Description

Authorization-free resource access method, scheduling method and device, storage medium, terminal and base station

Technical Field

The invention relates to the technical field of communication, in particular to an authorization-free resource access method, a scheduling device, a storage medium, a terminal and a base station.

Background

With the development of communication technology and the increasing requirements of users on communication quality, New Radio (NR) technology will further consider application scenarios such as Enhanced Mobile BroadBand (eMBB), Ultra-reliable and Low Latency Communications (URLLC), and Massive machine type Communications (mtc).

Taking the URLLC as an example, the key technology is to achieve two conflicting requirements, where it is required to reduce the communication delay between the User Equipment (UE) and the network and to obtain higher reliability. One solution currently envisaged is to satisfy both of the above requirements simultaneously by means of an unauthorized access. It is noted that the unlicensed transmission is not limited to URLLC services.

The URLLC is further specified at the latest 3GPP RAN1#87 conference. For example, the protocol specifies that, in order to implement said URLLC, the network and the user equipment need to be able to support at least one unlicensed uplink transmission scheme; as another example, the protocol also provides that an unlicensed resource may be dedicated to one user device or may be shared by multiple user devices.

However, the prior art, including the latest conferences, does not specify how the unlicensed access should be made on the URLLC. One approach, which is discussed primarily at present, is to pre-define a hopping mechanism, based on which the ue can transmit uplink on contention-based uplink resources; another scheme is to pre-configure an uplink grant, for example, pre-configure the uplink grant for the ue, so that the ue can directly use the uplink grant when there is uplink data to be transmitted.

However, the above solutions are all invariable solutions (for example, parameters predefined or preconfigured based on the above solutions cannot be changed once being determined), and in practical applications, connection states, signaling transmission states, and the like between the ue and the network are all constantly changing, which makes the existing solutions not well applicable to practical applications, and is more likely to have a serious impact on access speed and access quality when the ue accesses the unlicensed resources, thereby resulting in meaningless scheduling (signaling) overhead and resource waste.

In summary, in the present phase, in most cases, the resource access mechanism between the ue and the network cannot meet the delay and reliability requirements that the URLLC needs to meet, and thus cannot enjoy the advantages of eliminating the scheduling (signaling) overhead and simplifying the access process due to the unlicensed access.

Detailed Description

As background, Ultra-reliable and Low Latency Communications (URLLC) is one representative of new generation wireless communication technologies, and has strict Latency and reliability requirements, in practical applications, the Latency imposed by scheduling may be prohibited by devices employing URLLC. Similarly, Machine Type Communication (MTC) is expected to include a large amount of devices that use short and infrequent messages for communication, and if the existing Long Term Evolution (LTE) technology is still used to implement the MTC, it will inevitably result in a large scheduling overhead.

Therefore, New Radio (NR) technology allows the ue to access the network resources in an access-free manner, so as to meet the low-latency data transmission requirements of URLLC and MTC. The resource may be a resource dedicated for the user equipment to perform the unauthorized access, or may be a resource in a general sense (for example, the resource may be used for the user equipment to perform the unauthorized access, or may be used for the user equipment to access after obtaining the authorization of the network). For convenience of description, such resources are collectively referred to as unlicensed resources in the embodiments of the present invention. In particular, the unlicensed access may eliminate scheduling (or signaling) overhead and may also simplify the access procedure of the user equipment.

The current mechanism of unauthorized resource access requires the network side and the user equipment to agree in advance. For example, a hopping scheme may be predefined by the network, based on which the user equipment uses the contended uplink resources for data transmission; or, the network may also pre-configure an uplink grant for the user equipment, and when the user equipment has uplink data to upload, the network resource to which the user equipment points may be directly accessed according to the uplink grant.

The above scheme can allow the user equipment to have unauthorized access to the unauthorized resources of the network to a certain extent. However, these existing solutions are invariable solutions, and the predefined or preconfigured parameters for the unlicensed access cannot be changed once determined. In practical application, the connection state and signaling transmission state between the ue and the network are constantly changing, which makes the existing solution not well adapted to practical application.

For example, since the URLLC allows one unlicensed resource of the network to be shared by multiple user equipments, the network may direct uplink grants preconfigured to the multiple user equipments to the same unlicensed resource, and when the multiple user equipments simultaneously use the unlicensed resource to transmit uplink data based on their respective uplink grants, the multiple user equipments will affect each other, which reduces the channel access speed and affects the uplink data transmission speed of the user equipments more. Further, based on the existing solution, even when other unlicensed resources of the network are in an idle state, the multiple user equipments allocated to the same unlicensed resource cannot use the idle unlicensed resources instead, which may have a serious impact on the access speed and the access quality when the user equipments access the unlicensed resources, and further cause meaningless scheduling (e.g. signaling) overhead and resource waste.

The inventor of the present application has analyzed that this is caused by the fact that the existing schemes do not allow the network to flexibly configure (or allocate) the unlicensed resources according to the communication status with the user equipment.

In order to solve the technical problem, on a user equipment side, the user equipment receives authorization-free resource information sent by a network, wherein the authorization-free resource information comprises indication information at least used for positioning authorization-free resources of the network, and the authorization-free resources comprise a plurality of minislots; sending an authorization-exempt request to the network; and accessing a target mini-slot in the authorization-free resource according to the authorization-free resource information and configuration response information, wherein the configuration response information is sent out by the network in response to the authorization-free request and is directed to the target mini-slot.

Those skilled in the art understand that, the technical solution of the embodiment of the present invention provides a variable authorization-free resource access scheme, where a user equipment with an authorization-free resource access requirement can access a target mini-slot according to the authorization-free resource information and configuration response information, where the target mini-slot may be allocated by the network after receiving an authorization-free request sent by the user equipment; the network may indicate the allocated target mini-slot to the user equipment through the fed back configuration response information. Furthermore, the technical scheme of the embodiment of the invention can better meet the requirements of low time delay and high reliability of communication technologies such as URLLC, MTC and the like, improve the channel access speed, reduce the signaling overhead and provide better communication experience for the user equipment adopting the technical scheme of the embodiment of the invention.

Further, on the network side, the network sends the information of the unlicensed resources, where the information of the unlicensed resources includes indication information at least used for locating the unlicensed resources of the network, and the unlicensed resources include a plurality of mini-slots; receiving an authorization-free request sent by user equipment; and responding to the authorization-free request, and sending configuration response information to the user equipment, wherein the configuration response information points to a target mini-slot in the authorization-free resource, so that the user equipment accesses the target mini-slot according to the authorization-free resource information and the configuration response information. Those skilled in the art understand that the technical solution of the embodiment of the present invention allows the network to allocate mini slots more flexibly, so as to better meet the requirement of unauthorized access of different user equipments, effectively eliminate the scheduling overhead, and simplify the access process of the user equipment.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 1 is a flowchart of an unauthorized resource access method according to a first embodiment of the present invention. The unauthorized resource may be a resource that is specifically configured for the user equipment to perform unauthorized access in a resource of the network; the present embodiment may be a process for describing, from the user equipment side, an unauthorized resource accessing to the network. It should be noted that the technical solution of the embodiment of the present invention can also be applied to a Semi-Persistent Scheduling (SRS) uplink resource access scenario.

Specifically, in this embodiment, the method for accessing unauthorized resources may be implemented according to the following steps:

step S101, receiving authorization-free resource information sent by a network, wherein the authorization-free resource information includes indication information at least used for positioning authorization-free resources of the network, and the authorization-free resources include a plurality of minislots.

Step S102, sending an authorization-free request to the network.

Step S103, accessing a target mini-slot in the authorization-free resource according to the authorization-free resource information and configuration response information, wherein the configuration response information is sent by the network in response to the authorization-free request and is directed to the target mini-slot.

More specifically, taking URLLC as an example, the grant-free resource allocated to URLLC may be repeated every preset time unit in time sequence, that is, the grant-free resource is repeated periodically, and the user equipment may access the resource without grant in the period. Still further, the preset time unit may be indicated by a periodic parameter included in the unlicensed resource parameter set. Preferably, the unlicensed Resource information may be received through a Radio Resource Control (RRC) message (RRC message, which may also be referred to as RRC signaling).

