Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information transmission method and a network side device.
Background
With the coming of the fifth generation (5th generation, abbreviated as 5G) communication system, the working modes of the New Radio (NR) unlicensed frequency band access system (i.e., NR-U system) need to include three working modes of supporting Carrier Aggregation (CA), Dual Connectivity (DC), and independent deployment (SA).
Compared with the conventional CA operating mode, when the NR-U system operates in the DC mode and the SA mode, it is further required to implement that the base station transmits the synchronization signal and the system message on the unlicensed spectrum, including: NR Primary Synchronization Signal (PSS), NR Secondary Synchronization Signal (SSS), Physical Broadcast Channel (PBCH), first System Information Block (SIB 1), and Other System Information (OSI), such as SIB2, SIB3, SIB X, and the like, where X is a natural number.
When the base station operating in the CA mode coexists with the base station operating in the SA mode or the DC mode, since the system message transmitted by the base station operating in the SA mode or the DC mode has a higher channel access priority, the performance of the base station operating in the CA mode to transmit the system message may be reduced, which reduces the transmission performance of the base station operating in the CA mode. That is, when the base station in each mode transmits a message on the unlicensed spectrum, the transmission performance of some base stations may be degraded due to the collision of the use of the spectrum.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, 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 in an embodiment of the present invention, and is applied to a network side device, as shown in fig. 1, the method includes the following steps:
Specifically, the first Information includes at least one of a synchronization broadcast Block (SS/PBCH Block, abbreviated as SSB), a first system Information Block, a main system message Block (Master Information Block, abbreviated as MIB), Other system messages (OSI), and a paging message. The first System Information Block is a System Information Block SIB1(System Information Block 1, SIB1 for short).
The load parameter of the first information and the access capability parameter have a mapping relationship, 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 access capability parameter corresponding to the value of the load parameter of the first information (the value of the load parameter can be understood as the information load indicated by the load parameter) is further determined.
The mapping relationship between the load parameter and the access capability parameter of the first information may be understood as: and obtaining the value of the corresponding access capability parameter through the mapping relation according to the value of the load parameter.
The mapping relationship between the load parameter and the access capability parameter of the first information may be defined by a table, for example, a first column in the table is a value of the load parameter, and a second column in the table is a value of the access capability parameter, where there is a mapping relationship between the values of the load parameter and the access capability parameter in the same row. The mapping relationship may also be defined by a function, for example, the independent variable is a value of the load parameter, the dependent variable is a value of the access capability parameter, or the dependent variable is a value of the load parameter, and the independent variable is a value of the access capability parameter.
In this embodiment, according to the mapping relationship between the load parameter of the first information and the access capability parameter, the value of the access capability parameter used when the first information is transmitted in the first frequency band is determined, so that the network side device obtains the value of the access capability parameter used when the first information is transmitted in the first frequency band according to the mapping relationship, and transmits the first information according to the value of the access capability parameter, and the transmission of the first information can be flexibly adjusted, so as to improve the transmission performance of the network side device.
For example, in the prior art, when the first network-side device operates in the CA operating mode and the second network-side device operates in the SA mode or the DC mode, since the system message sent by the network-side device operating in the SA mode or the DC mode has a higher channel access priority, the performance of the network-side device operating in the CA mode for sending the system message may be reduced, and the transmission performance of the network-side device operating in the CA mode may be reduced.
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 reliability of the first network-side device and the second network-side device in transmitting the first information may be balanced, and the contradiction between the fair coexistence of the multiple unlicensed systems (which may be understood as a first network-side device that transmits the first information using an unlicensed frequency band and a second network-side device that does not transmit the first information) may be balanced.
First, the reliability of the first network side device and the second network side device in the transmission of the first information is concerned.
The mapping relation satisfies the following conditions:
for any 2 first load parameters and second load parameters, if the information load indicated by the first load parameters is greater than the information load indicated by the second load parameters, the first channel access capability is not stronger than the second channel access capability.
The first channel access capability corresponds to a first access capability parameter corresponding to a first load parameter, and the second channel access capability corresponds to a second access capability parameter corresponding to a 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. This may be understood as the channel access capability being a decreasing function of the information load indicated by the load parameter, which 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 second 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 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 fig. 2, where XA represents the information load indicated by the first load parameter, and XB represents the information load indicated by the second load parameter, and accordingly, as can be seen from fig. 2, the first channel access capability is Y1, and the second channel access capability is Y1. I.e. the information load indicated by the first load parameter for an interval is allowed to correspond to the same channel access capability.
XC in fig. 2 denotes the information load indicated by the third load parameter, and Y2 is the third channel access capability. And when the XB is larger than XC, and Y2 is larger than Y1, namely the information load indicated by the second load parameter is larger 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 2 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 access capability is not stronger than the second channel access capability, so that if the information load indicated by the first load parameter is large, because the first channel access capability is not stronger than the second channel access capability, at this time, the probability that the information load indicated by the first load parameter occupies the first frequency band for a long time for transmission can be reduced, and the transmission performance of the network side device for the information load indicated by the second load parameter can be improved.
