Abstract
A method of improving a hybrid automatic repeat request (HARQ) procedure in the transition of transmission time interval (TTI) bundling for a MAC layer of a user equipment in a wireless communication system, the method including activating TTI bundling upon receiving a bundling activation command, and using a first number of unused HARQ processes in the first round trip time after TTI bundling is activated to continue the first number of unfinished HARQ processes before TTI bundling is activated.
Claims22
A method of improving a hybrid automatic repeat request, abbreviated to HARQ, procedure in the transition of transmission time interval, abbreviated to TTI, bundling for a medium access control layer of a user equipment in a wireless communication system, the method comprising:
- activating TTI bundling upon receiving a bundling activation command;
- and
- using a first number of unused HARQ processes in the first round trip time (RTT) after TTI bundling is activated to continue the first number of unfinished HARQ processes before TTI bundling is activated.
A communication device of a wireless communication system for improving a hybrid automatic repeat request, abbreviated to HARQ, procedure in the transition of transmission time interval, abbreviated to TTI, bundling, the communication device comprising:
- means for activating TTI bundling upon receiving a bundling activation command;
- and
- means for using a first number of unused HARQ processes in the first round trip time (RTT) after TTI bundling is activated to continue the first number of unfinished HARQ processes before TTI bundling is activated.
A method of improving a hybrid automatic repeat request, abbreviated to HARQ, procedure in the transition of transmission time interval, abbreviated to TTI, bundling for a medium access control layer of a user equipment in a wireless communication system, the method comprising:
- deactivating TTI bundling upon receiving a bundling deactivation command;
- and
- using a first number of unused HARQ processes in the first round trip time (RTT) after TTI bundling is deactivated to continue the first number of unfinished HARQ processes before TTI bundling is deactivated.
A communication device of a wireless communication system for improving a hybrid automatic repeat request, abbreviated to HARQ, procedure in the transition of transmission time interval, abbreviated to TTI, bundling, the communication device comprising:
- means for deactivating TTI bundling upon receiving a bundling deactivation command;
- and
- means for using a first number of unused HARQ processes in the first round trip time (RTT) after TTI bundling is deactivated to continue the first number of unfinished HARQ processes before TTI bundling is deactivated.
A method of improving a hybrid automatic repeat request, abbreviated to HARQ, procedure in the transition of transmission time interval, abbreviated to TTI, bundling for a network in a wireless communication system, the method comprising:
- changing status of TTI bundling;
- and
- synchronizing with a user equipment connecting with the network for an uplink HARQ process when the user equipment uses a first number of unused HARQ processes in the first round trip time, after the status of TTI bundling is changed, to continue the first number of unfinished HARQ processes before the status of TTI bundling is changed.
A communication device of a wireless communication system for improving a hybrid automatic repeat request, abbreviated to HARQ, procedure in the transition of transmission time interval, abbreviated to TTI, bundling, the communication device comprising:
- means for changing status of TTI bundling;
- and
- means for synchronizing with a user equipment connecting with the communication device for an uplink HARQ process when the user equipment uses a first number of unused HARQ processes in the first round trip time (RTT) after the status of TTI bundling is changed to continue the first number of unfinished HARQ processes before the status of TTI bundling is changed.
A method of improving a hybrid automatic repeat request, abbreviated to HARQ, procedure in the transition of transmission time interval, abbreviated to TTI, bundling for a network in a wireless communication system, the method comprising:
- performing a plurality of HARQ processes;
- and
- sending a command for changing status of TTI bundling to a user equipment after each of the plurality of HARQ processes reaches the maximum number of HARQ retransmissions and is flushed from a HARQ buffer.
