Abstract
In an aspect, a method assists with blind decoding of uplink control signals on a Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH). The method assists in determining the uplink control path in the event a user equipment (UE) misses an uplink grant and blind decoding occurs. It is determined whether an uplink acknowledgement, rank indicator, and/or channel quality indicator are found on a PUSCH. If not, it is determined whether a scheduling request is expected and whether special handling for the scheduling request is indicated. Depending on those determinations, and whether any decoding attempts for uplink signals are successful, either the PUSCH or PUCCH is selected as the uplink control path.
