Description

Indication and receiving method of synchronous signal block transmission position, network equipment and terminal

Technical Field

The invention relates to the technical field of communication, in particular to an indication and receiving method of a transmission position of a synchronous signal block, network equipment and a terminal.

Background

In the 5G standardization discussion, to support multi-beam operation, a plurality of synchronization signal blocks (SS blocks) are transmitted. A plurality of SS blocks forms a synchronization signal burst set (set of synchronization signal pulses). During a synchronization signal pulse set transmission period (or synchronization signal transmission period), the number of SS blocks that can be transmitted at the maximum per frequency band and the corresponding position have been determined.

3GHz below: l is 4, namely the maximum transmission of 4 SS blocks; subcarrier spacing of 15KHz and 30KHz may be used, and corresponding SS block patterns are shown in fig. 1 and 2;

3 GHz-6 GHz: l is 8, i.e. maximum transmission of 8 SS blocks; subcarrier spacing of 15KHz and 30KHz may be used, and corresponding SS block patterns may be transmitted as shown in fig. 3 and 4;

more than 6 GHz: l is 64, namely, the maximum transmission is 64 SS blocks; subcarrier spacing of 120KHz and 240KHz may be used, and corresponding SS block patterns may be transmitted as shown in fig. 5 and 6;

in actual transmission, the coverage, overhead and other conditions are considered comprehensively, the base station does not necessarily need to transmit SS blocks according to L (i.e., the maximum SS block number), and actually transmitted SS blocks can be fewer.

In the current SS block transmission position, a transmission pattern considering the coexistence requirement with LTE is proposed under the condition of 30KHz subcarrier spacing, as shown in fig. 7.

In fig. 7, when in a certain frequency band where LTE and NR coexist, the SS block that can be transmitted is only SS block1, and for the case where L is 4, at most 1 SS block can be transmitted in one period, as shown in the figure as SS block 1; in the case of L being 8, at most 2 SS blocks can be transmitted in one period.

Considering the coverage requirement of the NR synchronization channel, the coverage cannot be fully guaranteed by only 2 SS blocks, so a larger number of actual transmission SS blocks needs to be supported.

Taking the 3.5G coverage requirement as an example, in order to achieve the same coverage as 1.9G, PBCH needs to be enhanced by more than 4dB, so 3-4 SS blocks are needed;

therefore, if only 2 SS blocks can be actually transmitted in the frequency band due to the limitation of LTE, the coverage area of the NR cell is greatly limited, which is not favorable for NR deployment.

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 disclosure to those skilled in the art.

The embodiment of the invention provides a method for indicating the transmission position of a synchronous signal block, which comprises the following steps:

Specifically, broadcast information is sent to a terminal, where the broadcast information carries first indication information indicating a transmission resource location of a synchronization signal block that is actually transmitted, the first indication information is indicated by N bits, and N is a positive integer greater than or equal to 2.

For example, in a synchronization signal transmission period or a synchronization signal pulse set transmission period, the number of the synchronization signal blocks that are most likely to be transmitted is L, and then in this period, for example, L ═ 4, a maximum of 4 bits may be used for indication; l-8, a maximum of 8 bits may be used for indication; l-64, a maximum of 64 bits may be used for indication.

For example, in a scenario where 5G NR and LTE coexist, it can be determined that the following situations are required to be included in the transmission resource location of the synchronization signal block that needs to be indicated:

when L is 4, as shown in fig. 7, in a coexistence scenario where a 5G NR is deployed with a 4-port CRS LTE, a synchronization signal block that can be actually transmitted in an NR system is SS block1, because there is no CRS transmitted on a corresponding symbol in a transmission slot in the LTE system corresponding to SS block1, at this time, 2 bits may be used for indication, for example: 00 or 01 or 10 or 11, which is used to indicate that the actually transmitted synchronization signal Block is a symbol corresponding to SS Block 1.

