Common search space repetition
A wireless device selects a first a synchronization signal block (SSB), among SSBs of a cell, based on a signal quality measurement of the SSBs, and a second SSB, of the SSBs, based on the first SSB and a multiplexing pattern. The wireless device determines, based on the first SSB and the second SSB, monitoring occasions associated with a control resource set (coreset) to receive repetitions of downlink control information (DCI). The wireless device receives, via the determined monitoring occasions, one or more of the repetitions of the DCI.
1 . A method comprising:
receiving, by a wireless device, one or more messages indicating a multiplexing pattern between a control resource set (coreset) and synchronization signal blocks (SSBs) of a cell, wherein the multiplexing pattern indicates a mapping of each of the SSBs to respective monitoring occasions associated with the coreset;
selecting, by the wireless device, an SSB, among the SSBs of the cell, based on signal quality measurements of the SSBs;
based on the multiplexing pattern, receiving, via monitoring occasions, one or more repetitions of a downlink control information (DCI), wherein:
each of the one or more repetitions of the DCI comprises a same information; and
the monitoring occasions are associated with the SSB and the coreset; and
receiving, based on the receiving the one or more of the repetitions of the DCI, a system information block.
2 . The method of claim 1 , where the one or more messages further indicate:
the coreset; and
a control channel repetition.
3 . The method of claim 1 , wherein the multiplexing pattern is one of:
a first multiplexing pattern in which a first SSB and a corresponding coreset are scheduled in different times;
a second multiplexing pattern in which a second SSB and the corresponding coreset are scheduled in overlapped times; or
a third multiplexing pattern in which a third SSB and the corresponding coreset are scheduled in partially overlapped times.
4 . The method of claim 1 , wherein the one or more messages further indicate a field indicating repetitions of the DCI.
5 . The method of claim 4 , wherein the receiving, via the monitoring occasions, the one or more repetitions of the DCI is further based on the field indicating the repetitions of the DCI.
6 . The method of claim 5 , wherein the receiving the one or more repetitions of the DCI is further based on the wireless device supporting a coverage enhancement.
7 . The method of claim 1 , wherein the monitoring occasions are during two consecutive slots.
8 . The method of claim 1 , wherein the one or more messages are broadcast messages.
9 . The method of claim 1 , wherein the one or more messages are at least one of:
master information block (MIB); or
a physical broadcast channel (PBCH).
10 . 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 one or more messages indicating a multiplexing pattern between a control resource set (coreset) and synchronization signal blocks (SSBs) of a cell, wherein the multiplexing pattern indicates a mapping of each of the SSBs to respective monitoring occasions associated with the coreset;
select an SSB, among the SSBs of the cell, based on signal quality measurements of the SSBs;
based on the multiplexing pattern, receive, via monitoring occasions, one or more repetitions of a downlink control information (DCI), wherein:
each of the one or more repetitions of the DCI comprises a same information; and
the monitoring occasions are associated with the SSB and the coreset; and
receive, based on receiving the one or more of the repetitions of the DCI, a system information block.
11 . The wireless device of claim 10 , wherein the one or more messages for the cell further indicate:
the coreset; and
a control channel repetition.
12 . The wireless device of claim 10 , wherein the multiplexing pattern is one of:
a first multiplexing pattern in which a first SSB and a corresponding coreset are scheduled in different times;
a second multiplexing pattern in which a second SSB and the corresponding coreset are scheduled in overlapped times; or
a third multiplexing pattern in which a third SSB and the corresponding coreset are scheduled in partially overlapped times.
13 . The wireless device of claim 10 , wherein the one or more messages further indicate a field indicating repetitions of the DCI.
14 . The wireless device of claim 13 , wherein receiving, via the monitoring occasions, the one or more repetitions of the DCI is further based on the field indicating the repetitions of the DCI.
15 . The wireless device of claim 10 , wherein the monitoring occasions are during two consecutive slots.
16 . The wireless device of claim 10 , wherein the one or more messages are broadcast messages.
17 . 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 one or more messages indicating a multiplexing pattern between a control resource set (coreset) and synchronization signal blocks (SSBs) of a cell, wherein the multiplexing pattern indicates a mapping of each of the SSBs to respective monitoring occasions associated with the coreset;
select an SSB, among the SSBs of the cell, based on signal quality measurements of the SSBs;

the monitoring occasions are associated with the SSB and the coreset; and
receive, based on receiving the one or more of the repetitions of the DCI, a system information block.
18 . The non-transitory computer-readable medium of claim 17 , wherein the one or more messages for the cell further indicate:
the coreset; and
a control channel repetition.
