Detailed Description

The application discloses a communication method, a communication device, communication equipment and a storage medium, which are used for improving the reliability of the transmission of channel state information of a broadband channel and link data of user equipment.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 application.

Referring to fig. 2, fig. 2 is a flow chart of a communication method disclosed in the present application. The communication method is executed by a broadband cluster base station in the broadband-narrowband fusion system. The communication method comprises the following steps:

step S201: and judging whether a preset condition is met.

Step S202: and if the preset condition is met, taking the broadband channel allocated to the user equipment as a target channel.

Step S203: and if the preset condition is not met, the narrow-band channel allocated to the user equipment is taken as a target channel.

The user equipment in the wide-narrow band fusion system is a multi-mode terminal, the user equipment is provided with a wide-band receiving interface and a narrow-band receiving interface, and a wide-band channel and a narrow-band channel are distributed for the user equipment. The channel quality of the broadband channel may be affected by various factors, and when the channel quality of the broadband channel is low, the process of transmitting data to the broadband cluster base station by the user equipment through the broadband channel may be unreliable, for example, data transmission delay or data transmission failure occurs.

The wideband trunking base station needs to determine corresponding Modulation and Coding parameters according to CSI (Channel State Information) of a wideband Channel, where the Modulation and Coding parameters include MCS (Modulation and Coding Scheme) and Coding rate. The Channel state information includes CQI (Channel Quality Indicator) and RI (Rank Indication).

The broadband cluster base station has higher requirement on the real-time performance of the channel state information.

In the prior art, the user equipment fixedly sends the channel state information of the broadband channel to the broadband cluster base station through the broadband channel, and if the channel quality of the broadband channel is poor, the transmission of the channel state information of the broadband channel is unreliable.

In this application, the user equipment may feed back the channel state information of the wideband channel to the wideband cluster base station through the wideband channel, and may also feed back the channel state information of the wideband channel to the wideband cluster base station through another manner. Further, whether the broadband channel is used as the target channel or the narrowband channel is used as the target channel is determined by judging whether the preset condition is met.

In practice, the preset condition is at least used for indicating that: whether the channel quality of the wideband channel allocated to the user equipment meets the preset requirement. That is, the channel quality of the wideband channel allocated to the user equipment is taken as a basis for selecting a target channel among the wideband channel and the narrowband channel.

In addition, the current uplink service of the user equipment can be used as another basis for selecting the target channel from the broadband channel and the narrowband channel. That is, the preset condition is used to indicate that: and whether the channel quality of the broadband channel allocated to the user equipment and the current uplink service of the user equipment meet preset requirements or not.

Step S204: sending a reconfiguration message to the user equipment. The reconfiguration message carries an identifier of a target channel, so that when the target channel is a narrowband channel, the user equipment sends channel state information of a wideband channel to a narrowband cluster base station in the wideband-narrowband fusion system through the narrowband channel, and the narrowband cluster base station sends the channel state information to the wideband cluster base station, so that when the target channel is a wideband channel, the user equipment sends the channel state information of the wideband channel to the wideband cluster base station through the wideband channel.

The reconfiguration message sent by the broadband cluster base station to the user equipment carries the identifier of the target channel. And the user equipment receives the reconfiguration message and extracts the identification of the target channel carried by the reconfiguration message. And if the target channel is determined to be the broadband channel according to the identification, the user equipment sends the channel state information of the broadband channel to the broadband cluster base station through the broadband channel. If the target channel is determined to be the narrowband channel according to the identifier, the user equipment sends the channel state information of the wideband channel to the narrowband cluster base station through the narrowband channel, and the narrowband cluster base station sends the channel state information of the wideband channel to the wideband cluster base station.

It can be understood that, when the user equipment sends the channel state information of the wideband channel to the narrowband cluster base station through the narrowband channel, the channel state information of the wideband channel needs to be marked, so that the narrowband cluster base station sends the channel state information of the wideband channel to the wideband cluster base station after receiving the channel state information of the wideband channel.

For example, the message sent by the user equipment to the narrowband trunking base station contains channel state information of the wideband channel and an identification of the wideband trunking base station.

