Abstract

Claims (61)

1 . A method comprising:

receiving downlink control information (DCI), wherein the DCI indicates a resource for reception of a transport block;

selecting a transmission configuration indicator (TCI) state among a first TCI state associated with a first set of transmission time intervals (TTIs) and a second TCI state associated with a second set of TTIs, based on which of the first set of TTIs or the second set of TTIs overlaps in time with the resource indicated by the DCI; and

receiving the transport block via the resource, based on the selected TCI state.

2 . The method of claim 1 , further comprising receiving configuration parameters, wherein the configuration parameters indicate the first set of TTIs and the second set of TTIs.

3 . The method of claim 1 , wherein the first TCI state is associated with a first transmission and reception point (TRP).

4 . The method of claim 3 , wherein the second TCI state is associated with a second transmission and reception point (TRP).

5 . The method of claim 1 , further comprising receiving a second DCI, wherein the second DCI comprises a resource assignment,

wherein the resource assignment indicates:

a third TCI state associated with the first set of TTIs,

a fourth TCI state associated with the second set of TTIs,

a first resource for a first physical downlink shared channel (PDSCH), wherein a first gap between the second DCI and the first resource is smaller than a threshold value,

a second resource for a second PDSCH, wherein a second gap between the second DCI and the second resource is equal to or larger than the threshold value, and

a third resource for a third PDSCH, wherein a third gap between the second DCI and the third resource is larger than the second gap.

6 . The method of claim 5 , further comprising:

receiving the first PDSCH based on a default TCI state, wherein the default TCI state is determined based on a TCI state of a control resource set (coreset) monitored by the wireless device in a most recent slot before the first resource;

receiving the second PDSCH based on the third TCI state; and

receiving the third PDSCH based on the fourth TCI state.

7 . The method of claim 5 , further comprising receiving the first PDSCH based on a default TCI state,

wherein the default TCI state is the first TCI state in response to receiving the second DCI via a first coreset of a first coreset group, wherein the first set of TTIs is configured for the first coreset group; or

wherein the default TCI state is the second TCI state in response to receiving the second DCI via a second coreset of a second coreset group, wherein the second set of TTIs is configured for the second coreset group.

8 . The method of claim 5 ,

wherein the threshold value is determined based on a wireless device capability; and

wherein the wireless device transmits the wireless device capability to a base station.

9 . The method of claim 1 , further comprising determining the first set of TTIs for the first coreset group, based on one or more first search spaces associated with one or more first coresets of a first coreset group.

10 . The method of claim 9 , further comprising:

determining the first set of TTIs comprise one or more first slots, wherein the wireless device monitors DCis via the one or more first search spaces of the first coreset group during the one or more first slots; and

determining the second set of TTIs comprise one or more second slots, wherein the one or more first slots do not comprise the one or more second slots.

11 . A wireless device comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the wireless device to:

receive downlink control information (DCI), wherein the DCI indicates a resource for reception of a transport block;

select a transmission configuration indicator (TCI) state among a first TCI state associated with a first set of transmission time intervals (TTIs) and a second TCI state associated with a second set of TTIs, based on which of the first set of TTIs or the second set of TTIs overlaps in time with the resource indicated by the DCI; and

receive the transport block via the resource based on the selected TCI state.

12 . The wireless device of claim 11 , wherein the instructions further cause the wireless device to receive configuration parameters indicating the first set of TTIs and the second set of TTIs.

13 . The wireless device of claim 11 , wherein the first TCI state is associated with a first transmission and reception point (TRP).

14 . The wireless device of claim 13 , wherein the second TCI state is associated with a second transmission and reception point (TRP).

15 . The wireless device of claim 11 ,

wherein the instructions further cause the wireless device to receive a second DCI;

wherein the second DCI comprises a resource assignment;

wherein the resource assignment indicates a third TCI state associated with the first set of TTIs;

wherein the resource assignment indicates a fourth TCI state associated with the second set of TTIs;

wherein the resource assignment indicates a first resource for a first physical downlink shared channel (PDSCH), wherein a first gap between the second DCI and the first resource is smaller than a threshold value;

wherein the resource assignment indicates a second resource for a second PDSCH, wherein a second gap between the second DCI and the second resource is equal to or larger than the threshold value; and

wherein the resource assignment indicates a third resource for a third PDSCH, wherein a third gap between the second DCI and the third resource is larger than the second gap.

16 . The wireless device of claim 15 , wherein the instructions further cause the wireless device to receive:

the first PDSCH based on a default TCI state, wherein the default TCI state is determined based on a TCI state of a control resource set (coreset) monitored by the wireless device in a most recent slot before the first resource;

the second PDSCH based on the third TCI state; and the third PDSCH based on the fourth TCI state.

17 . The wireless device of claim 15 , wherein the instructions further cause the wireless device to receive the first PDSCH based on a default TCI state,

wherein the default TCI state is the first TCI state in response to receiving the second DCI via a first coreset of a first coreset group, wherein the first set of TTIs is configured for the first coreset group; or

wherein the default TCI state is the second TCI state in response to receiving the second DCI via a second coreset of a second coreset group, wherein the second set of TTIs is configured for the second coreset group.

18 . The wireless device of claim 15 , wherein the threshold value is determined based on a wireless device capability; and wherein the wireless device transmits the wireless device capability to a base station.
