摘要： Systems and methodologies are described that facilitate compressing headers for relay nodes. In particular, a robust header compression (RoHC) profile can be defined for general packet radio service (GPRS) tunneling protocol (GTP) headers. Upon receiving a packet with one or more GTP headers, an access point or relay node can determine whether the one or more GTP headers are compressible and can apply the RoHC profile to compress the one or more GTP headers. In addition, the packet can include a baseheader encapsulated by the one or more GTP headers, which can also be compressed according to a RoHC profile specific to the baseheader. Moreover, RoHC compressed headers can be decompressed according to the GTP RoHC profile.

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： 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： 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： Methods and apparatuses are provided that facilitate compressing packet headers for communicating among access points. An access point can advertise compression profiles to one or more disparate access points, and the one or more disparate access points can select at least one compression profile for compressing/decompressing packets related to the one or more disparate access points and/or devices communicating therewith. The one or more disparate access points can notify the access point of the selected compression profile, a compression context identifier, and/or static data related to identifying associated packets. In this regard, the access point can compress packets that have the associated static data according to the compression profile and compression context identifier. Similarly, the access point can decompress packets from the one or more disparate access points based on the compression context identifier.

摘要： Systems and methodologies are described that facilitate providing user plane support for internet protocol (IP) relays. Service data units (SDU) received at a radio communication layer can be provided to an upper communication layer, such as a packet data convergence protocol (PDCP) layer, without regard to sequence numbers. The upper communication layer can handle reordering of the received protocol data units. Since communications related to a plurality of devices through one or more IP relays can be mapped over a single bearer, allowing reordering at the upper communication layer can mitigate delay caused where a donor or other upstream access point is delayed in providing a sequential SDU related to one of a plurality of devices downstream. In this regard, SDUs related to other devices can be processed by the upper communication layer while waiting for the sequential SDU.
