Description

Information transmission method and terminal

The present invention belongs to the field of wireless technology, and in particular relates to an information sending method and a terminal.

In the vehicle-to-everything (V2X) communication protocol of 3GPP Release 14, UE (User Equipment) only supports single-carrier transmission, and the maximum service payload that can be sent on each time domain resource is 31704bit, that is, 3963byte . While 3GPP Release 15 studies to increase the peak rate of data transmission through carrier aggregation, and supports a maximum of 8 carriers, it is still difficult to significantly increase the data transmission rate when the bandwidth of frequency domain resources is limited.

Therefore, it is proposed to increase the data transmission rate by using the frequency domain resources of higher frequency bands to obtain a larger bandwidth, such as the 30GHz frequency band and the 63-64GHz frequency band. However, as the frequency increases, the coverage performance of the signal decreases.

The transmission of the V2X service package includes two parts: Scheduling Assignment (SA) signaling and data DATA. SA is used to indicate DATA-related transmission parameters, including service priority, time-frequency resources, retransmission times, adjustment and coding methods. The role of SA includes not only instructing the receiving user terminal UE to perform receiving and decoding, but also instructing the receiving UE to perform corresponding measurements (such as Reference Signal Receiving Power (RSRP)), so as to determine the information The source occupancy status is used for the 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 in the same frequency band. When this method is adopted, in order to meet the requirements of higher coverage and distance of SA transmission, it is usually necessary to reduce the frequency of SA transmission. However, the reduction of the frequency will cause data transmission. Therefore, it is impossible to meet the higher data transmission rate requirements while ensuring that SA has a higher coverage and coverage distance.

The purpose of the present invention is to provide an information sending method and terminal, which are used to solve the problem that the resource allocation method in the related art cannot simultaneously guarantee a higher data transmission rate and a higher coverage range and coverage distance of the SA.

The information sending method according to the specific embodiment of the present invention can solve the problem that in the related art V2X communication protocol, SA and data are usually sent in one frequency band, and the low-frequency frequency domain resources are insufficient in bandwidth and the high-frequency frequency domain resources have limited coverage performance, which cannot be At the same time, the problem of ensuring higher data transmission rate and higher coverage and coverage distance of SA.

Example 1

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

Embodiment 1 of the present invention In the information sending method, the first sending resource used for SA signaling sending is lower than or equal to the second sending resource used for DATA sending, so that SA is sent on a lower frequency band to obtain higher reliability and coverage distance; send DATA on a higher frequency band to obtain frequency domain resources with a larger bandwidth, thereby solving the problem of insufficient bandwidth of low-frequency frequency domain resources and limited coverage performance of high-frequency frequency domain resources, which cannot guarantee higher data transmission at the same time. Rate and SA's higher coverage and coverage distance.

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

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

Among them, in the PC5 V2X signal, no dedicated AGC measurement area is introduced, and the AGC measurement is performed through the first symbol of the subframe. 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 (Orthogonal Frequency Division Multiplexing, OFDM) symbol is lost when the D2D state transition occurs.

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

Here, for PSBCH (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 used to carry data; entities such as encoding, rate matching, interleaving, etc. The layer processing mechanism is the same as D2D; 2) PSCCH (Physical Sidelink Control Channel): Used to carry 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 errors caused by discarding the first and last symbols. The generation of PSSS is the same as that of D2D, and SSSS adopts the SS sequence of LTE subframe 5.

In addition, in the V2X protocol, the resource pool configuration of SA and data includes two types: adjacent band and non-adjacent band. Specifically as shown in Figure 4a and Figure 4b:

1) For the adjacent band configuration mode, SA and associated data are sent in adjacent bands of the same subframe, SA and associated data resources are sent in the same subframe, and the two are adjacent in the frequency domain.

2) For the non-adjacent band mode, the SA and associated data are sent in the non-adjacent band of the same subframe. SA and data use independent entity resources, and the two do not overlap in the frequency domain.
