Abstract
A user equipment can be configured to evaluate a reference signal from a network node and determine channel state information comprising a format indicator, wherein the format indicator comprises a rank indicator and the channel state information spatial resolution type. The user equipment can transmit to the network node the channel state information, which can be decoded by a network node to determine transmission scheduling parameters to be transmitted to the user equipment.
Claims20
Network equipment, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- receiving, from a user equipment, channel state information feedback comprising a first portion comprising:
- a format indicator indicating a channel state information spatial domain resolution type representative of a spatial domain resolution type of channel state information, and
- a rank indicator indicating how many different data streams are used for transmissions between the network equipment and the user equipment;
- and
- decoding the channel state information feedback, resulting in decoded channel state information feedback, the decoding comprising:
- decoding the first portion of the channel state information feedback, resulting in a decoded format indicator, and
- using the decoded format indicator to decode a second portion of the channel state information feedback.
A method, comprising:
- determining, by a user equipment comprising a processor, channel state information based on a reference signal received from network equipment, the channel state information comprising:
- a format indicator comprising a channel state information spatial domain resolution type representative of a spatial domain resolution of the channel state information, and
- a rank indicator that indicates how many different transmission streams are used for transmissions between the network equipment and the user equipment;
- and
- transmitting, by the user equipment, channel state information feedback to the network equipment, wherein the channel state information feedback comprises a first portion comprising the format indicator, and a second portion comprising a remainder of the channel state information feedback other than the first portion, wherein the transmitting the channel state information feedback to the network equipment enables the network equipment to decode the second portion using a result obtained from decoding the first portion.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of network equipment, facilitate performance of operations, comprising:
- receiving, from a user equipment, channel state information feedback comprising a first portion of channel state information feedback comprising:
- a format indicator indicating a spatial domain resolution type representative of a spatial domain resolution of the channel state information, and
- a rank indicator representative of how many different transmission streams are used for transmissions between the network equipment and the user equipment;
- and
- decoding the channel state information feedback, resulting in decoded channel state information feedback, the decoding comprising:
- decoding the first portion of the channel state information feedback, resulting in a decoded format indicator, and
- using the decoded format indicator to decode a second portion of the channel state information feedback.
