    Abstract: Methods, systems, and devices are described for generating a hybrid waveform for data transmission between a transmitting device and a receiving device. The transmitting device may employ an OFDM processing technique to periodically transmit known first pilot symbols mapped from a signal constellation where each signal has equal energy during a first time period and a cyclic prefix based single-carrier (CP-SC) processing technique to transmit data packets and second known pilot symbols during a second time period. Channel estimation is based on first pilot symbols, which are inserted into all subcarriers of OFDM symbol blocks within a specific period. Channel estimation tracking is based on the second pilot symbols interleaved within data packets. The receiving device may be configured to estimate CSI based in part on first pilot symbols and to track the channel estimation based in part on the second pilot symbols in order to provide reliable data detection.

    Abstract: Transmit power is controlled for a first uplink data transmission on Physical Uplink Shared Channel (PUSCH) during random access channel (RACH) procedure. Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power “steps” that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges. Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.

    Abstract: Systems and methodologies are described that facilitate assigning resources for an anchor carrier and an additional carrier with a grant message. The grant message communicated with an anchor carrier can include resource information a plurality of carriers. Moreover, the systems and methodologies that facilitate identifying control information for an anchor carrier and/or an additional carrier based upon an operating mode, wherein the operating mode is a legacy mode or an extended mode. Based on the operating mode, particular resources associated with control regions are monitored for control information for respective anchor carrier(s) or additional carrier(s).

    Abstract: Aspects describe utilizing a dedicated reference signal for supporting Network MIMO, distributed MIMO, Coordinated MultiPoint, and the like. A data modulation symbol is transmitting in the same direction as a pilot modulation symbol is transmitted. Two or more wireless devices can coordinate communications such that transmission of the same pilot modulation symbol and the same data modulation symbol are transmitted to a device in different directions, each direction associated with a wireless device and intended for a particular mobile device. Cluster-specific scrambling and/or user-group specific scrambling can be employed and a scrambling code can be communicated prior to transmission of the pilot modulation symbols and data modulation symbols.

    Abstract: A network device includes a plurality of physical-media entities (PMEs), each corresponding to a distinct channel, to generate transmit signals based on transmit packets received over a media-independent interface. The network device also includes a channel-bonding sublayer to direct the transmit packets from the media-independent interface to respective PMEs of the plurality of PMEs. The channel-bonding sublayer has a substantially fixed delay between the media-independent interface and the plurality of PMEs for the transmit packets.
