Patent number: 10432382Abstract: An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.Type: GrantFiled: March 17, 2015Date of Patent: October 1, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Hwan-Joon Kwon, Kyeong-In Jeong, Jin-Kyu Han, Dong-Hee Kim

Patent number: 10028156Abstract: Methods, systems, and devices are described for wireless communications. A device may utilize enhanced roaming techniques to identify a candidate channel for roaming. In one example, a device determines whether a candidate channel is congested by calculating a congestion metric associated with traffic over the shared channel. In some examples, the congestion metric is calculated based at least in part on an amount of energy measured over the candidate. For instance, the calculated congestion metric can be an instantaneous congestion level measured during a CCA. The device may then determine whether to roam to the candidate channel based at least in part on the calculated congestion metric.Type: GrantFiled: November 17, 2015Date of Patent: July 17, 2018Assignee: QUALCOMM IncorporatedInventors: Sandip HomChaudhuri, Xiaolong Huang, Pradeep Kumar Yenganti, Srinivas Katar

Patent number: 10028247Abstract: Managing of paging of a wireless device (120). A first network node of a wireless communication network (100) determines (203; 301) a code rate and/or transmit power for a present paging message based on a location in a sequence of paging messages. The location is associated with the present paging message. The first network node transmits (204; 302) the present paging message targeted for receipt by the wireless device (120). The present paging message commands the wireless device (120) to connect, or at least initiate connection, to the wireless communication network (100). The present paging message is being coded based on the determined code rate and/or being transmitted based on the determined transmit power.Type: GrantFiled: October 9, 2014Date of Patent: July 17, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: David Better, Walter Müller

Patent number: 10021548Abstract: Encoding and decoding schemes at an encoding device/transmitter and decoder device/receiver, respectively, for use in communicating the state of a system. In an example method carried out by an encoding device, state information x(k), which represents the current state of a monitored system, is measured. The encoding device calculates a state update parameter, based on: a message power constraint P; the covariance N of measurement noise associated with the channel over which encoded state information is to be transmitted; and the norm of the signal vector [s(k), x(k)], where s(k) is a stored state information parameter. The encoding device then calculates a message signal z(k)=G(k)*(x(k)?s(k)), which may then be transmitted to a remote decoder device, and calculates an updated version of the stored information s(k+1)=A*(s(k)+F(k)*z(k)). The encoding device replaces the stored state information s(k) with s(k+1).Type: GrantFiled: August 15, 2014Date of Patent: July 10, 2018Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Ather Gattami
