    摘要: The present invention provides a method and an apparatus for controlling a radio frequency transmission, over a downlink to at least one mobile station user among a plurality of mobile station users, from a plurality of antennas associated with a base station in a wireless communication system. The method includes tracking a channel corresponding to the mobile station user of the plurality of mobile station users based on feedback information indicative of a state of the channel therefrom. The method further includes scheduling, for the at least one mobile station user, a directional transmission based on the tracked channels of the plurality of mobile station users.

    摘要: Techniques are provided for a radio link quality monitoring method and apparatus wherein a given user equipment device receives a plurality of Orthogonal Frequency Division Multiplex symbols that comprise a plurality of resource elements distributed in time and frequency, and which include reference symbols. The objective of the radio link quality monitoring is to predict the user equipment detection probability of control messages transmitted by the base station. The radio link quality estimation process calculates two average signal to noise ratio values over the complete frequency bandwidth for two assumed control channel formats corresponding to in-sync and out-of-sync conditions. The results of the calculations are then used to deduce the average error probabilities that are compared with predefined thresholds to provide the in-sync/out-of-sync indications.

    摘要: Method and receiver for processing a signal in a wireless communication system in which the signal comprises a sequence of chips. The signal is receive data at least one rake finger and sampled. There is a time spacing t1 between successive samples less than the time spacing tc between successive chips in the signal. Channel conditions on the channel are estimated and based on estimated channel conditions by the following steps: monitoring timing of the signal on one of the at least one rake finger to determine a time difference between the timing of the signal on the one of the at least one rake finger and the timing of the generation of the samples, the determined time difference being a multiple of t2, where t2
