DETERMINING CHANNEL STATE INFORMATION AND REPORTING SAID INFORMATION Russian patent published in 2015 - IPC H04W72/08 

FIELD: radio engineering, communication.

SUBSTANCE: group of inventions relates to wireless communication. A rule stored in memory sets time correspondence between measurement configuration, indicating at least one subframe for taking measurements, and reporting configuration, indicating at least one subframe in which a report is to be transmitted. Said rule is used by both user equipment (UE) and a network to establish correspondence between a downlink subframe in which channel state information measurements are taken and an uplink subframe in which a report with channel state information is transmitted. The network may configure the UE by configuring measurements and configuring transmission of reports through allocated signalling and broadcasting. If measurement configuration is periodic and indicates, to take measurements, a plurality of downlink subframes, the rule leads to the establishment of one-to-one correspondence between the downlink subframe and the uplink subframe, wherein not all downlink subframes have correspondence with the uplink subframe; in case of aperiodic configuration, the rule indicates, to take measurements, a single downlink subframe.

EFFECT: reduced battery power consumption and easy memory operation.