When L is 4, as shown in fig. 8, in a coexistence scenario where a 5G NR is deployed with a 2-port/1-port CRS LTE, in an NR system, synchronization signal blocks that can be actually transmitted are SS block1 and SS block 3. At this time, 2 bits may be used for indication, such as: 00 or 01 or 10 or 11, for indicating that the actually transmitted sync signal Block is SS Block1, and the other for indicating SS Block 3;

when L is 8, under a coexistence scene with a 4-port CRS LTE deployed by a 5G NR, in an NR system, synchronization signal blocks which can be actually transmitted are SS block1 and SS block 5; at this time, 2 bits may be used for indication, such as: 00 or 01 or 10 or 11 for indicating that the actually transmitted sync signal Block is SS Block1, and the other for indicating SS Block 5;

when L is 8, under a coexistence scene deployed with 2-port/1-port CRS LTE, in an NR system, synchronization signal blocks which can be actually transmitted are SS block1, SS block3, SS block 5, and SS block 7; such as: 00 is used to indicate SS Block1, 01 is used to indicate SS Block3, 10 is used to indicate

SS Block

5, 11 is used to indicate SS Block 7.

In the scheme, the transmission scheme of the synchronization signal block which can be determined under the coexistence requirement of NR and LTE is considered. When L is obtained as 4/8, at least 3 states need to be indicated, and 2 bits can be used for indication.

It can be seen that, considering the actual deployment requirement, some synchronization signal blocks cannot be transmitted or do not need to be transmitted, so that it is not necessary to completely indicate all combinations of the actually transmitted synchronization signal blocks, that is, according to the deployment requirement and the actual transmission mode of the LTE network, the synchronization signal block which should be actually transmitted is selected from the synchronization signal blocks, so that other unnecessary transmission resources can be well excluded, and thus the signaling overhead can be reduced.

On the other hand, on the frequency band without coexistence requirement, the problems of terminal energy consumption and uplink and downlink interference are considered comprehensively, and the transmission resources required for actually transmitting the synchronization signal block are concentrated on the initial time slot of a synchronization period as much as possible, so that the method is beneficial to terminal measurement, energy conservation, reservation of a larger time length in uplink and downlink transmission to avoid uplink and downlink interference and the like.

According to the above analysis, according to the requirement that the actually transmitted synchronization signal blocks are as concentrated as possible, it can be determined that the synchronization signal blocks which need to be indicated need to include the following situations:

(one) when L is 4,

the actually transmittable synchronization signal block is SS block 1;

or the actually transmitted synchronization signal blocks may be SS block1 and SS block 2;

or the actually transmitted synchronizing signal blocks can be SS block1, SS block2 and SS block 3;

the synchronization signal blocks which can be actually transmitted may be SS block1, SS block2, SS block3, and SS block 4.

(II) when L is 8,

the SS block pattern which can be actually transmitted is SS block 1;

the actually transmitted SS block pattern is SS block1, SS block 2;

the actually transmitted SS block patterns are SS block1, SS block2 and SS block 3;

the actually transmitted SS block patterns are SS block1, SS block2, SS block3 and SS block 4;

the actually transmitted SS block patterns are SS block1, SS block2, SS block3, SS block 4 and SS block 5;

the actually transmitted SS block patterns are SS block1, SS block2, SS block3, SS block 4, SS block 5 and SS block 6;

the actually transmitted SS block patterns are SS block1, SS block2, SS block3, SS block 4, SS block 5, SS block 6 and SS block 7;

the actually transmitted SS block patterns are SS block1, SS block2, SS block3, SS block 4, SS block 5, SS block 6, SS block 7 and SS block 8;

(iii) when L is 64,

the SS block pattern which can be actually transmitted is SS block 1;

the actually transmitted SS block pattern is SS block1 and SS block 2;

the actually transmitted SS block patterns are SS block1, SS block2 and SS block 3; …

The actual SS block pattern that can be transmitted is SS block1, 2,3,4,5,6,7,8, … 64

Furthermore, the number of actually transmitted synchronization signal blocks can be limited, for example, at most 2^ n synchronization signal blocks are transmitted, thereby further reducing the bit number of the indication.

The finally determined transmission resource location of the synchronization signal block required to be indicated on each frequency band may consider a single coexistence requirement, or consider a requirement for uplink and downlink interference avoidance, or both requirements, or may also consider more requirements.

In the foregoing embodiment of the present invention, the broadcast information further carries second indication information indicating a transmission state of a transmission resource location of an actually transmitted synchronization signal block, where the second indication information is indicated by M bits, and M is a positive integer greater than or equal to 1.