Referring to fig. 2, a plurality of time domain units may be divided in a time domain (time), and similarly, a plurality of frequency domain units may be divided in a frequency domain (frequency). Further, the mini-slot may be a resource defined by one time domain unit and one frequency domain unit. For example, in said FIG. 2The noted mini-slot 0 may be the time-domain unit [ t ]_start,t_start+τ]And frequency domain unit

A defined resource; as another example, the mini-slot 2 labeled in FIG. 2 may be a time domain unit [ t ]_start+2τ,t_start+3τ]And frequency domain unit

A defined resource.

Wherein the minislots may be used to carry blocks of media data, and the size of the minislots is adjustable, and correspondingly, the size of the blocks of media data is also variable. For example, based on the technical solution of the embodiment of the present invention, the network may adjust the size of the mini slot at any time to adjust the size of the media data block according to the number of the user devices that need to be served and the traffic demand of each user device; alternatively, the size of the media data blocks may be adjusted individually without changing the size of the mini-slots. Of course, the mini-slot may also be used to carry various other suitable data.

Further, the minislots may be slots (slots) used in the prior art. Preferably, the mini-slot may also be a newly defined time interval (time interval) with a length smaller than that of the existing time slot, and the mini-slot may be dedicated to the license-free resource adopting the technical solution of the embodiment of the present invention.

Further, the different minislots may not overlap in the time and frequency domains.

Further, the multiple user equipments adopting the technical solution of the present embodiment may access the same or different mini-slots in the multiple mini-slots without authorization according to the allocation of the network.

Further, the user equipment may determine that the network provides the unlicensed resource according to the indication information. In one non-limiting embodiment, the user equipment may further preliminarily determine the location of the unlicensed resource in the time domain and the frequency domain according to the indication information. Specifically, the indication information may indicate an approximate range of the unlicensed resource in a time domain and a frequency domain, so that the user equipment may determine whether the user equipment has a hardware capability of accessing the unlicensed resource. For example, whether the frequency search range of the user equipment can cover the frequency domain of the license-exempt resource indicated by the indication information.

Further, the indication information may also be used to indicate the size and quality of the unlicensed resource. For example, when the ue has not accessed the network, the indication information may be received first, and it may be determined whether to access the network to use the unlicensed resource of the network according to the indication information.

Preferably, the indication information may include resource-related indication information, where the resource-related indication information may be used to instruct the ue to obtain resource status information, where the resource status information is used to indicate a currently unallocated resource (or load) in the unlicensed resource. For example, the resource status information may be expressed in terms of a percentage.

Further, the resource-related indication information may also be used to indicate that the user equipment acquires device-related information, and the device-related information may be used to indicate a block error rate and an average delay that the user equipment accessing the unlicensed resource needs to experience.

Preferably, the resource-related indication Information may be transmitted together with the indication Information through necessary System Information (Master System Information, MSI for short). Further, the resource related indication information may indicate that the user equipment receives the resource state information and/or the device related information through RRC dedicated signaling.

Further, the unlicensed resource information may further include a set of unlicensed resource parameters describing a distribution of the plurality of mini-slots over time and frequency domains.

Preferably, with continued reference to fig. 2, the set of unlicensed resource parameters may include at least any one or any number of the following parameters: start of the unlicensed resourceTime t_startEnd time t_end(ii) a Starting frequency f of the unlicensed resource_startEnd frequency f_end(ii) a The duration τ of each of said minislots in the time domain; the partition (or interval) of the authorization-free resource on the frequency domain

An elongation parameter of the microgap; and a periodicity of the unlicensed resource.

Wherein, in the time domain, the unlicensed resource is at the start time t_startAs a starting point, with the end time t_endThe end point is, and the time duration of each micro-gap in the time domain is tau. In one non-limiting embodiment, the start time t is received according to_startEnd time t_endAnd the duration τ, the user equipment may determine a number of units in which an unlicensed resource of the network is partitioned in a time domain. In particular, the formula n can be used_τ＝(t_end–t_start) Is represented by/τ, wherein n is_τThe number of units divided in time domain for the unlicensed resource of the network, t_endAs the end time, the t_startFor the start time, τ is the time duration of each of the mini-slots in the time domain.

Wherein, in the frequency domain, the unlicensed resource is at the starting frequency f_startStarting from the end frequency f_endThe end point is, and the interval of each micro-gap on the frequency domain is

In one non-limiting embodiment, the starting frequency f is received according to_startEnd frequency f_endAnd the section

The user equipment may determine a number of cells into which an unlicensed resource of the network is partitioned in a frequency domain. Further, combined withThe user equipment may determine the number of mini slots included in the unlicensed resource, based on the determined number of cells into which the unlicensed resource of the network is divided in the time domain. In particular, a formula can be used

Is shown, wherein, the

A number of units divided in a frequency domain for an unlicensed resource of the network, f_endFor the end frequency, the f_startFor the start frequency, the

For each of said minislots an interval in the frequency domain.

Wherein the periodicity of the unlicensed resource may be used to indicate that the unlicensed resource is available for a given time period for the user device to access the unlicensed resource when the given time period comes. In particular, the periodicity may be a time interval during which the unlicensed resource is again available to the user equipment. For example, the unlicensed resource may be repeated according to a preset period, and the user equipment may be unlicensed to access the resource when the unlicensed resource is available according to the periodic parameter.

Wherein the mini-slot extension parameter may be used to indicate whether the user equipment is allowed to use consecutive mini-slots for data transmission, i.e. whether the user equipment allocated one mini-slot is able to continue data transmission in the next mini-slot. For example, if the extension parameter of the mini-slot allocated to the user equipment is 1, it may indicate that the network allows the user equipment to continue transmitting data on the mini-slot next to the allocated mini-slot; if the extension parameter of the mini-slot allocated to the user equipment is 0, it may indicate that the network does not allow the user equipment to continue data transmission in the mini-slot next to the allocated mini-slot. Further, when the extension parameter of the mini-slot allocated to the user equipment is 1, the network may implicitly indicate that the user equipment is allowed to perform data transmission (or retransmission) in one or more mini-slots subsequent to the allocated mini-slot. Preferably, the implicit indication may be indicated by an extension parameter of the mini-slot, or by another parameter of the set of unlicensed parameters.

Further, the specific value of the elongation parameter of the mini-slot may be controlled by the network. For example, the network may allocate the extension parameters of the mini slots to different user equipments during RRC signaling interaction with the user equipments, respectively.

Further, not every user equipment requesting license-free access to the URLLC resource may be allocated an extension parameter of the mini-slot. Those skilled in the art will appreciate that the network may limit the number of user devices that may continue data transmission in the mini-slot next to the allocated target mini-slot by disabling the mini-slot extension parameter (e.g., setting the mini-slot extension parameter to 0). For example, the network may assign an extension parameter for the mini-slot to user equipments with higher priority traffic to transmit, to ensure that these user equipments can upload all traffic during the current period of unlicensed resources. Further, the extension parameter of the mini-slot may be allocated according to the service that the ue needs to transmit, for example, if a ue may have two services to upload in total, where the priority of one service is high and the priority of the other service is low, the network may allocate the extension parameters of the two mini-slots to the ue, where the extension parameter of the mini-slot corresponding to the high-priority service is 1, so that the ue may completely upload the high-priority service in an unlicensed resource period; on the other hand, the extension parameter of the mini-slot corresponding to the low-priority service is 0, and if the ue fails to upload all the contents of the low-priority service in one period of the unlicensed resource, the ue may wait until the next period of the unlicensed resource to continue uploading the remaining contents of the low-priority service.

Alternatively, the mini slot extension parameter may be based on the user equipment setting (e.g., some user equipments may only transmit a specific type of traffic). In such a scenario, the priority may be determined according to the ue, and then a uniform mini slot extension parameter may be set for all services of the ue.

As a variation, the set of unlicensed resource parameters may further include parameters: time identification (time ID for short) and frequency identification (frequency ID for short), where the time identification may replace two parameters of start time and end time of the unlicensed resource to indicate a time domain resource of the unlicensed resource, and the frequency identification may replace two parameters of start frequency and end frequency of the unlicensed resource to indicate a frequency domain resource of the unlicensed resource.

