Abstract

Claims (45)

1 . A method comprising:

receiving, by a user equipment (UE) from a base station, configuration information related to a plurality of sounding reference signal (SRS) resource sets;

receiving, by the UE from the base station, downlink control information (DCI) including first information related to one of a first SRS resource set, a second SRS resource set, or the first SRS resource set and the second SRS resource set; and

performing uplink repetition transmission across K consecutive slots based on the first information,

wherein a number of SRS resources included in the first SRS resource set and the second SRS resource set are same, and

wherein, based on the first SRS resource set and the second SRS resource set being related to the first information and the K being 2, the first SRS resource set is applied to a first slot of the K consecutive slots and the second SRS resource set is applied to a second slot of the K consecutive slots.

2 . The method of claim 1 , wherein:

based on the first SRS resource set and the second SRS resource set being related to the first information, a number of layers of first uplink repetition transmission associated with the first SRS resource set and a number of layers of second uplink repetition transmission associated with the second SRS resource set are same.

3 . The method of claim 2 , wherein:

one SRS port is configured for each of at least one SRS resource in the first SRS resource set and the second SRS resource set.

4 . The method of claim 2 , wherein:

the first uplink repetition transmission associated with the first SRS resource set and the second uplink repetition transmission associated with the second SRS resource set are in different slots of the K consecutive slots.

5 . The method of claim 1 , wherein:

based on the first SRS resource set being related to the first information or the second SRS resource set being not related to first information, the uplink repetition transmission is performed across the K consecutive slots based on at least one SRS resource indicated among the first SRS resource set.

6 . The method of claim 1 , wherein:

based on the second SRS resource set being related to the first information or the first SRS resource set being not related to the first information, the uplink repetition transmission is performed across the K consecutive slots based on at least one SRS resource among the second SRS resource set.

7 . The method of claim 1 , wherein:

the first SRS resource set corresponds to a first associated non-zero power (NZP) channel state information-reference signal (CSI-RS) resource, and

the second SRS resource set corresponds to a second associated NZP CSI-RS resource.

8 . The method of claim 1 , wherein:

the uplink repetition transmission is a non-codebook-based transmission or a codebook-based transmission.

9 . The method of claim 1 , wherein:

the DCI includes second information related to at least one SRS resource in at least one SRS resource set related to the first information, and

the first information and the second information are indicated by different fields included in the DCI.

10 . The method of claim 9 , wherein:

the second information is indicated by a first field and a second field,

the first field indicates at least one SRS resource among the first SRS resource set, and

the second field indicates at least one SRS resource among the second SRS resource set.

11 . The method of claim 1 , wherein:

the uplink repetition transmission includes a physical uplink shared channel (PUSCH) repetition transmission.

12 . A user equipment (UE) comprising:

at least one transceiver; and

at least one processor connected to the at least one transceiver,

wherein the processor is configured to:

receive, from a base station through the at least one transceiver, configuration information related to a plurality of sounding reference signal (SRS) resource sets;

receive, from the base station through the at least one transceiver, downlink control information (DCI) including first information related to one of a first SRS resource set, a second SRS resource set, or the first SRS resource set and the second SRS resource set; and

perform uplink repetition transmission across K consecutive slots based on the first information,

wherein a number of SRS resources included in the first SRS resource set and the second SRS resource set are same, and

wherein, based on the first SRS resource set and the second SRS resource set being related to the first information and the K being 2, the first SRS resource set is applied to a first slot of the K consecutive slots and the second SRS resource set is applied to a second slot of the K consecutive slots.

13 . A method comprising:

transmitting, by a base station to a user equipment (UE), configuration information related to a plurality of sounding reference signal (SRS) resource sets;

transmitting, by the base station to the UE, downlink control information (DCI) including first information related to one of a first SRS resource set, a second SRS resource set, or the first SRS resource set and the second SRS resource set; and

performing uplink repetition reception transmitted across K consecutive slots based on the first information,

wherein a number of SRS resources included in the first SRS resource set and the second SRS resource set are same, and

wherein, based on the first SRS resource set and the second SRS resource set being related to the first information and the K being 2, the first SRS resource set is applied to a first slot of the K consecutive slots and the second SRS resource set is applied to a second slot of the K consecutive slots.
