Abstract: A method to perform deregistration with context retention is presented. In one embodiment, the method includes storing a context associated with a mobile station in response to a deregistration request from the mobile station. The method includes determining whether or not to accept the deregistration request with context retention and sending a deregistration command message to the mobile station if the deregistration request with context retention is allowed.

Abstract: Some demonstrative embodiments include devices, systems and/or methods of managing power saving mechanisms of wireless communication devices. For example, a wireless communication unit may relay communications between a wireless communication device and a base station, wherein the wireless communication unit is to manage a power-saving mechanism of the wireless communication device by scheduling one or more power-save periods for the wireless communication device, and transmitting to the wireless communication device a power-save message indicating the one or more power-save periods. Other embodiments are described and claimed.

Abstract: A method and apparatus for encoding an identification of a subscriber station and its connections in a data frame for transmission in a wireless communication network comprising at least one base station and at least one subscriber station is disclosed. The method comprises specifying a subscriber station identification in the data frame to identify the one or more subscriber stations for which contents of the data frame are destined and specifying a connection identification in the data frame to identify one or more connections of the one or more identified subscriber stations to which the contents of the data frame belong. The subscriber station identification and the connection identification can be specified in a single stage or in two stages.

Abstract: Briefly, in accordance with one or more embodiments, a subscriber station in sleep mode is capable of sending and/or receiving traffic during sleep mode without violating the delay requirements of best effort traffic. Moreover, a subscriber station is capable of remaining in sleep and may optionally only be awaken in the event there is data to be transmitted from the base station to the subscriber station and/or from the subscriber station to the base station. By implementing an always sleep and need based wake up arrangement, the power consumption of the subscriber station can be reduced.

Abstract: Short user messages can be conveyed in system management signaling for a data or telephony network. In one example, a first control message is sent from a first radio to a second radio, the control message including a data field, the data field containing a short message directed from a user of the first radio to a user of a third radio. In response, a second control message is received in reply to the first control message from the second radio, the second control message including a data field, the data field containing a response to the short message.

Abstract: An embodiment of the present invention provides a method, comprising using short Subscriber Station Identification (short SS ID) to identify idle mode Subscriber Stations in a wireless network. Further, in an embodiment of the present invention the short SS ID is used instead of other methods including systems such as CID in the case of connected mode users and the short SS ID is used instead of its MAC address in the case of idle mode users.

Abstract: Techniques to permit scheduling of mixed radio access technologies. In some cases, a first radio access technology mode of a base station is scheduled during a first time region and a second radio access technology mode of a base station is scheduled during a sleep mode of the first radio access technology mode. In some cases, a first radio access technology mode of a base station is scheduled during a first time region and a second radio access technology mode of a base station is scheduled during an unused portion of the first time region. In some cases, a femto-base station is scheduled to snoop for local mobile stations during a sleep mode. Inactive regions of mobile stations are scheduled during a portion of sleep modes of the radio access technology modes.

Abstract: Techniques are disclosed for achieving efficient paging in a wireless network. In at least one embodiment, paging is performed in a manner that achieves a balance between paging latency and paging signaling overhead.

Abstract: The various inventive embodiments relate to arrangement of information elements (IEs) for persistent and/or dynamic allocations in a wireless broadband network and include optimization techniques to eliminate the repetitive information fields from the downlink (DL)-Persistent-IEs, uplink (UL)-Persistent-IEs, DL-IEs, and UL-IEs. Elimination of repetitive information fields reduces MAP overhead. In addition embodiments relate to methods to use the same hybrid automatic repeat request (HARQ) region to contain persistent as well as non-persistent allocations. The use of the same HARQ region for persistent as well as non-persistent allocations further reduces the MAP overhead as it requires a single header to define the HARQ region instead of the two headers that are required to define two different HARQ regions: one for persistent allocation and the second one for non-persistent allocations.

Abstract: Techniques for efficient transfer of media access control (MAC) structures in a wireless communication system are described. An apparatus may comprise a MAC controller comprising one or more components operative to establish a unidirectional logical link between a base station and a mobile station in either a downlink or uplink direction. The MAC controller may include a service data unit (SDU) scheduler operative to schedule SDUs from different connection queues for communication by a single MAC PDU for a single downlink burst or single uplink burst of a communication frame in the respective downlink or uplink directions. Other embodiments are described and claimed.

Abstract: In an Orthogonal Frequency Division Multiple Access communication system, the location of one- and two-dimensional bursts may be specified by specifying the starting location of the plurality of bursts. The length of a burst may then be determined by subtracting starting locations of successive bursts. In some embodiments, the number of bits needed to specifying the location of bursts may be reduced.

Abstract: The particular frame in a super-frame using orthogonal frequency division multiple access techniques will contain system configuration information in the super-frame header. This super-frame header may be located at a fixed offset from the initial preamble of the frame. In some embodiments, the system configuration information may be located in a broadcast channel section of the super-frame header. In some embodiments, the particular frame may overlap a legacy OFDMA frame in time and in OFDMA sub-channels, so that the two frames share some time and sub-channel resources.
