Description
Technical Field
The present invention relates to the field of information technologies, and in particular, to a data sending method, a data receiving method, a device, a base station, and a terminal.
Background
With the development of mobile communication technology, mobile communication standards have evolved from 1G (First Generation) to 5G (Fifth Generation). The 5G mobile communication technology has the advantages of large broadband, low time domain and high reliable wireless communication capability, and can meet the wireless access and various data transmission requirements of different terminals in intelligent manufacturing production.
The 5G mobile communication technology is not only applied to public networks, but also applied to industrial enterprise private networks, such as power grids. The main service requirements of the power grid comprise power grid control service, information acquisition service and mobile application service. According to the requirements of these services in terms of bandwidth, time delay, security, and the like, the services can be classified into EMBB (Enhanced Mobile Broadband) Type services, MMTC (massive Machine Type of Communication) Type services, and URLLC (Ultra Reliable Low Latency high reliability) Type services.
In the private network of the industrial enterprise, the EMBB traffic is much larger than the URLLC traffic. When the EMBB has more uplink services and less downlink services, the uplink resources configured in the private network of the industrial enterprise are equal to or greater than the downlink resources in a TDD (Time Division duplex) mode. When a sudden industrial control command is issued, the industrial control command cannot be sent to the terminal from the base station in time due to the lack of downlink resources.

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 only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Embodiments of the present invention provide a data transmission system, method, apparatus, base station, and computer-readable storage medium, which will be described in detail below.
Referring to fig. 1, fig. 1 is a schematic view of a scenario of a data transmission system according to an embodiment of the present invention. The system may include a base station and a target terminal. The base station may be an evolved Node B (eNB) in an LTE system or an evolved system thereof, a macro base station, a small base station, a pico base station, an access point, a transmission point, or a base station in a 5G network. The target terminal includes, but is not limited to, a portable terminal such as a mobile phone and a tablet, a fixed terminal such as a computer and a query machine, and various virtual terminals. The target terminal may communicate with one or more core networks via a Radio Access Network (RAN) or a Radio Access Network NR of 5G.
As shown in fig. 1, a wireless air interface connection is formed between the base station and the target terminal. The industry private network core network server is responsible for transmitting the service data to the base station, and then the base station sends the service data to the target terminal through a wireless air interface. The target terminal receives the control signaling to indicate the target terminal to receive the service data in the non-downlink time slot. And finally, the base station sends the service data to the target terminal in a non-downlink time slot.
In the embodiments of the present invention, description will be made from the viewpoint of a data transmission apparatus, which may be specifically integrated in a base station.
Referring to fig. 2, fig. 2 is a flowchart of a data transmission method according to an embodiment of the present invention, where the method may include:
step S101, sending a receiving control signaling to a target terminal in a cell, wherein the receiving control signaling is used for indicating the target terminal to receive service data in a non-downlink time slot;
step S102, in the non-downlink time slot, the service data is sent to the target terminal.
The following describes the data transmission method in detail, including the following steps:
the service data may be EMBB service data, MMTC service data, or URLLC service data. The URLLC service data is service data with low delay and high reliability. For example, the control command of the photovoltaic power station has a requirement on time delay of 3 milliseconds, and has a requirement on reliability of 99.999% or even higher accuracy, so that the control command of the photovoltaic power station can be regarded as URLLC service data.
In one embodiment, the non-downlink time slots include uplink time slots and/or flexible time slots. The flexible timeslot includes a plurality of OFDM (Orthogonal Frequency Division Multiplexing) symbols, where a transmission direction of each OFDM symbol is variable, for example, one symbol may be used as uplink transmission, downlink transmission, or a guard interval GP for converting uplink transmission and downlink transmission.
As shown in fig. 3, the timeslot is configured with 2 downlink timeslots, 1 special timeslot, and 2 uplink timeslots. As shown in fig. 4, the slot configuration is 2 downlink slots, 1 special slot, and 2 flexible slots.
