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: A closed loop MIMO feedback system is described in which the number of available antenna ports is less than the number of antenna elements. In one implementation, sounding reference signals, received from a number of UEs, may be used, by a base station, to generate and transmit a number of OFDMA Channel State Information Reference Signals (CSI-RSs). The OFDMA CSI-RSs may be determined based on the top eigen beams associated with an average channel covariance matrix determined based on the received sounding reference signals. A UE, in response to receiving the OFDMA CSI-RSs, may determine a preferred eigen beam and transmit a quantized version of the preferred eigen beam back to the eNB. Subsequent communications with the UE may be made using beamforming techniques that are based on the quantized version of the preferred eigen beam.

Abstract: In embodiments, apparatuses, methods, and storage media may be described for reducing the overhead associated with the transmission of channel training signals from an eNodeB (eNB) of a wireless network. Specifically, the eNB may receive feedback from a user equipment (UE) regarding the received signal energy of a first and second beamformed signal produced with a first and second beamforming vector, respectively. The eNB may identify, based on the feedback of the received signal energy, a signal subspace and a null subspace. The eNB may then transmit a channel training signal to the signal subspace.

Abstract: This disclosure describes systems, methods, computer readable media, and/or apparatus related to encoding wireless communication preamble structures with cyclic redundancy check (CRC) that is performed on both a common part, as well as, station specific parts of a signaling field. The signaling field generated by this mechanism may be relatively shorter, resulting in less preamble overhead, than if a separate CRC was to be provided for each of the station specific parts, as well as the common part of the signaling field. In additional embodiments, tail bits may be provided for a combination of the common part of the signaling field and each station specific part of the signaling field. Compared to providing tail bits separately for the common part and each of the station specific parts, removing the tail bits from the tail bits form the common part may result in relatively less overhead of the preamble structure.
