Abstract: Techniques, apparatus and methods are disclosed that enable reduced signaling overhead in a fifth generation (5G) wireless system. The system includes support for asynchronous uplink transmission, resource pool configuration, acknowledgement response and retransmission. For example, in a Type-1 transmission scheme, a user equipment (UE) selects one resource within the resource pool and transmits data in the uplink on the selected resource. In a Type-2 transmission scheme, a UE selects one resource within a scheduling request (SR) region in the resource pool, transmits the SR for the resource which contains the resource allocation for data transmission, and transmits the uplink data on the resource which is indicated in the SR information. In a Type-3 transmission scheme, a UE selects a resource within the SR region, transmits the SR on the selected resource with information on the resource selected for subsequent data transmission and transmits on the indicated resource if it receives an acknowledgment, in response to its transmitted SR.

Abstract: Systems, apparatus, user equipment (UE), evolved node B(eNB), and methods are described for machine-type communications (MTC) with early termination of repeated transmissions. In MTC implementations with narrow bandwidth, significant numbers of retransmissions may be scheduled based on channel quality measurements. If data is successfully decoded at a receiving device while a significant number of retransmissions remain, system resources are wasted. Embodiments described herein thus use downlink control messaging or intermediate hybrid automatic repeat request (HARQ) messaging for early termination of repeated messages.

Abstract: Methods, systems, devices, and apparatus including evolved node B (eNB) or user equipment (UE) for machine-type communications (MTC) with narrowband deployment are described. One embodiment includes control circuitry configured to determine a super-frame structure, where the super-frame structure is set, at least in part, on a bandwidth of the narrowband deployment, with a plurality of downlink physical channels areas multiplexed as part of a first downlink super-frame of the super-frame structure. Such an embodiment may include communication circuitry configured to transmit the first downlink super-frame comprising the plurality of multiplexed downlink physical channels, receive a plurality of uplink physical channels, and receive, in response to transmission of the first downlink super-frame, a hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK).

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: Examples may include techniques to enable user equipment (UE) to establish a device-to-device (D2D) communication link for D2D communications with another UE. In some examples, the D2D communications may occur when either both or at least one UE is within a coverage area for a wireless wide area network (WWAN). In some other examples, both UEs may be outside of the coverage area and may utilize a third UE to provide or relay information for use to establish the D2D communication link.

Abstract: A user equipment (UE) may communicate channel state information in a wireless network. The UE may include transceiver circuitry to receive orthogonal frequency division multiple access (OFDMA) signals from an Enhanced node B (eNB). The UE may include processing circuitry to derive one or more principal eigen beams from the received OFDMA signals. The principal eigen beams may have a rank greater than or equal to one. The processing circuitry may derive quantized eigen beams from the principal eigen beams. The processing circuitry may select, in response to the quantized eigen beams, a subset of available antenna ports on the eNB for receiving from the eNB and transmitting to the eNB. The UE may communicate to the eNB a bit pattern of the quantized eigen beams and at least one of a wideband channel quality indicator (CQI) or a subband CQI conditioned on the quantized eigen beams.

Abstract: Embodiments of a User Equipment (UE) and an Evolved Node-B (eNB) and methods for random access are generally described herein. As part of a random access procedure, the UE may transmit a physical random access channel (PRACH) preamble in a first portion of PRACH time and frequency resources and may receive a physical downlink shared channel (PDSCH) block that includes a random access response (RAR) to the PRACH preamble. The PDSCH block may be based on a random access radio network temporary identifier (RA-RNTI) associated with the first portion of the PRACH resources. Accordingly, the UE may use the RA-RNTI to determine that the PDSCH block is intended for the UE without usage of physical downlink control channel (PDCCH) blocks for the PDSCH block. In some embodiments, the UE may be configured for machine-type communication (MTC).