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 further satisfy:
at least a third load parameter and a fourth load parameter exist, and under the condition that 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; the third channel access capability corresponds to a third access capability parameter corresponding to a third load parameter; the fourth channel access capability corresponds to a fourth access capability parameter corresponding to a fourth load parameter.
As shown in fig. 3, XD in fig. 3 represents the information load indicated by the third load parameter, and Y2 is the third channel access capability; XE denotes the information load indicated by the fourth load parameter and Y1 is the fourth channel access capability. XE is larger than XD and Y1 is smaller than Y2, i.e. in case the information load indicated by the third load parameter is larger 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 in transmitting the first information includes at least one of the following parameters: an Energy detection threshold (i.e., Energy detection threshold) and a channel access Priority Class (i.e., ChannelAccess Priority Class).
Specifically, under the condition that the access capability parameter adopted when the first information is transmitted includes an energy detection threshold, for any 2 first load parameters and second load parameters, if the information load indicated by the first load parameters is greater than the information load indicated by the second load parameters, the energy detection threshold adopted when the first information is transmitted is not greater than the energy detection threshold adopted when the second information is transmitted;
and/or the presence of a gas in the gas,
under the condition that the access capability parameters adopted when the first information is transmitted comprise channel access priority classes, for any 2 first load parameters and second load parameters, if the information load indicated by the first load parameters is greater than the information load indicated by the second load parameters, the channel access priority classes adopted when the first information is transmitted are not less than the channel access priority classes adopted when the second information is transmitted.
The energy detection threshold is an increasing function of the channel access capability, i.e. the larger the value of the energy detection threshold is, the stronger the channel access capability is. 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, where the decreasing function may be a monotonically decreasing function or a step function.
The channel access priority class (see the channel access priority mechanism defined in 3GPP L AA and NR-U technologies) is a decreasing function of the channel access capability, i.e. the smaller the channel access priority class is, the higher the channel access priority it corresponds to, i.e. the stronger the channel access capability.
In the following, a fair coexistence problem between multiple unlicensed systems (which may be understood as a first network-side device that transmits first information using an unlicensed frequency band and a second network-side device that does not transmit the first information) is focused, and a fair coexistence problem between the first information and a traffic channel is focused.
In an embodiment, when the traffic channel only uses one channel access capability (e.g., uses a certain energy detection threshold value), the strongest channel access capability of the first information is designed to be stronger than the channel access capability of the traffic channel, and the weakest channel access capability of the first information is designed to be the same as or weaker than the channel access capability of the traffic channel.
Therefore, when the load of the first information is lower, the channel access capability for transmitting the first information can be improved, so that the channel access capability is far stronger than that of the service channel, and the transmission reliability of the first information (such as a broadcast channel) is improved. On the contrary, when the load of the first information is too high, the channel access capability of transmitting the first information can be reduced to be equal to or slightly weaker than the channel access capability of the service channel, so as to give consideration to the channel access capability of other network side devices which do not need to transmit the broadcast channel.
Further, in the case that the access capability parameter used in transmitting the first information includes an energy detection threshold, a maximum value of the energy detection threshold used in transmitting the first information is less than or equal to a sum of the energy detection threshold of a traffic channel and T1, and/or a 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. Without setting the energy detection threshold of the traffic channel to-72 dBm, the minimum value of the energy detection threshold of the broadcast channel may be set to-72 dBm, and the maximum value of the energy detection threshold of the broadcast channel may be set to-72 dB + T1-62 dBm, where T1-10 dB.
Since the energy detection threshold of the broadcast channel is an increasing function of the channel access capability and a decreasing function of the broadcast channel load. When the load of the broadcast channel is small, the energy detection threshold of the broadcast channel is close to the maximum value (-62dBm), namely the channel access capability (-62dBm) of the broadcast channel is far higher than the channel access capability (-72dBm) of the service channel; when the load of the broadcast channel is larger, the energy detection threshold of the broadcast channel is close to the minimum value (-72dBm), at this time, the channel access capability of the broadcast channel (-72dBm) and the service channel are close to (-72dBm), the coexistence capability of other systems (systems which need to use the channel occupied by the broadcast channel) and the system (systems which use the broadcast channel) is improved, and the difficulty of accessing the service channel of other systems to the channel occupied by the broadcast channel is reduced.
In another embodiment, when the traffic channel adopts multiple channel access capabilities (e.g., multiple channel access priority class values), the strongest channel access capability of the first information is designed to be the same as or stronger than the strongest channel access capability of the traffic channel, and the weakest channel access capability of the first information is designed to be the same as or weaker than the weakest channel access capability of the traffic channel.
Therefore, when the load of the first information is lower, the channel access capability for transmitting the first information can be improved, so that the channel access capability is far stronger than that of the service channel, and the transmission reliability of the first information (such as a broadcast channel) is improved. On the contrary, when the load of the first information is too high, the channel access capability of transmitting the first information can be reduced to be equal to or slightly weaker than the channel access capability of the service channel, so as to give consideration to the channel access capability of other network side devices which do not need to transmit the broadcast channel.
