Detailed Description

The embodiments described in the present invention can be combined without conflict.

Fig. 1 is a schematic flowchart of a resource allocation method according to an embodiment of the present invention, where the resource allocation method shown in fig. 1 may be applied to a network side, such as a base station side, an Access Point (AP) side, a relay station side, and the like; as shown in fig. 1, the resource allocation method of the embodiment of the present invention includes the following steps:

step 101, when the signal quality of a signal carrying the authorization-free service of the UE is determined to be lower than a preset threshold, allocating carrier frequency resources for the authorization-free service.

In the embodiment of the invention, the parameters for representing the signal quality comprise parameters such as signal strength, signal to noise ratio and the like. The parameters of the Signal Strength include a Received Signal Strength Indicator (RSSI), a Signal power value, and the like. The preset threshold values are different according to different signal quality parameters; the preset threshold may be set as an empirical value. The carrier frequency Resource is specifically a time frequency Resource, and includes a Physical Resource Block (PRB) and the like.

In the embodiment of the present invention, the signal quality is lower than the preset threshold, as an example, the signal quality may be caused by interference due to multiple unlicensed services of the UE occupying the same time-frequency resource, or may be caused by poor performance of a carrier frequency resource scheduled for the unlicensed services due to the frequency selection characteristic of the UE.

If the network side resolves more than two UE identifications or authorization-free service identifications in the same uplink time-frequency resource, it is determined that authorization-free service conflicts exist in the uplink time-frequency resource, and the time-frequency resource needs to be reallocated for the authorization-free services of the more than two UEs, so as to ensure that the conflicting authorization-free services are retransmitted to the network side in time, and delay and reliable transmission of the services are achieved. If the network side determines that the signal-to-noise ratio of the signal is lower than the preset threshold value due to poor transmission signal of the authorization-free service, time-frequency resources need to be reallocated for the authorization-free service with the signal-to-noise ratio lower than the preset threshold value, so as to ensure that the authorization-free service is retransmitted to the network side in time, and delay and reliable transmission of the service are achieved.

In this example, the network element such as the base station, the access point, or the relay station may be a network element on the network side in the 5G mobile communication system.

And 102, loading the information of the carrier frequency resource in scheduling information.

And the scheduling information comprises information of time-frequency resources distributed for the authorization-free service.

Step 103, sending the scheduling information to the UE.

In the embodiment of the invention, after the corresponding time-frequency resources are allocated to the authorization-free service, the allocated time-frequency resources are loaded in the scheduling information to generate the corresponding scheduling information, and the scheduling information is respectively sent to the UE corresponding to the authorization-free service, so that each UE can resend the conflict authorization-free service on the allocated time-frequency resources.

In the embodiment of the present invention, the scheduling information further includes identification information of the authorization-free service corresponding to the allocated time-frequency resource.

As an implementation manner, a network side may pre-configure a process number of an authorization-free service for each UE, and notify the pre-configured process number of the authorization-free service to each UE in advance, and each UE receives the process number of the authorization-free service and configures itself; in this example, when the UE sends the authorization-exempt service, the process number of the sent authorization-exempt service is default to the process number that is pre-configured for the UE by the base station, and since the base station configures the process number for the UE in advance and notifies each UE, the process number is not carried when the authorization-exempt service is sent to the network side. When the network side sends scheduling information to the more than two UEs, the process number configured for each UE in advance is used as the identification information of the authorization-free service, and the allocated time-frequency resource and the process number of the authorization-free service are sent to the corresponding UE through the scheduling information.

As another implementation manner, the network side does not configure the process number of the unlicensed service in advance, but the UE side sets the process number of the unlicensed service by itself, and carries the process number that the UE sets for the unlicensed service to be sent when sending the unlicensed service to the network side. And the network side acquires the corresponding process number in the authorization-free service from the authorization-free services of the more than two UEs, and takes the acquired process number as the identification information of the authorization-free service. After receiving the authorization-free service sent by the UE, the network side acquires the process number corresponding to the authorization-free service, and after distributing corresponding time-frequency resources for the authorization-free service of the UE, sends the distributed time-frequency resources and the process number distributed by the UE for the authorization-free service to the corresponding UE through scheduling information.

As another implementation manner, in the embodiment of the present invention, a network side determines sending micro-slot (mini time slot) information of the scheduling information and receiving mini time slot information of the unlicensed service; and calculating time delay indication information based on the sending mini time slot information and the receiving mini time slot information, and loading the time delay indication information in the scheduling information.

Specifically, the network side may indicate the indication of the unlicensed service by sending a Downlink control information indication (DCI) to the UE, where the DCI is used as the scheduling information. At this time, the DCI carries the delay indication information, for example, the delay indication information is n-k. The meaning of n-k includes, for the delay information carried in the grant traffic received at the minislot (mini slot) n, indicating the scheduling of the grant-less traffic with respect to the k-th mini slot preceding the mini slot n.

