCH resource, the ACK/NAK signal indicating whether the second message was correctly received by the UE.

A method comprising:

• receiving, at a user equipment (UE), a control message on a physical downlink control channel (PDCCH);
• receiving, at the UE, a second message indicated by the control message;
• determining, by the UE, a physical uplink control channel (PUCCH) resource for transmitting an ACK/NAK signal based on the PDCCH, wherein the PUCCH resource is determined based on a lowest indexed control channel element and a UE-specific offset parameter;
• and
• transmitting, by the UE, the ACK/NAK signal on the determined PUCCH resource, the ACK/NAK signal indicating whether the second message was correctly received by the UE.
