Abstract
Disclosed are methods apparatuses and computer readable media. In one aspect, a method includes receiving a rank indication or a first index associated with the rank indication, wherein the rank indication is used to determine G rank values, wherein G is a positive integer, and receiving a matrix indication or a second index associated with the matrix indication, wherein the matrix indication is used to determine a basic matrix. The method further includes determining a precoding matrix for a transmission according to at least one of the G rank values or the basic matrix.

A method of wireless communication comprising:
- receiving, by a wireless device from a network node, a rank indication or a first index associated with the rank indication, wherein the rank indication is used to determine G rank values, wherein G is a positive integer greater than or equal to 2;
- determining, by the wireless device, G port groups corresponding to the G rank values, wherein each of the G rank values corresponds to a port group of the G port groups;
- receiving, by the wireless device from the network node, a matrix indication or a second index associated with the matrix indication, wherein the matrix indication is used to determine a basic matrix, wherein a size of the basic matrix is equal to a number of antenna ports divided by G;
- and
- determining, by the wireless device, a precoding matrix for a transmission according to at least one of the G rank values or the basic matrix.
A method of wireless communication comprising:
- transmitting, by a network node to a wireless device, a rank indication or a first index associated with the rank indication, wherein the rank indication is used to determine G rank values, wherein G is a positive integer greater than or equal to 2, and wherein each of the G rank values corresponds to a port group of G port groups;
- and
- transmitting, by the network node to the wireless device, a matrix indication or a second index associated with the matrix indication, wherein the matrix indication is used to determine a basic matrix, wherein a size of the basic matrix is equal to a number of antenna ports divided by G, and wherein the transmitting the rank indication or the first index associated with the rank indication and the transmitting the matrix indication or the second index associated with the matrix indication enable the wireless device to determine a precoding matrix for a transmission of data.
An apparatus for wireless communication comprising at least one processor and a memory storing instructions, execution of which by the processor causes the apparatus to:
- receive a rank indication or a first index associated with the rank indication, wherein the rank indication is used to determine G rank values, wherein G is a positive integer greater than or equal to 2;
- determine G port groups corresponding to the G rank values, wherein each of the G rank values corresponds to a port group of the G port groups;
- receive a matrix indication or a second index associated with the matrix indication, wherein the matrix indication is used to determine a basic matrix, and wherein a size of the basic matrix is equal to a number of antenna ports divided by G;
- and
- determine a precoding matrix for a transmission according to at least one of the G rank values or the basic matrix.
An apparatus for wireless communication comprising at least one processor and a memory storing instructions, execution of which by the at least one processor causes the apparatus to:
