发明名称 SENDING PILOTS ON SECONDARY CHANNELS FOR IMPROVED ACQUISITION AND HANDOFF IN CELLULAR COMMUNICATION
摘要 Systems and methodologies are described that facilitate enhancing acquisition and handoff in a wireless network deployment by leveraging primary pilots and secondary pilots. The deployment can support more than one frequency band for operation, yet a mobile device can receive signals on one frequency band at a given time. Thus, a base station can transmit primary pilot(s) over frequency band(s) associated with operating data channel(s) as well as secondary pilot(s) over frequency band(s) that lack data channel(s) for the base station. Moreover, the base station can convey information that indicates to a mobile device whether each pilot is primary or secondary. Further, the mobile device can employ knowledge of pilot type (e.g., primary or secondary) as well as signal strength to effectuate handoff decisions; thus, disruptions in communication can be mitigated.
