Communication method, device and system

Technical Field

The present application relates to the field of communications, and in particular, to a communication method, apparatus, and system.

Background

With the rapid development of communication technology, the internet, i.e. the internet of things, connected with things has come into play. The Internet of things is an important component of a new generation of information technology and is also an important development stage of the information era. Information is usually acquired through deployed sensors in the internet of things, and then the sensors transmit electromagnetic waves to the space to exchange and communicate information.

Looking at future applications of the internet of things, a large number of sensors are deployed in some scenarios. The sensor actively transmits electromagnetic waves to communicate by means of the radio frequency module arranged in the sensor, the radio frequency module accounts for a certain proportion of the device cost, the power consumption of the radio frequency module also accounts for a certain proportion, the service life of the sensor battery is short, and a large amount of manpower and material resources are consumed for replacing the battery.

Due to the fact that cost, power consumption and size are basic requirements of the technology of the Internet of Things, the technology of narrowband Internet of Things (NB-IoT) with the characteristics of low power consumption, stable connection, low cost, excellent architecture optimization and the like is concerned. The NB-IOT uses the authorized frequency band, can adopt three deployment modes such as in-band, guard band or independent carrier, and coexists with the existing network. However, the radio frequency module of the NB-IOT user equipment is unavoidable, and economic mass deployment still cannot be achieved in view of cost and power consumption. In addition, the power consumption reduction of the current high-density energy storage (battery) and radio frequency devices is slow, and therefore, the radio frequency passive equipment without the radio frequency module is applied to the Internet of things and has obvious advantages.

The radio frequency passive device has no radio frequency module, so that the cost and the power consumption are greatly reduced, the service life of the battery is prolonged, the size of the battery is reduced, and the performance of the Internet of things is improved when the radio frequency passive device is applied to the Internet of things. The Internet of things using the radio frequency passive equipment can be applied to a plurality of fields. For example, in the field of agricultural irrigation, a radio frequency passive sensor can be deployed in soil to acquire soil humidity for scientific irrigation; in animal husbandry, a radio frequency passive sensor can be deployed on livestock to acquire vital sign information of the livestock and the like.

How to realize information exchange and communication of radio frequency passive equipment in a cellular communication network becomes a problem to be solved urgently at present.

As shown in fig. 5, the method may include:

s501, the network equipment sends first configuration information to a radio frequency signal sending source.

Wherein the first configuration information comprises a first resource configuration for the radio frequency signal transmission source to transmit the first communication signal.

It should be noted that, in practical applications, the network device may configure respective resource configurations for each communication signal or information transmitted by the radio frequency signal transmission source, and of course, the network device may also configure one resource configuration for the radio frequency signal transmission source to transmit all the communication signals and information, which is not specifically limited in this embodiment of the present application.

Optionally, the network device may generate the content of the first resource configuration before sending the first configuration information, or may determine the content of the first resource configuration in advance, which is not specifically limited in this embodiment of the application.

In one possible implementation, the network device may determine the content of the resource configuration according to the network condition.

In one possible implementation, different resource formats are pre-configured for indicating different usages of the communication signal, and the resource format of the first communication signal is configured in the first configuration information to indicate the usages of the first communication signal. For example, the resource format of the first communication signal may include a random access Message 1 (Message 1, msg 1) preamble resource.

It should be noted that the usage indication information may be multiplexed with other information in the first configuration information. For example, the access scheduling information is used as the usage indication information.

In another possible implementation, the radio frequency signal transmission source randomly generates the access scheduling information when generating the first communication signal.

S504, the user equipment receives the access scheduling information.

And S505, the user equipment determines whether to access the network according to the access scheduling information.

If the user equipment determines to access the network in S505, the user equipment modulates the access request information into the first communication signal to be reflected and transmitted when receiving the first communication signal; if the user equipment determines not to access the network in S505, the network is not accessed using the received first communication signal.

Specifically, in S505, the determining, by the ue, whether to access the network according to the access scheduling information may include: the user equipment performs preset operation on the ID and the access scheduling information, and if the result meets a preset condition, the user equipment determines to access the network; and if the result does not meet the preset condition, determining not to access the network.

It should be noted that, in practical application, the contents of the access scheduling information, the preset operation, and the preset condition may be configured according to actual requirements, which is not specifically limited in the embodiment of the present application.

