METHOD, BASE STATION, AND USER EQUIPMENT FOR INDICATING FREQUENCY POSITION OF WIRELESS SIGNAL
The present application provides a base station, including: a configuration unit, configured to configure any one or more of a carrier center frequency, a carrier frequency position, and a sub-band frequency position; and a transmission unit, configured to transmit a synchronization signal at a candidate frequency position and to transmit information configured by the configuration unit. The configuration unit performs configuration using any one or more of the following: master information block (MIB), a system information block (SIB), and dedicated radio resource control (RRC) signaling. The present application further provides user equipment (UE) and a corresponding method.
1 .- 36 . (canceled)
37 . A user equipment (UE) comprising:
receiving circuitry configured to receive a master information block (MIB) indicating an offset which represents a number of subcarriers between (a) a first subcarrier corresponding to a specific frequency position and (b) a second subcarrier corresponding to a frequency position of a synchronization signal; and
processing circuitry configured to determine the number of subcarriers on a basis of the MIB.
38 . The UE of claim 37 , wherein
the processing circuitry is further configured to determine a sub-band within a given carrier on a basis of (a) a starting PRB index and (b) a length of the sub-band in number of PRBs, wherein the starting PRB index is derived from a reference point in a frequency domain.
39 . The UE of claim 38 , wherein
the processing circuitry is further configured to receive an RRC signaling for determining the reference point.
40 . A base station comprising:
generating circuitry configured to generate a master information block (MIB) indicating an offset which represents a number of subcarriers between (a) a first subcarrier corresponding to a specific frequency position and (b) a second subcarrier corresponding to a frequency position of a synchronization signal; and
transmitting circuitry configured to transmit the MIB.
41 . The base station of claim 40 , wherein
the transmitting circuitry is further configured to transmitting an RRC signaling for determining a reference point in a frequency domain, wherein
the reference point is used to indicate a starting PRB index, and
a sub-band within a given carrier is indicated by (a) the starting PRB index and (b) a length of the sub-band in number of PRBs.
42 . A method performed by a user equipment (UE) comprising:
receiving a master information block (MIB) indicating an offset which represents a number of subcarriers between (a) a first subcarrier corresponding to a specific frequency position and (b) a second subcarrier corresponding to a frequency position of a synchronization signal; and
determining the number of subcarriers on a basis of the MIB.
43 . A method performed by a base station comprising:
generating a master information block (MIB) indicating an offset which represents a number of subcarriers between (a) a first subcarrier corresponding to a specific frequency position and (b) a second subcarrier corresponding to a frequency position of a synchronization signal; and
transmitting the MIB.
