Description

Method and device for sending and receiving synchronization signal burst set, storage medium, base station and user equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for sending and receiving a synchronization signal burst set, a storage medium, a base station, and a user equipment.
Background
With the development of wireless communication technology, the third Generation Partnership Project (3 GPP) introduced New Radio (NR) technology. In NR, a set of Synchronization Signal Bursts (SSB) contains at most L Synchronization Signal Blocks (SSB), where L is associated with a frequency range. Specifically, in the frequency range below 3 gigahertz (GHz), L is 4; l is 8 in the frequency range of 3GHz to 6 GHz; in the frequency range of 6GHz to 52.6GHz, L is 64. Therefore, a bit sequence for representing L Synchronization signal block time indices (SSB TI) requires at least 6 bits. This bit sequence is denoted b5b4b3b2b1b 0. The 3 bits in b5b4b3b2b1b0 are carried by a Demodulation reference signal (DMRS) of a broadcast channel (PBCH). It should be noted that when there is a problem in using DMRS of PBCH to carry 3 bits of information, the above design may fall back to 2 bits. That is, 2 bits in b5b4b3b2b1b0 would be carried with DMRS of PBCH.
In the prior art, when 3 bits in b5b4b3b2b1b0 are carried by using DMRS of PBCH, after DMRS detection of PBCH is completed, information of 3 bits in SSB TI may be obtained. For the frequency range below 6GHz, after completing DMRS detection of PBCH, the information of SSB TI can be fully obtained. The boundaries of the burst sets of synchronization signals can then be determined. When 2 bits in b5b4b3b2b1b0 are carried by DMRS of PBCH, after completing DMRS detection of PBCH, information of 2 bits in SSB TI may be obtained. For the frequency range below 3GHz, after completing DMRS detection of PBCH, the information of SSB TI can be fully obtained. The boundaries of the burst sets of synchronization signals can then be determined. For the frequency range from 3GHz to 6GHz, after completing the DMRS detection of PBCH, 1 bit of information is not yet obtained in the SSB TI. However, according to the design of the 3GPP NR regarding the synchronization signal block composition of 15kHz and 30kHz, the boundary of the synchronization signal burst set can be determined.
However, in a scenario where the subcarrier spacing is 120kHz and the period of the synchronization signal burst set is 5ms, no matter whether 3 or 2 bits of the SSB TI are carried by the DMRS of the PBCH, the boundary of the synchronization signal burst set cannot be determined by DMRS detection of the PBCH. In such a scenario, for a plurality of SSBs, it cannot be determined in advance whether they belong to the same synchronization signal burst set, and further cannot be determined in advance whether they belong to the same PBCH TTI. This uncertainty can lead to a large number of blind detection combinations during PBCH soft combining, thereby resulting in an increased complexity of the terminal for demodulating PBCH.