Those skilled in the art will understand that the introduction of the mini-slot in the embodiments of the present invention is to prevent resource waste (e.g., unused resources), because, for an application scenario as an example, the URLLC should be composed of multiple data packets, each data packet occupies 20 bytes, and each ue is theoretically allowed to use only 20 bytes of the URLLC for uplink data transmission, so as to ensure that as many ues as possible can enjoy the resource service of the URLLC. If a user equipment needs more resources (more than 20 bytes of resources), the user equipment can continue uplink data transmission (or retransmission) in the mini-slot or mini-slots next to its allocated mini-slot only if the network indicates that the mini-slot extension parameter for the user equipment is 1.

Further, the network may ensure that there is not too much access to a mini-slot by means of the extension parameter of the mini-slot, e.g. if the extension parameter of the mini-slot is not disabled for a particular user equipment, it may be the case that a mini-slot may be accessed by user equipments not allocated to this mini-slot by the network in addition to the user equipment allocated to this mini-slot by the network (these user equipments may be allocated to the last mini-slot of the mini-slot by the network, but fail to upload in the last mini-slot due to too much data that needs to be uploaded, since the network does not disable the extension parameter of the mini-slot of these user equipments, so that these user equipments all go forward to the mini-slot for upstream data transmission), such a scenario may cause the mini-slot to operate in an overload state, thereby affecting the data transfer speed of all user devices accessing the mini-slot. Therefore, the network can control the number of user equipments accessing the mini-slot by setting the extension parameter of the mini-slot to 0.

Preferably, the parameter content and the specific value of each parameter included in the set of unlicensed resource parameters may be different for different types of user equipment. For example, if n types of user equipments (all supporting unlicensed) currently join the network, the network may include n sets of the unlicensed resource parameter sets in System Information (SI) sent by the network, so as to correspond to the n types of user equipments. Further, the user equipment may selectively receive a corresponding set of unlicensed resource parameters according to its type; or, the ue may also receive all sets of unlicensed resource parameters sent by the network, and select a set of unlicensed resource parameters corresponding to its type from the sets of unlicensed resource parameters.

Preferably, the System Information may include MSI, and may also include Other System Information (OSI). As a variation, the network may also send the set of unlicensed resource parameters to the user equipment through RRC signaling. For example, the network may identify the type of the user equipment during the RRC connection establishment with the user equipment, and then, after the RRC connection establishment, send an unlicensed resource parameter set corresponding to the type of the user equipment in a targeted manner through RRC signaling.

As a variant, for the same unlicensed resource, the holding of each mini-slot in the time domainDuration τ and/or interval of the unlicensed resource over frequency domain

May not be unique, i.e., the unlicensed resources may not be equally partitioned in the time and/or frequency domain. In particular, the network may indicate by further parameters of the unlicensed resource, so that the user equipment may determine the number of mini-slots, the start time, the end time, the start frequency, and the end frequency of each mini-slot included in the unlicensed resource. Those skilled in the art understand that, for the above scenario of equal partition of unlicensed resources, the user equipment may divide the resource according to the starting frequency f_startAnd the interval of the license-free resource on the frequency domain

And the start time t_startAnd the duration τ of each mini-slot in the time domain determines the state of partitioning of the unlicensed resource; for the scenario of the non-equal partition of the unlicensed resource in this variation, the ue needs to obtain more parameter information to determine the partition state of the unlicensed resource. However, one advantage of this variation is that it allows the network to more flexibly plan the unlicensed resources to better accommodate user devices with different traffic demands.

Further, the configuration response information includes a configuration ID associated with the user equipment sending the request for exemption and an ID function for the user equipment to determine the target mini-slot according to the configuration ID, and the ID function causes the plurality of user equipment sending the request for exemption to be directed to different target mini-slots.

Preferably, the ID function may also be used to indicate the time and frequency domain ranges of the mini-slot (i.e. the target mini-slot) that the user equipment may access at the present time.

Preferably, the ID function may be used to ensure that a plurality of user equipments requiring access to unlicensed resources of the same network can be uniformly distributed in different minislots (i.e. resource blocks, which may also be referred to as data packets) to better prevent resource waste.

Further, a portion of mini-slots included in the unlicensed resource may be respectively allocated to be dedicated to a single user equipment, and the remaining mini-slots other than the portion of mini-slots may be respectively allocated to be shared by a plurality of user equipments. For example, when a user device has a large amount of important traffic to send over the unlicensed resource, the network may assign it to a dedicated target mini-slot; for another example, if a user device has only a few scattered traffic to upload, the network may assign it to a shared target mini-slot.

Preferably, the configuration ID has uniqueness, nonnegativity, and corresponds to the user equipment one to one. In a non-limiting embodiment, for a ue that first requests access to an unlicensed resource of the network, the network provides a new config ID to the ue, where the new config ID is different from respective config IDs of other ues currently connected to the network, so as to facilitate network identification.

Further, the configuration ID may be associated with a traffic type of a traffic that the user equipment may transmit through the unlicensed resource. For example, if one user equipment needs to transmit services of a plurality of different service types, and each of the services needs to be transmitted through the unlicensed resource, the network may assign a plurality of different configuration IDs to the user equipment. Wherein the configuration ID may correspond to the service type one to one. Based on such a scheme, the services of different service types that the user equipment needs to transmit can be transmitted through different target mini-slots.

For example, among the services that the ue needs to send, according to the assigned configuration ID, the service with higher priority of the service type may be directed to a dedicated target mini slot; as another example, traffic of a traffic type having a lower priority may be directed to a shared target mini-slot based on an assigned configuration ID (which may be different from the aforementioned configuration ID).

Alternatively, if the services that the user equipment needs to transmit are all of one service type (or the service types of the services are very similar, such as having similar priorities), the network may assign only one configuration ID to the user equipment, where the configuration ID is associated with each of the services.

Further, the user equipment may determine a target mini-slot to be accessed according to the configuration ID and an ID function sent by the network, and during connection with the network, when there is a data transmission need, the user equipment may access the target mini-slot for data transmission (e.g., uplink data transmission). Those skilled in the art will understand that if the ue and the network are always connected, the configuration ID assigned to the ue will not change, so if the parameter set of the unlicensed resource sent by the network does not change, the ue may store information (such as the parameter set of the unlicensed resource, the configuration ID, the configuration response information, etc.) required for accessing the unlicensed resource, and start from the second generation of the request for accessing the unlicensed resource, not send the request for access to the unlicensed resource to the network (i.e., step S102 may be omitted), but directly access the target mini-slot based on the stored information.

As a variation, since the ue cannot determine whether the parameter set of the unlicensed resource changes, before accessing the unlicensed resource each time, the ue may also obtain the latest parameter set of the unlicensed resource through the MSI broadcasted by the network; alternatively, the ue may also send an on-demand request to request that the unlicensed resource parameter set be received over an OSI; still alternatively, the ue may further send an on-demand request to request that the unlicensed resource parameter set be obtained by means of dedicated signaling. Alternatively, after connecting to the network, the user equipment may further acquire the set of unlicensed resource parameters through RRC signaling.

Further, the network may include a plurality of base stations, and the user equipment may obtain different configuration IDs from the plurality of base stations to access, based on the different configuration IDs, the unlicensed resources (e.g., URLLC resources) allocated to the respective base stations by the network, respectively. For example, when the user equipment moves from the signal coverage of one base station included in the network to the signal coverage of another base station, the user equipment may listen to the MSI broadcast by the new base station (i.e., the another base station) to access the URLLC resource of the new base station. Further, the ue may monitor MSIs respectively broadcast by different base stations to know quality of URLLC resources of the base stations, and further select a base station with the highest quality from the MSIs to establish a connection to access URLLC resources of the base stations.

Further, the step S103 may include the steps of: substituting parameters included in the configuration ID and unlicensed resource parameter set into the ID function to determine the target mini-slot to which the configuration response information points; the target mini-slot is accessed. Preferably, the ID function may be a mapping function.

