Method for confirming uplink semi-persistent scheduling deactivation and terminal device
Embodiments of the present disclosure relate to a method for confirming uplink semi-persistent scheduling deactivation and a terminal device. In example embodiments, an indication of uplink semi-persistent scheduling deactivation is received from a base station while the terminal device stores data available for uplink transmission. Then, confirmation of the deactivation is sent to the base station. Such confirmation of the deactivation may notify the base station that the terminal device has received the indication of the uplink semi-persistent scheduling deactivation and further that the uplink semi-persistent scheduling will be deactivated at the terminal device.
1. A method implemented in a terminal device, comprising:
receiving from a base station an indication of uplink semi-persistent scheduling deactivation;
sending to the base station a request for scheduling an uplink resource for the confirmation of the deactivation;
receiving from the base station the scheduled uplink resource; and
sending to the base station the confirmation of the deactivation, wherein the sending to the base station of the confirmation of the deactivation comprises:
using the scheduled uplink resource to send the confirmation; and
deactivating the semi-persistently scheduled uplink resource.
2. The method of claim 1 , further comprising:
obtaining an uplink resource from the received indication of uplink semi-persistent scheduling deactivation,
wherein the sending to the base station the confirmation of the deactivation comprises:
sending to the base station the confirmation of the deactivation using the obtained uplink resource.
3. The method of claim 2 , wherein the obtained uplink resource includes one physical resource block.
4. The method of claim 1 , wherein the sending to the base station the confirmation of the deactivation comprises:
sending to the base station the confirmation of the deactivation as a media access control control element.
5. The method of claim 4 , wherein the media access control control element is associated with a predefined media access control protocol data unit sub-header for identifying the confirmation of the deactivation.
6. A terminal device, comprising at least one processor and at least one non-transitory memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, to cause the terminal device to at least to:
receive from a base station an indication of uplink semi-persistent scheduling deactivation;
send to the base station a request for scheduling an uplink resource for the confirmation of the deactivation;
receive from the base station the scheduled uplink resource; and
send to the base station the confirmation of the deactivation, wherein the sending to the base station of the confirmation of the deactivation comprises:
using the scheduled uplink resource to send the confirmation, and
deactivating the semi-persistently scheduled uplink resource.
7. The terminal device of claim 6 , the at least one memory and the computer program code configured to, with the at least one processor, to further cause the terminal device to at least to:
obtain an uplink resource from the received indication of uplink semi-persistent scheduling deactivation,
send to the base station the confirmation of the deactivation using the obtained uplink resource.
8. The terminal device of claim 7 , wherein the obtained uplink resource includes one physical resource block.
9. The terminal device of claim 6 , the at least one memory and the computer program code configured to, with the at least one processor, to further cause the terminal device to at least to:
send to the base station the confirmation of the deactivation as a media access control control element.
10. The terminal device of claim 9 , wherein the media access control control element is associated with a predefined media access control protocol data unit sub-header for identifying the confirmation of the deactivation.
11. A computer program product being tangibly stored on a non-transitory computer readable storage medium and including instructions which, when executed with at least one processor, cause a terminal to perform at least the following:
receiving from a base station an indication of uplink semi-persistent scheduling deactivation;
sending to the base station a request for scheduling an uplink resource for the confirmation of the deactivation;
receiving from the base station the scheduled uplink resource; and
sending to the base station the confirmation of the deactivation, wherein the sending to the base station of the confirmation of the deactivation comprises:
using the scheduled uplink resource to send the confirmation; and
deactivating the semi-persistently scheduled uplink resource.
12. The computer program product of claim 11 , wherein the instructions further cause the terminal to perform at least the following:
obtaining an uplink resource from the received indication of uplink semi-persistent scheduling deactivation,
wherein the sending to the base station the confirmation of the deactivation comprises:
sending to the base station the confirmation of the deactivation using the obtained uplink resource.
13. The computer program product of claim 12 , wherein the obtained uplink resource includes one physical resource block.
14. The computer program product of claim 11 , wherein the sending to the base station the confirmation of the deactivation comprises:
sending to the base station the confirmation of the deactivation as a media access control control element.
