Listen-before-talk period for slotted access with scheduled traffic

A wireless device, comprising:

• transceiver circuitry configured to send and receive transmissions;
• and
• processing circuitry configured to control the transceiver circuitry and configured with a plurality of channel-sensing resources, each channel-sensing resource being associated with one or more corresponding transmission resources, wherein the processing circuitry is configured to:
• evaluate, in response to a determination that first data is ready to be transmitted by the wireless device, whether one or more of the plurality of channel-sensing resources are occupied by correlating a signal received during a channel-sensing period with a reference signal, wherein energy corresponding to the reference signal is removed and residual energy is compared to a predetermined threshold;
• determine a duration of the channel-sensing resources based at least in part on a result from a previous attempt to determine whether one or more other wireless devices were transmitting during an earlier transmission-time interval;
• detect that at least one of the plurality of channel-sensing resources is not occupied based on the comparison;
• transmit at least a part of the first data on at least one transmission resource associated with the at least one channel-sensing resource, in response to said detecting, wherein radio-frequency energy received during an interruption interval that begins after the transmission of at least the part of the first data, is analyzed and transmission of a second part of the first data is resumed or deferred, based on the analyzed radio-frequency energy received during the interruption interval;
• receive a grant for a scheduled transmission at least partly overlapping with at least one of the plurality of channel-sensing resources, subsequently to said evaluating, detecting, and transmitting;
• and
• transmit second data in accordance with the received grant, wherein the processing circuitry is configured to perform said evaluating by analyzing radio-frequency energy received in the first one of the one or more channel-sensing resources during a first analysis period, having a first duration, and wherein the processing circuitry is further configured to:
• analyze, in a pre-scheduled transmission time interval, radio-frequency energy received in a second one of the one or more channel-sensing resources during a second analysis period overlapping the first analysis period and having a second duration;
• and
• transmit at least the part of the first data on a second transmission resource, corresponding to the second one of the one or more channel-sensing resources, in response to determining, based on the analyzing of the radio-frequency energy received in the second one of the one or more channel-sensing resources, that the second one of the one or more channel-sensing resources is not occupied.