In an embodiment, after acquiring the service data, the data sending apparatus determines whether the service data needs to be sent to a target terminal in a cell in a subsequent non-downlink time slot, and if the service data does not need to be sent in the non-downlink time slot, the data sending apparatus sends the service data through the downlink time slot. And if the transmission needs to be carried out in the non-downlink time slot, triggering and generating the receiving control signaling and the stopping control signaling.
The receiving control signaling is used for indicating the target terminal to receive the service data in the non-downlink time slot, so that the efficiency of sending the service data can be improved. The stop control signaling is used for instructing all terminals in the cell to stop sending uplink signals in the non-downlink time slot, so that interference on the target terminal for receiving the service data can be prevented. It should be noted that the uplink signal not only includes service data, but also includes a physical signal that does not carry data content, such as a physical signal used for probing and accessing.
It should be noted that, in order to make all terminals know the non-downlink time slot in which the transmission of the uplink signal needs to be stopped, the stop control signaling carries the position information of the non-downlink time slot. For example, when the timeslot configuration is sequentially 2 downlink timeslots, 1 special timeslot, and 2 uplink timeslots, where a non-downlink timeslot is 2 uplink timeslots, if the stop control signaling is sent in the special timeslot, the stop control signaling may carry location information of a "timeslot location 0" field or a "timeslot location 1" field to indicate an uplink timeslot that needs to stop uplink transmission. Wherein, the "slot position 0" field refers to the first uplink slot after the transmission and reception of the stop control signaling, and the "slot position 1" field refers to the second uplink slot after the transmission and reception of the stop control signaling.
Similarly, in order to make the target terminal know the non-downlink timeslot where the service data needs to be received, the received control signaling also carries the location information of the non-downlink timeslot. If the timeslot configuration is set by using a preset timeslot format, the preset timeslot format has N uplink timeslots, and when the receive control signaling is sent in a special timeslot, the receive control signaling may carry "xth (X +1), … …, N uplink timeslot" fields after the special timeslot "to indicate the uplink timeslot where the target needs to receive the service data at the terminal. Wherein X is a positive integer, and the value of X is less than or equal to N.
The data sending device sends the stop control signaling to all terminals in the cell, so that all terminals stop sending uplink signals in the non-downlink time slot according to the stop control signaling. The data sending device sends the receiving control signaling to a target terminal in the cell, so that the target terminal receives the service data in the non-downlink time slot according to the receiving control signaling.
The data transmission method of the embodiment of the invention improves the transmission efficiency of the service data by occupying the non-downlink time slot to transmit the service data.
Referring to fig. 5, fig. 5 is another flowchart of a data transmission method according to an embodiment of the present invention. In the embodiments of the present invention, a description will be made from the perspective of a data transmission apparatus, which may be specifically integrated in a base station. The method can comprise the following steps:
step S201, after the target terminal in the small and medium cell accesses the network, sending first resource configuration information to the target terminal, where the first resource configuration information is used to indicate resource configuration for the target terminal to receive service data in the uplink timeslot.
Step S202, after the service data is obtained, sending the first receiving control signaling to the target terminal in a downlink time slot or a special time slot before the uplink time slot, where the first receiving control signaling is used to instruct the target terminal to receive the service data in the uplink time slot.
Step S203, in the downlink time slot, the service data is sent to the target terminal.
The following describes the data transmission method in steps S201 to S203 in detail:
when a terminal in a cell accesses a network and is in an RRC-Connected state, first resource configuration information is sent to the terminal so as to configure resources of the terminal. The first resource configuration information includes physical layer transmission information.
In an embodiment, the first resource configuration information includes a slot type of receiving the service data and an identification of a terminal receiving the service data.
Taking the service data as URLLC service data as an example, when the type of the timeslot in which the URLLC service data is received in the downlink timeslot is the downlink timeslot, the terminal receives the URLLC service data in the downlink timeslot. And when the types of the time slots for receiving the URLLC service data in the uplink time slot are the downlink time slot and the uplink time slot, the terminal receives the URLLC service data in both the uplink time slot and the downlink time slot.
