Abstract: A device and method selects an antenna configuration. The method performed at a user equipment includes determining at least one communication functionality that is being used, each communication functionality configured to utilize at least one antenna in a multi-antenna arrangement of the user equipment. The method includes receiving a first indication of whether a cellular communication functionality is being used, the cellular communication functionality configured to utilize at least one antenna in the multi-antenna arrangement. The method includes receiving a second indication of whether a coexistence condition is present. The method includes determining an antenna configuration for the multi-antenna arrangement to be used by the determined communication functionality based upon the determined communication functionality, the first indication, and the second indication. The method includes configuring the multi-antenna arrangement for the determined communication functionality based upon the antenna configuration.

Abstract: A method for facilitating in-device coexistence between wireless communication technologies on a wireless communication device is provided. The method can include transmitting data traffic from the wireless communication device via an aggressor wireless communication technology; determining occurrence of an in-device interference condition resulting from transmission of the data traffic via the aggressor wireless communication technology interfering with concurrent data reception by the wireless communication device via a victim wireless communication technology; and reducing a bit rate of the data traffic transmitted via the aggressor wireless communication technology in response to the in-device interference condition.

Abstract: A method for offloading a video portion of a video call form a cellular network to a WLAN is provided. The method can include a wireless communication device participating in a video call with a remote device over a connection between the wireless communication device and a cellular network. The video call can include a first video stream carried over a first bearer on the cellular network and an audio stream carried over a second bearer on the cellular network. The method can further include the wireless communication device establishing a connection between the wireless communication device and a WLAN; performing a call setup procedure with the remote device to establish a second video stream over the WLAN; terminating the first video stream; and using the second video stream and the audio stream to continue the video call.

Abstract: An approach is described for a wireless device comprising a transceiver and a processor communicatively coupled to the transceiver. The processor is configured to detect a packet for transmission; scan, using the transceiver, a channel during an initial sliding window, the initial sliding window having N symbol durations; determine a power distribution of the initial sliding window based on the channel scan; determine that the channel is occupied during a first time period of the initial sliding window based at least on the power distribution; and determine a second sliding window having a second time period and a third time period. The second time period overlaps with the initial sliding window and a length of the third time period is determined based at least on the power distribution. The processor is further configured to scan, using the transceiver, the channel during the third time period; determine that the channel is idle during the third time period of the second sliding window; and transmit, using the transceiver, the packet to a second wireless device on the channel responsive to the third time period being idle.

Abstract: A device implementing a system for coexistence of collocated radios may include a first radio circuit configured to receive, from a collocated second radio circuit, a start indication for cellular activity associated with a radio resource control connection. The first radio circuit may be configured to, responsive to receiving the start indication, stop a wireless transmission capability. The first radio circuit may be configured to receive, from the collocated cellular circuit, an end indication for the cellular activity prior to the radio resource control connection being released. The first radio circuit may be configured to resume the wireless transmission capability in accordance with a reduced power level response to receiving the end indication.

Abstract: A method for transitioning a video call is provided. The method can include a wireless communication device participating in a video call with a remote communication device via a first video call session established over a connection between the wireless communication device and a first cellular network. The video call can include a packet switched video stream carried over a first bearer and an audio stream carried over a second bearer. The method can further include the wireless communication device determining a degradation in a connection quality for the first cellular network; transitioning to a legacy cellular network having a circuit switched domain in response to the degradation in connection quality for the first cellular network; establishing a second video call session on the legacy cellular network; and using the second video call session to continue the video call on the legacy cellular network.
