Method and equipment for sending synchronization signal

Technical Field

Background

In the fifth generation communication NR, a communication system introduces a high frequency band, and in order to combat path loss at high frequencies, a beamforming technique is introduced in the fifth generation communication NR. In the fifth generation communication NR, all links of communication will be based on beams, and synchronization signals and broadcast signals are no exception.

In this context, the time resources in the fifth generation communication NR are newly designed, and the minimum time unit in the designed time resources may correspond to the scanned beam pair one to one. The synchronization signal in the fifth generation communication NR is carried on the minimum time unit, and the network side apparatus repeats the synchronization signal on the beam scanned in rounds, so that the terminal side apparatus searches for a cell.

In the protocol agreement between the network side device and the terminal side device, only the maximum value of the minimum time unit number included in one preset period is agreed.

However, there is a case where the minimum time unit configured by the network-side device for carrying the synchronization signal is different based on the problem of the capability of the network-side device. However, based on the protocol convention between the network side device and the terminal side device at present, the terminal side device only knows the maximum value including the minimum time unit number in one preset period, and the number and the position of the minimum time unit configured for carrying the synchronization signal for the network side device cannot be known. In the case that the terminal side device does not know the number and position of the minimum time units configured by the network side device for carrying the synchronization signals, there is a problem that radio time resources are wasted.

The present invention will be described with reference to examples.

Example one

This example is a summary of the methods described herein. FIG. 8 is a flow chart illustrating a method according to an embodiment of the present disclosure.

As shown in fig. 8, a method for transmitting a synchronization signal includes:

and S40, the network side device generates a synchronization signal, wherein the synchronization signal is used for indicating the position information of the configured time resource for transmitting the synchronization signal in the preset time resource for transmitting the synchronization signal.

In S40, the time resource for transmitting the synchronization signal that is preset is usually sufficient, and in the actual communication, the time resource for transmitting the synchronization signal that is actually allocated by the network-side device is usually less than the time resource for transmitting the synchronization signal that is preset, so it is necessary to notify the terminal-side device of the position information of the time resource for transmitting the synchronization signal that is actually allocated by the network-side device in the time resource for transmitting the synchronization signal that is preset.

S41, the network device transmits the synchronization signal at the location of the configured time resource for transmitting the synchronization signal.

In S41, the synchronization signal has a function of indicating location information of the configured time resource for transmitting the synchronization signal in a preset time resource for transmitting the synchronization signal, as in S40. And the network side device sends the synchronous signal, the terminal side device which receives the synchronous signal detects the synchronous signal at the position of the configured time resource for sending the synchronous signal according to the synchronous signal.

And S42, the terminal side device receives the synchronous signal, wherein the synchronous signal is used for indicating the position information of the configured time resource for transmitting the synchronous signal in the preset time resource for transmitting the synchronous signal.

And S43, the terminal side device detects the synchronous signal at the position of the configured time resource for sending the synchronous signal according to the synchronous signal.

In the method of this embodiment, the synchronization signal has a new function for indicating the location information of the configured time resource for transmitting the synchronization signal in the preset time resource for transmitting the synchronization signal. The method described in this embodiment can be used in various communication systems, and is not limited to the fifth generation communication NR, which is not limited in this application.

Further, the method is implemented not to transmit the synchronization signal in the preset time resource for transmitting the synchronization signal and at a position other than the configured time resource for transmitting the synchronization signal. I.e. the preset time resource for transmitting the synchronization signal and at a position other than the configured time resource for transmitting the synchronization signal, may be used as another purpose to improve the utilization of the wireless time resource, e.g. transmitting data information or other information, or not transmitting any information, etc.

Example two

The present embodiment specifically describes the method described in the present application, taking the fifth generation communication NR as an example.

The time resource design and the design of the synchronization signal in the fifth generation communication NR are shown in fig. 2.

In this context, the time resources in the fifth generation communication NR are newly designed, and the minimum time unit in the designed time resources corresponds to the scanned beam pair.

And, the synchronization signal in the fifth generation communication NR is carried on the minimum time unit, and the network side device repeats the synchronization signal on the beam of the round-robin scanning, so that the terminal side device searches for the cell.

