Abstract

The present disclosure discloses a method and device in a wireless communication system, the method including: receiving configuration information for configuring multiple cells for a terminal device; and determining a reference cell for a first symbol according to a tenth cell from the multiple cells, or determining the reference cell for the first symbol according to a cell other than the tenth cell from the multiple cells, wherein the first symbol is configured as uplink in the tenth cell and at least one frequency-domain resource in the tenth cell is for a downlink transmission; or the first symbol is configured as downlink in the tenth cell and at least one frequency-domain resource in the tenth cell is for uplink transmission. The present disclosure improves the flexibility and reliability of the wireless communication system.

Claims (40)

1 . A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

receiving, from a base station, configuration information configuring multiple cells in a band for the UE; and

determining a reference cell for a first symbol according to at least one cell from the multiple cells,

wherein, in case that the first symbol is configured for an uplink transmission in the at least one cell, the at least one cell includes at least one frequency-domain resource allocated for a downlink reception,

wherein the reference cell is identified as a cell with a smallest cell identifier (ID) among the at least one cell, and

wherein the reference cell is associated with a directional collision within each cell.

2 . The method of claim 1 , in case that the first symbol is configured for the downlink reception in the at least one cell, the at least one cell includes at least one frequency-domain resource allocated for the uplink transmission.

3 . The method of claim 1 , wherein the reference cell for the first symbol is determined based on another cell different from the at least one cell among the multiple cells.

4 . The method of claim 1 , wherein a time-domain resource corresponding to the at least one frequency-domain resource includes the first symbol.

5 . A method performed by a base station in a wireless communication system, the method comprising:

transmitting, to a user equipment (UE), configuration information configuring multiple cells in a band for the UE,

wherein at least one cell from the multiple cells is used to determine a reference cell for a first symbol,

wherein, in case that the first symbol is configured for an uplink reception in the at least one cell, the at least one cell includes at least one frequency-domain resource allocated for a downlink transmission,

wherein the reference cell is identified as a cell with a smallest cell identifier (ID) among the at least one cell, and

wherein the reference cell is associated with a directional collision within each cell.

6 . The method of claim 5 , in case that the first symbol is configured for the downlink transmission in the at least one cell, the at least one cell includes at least one frequency-domain resource allocated for the uplink reception.

7 . The method of claim 5 , wherein the reference cell for the first symbol is determined based on another cell different from the at least one cell among the multiple cells.

8 . The method of claim 5 , wherein a time-domain resource corresponding to the at least one frequency-domain resource includes the first symbol.

9 . A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver; and

a controller coupled with the transceiver, and configured to:

receive, from a base station, configuration information configuring multiple cells in a band for the UE, and

determine a reference cell for a first symbol according to at least one cell from the multiple cells,

wherein, in case that the first symbol is configured for an uplink transmission in the at least one cell, the at least one cell includes at least one frequency-domain resource allocated for a downlink reception,

wherein the reference cell is identified as a cell with a smallest cell identifier (ID) among the at least one cell, and

wherein the reference cell is associated with a directional collision within each cell.

10 . The UE of claim 9 , in case that the first symbol is configured for the downlink reception in the at least one cell, the at least one cell includes at least one frequency-domain resource allocated for the uplink transmission.

11 . The UE of claim 9 , wherein the reference cell for the first symbol is determined based on another cell different from the at least one cell among the multiple cells.

12 . The UE of claim 9 , wherein a time-domain resource corresponding to the at least one frequency-domain resource includes the first symbol.

13 . A base station in a wireless communication system, the base station comprising:

a transceiver; and

a controller coupled with the transceiver, and configured to:

transmit, to a user equipment (UE), configuration information configuring multiple cells in a band for the UE,

wherein at least one cell from the multiple cells is used to determine a reference cell for a first symbol,

wherein, in case that the first symbol is configured for an uplink reception in the at least one cell, the at least one cell includes at least one frequency-domain resource allocated for a downlink transmission,

wherein the reference cell is identified as a cell with a smallest cell identifier (ID) among the at least one cell, and

wherein the reference cell is associated with a directional collision within each cell.

14 . The base station of claim 13 , in case that the first symbol is configured for the downlink transmission in the at least one cell, the at least one cell includes at least one frequency-domain resource allocated for the uplink reception.

15 . The base station of claim 13 , wherein the reference cell for the first symbol is determined based on another cell different from the at least one cell among the multiple cells.

16 . The base station of claim 13 , wherein a time-domain resource corresponding to the at least one frequency-domain resource includes the first symbol.
