Computer generated sequences for downlink and uplink signals in wireless communication systems

摘要

The present disclosure provides a base station transmitter, a user equipment transmitter and methods of operating the base station and user equipment transmitters. In one embodiment, the base station transmitter is for use with a cellular communication system and includes a synchronization unit configured to provide a randomly-generated constant amplitude zero autocorrelation (random-CAZAC) sequence corresponding to a downlink synchronization signal. Additionally, the base station transmitter also includes a transmit unit configured to transmit the downlink synchronization signal using the random-CAZAC sequence. In another embodiment, the user equipment transmitter is for use with a cellular communication system and includes a reference signal unit configured to provide a random-CAZAC sequence for an uplink reference signal corresponding to a one resource block allocation of the user equipment. The user equipment transmitter also includes a transmit unit configured to transmit the uplink reference signal using the random-CAZAC sequence.

1. A user equipment transmitter for use with a cellular communication system, comprising:
a reference signal unit configured to provide a randomly-generated constant amplitude zero autocorrelation (random-CAZAC) sequence for an uplink reference signal corresponding to a one resource block allocation of the user equipment; a transmit unit configured to transmit the uplink reference signal using the random-CAZAC sequence; and wherein a group of random CAZAC sequences provides a mean cross-correlation that is no greater than a corresponding group of cyclic extended or truncated Zadoff-Chu sequences.
