摘要： Embodiments of the present disclosure provide techniques for processing a HARQ data burst and/or a HARQ ACK message in the event a HARQ ACK message falls within a scanning or an unavailable interval of an MS. For certain embodiments, a HARQ ACK message may be postponed if it falls within the scanning or the unavailable interval of the mobile station. For certain embodiments, the HARQ data burst transmission may be postponed if the corresponding HARQ ACK message falls within a scanning or an unavailable interval of the mobile station. For certain embodiments, the HARQ ACK may be transmitted or received even if it falls within the scanning or the unavailable interval of the mobile station. However, the HARQ ACK message may not be processed during the scanning/unavailable interval.
摘要翻译：本公开的实施例提供了在HARQ ACK消息落在MS的扫描或不可用间隔内的情况下用于处理HARQ数据突发和/或HARQ ACK消息的技术。对于某些实施例，如果HARQ ACK消息落在移动台的扫描或不可用间隔内，则可以推迟HARQ ACK消息。对于某些实施例，如果对应的HARQ ACK消息落在移动台的扫描或不可用间隔内，则可以推迟HARQ数据突发传输。对于某些实施例，即使HARQ落在移动站的扫描或不可用间隔内，也可以发送或接收HARQ ACK。然而，在扫描/不可用间隔期间可能不处理HARQ ACK消息。

摘要： Methods and apparatus for allocating, modifying, and terminating a fixed data region (termed “sticky region allocation”) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame are provided. With sticky region allocation, the sticky region may be negotiated during the establishment of a connection between a base station and a user terminal, and a single MAP information element (MAP IE) may inform the user terminal of the location of the sticky region. Then, a user terminal can receive/send data bursts for a certain connection in multiple OFDM/OFDMA frames without needing a MAP IE for locating each burst in subsequent frames. Accordingly, the size of the control overhead, such as the downlink (DL) and uplink (UL) MAP messages, may be reduced. The reduced control overhead may increase the frame resources available for data traffic and thus, may boost the overall efficiency and performance of OFDM/OFDMA wireless systems.
摘要翻译：提供了在正交频分复用（OFDM）或正交频分多址（OFDMA）帧中分配，修改和终止固定数据区（称为“粘性区分配”）的方法和装置。通过粘性区域分配，可以在建立基站和用户终端之间的连接时协商粘性区域，并且单个MAP信息元素（MAP IE）可以向用户终端通知粘性区域的位置。然后，用户终端可以在多个OFDM / OFDMA帧中接收/发送用于某个连接的数据突发，而不需要用于定位后续帧中的每个突发的MAP IE。因此，可以减少诸如下行链路（DL）和上行链路（UL）MAP消息之类的控制开销的大小。降低的控制开销可以增加可用于数据业务的帧资源，并且因此可以提高OFDM / OFDMA无线系统的整体效率和性能。

摘要： A base station and a subscriber station may negotiate paging parameters so that the subscriber station can enter idle mode. After the subscriber station has entered idle mode, the base station may change at least one paging parameter at the base station. The base station may direct the subscriber station to change at least one paging parameter at the subscriber station after the subscriber station has entered idle mode. The subscriber station may change at least one paging parameter at the subscriber station after the subscriber station has entered idle mode.
