Referring to fig. 1, fig. 1 is a schematic diagram of an architecture of a data transmission system provided in an embodiment of the present application. The data transmission system provided by the present embodiment includes a UE101 and a network device 102.
Alternatively, the UE101 may refer to various forms of user equipment, access terminal, subscriber unit, subscriber station, Mobile Station (MS), remote station, remote terminal, mobile device, terminal device (terminating equipment), wireless communication device, user agent, or user device. The UE may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a Wireless communication function, a computing device or other processing devices connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, which is not limited in this embodiment of the present application as long as the UE101 can wirelessly communicate with the network device 102.
In the embodiment of the application, a unidirectional communication link from an access network to UE is defined as a downlink, data transmitted on the downlink is downlink data, and the transmission direction of the downlink data is called as a downlink direction; the unidirectional communication link from the UE to the access network is an uplink, the data transmitted on the uplink is uplink data, and the transmission direction of the uplink data is referred to as an uplink direction.
Optionally, the Network device 102, that is, a public mobile communication Network device, is an interface device for the UE101 to Access the internet, and is also a form of a Radio Station, and refers to a Radio transceiver Station for performing information transmission with the UE101 in a certain Radio coverage area, and includes a Base Station (BS), which may also be referred to as a Base Station device, and is a device deployed in a Radio Access Network (RAN) to provide a wireless communication function. For example, a device providing a Base Station function in a 2G network includes a Base Transceiver Station (BTS), a device providing a Base Station function in a 3G network includes a node B (NodeB), a device providing a Base Station function in a 4G network includes an Evolved node B (Evolved NodeB, eNB), a device providing a Base Station function in a Wireless Local Area Network (WLAN) is an Access Point (AP), a device providing a Base Station function in a 5G NR is a gNB (Access Point, eNB), and a node B (ng-eNB) continues to evolve, where the gNB and the UE communicate with each other by using an NR technology, the ng-eNB and the UE communicate with each other by using an Evolved universal terrestrial radio Access network (E-eNB) technology, and both the gNB and the ng-eNB may be connected to the 5G core network. The network device 102 in the embodiment of the present application also includes a device that provides a base station function in a future new communication system, and the like.
In a possible implementation manner, the network device may send Uplink scheduling information (UL Grant) to the UE through Downlink Control Information (DCI), which indicates a Physical Uplink Shared Channel (PUSCH) transmission, so that the UE sends data.
Optionally, the UL grant may include the following information:
resource block allocation information (Resource block allocation and hosting Resource allocation);
modulation and coding scheme and redundancy version (Modulation and coding scheme and redundancy) information: a Modulation and Coding Scheme (MCS), a Redundancy Version (RV), and for determining a transport block size (TB size) for specifying a corresponding PUSCH transmission;
new data indicator (New data indicator): for determining whether the current transmission is a new transmission or a retransmission;
scheduling TPC commands for PUSCH: power control for PUSCH;
HARQ process number (HARQ process number): for specifying the HARQ process corresponding to the current transmission.
In addition, for uplink transmission, there are generally two types of pre-configured/semi-static resource (configurable) configuration modes:
pre-configuration (pre-authorization) mode one: configuration (IE Configured Grant configuration) is performed by Radio Resource Control (RRC) layer signaling.
A second pre-configuration (pre-authorization) mode: indicating (activation and deactivation of) the uplink preconfigured/semi-static resources by the DCI, a part of configuration parameters required by the DCI are Configured by the IE Configured Grant configuration, but the uplink preconfigured/semi-static resources can be used only when the DCI is activated.
Optionally, the HARQ uses a stop-and-wait protocol (stop-and-wait protocol) to transmit data, and in the stop-and-wait protocol, after a transmission end transmits a Transport Block (TB), the transmission end stops to wait for acknowledgement information. The receiving end acknowledges the TB with 1 bit of information, either positively (ACK) or Negatively (NACK). But the sender stops waiting for an acknowledgement after each transmission, resulting in low throughput. Thus, multiple stop-and-wait processes in parallel can be used: while one HARQ process is waiting for acknowledgement information, the transmitting end may continue to transmit data using another HARQ process. These HARQ processes together constitute a HARQ entity (HARQ entity) that incorporates a stop-and-wait protocol while allowing continuous transmission of data. Wherein there is one HARQ entity per UE. However, in carrier aggregation, one UE has its HARQ entity for each carrier unit (component carrier).
Optionally, the embodiment of the present application may be applied to various periodic services, and the network device may configure the periodic transmission resource for the UE in a Semi-Persistent Scheduling (SPS) or a Configured/pre-authorized (CG) manner.
Optionally, the embodiments of the present application may also be applied to aperiodic services.
Referring to fig. 2, fig. 2 is a first flowchart illustrating a data transmission method according to an embodiment of the present application, where an execution subject of the embodiment is a UE in the embodiment shown in fig. 1. As shown in fig. 2, the method includes:
s201, in a process that an HARQ process corresponding to a first transmission resource of UE is used for transmitting first data on a second transmission resource of the UE, if it is monitored that second data needing to be transmitted on the first transmission resource is generated in the UE, the UE determines whether the second data is preferentially transmitted on the HARQ process.
