摘要:
A wireless device comprises a first wireless transceiver, a second wireless transceiver, and control logic. The control logic is coupled to the first wireless transceiver and the second wireless transceiver. The control logic is configured to determine whether to transmit protection frames (e.g., clear-to-send 2 self frames) based upon sequence numbers in frames received from another device.

A wireless device includes a first wireless transceiver and a second wireless transceiver. The first wireless transceiver is configured to communicate via a first wireless network, and includes a first scheduler configured to schedule communication via the first wireless network. The second wireless transceiver is configured to communicate via a second wireless network. The second wireless transceiver includes a second scheduler. The second scheduler is configured to identify a resource allocated to the second wireless transceiver for a transaction via the second wireless network, to identify a portion of the resource used by the second wireless transceiver for the transaction, and to transfer information defining the portion to the first transceiver. The first scheduler is also configured to schedule, based on the information transferred by the second scheduler, the first transceiver to communicate via the first wireless network using the resource allocated to the second wireless transceiver for the transaction.

In accordance with at least some embodiments, a system comprises an access point and a station in communication with the access point. The station has at least two network technology subsystems subject to coexistence interference. The station selectively implements bounded Power Save (PS)-Polling (BPS) logic to handle communications between the station and the access point. The BPS logic operates to confine PS-Poll transmissions starts to one of two separate windows during a medium grant duration of the station.

In accordance with at least some embodiments, a system includes an access point and a station in communication with the access point. The station selectively implements adaptive periodic Power-Save (APPS)-Polling logic for communications between the station and the access point. The APPS-Polling logic is configured to determine a timer value for periodic PS-Polling by monitoring a periodicity of arrival packets for at least a threshold amount of time.

Apparatus and method for providing fine timing assistance to global navigation satellite systems (GNSS) via wireless local area network (WLAN). In one embodiment, a method for synchronizing a global navigation satellite system (GNSS) receiver includes receiving, by a wireless device, via a wireless local area network (WLAN), fine time assistance information transmitted by an assisting device connected to the WLAN. A time value of a GNSS clock of the wireless device is adjusted based on the fine time assistance information. Based on the adjusted time value, GNSS codes of a GNSS positioning signal are acquired by the wireless device.

A system and method for protecting a wireless device including co-located network transceivers from uplink starvation are disclosed herein. A wireless device includes a first wireless transceiver and a second wireless transceiver respectively configured for communication via a first wireless network and a second wireless network. The wireless device further includes logic that determines which of the first and second transceivers is enabled to transmit at a given time. The logic determines a duration of a pending transmission via the first transceiver, and determines a predicted start time of a predicted transmission via the second transceiver. Based on the duration and the predicted start time, the logic transmits a notification signal indicating that a receiving device should refrain from transmitting on the first network for a reserved time ending after the pending transmission starts. The pending transmission starts following completion of the predicted transmission.
摘要:
A method of obtaining timing parameters between wireless station peers using reduced power. A timing measurement protocol is executed a including a plurality of Timing Measurement Action (TMA) frames between a first wireless station (STA1) and a second STA (STA2) within a wireless network. The plurality of TMA frames span a communications interval and include timing information. A power-save protocol is employed by at least one of STA1 and STA2 during execution of the timing measurement protocol during one or more sub-intervals between the plurality of TMA frames. STA1 or STA2 computes at least one timing parameter using the timing information.

Apparatus and methods for scanning for access points (APs) for wireless local area network (WLAN) positioning. In one embodiment a wireless device includes a WLAN positioning system. The WLAN positioning system includes an AP scanner. The AP scanner is configured to determine which WLAN channels are being used by APs proximate to the wireless device. The AP scanner is also configured to scan for AP transmissions only the WLAN channels determined to be used by APs proximate to the wireless device. The AP scanner is further configured to extract signal strength and AP identification information for WLAN positioning from the AP transmissions on the scanned channels.

A system and method for operating an FM system and wireless networking system coexistent in a mobile wireless device. A mobile wireless device includes a frequency modulation (“FM”) system that includes an FM transmitter and, optionally, an FM receiver. The mobile wireless device also includes a wireless networking system having a network receiver. The FM system is configured to disable the FM transmitter if an amplitude of a modulating signal provided to the FM transmitter is below a predetermined threshold.
