Claim of US Patent No. 10,772,089

1. A user equipment (UE) comprising:receiving circuitry configured to receive indication information indicating whether a non-anchor physical resource block (PRB) is in in-band of an LTE carrier or in a guard band of the LTE carrier, and to receive, in a case that (a) an anchor PRB is in the guard band of the LTE carrier, and (b) the indication information indicates that the non-anchor PRB is in in-band of the LTE carrier, a non-anchor PRB configuration which indicates that the non-anchor PRB is in in-band of the LTE carrier and indicates a first offset from a middle PRB in a set of LTE in-band PRBs; and
determination circuitry configured to determine, based on the non-anchor PRB configuration, a location of the non-anchor PRB in the set of LTE in-band PRBs, wherein
the receiving circuitry is configured to receive an anchor PRB configuration, in a case that the anchor PRB is in in-band of the LTE carrier,
the anchor PRB configuration indicates that the anchor PRB is in in-band of the LTE carrier and indicates a second offset from the middle PRB in the set of LTE in-band PRBs,
the first offset is an integer number selected from a first range,
the second offset is an integer number selected from a second range different from the first range, and
the non-anchor PRB is different from the anchor PRB in that:
the non-anchor PRB is a PRB used by the UE for receiving a unicast transmission related to NarrowBand IOT (NB-IoT), but not used by the UE for receiving a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a master system information block (MIB), and a system information block (SIB), each of which is related to the NB-IoT; and
the anchor PRB is a PRB used by the UE for receiving the PSS, the SSS, the MIB, and/or the SIB.