Specifically, fig. 2 is a schematic diagram of time resource design and design of a synchronization signal in the fifth generation communication NR passed by the 86 th conference of the 3GPP RAN 1. As shown in fig. 2, the set of sync signal pulses SS burst is a predetermined period, one set of sync signal pulses SS burst includes a plurality of sync signal pulses SS burst, and one set of sync signal pulses SS burst includes a plurality of sync signal blocks SS block. The primary synchronization signal PSS and the secondary synchronization signal SSS are both mapped collectively within one SS block. In other words, the synchronization signal block SS block is the smallest time unit in the time resources in the fifth generation communication NR on which the synchronization signal is carried.

In this embodiment, the configured time resource for sending the synchronization signal refers to a configured synchronization signal block SS block; the preset time resource for transmitting the synchronization signal includes: a set of synchronization signal pulses SS burst set or synchronization signal pulses SS burst; the position information of the configured time resource for sending the synchronization signal in the preset time resource for sending the synchronization signal refers to a position of a synchronization signal block SS block configured by the network side device in a synchronization signal pulse set SS burst or a synchronization signal pulse SS burst.

Referring to fig. 3, a method for transmitting a synchronization signal includes:

s10, the network side device generates a synchronization signal, which is used to indicate the position of the configured synchronization signal block SS block in the set of synchronization signal pulses SS burst set or the synchronization signal pulses SS burst.

In S10, the network side device generates a synchronization signal indicating a location of the SS block configured by the network side device in various ways, which is not limited in the present application.

One of the generation methods is as follows:

and S101, the network side device determines a synchronization signal according to the number of the configured SS blocks.

For example, if the maximum value of the number of SS blocks in one preset period SS burst set configurable by the network-side device is N, if there are M optional synchronization signals, and M > N, each "number of configured SS blocks" may correspond to one of the M synchronization signals, respectively. I.e., a sync signal, may directly indicate a "number of configured SS blocks".

And S102, the network side device determines the position of the configured SS block according to the number of the configured SS block and a preset position mode.

The position mode in the S102 can be preset in a network side device and a terminal side device, and the position of the configured SS block can be determined according to the number of the configured SS block; that is, after the preset location mode is determined, a one-to-one correspondence relationship exists between synchronization signals, the number of configured SS blocks, and the locations of the configured SS blocks; a sync signal may indicate the "number of configured SS blocks" and/or the "location of configured SS blocks".

The location mode preset in S102 may include a plurality of types, for example, the location of the configured SS block in the SS burst set, or the location of the configured SS block in the SS burst.

The position of the configured SS block in the SS burst set includes, for example:

for example, the first m SS block positions in an SS burst set, where m is a natural number and is the number of configured SS blocks.

For example, the last m SS block positions in one SS burst set, where m is the number of configured SS blocks.

For example, m SS block positions are spaced from the 1 st SS block by x positions in an SS burst set, wherein m is the number of the configured SS blocks, x is the preset spacing number, x is less than n-m, and n is the total number of SS blocks in the SS burst set.

For example, m SS block positions are spaced from the last 1 SS block by x positions in an SS burst set, where m is the number of configured SS blocks, x is a preset spacing number, x is less than n-m, and n is the total number of SS blocks in the SS burst set.

The position of the configured SS block in the SS burst includes, for example:

for example, the first Xi SS block positions in the ith sync signal pulse SS burst, where i is a natural number, Xi is a natural number,

and m is the number of the configured synchronous signal blocks SS block, one synchronous signal pulse set SS burst set comprises n synchronous signal pulses SS burst, one SS burst comprises a plurality of synchronous signal blocks SS block, and Xi is a given determined value.

The preset position mode can be flexibly set in the network side device and the terminal side device according to the requirement, and the present application is not limited thereto.

And S11, the network side device sends the synchronization signal at the position of the configured synchronization signal block SS block.

In S11, as described in S10, in one embodiment, the number of configured SS blocks and the preset location mode may determine the locations of the configured SS blocks, and the network side device transmits the synchronization signal generated in S10 at the determined locations of the configured SS blocks.

And S12, the terminal side device receives a synchronization signal, wherein the synchronization signal is used for indicating the position of the configured synchronization signal block SS block in the synchronization signal pulse set SS burst or the synchronization signal pulse SS burst.

