摘要： A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.

摘要： A method is provided for maintaining synchronization between an AT and a base station during an idle period. During the idle period, a reduced number of uplink reference signals for uplink channel quality estimation are sent to the base station by the AT. The uplink reference signals are sent to assist coherent demodulation and uplink channel quality estimation for scheduling. During the uplink idle period, the numbers of uplink reference signals are designed to be reduced in selective coherent bandwidths. The selection of the coherent bandwidth alternates in time and covers the entire spectrum to allow the channel quality estimation through the entire spectrum.

摘要： An exemplary method of communicating includes multiplexing control signaling in a physical uplink control channel (PUCCH) onto a physical uplink shared channel (PUSCH) by puncturing PUSCH data with PUCCH control information using a uniform distribution of the PUCCH information within at least one resource block of the PUSCH data. One example includes using a first constant amplitude zero autocorrelation sequence (CAZAC) index on PUCCH for communicating CQI and ACK information together and using a second, different CAZAC sequence index for communicating CQI information alone or with NAK information or DTX. The used index provides an indication of whether ACK information is communicated. The used index also provides implicit DTX detection without additional processing.