Detailed Description
As described in the background art, in the prior art, in a scenario where the subcarrier interval is 120kHz and the period of the synchronization signal burst set is 5ms, no matter 3 or 2 bits of the SSB TI are carried by the DMRS of the PBCH, the boundary of the synchronization signal burst set cannot be determined by DMRS detection of the PBCH. In such a scenario, for a plurality of SSBs, it cannot be determined in advance whether they belong to the same synchronization signal burst set, and further cannot be determined in advance whether they belong to the same PBCH TTI. This uncertainty can lead to a large number of blind detection combinations during PBCH soft combining, thereby resulting in an increased complexity of the terminal for demodulating PBCH.
The technical scheme of the invention groups the time indexes of all the synchronous signal blocks in the synchronous signal burst set, and then sends the group number of the index group as the bit to be sent to the user equipment, so that the user equipment can determine the boundary of the synchronous signal burst set according to the arrangement sequence of the group numbers so as to be used for other subsequent operations.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a method for transmitting a synchronization signal burst set according to an embodiment of the present invention.
The method for transmitting the synchronization signal burst set shown in fig. 1 may be used on the base station side, and may include the following steps:
step S101: determining the number of bits to be transmitted;
step S102: arranging the time indexes of all synchronous signal blocks in each synchronous signal burst set in sequence, and uniformly grouping according to the number of bits to be sent to obtain a plurality of sequentially arranged index groups, wherein the time indexes in each index group are continuous, and the plurality of sequentially arranged index groups have sequentially arranged group numbers;
step S103: taking binary numbers corresponding to the group number to which the time index of each synchronous signal block belongs as bits to be sent;
step S104: and carrying the bit to be sent in a corresponding synchronous signal block, and sending the bit to be sent to user equipment, so that the user equipment can determine the boundary of the synchronous signal burst set to which the received synchronous signal block belongs according to the bit to be sent.
In a specific implementation, in step S101, the number of bits to be transmitted is determined. Specifically, the number of bits to be transmitted may be preset; or may be selected from a predetermined plurality of values. Since the bits represent binary numbers, the maximum decimal number that the bits to be transmitted can represent can be determined by the number of bits to be transmitted. For example, when the number of bits to be transmitted is 2, the maximum decimal number that can be represented by the bits to be transmitted is 4; when the number of bits to be transmitted is 3, the maximum decimal number that can be represented by the bits to be transmitted is 8.
In particular implementations, each set of Synchronization signal bursts may include a plurality of Synchronization Signal Blocks (SSBs), each having a Time Index (TI). In step S102, the time indexes of all the synchronization signal blocks in each synchronization signal burst set are arranged in sequence, and are uniformly grouped according to the number of bits to be transmitted. Specifically, the number of time indexes in a plurality of index groups obtained by grouping is consistent; the number of index groups is related to the number of bits to be transmitted. In other words, the number of index groups may be less than or equal to the maximum decimal number that the bits to be transmitted can represent.
For example, when the number of bits to be transmitted is 2, the number of index groups may be less than or equal to 4; when the number of bits to be transmitted is 3, the number of index groups may be 8 or less.
In step S103, a binary number corresponding to the group number to which the time index of each synchronization signal block belongs is used as a bit to be transmitted. Further, in step S104, the bits to be sent are carried in the corresponding synchronization signal block and sent to the user equipment. After receiving the synchronization signal block, the user equipment may determine a group number corresponding to the synchronization signal block through a bit to be sent.
In this embodiment, the base station may send bits to be sent corresponding to the time indexes of all the synchronization signal blocks in the synchronization signal burst set to the user equipment; or selecting the bit to be sent corresponding to the time index of the partial synchronization signal block in the synchronization signal burst set and sending the bit to be sent to the user equipment.
Specifically, since the plurality of index groups in each synchronization signal burst set have sequentially arranged group numbers, after the user equipment determines the group numbers by the bits to be transmitted, the user equipment can determine whether each synchronization signal block belongs to the same synchronization signal burst set according to the size of each group number, and further can determine the boundary of the synchronization signal burst set.
It can be understood that the boundary of the synchronization signal burst set may refer to a start time-frequency position or an end time-frequency position of the synchronization signal burst set; or a range of start or end time-frequency positions of the set of synchronization signal bursts.
The embodiment of the invention groups the time indexes of all the synchronous signal blocks in the synchronous signal burst set, and then sends the group number of the index group as the bit to be sent to the user equipment, so that the user equipment can determine the boundary of the synchronous signal burst set according to the arrangement sequence of the group numbers so as to be used for other subsequent operations.
In a specific application scenario, by determining the boundary of the burst set of synchronization signals, a relatively precise alignment operation can be performed without demodulating PBCH, so as to meet the diversified requirements of users.
Preferably, the transmission period of the synchronization signal burst set is 5 milliseconds, and the subcarrier interval of the synchronization signal burst set is 120 KHz.
Under the scene that the sending period of the synchronous signal burst set is 5 milliseconds and the subcarrier interval of the synchronous signal burst set is 120KHz, the prior art cannot determine the boundary of the synchronous signal burst set. By using the method for sending the synchronization signal burst set of the present embodiment, the boundary of the synchronization signal burst set can be determined.
When the transmission cycle of the synchronization signal burst set is another value and/or the subcarrier spacing of the synchronization signal burst set is another value, for example, the transmission cycle of the synchronization signal burst set is 20ms, 40ms, or 80ms, and the subcarrier spacing is 240KHz, 15KHz, or 30KHz, the transmission method of the synchronization signal burst set according to the embodiment of the present invention may be adopted.
Preferably, the number of bits to be transmitted is 2, and the number of index groups is 4, or the number of bits to be transmitted is 3 and the number of index groups is 8.
Preferably, step S103 may include the steps of: and selecting a binary high-digit number of the time index of each synchronous signal block to serve as a group number to which the time index of the synchronous signal block belongs, wherein the digit number of the high-digit number is consistent with the digit number of the bit to be transmitted.
In this embodiment, since the binary high-order digits of the time indexes of all the synchronization signal blocks in each synchronization signal burst set are also arranged sequentially, the binary high-order digit of the time index of each synchronization signal block can be selected as the group number to which the time index of the synchronization signal block belongs.
In an embodiment of the present invention, the number of bits to be transmitted is 3; the number of SSBs in the synchronization signal burst set is 64, and the number of actually transmitted SSBs is 64. SSB TI may be represented by Binary-Coded Decimal (also called BCD code) with high bits on the left.
The SSBs TI within a set of synchronization signal bursts are arranged in order, e.g., 1,2,3, … …, 64; or 0,1,2, … …, 63. The entire SSB TI is divided into 8 groups, each consisting of 8 consecutive SSB TI. Representing SSB TI as a 6-bit binary number b5b4b3b2b1b0. Such as 000000,000001,000010, …, 111111.

