A method for allowing a node in a wireless communication network to access time slot assignment information on multiple channels includes assigning the node to a first channel associated with a channelized neighborhood having a plurality of nodes. The node communicates in accordance with an access protocol having a common channel frame portion and a channelized frame portion. A plurality of staggered channelized bootstrap slot sections are provided in the channelized frame portion. Each channelized bootstrap slot section is associated with a different channel and offset in time from the other channelized bootstrap slot sections.

What is claimed is: 1. A method for allowing a node in a wireless communication network to access time slot assignment information on multiple channels, the node communicating in accordance with an access protocol having a common channel frame portion and a channelized frame portion, the method comprising: assigning the node to a first channel associated with a channelized neighborhood having a plurality of nodes; providing a plurality of staggered channelized bootstrap slot sections in the channelized frame portion, each channelized bootstrap slot section associated with a different channel and offset in time from the other channelized bootstrap slot sections; wherein the node is configured to participate in and exchange the time slot information on the multiple channels by switching from the first channel to one of the different channels during the channelized bootstrap slot section associated with the one of the different channels. 2. A method according to claim 1, wherein the access protocol is a multi-channel time division multiple access protocol. 3. A method according to claim 2, wherein the multichannel time division access protocol is orthogonal division multiple access. 4. A method according to claim 1, wherein the common channel frame portion includes synch slots and global bootstrap slots. 5. A method according to claim 1, wherein the channelized frame portion further includes a plurality of user traffic slot sections, each user traffic slot section associated with a different channel. 6. A method according to claim 1, wherein during the channelized frame portion, the node participates in a channelized bootstrap slot section associated with the first channel and a channelized bootstrap slot section associated with at least one other channel. 7. A method for providing a non-advantaged node in a wireless communication network access to time slot assignment information on a channel associated with an advantaged node, the non-advantaged node and advantaged node communicating in accordance with an access protocol having a common channel frame portion and a channelized frame portion, the method comprising: assigning the non-advantaged node to a first channel associated with a channelized neighborhood having a plurality of nodes; providing a first channelized bootstrap slot section for the first channel in the channelized frame portion; providing a second channelized bootstrap slot section for a channel associated with the advantaged node in the channelized frame portion, the second channelized bootstrap slot section offset in time from the first channelized bootstrap section; and switching the non-advantaged node to the channel associated with the advantaged node during the second channelized bootstrap slot section offset in time from the first channelized bootstrap section. 8. A method according to claim 7, wherein the advantaged node transmits data with at least one other advantaged node during the first channelized bootstrap slot section. 9. A method according to claim 7, wherein during the second channelized bootstrap slot section, the non-advantaged node exchanges local time slot assignment information with the advantaged node. 10. A method according to claim 7, wherein the access protocol is a multi-channel time division multiple access protocol. 11. A method according to claim 10, wherein the multi-channel time division access protocol is orthogonal division multiple access. 12. A method according to claim 7, wherein the common channel frame portion includes synch slots and global bootstrap slots. 13. A method according to claim 7, wherein the channelized frame portion further includes a plurality of user traffic slot sections, each user traffic slot section associated with a different channel. 14. A wireless communication network comprising: a plurality of channelized neighborhoods, each channelized neighborhood including a plurality of nodes assigned to a channel; a multi-channel time division multiple access structure having a common channel frame portion and a channelized frame portion, the multi-channel time division multiple access structure including: a slot assignment protocol; a plurality of synch slots in the common channel frame portion; a plurality of global bootstrap slots in the common channel frame portion; a plurality of staggered channelized bootstrap slot sections in the channelized frame portion, each channelized bootstrap slot section associated with a different channel and offset in time from the other channelized bootstrap slot sections; and a plurality of user traffic slot sections, each user traffic slot section associated with a different channel; wherein at least two of the staggered channelized bootstrap sections associated with different channels and offset in time are associated with a common node of the plurality of nodes. 15. A network in accordance with claim 14, wherein the multi-channel time division multiple access structure is an orthogonal domain multiple access structure. 16. A network according to claim 14, wherein a node assigned to a first channelized neighborhood of the plurality of channelized neighborhoods associated with a first channel accesses time slot assignment information on a first channelized bootstrap slot section associated with the first channel and on a second channelized bootstrap slot section associated with a second channel. 17. A network according to claim 14, wherein the slot assignment protocol is unifying slot assignment protocol. 18. A wireless communication network, comprising: at least one advantaged node; a plurality of non-advantaged nodes including at least one access point node, the access point node configured to communicate with the at least one advantaged node; a first channelized neighborhood including a first subset of the plurality of non-advantaged nodes assigned to a first channel including the access point node; a second channelized neighborhood including the at least one advantaged node and assigned to a second channel; a multi-channel time division multiple access structure having a common channel frame portion and a channelized frame portion, the multi-channel time division multiple access structure including: a slot assignment protocol; a plurality of synch slots in the common channel frame portion a plurality of global bootstrap slots in the common channel frame portion; a first channelized bootstrap slot section for the first channel in the channelized frame portion; a second channelized bootstrap slot section for the second channel in the channelized frame portion, the second channelized bootstrap slot section offset in time from the first channelized bootstrap slot section; a first user traffic slot section associated with the first channel; and a second user traffic slot section associated with the second channel. 19. A network according to claim 18, wherein the multi-channel time division multiple access structure is an orthogonal domain multiple access structure. 20. A network according to claim 18, wherein the slot assignment protocol is unifying slot assignment protocol. 21. A network according to claim 18, further comprising a third channelized neighborhood including a second subset of the plurality of non-advantaged nodes assigned to a third channel. 22. A network according to claim 21, wherein the multi-channel time division multiple access structure further includes a third channelized bootstrap slot section for the third channel wherein the second channelized bootstrap section is offset in time from the first channelized bootstrap slot section and the third channelized bootstrap slot section.
