  • Patent number: 10909158
    Abstract: A method and apparatus for generating information are provided. An embodiment of the method includes: collecting characteristic information of a target user, and dividing the collected characteristic information into at least two dimensions, the characteristic information including user information and user behavior information; selecting the dimension associated with a target service type from the plurality of dimensions; and generating a target number of characteristic information sets based on cluster analysis on the characteristic information in the selected dimension. The embodiment can generate a characteristic information set corresponding to a user of any service type using the characteristic information of the target user, thereby improving the universality of the method for generating information.

  • Patent number: 9401787
    Abstract: An approach is provided for generating a pilot pattern. A sequence of tiles is generated, wherein the tiles are arranged to avoid redundant pilot sub-carriers by utilizing different pilot patterns. A transmission signal is generated according to the generated sequence for transmission over a network.

  • Patent number: 9294180
    Abstract: A pilot transmission in a multiple antenna closed loop transmission time multiplexes a beam-specific pilot and an antenna-specific pilot in two short blocks of one uplink sub-frame. The beam-specific pilot is transmitted as an in-band pilot with the same beam as data to provide optimal data demodulation/estimation. The antenna-specific pilot is transmitted as an out-band pilot to provide optimal beam selection.

  • Patent number: 8520640
    Abstract: A method for determining whether to perform handover of a UE apparatus to a candidate cell and carrier frequency of a TD-CDMA telecommunications network (such as a TD-SCDMA network) based separately on coverage and capacity, using one decision metric for coverage (e.g. based on received signal code power for the candidate cell and carrier frequency) and a different decision metric for capacity (e.g. based on a quantity proportional to the received signal code power for the candidate cell and carrier frequency and inversely proportional to a measure of total interference in the candidate cell on the carrier frequency. Corresponding equipment and a computer program product are also provided. In deciding whether handover is needed based on capacity, a threshold for received signal code power may be used in addition to the metric for capacity.

  • Publication number: 20080012764
    Abstract: A device configured to perform communication operations, the device having a transceiver and a control unit. The transceiver is configured to receive a signal incorporating scheduling grant and antenna weight feedback information from a remote receiver in a wireless communications system. The control unit is configured to verify correct receipt of the signal incorporating the scheduling grant and antenna weight feedback information and to use the antenna weight feedback information to control beamforming operations performed by the device when performing signal transmission operations. A computer program product composed of a computer readable memory medium storing a computer program.
