Abstract: Certain aspects of the present disclosure provide techniques for hopping design for larger bandwidth allocations in enhanced machine type communications (eMTC). A method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving a resource allocation for uplink transmission in at least one subframe. The resource allocation includes a set of allocated subframes and configuration information for frequency hopping. The method includes determining allocated frequency hopped resources, within a system bandwidth, for each subframe of the set of allocated subframes. The method includes including a center resource block (RB) in addition to the determined allocated frequency hopped resources if the determined allocated frequency hopped resources include resources around the center RB. The method includes removing a last RB from the determined allocated frequency hopped resources if the determined allocated frequency hopped resources include resources around the center RB.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a scrambling sequence vector pair associated with a scrambling sequence matrix with a high level of frequency domain orthogonalization is determined. A spreading sequence vector pair associated with a spreading sequence matrix with a low level of time domain orthogonalization is determined. An orthogonal cover code (OCC) matrix is generated by assigning the determined scrambling sequence vector pair to the determined spreading sequence vector pair. The OCC may be applied to one or more demodulation reference signals associated with a set of resource blocks for transmission.
