The method includes selecting, based on the determined values, a subset k of the N antennas and corresponding baseband information to use to determine output data for the transmission by the user equipment. The method includes determining the output data for the user equipment using the baseband information from the k antennas. Apparatus and computer program products are also disclosed. | 07-04-2013 |
20130172050 | Uplink Grouping and Aperture Apparatus - A method includes selecting a subset k of N accessible antennas to use to process a transmission received at the N antennas and sent by a user equipment, and processing the transmission from the user equipment at least by using baseband information from the k antennas. An apparatus includes one or more processors and one or more memories including computer program code. The one or more memories and the computer program code are configured to, with the one or more processors, cause the apparatus to perform at least the following: selecting a subset k of N accessible antennas to use to process a transmission received at the N antennas and sent by a user equipment; and processing the transmission from the user equipment at least by using baseband information from the k antennas. Additional apparatus, computer programs, and computer program products are disclosed. | 07-04-2013 |
20150201368 | Millimeter Wave Access Architecture with Cluster of Access Points - The exemplary embodiments of the invention provide at least a method and an apparatus to determine a beacon signal for a network node, where the network node is configured to connect with a cluster of access points in a wireless communication network, and where the beacon signal identifies the cluster; and send the beacon signal towards the wireless communication network. Further, the exemplary embodiments of the invention provide at least a method and an apparatus to determine a dominant access point of a cluster of access points based on signaling from at least one access point associated with the cluster of access points; and in response to the determining, direct communications towards the dominant access point of the cluster of access points. | 07-16-2015 |

20090268710 | UPLINK SYNCHRONIZATION WITHOUT PERIODIC RANGING IN A COMMUNICATION SYSTEM - An apparatus and method for uplink synchronization without periodic ranging in a communication system includes a first step ( | 10-29-2009 |
20100296438 | UP-LINK SDMA RECEIVER FOR WiMAX - A method, a system and a receiver device provide timing and frequency correction in a spatial division multiple access (SDMA) system. A timing and frequency correction (TFC) logic/utility obtains a timing error estimate by using pilot symbols on a slot of six tiles. The TFC logic estimates the timing error based on pilot phase differences between unique pairs of tiles when the frequency separation of the tiles is less than a threshold value. When none of the unique pairs of tiles satisfies the threshold value, the TFC logic estimates timing error based on an exhaustive search for each candidate phase error value. The TFC logic performs timing error correction via a timing error estimate based on pilots from the symbols received on each antenna. The TFC logic performs inexplicit frequency error correction according to phase differences based on relative symbol indices. | 11-25-2010 |
20120027111 | METHOD AND APPARATUS FOR MAJOR GROUP SCHEDULING IN A FIXED BEAM COMMUNICATION SYSTEM - An OFDMA communication system is provided that schedules partial usage of subchannels (PUSC) major groups by assigning a beam matrix of a plurality of beam matrices to each major group of multiple PUSC major groups, receiving an uplink signal from each user equipment of multiple users equipment, which uplink signal provides an indication of a channel response associated with the user equipment, determining, for each user equipment of the multiple users equipment and based on the indication of channel quality received from the user equipment, a beam matrix and major group to which to assign the user equipment, and based on the determination of a beam matrix and major group to which to assign each user equipment of the multiple users equipment, assigning two or more users equipment of the multiple users equipment to a same beam matrix and major group during a same time slot. | 02-02-2012 |

20110041472 | AUGER STRIPPER ARRANGEMENT FOR CORN HEAD - A corn head includes plural pairs of first and second laterally spaced rotating stalk rolls each having outer fluting and plural outer arrays of spaced knife members extending along the length of each stalk roll. Corn stalks are directed by rotating pick-up cones each disposed forward of a respective stalk roll into the space between adjacent stalk rolls, where the stalks are directed downwardly through the inter-roll space and are reduced by the cutting action of the rotating knives. Each pick-up cone and its associated stalk roll rotate in opposite directions as do the two stalk rolls. Disposed above and extending along the length of the stalk rolls are a closely spaced upper auger and stripper plate which remove an ear of corn from the stalk and direct the ear to the combine for further processing. A skid plate is disposed adjacent a lower, forward portion of each pick-up cone. | 02-24-2011 |

20110236156 | RETAINING PIN WITH SELF BIASING KEEPING MEANS - A retaining pin with self biasing keeping means has a head and a tubular pin that has a plurality of detent fingers on its end. The detent fingers are formed by slitting and deforming the ends of the pin. The detent fingers are bent to extend beyond the outside diameter of the pin with the forward ends terminating in a diameter smaller than that diameter. As the pin is inserted in a matched opening, the detent fingers compress to allow the pin to penetrate the opening and then return to their original position to retain them therein. To remove the pin, the process is reversed. The instant retaining pin with self biasing keeping means is conducive to modern mass production methods of production such as cold heading. | 09-29-2011 |
