Description

Resource selection method and device

Technical Field

The disclosure relates to the field of communication, and in particular relates to a resource selection method and device.

Background

The Internet of vehicles refers to a large system network for wireless communication and information exchange between vehicles-X (X: vehicles, roads, pedestrians, the Internet, etc.) according to the agreed communication protocol and data interaction standard. The vehicle can obtain running safety, traffic efficiency and convenience or entertainment information through the communication of the internet of vehicles. Classified from objects of wireless communication, internet of vehicles communication includes three different types: vehicle-to-vehicle communication (Vehicle to Vehicle, V2V for short), vehicle-to-roadside equipment communication (Vehicle to Infrastructure, V2I for short), and vehicle-to-pedestrian communication (Vehicle to Pedestrian, V2P for short), collectively referred to as V2X communication.

In V2X communication research based on LTE (Long Term Evolution ) organized by 3GPP (3 rd Generation Partnership Project), a V2X communication method based on a side link (sidlink) between User equipments (User Equipment, abbreviated as UE) is one of modes of implementing V2X standards, that is, service data is directly transmitted to a target User Equipment through an air interface by a source User Equipment without forwarding through a base station and a core network, as shown in fig. 1, such a V2X communication mode is abbreviated as PC5-based V2X communication.

The resource pools used by the current V2X communication UE are determined through configuration, the sizes of the resource pools used by different types of UE are fixed and independent, and the resource pools cannot be changed according to the change of the UE on the resource demand. In some scenarios, the problem of resource conflict or resource waste between V2X signals is easy to occur.

However, in the related art, an effective solution has not been proposed for the problem that the user terminal cannot fully utilize the radio resources of the resource pool.

Taking the operation on a mobile terminal as an example, fig. 2 is a block diagram of a hardware structure of a mobile terminal of a resource selection method according to an embodiment of the present disclosure. As shown in fig. 2, the mobile terminal 10 may include one or more (only one is shown in fig. 2) processors 102 (the processors 102 may include, but are not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmission device 106 for communication functions. It will be appreciated by those of ordinary skill in the art that the configuration shown in fig. 2 is merely illustrative and is not intended to limit the configuration of the electronic device described above. For example, the mobile terminal 10 may also include more or fewer components than shown in FIG. 2 or have a different configuration than shown in FIG. 2.

The memory 104 may be used to store software programs and modules of application software, such as program instructions/modules corresponding to the resource selection method in the embodiments of the present disclosure, and the processor 102 executes the software programs and modules stored in the memory 104, thereby performing various functional applications and data processing, i.e., implementing the method described above.

In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC) that can connect to other network devices through a base station to communicate with the internet. In one example, the transmission device 106 may be a Radio Frequency (RF) module for communicating with the internet wirelessly.

In this embodiment, a resource selection method is provided, fig. 3 is a flowchart of resource selection according to an embodiment of the disclosure, and as shown in fig. 3, the flowchart includes the following steps:

step S302, the terminal determines the range and/or the size of the first subset of transmission resource pools and/or the second subset of transmission resource pools in the transmission resource pools, where the determining method includes at least one of the following: determining according to the received indication signaling, determining according to a monitoring result in the sending resource pool, and determining according to the indication signaling sent by the terminal; the terminal comprises: a first terminal, and/or a second terminal;

in step S304, the first terminal uses resources of the first subset of the transmission resource pool and the second terminal uses resources of the second subset of the transmission resource pool.

In this embodiment, the first terminal and the second terminal correspond to the UE of mode 3 and the UE of mode 4, respectively.

