  • Publication number: 20150201407
    Abstract: Methods and apparatuses are provided for wireless communication. Control symbols are mapped to a plurality of resource element groups (REGs), which are not assigned to a physical channel format indication channel (PCFICH) or a Physical hybrid automatic repeat request indicator channel (PHICH). The REGs are allocated in a time first manner. The mapped control symbols are transmitted on a packet dedicated control channel (PDCCH).

  • Patent number: 9083412
    Abstract: A Channel Quality Indicator (CQI) expression and feedback method prevents an excessive increase in the CQI feedback overhead while supporting both Single-User MIMO and Multi-User MIMO operations. When a default MIMO operation is set to Single-User MIMO or Multi-User MIMO, an access network can receive MIMO CQI feedback optimized for the corresponding MIMO operation. However, when a scheduler has selected an alternative MIMO operation other than the default MIMO operation, the access network calculates a CQI necessary for the alternative MIMO operation based on the default MIMO CQI feedback for the default MIMO operation and the DELTA CQI feedback for the alternative MIMO operation. In this manner, the invention enables the best operation in the default MIMO operation by providing a correct CQI, and enables the second best operation in the alternative MIMO operation.

  • Publication number: 20150188688
    Abstract: An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.

  • Publication number: 20150146763
    Abstract: Disclosed is a sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. The sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. In this environment, the sounding reference signal is transmitted through an antenna pattern through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead.
