20170141878 | SYSTEMS AND METHODS FOR SENDING DATA FROM NON-VOLATILE SOLID STATE DEVICES BEFORE ERROR CORRECTION - Methods and systems for performing operations in a communications protocol are provided. A memory controller can retrieve data packets from the memory and send each retrieved data packet to a host, as each data packet is retrieved. The memory controller can retrieve an error correcting code (ECC) packet corresponding to the retrieved data packets and execute an ECC algorithm to identify and correct potential errors in the retrieved plurality of data packets. The memory controller can send any corrected data packets to the host if any of the retrieved data packets had errors and send a completion packet to the host. | 2017-05-18 |
20170141879 | METHOD FOR DYNAMIC AND SELECTIVE FD-DSDF TRANSMISSION OF A DIGITAL SIGNAL FOR A MARC SYSTEM WITH A FULL-DUPLEX RELAY, AND CORRESPONDING PROGRAM PRODUCT AND RELAY DEVICE - Some embodiments relate to a full-duplex relay for a telecommunications system comprising a plurality of sources, the relay, and a destination. The relay comprises a decoder which estimates for each source a code word x | 2017-05-18 |
20170141880 | METHOD AND DEVICE FOR RECEIVING AND TRANSMITTING INFORMATION IN MULTIMEDIA SYSTEM - A method for transmitting, by a transmission entity, a packet in a system, according to an embodiment of the present invention, comprises the steps of: transmitting an automatic repeat request (ARQ) configuration (AC) message including ARQ configuration information; receiving an ARQ feedback (AF) message indicating that one or more packets are lost, the AF message including information on a propagation delay for packets to arrive at a receiving entity; identifying a delivery time of the packets between the receiving entity and the transmitting entity based on the propagation delay included in the AF message; and determining whether to transmit one or more lost packets based on the delivery time. | 2017-05-18 |
20170141881 | Providing Acknowledgement Information by a Wireless Device - In general, to provide acknowledgment information by a first wireless device, the first wireless device sends repeated instances of acknowledgment information in respective first and second frame structures, in response to receipt of first information from a second wireless device. In addition, the first wireless device also sends further acknowledgment information in the second frame structure that is responsive to second information received from the second wireless device. | 2017-05-18 |
20170141882 | DATA ACKNOWLEDGMENT TO MULTIPLE DEVICES - Various systems and methods for transmitting data are described herein. In one example, a method includes detecting a plurality of data frames to be transmitted using a shared communication network and selecting a first and a second data frame from the plurality of data frames based on a deadline for each of the plurality of data frames. The method also includes transmitting, via a shared communication network, the first data frame to a first client device and waiting for a predetermined delay period. Additionally, the method includes detecting a data acknowledgement frame from the first client device and transmitting, via the shared communication network, the second data frame to a second client device, the first data frame and the second data frame to be transmitted sequentially. Furthermore, the method includes transferring control of the shared communication network to an external device. | 2017-05-18 |
20170141883 | WIRELESS COMMUNICATIONS TERMINAL, BASE STATION DEVICE, AND RESOURCE ALLOCATION METHOD - The purpose of the present invention is to avoid ACK/NACK collision in a system in which E-PDCCH control information is transmitted, increase the utilization efficiency of ACK/NACK resources, and suppress unnecessary PUSCH band reduction. A wireless communications terminal having a configuration comprising: a reception unit that receives control signals including ACK/NACK indexes, via an expanded physical downlink control channel; a control unit that determines, on the basis of the ACK/NACK indexes, whether to use a dynamically allocated dynamic ACK/NACK resource or a specified resource specified beforehand, to send downlink data ACK/NACK signals; and a transmission unit that sends the ACK/NACK signals using the dynamic ACK/NACK resource or the specified resource, as determined. | 2017-05-18 |
20170141884 | USER EQUIPMENT, BASE STATION, AND EARLY DECODING METHOD FOR USER EQUIPMENT - A user equipment, a base station, and an early decoding method for the user equipment are provided. The user equipment executes an early decoding method by disabling some specific frame early termination chances in a blind transport format detection decoding trials so as to reduce decoding complexity. The base station retrieves acknowledgement information transmitted from the UE to terminate transmitting a remaining part of a downlink data once the ACK information indicates an ACK response. | 2017-05-18 |
20170141885 | ENABLING HIGHER-ORDER MODULATION IN A CELLULAR NETWORK - A method for using a high order modulation (HoM) mode for communications with a wireless device in a wireless communication network is provided. The method includes receiving downlink channel quality indicator (CQI) information from an uplink transmission of the wireless device and determining a downlink channel quality estimate from the CQI information. When a measurement of the downlink channel quality estimate satisfies the predetermined criteria for a first predetermined number of consecutive uplink transmissions from the wireless device, a downlink transmission mode of the wireless device is switched from a first modulation mode to the HoM mode. | 2017-05-18 |
