Abstract
A method and apparatus are disclosed to handle TTI bundling. In an embodiment implemented in a UE (User Equipment), the method includes configuring the UE with a plurality of serving cells, wherein the TTI bundling and secondary cells with configured UL (uplink) could be simultaneously configured for the UE. In an embodiment from the perspective of a network, the method includes issuing, from a E-UTRAN (Evolved Universal Terrestrial Radio Access Network), a message to configure a UE with a plurality of serving cells, wherein the E-UTRAN could simultaneously configure the TTI bundling and the secondary cells with configured UL for the UE.
Claims12
A method to handle TTI (Transmission Time Interval) bundling, comprising:
- configured, for a UE (User Equipment), with a plurality of serving cells,
- wherein if the configured serving cells with configured uplink (UL) are configured or scheduled by different eNBs, the TTI bundling and secondary cells with configured UL (uplink) are allowed to be simultaneously configured for the UE, and
- wherein the TTI bundling and the secondary cells with configured UL are not simultaneously configured for the UE if the UE has sufficient configuration information to know that the configured serving cells with configured UL are configured or scheduled by a same eNB, or if the UE has no configuration information to know whether the configured serving cells with configured UL are configured or scheduled by different eNBs or not.
A communication device to handle TTI (Transmission Time Interval) bundling, the communication device comprising:
- a control circuit;
- a processor installed in the control circuit;
- a memory installed in the control circuit and operatively coupled to the processor;
- wherein the processor is configured to execute a program code stored in the memory to:
- configure a UE (User Equipment) with a plurality of serving cells,
- wherein if the configured serving cells with configured uplink (UL) are configured or scheduled by different eNBs, the TTI bundling and secondary cells with configured UL (uplink) are allowed to be simultaneously configured for the UE, and
- wherein the TTI bundling and the secondary cells with configured UL are not simultaneously configured for the UE if the UE has sufficient configuration information to know that the configured serving cells with configured UL are configured or scheduled by a same eNB, or if the UE has no configuration information to know whether the configured serving cells with configured UL are configured or scheduled by different eNBs or not.
