摘要： A method for compressing a user datagram protocol (UDP) data packet includes: when receiving an Internet Protocol version 4 (IPv4) UDP data packet, a compressor searching a context of the UDP data packet, if the context does not exist, creating the context of the UDP data packet, taking a value of an IP identifier (IP-ID) field of the UDP data packet as an initial value of a serial number (SN) of the context, and then compressing the UDP data packet according to the context. Also provided are methods and devices for compressing and decompressing a UDP data packet. The methods and devices can effectively improve the compression efficiency, reduce the probability of sending the IR/IRDYN packet, significantly reduce 1 byte transmission, improve the compression efficiency by 50%, and reduce the probability of using an extension header with a high capacity.

摘要： Techniques to increase capacity in a wireless communications system. In an aspect, systematic non-transmission, or “blanking,” of minimal-rate frames transmitted in a communications system is provided. In an exemplary embodiment, eighth rate frames in a cdma2000 voice communications system are systematically substituted with null-rate frames carrying zero traffic bits. Provisions are nevertheless made for the transmission of certain designated as “critical” by, e.g., a vocoder. The receiver detects the presence of null rate or non-null rate transmissions and processes the received frames accordingly, including updating an outer loop power control only in response to non-null rate frames. Further techniques for changing the pilot transmission gating pattern to assist the receiver in detecting null rate frames are provided. In another aspect, early termination of a signal transmission over a wireless communications link is provided. In an exemplary embodiment, a base station (BS) transmits power control groups (PCG's) for a frame over a forward link (FL) to a mobile station (MS) until accurate reception of the frame is acknowledged by the MS over a reverse link (RL), possibly before all PCG's of the frame are received over the FL. Possible ACK signaling methods are defined for channels associated with a cdma2000 wireless communications system. In another exemplary embodiment, techniques for reverse link early termination are also provided.

摘要： Systems and methodologies are described that facilitate compressing multiple headers in wireless communication networks that utilize relay nodes. Relay nodes and/or other access points can insert headers in packets related to routing the packets. The multiple headers can be compressed at a transmitter and decompressed at a receiver to save bandwidth over a radio interface. Recursive compression and/or decompression can be utilized at least in part by recursively calling a compression/decompression engine or context, such that no modification is required of the engine or context. The recursive compression/decompression can compress and/or decompress packet headers until a certain type of header is reached (or a certain type of header is no longer found in the packet), according to a tunnel depth, according to newly defined compression and/or decompress profiles, and/or the like.

摘要： Techniques to transmit data with cyclic delay diversity and pilot staggering are described. For cyclic delay diversity, OFDM symbols having different cyclic delay durations are generated. The cyclic delay durations for the OFDM symbols may be selected to be time varying with respect to the cyclic delay durations for OFDM symbols transmitted by a neighboring base station. An FDM pilot is generated and multiplexed on multiple sets of subbands in different symbol periods. Waveforms for a second radio technology (e.g., W-CDMA) may be generated for data to be transmitted with this radio technology. The OFDM symbols are multiplexed onto time slots used for OFDM, and the waveforms for the second radio technology are multiplexed onto time slots used for this radio technology. One or multiple modulated signals may be generated based on the multiplexed OFDM symbols and waveforms. Each modulated signal is transmitted from a respective antenna.
