Description

An information transmission method and network side device

technical field

The present invention relates to the field of communication technologies, and in particular, to an information transmission method and a network side device.

Background technique

With the advent of the fifth generation (5th generation, 5G) communication system, the working mode of the New Radio (NR) unlicensed frequency band access system (ie the NR-U system) needs to include support for carrier aggregation (Carrier Aggregation, for short). There are three working modes: CA), Dual Connection (DC for short), and Standalone (SA for short).

Compared with the traditional CA working mode, when the NR-U system works in the DC mode and the SA mode, it is also necessary for the base station to send synchronization signals and system messages on the unlicensed spectrum, including: NR Primary Synchronization Signal (Primary Synchronization Signal for short) PSS), NR Secondary Synchronization Signal (SSS), Physical Broadcast Channel (PBCH for short), first system information block (System Information Block 1, SIB1 for short) and other system messages (Other System Information, for short) OSI), such as SIB2, SIB3, SIB X, etc., where X is a certain natural number.

When the base station working in CA mode and the base station working in SA mode or DC mode coexist, because the system message sent by the base station working in SA mode or DC mode has higher channel access priority, therefore, the base station working in CA mode or DC mode has higher channel access priority. The performance of the base station in the mode of sending system messages will decrease, which reduces the transmission performance of the base station working in the CA mode. That is, when the base stations in each mode send messages on the unlicensed spectrum, the transmission performance of some base stations will be degraded due to the conflict of use of the spectrum.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to FIG. 1, FIG. 1 is a flowchart of an information transmission method provided by an embodiment of the present invention, which is applied to a network side device. As shown in FIG. 1, the method includes the following steps:

Step 101: Determine the value of the access capability parameter used when transmitting the first information in the first frequency band according to the mapping relationship between the load parameter of the first information and the access capability parameter.

Specifically, the first information includes a synchronous broadcast block (SS/PBCH Block, SSB for short), a first system information block, a master system message block (Master Information Block, MIB for short), other system information (Other System Information, referred to as OSI) and at least one of the paging messages. The first system information block is a system information block SIB1 (System Information Block 1, SIB1 for short).

There is a mapping relationship between the load parameter of the first information and the access capability parameter. According to the mapping relationship, the access capability parameter corresponding to the load parameter of the first information can be obtained, and the value of the load parameter of the first information is further determined. The value (the value of the load parameter can be understood as the information load indicated by the load parameter) corresponds to the value of the access capability parameter.

The mapping relationship between the load parameter of the first information and the access capability parameter can be understood as: the mapping relationship between the value of the load parameter and the value of the access capability parameter, according to the value of the load parameter, through the mapping relationship, the mapping relationship can be Obtain the value of the corresponding access capability parameter.

The mapping relationship between the load parameter of the first information and the access capability parameter. The mapping relationship can be defined by a table. For example, the first column in the table is the value of the load parameter, and the second column in the table is the access capability. The value of the parameter, wherein there is a mapping relationship between the value of the load parameter and the value of the access capability parameter in the same row. The mapping relationship can also be defined by a function, for example, the independent variable is the value of the load parameter, the dependent variable is the value of the access capability parameter, or the dependent variable is the value of the load parameter, and the independent variable is the value of the access capability parameter value.

In this embodiment, the value of the access capability parameter used when transmitting the first information in the first frequency band is determined according to the mapping relationship between the load parameter of the first information and the access capability parameter. The relationship acquires the value of the access capability parameter used when transmitting the first information in the first frequency band, and transmits the first information according to the value of the access capability parameter, and can flexibly adjust the transmission of the first information to improve the Transmission performance of network-side equipment.

For example, in the prior art, when the first network-side device works in the CA working mode and the second network-side device works in the SA mode or the DC mode, due to the system message sent by the network-side device working in the SA mode or the DC mode It has a higher channel access priority. Therefore, the performance of the network side device working in the CA mode to send system messages will be reduced, which reduces the transmission performance of the network side device working in the CA mode.

However, in the information transmission method provided in this embodiment, by setting the value of the access capability parameter of the first information (the value of the access capability parameter corresponds to the channel access capability), the first network-side device and the second network can be balanced. The reliability of the side device when transmitting the first information, and multiple unlicensed systems (it can be understood as a first network-side device that uses an unlicensed frequency band to transmit the first information and a second network-side device that does not transmit the first information) equitable coexistence of contradictions.

