摘要

A wireless device may receive one or more messages comprise parameters of a first downlink control information (DCI) format and a second DCI format for monitoring on a first search space. The parameters may comprise the second DCI format configured for monitoring on a second search space. The wireless device may determine, based on the first DCI format, a first DCI size of the second DCI format for the first search space. The wireless device may determine, based on the second DCI format, a second DCI size of the second DCI format in the second search space. The wireless device may monitor for a first DCI on the first search space based on the first DCI size. The wireless device may monitor for a second DCI on the second search space based on the second DCI size.

The method of claim 1, wherein the configuration parameters are configured for a bandwidth part of a cell, and wherein the first search space and the second search space are configured for the bandwidth part of the cell.3. The method of claim 2, wherein the first DCI format is used for scheduling data for the cell or is used for scheduling a group common control, and wherein the first DCI is scrambled with a first radio network temporary identifier (RNTI).4. The method of claim 3, wherein the first RNTI is at least one of:a cell RNTI (C-RNTI);a configured scheduling RNTI (CS-RNTI);a modulation and coding scheme C-RNTI (MCS-C-RNTI);a transmission power control physical uplink control channel RNTI (TPC-PUCCH-RNTI);a transmission power control physical uplink shared channel RNTI (TPC-PUSCH-RNTI);a system information RNTI (SI-RNTI);a paging RNTI (P-RNTI); ora semi-persistent channel state information RNTI (SP-CSI-RNTI).5. The method of claim 2, wherein the second DCI format is configured for scheduling data for the cell, and wherein the second DCI is scrambled with a second RNTI.6. The method of claim 5, wherein the second RNTI does not comprise at least one of:a C-RNTI;a CS-RNTI;a MCS-C-RNTI;a TPC-PUCCH-RNTI;a TPC-PUSCH-RNTI;a SI-RNTI;a P-RNTI; ora SP-CSI-RNTI.7. The method of claim 1, further comprising determining the first DCI size of the second DCI format as a DCI size of the first DCI format.8. The method of claim 7, further comprising adding zeros to the second DCI format until the second DCI format has the first DCI size, in response to a size of the second DCI format being smaller than the DCI size of the first DCI format.9. The method of claim 7, further comprising truncating bits of the second DCI format until the second DCI format has the first DCI size, in response to a size of the second DCI format being larger than the DCI size of the first DCI format.10. The method of claim 1, further comprising determining the second DCI size of the second DCI format as a DCI size of the second DCI format.11. A wireless device comprising:one or more processors; andmemory storing instructions that, when executed by the one or more processors, cause the wireless device to:receive, from a base station, one or more radio resource control messages comprising configuration parameters of a cell, the configuration parameters comprising:a first downlink control information (DCI) format and a second DCI format, for monitoring on a first search space; andthe second DCI format for monitoring on a second search space;determine, based on the first DCI format, a first DCI size of the second DCI format for the first search space;determine, based on the second DCI format, a second DCI size of the second DCI format in the second search space;monitor, based on the first DCI size, the first search space for a first DCI, wherein the first DCI is based on the first DCI format or the second DCI format; andmonitor, based on the second DCI size, the second search space for a second DCI, wherein the second DCI is based on the second DCI format.12.
