Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on and claims the priority of Chinese patent application with application number 201710184771.4 and application date March 24, 2017. The entire contents of the Chinese patent application are hereby introduced into this application as a reference. Technical Field

[0003] The present invention relates to wireless communication technology, and in particular to a resource allocation method, device and storage medium. Background Art

[0004] In recent years, short-range communications, such as device-to-device (D2D) and vehicle-to-everything (V2X), have received increasing attention and research. It can be applied to public safety, vehicle networking, on-site command, social networking, electronic payment, local advertising, gaming and entertainment, etc.

[0005] D2D technology can work in a variety of scenarios such as network coverage, partial network coverage and no coverage, allowing multiple user equipment supporting D2D functions, namely D2D User Equipment (D2D UE), to conduct direct discovery or direct communication. The application of D2D technology can reduce the burden on cellular networks, reduce the battery power consumption of user equipment, increase data rates, and improve the robustness of network infrastructure, which can well meet the requirements of high data rate services and proximity services, and also supports direct communication in scenarios without network coverage, which can meet special communication needs such as public safety.

[0006] IoV communication is to achieve real-time information exchange between vehicles, vehicles and roadside infrastructure, vehicles and pedestrians through advanced wireless communication technology, inform each other of the current status (including vehicle location, speed, acceleration, driving path, etc.) and the road environment information obtained, collaborate to perceive road danger conditions, and provide a variety of collision warning information in a timely manner to prevent road traffic safety accidents. IoV communication modes can be specifically divided into several categories: vehicle-to-vehicle communication (V2V), vehicle-to-pedestrian communication (V2P), vehicle-to-network infrastructure communication (V2I), and vehicle-to-network (V2N) communication. The above-mentioned IoV communication modes can also be collectively referred to as vehicle-to-everything communications (V2X).

[0007] D2D communication, V2X communication, or direct communication between other devices usually supports two communication modes: Mode 1, communication based on base station scheduling (called Mode 1 in D2D and Mode 3 in V2X); Mode 2, communication in which UE autonomously selects resources (called Mode 2 in D2D and Mode 4 in V2X). Usually, different communication modes will allocate different transmission resource pools, and UEs in each communication mode only use the transmission resource pool allocated to them to prevent resource conflicts caused by the differences in the two resource selection modes. However, since the number of UEs in different communication modes and the traffic volume cannot be predicted, this division method will significantly reduce the efficiency of resource utilization.

[0068] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0069] The steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. Also, although a logical sequence is shown in the flowchart, in some cases, the steps shown or described can be performed in a sequence different from that shown here.

[0070] The embodiment of the present invention provides a resource allocation method, which allocates a shared resource pool or resource area to a mode 1 UE and a mode 2 UE, thereby improving resource utilization efficiency. When a mode 1 UE and a mode 2 UE share resources, the mode 2 UE can autonomously select resources according to its resource selection mechanism. The mode 1 UE requires a base station to allocate resources to it.

[0071] like Figure 1As shown, an embodiment of the present invention provides a resource allocation method, including:

[0072] Step S102, the base station configures or pre-configures a shared resource pool or a shared resource area for mode 1 user equipment and mode 2 user equipment, and a dedicated resource pool or a dedicated resource area only for mode 1 user equipment for the user equipment;

[0073] Step S104, after receiving a resource request from the user equipment, allocating resources to the user equipment from the shared resource pool or the shared resource area or the dedicated resource pool or the dedicated resource area according to the available resources in the shared resource pool or the shared resource area.

[0074] The available resource information of the shared resource pool or shared resource area refers to an available resource or a set of available resources that meet the delay and interference requirements and are measured by the UE on the shared resource pool or shared resource area according to pre-configured parameters or indication parameters of the base station.

[0075] Mode 1 refers to a communication mode based on base station scheduling (called Mode 1 in D2D and Mode 3 in V2X); Mode 2 refers to a communication mode in which the UE autonomously selects resources (called Mode 2 in D2D and Mode 4 in V2X).

