Publication number: 20230223986Abstract: A radio communications device includes a RTC configured to run even during sleep for receiving from a coordinator node (CN) in an asynchronous channel hopping WPAN an asynchronous hopping sequence (AHS) frame that includes the CN's hopping sequence. A processor implements a stored sleepy device operation in asynchronous channel hopping networks algorithm. The algorithm is for determining a time stamp for the AHS frame and the CN's initial timing position within the hopping sequence, storing the time stamp, going to sleep and upon waking up changing a frequency band of its receive (Rx) channel to an updated fixed channel. A data request command frame is transmitted by the device on the CN's listening channel that is calculated from the CN's hopping sequence, time stamp, CN's initial timing position and current time, and the device receives an ACK frame transmitted by the CN at the updated fixed channel of Rx operation.Type: ApplicationFiled: March 17, 2023Publication date: July 13, 2023Inventors: KUMARAN VIJAYASANKAR, ROBERT LIANG, JYOTHSNA KUNDURU, KWANG SEOP EOM

Patent number: 10499428Abstract: A method of channel access for a radio device in an asynchronous channel hopping wireless network. A backoff time is set from an Interference Avoidance Delay plus a random backoff time for transmissions from the radio device. For initial frame transmissions, an initial value for a number of backoffs (nb) and initial number of preamble detection backoffs (npdb) is set. After waiting for expiring of the initial backoff time and provided a current npdb_value<a predetermined maximum npdb value, a first CCA is performed on the radio device's receive (Rx) channel, and a value for npdb is incremented following a failure. A second CCA is performed on a target radio device's Rx channel, wherein a value for nb is incremented following a failure. Provided a not busy is determined in the second CCA the radio device transmits a frame on the target radio device's Rx channel.Type: GrantFiled: August 24, 2018Date of Patent: December 3, 2019Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Kumaran Vijayasankar, Jyothsna Kunduru

Patent number: 10313991Abstract: A method of channel access for a radio device in an asynchronous channel hopping wireless network includes a channel hopping coordinator first radio device transmitting its receive (Rx) channel hopping sequence to a fixed or semi-channel hopping sleepy radio device. The sleepy radio device tracks the first radio device's Rx channel using the channel hopping sequence and transmits a poll frame exclusive of a unicast schedule information element (US-IE) on the first radio device's current Rx channel to the first radio device. The sleepy radio device moves to an updated Rx channel that is a function of the current Rx channel. The first radio device receives the poll frame and then computes the updated Rx channel as the function of the current Rx channel. After the computing, the first radio device transmits a data frame to the sleepy radio device on the updated Rx channel.Type: GrantFiled: September 1, 2017Date of Patent: June 4, 2019Assignee: Texas Instruments IncorporatedInventors: Kumaran Vijayasankar, Arvind Kandhalu Raghu, Jyothsna Kunduru
