The PDCP layer performs ciphering on data (i.e., PDCP SDU) received from an upper layer, generates an indicator discriminating ciphered data and non-ciphered data (i.e., an ROHC feedback packet directly generated by the PDCP layer), and transmits the same to a lower layer (i.e., MAC layer). A PDCP SN (Sequence Number) is defined as an algorithm for ciphering the data in the PDCP layer to perform ciphering in the PDCP layer. | 2013-12-05 |
20130322465 | DOCSIS Upstream Burst Efficiency Maximization and Support for Jumbo Frames - A method for passing ingress and egress jumbo frames and maximizing the use of frame bursts in a cable modem including, receiving from a client device one or more packets to be transmitted over a communication channel, queuing the one or more packets, determining a maximum size of a burst frame transmitted over the communication channel, adding each of the one or more packets in their entirety to the burst frame until the maximum size of the burst frame is reached, determining whether the burst frame has available space, when space is available, fragmenting a packet of the one or more packets into at least a first and a second fragment packet, wherein the first fragment packet has a size substantially equal to the available space of burst frame, and adding the first fragment packet to the burst frame and transmitting the burst frame during a transmit window. | 2013-12-05 |
20130322466 | TRANSPORT STREAM MULTIPLEXERS AND METHODS FOR PROVIDING PACKETS ON A TRANSPORT STREAM - Examples described include transport stream multiplexers that may not need to search for an appropriate source to use to generate a transport stream packet. Instead, the source to use may be indicated by a position (e.g. an entry) in a memory table, e.g. a metadata array. Methods for placing transport stream packets on a transport stream and initializing the metadata array are also described. | 2013-12-05 |
20130322467 | Wireless Memory Management - Memory management for WiFi Media Access Control (MAC) frames includes dividing a memory into equally-sized smaller chunks; writing a MAC frame that is larger in size than one-chunk size into several chunks; appending special information to each chunk to specify whether the chunk is a starting chunk or an intermediate chunk of the MAC frame or whether the chuck is currently unoccupied at all; linking the chunks carrying the MAC frame; and specifying a task waiting to be performed for the MAC frame. The several chunks may be noncontiguous or contiguous. The memory management technique may further comprise searching the memory for chunks comprising frames waiting for a certain task. The memory management technique may further comprise marking the chunks as empty after the certain task is completed. | 2013-12-05 |
20130322468 | APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING DATA IN COMMUNICATION SYSTEM - An apparatus for transmitting data in a communication system includes: a receiving unit configured to receive reception information of a data packet in a receiver from the receiver; a frame generation unit configured to generate a plurality of frames containing data to transmit to the receiver, in consideration of the reception information; a packet generation unit configured to include the plurality of frames into a payload and generate a data packet; and a transmitting unit configured to transmit the generated data packet to the receiver, wherein the payload includes a mode field containing information on the plurality of frames and the plurality of frames. | 2013-12-05 |
20130322469 | MULTI-CHANNEL CODE-DIVISION MULTIPLEXING IN FRONT-END INTEGRATED CIRCUITS - A code-division multiplexing (CDM) system utilized in multi-channel (MC) front-end integrated circuits to significantly reduce the power consumption of such systems. The CDM system extends data compression advantages to uncorrelated and weakly correlated MC signals through the introduction of a new Multi-Channel Signal Binning and Multiplexing (MCSBM) method and architecture. The method achieves significant reductions in power consumption in comparison to a conventional time-division multiplexing quantizer, while adding only a modest amount of overhead and complexity. Systems and methods permit architects to fabricate MC integrated circuits with ultra low power consumption and small chip area. Another embodiment relates to the system's compressor organizing samples of the input signal in such a way that the downstream analog-to-digital converter quantizes the higher variance samples with a higher resolution compared to the resolution it uses to quantize other samples with lower variance. | 2013-12-05 |
20130322470 | HIGHLY EFFICIENT THULIUM DOPED FIBER LASER - In the method of generating high power light with high efficiency and low thermal loading, the improvement comprising the steps of resonantly pumping a first thulium-doped fiber laser with a second thulium-doped fiber last, said second thulium-doped fiber laser having a shorter wavelength than said first thulium-doped fiber laser. | 2013-12-05 |
20130322471 | Modal Corrector Mirror With Compliant Actuation For Optical Aberrations - A laser resonator is provided that includes a cavity bounded by an end mirror and output coupler, and one or more gain media between the end mirror and output coupler. The laser resonator also includes a modal corrector mirror between the end mirror and output coupler. The modal corrector mirror includes a controllable-profile faceplate including an optically-treated front surface, and an array of static actuators. Each static actuator includes an adjustable element, and a compliant mechanism located between the adjustable element and faceplate. The adjustable element is configured to exert a selectable, localized push-pull force on the faceplate via the compliant mechanism, and the compliant mechanism is configured to scale the respective force. | 2013-12-05 |
