Patent number: 11116009Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, some user equipment (UEs) may be configured for sidelink communications using a first radio access technology (RAT) (e.g., via a cellular network) and other wireless devices may be configured for sidelink communications using a second RAT (e.g., via a wireless local area network (WLAN)).

Patent number: 9325368Abstract: A period is defined to execute the sequences (processes) of communication data acquisition, measuring communication quality, communication quality data acquisition, and channel change. Processing is controlled to execute each process within a time limit set for each process and execute all processes in one cycle. This avoids that a delayed sequence influences and delays other sequences and can suppress delays. If processing fails to finish a sequence, it will resume the same sequence in the next cycle. For communication stations sharing timeslots, there are provided offset periods differing in length before the start of carrier sense in the timeslots for these stations. Consequently, even under a condition in which packet collision may occur, the collision of packets can be avoided by detecting a packet sent to another station by carrier sense. Moreover, by controlling sending priority of packets in the send queue of the gateway, sending delay can be avoided.Type: GrantFiled: February 4, 2013Date of Patent: April 26, 2016Assignee: Hitachi, Ltd.Inventors: Yasutaka Serizawa, Takashi Yano, Masayuki Miyazaki, Kenichi Mizugaki

Patent number: 9026126Abstract: Various embodiments relate to using available spectrum for peer to peer communications and for selecting which of several possibly available channels should be used. Various methods and apparatus are well suited to peer to peer networks in which channel usage decisions are made in a decentralized manner. A wireless terminal generates a list of potential available channels to be used for peer to peer communications, e.g., based on FCC information and/or local sensing. Channels are filled in accordance with a predetermined channel ordering. A wireless terminal migrates between the channels in accordance with changes in the number of peer devices using a channel. The network, in a distributed manner, changes the number of channels in use at a location in response to changes in numbers of active peer devices at a location.Type: GrantFiled: June 20, 2013Date of Patent: May 5, 2015Assignee: QUALCOMM IncorporatedInventors: Junyi Li, Saurabha Rangrao Tavildar, Aleksandar Jovicic, Hongseok Kim

Patent number: 9014151Abstract: A method and apparatus for low-rate traffic signal transmission on Optical Transport Networks (OTN). The method includes: defining a frame format of the low-rate traffic optical channel data unit (ODU) signal for bearing the low-rate traffic signal; mapping the low-rate traffic signal to the low-rate traffic optical channel payload unit (OPU) of the low-rate traffic ODU signal, generating overhead bytes and filling the bytes in an overhead section of the low-rate traffic ODU to obtain the low-rate traffic ODU signal; multiplexing low-rate traffic ODU signals to an ODUk signal of which the rate matches the transmission rate rank of the OTN where the signal is transmitted, and transmitting the signal via the OTN. Based on this method, the invention provides an apparatus for the low-rate traffic signal transmission in the OTN as well. With this invention, the low-rate traffic signal transmission in the OTN can be implemented conveniently.Type: GrantFiled: September 22, 2006Date of Patent: April 21, 2015Assignee: Huawei Technologies Co., Ltd.Inventor: Shimin Zou

Patent number: 9002364Abstract: A system, method and computer-readable medium for allocating multiple subscriptions to a single mobile terminal thereby allowing concurrent termination of multiple calls at the mobile terminal are provided. A mobile terminal adapted to terminate multiple concurrent calls is described. In one implementation, a network need not have any configuration data regarding the multi-line capabilities of the mobile terminal. In other implementations, network-centric mechanisms are provided for allowing multiple concurrent calls to be terminated by a mobile terminal. Multiple concurrent calls may be terminated at a mobile terminal on separate carrier frequencies or alternatively may be terminated on a common carrier frequency.Type: GrantFiled: May 22, 2007Date of Patent: April 7, 2015Assignee: Tango Networks, Inc.Inventors: Andrew Silver, Douglas J.
