Patent number: 11889532Abstract: Methods and systems may include processes by which the reliability and robustness of a wireless network may be improved. In some implementations, a method may include selecting at least two resource units to be used for communications to a single client device; and transmitting data in duplicate via each of the at least two resource units to the client device such that the client device is able to combine the data from each of the at least two resource units into a single instance of the data. In some implementations, a method may include obtaining notification of one or more ranges of frequencies corresponding to a set of resource units to be avoided in a spectrum of available frequencies, and allocating resource units to a set of client devices that covers the available frequencies while excluding the set of resource units to be avoided.Type: GrantFiled: September 30, 2020Date of Patent: January 30, 2024Assignee: MaxLinear, Inc.Inventors: Abhishek Kumar Agrawal, Imran Latif, Sigurd Schelstraete, Hossein Dehghan

Patent number: 11882589Abstract: Example operations may include initiating wireless transmission of a first data frame of data designated for wireless transmission. The wireless transmission of the first data frame may be via a first wireless signal packet configured to carry the data of the first data frame. The operations include directing termination of the wireless transmission of the first data frame via the first wireless signal packet prior to wireless transmission, via the first wireless signal packet, of all of the data of the first data frame. In addition, the operations include directing, in response to termination of transmission of the first data frame, wireless transmission of a termination signal, the termination signal indicating that transmission of the first data frame via the first wireless signal packet terminated prior to completion of transmission of all of the data of the first data frame via the first wireless signal packet.Type: GrantFiled: August 30, 2022Date of Patent: January 23, 2024Assignee: MaxLinear, Inc.Inventor: Sigurd Schelstraete
