摘要： An apparatus and method for establishing a relay transition time in a network node in a wireless communication system comprising comparing a network node transmit/receive (TX/RX) switch time to a switch threshold; and using a fraction of the cyclic prefix (CP) as a guard period if the network node TX/RX switch time is less than or equal to the switch threshold, or using a sounding reference signal (SRS) configured channel to blank out a last symbol if the network node TX/RX switch time is greater than the switch threshold.

摘要： A method for self synchronization of a first base station is described. Synchronization information is received from a second base station. The first base station then synchronizes with the second base station using the received synchronization information. Synchronization information may be received from one or more base stations. The second base station may be part of the one or more base stations. A stratum may be determined for each of the one or more base stations. The synchronization information may include a stratum. The second base station may be selected as a synchronizing base station. The second base station may have the lowest stratum.

摘要： Access control for an access point (e.g., a cell of the access point) may be based on an access mode associated with the access point. For example, depending on the access mode, access control may involve performing a membership check for the access point. Such a membership check may be performed at a network entity, a source access point, or some other suitable location in a network. In some aspects, access control may involve performing a membership check for an access point in conjunction with a context fetch procedure. Such a procedure may be performed, for example, when an access terminal arrives at the access point after experiencing RLF at another access point.

摘要翻译： 接入点（例如接入点的小区）的接入控制可以基于与接入点相关联的接入模式。 例如，根据访问模式，访问控制可以包括执行接入点的成员资格检查。 这样的成员资格检查可以在网络实体，源接入点或网络中的某个其他合适的位置执行。 在一些方面，访问控制可以包括结合上下文获取过程执行接入点的成员资格检查。 这样的过程可以例如在接入终端在另一接入点经历RLF之后到达接入点时执行。

摘要： A method and apparatus for generating a cryptosync is disclosed that generates a cryptosync with the desired variability without the overhead in complexity and size of prior cryptosyncs. The cryptosync is generated from a combination of fields including fields relating to the segmentation and reassembly of the data packets at a transmitting terminal and a receiving terminal. The resultant cryptosync does not repeat during the use of a particular security key.

摘要： Automated PilotPN code conflict resolution using an access point with the assistance of one or more access terminals is disclosed. An exemplary method includes determining a set of access points, as well as determining a set of PilotPN codes used by the set of access points. Detection is then made concerning whether at least two access points of the set of access points have conflicting PilotPN codes. A first PilotPN code is allocated to one of the at least two access points having conflicting PilotPN codes. Additionally, one or more other PilotPN codes, which are distinct from the first PilotPN code, are allocating to remaining access points of the at least two access points having conflicting PilotPN codes. Corresponding apparatus and other exemplary methods are also disclosed.

摘要： A route protocol is established whereby a mobile device can communicate to a multitude of (receiving) base stations though a tunnel created through a serving base station. A message that includes a Route Creation Header can be transmitted by the mobile device to create the tunnel. The Route Creation Header is reviewed by the receiving base station while the mobile device is in a Waiting-To-Open State. Various errors might occur with respect to the Route Creation Header. These errors can be conveyed to the mobile device by base station by setting one or more error code fields. Once the errors are resolved, another attempt to create a tunnel with base station can be made, if desired.

摘要： Methods, apparatus, systems and computer program products are defined that provide for in-order deliver of data packets during hand-off. The aspects provide for in-order delivery at Forward Link Serving eBS/Data Attachment Point (FLSE/DAP) switch and Reverse Link Serving eBS/Data Attachment Point (RLSE/DAP) switch. As such, present aspects provide for significant improvement in the throughput of applications, such as applications relying on Transmission Control Protocol (TCP), during handoff, in such networks as Ultra Mobile Broadband (UMB) and the like.