In this embodiment of the present application, the first transmission resource and the second transmission resource may be understood as resource blocks located at different time domain positions on the same set of transmission resources of the UE, or may also be understood as resource blocks on two sets of different transmission resources corresponding to the UE.
For example, assuming that the first transmission resource is a resource block on a set of periodic resources Configured by the Configured grant, the second transmission resource may be another resource block on the same set of periodic transmission resources Configured by the Configured grant as the first transmission resource, another resource block on another set of periodic transmission resources Configured by the Configured grant, or a resource block dynamically scheduled by the dynamic grant.
The HARQ process corresponding to the first transmission resource may be occupied by the second transmission resource, and is used for transmitting the first data on the second transmission resource. In a possible embodiment, if the HARQ process corresponding to the first transmission resource of the UE is used to transmit the first data on the second transmission resource, it is monitored whether the second data required to be transmitted on the first transmission resource is generated (or newly arrived) in the UE, and if the second data required to be transmitted on the first transmission resource is generated in the UE, the UE determines whether the second data is preferentially transmitted on the HARQ process.
Second data to be transmitted on the first transmission resource, that is, data to be transmitted corresponding to a Logical Channel with Logical Channel parameter configuration (e.g., allowedSCS-List, maxPUSCH-Duration, configurable Grant Type1 Allowed, Allowed Serving Cells, etc.) matching with corresponding parameter configuration (e.g., SCS, PUSCH-Duration, whether it is configurable Grant Type1, Serving Cell ID, etc.) of the first transmission resource is generated (or newly arrived) in the UE.
Optionally, it may be determined whether the second data is preferentially transmitted in the HARQ process by determining whether the transmission priority of the first transmission resource is higher than the transmission priority of the second transmission resource, or it may be determined whether the second data is preferentially transmitted in the HARQ process by determining whether the transmission priority of the second data is higher than the transmission priority of the first data.
For example, if the transmission priority of the first transmission resource is higher than the transmission priority of the second transmission resource, it is determined that the second data is preferentially transmitted on the HARQ process; or, if the transmission priority of the second data is higher than that of the first data, determining that the second data is preferentially transmitted on the HARQ process.
S202, when it is determined that the second data is preferentially transmitted on the HARQ process, the UE transmits the second data on the first transmission resource by using the HARQ process.
In the embodiment of the present application, when it is determined that the second data is preferentially transmitted in the HARQ process, the UE preferentially transmits the second data on the first transmission resource by using the HARQ process. That is, when it is determined that the second data is preferentially transmitted on the HARQ process, the HARQ process will not transmit the first data but preferentially transmit the second data.
Optionally, when it is determined that the second data is preferentially transmitted in the HARQ process, the UE may clear the buffered data corresponding to the HARQ process, that is, cancel transmission of the first data. After the buffer corresponding to the HARQ process is cleared, a Timer (configured Grant Timer) is restarted for the HARQ process, and the HARQ process is utilized to transmit the second data on the first transmission resource.
Or, when it is determined that the second data is preferentially transmitted on the HARQ process, the UE may clear the buffered data corresponding to the HARQ process, that is, cancel transmission of the first data. After the buffer corresponding to the HARQ process is cleared, a Timer (configured Grant Timer) is restarted for the HARQ process, and meanwhile, the HARQ process is utilized to transmit the second data on the first transmission resource.
In the data transmission method provided in the embodiment of the present application, when the HARQ process on the first transmission resource of the UE is used to transmit the first data on the second transmission resource of the UE, if the second data with higher priority that needs to be transmitted on the first transmission resource is generated in the UE, the second data may be preferentially transmitted on the first transmission resource by using the HARQ process, so that it is ensured that the second data can be transmitted in time.
Based on the content described in the foregoing embodiment, in a possible embodiment of the present application, the manner for determining whether the second data is preferentially transmitted on the HARQ process in step S201 includes:
acquiring the priority of the first transmission resource from the configuration information of the first transmission resource, and acquiring the priority of the second transmission resource from the configuration information of the second transmission resource; when the priority of the first transmission resource is higher than the priority of the second transmission resource, the UE determines that the second data is preferentially transmitted on the HARQ process.
In this embodiment, the network device may add a special indication in the DCI for scheduling the first transmission resource and the second transmission resource, where the special indication may be used to indicate the priority of the first transmission resource and the second transmission resource. The higher the priority of the transmission resource is, the higher the priority of the data transmitted by the transmission resource is. That is, in this embodiment, when the priority of the first transmission resource is higher than the priority of the second transmission resource, it may be determined that the priority of the second data is higher than the priority of the first data, and the second data needs to be transmitted on the HARQ process preferentially.
Optionally, the priority includes any one of the following levels of a target service transmitted by a transmission resource:
the transmission reliability requirement level, the transmission delay requirement level, the transmission priority level, the service transmission quality requirement level and the comprehensive level determined based on the above levels.
