Description

Information sending method and terminal

The present invention belongs to the field of wireless technology, and more particularly, to a method and terminal for transmitting information.

In the 3GPP Release 14 Vehicle to X (V2X) communication protocol, the UE (User Equipment) only supports single carrier transmission. The maximum service payload payload that can be sent on each time domain resource is 31704bit, which is 3963byte. . And 3GPP Release 15 studies to increase the peak data transmission rate through carrier aggregation. It supports a maximum of 8 carriers, but it is still difficult to significantly increase the data transmission rate in the case of limited bandwidth in the frequency domain.

Therefore, it is planned to increase the data transmission rate by using higher frequency band resources and gaining greater bandwidth, such as 30GHz band and 63-64GHz band. However, as the frequency increases, the coverage performance of the signal decreases.

The sending of V2X service packets includes two parts: Scheduling SA (Scheduling Assignment) signaling and data DATA. The SA is used to indicate DATA-related transmission parameters, including service priority, time-frequency resources, retransmission times, adjustments, and coding methods. The role of SA includes not only instructing the receiving user terminal UE to perform reception decoding, but also instructing the receiving UE to perform corresponding measurements (such as Reference Signal Receiving Power (RSRP)) to determine the information The source occupancy condition is used as an indication before other UEs perform resource selection. Therefore, SA coverage and reliability need to be higher than data.

In the related art, the transmission of SA and data is usually on a frequency band. In this method, in order to meet the requirements of higher coverage and coverage distance of SA transmission, it is usually necessary to reduce the frequency of SA transmission. However, the reduction of frequency will cause data transmission. The reduction in bandwidth results in a reduction in data transmission rate. Therefore, it is not possible to meet the higher data transmission rate requirements while ensuring that SA has a high coverage and distance.

The information sending method according to the specific embodiment of the present invention can solve the related art V2X communication protocol. The transmission of SA and data is usually on one frequency band. The low-band frequency-domain resource bandwidth is insufficient, and the high-band frequency-domain resource coverage performance is limited. At the same time, the problems of higher data transmission rate and higher SA coverage and coverage distance are guaranteed.

Example one

As shown in FIG. 1, the method for transmitting information according to the first embodiment of the present invention includes: S110, determining a first transmission resource for scheduling SA signaling and a second transmission resource for data DATA in the information to be transmitted; The frequency band in which the transmission resource is located is lower than or equal to the frequency band in which the second transmission resource is located; S120: Send the information to be transmitted according to the first transmission resource and the second transmission resource.

According to the first embodiment of the present invention, the information transmission method includes that the first transmission resource used for SA signaling transmission is lower than or equal to the second transmission resource used for DATA transmission, so as to transmit SA on a lower frequency band and obtain higher reliability. And coverage distance; send DATA on higher frequency bands to obtain greater bandwidth frequency-domain resources, thereby addressing insufficient bandwidth in low-band frequency domain resources and limited coverage performance in high-band frequency domain resources, which cannot guarantee higher data transmission at the same time Speed and SA coverage issues and coverage distance issues.

According to the embodiment of the present invention, the information sending method is applied to a V2X communication terminal of the Internet of Vehicles. Due to the relatively high moving speed of the Internet of Vehicles, the carrier frequency can reach 6 GHz, so the correlation time of the received signal becomes shorter, and the channel's pilot time domain The interval needs to be shortened. Further, an additional frequency offset is introduced in the synchronization process. Therefore, under each sub-frame of the PC5 V2X, four pilot symbols are required, and the specific pilot symbol position is (2,5,8,11). as shown in picture 2.

It should be noted that the frame structure of the PC5 V2X follows the basic design of the D2D frame structure. The length of the TTI (Transmission Time Interval) is 1ms. One TTI contains two time slots, and the first symbol of the sub frame. It is used to carry service data. The receiver performs AGC (Automatic Gain Control) adjustment on this symbol. The last symbol of the sub-frame is used as the GP, and the GP uses the punctuation method to map the RE (Resource Element, resource unit).

Among them, in the PC5 V2X signal, no dedicated AGC measurement area is introduced. The AGC measurement is performed by the first symbol of the sub-frame. In this way, no additional mechanism is introduced in the standard, and no fixed AGC resource overhead is required. Only one Orthogonal Frequency Division Multiplexing (OFDM) symbol is lost when D2D state transition occurs.

It should be noted that, in the PC5 V2X system, since the coverage radius target is only 300 meters, it supports the LTE conventional CP length, that is, the conventional CP length, which can meet the system coverage requirements.

Here, for a PSBCH (Physical Direct Link Broadcast Channel, Physical Sidelink Broadcast Channel), the number of occupied pilot symbols is 3, and the occupied positions are symbols 4, 6, and 9, as shown in FIG. 3.

It should be noted that in the PC5 V2X system, there are three types of physical channels: 1) PSSCH (Physical Sidelink Shared Channel): a channel for carrying data; encoding, rate matching, interleaving and other entities The layer processing mechanism is the same as D2D; 2) PSCCH (Physical Sidelink Control Channel): It is used to carry the control information channel, SA signaling; coding, rate matching, interleaving and other physical layer processing mechanisms are the same as D2D; 3) PSBCH (Physical Sidelink Broadcast Channel): used for synchronization control and adjustment. Compared with D2D, 8 bits are added as a reservation to avoid decoding error problems caused by knocking out the head and tail symbols. The generation of PSSS is the same as that of D2D. The SSSS uses the SS sequence of LTE sub frame 5.

In addition, in the V2X protocol, the resource pool configuration of SA and data includes two types of adjacent and non-adjacent bands. In the configuration of the resource pool, the method of resource pool configuration is defined for the transmission methods of adjacent and non-adjacent bands. As shown in Figure 4a and Figure 4b:
