摘要： Wireless terminals and base stations support multiple modes of dedicated control channel operation wherein wireless terminals are allocated different amounts of dedicated uplink resources for reporting control information. A set of dedicated control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of dedicated control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the dedicated control channel segments associated with a single logical tone. In split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the dedicated control channel segments. Logical dedicated control channel tones can be dynamically reallocated for full-tone mode use or split tone mode use.

摘要： A base station uses a common link layer controller for multiple physical attachment points to facilitate concurrent wireless connections between different sector physical attachment points and a wireless terminal using the same link layer link. A wireless terminal maintains multiple simultaneous wireless connections for the same link layer link. A packet of user data is fragmented into a plurality of grouping of MAC frames, thus a packet portion can be communicated over a connection. A single packet is sometimes communicated with different portions conveyed over different wireless connections. Automatic repeat request, using the common link layer controller, allows for retransmission of a packet portion over a different connection than it was initially transmitted over. A wireless terminal sends connection request messages including lists of link layer identifiers associated with the wireless terminal. A base station responds with an indication of whether logical link state was already present.

摘要： Techniques for efficiently sending reports in a wireless communication system are described. Reports may be sent repetitively in accordance with a reporting format. A terminal receives an assignment of a control channel used to send reports and determines a reporting format to use based on the assignment. The reporting format indicates a specific sequence of reports sent in specific locations of a control channel frame. The terminal generates a set of reports for each reporting interval and arranges the set of reports in accordance with the reporting format. The terminal repetitively sends a plurality of sets of reports in a plurality of reporting intervals. Reports may also be sent adaptively based on operating conditions. An appropriate reporting format may be selected based on the operating conditions of the terminal, which may be characterized by environment (e.g., mobility), capabilities, QoS, and/or other factors.

摘要： An uplink dedicated control channel reporting structure includes a plurality of different bit size reports, e.g. 1 bit, 3 bit and 4 bit reports, for reporting a wireless terminal's backlog information of uplink traffic request group queues. Smaller bit size reports are transmitted more frequently than larger reports. A 1 bit request report indicates whether or not there are any MAC frames of information to be communicated in a set of two request group queues. A 3 bit request report indicates an amount of backlog information corresponding to a first set of request group queues and a second set of request group queues. A 4 bit request report indicates an amount of backlog information corresponding to a set of request group queues. The 4 bit request report is capable of reporting information on any of a plurality of uplink traffic channel request group queues being maintained by the wireless terminal.

摘要： Systems and methodologies are described that facilitate generating and/or analyzing downlink transmission units in OFDM TDD environments. Strip OFDM symbols may be selectively inserted within downlink transmission units; for example, the position of strip OFDM symbols may vary from cell to cell. Further, the position may be a function of a characteristic of a cell (e.g., cell identifier) and/or an expected drift. Moreover, a strip OFDM symbol may be interjected at a location in a downlink transmission unit so as to mitigate alignment with disparate strip OFDM symbols in downlink transmission units associated with differing cells.

摘要： First and second transmitters transmit signals communicating the same information, e.g., program segment, but at different times. Different carriers may, but need not be, used by the different transmitters. If a wireless terminal can not recover broadcast segment information from one carrier, the wireless terminal can switch to another transmitter and recover the information, e.g., on another carrier, since the broadcasts are intentionally offset in time. In some embodiments, the timing is offset such that a single channel receiver is able to recover signals corresponding to the same program segment from two sources, and perform a decoding and information recovery using input from both sources, where recovery using input from a single source is not possible. Symbol level timing synchronization of base stations is not required thereby allowing for simpler implementations and/or lower overhead, as compared to systems which require base stations to be synchronized to the symbol timing level.
摘要翻译：第一和第二发射机发送传送相同信息的信号，例如程序段，但是在不同的时间。不同的载波可以但不一定被不同的发射机使用。如果无线终端无法从一个载波恢复广播段信息，则无线终端可以切换到另一个发射机，并且例如在另一载波上恢复信息，因为广播被有意地及时地偏移。在一些实施例中，定时被偏移，使得单个信道接收机能够从两个源恢复对应于相同节目段的信号，并且使用来自两个源的输入执行解码和信息恢复，其中使用来自单个源的输入进行恢复不可能。与要求基站与符号定时电平同步的系统相比，不需要基站的符号电平定时同步，从而允许更简单的实现和/或较低的开销。
