摘要： In a telecommunication network, pilot signals are provided in orthogonal frequency division multiplexing frames to enable a single-carrier frequency division multiple access method to work substantially harmoniously with an orthogonal frequency division multiplexing access method in uplink. Each orthogonal frequency division multiplexing frame comprises a plurality of orthogonal frequency division multiplexing symbols. At least one pilot signal is placed within at least one existing orthogonal frequency division multiplexing symbol.

摘要： According to an example embodiment, a method may include allocating, within a single physical resource unit (PRU), a plurality of channel sounding groups. Wherein each channel sounding group includes a frequency-time domain code division multiplexing (CDM) allocation. The method may also include broadcasting, in a downlink direction to one or more mobile stations in a wireless network, a signal that causes the receiving mobile stations to transmit a channel sounding signal. The method may further include receiving at least one channel sounding signal from at least one of the one or more mobile stations, the channel sounding signal being received in an uplink direction via one or more channel sounding groups. And, the method may include estimating the channel quality, of the channel used by the physical resource unit, based upon the received at least one channel sounding signal.

摘要： The present invention relates to methods and apparatuses for providing selective network access, wherein a cell type indication is provided based on at least one of a preamble and a header portion of a broadcast signal. At the receiving end, it is checked based on at least one of the preamble and the header portion, whether broadcast signals are received from different first and second cell types. The first cell type is selected for network access, if both broadcast signals from the first and second cell types are received with sufficient strength.
