Description

Information sending and receiving method and device, terminal and base station

Technical Field

The disclosure relates to the field of communication, and in particular, to an information sending and receiving method and device, a terminal and a base station.

Background

With the advent of industrial automation, networking, remote control, smart grids, virtual reality and other emerging services, higher requirements are put on the time delay of the wireless communication system carried by the system. Such as requiring a 1ms or even 0.5ms air interface delay. Therefore, the third generation partnership project (3 rd Generation Partnership Project, abbreviated as 3 GPP) is gradually developing researches on low latency related issues based on long term evolution (Long Term Evolution, abbreviated as LTE)/long term Advanced (LTE-Advanced, abbreviated as LTE-a) systems and new generation, i.e., fifth generation, mobile communication systems (5G), respectively.

In an LTE/LTE-a system, a transmission time interval (Transmission Time Interval, abbreviated TTI) is a basic unit of downlink and uplink transmission scheduling in the time domain. As in a frequency division duplex (Frequency Division Duplex, FDD) system, the time dimension is divided into radio frames of length 10ms, where each radio frame includes 10 subframes with a TTI length equal to the subframe length of 1ms. Each subframe includes two slots, each of which has a length of 0.5ms. Each downlink time slot contains 7 orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, abbreviated OFDM) symbols (6 OFDM symbols under extended cyclic prefix); each uplink slot contains 7 Single Carrier frequency division multiplexing (SC-FDMA) symbols (6 SC-FDMA symbols under the extended cyclic prefix).

In 5G systems, more flexible frame structure support is needed to support new demand changes such as higher rates, massive links, ultra low latency, higher reliability, hundred times energy efficiency improvement, etc. A transmission time unit (slot) shorter than the LTE/LTE-a time domain length is primarily defined in the current standard. For faster downlink hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, abbreviated HARQ), self-contained feedback needs to be implemented if necessary, where there may be only one or two time domain symbols for the uplink control symbol.

However, in order to maintain the single carrier characteristic of the uplink signal to support better uplink coverage and power amplifier efficiency, the uplink Reference Signal (RS) in the prior art should monopolize one time domain Symbol, and when the number of time domain symbols included in the uplink control channel (Physical Uplink Control Channel, PUCCH) is small, the RS overhead is too large. E.g. its RS overhead would reach 50% for a two symbol PUCCH. And the RS overhead in the PUCCH Format 3 for transmitting the large-load uplink control information in the LTE/LTE-A system is 2/7, and the RS overhead in the PUCCH Format 4/5 is only 1/7. Therefore, there is currently a lack of a method for reducing RS overhead when transmitting heavy-duty uplink control information.

In view of the above technical problems, no effective solution has been proposed at present.

Preferred embodiment 1

Fig. 8 is a schematic diagram of transmitting uplink control information within 2 RBs of two symbol frequency domain in the time domain according to the preferred embodiment 1 of the present disclosure, as shown in fig. 8, after the uplink control information is encoded and QPSK modulated, 30 modulation symbols are output in total, and the results (X0, X1, X2, …, X22, X23) of the last 24 modulation symbols after 24-point DFT are mapped on 24 consecutive subcarriers of the second time domain symbol in sequence. This preferred embodiment assumes that there are 2 time domain symbols, 1 of which is the predefined symbol containing both RS and data, m=2 frequency domain units in the frequency domain over the predefined symbol, nsc=12 subcarriers in each frequency domain unit, k=2 packets in the frequency domain unit, a group with index (0,2,4,6,8,10), and a group with indices (1, 3,5,7,9, 11).

In fig. 8, the results (A0, A1, A2, A3, A4, A5) of the first 6 modulation symbols after 6-point DFT are multiplied by 1 and then phase-rotated by-1, and mapped sequentially into 2 frequency-domain units, that is, RB0, and the sub-carrier indexes in RB1 are (1, 3,5,7,9, 11) packets. That is, in fig. 8, 6 data information samples (A0, A1, A2, A3, A4, A5) are sequentially mapped on subcarriers in a group having a group index k=1 in a frequency domain unit (RB 0) having an index m=0, that is, subcarriers having subcarrier indexes (1, 3,5,7,9, 11); the 6 data information samples are mapped on subcarriers of index (1, 3,5,7,9, 11) of frequency domain unit (RB 1) with index m=1 through phase rotation result of-1, i.e., (-A0, -A1, -A2, -A3, -A4, -A5).

