Abstract: Various communication systems may benefit from appropriate handling of uplink communications. For example, certain wireless communication systems may benefit from an uplink coverage extension for unlicensed band operation. A method can include configuring a first interlace having a first starting physical resource block. The method can also include configuring a second interlace having a second starting physical resource block offset from the first physical resource block. The method can further include transmitting or receiving a signal based on a combination of the first interlace and the second interlace. The combination can include at least one cluster but less than two clusters in each measurement interval.

Abstract: There is provided a frame structure for a cellular communication system. According to an embodiment, there is provided a first radio frame configuration defining a frame structure of a radio frame comprising at least one sub-frame dedicated only for downlink transmission. There is also provided a second radio frame configuration defining a frame structure of a radio frame comprising at least one flexible special sub-frame configurable as either a flexible downlink sub-frame or as a flexible uplink sub-frame, wherein the flexible downlink sub-frame and the flexible uplink sub-frame both comprise an uplink part and a downlink part, and wherein both the uplink part and the downlink part carry at least one of control information and a reference signal. Amongst a set of radio frame configurations comprising at least the first and second radio frame configuration, a radio frame configuration is selected and a radio signal carrying an information element indicating the selected radio frame configuration is exchanged in order to configure the selected radio frame configuration for use in the cellular communication system.

Abstract: The disclosure relates operation where information of at least one selected resource from a pool of resources for control signals in uplink is signalled in downlink. At least one resource is selected from a pool of resources for control signals in the uplink, where after information of the selected at least one resource is signalled in the downlink. Communication of control signals in the uplink by at least one device is facilitated such that at least one non-selected resource from the pool of resources is used in sending of control signals in the uplink. The at least one resource is implicitly derived in accordance with a predefined rule.
