    摘要: Techniques are described for wireless communications at a user equipment (UE). One method includes determining a first cell identifier (ID) associated with a first downlink transmission in a first radio frequency spectrum band of paired radio frequency spectrum bands, determining a second cell ID associated with a second downlink transmission in a second radio frequency spectrum band of the paired radio frequency spectrum bands, and communicating based on the first cell ID and the second cell ID. In some cases, the method may include determining a cell ID associated with a downlink transmission in an uplink radio frequency spectrum band, and receiving the downlink transmission in a subframe of the uplink radio frequency spectrum band. The downlink transmission may be based on the cell ID and a format of a physical uplink shared channel (PUSCH), and may include an eight layer single-user multiple-input multiple-output (SU-MIMO) transmission.

    摘要: Certain aspects of the present disclosure provide techniques for adaptive modulo base selection for non-linear precoding. Aspects provide a method for wireless communications that can be performed by a base station (BS). The BS adaptively selects a modulo base for a data stream for at least one user equipment (UE) in a transmission to one or more UEs. The BS selects the modulo base based on one or more parameters. The BS transmits a signal for at least one UE of the one or more UEs to identify the selected modulo base. The BS performs the transmission to the one or more UEs. The UE receives the transmission from the BS and the signal for the identification of the selected modulo base. Based on the signal, the UE determines the modulo base for at least one data stream in the transmission and decodes the data stream using the modulo base.

    摘要: Enhanced channel state information (CSI) procedures for full dimension-multiple input, multiple output (FD-MIMO) is discussed in which a number of CSI reference signal (CSI-RS) ports configured for a user equipment (UE) is determined. In response to the CSI-RS ports including both horizontal and vertical ports, the UE may determine a first precoding matrix from a plurality of precoding matrices constructed by a Kronecker product of a horizontal precoding matrix and a vertical precoding matrix. The UE selects a predetermined number of precoding vectors out of the first precoding matrix and generates a wideband precoding matrix, based on the selected predetermined number of precoding vectors. The UE reports one or more CSI reports, wherein the CSI reports includes at least one precoding matrix indicator (PMI) for the first precoding matrix and at least an indication of the selection of the predetermined number of precoding vectors.
