Time-division duplex frame structure for narrowband communications

Abstract:

A UE may determine a frame structure for narrowband communications, the frame structure corresponding to one frame structure from a group of TDD frame structures of different downlink and uplink subframe configurations. The UE receives configuration information indicating a first carrier to monitor for a BCH and/or a SIB1. Then, the UE receives a PSS, an SSS, and the BCH and/or the SIB1 using the frame structure determined for the narrowband communications. The first carrier that is used to receive the BCH and/or the SIB1 may be different from a second carrier used to receive one or more of the PSS or the SSS.
