Abstract: This disclosure relates to techniques for a wireless device to detect and operate in an elevator or elevator-like conditions. The wireless device may establish a cellular link with a cellular base station. One or more conditions associated with being in an elevator may be detected. The wireless device may determine to operate in an elevator mode based at least in part on detecting the one or more conditions associated with being in an elevator. The wireless device may operate in the elevator mode. One or more conditions associated with exiting an elevator may be detected. The wireless device may determine to operate in a normal mode based at least in part on detecting the one or more conditions associated with exiting an elevator. The wireless device may operate in the normal mode.

Abstract: This disclosure relates to techniques for performing radio link monitoring and cell searching when moving at high speeds. A movement speed of a wireless device may be determined. When performing a cell search, the manner of the cell search may depend on the movement speed of the wireless device, potentially including cells that are associated with high movement speed being more highly prioritized when the wireless device is determined to be at a higher movement speed than when the wireless device is determined to be at a lower movement speed.

Abstract: A method for managing pending acknowledgement (ACK) packets in a communication device is provided. The method can include the communication device monitoring a status of a transmit queue for packets to be sent over a network; detecting a queue condition indicative of congestion causing a delay in sending one or more ACK packets pending in the transmit queue; and discarding a set of one or more ACK packets from the transmit queue in response to the queue condition. The discarded set of one or more ACK packets can include one or more oldest ACK packets of the ACK packets pending in the transmit queue. A most recent ACK packet pending in the transmit queue can remain pending in the transmit queue after the set of one or more ACK packets has been discarded.
