Description

Method for selecting and configuring sidelink transmission resources and equipment

Technical Field

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method for selecting and configuring sidelink transmission resources and equipment.

Background

A Long Term Evolution (LTE) system supports sidelink (or translated to sidelink, etc.) from the 12 th release version, and is used for performing direct data transmission between terminal User equipments (UEs, simply referred to as terminals) without using network side Equipment.

The UE transmits secondary link Control Information (SCI) through a Physical secondary link Control Channel (PSCCH), and schedules transmission of a Physical secondary link Shared Channel (PSCCH) to transmit data. The transmission is performed in a broadcast manner, and the receiving end does not feed back whether the reception is successful to the transmitting end.

The LTE sidelink design supports two resource allocation modes, namely a Scheduled resource allocation (Scheduled resource allocation) mode and an autonomous resource selection (autonomous resource selection) mode. The former is controlled by network side equipment and allocates resources for each UE, and the latter is selected by the UE autonomously.

From release 15, LTE supports sidelink Carrier Aggregation (CA). Unlike the CA and Uu interfaces (i.e., downlink and uplink) of LTE sidelink, there is no division between Primary Component Carrier (PCC) and Secondary Component Carrier (SCC). The UE in autonomous resource selection mode performs resource sensing (sensing) and resource reservation independently on each Component Carrier (CC).

The design of the LTE sidelink is suitable for specific public safety affairs (emergency communication in disaster places such as fire places or earthquakes), vehicle to internet (V2X) communication and the like. The internet of vehicles communication includes various services, such as basic security type communication, advanced (automated) driving, formation, sensor expansion, and the like. Since LTE sidelink supports only broadcast communication, and is therefore mainly used for basic security class communication, other advanced V2X services will be supported by NR sidelink.

The 5G NR system can be used for an operating frequency band above 6GHz which is not supported by LTE, and supports a larger operating bandwidth, but the current version of the NR system only supports an interface between a base station and a terminal, and does not support a Silelink interface for direct communication between terminals.

In the V2X design of NR, how to select the transmission resources of the sidelink to transmit data has not been explicitly described.

Embodiments of the present invention are described below with reference to the accompanying drawings. The method for selecting and configuring the sidelink transmission resource and the equipment provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may adopt a 5G system, or an Evolved Long Term Evolution (lte) system, or a subsequent Evolved communication system.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for selecting sidelink transmission resources according to an embodiment of the present invention, where the method for selecting sidelink transmission resources is applied to a terminal, and includes:

step 21: according to the relevant configuration information of the secondary link, selecting, reselecting or reconfiguring the transmission resources of the secondary link, wherein the transmission resources are as follows: a carrier, a partial Bandwidth (BWP), or a resource pool;

configuration information of quality of service (QoS) requirements corresponding to each of the transmission resources;

configuration information that triggers a Channel Busy Ratio (CBR) threshold for reselecting or reconfiguring the transmission resource;

CBR is a parameter used in V2X for congestion control. The UE measures the CBR value every time it transmits, and for different transmission resources, the UE can dynamically adjust its own transmission parameters, such as maximum transmission power, retransmission times, Modulation and Coding Scheme (MCS), etc., according to the CBR measurement result.

In the embodiment of the invention, when the transmission resource of the secondary link is selected, the QoS requirement and/or CBR information corresponding to the transmission resource are/is considered, so that the communication efficiency is improved.

The reselection of the transmission resource refers to reselecting another transmission resource for transmission when one transmission resource is selected and adopted for transmission at present.

The reallocation of the transmission resource means that, when a transmission resource has been selected and used for transmission at present, a request is sent to the network side device to request the network side device to reallocate the transmission resource for the terminal.

The meaning of the pool of resources (pool) for the sidelink is explained below:

at present, V2X has a concept of "resource pool" when transmitting, where the resource pool is sent or preconfigured by the network side, and the resource pool includes resources used for transmission and many transmission-related parameters, including, for example, an offset value of a first subframe of the resource pool, a bitmap (bitmap) corresponding to the resource pool, whether PSCCH and PSCCH are transmitted in adjacent Resource Blocks (RBs), the number of subchannels and the size of each subchannel, and a lowest RB index value corresponding to the subchannel, a lowest RB index value corresponding to the PSCCH resource pool, a received Signal Strength (S-RSSI) measured by a Channel Busy Ratio (CBR), and a region identifier.

