A method may include receiving, by a user equipment incapable of transmitting and receiving simultaneously, a schedule to transmit data on an uplink, detecting, by the user equipment, whether there is data to be transmitted on the uplink, and receiving, by the user equipment, during a time corresponding to the schedule, data associated with a downlink, when it is determined that there is no data to be transmitted.

UL/DL scheduling for full bandwidth utilization

A method, node, and system are provided that overcome problems with using inaccurate estimates of a current round trip time RTT for verifying the ACK/NACK information received in an ACK/NACK report, e.g., a piggy-backed ACK/NACK (PAN). This is accomplished by de-coupling the RTT from the ACK/NACK analysis performed in the sending node that receives the ACK/NACK report. As a result, unnecessary re-transmissions are avoided, communication delays are decreased, and spectrum and other system resources are used more efficiently.

Method and apparatus for ACK/NACK reporting

A method and a system is disclosed for improving transmission of timing advance messages to a mobile station, in a network employing adaptive antenna systems. In a typical embodiment each TA-message is dedicated to one mobile and sent in the adaptive antenna beam that covers the area where the desired mobile is located.
