摘要： Techniques are disclosed that provide for femto base stations to become synchronized with other base stations in a wireless network. For instance, a macro base station may instruct a mobile station to engage in a synchronization operation that synchronizes one or more timings (e.g., OFDM timings) of a femto base station with one or more corresponding timings of the macro base station. This may involve the mobile station having timing references of the macro base station. Further, this may involve the mobile station performing scanning operations and/or handover ranging operations with the femto base station. The mobile device may determine timing offsets between the femto BS and the macro BS. These offsets may be sent to the macro base station or to the femto base station. Also, the femto base station may adopt timings employed by the mobile station. The macro base station or a femto base station may direct a femto base station to achieve synchronization either directly with timing adjustment offset, or with a list of already synchronized femto base station as synchronization reference.

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： Techniques are disclosed that involve the indication of neighbor base stations. For instance, a base station may generate and wirelessly transmit a message that indicates a plurality of neighboring base stations. This message may include an indicator having one or more wildcard values. Through the employment of such wildcard values, the indicator may provide information corresponding to the plurality of neighboring base stations. For instance, the indicator may indicate a plurality of base station identifiers (BSIDs). Alternatively, the indicator may indicate a plurality of preamble indices. As a further alternative, the indicator may indicate a plurality of carrier frequencies. Through the employment of such techniques, overhead can be saved without causing ambiguity in mobility management.

摘要： 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.
