Semi-persistent scheduling confirmation

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 configuration information for a plurality of resource allocations;
• receive downlink control information (DCI) that comprises an indication of activation or release of at least one resource allocation of the plurality of resource allocations;
• and
• send, after receiving the DCI:
• a medium access control (MAC) subheader comprising a logical channel identifier (LCID) that identifies a confirmation MAC control element;
• and
• the confirmation MAC control element comprising a plurality of fields, wherein at least one of the plurality of fields indicates receipt of the indication of activation or release by using a same value to indicate either the activation or the release.

A method comprising:

• sending, by a base station, configuration information for a plurality of resource allocations;
• sending downlink control information (DCI) that comprises an indication of activation or release of at least one resource allocation of the plurality of resource allocations;
• and
• receiving, after sending the DCI:
• a medium access control (MAC) subheader comprising a logical channel identifier (LCD) that identifies a confirmation MAC control element;
• and
• the confirmation MAC control element comprising a plurality of fields, wherein at least one field of the plurality of fields indicates receipt of the indication of activation or release by using a same value to indicate either the activation or the release.

A base station comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the base station to:
• send configuration information for a plurality of resource allocations;
• send downlink control information (DCI) that comprises an indication of activation or release of at least one resource allocation of the plurality of resource allocations;
• and
• receive, after sending the DCI:
• a medium access control (MAC) subheader comprising a logical channel identifier (LCID) that identifies a confirmation MAC control element;
• and
• the confirmation MAC control element comprising a plurality of fields, wherein at least one of the plurality of fields indicates receipt of the indication of activation or release by using a same value to indicate either the activation or the release.

A non-transitory computer-readable medium storing instructions that, when executed, cause a wireless device to:

• receive configuration information for a plurality of resource allocations;
• receive downlink control information (DCI) that comprises an indication of activation or release of at least one resource allocation of the plurality of resource allocations;
• and
• send, after receiving the DCI:
• a medium access control (MAC) subheader comprising a logical channel identifier (LCD) that identifies a confirmation MAC control element;
• and
• the confirmation MAC control element comprising a plurality of fields, wherein at least one of the plurality of fields indicates receipt of the indication of activation or release by using a same value to indicate either the activation or the release.

A non-transitory computer-readable medium storing instructions that, when executed, cause a base station to:

• send configuration information for a plurality of resource allocations;
• send downlink control information (DCI) that comprises an indication of activation or release of at least one resource allocation of the plurality of resource allocations;
• and
• receive, after sending the DCI:
• a medium access control (MAC) subheader comprising a logical channel identifier (LCD) that identifies a confirmation MAC control element;
• and
• the confirmation MAC control element comprising a plurality of fields, wherein at least one of the plurality of fields indicates receipt of the indication of activation or release by using a same value to indicate either the activation or the release.

A system comprising:

• a base station;
• and
• a wireless device,
• wherein the wireless device comprises:
• one or more first processors;
• and
• first memory storing first instructions that, when executed by the one or more first processors, cause the wireless device to:
• receive, from the base station, configuration information for a plurality of resource allocations;
• receive downlink control information (DCI) that comprises an indication of activation or release of at least one resource allocation of the plurality of resource allocations;
• and
• send, after receiving the DCI:
• a medium access control (MAC) subheader comprising a logical channel identifier (LCD) that identifies a confirmation MAC control element;
• and
• the confirmation MAC control element comprising a plurality of fields, wherein at least one of the plurality of fields indicates receipt of the indication of activation or release by using a same value to indicate either the activation or the release, and
• wherein the base station comprises:
• one or more second processors;
• and
• second memory storing second instructions that, when executed by the one or more second processors, cause the base station to:
• send the configuration information for the plurality of resource allocations.
