A base station transmits reverse scheduling information to a terminal, the reverse scheduling information being associated with one or more subframes of a radio data transmission between the terminal and the base station and comprising information indicating that at least part of the subframe(s) is not utilized for the radio data transmission. The reverse scheduling may be applied to semi-persistent scheduling (SPS) received at the terminal, resulting in reversed semi-persistent scheduling. The reverse scheduling (or de-allocation of resources) may be in response to the detection of excessive noise and/or interference, e.g. between a femto cell and a macro cell. With this mechanism, a network can mute selected terminals and/or signals to the terminals in a certain sub-frame or patterns of subframes, and previously allocated semi-persistent allocations may be temporarily cancelled. The invention has particular application to 3GPP Long Term Evolution (LTE) systems. |
