1. An evolved Node B (eNB) comprising:
- allocation circuitry to;
allocate, in association with transmission to a user equipment (UE), a plurality of downlink regions associated with machine-type communication (MTC); and
allocate, in association with reception from the UE, one or more uplink regions associated with MTC; and
scheduling circuitry, coupled with the allocation circuitry, the scheduling circuitry to;
determine the one or more uplink regions are fewer in number than the plurality of downlink regions; and
identify, based on the determination that the one or more uplink regions are fewer in number than the one or more downlink regions, one or more parameters associated with one or more resources to be used for communication of hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK) feedback between the eNB and the UE.

Abstract
Embodiments described herein relate generally to a communication between a user equipment (UE) and an evolved Node B (eNB). An eNB may allocated uplink and downlink regions associated with machine-type communication (MTC) to a UE. The allocation of uplink and downlink regions may be asymmetric. The eNB may identify parameters based on this asymmetric region allocation to avoid resource collision during communication of hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK) feedback between the eNB and the UE. Other embodiments may be described and/or claimed.

11. A user equipment (UE) comprising:
-
communications circuitry to; process allocation information, received from an evolved Node B (eNB), that is to indicate; a plurality of downlink regions associated with machine-type communication (MTC); one or more uplink regions associated with MTC, the uplink regions to be fewer in number than the plurality of downlink regions; and one or more parameters associated with one or more resources to be used for communication of hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK) feedback between the eNB and the UE; and acknowledgement generation circuitry, coupled with the communications circuitry, to; identify one or more resources based on the one or more parameters, the one or more resources to be used on a channel for HARQ ACK or NACK feedback to avoid resource collision associated with the allocation of the fewer uplink regions than the downlink regions; and cause, in association with data received from the eNB, transmission of HARQ ACK or NACK feedback using the one or more identified resources. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. One or more non-transitory computer-readable media comprising computing device-executable instructions, wherein the instructions, in response to execution by an evolved Node B (eNB), cause the eNB to:
-
allocate, in association with transmission to a user equipment (UE), one or more downlink regions associated with machine-type communication (MTC); allocate, in association with reception from the UE, a plurality of uplink regions associated with MTC; determine the plurality of uplink regions are greater in number than the one or more downlink regions; identify, based on the determination that the plurality of uplink regions are greater in number than the one or more downlink regions, one or more parameters associated with one or more resources on which hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK) feedback is to be transmitted from the eNB to the UE; cause transmission of one or more parameters to the UE; and cause, in association with reception of data from the UE, transmission of HARQ ACK or NACK feedback to the UE on the one or more resources of a physical hybrid automatic repeat request channel (PHICH). - View Dependent Claims (19, 20, 21)

22. One or more non-transitory computer-readable media comprising computing device-executable instructions, wherein the instructions, in response to execution by a user equipment (UE), cause the UE to:
-
process allocation information, received from an evolved Node B (eNB), that is to indicate; one or more downlink regions associated with machine-type communication (MTC); a plurality of uplink regions associated with MTC, the plurality of uplink regions to be greater in number than the one or more downlink regions; and one or more parameters associated with one or more resources to be used for communication of hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK) feedback between the eNB and the UE; identify, in association with the allocation of the greater number of uplink regions than the downlink regions, one or more resources based on the one or more parameters, the one or more resources to be used for HARQ ACK or NACK feedback to avoid resource collision associated with the allocation of the greater number of uplink regions than the downlink regions; and detect, in association with data transmitted to the eNB, reception of HARQ ACK or NACK feedback through a physical hybrid automatic repeat request channel (PHICH) using the identified one or more resources. - View Dependent Claims (23, 24, 25)