In S12, the terminal side device receives the synchronization signal transmitted by the network side device in S10.

And S13, the terminal side device detects the synchronizing signal at the position of the configured synchronizing signal block SS block according to the synchronizing signal.

In S13, the terminal side device stores the same configuration information as the network side device, which means the correspondence relationship mentioned in S101 and S102. For example, the terminal side device stores a corresponding relationship between the number of configured SS blocks and the synchronization signal, and the terminal side device stores a preset location mode selected by the network side device, so that the terminal side device can acquire the number of the configured SS blocks and/or the location of the configured SS blocks according to the received synchronization signal, and detect the synchronization signal at the location of the configured SS blocks, so as to achieve the effect of synchronization with the network side device.

In the method of this embodiment, the sync signal has a new function, and may be used to indicate the number of configured sync signal blocks SS block and/or the position of the configured sync signal blocks SS block in the set of sync signal pulses SS burst set or the location of the configured sync signal blocks SS burst.

Furthermore, the network side device sends data information or other information at the position in the synchronization signal pulse set SS burst or the synchronization signal pulse SS burst except the configured SS block position, so as to improve the utilization rate of wireless time resources.

EXAMPLE III

In this embodiment, a specific implementation manner of the second embodiment is implemented, where the number of the synchronization signals in the third embodiment is much smaller than the number of SS blocks in one synchronization signal pulse set SS burst set, and the third embodiment specifically solves the following problems: in this case, how the synchronization signal indicates the location information of the SS block configured by the network-side device.

In this embodiment, the position information of the configured synchronization signal block SS block refers to a position interval where the position of the configured synchronization signal block SS block is located, and specifically, the end position of the configured synchronization signal block SS block is located in the position interval of the synchronization signal pulse set SS burst or the synchronization signal pulse SS burst.

Fig. 4 is a flowchart illustrating a third embodiment of the present application.

Referring to fig. 4, a method for transmitting a synchronization signal includes:

and S20, the network side device generates a synchronization signal, wherein the synchronization signal is used for indicating the position interval of the end position of the configured synchronization signal block SS block in the synchronization signal pulse set SS burst or the synchronization signal pulse SS burst, and the start position of the configured synchronization signal block SS block is the same as the start position of the synchronization signal pulse set SS burst or the synchronization signal pulse SS burst.

In S20, when the number of SS blocks in one SS burst set is much larger than the number of sync signals, and the sync signals cannot correspond to the number of configured SS blocks one to one (described in the second S101), the number/position of SS blocks in one SS burst set may be divided into number intervals/position intervals, and the sync signals correspond to the divided number intervals/position intervals one to one, so as to achieve the purpose that the sync signals indicate the number intervals/position intervals where the configured SS blocks are located.

In S20, one method for the network side device to generate the synchronization signal is:

s201, the network side device determines the position interval of the configured SS blocks in a synchronizing signal pulse set SS burst set or a synchronizing signal pulse SS burst according to the number of the configured SS blocks and a preset position mode.

In S201, the location section where the configured SS blocks are located is related to the number of the configured SS blocks and a preset location mode. The preset position mode may include a plurality of types, which are specifically described in embodiment two and are not described herein again. The network side device and the terminal side device store the same preset position mode.

The present embodiment will be described below by taking two specific preset position patterns as examples.

One specific preset position pattern is: and the first m SS block positions in one SS burst set, wherein m is a natural number, and m is the number of the configured SS blocks.

Table 1 shows a specific example of the preset position pattern.

TABLE 1

Synchronization signal	block number interval	block location interval
			S1	17-24	17 th block position-24 th block position
S2	9-16	9 th to 16 th block position
			S3	1-8	1 st block position to 8 th block position

In the example shown in table 1, one SS burst set contains 24 SS blocks, which are described as follows from the position point of view: from the 1 st block position to the 24 th block position. The 24 SS blocks are divided into 3 block number intervals: "1-8", "9-16", "17-24"; the 24 positions are divided into 3 position intervals: "1 st block position-8 th block position", "9 th block position-16 th block position", "17 th block position-24 th block position"; the 3 number intervals and the 3 position intervals correspond to the 3 synchronization signals one by one, as shown in table 1.

