Configuring downlink control information to schedule multiple component carriers

A method for wireless communication, comprising:

• connecting with a user equipment (UE) over a set of component carriers according to a carrier aggregation configuration, the set of component carriers including at least a first component carrier and a second component carrier;
• transmitting, to the UE, configuration information for a search space configured for scheduling multiple component carriers, the configuration information for the search space indicating an association between the search space and the multiple component carriers, the association used for monitoring the search space for scheduling multiple component carriers;
• transmitting downlink control information comprising a carrier indicator field based at least in part on transmitting the configuration information, the downlink control information scheduling a plurality of data transmissions over the first component carrier and the second component carrier, wherein the first component carrier and the second component carrier are indicated from the set of component carriers by the monitored search space, the carrier indicator field, or both;
• and
• transmitting or receiving the plurality of data transmissions over the first component carrier and the second component carrier based at least in part on transmitting the downlink control information.

An apparatus for wireless communication, comprising:

• at least one processor,
• memory coupled to the at least one processor, the memory storing instructions for the at least one processor to cause the apparatus to:
• connect to a network entity over a set of component carriers according to a carrier aggregation configuration, the set of component carriers including at least a first component carrier and a second component carrier;
• receive configuration information for a search space indicating an association between the search space and multiple component carriers;
• monitor a search space configured for scheduling the multiple component carriers based at least in part on the association;
• receive, from the network entity, downlink control information comprising a carrier indicator field based at least in part on the monitoring, the downlink control information scheduling a plurality of data transmissions over two or more component carriers from the set of component carriers;
• determine that the two or more component carriers comprise the first component carrier and the second component carrier based at least in part on the monitored search space, the carrier indicator field, or both;
• and
• transmit or receive the plurality of data transmissions over the first component carrier and the second component carrier based at least in part on the determining.