Illustratively, the access scheduling information is an SFN system frame number, the preset operation is a remainder operation (mod), and the preset condition is that the preset condition is smaller than a preset threshold (X), that is, it is determined that the device ID mod SFN is smaller than X in S505.

The synchronization signal includes network synchronization information, which is used for the user equipment to perform network synchronization. Illustratively, the network synchronization may be downlink synchronization.

Optionally, the synchronization signal may include a wake-up signal, which is a specific sequence for waking up the user equipment.

In one possible implementation, where the synchronization signal does not include a wake-up signal, the radio frequency signal transmission source may transmit the wake-up signal prior to transmitting the synchronization signal.

In one possible implementation, the wake-up signal is transmitted at a higher power than the network device configured to transmit the communication signal.

And S507, the user equipment receives the synchronous signal.

The first communication signal is used for reflecting the access request information by the user equipment.

Specifically, the first resource configuration indicates the characteristics of the resource for transmitting the first communication signal, and in S503, the radio frequency signal transmission source may generate and transmit the communication signal according to the first resource configuration, which is not described in detail herein for the specific process of generating and transmitting the communication signal.

Optionally, the radio frequency signal transmission source may transmit the communication signal in a broadcast manner, a multicast manner, or a unicast manner, which is not specifically limited in this embodiment of the present application and will not be described one by one subsequently.

It should be noted that, in the present application, when the radio frequency signal transmission source transmits a communication signal or other information, the communication signal or other information is transmitted to the user equipment according to the resource configuration provided by the network device, and the subsequent contents are not described one by one.

All or part of the reflected and transmitted communication signals can be configured according to actual requirements, which is not specifically limited in the embodiments of the present application and will not be described one by one subsequently. For example, the user equipment may reflect only a portion of the transmitted communication signal modulated with the content to be transmitted, or may reflect the entire communication signal.

Specifically, the location of the resource where the user equipment reflects and transmits the modulated first communication signal is known by the network equipment, and therefore, the network equipment can receive the first communication signal modulated with the access request information at the corresponding location.

S513, the network device sends second configuration information to the radio frequency signal sending source, where the second configuration information includes an access request response.

The access request response is used for responding to access request information sent by the user equipment, and the content and the form of the access request response are not specifically limited in the embodiment of the application.

For example, the ue may determine whether the contention access is successful according to whether the access completion information includes its own identification information. Or, the ue may determine whether the contention access is successful according to whether the access completion information includes its own type. Or, the ue may determine whether the contention access is successful according to whether the access completion information includes the service type supported by the ue.

When the access completion information received by the ue in S520 indicates that the ue fails to compete, the ue may resend the access request information through a subsequent communication signal, which is not described herein again and is similar to the foregoing.

When a plurality of other pieces of information are transmitted in combination, they may be included in the control signal and transmitted.

Specifically, the purpose of the network device sending the fifth configuration information in S601 is to configure the radio frequency signal transmission source to send the fifth communication signal, so as to schedule at least one user equipment to transmit data, which may include, but is not limited to, the following two implementation schemes:

in implementation scheme 1, the network device provides, by using the fifth configuration information, the identification information of the at least one user equipment to be scheduled to the radio frequency signal transmission source, so that the radio frequency signal transmission source transmits the fifth communication signal to schedule the at least one user equipment.

In a possible implementation, corresponding to implementation scheme 1, the fifth resource configuration may further include: identification information of the scheduled at least one user equipment.

In a possible implementation, corresponding to implementation scheme 1, the communication method provided in the embodiment of the present application may further include: the network device transmits identification information of the scheduled at least one user equipment to the radio frequency signal transmission source. The identification information of at least one scheduled user equipment, which is sent by the network device to the radio frequency signal sending source, may be sent alone, or may be sent together with other information, which is not specifically limited in this embodiment of the application.

Optionally, the identification information of the scheduled at least one user equipment may include any one of the following information: an ID of the scheduled at least one user equipment, a cell-level identification of the scheduled at least one user equipment, an identification of an excitation source corresponding to the scheduled at least one user equipment, and an identification of a packet to which the scheduled at least one user equipment belongs.

The cell-level identifier of the ue may be a unique identifier allocated by the network device when the ue initially accesses the network.

The identifier of the excitation source corresponding to the user equipment refers to an identifier of an excitation source for the user equipment to receive the communication signal, and one identifier of the excitation source corresponds to at least one user equipment.