First, focus on the reliability of the first network-side device and the second network-side device when transmitting the first information.

The mapping relationship satisfies the following conditions:

For any two first load parameters and second load parameters, if the information load indicated by the first load parameter is greater than the information load indicated by the second load parameter, the access capability of the first channel is not stronger than that of the second channel access capability.

Wherein, the first channel access capability corresponds to the first access capability parameter corresponding to the first load parameter, and the second channel access capability corresponds to the second access capability parameter corresponding to the second load parameter .

That is, when the information load indicated by the first load parameter is greater than the information load indicated by the second load parameter, the first channel access capability is weaker than or equal to the second channel access capability. It can be understood that the channel access capability is a decreasing function of the information load indicated by the load parameter, and the decreasing function may be a monotonically decreasing function or a step function.

When the channel access capability is a monotonically decreasing function of the information load indicated by the load parameter, if the information load indicated by the first load parameter is greater than the information load indicated by the second load parameter, the first channel access capability is weaker than the information load indicated by the second load parameter. Two-channel access capability.

When the channel access capability is a decreasing function of the information load indicated by the load parameter, and the decreasing function is a step function, if the information load indicated by the first load parameter is greater than the information load indicated by the second load parameter, the first The channel access capability is weaker than or equal to the second channel access capability, as shown in the schematic diagram of the step function in Figure 2, where XA represents the information load indicated by the first load parameter, XB represents the information load indicated by the second load parameter, and the corresponding Yes, it can be concluded from FIG. 2 that the access capability of the first channel is Y1, and the access capability of the second channel is Y1. That is, the information load indicated by the first load parameter of an interval is allowed to correspond to the same channel access capability.

In FIG. 2 , XC represents the information load indicated by the third load parameter, and Y2 is the third channel access capability. XB is greater than XC, and Y2 is greater than Y1, that is, when the information load indicated by the second load parameter is greater than the information load indicated by the third load parameter, the second channel access capability is weaker than the third channel access capability.

In the mapping relationship in this embodiment, for any two first load parameters and second load parameters, if the information load indicated by the first load parameter is greater than the information load indicated by the second load parameter, the first channel is connected to the In this way, if the information load indicated by the first load parameter is heavy, because the access capability of the first channel is not stronger than that of the second channel, at this time, the first channel can be reduced. The probability that the information load indicated by the load parameter occupies the first frequency band for transmission for a long time improves the transmission performance of the network-side device for the information load indicated by the second load parameter.

Further, when the channel access capability is a decreasing function of the information load indicated by the load parameter, and the decreasing function is a step function, the mapping relationship should also satisfy:

There are at least a third load parameter and a fourth load parameter, and when the information load indicated by the third load parameter is greater than the information load indicated by the fourth load parameter, the access capability of the third channel is weaker than that of the fourth channel. access capability; the third channel access capability corresponds to the third access capability parameter corresponding to the third load parameter; the fourth channel access capability corresponds to the fourth access capability parameter corresponding to the fourth load parameter .

As shown in FIG. 3 , XD in FIG. 3 represents the information load indicated by the third load parameter, Y2 is the third channel access capability; XE represents the information load indicated by the fourth load parameter, and Y1 is the fourth channel access capability. XE is greater than XD, and Y1 is less than Y2, that is, when the information load indicated by the third load parameter is greater than the information load indicated by the fourth load parameter, the third channel access capability is weaker than the fourth channel access capability.

Further, the access capability parameter used when transmitting the first information includes at least one of the following parameters: an energy detection threshold (ie, Energy detection threshold) and a channel access priority class (ie, ChannelAccess Priority Class).

Specifically, when the access capability parameter used when transmitting the first information includes an energy detection threshold, for any two first load parameters and second load parameters, if the information load indicated by the first load parameter is loaded is greater than the information load indicated by the second load parameter, the energy detection threshold used when transmitting the first information is not greater than the energy detection threshold used when transmitting the second information;

and / or,

When the access capability parameter used when transmitting the first information includes the channel access priority category, for any two first load parameters and second load parameters, if the information load indicated by the first load parameter is loaded If the information load is greater than the information load indicated by the second load parameter, the channel access priority type used when transmitting the first information is not less than the channel access priority type used when transmitting the second information.

