Abstract
The disclosure provides a method in a wireless network for link adaptation. The method comprises transmitting a first grant message indicating grant resources for a first link path to a first user equipment, UE; monitoring the grant resources for the first link path to determine whether data is transmitted from the first UE on the first link path; and inhibiting link adaptation for the grant resources for the first link path if no data is transmitted from the first UE on the first link path. The disclosure also provides a network node and a user equipment for link adaptation.
Claims15
A method in a wireless network for link adaptation, the method comprising:
- transmitting a first grant message indicating grant resources for a first link path to a first user equipment, UE;
- monitoring the grant resources for the first link path to determine whether data is transmitted from the first UE on the first link path;
- and
- inhibiting link adaptation for the grant resources for the first link path if no data is transmitted from the first UE on the first link path.
A method in a wireless network for link adaptation, the method comprising:
- receiving a second grant message allowing data transmission on a second link path in grant resources for a first link path from a network node;
- monitoring the grant resources for the first link path to determine whether data is transmitted on the second link path;
- and
- transmitting an ACK/NACK message to the network node if data is transmitted on the second link path in the grant resources for the first link path;
- wherein no ACK/NACK message will be sent to the network node if no data is transmitted on the second link path in the grant resources for the first link path.
(canceled)
A network node in a wireless network for link adaptation, the network node comprising:
- a transmitting unit configured to transmit a first grant message indicating grant resources for a first link path to a first user equipment, UE;
- a monitoring unit configured to monitor the grant resources for the first link path to determine whether data is transmitted from the first UE on the first link path;
- and
- a processing unit configured to inhibit link adaptation for the grant resources for the first link path if no data is transmitted from the first UE on the first link path.
A user equipment, UE, the UE comprising:
- a receiving unit configured to receive a second grant message allowing data transmission on a second link path in grant resources for a first link path from a network node;
- a monitoring unit configured to monitor the grant resources for the first link path to determine whether data is transmitted on the second link path;
- and
- a transmitting unit configured to transmit an ACK/NACK message to the network node if data is transmitted on the second link path in the grant resources for the first link path, and not to transmit ACK/NACK message to the network node if no data is transmitted on the second link path in the grant resources for the first link path.
