Abstract: Various communication systems may benefit from signaling that instructs operation of devices. For example, certain wireless communication systems can benefit from signaling of listen-before-talk type for unlicensed spectrum operation. A method can include receiving a mapping between listen before talk type and a set of one or more of downlink ending partial subframe durations. The method can also include receiving indication of at least one downlink ending partial subframe duration of the plurality of downlink ending partial subframe durations. The method can further include determining a listen before talk type based on the received indication and the received mapping. The method can additionally include communicating with at least one access node based on the determined listen before talk type.

Abstract: Various communication systems may benefit from improved uplink data transmission. A method may include determining an assignment, at a user equipment, of a first set of physical resource blocks in an unlicensed spectrum to a physical random access channel. The physical random access channel occupies at least one of the physical resource blocks, and wherein the at least one of the physical resource blocks occupied by the physical random channel are distributed into clusters in a frequency domain. The method may also include determining an assignment, when the user equipment transmits data, of a second set of at least one remaining physical resource block of the physical resource blocks to at least one uplink channel. In addition, the method can include transmitting random access preambles through the physical radio access channel or data through of the at least one the uplink channel from the user equipment to a network entity.
