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： In a communication system in which a gateway entity is linked to a plurality of infrastructure entities which in turn are operable to communicate with an access terminal, the access terminal needs first to establish a data attachment point (DAP) with one of the infrastructure entities. Handoff of the DAP from one infrastructure entity to another infrastructure entity is initiated by the access terminal. The access terminal weighs factors such as the link conditions with the various infrastructure entities, the time since the last DAP handoff, and time duration communicating with the current infrastructure entity before proceeding with the DAP handoff.

摘要： Methods and apparatus for formatting headers for data packets within a communication frame for use in a wireless communication system are presented. Formatting headers includes determining the size of a wireless communication frame, and formatting the payloads and associated headers within the communication frame according to the determined size. This formatting includes placing headers at the beginning of the frame before the data packets corresponding to the headers to optimize processing of the headers at a receiver. Formatting may also include formatting the headers according to a first format within the frame when the determined frame size is below a predetermined size to optimize the size of the headers, and formatting according to a second format within the frame size of the data packet is equal to or greater than the predetermined size to optimize processing for frames having large data packets.

摘要： Certain aspects of the present disclosure provide techniques and apparatus for startup and recovery of a radio link between a relay node and a donor base station. According to certain aspects, a relay node may perform a random access procedure utilizing a random access channel (RACH) to transition between Uu interface operations and Un interface operations. According to certain aspects, the relay node may perform radio link failure (RLF) recovery utilizing RACH procedures for a Un interface. The procedures described herein, according to certain aspects, may utilize a dedicated relay RACH resource and a Relay Physical Downlink Control Channel (R-PDCCH).