The terminal receiving the URLLC service data in the uplink timeslot may be a single terminal or a plurality of terminals. Thus, a single terminal and multiple terminals may be distinguished by different identifiers. Specifically, when the identifier of the terminal receiving the URLLC service data is GU-RNTI, it indicates that a group of terminals receive the URLLC service data in the uplink time slot. And when the identification of the terminal receiving the URLLC service data is C-RNTI, the single terminal is indicated to receive the URLLC service data in an uplink time slot.
In an embodiment, the first resource configuration information may further include: the downlink idle physical layer signaling search space used for receiving the service data, the number of subframes, time slots or symbols which are continuously scheduled, whether the terminal returns ACK (forward feedback) after receiving, whether the terminal returns NACK (Negative feedback) after receiving, the DMRS (demodulation reference signal) format corresponding to the service data, and whether the uplink time slot preemption indication UPCI-RNTI is received.
In an embodiment, after acquiring the service data, the data sending apparatus determines whether the service data needs to be sent to a target terminal in a cell in a subsequent uplink timeslot, and if so, triggers generation of a first reception control signaling.
The first receiving control signaling carries a field allowing the target terminal to receive in an uplink time slot, and is used for indicating the target terminal to receive service data in the uplink time slot.
In an embodiment, the first receiving control signaling carries position information of an uplink timeslot. The data transmitting device transmits a first receiving control signaling to the target terminal in a downlink time slot or a special time slot before the uplink time slot. When transmitting in a special slot, it is transmitted in the downlink symbol of the special slot. After receiving the first receiving control signaling, the target terminal can know the uplink time slot required to receive the service data according to the position information of the uplink time slot carried by the target terminal.
In an embodiment, the first reception control signaling may further carry an identifier of a terminal that can receive the service data in the uplink timeslot, that is, an identifier of the target terminal. Further, the first receiving control signaling can also carry UPCI-RNTI scrambling. Wherein, the UPCI-RNTI is used for distinguishing the terminals.
At this time, the data transmission apparatus transmits the first reception control signaling to all terminals in the cell, causes all terminals to stop uplink transmission in the uplink time slot, and causes the target terminal to receive the traffic data in the uplink time slot. The first received control signaling may adopt a preset field format to carry the location information of the uplink timeslot and the identifier of the target terminal. The format of the preset field is as follows: uplink time slot position and identification of a target terminal.
Specifically, assume that there are two uplink timeslots — uplink timeslot 0 and uplink timeslot 1, 4 target terminals — target terminal 1, target terminal 2, target terminal 3, and target terminal 4. When the first receiving control signaling carries 'uplink time slot 0, UE id 1 and UE id 2'; uplink timeslot 1, ue id 3 ", the target terminal 1 and the target terminal 2 will receive the service data in uplink timeslot 0. The target terminal 1 and the target terminal 3 will receive the traffic data in the uplink time slot 1.
And finally, the data transmitting device transmits the service data to the target terminal in the uplink time slot. Or, the data transmitting device transmits the service data to the target terminal in the uplink time slot within the preset time period.
The data transmission method of the embodiment of the invention improves the transmission efficiency of the service data by occupying the uplink time slot to transmit the service data.
Referring to fig. 6, fig. 6 is a flowchart illustrating a data transmission method according to an embodiment of the present invention. In the embodiments of the present invention, description will be made from the viewpoint of a data transmission apparatus, which may be specifically integrated in a base station. The method can comprise the following steps:
step S301, after the target terminal in the cell accesses a network, sending second resource configuration information to the target terminal, where the second resource configuration information is used to indicate resource configuration of the target terminal for receiving service data in the flexible time slot.
Step S302, after acquiring the service data, determining whether the downlink timeslot or the special timeslot exists before the flexible timeslot to send the second receive control signaling, where the second receive control signaling is used to instruct the target terminal to receive the service data in the flexible timeslot.
Step S303, if the downlink time slot or the special time slot exists for sending the second receiving control signaling, sending the second receiving control signaling through the downlink time slot or the special time slot;
step S304, if the downlink timeslot does not exist or the special timeslot transmits the second reception control signaling, transmitting the second reception control signaling through the first symbol of the flexible timeslot.
Step S305, in the flexible time slot, the service data is sent to the target terminal.
