Abstract
A base station or other device may have access to multiple channels for communicating with a mobile device or other client device. In some cases, these channels may include high power channels and low power channels, where the high power channels are in frequency bands in which higher power signals are legally allowed relative to those of channels in other frequency bands. When allocating bandwidth for use in communicating with the mobile device, the base station is configured to preferentially use channels using relatively low power signals over channels that use relatively high power signals.
Claims17
One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform actions comprising:
- communicating with multiple mobile devices of a cellular communication network, wherein communicating with the mobile devices is performed at least in part using (a) a licensed frequency band licensed to an operator of the cellular communication network, (b) a first unlicensed frequency band having a first coverage range, and (c) a second unlicensed frequency band having a second coverage range;
- the first and second unlicensed frequency bands being legally regulated for shared use by multiple communication networks;
- wherein radio signals within the first shared unlicensed frequency band are legally regulated to use no more than a first radio transmission power and radio signals within the second shared unlicensed frequency band are regulated to use no more than a second radio transmission power, the first radio transmission power being greater than the second radio transmission power;
- determining that a mobile device is within the second coverage range, wherein a time that the determining that the mobile device is within the second coverage range is performed is a first time;
- in response to determining that the mobile device is within the second coverage range, selecting the second shared unlicensed frequency band for radio communications with the mobile device;
- determining that the mobile device is not within the second coverage range, wherein a time that the determining that the mobile device is not within the second coverage range is performed is a second time;
- and
- in response to determining that the mobile device is not within the second coverage range, selecting the first shared unlicensed frequency band for radio communications with the mobile device,
- wherein the first time is different than the second time.

A base station for use within a cellular communication system, the base station comprising:
- one or more radio transceivers configured to communicate with multiple devices of the cellular communication system at least in part using a first frequency band and a second frequency band;
- wherein radio signals within the first frequency band are legally regulated to use no more than a first transmission power and radio signals within the second frequency band are legally regulated to use no more than a second radio transmission power, the first radio transmission power being greater than the second radio transmission power;
- one or more processors;
- one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform actions comprising:
- determining an ability to communicate with a device using the second frequency band, wherein a time that the determining the ability to communicate with the device using the second frequency band is performed is a first time;
- in response to determining the ability to communicate with the device using the second frequency band, preferentially selecting the second frequency band over the first frequency band for communicating with the device;
- determining an inability to communicate with the device using the second frequency band, wherein a time that the determining the inability to communicate with the device using the second frequency band is performed is a second time;
- and
- in response to determining the inability to communicate with the device using the second frequency band, using the first frequency band for communicating with the device,
- wherein the first time is different than the second time.
7 more elements
A method, comprising:
- communicating with multiple devices at least in part using a first frequency band and a second frequency band, wherein radio signals within the first frequency band use no more than a first radio transmission power and radio signals within the second frequency band use no more than a second radio transmission power, the first radio transmission power being greater than the second radio transmission power;
- determining an ability to communicate with a device using the second frequency band, wherein a time that the determining the ability to communicate with the device using the second frequency band is performed is a first time;
- in response to determining the ability to communicate with the device using the second frequency band, using the second frequency band preferentially over the first frequency band for communicating with the device;
- determining an inability to communicate with the device using the second frequency band, wherein a time that the determining the inability to communicate with the device using the second frequency band is performed is a second time;
- and
- in response to determining the inability to communicate with the device using the second frequency band, using the first frequency band for communicating with the device,
- wherein the first time is different than the second time.
