Description

Information indication method, device and system

Technical Field

The present invention relates to the field of communications, and in particular, to an information indication method, apparatus, and system.

Background

Long-Term Evolution (Long-Term Evolution, LTE for short) system, Long-Term Evolution advanced (Long-Term Evolution advanced) system, and international Mobile communication system with international Mobile Telecommunication (IMT-advanced) advanced are based on OFDM (Orthogonal Frequency Division Multiplexing) technology, where OFDM system mainly takes a two-dimensional data form, and in LTE, LTE-a, RB (Resource Block, Physical Resource Block, when mapped on Physical Resource, is defined as OFDM symbol within 1 slot (slot) continuously in time domain, and 12 or 24 subcarriers continuously in Frequency domain, so 1 RB is defined by 1 slot (slot) continuously in time domain, and 1 RB is defined by OFDM (Long-Term Evolution) system, LTE-advanced, and IMT-advanced (international Mobile Telecommunication) system, and OFDM (international Mobile Telecommunication) system

RE (Resource Element), where N_symbIndicating the number of OFDM symbols within 1 slot,

indicating the number of consecutive subcarriers of the resource block in the frequency domain.

The subframe types in the LTE system and the LTE-a system are mainly divided into a unicast subframe for point-to-point transmission and a multicast subframe for point-to-multipoint transmission (each subframe has 2 slots). The Cyclic Prefix type is mainly classified into a normal CP (normal Cyclic Prefix) in which each subframe has 14 OFDM symbols, an extended CP (extended Cyclic Prefix) in which each subframe has 12 OFDM symbols, wherein the OFDM symbol number is numbered from "0", and, for example, "# 0" indicates the 1 st OFDM symbol.

In the related art, if transmission of uplink data fails, uplink synchronous HARQ (Hybrid Automatic Repeat Request) transmission is adopted for uplink data retransmission, and synchronous HARQ means that retransmission subframe positions are agreed in advance at both transmitting and receiving ends, that is, each HARQ process corresponds to a different retransmission subframe position, that is, signaling notification is not required for both the HARQ process and the retransmission subframe position. In addition, in the related art communication system, there are two ways for informing the transmitting end whether the uplink data transmitted by the transmitting end is correctly received by the receiving end: the first is indicated by a PHICH (Physical Hybrid-ARQ Indicator Channel), and the second is indicated by a UL grant (UpLink grant). Specifically, the PHICH transmits only 1-bit or 2-bit DL ACK/NACK (DownLink acknowledgement/negative acknowledgement ), that is, if ACK is transmitted, it indicates that the corresponding uplink data is correctly received, and if NACK is transmitted, it indicates that the corresponding uplink data is incorrectly received, and non-adaptive retransmission is required, where the non-adaptive retransmission indicates that information such as resource allocation and coding modulation level during retransmission is the same as that of first transmission. Specifically, the UL grant not only transmits a New Data Indicator (NDI), but also transmits information such as resource allocation and coding modulation level, that is, if the NDI is flipped compared with the previous transmission of the corresponding HARQ process, it indicates that the corresponding uplink data transmission is newly transmitted, and if the NDI is not flipped compared with the previous transmission of the corresponding HARQ process, it indicates that the corresponding uplink data transmission is adaptive retransmission, where the adaptive retransmission indicates that the information such as resource allocation and coding modulation level is different from the previous transmission during retransmission.

In the related art nr (new radio) system (or referred to as 5G system), there are several typical characteristics as follows: scheduling granularity in the time direction is very flexible; digital, analog, digital plus analog hybrid beam (or called baseband, rf, baseband plus rf hybrid beam) transmission is commonly used at higher carrier frequencies to increase coverage, and the structure of UL self-contained feedback is introduced to reduce delay. Based on the characteristics in the NR system, if uplink synchronous HARQ transmission in LTE and LTE-a systems continues to be used, the synchronous HARQ transmission will limit the flexibility of time granularity and is not suitable for NR-flexible frame structures; the PHICH transmission in a code division mode without considering terminal geography and spatial distribution is not suitable for digital, analog, digital and analog mixed beam transmission; if the UL self-contained approach is applied, too many PHICHs tend to increase the overhead of GP (guard interval). In view of the above problems in the related art, no effective solution has been found at present.
