Information transmission method and terminal

Cross-reference to related applications

The present application claims priority to Chinese Patent Application No. 201 810 135 313 8.0 filed on Jan. 9, 2018, the entire content of which is hereby incorporated by reference.

Technical field

The present disclosure relates to the field of wireless technologies, and in particular, to an information sending method and a terminal.

Background technique

In the protocol of the vehicle to the (Vehicle to X, V2X) communication of the 3GPP Release 14, the UE (User Equipment) only supports single-carrier transmission, and the maximum service payload payload that can be transmitted on each time domain resource is 31,704 bits, that is, 3,963 bytes. . 3GPP Release 15 studies the peak rate of data transmission through carrier aggregation, and supports up to 8 carriers. However, in the case of limited bandwidth in the frequency domain, it is still difficult to significantly increase the data transmission rate.

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

The sending of the V2X service packet includes 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, adjustment, and coding mode. The role of the SA includes the indication that the receiving user terminal UE performs the reception decoding, and the indication that the receiving UE performs the corresponding measurement (such as the Reference Signal Receiving Power (RSRP)), thereby determining the resource occupation status and using it for other UEs. The instructions before the 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 one frequency band. In this mode, in order to meet the requirement of the SA to send a higher coverage and coverage distance, it is usually required to reduce the frequency of SA transmission. However, the frequency reduction causes data transmission. The bandwidth is reduced, resulting in a lower data transmission rate, so that the SA has a higher coverage and coverage distance while meeting the higher transmission rate requirements of the data.

Equipment, etc.

The method for transmitting information according to the specific embodiment of the present disclosure can solve the related technology. In the V2X communication protocol, the transmission of SA and data is usually in one frequency band, and the bandwidth of the low-frequency frequency domain resource is insufficient, and the coverage of the high-frequency frequency domain resource is limited. At the same time, the problem of higher data transmission rate and higher coverage and coverage distance of SA is ensured.

Embodiment 1

As shown in FIG. 1, the information sending method according to Embodiment 1 of the present disclosure includes:

S110. Determine a second sending resource, where the first sending resource and the data DATA are used for scheduling the SA signaling, where the frequency of the first sending resource is lower than or equal to the frequency band of the second sending resource.

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

In the information sending method of the first embodiment of the present disclosure, the first sending resource used for the SA signaling is lower than or equal to the second sending resource used for the DATA sending, so that the SA is sent in the lower frequency band to obtain a higher reliability. Sex and coverage distance; DATA is transmitted on a higher frequency band to obtain a larger bandwidth frequency domain resource, thereby solving the problem that the low frequency band frequency domain resource bandwidth is insufficient, the high frequency band frequency domain resource coverage performance is limited, and the high data transmission rate cannot be guaranteed at the same time. And SA's higher coverage and coverage distance issues.

The information transmitting method according to the embodiment of the present disclosure is applied to a terminal of a V2X communication of a vehicle network. Due to a relatively high relative moving speed of the vehicle network, the carrier frequency can reach 6 GHz, so the correlation time of the received signal becomes shorter, and the pilot time of the channel is The domain interval needs to be shortened. Further, an additional frequency offset is introduced in the synchronization process. Therefore, in each subframe of the PC5V2X, four pilot symbols are needed, and the specific pilot symbol positions are (2, 5, 8, 11) positions, as shown in the figure. 2 is shown.

It should be noted that the frame structure of the PC5V2X follows the basic design of the D2D frame structure. The length of the TTI (Transmission Time Interval) is 1 ms, and one TTI includes two slots. The first symbol of the subframe is used to carry the service. Data, the receiving end performs AGC (Automatic Gain Control) adjustment on the symbol. The last symbol of the subframe is used as the GP, and the GP uses the method of puncture to perform mapping of the RE (Resource Element).

Wherein, in the PC5V2X signal, a dedicated AGC measurement area is not introduced, wherein the measurement of the AGC is performed by the first symbol of the subframe, so that no additional mechanism is introduced in the standard, and the resource overhead of the fixed AGC is not required, only An Orthogonal Frequency Division Multiplexing (OFDM) symbol is lost when state transition occurs in D2D.

