METHOD AND DEVICE FOR REALISING SEMI-PERSISTENT SCHEDULING SERVICE OR SEMI-PERSISTENT SCHEDULING-LIKE SERVICE

摘要

FIELD: physics, computer engineering.;SUBSTANCE: invention describes realisation of a semi-persistent scheduling or semi-persistent scheduling-like service. Provided are steps of: notifying a terminal of its SPS or SPS-like period, so that the terminal sends SPS service or SPS-like service data according to the period and by selecting a transmission mode with a closed loop rank 1; dynamically notifying the terminal of a precoding matrix indicator PMI required for its SPS or SPS-like service to support the transmission mode with the closed loop rank 1, so that the terminal uses the last received PMI when sending the SPS service or SPS-like service data; and receiving, by a base station and based on the transmission mode with the closed loop rank 1, the SPS service or SPS-like service data sent by the terminal.;EFFECT: supporting a MIMO transmission mode with a closed loop rank 1.;7 cl, 12 dwg
