摘要： Systems and methodologies are described that facilitate compressing headers for relay nodes. In particular, a plurality of internet protocol (IP) headers, tunneling protocol headers, and/or other routing headers in a packet can be compressed to facilitate efficient communications of packets between relay nodes and/or a donor access point. An access point receiving packets to be compressed can provide a disparate access point with a compression context and an uncompressed packet. The disparate access point can generate a decompression context related to subsequent packets having similar header values and can store the decompression context with the context identifier. The access point can subsequently compress received packets having similar header values and communicate the compressed packets with the context identifier to the disparate access point. The disparate access point can apply the previously generated decompression context associated with the context identifier to decompress the packets.
摘要翻译： 描述了便于压缩中继节点的报头的系统和方法。 特别地，可以压缩分组中的多个因特网协议（IP）报头，隧道协议报头和/或其他路由报头，以促进中继节点和/或施主接入点之间的分组的有效通信。 要接收要被压缩的分组的接入点可以提供具有压缩上下文和未压缩分组的不同接入点。 不同的接入点可以生成与具有相似报头值的后续分组相关的解压缩上下文，并且可以将解压缩上下文存储为上下文标识符。 接入点可以随后压缩具有相似报头值的接收分组，并将具有上下文标识符的压缩分组传送到不同的接入点。 不同的接入点可以应用与上下文标识符相关联的先前生成的解压缩上下文来解压缩数据包。

摘要： Systems and methodologies are described that facilitate compressing headers for relay nodes. In particular, a plurality of internet protocol (IP) headers, tunneling protocol headers, and/or other routing headers in a packet can be compressed to facilitate efficient communications of packets between relay nodes and/or a donor access point. A donor or other upstream access point can be provided with a filter mask, bit stream, and filter mask identifier generated by a related relay node for packets having given static header data. Thus, the donor or other upstream access point can apply the filter mask to incoming packet headers, and where a resulting bit stream matches the received bit stream, can replace at least a portion of the packet headers with the filter mask identifier. The relay node can subsequently decompress the packet headers based on the filter mask identifier. Similar functionality can be used for compressing uplink communications.

摘要： Certain embodiments of the present disclosure propose methods for supporting multicarrier in a radio link control (RLC) communication layer. The proposed methods reduce the processing required when scheduling information for each carrier becomes available by generating protocol data units (PDUs) in advance, and storing the PDUs in buffers associated with each carrier.

摘要： A novel group key distribution and management scheme for broadcast message security is provided that allows an access terminal to send a single copy of a broadcast message encrypted with a group key. Access nodes that are members of an active set of access nodes for the access terminal may decrypt and understand the message. The group key is generated and distributed by the access terminal to the access nodes in its active set using temporary unicast keys to secure the group key during distribution. A new group key is provided every time an access node is removed from the active set of access nodes for the access terminal.

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： Systems and methods are disclosed to enable multiple neighbour base stations or access points (APs) preparation for handover robustness. The systems and methods include generating a handover request message at a source base station (BS) for user equipment (UE) if the UE detects at least one neighbour BS. The handover request message may include a handover imminent flag. The handover request message is transmitted to the neighbour BS, wherein if the handover imminent flag indicates that the handover is not imminent, the neighbour BS does not reserve a radio network temporary identifier (RNTI) for the UE.
