Abstract: Methods and apparatus are described for transmitting uplink control information (UCI) over an OFDMA-based uplink. In some embodiments, UCI symbols are mapped to resource elements (REs) in the time/frequency resource grid to maximize frequency diversity. In some embodiments, UCI is mapped in a manner that takes into account channel estimation performance by mapping UCI symbols to those REs that are closest (in terms of OFDM subcarriers/symbols) to REs that carry reference signals.

Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with an Evolved Node-B (eNB) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process a configuration transmission carrying a half-tone shifting indicator. The second circuitry may be operable to select one or more subcarrier frequencies for Uplink (UL) transmission based on the half-tone shifting indicator. The third circuitry may be operable to generate a UL transmission for the one or more subcarrier frequencies. The half-tone shifting indicator may have a first value indicating application of a half-subcarrier offset, and a second value indicating no application of the half-subcarrier offset.

Abstract: Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an apparatus for a base station is provided that includes a radio interface and a processor coupled to the radio interface. The processor is configured to receive a channel quality indicator (CQI) index, wherein the CQI index is based on a channel state information (CSI) reference resource, further wherein a first three orthogonal frequency-division multiplexing (OFDM) symbols of the CSI reference resource are occupied by control signals, select a modulation and coding scheme (MCS) for a physical downlink shared channel (PDSCH) based on the CQI index, and cause transmission of the PDSCH based on the selected MCS via the radio interface. Other embodiments are described and claimed.

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: In one example, a method for a user equipment (UE) includes generating uplink (UL) signal data. The UL signal data includes UL control information (UCI) and UL shared channel (UL-SCH), the UCI includes a hybrid automatic repeat request acknowledge (HARQ-ACK) feedback or a channel state information (CSI) report, and the CSI report includes a first CSI part and a second CSI part. One or more resource regions are allocated to transmission of the HARQ-ACK feedback or the first CSI part and the second CSI part. When frequency hopping is enabled for a transmission of PUSCH, the allocated one or more resource regions for the transmission of the HARQ-ACK feedback or the first CSI part and the second CSI part are substantially equally divided into two portions, and each portion is transmitted in each frequency hop, frequency first mapping is applied to the transmission of PUSCH in each frequency hop.

Abstract: Technology for a user equipment (UE) to perform reduced transmission time interval (TTI) data transmission within a wireless communication network is disclosed. The UE can process a process, for transmission to an eNodeB, control information within a short transmission time interval (TTI) over a short TTI resource block (RB) set within a short physical uplink control channel (S-PUCCH), wherein the short TTI is shorter in time than a TTI that has a duration of at least one (1) millisecond, and wherein the S-PUCCH is a subset of resources available for a short physical uplink shared channel (S-PUSCH) and the S-PUSCH is a subset of resources available for a legacy PUSCH transmission; and process, for transmission to the eNodeB, data within the short TTI over the short TTI RB set within the S-PUSCH.

Abstract: Systems and methods of reducing power consumption associated with paging or cDRX mode are described. A wake-up receiver (WUR) wakes up from an idle mode or cDRX state. Whether a wake-up signal (WUS) has been received by the WUR is determined. The WUS is a low-complexity signal that is less complicated than a PDCCH or PDSCH and is repeated multiple times at resource elements as indicated in a configuration from an eNB. If received, a baseband transceiver wakes up for reception of a PDCCH for the UE in a PO when the UE is in the idle mode or a PDSCH for the UE when the UE is in the cDRX state.

Abstract: An apparatus can receive or transmit parameters for a sounding reference signal (SRS) transmission configuration as an uplink (UL)/downlink (DL) configuration of a serving cell. A time division duplex (TDD) operation with a plurality of component carriers (CCs) can be enabled/generated based on the parameters and at least one component carriers being reserved for the UL transmission or having a higher priority than a physical channel transmission such as a physical uplink shared channel (PUSCH) transmission or a physical uplink control channel (PUCCH) transmission.
