摘要： Methods and apparatus for determining an impairment covariance matrix for use in an interference-suppressing CDMA receiver are disclosed. In several of the disclosed embodiments, precise information regarding signal propagation delays is not needed. An exemplary method includes the selection of a plurality of processing delays for processing a received CDMA signal. Net channel coefficients for the processing delays are estimated and used to calculate an impairment covariance matrix. The impairment covariance matrix is calculated as a function of the estimated net channel coefficients and the processing delays, without estimating a propagation medium channel response for the received signal.

摘要： Embodiments include methods for user equipment (UE) random access to a cell in a wireless network. Such methods include selecting one of a plurality of available random-access preambles and mapping the selected random-access preamble to one of a plurality of available physical uplink shared channel (PUSCH) resource units (PRUs) based on a mapping constraint. In the mapping constraint, one or more of the available PRUs are not used for the mapping and an integer number of the available random-access preambles are mapped to each of the available PRUs that are used for the mapping. Such methods also include transmitting the selected random-access preamble on a random access channel (RACH) and transmitting a data message on the PRU mapped to the selected random-access preamble. Other embodiments include complementary methods for a network node, as well as UEs and network nodes configured to perform such methods.

摘要： Coded digital data symbols sent through a transmission channel of a communications network are received in a receiver. Estimates (y) represented by a first number (a+b) of bits are calculated, and modified estimates (y') represented by a second number (c) of bits provided therefrom, the second number being lower than the first number. An amplitude value is calculated for each estimate (y), and an averaged amplitude value calculated for a number of amplitude values. A scaling factor (s) is calculated from the averaged amplitude value, and scaled estimates generated in dependence of the scaling factor. The scaling factor is used for a number of scaled estimates corresponding to the number of amplitude values for which the averaged amplitude value was calculated. Thus a better scaling factor is provided for most channel cases, which can still be calculated with the limited computational resources of a terminal for such networks.
