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 (505) and a center-band (510). Narrow band radio resources (700) are assigned to a portion of the bandwidth that is at least partially within the edge-band (505).

摘要： The present invention provides a method for using uplink reference signals for access grant requests. The method includes determining at the base station that at least one mobile unit is requesting access to at least one uplink channel based on information indicative of a change in a masking sequence applied to at least one reference signal. Another embodiment of the present invention includes providing by a mobile station a first reference signal modulated by a first masking sequence to indicate a request for access to at least one uplink channel.

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.
摘要翻译：一种通信的示例性方法包括：在物理上行链路控制信道（PUCCH）中将控制信令复用到物理上行链路共享信道（PUSCH）上，通过使用PUCCH信息在PUCCH资源块的至少一个资源块内均匀分布PUCCH信息 PUSCH数据。一个例子包括在PUCCH上使用第一恒定幅度零自相关序列（CAZAC）索引，用于一起传送CQI和ACK信息，并且使用第二不同的CAZAC序列索引来单独地传送CQI信息或与NAK信息或DTX通信。所使用的索引提供ACK信息是否通信的指示。所使用的索引还提供隐含的DTX检测，无需额外的处理。

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： A method and an apparatus for scheduling transmissions of a plurality of cells in a wireless communications system including one or more base stations is provided. The method comprises providing a set of virtual channels to enable an intra-cell transmission orthogonal to another transmission within each cell of the plurality of cells and inter-cell transmissions orthogonal to other transmissions across a cluster of cells associated with the one or more base stations. The method further comprises exchanging signaling messages between two or more base stations to coordinate- scheduling of the intra-cell transmission with the inter-cell transmissions for the cluster of cells. For optimizing a parameter associated with scheduling of a plurality of users from a cluster of cells in a wireless communication system, an optimal power level for the parameter of each active user may be searched to maximize an indication of system capacity of the wireless communication system. This enables a coordinated jointly scheduling of the users active in the cluster of cells based on the optimal power levels such that the total interference within the cluster may be minimized to maximize the system throughput/capacity.