In a preferred embodiment, the ID function may include a remainder function, e.g., may be based on a function L_{Target microgap}MOD (configuration ID, n)_τ) Positioning the target microgap, wherein the L_{Target microgap}For the location of the target mini slot, f (configuration ID) is a mapping function based on the configuration ID, MOD () is a remainder operation, n_τA number of units divided in a time domain for an unlicensed resource of the network. In particular, with continued reference to fig. 2, assuming that n +1 mini-slots are numbered sequentially from 0 to n (i.e. the license-exempt resource includes n +1 mini-slots from mini-slot 0 to mini-slot n), for a first user equipment (not shown in the figure) requesting access to the license-exempt resource, it may be assigned a configuration ID of 0, since MOD (0, n) is 0, the user equipment may access mini-slot 0; for a second user equipment (not shown) requesting access to the unlicensed resource, which may be assigned a configuration ID of 1, since MOD (1, n) is 1, the user equipment may access mini-slot 1; accessing the license-exempt resource for a third requestUser equipment 1, which may be assigned a configuration ID of 2, may access mini slot 2 since MOD (2, n) is 2; by analogy, for the (n + 1) th user equipment requesting access to the unlicensed resource, it may be assigned a configuration ID of n, which is in turn assigned to the mini-slot 0 since MOD (n, n) is 0.

It is understood by those skilled in the art that, with the technical solution of the preferred embodiment, when the mini-slot n is allocated to a user equipment, there is a high probability that the user equipment previously allocated to the mini-slot 0 has already finished accessing the mini-slot 0, so that, for the next user equipment requesting access to the unlicensed resource, allocation can be performed from the mini-slot 0, so as to preferentially ensure that a plurality of user equipments requesting access to the same unlicensed resource can be allocated to different mini-slots, and as much as possible, each user equipment can obtain a higher channel access speed.

As a variation, the ID function may further include a mapping function such as a hash function that can uniquely correspond to the target mini-slot, and those skilled in the art may change further embodiments according to actual needs, which is not described herein.

As a variant, the ID function may also be hard-coded beforehand on the user equipment side. Specifically, the user equipment may determine the allocated target mini slot according to the received configuration ID in combination with an ID function hard-coded on the user equipment side in advance.

As another variant, the ID function may also be omitted, and the network may, upon request by the user equipment, allocate the target mini-slot to the user equipment in dependence on the availability of its unlicensed resources, and indicate the allocated target mini-slot directly to the user equipment.

Further, the request for authorization exempt is sent via an OSI request. For example, the user equipment may mark the unlicensed request in an OSI request sent to the network to better save signaling overhead when access to unlicensed resources of the network is required. As a variant, the request for authorization exemption may also be sent by RRC signaling.

In a variation, for a user equipment already connected to the network, when it needs to access an unlicensed resource (e.g., a URLLC resource) of the network, an on-demand request may be sent to the network, and then response information for the network is received in OSI sent by the network and use of the URLLC resource is started based on the response information. Wherein the response information may be used to indicate that the network will subsequently transmit the configuration response information to the user equipment in a unicast form; alternatively, the response Information may also be used to instruct the ue to wait for the next necessary System Information (Master System Information, abbreviated as MSI) to obtain the configuration response Information broadcasted by the network from the MSI, and those skilled in the art understand that although such a scheme may result in a long waiting time and affect the strict delay requirement of the URLLC on data, signaling overhead may be further saved, and those skilled in the art may select appropriate response Information according to actual needs.

In a preferred application scenario, referring to fig. 1 and 2, the duration of each mini-slot included in the unlicensed resource in the time domain is τ, the configuration ID allocated by the network to the user equipment 1 is 2, and based on the ID function provided by the network, the user equipment 1 determines that its allocated mini-slot is a time period [ t [ t ] ]_start+2τ,t_start+3τ]A defined micro-gap. Further, the network may also indicate, through the configuration response message, the frequency range of the mini slot allocated to the user equipment 1 this time, assuming that the frequency range this time is

The user equipment 1 may determine that the mini-slot to which it is allocated this time is the mini-slot 22, i.e. the user equipment 1 may be in the time period t_start+2τ,t_start+3τ]Uplink data transmission is performed on the mini-slot 22.

Further, in this application scenario, when the extension parameter of the mini-slot in the received unlicensed parameter set is 1, the ue 1 may obtain a more-than-once data transmission opportunity, that is, if the ue 1 cannot complete all uplink data transmissions on the mini-slot 2, it may continue data transmission (or retransmission) in the mini-slot 3 (not shown in the figure).

Further, in the application scenario, when the number of the user equipments requesting to access the unlicensed resource is less than or equal to the number of mini-slots included in the unlicensed resource, each user equipment may be preferentially allocated to a different mini-slot, that is, each user equipment may obtain dedicated channel access, so that no collision occurs when each user equipment performs uplink data transmission on its respective mini-slot. However, when the number of user devices requesting access to the unlicensed resource is greater than the number of mini-slots included in the unlicensed resource, a plurality of user devices may need to share one mini-slot, and a conflict may occur. Further, the user equipment may reattempt a transmission operation when a collision occurs.

Fig. 3 is a flow chart of a variant implementation of the first embodiment of the invention. Wherein the unlicensed resource information may be received before a connection is established with the network.

In particular, the network may decide to allocate shared unlicensed resources for user equipments that do not satisfy a preset condition (e.g., allocate these user equipments to the same target mini-slot); it may also be decided to allocate dedicated unlicensed resources to user equipments meeting the preset condition (e.g. to allocate these user equipments to different target mini-slots, and the allocated target mini-slots are not reallocated to other user equipments within a preset time period). For example, the preset condition may be whether the ue has a higher delay limit, and if the ue has the higher delay limit, which indicates that the ue meets the preset condition, the network may preferentially allocate a dedicated unlicensed resource to the ue.

step S201, receiving authorization-free resource information sent by a network, where the authorization-free resource information includes indication information at least used for locating an authorization-free resource of the network, and the authorization-free resource includes a plurality of mini slots.

Step S202, judging whether to establish connection with the network according to the indication information.

And step S203, when the judgment result shows that the connection with the network is established, the connection with the network is established.

Step S204, an authorization-free request is sent to the network.

Step S205, accessing a target mini-slot in the unlicensed resource according to the information of the unlicensed resource and configuration response information, where the configuration response information is sent by the network in response to the request for unlicensed resource and is directed to the target mini-slot.

More specifically, the technical principle of step S201 may refer to the related description of step S101 in fig. 1, which is not repeated herein; for the technical principle of the step S204, reference may be made to the related description of the step S102 in fig. 1, which is not repeated herein; for the technical principle of step S205, reference may be made to the related description of step S103 in fig. 1, which is not repeated herein.

Further, when the determination result of the step S202 is affirmative, the step S203 is executed; otherwise, when the determination result of the step S202 is negative, the flow of the present embodiment may be ended. Further, when the determination result in the step S202 is negative, the ue may further search for unauthorized resource information of other networks, so as to continue to execute the technical solution of this embodiment when determining to establish a connection with the network.

For example, when the indication information indicates that the percentage of the currently unallocated unlicensed resources to the unlicensed resources is zero (that is, the currently unallocated unlicensed resources, which includes a plurality of mini-slots that are already allocated), the user equipment may determine not to establish a connection with the network in the step S102.

For another example, in executing step S102, if the indication information indicates that the percentage of the currently unallocated resource in the unlicensed resource is not zero, and the indication information also indicates that the block error rate and the average delay that a user equipment accessing the unlicensed resource of the network needs to experience meet the expectation of the user equipment, the user equipment may determine to establish a connection with the network.

Preferably, the unlicensed resource information may be transmitted by broadcast. For example, the unlicensed resource information is sent via an MSI (or other broadcast message), and the user equipment may acquire the indication information by listening to the MSI periodically broadcast by the network before joining the network. In a preferred embodiment, if the user equipment is in signal coverage of multiple networks, the user equipment may listen to MSI of each of the multiple networks to discover URLLC resources of each network, and select the network to which URLLC performance is best indicated to establish a connection.

