Abstract
Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. According to an embodiment of the present invention, a method for a terminal in a wireless communication system comprises: receiving system information and radio resource control (RRC) configuration information; identifying decoding-related information including an aggregation level by based on the system information and/or the RRC configuration information; and decoding control information on the basis of the aggregation level.
Claims15
A method of a terminal in a wireless communication system, the method comprising:
- receiving system information and radio resource control (RRC) configuration information;
- identifying decoding-related information including aggregation levels based on at least one of the system information or the RRC configuration information;
- and
- decoding control information based on the aggregation levels.
A method of a base station in a wireless communication system, the method comprising:
- transmitting decoding-related information including aggregation levels based on at least one of system information or radio resource control (RRC) configuration information;
- and
- transmitting control information, the control information being decoded based on the aggregation levels.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a controller configured to:
- receive system information and radio resource control (RRC) configuration information,
- identify decoding-related information including aggregation levels based on at least one of the system information or the RRC configuration information, and decode control information based on the aggregation levels.
The terminal of claim 11, wherein the aggregation levels are determined for each cell, the aggregation levels being not overlapped aggregation level determined for a first control resource set included in the same cell as a second control resource set to which the control information is transmitted, and
- wherein the first control resource set is used to transmit common control information.
The terminal of claim 12, wherein the aggregation levels are determined based on a type of a service being provided by the cell or coverage of the cell.
The terminal of claim 12, wherein the decoding-related information includes configuration information for the second control resource set, and
- wherein the controller is configured to control to decode the control information in the second control resource set based on the aggregation levels,
- wherein the configuration information for the second control resource set includes at least one of location information or periodicity information of the second control resource set,
- wherein the configuration information for the second control resource set is received via the RRC configuration information, and
- wherein the aggregation levels are received via the RRC configuration information or the system information.
A base station in a wireless communication system, the base station comprising:
- a transceiver;
- and
- a controller configured to:
- transmit decoding-related information including aggregation levels based on at least one of system information or radio resource control (RRC) configuration information, and
- transmit control information, the control information being decoded based on the aggregation levels.
The base station of claim 16, wherein the aggregation levels are determined for each cell, the aggregation levels being not overlapped aggregation levels for a first control resource set included in the same cell as a second control resource set to which the control information is transmitted, and
- wherein the first control resource set is used to transmit common control information.
The base station of claim 17, wherein the aggregation levels are determined based on a type of a service being provided by the cell or coverage of the cell, the decoding-related information includes configuration information for the second control resource set,
- wherein the control information is decoded in the second control resource set based on the aggregation levels,
- wherein the configuration information for the second control resource set includes at least one of location information or periodicity information of the second control resource set, and
- wherein the controller is configured to:
- transmit the configuration information for the second control resource set via the RRC configuration information, and
- transmit the aggregation levels via at least one of the RRC configuration information or the system information.
