Abstract

A wireless device receives downlink control information (DCI) via a transmission reception point of a multiple transmission reception points and a control resource set (coreset) of a plurality of coresets. The wireless device transmits, in response to receiving the DCI, uplink control information via a physical uplink control channel (PUCCH) resource associated with an index of the PUCCH resource. The index is based on a parameter comprising a transmission configuration indication (TCI) state value.

First claim

What is claimed is:

1 . 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) via a transmission reception point of multiple transmission reception points and a control resource set (coreset) of a plurality of coresets; and
transmit, in response to receiving the DCI, uplink control information via a physical uplink control channel (PUCCH) resource associated with an index of the PUCCH resource, wherein the index is based on a parameter comprising a transmission configuration indication (TCI) state value.

2 . The wireless device of claim 1 , wherein the instructions further cause the wireless device to determine the index of the PUCCH resource based on the parameter, wherein transmitting the uplink control information is further in response to determining the index.

3 . The wireless device of claim 1 , wherein the instructions further cause the wireless device to receive one or more configuration parameters indicating the plurality of coresets.

4 . The wireless device of claim 1 , wherein the instructions further cause the wireless device to receive the DCI via one of the plurality of coresets from each of the multiple transmission reception points.

5 . The wireless device of claim 1 , wherein the DCI is received from different transmission reception points of the multiple transmission reception points.

6 . The wireless device of claim 1 , wherein the DCI is received from different coresets from a same transmission reception point of the multiple transmission reception points.

7 . The wireless device of claim 1 , wherein the PUCCH resource comprises one or more PUCCH resources.

8 . The wireless device of claim 7 , wherein the one or more PUCCH resources are from a same PUCCH resource set.

9 . The wireless device of claim 1 , wherein the uplink control information comprises at least one of:
an acknowledgment (ACK); a negative acknowledgment (NACK); a channel state information (CSI); a scheduling request (SR); and a channel quality indication (CQI).

10 . The wireless device of claim 1 , wherein the instructions further cause the wireless device to transmit the uplink control information via the PUCCH resource on one or more orthogonal frequency division multiplexing symbols.

11 . A base station comprising:
one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the base station to:
transmit downlink control information (DCI) via a transmission reception point of multiple transmission reception points and a control resource set (coreset) of a plurality of coresets; and
receive, in response to transmitting the DCI, uplink control information via a physical uplink control channel (PUCCH) resource associated with an index of the PUCCH resource, wherein the index is based on a parameter comprising a transmission configuration indication (TCI) state value.

12 . The base station of claim 11 , wherein the instructions further cause the base station to determine the index of the PUCCH resource based on the parameter, wherein receiving the uplink control information is further in response to determining the index.

13 . The base station of claim 11 , wherein the instructions further cause the base station to transmit one or more configuration parameters indicating the plurality of coresets.

14 . The base station of claim 11 , wherein the instructions further cause the base station to transmit the DCI via one of the plurality of coresets from each of the multiple transmission reception points.

15 . The base station of claim 11 , wherein the DCI is transmitted from different transmission reception points of the multiple transmission reception points.

16 . The base station of claim 11 , wherein the DCI is transmitted from different coresets from a same transmission reception point of the multiple transmission reception points.

17 . The base station of claim 11 , wherein the PUCCH resource comprises one or more PUCCH resources.

18 . The base station of claim 17 , wherein the one or more PUCCH resources are from a same PUCCH resource set.

19 . The base station of claim 11 , wherein the instructions further cause the base station to receive the uplink control information via the PUCCH resource on one or more orthogonal frequency division multiplexing symbols.

20 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:
receive downlink control information (DCI) via a transmission reception point of multiple transmission reception points and a control resource set (coreset) of a plurality of coresets; and transmit, in response to receiving the DCI, uplink control information via a physical uplink control channel (PUCCH) resource associated with an index of the PUCCH resource, wherein the index is based on a parameter comprising a transmission configuration indication (TCI) state value.
