Method and network node for handling signals transmitted from wireless devices

Abstract:

There is disclosed a method and a network node for handling signals transmitted from one or more wireless devices in a wireless network when Time Division Duplex (TDD) is employed such that two successive uplink subframes of a radio frame are separated by an intermediary time interval. The signals are received during a subframe reserved for uplink transmissions, and a sending time interval with a length of at least a subframe is selected. Then, the received signals are sent to a transport network such that the signals are distributed over the selected sending time interval instead of being sent virtually at the same time as in conventional procedures. Thereby, the signals will be distributed over a longer time when arriving at the transport network which will have time to handle the signals properly such that any loss of packets can be avoided or at least reduced.
