The distributed ultra-large-scale antenna system in the 6G network has the remarkable characteristics of more antennas, wider distribution geographic range and deeper intelligent synergistic effect. The distributed ultra-large-scale antenna system is formed by a large number of sites distributed at different geographic positions to form a distributed cooperation cluster. And interacting information such as scheduling and the like among the multiple sites in cooperation, and cooperatively finishing processes such as resource scheduling, data joint transmission and the like. By intelligent interaction and intelligent cooperation, on one hand, interference is effectively eliminated, and signal receiving quality is enhanced; on the other hand, coverage is effectively enhanced, and the user boundary sense is eliminated.
The working flow of the existing distributed system on the protocol is that after a terminal accesses a network, the quality of an adjacent cell or a TRP (transmission and reception point) is measured, and after a measurement result is reported, a proper TRP is selected for cooperative transmission. In an actual scenario, a more static method is adopted, and when deployed, a cooperative base station/RRU is selected, and is directly configured according to a cell and performs cooperative transmission.
In a high-capacity hot spot area, high-low frequency cooperative deployment can meet the capacity requirement of the hot spot area as far as possible on the basis of ensuring coverage. The site coverage of high frequency is small, but the capacity in a small range can be greatly improved, so that distributed deployment in a certain range is also a typical requirement and scene of high frequency deployment.

And then selecting a proper TRP for cooperative transmission based on the measurement result of the high frequency band.
In the prior art, a terminal needs to access a network first and then can perform cooperative transmission on a traffic channel in order to obtain distributed cooperative transmission. In the case of a high-frequency and low-frequency cooperative network, the process is more tedious, and the cooperative transmission can be started only after the low-frequency access and the high-frequency access are performed.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In the design of 4G LTE and 5G NR, a synchronization signal (PSS + SSS) transmitted by one base station or one TRP corresponds to only one cell ID on one frequency point (sync separator). In the 5G NR, due to the operation of introducing the beam, each synchronization broadcast signal block (SS/PBCH block, SSB) additionally carries an SSB index (index) which can be used to identify the beam.
In a distributed system, synchronization signals on a sync raster are divided into two types through protocol convention or master node configuration, wherein one type of synchronization signals are synchronization signals transmitted by a single station (uncooperative SSB), and the other type of synchronization signals transmitted in a cooperative mode (cooperative SSB).
As shown in fig. 1, in the transmission position of the uncooperative SSB, the SSB transmitted by each base station/TRP corresponds to the cell ID; there may be multiple base stations/TRPs transmitting SSBs at this location, and these SSBs are interfering signals with each other due to different cell IDs. At the transmission position of the cooperative SSB, the base station/TRP sends a synchronous signal according to the cooperative ID, and the base station/TRP which sends the SSB by using the same cooperative ID can be regarded as the SSB sent in an SFN way, so that the signal is enhanced; there may also be multiple different collaboration IDs sending SSBs at the same location, and there is also an interference relationship between them.
As shown in fig. 2, an embodiment of the present invention provides a method for sending a synchronization signal block, which is applied to a network device, and the method includes:
and step 21, sending the synchronous signal block according to the first type identification and/or the second type identification, wherein the first type identification and the second type identification are used for indicating the sending position of the synchronous signal block.
In this embodiment of the present invention, the synchronization signal block is transmitted according to the first class identifier and/or the second class identifier, where the first class identifier and the second class identifier are used to indicate a transmission position of the synchronization signal block. The cooperative transmission is started in the access stage, so that the time delay is reduced, the speed of the access flow is improved or the reliability is enhanced; realizing semi-dynamic flexible clustering through cooperation among beams; the terminal blind detection complexity is not increased, and the cooperative transmission in the access process is realized.
Here, the first type identifier and the second type identifier indicating the transmission position of the synchronization signal block may be configured to the terminal; or the protocol appointed position and the corresponding relation between the first type identification and the second type identification, and the network side directly sends the synchronous signal block according to the first type identification and/or the second type identification.
In an alternative embodiment of the present invention, the first type identifier is a location identifier of M1 uncooperative synchronization signal blocks in a transmission period of a synchronization signal block; the second type is the position identification of M2 cooperative synchronization signal blocks in the transmission period, where M1 and M2 are positive integers.
In an alternative embodiment of the present invention, the location identifiers of the M1 uncooperative synchronization signal blocks are represented by cell identifiers corresponding to the synchronization signal blocks, respectively; the location identities of the M2 cooperative synchronization signal blocks are represented by a virtual cell identity.
In an alternative embodiment of the present invention, the sequence numbers of the M1 uncooperative synchronization signal blocks are consecutive, and the sequence numbers of the M2 cooperative synchronization signal blocks are consecutive; the sequence number of the last of the M1 uncooperative synchronization signal blocks is consecutive to the sequence number of the first of the M2 cooperative synchronization signal blocks.
In an alternative embodiment of the present invention, step 12 may comprise:
the transmission receiving point TRP transmits the synchronous signal block at the transmission position of the synchronous signal block represented by the first type mark; and/or the presence of a gas in the gas,
the plurality of transmission reception points TRP transmit the synchronization signal blocks at the transmission positions of the synchronization signal blocks indicated by the second type identifiers.
As shown in fig. 3, in the above embodiment of the present invention, when sending the synchronization signal block, the synchronization signal sequence in the uncooperative synchronization signal block (the synchronization signal block corresponding to the above-mentioned first type identifier) corresponds to the cell ID, and the synchronization signal sequence in the cooperative synchronization signal block (the synchronization signal block corresponding to the above-mentioned second type identifier) corresponds to the cooperation ID and can be regarded as a virtual cell ID. The two are completely distinguished in sequence, so that the terminal can be ensured to distinguish different synchronous signal blocks for subsequent operation. The time positions of two kinds of synchronization signal blocks can be distinguished by protocol agreement or pre-configuration, so that the terminal uses the cell IDs in different ranges to perform blind search at different positions, the complexity of the terminal cannot be increased, and specifically: protocol convention or configuration, there are M sync signal block transmission positions in a period, where the first M1 sync signal blocks are positions of uncooperative sync signal blocks, and the last M2 sync signal blocks are positions of cooperative sync signal blocks. At the first M1 positions, the synchronization signal sequence is defined by the cell ID, and at the last M2 positions, the synchronization signal sequence is defined by the cooperation ID.
When a terminal searches a cell, the cell ID and the cooperation ID are used for respectively detecting the position of an uncooperative synchronous signal block and the position of a cooperative synchronous signal block, the cooperative synchronous signal block transmitted by the SFN can improve the receiving energy, and when the terminal judges an access criterion, the cooperative synchronous signal block can be selected for access if the received RSRP of the cooperative synchronous signal block is higher than that of the uncooperative synchronous signal block within a certain range. Therefore, the terminal is accessed into the cooperative synchronous signal block by restricting the terminal access criteria on different synchronous signal blocks, thereby realizing the cooperative transmission in the access stage.
After the terminal completes the measurement of the synchronization signal block, it needs to acquire the random access resource information corresponding to the synchronization signal block. In the system message, the period of occurrence and the time domain position of the PRACH resource corresponding to the current synchronization signal block may be configured, and the PRACH resource position to which the PRACH resource belongs is related to the synchronization signal block position. This may enable a cooperative reception of random access resources.
The embodiment of the invention also provides a method for receiving the synchronous signal block, which is applied to a terminal and comprises the following steps:
and detecting the synchronous signal blocks at different positions according to the first type identification and/or the second type identification, wherein the first type identification and the second type identification are used for representing the sending positions of the synchronous signal blocks.

