Method for operating terminal and base station in wireless communication system, and device supporting same
Disclosed are: 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 resource information for setting a transmission mode, in which data generated from the same information is transmitted through a plurality of physical downlink shared channels (PDSCHs) by a base station, and on this basis, transmitting the data through the plurality of PDSCHs; and acquire related data information.
1. A method for operating by a user equipment (UE) in a wireless communication system, the method comprising:
receiving configuration information about a mode for transmitting a plurality of data based on same transport block (TB);
receiving downlink control information (DCI) for scheduling two physical downlink shared channels (PDSCHs) including a first PDSCH and a second PDSCH;
receiving the two PDSCHs based on the configuration information and the DCI,
wherein, based on a unit of resource block (RB) bundling being configured as a wideband:
the first PDSCH is received in a first resource including half of consecutive RBs among total RBs allocated for the UE and
the second PDSCH is received in a second resource including remaining RBs excluding the first resource among the total RBs, and
wherein, based on the unit of the RB bundling being configured as a 2 RBs or 4 RBs:
a total RBs allocated for the UE are divided into a plurality of precoding resource block groups (PRGs), the first PDSCH is received in a first resource including PRGs with even indexes among the plurality of PRGs, and the second PDSCH is received in a second resource including PRGs with odd indexes.
2. The method of claim 1 ,
wherein the DCI further includes two transmission configuration indicator (TCI) states including a first TCI state and a second TCI state, and
wherein the first PDSCH corresponds to the first TCI state and the second PDSCH corresponds to the second TCI state.
3. The method of claim 1 ,
wherein a first phase tracking-reference signal (PT-RS) for the first PDSCH and a second PT-RS for the second PDSCH are mapped based on the first resource and the second resource, respectively.
4. The method of claim 1 ,
wherein the configuration information is received via a higher layer signaling.
5. The method of claim 1 ,
wherein, the two PDSCHs are received from different transmission and reception points (TRPs).
6. The method of claim 2 ,
wherein the first resource corresponds to the first TCI state and the second resource corresponds to the second TCI state.
7. A user equipment (UE) operating in a wireless communication system, comprising:
at least one transmitter;
at least one receiver;
at least one processor; and
at least one memory operably connected to the at least one processor and configured to store instructions for causing the at least one processor to perform a specific operation when executed,
wherein the specific operation comprises:
receiving configuration information about a mode for transmitting a plurality of data based on same transport block (TB);
receiving downlink control information (DCI) for scheduling two physical downlink shared channels (PDSCHs) including a first PDSCH and a second PDSCH;
receiving the two PDSCHs based on the configuration information and the DCI,
wherein, based on a unit of resource block (RB) bundling being configured as a wideband:
the first PDSCH is received in a first resource including half of consecutive RBs among total RBs allocated for the UE and
the second PDSCH is received in a second resource including remaining RBs excluding the first resource among the total RBs, and
wherein, based on the unit of the RB bundling being configured as a 2 RBs or 4 RBs:
a total RBs allocated for the UE are divided into a plurality of precoding resource block groups (PRGs), the first PDSCH is received in a first resource including PRGs with even indexes among the plurality of PRGs, and the second PDSCH is received in a second resource including PRGs with odd indexes.
8. The UE of claim 7 ,
wherein the UE communicates with at least one of a mobile UE, a network, or an autonomous vehicle other than a vehicle containing the UE.
