REQUEST SIGNAL DESIGNS FOR MULTIPLE SERVICE TYPES
First Claim
1. A method for conducting communications over a shared communication medium involving a plurality of nodes, the method comprising:
- (a) sending a request from a first node in the plurality of nodes, the shared communication medium organized to include a request signal space and a scheduled transmission signal space, the request signal space including a plurality of request segments each having a different location within the request signal space, the scheduled transmission signal space including a plurality of scheduled transmission segments each having a different location within the scheduled transmission signal space, the request sent in a request segment that is one of the plurality of request segments;
(b) obtaining an assignment associating the request with a scheduled transmission segment selected from the plurality of scheduled transmission segments, the assignment taking into account location of the request within the request signal space;
(c) from the first node, sending a data transmission in the scheduled transmission segment associated with the request in accordance with the assignment; and
(d) wherein the plurality of scheduled transmission segments include multiple categories of scheduled transmission segments associated with different service types.
