detailed description

In the LTE system, after the first communication device is powered on, it receives the primary synchronization signal (PSS) at several center frequency points where there may be LTE cells, and judges whether there may be cells around the frequency points based on the received signal strength. The first communication device stores the frequency and operator information when it was powered off last time, and then searches for the last cell it resided in after powering on; if not, it scans the entire frequency band within the frequency band allocated to the LTE system. The first communication device detects the PSS around the center frequency point of the frequency band, and the PSS occupies 6 physical resource blocks (Physical Resource Block, PRB) of the center frequency band, and repeats with a period of 5ms. By detecting the PSS terminal, the cell ID in the cell group can be obtained, and the time slot boundary of 5ms can be determined at the same time. Duplex, FDD) or Time-division Duplex (TDD)). After 5ms time slot synchronization, the first communication device will search for Secondary Synchronization Signals (SSS) forward on the basis of PSS. Only one SSS can determine the boundary of 10ms, which achieves the purpose of frame synchronization. Since the SSS signal carries the cell group ID, it can be combined with the PSS to obtain the physical layer ID (cell ID), and further obtain the configuration information of the downlink reference signal. Since both PSS and SSS are sent on the 6 RBs in the middle of the system bandwidth and are sent symmetrically within the bandwidth, frequency synchronization can also be obtained by detecting PSS and SSS terminals. After obtaining frame synchronization, frequency synchronization and downlink reference signal configuration, the terminal further detects the downlink reference signal to obtain accurate time slot and frequency synchronization, and then reads the physical broadcast channel (PBCH) of the broadcast channel PBCH to obtain the system Frame number, bandwidth information, configuration of Physical Hybrid ARQ Indicator Channel (PHICH), and basic system configuration information such as antenna configuration, so as to achieve synchronization with the cell.

The PSS, SSS and PBCH in the NR system form a synchronization signal block (Synchronization Signal and Physical broadcast channel block, SSB). The NR system defines the possible time-frequency positions of the SSB. The first communication device will try to search for the SSB during the synchronization process. , the SSB carries the index information of the SSB, and the index corresponds to the position of the SSB in the radio frame one-to-one. Therefore, after obtaining the SSB index, the position of the SSB in the radio frame can be determined, thereby determining the frame boundary of the radio frame and realizing the frame boundary of the radio frame. Synchronize. Specifically, the first communication device first obtains timing synchronization according to the PSS and the SSS, and then the terminal further detects the PBCH, and the information carried by the PBCH includes MIB information and 8-bit physical layer information. The physical layer information includes SFN, field indication, SSB index and so on. The MIB information carried by the PBCH includes 6 bits in the SFN information field, 1 bit in the subcarrier spacing information field, 4 bits in the subcarrier offset information field in the SSB, and 8 bits in the PDCCH configuration information field in the SIB 1. The first communication device will further read the SIB1 message and other system messages to achieve synchronization with the base station.

After synchronization is achieved, resource allocation can be performed so that the first communication device can perform data transmission on the allocated resources.

Wherein, when the time that the first system occupies the first set of subcarriers to send data is different from the time that the second system occupies the second set of subcarriers to send data, in-band leakage will not be caused between the first system and the second system. , the first subcarrier set and the second subcarrier set may be continuous in the frequency domain. For example, in the in-vehicle communication scenario, it is assumed that the first system is a PEPS subsystem, and the second system is a subsystem that supports in-vehicle voice and time-frequency services. When the vehicle is not started, the PEPS subsystem occupies the first subcarrier set, the second system occupies the second set of sub-carriers; when the vehicle is in the starting state, the PEPS subsystem is in the stopped working state, in this case, the second set of sub-carriers and the first set of sub-carriers may be continuous in the frequency domain.

Wherein, when the first system and the second system are geographically close, or the difference between the transmission power of any subcarrier in the first subcarrier set and the transmission power of any subcarrier in the second subcarrier set When the value is less than the preset threshold, the far-near effect caused by the first system and the second system is weak, and the second control node can configure or preconfigure the first subcarrier set and the second subcarrier set to be continuous in the frequency domain .

For example, it is assumed that the first control node of the first system and the second control node of the second system are very close geographically, and the first control node in the first system occupies the first position in the frequency domain corresponding to the C-link symbol. The subcarrier set transmits data in the C link direction, and the second control node in the second system occupies other subcarrier sets in the frequency domain position corresponding to the C link symbol to transmit data in the C link direction. In this case, since the transmit powers on each subcarrier sent by the first communication device and the second control node are close to each other, the far-near effect is weak, so the first subcarrier set and the second subcarrier There may be no guard subcarriers left between sets.

For example, it is assumed that the first control node of the first system and the second control node of the second system are very close geographically, and the first communication device in the first system occupies the first sub-section of the frequency domain position corresponding to the T link symbol. The carrier set transmits data in the T link direction, and the second control node in the second system occupies other subcarrier sets in the frequency domain position corresponding to the T link symbol to transmit data in the T link direction. In this case, since the signal power of the first communication device in the first system received by the second control node and the first control node is close, the far-near effect is weak, so the first sub-carrier set and the second sub-carrier set are There may be no guard subcarriers left in between.

In this embodiment of the present application, the location information of the first subcarrier set and/or the location information of the second subcarrier set is acquired through the second control node, where the first subcarrier set is occupied by the first system for more than The set of subcarriers in the frame, the second set of subcarriers is the set of subcarriers in the superframe occupied by the second system, and the position information of the first set of subcarriers is determined by the control node, so that the first set of subcarriers can be realized.
