Base station device, terminal device, and transmission method

Abstract

A base station device includes: a processor circuitry configured to generate first data, second data to be transmitted with a latency-critical communication and an indication signal; and a transmitter configured to transmit the first data, the second data and the indication signal to a terminal device, wherein the indication signal includes a plurality of bits which have a one-to-one mapping with a plurality of sub-areas in an area that is used for transmitting the first data, when the indication signal indicates one or more sub-areas are used for transmitting the second data, the transmitter performs no transmission for the first data using the corresponding one or more sub-areas, when the indication signal indicates the one or more sub-areas are used for transmitting the first data, the transmitter transmits the first data using the corresponding one or more sub-areas without transmitting the second data using the corresponding one or more sub-areas.

What is claimed is: 
     
         1 . A base station device comprising:
 a processor circuitry configured to generate first data, second data to be transmitted with a latency-critical communication and an indication signal; and   a transmitter configured to transmit the first data, the second data and the indication signal to a terminal device, wherein   the indication signal includes a plurality of bits which have a one-to-one mapping with a plurality of sub-areas in an area that is used for transmitting the first data,   when the indication signal indicates one or more sub-areas are used for transmitting the second data, the transmitter performs no transmission for the first data using the corresponding one or more sub-areas, and   when the indication signal indicates the one or more sub-areas are used for transmitting the first data, the transmitter transmits the first data using the corresponding one or more sub-areas without transmitting the second data using the corresponding one or more sub-areas.   
     
     
         2 . The base station device according to  claim 1 , wherein a type of the first data is different from that of the second data. 
     
     
         3 . The base station device according to  claim 1 , wherein the second data is URLLC data. 
     
     
         4 . The base station device according to  claim 1 , wherein the first data is eMBB data. 
     
     
         5 . A terminal device comprising:
 a receiver configured to receive, from a base station, a reception signal including first data or second data to be transmitted with a latency-critical communication and an indication signal including a plurality of bits which have a one-to-one mapping with a plurality of sub-areas in an area; and   a processor circuitry configured to determine, based on the indication signal, whether the second data is included in one or more sub-areas, wherein   the receiver receives the reception signal including the second data in the one or more sub-areas and the indication signal including the plurality of bits indicating that the corresponding one or more sub-areas are not used for transmitting the first data, when the indication signal indicates the one or more sub-areas are used for transmitting the second data,   receives the reception signal including the first data in the one or more sub-areas and the indication signal including the plurality of bits indicating that the corresponding one or more sub-areas are used for transmitting the first data, when the one or more sub-areas are used for transmitting the first data.   
     
     
         6 . The terminal device according to  claim 5 , wherein a type of the first data is different from that of the second data. 
     
     
         7 . The terminal device according to  claim 5 , wherein the second data is URLLC data. 
     
     
         8 . The terminal device according to  claim 5 , wherein the receiver demodulates the reception signal to obtain the first data by excluding the one or more sub-areas which are used for transmitting the second data after demodulating the indication signal.
