In this regard a method is introduced comprising determining a total number of allowable continuous logical resource unit (LRU) allocations for a bandwidth, removing allowable allocations to generate a set of allocations that can be indexed with fewer bits than the total number of allowable allocations, and storing an index of the set of allocations in a memory. Other embodiments are also disclosed and claimed.

摘要： A communication apparatus (CA) such as a mobile node/station (MN), a base station (BS), or a radio station (RS) may support determination of HARQ timing. The CA may generate at least in part one or more generalized frames such as a frequency division duplex (FDD) frame or a time division duplex (TDD) frame. The generalized FDD and TDD frames may include support to determine the HARQ timing considering various factors, which may affect the HARQ timing. The FDD and TDD frames may include information corresponding to various factors to determine the HARQ timing considering factors such as DL/UL ratio, number of sub-frames per frame, variable transmission time interval (TTI), relay zones, legacy IEEE® 802.16e zones, and availability of ACKCH.
摘要翻译：诸如移动节点/站（MN），基站（BS）或无线电站（RS）的通信设备（CA）可以支持HARQ定时的确定。 CA可以至少部分地生成一个或多个广义帧，例如频分双工（FDD）帧或时分双工（TDD）帧。广义FDD和TDD帧可以包括支持以考虑可能影响HARQ定时的各种因素来确定HARQ定时。 FDD和TDD帧可以包括对应于各种因素的信息，以考虑诸如DL / UL比，每帧子帧数，可变传输时间间隔（TTI），中继区，传统IEEE 802.16e 区域和ACKCH的可用性。

摘要： In a wireless network, simultaneous support of distributed and contiguous sub-carrier allocation may be accomplished in the same sub-frame or time zone. Techniques are described herein that can be used to allocate distributed and/or contiguous basic (physical) resource blocks to users by specifying a codebook index and parent node. Techniques are described herein that can be used to flexibly set a number of sub-channels over which a subscriber station indicates a channel quality indicator to a base station. Sub-channels may be represented as nodes and may be grouped to include a parent node and child nodes. By specifying a code book to use and a parent node, the channel quality indicator of the parent and children nodes can be indicated.
