摘要： For use in a heterogeneous network, a method for enabling interference coordination includes, upon occurrence of a trigger condition, determining, at a first low power node, that the first low power node is approaching a second low power node. The method also includes sending, at the first low power node, an entering message to an evolved Node-B (eNB) that serves the first low power node. The method further includes receiving, at the first low power node, configuration information from the eNB to perform at least one measurement of the second low power node.

摘要： In a communication system, a base station transmits power setting information in a downlink Physical Downlink Shared Channel (PDSCH). A mapping scheme between overhead signals and reference signal (RS) overhead ratios, and the traffic-to-pilot ratios (T2P) calculation methods are established. A user-specific T2P ratio for certain OFDM symbols, a RS overhead ratio and a calculation method selected from the plurality of T2P calculation methods are assigned to a wireless terminal. An overhead signal corresponding to the assigned RS overhead ratio and the assigned T2P calculation method is selected in accordance with the mapping scheme and transmitted to the wireless terminal. In addition, the user-specific traffic-to-pilot ratio is transmitted to the wireless terminal. The wireless terminal calculates the traffic-to-pilot ratios across different transmission antennas and different OFDM symbols based on the received traffic-to-pilot ratio, the RS overhead ratio and the T2P calculation method indicated by the RS overhead signal.

摘要： Methods and circuits for assigning pilot boosting factors and calculating traffic to pilot ratios in a wireless communication system. The data to be transmitted is first modulated to generate a plurality of data modulation symbols. The plurality of data modulation symbols and a plurality of reference signal symbols are mapped into transmission resources of each of a plurality of antennas in accordance with a transmit diversity scheme. The transmission resources of each of the antennas are divided into a plurality of subcarriers in a frequency domain and a plurality of time units in a time domain. Then, a power scaling factor are assigned for data modulation symbols on each of the antennas in dependence upon power levels of the reference signal symbols to maintain a fixed power level across the plurality of antennas in each time unit. Finally, the data modulation symbols and the reference signal symbols are transmitted via the plurality of antennas in accordance with the mapping scheme and the assigned scaling factors.
