Description

Method and equipment for sending and receiving synchronous priority information
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for sending and receiving synchronization priority information.
Background
In Rel-14/Rel-15LTE (Long Term Evolution; long Term Evolution) V2X (Vehicle to Everything) technology, synchronization priority information of a direct link sip is carried by a Primary Sip Synchronization Signal (PSSS) and a SSSS (Secondary sip Synchronization Signal).
As shown in fig. 1, a schematic diagram of a R15V2X Sidelink synchronization subframe structure in the prior art is shown, where an abscissa represents a time domain, each column represents one OFDM (Orthogonal Frequency Division Multiplexing) symbol, and an LTE V2X Sidelink synchronization signal occupies 14 symbols in the time domain. The ordinate represents the frequency domain, and the LTE V2X Sidelink synchronization signal occupies 6 RBs (Resource Block ) in the frequency domain. The PSSS and the SSSS each occupy 2 symbols, and these Synchronization signals carry Synchronization priority information in the form of SLSS-ID (Sidelink Synchronization Signal-Identity). The receiving device detects the acquired SLSS-ID information through the PSSS and SSSS sequences, and different SLSS-ID values correspond to different synchronization priority information, for example, when the detected SLSS-ID =0, it indicates that the transmitting device is synchronized with a GNSS (Global Navigation Satellite System).
It can be known that the synchronization priority information can be acquired only when the synchronization signal is received. However, the synchronization signal of the Sidelink is sparse and has a long period. In addition, in order to acquire the synchronization priority information, SLSS-ID information needs to be detected to acquire the synchronization priority information, and a manner of detecting the SLSS-ID brings higher system processing complexity, so that a manner of detecting the SLSS-ID to acquire the synchronization priority information causes synchronization delay, and the complexity of synchronization by using a synchronization signal is high.
In summary, in the prior art, in the synchronization process, the SLSS-ID is detected to obtain the synchronization priority information, which results in synchronization delay and synchronization complexity.

Because the indication information used for determining the synchronization priority information is carried in the reference signal for transmission, and the mode for transmitting the synchronization priority information is simple, the receiving equipment determines the synchronization priority information according to the indication information used for determining the synchronization priority information, thereby reducing the synchronization time delay and the synchronization complexity of the receiving equipment, improving the throughput rate of the Sidelink communication and reducing the Sidelink communication time delay.
In the embodiment of the invention, the reference signal comprises DMRS and/or AGC-RS and/or PT-RS. Therefore, the sending equipment carries the indication information for determining the synchronization priority information in the DMRS, and/or carries the indication information for determining the synchronization priority information in the AGC-RS, and/or carries the indication information for determining the synchronization priority information in the PT-RS and sends the indication information to the receiving equipment. Fig. 3 is a schematic diagram illustrating the transmission of synchronization priority information using a reference signal according to an embodiment of the present invention.
In the embodiment of the present invention, the indication information carried in the reference signal for determining the synchronization priority information includes: synchronizing the priority information; or an index value corresponding to the synchronization priority information.

Therefore, the sending device directly carries the synchronization priority information in the reference signal and sends the reference signal to the receiving device, and after the receiving device receives the reference signal, the synchronization priority information in the reference signal is obtained. And further, the receiving equipment determines the synchronization state of the sending equipment for sending the reference signal and the GNSS or the base station according to the acquired synchronization priority information. Because the synchronization priority information is directly acquired and the period of the reference signal is short, the synchronization time delay and the synchronization complexity of the receiving equipment are reduced. Or
The sending equipment carries the index value corresponding to the synchronization priority information in the reference signal and sends the reference signal to the receiving equipment, after the receiving equipment receives the reference signal, the index value corresponding to the synchronization priority information in the reference signal is obtained, and the synchronization priority information is determined according to the index value corresponding to the synchronization priority information. And further, the receiving equipment determines the synchronization state of the sending equipment for sending the reference signal and the GNSS or the base station according to the determined synchronization priority information.
The following description will be made in detail with respect to carrying index values corresponding to different synchronization priority information in different reference signals.
1. The reference signal is DMRS.
The first embodiment is as follows: the DMRS sequence index value is carried in a reference signal.
