Embodiment Construction

[0031] The present invention relates to communication performed on a shared communication medium including a plurality of nodes. The present invention particularly relates to techniques used to allocate opportunities for transmission based on requests.

[0032] figure 1 A simplified network including a scheduler node 102 and a plurality of access nodes 104, 106, 108, and 110 using a shared communication medium according to an embodiment of the present invention is shown. This configuration corresponds to an operation mode referred to herein as "scheduling mode", which will be described as an illustrative example.

[0033] reference figure 1 , The scheduler node 102 is used to control the use of the shared communication medium by the access nodes 104, 106, 108, and 110. The shared communication medium may represent any communication medium used by more than one node. For example, a shared communication medium may represent signal space on one or more satellite channels. Therefore...

Abstract

Methods and apparatuses are presented for conducting communications over a shared communication medium involving (a) sending a request from a first node, 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 sentin a request segment, (b) obtaining an assignment associating the request with a scheduled transmission segment, and (c) from the first node, sending a data transmission in the scheduled transmissionsegment associated with the request in accordance with the request, and (d); wherein a collection of request segments in the plurality of request segments is separated by a guard zone from an adjacent collection of scheduled transmission segments in the plurality of scheduled transmission segments.
