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： A method for reducing the peak-to-average ratio in an OFDM communication signal is provided. The method includes defining a constellation having a plurality of symbols, defining a symbol duration for the OFDM communication signal, and defining a plurality of time instants in the symbol duration. A plurality of tones are allocated to a particular communication device, and a discrete signal is constructed in the time domain by mapping symbols from the constellation to the time instants. A continuous signal is generated by applying an interpolation function to the discrete signal such that the continuous signal only includes sinusoids having frequencies which are equal to the allocated tones.

摘要： Wireless terminals and base stations support multiple modes of control channel operation wherein wireless terminals are allocated different amounts of uplink resources for reporting control information. A set of 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 control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the control channel segments associated with a single logical tone. In split tone mode, 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 control channel segments. Logical control channel tones can be dynamically reallocated for full-tone mode use or split tone mode use.

摘要： Methods and apparatus of efficient communication of resource allocation are described. A base station transmits a resource assignment message, e.g., a state transition message, to a wireless terminal including a first part, e.g., a base station assigned wireless terminal On state identifier, identifying a resource being assigned and a second part, e.g., an ON state mask, identifying a portion of the resource allocated to the wireless terminal. The same resource allocation message information also communicates one of a plurality of different modes of commanded On state operation. The resource allocation message structure supports flexible allocation of available resources facilitating a resource to be partitioned differently at different times accommodating current needs. A predetermined recurring channel structure and association of segments with particular mask bits, facilitates allocated control segments to be used unambiguously without the need to include an overhead wireless terminal identifier field with the control report bits being communicated.

摘要： Allocation of a wireless communications system channel resource is managed by utilizing traffic segment allocation. This is realized by partitioning the channel resource into an assignment channel and a traffic channel in a fixed manner. The assignment channel includes assignment segments and the traffic channel includes traffic segments. The traffic segment is the basic traffic channel resource unit used to transport traffic data and has a prescribed finite time interval and bandwidth. Each traffic segment is associated with a so-called assignment segment in a prescribed manner. One or more traffic segments may be associated with a particular assignment segment. A base station broadcasts via an assignment segment which wireless terminal is to use a particular traffic segment. This is realized by transmitting a simply identifier for the particular wireless terminal assigned to the particular traffic segment in the assignment segment. Then, each active wireless terminal monitors all of the received assignment segments to detect any traffic channel assignments. Once a wireless terminal detects its identifier in an assignment segment, it proceeds to receive/transmit the traffic data in the traffic segment associated with the assignment segment including the detected identifier.

摘要翻译： 通过利用业务段分配来管理无线通信系统信道资源的分配。 这是通过以固定的方式将信道资源划分为分配信道和业务信道来实现的。 分配信道包括分配段，业务信道包括业务段。 流量段是用于传输流量数据的基本业务信道资源单元，具有规定的有限时间间隔和带宽。 每个流量段以规定的方式与所谓的分配段相关联。 一个或多个业务段可以与特定分配段相关联。 基站通过无线终端要使用特定业务段的分配段广播。 这通过为分配给分配段中的特定业务段的特定无线终端发送简单的标识符来实现。 然后，每个有源无线终端监视所有接收的分配段以检测任何业务信道分配。 一旦无线终端在分配段中检测到其标识符，它继续接收/发送与包括检测到的标识符的分配段相关联的业务段中的业务数据。

摘要： An unique arrangement including a so-called timing control order and timing control signals is employed to identify whether wireless terminals are reachable within a base station cell coverage area in a wireless communications system. To this end, detection of a particular wireless terminal being alive and well, and within the cell coverage area associated with a base station is effected by the base station transmitting a timing control order in a timing control time slot reserved for the particular wireless terminal. If the particular wireless terminal receives the timing control order, it transmits a prescribed timing control message at a prescribed time. If the base station does not receive the timing control message, it is an indication that communication with the particular wireless terminal has been lost.

摘要： In a wireless communications system, multicast messages are transported to groups of wireless terminals by employing a common control channel to transmit a multicast paging message indicating that multicast traffic data is to be transmitted to a particular group of wireless terminals. In an embodiment of the invention, the essential information transmitted in the common control channel is the identifier of the group of wireless terminals intended to receive the multicast traffic data and the location of a traffic channel on which the multicast traffic is to be transported in a channel resource which may include a representation of bandwidth and time interval. In accordance with an aspect of the invention, the common control channel is associated with a traffic channel in a prescribed fixed manner. Further, the traffic channel used for the purpose of multicast can be the same traffic channel used for the normal point-to-point transmission of traffic data.

摘要： In a unique paging time slot format, each of the allocated paging time slots occurs periodically and is split into several prescribed paging time slots including at least one first type paging time slot having a relatively short duration and at least one second type paging time slot having a longer duration. The at least one first type paging time slots is of relatively short duration and transports an indication whether a particular associated wireless terminal was paged. The second type paging time slot is of longer duration than the first type time slot and transports the entire paging message. The paging time slots are periodically transmitted and intended for at least one particular wireless terminal.