Optionally, in this embodiment, the application scenario of the resource selection method includes, but is not limited to: V2X communication, wherein V2X sidelink communication comprises two transmission modes of mode 3 based on base station scheduling resources and mode 4 based on UE contention resources, in the mode 3, the UE transmits control and data on specified resources according to base station scheduling, in the mode 4, the UE autonomously selects the control and data for resource transmission according to resource monitoring of the control and data transmitted in a transmission resource pool. In the prior art, however, the range and/or size of the transmission resource pool configured by the base station for both mode 3 and mode 4 transmission modes is fixed and independent of each other. Because of the change of the V2X scene, the number of UEs in mode 3 cannot always be matched with the transmission resource pool in mode 3, and the problem of serious transmission resource collision or resource waste is likely to occur. Also, this problem exists for mode 4 UEs, and for this technical problem, the present implementation proposes that the terminal determines, in the transmission resource pool, a range and/or a size of the first subset of the transmission resource pool and/or the second subset of the transmission resource pool, where the determining method includes at least one of: determining according to the received indication signaling, determining according to a monitoring result in the sending resource pool, and determining according to the indication signaling sent by the terminal; the terminal comprises: a first terminal, and/or a second terminal; the first terminal uses resources of a first subset of the transmit resource pool and the second terminal uses resources of a second subset of the transmit resource pool. That is, in this embodiment, the first terminal and the second terminal share the transmission resource pool, instead of the first terminal and the second terminal in the prior art selecting radio resources independently from each other, which results in resource waste, thereby solving the problem that in the related art, the user terminal cannot fully utilize the radio resources in the resource pool, and achieving the effect of improving the radio resource utilization rate.

In an alternative embodiment, the first terminal comprises a base station scheduling based terminal and the second terminal comprises a terminal that autonomously selects resources based on contention.

Optionally, determining according to the received indication signaling includes: determining according to the received system broadcast message; and/or, according to the received radio resource control layer signaling.

This embodiment is illustrated below in conjunction with alternative embodiments.

The techniques described in this embodiment are applicable to cellular wireless communication systems or networks. Common cellular wireless communication systems may be based on CDMA (Code Division Multiplexing Access, code division multiple access) technology, FDMA (Frequency Division Multiplexing Access, frequency division multiple access) technology, OFDMA (Orthogonal frequency division multiple access) technology, SC-FDMA (Single Carrier-FDMA, single Carrier frequency division multiple access) technology, and the like. For example, 3GPP (3 rd Generation Partnership Project) LTE (Long Term Evolution )/LTE-A (LTE-Advanced, long term evolution-Advanced) cellular communication system downlink (otherwise known as forward link) is based on OFDMA technology, and uplink (otherwise known as reverse link) is based on SC-FDMA multiple access technology.

In an OFDMA/SC-FDMA system, the Radio Resource (Radio Resource) used for communication is in the form of time-frequency two dimensions. For example, for an LTE/LTE-a system, the communication resources of the uplink and downlink are divided in units of radio frames (radio frames) in the time direction, each radio frame being 10ms in length and containing 10 subframes (sub-frames) of 1ms in length, each subframe including two slots (slots) of 0.5ms in length, as shown in fig. 4. And each slot may include 6 or 7 OFDM or SC-FDM symbols depending on the configuration of the Cyclic Prefix (CP).

In the frequency direction, resources are divided in units of subcarriers (subcarriers), and specifically in communication, the minimum unit of frequency domain Resource allocation is RB (Resource Block), which corresponds to one PRB (Physical RB) of a Physical Resource. One PRB contains 12 subcarriers (sub-carriers) in the frequency domain, corresponding to one slot (slot) of the time domain. The resources corresponding to one subcarrier on each OFDM/SC-FDM symbol are called Resource Elements (REs). As shown in fig. 5.

In various embodiments described in this disclosure, the same radio resource structure as LTE cellular communication is employed. By the resource selection method, the resource utilization efficiency and the transmission reliability of V2X communication can be improved.

Further description will be provided below with reference to specific examples.

