摘要： Frames of information are communicated between a base station (28) of a radio access network (RAN) and plural types of wireless terminals (30). Frame handlers of the base station and of certain types of wireless terminals (30-2) process differing portions of the frame according to respective differing multiple access technologies. In differing embodiments and implementations, modulation techniques of the differing multiple access technologies can be apportioned to differing portions of the frame in various manners, such as (for example) to differing subframes of a multi- sub-framed frame or to differing burst fields or sections of an uplink (UL) burst.

摘要： Methods and apparatus by which receiving stations or other communication network nodes can receive quick paging code words assigned by transmitting stations to the receiving stations. A receiving station can estimate the characteristics of the channel to the transmitting station based on a downlink-frame's preamble and use correlation to detect the presence of an assigned code word. The receiving station can suppress interference from other transmitting stations in the correlation operation based on the nature of the interference signal. When the receiving station knows an interfering signal from another transmitting station, the receiving station can subtract the interfering signal before carrying out the correlation operation.

摘要： The iterative decoding of blocks may be continued or terminated based on CRC checks. In an example embodiment, one iteration of an iterative decoding process is performed on a block whose information bits are covered by a CRC. The iterative decoding process is stopped if the CRC checks for a predetermined number of consecutive iterations. In another example embodiment, a decoding iteration is performed on a particular sub-block of multiple sub-blocks of a transport block, which includes a single CRC over an entirety of the transport block. The CRC is checked using decoded bits obtained from the decoding iteration on the particular sub-block and decoded bits obtained from previous decoding iterations on other sub-blocks of the multiple sub-blocks. The decoding iteration is then performed on a different sub-block if the CRC does not check. Also, the decoding iterations for the sub-blocks may be terminated if the CRC checks.
摘要翻译：块的迭代解码可以基于CRC检查继续或终止。在示例实施例中，对其信息比特被CRC覆盖的块执行迭代解码过程的一次迭代。如果CRC检查预定数量的连续迭代，则停止迭代解码过程。在另一示例实施例中，在传输块的多个子块中的特定子块上执行解码迭代，该传输块包括整个传输块上的单个CRC。使用从特定子块上的解码迭代获得的解码比特和在多个子块的其他子块上从先前解码迭代获得的解码比特来检查CRC。然后如果CRC不检查，则在不同的子块上执行解码迭代。而且，如果CRC检查，则子块的解码迭代可以被终止。

摘要： A base station in an OFDMA system which determines a modulation and coding scheme to use for a packet of a certain size to be transmitted by a Mobile Station. The base station schedules transmissions by mobile stations and transmits packets. The base station includes a processing unit which determines a number of time-frequency resources required to transmit the packet for a modulation and coding scheme, determines an SlNR based on the number of time-frequency resources used and available power at the mobile station, determines a transmission rate as a ratio of the packet size transmitted to the number of time-frequency resources used, sets a rate to zero if the determined SlNR is lower than a threshold SINR required for the modulation and coding scheme, and selects the modulation and coding scheme with a highest transmission rate. The base station includes a memory storing modulation and coding schemes.

摘要： The present invention provides systems and methods that enable a base station to consume less power. According to an embodiment of the invention, the base station reduces its power consumption by not continuously broadcasting control information. In such an embodiment, a mobile station that seeks access to a network to which the base station provides access does not search for broadcast control information prior to transmitting an access message to the base station, but rather simply transmits on a predetermined access channel an access request message. A base station that receives the access request message may unicast control information to the mobile station.
