Method for operating terminal and base station in wireless communication system, and device supporting same
The present disclosure provides a method for operating a terminal and a base station in a wireless communication system, and a device supporting same. According to an embodiment applicable to the present disclosure, a terminal may acquire data information from at least one transmission reception point (TRP) among a plurality of TRPs on the basis of a transmission mode configured on the terminal by a base station, in which data generated from the same information is transmitted from the plurality of TRPs.
1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving information for configuring a scheme related to two physical downlink shared channel (PDSCH) transmission occasions of a same transport block (TB);
receiving downlink control information (DCI), wherein two transmission configuration indicator (TCI) states are indicated in a codepoint of a TCI field in the DCI, and mapping between the two TCI states and the codepoint of the TCI field is applied based on an activation command; and
receiving two PDSCHs based on the two PDSCH transmission occasions and the two TCI states,
wherein a combination of redundancy version (RV) values for the two PDSCH transmission occasions is determined based on a RV field in the DCI, and
wherein a number of transmission occasions is derived based on the two TCI states being indicated by the TCI field.
2. The method according to claim 1 ,
wherein the two PDSCH transmission occasions include a first transmission occasion and a second transmission occasion, and
wherein the RV field in the DCI is a RV value for the first transmission occasion, and a RV value for the second transmission occasion is determined based on the RV value for the first transmission occasion.
3. The method according to claim 1 ,
wherein each of the two TCI states is related to one reference signal (RS) set, and
wherein each of the two TCI states is associated to one of the two PDSCH transmission occasions.
4. The method according to claim 1 ,
wherein the information for configuring the scheme is received through higher-layer signaling including radio resource control (RRC) signaling.
5. The method according to claim 1 ,
wherein the DCI includes a cyclic redundancy check (CRC) scrambled with a radio network temporary identifier (RNTI) for receiving the two PDSCHs.
6. The method according to claim 1 ,
wherein the two PDSCHs include a plurality of codewords generated from the same TB.
7. A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
at least one transmitter;
at least one receiver;
at least one processor; and
at least one memory operatively coupled to the at least one processor and storing instructions which when executed, cause the at least one processor to perform operations comprising:
receiving information for configuring a scheme related to two physical downlink shared channel (PDSCH) transmission occasions of a same transport block (TB);
receiving downlink control information (DCI), wherein two transmission configuration indicator (TCI) states are indicated in a codepoint of a TCI field in the DCI, and mapping between the two TCI states and the codepoint of the TCI field is applied based on an activation command; and
receiving two PDSCHs based on the two PDSCH transmission occasions and the two TCI states,
wherein a combination of redundancy version (RV) values for the two PDSCH transmission occasions is determined based on a RV field in the DCI, and
wherein a number of transmission occasions is derived based on the two TCI states being indicated by the TCI field.
8. The UE according to claim 7 ,
wherein the UE communicates at least one of a mobile terminal, a network, or an autonomous driving vehicle other than a vehicle including the UE.
9. A memory operably connectable to a processor and storing instructions that, when executed by the processor, control a user equipment (UE) to perform operations in a wireless communication system, the operations comprising:
receiving information for configuring a scheme related to two physical downlink shared channel (PDSCH) transmission occasions of same transport block (TB);
receiving downlink control information (DCI), wherein two transmission configuration indicator (TCI) states are indicated in a codepoint of a TCI field in the DCI, and mapping between the two TCI states and the codepoint of the TCI field is applied based on an activation command; and
receiving two PDSCHs based on the two PDSCH transmission occasions and the two TCI states,
wherein a combination of redundancy version (RV) values for the two PDSCH transmission occasions is determined based on a RV field in the DCI, and
wherein a number of transmission occasions is derived based on the two TCI states being indicated by the TCI field.
