  • Patent number: 8306581
    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.

  • Patent number: 8175022
    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.

  • Publication number: 20120011569
    Abstract: A system to protect MAC control messages is presented. In one embodiment, the system comprises a processor, a memory coupled to the processor, and a communication device coupled to the processor to communicate wirelessly over multiple sub-channels in an orthogonal frequency division multiple access (OFDMA) wireless network. The communication device is operable to determine that a MAC control message is protected if an indicator within the MAC control message is set. The communication device validates, if the indicator is set, integrity of the MAC control message in conjunction with a CMAC (cipher-message authentication code) tuple concatenated with the MAC control message.

  • Patent number: 8031649
    Abstract: Embodiments of systems and methods for arranging data units in a downlink burst transmission are generally described herein. Other embodiments may be described and claimed. In some embodiments a group of data units are arranged by associated identifiers. These identifiers may also be associated with certain subscriber stations. Once arranged, the data units may be transmitted in a downlink burst and received by a subscriber station. The subscriber station may determine the arrangement of the data units to decode until a cutoff value is determined and passed.

  • Publication number: 20110122833
    Abstract: Embodiments of a mobile station and a method performed by a base station for transmitting a paging message to an idle-mode mobile station are disclosed herein. In some embodiments, a multicarrier paging information (MC-PAG-Info) message is transmitted to indicate a time-slot and paging carrier for a subsequent transmission of a paging message to an idle-mode mobile station. The idle-mode mobile station may monitor the indicated paging carrier during the indicated time-slot of a paging listening interval for receipt of a paging message directed to the idle-mode mobile station. In some embodiments, the indicated time-slot and the paging carrier are determined by the idle-mode mobile station using a device identifier of the idle-mode mobile station and hash modulo parameters provided within the paging information message.

  • Publication number: 20110110343
    Abstract: A preemption system enables successful transmission of multiple service data units (SDUs) across a wireless interface. The preemption system addresses out-of-order transmissions of fragments of SDUs, such that the receiver is able to process each successfully. The preemption system enables a higher-priority SDU to simultaneously be transmitted with a lower-priority SDU, so that delays in processing the lower-priority SDU does not negatively affect processing of the higher-priority SDU. The preemption system also addresses non-automatic repeat request medium access controller (non-ARQ MAC) connections that only use hybrid automatic repeat request (HARQ), in which the HARQ transmission may cause out-of-order delivery of SDU fragments.

  • Publication number: 20110096737
    Abstract: Embodiments of the present disclosure describe methods, apparatus, and system configurations for coverage loss recovery in a wireless communication network. A method includes receiving, by a base station of a wireless communication network, a message from a mobile station that includes an indication that the mobile station is in coverage loss recovery, and a mobile station identifier to identify the mobile station. The method further includes determining whether a static context and/or a dynamic context associated with the mobile station identifier is stored at a previous-serving base station of the mobile station and transmitting a message to the mobile station to indicate which re-entry actions are to be performed to facilitate re-entry of the mobile station to the wireless communication network. Other embodiments may be described and/or claimed.