Such as: as shown in the following table, the following,

bit (second indication information)	Status of transmission	First indication information
			00	Transmission state 1	First indication information 1
01	Transmission state 2	First indication information 2
			10	Transmission state 3	First indication information 3
11	Transmission state 4	First indication information 4

Specifically, 2^MIn the transmission states, a transmission resource location of an actually transmitted synchronization signal block indicated by first indication information corresponding to a first transmission state includes: a first synchronization signal block transmitted on each frequency band in one synchronization signal transmission period; or

2^MIn the transmission states, the transmission resource location of the actually transmitted synchronization signal block indicated by the first indication information corresponding to the fourth transmission state includes: transmitting on each frequency band in a synchronization signal transmission periodThe first, third, fifth and seventh synchronization signal blocks; or

Wherein the first transmission state is: the maximum transmission number of the synchronization signal blocks on each frequency band in the synchronization signal transmission period is 4, an LTE system and an NR system coexist, and the LTE system is in a transmission state under the scene of transmitting CRS (cell reference signal) by 4 ports;

the second transmission state is: the maximum transmission number of the synchronous signal blocks on each frequency band in the synchronous signal transmission period is 4, an LTE system and an NR system coexist, and the LTE system is in a transmission state under the condition that CRS is transmitted by a 2-port or 1-port;

the third transmission state is: the number of the maximum transmission synchronization signal blocks on each frequency band in the synchronization signal transmission period is 8, an LTE system and an NR system coexist, and the LTE system is in a transmission state under the condition that CRS is transmitted by 4 ports;

the fourth transmission state is: the number of the maximum transmission synchronization signal blocks on each frequency band in the synchronization signal transmission period is 8, the LTE system and the NR system coexist, and the LTE system is in a transmission state under the condition that CRS is transmitted by a 2-port or 1-port;

the fifth transmission state is: the maximum number of the transmitted synchronization signal blocks in each frequency band in the synchronization signal transmission period is 4 or 8, and the transmission state under the scene of uplink and downlink interference is avoided, that is, the actually transmitted synchronization signal blocks should be concentrated on the initial time slot of one synchronization period as much as possible.

These two requirements are exemplified below:

in the first example, the first step is,

the first condition is as follows: only the actual transmission synchronization signal block transmission mode under the coexistence requirement of the 5G NR system and the LTE is considered:

transmission of a set of sync signal block pulses of 4, 30KHz, with 2 bits indicating the transmission position where the sync signal block is actually transmitted;

transmission state 1: indicating that the actual transmission is SS block1, 2,3,4, simply 1111;

transmission state 2: 1010, which represents that the 1 st SS block and the 3 rd SS block are actually transmitted synchronization signal blocks, and correspond to a 5G NR and 2 port/1 port CRS LTE coexistence scene;

transmission state 3: 1000, corresponding to a 5G NR and 4 port CRS LTE coexistence scenario;

the states may also be considered: 1100, indicating a full 4 states with 2 bits;

as shown in the following table

The case corresponding to the transmission state 3 in the table is the case corresponding to the first transmission state, and the case corresponding to the transmission state 2 is the case corresponding to the second transmission state. In this table, when the second indication information is indicated by M bits, it is indicated at 2^MOf the transmission states, there may be a reserved transmission state, such as transmission state 4 described above.

Can also be

The case corresponding to the transmission state 4 in the table is the case corresponding to the first transmission state, and the case corresponding to the transmission state 2 is the case corresponding to the second transmission state.

The above indication method is not unique, and may be represented by the starting position of each synchronization block at the end of a time slot and/or all symbols actually occupied, where the starting position is + P symbols, and P is a positive integer greater than or equal to 1.

Case two:

transmission of a set of sync signal block pulses of 8, 30KHz, with 2 bits indicating the transmission position where the sync signal block is actually transmitted;

transmission state 1: 11111111

Transmission state 2: 10101010 → corresponding 2/1 port CRS LTE coexistence scenario

Transmission state 3: 10001000 → corresponding 4-port CRS LTE coexistence scenario

Transmission state 4: 10000000

As shown in the following table

In the table, the case corresponding to the transmission state 3 is the case corresponding to the third transmission state, and the case corresponding to the transmission state 2 is the case corresponding to the fourth transmission state, and in the table, when the second indication information adopts the M-bit indication, the M-bit indication is performed at 2^MOf the transmission states, there is also a reserved transmission state, such as transmission state 4 described above.
