Abstract

Embodiments of the disclosure provide a method and device for cross-numerology scheduling. The method comprises: determining at least one of a first time position associated with a first communication and a time interval between the first communication and a second communication, the first communication using a first numerology, the second communication using a second numerology and being performed in response to the first communication.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method performed by a user equipment, the method comprising:
 receiving from a base station, information indicating a number of slots k;   receiving from the base station a PDSCH (Physical Downlink Shared Channel); and   transmitting to the base station, HARQ-ACK (Hybrid Automatic Repeat Request) information corresponding to the PDSCH, in a PUCCH (Physical Uplink Control Channel) transmission,   wherein, if reception of the PDSCH is scheduled in a first slot of a first array of slots having a first subcarrier spacing, the PUCCH transmission is performed within a second slot of a second array of slots having a second subcarrier spacing,   wherein, if the number of slots k equals 0, the second slot corresponds to a last slot, of the second array of slots having the second subcarrier spacing, that overlaps with the reception of the PDSCH,   wherein, if the number of slots k is equal to or larger than 1, the second slot is positioned the number of slots k after the last slot, of the second array of slots having the second subcarrier spacing, that overlaps with the reception of the PDSCH,   wherein the first subcarrier spacing and the second subcarrier spacing are mutually different, and   wherein a number of slots per subframe depends on each value of the first subcarrier spacing and the second subcarrier spacing.   
     
     
         2 . The method of  claim 1 , wherein the first subcarrier spacing is larger than the second subcarrier spacing. 
     
     
         3 . The method of  claim 1 , wherein the second subcarrier spacing is larger than the first subcarrier spacing. 
     
     
         4 . The method of  claim 1 , wherein the information indicating the number of slots k is indicated by dynamic control information, if present, or provided by higher layer signaling. 
     
     
         5 . The method of  claim 1 , wherein the information indicating the number of slots k is provided by higher layer signaling. 
     
     
         6 . The method of  claim 1 , wherein number of symbols per slot is 14 if subcarrier spacing is 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz. 
     
     
         7 . The method of  claim 1 , wherein duration of the subframe is 1 ms. 
     
     
         8 . A method performed by a base station, the method comprising:
 transmitting to a User Equipment (UE), information indicating a number of slots k;   performing a transmission of a PDSCH (Physical Downlink Shared Channel) to the UE; and   receiving from the UE, HARQ-ACK (Hybrid Automatic Repeat Request) information corresponding to the PDSCH, in a PUCCH (Physical Uplink Control Channel),   wherein, if the transmission of the PDSCH is scheduled in a first slot of a first array of slots having a first subcarrier spacing, the PUCCH is received within a second slot of a second array of slots having a second subcarrier spacing,   wherein, if the number of slots k equals 0, the second slot corresponds to a last slot, of the second array of slots having the second subcarrier spacing, that overlaps with the transmission of the PDSCH,   wherein, if the number of slots k is equal to or larger than 1, the second slot is positioned the number of slots k after the last slot, of the second array of slots having the second subcarrier spacing, that overlaps with the transmission of the PDSCH,   wherein the first subcarrier spacing and the second subcarrier spacing are mutually different, and   wherein a number of slots per subframe depends on each value of the first subcarrier spacing and the second subcarrier spacing.   
     
     
         9 . The method of  claim 8 , wherein the first subcarrier spacing is larger than the second subcarrier spacing. 
     
     
         10 . The method of  claim 8 , wherein the second subcarrier spacing is larger than the first subcarrier spacing 
     
     
         11 . The method of  claim 8 , wherein the information indicating the number of slots k is indicated by dynamic control information, if present, or provided by higher layer signaling. 
     
     
         12 . The method of  claim 8 , wherein the base station transmits the information indicating the number of slots k by higher layer signaling. 
     
     
         13 . The method of  claim 8 , wherein number of symbols per slot is 14 if subcarrier spacing is 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz. 
     
     
         14 . The method of  claim 8 , wherein duration of the subframe is 1 ms. 
     
     
         15 . A base station comprising:
 at least one processor; and   at least one memory connected to the at least one processor,   wherein the at least one processor is configured to:
 transmit to a User Equipment (UE), information indicating a number of slots k; 
 perform a transmission of a PDSCH (Physical Downlink Shared Channel) to the UE; and 
 receive from the UE, HARQ-ACK (Hybrid Automatic Repeat Request) information corresponding to the PDSCH, in a PUCCH (Physical Uplink Control Channel), 
   wherein, if the transmission of the PDSCH is scheduled in a first slot of a first array of slots having a first subcarrier spacing, the PUCCH is received within a second slot of a second array of slots having a second subcarrier spacing,   wherein, if the number of slots k equals 0, the second slot corresponds to a last slot, of the second array of slots having the second subcarrier spacing, that overlaps with the transmission of the PDSCH,   wherein, if the number of slots k is equal to or larger than 1, the second slot is positioned the number of slots k after the last slot, of the second array of slots having the second subcarrier spacing, that overlaps with the transmission of the PDSCH,   wherein the first subcarrier spacing and the second subcarrier spacing are mutually different, and   wherein a number of slots per subframe depends on each value of the first subcarrier spacing and the second subcarrier spacing.   
     
     
         16 . The base station of  claim 15 , wherein the first subcarrier spacing is larger than the second subcarrier spacing. 
     
     
         17 . The base station of  claim 15 , wherein the second subcarrier spacing is larger than the first subcarrier spacing 
     
     
         18 . The base station of  claim 15 , wherein the information indicating the number of slots k is indicated by dynamic control information, if present, or provided by higher layer signaling. 
     
     
         19 . The base station of  claim 15 , wherein the at least one processor is configured to transmit the information indicating the number of slots k by higher layer signaling. 
     
     
         20 . The base station of  claim 15 , wherein number of symbols per slot is 14 if subcarrier spacing is 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz.
