Method for transmitting and receiving data in wireless communication system and apparatus therefor
The present disclosure provides a method for a terminal to receive a physical downlink shared channel (PDSCH) in a wireless communication system supporting a narrow band-internet of things (NB-IoT). Specifically, the terminal receives a first physical downlink control channel (PDCCH) including first downlink control information (DCI) from a base station and receives a first PDSCH on the basis of the first DCI. Here, the first PDSCH may include indication information indicating whether a multi transport block is scheduled. The terminal receives a plurality of PDSCHs from the base station, wherein at least one PDSCH of the plurality of PDSCHs may be received without receiving a separate DCI according to the indication information.
1. A method for receiving, by a user equipment (UE), multiple transport blocks in a wireless communication system supporting a narrow band-Internet of things (NB-IoT), the method comprising:
receiving, from a base station, configuration information transmitted via a single cell-multicast control channel (SC-MCCH);
receiving, from the base station, Downlink Control Information (DCI); and
receiving multiple transport blocks based on the DCI,
wherein the configuration information includes a configuration of each single cell-traffic channel (SC-MTCH) related to scheduling of the multiple transport blocks.
2. The method of claim 1 , wherein the DCI includes information for a number of the multiple transport blocks.
3. The method of claim 2 ,
wherein a cyclic redundancy check (CRC) of the DCI is scrambled with group-radio network temporary identifier (G-RNTI).
4. The method of claim 2 ,
wherein a number of transport blocks scheduled for the SC-MTCH is indicated based on the information for the number of the multiple transport blocks.
5. The method of claim 2 ,
wherein the maximum number of the multiple transport blocks is pre-defined.
6. The method of claim 1 ,
wherein the multiple transport blocks are received via narrow band physical shared channel (NPDSCH).
7. The method of claim 1 ,
wherein the configuration information further includes information indicating a scheduling gap between transport blocks.
8. The method of claim 7 ,
wherein a scheduling gap between two consecutively transmitted transport blocks among the multiple transport blocks is configured based on the information indicating the scheduling gap.
9. The method of claim 8 ,
wherein a number of subframes between a first transport block and a second transport block is indicated as a scheduling gap based on the information indicating the scheduling gap.
10. The method of claim 9 ,
wherein the scheduling gap is a duration from a last subframe at which a NPDSCH including the first transport block is transmitted to a first subframe at which a transmission of a NPDSCH including the second transport block starts.
11. The method of claim 1 ,
wherein the configuration information is related to single cell-point to multipoint (SC-PTM).
12. A user equipment (UE) receiving multiple transport blocks in a wireless communication system supporting a narrow band-Internet of things (NB-IoT), the UE comprising:
a transceiver for transmitting and receiving a radio signal; and
a processor functionally connected to the transceiver,
wherein the processor is configured to:
receive, from a base station, configuration information transmitted via a single cell-multicast control channel (SC-MCCH),
receive, from the base station, Downlink Control Information (DCI), and
receive multiple transport blocks based on the DCI, and
wherein the configuration information includes a configuration of each single cell-traffic channel (SC-MTCH) related to scheduling of the multiple transport blocks.
13. The UE of claim 12 , wherein the DCI includes information for a number of the multiple transport blocks.
14. The UE of claim 13 ,
wherein a cyclic redundancy check (CRC) of the DCI is scrambled with group-radio network temporary identifier (G-RNTI).
15. The UE of claim 12 ,
wherein the configuration information further includes information indicating a scheduling gap between transport blocks.
16. A method transmitting, by a base station, multiple transport blocks in a wireless communication system supporting a narrow band-Internet of things (NB-IoT), the method comprising:
transmitting, to a user equipment(UE), configuration information transmitted via a single cell-multicast control channel (SC-MCCH);
transmitting, to the UE, Downlink Control Information (DCI); and
transmitting multiple transport blocks based on the DCI to the UE,
wherein the configuration information includes a configuration of each single cell-traffic channel (SC-MTCH) related to scheduling of the multiple transport blocks.
17. The method of claim 16 , wherein the DCI includes information for a number of the multiple transport blocks.
18. The method of claim 17 ,
wherein a cyclic redundancy check (CRC) of the DCI is scrambled with group-radio network temporary identifier (G-RNTI).
19. The method of claim 16 ,
wherein the configuration information further includes information indicating a scheduling gap between transport blocks.
20. The method of claim 19 ,
wherein a scheduling gap between two consecutively transmitted transport blocks among the multiple transport blocks is configured based on the information indicating the scheduling gap.
