Abstract
A system and method for coordinating radio resource usage in an unlicensed frequency band (24) is provided. Specifically, under the present invention, a set of spectrum etiquette rules is provided that govern how radio systems (20A-C) operate within unlicensed frequency bands (24). In a typical embodiment, the set of spectrum etiquette rules can accommodate radio systems (20A-C) operating at varying channel bandwidths. To this extent, the set of spectrum etiquette rules generally includes: a channel switching rule; a bandwidth selection rule; a power selection rule; a deferring listen before talk (LBT) rule; a channelized LBT rule; and a synchronized LBT rule.
Claims30
A system for coordinating radio resource usage in an unlicensed frequency band, comprising:
- a plurality of radio systems (20A-C) operating in the unlicensed frequency band (24);
- and
- a set of spectrum etiquette rules for coordinating radio resource usage by the plurality of radio systems (20A-C), wherein the set of spectrum etiquette rules includes a channel switching rule for determining a frequency channel of operation for at least one of the plurality of radio systems (20B) based on a proximity of the frequency channel of operation to an in-use frequency channel of operation that is associated with the at least one of the plurality of radio systems (20B)
A system for coordinating radio resource usage in an unlicensed frequency band, comprising:
- a plurality of radio systems (20A-C), wherein the plurality of radio systems (20A-C) includes a reference channel radio system (20A), a narrow channel ratio system (20B) and a wide channel radio system (20C), and wherein a reference channel bandwidth (22) is defined based on the reference channel radio system (20A);
- and
- a set of spectrum etiquette rules for coordinating radio resource usage by the plurality of radio systems (20A-C), wherein the set of spectrum etiquette rules includes a channel switching rule for determining a frequency channel of operation for the narrow channel radio system (20B) based on a proximity of the frequency channel of operation to an in-use frequency channel of operation that is associated with the narrow channel radio system (20B).
A method for coordinating radio resource usage in an unlicensed frequency band, comprising:
- defining a reference channel bandwidth (22) based on a reference channel radio system (20A);
- and
- determining a frequency channel of operation for a narrow channel radio system (20B) based on a proximity of the frequency channel of operation to an in-use frequency channel of operation that is associated with the narrow channel radio system (20B).
A radio device operating in an unlicensed frequency band, comprising:
- means for enacting a set of spectrum etiquette rules for coordinating radio resource usage by the radio device, wherein the set of spectrum etiquette rules includes a channel switching rule for determining a frequency channel of operation for the radio device based on a proximity of the frequency channel of operation to an in-use frequency channel of operation that is associated with the radio device.