As a variation, the ue may also send an on-demand request to request the network to obtain the unlicensed resource information, and accordingly, the network may respond to the ue through OSI (or any other dedicated message) and then send the unlicensed resource information to the ue through dedicated information, where the dedicated information may be sent in unicast. Alternatively, the network may also instruct the user equipment that it will broadcast the unlicensed resource information in the next broadcasted MSI. Specifically, the present variation will be further described with reference to fig. 4.

Fig. 4 is a flowchart of a specific implementation manner of step S101 in the first embodiment of the present invention. The difference between the method and the technical solution described in the embodiment shown in fig. 3 is that the unlicensed resource information may be received after establishing a connection with the network.

Specifically, in this embodiment, step S101 shown in fig. 1 may include the following steps:

step S1011, sending an on-demand request to the network, where the on-demand request is used to request to obtain the authorization-free resource information.

Step S1012, receiving response information sent by the network, where the response information is used to indicate a sending form and sending time of the authorization-free resource information.

Step S1013, receiving the authorization-exempt resource information according to the transmission form indicated by the response information at the transmission time indicated by the response information.

For example, the response information may be used to indicate that the unlicensed resource information is transmitted in the form of dedicated signaling, and then the step S1013 may include the steps of: and receiving the special signaling at the sending time indicated by the response information to acquire the authorization-free resource information.

For another example, the response information may also be used to indicate that the unlicensed resource information is to be transmitted in the MSI broadcasted next time by the network, and then the step S1013 may include the steps of: and when the network broadcasts the MSI next time, the MSI is listened to acquire the authorization-free resource information.

In a variation, if the ue sends the authorization exempt request in the connected state, the network may also allocate the configuration ID and ID functions to the ue in the RRC establishment process, and feed back to the ue through the dedicated signaling or MSI.

For example, when the ue establishes a connection (e.g., RRC connection) with the network, the ue may request to acquire the unlicensed resource information in a connection request (e.g., RRC connection request) sent to the network, the network may learn, according to the RRC connection request, a type of a service that the ue needs to send based on the unlicensed resource at this time, and then the network may allocate an appropriate target mini-slot for the type of the service, and send response information to the ue after the RRC connection is established, the ue receives the response information based on the RRC connection with the network, and the response information is used to indicate a sending form and sending time of the unlicensed resource information. Further, the ue may receive the unlicensed resource information according to the transmission format indicated by the response information at the transmission time indicated by the response information, so as to access a target mini-slot allocated by the network to the ue for the service.

In a preferred application scenario, if the service that the ue needs to upload has a higher priority, the network may allocate a dedicated resource to the ue (i.e. the allocated target mini-slot is exclusively used by the ue). Alternatively, if the traffic that the ue needs to upload has a lower priority, the network may allocate a shared resource to the ue (i.e. the allocated target mini-slot is shared by multiple ues).

Further, if the service that the ue needs to upload is distributed, the network may preferentially allocate a shared resource to the ue, so as to better utilize the unlicensed resource.

Further, the RRC connection request may also be used to indicate to the network that the traffic it needs to upload is to be sent over URLLC, so that the network determines whether to allocate the unlicensed resources to the user equipment.

Further, in this variation, the unlicensed resource information may be sent to the ue through an RRC dedicated message. The RRC dedicated message may include an RRC connection request, an RRC response message, an RRC reconfiguration message, and the like, and those skilled in the art may also change more embodiments according to actual needs, which is not described herein.

In a preferred application scenario, the transmission form of the unlicensed resource information indicated by the response information may be through the response information, and the transmission time is immediate, that is, when the user equipment receives the RRC response, the unlicensed resource information may be obtained from the RRC response.

Fig. 5 is a schematic structural diagram of an apparatus for accessing an unauthorized resource according to a second embodiment of the present invention. Those skilled in the art understand that the authorization-free resource access device 5 of the present embodiment is used to implement the method technical solutions described in the embodiments shown in fig. 1 to fig. 4. Specifically, in this embodiment, the apparatus 5 for accessing an unlicensed resource includes a first receiving module 53, configured to receive information of an unlicensed resource sent by a network, where the information of the unlicensed resource includes indication information at least used to locate the unlicensed resource of the network, and the unlicensed resource includes a plurality of mini-slots; a first sending module 54, configured to send an authorization-exempt request to the network; an accessing module 55, configured to access a target mini-slot in the unlicensed resource according to the information of the unlicensed resource and configuration response information, where the configuration response information is sent by the network in response to the request for unlicensed resource and is directed to the target mini-slot.

Further, the unlicensed resource information further includes a set of unlicensed resource parameters describing a distribution of the plurality of mini-slots over a time domain and a frequency domain, and the access module 55 includes: a calculating submodule 551, configured to substitute parameters included in the configuration ID and the unlicensed resource parameter set into the ID function, so as to determine the target mini-slot pointed to by the configuration response information; an access submodule 552 for accessing the target mini-slot.

Preferably, the set of unlicensed resource parameters includes at least any one or any plurality of the following parameters: a start time and an end time of the unlicensed resource; a starting frequency and an ending frequency of the unlicensed resource; the duration of each of the minislots in the time domain; a partition of the license-exempt resource in a frequency domain; an elongation parameter of the microgap; a periodicity of the unlicensed resource.

Further, the request for authorization exempt is sent via an OSI request.

In a preferred embodiment, the unauthorized resource information is received before establishing a connection with the network, and the unauthorized resource access device 5 further includes: the judging module 51 is configured to, after receiving the authorization-free resource information sent by the network, judge whether to establish a connection with the network according to the indication information; and the connection module 52 establishes connection with the network when the judgment result shows that connection with the network is established.

Further, the license-exempt resource information is sent by broadcasting.

Preferably, the unlicensed resource information is transmitted through the MSI.

In a variation, the unlicensed resource information is received after establishing a connection with the network, and the first receiving module 53 includes: a first sending submodule 531, configured to send an on-demand request to the network, where the on-demand request is used to request to acquire the authorization-free resource information; a first receiving submodule 532, configured to receive response information sent by the network, where the response information is used to indicate a sending form and sending time of the unlicensed resource information; the second receiving submodule 533 is configured to receive, at the sending time indicated by the response information, the authorization-exempt resource information according to the sending form indicated by the response information.

Preferably, the response information is used to indicate that the unlicensed resource information is sent by using dedicated signaling, and the second receiving submodule 533 includes: a receiving unit 5331, configured to receive the dedicated signaling at the sending time indicated by the response information, so as to obtain the authorization-exempt resource information.

In another variation, the unlicensed resource information is received after establishing a connection with the network, and the first receiving module 53 includes: the request submodule 534 is configured to request to acquire the authorization-free resource information in a connection request sent to the network when establishing connection with the network; a third receiving sub-module 535, configured to receive response information sent by the network after connection establishment, where the response information is used to indicate a sending form and a sending time of the unlicensed resource information; the fourth receiving submodule 536 is configured to receive, at the sending time indicated by the response information, the authorization-exempt resource information according to the sending form indicated by the response information.

Preferably, the connection may include an RRC connection (RRC connection); accordingly, the connection request sent by the request sub-module 534 may include an RRC connection request (RRC connection request); accordingly, the response information received by the third receiving sub-module 535 may include an RRC response (RRC response).

It should be noted that, in this embodiment, the first receiving submodule 532 and the third receiving submodule 535 may be the same module, or may be two mutually independent modules that perform the same function. Similarly, the second receiving submodule 533 and the fourth receiving submodule 536 may be the same module, or may be two independent modules performing the same function.

For more details of the operation principle and the operation mode of the authorization-free resource access apparatus 5, reference may be made to the related descriptions in fig. 1 to fig. 4, and details are not repeated here.

Fig. 6 is a flowchart of a method for scheduling grant-free resources according to a third embodiment of the present invention. In this embodiment, the process of scheduling the unlicensed resource of the network from the network side may be described, so that the ue can access the unlicensed resource.

Specifically, in this embodiment, the method for scheduling unlicensed resources may be implemented according to the following steps:

step S301, sending authorization-free resource information, where the authorization-free resource information includes indication information of authorization-free resources at least used for locating a network, and the authorization-free resources include a plurality of mini-slots.