In an embodiment of the present invention, the transmitting device indicates whether to directly synchronize with the GNSS using a different DMRS sequence.
The method includes the steps that a sending device determines synchronization priority information needing to be sent, determines a DMRS sequence index value corresponding to the synchronization priority information needing to be sent according to the corresponding relation between the synchronization priority information and the DMRS sequence index value, carries the synchronization priority information needing to be sent in a reference signal DMRS in a mode of the DMRS sequence index value, and sends the reference signal, and as shown in FIG. 4, a schematic diagram of transmitting the synchronization priority information in a mode of carrying indication information used for determining the synchronization priority information by using the DMRS is provided for the embodiment of the invention;
after receiving the reference signal sent by the sending equipment, the receiving equipment determines synchronization priority information through a DMRS sequence index value used by a blind detection reference signal DMRS, and determines whether to be directly synchronized with the GNSS according to the synchronization priority information.
The synchronization priority information has 1 bit, which corresponds to the following two cases, as shown in table 1:
DMRS sequence index values Synchronizing priority information bit values Synchronizing priority information
Sequence A
1 Direct synchronization with GNSS
Sequence B
0 Not directly synchronized with GNSS
TABLE 1
When the synchronization priority information is determined according to the index value corresponding to the synchronization priority information, the receiving equipment determines the synchronization priority information corresponding to the DMRS sequence index value carried in the received reference signal according to the corresponding relation between the sequence index value corresponding to the synchronization priority information and the synchronization priority.
For example, the DMRS sequence index value carried in the received reference signal is sequence a, and the corresponding synchronization priority information bit is determined to be 1, and at this time, it is determined that the transmitting device that transmits the reference signal is directly synchronized with the GNSS;
and the DMRS sequence index value carried in the received reference signal is a sequence B, the corresponding synchronization priority information bit is determined to be 0, and at the moment, the transmitting equipment for transmitting the reference signal is determined not to be directly synchronized with the GNSS.
In implementation, the number of bits occupied by the synchronization priority information is small, the complexity of blind detection of the DMRS sequences is reduced, the detection success rate of the synchronization priority information is increased, and meanwhile, the index value of the DMRS sequences is used for indicating whether the transmitting equipment for transmitting the reference signals is directly synchronous with the GNSS or not.
The second embodiment: the DMRS sequence group index value is carried in a reference signal.
In an embodiment of the present invention, the transmitting device uses different sets of DMRS sequences to indicate whether to synchronize directly with the GNSS or the base station.
The method comprises the steps that a sending device determines synchronization priority information needing to be sent, determines a DMRS (demodulation reference signal) sequence group index value corresponding to the synchronization priority information needing to be sent according to the corresponding relation between the synchronization priority information and the DMRS sequence group index value, carries the synchronization priority information needing to be sent in a reference signal DMRS in a mode of the DMRS sequence group index value, and sends the reference signal;
after receiving the reference signal sent by the sending equipment, the receiving equipment determines synchronization priority information by blind detecting a DMRS sequence group index value used by a reference signal DMRS, and determines whether to be directly synchronized with a GNSS or a base station according to the synchronization priority information.
The synchronization priority information has 2 bits, corresponding to the following four cases, as shown in table 2:
DMRS sequence group index value Synchronizing priority information bit values Synchronizing priority information
Sequence group A 11 Direct synchronization with GNSS
Sequence group B 10 Direct synchronization with base station
Sequence group C 01 Indirect and GNSS synchronization
Sequence group D 00 Indirectly synchronizing with base station
TABLE 2
When the synchronization priority information is determined according to the index value corresponding to the synchronization priority information, the receiving equipment determines the synchronization priority information corresponding to the index value of the DMRS sequence group carried in the received reference signal according to the corresponding relationship between the sequence group index value and the synchronization priority.
