Control channel processing limits for asynchronous cells

Abstract:

The described techniques provide for devices (e.g., a base station, a user equipment (UE)) to determine control channel processing limits for control channels for a CA configuration for a plurality of component carriers (CCs) with mixed numerology and synchronicities (e.g., CCs may have different transmission time interval (TTI) durations, subcarrier spacings, or frame timing). The devices may determine control channel processing limits for numerology groups or synchronization groups of the CA configuration based on a UE capability for processing control channels for a number of CCs, which may be allocated proportionally according to number of cells, allocated equally, or allocated using weighting factors assigned to synchronization or numerology groups. A base station may establish a CA configuration or control channel configuration according to the capability, or may ensure that a per-numerology restraint is not exceeded by determining a combined processing parameter.
