摘要： Embodiments of a system and method for wireless communication are provided. In certain embodiments, a base station provides a first zone using a first version of the communication standard and a second zone using a second version of the communication standard. In certain embodiments, the base station determines whether a mobile station communicating with the base station in the first zone can support the second version of the communication standard used in the second zone. When the mobile station can support the second version of the communication standard, the base station can send a command to switch the mobile station to the second zone.

摘要： 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.

摘要： A system and method for forming a relay data path architecture in a wireless network is disclosed. The method comprises forming a separate layer-three data link in a wireless network between a relay station, a base station and an access service network gateway (ASN-GW). Each separate layer-three data link is mapped from the ASN-GW to a next element in the wireless network to form a data path from the ASN-GW to the relay station. Data packets can be sent between a mobile station and the ASN-GW through each layer-three data link using a tunneling protocol such that each layer-three data link forms a separate tunnel.

摘要： 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.
