Abstract: Devices and methods of reducing overall Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) of user equipment (UE) using a large amount of carrier aggregation are generally described. The UE may receive a subframe from an enhanced NodeB (eNB). The subframe may contain a physical downlink control channel (PDCCH) formed in accordance with a Downlink Control information (DCI) format. The DCI format may comprise a Downlink Assignment Index (DAI) for Time Division Duplexed (TDD) and Frequency Division Duplexed (FDD) operation. The UE may determine, dependent on the DAI, a number and ordering of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) bits to be transmitted on a Physical Uplink Shared Channel (PUSCH) and subsequently transmit the HARQ-ACK bits.

Abstract: Briefly, in accordance with one or more embodiments, an apparatus may be configured to receive a first scheduling request transmission for a first cell group, and a second scheduling request transmission for a second cell group, determine one of the first scheduling request and the second scheduling request to have a higher priority and another one of the first scheduling request and the second scheduling request to have a lower priority, and process the scheduling request having a higher priority without processing the scheduling request having a lower priority. An apparatus may be configured to combine a configuration of a first scheduling request for a first cell group and a second configuration of a second scheduling request for a secondary cell group in a system radio bearer, and transmit the SRB to a user equipment to process the first scheduling request and the second scheduling request.

Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), and methods are described for generating an extended power headroom report (ePHR) based on an uncertainty associated with a physical downlink control channel communication granting an uplink grant for a physical uplink shared channel communication when the system is configured for simultaneous physical uplink shared channel and physical uplink control channel communications. Some embodiments are structured to generate the ePHR using a type 2 report regardless of the uncertainty associated with the ePHR, while other embodiments generate the ePHR using a reference format. In some embodiments, a UE communicates a timing field with a UE capability communication indicating whether the UE meets timing requirements to avoid uncertainty in ePHR communications.

Abstract: A user equipment (UE) includes a transmission mode component, a selection component, and a transmission component. The transmission mode component is configured to selectively allocate resources for device-to-device communication according to a plurality of transmission modes. The plurality of transmission modes include a first transmission mode in which the resources used by the UE are specifically allocated by one of a base station or relay node and a second transmission mode in which the UE selects the resources from a pool of available resources. The selection component is configured to select a selected transmission mode. The transmission component is configured to transmit signals in frequency resources selected according to the selected transmission mode.

Abstract: Embodiments of a machine-type communication (MTC) User Equipment (UE) and methods for configuring a MTC UE using an evolved Node B (eNB) are generally described herein. A method for configuring a UE for communication performed by circuitry of an evolved Node B (eNB) may include broadcasting, from the eNB, a physical downlink control channel (PDCCH) transmission on a licensed band, transmitting, from the eNB to the UE, a physical broadcast channel (PBCH) transmission multiplexed with a machine-type communication (MTC) PBCH (M-PBCH) transmission, the M-PBCH transmission including a MTC master information block (M-MIB) in a MTC region of the licensed band, wherein the MTC region includes a subset of frequencies of the licensed band, and transmitting, from the eNB to the UE, a first data transmission on the MTC region in a downlink.

Abstract: Embodiments described herein relate generally to a communication between a user equipment (UE) and an evolved Node B (eNB). The UE and eNB may perform enhanced physical downlink control channel (EPDCCH)-less operation for scheduling of one or more common control messages, such as one or more system information blocks (SIBs), a random access response (RAR) message, or a paging message. Additionally, or alternatively, an eNB may configure a subset of aggregation levels for the search space of the UE to use for receiving a physical downlink control channel (PDCCH) or enhanced PDCCH (EPDCCH). Other embodiments may be described and/or claimed.

Abstract: A machine type communication (MTC) device is configured to communicate through a long term evolution (LTE) network. The MTC device include a wireless transceiver to receive a signal through the LTE network, a soft buffer configured to store a plurality of soft channel bits for up to a maximum number of hybrid automatic retransmission request (HARQ) processes, and a signal processing unit. The signal processing unit is configured to determine a total number of soft channel bits based at least on the maximum number of HARQ processes, and to use limited buffer rate matching (LBRM) to store a reduced number of the total number of soft channel bits in the soft buffer.
