Multiple-input multiple-output capability information for power savings

A wireless device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, causes the wireless device to:
• transmit, to a base station, one or more first radio resource control (RRC) messages comprising wireless device capability information comprising one or more maximum numbers of multiple-input multiple-output (MIMO) layers for reception of a physical downlink shared channel (PDSCH), of a cell, scheduled by downlink control information (DCI) from each transmit/receive point (TRP) of a plurality of TRPs of the cell;
• receive, from the base station, one or more second RRC messages comprising one or more parameters indicating a first number of MIMO layers, for a first TRP of the plurality of TRPs of the cell, wherein the first number of MIMO layers is equal to or less than a first maximum number of MIMO layers, of the one or more maximum numbers of MIMO layers, corresponding to the first TRP;
• and
• receive, from the base station, one or more transport blocks with a second number of MIMO layers, wherein the second number is equal to or less than the first number.

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:

• transmit, to a base station, one or more first radio resource control (RRC) messages comprising wireless device capability information comprising one or more maximum numbers of multiple-input multiple-output (MIMO) layers for reception of a physical downlink shared channel (PDSCH), of a cell, scheduled by downlink control information (DCI) from each transmit/receive point (TRP) of a plurality of TRPs of the cell;
• receive, from the base station, one or more second RRC messages comprising one or more parameters indicating a first number of MIMO layers, for a first TRP of the plurality of TRPs of the cell, wherein the first number of MIMO layers is equal to or less than a first maximum number of MIMO layers, of the one or more maximum numbers of MIMO layers, corresponding to the first TRP;
• and
• receive, from the base station, one or more transport blocks with a second number of MIMO layers, wherein the second number is equal to or less than the first number.
