This application claims the benefit of U.S. provisional application 60/669,599, filed on Apr. 8, 2005, and U.S. provisional application 60/684,452, filed on May 25, 2005, which are incorporated by reference as if fully set forth.
Tx power step Minimum and maximum Tx power and adjustment
sizes step size settings that the MP supports
Rx power step Minimum and maximum Rx power and adjustment
sizes step size settings, sensitivity levels and CCA
thresholds settings that the MP supports
Mode The operational modes (e.g., 802.11a, b, g, n, j, etc.)
the MP is able to support
Bandwidth The operational bandwidth that the MP is able to
support (e.g., 802.11n supports bandwidths of
10/20/40 MHz and 802.11j supports 10 or 20 MHz
bandwidths)
Freq. Bands The number of bands and sub-bands on which the
MP is capable of simultaneous operation (e.g., 2.4 GHz,
5 GHz, 5 GHz Lower U-NII, 5 GHZ Middle U-
PM Info PM address or PM identifier
Mode Regulatory domain within which the Mesh network
currently operates (e.g., 802.11b, g, n, j, etc.)
Freq. Bands frequency bands and sub-bands within which the
Mesh network currently operates
Tx Power minimum, instantaneous, and maximum allowed
Rx Power minimum, instantaneous, and maximum allowed
Rx power settings
CCA minimum, instantaneous, and maximum allowed
CCA threshold settings
Timing validity timers or time-out values
Measurement measurement intervals and configuration
Silence silence periods
Offset temporary offset values for any of the above plus
associated life-time values
For example, assume MP 501 receives MATPS_vector which comprises two vector value settings 505, 506: MATPS—1=20 dBM from MP 502 and MATPS—2=10 dBm from MP 503. Also assume that MP 501's own MATPS setting is configured to be MATPS_own=15 dBm. In the preferred implementation, the function F will determine the minimum MATPS value from all its inputs (i.e., min(10,20,15)=10 dBM) and the MP 501 will use an operational MATPS value when setting its Tx Power and it will signal it as part of the allowed power setting information that the MP 501 signals to other MPs, including MP1 and MP2. Accordingly, the operational MATPS 507 in terms of function F can be expressed as follows:
MATPS_operational = ⁢ F ⁡ ( MATPS_own , MATPS_vector ) = ⁢ min ⁡ ( MATPS_own , MATPS_vector ) . Equation ⁢ ⁢ ( 1 )
In an alternative embodiment, the MP 501 uses the value MATPS_operational determined by Equation (1) while determining its Tx Power, but MP 501 signals the MATPS_own value as its allowed power setting information to the other MPs, MP502 and MP503.
FIG. 7 shows a signaling diagram for identifying the Mesh PM according to the preferred methods described above. A PM Request Information Element (IE) is included as part of a broadcast/multicast/unicast signaling frame in signal 711 sent through the Mesh by MP 701 indicating to neighbor MPs MP702-MPN that a PM selection is required. This IE contains the address of the originating MP and other parameters, such as time-out values, selection criteria, default identifier for the proposed PM, reply-to address, and so on. A PM Response IE part of a broadcast/multicast/unicast signaling frame in signals 712 is sent through the Mesh containing the selection criteria response from the neighbor MPs MP702-MPN. A comparison procedure 713 is initiated in the MP701 where the selection criteria responses 712 1 . . . 712 N from the different neighbor MPs are evaluated. The PM selection decision is made based on which MP meets the requirements in terms of the chosen selection criteria, (e.g., highest random number draw or similar). The MP 701 broadcasts its final selection for PM to the Mesh in signal 713.