It should be noted that in the PC5V2X system, since the coverage radius target is only 300 meters, the LTE conventional CP length, that is, the regular CP length, can be satisfied to meet the system coverage requirement.

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

It should be noted that in the PC5V2X system, there are three types of physical channels:

1) PSSCH (Physical Sidelink Shared Channel): a channel used to carry data; the physical layer processing mechanism such as coding, rate matching, and interleaving is the same as D2D;

2) PSCCH (Physical Sidelink Control Channel): used to carry control information channels, SA signaling; physical layer processing mechanisms such as coding, rate matching, and interleaving are the same as D2D;

3) PSBCH (Physical Sidelink Broadcast Channel): used for synchronous control and adjustment. Compared with D2D, 8 bits are added as a reservation to avoid the decoding error caused by the first and last symbols. The PSSS is generated in the same manner as the D2D, and the SSSS uses the SS sequence of the LTE subframe 5.

In addition, in the V2X protocol, the resource pool configuration of the SA and the data includes two types: the neighboring band and the non-neighboring band. In the configuration of the resource pool, the resource pool configuration method is defined for the transmission mode of the adjacent band and the non-neighboring band respectively. Specifically as shown in Figure 4a and Figure 4b:

1) For the neighboring band configuration mode, the SA and the associated data are transmitted in the neighboring zone of the same subframe, and the SA and the associated data resource are transmitted in the same subframe, and the two are adjacent in the frequency domain.

2) For the non-neighboring mode, the SA and the associated data are transmitted in the non-neighboring band of the same subframe. SA and data use independent physical resources, and the two do not overlap in the frequency domain. From the user level, the SA and associated data are also frequency division multiplexed, and the SA is in the same subframe as the indicated Data resource.

According to the information sending method in the specific embodiment of the present disclosure, in step S110, the first sending resource and the second sending resource are determined according to the SA configuration resource pool and/or the DATA configuration resource pool.

1) the frequency in the first frequency range is less than the preset value, and the frequency in the second frequency range is greater than or equal to the preset value;

2) the frequency in the first frequency range is less than the preset value, and the second frequency range includes the first frequency range;

3) the first frequency range includes a second frequency range, and the frequency in the second frequency range is greater than or equal to a preset value;

4) The first frequency range is the same as the second frequency range.

In a specific embodiment of the present disclosure, the preset value is 6 GHz, wherein a frequency band with a frequency less than 6 GHz can be regarded as a low frequency band, and a frequency band with a frequency greater than or equal to 6 GHz can be regarded as a high frequency band.

In the first configuration, the resource pool configuration is configured for the SA in the low frequency band, and the resource pool is configured only for the DATA in the high frequency band. Therefore, when the information is sent, the frequency of the SA signaling transmission resource is lower than the DATA.

And the data resource pool is configured independently.

With configuration (as shown in Figure 4b) and / or independent configuration. That is, the high-band SA resource pool and the DATA resource pool are configured in a neighboring manner; and/or the high-band SA resource pool and the data resource pool are configured in a non-neighbor mode; and/or, the high-band SA resource pool And the data resource pool is configured independently.

The configuration of the resource pool can be configured for the SA in the low frequency band and the high frequency band, and the resource pool configuration can be configured for the data in the low frequency band and the high frequency band respectively.

Optionally, in this manner, the resource configured in the first frequency range and the resource configured in the DATA configuration resource pool in the SA configuration resource pool are in a neighboring configuration mode, a non-neighbor configuration, and/or an independent manner. The configuration mode, and the resources configured in the second frequency range and the resources configured in the DATA configuration resource pool in the SA configuration resource pool are in the neighbor configuration mode, the non-neighbor configuration mode, and/or the independent configuration mode. That is, specifically, the low-band SA resource pool and the data resource pool are configured in a neighboring manner; and/or the low-band SA resource pool and the data resource pool are configured in a non-neighboring manner; and/or a low-band SA resource pool and data The resource pool is configured in an independent manner; and/or the high-band SA resource pool and the data resource pool are configured in a neighboring manner; and/or the high-band SA resource pool and the data resource pool are configured in a non-neighbor mode; and/or a high-band SA The resource pool and data resource pool are configured independently.
