Abstract
The use of traffic flag symbols allows a large number of CPEs to transmit traffic notifications to a network controller. In some such embodiments, hundreds of CPEs simultaneously transmit traffic flags on different subcarriers of a channel. For example, in a MoCA2 based access network, up to 480 CPEs can transmit flags in only 5 μs in the 100 MHz-wide channel.
Claims25
A network node, comprising:
- a receiver configured to receive an indication of an assigned subcarrier from a network controller;
- and
- a transmitter configured to transmit a traffic symbol on the assigned subcarrier, wherein the traffic symbol comprises a traffic flag that indicates whether the network node has upstream traffic to send to the network controller, the traffic flag being transmitted simultaneously with another traffic flag on another assigned subcarrier, and wherein the network controller schedules a reservation request based on the traffic flag, and wherein the traffic flag indicates a number of symbols requested to be scheduled.
A network node, comprising:
- a receiver configured to receive an indication of an assigned subcarrier from a network controller;
- and
- a transmitter configured to transmit a traffic symbol on the assigned subcarrier, wherein the traffic symbol comprises a traffic flag that indicates whether the network node has upstream traffic to send to the network controller, the traffic flag being transmitted simultaneously with another traffic flag on another assigned subcarrier, and wherein the traffic flag indicates a buffer fullness, wherein the traffic flag indicates a number of symbols requested to be scheduled.
