Downlink reception and beam management
Wireless communications may comprise communications between a base station and a wireless device. The base station may send and/or schedule one or more transmissions to the wireless device that may overlap in time. The wireless device may receive and/or decode overlapping transmissions that are associated with a different indication and/or the wireless device may not receive at least one of overlapping transmissions that are associated with the same indications.
1. A method comprising:
receiving, by a wireless device, first downlink control information (DCI) scheduling a first physical downlink shared channel (PDSCH) transmission associated with a first control resource set (CORESET) group index;
receiving second DCI activating a scheduling configuration associated with a second CORESET group index, wherein the first PDSCH transmission overlaps in time with a semi-persistent scheduling (SPS) PDSCH transmission associated with the scheduling configuration;
receiving the first PDSCH transmission; and
determining, based on whether the first CORESET group index and the second CORESET group index are different values, whether to receive the SPS PDSCH transmission.
2. The method of claim 1 , further comprising:
receiving, based on the first CORESET group index and the second CORESET group index being different values, the SPS PDSCH transmission; and
sending an acknowledgement of reception of the first PDSCH transmission and the SPS PDSCH transmission.
3. The method of claim 1 , further comprising:
not receiving, based on the first CORESET group index and the second CORESET group index being a same value, the SPS PDSCH transmission.
4. The method of claim 3 , wherein the not receiving the SPS PDSCH transmission comprises at least one of:
discarding the SPS PDSCH transmission from a buffer; or
refraining from decoding the SPS PDSCH transmission.
5. The method of claim 1 , wherein the first CORESET group index and the second CORESET group index are the same value, wherein the receiving the first PDSCH transmission is based on a determination that the first PDSCH transmission has a higher priority than the SPS PDSCH transmission, and wherein the method further comprises not receiving the SPS PDSCH transmission.
6. The method of claim 1 , wherein the determining whether to receive the SPS PDSCH transmission is further based on a capability of the wireless device for simultaneous reception of at least two transmissions.
7. The method of claim 1 , wherein the first PDSCH transmission overlaps in time with the SPS PDSCH transmission by partially overlapping in time with the SPS PDSCH transmission in at least one of:
a symbol;
a slot; or
a subframe.
8. The method of claim 1 , wherein the first DCI scheduling the first PDSCH is received via a first CORESET, and wherein the second DCI scheduling the SPS PDSCH is received via a second CORESET.
9. The method of claim 1 , wherein:
a cyclic redundancy check (CRC) of the first DCI is scrambled by a first radio network temporary identifier (RNTI); and
a CRC of the second DCI is scrambled by a second RNTI.
10. A method comprising:
receiving, by a wireless device, first downlink control information (DCI) scheduling a first physical downlink shared channel (PDSCH) transmission associated with a first control resource set (CORESET) group index;
receiving second DCI activating a scheduling configuration associated with a second CORESET group index, wherein the first PDSCH transmission overlaps in time with a semi-persistent scheduling (SPS) PDSCH transmission associated with the scheduling configuration;
receiving the first PDSCH transmission; and
receiving, based on the first CORESET group index and the second CORESET group index being different, the SPS PDSCH transmission.
11. The method of claim 10 , wherein the receiving the SPS PDSCH transmission is further based on a capability of the wireless device for simultaneous reception of at least two transmissions.
12. The method of claim 10 , wherein the first PDSCH transmission partially overlaps in time with the SPS PDSCH transmission in at least one of:
a symbol;
a slot; or
a subframe.
13. The method of claim 10 , wherein the first DCI scheduling the first PDSCH is received via a first CORESET and a cyclic redundancy check (CRC) of the first DCI is scrambled by a first radio network temporary identifier (RNTI) and wherein the second DCI scheduling the SPS PDSCH is received via a first CORESET and CRC of the second DCI is scrambled by a second RNTI.
14. The method of claim 10 , wherein:
a cyclic redundancy check (CRC) of the first DCI is scrambled by a first radio network temporary identifier (RNTI); and
a CRC of the second DCI is scrambled by a second RNTI.
15. The method of claim 10 , further comprising:
sending an acknowledgement of reception of the first PDSCH transmission and the SPS PDSCH transmission.
16. The method of claim 10 , wherein the receiving the first PDSCH transmission is based on a determination that the first PDSCH transmission has a higher priority than the SPS PDSCH transmission.
17. A method comprising:
sending, by a base station to a wireless device via a first control resource set (CORESET) associated with a first CORESET group index, first downlink control information (DCI) scheduling a first physical downlink shared channel (PDSCH) transmission;
sending, based on a capability of the wireless device and via a second CORESET associated with a second CORESET group index, second DCI activating a scheduling configuration associated with the second CORESET group index, wherein the first PDSCH transmission overlaps in time with a semi-persistent scheduling (SPS) PDSCH transmission associated with the scheduling configuration, and wherein the first CORESET group index is different from the second CORESET group index;
sending the first PDSCH transmission and the SPS PDSCH transmission overlapping in time; and
receiving, from the wireless device, an acknowledgement of reception of the first PDSCH transmission and the SPS PDSCH transmission.
18. The method of claim 17 , further comprising:
receiving, from the wireless device, an indication of the capability of the wireless device, wherein the capability comprises a capability of the wireless device for simultaneous reception of at least two transmissions.
19. The method of claim 17 , wherein the first PDSCH transmission overlaps in time with the SPS PDSCH transmission by partially overlapping in time with the SPS PDSCH transmission in at least one of:
a symbol;
a slot; or
a subframe.
20. The method of claim 17 , wherein:
a cyclic redundancy check (CRC) of the first DCI is scrambled by a first radio network temporary identifier (RNTI); and
a CRC of the second DCI is scrambled by a second RNTI.