As another implementation manner, in the embodiment of the present invention, a corresponding relationship between the process number of the unlicensed service and the current mini time slot number and the uplink mini time slot number of the unlicensed service may also be preconfigured, so that the process number of the unlicensed service is determined based on the current mini time slot number and the uplink mini time slot number and the corresponding relationship. The current mini time slot number is the time slot number of the mini time slot in which the scheduling information is currently located, that is, the mini time slot number of the current mini time slot used for scheduling the retransmission of the authorization-free service. And the uplink mini time slot number of the authorization-free service, namely the mini time slot number of the uplink mini time slot of the authorization-free service sent by the UE is received by the base station side. Specifically, the network side configures the corresponding relationship between the process number of the unlicensed service and the uplink mini time slot number of the unlicensed service and the current mini time slot number in advance, and can automatically determine which unlicensed service the current scheduling information is scheduled by the current mini time slot number and the uplink mini time slot number of the unlicensed service. For example, the process number of the unlicensed service to be retransmitted may be determined according to the following formula:

[(slot×number_of UL_minislot_per_slot)+index_of_UL_minislot]mod(number_of HARQ_processes)

wherein, slot represents slot number, number _ of UL _ mini _ per _ slot represents the number of uplink minislots in each slot, index _ of _ UL _ mini represents the index of uplink mini slot, and number _ of HARQ _ processes represents the number of HARQ processes.

It should be noted that, as those skilled in the art will appreciate, the above-mentioned manner of determining the process number of the unlicensed service by the timeslot number is merely an example, and the relationship between the current timeslot and the indicated process number of the retransmission unlicensed service may also be characterized by other functions.

In the embodiment of the invention, the authorization-free service comprises URLLC service. The authorization-free service can also be other low-delay and high-reliability services.

Fig. 2 is a flowchart illustrating a processing method of an authorization-exempt service according to an embodiment of the present invention, where the processing method of the authorization-exempt service shown in fig. 2 is applicable to a user equipment side. As shown in fig. 2, the method for processing an unauthorized service according to an embodiment of the present invention includes the following steps:

step 201, receiving scheduling information sent by a network side.

The scheduling information comprises information of carrier frequency resources allocated for the authorization-free service.

Step 202, resending the authorization-exempt service on the allocated carrier frequency resource.

The scheduling information also includes identification information of the authorization-free service corresponding to the allocated time-frequency resource.

In the embodiment of the invention, as an implementation manner, a network side can respectively configure the process numbers of the authorization-free service for each user equipment in advance; specifically, a process number for configuring the authorization-free service for the user equipment is sent to each user equipment on the network side. And the user equipment receives the process number used by the authorization-free service configured for the UE and sent by the network side. The identification information of the authorization-free service comprises a process number; correspondingly, before the user equipment receives scheduling information sent by the network side, the authorization-free service is sent on uplink time-frequency resources by using configured resources; that is to say, when the user equipment sends the authorization-exempt service for the first time, the process number of the default authorization-exempt service is the process number pre-configured by the network side, and the process number of the authorization-exempt service is not sent to the network side. Before retransmitting the authorization-free service on the allocated carrier frequency resource, the user equipment determines the authorization-free service based on the process number carried in the scheduling information. After receiving the scheduling information of the network side, the user equipment firstly determines which authorization-free service the scheduling information is for, and then sends the determined authorization-free service to the network side on the time-frequency resource indicated by the scheduling information.

In the embodiment of the present invention, as an implementation manner, the identification information of the authorization-free service includes a process number; correspondingly, before receiving scheduling information sent by a network side, sending the authorization-free service and a process number set for the authorization-free service on an uplink time-frequency resource; and before the authorization-free service is retransmitted on the allocated carrier frequency resource, determining the authorization-free service corresponding to the process number based on the process number carried in the scheduling information. In this example, when the user equipment first sends the authorization-free service, the user equipment arbitrarily selects a process number set by itself for the authorization-free service to be sent, and sends the selected process number and the authorization-free service together to the network side. The user equipment determines the authorization-free service corresponding to the process number based on the process number carried in the scheduling information of rescheduling the conflict authorization-free service sent by the network side, and sends the determined authorization-free service to the network side on the time-frequency resource indicated by the scheduling information.