In the position mode shown in table 1, if the number of configured SS blocks is 12, the interval of the number of configured SS blocks is "9-16", the position interval of the end position of the configured SS block in the synchronization signal pulse set SS burst set is "9 th block position-16 th block position", and the synchronization signal corresponding to this is "S2". That is, the generated sync signal indicates the number section where the arranged SS blocks are located and the position section where the end position of the arranged SS blocks is in the sync signal burst set.

The preset position mode is the first m SS block positions from the 1 st block position in the synchronizing signal pulse set SS burst set, wherein m is a natural number, and m is the number of the configured SS blocks.

Another specific preset position pattern is:

the first Xi SS block positions in the ith sync signal pulse SS burst, where i is a natural number, Xi is a natural number,

Table 2 shows a specific example of another preset position pattern, where Xi ═ 5.

TABLE 2

Synchronization signal	SS burst
		S1	17 th block position-24 th block position (3)
S2	9 th block position-16 th block position (2)
		S3	Block position 1-block position 8 (1)

As shown in table 2, one SS burst set includes 3 SS bursts ("1 st block position-8 th block position", "9 th block position-16 th block position", "17 th block position-24 th block position"), each SS burst includes 8 block positions, and one SS burst set includes 24 SS blocks in total. The default location pattern in this example is filled with the first Xi locations of each SS burst, starting from the first SS burst, assuming Xi equal to 5 in this example.

In the position mode shown in table 2, if the number of configured SS blocks is 12, the positions of the configured SS blocks in the synchronization signal pulse SS burst are: the "1 st block position-5 th block position" of the 1 st SS burst, that is, the "1 st block position-5 th block position" in the SS burst set, the "1 st block position-5 th block position" of the 2 nd SS burst, that is, the "9 th block position-13 th block position" in the SS burst set, and the "1 st block position-2 nd block position" of the 3 rd SS burst, that is, the "17 th block position-18 th block position" in the SS burst set. That is, if the number of configured SS blocks is 12, the end position of the configured SS block is in the 3 rd SS burst (the SS burst itself is a block position interval), and the synchronization signal corresponding to the 3 rd SS burst is "S1". That is, the sync signal is "S1", and indicates an SS burst where the configured SS block end position is located (the SS burst itself is a block position interval).

And S202, the network side device generates a synchronization signal according to the number/number interval of the configured SS blocks and the position interval of the configured SS blocks, wherein the synchronization signal indicates the number interval and the position interval of the configured SS blocks.

In S202, as described in S201, there is a one-to-one correspondence relationship among the number interval of SS blocks, the position interval of SS blocks, and the synchronization signal, and S202 determines the synchronization signal according to the number/number interval of configured SS blocks and the position interval where the configured SS blocks are located.

In summary, in S20, the network-side device may determine the location interval where the configured SS block is located according to the number of the configured SS blocks and the preset location mode; the location interval, the number interval, and the synchronization signal are in one-to-one correspondence, and thus, the synchronization signal indicates the number interval and the location interval where the configured SS block is located.

And S21, the network side device sends the synchronization signal at the configured SS block position.

In S21, the configured SS block positions depend on the configured number of SS blocks and a preset position mode. For example, the preset location mode is shown in table 1, and if the configured SS block number is 12, the location of the configured SS block described in S21 is "1 st block location — 12 th block location". The network-side device transmits the synchronization signal "S2" generated in S201 at the 1 st block position to the 12 th block position.

In S21, it should be noted that the network-side device transmits the synchronization signal at an accurate SS block position, for example, at "1 st block position — 12 th block position"; however, in this embodiment, the terminal side device cannot resolve this hierarchy, and the terminal side device can only resolve the block number section where the configured SS block is located and the block position section where the configured SS block is located, for example, when the network side device sends the synchronization signal "S2" at "1 st block position to 12 th block position", the terminal side device can only determine that the block number section where the configured SS block is located at the network side device is "9 to 16", the block position section where the configured SS block is located is "1 st block position to 16 th block position", and it is determined that the network side device is not configured with 12 blocks, and the positions of the 12 SS blocks are "1 st block position to 12 th block position".