That is, in the present application, when the preset condition is satisfied, the broadband trunking base station instructs the user equipment to feed back the channel state information of the broadband channel through the broadband channel. When the preset condition is not met, the broadband cluster base station instructs the user equipment to feed back the channel state information of the broadband channel to the narrowband cluster base station through the narrowband channel, the broadband cluster base station and the narrowband cluster base station in the broadband-narrowband fusion system are interconnected through a wire, and the narrowband cluster base station sends the channel state information of the broadband channel to the broadband cluster base station after receiving the channel state information of the broadband channel. Compared with the prior art that the user equipment fixedly feeds back the channel state information of the broadband channel to the broadband cluster base station through the broadband channel, the scheme can improve the transmission reliability of the channel state information of the broadband channel.

The narrow-band cluster communication system has the characteristics of large-area coverage, reliable and stable transmission and low power consumption. When the preset condition is not met, the user equipment feeds back the channel state information of the broadband channel to the narrowband cluster base station through the narrowband system distributed to the user equipment, and the narrowband cluster base station sends the channel state information of the broadband channel to the broadband cluster base station, so that the reliability of data transmission can be ensured, and the narrowband cluster communication system has the advantage of low power consumption, so that the power consumption of the user equipment can be reduced.

The communication method applied to the broadband cluster base station comprises the steps of judging whether preset conditions are met or not, if the preset conditions are met, using a broadband channel distributed for user equipment as a target channel, otherwise, using a narrowband channel distributed for the user equipment as the target channel, and then sending a reconfiguration message carrying an identifier of the target channel to the user equipment, so that the user equipment sends channel state information of the broadband channel to the narrowband cluster base station through the narrowband channel when the target channel is the narrowband channel, and the narrowband cluster base station sends the channel state information to the broadband cluster base station, so that the user equipment sends the channel state information of the broadband channel to the broadband cluster base station through the broadband channel when the target channel is the broadband channel. In the scheme, the broadband cluster base station instructs the user equipment to feed back the channel state information of the broadband channel to the broadband cluster base station through the broadband channel or through the narrowband channel through the reconfiguration message, and compared with the prior art that the user equipment fixedly feeds back the channel state information of the broadband channel to the broadband cluster base station through the broadband channel, the transmission reliability of the channel state information can be improved, and the narrowband cluster communication has the characteristic of low power consumption, so that when the user equipment feeds back the channel state information of the broadband channel through the narrowband channel, the power consumption of the user equipment can be reduced. In addition, in the process that the user equipment executes the uplink broadband service through the broadband channel, the channel state information of the broadband channel is fed back through the narrowband channel, and therefore the occupation of the bandwidth resources of the broadband channel can be reduced.

In an embodiment of the present application, determining whether a preset condition is satisfied includes:

judging whether the channel quality of a broadband channel allocated to user equipment meets a first preset requirement or not;

and if the channel quality of the broadband channel distributed for the user equipment meets the first preset requirement, determining that the preset condition is met, otherwise, determining that the preset condition is not met.

In another embodiment of the present application, the determining whether the preset condition is satisfied includes:

and if the channel quality of the broadband channel distributed to the user equipment meets the first preset requirement and the current uplink service of the user equipment meets the second preset requirement, determining that the preset condition is met, otherwise, determining that the preset condition is not met.

The location of the user equipment in the cell of the broadband cluster base station may have an impact on the channel quality of the broadband channel of the user equipment. For example, when the user equipment is located at the cell edge of the broadband trunking base station, the uplink power is limited, and the channel quality of the broadband channel is poor. Therefore, the location of the user equipment in the cell of the broadband cluster base station can be taken as one element for determining the channel quality of the broadband channel allocated for the user equipment.

In addition, the moving speed of the user equipment may have an influence on the channel quality of the wideband channel. For example, when the user equipment is in a high-speed moving state, the channel quality of the wideband channel is poor. Therefore, the mobility state of the user equipment can be taken as another element for determining the channel quality of the wideband channel allocated to the user equipment.

