Abstract: Future LTE systems will support massive carrier aggregation that necessitates transmission of a large number of acknowledgement signals (HARQ-ACKs) in response to downlink data transmitted over multiple component carriers. Described herein are methods and apparatus for efficiently transmitting HARQ-ACK and periodic channel state information (P-CSI) bits over the PUCCH (physical uplink control channel).

Abstract: Examples may include techniques for a identifying physical hybrid automatic request (HARQ) indicator channel (PHICH) resources. A PHICH resource along with one or more additional PHICH may be identified for use to enhance coverage for user equipment to receive positive acknowledgements (ACKs) or negative acknowledgement (NAKs) from an evolved Node B (eNB). An ACK/NAK may be sent to the UE by the eNB responsive to receiving data over a physical uplink shared channel (PUSCH) established with the UE. Both the UE and the eNB may operate in compliance with one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards.

Abstract: Embodiments of a User Equipment (UE) to operate in accordance with a physical random access channel (PRACH) are disclosed herein. The UE may comprise hardware processing circuitry to determine a coverage enhancement category for the UE based on downlink channel statistics related to reception of downlink signals at the UE from an Evolved Node-B (eNB) and an uplink-downlink imbalance parameter related to uplink reception at the eNB. The hardware processing circuitry may be further to select, for use in a coverage enhancement mode, a PRACH preamble from a set of candidate PRACH preambles based on the determined coverage enhancement category for the UE. In some embodiments, at least some of the candidate PRACH preambles may span a different number of sub-frames.

Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB), and methods for communication of uplink messages are generally described herein. The UE may receive, from an eNB, one or more downlink control messages that may indicate an allocation of PUCCH channel resources. The UE may transmit an uplink control message in at least a portion of the allocated PUCCH channel resources. When the PUCCH channel resources are allocated according to an edge configuration, the PUCCH channel resources may be restricted to a lower edge portion and an upper edge portion of the network channel resources. When the PUCCH channel resources are allocated according to a distributed configuration, the PUCCH channel resources may include one or more middle portions of the network channel resources. The middle portions may be exclusive to the lower edge and upper edge portions.

Abstract: Technology for decreasing latency for contention based scheduling request (SR) is disclosed. A user equipment (UE) can randomly select a physical random access channel (PRACH) preamble index for a PRACH transmission. The UE can multiplex the PRACH preamble index together with a SR message containing a cell radio network temporary identifier (C-RNTI) and a buffer status report (BSR) for the PRACH transmission. The UE can process, for transmission, to an enhanced node B (eNB), the PRACH preamble index multiplexed with the SR message in a subframe #(n) of the PRACH transmission, wherein n is a subframe number.

Abstract: Embodiments of user equipment (UE), an enhanced node B (eNB), and methods of signaling for proximity services and device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, the UE receives configuration information for a D2D discovery resource pool of a cell. The configuration information includes an indication that the D2D discovery resource pool has been logically divided into a plurality of sub-discovery resource pools. The UE performs an initial transmission of a discovery signal in a discovery period using a single D2D discovery resource from a first sub-discovery resource pool of the plurality of sub-discovery resource pools. The UE performs a number of additional transmissions of the discovery signal in the discovery period using additional D2D discovery resources from sub-discovery resource pools of the plurality of sub-discovery resource pools other than the first sub-discovery resource pool. Other apparatuses and methods are also described.

Abstract: An eNodeB (eNB), user equipment (UE) and method of providing a flexible Radio Access Technology (FRAT) are generally described. The information (resource allocation, partition information and numerology) of at least one of a plurality of RATs used by the eNB is provided to a UE. Each RAT has a flexible subcarrier spacing and symbol duration, which are integer multiples of a base subcarrier spacing and symbol duration, and is associated with at least one of different temporal and frequency resources. The symbol and/or frame structure of each RAT are independent. A Transmission Time Interval (TTI) boundary between the RATs is common, and the RATs comprise a common reference TTI duration. The information of the RATs is provided either via a different RAT than the RAT used by the UE for communication or via a dedicated carrier in the RAT used by the UE for communication.

Abstract: Embodiments of an enhanced node B (eNB), user equipment (UE) and methods of signaling for proximity services and device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, the eNB may transmit signaling to indicate D2D discovery zone configuration to proximity service (ProSe) enabled UEs. The signaling may indicate time and frequency resources and a periodicity of a discovery zone and may indicate operational parameters for the discovery zone. The resources of the D2D discovery zone may be allocated for D2D discovery signal transmission by the ProSe-enabled UEs.
