Abstract

A wireless device receives from a base station configuration parameters indicating a first physical downlink shared channel (PDSCH) capability value associated with a first power state of a cell via a first transmission reception point (TRP) and a second PDSCH capability value associated with a second power state of the cell via a second TRP. The wireless device also receives a first downlink control information (DCI) scheduling a first transport block (TB), via a first PDSCH, of the first TRP and a second DCI scheduling a second downlink TB, via a second PDSCH, of the second TRP.

First claim

What is claimed is:

1 . A method comprising:
receiving, by a wireless device from a base station, configuration parameters indicating a first physical downlink shared channel (PDSCH) capability value associated with a first power state of a cell via a first transmission reception point (TRP) and a second PDSCH capability value associated with a second power state of the cell via a second TRP; receiving a first downlink control information (DCI) scheduling a first downlink transport block (TB), via a first PDSCH, of the first TRP; and receiving a second DCI scheduling a second downlink TB, via a second PDSCH, of the second TRP.

2 . The method of claim 1 , wherein the first TRP is associated with a first panel of the wireless device and the second TRP is associated with a second panel of the wireless device.

3 . The method of claim 1 , further comprising the wireless device receiving the first downlink TB via the first TRP and the second downlink TB via the second TRP with at least one of a shared time resource or a shared frequency resource.

4 . The method of claim 1 , wherein the first TRP is identified in the first downlink control information by at least one of:
a TRP identifier; a cell index; or a reference signal index.

5 . The method of claim 4 , wherein the TRP identifier comprises at least on of:
a control resource set group index of a control resource set group from which the DCI is transmitted from the base station on a control resource set; a TRP index indicated in the DCI; or a transmission configuration indication (TCI) state group index of a TCI state group comprising at least one TCI state with which the wireless device receives the first downlink TB.

6 . The method of claim 1 , wherein the wireless device is configured to receive low-latency data packets via the first TRP and configured to receive latency tolerant data packets via the second TRP.

7 . The method of claim 1 , wherein a PDSCH processing time associated with the first PDSCH capability value is smaller than the PDSCH processing time associated with the second PDSCH capability value.

8 . A method comprising:
transmitting, by a base station to a wireless device, configuration parameters indicating a first physical downlink shared channel (PDSCH) capability value associated with a first power state of a cell via a first transmission reception point (TRP) and a second PDSCH capability value associated with a second power state of the cell via a second TRP; transmitting a first downlink control information (DCI) scheduling a first downlink transport block (TB), via a first PDSCH, of the first TRP; and transmitting a second DCI scheduling a second downlink TB, via a second PDSCH, of the second TRP.

9 . The method of claim 8 , wherein the first TRP is associated with a first panel of the wireless device and the second TRP is associated with a second panel of the wireless device.

10 . The method of claim 8 , further comprising the base station transmitting the first downlink TB via the first TRP and the second downlink TB via the second TRP with at least one of a shared time resource or a shared frequency resource.

11 . The method of claim 8 , wherein the first TRP is identified in the first downlink control information by at least one of:
a TRP identifier; a cell index; or a reference signal index.

12 . The method of claim 11 , wherein the TRP identifier comprises at least on of:
a control resource set group index of a control resource set group from which the DCI is transmitted from the base station on a control resource set; a TRP index indicated in the DCI; or a transmission configuration indication (TCI) state group index of a TCI state group comprising at least one TCI state with which the wireless device receives the first downlink TB.

13 . The method of claim 8 , wherein the wireless device is configured to receive low-latency data packets via the first TRP and configured to receive latency tolerant data packets via the second TRP.

14 . The method of claim 8 , wherein a PDSCH processing time associated with the first PDSCH capability value is smaller than the PDSCH processing time associated with the second PDSCH capability value.

15 . A non-transitory computer-readable medium comprising instruction that, when executed by one or more processors of a wireless device, cause the wireless device to:
receive, from a base station, configuration parameters indicating a first physical downlink shared channel (PDSCH) capability value associated with a first power state of a cell via a first transmission reception point (TRP) and a second PDSCH capability value associated with a second power state of the cell via a second TRP; receive a first downlink control information (DCI) scheduling a first transport block (TB), via a first PDSCH, of the first TRP; and receive a second DCI scheduling a second downlink TB, via a second PDSCH, of the second TRP.

16 . The non-transitory computer-readable medium of claim 15 , wherein the first TRP is associated with a first panel of the wireless device and the second TRP is associated with a second panel of the wireless device.

17 . The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the wireless device to receive the first downlink TB via the first TRP and the second downlink TB via the second TRP with at least one of a shared time resource or a shared frequency resource.

18 . The non-transitory computer-readable medium of claim 15 , wherein the first TRP is identified in the first downlink control information by at least one of:
a TRP identifier; a cell index; or a reference signal index.

19 . The non-transitory computer-readable medium of claim 18 , wherein the TRP identifier comprises at least on of:
a control resource set group index of a control resource set group from which a DCI is transmitted from the base station on a control resource set; a TRP index indicated in the DCI; or a transmission configuration indication (TCI) state group index of a TCI state group comprising at least one TCI state with which the wireless device receives the first downlink TB.

20 . The non-transitory computer-readable medium of claim 15 , wherein the wireless device is configured to receive low-latency data packets via the first TRP and configured to receive latency tolerant data packets via the second TRP and a PDSCH processing time associated with the first PDSCH capability value is smaller than the PDSCH processing time associated with the second PDSCH capability value.
