Description

Wireless resource occupation method, acquisition method, user equipment and storage medium

Technical Field

The present disclosure relates to the field of wireless communication technologies, and in particular, to a method for occupying wireless resources, a method for acquiring wireless resources, a user equipment, and a storage medium.

Background

In LTE D2D (Device to Device) and LTE V2X (Vehicle to outside) wireless communication systems, user Equipment (UE) may communicate directly with each other. In the transmission process, there are multiple UEs in the same wireless resource pool, and when the UE performs a transmission service, the UE needs to occupy resource blocks in the resource pool.

In the prior art, a UE selects an idle resource block to occupy and transmit a service according to sensing history information of resource block busy and idle in a resource pool through sensing based semi-persistent scheduling (sensing based SPS). However, in the prior art, when the UE selects a free resource block meeting the predetermined condition, only 20% or less of the resource blocks are occupied for transmission service in order to ensure that other UEs in the resource pool can reasonably utilize the radio resources. This results in a lower utilization of resources and is not conducive to fast transmission.

Fig. 1 shows a flowchart of a method for occupying radio resources according to an implementation manner of the present disclosure. The method may be applied to a user equipment UE that needs to occupy radio resources for service, and specifically, as shown in fig. 1, the method may include:

s110: and selecting the occupiable resource blocks meeting the predetermined condition.

In some possible implementations of the present disclosure, the selection of the occupiable resource block may be selected by sensing, and specifically, the resource block meeting a predetermined condition may be selected by using a semi-persistent scheduling SPS based on sensing. Wherein the predetermined condition may be any one or more of the three conditions that the non-other UEs are camping on the resource block, RSRP is lower than the threshold, and the target UE is in the receiving slot (i.e. the resource block is in the receiving slot of the target UE). Specifically, the determination of the predetermined condition may be determined according to an actual resource requirement, which is not limited in this disclosure.

Fig. 3 shows a schematic diagram of a resource pool under an LTE V2X or LTE D2D framework. As shown in fig. 3, the pre-occupation period of the resource may be a predetermined value such as 100ms, 50ms, 25ms, and the like. The resource block may be used for transmitting PSCCH (Physical Sidelink Share Channel) and PSCCH (Physical Sidelink Control Channel).

The UE always senses the resource pool, when data needs to be transmitted, a selection window is determined according to the time delay requirement, the UE carries out statistical deletion and selection on the previous 1000ms resource pool use condition, and resource blocks meeting the conditions (non-other UE pre-occupied resource blocks, RSRP lower than a threshold and receiving time slots of target UE) are selected from candidate resource blocks of the selection window.

S120: and reserving a preset proportion of time slots in each occupation period as receiving time slots.

In some possible implementations of the present disclosure, the receiving timeslot may be used to receive resource requests SCI of other user equipments in the resource pool and/or feedback of the current service.

The resource request SCI may include request information of the other UE requesting the UE currently occupying the resource to release the resource.

The feedback of the current service may be HARQ (Hybrid Automatic Repeat reQuest) feedback or upper layer feedback.

The reservation refers to not occupying resource blocks in a reserved receiving time slot to perform the current service, but keeping the resource blocks idle, so as to receive resource requests SCI of other user equipment in a resource pool where the resource requests SCI and/or feedback of the current service. Of course, in some possible implementation manners of the present disclosure, the specific proportion of the reserved time slot may be reasonably allocated according to the resource requirement of the current service and the resource requirement of the receiving service, for example, 20% of the time slot may be reserved as the receiving time slot, and resource blocks in the receiving time slot are all kept idle to receive resource requests SCI of other user equipments in the resource pool where the resource requests are located and/or feedback of the current service. The present disclosure is not limited thereto.

S130: and according to the resource requirement of the current service, occupying part or all of the occupied resource blocks except the resource blocks of the receiving time slot in each occupied period.

Because there is reserved resource to ensure that other UEs can acquire the resource, the UE currently occupying the resource can continuously occupy a large amount of resource blocks, for example, occupy more than 80% of the occupied resource blocks or even occupy all the resource blocks. And releasing the resources when the resource request SCI is received and the resources need to be released so as to ensure that other UE can acquire the needed resources.

Of course, in a possible implementation manner of the present disclosure, the occupied resource blocks are part or all of the resource blocks outside the reserved receiving slot.

