Abstract
An enhanced linear combination codebook framework can support power allocation between transmission layers. Scaling between the layers of the codebook can be unequal so that power allocated between the layers can depend on the channel. For example, the network can configure the codebook to use radio resource control signaling to send codebook data to the UE.
Claims20
A method, comprising:
- configuring, by a wireless network device of a wireless network, a codebook of the wireless network used for transmissions, resulting in a configured codebook, wherein the configuring the codebook comprises facilitating an unequal scaling between transmission layers of the wireless network;
- transmitting, by the wireless network device, the configured codebook to a mobile device of the wireless network;
- and
- in response to the transmitting the configured codebook to the mobile device, receiving, by the wireless network device from the mobile device, precoding matrix index data indicative that the configured codebook has been utilized to generate channel state data, wherein the precoding matrix index data is based on flag data indicative of the unequal scaling between the transmission layers.

A method, comprising:
- receiving, by a mobile device comprising a processor from a wireless network device, a codebook usable for a transmission in a wireless network, wherein the codebook has been configured by the wireless network device to facilitate an unequal scaling between transmission layers of the wireless network;
- and
- in response to the receiving the codebook, transmitting, by the mobile device, precoding matrix index data to the wireless network device indicative that the codebook has been utilized by the mobile device to generate channel state data, wherein the precoding matrix index data is based on flag data representative of an unequal scaling between the transmission layers.
A mobile device, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- receiving codebook data associated with a codebook to be utilized by the mobile device for a transmission to a network device of a wireless network to which the mobile device is connected;
- in response to the receiving the codebook data, generating channel state data based on the codebook data, wherein the channel state data comprises precoding matrix index data;
- and
- in response to the generating the channel state data, transmitting the precoding matrix index data to the network device indicative that the codebook has been utilized by the mobile device to generate the channel state data, wherein the precoding matrix index data is based on flag data indicative of an uneven scaling between transmission layers of the wireless network.
