Abstract: There is provided a method for defining at least one channel reservation window the method comprising: setting length for each of the at least one channel reservation window such that each channel reservation window comprises a plurality of sub-frames; dividing the length of each channel reservation window into a transmission part and an idle part, wherein the idle part consists of one or more symbols in one sub-frame; maximizing, at a symbol level accuracy, the length of the transmission part such that a ratio between the length of the idle part and the length of the transmission part fulfils a predetermined criterion; and concatenating the transmission part and the idle part so as to form the channel reservation window.

Abstract: Channel state information is generated by a communication device. The device can determine that at least one uplink resource element of a radio frame is to be left unoccupied and perform at least one interference measurement on at least one downlink resource element coinciding with the at least one unoccupied uplink resource element, A channel state information report can then be generated based on the measurement, A network node may cause the communication device to leave at feast one uplink resource element of a radio frame unoccupied.

Abstract: A method includes receiving initial acknowledgement resource information at a user device from a base station. The initial acknowledgement resource information is associated with a subset of acknowledgement resources. The method includes determining in dependence on the initial acknowledgement resource information which of the subset of acknowledgement resources is to be used. The user device transmits an acknowledgement on the determined resource.

Abstract: Systems, methods, apparatuses, and computer program products for an enhanced random access channel (RACH) procedure are provided. One method may include receiving an access request comprising a signature from at least one user equipment. The method may then include providing, to the at least one user equipment, multiple at least partially overlapping resource opportunities for a first scheduled transmission, and performing blind decoding of the first scheduled transmission for the multiple at least partially overlapping resource opportunities

Abstract: Various communication systems may benefit from an appropriate usage of resources. For example, certain wireless communication systems may benefit from appropriate usage of periodic and aperiodic physical uplink control channel resources for hybrid automatic repeat request acknowledgment feedback. A method can include receiving, from an access node, an acknowledgment/negative acknowledgement resource indicator in a downlink assignment. The indicator can correspond to two or three resource sets. The method can also include determining, by a user equipment, a resource for hybrid automatic repeat request acknowledgment transmission based on the acknowledgment/negative acknowledgement resource indicator and based on an outcome of a listen before talk procedure.

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.