In the embodiment of the present invention, as an implementation manner, the scheduling information further includes delay indication information; before retransmitting the authorization-free service on the allocated carrier frequency resource, the user equipment determines mini time slot information of the authorization-free service based on the time delay indication information and the current mini time slot information. Specifically, the network side may indicate the indication of the unlicensed service by sending a Downlink Control Information indication (DCI) to the UE, where the DCI is taken as scheduling Information. At this time, the DCI carries the delay indication information, for example, the delay indication information is n-k. The meaning of n-k includes, for the delay information carried in the grant traffic received at the minislot (mini slot) n, indicating the scheduling of the grant-less traffic with respect to the k-th mini slot preceding the mini slot n. After receiving the DCI, the UE determines that the authorization-free service to be retransmitted is the authorization-free service transmitted by the kth mini time slot before the current mini time slot n based on the time delay indication information n-k in the DCI, and retransmits the corresponding authorization-free service on the kth mini time slot before the mini time slot n on the time frequency resource indicated in the scheduling information.

As an implementation mode, the corresponding relation between the process number of the authorization-free service and the current mini time slot number and the uplink mini time slot number of the authorization-free service can be configured in advance. At this time, the scheduling information further includes retransmission indication information of the unlicensed service.

And when the user equipment determines that the scheduling information comprises the retransmission indication information, the current scheduling information is determined to be scheduling aiming at the authorization-free service, so that the current micro time slot number and the uplink mini time slot number of the authorization-free service are obtained, and the process number of the authorization-free service is determined based on the corresponding relation between the process number of the pre-configured authorization-free service and the current mini time slot number and the uplink mini time slot number of the authorization-free service. For example, the process number of the unlicensed service to be retransmitted may be determined according to the following formula:

It should be noted that, as those skilled in the art should understand, the above-mentioned manner of determining the process number of the unlicensed service by the mini timeslot number is only an example, and the relationship between the current mini timeslot and the indicated process number of the retransmitted unlicensed service may also be characterized by other functions.

The application scenario of determining the process number of the unlicensed service through the uplink mini timeslot number and the like described in this example is substantially the case of a synchronous Hybrid Automatic Repeat reQuest (HARQ).

The essence of the technical solution of the embodiment of the present invention is further clarified by specific examples below.

The technical scheme of the embodiment of the invention substantially records the dynamic switching between URLLC authorization-free service transmission and authorization service transmission. Specifically, during the process of sending the unlicensed service of the UE, the time-frequency resources occupied by the unlicensed services of other UEs may be the same, thereby causing a conflict between the unlicensed services, and at this time, the base station (gnB) may be required to perform time-frequency resource authorization again for the conflicting unlicensed services, and schedule the conflicting unlicensed services of each UE to different time-frequency resources, thereby reducing the transmission delay and improving the reliability. It is necessary for the UE to know whether the transmission of the grant service is for the same Transport Block (TB) as the transmission of the unlicensed service, i.e., the UE needs to determine whether the current schedule is for the retransmission of the previously sent unlicensed service.

In an application scenario of asynchronous HARQ, the technical solution of the embodiment of the present invention specifically includes the following implementation examples:

implementation example 1

And a process number used by the authorization-free service is pre-configured between the base station and the UE. For example, the unauthorized service process number is configured to be 0. When the base station determines that the authorization-free service conflict exists or the carrier frequency performance of the authorization-free service is not good, the base station can allocate carrier frequency resources for the conflict authorization-free service or the authorization-free service with poor carrier frequency performance, send scheduling information to the UE corresponding to the authorization-free service, and schedule the authorization-free service to the allocated time frequency resource position for retransmission. In this example, when the UE determines that the current service is the authorization-exempt service, the process number of the authorization-exempt service is defaulted to be the process number that is pre-configured by the base station for the UE, but since the base station previously sends the process number of the authorization-exempt service that is configured for the UE to the UE, the UE does not send the process number of the authorization-exempt service to the base station when sending the authorization-exempt service. After receiving the authorization-free service, the base station determines a corresponding process number for the current authorization-free service according to an authorization-free service process number pre-configured for the UE, and if the process number corresponding to the previous authorization-free service is 0, the process number of the currently received authorization-free service is 0; when the base station sends the scheduling information to the UE, the base station needs to inform the UE of the process number determined for the authorization-free service, and after the UE receives the scheduling information sent by the base station, the UE determines whether the current scheduling information is scheduled for the authorization-free service according to the process number of the authorization-free service included in the scheduling information, so that the corresponding authorization-free service is retransmitted on the time-frequency resource allocated by the scheduling information.

And carrying the time-frequency resource information distributed to the authorization-free service of each UE, the process number of the authorization-free service to be scheduled and the like in the scheduling information, and sending the scheduling information to the UE.

And the UE determines that the current scheduling information is the retransmission of the authorization-free service according to the process number in the scheduling information. If the process number carried in the scheduling information is the same as the process number of the previously sent authorization-free service, if the process number is the same, it is determined that the current scheduling information is the transmission of the same TB as the previously sent authorization-free service. And if the process number carried in the scheduling information is different from the process number of the previously sent authorization-free service, the current scheduling information is considered to be scheduling for other services.

