## Abstract

The present disclosure provides a method used in a base station, comprising: sending indication information to user equipment (UE), the indication information indicating a correspondence between multiple logical channels or bearers and multiple scheduling request (SR) configurations, wherein each logical channel or bearer is associated with a subcarrier spacing (SCS) and/or transmission time interval (TTI).

## Claims

### Claim 1

A method performed by a user equipment (UE), the method comprising:
receiving a Radio Resource Control (RRC) message which contains
a first parameter for each of one or more scheduling request (SR) configurations, wherein the first parameter is included in a first information element (IE) for each of the SR configurations, and
a second parameter for each of one or more logical channel configurations, wherein the second parameter is included in a second IE for each of the logical channel configurations,
wherein the first parameter is an integer, and each of the SR configurations is used to configure parameters for dedicated SR resources,
each of the logical channel configurations is used to configure logical channel parameters, and
the second parameter for each of the logical channel configurations has a value that is same as a value of the first parameter for the SR configuration to which a logical channel configured by each of the logical channel configurations is mapped.

### Claim 2

A method performed by a base station, the method comprising:
sending a Radio Resource Control (RRC) message which contains
a first parameter for each of one or more scheduling request (SR) configurations, wherein the first parameter is included in a first information element (IE) for each of the SR configurations, and
a second parameter for each of one or more logical channel configurations, wherein the second parameter is included in a second IE for each of the logical channel configurations,
wherein the first parameter is an integer, and each of the SR configurations is used to configure parameters for dedicated SR resources,
each of the logical channel configurations is used to configure logical channel parameters, and
the second parameter for each of the logical channel configurations has a value that is same as a value of the first parameter for the SR configuration to which a logical channel configured by each of the logical channel configurations is mapped.

### Claim 3

A user equipment (UE), comprising:
a receiving unit configured to receive a Radio Resource Control (RRC) message which contains
a first parameter for each of one or more scheduling request (SR) configurations, wherein the first parameter is included in a first information element (IE) for each of the SR configurations, and
a second parameter for each of one or more logical channel configurations, wherein the second parameter is included in a second IE for each of the logical channel configurations,
wherein the first parameter is an integer, and each of the SR configurations is used to configure parameters for dedicated SR resources,
each of the logical channel configurations is used to configure logical channel parameters, and
the second parameter for each of the logical channel configurations has a value that is same as a value of the first parameter for the SR configuration to which a logical channel configured by each of the logical channel configurations is mapped.

### Claim 4

A base station, comprising:
a sending unit configured to send a Radio Resource Control (RRC) message which contains
a first parameter for each of one or more scheduling request (SR) configurations, wherein the first parameter is included in a first information element (IE) for each of the SR configurations, and
a second parameter for each of one or more logical channel configurations, wherein the second parameter is included in a second IE for each of the logical channel configurations,
wherein the first parameter is an integer, and each of the SR configurations is used to configure parameters for dedicated SR resources,
each of the logical channel configurations is used to configure logical channel parameters, and
the second parameter in for each of the logical channel configurations has a value that is same as a value of the first parameter for the SR configuration to which a logical channel configured by each of the logical channel configurations is mapped.
