Abstract
Channel state information (CSI) can be transmitted to a network node incrementally to increase network efficiency. The CSI feedback framework can be enhanced by allowing a user equipment (UE) to report multiple sets of CSI feedback, where each set can comprise a rank indicator (RI), a pre-coder matrix indicator (PMI), and a channel quality indicator (CQI). Since a different set may have a different sub-band, the CSI feedback framework can support the sub-band rank, wherein rank data from a wideband and the sub-band can be used by the network.
Claims20
A method, comprising:
- based on a first defined rank indicator associated with a first transmission layer, receiving, by a network device comprising a processor, channel state data from a wireless device of a wireless network;
- based on second defined rank indicator associated with a second transmission layer, receiving, by the network device, incremental channel state data, different from the channel state data, from the wireless device;
- and
- based on a portion of the channel state data not comprised in the incremental channel state data and further based on the incremental channel state data, allocating, by the network device, a resource for the wireless device.
A system, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- receiving, from a mobile device, first channel state data representative of a first channel state of a first layer of a wireless network associated with a first frequency range;
- receiving, from the mobile device, second channel state data, different than the first channel state data, representative of a second channel state of a second layer, different than the first layer, of the wireless network associated with a second frequency range;
- and
- based on at least a portion of the first channel state data and the second channel state data from the mobile device, assigning a resource to the mobile device.
A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
- facilitating sending, by a mobile device to a network device, first rank data representative of a first rank associated with a first transmission layer of a wireless network;
- facilitating sending, by the mobile device to the network device, second rank data representative of a second rank associated with a second transmission layer of the wireless network, wherein the second rank data is incremental information to the first rank data;
- and
- in response to the facilitating the sending of the first rank data and the second rank data, receiving, by the mobile device from the network device, an allocation to use a network resource of the wireless network.