[0076] The mode 1 user equipment dedicated resource area refers to a time-frequency resource set consisting of part of the time domain and frequency domain resources in the shared resource pool, which is only used by mode 1 UE and cannot be used by mode 2 UE.

[0077] In this embodiment, the execution entity of step S102 and step S104 may be a base station, wherein the base station may be a traditional base station, a base station type roadside unit, or other network entities with resource scheduling functions.

[0078] In this embodiment, the shared resource pool or shared resource area can be shared by mode 1 UE and mode 2 UE, and can also be configured as a mode 2 resource pool for legacy UE (other versions of UE that do not support the method of the present invention).

[0079] There are two options for resource configuration: Figure 2 and Figure 3 shown.

[0080] Solution 1

[0081] like Figure 2As shown, a shared resource pool 21 and a dedicated resource pool 22 for mode 1 UE are configured. In this configuration, the shared resource pool 21 and the dedicated resource pool 22 for mode 1 UE can be configured separately through high-layer signaling. The resources of the shared resource pool 21 and the dedicated resource pool 22 for mode 1 UE can be continuous or separated by some time-frequency resources.

[0082] Solution 2

[0083] like Figure 3 As shown, a transmission resource pool 30 is configured, and the transmission resource pool 30 includes a shared resource area 31 and a dedicated resource area 32 for mode 1 UE. The transmission resource pool 30 can be configured through an RRC message, and at the same time, it will indicate that part of the resources in the frequency domain range or time domain range are the dedicated resource area 32 for mode 1 UE, and the rest are the shared resource area 31; or indicate that part of the resources in the frequency domain range or time domain range are the shared resource area 31, and the rest are the dedicated resource area 32 for mode 1 UE. In addition to the original resource pool configuration parameters, other indication parameters include but are not limited to: resource pool type, frequency domain starting position or index of the dedicated resource area for mode 1 UE, frequency domain ending position or index of the dedicated resource area for mode 1 UE, time domain starting position or index of the dedicated resource area for mode 1 UE, time domain ending position or index of the dedicated resource area for mode 1 UE, time domain position bitmap or pattern of the dedicated resource area for mode 1 UE, and frequency domain position bitmap or pattern of the dedicated resource area for mode 1. In one embodiment, the dedicated resource area for mode one UE can be configured as a receiving resource pool for legacy mode two UE, or a transmitting resource pool for legacy mode one UE; the shared resource area can be configured as a transmitting resource pool or a receiving resource pool for legacy mode two UE.

[0084] In an optional embodiment of the present invention, allocating resources to the user equipment from the shared resource pool or the shared resource area or the dedicated resource pool or the dedicated resource area according to the available resources in the shared resource pool or the shared resource area includes:

[0085] If the base station has learned that the shared resource pool or the shared resource area has available resources that meet the needs of the user equipment, resources are allocated to the user equipment in the shared resource pool or the shared resource area.

[0086] If the base station does not have available resource information of the shared resource pool or the shared resource area or the available resources of the shared resource pool or the shared resource area known to the base station do not meet the resource request of the user equipment, resources are allocated to the user equipment in the dedicated resource pool or dedicated resource area of ​​the user equipment in mode 1. In one embodiment, the signaling of the resources allocated to the UE by the base station includes at least one of: an index of the sending resource pool where the current resource is located, and a sending resource pool list.

[0087] In an optional embodiment of the present invention, after receiving the resource request of the user equipment, if the base station does not have the available resource information of the shared resource pool or the shared resource area, or the available resources of the shared resource pool or the shared resource area known to the base station do not meet the resource request of the user equipment, the user equipment or other user equipment is instructing to measure the shared resource pool or shared resource area and report the measured one or a group of available resources.

