Abstract
A method in a transmitting node in a wireless communication system for instructing a user terminal to perform uplink sounding is provided, said method comprising: generating an unlink grant in a downlink control information (DCI) for instructing the user terminal to transmit an uplink channel with only a reference signal; and transmitting the DCI with said uplink grant to the user terminal, and wherein said uplink grant is configured as a redundant state within the DCI. A method in a receiving node in a wireless communication system for performing uplink sounding is also provided.
Claims15
A method in a transmitting node in a wireless communication system for instructing a user terminal to perform uplink sounding, said method comprising:
- generating, by the transmitting node, an uplink grant in a downlink control information (DCI) for instructing the user terminal to transmit an uplink channel with only a reference signal;
- and
- transmitting, by the transmitting node, the DCI with the uplink grant to the user terminal, wherein:
- the uplink grant is configured as a redundant state within the DCI;
- and
- the redundant state is able to indicate the disabled transmission of data blocks and control signaling on the uplink.
A method in a receiving node in a wireless communication system for performing uplink sounding, said method comprising:
- receiving, by the receiving node, a downlink control information (DCI) with an uplink grant from the network node;
- and
- enabling, by the receiving node, the transmission of an uplink channel with only a reference signal to the network node based on the uplink grant,
- wherein:
- the uplink grant is configured as a redundant state within the DCI;
- and
- the redundant state is able to indicate the disabled transmission of all the data blocks and control signaling on the uplink.
A network node in a wireless communication system operative to instruct a user terminal to perform uplink sounding, comprising:
- a processing unit for generating an uplink grant in a downlink control information (DCI) for instructing the user terminal to transmit an uplink channel with only a reference signal;
- and
- a transmitting unit for transmitting the DCI with said uplink grant to the user terminal;
- wherein:
- the uplink grant is configured as a redundant state within the DCI;
- and
- the redundant state is able to indicate the disabled transmission of data blocks and control signaling on the uplink.
A user terminal in a wireless communication system operative to perform uplink sounding instructed by a network node, comprising:
- a receiving unit for receiving a downlink control information (DCI) with an uplink grant from the network node;
- and
- a processing unit for configuring the user terminal to transmit the uplink channel with only a reference signal according to the uplink grant,
- wherein:
- the uplink grant is configured as a redundant state within the DCI;
- the redundant state is able to indicate the disabled transmission of data blocks and control signaling on the uplink.
