Patent number: 11115997Abstract: Apparatus and methods for time division based communication between a wireless device and a wireless network in a licensed radio frequency (RF) band and an unlicensed RF band are disclosed. The wireless device receives downlink control information (DCI), via a primary component carrier (PCC) of a primary cell (Pcell) in the licensed RF band, indicating downlink (DL) data transmission via a secondary component carrier (SCC) of a secondary cell (Scell) in the unlicensed RF band. The wireless device receives via the SCC part of the DL data transmission and transmits a control message via the PCC in response. The wireless device sends a scheduling request (SR) to the eNodeB and receives uplink (UL) transmission opportunities in a combination of the licensed RF band and the unlicensed RF band. The wireless device performs a clear channel assessment before reserving and transmitting to the eNodeB in the unlicensed RF band.Type: GrantFiled: February 11, 2019Date of Patent: September 7, 2021Assignee: Apple Inc.Inventors: Farouk Belghoul, Tarik Tabet, Syed A.

Patent number: 11032757Abstract: Passive and active scanning for extended range wireless networking. The choice between legacy and extended range signaling can depend on one or more factors. For passive scanning, an electronic device may transmit a combination of legacy beacons and extended range beacons for network discovery by receiving electronic devices. For active scanning, an electronic device may transmit extended range probe requests in addition to legacy probe requests to discover all of the access points within its transmission range. Responses to probe requests can use extended range, legacy, single user, and/or multi user protocols.Type: GrantFiled: February 24, 2020Date of Patent: June 8, 2021Assignee: Apple Inc.Inventors: Jarkko L. Kneckt, Christiaan A. Hartman, Guoqing Li, Joonsuk Kim, Matthew L. Semersky, Oren Shani, Syed A. Mujtaba, Yong Liu

Patent number: 10986571Abstract: A station (STA) of a wireless local area network (WLAN) transitions implicitly between power management (PM) modes or PM states, without providing an explicit indication of the PM mode/state change to an access point (AP) of the WLAN. Transitions include changes between an active mode and a power save (PS) mode, or between an awake state and a doze state of the PS mode. Transitions occur immediately after receipt of a beacon indicating pending data for the STA, after an offset time indicated in the beacon, or at a specific wake time negotiated with the AP. After data reception is complete, the STA transitions implicitly to the PS mode or a doze state of the PS mode, after a power save inactivity timeout period or after receiving an indication that data transmission is complete.Type: GrantFiled: September 19, 2018Date of Patent: April 20, 2021Assignee: Apple Inc.Inventors: Chiu Ngok E. Wong, Syed A. Mujtaba, Christiaan A. Hartman, Joonsuk Kim

Patent number: 10470126Abstract: In order to reduce power consumption of an electronic device during communication with another electronic device in a wireless local area network (WLAN), the electronic device analyzes fields in a given packet prior to a payload of the given packet to look for information that specifies a destination of the given packet. For example, the information may include: a full associated identification (AID) of the destination, a partial media-access-control (MAC) address of the destination; and/or a compressed (MAC) address of the destination. The information may be included in the preamble of the given packet. In particular, the information may replace length information in a high-throughput signal field in the given packet. Moreover, if the destination is other than the electronic device, the electronic device dumps the given packet and changes a power state of the electronic device, thereby reducing the power consumption.Type: GrantFiled: March 16, 2017Date of Patent: November 5, 2019Assignee: APPLE INC.Inventors: Joonsuk Kim, Syed A.

Patent number: 10153868Abstract: Apparatus and methods for a hybrid automatic repeat request (H-ARQ) mechanism for wireless communication devices of a wireless local area network (WLAN) are disclosed. Methods and apparatus to determine whether a packet is an original, first transmission or a retransmission of a previously transmitted packet without decoding the payload of the packet are disclosed. Medium access control (MAC) addresses of a transmitter, such as an access point (AP), and a receiver, such as a station (STA), of a WLAN are encoded separately with a retransmission bit to indicate whether the packet is retransmitted. For an aggregated MAC protocol data unit (A-MPDU), a sequence number is included to determine which MAC protocol data units (MPDUs) of the A-MPDU are retransmitted. When retransmission is indicated, the receiver of the STA performs a hybrid automatic repeat request (H-ARQ) process to combine the retransmitted packet with previously received packets.Type: GrantFiled: June 9, 2016Date of Patent: December 11, 2018Assignee: Apple Inc.Inventors: Joonsuk Kim, Yuchul Kim, Syed A.
