Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the related art, a Long Term Evolution (LTE)/Long Term Evolution-enhanced (LTE-a) communication system supports a sidelink (SL, Side Link), which can be used for direct data transmission between User Equipments (UEs) without passing through a network Side device.
As shown in fig. 1, the network side device is taken as a base station for illustration, the base station may be an evolved Node B (eNB or e-NodeB), and the base station and the UE1 can respectively implement UpLink data transmission and downlink data transmission through an UpLink (UL) and a Downlink (DL), while the UE1 can directly perform data transmission with other UEs, such as the UE2, the UE3, and the UE4 shown in fig. 1, through a SL.
User Equipment (UE), also referred to as Terminal Equipment (Mobile Terminal), Mobile User Equipment, etc., may communicate with one or more core networks via a Radio Access Network (RAN, Radio Access Network, for example), where the UE may be Terminal Equipment, such as a Mobile phone (or referred to as a "cellular" phone) and a computer having the Terminal Equipment, such as a portable, pocket, hand-held, computer-embedded, or vehicle-mounted Mobile device, which exchange languages and/or data with the Radio Access Network.
Currently, a secondary link design in an LTE/LTE-A communication system is suitable for specific public safety services, such as emergency communication affairs in fire places or disaster places such as earthquakes; or various services suitable for internet of vehicles communication, such as: basic security type communication, advanced automatic driving, formation, sensor expansion and the like. In addition, considering that the design of the sidelink in the LTE/LTE-a communication system only supports broadcast communication, it is mainly applied to basic security class communication services. Thus, for other advanced V2X services with strict quality of service (qos) requirements in terms of latency, reliability, etc., it can be supported by the design of SL in the 5G NR communication system, where the 5G NR communication system can be used in an operating frequency band above 6GHz that is not supported by the LTE/LTE-a communication system, and can support a larger operating bandwidth, and the 5G NR communication system at least supports an interface between a network-side device and a terminal device, where the network-side device may be a 5G base station (gNB).
In addition, the UE in the LTE/LTE-a communication system and the 5GNR communication system may report the BSR, taking basic uplink scheduling in the LTE/LTE-a communication system as an example, as shown in fig. 2, when the UE has uplink Data to send, the UE sends an SR on a specified SR resource, the eNB receives the SR of the UE and knows that the UE has uplink Data to send, the eNB schedules the UE to send uplink, that is, the UE may send the BSR and possible partial Data on a resource corresponding to an uplink grant UL grant of the eNB, and then the eNB may know how much uplink Data the UE has to transmit according to the BSR, and then the eNB may schedule Data according to the Data amount of the uplink Data and the priority of the Data service, so it can be seen that the BSR functions to inform the UE of how much uplink Data the eNB has to transmit through the BSR.
Similarly, for the allocation mode of the scheduling resource of the sidelink SL, after the UE reports the SR corresponding to the SL, the UE reports the BSR corresponding to the SL to the base station on the resource corresponding to the uplink grant UL grant, and then the base station determines how many SL resources to allocate to the UE for the transmission of the sidelink data, that is, the BSR corresponding to the SL functions as: through which the UE informs the eNB how much sidelink data is to be transmitted.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 3, a first uplink transmission method provided in the embodiment of the present invention is applied to a terminal device. The method comprises the following steps:
s301: under the condition that uplink resources used for transmitting the target scheduling request SR conflict with other resources, whether the operation of transmitting the target SR on the uplink resources is executed or not is determined according to a scheduling request transmission rule corresponding to the target service quality requirement, wherein the target SR is the SR triggered by the target buffer status report BSR, and the target BSR is the BSR triggered by the sidelink pending-transmission data.
Optionally, in the embodiment of the present invention, the scheduling request transmission rule corresponding to the target qos requirement may be formulated by the network side device and then notified to the terminal device, or may be a rule written into the communication protocol in advance, when the terminal equipment performs uplink transmission, according to the execution, that is, under the condition that the uplink resource which is allocated by the network side equipment and used for transmitting the target scheduling request SR conflicts with other resources, the terminal device may determine whether to preferentially perform an operation of transmitting the target SR on the uplink resource according to the scheduling request transmission rule, namely, the transmission priority of different types of service operation including the target SR uplink transmission operation is determined, especially the execution situation of the scheduling request uplink transmission corresponding to the data to be transmitted by the secondary link is determined, the problem of resource scheduling conflict is effectively solved, and the transmission requirements of different types of services are met.
It can be understood that the conflict between the uplink resource allocated by the network side device to the terminal device for transmitting the target SR and other resources may refer to a situation where the conflict occurs in at least one of different latitudes, such as a time domain, a frequency domain, a space domain, and a code domain.
It can be understood that, when the terminal device needs to transmit data through the Sidelink, a target BSR (may also be referred to as Sidelink BSR, SLBSR for short) is generated based on the Sidelink to-be-transmitted data trigger to inform the network side device of how much Sidelink data is to be transmitted, and reporting of a target SR (may also be referred to as Sidelink SR, SLSR for short) is triggered based on the target BSR, so that after the target SR and the target BSR are reported to the network side device in sequence, the network side device determines how much resources are allocated to the terminal device for transmitting the Sidelink data.
