Description

Method for sending synchronization signal block and network equipment
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method and network equipment for sending a synchronous signal block.
Background
Fifth generation communication technology (5)thgeneration, 5G) is representative of a new generation of information technology, introducing a new architecture and various innovative key technologies.5G aims to serve three major scene categories, namely enhanced mobile broadband (eMBB), Ultra-Reliable and L ow L activity Communications, UR LL C, and massive Machine Type Communication (mtc), where eMBB is the most important application scenario for 5G initial business, namely, providing higher system capacity, higher data throughput, more seamless wireless connectivity, better user experience, etc.
In a New Radio (NR) 5G, a terminal (UE) acquires time and frequency Synchronization with a serving cell based on a Synchronization Signal Block (SSB) transmitted by a network device.
Referring to fig. 1, a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH) together form an SSB (SS/PBCH block). As shown in fig. 1, 1 SSB is composed of 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols, which are numbered in an increasing order from 0 to 3 within the SSB, and the PSS, SSS, and PBCH occupy different symbols. In the frequency domain, 1 SSB consists of 240 consecutive subcarriers, which are numbered in increasing order from 0 to 239 within the SSB.
In the fourth generation communication technology (4th generation, 4G), network devices use Cell Reference Signals (CRS) as power references according to Resource Element (RE) level transmission power of all downlink channels, and the implementation of 5G network devices also follows the 4G approach, while CRS has been cancelled in the 5G protocol, and the implementation of 5G network devices configures transmission power of SSBs with Energy Per Resource Element (EPRE) of PBCH as a Reference. Since the UE receives the SSB only after synchronization, the coverage of the synchronization signal in the prior art is weaker than that of the PBCH. Even if the UE receives the PBCH, it may not be able to read the broadcast message due to the failure to synchronize. The "zero" portion indicates that the transmission power is 0 when the network device transmits the SSB, which results in the transmission power not being stable when the network device transmits the SSB. The fast change of the transmission power has higher requirements on the stability of the radio frequency module of the network equipment. In the process, the transmission power of the PSS and the SSS is lower than that of the PBCH, which increases the difficulty of detecting the PSS and the SSS by the terminal.

As shown in fig. 2, the wireless communication system may include: a network device 21 and a user device 22. In practical applications, the connections between the above devices may be wireless connections, and fig. 2 is illustrated with solid lines for convenience and intuition of the connection relationships between the devices.

Referring to fig. 3, an embodiment of the present invention provides a method for sending a synchronization signal block, where an execution main body of the method is a network device, and the method includes the following specific steps:
step 301: determining second transmitting power of the rest OFDM symbols in the SSB according to the first transmitting power of the target OFDM symbol in the SSB;
in the embodiment of the invention, one OFDM symbol in the SSB is taken as a target OFDM symbol, and the first transmission power of the target OFDM symbol is taken as a reference to determine the second transmission power of the rest OFDM symbols in the SSB.
Optionally, the first transmit power is determined as the second transmit power, so that the transmit power of each OFDM symbol in the SSB is uniform, and the transmit power of the entire SSB is stable during transmission.
Further, as can be seen from the structure of the SSB in fig. 1, the transmission power of the OFDM symbol 1 and the OFDM symbol 3 is the same, and the OFDM symbol 1 or the OFDM symbol 3 is determined as the target OFDM symbol. Therefore, the transmitting power of the PSS and the SSS is improved while the stability of the transmitting power of the whole SSB is ensured, a Physical Downlink Shared Channel (PDSCH) is not occupied, and the downlink transmission rate is not influenced. In addition, PSS and SSS transmission power is improved, the condition that only PBCH is received but PSS and SSS are not received when a terminal receives SSB is avoided, and the terminal can read broadcast messages.
Step 302: determining target transmitting power according to the first transmitting power and the second transmitting power;
in the embodiment of the invention, the target transmission power of the whole SSB can be determined according to the first transmission power of the target OFDM symbol and the second transmission power of the target OFDM symbol and the OFDM symbol.
Specifically, the target transmission power is calculated by the following formula:
Y0＝10lg(x′·N1)；
Y1＝10lg(x·N2)；
Y2＝10lg(x·N3+x″·N1)；
Y3＝10lg(x·N2)；
Yt＝Y0+Y1+Y2+Y3；