The energy detection threshold is an increasing function of the channel access capability, that is, the larger the value of the energy detection threshold, the stronger the channel access capability. Since the channel access capability is a decreasing function of the information load indicated by the load parameter, the energy detection threshold is also a decreasing function of the information load indicated by the first load parameter, and the decreasing function here may be a monotonically decreasing function or a step function.

The channel access priority class (refer to the channel access priority mechanism defined in 3GPP LAA and NR-U technology) is a decreasing function of the channel access capability, that is, the smaller the channel access priority class, the corresponding The higher the channel access priority, the stronger the channel access capability. Since the channel access capability is a decreasing function of the information load indicated by the load parameter, the channel access priority category is an increasing function of the information load indicated by the first load parameter, and the increasing function here may be a monotonically increasing function or a step function .

The following focuses on the fair coexistence problem between multiple unlicensed systems (it can be understood as a first network-side device that uses an unlicensed frequency band to transmit the first information and a second network-side device that does not transmit the first information), and focuses on the first information Fair coexistence issues with traffic channels.

In an embodiment, when only one channel access capability is used for the traffic channel (for example, a certain energy detection threshold value is used), the strongest channel access capability of the first information is designed to be higher than the channel access capability of the traffic channel. is stronger, and the weakest channel access capability of the design first information is the same as or weaker than the channel access capability of the traffic channel.

In this way, when the load of the first information is low, the channel access capability for transmitting the first information can be improved, making it far stronger than the channel access capability of the traffic channel, so as to improve the reliability of the transmission of the first information (such as a broadcast channel). sex. Conversely, when the load of the first information is too high, the channel access capability for transmitting the first information can be reduced to be equal to or slightly weaker than the channel access capability of the traffic channel, so as to take into account other networks that do not need to transmit broadcast channels. Channel access capability of the side device.

Further, when the access capability parameter used when transmitting the first information includes an energy detection threshold, the maximum value of the energy detection threshold used when transmitting the first information is less than or equal to the energy detection threshold of the traffic channel. The sum value of T1 and/or the minimum value of the energy detection threshold is less than or equal to the energy detection threshold of the traffic channel, where T1 is a constant.

In one embodiment, the first information is a broadcast channel. The energy detection threshold of the traffic channel may be set to -72dBm, the minimum value of the energy detection threshold of the broadcast channel can be set to -72dBm, and the maximum value of the energy detection threshold of the broadcast channel can be set to -72dB+T1= -62dBm, where T1=10dB.

Since the energy detection threshold of the broadcast channel is an increasing function of the channel access capability, it is a decreasing function of the broadcast channel load. That is, when the broadcast channel load is small, the energy detection threshold of the broadcast channel is close to the maximum value (-62dBm), that is, the channel access capability of the broadcast channel (-62dBm) is much higher than that of the traffic channel (-72dBm); When the broadcast channel load is large, the energy detection threshold of the broadcast channel is close to the minimum value (-72dBm). The coexistence capability of the system that needs to use the channel occupied by the broadcast channel) and the system (the system that is using the broadcast channel) reduces the difficulty of accessing the channel occupied by the broadcast channel for the traffic channels of other systems.

In another embodiment, when the traffic channel adopts multiple channel access capabilities (for example, multiple channel access priority class values are used), the strongest channel access capability of the first information and the highest channel access capability of the traffic channel are designed. The strong channel access capability is the same or stronger, and the weakest channel access capability of the design first information is equal to or weaker than the weakest channel access capability of the traffic channel.

In this way, when the load of the first information is low, the channel access capability for transmitting the first information can be improved, making it far stronger than the channel access capability of the traffic channel, so as to improve the reliability of the transmission of the first information (such as a broadcast channel). sex. Conversely, when the load of the first information is too high, the channel access capability for transmitting the first information can be reduced to be equal to or slightly weaker than the channel access capability of the traffic channel, so as to take into account other networks that do not need to transmit broadcast channels. Channel access capability of the side device.

Further, when the access capability parameter used when transmitting the first information includes a channel access priority class, the maximum value of the channel access priority class used when transmitting the first information is less than or equal to The maximum value of the channel access priority category of the traffic channel; and/or the minimum value of the channel access priority category of the traffic channel is greater than or equal to the minimum value of the channel access priority category of the traffic channel.

