Search space design with overbooking

Abstract:

Improved methods, systems, devices, or apparatuses that support search space design are described. The described techniques enhance the number and utility of applied control channel candidates in the presence of blind decoding and control channel element (CCE) channel estimation limitations. The techniques allocate available blind decodes using a nested mapping scheme over one or more dimensions, based on a prioritization. In some other cases, the number of blind decodes may be allocated, either uniformly, or proportionally, between the plurality of search space set occasions. In some cases, the applied control channel candidates may be determined by dropping control channel candidates along one or more dimensions (e.g., search space set, or search space set occasion), until the blind decoding limitation or CE limitation is satisfied.
