Patent number: 10165597Abstract: In wireless communication networks with distributed medium access control, maximal network throughput is achieved as a compromise between medium contention duration and collision rate. Maximal throughput in self-adapting medium access protocol is achieved by stations maintaining backoff counter BC and freezing counter FC, which define the state in two-dimensional state space. Countdown process is comprised of decrementing BC in idle timeslots, and incrementing FC in busy timeslots. Countdown ends if the value of BC reaches zero, when the station starts to transmit data, or when FC is incremented to be greater than freezing limit FL. In both cases, the station has to randomly select new backoff counter, reset its freezing counter, and continue to count down with these new values of BC and FC.Type: GrantFiled: March 9, 2015Date of Patent: December 25, 2018Assignee: Sveuciliste U Splitu, Fakultet Elektrotehnike, Strojarstva I BrodogradnjeInventors: Ante Kristić, Ivan Ked{hacek over (z)}o, Julije O{hacek over (z)}egović

Patent number: 10135651Abstract: In an example of multi-user wireless communications, an access point may send a downlink frame to a first station. The first station may generate and transmit an uplink frame. A second station in a same or different basic service set coverage area as that of the access point performs a clear channel assessment of a medium associated with the station for transmitting a frame without interrupting a frame exchange between the access point and the first station. The second station receives the downlink frame and the uplink frame of the frame exchange. The second station determines a signal measurement of the uplink frame, and determines a status of the medium based on the signal measurement and the downlink frame. The first station may update or ignore a network allocation vector timer based on the status of the medium. Other methods, apparatus, and computer-readable media are also disclosed.Type: GrantFiled: June 24, 2016Date of Patent: November 20, 2018Assignee: NEWRACOM, INC.Inventor: Ahmad Reza Hedayat

Patent number: 10129859Abstract: Methods, systems, and devices for wireless communication are described. A wireless device such as a user equipment (UE) or a base station may identify a set of resource element groups (REGs) for low latency communication, and each REG may include a portion of a different resource block (RB) of a set of RBs (e.g., a set of non-contiguous RBs). The device may then map an uplink control channel to the selected REGs and communicate on the uplink control channel accordingly. Reference signals may also be transmitted in the same RBs, and the REGs may be mapped around the resources used for reference signals. In some cases, multiple UEs may transmit uplink control data using the same resources using code division multiplexing (CDM) (e.g., if the control payload is relatively small). In other cases, multiple UEs may be frequency division multiplexed (FDM).Type: GrantFiled: June 23, 2016Date of Patent: November 13, 2018Assignee: QUALCOMM IncorporatedInventors: Wanshi Chen, Peter Gaal, Shimman Arvind Patel, Hao Xu, Juan Montojo, Aleksandar Damnjanovic

Patent number: 10075974Abstract: A wireless communication base station device, terminal device, and method have reduced signaling while maintaining high scheduling gain. A judgment unit pre-stores a correspondence between the number of code words and the number of dusters to reduce the maximum value for the number of dusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality, and the maximum value for the number of clusters that is output by the judgment unit, a scheduling unit schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.Type: GrantFiled: September 7, 2017Date of Patent: September 11, 2018Assignee: Sun Patent TrustInventors: Yoshihiko Ogawa, Akihiko Nishio, Daichi Imamura, Seigo Nakao, Masayuki Hoshino, Takashi Iwai, Sadaki Futagi
