Patent number: 9532311Abstract: In response to determining that a Bluetooth inquiry phase or the Bluetooth paging phase will begin, a power save indicator signal is sent from a first communication device to a second communication device prior to a start of the Bluetooth inquiry phase or the Bluetooth paging phase. A gap between a first Bluetooth communication slot and a second Bluetooth communication slot is determined, and a time period within the gap is determined, where an end of the time period occurs at a defined amount of time prior to a start of the second Bluetooth communication slot. During the time period, one or more power save poll messages are sent from the first communication device to the second communication device, each first power save poll message prompting the second communication device to transmit a respective first WLAN packet to the first communication device.Type: GrantFiled: August 24, 2015Date of Patent: December 27, 2016Assignee: Marvell International Ltd.Inventors: Kapil Chhabra, Zhenyu Zhang, Milind Kopikare, Deepak Jain, Robert Mack, Gladys Yuen Yan Wong, Li-Fu Jeng, Ronak Anjan Chokshi

Patent number: 9326235Abstract: A circuit processes requests to access an antenna, the requests from a plurality of wireless communication protocols components including (i) a first wireless communication protocol component and (ii) a second wireless communication protocol component. The circuit causes a switch to provide the second wireless communication component with access to the antenna while the circuit is in a power saving mode of operation, and, upon the circuit exiting the power saving mode of operation, determines whether the second wireless communication component is utilizing the antenna. The circuit, upon the circuit exiting the power saving mode of operation, applies a first set of arbitration rules when it is determined that the second wireless communication component is utilizing the antenna, and, upon the circuit exiting the power saving mode of operation, applies a second set of arbitration rules when it is determined that the second wireless communication component is not utilizing the antenna.Type: GrantFiled: May 5, 2014Date of Patent: April 26, 2016Assignee: MARVELL INTERNATIONAL LTD.Inventors: Gladys Yuen Yan Wong, Ken Yeung

Patent number: 9246522Abstract: An arbiter circuit receives a plurality of media access request signals from multiple protocol processing devices, and generates a plurality of media access grant indicators using i) the plurality of media access request signals, and ii) coexistence arbitration rules. A selector circuit receives the plurality of media access grant indicators from the arbiter circuit, and when the plurality of media access grant indicators indicate more than one protocol processing device is authorized to access an antenna, determines a compatibility of the more than one protocol processing device simultaneously accessing the antenna. The selector circuit, based on i) the plurality of media access grant indicators, and ii) the determined compatibility of the more than one protocol processing device simultaneously accessing the antenna, controls one or more switches to selectively enable antenna paths in a plurality of antenna paths coupled to the antenna.Type: GrantFiled: December 8, 2014Date of Patent: January 26, 2016Assignee: MARVELL INTERNATIONAL LTD.Inventors: Gladys Yuen Yan Wong, George Lee

Patent number: 9131520Abstract: The present specification describes techniques for packet exchange arbitration. In some embodiments, a request is maintained to an arbiter at least until a packet exchange has been communicated and/or at least until a time-sensitive packet is communicated. In some other embodiments, a grant of a request is delayed at least until the communication of an isochronous packet.Type: GrantFiled: August 11, 2014Date of Patent: September 8, 2015Assignee: Marvell International Ltd.Inventors: Todd Steven Wheeler, Gladys Yuen Yan Wong, Robert Mack, Ken Kinwah Ho