Alternative embodiment one

As shown in fig. 6, in V2X communication, mode 3 UEs and mode4 UEs share a transmission resource pool, where 400 is a set of transmission resources of mode 3 UEs, 402 is a first subset of the transmission resource pool, 402 is a set of transmission resources of mode4 UEs, 401 is a second subset of the transmission resource pool, and 401 is a boundary between the two sets of transmission resources, which may be a boundary or a boundary resource region. The boundary does not contain radio resources as shown in fig. 7; the boundary resource region contains radio resources, as shown in fig. 8, and includes one or more adjacent or non-adjacent radio subframes in the time domain, and one or more subcarriers, RBs, or sub-channels in the frequency domain, where the sub-channels include one or more RBs. 403 and 404 are the limit position 1 and the limit position 2 of the boundary, respectively.

The initial position of the boundary is determined through base station configuration or pre-definition, in V2X communication, the base station schedules resources for mode 3 UE in 400, and mode 4 UE autonomously selects resources according to signal monitoring and/or signal energy detection results in 402. The Mode 3 UE measures CBR (Channel Busy Ratio: channel occupancy) in 400 and 402 and reports to the base station.

When the CBR measured in 400 by the UE in mode 3 is greater than the threshold M1 and the CBR measured in 402 is not greater than the threshold M2, the base station adjusts the position of the boundary 401 so that the range of 400 becomes larger and the range of 402 becomes smaller. Otherwise, if the UE in mode 3 reports that the CBR measured in 400 is not greater than the threshold M1 and the CBR measured in 402 is greater than the threshold M2, the base station adjusts the position of the boundary 401 so that the range of 400 becomes smaller and the range of 402 becomes larger. If the CBR measured in 400 is not greater than the threshold M1 and the CBR measured in 402 is not greater than the threshold M2, the base station does not adjust the position of the boundary 401; if the CBR measured in 400 is greater than the threshold M1 and the CBR measured in 402 is greater than the threshold M2, the base station does not adjust the position of the boundary 401 or adjusts the position of the boundary 401 based on a certain probability.

The above described change of the boundary position is performed based on the period T2. The granularity of adjustment includes sub-channel, RB, or sub-carrier, and the adjustment range of the boundary position does not exceed the range of the limit position 1 (403) and limit position 2 (404) constraints.

Alternative embodiment II

As shown in fig. 9, in V2X communication, mode 3 UE shares a transmission resource pool with mode 4 UE, 700 is a transmission resource set of mode 3 UE, which is a first subset of the transmission resource pool, 702 is a transmission resource set of mode 4 UE, which is a second subset of the transmission resource pool, 701 is a boundary resource region, and includes a certain number of radio resources, as shown in fig. 6, one or more adjacent or non-adjacent radio subframes are included in the time domain, and one or more subcarriers, RBs, or sub-channels are included in the frequency domain, where the sub-channels include one or more RBs. The embodiment is described herein with one sub-channel as a boundary resource region. 703 is a resource occupied by the UE transmitting control and/or data in

mode

3, and 704 is a resource occupied by the UE transmitting control and/or data in mode 4. 705 and 706 are the limit position 1 and the limit position 2 of the boundary resource region, respectively.

The initial position of the boundary resource region 701 is determined through base station configuration or pre-definition, in V2X communication, the base station schedules resources for mode 3 UE in 700, and mode 4 UE autonomously selects resources according to the sending result in 702.

When the number of the mode 3 UEs increases or the demand of the UEs for resources increases, the finally scheduled mode 3 UEs use the resources of the first subset 700 of the transmission resource pool, and the base station schedules the mode 3 UEs into the boundary resource region 701; when the mode 4 UE monitors that resources in the boundary resource area 701 are occupied or signal energy can be detected in the boundary resource area 701, it is determined that the mode 3 UE occupies the resources in the boundary resource area, and if it is determined that there are idle resources in the range of the adjacent boundary resource area in the second subset of the transmission resource pool according to signal monitoring or signal energy detection and the idle resources are larger than the size of the boundary resource area, the resources closest to the boundary resource area 701 in the second subset 702 of the transmission resource pool are exited, that is, the size and the range of the second subset of the transmission resource pool are reduced, and the exited resource range is the same as or larger than the size of the boundary resource area 701. If the resources occupied by the mode 3 UEs continue to increase, the location of the border resource region continues to move inside the second subset of transmission resources 702. The range of movement cannot exceed the base limit position 706, however, the manner in which the value of the base limit position 706 is determined includes: the base station is configured, or preconfigured, or predefined.

