摘要:
An apparatus and method are disclosed for effectively and efficiently arbitrating concurrent usage between WLAN and Bluetooth access technologies for co-located wireless devices. A state level arbiter determines state and relevant parameters of a WLAN module and of a Bluetooth module of a wireless transceiver unit. The state level arbiter uses the state and relevant parameters to determine which access technology (WLAN or Bluetooth) or combination of the access technologies (WLAN or Bluetooth) will provide the best concurrent performance for wireless transmissions at a given time for specific Bluetooth states and WLAN states.

An apparatus and method for multiple wireless service coexistence comprising: engaging a first switch to connect a first service transmitter to an antenna through a first filter path and to disconnect a first service receiver from the antenna; engaging a second switch to connect a second service receiver to the antenna through a second filter path and to disconnect a second service transmitter from the antenna; enabling transmit power control on the first service transmitter; and performing one or both of the following: a) transmitting a first service transmit signal through the first filter path to the antenna with high rejection of the band of a second service; b) receiving a second service receive signal through the second filter path from the antenna with high rejection of the band of a first service.

In a mobile device, interference between different radio access technologies (RATs) may be pronounced in the presence of effects of non-linearity. To decrease interference and improve performance, a device may operate a RAT in an improved linearity mode based upon operating conditions of one or more RATs operating in the mobile device. A device may also operate a RAT in an improved noise-figure mode.

Interference between potentially conflicting radio access technologies (RATs) in a wireless device may be managed through a coexistence manager. The coexistence manager allows a first active RAT to yield conflicting resources to a second idle RAT for purposes of receiving signals to allow proper operation by the second RAT. These signals may be, for example, paging signals to a Long Term Evolution (LTE) radio or beacons to a wireless local area network (WLAN) radio.

Various methods for controlling a device is disclosed including dynamically selecting a set of mappings defining how a gesture made by a movement of at least one wearable item will be interpreted as one or more commands; determining whether the gesture has a mapping in the set of mappings; and translating the gesture into a command for the device based on the determination. Interpreting movements of a wearable item as gestures associated with a command to control a controlled device is also disclosed that includes sensing a movement of the wearable item in context as being indicative of a gesture relating to the command based on the first context. A method for communicating control information by a wearable device is further disclosed including determining an agreed upon set of control gestures between first and second devices, wherein the control gestures are performable using the first device and are supportable by the second device; and participating in a control sequence to control the second device via a wireless transmission corresponding to at least one of the control gestures to be performed using the first device.
摘要:
A method of wireless communication includes partitioning coexistence tasks between short term policy setting tasks and policy implementing tasks, processing the short term policy setting tasks using a first set of computing resources, and processing the policy implementing tasks using a second set of computing resources. The first set may be software resources configured for slower execution of tasks and the second set may be hardware resources configured for just-in-time execution of tasks. The policy may determine a time after which a first radio event is not to be interrupted and granting or denying later events based on whether they would begin before or after the do-not-interrupt time. The do-not-interrupt time may be based on a weighted priority of the first radio event.

Aspects disclosed herein relate to improving NFC RF discovery through monitoring RF activity associated with one or more RATs. In one example, a first NFC device may be configured to use both a first RAT and NFC. The first NFC device may monitor RF activity on a first RAT to determine whether there is at least a greater probability that a second NFC device is within a threshold. The NFC device may be also configured to modify at least an interval between polling modes in a NFC RF discovery loop based on the determination.
摘要:
In a multi-radio user equipment, a power backoff or similar restraint may be placed on communications of a first radio, such as LTE, in order to protect operations of a second radio, such as Bluetooth, depending on the time remaining for completion of the communications of the second radio. Such protected operations may include paging or inquiry operations. A power backoff may be applied to an LTE radio in order to protect completion of the paging or inquiry operations. The power backoff may be increased as the time to completion of the paging or inquiry operations approaches.

A method for controlling a controlled device with a device wearable on a portion of a body is disclosed. The method includes detecting relative movement between the wearable device and the portion of the body; and generating an indication of the relative movement for use in controlling the controlled device. A method for controlling a controlled device with a device wearable on a portion of a body is also disclosed. The method includes receiving a message indicating a relative movement between the wearable device and the portion of the body; and generating an action to control the controlled device based on a command associated with the relative movement. Apparatuses for performing the methods are disclosed herein as well.
