Abstract
A method, system and computer program for transmitting at least two payloads in a downstream traffic phase of a time-division duplex (TDD) cycle with a single preamble from a headend followed by concatenated payloads without intervening preambles, whereby the payloads are ranked by increasing modulation profiles. The preamble, and concatenated and ordered set of payloads are then transmitted to two or more predetermined customer premise equipments (CPEs).
Claims20
A method comprising:
- receiving a preamble of a message, wherein:
- the message comprises a plurality of payloads following the preamble,
- the plurality of payloads are arranged in an order of increasing modulation profile, and
- there is no intervening preamble between adjacent payloads of the plurality of payloads;
- identifying a payload of the plurality of payloads;
- determining, according to the preamble, how to properly receive the identified payload;
- and
- receiving the identified payload.

A method, comprising:
- receiving a first message identifying a payload of a plurality of payloads;
- receiving a second message comprising:
- a preamble, and
- a plurality of payloads following the preamble, wherein the plurality of payloads comprise the identified payload and are arranged in an order of increasing modulation profile;
- determining, based at least in part on the preamble, how to properly decode the identified payload;
- and
- decoding the identified payload.

A method, comprising:
- receiving a message from a transmitting node, the message comprising:
- a preamble, and
- a plurality of payloads following the preamble, wherein the plurality of payloads are arranged in an order based on distance from the transmitting node and there is no intervening preamble between adjacent ones of the plurality of payloads;
- identifying a payload of the plurality of payloads;
- determining, based at least in part on the preamble, how to properly receive the identified payload;
- and
- receiving the identified payload.