The following describes the contents of the scheduling request transmission rule in detail according to the difference between other resources that conflict with the uplink resource used for transmitting the target SR.
Optionally, in this embodiment of the present invention, when the other resources are configuration resources for performing measurement in a measurement GAP, and the target qos requirement is a first qos requirement corresponding to data to be transmitted by a sidelink, the scheduling request transmission rule may include:
and under the condition that the first service quality requirement meets a first preset condition, executing the operation of transmitting the target SR on the uplink resource.
It can be understood that, when the terminal device performs the inter-frequency measurement, a part of time is reserved, and in this period of time, the terminal device does not send and receive any data, but tunes its receiver to the frequency point of the target cell to perform the inter-frequency measurement, and tunes its reception to the local cell where the terminal device is currently located when this period of time is over, where this period of time is the measurement GAP, and then other resources may be configuration resources for the terminal device to perform the measurement in the measurement GAP.
In this embodiment of the present invention, when an uplink resource used for transmitting a target SR conflicts with other resources, it may be determined whether to make a sequence for performing an operation of transmitting the target SR on the uplink resource better than a sequence for performing an operation of performing inter-frequency measurement by a terminal device based on a quality of service requirement corresponding to transmission of data to be transmitted in the secondary link, where optionally, the scheduling request transmission rule includes: and when a first service quality requirement corresponding to the data to be transmitted on the secondary link meets a first preset condition, the terminal equipment can preferentially execute the operation of transmitting the target SR on the uplink resource.
It can be understood that, when the service quality requirement corresponding to the data to be transmitted on the secondary link meets a certain condition, the operation of transmitting the target SR on the uplink resource is determined to be preferentially executed, that is, when the uplink transmission resource is applied, the service quality of the service data to be transmitted carried on the secondary link is fully considered, so that the quality requirement required by the service of the data to be transmitted on the secondary link is met by improving the transmission priority of the target SR corresponding to the data to be transmitted on the secondary link, and particularly, the service quality requirement of the advanced V2X service with the characteristics of low time delay, high reliability and the like can be met.
Optionally, in this embodiment of the present invention, when the other resources are resources used for transmitting data to be transmitted in an uplink, and the target qos requirement includes at least one of a first qos requirement corresponding to the data to be transmitted in a sidelink and a second qos requirement corresponding to the data to be transmitted in the uplink, the scheduling request transmission rule may include:
and under the condition that at least one of the first service quality requirement meets a first preset condition and the second service quality requirement meets a second preset condition, executing the operation of transmitting the target SR on the uplink resource.
In this embodiment of the present invention, when an uplink resource used for transmitting a target SR conflicts with other resources, it may be determined whether to make an order of performing an operation of transmitting the target SR on the uplink resource better than an order of performing an operation of transmitting uplink data to be transmitted based on at least one of a first quality of service requirement corresponding to transmission of the data to be transmitted in the sidelink and a second quality of service requirement corresponding to transmission of the data to be transmitted in the uplink, and optionally, the scheduling request transmission rule includes: under the condition that at least one of a first service quality requirement corresponding to the data to be transmitted of the secondary link meets a first preset condition and a second service quality requirement corresponding to the data to be transmitted of the uplink meets a second preset condition, the terminal equipment can preferentially execute the operation of transmitting the target SR on the uplink resource.
It can be understood that, when the quality of service requirement corresponding to the data to be transmitted on the secondary link and/or the quality of service requirement corresponding to the data to be transmitted on the uplink satisfy the corresponding conditions, it is determined that the operation of transmitting the target SR on the uplink resource is preferentially performed, that is, when the uplink transmission resource is applied, the quality of service of the service data to be transmitted carried on the secondary link and/or the quality of service of the service data to be transmitted carried on the uplink are/is fully taken into consideration, so that the quality requirement required by the service of the data to be transmitted on the secondary link is satisfied by increasing the transmission priority of the target SR corresponding to the data to be transmitted on the secondary link, and particularly, the quality of service requirement of the high-level V2X service having the characteristics of low time delay, high reliability, and the like can be satisfied.
Optionally, when at least one of the following conditions is satisfied, it is determined that the first quality of service requirement satisfies a first preset condition:
the transmission priority of the data to be transmitted of the secondary link is higher than a first preset priority threshold value;
the transmission delay of the data to be transmitted of the secondary link is lower than a first preset delay threshold value;
the transmission reliability value of the data to be transmitted of the secondary link is higher than a first preset reliability threshold value;
the communication distance of the data to be transmitted of the secondary link is higher than a first preset distance threshold value;
the data size of the data to be transmitted of the secondary link is higher than a first preset data size threshold value;
the sending rate of the data to be transmitted of the secondary link is higher than a first preset sending rate threshold value;
the data rate of the data to be transmitted in the secondary link is higher than a first preset data rate threshold value.
