Method for transmitting and receiving physical downlink shared channel in wireless communication system and device supporting same
Disclosed are a method of transmitting and receiving a physical downlink shared channel in a wireless communication system and an apparatus supporting the method. More specifically, the method performed by a user equipment may comprise transmitting, to a base station (BS), capability information including first information indicating support for a PDSCH repetition-related operation; receiving, from the BS, an higher layer signal including second information for configuring whether to enable the PDSCH repetition-related operation; receiving Downlink Control Information (DCI) related to reception of a PDSCH repetition from the BS when the second information is configured as enable; and receiving the PDSCH repeatedly from the BS based on the DCI.
1. A method of receiving, by a user equipment (UE), a Physical Downlink Shared Channel (PDSCH) in a wireless communication system, the method comprising:
transmitting, to a base station (BS), capability information including first information indicating whether to support an operation related to three types of PDSCH repetition and, second information indicating whether to support a configuration of a control region,
wherein the three types of PDSCH repetition comprise a subframe-based PDSCH repetition indicated by a first parameter, a slot-based PDSCH repetition indicated by a second parameter, and a subslot-based PDSCH repetition indicated by a third parameter, and
wherein the UE is capable of operating according any one of the three types of PDSCH repetition;
receiving, from the BS, information for enabling the operation related to a Hybrid Automatic Repeat and Request (HARQ)-less/blind subframe-based PDSCH repetition;
receiving, from the BS, configuration information for the control region via a higher layer signaling;
based on the configuration information, receiving, from the BS, Downlink Control Information (DCI) related to the HARQ-less/blind subframe-based PDSCH repetition in the control region; and
repeatedly receiving, from the BS, the PDSCH based on the DCI.
2. The method of claim 1 , wherein the operation related to the three types of PDSCH repetition is supported based on configuration of the control region being supported.
3. A user equipment (UE) receiving a Physical Downlink Shared Channel (PDSCH) in a wireless communication system, the UE comprising:
at least one transceiver transmitting and receiving a wireless signal; and
at least one processor functionally connected to the at least one transceiver,
wherein the at least one processor controls to:
transmit, to a base station (BS), capability information including first information indicating whether to support an operation related to three types of PDSCH repetition and, second information indicating whether to support a configuration of a control region,
wherein the three types of PDSCH repetition comprise a subframe-based PDSCH repetition indicated by a first parameter, a slot-based PDSCH repetition indicated by a second parameter, and a subslot-based PDSCH repetition indicated by a third parameter, and
wherein the UE is capable of operating according any one of the three types of PDSCH repetition;
receive, from the BS, information for enabling the operation related to a Hybrid Automatic Repeat and Request (HARQ)-less/blind PDSCH repetition;
receive, from the BS, configuration information for the control region via a higher layer signaling;
based on the configuration information, receive, from the BS, Downlink Control Information (DCI) related to the HARQ-less/blind subframe-based PDSCH repetition in the control region; and
repeatedly receive, from the BS, the PDSCH based on the DCI.
4. The UE of claim 3 , wherein the operation related to the three types of PDSCH repetition is supported based on configuration of the control region being supported.
5. A base station (BS) transmitting a Physical Downlink Shared Channel (PDSCH) in a wireless communication system, the BS comprising:
at least one transceiver transmitting and receiving a wireless signal; and
at least one processor functionally connected to the at least one transceiver,
wherein the at least one processor controls to:
receive, from a user equipment (UE), capability information including first information indicating whether to support an operation related to three types of PDSCH repetition and, second information indicating whether to support a configuration of a control region,
wherein the three types of PDSCH repetition comprise a subframe-based PDSCH repetition indicated by a first parameter, a slot-based PDSCH repetition indicated by a second parameter, and a subslot-based PDSCH repetition indicated by a third parameter, and
wherein the UE is capable of operating according any one of the three types of PDSCH repetition;
transmit, to the UE, information for enabling the operation related to a Hybrid Automatic Repeat and Request (HARQ)-less/blind subframe-based PDSCH repetition;
transmit, to the UE, configuration information for the control region via a higher layer signaling;
based on the configuration information, transmit, to the UE, Downlink Control Information (DCI) related to the HARQ-less/blind subframe-based PDSCH repetition in the control region; and
repeatedly transmit the PDSCH to the UE.
6. The BS of claim 5 , wherein the operation related to the three types of PDSCH repetition is supported based on configuration of the control region being supported.
