摘要： Embodiments of a system and method for beamforming in a Wireless Network are generally described herein. In some embodiments, an enhanced Node B (eNB) transmits to User Equipment (UE), from a plurality (Nc) of antenna ports of a plurality (Nt) of transmit antennas, a data signal where signal power is allocated in eigen beams, each of the Nt transmit antennas having antenna ports that are adjustable in elevation and in azimuth. The eNB also determines and transmits to the UE a Pc set of the largest principal eigen beams of the data signal and receives, as feedback from the UE, a precoding matrix that identifies the antenna port from which strongest energy in the data signal is detected at the UE. The eNB uses the precoding matrix for beamforming.

摘要： Embodiments pertain to systems, methods, and component devices for dynamic non-orthogonal multiple access (NOMA) communications. A first example embodiment includes user equipment (UE) configured to receive a first downlink control indicator (DCI) from an evolved node B (eNB) and process the first subframe as a first higher power NOMA subframe in response to a first power ratio signal. The DCI includes the first power ratio signal for a first NOMA subframe. The UE may then receive, from the eNB, a second DCI, the second DCI comprising a second power ratio signal for a second subframe and process, by the UE, the second subframe as a second lower power NOMA subframe in response to the second power ratio signal. Additional embodiments may further use another DCI with a third power ratio signal to configure the UE to receive orthogonal multiple access (OMA) communications.

摘要： Embodiments allow an eNBs and a target UE to both calculate which resource block groups (RBGs) to use to transmit data. Because the RBGs that will contain information of interest can be pre-calculated, there is no need to receive and store all RBGs in the transmitted signal before decoding the signal and identifying which RBGs are of interest to the recipient. This allows receivers to buffer and/or store only those RBGs that will contain received information and discard others. The amount of information that needs to be stored and/or buffered thus is less and can result in receivers with less memory and, hence, lower cost. In order to calculate which RBGs are to be used to transmit and/or receive information, a logical RBG index is first calculated and the logical RBG index is mapped to a physical RBG index.
摘要翻译：实施例允许eNB和目标UE两者都计算用于发送数据的哪些资源块组（RBG）。因为可以预先计算将包含感兴趣的信息的RBG，所以在解码信号之前不需要在发送的信号中接收和存储所有RBG，并且识别接收者感兴趣的RBG。这允许接收器缓冲和/或仅存储将包含接收到的信息并丢弃其他的RBG。因此，需要存储和/或缓冲的信息量较少，并且可能导致接收机具有较少的存储器，并因此导致较低的成本。为了计算哪些RBG用于发送和/或接收信息，首先计算逻辑RBG索引，并将逻辑RBG索引映射到物理RBG索引。

摘要： Embodiments herein relate to wireless communication using combined channel training and physical layer header (SIG) signaling. Devices that comply with the 802.11ax or High Efficiency WLAN (HEW) standard may generate and transmit packets that include such combined information. The combined information may be beamformed to a receiver device via an OFDM signal, which may be decoded by the receiver device to obtain subsequent data included in the signal. For example, initial training symbols associated with channel training subcarriers in the signal may be detected and used to perform a rough estimate of the channel. The rough estimate may thereafter be refined using data symbols detected from adjacent data subcarriers using the channel training symbols. In this way, data subcarriers may also be used to determine a channel response along with channel training subcarriers. Channel training information may be transmitted with data, such as user-specific information, in a single symbol.