In an implementation, the channel quality of the wideband channel allocated to the user equipment may be determined based on the location of the user equipment in the cell of the wideband cluster base station and/or the mobility state of the user equipment.

In a possible implementation manner, the determining whether the channel quality of the wideband channel allocated to the user equipment meets a first preset requirement includes:

determining whether the user equipment is located at the cell edge of the broadband cluster base station;

determining whether the user equipment is in a high-speed moving state;

In a possible implementation manner, the determining whether the current uplink service of the user equipment meets the second preset requirement includes:

determining the type of the current uplink service of the user equipment;

and if the current uplink service of the user equipment is the broadband uplink service, determining that the current uplink service of the user equipment meets a second preset requirement, otherwise, determining that the current uplink service of the user equipment does not meet the second preset requirement.

determining the type of the current uplink service of the user equipment;

if the current uplink service of the user equipment is the broadband uplink service and the uplink service load reaches a preset load threshold, determining that the current uplink service of the user equipment does not meet a second preset requirement;

and if the current uplink service of the user equipment is the broadband uplink service and the uplink service load is lower than the preset load threshold, determining that the current uplink service of the user equipment meets a second preset requirement.

That is, if the user equipment does not currently execute the broadband uplink service, it is determined that the second preset requirement is not satisfied, if the user equipment currently executes the broadband uplink service, the uplink service load is further determined, if the uplink service load reaches a preset load threshold (i.e., is equal to or higher than the preset load threshold), it is determined that the second preset requirement is not satisfied, and if the uplink service load is lower than the preset load threshold, it is determined that the second preset requirement is satisfied.

It can be understood that, compared with the broadband trunking communication, the narrowband trunking communication has lower power consumption, and therefore, if the user equipment does not execute the broadband uplink service, it is determined that the current uplink service of the user equipment does not meet the second preset requirement, and accordingly, the narrowband channel is taken as the target channel, which can reduce the power consumption generated by the user equipment feeding back the channel state information of the broadband channel to the broadband trunking base station. If the current uplink service of the user equipment is the broadband uplink service but the uplink service load reaches the preset load threshold, determining that the current uplink service of the user equipment does not meet the second preset requirement, and correspondingly, taking the narrowband channel as the target channel, the occupation of bandwidth resources of the broadband channel can be reduced, thereby providing better data support for the high-speed data service. And if the current uplink service of the user equipment is the broadband uplink service and the uplink service load is lower than the preset load threshold, determining that the current uplink service of the user equipment meets a second preset requirement, combining the second preset requirement with the channel quality of a broadband channel allocated to the user equipment, and determining a target channel in the broadband channel and the narrowband channel.

Referring to fig. 3, fig. 3 is a flowchart of another communication method disclosed in the present application. The communication method is executed by a broadband cluster base station in the broadband-narrowband fusion system. The communication method comprises the following steps:

step S301: and judging whether the user equipment is positioned at the cell edge of the broadband cluster base station, if so, executing step S305, otherwise, executing step S302.

In implementation, whether the user equipment is located at the cell edge of the broadband cluster base station may be determined in various ways. For example, the user equipment measures RSRP (Reference Signal Receiving Power), determines that the user equipment is located at a cell edge of the wideband cluster base station if the measured RSRP is less than a preset threshold, and determines that the user equipment is not located at the cell edge of the wideband cluster base station if the measured RSRP is greater than or equal to the preset threshold.

Step S302: and judging whether the user equipment is executing the broadband uplink service, if so, executing the step S303, otherwise, executing the step S305.

Step S303: and judging whether the user equipment is executing the broadband uplink service and the uplink service load reaches a preset load threshold, if so, executing the step S305, otherwise, executing the step S304.

Step S304: and judging whether the user equipment is in a high-speed moving state, if so, executing step S305, otherwise, executing step S306.

Judging whether the user equipment is in the high-speed moving state means: and judging whether the moving speed of the user equipment reaches a preset speed threshold value. The speed threshold is an empirical value, for example, the speed threshold may be configured to be 120 km/h, although this is only one example of the speed threshold.

In practice, whether the user equipment is in the high-speed moving state can be judged in various ways. For example, the user equipment measures the moving speed according to the frequency offset.