At present, in addition to configuring a normal transmission resource pool for the UE, the network side may also configure an abnormal resource pool (abnormal pool), where the abnormal resource pool is used for some special situations, such as during a handover procedure, or during a Radio Link Failure (RLF) or a transition procedure from an IDLE state (IDLE state) to a CONNECTED state (CONNECTED state), and so on.

In this embodiment of the present invention, the configuration information of the QoS requirement corresponding to the transmission resource includes at least one of:

maximum required communication range (Maximum required communication range);

an index of a maximum transmission distance;

minimum required communication range;

an index of minimum transmission distance;

a transmission distance range;

an index of a transmission distance range;

packet size (Payload);

an index of the packet size;

transmission rate (Transmission rate);

an index of transmission rate;

maximum end-to-end latency (Maximum end-to-end latency);

an index of maximum end-to-end delay;

reliability (Reliability);

an index of reliability;

data rate (Data rate);

an index of the data rate.

In some embodiments of the present invention, the configuration information about the sidelink includes: configuration information of QoS requirement corresponding to each transmission resource; in this case, the selecting, reselecting, or reconfiguring the transmission resource of the secondary link according to the configuration information related to the secondary link includes:

step 211: and according to the QoS requirement of the data packet served by the V2X and the configuration information of the QoS requirement corresponding to each transmission resource, selecting a target transmission resource matched with the QoS requirement of the data packet from the transmission resources of the secondary link.

Or

Step 211': and according to the QoS requirement of the bearer served by the V2X and the configuration information of the QoS requirement corresponding to each transmission resource, selecting a target transmission resource matched with the QoS requirement of the bearer from the transmission resources of the secondary link.

Different V2X services have different QoS requirements, including: in the embodiment of the present invention, when selecting transmission resources, the QoS requirements of different V2X services are considered, so that V2X services with different requirements select different transmission resources, thereby improving communication efficiency.

The sidelink transmission of the LTE system is based on broadcasting, and the terminal does not establish a point-to-point connection in the physical layer, nor does it have a feedback mechanism. The receiving end does not feed back whether the receiving is successful or not to the transmitting end, and can not carry out channel measurement and feed back the measurement result. The V2X research for NR systems is now beginning and there is a trend towards NR systems that support multiple transmission modes, including unicast, multicast and broadcast. Unicast, as the name implies, is a one to one transmission, and multicast is a one to many transmission. Broadcast is also a one to any transmission, but broadcast does not have the concept that UEs belong to the same group. Therefore, in the embodiment of the present invention, the data transmission of the V2X service may be performed in a broadcast manner, which corresponds to the manner of sending the data packet in step 211, or may be performed in a point-to-point manner, that is, a manner of establishing a bearer.

In some embodiments of the present invention, the configuration information of the QoS requirement corresponding to the transmission resource includes: a minimum transmission distance and/or an index of the minimum transmission distance; wherein the minimum transmission distance corresponding to the target transmission resource is less than or equal to the minimum transmission distance of the data packet or bearer serviced by the V2X, or an index of the minimum transmission distance corresponding to the target transmission resource is the same as or has a corresponding relationship with the index of the minimum transmission distance of the data packet or bearer serviced by the V2X; when the index of the minimum transmission distance corresponding to the target transmission resource has a corresponding relationship with the index of the minimum transmission distance of the data packet or the bearer served by the V2X, the minimum transmission distance corresponding to the index of the minimum transmission distance corresponding to the target transmission resource is less than or equal to the minimum transmission distance corresponding to the index of the minimum transmission distance of the data packet or the bearer served by the V2X. For example, the index of the minimum transmission distance of the data packet or bearer serviced by V2X is 01, the corresponding minimum transmission distance is 20 km, and the index having a corresponding relationship with the index 01 includes: the index 10 and the index 11, wherein the minimum transmission distance corresponding to the index 10 is 10 kilometers, and the minimum transmission distance corresponding to the index 11 is 5 kilometers.