For example, the DMRS sequence group index value carried in the received reference signal is sequence a, and the synchronization priority information bit is determined to be 11, at this time, it is determined that the transmitting device that transmits the reference signal is directly synchronized with the GNSS;
the index value of a DMRS sequence group carried in the received reference signal is a sequence B, the synchronization priority information bit is determined to be 10, and at the moment, the sending equipment for sending the reference signal is determined to be directly synchronous with the base station;
the index value of a DMRS sequence group carried in the received reference signal is a sequence C, the synchronization priority information bit is determined to be 01, and at the moment, the sending equipment for sending the reference signal is determined to be indirectly synchronous with the GNSS;
and the index value of a DMRS sequence group carried in the received reference signal is a sequence D, the synchronization priority information bit is determined to be 00, and at the moment, the transmitting equipment for transmitting the reference signal is determined to be indirectly synchronized with the base station.
In implementation, the sending device sending the reference signal is indicated to be directly or indirectly synchronized with the GNSS or the base station through the DMRS sequence group index value, and the amount of synchronization priority information provided is large.
Example three: the DMRS port index value is carried in a reference signal.
In an embodiment of the invention, the transmitting device uses different DMRS ports to indicate whether to synchronize directly with the GNSS.
The method comprises the steps that a sending device determines synchronization priority information needing to be sent, determines a DMRS port index value corresponding to the synchronization priority information needing to be sent according to the corresponding relation between the synchronization priority information and the DMRS port index value, carries the synchronization priority information needing to be sent in a reference signal DMRS in a mode of the DMRS port index value, and sends the reference signal;
after receiving the reference signal sent by the sending equipment, the receiving equipment determines synchronization priority information through a DMRS port index value used by a blind detection reference signal DMRS, and determines whether to be directly synchronized with the GNSS according to the synchronization priority information.
The synchronization priority information has 1 bit, which corresponds to the following two cases, as shown in table 3:
DMRS port index values Synchronizing priority information bit values Synchronizing priority information
Port A
1 Direct and GNSS synchronization
Port B
0 Not directly synchronized with GNSS
TABLE 3
And when the synchronization priority information is determined according to the index value corresponding to the synchronization priority information, the receiving equipment determines the synchronization priority information corresponding to the DMRS port index value carried in the received reference signal according to the corresponding relation between the port index value and the synchronization priority.
For example, the DMRS port index value carried in the received reference signal is port a, and the synchronization priority information bit is determined to be 1, at this time, it is determined that the transmitting device that transmits the reference signal is directly synchronized with the GNSS;
and the DMRS port index value carried in the received reference signal is port B, the synchronization priority information bit is determined to be 0, and at the moment, the transmitting equipment for transmitting the reference signal is determined not to be directly synchronized with the GNSS.
In implementation, the number of bits occupied by the synchronization priority information is small, the complexity of blind detection of the DMRS port is reduced, the detection success rate of the synchronization priority information is increased, and meanwhile, the index value of the DMRS port sequence is used for indicating whether the transmitting equipment for transmitting the reference signal is directly synchronous with the GNSS or not.
Example four: the DMRS port group index value is carried in a reference signal.
In the embodiments of the present invention, the transmitting device uses different DMRS port groups to indicate whether to directly synchronize with the GNSS or the base station.
The method comprises the steps that a sending device determines synchronization priority information needing to be sent, determines a DMRS (demodulation reference signal) port group index value corresponding to the synchronization priority information needing to be sent according to the corresponding relation between the synchronization priority information and the DMRS port group index value, carries the synchronization priority information needing to be sent in a reference signal DMRS in a mode of the DMRS port group index value, and sends the reference signal;
after receiving the reference signal sent by the sending equipment, the receiving equipment determines synchronization priority information through a DMRS port group index value used by a blind detection reference signal DMRS, and determines whether to be directly synchronized with a GNSS or a base station according to the synchronization priority information.
The synchronization priority information has 2 bits, corresponding to the following four cases, as shown in table 4:
DMRS port group index values Synchronizing priority information bit values Synchronizing priority information
Port group A 11 Direct and GNSS synchronization
Port group B 10 Direct synchronization with base station
Port group C 01 Indirect and GNSS synchronization
Port group D 00 Indirectly synchronizing with base station
TABLE 4
When the synchronization priority information is determined according to the index value corresponding to the synchronization priority information, the receiving equipment determines the synchronization priority information corresponding to the DMRS port group index value carried in the received reference signal according to the corresponding relation between the reference signal port group index value and the synchronization priority.
