ABSTRACT:
In one non-limiting aspect thereof, the exemplary embodiments of this invention provide a user equipment that includes a data processor; and a wireless transceiver configured to transmit uplink pilot signals during sub-bands and slots, wherein at least three blocks (LB1, LB2and LB3) are reserved for pilot signals. LB1and LB2include in-band pilot signals transmitted using a dedicated pilot code. The wireless transceiver is further configured to transmit LB3using a frequency hopping pattern and pilot code allocation that are based on a slot and a sub-band in which a first LB3is transmitted. Thus, the code and hopping pattern of a scheduled user equipment are resource-specific (defined by an allocated resource), as opposed to being user equipment-specific.
