Problems solved by technology

It is difficult to provide a schedule that will integrate information from the network management gateway within 1 ms, since communication delays between the base station and any node in the core network often require single-digit millisecond delays or more
Reducing latency is expensive as it requires, for example, expensive high-speed fiber optic backhaul connections for each node

Embodiment Construction

[0022] Ad hoc networks, mesh networks, and multi-hop networks pose problems for centralized scheduling and access control methods. In general, a medium access control protocol in an ad hoc network must solve two problems, namely: the "hidden terminal problem" or the "hidden node problem", where a node is visible to an access point but not to others communicating with the access point. Nodes are not visible; and the "exposed endpoint problem", where a node is blocked from transmitting because it incorrectly concludes, via carrier sense, that its transmissions will be detected as an interferer by an exposed endpoint node.

[0023] Deterministic access schemes, on the other hand, establish schedules for individual nodes or links such that transmissions from nodes or on links are collision-free in the coding, time, frequency, or spatial division of the channel. The scheduling for conflict-free channel access can be established based on the topology of the network, or can be indepe...

Abstract

A method for scheduling resources in a network where the scheduling activity is split across two nodes in the network is disclosed, comprising: receiving, from a local scheduler in a first radio access network, access network information at a global scheduler; accessing information regarding a second radio access network allocating, at the global scheduler, resources for secondary allocation by the local scheduler; applying a hash function to map the allocated resources for secondary allocation to a set of hash values; and sending, from the global scheduler, the set of hash values to the localscheduler.
