IEEE 802.11 devices can operate on frequencies that are licensed by national regulatory bodies. Although this standard has been generalized so that it is indepcndant of license type. band, and country of operation. only the bands and associated regulations listed in Annex I have been specifically considered. Dynamic STA enabtement (DSE) in licensed bands
The DSE operating procedures are used to automate the channel permissioning and regulatory controls needed for unregistered IEEE 802.11 STAs to operate as dependent STAs in licensed spectrum. Contention-Based Protocol (CBP) in nonexclusively licensed bands
The granting of licenses on a nonexclusive. uncoordinated basis in the same area leads to the possibility of overlapping networks. When overlapping networks cause co-channel interference, regulations, such as those governing the 3650 MHz band in the United States, require the use of a CBP “by which a transmitter provides reasonable opportunities for other transmitters to operate.” 3 IEEE 802.11 carrier sense multiple access with collision avoidance (CSMAICA) is suitable for this purpose in most situations. Using DSE STA identification to resolve interference
When L’SMACA is not able to sufficiently sense the presence of another licensee’s STA (i.e.. a hidden STA) or if a secondary licensee causes inkrence to a primary licensee, the licensee is obliged to resolve complaints that result from intcrkrence caused by any STA under its control (including dependent STAs). In order to facilitate the interference resolution processes. all STAs operating in nonexclusively licensed spectrum use the DSE STA and location information procedures.
The STA identification and location infarmation procedures are inherently tied because, by default. registered STAs broadcast their actual location as their unique identifier. Dependent STAs broadcast the location of the STA that has enabled them as well as a unique code selected by the licensee. This method ensures that a victim of the interkrence is always put in contact with the party responsible for rectifying the problem, and, at the same time, it protects the privacy of the dependent STA’s operator. Further coexistence enhancements In nonexclusively licensed bands
While not explicitly required to meet specific rules, a number of optional IEEE 802. II mechanisms, when used togeher, are able to meet general requirements for spectrum sharing, incumbent detection, and other cognitive radio functions in licensed bands. The specific mechanisms for each band are detailed in J.2.IEEE 802 11Y pdf download.
