Abstract

Provided are a terminal dispatching method and device and a base station. The method is applied in a hybrid automatic repeat request (HARQ) transmission system. The method comprises: receiving an acknowledgement message reported by each dispatching terminal after completing a redundancy version (RV) repeat in the HARQ transmission process; receiving a channel quality indication (CQI) reported by each terminal in a connection state, wherein the terminals include a dispatching terminal in the HARQ transmission process and a to-be-dispatched terminal not in the HARQ transmission process; and according to the acknowledgement message and the CQI, determining the dispatching priority of each terminal, and dispatching each terminal according to the dispatching priority of each terminal. Also provided are a terminal dispatching device and a base station. This embodiment can obtain energy-saving gain resulting from a HARQ transmission mechanism, and achieve the dispatching performance optimization of multi-user dispatching in a HARQ transmission system.

Description

technical field [0001] The present invention relates to communication technology, in particular to a terminal scheduling method, device and base station. Background technique [0002] Hybrid Automatic Repeat Request (HARQ) technology, as a key technology of modern wireless communication, provides a strong guarantee for reliable transmission of wireless data, and has been used in High Speed ​​Downlink Packet Access (High Speed ​​Downlink Packet Access; hereinafter referred to as: HSDPA) and long term evolution (Long Term Evolution; hereinafter referred to as: LTE) have been widely used. HARQ can be divided into three types from the implementation mechanism. The first type of HARQ (HARQType I) is also called traditional ARQ. The receiving end first corrects the error of the data packet. If there is an error that cannot be corrected, it sends a data packet retransmission request and discards it Wrong data packets, use the same forward error correction code when retransmitting,...