And S22, the terminal side device receives a synchronization signal, wherein the synchronization signal is used for indicating the end position of the configured synchronization signal block SS block in the synchronization signal pulse set SS burst set or the position interval of the synchronization signal pulse SS burst.

And S23, the terminal side device detects the synchronous signal according to the synchronous signal, wherein the end position of the configured synchronous signal block SS block is in the synchronous signal pulse set SS burst set or the position interval of the synchronous signal pulse SS burst.

In S23, the terminal-side device stores the same configuration information as the network-side device, which refers to the preset location pattern mentioned in S20. For example, if the network-side device and the terminal-side device store the preset location modes shown in table 1, the terminal-side device may obtain, according to the received synchronization signal, a block number interval in which the SS block configured by the network-side device is located and a block location interval in which the SS block configured by the network-side device is located. For example, if the terminal side device receives a synchronization signal "S2", it can be known that a block number interval in which an SS block configured by the network side device is located is "9-16", and a block position interval in which the configured SS block is located is "1 st block position-16 th block position"; the terminal-side device performs synchronization signal detection at "1 st block position — 16 th block position".

Firstly, after the network side device and the terminal side device agree on a block number interval where the configured SS block is located and a block position interval where the configured SS block is located, the network side device can send data information or other information at SS burst set or at a position in SS burst other than the block position interval where the configured SS block is located; continuing with the above example, the network-side device may transmit data information at "17 th block location — 24 th block location" to improve the radio time resource utilization. Accordingly, the terminal side device receives data information at the "17 th block position-24 th block position" to improve the radio time resource utilization rate.

The terminal side device stores the same configuration information as the network side device, wherein the configuration information refers to the preset position mode mentioned in the step S20; for another example, the network-side device and the terminal-side device store the preset location patterns shown in table 2, and if the terminal-side device receives the synchronization signal "S3", the terminal-side device can know that the location interval of the SS block configured by the network-side device is: the method comprises the following steps that (1) the 1 st block position-the 5 th block position of the 1 st SS burst, namely the 1 st block position-the 5 th block position in the SS burst set, the 1 st block position-the 5 th block position of the 2 nd SS burst, namely the 9 th block position-the 13 th block position in the SS burst set, and the 1 st block position-the y block position of the 3 rd SS burst, namely the 1 st block position-the y block position in the SS burst set, are less than or equal to 5; and the terminal side device detects the synchronous signal in the configured position section of the SS block.

In this embodiment, the synchronization signal is used to indicate a block number interval in which the configured synchronization signal block SS block is located and a block position interval in which the configured SS block is located.

In this embodiment, the indication function of the synchronization signal can only indicate a "section" level, including a block number section and a block position section, and the SS block time resource that can be used to transmit data information or other information is a time resource other than the "section", and the resource utilization rate is limited. If the number of configured SS blocks and the positions of the configured SS blocks need to be accurately indicated, other indication information needs to be combined, and a specific scheme can be seen in the following fourth embodiment.

Example four

The present embodiment is different from the third embodiment in that: in this embodiment, on the basis of the third embodiment, the network-side device generates and sends the position offset information/amount offset information, so that the terminal-side device knows the accurate amount and position of the SS blocks configured by the network-side device, and further, waste of some wireless time resources in a block amount interval in which the configured SS blocks are located is avoided.

Fig. 5 is a flowchart illustrating a fourth embodiment of the present application.

Referring to fig. 5, a method for transmitting a synchronization signal includes:

S30-S33；

S30-S33 are the same as S20-S23 in the third embodiment and are not repeated here.

S34, the network side device generates position offset information, where the position offset is an offset between an end position of the configured synchronization signal block SS block and a front end or a rear end value of a position section where the end position is located.

TABLE 1

In S34, continuing with the description given by taking table 1 in the third embodiment as an example, the configured SS block number m is 12, that is, the end position of the configured synchronization signal block SS block is "12 th block position", the position section where the 12 th configured SS block is located is "9 th block position to 16 th block position", the "12 th block position" is distant from "16 th block position" by 4 block positions, that is, the position offset amount is "4 block positions", and the "12 th block position" is distant from "9 th block position" by 3 block positions, that is, the position offset amount is "3 block positions".

