摘要:
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.

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.

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.
摘要:
Automatically discovering and re-establishing wireless connections to other devices in a mobile computing environment (MCE) may be achieved by monitoring connections of different devices with the UE, correlating the connections of the different devices, determining an MCE based on the correlations, and storing information associated with the MCE. A known MCE may accordingly be automatically detected based on an identification of at least one of the different devices, for example, and connection with one or more of the different devices may be automatically re-established to re-establish the MCE based on the stored information.
摘要:
A method of wireless communication includes monitoring coexistence issues among supported radios in a User Equipment (UE). The method includes configuring a UE with first and second filter configurations. The first filter configuration covers a first frequency band, for example a portion of the ISM band. The first filter configuration may be wider than the second filter configuration, which excludes a portion of the first frequency band that is adjacent to a proximate second frequency band, for example LTE Band 7 or LTE Band 40. The UE selects between the first and second filter configurations based on the frequency of a first UE event. If the UE event is in a frequency in the adjacent portion excluded by the second filter configuration, the UE arbitrates depending on event priority. The second filter configuration may be chosen to reduce or minimize arbitration.

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.
摘要:
A method of wireless communication includes determining a frame offset between communications of a first communication resource (e.g., an LTE radio) and communications of a second communication resource (e.g., a Bluetooth or WLAN radio). The method also includes determining potential time slot configurations for the communications of the second communication resource. A time slot configuration is selected from the determined potential time slot configurations, to reduce degradation of the first communication resource due to conflicting time slots between the first communication resource and the second communication resource, based on the determined frame offset. The selection may be based on the determined frame offset.

Systems, methods, and devices synchronize data streams by hashing received data frames to generate a sequence of hash values, comparing the generated hash value sequence to a hash value sequence received in a control stream, and processing data frames when the hash value sequences match. A source device and multiple receiver devices may synchronize audio data encoded in data frames, applying a hash function to each data frame to generate a first sequence of hash values, transmitting the data frames on a first channel and the first sequence of hash values on a control channel, receiving the data frames and the first sequence of hash values in the receiver devices, applying the hash algorithm to received data frames to generate a second sequence of hash values, comparing the first and second sequences of hash values, and processing data frames when the first and second sequences of hash values match.

A method for communicating control information by a wearable device is disclosed. The method includes determining a first movement according to a first degree of freedom as being gesture-related and a second movement according to a second degree of freedom as being gesture-related; generating a first set of possibly performed gestures based on the first movement; generating a second set of possibly performed gestures based on the second movement; inferring, from the first and second sets, whether the first movement is representative of an intended command; and transmitting information based on the inference. An apparatus for performing the method is also disclosed.
摘要:
An embodiment of the invention may include a method of receiving a transmission at a receiver. The method may include setting a receive window duration for receiving the transmission based on an elapsed time since last receiving a good transmission. The receive window duration may be a nonlinear function of the elapsed time. The method may further include opening a receive window to listen for the transmission for an amount of time equal to the set receive window duration.
