Abstract
The present invention relates to a controller, an access node, an aggregation node and methods thereof in a radio communication network. The controller comprises: a processor configured to select a plurality of spreading codes that are non-orthogonal or short orthogonal, and a transmitter coupled with the processor. The transmitter is configured to notify at least one of an access node or an aggregation node of the plurality of spreading codes.
Claims13
A controller in a radio communication network, the controller comprising:
- a processor configured to select a plurality of spreading codes that are non-orthogonal or short orthogonal, and
- a transmitter coupled with the processor, wherein the transmitter is configured to notify at least one of an access node or an aggregation node of the plurality of spreading codes.
An access node in a radio communication network, comprising:
- at least one first receive antenna configured to receive a plurality of physical signals from one or more user nodes;
- a processor coupled with the at least one first receive antenna, wherein the processor is configured to:
- spread the plurality of physical signals with a plurality of spreading codes, wherein the plurality of spreading codes are non-orthogonal or short orthogonal;
- and
- compose the plurality of spread signals to generate a first composite signal;
- and
- at least one first transmit antenna coupled with the processor, wherein the at least one first transmit antenna is configured to transmit the first composite signal to an aggregation node.
An aggregation node in a radio communication network, comprising:
- a receive antenna configured to receive a first composite signal from an access node, and
- a processor coupled with the receive antenna, wherein the processor is configured to despread and decompose the first composite signal using a plurality of spreading codes to obtain a plurality of despread signals, wherein the plurality of spreading codes are non-orthogonal or short orthogonal.
