Abstract
This disclosure provides coexistence strategies for a combined wireless communications device using multiple wireless protocols, such as WLAN and LTE. Transmission power of a system using one wireless protocol is dynamically adjusted based on a determination of operating characteristics of a system using another wireless protocol. At least one of the operating characteristics may be determined from an allocation of network resources, examples of which include the transmission frequency for an upcoming transmission and the transmission power for an upcoming transmission. Further, the transmission power may be adjusted when the reception quality of the system using the other wireless protocol is below a desired threshold.
Claims27
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;
- predict intermodulation distortion (IMD) regarding an upcoming transmission using the first transceiver based, at least in part, on at least one characteristic determined from the allocation of network resources;
- and
- selectively reduce transmit power at the second transceiver based, at least in part, on the predicted IMD when reception quality at the first receiver is below a desired threshold.
A method for providing coexistence between a first wireless protocol and a second wireless protocol, comprising:
- receiving an allocation of network resources using the a first transceiver configured to operate using the first wireless protocol;
- predicting intermodulation distortion (IMD) regarding an upcoming transmission at the first transceiver based, at least in part, on at least one characteristic determined from the allocation of network resources;
- and
- selectively reducing transmit power at a second transceiver configured to operate using the second wireless protocol based, at least in part, on the predicted IMD when reception quality at the first receiver is below a desired threshold.
A non-transitory processor-readable storage medium for providing coexistence between a first wireless protocol and a second wireless protocol in a wireless communications device, the processor-readable storage medium having instructions thereon, when executed by a processor, to cause the wireless communications device to:
- receive an allocation of network resources using the a first transceiver configured to operate using the first wireless protocol;
- predict intermodulation distortion (IMD) regarding an upcoming transmission at the first transceiver based, at least in part, on at least one characteristic determined from the allocation of network resources;
- and
- selectively reduce transmit power at a second transceiver configured to operate using the second wireless protocol based, at least in part, on the predicted IMD when reception quality at the first receiver is below a desired threshold.