Step S302, receiving an authorization-free request sent by user equipment.

Step S303, in response to the authorization-exempt request, sending configuration response information to the user equipment, where the configuration response information points to a target mini-slot in the authorization-exempt resource, so that the user equipment accesses the target mini-slot according to the authorization-exempt resource information and the configuration response information.

More specifically, for the explanation of the terms in the present embodiment, reference may be made to the related descriptions in fig. 1 to fig. 4, which are not repeated herein.

Preferably, the specific value of the information included in the indication information (e.g. the percentage of the currently unallocated resource to the total resource) may be different for different types of user equipments, which may be caused by differences in communication characteristics of different types of user equipments, which may include channel access speed and the like. The user equipment type may be determined according to the classification of the capability level of the user equipment in the prior art. Alternatively, the network may determine an average value for different types of user equipments, and generate the indication information based on the average value, so as to improve the operating efficiency of the network.

Further, the step S303 may include the steps of: performing a detection operation to detect whether the user equipment is qualified for the unauthorized access; and when the detection result shows that the user equipment is qualified for the unauthorized access, sending the configuration response information.

Those skilled in the art will appreciate that when the user device is assigned the configuration ID by a network, it may be assumed that the user device has been allowed by the network to access the unlicensed resources of the network. However, in practical applications, the user equipment may not have the capability of unlicensed access, i.e. the user equipment may not be able to meet URLLC requirements (determined by the network, of the user equipment accessing its URLLC resources). The technical solution of the embodiment of the present invention allows the network to reject the request of the user equipment not meeting the requirement to access its URLLC resource, and this rejection operation may be performed before allocating the configuration ID, so as to better avoid resource waste. For example, if a ue sends the request for unlicensed access through an RRC connection request, but the ue does not have the capability of unlicensed access, the network may send a reject message to the ue through an RRC response message (RRC response message, also referred to as RRC response message for short) to reject the request of the ue. Further, the network may also send the rejection message through an RRC connection response (RRC connection response) or other RRC dedicated message.

In a preferred embodiment, the detecting operation may be performed after receiving an authorization exempt request sent by the user equipment. For example, after receiving the authorization-exempt request sent by the user equipment and before assigning the configuration ID to the user equipment, the network may perform the above-mentioned detection operation to determine whether to allow the authorization-exempt access requested by the user equipment.

In a variant, the detecting operation may be performed after establishing a connection with the user equipment. For example, after establishing a connection with the user equipment, the network may actively detect whether the user equipment meets the URLLC requirement set by the user equipment, even if the user equipment does not send the authorization exemption request at this time. Those skilled in the art will understand that the advantage of using this variation is that the URLLC has very strict latency requirements, and in practical applications, the URLLC resource should be accessible immediately when the ue does need to access the URLLC resource, so if the above preferred solution is used, the detection operation is performed after receiving the request of the ue without authorization, which may increase latency and affect the channel access speed.

Further, the request for authorization exempt may be received through an OSI request sent by the user device. Alternatively, for a user equipment that has established a connection, the request for authorization exemption may also be received via an on-demand request sent by the user equipment.

Further, the configuration response information includes a configuration ID associated with the user equipment and an ID function for the user equipment to determine the target mini-slot according to the configuration ID, and the ID function causes a plurality of user equipments sending the request for authorization exemption to be directed to different target mini-slots.

In a preferred example, the configuration ID may be taken from a monotonic sequence, for the plurality of user equipments, the configuration ID may be allocated according to a chronological order of receiving the request for exempting from authorization sent by each user equipment, and the target mini-slot pointed by the configuration ID is time-domain-wise delayed.

For example, the monotonic sequence may be an increasing sequence starting from 0, and for a first user device requesting access to an unlicensed resource, the configuration ID assigned to the user device by the network may be 0; for a second user device requesting access to an unlicensed resource, the network may assign a configuration ID of 1 to the user device; for a third user device requesting access to an unlicensed resource, the configuration ID assigned to the user device by the network may be 2; and so on, whenever an authorization exempt request sent by a new user equipment is received, the network selects a number which is not allocated in history and is ranked the top from the increasing sequence as the configuration ID allocated to the user equipment.

In a variation, the configuration ID may also be determined based on an identity of the user equipment. For example, the network may obtain a configuration ID of the ue by combining a hash algorithm according to an International Mobile Subscriber Identity (IMSI) of the ue, where the IMSI may be obtained when establishing a connection with the ue.

Further, when the user equipment leaves the network, the configuration ID assigned to the user equipment may be released for use by another user equipment. Further, when a user equipment leaving the network rejoins the network and requests access to the unlicensed resources of the network again, the network may assign a new configuration ID to the user equipment.

As a variant, a timer may be set for the config ID to prevent the target mini-slot of the URLLC to which the config ID points from being idle for a long time. For example, in response to the request for unauthorized resource access sent by a ue, the network assigns a configuration ID to the ue and reserves a mini-slot included in the unauthorized resource for the ue, but the ue does not access the mini-slot during the connection period of the ue to the network, so that the mini-slot is always in an idle state, which may result in a high possibility that other ues that do have the requirement for unauthorized resource access cannot enjoy the unauthorized resource access service of URLLC.

Therefore, in this variation, the network starts a corresponding timer for the configuration ID allocated to the ue while sending the configuration response information to the ue, and when the timer expires, if the ue does not access the allocated mini-slot, the network may release the configuration ID to another ue.

Further, for the application scenario that the unlicensed resource is allocated by RRC signaling, the network may also set a corresponding timer for the configuration ID allocated to the user equipment. For example, after the timer expires, if the network has not allocated the unlicensed resource to the ue, the ue may give up its unlicensed request (because the latency requirement of the ue may not be met at this time).

Alternatively, the present variation may be applied to a scenario in which the user equipment is temporarily disconnected from the network. For example, after the ue leaves the network, the network may start the timer for the configuration ID assigned to the ue, and before the timer expires, if the ue reconnects to the network again and requests access to the unlicensed resources of the network, the network may preferentially reassign the configuration ID to the ue again; however, if the ue reconnects to the network after the timer expires, the network may preferentially assign a new configuration ID to the ue when the ue requests access to the unlicensed resource of the network. For another example, in this scenario, the network may start a corresponding timer after the configuration ID is assigned to the ue, so as to increase the utilization rate of the mini-slot pointed by the configuration ID.

In a variation of this embodiment, in addition to the above technical solution of implicitly indicating the target mini-slot by configuring the ID and ID functions, the network may explicitly indicate the target mini-slot allocated to the user equipment by a direct designation. For example, the network may number a mini slot included in the unlicensed resource in advance and record the mini slot in a number list, and after receiving the unlicensed request, the network may indicate the number list and a number of a target mini slot allocated to the user equipment this time in configuration response information sent to the user equipment, and the user equipment may access the target mini slot according to the configuration response information.

Further, the network may allocate the unlicensed resources in a uniform manner until the unlicensed resources are changed.

Further, the network can dynamically set the unlicensed resources for one or more user equipments through RRC messages (also referred to as RRC signaling). For example, when more user devices join the network (or when the number of user devices requesting the network to allocate an unlicensed resource increases), the network may increase the number of mini-slots included in the unlicensed resource (e.g., adjust a resource in the general sense used in the prior art to the unlicensed resource); or, when a user equipment leaves the network (or the number of user equipments requesting the network to allocate the unlicensed resource decreases), the network may further release one or more mini-slots included in the unlicensed resource (e.g., adjust all or part of the unlicensed resource to the generally significant resource), so as to flexibly allocate the resource of the network, improve the resource utilization rate, and meet personalized requirements of different user equipments.

Further, the network may determine a corresponding ID function from the configuration ID assigned to the user device to allocate a different mini-slot (or unlicensed resource) for each user device or group of user devices requesting access to unlicensed resources.

Further, if the unlicensed resources of the network are updated, the network may reallocate its previously assigned configuration ID. For example, if the number of frequency resources and the number of mini slots included in the updated unlicensed resource change, the network needs to update the configuration ID so as to prevent the ue from using the updated unlicensed resource inefficiently.

