Interleaved control channel for spatial division multiplexing in higher bands

A method for wireless communication at a network device, comprising:

• transmitting, to a user equipment (UE), a signal identifying a configuration of a plurality of search spaces to monitor for a plurality of downlink control information transmissions, wherein the plurality of search spaces is interleaved over a plurality of transmit beams of the network device, and each downlink control information transmission carries information associated with one or more transmit beams of the plurality of transmit beams;
• performing the plurality of downlink control information transmissions in the plurality of search spaces, wherein each search space of the plurality of search spaces includes at least a portion of each downlink control information transmission of the plurality of downlink control information transmissions and the UE decoding each received downlink control information transmission in the plurality of downlink control information transmissions is based at least in part on the UE monitoring the plurality of search spaces;
• and
• wherein the plurality of downlink control information transmissions comprises an instance of a downlink control information in each downlink control information transmission or the instance of the downlink control information spread across a subset of the plurality of downlink control information transmissions.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a network device, a signal identifying a configuration of a plurality of search spaces to monitor for a plurality of downlink control information transmissions, wherein the plurality of search spaces is interleaved over a plurality of transmit beams of the network device, and each downlink control information transmission carries information associated with one or more transmit beams of the plurality of transmit beams;
• monitor the plurality of search spaces for the plurality of downlink control information transmissions associated with the UE, wherein each search space of the plurality of search spaces includes at least a portion of each downlink control information transmission of the plurality of downlink control information transmissions;
• decode each received downlink control information transmission in the plurality of downlink control information transmissions based at least in part on the monitoring;
• and
• wherein the plurality of downlink control information transmissions comprises an instance of a downlink control information in each downlink control information transmission or the instance of the downlink control information spread across a subset of the plurality of downlink control information transmissions.
