摘要： There is provided a method, performed by a communication station, for Listen-Before-Talk, LBT, based medium access. The method comprises the step (S1) of performing an LBT-based medium access procedure including sensing a radio-based medium on a shared radio spectrum during a sensing duration, deferring transmission if an on-going transmission is detected during the sensing, and transmitting on the radio-based medium if no on-going transmission is detected during the sensing. The method further comprises the step (S2) of waiting, when the communication station has transmitted, for a waiting duration that is based on a time duration between consecutive sensing occasions for at least one other communication station, also operating according to an LBT-based medium access procedure on the shared radio spectrum, before performing the LBT-based medium access procedure again.

摘要： Embodiments herein relate to a first communication device (110; 121; 122; 123) and method therein for transmitting data information at fixed time instants on a radio channel to a second communication device (121; 122; 123; 110) in a radio communications network (100). First, the first communication device (110; 121; 122; 123) determines that the radio channel is available for transmitting data information to the second communication device (121; 122; 123; 110) during a time period determined by the first communication device (110; 121; 122; 123). Then, the first communication device (110; 121; 122; 123) transmits a preamble on the available radio channel after the time period. The first communication device (110; 121; 122; 123) thereafter transmits the data information on the available radio channel to the second communication device (121; 122; 23; 110) at a next fixed time instant following the transmission of the preamble.

摘要： A communication device (10, 100-1, 100-2, 100-3, 100-4) detects potentially colliding usage of transmission resources. Further, the communication device (10, 100-1, 100-2, 100-3, 100-4) detects cease of the potentially colliding usage of the transmission resources. After expiry of a backoff time period starting when detecting the cease of the usage of the transmission resources, the communication device (10, 100-1, 100-2, 100-3, 100-4) performs a transmission on the transmission resources. This transmission is performed synchronously with a further transmission on the transmission resources by at least one other communication device (10, 100-1, 100-2, 100-3, 100-4).