Those skilled in the art understand that in practical applications, due to changes in traffic requirements, the possibility of the network to reconfigure its URLLC resources is not excluded, e.g. the start frequency f of the unlicensed resources is kept constant even if the configuration ID remains the same_startAnd an end frequency f_endAnd the duration τ of each of said minislots may vary in the time domain. As another example, the configuration of the unlicensed resource (e.g., parameters in the parameter set of unlicensed resources) changes (e.g., the number of media data blocks changes resulting in the original one mini-slot being partitioned into multiple mini-slots); for another example, when the number of user equipments joining the network increases, the unlicensed resource may increase accordingly; or, when the user equipment leaves the network, the unauthorized resource can be correspondingly reduced; for another example, the unlicensed resource may also be allocated based on traffic (e.g., dynamically adjusting the size of the unlicensed resource based on the amount of increase and decrease in traffic that needs to be transmitted over the unlicensed resource), and when this occurs, the ue may be assigned a new configuration ID to accommodate the change in the unlicensed resource; otherwise, some of the updated media data blocks may be unused and some of the updated media data blocks may be over-used.

Further, the unlicensed resource information may be transmitted by broadcast. Preferably, the unlicensed resource information may be transmitted through the MSI.

In a variation, the unlicensed resource information may also be sent in response to a request of the user equipment after establishing a connection with the user equipment. For example, the unlicensed resource information may be transmitted through an RRC message. This variation is further explained with reference to fig. 7.

Fig. 7 is a flowchart of an embodiment of step S301 in the third embodiment of the present invention.

Specifically, in this embodiment, step S301 shown in fig. 6 may include the following steps:

step S3011, receiving an on-demand request sent by the user equipment, where the on-demand request is used to request to acquire the authorization-free resource information.

Step S3012, sending response information to the user equipment, where the response information is used to indicate a sending form and sending time of the authorization-exempt resource information.

Step S3013, sending the authorization-exempt resource information according to the sending form indicated by the response information at the sending time indicated by the response information.

For example, the response information may be used to indicate that the unlicensed resource information is to be transmitted in the form of dedicated signaling, and then the step S3013 may include the steps of: and sending the dedicated signaling at the sending time indicated by the response information.

For another example, the response information may also be used to indicate that the unlicensed resource information is to be transmitted in the MSI broadcasted next time, and then the step S3013 may include the steps of: and broadcasting the authorization-free resource information when the MSI is broadcasted next time.

In a variation, if the request for license exemption is sent by the ue in a connected state with the network, the network may also allocate the configuration ID and ID function to the ue in an RRC establishment procedure, and feed back the configuration ID and ID function to the ue through the configuration response information.

Further, as another specific implementation manner of step S301 in the third embodiment of the present invention, step S301 may further include the steps of: receiving a connection request sent by the user equipment, wherein the connection request comprises a request for acquiring the authorization-free resource information; establishing a connection with the user equipment in response to the connection request; sending response information to the user equipment, wherein the response information is used for indicating the sending form and the sending time of the authorization-free resource information; and sending the authorization-free resource information according to the sending form indicated by the response information at the sending time indicated by the response information.

Those skilled in the art will understand that the above-described embodiment of fig. 7 may be applied to a scenario in which a network that has established a connection relationship with the ue receives an on-demand request of the ue in a connected state, and sends the unlicensed resource information in response to the on-demand request. Compared with the embodiment described in fig. 7, although the unlicensed resource information is also sent in response to the request of the user equipment after the connection is established, the difference of this embodiment is that the request of the user equipment may be received before or during the connection establishment.

Taking RRC connection as an example, based on the technical solution of this embodiment, in a process of establishing RRC connection with the network, the ue attaches request information to an RRC connection request sent to the network, where the request information is used to request to acquire the license-exempt resource information, and the network establishes RRC connection with the ue in response to the RRC connection request and indicates a sending form and sending time of the license-exempt resource information to the ue through an RRC response sent to the ue.

Those skilled in the art understand that the network and the user equipment adopting the embodiment can further save signaling overhead and improve the information interaction efficiency between the network and the user equipment.

Further, the response information may include an RRC response. For example, the network may indicate, through the RRC response, that the unlicensed resource information will be transmitted by the user equipment at a later time (i.e., the transmission time) through dedicated signaling. For another example, the network may also directly attach the grant-free resource information to the RRC signaling to further reduce signaling overhead.

In view of the above, with the scheme of the third embodiment, according to the parameter selected by the network (that is, the parameter included in the parameter set of the unauthorized resource), multiple accesses (shared resources may be accessed by multiple user equipments) may be provided for multiple user equipments, and a preset order of accesses (non-shared resources may be accessed by multiple user equipments) may be provided for multiple user equipments, and the unauthorized resource is more efficiently and fully used by flexibly allocating the unauthorized resource.

Fig. 8 is a schematic structural diagram of an apparatus for scheduling unlicensed resources according to a fourth embodiment of the present invention. Those skilled in the art understand that the unlicensed resource scheduling device 8 in this embodiment is used to implement the technical solution of the method in the embodiment shown in fig. 7. Specifically, in this embodiment, the apparatus 8 for scheduling unlicensed resources includes a third sending module 81, configured to send information of unlicensed resources, where the information of unlicensed resources includes indication information of unlicensed resources at least used for locating a network, and the unlicensed resources include a plurality of mini-slots; a fourth receiving module 82, configured to receive an authorization-exempt request sent by a user equipment; a fourth sending module 83, configured to send, in response to the authorization-exempt request, configuration response information to the user equipment, where the configuration response information points to a target mini-slot in the authorization-exempt resource, so that the user equipment accesses the target mini-slot according to the authorization-exempt resource information and the configuration response information.

Further, the fourth sending module 83 includes: a detection submodule 831, configured to perform a detection operation to detect whether the ue is qualified for unauthorized access; the second sending sub-module 832 sends the configuration response information when the detection result indicates that the user equipment is qualified for the unlicensed access.

In a preferred embodiment, the detecting operation is performed after establishing a connection with the user equipment.

As a variant, the detection operation is performed after receiving an authorization exempt request sent by the user equipment.

Preferably, the request for authorization exemption is received through an OSI request sent by the user equipment.

Preferably, the configuration IDs are taken from a monotonic sequence, for the plurality of user equipments, the fourth sending module 83 allocates the configuration IDs according to a time sequence of receiving the authorization exempting request sent by each user equipment, and the target mini-slots pointed by the configuration IDs are sequentially delayed in a time domain.

Further, the unlicensed resource information further includes a set of unlicensed resource parameters describing a distribution of the plurality of mini-slots over time and frequency domains.

In a preferred embodiment, the unlicensed resource information is transmitted by broadcast.

Preferably, the unlicensed resource information is transmitted through the MSI.

As a variation, the unlicensed resource information is sent in response to a request of the user equipment after establishing a connection with the user equipment.

Further, the third sending module 81 includes a second receiving submodule 811, configured to receive an on-demand request sent by the user equipment, where the on-demand request is used to request to obtain the authorization-exempt resource information; a third sending sub-module 812, configured to send response information to the user equipment, where the response information is used to indicate a sending form and sending time of the unlicensed resource information; a fourth sending sub-module 813, configured to send the authorization-exempt resource information according to the sending form indicated by the response information at the sending time indicated by the response information.

In a variation of this embodiment, the third sending module 81 may further include a third receiving sub-module 814, configured to receive a connection request sent by the user equipment, where the connection request includes a request for obtaining the license-exempt resource information; a connection establishing sub-module 815, which responds to the connection request and establishes connection with the user equipment; a fifth sending sub-module 816, configured to send response information to the user equipment, where the response information is used to indicate a sending form and sending time of the authorization-free resource information; and a sixth sending submodule 817, configured to send, at the sending time indicated by the response information, the authorization-exempt resource information according to the sending form indicated by the response information.

It should be noted that, in this embodiment, the third sending submodule 812 and the fifth sending submodule 816 may be the same module, or may also be two mutually independent modules that perform the same function. Similarly, the fourth sending submodule 813 and the sixth sending submodule 817 may be the same module, or may be two independent modules performing the same function.

