Patent number: 9088413Abstract: Apparatuses and methods are provided for generating a plurality of redundancy versions using various rate matching algorithms. In some embodiments, a rate matcher is provided that allocates systematic and parity bits to the redundancy versions in a manner that allows all of these bits to be transmitted in at least one redundancy version. In some embodiments, the rate matcher uses a first puncturing algorithm to generate both a first redundancy version and a third redundancy version, but allocates a different proportion of the systematic bits to these redundancy versions. In these embodiments, the second redundancy version may include only bits that were not transmitted in the first redundancy version.Type: GrantFiled: March 14, 2013Date of Patent: July 21, 2015Assignee: Marvell International Ltd.Inventors: Paul S. Spencer, Amir Winstok

Patent number: 8699316Abstract: Systems and methods are provided for transmitting and receiving an uplink state flag (USF) in a cellular network. A base station may transmit the USF to plurality of mobile stations that share the same frequency channel, and each mobile station can use the USF to determine whether that mobile station can transmit data in an upcoming uplink time period. The base station can encode the USF bits into a plurality of encoded USF symbols, where the encoded USF symbols may be selected from corner signal points in a QAM signal constellation set or from signal points adjacent to the corners of a QAM signal constellation set. The base station can interleave the encoded USF symbols and modulate the encoded USF symbols for transmission using the signal constellation set. A mobile station that can communication with the base station can include a corresponding receiver, de-interleaver, and decoder.Type: GrantFiled: March 21, 2008Date of Patent: April 15, 2014Assignee: Marvell World Trade Ltd.Inventor: Paul S.

Patent number: 8380229Abstract: Apparatus and methods for reducing the amount of time a mobile wireless device needs to be in a wake mode in order to determine whether a particular paging message is or is not directed to the mobile wireless device. The method includes: receiving, by a mobile device of a wireless network, a first paging message; processing, by the mobile device, a portion of the first paging message including comparing the processed portion of the first paging message with a processed portion of a second paging message previously received by the mobile device; and determining, by the mobile device, whether to process other portions of the first paging message based at least in part on the comparison.Type: GrantFiled: December 2, 2011Date of Patent: February 19, 2013Assignee: Marvell International Ltd.Inventor: Paul S.

Patent number: 8290077Abstract: A method for communication includes defining a signal constellation including multiple constellation points in a signal space, such that each constellation point corresponds to a signal representing a respective combination of values of at least three bits, wherein three or more subsets of the bits in each of the constellation points are respectively allocated to three or more data streams. A sequence of signals is received, each signal selected from the signal constellation. The received sequence of the signals is demodulated, and one of the three or more data streams is reconstructed based on the demodulated signals.Type: GrantFiled: February 9, 2009Date of Patent: October 16, 2012Assignee: Marvell International Ltd.Inventors: David Ben-Eli, Tomer Goshen, Yona Perets, Paul S.

Patent number: 8266488Abstract: A transceiver includes a receiver that receives and demodulates a first encoded block of data. The first encoded block of data includes a first redundancy version that corresponds to a first payload portion and a first header portion. The first encoded block of data is received from a communication device that is remote from the transceiver and that is in a cellular telecommunication network. A transmitter transmits an acknowledgement/negative acknowledgement (ACK/NACK) signal that includes a dedicated decoding status indicator for the header portion.Type: GrantFiled: March 26, 2008Date of Patent: September 11, 2012Assignee: Marvell Israel (MIL) Ltd.Inventor: Paul S.

Publication number: 20110044299Abstract: A method includes assigning a communication channel for simultaneous transmission to at least first and second mobile communication terminals using a Time-Division Multiplexing (TDM) communication protocol. Upon determining that data is to be transmitted over the communication channel to both the first and the second mobile communication terminals, the data is transmitted at a first power level that is defined for transmission to the first mobile communication terminal as part of the simultaneous transmission. Upon determining that the data is to be transmitted over the communication channel only to the first mobile communication terminal, the data is transmitted at a second power level that is defined for transmission only to the first mobile communication terminal and is lower than the first power level.Type: ApplicationFiled: August 24, 2010Publication date: February 24, 2011Inventors: Paul S.

Patent number: 7646748Abstract: A communications terminal using interleaving may be awakened at certain times. The paging message determines whether the terminal will remain awake or it can return to sleep. The amount of time that the communications terminal is awakened may be reduced by determining whether it is necessary to demodulate all of the available time slots. In many cases, it may be possible, based on the environment in which terminal finds itself and the quality of the signals it receives, to obtain the necessary information without demodulating symbols from all the time slots in which symbols of the message are transmitted. As a result the period to receive the paging message may be reduced and the power consumption may likewise be reduced.Type: GrantFiled: January 28, 2008Date of Patent: January 12, 2010Assignee: Marvell International, Ltd.Inventors: Paul S.
