Abstract
There is provided a method performed by a user equipment (UE) configured with a number of transmit antenna ports (NTX). The method comprises: transmitting an indication of a number of transmit antenna port groups to a network node, wherein each transmit port group comprises one or more of the configured transmit antenna ports; and receiving an indication of a configuration for transmitting data to the network node, the configuration based on the number of transmit antenna port groups.
Claims14
A method performed by a User Equipment (UE) configured with a number of transmit antenna ports (NTX), the method comprising:
- transmitting an indication of a number of transmit antenna port groups to a network node, wherein each transmit antenna port group comprises one or more of the configured transmit antenna ports and wherein the number of transmit antenna port groups is 8, which indicates that the UE is non-coherent, when NTX is 8;
- and
- receiving an indication of a configuration for transmitting data to the network node, the configuration based on the number of transmit antenna port groups, wherein the method further comprises associating a group of sounding reference signal (SRS) ports to a transmit antenna port group, based on an ordering of a SRS port within an SRS resource set, the ordering of the SRS port being based on a SRS port number.
A method performed by a network node, the method comprising:
- receiving an indication of a number of transmit antenna port groups from a User Equipment (UE) configured with a number of transmit antenna ports (NTX), wherein the number of transmit antenna port groups is 8, which indicates that the UB is non-coherent, when NTX is 8 and wherein a group of sounding reference signal (SRS) ports are associated with a transmit antenna port group, based on an ordering of a SRS port within an SRS resource set, the ordering of the SRS port being based on a SRS port number;
- and
- determining a configuration for the UE to transmit data, the configuration determined based on the indication of the number of transmit antenna port groups;
- and
- transmitting an indication of the determined configuration to the UE.
A User Equipment (UE) comprising processing circuitry and a network interface connected thereto, the processing circuitry configured to:
- transmit an indication of a number of transmit antenna port groups to a network node, wherein each transmit antenna port group comprises one or more of the configured transmit antenna ports, wherein the number of transmit antenna port groups is 8, which indicates that the UE is non-coherent, when NTX is 8;
- and
- receive an indication of a configuration for transmitting data to the network node, the configuration based on the number of transmit antenna port groups, wherein the method further comprises associating a group of sounding reference signal (SRS) ports to a transmit antenna port group, based on an ordering of a SRS port within an SRS resource set, the ordering of the SRS port being based on a SRS port number.