For more contents of the operation principle and the operation mode of the license-exempt resource scheduling device 8, reference may be made to the related description in fig. 7, which is not described herein again.

In a typical application scenario, referring to fig. 9, a signaling interaction between a user equipment and a network using an embodiment of the present invention is further described. Those skilled in the art understand that the technical solution of the embodiment of the present invention defines a data transmission framework that can be used for URLLC and/or MTC. For convenience of description, in the application scenario, the user equipment accesses the URLLC resource (that is, the network is based on the authorization-free resource set by the URLLC) as an example, but the technical solution of the embodiment of the present invention is not limited thereto, and a person skilled in the art may apply the technical solution of the embodiment of the present invention to other data transmission technologies with low latency and high reliability according to actual needs.

Specifically, in the present application scenario, the unlicensed resource information may be received before establishing a connection with the network.

Further, with continued reference to fig. 9, the network 3 performs action s1 to periodically broadcast MSI, wherein the MSI includes the unlicensed resource information.

Further, when the user equipment 2 moves into the signal coverage of the network 3, action s2 may be performed to receive the network broadcast MSI and to obtain the unlicensed resource information from the MSI.

Further, for the user equipment 2 that may have a requirement for unauthorized resource access, act s3 may be performed to determine whether the unauthorized resource of the network 3 satisfies the expectation of the user equipment 2 based on the indication information included in the unauthorized resource information, and then determine whether to join the network 3.

Further, after determining to join the network 3, the user equipment 2 performs an action s4 to establish a connection with the network 3.

Further, upon establishing a connection with the user equipment 2, the network 3 may perform action s5 to detect whether the user equipment 2 is capable of unauthorized access to URLLC resources of the network 3.

Further, when the user equipment 2 generates a need to access an unlicensed resource of the network 3 during the connection with the network 3 or after being in a connected state with the network 3, the user equipment 2 may perform an action s6 to send an unlicensed request to the network 3. Wherein the request for authorization exempt may be sent via an OSI request.

Further, according to the result of the above detection operation, if the user equipment 2 has the capability of accessing the URLLC resource of the network 3 without authorization, the network 3 may execute action s7 to send the configuration response information to the user equipment 2 in response to the authorization-free request. Wherein the configuration response information comprises a configuration ID and an ID function, the configuration ID being associated with the user equipment 2.

Further, the user equipment 2 performs action s8 to receive the configuration response information, and accesses the target mini-slot pointed by the configuration response information according to the license-exempt resource information and the configuration response information.

In a variation of this application scenario, the network 3 may further perform the action s5 after the user equipment 2 has performed the action s 6.

For more contents of the working principle and working mode of the user equipment 2 and the network 3 in this application scenario, reference may be made to the related descriptions in fig. 1 to fig. 8, and details are not repeated here.

Fig. 10 is a signaling interaction diagram of another exemplary application scenario in which an embodiment of the present invention is employed. The difference from the application scenario shown in fig. 9 is that, in the application scenario, the unauthorized resource information may be received after establishing a connection with the network 3.

Further, with continued reference to fig. 10, the user equipment 2 has established a connection with the network 3. The user equipment 2 may perform action s9 to send an on-demand request to the network 3 requesting to obtain the unlicensed resource information.

Further, the network 3 performs an action s10 to send response information to the user equipment 2 in response to the on-demand request, where the response information is used to indicate a sending form and a sending time of the authorization-exempt resource information. Preferably, the response information may be transmitted through OSI; alternatively, it may be transmitted through RRC message.

Further, the network 3 also performs an action s11 to send the authorization-exempt resource information according to the sending form indicated by the response information at the sending time indicated by the response information.

Further, after receiving the response message, the user equipment 2 performs an action s12 to receive the authorization-exempt resource message according to the sending form indicated by the response message at the sending time indicated by the response message.

Further, when the user equipment 2 generates a need to access an unlicensed resource of the network 3, the user equipment 2 may perform the action s6 to send an unlicensed request to the network 3. Wherein the request for authorization exempt may be sent via an OSI request. If the user equipment 2 is enabled with an authorization-free access to URLLC resources of the network 3, the network 3 may perform action s7 to send the configuration response information to the user equipment 2 in response to the authorization-free request. Further, the user equipment 2 performs action s8 to receive the configuration response information, and accesses the target mini-slot pointed by the configuration response information according to the license-exempt resource information and the configuration response information. Specifically, those skilled in the art may refer to the related description in the application scenario shown in fig. 9, which is not described herein again.

Further, the network 3 may also perform the action s5 in the application scenario shown in fig. 9 described above when a connection is established with the user equipment 2 in a previous period or after the request for unauthorized access is received, so as to detect whether the user equipment 2 has an unauthorized access capability.

In a variation of this application scenario, the ue 2 may further request to acquire the unlicensed resource information through a connection request (e.g., an RRC connection request) sent to the network 3 during (or before) a connection (e.g., an RRC connection) with the network 3. Further, the network 3 establishes an RRC connection with the user equipment 2 in response to the RRC connection request, and performs the actions s10 and s11 to transmit the license-exempt resource information to the user equipment 2. Further, the user equipment 2 may also perform the action s12 to obtain the unlicensed resource information.

Further, the request for authorization exemption may also be sent through the RRC signaling. For example, the user equipment 2 may send the authorization exempt request through an RRC connection request sent to the network 3 when establishing an RRC connection with the network 3.

In a common variation of the application scenarios shown in fig. 9 and 10, if the ue 2 is already connected to the network 3 and has accessed an unauthorized resource of the network 3, the ue 2 may directly access the target mini-slot allocated to the ue 2 by the network 3 at the time of the first unauthorized access, without sending the unauthorized request again, from the second unauthorized access, on the premise that the connection status of the two is not changed and the configuration of the unauthorized resource is not changed.

In another common variation of the application scenarios shown in fig. 9 and 10 described above, the request for authorization exemption may also be sent via an on-demand request. For example, for a user equipment 2 already connected to the network 3, when there is a need to access URLLC resources of the network 3, the user equipment 2 may perform the action s6 in the form of sending the on-demand request, and then the operation of the network 3 to perform the action s7 may be decomposed into performing two actions: performing an action s71 to send response information to the user equipment 2 in response to the authorization-exempt request, the response information indicating a sending form and a sending time of the configuration response information; an action s72 is performed to transmit the configuration response information according to the transmission form indicated by the response information at the transmission time indicated by the response information. Wherein the response information may be transmitted through OSI.

Further, the operation of the user device 2 to perform the action s8 may be decomposed into performing two actions: performing action s81 to receive the response information; and performing an action s82, so as to receive the configuration response information according to the transmission form indicated by the response information at the transmission time indicated by the response information, and access the target mini-slot pointed by the configuration response information according to the license-exempt resource information and the configuration response information.

Preferably, the transmission form of the response information indication may include dedicated signaling; alternatively, the transmission form of the response information indication may further include the MSI broadcasted next time by the network 3.

Further, if the ue 2 sends the authorization exempt request in a connected state, the network 3 may also allocate the configuration ID and the ID function to the ue 2 in an RRC procedure.

Further, the embodiment of the present invention also discloses a storage medium, on which computer instructions are stored, and when the computer instructions are executed, the method technical solutions described in the embodiments shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 6, and fig. 7 are executed. Preferably, the storage medium may include a computer-readable storage medium. The storage medium may include ROM, RAM, magnetic or optical disks, etc.

Further, an embodiment of the present invention further discloses a terminal, including a memory and a processor, where the memory stores computer instructions capable of running on the processor, and the processor executes the technical solutions of the methods in the embodiments shown in fig. 1 to 4 when running the computer instructions. Preferably, the terminal may be the user equipment.

Further, the embodiment of the present invention also discloses a base station, which includes a memory and a processor, where the memory stores computer instructions capable of being executed on the processor, and the processor executes the computer instructions to execute the technical solutions of the methods in the embodiments shown in fig. 6 and fig. 7. Preferably, the base station may be in the network, the network interacts with the user equipment through the base station, and the user equipment may access the unlicensed resource of the network through the base station.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
