Abstract

The present invention discloses methods for operating a user equipment and a base station in a wireless communication system and devices for supporting the same. More specifically, the present invention provides various embodiments of methods by which a user equipment transmits an uplink signal to a base station and receives feedback information on the uplink signal in order to transmit and receive signals to and from the base station.

Claims (45)

1 . A method comprising:

receiving, via higher layer signaling, configuration information includes (i) first information related to a number of repetitions, and (ii) second information related to a predetermined time period, and (iii) third information related to a redundancy version pattern; and

transmitting a transport block by repetitions across consecutive slots based on the configuration information,

wherein the repetitions based on the first information is applied to transmission of the transport block,

wherein the third information is applied to the repetitions,

wherein an initial transmission of the transport block starts at a transmission occasion among total transmission occasions for the repetitions,

wherein the initial transmission is performed other than earliest transmission occasion among the total transmission occasions for the repetitions, and

wherein the repetitions are terminated at a last transmission occasion among the total transmission occasions for the repetitions based on the second information.

2 . The method of claim 1 , wherein the predetermined time period is associated with a single hybrid automatic repeat request (HARQ) process identity (ID), and the single HARQ process ID is determined based on the initial transmission.

3 . The method of claim 1 , wherein the repetitions are performed based on transmission occasions configured without dynamic scheduling.

4 . The method of claim 2 , further comprising:

obtaining ACKnowledgement/Non-ACKnowledgement (ACK/NACK) feedback for the repetitions.

5 . The method of claim 4 , wherein obtaining the ACK/NACK feedback for the repetitions comprises:

based on not receiving the ACK/NACK feedback corresponding to the single HARQ process ID, determining that the ACK/NACK feedback for the repetitions of the transport block transmission is ACK.

6 . The method of claim 5 , further comprising:

based on receiving NACK as the ACK/NACK feedback for the repetitions, performing retransmission of the transport block transmission.

7 . The method of claim 1 , wherein a redundancy version for the repetitions is determined based on each transmission occasion for the repetitions.

8 . A user equipment (UE) comprising:

at least one transceiver;

at least one processor; and

at least one memory operably coupled with the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:

receiving, via higher layer signaling, configuration information includes (i) first information related to a number of repetitions, and (ii) second information related to a predetermined time period, and (iii) third information related to a redundancy version pattern; and

transmitting a transport block by repetitions across consecutive slots based on the configuration information,

wherein the repetitions based on the first information is applied to transmission of the transport block,

wherein the third information is applied to the repetitions,

wherein an initial transmission of the transport block starts at a transmission occasion among total transmission occasions for the repetitions,

wherein the initial transmission is performed other than earliest transmission occasion among the total transmission occasions for the repetitions, and

wherein the repetitions are terminated at a last transmission occasion among the total transmission occasions for the repetitions based on the second information.

9 . The UE of claim 8 , wherein the predetermined time period is associated with a single hybrid automatic repeat request (HARQ) process identity (ID), and the single HARQ process ID is determined based on the initial transmission.

10 . The UE of claim 8 , wherein the repetitions are performed based on transmission occasions configured without dynamic scheduling.

11 . The UE of claim 9 , wherein the operations further comprise:

obtaining ACKnowledgement/Non-ACKnowledgement (ACK/NACK) feedback for the repetitions.

12 . The UE of claim 11 , wherein obtaining the ACK/NACK feedback for the repetitions comprises:

based on not receiving the ACK/NACK feedback corresponding to the single HARQ process ID, determining that the ACK/NACK feedback for the repetitions of the transport block transmission is ACK.

13 . The UE of claim 12 , wherein the operations further comprise:

based on receiving NACK as the ACK/NACK feedback for the repetitions, performing retransmission of the transport block transmission.

14 . The UE of claim 8 , wherein a redundancy version for the repetitions is determined based on each transmission occasion for the repetitions.

15 . At least one memory operably coupled with at least one processor and storing instructions that, when executed, cause the at least one processor to control a user equipment (UE), the operations comprising:

receiving, via higher layer signaling, configuration information includes (i) first information related to a number of repetitions, and (ii) second information related to a predetermined time period, and (iii) third information related to a redundancy version pattern; and

transmitting a transport block by repetitions across consecutive slots based on the configuration information,

wherein the repetitions based on the first information is applied to transmission of the transport block,

wherein the third information is applied to the repetitions,

wherein an initial transmission of the transport block starts at a transmission occasion among total transmission occasions for the repetitions,

wherein the initial transmission is performed other than earliest transmission occasion among the total transmission occasions for the repetitions, and

wherein the repetitions are terminated at a last transmission occasion among the total transmission occasions for the repetitions based on the second information.
