CONTROL RESOURCE CONFIGURATIONS

Abstract:

Methods, systems, and devices for wireless communications are described to support complexity reduction for a control resource set (CORESET). A low complexity user equipment (UE) may experience reduced performance if a number of resource block (RB) groups in a CORESET is above a given threshold, or if any symbols of a CORESET are multiplexed with any other signal or channel. A base station may configure a CORESET for a low complexity UE to support reduction in complexity of information detection compared with a CORESET configured for other UEs. The configured CORESET may be based on one or more capabilities of a low complexity UE and may include a reduced number of RB groups or may avoid overlapping with any other signal or channel. If a CORESET configured for a low complexity UE is does not support complexity reduction, the UE may suppress decoding search space candidates on the CORESET.