and when the receiving quality of the synchronization signal block received at the transmitting position represented by the second type identifier is higher than the receiving quality of the synchronization signal block received at the transmitting position represented by the first type identifier by a preset range, selecting the synchronization signal block received at the transmitting position represented by the second type identifier for cell access.
Optionally, before selecting the synchronization signal block received at the sending position represented by the second type identifier for cell access, the method further includes:
and acquiring the random access resource information corresponding to the synchronous signal block received at the transmitting position represented by the second type identification.

the sequence number of the last of the M1 uncooperative synchronization signal blocks is consecutive to the sequence number of the first of the M2 cooperative synchronization signal blocks.
In this embodiment of the present invention, as shown in fig. 3, when the terminal performs cell search, the cell ID and the cooperation ID are used to perform detection at the uncooperative synchronization signal block position and the cooperative synchronization signal block position, so as to consider that the cooperative synchronization signal block of SFN transmission will increase the received energy, and when the terminal performs the access criterion determination, it may be considered that the cooperative synchronization signal block is selected for access only if the received RSRP of the cooperative synchronization signal block is higher than that of the uncooperative synchronization signal block by a certain range. The effect is as follows: the terminal access to the cooperative synchronization signal block is realized by constraining the terminal access criteria on different synchronization signal blocks, thereby realizing the cooperative transmission in the access stage.
After the terminal completes the measurement of the synchronization signal block, it needs to acquire the random access resource information corresponding to the synchronization signal block. In the system message, the period of occurrence and the time domain position of the PRACH resource corresponding to the current synchronization signal block may be configured, and the PRACH resource position to which the PRACH resource belongs is related to the synchronization signal block position. The effect is as follows: coordinated reception of random access resources may be achieved.
In the above embodiments of the present invention, the synchronization signal sequence corresponds to a cell ID (first type ID) or a cooperation ID (second type ID), or besides the cell ID, the cooperation ID may also define the synchronization signal sequence; it may be considered that a cooperative SSB (synchronization signal of the second type) is selected for access only if its received RSRP is higher than that of a non-cooperative SSB (synchronization signal of the first type) by a certain range. Through protocol agreement or configuration, there are M SSBs transmitting positions in a period, where M1 SSBs are positions of uncooperative SSBs, and M2 SSBs are positions of cooperative SSBs. At M1 positions, the synchronization signal sequence is defined by the cell ID (first type ID), and at the other M2 positions, the synchronization signal sequence is defined by the cooperation ID (second type ID). And the terminal is accessed to the cooperative SSB, so that cooperative transmission in an access phase is realized.