Based on the content described in the foregoing embodiment, in another possible embodiment of the present application, the manner for determining whether the second data is preferentially transmitted on the HARQ process in step S201 includes:
acquiring a high priority indication of the first transmission resource from the configuration information of the first transmission resource, and acquiring a high priority indication of the second transmission resource from the configuration information of the second transmission resource; and when the configuration information of the first transmission resource comprises the high priority indication of the first transmission resource and the configuration information of the second transmission resource does not comprise the high priority indication of the second transmission resource, the UE determines that the second data is transmitted on the HARQ process preferentially.
In this embodiment, the network device may add a special indication in the DCI for scheduling the first transmission resource and the second transmission resource. Wherein, the special indication has only two states of 'existence' and 'nonexistence' in the DCI, when the special indication exists in the DCI, the transmission resource which indicates the DCI scheduling is used for transmitting the high priority data; when the special indication is not present in the DCI, the transmission resources indicating the DCI schedule are not used for transmitting high priority data.
That is, in this embodiment, it may be determined whether the second data is preferentially transmitted on the HARQ process based on whether there is a special indication (high priority indication) in the configuration information of the first transmission resource and the second transmission resource.
Based on the content described in the foregoing embodiment, in another possible embodiment of the present application, the manner for determining whether the second data is preferentially transmitted on the HARQ process in step S201 includes:
and when the priority of the highest priority logical channel corresponding to the second data is higher than that of the highest priority logical channel corresponding to the first data, the UE determines that the second data is transmitted on the HARQ process in priority.
Based on uplink transmission resources allocated by the UL grant, the UE needs to determine a total amount of Data of each logical channel included in a new MAC Protocol Data Unit (PDU), and the UE determines which Data of the logical channel is to be placed and how much Data is to be placed in each logical channel based on a configuration given by an RRC signaling logical channel configuration, a Data amount to be transmitted of each logical channel in a UE buffer, a resource configuration indicated in the UL grant, and a rule specified by a Protocol. The priority of each Logical Channel is determined by the priority field of the Logical Channel Config, and the smaller the priority value, the higher the priority of the Logical Channel.
That is, in this embodiment, whether the second data is preferentially transmitted on the HARQ process may be determined based on the priority of the highest priority logical channel corresponding to the second data, and the priority of the highest priority logical channel corresponding to the first data.
Based on the content described in the foregoing embodiment, in another possible embodiment of the present application, the manner for determining whether the second data is preferentially transmitted on the HARQ process in step S201 includes:
acquiring an index value corresponding to a first transmission resource;
when the index value corresponding to the first transmission resource belongs to the preset target index value set, the UE determines that the second data is transmitted on the HARQ process in priority; the target index value set includes at least one target index value.
In this embodiment, the UE first obtains a target Index value (Index) set, where the target Index set includes at least one target Index, such as [ Index 1, Index 3, Index5], and configurable indexes indicated by the target indexes may be used to transmit high-priority data.
The target Index set may be configured by the network device according to data transmission requirements, and the UE acquires the target Index set from the network device. Alternatively, the target Index set may be preconfigured by the communication protocol, and the UE determines the target Index set based on the communication protocol.
Optionally, the transmission resource corresponding to the target Index may be configured in advance for transmitting the high-priority data, or the target Index may not be configured.
For example, assuming that the target Index set acquired by the UE is [ Index 1, Index 3, Index5], when the Index value corresponding to the first transmission resource is any one of Index 1, Index 3, and Index5, it may be considered that the second data is preferentially transmitted on the HARQ process.
In another possible embodiment of the present application, the determining whether the second data is preferentially transmitted on the HARQ process in step S201 further includes:
acquiring an index value corresponding to a first transmission resource;
when the index value corresponding to the first transmission resource is larger than a pre-configured target index value threshold, the UE determines that the second data is transmitted preferentially on the HARQ process;
or when the index value corresponding to the first transmission resource is greater than or equal to the pre-configured target index value threshold, the UE determines that the second data is preferentially transmitted on the HARQ process;
or when the index value corresponding to the first transmission resource is smaller than a pre-configured target index value threshold, the UE determines that the second data is preferentially transmitted on the HARQ process;
or, when the index value corresponding to the first transmission resource is less than or equal to the pre-configured target index value threshold, the UE determines that the second data is preferentially transmitted on the HARQ process.
It can be understood that, when the total configured transmission resources are N sets, if the Index starts to take a value from 0, the value of the Index ranges from 0 to N-1.
For example, assuming that the index value threshold is 3, the total configured transmission resources are N sets, and when the index value corresponding to the first transmission resource is greater than or equal to the preconfigured index value threshold, the UE determines that the second data is preferentially transmitted on the HARQ process, and when the index value corresponding to the first transmission resource is greater than or equal to 3 and is less than any value of N-1, it may be considered that the second data is preferentially transmitted on the HARQ process.
That is, in this embodiment, it may be determined whether the second data is preferentially transmitted on the HARQ process based on the index value corresponding to the first transmission resource.

That is, in the embodiment of the present application, when the HARQ process on the first transmission resource is used to transmit the first data on the second transmission resource, if the UE generates the second data with higher priority that needs to be transmitted on the first transmission resource, the HARQ process may be preferentially used to transmit the second data on the first transmission resource, so that the second data can be transmitted in time.
