Method and apparatus for semi-persistent scheduling in wireless communication

A base station used for wireless communication, the base station comprising:

• a transceiver;
• and
• a processor, wherein the transceiver and the processor are configured to:
• send a first information block used for configuring a first semi-persistent transmission, wherein the first semi-persistent transmission corresponds to a first codeword group comprising a first codeword and a second codeword;
• send a first signaling used for releasing scheduling corresponding to at least the second codeword in the first codeword group corresponding to the first semi-persistent transmission,
• wherein the first signaling comprises a first field set used for Physical Downlink Control Channel (PDCCH) validation of scheduling release corresponding to at least the second codeword in the first codeword group corresponding to the first semi-persistent transmission, and
• wherein the first field set is associated with the first codeword and the second codeword.

A method used in a user equipment (UE) for wireless communication, the method comprising:

• receiving a first information block used for configuring a first semi-persistent transmission, wherein the first semi-persistent transmission corresponds to a first codeword group comprising a first codeword and a second codeword;
• and
• receiving a first signaling used for releasing scheduling corresponding to at least the second codeword in the first codeword group corresponding to the first semi-persistent transmission,
• wherein the first signaling comprises a first field set used for Physical Downlink Control Channel (PDCCH) validation of scheduling release corresponding to at least the second codeword in the first codeword group corresponding to the first semi-persistent transmission, and
• wherein the first field set is associated with the first codeword and the second codeword.