Implementation example two

The base station carries delay indication information in the sent DCI, and takes the DCI as a part of scheduling information, for example, the delay indication is n-k. For the scheduling information received in the mini time slot n carries the delay indication information, it means that the delay indication information indicates the scheduling of the unlicensed service of the mini time slot k before the current mini time slot n. Fig. 3 is a schematic diagram of determining an unlicensed service process number based on delay indication information according to an embodiment of the present invention, as shown in fig. 3, where a time frequency resource represented by a hatched section bar covering part is an uplink time frequency resource, and is used for transmitting unlicensed uplink data. And black parts represent control information for scheduling of the unlicensed service.

After receiving the scheduling information, the UE first determines whether the current scheduling information is a retransmission or a new transmission of the service in which mini slot is located before. When the UE determines that the DCI carries the delay indication information, it determines that the current scheduling information is retransmission of a service in a previous mini time slot, and specifically, when the scheduling information received in the mini time slot n carries a delay indication of n-k, it means that the delay indication information indicates scheduling of a service in a mini time slot k before the current mini time slot n. In this example, the traffic of the mini time slot k before the mini time slot n is the unlicensed traffic.

Implementation example three

The base station can configure the UE to insert the process number information into the authorization-free service when the UE transmits the authorization-free service, namely, the process number information and the data are transmitted together. The process number information and the authorization-free service data are respectively and independently encoded, as shown in fig. 4 and 5, wherein, the hatched part represents the Reference Signal (RS), the blank area represents the data, and the black part represents the process number information; in this example, the process number information is encoded differently from the authorization-free service data. In this example, the process number used by the unlicensed service is not pre-configured between the base station and the UE. When the UE sends the authorization-free service, the UE determines the process number by the self-behavior authorization-free service and sends the process number determined for the authorization-free service and the authorization-free service together to the base station.

After receiving the authorization-free service sent by the UE, the base station acquires the process number corresponding to the authorization-free service, allocates time-frequency resources for the authorization-free service, carries the allocated time-frequency resources and the process number information of the authorization-free service corresponding to the time-frequency resources in scheduling information, and sends the scheduling information to the UE.

And after receiving the scheduling information, the UE determines which authorization-free service the current scheduling information is directed to according to the process number carried in the scheduling information, and retransmits the authorization-free service scheduled by the scheduling information on the allocated time-frequency resource.

Implementation example four

The present example may be applied to a synchronous HARQ scenario for an unlicensed service.

The base station pre-configures the corresponding relation between the process number of the authorization-free service and the uplink mini time slot number and the current mini time slot number of the authorization-free service, and the UE can determine the process number of the authorization-free service based on the current mini time slot number, the uplink mini time slot number of the authorization-free service and the corresponding relation. That is to say, for the synchronous HARQ scenario, when the base station side sends the scheduling information, the scheduling information only carries the time-frequency resource allocated by the base station, and does not carry the process number of the authorization-free service corresponding to the allocated time-frequency resource. At this time, after receiving the scheduling information sent by the base station, the UE may calculate the process number of the unlicensed service scheduled by the scheduling information according to the following formula:

And the UE receives the scheduling information sent by the gNB in the mini time slot n, and can calculate the process number of the authorization-free service scheduled by the scheduling information according to the information of the mini time slot n, so that the authorization-free service scheduled by the scheduling information is retransmitted on the allocated time frequency resources.

In the embodiment of the present invention, the base station may further set indication information whether the authorization-exempted service is a URLLC authorization-exempt service in an authorization-exempted service signal sent to the base station, for example, the indication information is 1bit to distinguish from other services, so that after the base station receives the authorization-exempted service signal, it is determined whether the current authorization-exempted service is a URLLC authorization-exempt service, and when it is determined that the current authorization-exempted service is a URLLC authorization-exempt service, carrier frequency resources are immediately allocated for the URLLC authorization-exempt service, thereby ensuring delay and transmission reliability requirements of the URLLC authorization-exempt service.

If the UE does not receive the scheduling information aiming at the authorization-free service sent by the base station, the UE resends the authorization-free service after the resending period of the authorization-free service comes; after the unlicensed service is retransmitted k times, the response message or scheduling information of the gNB is still not received, as shown in fig. 6; or the response message or scheduling information of the gNB has not been received within the time window m after k times of retransmission, as shown in fig. 7, the UE may perform one of the following two operation modes:

the first method is as follows: and the UE sends the authorization-free service to the base station again, performs k times of repetition, and waits for the gNB to send an Acknowledgement (ACK) to the UE.

The second method comprises the following steps: the UE triggers a Scheduling Request (SR) to the base station, and requests the base station (gNB) to schedule and transmit the authorization-free service.

The embodiment of the invention meets the requirements of low-delay and high-reliability transmission of URLLC authorization-free service and other services through the dynamic switching between the URLLC authorization-free service transmission and the authorization service transmission.
