Abstract
A method implemented by an access node includes transmitting, by the access node to a user equipment (UE), a control information message scheduling a physical downlink shared channel (PDSCH), the control information message comprising at least one parameter for the PDSCH and a sounding reference signal (SRS) request field; receiving, by the access node from the UE, a SRS transmission in accordance with the at least one parameter for the PDSCH and the SRS request field transmitted in the control information message; and transmitting, by the access node to the UE, the scheduled PDSCH in accordance with the at least one parameter for the PDSCH transmitted in the control information message.
Claims20
A method, comprising:
- transmitting, by an access node to a user equipment (UE), a control information message scheduling a physical downlink shared channel (PDSCH), the control information message comprising at least one parameter for both the PDSCH and a sounding reference signal (SRS) request field;
- receiving, by the access node from the UE, an SRS transmission in accordance with the at least one parameter for both the PDSCH and the SRS request field in the control information message;
- and
- transmitting, by the access node to the UE, the PDSCH in accordance with the at least one parameter.
A method, comprising:
- receiving, by a user equipment (UE) from an access node, a control information message scheduling a physical downlink shared channel (PDSCH), the control information message comprising at least one parameter for both the PDSCH and a sounding reference signal (SRS) request field;
- transmitting, by the UE to the access node, an SRS transmission in accordance with the at least one parameter for both the PDSCH and the SRS request field in the control information message;
- and
- receiving, by the UE from the access node, the PDSCH in accordance with the at least one parameter.
An access node, comprising:
- one or more processors;
- and
- a non-transitory memory storage storing instructions that, when executed by the one or more processors, cause the access node to perform operations including:
- transmitting, to a user equipment (UE), a control information message scheduling a physical downlink shared channel (PDSCH), the control information message comprising at least one parameter for both the PDSCH and a sounding reference signal (SRS) request field;
- receiving, from the UE, an SRS transmission in accordance with the at least one parameter for both the PDSCH and the SRS request field in the control information message;
- and
- transmitting, to the UE, the PDSCH in accordance with the at least one parameter.
A user equipment (UE), comprising:

- receiving, from an access node, a control information message scheduling a physical downlink shared channel (PDSCH), the control information message comprising at least one parameter for both the PDSCH and a sounding reference signal (SRS) request field;
- transmitting, to the access node, an SRS transmission in accordance with the at least one parameter for both the PDSCH and the SRS request field in the control information message;
- receiving, from the access node, the PDSCH in accordance with the at least one parameter;
- and
- processing data in the PDSCH.