The SSBs TI within a set of synchronization signal bursts are arranged in order, e.g., 1,2,3, … …, 64; or 0,1,2, … …, 63. The entire SSB TI is divided into 4 groups, each consisting of 16 consecutive SSB TI. Representing SSB TI as a 6-bit binary number b5b4b3b2b1b0. Such as 000000,000001,000010, …, 111111.

In another variation of the present invention, the number of bits to be transmitted is 3; the number of SSBs in the synchronization signal burst set is 64, and the number of actually transmitted SSBs is 64. The SSB TI may be represented by Binary-Coded Decimal (also called BCD code) with high digits on the right.
The SSBs TI within a set of synchronization signal bursts are arranged in order, e.g., 1,2,3, … …, 64; or 0,1,2, … …, 63. The entire SSB TI is divided into 8 groups, each consisting of 8 consecutive SSB TI. Representing SSB TI as a 6-bit binary number b5b4b3b2b1b0. Such as 000000,000001,000010, …, 111111.

In another variation of the present invention, the number of bits to be transmitted is 2; the number of SSBs in the synchronization signal burst set is 64, and the number of actually transmitted SSBs is 64. SSB TI may be represented in BCD code with high order bits to the right.
The SSBs TI within a set of synchronization signal bursts are arranged in order, e.g., 1,2,3, … …, 64; or 0,1,2, … …, 63. The entire SSB TI is divided into 4 groups, each consisting of 16 consecutive SSB TI. Representing SSB TI as a 6-bit binary number b5b4b3b2b1b0. Such as 000000,000001,000010, …, 111111. Selecting6-bit binary representation b of SSB TI5b4b3b2b1b0High order bits b corresponding to the group number1b0As bits to be transmitted.
Preferably, step S102 may include the steps of: and arranging the time indexes of all the synchronous signal blocks in each synchronous signal burst set in a time ascending mode, and uniformly grouping to obtain a plurality of ascending index groups, wherein the ascending index groups have ascending group numbers.
In this embodiment, the time indexes of all the sync signal blocks in the sync signal burst set are arranged in an ascending time order, and thus the plurality of index groups have group numbers arranged in an ascending order. That is, each set of synchronization signal bursts has the same group number in ascending order.
Further, the ue determines, according to the bits to be transmitted, a group number of an index group to which a time index of a received synchronization signal block belongs, and if the group number of the index group to which the time index of the synchronization signal block with earlier timing belongs is greater than the group number of the index group to which the time index of the synchronization signal block with later timing belongs, the synchronization signal block with earlier timing and the synchronization signal block with later timing belong to different synchronization signal burst sets, and a boundary of the different synchronization signal burst sets is located between the synchronization signal block with earlier timing and the synchronization signal block with later timing.
In this embodiment, if the group numbers of two adjacent synchronization signal blocks are in ascending order in the ascending direction of the time index, the two adjacent synchronization signal blocks belong to the same synchronization signal burst set; if the group numbers of two adjacent synchronization signal blocks are in descending order in the direction of ascending time index, the two adjacent synchronization signal blocks belong to two adjacent synchronization signal burst sets, and the boundary of the two adjacent synchronization signal burst sets can be determined to be located between the two adjacent synchronization signal blocks.
