Title:
METHODS AND APPARATUS FOR DECODING DL PHY CHANNELS IN A NARROW BAND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/054771
Kind Code:
A1
Abstract:
Apparatus and methods are provided for decoding DL PHY channels in a narrow band wireless system. In one novel aspect, the UE performs a cell search and determines a first location of a resource block carrying system signals, obtains a second location of a second resource block based on the first resource block, wherein the second resource block includes a format indicator, determines a DL transmission format based on the format indicator, and receives and decodes a first DL physical channel based on the DL transmission format. In one embodiment, the UE operates in either a standalone mode, an in-band mode, or a guard-band mode. The DL transmission format comprises an offset index from a middle/central frequency of the first resource block in the in-band mode or the guard-band mode. In another embodiment, the UE further decodes a second DL physical channel carrying the format indicator.
