Abstract: A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.

Abstract: Systems and methods are provided for enabling H-ARQ communication between a base station and one or more wireless terminals. Methods for enabling incremental redundancy (IR) based H-ARQ, Chase based H-ARQ and Space-Time Code combining (STC) based H-ARQ between devices for down-link and up-link direction transmissions are provided in the form of an information element (IE) for use with a Normal MAP convention as currently accepted in the draft version standard of IEEE 802.16. In addition, embodiments of the invention provide a resource management scheme to protect a network from abuse of resources from a wireless terminal not registered with the network. Components of the down-link and up-link mapping components of a data frame transmitted from the base station to one or more wireless terminals included messages that are readable by all wireless terminals as well as some messages that are encrypted and only readable by wireless terminals that are authenticated as being registered with the network.

Abstract: Methods, base stations and access terminals for uplink signaling are provided. Resource request channel characteristics such as location in time-frequency, sequence, time slot, are assigned to each access terminal to distinguish their resource requests from the resource requests of other access terminals. Access terminals make requests using a resource request on a resource request channel having the assigned characteristics. The base station can then determine which access terminal transmitted the resource request based on the resource request channel characteristics of the resource request channel upon which the resource request was received. The base station then transmits a response to the request which may for example be a new resource allocation, a default allocation or a renewal of a previous allocation.

Abstract: Systems and methods for closed loop MIMO (multiple input and multiple output) wireless communication are provided. Various transmit formats including spatial multiplexing and STTD are defined in which vector or matrix weighting is employed using information fed back from receivers. The feedback information may include channel matrix or SVD-based feedback.

Abstract: Transmission of uplink control message for a wireless system. The uplink control message may be encoded according to one of multiple possible schemes. The choice of encoding scheme may be made based on the control message size and/or based on the available transmission resources and/or based on the detection scheme used on the receiving end. A modulation scheme may also be selected based on such factors. CDM may be used for certain control messages. Block code encoding, such as Reed-Muller encoding may be used for certain control messages. Different transmission resources may be allocated for different control message uses. The encoding specifics may be selected to obtain a certain hamming distance and/or size of the encoded message or based on other factors.

Abstract: The present invention facilitates handoffs for a mobile terminal in a wireless access network that is capable of supporting different types of handoffs. The different handoff types may include soft handoffs and fast base station switching (FBSS). In operation, context information associated with supporting wireless communications between the wireless access network and the mobile terminal are determined. Based on whether the context information is shared between base stations involved in the handoff or transferred from one base station to another of the base stations involved in the handoff, a particular handoff type is selected from the different handoff types that are available. Selecting the specific type of handoff to use may also be based on the level of context information that is available, the actual content of the context information, application preferences, channel conditions, base station or mobile terminal capabilities, or any combination thereof.

Abstract: A channel descriptor management message is transmitted on a broadcast connection to a mobile terminal. The channel descriptor management message provides a format for a frame. The frame includes a resource space. The channel descriptor management message defines a plurality of channels within the resource space and allocates at least one of the channels to a plurality of users. Subsequent resource allocation messages may refer to a location within a channel rather than a location within the entire resource space.