The position offset information is carried by information in a synchronous access process or information in a data transmission process, for example, PBCH information in a physical broadcast channel in the synchronous access process, and RRC signaling information in the data transmission process.

The position offset information may be represented by bit information, for example, if the block position interval length in table 1 is 8, and 3-bit information is required to represent, then "4 blocks" may be represented by "100".

In summary, in one possible embodiment, the location offset information may be a physical broadcast channel PBCH information carrying "100" or an RRC signaling information carrying "100".

TABLE 2

Taking table 2(Xi ═ 5) as an example, the configured SS block number m is 12, that is, the end position of the configured synchronization signal block SS block is the "2 nd block position" of the 3 rd SS burst (that is, the 18 th block position in the SS burst set), the "2 nd block position" is 1 block position away from the front end of the "3 rd SS burst", that is, the position offset amount is "1 block position", and the "2 nd block position" is 6 block positions away from the rear end of the "3 rd SS burst", that is, the position offset amount is "6 block positions". The bearing of the position offset is described above, and is not described herein again.

S35, the network side device sends the location offset information.

In S35, taking the preset location mode shown in table 1 as an example, as described in S34, the location offset information is carried by information in a synchronous access process or information in a data transmission process, and if the network side device sends the location offset information in the synchronous access process, the terminal side device may obtain a location offset in the synchronous access process, so as to obtain an accurate number of SS blocks configured by the network side device, and further, the terminal side device may receive data information or other information at a location other than a location where the accurate number of SS blocks configured is located as early as possible; for example, after S30-S33 (the terminal side device learns that the block number interval is "9-16", and the block position interval is "9 th block position-16 th block position"), if the network side device sends the PBCH information carrying "100", the terminal side device may learn that the accurate number of SS blocks configured by the network side device is 12 in the synchronous access process, and after the terminal side device completes the synchronous access, the terminal side device may receive the data information at 13 th block position-24 th block position, thereby improving the utilization rate of the wireless time resource as early as possible. Therefore, the position offset information is carried by the information in the synchronous access process, the position and the number of the SS blocks configured by the network side device can be indicated as early as possible, and the utilization rate of wireless time resources can be improved as early as possible.

If the network side device sends the position offset information in the data transmission process, the terminal side device receives data information or other information only at the position outside the block number interval where the configured SS block is located before receiving the position offset information, and receives the data information or other information at the position outside the position where the accurate number of the configured SS block is located after receiving the position offset information in the data transmission process. For example, after S30-S33, if the network side device sends RRC signaling information carrying "100", the terminal side device may only know that the block number interval where the configured SS block is located is "9-16", and the location interval is "9 th block location to 16 th block location" in the synchronous access process, and receive data information or other information only at 17 th block location to 24 th block location, until the terminal side device receives the RRC signaling information carrying "100", the terminal side device may only know that the accurate number of the SS blocks configured by the network side device is 12, and receive data information or other information at 13 th block location to 24 th block location. Therefore, the position offset information is carried by the information in the data transmission process, the number of the SS blocks configured by the network side device can be accurately indicated finally, the utilization rate of wireless time resources can be further improved, and the terminal side device can acquire the accurate number of the SS blocks configured by the network side device later in time compared with the information in the synchronous access process.

S36, the terminal device receives the positional offset information.

And S37, the terminal device does not perform synchronization signal detection at a position between the end position of the configured synchronization signal block SS block and the rear end value of the position section, based on the positional offset information.

In S37, the terminal side device learns the precise location of the SS block configured by the network side device, that is, the location between the end location of the configured synchronization signal block SS block and the rear end value of the location interval is not the location of the configured SS block, and does not perform synchronization signal detection at these locations.

In this embodiment, the synchronization signal, in combination with the position offset information, may accurately indicate the position and number of SS blocks configured by the network side device; the method can avoid the waste of some wireless time resources in the block position interval where the SS block configured by the network side device is located, and improve the utilization rate of the wireless time resources more.

Furthermore, when the position offset information adopts information in the synchronous access process, the number of SS blocks configured by the network side device can be accurately indicated as early as possible, and the utilization rate of wireless time resources can be improved as early as possible.
