摘要： A flexible and resource-efficient despreading-on-demand (DoD) technique is described where only channels that actually contain data to be despread are despread, and only a single despreading operation need be performed using the actual spreading factor associated with that data. In one example, the data portion of the received signal is buffered for a frame so that an associated transport format, including the actual spreading factor, can be determined before the data is despread. The data is buffered in a memory at a first rate and then subsequently read out at a second rate that is considerably faster than the first rate. The fast data read-out allows despreading at a high rate so that the despread data symbols from the buffered frame are available for further processing shortly after the last sample belonging to the frame has been received.

A signal is received comprising symbols of the serving cell transmitted in a downlink channel and symbols of the one or more interfering cells and a first function of a signal-to-interference ratio of the received signal is calculated. One or more of the interfering cells are selected as dominant interfering cells based on a respective average power of reference symbols of the one or more interfering cells in the received signal, an average power of demodulated symbols of the serving cell in the received signal and a respective average power of demodulated symbols of each of the dominant interfering cells in the received signal are determined. A metric value is calculated based on the average power of demodulated symbols of the serving cell and on the respective average power of demodulated symbols of each of the dominant interfering cells, a channel condition indication is determined based on the metric value and the first function of the signal-to-interference ratio of the received signal, and the channel condition indication is transmitted to the cellular communication system, thereby providing downlink channel condition information to a network node. A method of creating a look-up table for mapping the first function and the metric value to the channel condition indication is also disclosed along with computer program products, arrangements and wireless communication devices corresponding to the methods.

摘要： Downlink diversity in a COMA system is provided by employing Walsh codes in conjunction with M transmit antennas at a common base station serving K mobiles, where M may or may not be to equal to K . The present invention provides methods and apparatus for improving downlink diversity in a CDMA system. Each transmit antenna transmits a signal representing the result of the modulation of Walsh codes by data signals for each of the K mobiles, assuming there is data pertaining to a particular mobile. The assignment of Walsh codes is accomplished in accordance with a transmission matrix T . The transmission matrix maps the user data symbols onto the Walsh codes for each antenna and is preferably designed such that its columns are representative of the transmit antennas and orthogonal. Thus, at a given mobile, the mobile need only correlate with M different Walsh codes since each transmit signal received contains a component that is the result of M different Walsh codes having been modulated by a data signal associated with that particular mobile. The set of Walsh codes to select from includes 2 ┌log 2 ( K )┐ Walsh codes. However, with respect to any given mobile, there is needed only as many different Walsh codes as there are transmit antennas serving the particular mobile. The results of the respective M correlations are combined and, with obtained channel estimates, the receiver estimates the particular data pertaining to that particular mobile so that it can be provided to the user. Also, the present invention provides for various ways to estimate the respective channels between the M transmit antennas and a mobile. It is to be appreciated that the downlink diversity techniques of the invention may be applied to the physical layer proposed in the IS95-C physical layer draft proposal.

摘要： An apparatus, system, method and program detect and reduce interference in cell sites of a wireless communications network. A cell site from the cell sites of the wireless communications network is selected and signal code power measurements from mobile devices in the cell site are received so that the sources of signals being transmitted to the mobile devices can be determined. Interfering sources are determined based on the signal code power measurements and the active set of sources for the mobile devices. The signal code power measurements are summed and ranked, and interfering transmitters associated with the ranked signal code power measurements for the interfering sources are determined. The same procedure is repeated for all cell sites of the wireless communications network, and the transmitter that is an interfering source for the highest number of cell sites is selected as a problem (interfering) transmitter. The parameters of the problem transmitter and the corresponding antenna are altered and performance of the wireless network in a critical zone around the problem transmitter and interference in the cell sites interfered by the problem transmitter are monitored. Altering of the parameters of the problem transmitter and the corresponding antenna is performed continuously until a desired interference reduction is achieved in the cell sites interfered by the problem transmitter.