[0088] In an optional embodiment of the present invention, the base station instructs or preconfigures the user equipment or other user equipment to send scheduling indication information (SA) or sidelink control information (SCI) on the reported available resources, and the SA indicates that the reported available resources have been used. The SA indicates that these resources have been used, which means that the resource location of the initial transmission and retransmission of data indicated in the SA includes the location of the reported available resources. Optionally, the priority carried in the SA is the highest level, or is a priority greater than or equal to a priority threshold.

[0089] In an optional embodiment of the present invention, the mode 2 UE selects resources only from resources outside the mode 1 dedicated resource region, that is, selects resources from resources in a shared resource pool or a shared resource region.

[0090] In one implementation, resources (shared resource pool or shared resource area) outside the mode 1 dedicated resource area may be configured as a transmission resource pool or a reception resource pool of a legacy mode 2 UE.

[0091] An embodiment of the present invention provides a resource allocation method, including:

[0092] The user equipment receives the configuration information sent by the base station, or determines the resource pool configuration according to the pre-configuration information;

[0093] The mode 1 user equipment obtains resource allocation information from the base station, and sends information on the resources indicated by the resource allocation information.

[0094] In an optional embodiment of the present invention, the resource indicated by the resource allocation information is one of the following: resources in the shared resource pool or shared resource area, or resources in the dedicated resource pool or dedicated resource area of ​​the mode one user equipment.

[0095] In an optional embodiment of the present invention, if the resources indicated by the resource allocation information are resources in a dedicated resource pool or a dedicated resource area of ​​a mode 1 user equipment, or after the user equipment receives an instruction sent by the base station to measure the available resources in the shared resource pool or the shared resource area, the user equipment measures and reports one or a group of available resources in the shared resource pool or the shared resource area to the base station.

[0096] In an optional embodiment of the present invention, before or after the user equipment reports the one or a group of available resources to the base station, an SA is sent on the one or a group of available resources, and the SA indicates that the one or a group of available resources have been used. The sending of SA to indicate that these resources have been used refers to sending one or more SAs, wherein the indicated data resource locations are the locations of these resources. In one embodiment, data is not actually sent on these resources, or data is sent. In another embodiment, the priority information carried in the SA can be set to the highest priority, or a priority higher than a preset priority threshold, and the priority threshold can be configured or pre-configured by the base station. For example, if the priority threshold is set to 4, the priority information carried in the SA can be set to other priorities higher than 4.

[0097] The following takes vehicle-to-everything (V2X) communication as an example to further illustrate the above-mentioned resource pool sharing method through several preferred embodiments.

[0098] Embodiment 1

[0099] This embodiment provides a resource allocation method, the basic process is as follows Figure 4 As shown, the detailed steps include:

[0100] Step 401, configure or preconfigure a resource pool, the resource pool solution is Figure 2 Solution 1 shown includes a shared resource pool and a mode 1 UE dedicated resource pool.

[0101] Step 402: The base station receives a resource request from the UE.

[0102] It should be noted that the UE here is a mode 1 UE, and the mode 2 UE independently selects resources and does not need the base station to schedule resources.

[0103] Step 403: If the information obtained by the base station does not contain idle resource information on the shared resource pool or the known idle resource information cannot meet the resource configuration requirements of the current UE, the base station allocates resources to the UE in the mode 1 UE dedicated resource pool and notifies the UE of the allocated resources.

[0104] In one embodiment, the base station may notify the UE via downlink control information indication DCI, wherein some parameters may be notified via RRC signaling.

[0105] Among them, at least one of the information is carried when notifying the UE: the location and size information of the resource authorized for use, the offset between the time domain starting position of the resource and the current DCI time domain position, the sending resource pool index, the resource pool type, and the sending resource pool list.

[0106] The resources allocated by the base station to the UE in the mode 1 UE dedicated resource pool may be resources used for one transmission or a group of resources for multiple periods of SPS transmission.

[0107] In one implementation, the base station instructs the UE or other UEs to measure and report available resource information in the shared resource pool, wherein the other UEs are UEs in an RRC connected state.

[0108] In another embodiment, the UE may be configured or pre-configured to send an SA in the reported available resources to indicate that the available resources have been used.

