METHOD AND DEVICE FOR REALIZING SEMI-PERSISTENT SCHEDULING SERVICE OR SIMILAR SEMI-PERSISTENT SCHEDULING SERVICE

摘要

The present invention discloses a method and device for realizing semi-persistent scheduling (SPS) service or similar SPS service. The method includes that: the period of the SPS or similar SPS is notified to a terminal, so that the terminal, according to the period, transmits the data of the SPS service or similar SPS service by using a transmission mode in which close-loop rank is 1; the precoding matrix indicator (PMI) desired when the SPS service or similar SPS service supports the transmission mode in which close-loop rank is 1 is dynamically notified to the terminal, so that the terminal uses a recently received PMI when transmitting the data of the SPS service or similar SPS service; a base station receives the data of the SPS service or similar SPS service transmitted by the terminal based on the transmission mode in which close-loop rank is 1. With the present invention, the multi-input multi-output (MIMO) transmission mode in which close-loop rank is 1 can be supported by the SPS service or similar SPS service.
