Abstract: A network controller may configure one or more channel state information-reference signal (CSI-RS) configurations for transmitting RSs to user equipments (UEs) for tracking. A CSI-RS configuration may specify a set of CSI-RS resources for transmitting RSs in two consecutive slots. The set of CSI-RS resources may include a plurality of one-port CSI-RS resources configured according to the CSI-RS configuration. The CSI-RS configuration may specify a quasi co-location (QCL) configuration including a set of QCL parameters, where a demodulation reference signal (DMRS) has a QCL relationship with the RS with respect to the set of QCL parameters. The network controller may signal the one or more CSI-RS configurations to UEs.

Abstract: A method for receiving wideband (WB) LTE uplink signals. A base station may signal a first frequency tone assignment to a first user equipment (UE), the first frequency tone assignment scheduling at least a first set of subcarriers allocated to the first UE, subcarriers in the first set of subcarriers being non-contiguous in the frequency domain. Subcarriers in the first set of subcarriers may be interleaved with subcarriers in a second set of subcarriers. The first UE may perform a first single carrier frequency division multiple access (SC-FDMA) uplink transmission over the first set of subcarriers. A second UE may perform a second SC-FDMA uplink transmission, the second SC-FDMA uplink transmission spanning the second set of subcarriers.

Abstract: Methods for wireless communications over a wideband carrier are provided. Time-frequency resources of the wideband carrier within a transmission time interval are divided into multiple time-frequency resource blocks. Each of the time-frequency resource blocks corresponds to a group of contiguous subcarriers of the wideband carrier and orthogonal frequency division multiplexing symbols. Data streams may be scheduled to be transmitted in different time-frequency resource blocks, and may be destined for different user equipments or the same user equipment. Baseband processing operations may be performed on data streams scheduled in different time-frequency resource blocks independently from one another. Separate control channels or one common control channel may be configured for data transmissions in different time-frequency resource blocks.
