Description

Resource allocation method, device and system, UE and base station

Technical field

The present disclosure relates to the field of communications, and relates to a resource configuration method, apparatus, and system, a UE, and a base station.

Background technique

With the development of mobile communication technologies and the increasing diversification of communication needs, for example, public security, car networking, on-site command, social networking, electronic payment, local advertising and other applications are receiving more and more attention. Typical device-to-device communication applications, such as D2D (Device-to-Device) and V2X (Vehicle-to-Everything), represent a new direction for future communication technologies.

The D2D technology can work in multiple scenarios such as network coverage, partial network coverage, and no coverage. It allows multiple D2D user equipments (D2D User Equipment, D2D UE) to directly discover or directly communicate. The application of D2D technology can reduce the burden of cellular networks, reduce the battery power consumption of user equipment, increase the data rate, and improve the robustness of the network infrastructure, which satisfies the requirements of high data rate services and proximity services, and also Support direct communication under no network coverage scenarios to meet special communication needs such as public safety.

Vehicle networking communication is an advanced wireless communication technology that enables real-time information interaction between vehicles, vehicles, roadside infrastructure, vehicles and pedestrians, and informs each other's current status (including vehicle position, speed, acceleration, driving). Paths, etc., and known road environment information, collaboratively aware of road hazard conditions, timely provide a variety of collision warning information to prevent road traffic safety accidents. The modes of car networking communication can be divided into several categories: Vehicle-to-Vehicle Communication (V2V), Vehicle-to-Pedestrian Communications (V2P), and vehicle and network infrastructure. Communication-to-Infrastructure Communications (V2I for short), and Vehicle-to-Network Communications (V2N) communication. The above-mentioned vehicle networking communication mode can also be collectively referred to as Vehicle-to-Everything Communications (V2X for short).

D2D communication, V2X communication, or direct communication between other devices, usually supports two communication modes: mode one, base station scheduling based communication (called Mode1); mode two, user equipment UE (User Equipment, UE for short) autonomous Select the communication of the resource (called Mode2). For mode 1, the base station can implement orthogonal configuration of resources for UEs in the cell, but implement spatial multiplexing of resources, such as different UEs use the same time-frequency resources for D2D or V2X communication, or implement flexible broadcast of V2X messages. Regional coverage is not supported by related technologies. For mode 2, the UE selects resources autonomously. Because there is no unified management of the central node, resource conflicts are easy to occur. For example, two UEs in the effective communication range use the same time-frequency resource, so that the receiving UE cannot correctly receive the data. . Therefore, the communication system between the device and the device needs to further enhance the resource selection or configuration method to support the above communication requirements.

In view of the related art, the problem of poor resource allocation when the device communicates with the device has not yet provided an effective solution.

The provider of the current geographic location information of the user equipment may be the user equipment itself, or the current geographical location information of the user equipment detected by other network entities or devices.

In this embodiment, the wireless communication resource block may be a resource block for one user equipment, or may be a resource pool for shared use by multiple user equipments.

It should be noted that the wireless communication resource block herein is a logical wireless communication resource block, which is collectively referred to as a wireless communication resource block for convenience of description, and one wireless communication resource block may be composed of one or more physical wireless communication resource blocks.

Optionally, the wireless communication resource block is a time-frequency resource combination used for communication by the user equipment, where the time-frequency resource combination corresponds to at least one basic unit in the time domain and a preset bandwidth on the frequency domain. A radio communication resource block that the user equipment is set to communicate can be understood as a time-frequency resource (combination) that needs to be allocated to the UE for data transmission, reception, or information interaction with other devices, and the time-frequency resource can be one or more in the time domain. A basic unit and a piece of bandwidth on the frequency domain.

In an optional embodiment, the first mapping relationship between the preset geographic location information and the preset wireless communication resource block is determined; and the wireless communication resource used by the UE for communication is determined according to the first mapping relationship and the current geographic location information of the user equipment UE. The block solves the problem that the resource configuration is poorly effective when the device and the device communicate in the related art, and further allocates resources according to the current geographical location information of the UE, thereby realizing the spatial multiplexing gain of the wireless resource and reducing the resource. The interference problem caused by the conflict has achieved the technical effect of improving the utilization efficiency of resources.

