Aspects of the present disclosure provide for the transmission of a cell identifier of a serving cell to a user equipment (UE). A Physical Cell Identification Channel (PCICH) is defined for carrying the cell identifier of the serving cell within an uplink-based mobility framework. In some examples, the PCICH may be transmitted in response to a trigger event that requires the user equipment to have knowledge of the cell identifier. For example, the UE may require the cell identifier to demodulate signals received from the serving cell and facilitate transmission and/or reception of user data traffic with the serving cell.
