Systems and methods for scheduling wireless communications

摘要

This disclosure provides coexistence strategies for a combined wireless communications device using multiple wireless protocols, such as WLAN and LTE. One or more periods having increased interference potential during an upcoming communication event of one wireless protocol may be identified and the transmission duration of another wireless protocol may be dynamically adjusted to reduce interference. In one aspect, a first period of potential interference during an upcoming LTE transmission may be predicted based on allocated LTE transmission power. The duration of the transmission may be adjusted so that a response to the transmission does not arrive during the first period. In another aspect, a second period of potential interference during an upcoming LTE reception may be predicted based on an estimated quality of LTE reception. The duration of the transmission may be adjusted so that the transmission does not being during the second period.

主权项

1. A wireless communications device, comprising:
a first transceiver configured to operate using a first wireless protocol: a second transceiver configured to operate using a second wireless protocol; and a coexistence manager configured to:
receive an allocation of network resources using the first transceiver;identify a first period of potential interference regarding an upcoming transmission using the first transceiver based, at least in part, on a characteristic determined from the allocation of network resources; andadjust a nonzero transmission duration of the second transceiver so that a response, triggered by a transmission using the second transceiver, does not arrive during the first period of potential interference.