In this optional embodiment, there is a certain mapping relationship between the geographic location information and the logical geographic unit, and the logical geographic unit and the wireless communication resource block also have a certain mapping relationship, and then can be determined according to the above two mapping relationships. Correspondence between geographic location information and wireless communication resource blocks. The second mapping relationship and the third mapping relationship may be set or preset by higher layer signaling. The mapping between the geographic location information and the wireless communication resource block can be effectively established by the above two mapping relationships.

Optionally, determining the second mapping relationship between the preset geographic location information and the preset logical geographic unit includes: dividing the geographic region into equally spaced regional blocks according to two or three dimensions; establishing the regional block and the preset logical geographic unit. A second mapping relationship between each region block corresponding to a preset logical geographic unit.

In this alternative embodiment, the geographical area (within the target range) is divided into equally spaced small blocks in two or three dimensions, and the geographically small blocks correspond to the logical geographic units one by one, and each logical geographic unit corresponds to A wireless communication time-frequency resource block. The different logical geographic units may correspond to the same resource block (the wireless communication time-frequency resource block or the wireless communication resource block is simply referred to as a resource block).

The following takes the vehicle network communication as an example to explain the establishment of the mapping relationship between the geographical location information and the resource block.

The location information of the User Equipment (UE) is represented by longitude and dimensional two-dimensional coordinates (x, y). The origin of the coordinates is the longitude of the Earth and the origin of the dimension, or is configured by high-level signaling, or pre-configured. The moving direction angle of the vehicle is θ (in units of radians or angles), indicating the angle between the moving direction and the reference coordinate axis. The reference coordinate axis may be a warp or a weft, or other straight lines at a certain angle with the warp and weft.

The target geographic area is divided into two-dimensional or three-dimensional area blocks of preset size, and its central coordinate is (xi, yi), wherein the length and width of the area block are respectively a and b, and a represents the geographical area along the X. The length of the direction, b represents the length of the geographic area in the Y direction. Of course, a and b may also represent a length in the direction of the angle Φ from X and Y. Where a and b can be configured or pre-configured by higher layer signaling, and a and b can be the same or different.

It should be noted that the division rules of the geographic area may be predefined or configured by higher layer signaling. For example, the coordinate origin is used as a reference point and is divided according to the geographic area size.

The geographic area block is mapped onto the logical geographic unit Gi, and the coordinates of the logical geographic unit Gi are (pi, qi). Each logical geographic unit corresponds to one resource block. Logical geographic units Gi corresponding to different geographic regions may reuse the same resource blocks. as shown in picture 2.

It should be noted that, according to the central coordinates (xi, yi) of the regional block in the target geographical area and the length and width of the regional block, The coordinates (pi, qi) of the logical geographic unit Gi, pi is the ratio of the abscissa of the central coordinate of the regional block to the length of the regional block, and qi is the ratio of the ordinate of the central coordinate of the regional block to the width of the regional block, and the calculation formula Is: pi=floor(xi/a), qi=floor(yi/b), or pi=ceil(xi/a), qi=ceil(yi/b). Among them, the floor() function is rounded down, the ceil() function is rounded up, and the rounding method is selected according to actual experience, and no limitation is made here.

All lanes of a road can share a V2X communication resource pool, and can further divide resource pools according to vehicle movement direction or lane information. For example, a road and a resource pool map, one road corresponds to one or a group of resource pools; a lane direction is mapped to a resource pool, and a lane in a driving direction corresponds to one or a group of resource pools. For convenience of explanation, it is assumed here that one road shares a resource pool, and the number of orthogonal resource blocks available for selection by the UE is N. The resource block is a set of wireless communication time-frequency resources, and can be used to carry data or control information sent by the UE. The resource pool is divided according to the size of the preset resource block to obtain multiple resource blocks. A resource pool may be considered as a radio resource shared by a plurality of UEs including a period of time in the time domain and a period of bandwidth on the frequency domain.

Each logical geographic unit Gi can be mapped to a resource block Ri in the resource pool by a preset rule, as shown in FIG. Figure 4 provides a schematic diagram of a mapping rule between logical geographic units and resource blocks, as follows:

Determine the resource group size as GN. For example, when a resource is grouped, the resource block index is a group of 5 behaviors, then GN=5. The GN may be determined according to the number N of resource blocks in the resource pool, optionally GN=floor(sqrt(N)), or GN=ceil(sqrt(N)). In addition, the GN can also be directly signaled or pre-configured by higher layers.

