Abstract
A method for handling an uplink grant received on a physical downlink control channel (PDCCH) in a user equipment (UE) of a wireless communication system is disclosed. The method includes steps of setting a Temporary Cell Radio Network Temporary Identifier (Temporary C-RNTI) of the UE to a value assigned in a Random Access Response message, monitoring a contention resolution message, receiving an uplink grant on PDCCH addressed to the Temporary C-RNTI, and not using the uplink grant to transmit data if the uplink grant corresponds to a Hybrid Automatic Repeat Request (HARQ) Process different from an HARQ Process used for transmission of a MediumAccess Control (MAC) Protocol Data Unit (PDU) in a Message 3 buffer.

A method for handling an uplink grant received on a physical downlink control channel (PDCCH) in a user equipment (UE) of a wireless communication system, the method comprising:
- setting a Temporary Cell Radio Network Temporary Identifier (Temporary C-RNTI) of the UE to a value assigned in a Random Access Response message;
- monitoring a Contention Resolution message;
- receiving a second uplink grant on PDCCH addressed to the Temporary C-RNTI;
- and
- not using the second uplink grant to transmit data when a Transport Block (TB) size indicated by the second uplink grant is different from that indicated by a first uplink grant provided in the Random Access Response message for the UE.
A communication device for handling an uplink grant received on a physical downlink control channel (PDCCH) in a user equipment (UE) of a wireless communication system, the communication device comprising:
- a processor for executing a program;
- and
- a memory coupled to the processor for storing the program;
- wherein the program comprises:
- setting a Temporary Cell Radio Network Temporary Identifier (Temporary C-RNTI) of UE to a value assigned in a Random Access Response message;
- monitoring a Contention Resolution message;
- receiving a second uplink grant on PDCCH addressed to the Temporary C-RNTI;
- and
- not using the second uplink grant to transmit data when a Transport Block (TB) size indicated by the second uplink grant is different from that indicated by a first uplink grant provided in the Random Access Response message for the UE.
