Description

Information indicating method and device, system

Technical field

The present invention relates to the communications field, in particular to a kind of information indicating method and device, system.

Background technology

Long Term Evolution (Long-Term Evolution, referred to as LTE) system, advanced long-term evolution system (Long- Term Evolution Advance, referred to as LTE-Advance) system, IMT-Advanced (International Mobile Telecommunication Advanced) advanced ternational Mobile Telecommunications system is all with OFDM (Orthogonal Frequency Division Multiplexing, OFDM) based on technology, in an ofdm system mainly when The data mode of frequency bidimensional, RB (Resource Block, the resource block in LTE, LTE-A；Resource block mapping is on physical resource Then it is referred to as Physical Resource Block, Physical Resource Block) it is defined as in time-domain in continuous 1 slot (time slot) OFDM symbol, continuous 12 or 24 subcarriers in frequency domain, thus 1 RB byIndividual RE (Resource Element, resource unit), wherein N_symbThe number of the OFDM symbol in 1 slot is represented,Represent resource block in frequency domain The number of upper continuous subcarrier.

Subframe type is broadly divided into unicast sub-frame and point-to-multipoint for point-to-point transmission in LTE system, lte-a system The multicast subframe (each subframe totally 2 time slots) of transmission.Cyclic prefix type is broadly divided into normal CP (normal Cyclic Prefix, normal cyclic prefix), now each subframe totally 14 OFDM symbols, extended CP (extended Cyclic Prefix, extended cyclic prefix), now since " 0 " compile by totally 12 OFDM symbols, wherein OFDM symbol sequence number for each subframe Number, such as " #0 " represents the 1st OFDM symbol.

In the related art, if upstream data bust this, uplink data retransmission is using uplink synchronous HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) transmits, and synchronous HARQ means to retransmit subframe Position is that transmitting-receiving two-end is appointed in advance, i.e., each HARQ process correspond to different re-transmission subframe positions, that is, Say or HARQ process, re-transmission subframe position need not signal.In addition, in the communication system of correlation technique, notice hair Penetrating the upstream data of end transmitting, whether receiving end receives correct mode two kinds：First, pass through PHICH (Physical Hybrid-ARQ Indicator Channel, Physical HARQ Indicator Channel) instruction, second, passing through UL grant (UpLink Grant, uplink grant information) instruction.Specifically, PHICH only transmits 1bit or 2bits DL ACK/NACK (DownLink Acknowledge/Nacknowledge, downlink acknowledgments/unacknowledged information), i.e., the table if ACK is transmitted Upstream data receives correctly corresponding to bright, shows that corresponding upstream data receives mistake, it is necessary to carry out non-if NACK is transmitted It is identical that adaptive retransmission, wherein non-self-adapting retransmit the information such as resource allocation, coded modulation grade and first biography when representing to retransmit.Tool Body, UL grant not only transmit NDI (New data indicator, new data instruction), and also transfer resource distribution, coding are adjusted The information such as grade processed, i.e., if NDI is overturn compared with once being transmitted before corresponding HARQ instance process, then show correspondingly Transmitting uplink data be new biography, if NDI with before corresponding HARQ instance process once transmit compared with do not overturn, show Corresponding transmitting uplink data is adaptive retransmission, resource allocation, coded modulation grade when wherein adaptive retransmission represents to retransmit It is different with transmission before etc. information.

In NR (New Radio) system (or being 5G systems) of correlation technique, there is the characteristics of following several typical：When Between granularity is dispatched on direction is very flexible；Usually using numeral, simulation, digital added analogue in higher carrier frequency The transmission means of mixed-beam (or adding radio frequency mixed-beam for base band, radio frequency, base band) improves coverage, in order to reduce Time delay introduces the structure of UL self-contained feedbacks.The characteristics of based in above-mentioned NR systems, if continue to continue to use LTE, Uplink synchronous HARQ transmission in lte-a system, synchronous HARQ transmit the flexibility that will limit time granularity, are not suitable for NR Flexible frame structure；Do not consider terminal geographic, spatial distribution code division mode under PHICH transmission be not suitable for numeral, simulation, number Word adds simulation mixed-beam transmission；If using UL self-contained modes, excessive PHICH certainly will add GP and (protect Shield interval) expense.For above mentioned problem present in correlation technique, at present it is not yet found that the solution of effect.
