Abstract
A method and apparatus for handling a downlink control information indication for retransmission, the method receiving a downlink control information indication for retransmission of a hybrid automatic repeat request (HARQ) process; and if a transport block size in the downlink control information has changed compared with a transport block size associated with the HARQ process or a previous uplink grant for the HARQ process: handling the downlink control information indication for retransmission.
Claims6
A method comprising:
- receiving, at a user equipment, a downlink control information comprising an indication for retransmission of a hybrid automatic repeat request (HARQ) process, the downlink control information for a semi persistent scheduling (SPS) cell radio network temporary identifier (C-RNTI) for the user equipment or for a Temporary cell radio network temporary identifier (C-RNTI) for the user equipment;
- determining that a transport block size in the downlink control information has changed compared with a transport block size associated with the HARQ process or a previous uplink grant for the HARQ process;
- handling the indication for retransmission of the HARQ process by ignoring the transport block size in the downlink control information and utilizing the transport block size associated with the HARQ process or with the previous uplink grant for the HARQ process for the retransmission;
- and
- performing the retransmission.

A user equipment comprising:
- a processor;
- and
- a communications subsystem,
- wherein the user equipment is configured to:
- receive a downlink control information comprising an indication of retransmission of a hybrid automatic repeat request (HARQ) process, the downlink control information for a semi persistent scheduling (SPS) cell radio network temporary identifier (C-RNTI) for the user equipment or for a Temporary cell radio network temporary identifier (C-RNTI) for the user equipment;
- and
- determine that a transport block size in the downlink control information has changed compared with a transport block size associated with the HARQ process or with a previous uplink grant for the HARQ process;
- handle the indication for retransmission of the HARQ process by ignoring the transport block size in the downlink control information and utilizing the transport block size associated with the HARQ process or with the previous uplink grant for the HARQ process for the retransmission;
- and
- perform the retransmission.