wherein, Y0Is the transmission power of OFDM symbol 0, Y1Is the transmission power of OFDM symbol 1, Y2Is the transmission power of OFDM symbol 2, Y3Is the transmission power of OFDM symbol 3, YtTransmitting power for the target; n is a radical of1Is the number of resource elements RE of the primary synchronization signal PSS corresponding to the OFDM symbol 0, N2Number of REs of PBCH corresponding to OFDM symbol 1 or 3, N3Number of REs of PBCH corresponding to OFDM symbol 2, N2-N3For secondary synchronization corresponding to OFDM symbol 2The number of REs of the signal SSS; x is the preset transmit power for each RE, x' is the transmit power of the REs of the PSS corresponding to OFDM symbol 0, and x "is the transmit power of the REs of the SSS corresponding to OFDM symbol 2. The preset transmit power for each RE may be derived from the SSB downlink transmit power given by the parameter SS-PBCH-BlockPower provided by the higher layer.
Step 303: the SSB is transmitted with the target transmit power.
In the embodiment of the invention, the network equipment determines the second transmitting power of the rest OFDM symbols in the SSB through the first transmitting power of the target OFDM symbols, determines the target transmitting power according to the first transmitting power and the second transmitting power, and transmits the SSB through the target transmitting power, so that the transmitting power of the SSB is stable, and the difficulty of detecting the synchronous signal by the terminal is reduced.
Combining fig. 1 and the above formula in step 302, when transmitting OFDM symbol 0, the transmit power equivalent to 240 REs is aggregated on 127 REs transmitting PSS, where the transmit power of each RE of PSS is
Figure BDA0001937126230000071
Substituting the formula to obtain:
Figure BDA0001937126230000072
similarly, when OFDM symbol 2 is transmitted, transmit power equivalent to 144 REs is aggregated over 127 REs transmitting SSS, where transmit power per RE of SSS
Figure BDA0001937126230000073
In addition, PBCH is sent by 96 REs, and the PBCH is obtained by substituting the following formula:
Y2＝10lg(x·96+x″·127)＝10lgx+10lg(144+96)
＝10lgx+10lg240；
when transmitting OFDM symbols 1 and 3, the PBCH is transmitted by 240 REs, and the PBCH is obtained by substituting the following formula:
Y1＝10lg(x·240)＝10lgx+10lg240；
Y3＝10lg(x·240)＝10lgx+10lg240；
the target transmit power of the entire SSB is calculated from OFDM symbols 0, 1, 2, 3:
Yt＝Y0+Y1+Y2+Y3＝40lgx+40lg240；
compared with the existing method for transmitting SSB, the transmission power of each RE in the existing method is constant as x0Then, the formula is substituted to obtain:
when OFDM symbol 0 is transmitted, Y0′＝10lg(x·127)＝10lgx+10lg 127；
When transmitting OFDM symbol 1, Y1′＝10lg(x·240)＝10lgx+10lg240；
When transmitting OFDM symbol 2, Y2′＝10lg(x·223)＝10lgx+10lg223；
When transmitting OFDM symbol 3, Y3′＝10lg(x·240)＝10lgx+10lg240；
Total power of SSB: y't＝Y′0+Y′1+Y′2+Y′3
＝40lgx+10(lg 127+lg240+lg223+lg240)；
ΔY＝Yt-Y′t＝10(2·lg240-lg127-lg223)＝3.08dB；
Therefore, by adopting the method of the embodiment of the invention, the transmitting power is improved while the SSB transmitting power is ensured to be stable, so that the transmission distance is increased, and the network coverage area is enlarged.