Further, when the access capability parameter used in transmitting the first information includes a channel access priority category, a maximum value of the channel access priority category used in transmitting the first information is less than or equal to a maximum value of a channel access priority category of a traffic channel; and/or the minimum value of the channel access priority class is greater than or equal to the minimum value of the channel access priority class of the traffic channel.
In one embodiment, the first information is a broadcast channel. The value range of the channel access priority class of the traffic channel is set to [1,2,3,4], where the class 1 represents the highest channel access priority and the class 4 represents the lowest channel access priority. The value range of the channel access priority class of the broadcast channel may be set to [1,2,3 ].
Since the channel access priority class of a broadcast channel is a decreasing function of the channel access capability and an increasing function of the broadcast channel load. That is, when the broadcast channel is less loaded, the channel access priority class of the broadcast channel is close to the minimum (class 1), that is, the strongest channel access capability (class 1) of the broadcast channel is equal to the strongest channel access capability of the traffic channel; and when the load of the broadcast channel is larger, the channel access priority class of the broadcast channel is close to the maximum value (class 3), and at the moment, the weakest channel access capability (3) of the broadcast channel is slightly stronger than the weakest channel access capability (class 4) of the service channel, so as 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 an SSB repetition period;
a statistical average of the number of transmitted SSBs over a first time period;
transmitting a statistical average of the number of bits used by the first information in a second time period;
transmitting a statistical average value of the number of resources used by the first information in a third time period;
transmitting a statistical average of the number of bits used for the predetermined type of information in the first information during a fourth time period;
and transmitting the statistical average value of the resource quantity used by the information of the preset type in the first information in a fifth time period.
Specifically, the first time period may be a preset time period, such as 80ms, 20ms, 10ms, 5ms, and the like, 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 includes: (A/B). C, wherein A is a value in a statistical period, B is the time length of the statistical period, C is the length of the Xth time period, and B is greater than C. In particular, B is much larger than C. X is a first time period, a second time period, a third time period, a fourth time period or a fifth time period.
When the first information is SSB, the load parameter may be determined according to an actual number of transmitted SSBs in an SSB repetition period, or a statistical average of the number of transmitted SSBs in the first time period. The load parameter is used to determine a channel access capability corresponding to the first information, such as an energy detection threshold and/or a channel access priority used when the first information is transmitted.
When the first information is the first OSI, the load parameter can be determined according to a statistical average of the number of bits used by the first OSI in the second time period, or a statistical average of the number of resources used by the first OSI. The unit of the Resource quantity is a Resource Element (RE) or a Physical Resource Block (PRB).
When the load parameters are: when the statistical average value of the number of bits used for transmitting the predetermined type of information in the first information is transmitted in the fourth time period, it can be understood that the channel access capability of any member information (i.e. any one of the predetermined types of information) is determined according to the overall overhead of a typical broadcast channel (the predetermined type of information includes SSB, SIB1, at least one OSI), such as the overall number of transmission bits of all the predetermined types of information in the fourth time period, or the overall number of occupied resources of all the predetermined types of information in the fourth time period.
The predetermined types may include one or more of SSBs, SIB1, at least one OSI, and Paging messages. For example, the SIB1 may be included only, or SIB1 and at least one OSI, etc., and the SIB may also include SSB, SIB1, at least one OSI, and a paging message, which is not limited herein.
Further, the first frequency band may be an unlicensed frequency band, and/or the first frequency band employs a frame structure 3.
The 3GPP proposed the concept of long Term Evolution (L ong Term Evolution, L TE) assisted Access (L TE assisted Access, L AA) for using unlicensed spectrum with the help of L TE licensed spectrum, a new frame structure (frame structure 3) is used in L AA, which is used by the serving cell, in frame structure 3, all communication devices (such as base stations or terminals) need to perform a Channel Access Procedure before performing signal transmission.
When the network side equipment sends the first information on the unauthorized frequency band and a large number of devices using the unauthorized frequency band are used, the use conflict of the unauthorized frequency band can be caused, and the transmission performance of part of the network side equipment is reduced.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a network-side device according to an embodiment of the present invention, and as shown in fig. 4, the network-side device 200 includes: a determination module 201.
The determining module 201 is configured to determine, according to a mapping relationship between a load parameter of the first information and an access capability parameter, a value of the access capability parameter used when the first information is transmitted in the first frequency band.
Further, the first frequency band is an unlicensed frequency band, and/or the first frequency band adopts a frame structure 3.
Further, the mapping relation satisfies the following condition:

and/or in case the access capability parameter employed in the transmission of said first information comprises a channel access priority class,
for any 2 first load parameters and second load parameters, if the information load indicated by the first load parameters is greater than the information load indicated by the second load parameters, the channel access priority class adopted when the first information is transmitted is not less than the channel access priority class adopted when the second information is transmitted.
