Abstract
System and method for Multi-User (MU) Multiple-Input-Multiple-Output (MIMO) transmission, the method including assigning to an originator station in a MU-MIMO wireless communication network, said originator station separate from a primary beamformer of the MU-MIMO communication network, permission for MU group management, and performing MU-MIMO transmission by the originator station to a plurality of stations in the MU-MIMO communication network.

A method for Multi-User (MU) Multiple-Input-Multiple-Output (MIMO) transmission, the method comprising:
- assigning permission for MU group management to an originator station having MU MIMO group management capabilities in a MU-MIMO wireless communication network, wherein said originator station is separated from a primary beamformer of the MU-MIMO communication network,
- wherein assigning said permission for MU group management comprises allocating to said originator station a dedicated plurality of Multi-User (MU) groups, and
- wherein the primary beamformer refrains from performing MU-MIMO transmission to the dedicated plurality of MU groups while the permission for MU-MIMO transmission is assigned to the originator station.
A method for Multi-User (MU) Multiple-Input-Multiple-Output (MIMO) transmission, the method comprising:
- assigning to an originator station in a MU-MIMO wireless communication network, said originator station separate from a primary beamformer of the MU-MIMO communication network, permission for MU group management,
- wherein assigning said permission for MU group management comprises allocating to said originator station a dedicated plurality of Multi-User (MU) groups, and
- wherein the primary beamformer refrains from performing MU-MIMO transmission to the dedicated plurality of MU groups while the permission for MU-MIMO transmission is assigned to the originator station, and wherein the primary beamformer continues to perform MU-MIMO transmission to MU groups excluding the dedicated plurality of MU groups.
A method for Multi-User (MU) Multiple-Input-Multiple-Output (MIMO) transmission, the method comprising:
- assigning to an originator station in a MU-MIMO wireless communication network, said originator station separate from a primary beamformer of the MU-MIMO communication network, permission for MU group management,
- wherein assigning said permission for MU group management comprises allocating to said originator station a dedicated plurality of Multi-User (MU) groups,
- wherein assigning said permission for MU-MIMO transmission comprises allocating to said originator station a first dedicated plurality of Multi-User (MU) groups, the method further comprising:
- assigning to at least one additional originator station in the MU-MIMO communication network, said additional originator station being separate from the primary beamformer, permission for MU-MIMO group management, wherein assigning said permission to said at least one additional originator station comprises allocating to each of said at least one additional originator station a corresponding dedicated plurality of Multi-User (MU) groups;
- and
- wherein the primary beamformer refrains from performing MU-MIMO transmission to the dedicated plurality of MU groups while the permission for MU-MIMO transmission is assigned to the at least one additional originator station, and wherein the primary beamformer continues to perform MU-MIMO transmission to MU groups excluding the dedicated plurality of MU groups.

A method for Multi-User (MU) Multiple-Input-Multiple-Output (MIMO) group management by a non-primary beamformer originator station of a MU-MIMO communication network having MU MIMO group management capabilities, the method comprising:
- receiving, at the non-primary beamformer originator station, notification of an assignment, from a primary beamformer of the MU-MIMO communication network, of permission for MU-MIMO group management by the non-primary beamformer originator station,
- wherein assigning said permission for MU group management comprises allocating to said originator station a dedicated plurality of Multi-User (MU) groups, and
- wherein the primary beamformer refrains from performing MU-MIMO transmission to the dedicated plurality of MU groups while the permission for MU-MIMO transmission is assigned to the originator station.
A method for Multi-User (MU) Multiple-Input-Multiple-Output (MIMO) group management by a non-primary beamformer originator station of a MU-MIMO communication network, the method comprising:
- receiving, at the non-primary beamformer originator station, notification of an assignment, from a primary beamformer of the MU-MIMO communication network, of permission for MU-MIMO group management by the non-primary beamformer originator station;
- and
- transmitting, a notification by the non-primary beamformer originator station to a plurality of stations in the MU-MIMO communication network, said notification informing the receiving stations of their MU group membership status and of the corresponding range of MU group indices that were allocated to the non-primary beamformer originator station.
A method for Multi-User (MU) Multiple-Input-Multiple-Output (MIMO) group management by a non-primary beamformer originator station of a MU-MIMO communication network, the method comprising:
- receiving, at the non-primary beamformer originator station, notification of an assignment, from a primary beamformer of the MU-MIMO communication network, of permission for MU-MIMO group management by the non-primary beamformer originator station;
- and
- transmitting a notification to the primary beamformer, said notification indicating that the non-primary beamformer originator station is no longer transmitting to a MU group that has been previously assigned to the non-primary beamformer originator station.
A primary beamformer comprising:
- a processor;
- and
- a computer usable medium connected to the processor, wherein the computer usable medium contains a set of instructions for performing a multiple-user multiple-input multiple-output (MU-MIMO) transmission in a MU-MIMO communication network, wherein the processor is designed to carry out a set of instructions to perform a method of:
- assigning to an originator station in a MU-MIMO wireless communication network having MU MIMO group management capabilities, said originator station being separated from the primary beamformer of the MU-MIMO communication network, permission for MU group management,
- wherein assigning said permission for MU group management comprises allocating to said originator station a dedicated plurality of Multi-User (MU) groups, and
- wherein the primary beamformer refrains from performing MU-MIMO transmission to the dedicated plurality of MU groups while the permission for MU-MIMO transmission is assigned to the originator station.
