Abstract
Allocating resources in a wireless network utilizing SU-MIMO and MU-MIMO modes of operation includes determining an increase in a resource usage of MU-MIMO wireless devices and responsive to the determining, reducing an allocation of resources for one or more SU-MIMO wireless devices. These operations may be performed based on determining that a load level associated with a serving access node rises to meet a threshold.
Claims20
A method for allocating resources in a wireless network, the method comprising:
- determining an increase in a resource usage of wireless devices participating in a multi-user MIMO mode of operation (MU-MIMO wireless devices);
- and
- responsive to the determining, reducing an allocation of resources for one or more wireless devices participating in a single-user MIMO mode of operation (SU-MIMO wireless devices),
- wherein the MU-MIMO wireless devices and the SU-MIMO wireless devices are attached to an access node configured to deploy a radio air interface with a plurality of resources.
A system for allocating resources in a wireless network, the system comprising:
- a processing node;
- and
- a processor coupled to the processing node, the processor being configured to:
- allocate a first default amount of resources to wireless devices attached to an access node and participating in a single-user MIMO mode of operation (SU-MIMO wireless devices);
- allocate a second default amount of resources to wireless devices attached to the access node and participating in a multi-user MIMO mode of operation (MU-MIMO wireless devices);
- responsive to determining an increase in a resource requirement of the MU-MIMO wireless devices, allocating a first reduced amount of resources towards the SU-MIMO wireless devices;
- and
- responsive to determining the increase in the resource requirement of the MU-MIMO wireless devices, allocating a first increased amount of resources towards the MU-MIMO wireless devices.
A processing node for allocating resources in a wireless network, the processing node being configured to perform operations comprising:
- determining that a load level associated with an access node rises to meet a threshold;
- responsive to determining that the load level rises to meet the threshold, monitoring resource usage of wireless devices attached to the access node and participating in a multi-user MIMO mode of operation (MU-MIMO wireless devices);
- and
- responsive to determining an increase in the resource usage of the MU-MIMO wireless devices, increasing a first allocation of resources towards the MU-MIMO wireless devices.
