Abstract:
A chipset is provided. The chipset is configured to detect an interference characteristic of a neighbor cell corresponding to groups and perform an interference whitening operation based on the interference characteristic. The groups are generated by dividing a time interval occupied by a first reference signal region by dividing a frequency band occupied by the first reference signal region, or by dividing a time interval occupied by a second reference signal region. A frequency band occupied by the second reference signal region is wider than the frequency band occupied by the first reference signal region.
Abstract:
A method and an apparatus for measuring a link quality in a wireless communication are provided. The method of a receiver for measuring the link quality in the wireless communication system includes determining a modulation type for each of at least one reception stream received through at least one antenna based on a modulation order and channel information regarding each of signals transmitted from a plurality of transmission antennas, searching for a parameter corresponding to the determined modulation type from a pre-stored parameter table in which parameters for each modulation type are stored, and calculating a channel capacity for each of the at least one reception streams received through the at least one antenna by using the searched parameter.
Abstract:
A chipset including at least one processor is provided. The at least one processor of the chipset is configured to acquire an interference whitening (IW) and detection scheme and demodulate an interference signal based on the acquired IW and detection scheme, wherein the IW and detection scheme is determined based on an interference characteristic of the interference signal, and the interference characteristic is determined based on whether a region in which the interference signal is included collides with a reference signal region of a serving cell and whether the interference signal is a reference signal.
Abstract:
A method and an apparatus for measuring channel quality in a MIMO system is provided. The method includes measuring a first SINR based on an assumption that a first detector is used, using a channel estimation value of a reception signal with respect to each of a plurality of space layers, and a second SINR for each of the plurality of space layers corresponding to a case where the plurality of space layers exist independently using the channel estimation value of the reception signal; determining a Log Likelihood Ratio of reception data based on an assumption that a second detector is used, with respect to each of the plurality of space layers; and generating channel quality information based on an assumption that the second detector is used, based on the first SINR and the second SINR with respect to each of the plurality of space layers, and the LLR.