In one embodiment, the first information is a broadcast channel. It may be advisable to set the value range of the channel access priority category of the traffic channel to be [1, 2, 3, 4], where category 1 represents the highest channel access priority, and category 4 represents the lowest channel access priority . The value range of the channel access priority category of the broadcast channel can be set to [1, 2, 3].

Since the channel access priority category of the broadcast channel is a decreasing function of the channel access capability, it is an increasing function of the broadcast channel load. That is, when the broadcast channel load is small, the channel access priority category of the broadcast channel is close to the minimum value (category 1), that is, the strongest channel access capability (category 1) of the broadcast channel is equivalent to the strongest channel access capability of the traffic channel. When the broadcast channel load is large, the channel access priority category of the broadcast channel is close to the maximum value (category 3). At this time, the weakest channel access capability (3) of the broadcast channel is slightly stronger than that of the traffic channel. Channel access capability (category 4) to ensure the transmission reliability of the broadcast channel.

Further, the load parameter is at least one of the following information:

The actual number of SSBs transmitted during the SSB repetition period;

The statistical average of the number of SSBs transmitted in the first time period;

In the second time period, the statistical average of the number of bits used for transmitting the first information;

In the third time period, the statistical average of the number of resources used for transmitting the first information;

In the fourth time period, the statistical average of the number of bits used for transmitting the predetermined type of information in the first information;

In the fifth time period, the statistical average value of the amount of resources used for transmitting the predetermined type of information in the first information.

Specifically, the first time period may be a preset time period, such as 80ms, 20ms, 10ms, 5ms, etc., which is not limited herein. Each of the second to fifth time periods may be the same as or different from the first time period.

The determination of the statistical average value includes: (A/B)*C, the A is the value in the statistical period, the B is the time length of the statistical period, the C is the length of the Xth time period, and the The B is greater than the C. Specifically, B is much larger than C. X is the first time period, or the second time period, or the third time period, or the fourth time period, or the fifth time period.

When the first information is SSB, the load parameter may be determined according to the actual number of SSBs transmitted in the SSB repetition period, or the statistical average value of the number of transmitted SSBs in the first time period. The load parameter is used to determine the channel access capability corresponding to the first information, such as an energy detection threshold used when transmitting the first information, and/or a channel access priority.

When the first information is the first OSI, the load parameter may be determined according to the statistical average of the number of bits used by the first OSI in the second time period, or the statistical average of the number of resources used by the first OSI. The unit of the resource quantity is a resource element (Resource Element, RE for short) or a physical resource block (Physical RB, PRB for short).

When the load parameter is: in the fourth time period, the statistical average of the number of bits used to transmit the predetermined type of information in the first information, it can be understood that according to a typical broadcast channel (the predetermined type of information includes SSB, The overall overhead of SIB1, at least one OSI), such as the overall number of transmitted bits of all predetermined types of information within the fourth time period, or the overall number of resources occupied by all predetermined types of information within the fourth time period, determine any member information ( That is, the channel access capability of any predetermined type of information).

The above predetermined types may include one or more of SSB, SIB1, at least one OSI, and Paging messages. For example, it may include only SIB1, or SIB1 and at least one OSI, etc., or may include SSB, SIB1, at least one OSI, and a paging message at the same time, which is not limited here.

Further, the first frequency band may be an unlicensed frequency band, and/or the first frequency band adopts frame structure 3 .

3GPP proposes a concept of Long Term Evolution (LTE Assisted Access, LAA for short) to use unlicensed spectrum with the help of LTE licensed spectrum. A new frame structure (frame structure 3) is used in LAA, which is used by the secondary serving cell. In frame structure 3, all communication devices (such as base stations or terminals) need to perform a channel access procedure (Channel Access Procedure) before performing signal transmission. Only after the channel access procedure determines that the channel is idle, the communication device can occupy the channel for signal transmission.

When the network-side device sends the first information on the unlicensed frequency band, and there are many devices using the unlicensed frequency band, it will cause conflict in the use of the unlicensed frequency band, resulting in the degradation of the transmission performance of some network-side devices. At this time, the network-side device The value of the access capability parameter used when transmitting the first information in the first frequency band can be obtained according to the mapping relationship, and the first information can be transmitted according to the value of the access capability parameter, which can flexibly adjust the network-side device's response to the first information. transmission to improve the transmission performance of network-side equipment.
