Abstract

One disclosure of the present application provides a method for a narrowband (NB) wireless device to determine whether or not to transmit a scheduling request (SR). The method may comprise a step of determining whether or not to transmit an SR by using a resource for the transmission of a hybrid automatic retransmit request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) signal. The step of determination may be performed if one or more HARQ processes are run. The resource for the HARQ ACK/NACK signal may include a narrowband physical uplink shared channel (NPUSCH).

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for transmitting a signal for a narrowband physical uplink shared channel (NPUSCH), the method performed by a wireless device and comprising:
 applying a code to the signal for the NPUSCH; and   transmitting the signal for the NPUSCH in which the code is applied,   wherein the code is determined based on whether a scheduling request (SR) is to be transmitted through the signal for the NPUSCH.   
     
     
         2 . The method of  claim 1 , wherein the signal for the NPUSCH includes hybrid automatic repeat and request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) information. 
     
     
         3 . The method of  claim 1 , wherein the signal for the NPUSCH is generated based on a NPUSCH format 2. 
     
     
         4 . The method of  claim 1 , wherein the code is determined among a first code and a second code based on whether an SR is to be transmitted. 
     
     
         5 . The method of  claim 4 , wherein the first code includes a positive value and the second code includes a negative value. 
     
     
         6 . The method of  claim 4 , wherein
 the first code includes at least values of 1, −1, 1 and −1, based on that the SR is to be transmitted through the signal for the NPUSCH.   
     
     
         7 . The method of  claim 4 , wherein
 the first code includes at least one negative 1, based on that the SR is to be transmitted through the signal for the NPUSCH, and   the second code includes a positive  1 , based on that the SR is not to be transmitted.   
     
     
         8 . The method of  claim 4 , wherein the first code is orthogonal with the second code. 
     
     
         9 . A wireless device for transmitting a signal for a narrowband physical uplink shared channel (NPUSCH), the wireless device comprising:
 a transceiver; and   a processor which applies a code to the signal for the NPUSCH and controls the transceiver to transmit the signal for the NPUSCH in which the code is applied,   wherein the code is determined based on whether a scheduling request (SR) is to be transmitted through the signal for the NPUSCH.   
     
     
         10 . The wireless device of  claim 9 , wherein the signal for the NPUSCH includes hybrid automatic repeat and request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) information. 
     
     
         11 . The wireless device of  claim 9 , wherein the signal for the NPUSCH is generated based on a NPUSCH format 2. 
     
     
         12 . The wireless device of  claim 9 , wherein the code is determined among a first code and a second code based on whether an SR is to be transmitted through the signal for the NPUSCH. 
     
     
         13 . The wireless device of  claim 12 , wherein the first code includes a positive value and the second code includes a negative value. 
     
     
         14 . The wireless device of  claim 12 , wherein
 the first code includes at least values of 1, −1, 1 and −1, based on that the SR is to be transmitted through the signal for the NPUSCH.   
     
     
         15 . The wireless device of  claim 12 , wherein
 the first code includes at least one negative 1, based on that the SR is to be transmitted through the signal for the NPUSCH, and   the second code includes a positive  1 , based on that the SR is not to be transmitted.   
     
     
         16 . The wireless device of  claim 12 , wherein the first code is orthogonal with the second code. 
     
     
         17 . A base station cell for receiving a signal for a narrowband physical uplink shared channel (NPUSCH), the base station comprising:
 a transceiver; and   a processor which controls the transceiver to receives the signal for the NPUSCH,   wherein the signal for the NPUSCH includes a code, which is determined based on whether a scheduling request (SR) is to be transmitted through the signal for the NPUSCH.   
     
     
         18 . The base station of  claim 17 , wherein the signal for the NPUSCH includes hybrid automatic repeat and request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) information. 
     
     
         19 . The base station of  claim 17 , wherein the signal for the NPUSCH is generated based on a NPUSCH format 2. 
     
     
         20 . The base station of  claim 17 , wherein the code includes
 a first code including at least values of 1, −1, 1 and −1, based on that the SR is to be transmitted through the signal for the NPUSCH.
