This disclosure describes methods, systems, and devices for wireless communications in which a transmitting device using a shared radio frequency spectrum can perform a listen-before-talk (LBT) procedure for at least a minimum defer time and, after successfully completing the LBT procedure, can occupy the spectrum for a duration of a channel occupancy time (COT). The transmitting device can interrupt transmission for a gap period during the COT and resume transmission after the gap period without performing another LBT procedure. The minimum defer time can be based on a periodicity of channel reservation signals transmitted by one or more other devices using the shared radio frequency spectrum. In some cases, the transmitting device can schedule one or more receiving devices with resources for transmission during the COT, and the receiving devices can perform LBT that is not adjacent to associated transmissions.

The present document relates to a communication method considering a time domain overlapping situation between signals transmitted through a direct communication link, and a user device therefor. To this end, the communication method comprises: receiving, by a second user equipment (UE), a physical control channel through a direct communication link and a physical shared channel corresponding to the physical control channel in a first time resource from a first UE performing communication through the direct communication link; and receiving a reference signal (RS) for beam management of the direct communication link. In this case, for the physical control channel / physical shared channel, a second time resource for retransmission is reserved on the basis of control information transmitted by the physical control channel, and the receiving of the RS includes receiving a standalone RS without data transmission through a third time resource. In the present invention, when the third time resource overlaps with the first time resource / the second time resource, a reception beam is determined on the basis of the priority between the standalone RS and the physical control channel / physical shared channel.

The implementation scheme is as follows: in the face of the staring coverage mode, the global ground surface area is divided into several position areas according to the longitude and latitude; the number of new call users in each position area in a future period of time is predicted according to the user behavior data of each position area at historical time and the user behavior data at the current time; the user access success rate, the user switching success rate and the user average weighted satisfaction are set as the utility function, and the optimal channel resource threshold of all low-orbit satellites and the optimal switching channel of the switching user are periodically calculated. The present application improves the user access success rate and the user switching success rate, reduces the calculation amount of user access and switching, improves the user service satisfaction and the channel resource utilization rate, and can be used in the satellite communication network.

This invention claims protection for a high-efficiency, high-bandwidth-utilization directional access control method for terahertz wireless networks, comprising: designing a memory-assisted control interaction mechanism; designing a priority-based channel reservation mechanism; each node in the network maintains a location information storage table to store location information that the node has broadcast in the network, and the node's location information can be quickly obtained by looking up the table. During the control interaction process, whether or not the location information field in the control frame is omitted is determined by whether the location information has changed, thereby reducing the control interaction time and increasing the time for data transmission on the THz channel. By setting priorities for nodes, the success rate of nodes that can transmit data in parallel to compete for the channel is increased, the channel is reserved in advance, and the utilization rate of the THz channel is improved.

And carrying out relay forwarding on the received to-be-sent data until a destination node, and if no busy cluster head node exists, carrying out full-duplex handshake with the destination node and sending the to-be-sent data to the destination node. According to the invention, the transmission time delay of long-distance super multi-hop and the blocking probability during sudden large flow can be greatly reduced.
