1. A method, comprising:
- receiving a first configuration for grantless uplink subframes from a network node via radio resource control signaling as a bitmap indicating for one or more subframes whether or not grantless uplink transmissions is allowed;
receiving a second configuration for determining restrictions for grantless uplink subframes that are additional to those received in the first configuration; and
determining from the received second configuration when grantless uplink transmission is not allowed for at least one grantless uplink subframe,wherein the determining further comprisesdetermining that uplink signals are scheduled to be transmitted in a subframe; and
determining whether grantless uplink transmission is allowed in the subframe, or subframes before or after the subframe.

7. An apparatus, comprising:
-
at least one processor; and at least one memory including computer program instructions, wherein the at least one memory and computer program instructions are configured to, with the at least one processor, cause the apparatus at least to; receive a first configuration for grantless uplink subframes from a network node via radio resource control signaling as a bitmap indicating for one or more subframes whether or not grantless uplink transmissions is allowed; receive a second configuration for determining restrictions for grantless uplink subframes that are additional to those received in the first configuration; and determine from the received second configuration when grantless uplink transmission is not allowed for at least one grantless uplink subframe, wherein the at least one memory and computer program instructions are further configured, with the at least one processor, to cause the apparatus, when determining when grantless uplink transmission is not allowed, at least to; determine that uplink signals are scheduled to be transmitted in a subframe; and determine whether grantless uplink transmission is allowed in the subframe, or subframes before or after the subframe. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus, comprising:
-
at least one processor; and at least one memory including computer program instructions, wherein the at least one memory and computer program instructions are configured to, with the at least one processor, cause the apparatus at least to; signal a first configuration for grantless uplink subframes to at least one user equipment via radio resource control signaling as a bitmap indicating for one or more subframes whether or not grantless uplink transmissions is allowed; and signal a second configuration for the user equipment to determine restrictions regarding when grantless uplink transmission is not allowed that are additional to those signaled in the first configuration, wherein the grantless uplink transmission not allowed depends on at least one of the following;
whether the grantless uplink transmission occupies whole carrier or not, and whether the grantless uplink transmission coincides with uplink subframes in a transmission opportunity on an unlicensed carrier. - View Dependent Claims (14, 15, 16, 17)
