  • Publication number: 20150341942
    Abstract: Methods, systems, apparatuses, evolved NodeB (EnBs), User Equipment (UE), and chip sets for all of the same, in cellular communication systems are described. One method for a UE includes receiving a Channel State Information Reference Signal (CSI-RS) transmitted by an eNB according to a pattern in a time-frequency resource grid determined based on the transmission scheme of the eNB, measuring the state of the transmission channel using the CSI-RS, generating channel state information based on the measuring, and transmitting the channel state information as feedback. The UE receives a downlink signal including data and a Cell-specific Reference Signal (CRS) from the eNB and estimates the transmission channel using the CRS and then acquires the data using the estimated channel.

  • Patent number: 9143717
    Abstract: A broadcast receiver and method of providing a preferred channel thereof are disclosed. The present invention includes receiving a program of the preferred channel (52) set by a user among a plurality of broadcast channels, transforming an image of the received program of the preferred channel into a reduced image (54) and storing the reduced image per the preferred channel. Accordingly, when a turn-on mode of the broadcast receiver is switched to a turn-off mode (56) of the broadcast receiver, when a turn-off mode (56) of the broadcast receiver is switched to a turn-on mode of the broadcast receiver, or when a display of a preferred channel is requested in a turned-on mode, a per preferred channel reduced image is displayed as OSD (60) on a currently viewed image. So, a user is facilitated to recognize and select a program received on the preferred channel without blocking the currently viewed image.
