Abstract
Multiple wireless user devices act cooperatively to communicate with a remote destination node through a MIMO channel. In at least one embodiment, a cooperative cluster of user devices is formed that makes use of vertical coding techniques to achieve enhanced communication performance.
Claims21
A method for use with a wireless user device, comprising:
- joining a cooperative cluster of wireless user devices, said wireless user devices of said cooperative cluster to act cooperatively to communicate with a remote destination node through a multiple input, multiple output (MIMO) channel;
- transferring a first data message to each other wireless user device in said cooperative cluster, said first data message to be transmitted by said cooperative cluster to said remote destination node;
- obtaining at least one other data message from one or more other wireless user devices in said cooperative cluster, said at least one other data message to be transmitted by said cooperative cluster to said remote destination node;
- merging said first data message and said at least one other data message to form a merged bit stream;
- time-frequency coding said merged bit stream using a predetermined time-frequency code and performing interleaving to form a coded bit stream;
- and
- splitting said coded bit stream into multiple portions, said multiple portions including a first portion and at least one other portion.
4 more elements
A wireless apparatus, comprising:
- a bit stream merger to merge a bit stream of the wireless apparatus with at least one bit stream associated with another device in a common cooperative cluster as the wireless apparatus to form a merged bit stream, wherein said bit stream of said wireless apparatus and said at least one bit stream are to be transmitted to a remote destination device by the cooperative cluster, via a MIMO channel;
- a time-frequency coder and interleaver to time-frequency code and interleave said merged bit stream to generate a coded bit stream;
- a splitter to split said coded bit stream into multiple portions, said multiple portions including a first portion and at least one other portion;
- and
- a symbol mapper to map said first portion of said coded bit stream to symbols;
- and
- an RF transmitter to transmit said symbols into said MIMO channel.

An article comprising a storage medium having instructions stored thereon that, when executed by a computing platform, operate to:
- transfer a first data message from a first wireless user device in a cooperative cluster to each other wireless user device in said cooperative cluster, wherein said wireless user devices of said cooperative cluster are to act cooperatively to communicate with a remote destination node through a multiple input, multiple output (MIMO) channel, said first data message to be transmitted by said cooperative cluster to said remote destination node;
- obtain at least one other data message from one or more other wireless user devices in said cooperative cluster, said at least one other data message to be transmitted by said cooperative cluster to said remote destination node;
- merge said first data message and said at least one other data message to form a merged bit stream;
- time-frequency code said merged bit stream using a predetermined time-frequency code and perform interleaving to form a coded bit stream;
- and
- split said coded bit stream into multiple portions, said multiple portions including a first portion and at least one other portion.
3 more elements
A wireless system comprising:
- at least one dipole antenna;
- a bit stream merger to merge a bit stream of the wireless system with at least one bit stream associated with another device in a common cooperative cluster as the wireless system to form a merged bit stream, wherein said bit stream of said wireless system and said at least one bit stream are to be transmitted to a remote destination device by the cooperative cluster, via a MIMO channel;
- a time-frequency coder and interleaver to time-frequency code and interleave said merged bit stream to generate a coded bit stream;
- a splitter to split said coded bit stream into multiple portions, said multiple portions including a first portion and at least one other portion;
- and
- a symbol mapper to map said first portion of said coded bit stream to symbols;
- and
- an RF transmitter, coupled to said at least one dipole antenna, to transmit said symbols into said MIMO channel using said at least one dipole antenna.
