Abstract:
An apparatus and method for CSI reporting in the unlicensed band are described. CRS-RSs are transmitted from a RAN in narrowband data channels in the unlicensed band to an eMTC UE. The UE determines the CQI and PMI from the CRS-RSs and transmits a periodic CSI report to the RAN that contains the CQI and PMI. The periodic CSI report is received at a nsfrel th subframe of a nmframeth mframe, where nmframe satisfies nmframe mod Npd,mframe=NOFFSET,mframe where Nmframe is a reporting period in terms of mframes and NOFFSET,mframe is a reporting period offset in terms of mframes, and nsfrel satisfies nsfrel−20=NOFFSET,CQI where NOFFSET,CQI is a reporting period offset in subframes.
