It should be noted that the specific type of the network-side device 12 is not limited in the embodiment of the present invention.
Referring to fig. 2, fig. 2 is a flowchart of a resource selection method according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
in this embodiment, each user terminal participating in the collaborative information interaction service is provided with a trigger condition, and the trigger condition is used for triggering the user terminal to send the collaborative information interaction service. Specifically, the trigger condition may be configured by the network side device, or may be agreed by a protocol. The specific content of the trigger condition may be set according to actual needs, and is not further limited herein.
In this embodiment, the baseband parameters may include a first baseband parameter for controlling the signaling SA and a second baseband parameter for the data.
It should be noted that the first baseband parameter and the second baseband parameter may be the same or different. The preset rule may be set according to actual needs, and in this embodiment, the preset rule includes multiple rules, specifically, the preset rule includes any one of the following rules:
rule one is as follows: and selecting a first baseband parameter according to the corresponding relation between the condition parameter and the target object, wherein the second baseband parameter is the same as the first baseband parameter.
Rule two: and selecting a second baseband parameter according to the corresponding relation between the condition parameter and the target object, wherein the first baseband parameter is a fixed parameter value configured by network side equipment or agreed by a protocol.
Rule three: and respectively selecting a first baseband parameter and a second baseband parameter according to the corresponding relation between the condition parameter and the target object, wherein the first baseband parameter is the same as or different from the second baseband parameter.
Rule four: and when the SA or the data which are sent by other user terminals except the user terminal and indicate the first service are received, taking the received baseband parameter of the SA as the first baseband parameter and taking the received baseband parameter of the data as the second baseband parameter.
Rule five: and taking the baseband parameters of the synchronization signals as the first baseband parameters and the second baseband parameters under the condition of receiving the synchronization signals which are sent by other user terminals except the user terminal and indicate the first service.
The target object is optional baseband parameter configuration configured by a network side device or agreed by a protocol, the baseband parameter configuration includes time domain resource granularity configuration and frequency domain resource subcarrier spacing configuration, and the condition parameter includes at least one of service delay requirement, data transmission rate requirement, reliability requirement, quality of service (QoS) and moving speed of a user terminal.
In this embodiment, the traffic delay requirement may be prioritized for rule one, rule two, and rule three. When the first baseband parameter or the second baseband parameter is selected according to the corresponding relationship between the condition parameter and the target object, the selection mode may be set according to actual needs, and no further limitation is made here. Such as low latency requirements for shorter time domain resource granularity configurations, high data transmission rate requirements for larger subcarrier spacing configurations, high reliability requirements, high quality of service QoS requirements, high mobile speed for user terminals for longer time domain resource granularity configurations,
in this embodiment, a carrier may include one or more fractional bandwidths. After determining the baseband parameters, if the baseband parameters correspond to the carriers or partial bandwidths one by one, the carriers and/or partial bandwidths can be determined directly according to the selected baseband parameters; if the corresponding relationship between the baseband parameters and the carriers or the partial bandwidths is one-to-many, the carriers and/or the partial bandwidths can be selected according to other corresponding parameters. Specifically, the other corresponding parameters may include: the corresponding relation between the candidate partial bandwidth and the service attribute, the load of the candidate partial bandwidth and the result of excluding the resource occupation on the candidate partial bandwidth.
In this embodiment, the target time-frequency resource may be selected according to the selection process of the transmission resource on the LTE-V2X single carrier. The existing selection process of sending resources on a LTE-V2X single carrier comprises the following three steps:
step one, marking all candidate resources in a resource selection window as available;
secondly, removing occupied resources, wherein the occupied resources comprise two types;
specifically, in this step, in the sending window, the UE itself transmits and cannot monitor the service packet transmitted by another UE on the transmission subframe, where the subframe is a skip subframe. It needs to be assumed that other UEs on the subframe reserve the next resource in all periods configured by the system, and the reserved resource overlaps with the candidate subframe, or overlaps with the 1, 2, …, 10 × counter-1 transmission subframe after the candidate subframe, and the candidate subframe needs to be excluded. The candidate subframe occupies resources for the first class defined by LTE-V2X.
And monitoring SAs sent by other UEs in the sending window, and according to the period and resource reservation information obtained from the SAs, if reserved resources are overlapped with candidate resources or overlapped with 1, 2, …, 10 × counter-1 times of sending resources after the candidate subframe, and PSSCH-RSRP measured according to the SAs is higher than a threshold value, the corresponding candidate resources need to be eliminated. The corresponding candidate resource is the second type occupied resource defined by LTE-V2X.
If the residual resource proportion is lower than 20 percent after the second step of elimination, the threshold value is increased by 3dB, and the elimination process is executed again until the residual resource proportion reaches or is higher than 20 percent.
And thirdly, performing S-RSSI measurement and sequencing on the candidate resources, selecting the 20 percent of resources with the lowest S-RSSI measurement value, and selecting the resources from the 20 percent of candidate resources by a high layer.
