    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.

    摘要: A receiver in an OFDM based communication system is adapted to perform channel estimation using a received reference signal transmitted from at least one antenna The reference signal is substantially located into at least two OFDM symbols of a transmission time interval comprising of more than two OFDM symbols. A power level of said reference signal is divided into said non-consecutive OFDM symbols in said transmission time interval and adapted to use the reference signal located in a first OFDM symbol in succeeding transmission time intervals in addition to the reference symbols in a current transmission time interval and a preceding transmission time interval.

    摘要: A method of power saving for a wireless transceiver (FIGS. 1 and 2) is disclosed. The transceiver has an active power mode (504) and a reduced power mode (510). The transceiver is operated in the reduced power mode (510) and monitors transmissions from a remote wireless transmitter while in the reduced power mode. The transceiver identifies a transmission from the remote wireless transmitter by a transceiver identity included in the transmission (FIG. 6, UE identification). The transceiver transitions to the active power mode (512) in response to identifying the transmission.

    摘要: Embodiments of the invention provide methods for user equipments to implicitly determine the location for the transmission of uplink control signaling information, that is in response to downlink data packet transmissions, using information that is already available through the downlink control signaling for the respective downlink scheduling assignments. No additional explicit downlink control signaling is required for the transmission of the above uplink control signaling from each user equipment.
