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.

According UE is configured to receive a channel state information reference signal (CSI-RS) from an evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB), determine channel state information based on the CSI-RS, and send the channel state information to the eNB. The channel state information includes a precoding matrix indicator corresponding to a first precoding matrix. The UE is also configured to receive a UE specific reference (UE-RS) signal and a physical downlink shared channel (PDSCH) signal. The UE-RS is precoded with a second precoding matrix. The UE estimates a UE-RS effective channel including the second precoding matrix based on the UE-RS and decodes data from the PDSCH signal based on an the first precoding matrix and the UE-RS effective channel.

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:
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.
