Abstract: A method including forming a reservation signal including a first part and a second part; and transmitting the reservation signal by a base station in a first cell on a channel during a portion of a first subframe until start of a next following subframe. The first part is configured to reserve the channel between the base station and a user equipment (UE). The second part includes downlink Orthogonal Frequency Division Multiplexing (OFDM) symbols carrying at least one of Physical Downlink Shared Channel (PDSCH), Demodulation Reference Signal (DMRS), Cell Specific Reference Signal (CRS), Physical Downlink Control Channel (PDCCH), or a same Transport Block (TB) as a PDSCH on the next following subframe, and the portion is less than the entire first subframe.

Abstract: According to an example aspect of the present invention, there is provided a method, comprising: receiving, by a first device from a second device, a message on a wireless medium indicating that the wireless medium has been reserved for at least one transmission from the first device to the second device by the second device detecting that the wireless medium is not occupied, based on a first beamwidth. The method further comprises determining, by the first device, a second beamwidth for performing the at least one transmission, selecting, by the first device on the basis of the received message, a method for the first device, from a set of at least two methods, to determine whether the wireless medium is occupied, determining, by the first device, based on the selected method for the first device whether the wireless medium is occupied, and in response to detecting that the wireless medium is not occupied, performing the at least one transmission by the first device.

Abstract: According to a first embodiment, a method may include initiating, by a user equipment, a first countdown timer associated with a first initial value and a first timer-interval, and a second countdown timer associated with a second initial value and a second timer-interval. The method may further include determining, by the user equipment, whether at least one first indication is detected during the first timer-interval. The method may further include adjusting, by the user equipment, at least one of the first countdown timer or the second countdown timer based on the determining.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for downlink control of unlicensed sub-bands. The method comprises determining a search space configuration associated with control resources on a plurality of sub-bands which are unlicensed, the search space configuration indicating candidates for detection of downlink control information for the plurality of sub-bands; determining, from the search space configuration, positions of the candidates on the control resources within each of the plurality of sub-bands; mapping an available number of candidates to the determined positions based on a transmission bandwidth assumed by a terminal device; and transmitting downlink control information to the terminal device on the mapped candidates.
