Location based coreset configuration for transmitting the physical downlink control channel in 5G wireless communication systems
The disclosed subject matter relates to techniques for determining an appropriate aggregation level for a control channel resource set (CORESET). In one embodiment, a method is provided that comprises determining, by a first device operatively coupled to a processor, an aggregation level for application by a second device to decode candidate downlink control channels associated with a CORESET. The method further comprises transmitting, by the first device, aggregation level information to the second device indicating the aggregation level. As a result of the transmitting, the second device becomes configured to apply the aggregation level in association with attempting to decode the candidate control downlink control channels. In various embodiments, the aggregation level is determined based one or more criteria, including an aggregation level capability of the second device, a location of the second device relative to the first device, and a geometry associated with the second device.
