Patent number: 8848679Abstract: To promote network security in a wireless local area network (WLAN), a mobile communication device, which is operable as a mobile wireless access point, may read a WLAN identifier that is known to be used by the WLAN and an indication of a channel on which a wireless access point of the WLAN is known to operate. The device may then monitor the channel for a transmission of the WLAN identifier. The mobile wireless access point may be configured to operate using the selected channel so that the monitoring occurs on the same channel as that on which the mobile wireless access point is operating. The transmission, if detected, may be considered to indicate that the mobile communication device is within the WLAN. Upon detecting the transmission, use of the WLAN identifier by the mobile wireless access point at the mobile communication device may be prevented, e.g. by requiring the mobile wireless access point to use a different WLAN identifier or by disabling the mobile wireless access point.Type: GrantFiled: February 4, 2011Date of Patent: September 30, 2014Assignee: Blackberry LimitedInventor: Kevin John Oerton

Patent number: 8848681Abstract: The exemplary embodiments of this invention generally relate to message header-type notification that, for example, enables the co-existence of a legacy header type with one or more new header types on a same radio link. In one non-limiting, exemplary embodiment, a method includes: determining a type of medium access control (MAC) header to transmit in a MAC transmission; setting a value of a notification field in a resource allocation message based on the determined type of MAC header; and transmitting the resource allocation message. In another non-limiting, exemplary embodiment, a method includes: receiving a resource allocation message having a notification field; and using a value of the notification field to determine a type of medium access control (MAC) header for a MAC transmission.Type: GrantFiled: April 25, 2008Date of Patent: September 30, 2014Assignee: Core Wireless Licensing S.a.r.l.Inventors: Shashikant Maheshwari, Yousuf Saifullah, Nico Van Waes

Patent number: RE45203Abstract: An apparatus and method for transmitting/receiving data in a mobile communication system using multiple antennas are provided. A receiver estimates a fading channel of received data, selects a weight set relative to a maximum data transmission rate from at least one weight set with elements of a plurality of orthogonal weight vectors, and transmits feedback information including the selected weight set and channel-by-channel state information to a transmitter. The transmitter demultiplexes data to be transmitted on a basis of the feedback information into at least one sub-data stream, multiplies each sub-data stream by an associated weight, and transmits the data.Type: GrantFiled: April 26, 2013Date of Patent: October 21, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Jin-Kyu Han, Dae-Gyun Kim, Hwan-Joon Kwon, Dong-Hee Kim, Youn-Sun Kim, Yu-Chul Kim, Cheol Mun

Patent number: RE45236Abstract: A system and method are described for binding together a plurality of wireless data communications channels, whereby an aggregate throughput improvement is realized. A master channel amongst the channels to be bound is compatible with existing standards-based wireless data communications equipment. The master channel serves to perform MAC association and flow control. Aggregate throughput is improved by sending and receiving either multiple sets of separately encoded packets, commonly encoded packets or redundantly encoded packets.Type: GrantFiled: September 13, 2011Date of Patent: November 11, 2014Assignee: QUALCOMM IncorporatedInventors: Paul J.
