Description

A kind of wireless communications method and device reducing network delay

Technical field

The present invention relates to the transmission plans in wireless communication system, more particularly to the low latency transmission based on Cellular Networks Control channel method and apparatus.

Background technique

In 3GPP (3rd Generation Partner Project, third generation cooperative partner program) RAN (Radio Access Network, wireless access network) in #63 plenary session, reduces the delay of LTE network this project and be discussed.LTE network Delay include eating dishes without rice or wine to postpone, signal processing delay, the transmission delay etc. between node.With wireless access network and core net Upgrading, transmission delay are effectively reduced.With the application for the new semiconductor for having higher height reason speed, signal processing delay It is significantly reduced.

In LTE (LTE-Long Term Evolution, long term evolution), TTI (Transmission Time Interval, Transmission Time Interval) either subframe or PRB (Physical Resource Block, Physical Resource Block) are right (Pair) ms (milli-second, millisecond) is corresponded in time.One LTE subframe includes two time slot (Time Slot)-it is the first time slot and the second time slot respectively.PUCCH (the Physical Upl ink Control of LTE existing system Channel, Physical Uplink Control Channel) it is transmitted in a manner of PRB pair, i.e. a PUCCH transmission occupies one in the time domain Entire LTE subframe.The control information of existing PUCCH transmission includes SR (Scheduling Request, scheduling request), HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat-request) ACK/NACK (confirmation), CSI (Channel State Information, channel state information).Wherein, CSI include again CQI (Channel Quality Indicator, Channel quality instruction), PMI (Precoding Matrix Indicator, pre-coding matrix instruction), RI (Rank Indicator, order instruction), PTI (Precoding Type Indicator, precoding type instruction), CRI (CSI-RS Resource Indicator, CSI reference signal resource instruction).
