    摘要： A network node for providing resource management in a wireless network based on indicated application. The network mode is configured to receive a service request message transmitted by a user equipment, the service request message comprising an application identifier associated with a mobile application executable on the user equipment and a request for network resources to be allocated to the mobile application. The network node is also configured to determine whether the network is capable of handling the service request based at least partly upon the application identifier. In response to the determination, the network node transmits to the user equipment a response message indicating whether the network node accepts the request for network resources to be allocated to the mobile application.

    摘要： A method of generating an interleaved symbol sequence location from a symbol location of a symbol sequence comprises determining the interleaved symbol location based on an interleaver sequence function which relates a linear symbol location to the interleaved symbol location. This is done by acquiring values of the interleaver sequence function in quotient and remainder form and then calculating the interleaved symbol location by performing operations of the interleaver sequence function in quotient and remainder form.

    摘要： Audio input may be received at one or more microphones of a mobile device. Based on the audio input, a change in an acoustic environment of the device, such as a change in a direction of arrival of the audio input or a degradation in a quality of acoustic echo cancellation being performed upon the audio input, may be detected. A determination may be made that the detected change coincides with a non-acoustic physical event detected using an auxiliary sensor at the mobile device. The event may for example be device motion, a new proximate object, a change in a proximity of an object, a new heat source or a change in a heat level from a known heat source. Based on the determining, a signal processor, possibly comprising an audio beamformer or echo canceller, may be recalibrated, e.g. the audio beamformer or echo canceller may be caused to reconverge.
