Methods and devices to perform satellite communication

Abstract

An apparatus of a network access node, the apparatus may include a memory and a processor configured to: determine a time-division duplex communication pattern including a plurality of time slots for communication between the network access node and a terminal device; allocate first time slots of the plurality of time slots for the network access node to perform uplink and/or downlink communication; allocate a number of second time slots of the plurality of time slots during which the network access node is scheduled to perform neither uplink communication nor downlink communication with the terminal device, wherein the number of the second time slots is based on a round trip time delay of the network access node; and schedule the terminal device to transmit uplink communication signals or receive downlink communication signals during at least one second time slot of the second time slots.