In some embodiments of the present invention, the configuration information of the QoS requirement corresponding to the transmission resource includes: maximum transmission distance and/or index of maximum transmission distance; wherein the maximum transmission distance corresponding to the target transmission resource is greater than or equal to the maximum transmission distance of the data packet or bearer served by the V2X, or an index of the maximum transmission distance corresponding to the target transmission resource is the same as or has a corresponding relationship with an index of the maximum transmission distance of the data packet or bearer served by the V2X; when the index of the maximum transmission distance corresponding to the target transmission resource has a corresponding relationship with the index of the maximum transmission distance of the data packet or the bearer served by the V2X, the maximum transmission distance corresponding to the index of the maximum transmission distance corresponding to the target transmission resource is greater than or equal to the maximum transmission distance corresponding to the index of the maximum transmission distance of the data packet or the bearer served by the V2X.

In some embodiments of the present invention, the configuration information of the QoS requirement corresponding to the transmission resource includes: a transmission distance range and/or an index of the transmission distance range, wherein the transmission distance range corresponding to the target transmission resource includes the transmission distance range of the data packet or bearer served by V2X, or the index of the transmission distance range corresponding to the target transmission resource is the same as or has a corresponding relationship with the index of the transmission distance range of the data packet or bearer served by V2X. When the index of the maximum transmission distance range corresponding to the target transmission resource has a corresponding relationship with the index of the transmission distance range of the data packet or bearer serviced by V2X, the transmission distance range corresponding to the index of the transmission distance range corresponding to the target transmission resource includes the transmission distance range corresponding to the index of the transmission distance range of the data packet or bearer serviced by V2X.

In some embodiments of the present invention, the method for selecting sidelink transmission resource may further include:

step 22: if the QoS requirement of the packet serviced by V2X changes, reselecting the transmission resource from the transmission resource of the sidelink, or sending a reconfiguration request to a network side device, where the reconfiguration request is used to request the network side device to reconfigure a new transmission resource for the sidelink.

Or

Step 22': if the QoS requirement of the bearer served by V2X changes, reselecting the transmission resource from the transmission resource of the sidelink, or sending a reconfiguration request to a network side device, where the reconfiguration request is used to request the network side device to reconfigure a new transmission resource for the sidelink.

In the embodiment of the present invention, after the terminal sends the configuration request to the network side device, the network side device may reallocate the transmission resource of the sidelink to the terminal, and then the terminal selects the transmission resource of the sidelink, or alternatively, the network side device may directly indicate the transmission resource of the sidelink used for transmission to the terminal.

In some embodiments of the present invention, the configuration information about the sidelink includes: triggering and reselecting the configuration information of the CBR threshold of the transmission resource;

the selecting, reselecting or reconfiguring the transmission resource of the secondary link according to the relevant configuration information of the secondary link comprises:

step 2121: measuring the CBR of the transmission resource used by the current transmission;

step 2122: and if the CBR or the index of the CBR of the transmission resource used for current transmission meets the configuration information of the CBR threshold, performing reselection or reconfiguration on the transmission resource.

In this embodiment of the present invention, the configuration information of the CBR threshold for triggering reselection of the transmission resource includes at least one of:

a CBR maximum threshold;

an index of the CBR maximum threshold;

a CBR minimum threshold;

an index of the CBR minimum threshold;

a CBR threshold range;

the index of the CBR threshold range.

In the embodiment of the present invention, if the CBR threshold (for example, the CBR maximum threshold, the CBR minimum threshold, or the CBR threshold range) is indicated in the configuration information triggering the reselection of the CBR threshold of the transmission resource, the measured CBR of the transmission resource currently used for transmission is directly compared with the CBR threshold, and whether the CBR of the transmission resource currently used for transmission satisfies the CBR threshold is determined, for example, if the CBR threshold is the CBR maximum threshold, the transmission resource is reselected or reallocated if the CBR of the transmission resource currently used for transmission needs to be greater than the CBR maximum threshold.

In the embodiment of the present invention, if the CBR threshold configuration information for reselecting the transmission resource is triggered to indicate that the CBR threshold index is the CBR threshold index, at this time, the measured CBR index of the transmission resource currently used for transmission is determined, and the CBR index of the transmission resource currently used for transmission is compared with the CBR threshold index, to determine whether the CBR index of the transmission resource currently used for transmission satisfies the CBR threshold index, for example, when the CBR threshold index is the CBR maximum threshold index, if the CBR corresponding to the CBR index of the transmission resource currently used for transmission is greater than the CBE minimum threshold corresponding to the CBR maximum threshold index, the transmission resource is reselected or reallocated.