Step S305: step S307 is performed with the narrowband channel allocated to the user equipment as the target channel.

Step S306: step S307 is performed with the wideband channel allocated to the user equipment as the target channel.

Step S307: and sending a reconfiguration message to the user equipment, wherein the reconfiguration message carries the identifier of the target channel, so that the user equipment sends the channel state information of the broadband channel to the narrowband cluster base station through the narrowband channel when the target channel is the narrowband channel, and sends the channel state information to the broadband cluster base station through the narrowband cluster base station, so that the user equipment sends the channel state information of the broadband channel to the broadband cluster base station through the broadband channel when the target channel is the broadband channel.

The communication method applied to the wideband cluster base station shown in fig. 3 of the present application determines a target channel in a wideband channel and a narrowband channel allocated to a user based on multiple dimensions, and if at least one of that a user equipment does not execute a wideband uplink service, that the user equipment is executing the wideband uplink service and the uplink service load reaches a preset load threshold, that the user equipment is located at a cell edge of the wideband cluster base station, and that the user equipment is in a high-speed moving state is satisfied, the narrowband channel allocated to the user equipment is taken as the target channel, so that the user equipment sends channel state information of the wideband channel to the narrowband cluster base station through the narrowband channel, and sends channel state information to the wideband cluster base station through the narrowband cluster base station, and if the user equipment is executing the wideband uplink service and the uplink service load is lower than the preset load threshold, the user equipment is located at a non-cell edge of the wideband cluster base station, and if the user equipment is not in the high-speed moving state, the broadband channel is taken as a target channel, so that the user equipment sends the channel state information of the broadband channel to the broadband cluster base station through the broadband channel. Based on the communication method shown in fig. 3, on the basis of ensuring the transmission reliability of the channel state information, the power consumption of the user equipment can be reduced, and the occupation of the bandwidth resources of the broadband channel is reduced, so as to better support the high-speed data service.

Referring to fig. 4, fig. 4 is a flowchart of another communication method disclosed in the present application. The communication method is executed by the user equipment in the broadband and narrowband convergence system. The communication method comprises the following steps:

step S401: and judging whether a preset condition is met.

User equipment in the broadband-narrowband fusion system needs to actively send own link data to the broadband cluster base station. The link data includes PH (Power Headroom) and MAC CE (MAC Control Element).

Step S402: and if the preset conditions are met, transmitting the link data of the user equipment to the broadband cluster base station through the broadband channel distributed to the user equipment.

Step S403: and if the preset condition is not met, sending the link data of the user equipment to the narrow-band cluster base station through the narrow-band channel distributed for the user equipment, and sending the link data to the broadband cluster base station by the narrow-band cluster base station.

The channel quality of the broadband channel may be affected by various factors, and if the channel quality of the broadband channel is poor, the process of transmitting data to the broadband cluster base station by the user equipment through the broadband channel may be unreliable, for example, data transmission delay or data transmission failure may occur.

In the prior art, the user equipment fixedly sends link data to the broadband trunking base station through the broadband channel, and if the channel quality of the broadband channel is poor, the transmission of the link data is unreliable.

In this application, the user equipment may feed back link data to the broadband trunking base station through another way, in addition to feeding back link data to the broadband trunking base station through the broadband channel, specifically, the user equipment sends the link data to the narrowband trunking base station through the narrowband channel, and then the narrowband trunking base station sends the link data to the broadband trunking base station. Further, the user equipment determines which mode to feed back link data to the broadband cluster base station by judging whether a preset condition is met. Compared with the prior art that the user equipment fixedly feeds the link data back to the broadband cluster base station through the broadband channel, the method can improve the transmission reliability of the link data.

In practice, the preset condition is at least used for indicating that: whether the channel quality of the wideband channel allocated to the user equipment meets the preset requirement. That is, the channel quality of the wideband channel allocated for the user equipment is taken as a basis for determining in which way to feed back link data to the wideband cluster base station.

