Description

A kind of wireless communications method and device for reducing network delay

Technical field

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

Background technology

At 3GPP (3rd Generation Partner Project, third generation cooperative partner program) In RAN (Radio Access Network, wireless access network) #63 plenary session, LTE is reduced The delay of network this problem comes into question.The delay of LTE network includes eating dishes without rice or wine to postpone, signal transacting Time delay, the transmission delay between node etc..With the upgrading of wireless access network and core net, transmission Time delay is can be effectively reduced.With the application of the new semiconductor for possessing higher height reason speed, signal Treatment time delay is significantly reduced.

In LTE (LTE-Long Term Evolution, Long Term Evolution), TTI (Transmission Time Interval, Transmission Time Interval) or subframe or PRB (Physical Resource Block, Physical Resource Block) (Pair) is corresponded in time ms (milli-second, Millisecond).One LTE subframe includes two time slots (Time Slot)-be respectively the first time slot With the second time slot.LTE existing systems PUCCH (Physical Upl ink Control Channel, Physical Uplink Control Channel) be transmitted in the way of PRB pairs, i.e., one PUCCH transmission when A whole LTE subframes are occupied on domain.The control information of existing PUCCH transmission includes SR (Scheduling Request, dispatch request), HARQ (Hybrid Automatic Repeat ReQuest, hybrid automatic repeat-request) ACK/NACK (confirmation), CSI (Channel State Information, channel condition information).Wherein, CSI includes CQI (Channel Quality again Indicator, channel quality indicate), (Precoding Matrix Indicator, prelist PMI Code matrix is indicated), RI (Rank Indicator, exponent number indicate), PTI (Precoding Type Indicator, precoding type indicate), CRI (CSI-RS Resource Indicator, CSI Reference signal resource is indicated).