In the embodiment of the invention, for the service quality of the data to be transmitted in the secondary link, the requirements can be preferably made on seven parameters of transmission priority, transmission delay, transmission reliability value, communication distance, data size, sending rate and data rate; of course, other qos parameters may be added or some qos parameters may be reduced according to actual requirements. In this way, when the first quality of service requirement corresponding to the data to be transmitted on the secondary link is at least one of the above requirements, that is, when the quality of service requirement of the data to be transmitted on the secondary link is relatively high, the terminal device can preferentially execute the operation of transmitting the SR corresponding to the data to be transmitted on the secondary link on the corresponding uplink resource.
Optionally, the value taking conditions of the first preset priority threshold, the first preset delay threshold, the first preset reliability threshold, the first preset distance threshold, the first preset data size threshold, the first preset sending rate threshold, and the first preset data rate threshold may set different values according to different service types, and the like.
Optionally, determining that the second quality of service requirement meets a second preset condition when at least one of the following conditions is true:
the transmission priority of the uplink to-be-transmitted data is lower than or equal to a second preset priority threshold value;
the transmission delay of the uplink to-be-transmitted data is higher than or equal to a second preset delay threshold value;
and the transmission reliability value of the uplink to-be-transmitted data is lower than or equal to a second preset reliability threshold value.
In the embodiment of the invention, the service quality of the data to be transmitted in the uplink can be preferably required from the aspects of three parameters of transmission priority, transmission delay and transmission reliability value; of course, other qos parameters may be added or some qos parameters may be reduced according to actual requirements. In this way, when the second qos requirement corresponding to the data to be transmitted in the uplink is at least one of the above requirements, that is, when the qos requirement of the data to be transmitted in the uplink is relatively low, the terminal device can preferentially execute the operation of transmitting the SR corresponding to the data to be transmitted in the sidelink on the corresponding uplink resource.
Optionally, the value conditions of the second preset priority threshold, the second preset delay threshold, and the second preset reliability threshold may set different values according to different service types and the like.
Optionally, the data to be transmitted in the secondary link may be a data packet to be transmitted in the secondary link or a data stream to be transmitted in the secondary link; the data to be transmitted in the uplink may be a data packet to be transmitted in the uplink or a data stream to be transmitted in the uplink.
Optionally, the network side device may be a 5G base station (gNB), but the embodiment of the present invention is not limited thereto.
In the embodiment of the invention, when resource scheduling conflicts, the execution condition of scheduling request uplink transmission corresponding to the data to be transmitted of the secondary link is determined according to the pre-established scheduling request transmission rule corresponding to the target service quality requirement, so that the problem of resource scheduling conflicts is effectively solved, and the transmission requirements of different types of services are met.
It can be understood that, after receiving the uplink authorization information of the terminal device for the target SR, the terminal device may smoothly report the target BSR on the resource corresponding to the uplink authorization information, so that the network side device allocates the corresponding SL resource based on the target BSR to complete transmission of the sidelink to-be-transmitted data.
Referring to fig. 4, a second uplink transmission method provided in the embodiment of the present invention is applied to a terminal device. The method comprises the following steps:

Optionally, the target BSR (which may also be referred to as a Sidelink BSR, or SLBSR for short) includes a conventional type or a Padding type, that is, the target BSR may be a Padding type BSR that is sent by being carried by Padding Bits (Padding Bits), or may be a conventional type BSR that is not sent in the Padding Bits, where the Padding type BSR means that resources allocated by the network-side device are relatively large for the data of the current uplink transmission, and some of the Padding Bits do not need to transmit the data, and these Padding Bits may be used for sending when the target BSR is transmitted in the uplink, so as to achieve the purpose of improving resource utilization.
S403: and under the condition that resources corresponding to the uplink authorization information are not enough to support the transmission of the target BSR and other objects, determining whether to preferentially transmit the target BSR on the resources corresponding to the uplink authorization information according to a buffer status report transmission rule corresponding to the target service quality requirement.
Optionally, in this embodiment of the present invention, a buffer status report transmission rule corresponding to the target qos requirement may be formulated by a network side device and then notified to a terminal device, or may be a rule written in a communication protocol in advance, so that when the terminal device performs uplink transmission, according to execution, that is, when an allocated resource carried in uplink authorization information by the network side device is not sufficient to support transmission of the target buffer status report BSR and another object to be transmitted, that is, when an uplink resource is insufficient, the terminal device may determine, according to the buffer status report transmission rule, whether an object preferentially sent on a resource corresponding to the uplink authorization information is the target BSR, that is, determine a transmission priority of different types of services including the target BSR on a resource corresponding to the uplink authorization information, and particularly determine an execution condition of uplink transmission of a buffer status report corresponding to sidelink pending data, the problem of resource scheduling conflict is effectively solved, and the transmission requirements of different types of services are met.
It can be understood that, when the terminal device needs to transmit data through the sidelink, a target BSR is generated based on the sidelink to-be-transmitted data trigger to inform the network side device of how much sidelink data the network side device has to transmit, and after the target BSR is reported to the network side device, the network side device determines how much resources are allocated to the terminal device for transmitting the sidelink data.
The following describes the content of the transmission rule of the buffer status report in detail according to the difference between other objects that have transmission conflicts with the target BSR on the resources corresponding to the uplink grant information.
