Method, network device and terminal device for semi-persistent scheduling

A method for Semi-Persistent Scheduling (SPS), comprising:

• receiving, from a network device, at least one uplink (UL) configuration message to activate or deactivate a configured UL grant in at least one cell among one or more cells configured to a terminal device;
• and
• sending, to the network device, a first confirmation message for confirmation of the at least one UL configuration message,
• wherein the first confirmation message comprises an indicator to confirm the at least one UL configuration message, and the indicator comprises a bitmap wherein there is a correspondence between the at least one UL configuration message and one or more SPS configuration indexes, and wherein the one or more SPS configuration indexes is corresponding to a position in the bitmap.

A network device, comprising:

• a processor;
• and
• a memory, the memory containing instructions executable by the processor, whereby the network device is operative to:
• send, to a terminal device, at least one uplink (UL) configuration message to activate or deactivate a UL grant in at least one cell among one or more cells configured to the terminal device;
• and
• receive, from the terminal device, a first confirmation message for confirmation of the at least one UL configuration message,
• wherein the first confirmation message comprises an indicator to confirm the at least one UL SPS configuration message, and the indicator comprises a bitmap wherein there is a correspondence between the at least one UL configuration message and one or more Semi-Persistent Scheduling (SPS) configuration indexes, and wherein the one or more SPS configuration indexes is corresponding to a position in the bitmap.

A terminal device, comprising:

• a processor;
• and
• a memory, the memory containing instructions executable by the processor, whereby the terminal device is operative to:
• receive, from a network device, at least one uplink (UL) configuration message to activate or deactivate a UL grant in at least one cell among one or more cells configured to a terminal device;
• and
• send, to the network device, a first confirmation message for confirmation of the at least one UL configuration message,
• wherein the first confirmation message comprises an indicator to confirm the at least one UL configuration message, and the indicator comprises a bitmap wherein there is a correspondence between the at least one UL configuration message and one or more Semi-Persistent Scheduling (SPS) configuration indexes, and wherein the one or more SPS configuration indexes is corresponding to a position in the bitmap.
