A method, system, apparatus, and computer program can provide scheduling of direct to direct communication by a high speed packet access base station. The method, for example, can include obtaining a direct user equipment communication toggling message. The method can also include interpreting physical layer signaling on a first frequency of a first radio system based on the toggling message. The method can further include scheduling a direct user equipment pair on a second frequency of a second system based on the interpreting. The toggling message can include a triggering message to initiate direct user equipment communication or an exit message to terminate direct user equipment communication.

Scheduling of device-to-device communication

Equipment for transmitting a signal, the equipment comprising an antenna array (-) for providing three or more radiation antenna patterns. The equipment is arranged to transmit a primary common pilot signal with at most two radiation patterns and a secondary common pilot signal with at least one radiation pattern. The equipment comprises controllers (-) for adjusting the power ratio between the primary and the secondary common pilot signal and the total power of the primary and the secondary common pilot signals, and controllers (-) for adjusting the transmit power of the dedicated pilot signal, such that the power levels of the dedicated pilot signals transmitted with the same radiation patterns as the secondary common pilot signal are relatively higher than the power levels of the dedicated pilot signals transmitted with the same radiation patterns as the primary common pilots.

Data transmission method and equipment

A method for transmitting from a multi-antenna station and a multi-antenna station is provided. The station is provided with a reference antenna and a diversity antenna. During the operation of the method, one of the antennae is selected to be stronger in the event of power unbalance between the diversity and reference antennae. Greater transmission power is assigned for the diversity antenna than the reference antenna when the diversity antenna is only phase adjusted. Greater transmission power is assigned for the reference antenna than the diversity antenna when the reference antenna is amplitude adjusted.