Or, the UE in mode 4 does not determine whether there are free resources in the second subset of the transmission resource pool, and if it is monitored that there are resources in the boundary resource area 701 that are occupied or that signal energy can be detected in the boundary resource area 701, the resources in the second subset of the transmission resource pool that are nearest to the boundary resource area 701 are retracted, that is, the size and the range of the second subset of the transmission resource pool are reduced, and the exiting resource range is the same as or greater than the size of the boundary resource area 701. And also corresponds to moving the location of the border resource region inside the second subset 702 of the transmit resource pool.

In contrast, when the number of UEs in mode 3 decreases or the number of radio resources required decreases, the first subset 700 of the transmission resource pool is free of idle resources, and when the number of idle resources reaches the size of the boundary resource region 701 or more, the base station performs scheduling on mode 3 to free resources adjacent to the boundary resource region 701 in the transmission resource set 700, which is the same as or larger than the size of the boundary resource region 701. When the mode 4 UE monitors that the resource with the same size or larger size that is nearest to the boundary resource region 701 in the transmission resource set 700 is idle, the UE occupies the resource of the original boundary resource region 701 when selecting the resource, and takes the resource nearest to the boundary resource region 701 that is idle in the transmission set 700 as a new boundary resource region. As a result, the size and extent of the first subset of transmission resource pools 700 is reduced, the size and extent of the second subset of transmission resource pools 702 is increased, and the boundary resource region 701 moves inside the first subset of transmission resource pools 700. If the number of mode 3 UEs or the required radio resources continue to decrease, the first subset of transmit resource pools 700 continues to decrease, the second subset of transmit resource pools 702 continues to increase, and the location of the boundary resource region continues to move inside the set of transmit resources 700. However, the range of movement cannot exceed the base limit position 705, and the manner in which the value of the base limit position 705 is determined includes: the base station is configured, or preconfigured, or predefined.

Alternatively, in this embodiment, the base station schedules the UE of mode3 to preferentially schedule the radio resources in the first subset 700 of the transmission resource pool away from the boundary resource region 701; when the number of radio resources in the first subset 700 of the transmission resource pool that are all scheduled to the UE of mode3 or the remaining free resources is lower than the threshold H1 and/or the proportion of the remaining free resources to the total resources in the first subset 700 of the transmission resource pool is lower than H2, the base station schedules the UE of mode3 to the resources within the boundary resource region 701.

In the present embodiment, the above-described operation of changing the boundary resource region is performed based on the period T3.

Alternative embodiment III

Referring to fig. 9, in V2X communication, mode3 UE shares a transmission resource pool with mode 4 UE, 700 is a transmission resource set of mode3 UE, which is a first subset of the transmission resource pool, 702 is a transmission resource set of mode 4 UE, which is a second subset of the transmission resource pool, 701 is a boundary resource region, and includes a certain number of radio resources, as shown in fig. 6, one or more adjacent or non-adjacent radio subframes are included in a time domain, and one or more subcarriers, RBs, or sub-channels are included in a frequency domain, where the sub-channels include one or more RBs. The initial position and/or size of the border resource area 701 is determined by base station configuration or pre-definition. In V2X communication, a base station schedules resources for mode3 UEs in 700, mode3 UEs indicate the type of UEs in control information, for example mode3 UEs in mode 4 UEs monitor V2X signals and/or sense signal energy based on the resources, and in 702, autonomously select resources according to the monitoring and/or sensing result.

The UE in Mode 4 monitors V2X signals in the sending sets 700 and 702, determines resources occupied by the UE in Mode 3 according to the indication content of the UE type in the control information, and determines the location of the boundary resource region according to the range where the resources occupied by the UE in Mode 3 are located.

