he resulting size of bitmap in that case equals to [66]. The Type-II CSI was designed to enhance the performance of MU-MIMO transmission. The accuracy of spatial channel feedback in case of Type-II CSI allows interference sup- pression improvement through use of advanced precoding schemes such MMSE precoding. An accurate knowledge of the channel increases suppression capabilities of intra-cell inter- ference. The beamforming vector in Type-II codebook is represented as linear combination of 2, 3, or 4 DFT beams as Vki, where P(WB) Prli denotes the wideband beam amplitude scaling factor; Prli (SB) is the subband beam amplitude scaling factor, and Crli is the beam combining coefficient (phase) for beam i, polarization r, and layer l [66]. New Radio Access Physical Layer Aspects (Part 2) 643 For non-codebook-based uplink transmission, PUSCH transmission can be scheduled by DCI format 0_0, DCI format 0_1 or semi-statically configured. The UE can determine its PUSCH precoder and transmission rank based on the SRI when multiple SRS resources are configured, where the SRI is given by the SRI in DCI or the SRI is given by RRC parame- ter srs-ResourceIndicator. The UE must use one or multiple SRS resources for SRS trans- mission. In an SRS resource set, the maximum number of SRS resources which can be configured for the UE for simultaneous transmission on the same symbol and the maximum number of SRS resources depend on the UE capability. It must be noted that only one SRS port for each SRS resource can be configured and only one SRS resource set can be config- ured with higher layer parameter usage in SRS-ResourceSet set to "nonCodebook". The maximum number of SRS resources that can be configured for non-codebook-based uplink transmission is 4. The indicated SRI in the nth slot is associated with the most recent trans- mission of SRS resource(s) identified by the SRI, where the SRS transmission is prior to the PDCCH carrying the SRI [9]. For non-codebook-based uplink transmission, the UE can calculate the precoder used f