Fig. 2 shows a flow chart of a radio resource occupying method according to another implementation manner of the present disclosure. The method may be applied to a user equipment UE that needs to occupy radio resources for service, and specifically, as shown in fig. 2, the method may include:

s210: and selecting the occupiable resource blocks meeting the preset conditions.

In one implementation manner of the present disclosure, SPS based on semi-persistent scheduling may be adopted, and the occupiable resource blocks meeting the predetermined condition are selected.

In some possible implementations of the present disclosure, the selection of the occupiable resource block may be selected by sensing, and specifically, the resource block meeting a predetermined condition may be selected by using a semi-persistent scheduling SPS based on sensing. The predetermined condition may be any one or more of the three conditions that other UEs are camping on resource blocks, RSRP is lower than a threshold, and a receiving time slot of a target UE. Specifically, the determination of the predetermined condition may be determined according to an actual resource requirement, which is not limited in this disclosure.

S220: and reserving a preset proportion of time slots in each occupation period as receiving time slots.

Wherein the feedback of the current service may be HARQ feedback or upper layer feedback.

S230: and according to the resource requirement of the current service, occupying part or all of the occupied resource blocks except the resource block of the receiving time slot in each occupied period.

Because the reserved resources are provided to ensure that other UEs can acquire the resources, the UE currently occupying the resources can continuously occupy a large number of resource blocks, for example, occupy more than 80% of the occupied resource blocks, or even occupy all the resource blocks. And releasing the resources when the resource request SCI is received and the resources need to be released so as to ensure that other UE can acquire the needed resources.

Of course, in a possible implementation manner of the present disclosure, the occupied resource blocks are part or all of the resource blocks except the reserved reception slot.

S240: responding to the received resource request SCI, and performing corresponding resource processing according to the resource request SCI.

In a possible implementation manner of the present disclosure, performing corresponding resource processing according to the resource request SCI may include:

Specifically, in some possible implementation manners of the present disclosure, the specific released quantity or proportion of the currently occupied resource block may be determined according to the size of the resource required by the UE sending the resource request SCI and the size of the resource occupied by the current service. For example, the size of the resource required by the UE sending the resource request SCI only needs 20% of the size of the resource occupied by the current service, and then 20% of the resource block occupied currently can be released.

In other possible implementations of the present disclosure, the specific released amount or ratio of the currently occupied resource block may also be determined by combining the service priority. For example, the service priority of the UE requesting to release the resource is two levels higher than the current service or the highest priority is used, such as emergency call, etc., then the UE requested to release the resource may also directly release all the currently occupied resource blocks.

Specifically, in a possible implementation manner of the present disclosure, whether to release the resource may be determined according to a service priority corresponding to the SCI of the resource request. Specifically, whether the resource needs to be released may be determined according to a relationship between a service priority of the SCI of the resource request and a priority of the current service.

For example, in a possible implementation manner of the present disclosure, the manner of whether resources need to be released may be:

if the service priority corresponding to the SCI is higher than or equal to the service priority of the current service, determining that the resource needs to be released;

Of course, the above determination method is only one of many implementation manners, and the determination method may be specifically selected according to actual requirements, for example, the service priority corresponding to the resource request SCI is higher than the service priority of the current service by two levels, so as to determine that the resource needs to be released.

In a specific application scenario, for example, the current service is a real-time call service between UEs, and continuous real-time calls are required, so that the UEs can preempt a large number of continuous available resource blocks. However, if the service corresponding to the received resource request SCI is an emergency call and the service priority is higher than the current real-time call service, the UE determines to release the resource. However, if the service corresponding to the received resource request SCI is a transmission service of a common file and the priority is lower than that of the current real-time call service, the UE determines not to release the resource or releases a small amount of resource.

The method for releasing the resources may be to make the released resources return to an idle state, and other UEs sense and acquire the resources by themselves. Or the resources can be handed over to the UE sending the resource request SCI in a targeted manner.

In a possible implementation manner of the present disclosure, it is determined whether resources need to be released according to the resource request SCI, and if it is determined that resources do not need to be released, the request of the sending end is rejected by sending a response SCI. Specifically, the response SCI may include a reason for rejection, which may be that its service priority is higher.

