Embodiment 1

[0168] like figure 1 As shown, the information sending method described in Embodiment 1 of the present invention includes:

[0169] S110. Determine a first transmission resource for scheduling SA signaling and a second transmission resource for data DATA in the information to be transmitted; where the frequency band where the first transmission resource is located is lower than or equal to the frequency band where the second transmission resource is located;

[0170] S120. Send information to be sent according to the first sending resource and the second sending resource.

[0171] In the information transmission method described in Embodiment 1 of the present invention, 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 to obtain higher reliability. and coverage distance; send DATA on a higher frequency band to obtain frequency ...

Embodiment 2

[0217] combine Figure 5 , the information sending method described in Embodiment 2 of the present invention, comprising:

[0218] S510, determining to be used in the information to be sent, selecting at least one resource in the SA configuration resource pool as the first transmission resource for SA signaling transmission, and selecting at least one resource in the DATA configuration resource pool as the second transmission resource for DATA transmission ; Wherein, the frequency band where the first transmission resource is located is lower than or equal to the frequency band where the second transmission resource is located;

[0219] S520. Send information to be sent according to the first sending resource and the second sending resource.

[0220] Using this embodiment, during the resource selection process when the terminal sends services, it selects transmission resources for SA signaling and DATA from the SA configuration resource pool and DATA configuration resource po...

Embodiment 3

[0268] combine Figure 8 , the information sending method described in Embodiment 3 of the present invention, comprising:

[0269] S810, select at least one resource in the SA configuration resource pool as the first transmission resource for SA signaling;

[0270] S820. Determine a second transmission resource for DATA transmission according to the preset correspondence between the SA configuration resource and the DATA configuration resource and the first transmission resource;

[0271] S830. Send information to be sent according to the first sending resource and the second sending resource.

[0272] Using this embodiment, in the resource selection process when the terminal transmits services, in the case that the transmission resources of SA signaling and the transmission resources of DATA have a preset corresponding relationship, the selection of SA resources is prior to the selection of DATA resources in sequence, and before the selection of DATA resources according to ...

Abstract

The invention provides an information sending method and a terminal. The method comprises the following steps: determining a first sending resource for scheduling SA signaling and a second sending resource for data DATA in to-be-sent information, wherein the frequency band where the first sending resource is located is lower than or equal to the frequency band where the second sending resource islocated; and sending the to-be-sent information according to the first sending resource and the second sending resource. The method can solve the problems that in a V2X communication protocol in the prior art, SA and data are usually sent on one frequency band, the bandwidth is insufficient when low-frequency-band frequency domain resources are adopted, the coverage performance of high-frequency-band frequency domain resources is limited, and the high data transmission rate and the high coverage range and coverage distance of SA cannot be guaranteed at the same time.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to an information sending method and a terminal. Background technique [0002] 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 transmitted on each time domain resource is 31704bit, that is, 3963byte. In 3GPP Release 15, carrier aggregation is used to increase the peak rate of data transmission and supports a maximum of 8 carriers. However, it is still difficult to significantly increase the data transmission rate in the case of limited frequency domain resource bandwidth. [0003] Therefore, it is planned to increase the data transmission rate by using frequency domain resources in higher frequency bands, such as 30GHz frequency band and 63-64GHz frequency band, to obtain greater bandwidth. However, as the frequency increases, the covera...
