Apparatus, method, and computer program product providing improved uplink pilot transmission schemes
First Claim
1. A method comprising:
- transmitting uplink pilot signals during sub-bands and slots, wherein at least three blocks (LB1, LB2 and LB3) are reserved for pilot signals, wherein LB1 and LB2 comprise in-band pilot signals transmitted using a dedicated pilot code; and
transmitting LB3 using a frequency hopping pattern and pilot code allocation that are based on a slot and a sub-band in which a first LB3 is transmitted.

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, LB2 and LB3) are reserved for pilot signals. LB1 and LB2 include in-band pilot signals transmitted using a dedicated pilot code. The wireless transceiver is further configured to transmit LB3 using a frequency hopping pattern and pilot code allocation that are based on a slot and a sub-band in which a first LB3 is 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.
