Search space design and use

Abstract:

Methods, systems, and devices for wireless communication are described. A network access device may select a search space configuration for transmission of group(s) of one or more control channel elements (CCEs) to convey a downlink control information (DCI) message. The search space configuration may include a cross-coreset configuration, such as a cross-control channel subband configuration, a cross-symbol configuration, and/or a cross-beam configuration. The network access device may transmit the DCI message according to the selected search space configuration. A user equipment (UE) may monitor, based on the search space configuration, the group(s) of one or more CCEs to detect DCI messages. The UE may detect a DCI message for it and decode the DCI message based on the monitoring. Numerous other aspects are provided.