The identifier of the group to which the user equipment belongs is used to indicate a group of user equipment, and the user equipment belonging to the same group may have the same type, or support the same service type, or have other characteristics.

In implementation scheme 2, before the network device sends the fifth configuration information, at least one user equipment that needs to be scheduled is configured to be in a state to be scheduled, the radio frequency signal sending source is configured to send the fifth communication signal through the fifth configuration information, and when the fifth communication signal is received, the at least one user equipment that needs to be scheduled is configured to implement scheduling.

The to-be-scheduled state refers to a state in which the ue has received the information or signal of the control class and is waiting for the communication signal indicated by the received information or signal of the control class.

It should be noted that, in implementation scheme 2, for a specific scheme and implementation that the network device configures at least one user equipment that needs to be scheduled before sending the fifth configuration information, the embodiment of the present application is not specifically limited. For example, before sending the fifth configuration information, the network device may send a special control signaling through the radio frequency signal sending source, so as to configure the scheduled user equipment to be in a to-be-scheduled state.

S602, the radio frequency signal transmission source receives fifth configuration information from the network device.

Wherein the fifth configuration information includes a fifth resource configuration.

In one possible implementation, corresponding to implementation 1 in S601, the fifth configuration information further includes identification information of at least one scheduled user equipment.

In a possible implementation, corresponding to implementation scheme 2 in S601, the communication method provided in the embodiment of the present application may further include: the radio frequency signal transmission source receives identification information of at least one scheduled user equipment from the network device.

S603, the radio frequency signal transmission source transmits a fifth communication signal according to the fifth resource configuration.

Wherein the fifth communication signal is used for scheduling the scheduled at least one user equipment.

Specifically, for sending the communication signal in S603, reference may be made to related implementation in the communication method illustrated in fig. 5, and details are not repeated here.

Corresponding to two implementation schemes in S601, the fifth communication signal is used for scheduling at least one scheduled user equipment, and specifically includes the following two implementations:

implementation a, corresponding to implementation 1 in S601, the fifth communication signal includes identification information of the scheduled at least one user equipment for scheduling the scheduled at least one user equipment.

Implementation B, corresponding to implementation 2 in S601, after the fifth communication signal is sent, at least one user equipment that receives the fifth communication signal and is in a state to be scheduled is scheduled.

In a possible implementation, the communication method provided in the embodiment of the present application may further include: the radio frequency signal transmission source transmits a resource location indication indicating a location of a transmission resource of the fifth communication signal. And the transmission resource of the fifth communication signal is used for the scheduled user equipment to transmit the data to be transmitted.

The transmission resource included in the communication signal may be an idle resource in the communication signal or a resource for transmitting data specified by a protocol, and the specific location of the transmission resource in the communication signal is not limited in the present application.

In a possible implementation, the communication method provided in the embodiment of the present application may further include: the size of the transmission resource for the radio frequency signal transmission source to transmit the fifth communication signal.

S604, the user equipment receives a fifth communication signal from the radio frequency signal transmission source.

It should be noted that, the fifth communication signal has already been described in detail in S603, and is not described herein again.

It should be further noted that the process of executing the requested communication method by each of the scheduled at least one ue is the same, and this document only describes from the perspective of one ue, and the others are not described in detail. The user equipment refers to any one of the at least one scheduled user equipment.

S605, the user equipment confirms that it is scheduled.

Corresponding to the two implementation schemes in S601, the user equipment in S605 confirms that it is scheduled, which includes the following two cases:

in case one, corresponding to implementation 1 in S601, the ue determines whether it is scheduled according to the identification information of the ue included in the fifth communication signal. And if the fifth communication signal comprises the identification information corresponding to the user equipment, the user equipment is scheduled.

In case two, corresponding to implementation 2 in S601, if the ue has been configured to be in the to-be-scheduled state and receives the fifth communication signal, it is determined that the ue is scheduled.

After the ue confirms that it is scheduled in S605, S606 is performed, otherwise, it continues to wait for scheduling.

S606, the user equipment modulates the data to be transmitted into the transmission resource of the fifth communication signal, and transmits the modulated fifth communication signal in a whole or partial reflection mode.

The data to be sent refers to data transmitted from the user equipment to the network equipment, and the content and the form of the data to be sent are not specifically limited in the embodiment of the present application. When the types of the user equipment are different, the types of the data to be transmitted are different.

