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: 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: Embodiments of an Evolved Node-B (eNB), User Equipment (UE), and methods for flexible duplex communication are generally described herein. The eNB may transmit a downlink control information (DCI) block to the UE during a group of time-division duplex (TDD) sub-frames. The eNB may further receive an uplink control information (UCI) block from the UE during the group of TDD sub-frames. A first candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and an uplink control portion. A second candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and may exclude uplink control portions.

Abstract: Techniques are described for compressing the PUCCH resources reserved for acknowledging downlink data transmissions when those resources are implicitly signaled by EPDCCHs that schedule the downlink transmissions in TDD mode. An acknowledgement resource offset field transmitted in the EPDCCH is configured to correspond to one or more values that compress the region in PUCCH resource index space that would otherwise be reserved for the subframes of a bundling window.

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: In one example, an apparatus of an e-NodeB (eNB) capable to establish a communication connection with a user equipment (UE) in a communication network, the eNB comprising processing circuitry to transmit a downlink (DL) beamforming training reference signal (BF-TRS) to a user equipment (UE) using transmit beamforming weights that are the same. Other examples are also disclosed and claimed.

Abstract: Techniques for contention window size (CWS) adaptation (CWSA) are discussed. One example apparatus can comprise a processor that can receive HARQ messages UEs in response to PDSCH transmissions in one or more reference subframes. The HARQ messages can comprise HARQ-ACK values that denote a HARQ-ACK state for a transport block associated with License Assisted Access (LAA) operation, wherein each of the HARQ-ACK states is one of a DTX state, an ACK state, a NACK state, or an “any” state. The processor can also; determine a metric value for each of the HARQ-ACK states; calculate a CWS adjustment metric based on the determined metric values; increase a CWS to a next higher allowed value when the CWS adjustment metric is greater than or equal to a threshold; and reset the CWS to a minimum allowed value when the CWS adjustment metric is less than the threshold.

Abstract: Described are mechanisms for eNB support of DRS in LAA, in which DRS is transmitted at one or more DRS occasions within a DMTC window, subject to LBT. In some embodiments, an eNB may include hardware processing circuitry comprising an antenna port, a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine a DMTC window of a wireless communication channel. The second circuitry may be operable to initiate one or more CCA checks through an antenna coupled to the antenna port prior to a DRS occasion within a DMTC time window. The third circuitry may be operable to initiate a DRS transmission through the antenna within the DMTC window upon a CCA check of the set of one or more CCA checks sensing that the wireless communication channel is idle. Also described are mechanisms for proactive support of DRS in LAA.
