Abstract: Various embodiments of the invention may use bitmaps to communicate channel quality index (CQI) information for multiple sub-channels in an orthogonal frequency division multiple access (OFDMA) wireless communications network. A base station may use bitmaps to report on whether the CQI information for each sub-channel has been under-reported or over-reported. A mobile station may use bitmaps to consolidate CQI information for multiple sub-channels into a single CQI set of parameters.

Abstract: Methods and apparatus for allocating Walsh codes to support wireless connections over fundicated and supplemental channels are disclosed. In an exemplary embodiment, a Walsh code for an incoming call is selected from a first group of Walsh spaces if any of those Walsh spaces is capable of supporting the incoming call, and selecting a Walsh code from a second group otherwise. If the Walsh space from which the Walsh code is selected is from the second group, it is marked with a time stamp. The disclosed techniques reduce fragmentation in the overall Walsh space caused by random connection and disconnection from the wireless network.

Abstract: Briefly, in accordance with one or more embodiments, a MAP may be used by a base station to allocate network users for one or more users in a wireless network using persistent scheduling. In the event one or more of the users does not successfully receive a MAP transmitted by the base station, the user may stop transmitting and/or receiving in order to minimize and/or avoid collision with transmissions from other users. The affected user may transmit an indication of the error in receiving the MAP to the base station, wherein the base station may retransmit the previously transmitted MAP to the affected user that did not successfully receive the MAP from the origination transmission.

Abstract translation: 简而言之，根据一个或多个实施例，基站可以使用MAP来使用持续调度来分配无线网络中的一个或多个用户的网络用户。 在一个或多个用户没有成功地接收到由基站发送的MAP的情况下，用户可以停止发送和/或接收，以便最小化和/或避免与来自其他用户的传输的冲突。 受影响的用户可以向基站发送接收MAP中的错误的指示，其中基站可以将先前发送的MAP重传到没有成功接收MAP的受影响的用户从发起传输。

Abstract: Briefly, in accordance with one or more embodiments, HARQ retransmissions may be persistently scheduled so as to efficiently allocate network without requiring the HARQ retransmissions to be scheduled for every frame or nearly every frame. Furthermore, grouping of users may occur using a bitmap for the HARQ retransmissions using the same bitmap as used for scheduling of the original packet transmission or using a separate bitmap for the HARQ retransmissions. In the event one or more scheduled HARQ retransmissions are not needed, the base station is capable of reallocating the previously scheduled resources.

Abstract translation: 简而言之，根据一个或多个实施例，可以持续地调度HARQ重传，以便有效地分配网络，而不需要针对每个帧或几乎每个帧调度HARQ重传。 此外，使用与用于原始分组传输的调度相同的位图使用用于HARQ重传的位图的用户分组，或者使用用于HARQ重传的单独的位图。 在不需要一个或多个调度的HARQ重传的情况下，基站能够重新分配先前调度的资源。

Abstract: A radio base station performs reverse link rate control in a wireless communication network by “stealing” bits on a forward common power control channel. The forward common power control channel is divided into a plurality of frames, with each frame including a plurality of power control groups and each power control group including a plurality of power control slots. The radio base station may dynamically select power control slots depending on user demand to be used for reverse link rate control.

Abstract: An apparatus and method provide MAC logic enabling the use of two or more reverse link rate controls at the same time in one or more sectors of a radio base station. That enables the base station to control reverse link loading via reverse link rate control, while assigning mobile stations to the type of reverse link rate control best suited to their needs. For example, the base station MAC logic may implement both a common rate controller that generates per-sector rate control commands, and a dedicated rate controller that generates per-user rate control commands and assign mobile stations having relatively lax reverse link service needs to the common rate controller, while assigning mobile stations having more demanding reverse link service requirements to the dedicated rate control. More than two rate controls can be implemented, and exemplary choices include per-user, per-sector, per-group, and scheduled rate control in any combination.

Abstract: A mobile communication network comprises a plurality of access nodes, wherein each access node allocates mobile station identifiers to mobile stations from an assigned group of mobile station identifiers. The mobile station identifiers in each group have a common property that identifies the corresponding access node. The mobile station identifier may be used, for example, to locate session information for a mobile station when a mobile station moves between access nodes.
