Abstract

The invention discloses a realizing method of semi-static dispatching downlink transmission. In the method, eNB only reserves an HARQ process for each user terminal for semi-static dispatching downlink transmission, and binding transmission is carried out on a data packet of semi-static dispatching so as to enable the maximum transportable times of each data packet during a transmission period corresponding to the data packet to be more than or equal to 4. The invention can lower the influence of an HARQ mechanism of semi-static dispatching downlink transmission on LTE downlink peak value speed to be lowest and can save signaling expense of RRC while ensuring normal combination of HARQ, and reduces the complexity of downlink dispatching while ensuring downlink dynamic data transmission speed.

Description

technical field

[0001] The present invention relates to LTE technology, in particular to a method for realizing semi-persistent scheduling downlink transmission. Background technique

[0002] In order to meet the challenges of broadband access technology and to meet the demands of new services, the international standardization organization 3GPP started its long-term evolution (LTE) technology standardization work at the end of 2004.

[0003] The LTE system adopts downlink Orthogonal Frequency Division Multiple Access (OFDMA) and uplink Single Carrier Frequency Division Multiplexing (SC-FDMA) access methods, and introduces Multiple Input Output (MIMO) technology, which greatly improves the The transmission capability of the system effectively resists multipath interference, and can flexibly configure different bandwidths. In the case of 20M bandwidth, the goal of LTE is to achieve the peak transmission rate of uplink 50Mbps and downlink 100Mbps.

[0004] In addition, the e...
