Patent number: 10674524Abstract: In some aspects, the disclosure is directed to methods and systems for coexistence management. A first access point operating in an unlicensed frequency band using a first RAT receives, from a second access point operating in the unlicensed frequency band using a second RAT, information regarding operation of the second access point in the unlicensed frequency band. It is determined, using the received information, that the first access point or the second access point is using a first share of the unlicensed frequency band that is below a predetermined threshold, indicating an imbalance of usage between the first RAT and the second RAT. A transmission parameter of the first access point for operating in the unlicensed frequency band using the first RAT is adjusted according to the determination.Type: GrantFiled: May 15, 2018Date of Patent: June 2, 2020Assignee: Avago Technologies International Sales Pte. LimitedInventors: Matthew J. Fischer, Baoguo Yang, Nelson Sollenberger, Yong Li, Vinko Erceg

Patent number: 10560850Abstract: In some aspects, the disclosure is directed to methods and systems for coexistence management. A first access point is scheduled a time to begin transmission of a packet to a user device in an unlicensed frequency band using a first RAT. The time to begin the transmission is scheduled to avoid transmission overlap with a second access point using a second RAT in the unlicensed frequency band, and scheduled according to information from the second access point regarding operation in the unlicensed frequency band using the second RAT. One of the first and second RATs includes one of a WLAN RAT or a LTE based RAT, and another of the first and second RATs includes a remaining one of the WLAN RAT or the LTE based RAT, in one or more embodiments. The first access point receives updated information regarding operation in the unlicensed frequency band using the second RAT.Type: GrantFiled: February 4, 2019Date of Patent: February 11, 2020Assignee: Avago Technologies International Sales Pte.

Publication number: 20190280789Abstract: Systems and methods allow LAA LTE equipment to coexist with other services in the unlicensed band such as WIFI or WLAN services. Systems and methods use LTE reference signals in the unlicensed spectrum that are not continuous and can be interrupted by a WIFI signal or other services in the unlicensed band or use a dynamic LAA ON burst or window to provide the LTE reference signals in some embodiments. The systems and methods can detect the presence of LTE signals using a one or more of a number of techniques.Type: ApplicationFiled: May 28, 2019Publication date: September 12, 2019Inventor: Baoguo Yang