Based on the existing selection process of sending resources on LTE-V2X single carrier, in this embodiment, the process of selecting the target time-frequency resource includes the following four steps:
determining a first candidate time-frequency resource in a resource selection window on the carrier and/or a part of bandwidth;
removing occupied resources of the first candidate time frequency resources to obtain second candidate time frequency resources;
S-RSSI measurement is carried out on the second candidate time frequency resources, and the first N second candidate time frequency resources with the lowest S-RSSI measurement values are selected;
selecting a target time frequency resource for sending the first service from the N second candidate time frequency resources;
wherein N is a positive integer, and N is determined according to a preset proportion (for example, 20%) of the first candidate time-frequency resource (the first candidate time-frequency resource is all candidate resources in a resource selection window in a selection process of a transmission resource on an existing LTE-V2X single carrier).
Specifically, the occupied resource can be excluded in a manner consistent with or different from the existing occupied resource exclusion manner. In this embodiment, optionally, the occupied resources may include a newly defined first occupied resource and a second occupied resource defined in LTE-V2X, where the second occupied resource includes the first occupied resource and a second type occupied resource. Thus, in this embodiment, the above excluding occupied resources from the first candidate time-frequency resource to obtain a second candidate time-frequency resource includes:
excluding a first occupied resource from the first candidate time-frequency resource, wherein the first occupied resource comprises at least one of a first sub time-frequency resource and a second sub time-frequency resource;
after the first occupied resource is eliminated, eliminating a second occupied resource from the first candidate time frequency resource to obtain a second candidate time frequency resource, wherein the second occupied resource is an unavailable resource specified by LTE-V2X;
the first sub time-frequency resource comprises all resources on a time domain resource where a first sending resource is located, and the first sending resource is occupied and/or reserved resources indicated by SA or data of other indication first services of the same type system which are received by the user terminal; the second sub time-frequency resource comprises all resources on a time domain resource where a second sending resource is located, the second sending resource is a resource occupied and/or reserved by a second service sent by the user terminal, and the second service is other services except the first service.
By excluding the first sub-time frequency resource, the selected target time frequency resource and the resource of the cooperative information interaction service of other user terminals are not overlapped in time domain. And simultaneously, the second sub time frequency resource is eliminated, so that the selected target time frequency resource can avoid the conflict with the resource sent by the second service of the user terminal in the time domain. Therefore, the problem that the final decision is influenced because part of services cannot be successfully received due to half-duplex influence of the services needing the collaborative information interaction can be effectively avoided.
In the embodiment of the invention, before the user terminal starts to send the first service, the baseband parameters are selected according to a preset rule; the first service is a collaborative information interaction service; after selecting the baseband parameters, determining a transmission carrier and/or a partial bandwidth; and selecting a target time-frequency resource for sending the first service on the carrier and/or a part of bandwidth. Therefore, resource selection of sending the cooperative information interaction service can be realized in the NR system, flexible baseband parameter configuration is supported, and the low delay requirement of the cooperative driving service can be met.
Further, in this embodiment, since the first occupied resource is already excluded, in order to improve the processing efficiency when excluding the second resource, the measurement of psch-RSRP is not performed on the first occupied resource.
After the target time-frequency resource is selected, the target time-frequency resource may collide with the transmission resource of the second service of the user terminal in the time domain. Specifically, after the step 203, the method may further include:
and if the target time-frequency resource conflicts with a resource sent by a second service of the user terminal in a time domain, giving up the sending of the second service, wherein the second service is other services except the first service.
Therefore, the first service is normally sent on the target video resource, the sending reliability of the collaborative information interaction service is ensured, and the influence of the sending of the second service on the sending of the first service is avoided.
Further, after the step 203, the method may further include:
and if the occupied and/or reserved transmission resource indicated by the received other control signaling SA or data indicating the driving service of the same type of system is overlapped with the resource transmitted by the second service of the user terminal in the time domain, the transmission of the second service is abandoned, wherein the second service is other services except the first service.
In this embodiment, when the second service transmission of the ue is overlapped with the transmission resources of other ues in the time domain, the transmission of the second service of the ue is abandoned, so that it is avoided that the first service transmitted by other ues cannot be received due to the transmission of the second service, thereby ensuring the reliability of receiving the collaborative information interaction service and avoiding the influence of the transmission of the second service on the reception of the first service.
Optionally, in this embodiment, the SA of the first service may be used to indicate a transmission parameter of the first service; the transmission parameters include at least one of:
SA sends frequency band indication;
SA sends carrier indication;
the SA sends a partial bandwidth BWP indication;
SA sends time frequency resource indication;
data sending frequency band indication;

Further, the sending parameters further include:
in a priority domain in the SA, setting the priority of a first service as the highest priority;
or, in the SA newly-added indication field, the data indicated by the SA is used to indicate that the data is the first service.
Optionally, the multiplexing mode of the SA and the data may be set according to actual needs, for example, in this embodiment, the SA and the data in the first service are in a time division multiplexing TDM and/or a frequency division multiplexing FDM mode.
It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.