[0109] Step 404: The base station receives available resource information of the shared resource pool reported by the UE or other UEs.

[0110] Step 405: The base station reallocates available resources in the shared resource pool to the UE according to the available resource information of the shared resource pool.

[0111] The shared resource pool can be shared by mode 1 UE, mode 2 UE, and legacy mode 2 UE. The mode 1 dedicated resource pool can be shared by mode 1 UE or legacy mode 1 UE, and can also be configured as a receiving resource pool for mode 2 UE.

[0112] In this embodiment, after the resource pool sharing process described above, the base station can allocate resources that meet the requirements to the mode 1 UE without affecting the normal use of the mode 2 UE on the shared resource pool, thereby improving the resource utilization efficiency of the resource pool.

[0113] Embodiment 2

[0114] This embodiment provides a resource allocation method, the basic process is as follows Figure 5 As shown, the detailed steps include:

[0115] Step 501, configure or preconfigure a resource pool, the resource pool solution is Figure 2 The scheme 1 shown includes a shared resource pool and a mode 1 dedicated resource pool.

[0116] Step 502: The base station receives a resource request message from the UE.

[0117] Step 503: If the known idle resource information on the shared resource pool can meet the resource allocation of the current UE, or it is known that the resources occupied by other modes in the shared resource pool will be or have been released and can meet the resource allocation of the current UE, the available resources in the shared resource pool are allocated to the UE for use.

[0118] The available resource information of the shared resource pool is obtained through the available resource information on the shared resource pool reported by the currently scheduled UE or other UEs.

[0119] The shared resource pool can be shared by mode 1 UE, mode 2 UE, and legacy mode 2 UE. The mode 1 dedicated resource pool can be shared by mode 1 UE or legacy mode 1 UE, and can also be configured as a receiving resource pool for mode 2 UE.

[0120] In this embodiment, after the resource pool sharing process described above, the base station can allocate resources that meet the requirements to the mode 1 UE without affecting the normal use of the mode 2 UE on the shared resource pool, thereby improving the resource utilization efficiency of the resource pool.

[0121] Embodiment 3

[0122] This embodiment provides a resource allocation method, the basic process is as follows Figure 6 As shown, the detailed steps include:

[0123] Step 601, configure or preconfigure a resource pool, the resource pool solution is Figure 3 In the second scheme shown, the sending resource pool includes a mode one dedicated resource area and a shared resource area.

[0124] Step 602: The base station receives a resource request message from the UE.

[0125] Step 603, the base station determines whether there are available resources that meet the requirements in the shared resource area for use by the UE. If yes, go to step 607, otherwise, go to step 604;

[0126] Step 604: If the base station does not have available resource information in the shared resource area, or the known idle resources cannot satisfy the resource allocation of the current UE, resources are allocated in the dedicated resource area of ​​mode 1, and the UE is notified to use them. In one embodiment, the UE is instructed to measure and report the available resource information in the shared resource area; or, the UE is configured or pre-configured to send SA on the reported available resources, and indicates that these available resources have been used.

[0127] Step 605: The base station receives available resource information of the shared resource area reported by the UE or other UEs.

[0128] The available resource information may be a piece of resource location information or a group of resource location information.

[0129] Step 606: the base station reallocates resources to the UE from available resources in the shared resource area, and the process ends.

[0130] Step 607: the base station allocates resources to the UE from available resources in the shared resource area, and the process ends.

[0131] The shared resource area can be shared by mode 1 UE and mode 2 UE, and can also be used as a transmit resource pool for legacy mode 2 UE. The mode 1 dedicated resource area can be shared by mode 1 UE and legacy mode 1 UE, and can be configured as a receive resource pool for legacy mode 2 UE.

[0132] In this embodiment, after the resource pool sharing process described above, the base station can allocate resources that meet the requirements to the mode 1 UE without affecting the shared use of the shared resource pool with the mode 2 UE, thereby improving the resource utilization efficiency of the resource pool.
