Method and device for multi-carrier transmission in wireless communication

A base station for wireless communications, the base station comprising:

• a transceiver;
• and
• a processor, wherein the transceiver and the processor are configured to:
• transmit a first information block, wherein the first information block is used to determine a set of first-type cell sets,
• transmit a first signaling,
• wherein the first signaling comprises a first field used to determine a first indication value corresponding to a starting serving cell and a first quantity value, and wherein the starting serving cell is a serving cell comprised in the first cell set and a second cell set, and wherein any serving cell comprised in the second cell set belongs to the first cell set, with a number of serving cells comprised in the second cell set being equal to the first quantity value, and
• wherein the first signaling is used to determine a first cell set out of the first set of first-type cell sets, and wherein the first cell set comprises a plurality of serving cells,
• wherein the first cell set and the second cell set respectively correspond to schedulings of links in different directions, and wherein a second field comprised in the first signaling is used to determine a direction of a link scheduled by the first signaling.

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

• receiving a first information block;
• determining, based on the first information block, a first set of first-type cell sets;
• and
• receiving a first signaling comprising a first field and a second field;
• determining, based on the first signaling, a first cell set out of the first set of first-type cell sets, wherein the first cell set comprises a plurality of serving cells;
• determining, based on the first field, a starting serving cell from the first cell set and a number of serving cells in a second cell set;
• determining the second cell set based on the starting serving cell and the number of serving cells in the second cell set, wherein each serving cell in the second cell set belongs to the first cell, and wherein the first cell set and the second cell set respectively correspond to schedulings of links in different directions;
• and
• determining, based on the second field, a direction of a link scheduled by the first signaling.