The logical geographic unit groups the rows according to the resource group size GN, that is, one set per GN behavior. The resource block index of the initial row (first row, qi=0) in the logical geographic unit may be determined by the coordinates (pi, qi) of the logical geographic unit Gi, such as R0=mod(pi, N); or by adding a fixed offset, For example, R0=mod(pi+Δ, N), where Δ is an integer. In the same group, the j-th row resource block index can be obtained by the resource block index of the previous row (j-1th row) plus a fixed offset, such as R _j = mod(R _j-1 + GN, N), for example, a fixed offset Move to GN; between different groups, the current group is compared with the previous group, the resource block index is fixed offset, such as R _j = mod(R _j-GN + Goffset, N), where Goffset is an integer, such as Goffset =floor(qi/GN)*m+n, m, n are constants, m, n can be configured by high-level signaling, pre-configured or calculated according to preset rules.

A preferred formula is as follows:

Ri=mod((mod(pi,N)+mod(qi,GN)*GN*C+Goffset),N);

Where N is the number of resource blocks available in the current resource pool; GN=floor(sqrt(N)) or GN=ceil(sqrt(N)), indicating the resource packet size; C is an integer, indicating the inter-row offset factor; Goffset =floor(qi/GN)*m+n or Goffset =ceil(qi/GN)*m+n, indicating the offset between groups, m and n are integers, indicating the inter-group offset factor; mod(x, y) is the remainder of x divided by y; floor(x) Indicates that x is rounded down; ceil(x) means that x is rounded up.

It should be noted that the above method is also applicable to the case where the row and column are interchanged.

Optionally, determining, according to the first mapping relationship and the current geographic location information of the user equipment UE, that the radio communication resource block used by the UE for communication comprises: determining, according to the first mapping relationship and current geographic location information of the user equipment UE, that the UE is used for At least one of the location and index of the wireless communication resource block of the communication.

The location or index of the wireless communication resource block is used to identify different blocks of wireless communication resources. For example, based on the unified timing reference, at a specific time point, the UE maps the logical geographic location unit index (pi, qi) according to its own geographic location coordinates (xi, yi), and then according to the high layer signaling or the pre-configured mapping relationship. Obtaining a resource selection formula and related parameters, and calculating a position or an index Ri of the usable resource block according to the resource selection formula and related parameters.

Optionally, after determining, according to the first mapping relationship and the current geographic location information of the user equipment UE, the at least one of the location and the index of the wireless communication resource block used by the UE, the method further includes: the UE is in the location and the index. Communication is performed on the wireless communication resource block corresponding to the at least one type of information.

In this embodiment, the UE may perform communication on the wireless communication resource block corresponding to the at least one information in the location and the index according to at least one of the location and the index of the wireless communication resource block determined by the UE; or, the UE also At least one of a location and an index of a radio communication resource block for the UE communication determined by the base station may be received, and the UE performs communication on the radio communication resource block corresponding to the at least one of the location and the index.

Optionally, the user equipment continuously communicates on the wireless communication resource block corresponding to the at least one of the location and the index, until the user equipment reselects the wireless communication resource block.

In this embodiment, when the user equipment is in a mobile state, the geographic location of the user equipment changes, and the wireless communication resource block corresponding to the at least one information in the location and the index is continuously used for communication in a certain geographical area. In an actual application scenario, the UE continuously uses the current resource block, that is, the UE periodically uses the time-frequency resource or frequency of the wireless communication resource block, for example, the use of the current communication resource block every 100 milliseconds, because the time The interval is small, and the period is short. Here, the user equipment can be regarded as continuing to communicate on the wireless communication resource block corresponding to at least one type of information in the location and the index, but when the geographic location of the user changes, the wireless communication resource corresponding to the geographical location is caused. After the location and index of the block change, the user equipment stops communicating on the current wireless communication resource block until the user equipment reselects the wireless communication resource block.

Optionally, the user equipment reselecting the wireless communication resource block includes: determining, by the UE, at least one of a location and an index of the wireless communication resource block corresponding to the detected current geographic location information every predetermined time period, and The re-determined location communicates with the wireless communication resource block corresponding to at least one of the information in the index.
