It is widely believed in the industry that 5G will support higher speed (Gbps), massive links (1M/Km2), ultra-low latency (1ms), higher reliability, and 100 times higher energy efficiency to support new demand changes. For the ultra-low latency index in 5G systems, it is recognized that the user plane delay is 1ms.

The above embodiments will be described below.

The 3rd Generation Partnership Project (3GPP) discusses reducing the TTI length by reducing the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols in a single TTI, for example, 1 ms. The length of the TTI is reduced to 0.5 ms, or even 2 OFDM symbols or the Single Carrier-Frequency Division Multiplexing Access (SC-FDMA) symbol length is reduced, thus the minimum scheduling time is reduced exponentially, and The single transmission delay can be doubled even without changing the frame structure.

When the TTI is reduced to reduce the delay, the TTI lengths corresponding to different channels and/or signals may be different, and the channels and/or signals of different TTI lengths may overlap in the transmission time. There is currently no solution for how to perform channel and/or signal transmission. In the short TTI technology, the user equipment (User Equipment, UE) needs to support a short TTI and a TTI of 1 ms length, and the UE can dynamically switch between the two. When the channel and/or signal of the short TTI and the channel and/or signal of the 1 ms TTI overlap in the transmission time, there is no effective solution for how to perform channel transmission, which is an urgent problem to be solved.

Based on this, when the UCI corresponding to the first transmission time interval and the PUSCH corresponding to the second transmission time interval overlap in the agreed transmission time, the uplink control information UCI corresponding to the first transmission time interval and the solution corresponding to the UCI may be sent. Adjust the reference signal DMRS. The channel corresponding to the second transmission time interval is an uplink traffic channel.

The above embodiments can be applied to a transmitting device. For example, the above sending device may be a UE.

FIG. 3 is a schematic flowchart of an uplink signal sending method provided in this embodiment. As shown in FIG. 3, the method includes the following steps:

In step 302, when the agreed transmission time of the UCI corresponding to the first transmission time interval and the channel corresponding to the second transmission time interval overlap on the agreed transmission time, the target signal is sent, and the second transmission time interval is abandoned or partially transmitted. Information carried by the corresponding channel.

Optionally, the manner of sending the target signal may be at least one of a preset manner and a manner indicated by the base station.

Here, the uplink refers to a direction in which a transmitting device (such as a UE) transmits information to a base station (such as an Evolved NodeB (eNB) or the like).

In step 304, the target signal is transmitted in accordance with the above transmission method.

The target signal includes a UCI corresponding to the first transmission time interval and a demodulation reference signal DMRS corresponding to the UCI.

The transmitting the UCI includes at least one of the following: HARQ-ACK, CSI, and SR.

Optionally, when the UCI corresponding to the first transmission time interval and the channel corresponding to the second transmission time interval have overlapping time on the agreed transmission time, the foregoing step 302 may include: transmitting a target signal;

The channel corresponding to the second transmission time interval is an uplink traffic channel.

In an embodiment, the sending location of the sending target signal may include at least one of: transmitting a DMRS corresponding to the UCI on a first symbol of the overlapping time, in a second of the overlapping time The UCI is transmitted on the symbol.

The following is an example in which the first channel is a physical uplink control channel (PUCCH) corresponding to a short TTI, and the second channel is a physical uplink shared channel (PUSCH) corresponding to a long TTI. Based on the method shown in FIG. 3, the process of transmitting information carried by the channel will be described.

In Embodiments 2 to 5, sTTI is an abbreviation for short TTI, and DMRS, HARQ-ACK, CSI-RS, SR, PUCCH, and UCI corresponding to sTTI are called sDMRS, sHARQ-ACK, sCSI-RS, sSR, sPUCCH, and sUCI. The TTI is an abbreviation of 1 ms TTI, and DMRS, HARQ-ACK, CSI-RS, SR, and PUCCH are all information or channel abbreviations carried on the PUSCH corresponding to the TTI.

Example 2

For example, a carrier is used as an example. When the sUCI and the PUSCH supported by the UE1 overlap on the agreed transmission time, the length of the TTI corresponding to the PUSCH is 1 ms TTI in the Long Term Evolution (LTE) system. The TTI length corresponding to the sUCI includes 2 transmission symbols or 7 transmission symbols. Wherein, 2 transmission symbols or 7 transmission symbols may be physically continuous or discontinuous. 4 is a schematic diagram of overlapping PUSCH and sUCI in the agreed transmission time according to the embodiment. As shown in FIG. 4, UE1 detects an uplink grant in subframe n, and UE1 is to send a PUSCH in subframe n+4. In subframe n+3, UE1 receives the downlink data of sPDSCH again, and needs to send sUCI on n+4 subframes. When the situation shown in Figure 4 occurs, the implementation is as follows:

In this embodiment, the beta indicates that the sHARQ-ACK occupies all the bandwidth resources on the second transmission symbol, and the transmission power is the same as the DMRS or service data usage of the PUSCH.

The sDMRS and sHARQ-ACK information use the same transmit power as the DMRS and data information of the PUSCH, which can reduce the transmission power conversion time of the user. If different transmit powers are used, the first symbol of the first time slot of the PUSCH and the user transmit power of the second symbol increase from at least one of the transition time from on to off and the off time from off to on. This embodiment is capable of transmitting power conversion time, thereby reducing data transmission time and causing interference problems between different conversion powers.

As described in Embodiment 2, the sDMRS on the first symbol can not only demodulate the sHARQ-ACK information but also demodulate the data information on the subsequent PUSCH.

As shown in FIG. 6, the data information of the PUSCH may be transmitted in the second symbol white area of the first slot of the PUSCH.

When the data information of the partial PUSCH is to be transmitted on the second symbol of the first slot of the PUSCH, the interleaving matrix of the second symbol of the first slot of the PUSCH is considered by considering the sHARQ-ACK on the sUCI. The way.

Alternatively, it may be written in a preset manner, such as writing from top to bottom, line by line, or writing from bottom to top, line by line, and the like.

Alternatively, the sHARQ-ACK may be transmitted on all transport blocks of the PUSCH or on one of the 2 transport blocks of the PUSCH. Optionally, the sHARQ-ACK is sent on a transport block with a larger MCS index value. When the MCS index values of the two transport blocks are the same, the sHARQ-ACK may be sent on a preset transport block, for example, sent on the first transport block. Wait.

Alternatively, when transmitting in one transport block of the PUSCH, it may be sent on all layers corresponding to the transport block or on a partial layer. For example, the transmission is repeated on all layers on the transport block of the PUSCH.