In fig. 9, the uplink control information is encoded, scrambled, and QPSK modulated, and then outputs 57 modulation symbols in total, and the 48 modulation symbols are subjected to 48-point DFT to sequentially map the results (X0, X1, X2, …, X46, X47) on 48 consecutive subcarriers of the second time domain symbol. This embodiment assumes that the present disclosure contains 2 time domain symbols, 1 of which is the predefined symbol containing both RS and data, m=4 frequency domain units are contained in the frequency domain on the predefined symbol, nsc=12 subcarriers are contained in each frequency domain unit, k=4 packets are contained in each frequency domain unit, and the indexes of the subcarriers contained in each group are (0, 4, 8), (1, 5, 9), (2, 6, 10), (3, 7, 11), respectively.

In fig. 9, the 9 modulation symbols of the output modulation symbols are subjected to three groups of 9-point DFT in which the results (A0, B0, C0, A1, B1, C1, A2, B2, C2) are mapped in 4 frequency domain units of a predetermined time domain symbol with a certain phase offset. That is, in fig. 9, (A0, A1, A2) is multiplied by 1, and phase rotation, and then mapped sequentially into four frequency domain units, that is, groups of (0, 4, 8) subcarrier indexes in RB0, RB1, RB2, RB 3; multiplying (B0, B1, B2) by 1, -1, and sequentially mapping the phase rotations into groups with subcarrier indexes (2, 6, 10) in four frequency domain units, namely RB0, RB1, RB2 and RB 3; multiplying (C0, C1, C2) by 1, j, -1, -j, and sequentially mapping the phase rotations to the four frequency domain units, namely, the groups with subcarrier indexes (3, 7, 11) in RB0, RB1, RB2 and RB 3;

likewise, the defined 3 reference signal RS samples (R0, R1, R2) are mapped on predetermined time domain symbols. Multiplying 3 RS sample points by 1, -j, -1, j respectively in a preset time domain symbol, and sequentially mapping the 3 RS sample points into groups with subcarrier indexes of (1, 5, 9) in four frequency domain units, namely RB0, RB1, RB2 and RB3 after phase rotation;

at this time, the predetermined time domain symbol is transmitted after performing 48-point IFFT operation, and at this time, the reference symbol information corresponds to a sample with an index of 4n+1 in the time domain and does not overlap with the data information in the time domain. Therefore, the transmitting method of the embodiment not only realizes that the RS and the modulation data symbol are transmitted on the same time domain symbol, but also can ensure that the better peak-to-average ratio is achieved.

This embodiment assumes that the present disclosure contains 2 time domain symbols, 1 of which is the predefined symbol containing both RS and data, m=2 frequency domain units in the frequency domain on the predefined symbol, nsc=24 subcarriers, i.e. 2 RBs, in each frequency domain unit, k=2 packets in the frequency domain unit, one group with indices (0, 2,4, …,18,20, 22), and one group with indices (1, 3,5, …,19,21, 23).

That is, in fig. 10, (R0, R1, R2, …, R9, R10, R11) are sequentially multiplied by 1,1 phase rotations, and then sequentially mapped into a packet with subcarrier indexes (0, 2,4, …,18,20, 22) in 2 frequency domain units.

The predetermined time domain symbol is transmitted after 48-point IFFT operation, and the reference symbol information is corresponding to a sample with an index of 2n in the time domain and does not overlap with the data information in the time domain. Therefore, the transmitting method of the embodiment not only realizes that the RS and the modulation data symbol are transmitted on the same time domain symbol, but also can ensure that the better peak-to-average ratio is achieved.