For example, when the user equipment is a sensor in the internet of things, the data to be sent may be information collected by the sensor.

Specifically, the processes of modulation and reflection transmission in S606 may refer to related implementations in the communication method illustrated in fig. 5, and are not described here again.

If the size of the transmission resource of the fifth communication signal is smaller than the size of the data to be transmitted, it is determined that additional resources need to be requested, otherwise, additional resources do not need to be requested.

In a possible implementation, when the user equipment further receives the size of the transmission resource of the fifth communication signal, before S606, the communication method provided in this embodiment of the present application may further include: and the user equipment judges whether additional resources need to be requested or not according to the size of the transmission resources of the fifth communication signal and the size of the data to be transmitted, and modulates the resource request indication into the transmission resources of the fifth communication signal when judging that the additional resources need to be requested.

In one possible implementation, the resource request indication is for requesting a fixed resource, and the resource request indication is fixed content.

In another possible implementation, the resource request indicator is assigned a different value, corresponding to requesting resources of different sizes.

In a possible implementation, the user equipment determines that additional resources need to be requested according to the size of the transmission resource of the fifth communication signal and the size of the data to be transmitted, modulates the resource request indication into the transmission resource of the fifth communication signal, and waits for the network equipment to allocate the additional resources and then transmit the data to be transmitted.

In a possible implementation, the user equipment determines that additional resources need to be requested according to the size of the transmission resource of the fifth communication signal and the size of the data to be transmitted, modulates a resource request indication into the transmission resource of the fifth communication signal, and waits for the network equipment to allocate the additional resources in the transmission resource of part of the fifth communication signal of the data to be transmitted and then transmits the rest of the data to be transmitted.

In a possible implementation, the ue may determine whether to transmit a part of the data to be transmitted when the resource request indication is transmitted according to whether a difference between the size of the fifth communication signal transmission resource and the size of the data to be transmitted is greater than a preset threshold.

For example, if the difference between the size of the transmission resource according to the fifth communication signal and the size of the data to be transmitted is greater than the preset threshold, the user equipment transmits part of the data to be transmitted when the transmission resource request indicates. This is by way of example only and not intended to be limiting.

S607, the network device receives, from the user equipment, the communication signal modulated with the data to be transmitted and/or the resource request indication.

When only the data to be transmitted is modulated in the communication signal received by the network equipment, the transmission of the data to be transmitted is completed. When the communication signal received by the network device modulates the resource request indication, the network device needs to allocate additional resources for the user equipment to transmit the data to be transmitted.

And S609, the network equipment sends sixth configuration information to the radio frequency signal sending source.

The sixth configuration information includes a retransmission instruction, or the sixth configuration information includes a retransmission instruction and a sixth resource configuration for sending the retransmission instruction. The retransmission indication is used to request the user equipment to retransmit all or part of the pending data.

It should be noted that the content of the retransmission instruction and the data to be retransmitted corresponding to the content may be specified by a protocol, or may be embodied by a preset corresponding relationship, which is not specifically limited in this embodiment of the application.

S610, the radio frequency signal transmission source receives sixth configuration information from the network device.

S611, the radio frequency signal transmission source sends a retransmission instruction and a sixth communication signal according to the configuration of the network device.

And the sixth communication signal is used for the user equipment to modulate and retransmit all or part of the data to be transmitted corresponding to the indication.

Specifically, S611 may be specifically implemented as: and the radio frequency signal sending source sends a retransmission instruction according to the sixth resource configuration, and sends a sixth communication signal according to the seventh resource configuration.

In a possible implementation, the fifth configuration information includes a sixth resource configuration and/or a seventh resource configuration.

In another possible implementation, the sixth resource is configured as a fifth resource configuration, and the seventh resource is configured as a fifth resource configuration.

In another possible implementation, the sixth configuration information includes a sixth resource configuration and/or a seventh resource configuration.

In another possible implementation, the sixth resource configuration and the seventh resource configuration may be the same or different.

S613, the user equipment modulates the data to be transmitted of the retransmission indication request onto a transmission resource of the sixth communication signal, and reflects all or part of the modulated sixth communication signal to transmit.

Specifically, the processes of modulation and reflection transmission in S613 may refer to related implementations in the communication method illustrated in fig. 5, and are not described here again.

After S613, jump to S607 is made until the transmission of the data to be transmitted is completed.