Specifically, in a possible implementation manner of the present disclosure, the resource request SCI includes a period and a size of a resource requirement, and correspondingly, the releasing of a part or all of the currently occupied resource blocks may include:

and releasing resource blocks meeting or partially meeting the resource requirements according to the period and the size of the resource requirements, and indicating released resources by sending a response SCI of the resource request SCI, wherein the response SCI comprises information of the released resource blocks and identification information of a release end.

Specifically, the period and the size of the resource demand may be determined by the sending end of the resource request SCI according to the actual service demand, for example, the period of the resource demand of the sending end may determine which resource block or resource blocks in which periods are specifically needed according to the service delay condition, and may determine how many resource blocks are needed according to the size of the service volume. And the UE requested to release the resource may release the matched resource block according to the period and size of the resource requirement. Of course, only the resource blocks that are partially matched with the period and size of the resource demand may be released, which may be specifically determined according to the priority of the peer UE requesting the resource to initiate the service, for example, if the priority of the peer UE is lower than that of the requested UE, the requested UE may also only release a part of resources in a predetermined ratio, such as 20%, 50%, 80%, and the like, of the period and size corresponding to the resource demand, or may not release the resources.

In one possible implementation manner of the present disclosure, the method may further include:

s250: and sending a resource indication SCI to other user equipment in a resource pool of the user equipment, wherein the resource indication SCI at least comprises the identification information, the resource occupation information and the current service information of the user equipment.

Correspondingly, other user equipment can acquire the resource occupation and the service condition thereof by detecting the resource indication SCI of the user equipment, thereby determining whether to request the user equipment to release the resource.

Fig. 4 is a flowchart illustrating a radio resource occupying method according to still another implementation manner of the present disclosure. Specifically, the method may be used for a user equipment that needs to acquire radio resources, and the method may include:

s310: and sending the resource request SCI to part or all of other user equipment in the resource pool.

Wherein, the resource request SCI is used for requesting other user equipment to release resources. Any one or more of the following information may be included in the resource request SCI: the required resource period, size, service priority, which UE is expected to release resources.

In a possible implementation manner of the present disclosure, the sending a resource request SCI to some or all of the other user equipments in the resource pool may include:

s311: and detecting the resource indication SCI sent by other user equipment in the resource pool.

Specifically, the resource indication SCI may at least include service priority, and the UE to be communicated sends a resource release request to the UE that is performing SL communication and whose service is not higher than that of the UE that wants to initiate the service.

S312: and selecting the target user equipment according to the resource indication SCI.

In a possible implementation manner of the present disclosure, a UE whose SCI satisfies a predetermined condition may be selected as the target UE. The target UE refers to a selected UE that can release resources. The target UE may be part or all of a resource pool.

In a possible implementation manner of the present disclosure, specifically, the resource indication SCI includes a service priority and identification information of a UE corresponding to the resource indication SCI, and a user equipment with a service priority meeting a predetermined condition may be selected as the target UE. Specifically, for example, a UE with a service priority not higher than the service priority of the service to be initiated may be selected as the target UE. Or selecting UE with the service priority lower than the service priority of the service to be initiated as the target UE. Specifically, the condition for selecting the target UE may be determined according to actual requirements, which is not limited by the present disclosure.

S313: and sending a resource request SCI for requesting to release the resource to the target user equipment.

In some possible implementation manners of the present disclosure, the resource request SCI may include any one or more of user equipment identification information, service information to be initiated, and resource information to be acquired.

S320: and acquiring part or all of the resource blocks released by the other users.

In a possible implementation manner of the present disclosure, part or all of the resource blocks released by the other users may be obtained by:

and responding to the response SCI of the received resource request SCI which agrees to release the resources, and acquiring and occupying resource blocks released by other user equipment according to the response SCI. Specifically, the response SCI may include: granted, partially granted, and released resources. The UE may acquire and occupy resources according to the response SCI.

In another possible implementation manner of the present disclosure, if other UEs do not send a response SCI and only return occupied resources to an idle state, the UE may also obtain part or all of resource blocks released by the other UEs in the following manner:

and acquiring and occupying part or all of resource blocks released by other user equipment by adopting the SPS based on the perception semi-permanent scheduling. That is, the SPS is scheduled semi-permanently based on sensing, and the released resource blocks are acquired by itself, and of course, how many resource blocks are occupied can be determined according to actual service requirements.