In this embodiment of the present invention, the CBR of the transmission resource currently used for transmission or the index of the CBR meeting the CBR threshold includes one of:

within a preset time interval M, the number of times that the CBR of the transmission resource used by the current transmission meets the CBR threshold is equal to N, wherein N is a positive integer greater than or equal to 1;

within a preset time interval M, the number of times that the index of the CBR of the transmission resource used by the current transmission meets the index of the CBR threshold is equal to N, wherein N is a positive integer greater than or equal to 1;

the number of times that the CBR of the transmission resource used for the current transmission meets the CBR threshold is equal to N;

the number of times that the index of the CBR of the transmission resource used for the current transmission meets the index of the CBR threshold is equal to N, wherein N is a positive integer greater than or equal to 1.

In this embodiment of the present invention, if the CBR or the index of the CBR of the transmission resource currently used for transmission satisfies the configuration information of the CBR threshold, performing reselection or reconfiguration on the transmission resource includes:

step 21221: if the CBR of the transmission resource currently used for transmission or the index of the CBR meets the configuration information of the CBR threshold, performing reselection of the transmission resource from the transmission resource of the sidelink, or sending a reconfiguration request to a network side device, where the reconfiguration request is used to request the network side device to reconfigure a new transmission resource for the sidelink.

In some embodiments of the present invention, the configuration information about the sidelink includes: configuration information of a QoS requirement corresponding to each transmission resource, and configuration information of a corresponding relation between a CBR of the transmission resource and the QoS requirement;

step 2131: measuring the CBR of the transmission resource used by the current transmission;

step 2132: determining the QoS requirement corresponding to the transmission resource used for the current transmission according to the CBR of the transmission resource used for the current transmission and the configuration information of the corresponding relation between the CBR of the transmission resource and the QoS requirement;

step 2133: and if the determined QoS requirement does not meet the configuration information of the corresponding QoS requirement, performing reselection or reconfiguration on the transmission resources.

That is, if the determined QoS requirement corresponding to the transmission resource currently used for transmission does not satisfy the configuration information of the QoS requirement corresponding to the transmission resource currently used for transmission in the configuration information related to the secondary link, the transmission resource is reselected or reconfigured.

In this embodiment of the present invention, the configuration information of the correspondence between the CBR of the transmission resource and the QoS requirement includes at least one of the following:

and the corresponding relation between the index of the CBR of the transmission resource and the index of the QoS requirement.

When the determined index of the transmission distance range corresponding to the transmission resource used for the current transmission does not have a corresponding relationship with the index of the transmission distance instance corresponding to the transmission resource used for the current transmission in the secondary link related configuration, the determined transmission distance range corresponding to the index of the transmission distance range corresponding to the transmission resource used for the current transmission is not located in the transmission distance range corresponding to the index of the transmission distance range corresponding to the secondary link related configuration.

Of course, part or all of the configuration information related to the secondary link may also be agreed by a protocol.

The following describes a method for selecting the sidelink transmission resource according to an embodiment of the present invention with reference to a specific embodiment.

The first embodiment of the invention:

the transmission resources (carriers, BWPs, or resource pools) of the secondary links configured or preconfigured by the network side device include configuration information of the transmission distance corresponding to each transmission resource when configuring, and the UE selects different transmission resources based on the transmission distance requirements of different services.

Step 1: receiving the relevant configuration information of the sidelink sent by the network side equipment;

Step 2.1: if the packets served by V2X each have a corresponding QoS requirement, the UE selects the transmission resources of the sidelink according to the QoS requirements of the packets served by V2X.

Specifically, if the data packet serviced by V2X has the requirement of maximum transmission distance and/or minimum transmission distance, when selecting the transmission resource of the secondary link, the UE must satisfy the following conditions to select the corresponding transmission resource:

That is, only if the transmission resource satisfies the maximum transmission distance and/or the minimum transmission distance required by the bearer, the transmission resource can be selected or reselected as the transmission resource corresponding to the transmission of the V2X service on the bearer.