In addition, the current uplink service of the user equipment can be used as another basis for determining the mode for feeding back the link data to the broadband cluster base station. That is, the preset condition is used to indicate that: and whether the channel quality of the broadband channel allocated to the user equipment and the current uplink service of the user equipment meet preset requirements or not.

It can be understood that, when the user equipment sends link data to the narrowband trunking base station through the narrowband channel, the link data needs to be marked, so that the narrowband trunking base station sends the link data of the user equipment to the broadband trunking base station after receiving the link data of the user equipment.

For example, the message sent by the user equipment to the narrowband clustered base station contains the link data and the identification of the wideband clustered base station.

In an embodiment of the present application, on the basis of the communication method shown in fig. 4 of the present application, the method further includes:

receiving a reconfiguration message sent by a broadband cluster base station, wherein the reconfiguration message carries an identifier of a target channel;

when the target channel is a narrow-band channel, sending channel state information of a wide-band channel to a narrow-band cluster base station through the narrow-band channel, and sending the channel state information to the wide-band cluster base station by the narrow-band cluster base station;

and when the target channel is a broadband channel, sending the channel state information of the broadband channel to the broadband cluster base station through the broadband channel.

The broadband cluster base station determines a broadband channel allocated to the user equipment as a target channel under the condition that the preset condition is met, determines a narrowband channel allocated to the user equipment as the target channel under the condition that the preset condition is not met, and sends a reconfiguration message carrying an identifier of the target channel to the user equipment. And the user equipment receives the reconfiguration message sent by the broadband trunking base station, and realizes the feedback of the channel state information of the broadband channel to the broadband trunking base station through the target channel indicated by the reconfiguration message.

determining whether the user equipment is in a high-speed moving state;

determining the type of the current uplink service of the user equipment;

It can be understood that, compared with the broadband trunking communication, the narrowband trunking communication has lower power consumption, and therefore, if the user equipment does not execute the broadband uplink service, it is determined that the current uplink service of the user equipment does not meet the second preset requirement, and accordingly, the user equipment sends link data to the narrowband trunking base station through the narrowband channel, and the narrowband trunking base station sends the link data to the broadband trunking base station, so that power consumption generated by the user equipment feeding the link data back to the broadband trunking base station can be reduced. If the current uplink service of the user equipment is the broadband uplink service, but the uplink service load reaches the preset load threshold, the current uplink service of the user equipment is determined not to meet the second preset requirement, correspondingly, the user equipment sends link data to the narrowband cluster base station through the narrowband channel, and the narrowband cluster base station sends the link data to the broadband cluster base station, so that the occupation of bandwidth resources of the broadband channel can be reduced, and better data support is provided for the high-speed data service. And if the current uplink service of the user equipment is the broadband uplink service and the uplink service load is lower than the preset load threshold, determining that the current uplink service of the user equipment meets a second preset requirement, combining the second preset requirement with the channel quality of a broadband channel distributed by the user equipment, and determining which way to feed back link data to the broadband cluster base station.

Step S504: and judging whether the user equipment is in a high-speed moving state, if so, executing step S505, otherwise, executing step S506.

Step S506: and transmitting the link data to the broadband trunking base station through the broadband channel.

The communication method applied to the user equipment shown in fig. 5 of the present application determines in which way to feed back link data to the broadband cluster base station based on multiple dimensions, if at least one of that the user equipment does not execute the broadband uplink service, that the user equipment is executing the broadband uplink service and the uplink service load reaches a preset load threshold value, that the user equipment is located at the cell edge of the broadband cluster base station, and that the user equipment is in a high-speed moving state is satisfied, the link data is transmitted to the narrowband cluster base station through the narrowband channel and transmitted by the narrowband cluster base station to the wideband cluster base station, if the user equipment is executing the broadband uplink service and the uplink service load is lower than the preset load threshold, the user equipment is located at the non-cell edge of the broadband cluster base station, and the user equipment is not in a high-speed moving state, the link data is sent to the broadband cluster base station through the broadband channel. Based on the communication method shown in fig. 5, on the basis of ensuring the transmission reliability of link data, the power consumption of the user equipment can be reduced, and the occupation of bandwidth resources of a broadband channel is reduced, so as to better support a high-speed data service.
