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: 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: A method may include, by an apparatus, sensing at least one beam; initiating a channel occupancy time based on the sensing; transmitting at least one first downlink transmission on the at least one beam during the channel occupancy time, wherein the at least one first downlink transmission on the at least one beam triggers at least one first uplink transmission on the at least one beam during the channel occupancy time; receiving the at least one first uplink transmission on the at least one beam during the channel occupancy time; determining interference condition on the at least one beam based on the at least one first uplink transmission; and scheduling at least one second downlink transmission or at least one second uplink transmission on the at least one beam with restriction during a rest of the channel occupancy time when the interference condition meets at least one threshold requirement.

Abstract: Various communication systems may benefit from the appropriate communication of acknowledgements. For example, various communication systems, such as New Radio, may benefit from a scalable codebook size definition in a scenario with dynamically varying acknowledgement timing. A method can include receiving a timing offset value in a downlink grant (910). The method can also include determining a first downlink time slot within a feedback window based on the timing offset value (920).

Abstract: Various communication systems may benefit from efficient communications. For example, low latency long term evolution (LTE) systems may benefit from a short physical uplink shared channel (PUSCH) arrangement. A method may include operating a user equipment to follow a shortened transmission time interval. The shortened transmission time interval can be an integer number, L, of symbols in length. The method can also include sending a demodulation reference signal in at least a first symbol of the L symbols of the shortened transmission time interval.
