Method and apparatus for signal configuration in a wireless communication system

Abstract

Embodiments of the present disclosure provide methods, apparatuses and computer program for signal configuration in a wireless communication system. A method implemented at a network device comprises: transmitting information related to a resource allocation for a signal, and broadcasting the signal in accordance with the resource allocation; wherein the signal includes at least one of: a reference signal and a control signal containing system information. By virtue of the method, resource utilization may be more flexibly controlled.

What is claimed is: 
     
         1 . A method performed by a base station, the method comprising:
 transmitting to a user equipment (UE), in a broadcast channel, first information indicating a subcarrier spacing for a System Information Block (SIB); and   transmitting the SIB to the UE,   wherein a value of the subcarrier spacing is dependent on a frequency band region where the broadcast channel is transmitted.   
     
     
         2 . The method of  claim 1 , wherein a system bandwidth of the base station is divided into a plurality of frequency band regions, and the frequency band region where the broadcast channel is transmitted is one of the plurality of frequency band regions. 
     
     
         3 . The method of  claim 1 , further comprising:
 transmitting, in the broadcast channel, second information indicating a number of resource blocks for a control signal related to the SIB.   
     
     
         4 . The method of  claim 3 , wherein the second information indicates a transmission opportunity in time domain for the control signal related to the SIB. 
     
     
         5 . The method of  claim 3 , further comprising:
 transmitting a synchronization signal sequence for the second information.   
     
     
         6 . The method of  claim 5 , wherein said transmitting the synchronization signal sequence comprises:
 transmitting the synchronization signal sequence with an associated indication of the broadcast channel, the associated indication comprising an index.   
     
     
         7 . A method performed by a user equipment (UE), the method comprising:
 receiving from a base station, in a broadcast channel, first information indicating a subcarrier spacing for a System Information Block (SIB); and   receiving the SIB from the base station,   wherein a value of the subcarrier spacing is dependent on a frequency band region where the broadcast channel is received.   
     
     
         8 . The method of  claim 7 , wherein a system bandwidth of the base station is divided into a plurality of frequency band regions, and the frequency band region where the broadcast channel is received is one of the plurality of frequency band regions. 
     
     
         9 . The method of  claim 7 , further comprising:
 receiving, in the broadcast channel, second information indicating a number of resource blocks for a control signal related to the SIB.   
     
     
         10 . The method of  claim 9 , wherein the second information indicates a transmission opportunity in time domain for the control signal related to the SIB. 
     
     
         11 . The method of  claim 9 , further comprising:
 receiving a synchronization signal sequence for the second information.   
     
     
         12 . The method of  claim 11 , wherein said receiving the synchronization signal sequence comprises:
 receiving the synchronization signal sequence with an associated indication of the broadcast channel, the associated indication comprising an index.   
     
     
         13 . A base station comprising:
 a transceiver; and   a processor configured to control the transceiver to:
 transmit to a user equipment (UE), in a broadcast channel, first information indicating a subcarrier spacing for a System Information Block (SIB); and 
 transmit the SIB to the UE, 
   wherein a value of the subcarrier spacing is dependent on a frequency band region where the broadcast channel is transmitted.   
     
     
         14 . The base station of  claim 13 , wherein a system bandwidth of the base station is divided into a plurality of frequency band regions, and the frequency band region where the broadcast channel is transmitted is one of the plurality of frequency band regions. 
     
     
         15 . The base station of  claim 13 , wherein the processor is further configured to control the transceiver to:
 transmit, in the broadcast channel, second information indicating a number of resource blocks for a control signal related to the SIB.   
     
     
         16 . The base station of  claim 15 , wherein the second information indicates a transmission opportunity in time domain for the control signal related to the SIB. 
     
     
         17 . The base station of  claim 15 , wherein the processor is further configured to:
 transmit a synchronization signal sequence for the second information.   
     
     
         18 . The base station of  claim 17 , wherein said transmit of the synchronization signal sequence comprises:
 transmitting the synchronization signal sequence with an associated indication of the broadcast channel, the associated indication comprising an index.
