Abstract
This disclosure is directed to methods, systems, and devices related to wireless communication, and more specifically, to support high capability user equipment and to improve uplink A method of wireless communication, comprising receiving, by a wireless communication device, from a network device, a configuration of a sounding reference signal (SRS) resource with a plurality of ports or port groups; determining, by the wireless communication device, a parameter for an SRS port or an SRS port group of the SRS resource; and wherein the parameter comprises at least one of: one or more symbols, a comb offset, or a cyclic shift (CS) offset.
Claims28
A method for wireless communication, comprising:
- receiving, by a wireless communication device from a network device, a configuration of a sounding reference signal (SRS) resource,
- wherein the configuration comprises a parameter indicating ports configured for the SRS resource,
- wherein the ports configured for the SRS resource are grouped into SRS port groups;
- and
- determining, by the wireless communication device, a transmit power for an SRS transmission based on a time division multiplexing (TDM) factor and a number of ports in a symbol that are associated with the SRS resource,
- wherein the TDM factor is based on the parameter indicating the number of ports configured for the SRS resource, and
- wherein the transmit power is equally split across the number of ports in a symbol that are associated with the SRS resource.
A method for wireless communication, comprising:
- transmitting, by a network device, a configuration of a sounding reference signal (SRS) resource to a wireless communication device,
- wherein the configuration comprises a parameter indicating ports configured for the SRS resource,
- wherein the ports configured for the SRS resource are grouped into SRS port groups,
- wherein the configuration of the SRS resource enables the wireless communication device to determine a transmit power for an SRS transmission based on a time division multiplexing (TDM) factor and a number of ports in a symbol that are associated with the SRS resource, wherein the TDM factor is based on the parameter indicating the number of ports configured for the SRS resource, and wherein the transmit power is equally split across the number of ports in a symbol that are associated with the SRS resource.
A device for wireless communication, comprising processor electronics, one or more memories and transceiver electronics, wherein the processor electronics is configured to read instructions from the one or more memories and cause the device to:
- receiving, from a network device, a configuration of a sounding reference signal (SRS) resource,
- wherein the configuration comprises a parameter indicating ports configured for the SRS resource,
- wherein the ports configured for the SRS resource are grouped into SRS port groups;
- and
- determine a transmit power for an SRS transmission based on a time division multiplexing (TDM) factor and a number of ports in a symbol that are associated with the SRS resource,
- wherein the TDM factor is based on the parameter indicating the number of ports configured for the SRS resource, and
- wherein the transmit power is equally split across the number of ports in a symbol that are associated with the SRS resource.
A device for wireless communication, comprising processor electronics, one or more memories and transceiver electronics, wherein the processor electronics is configured to read instructions from the one or more memories and cause the device to:
- transmitting, by a network device, a configuration of a sounding reference signal (SRS) resource,
- wherein the configuration comprises a parameter indicating ports configured for the SRS resource,
- wherein the ports configured for the SRS resource are grouped into SRS port groups,
- wherein the configuration of the SRS resource enables the wireless communication device to determine a transmit power for an SRS transmission based on a time division multiplexing (TDM) factor and a number of ports in a symbol that are associated with the SRS resource, wherein the TDM factor is based on the parameter indicating the number of ports configured for the SRS resource, and wherein the transmit power is equally split across the number of ports in a symbol that are associated with the SRS resource.