When the UE in mode 4 monitors that the resources adjacent to the boundary resource region in the transmission resource set 700 are idle and the idle resource range is not smaller than the boundary resource region, merging the original boundary resource region into the transmission resource set 702, and taking the idle resources adjacent to the boundary resource region in the transmission resource set 700 as a new boundary resource region. The updated size and/or range of the transmission resource set 700 is the size and/or range of the transmission resource pool set 700 before updating minus the size and/or range of a boundary resource area; the updated size and/or range of the transmission resource set 702 is the size and/or range of the transmission resource pool set 702 before updating plus a boundary resource region, and the position of the boundary resource region 701 is adjusted to the side of the transmission resource pool set 700, and the adjusted granularity is the size of the boundary resource region. The boundary resource region 701 cannot be adjusted beyond the base limit position 705.

When the UE in mode 4 monitors that the UE in mode 3 occupies resources in the border resource area 701, or detects that the transmission resource set 702 has idle resources and the size of the idle resources is not smaller than the size of the border resource area 701, the UE in mode 4 vacates resources in the border resource area 701, the size of the vacated resources is not smaller than the size of the border resource area, determines that the original border resource area is the resource of the transmission resource set 700, and takes the resource in the border resource area 701 vacated in the transmission resource set 702 as a new border resource area. The updated size and/or range of the transmission resource set 700 is the size and/or range of the transmission resource pool set 700 before being updated plus a boundary resource region; the updated size and/or range of the transmission resource set 702 is the size and/or range of a border resource area subtracted from the transmission resource pool set 702 before updating, the position of the border resource area 701 is adjusted to the side of the transmission resource pool set 702, and the adjusted granularity is the size of a border resource area. The boundary resource region 701 cannot be adjusted beyond the base limit position 706.

In the present embodiment, the above-described operation of changing the boundary resource region is performed based on the period T4.

Alternative embodiment IV

As shown in fig. 10, a resource region 801 is an overlapping portion of transmission resource pools of mode 3 UEs and mode4 UEs, and is a shared transmission resource pool of mode 3 UEs and mode4 UEs; the shared transmission resource pool comprises one or more adjacent or non-adjacent wireless subframes in a time domain, one or more subcarriers, RBs or sub-channels in a frequency domain, wherein the sub-channels comprise one or more RBs. 803 is a dividing line, which divides the boundary resource area 801 into a first subset 804 of transmission resource pool and a second subset 805 of transmission resource pool, and the initial position of the dividing line is determined by base station configuration or pre-definition. 800 is a set of transmission resources of mode 3 UE, and 802 is a set of transmission resources of mode4 UE.

In V2X communication, a base station schedules resources in a first subset of a transmission resource pool for a UE in a mode 3, where the first subset of the transmission resource pool includes 804, and the UE in the mode 3 indicates a type of the UE, such as mode 3, in control information; the mode4 UE autonomously selects resources in a second subset of the transmit resource pool based on the resource listening V2X signal and/or the perceived signal energy, the second subset of the transmit resource pool comprising 805.

The UE in Mode 4 monitors the V2X signal in the shared transmission resource pool 801, determines the resources occupied by the UE in Mode3 according to the indication content of the UE type in the control information, and determines the position of the dividing line 803 according to the range where the resources occupied by the UE in Mode3 are located.

When the UE in the mode 4 monitors that part or all of the resources adjacent to the boundary line in the mode 804 are idle, the position of the boundary line is updated, the updated boundary line moves to the side of the mode 804, so that the updated area 804 becomes smaller, and part or all of the resources adjacent to the boundary line in the mode 804 are occupied by the UE in the mode 3; the area 805 after updating becomes large.

When the UE in the mode 4 monitors that part or all of the resources adjacent to the boundary line in the mode 805 are occupied by the UE in the mode3, the position of the boundary line is updated, the updated boundary line moves to the side of the mode 805, so that the updated area 805 is reduced, and no resources in the mode 805 are occupied by the UE in the mode 3; the updated 804 area becomes larger, including all resources occupied by mode3 UEs.