The following describes the data transmission method in steps S301 to S305 in detail:
and when the terminal in the cell accesses the network and is in an RRC-Connected state, sending second resource configuration information to the terminal, wherein the second resource configuration information is used for indicating the resource configuration of the target terminal for receiving the service data in the flexible time slot. Wherein the second resource configuration information comprises physical layer transmission information.
In an embodiment, the second resource configuration information includes an identifier of receiving the service data using the flexible timeslot, and a length of a guard interval GP in the flexible timeslot. When the length of the GP is equal to or less than 0, it means that there is no GP. Further, the second resource configuration information further includes: downlink air interface DMRS signal formats used by service data, wherein each DMRS format corresponds to the number of continuously scheduled subframes, time slots or symbols, whether the terminal feeds back ACK after receiving the service data or not, and whether the terminal feeds back NACK after receiving the service data or not; whether the base station retransmits after receiving the NACK, whether a low-priority HARQ (Hybrid Automatic Repeat reQuest) process can be preempted or can be preempted; information such as the number of the emptied HARQ process.
In an embodiment, after acquiring the low-latency high-reliability service data, the data sending apparatus determines whether the service data needs to be sent to the target terminal in the cell in the subsequent flexible time slot. And if not, transmitting the service data to the target terminal in the downlink time slot. Triggering generation of the second received control signaling, if needed. The second receiving control signaling is used for indicating the target terminal to receive the service data in the flexible time slot.
The data transmitting device may transmit the second receive control signaling to the target terminal in the downlink timeslot or the special timeslot before the flexible timeslot, or may transmit the second receive control signaling in the first symbol of the flexible timeslot.
In one embodiment, it is first determined whether there is a downlink timeslot or a special timeslot before the flexible timeslot for sending the second receive control signaling. If the downlink time slot or the special time slot exists for sending the second receiving control signaling, the second receiving control signaling is sent through the downlink symbol in the downlink time slot or the special time slot; and if the downlink time slot or the special time slot does not exist for sending the second receiving control signaling, sending the second receiving control signaling through the first symbol of the flexible time slot.
When the second receiving control signaling is sent through the downlink time slot or the special time slot, the second receiving control signaling carries the position information of the flexible time slot and the identification of the terminal for receiving the service data. The location information of the flexible time slot includes sequence numbers of the flexible time slot, for example, three flexible time slots, and the flexible time slot may be identified by sequence numbers 0,1, and 2.
It should be noted that the first symbol of the flexible timeslot is a downlink symbol. When the second reception control signaling is sent through the first symbol of the flexible slot, the second reception control signaling carries information of other symbols in the flexible slot, such as the role of the symbol, the direction of the symbol, and the like.
The symbol direction of the flexible time slot can be configured by adopting various time slot configuration modes. The flexible slot is assumed to have 14 symbols. The other 13 symbols may be set as follows: the second symbol may be a null or downlink symbol, and when the second symbol is null, the reserved downlink is transferred to the uplink GP. And when the second symbol is a downlink symbol, the second symbol is used for transmitting service data. The third symbol may be null or a downlink symbol, and when the cell coverage is large, the third symbol may be set to null. When used for transmitting traffic data, the third symbol is set as a downlink symbol. The remaining fourth to fourteenth symbols may be set as downlink symbols or uplink symbols.
Specifically, as shown in fig. 7, 13 symbols are downlink symbols except that the first symbol is a downlink symbol. Or the second and the third symbols are null, and the other 11 symbols are uplink symbols.
In practical applications, in an embodiment, the value of the second symbol and the value of the third symbol may be set to 1 to represent GP. The remaining fourth to fourteenth symbols are denoted as uplink symbols when the value is 1, and denoted as downlink symbols when the value is 0. In an embodiment, whether a GP exists may be determined in the second to fourteenth symbols, if a GP exists, the symbols subsequent to the GP are all uplink symbols, and if no GP exists, all the symbols after the second symbol are downlink symbols.
In the flexible timeslot, a GP needs to be set in the uplink and downlink conversion process, where the number of the GPs may not be limited, but too many symbols may be wasted. It is possible to set only one GP per symbol transition of a slot. The uplink and downlink combinations of 13 symbols are 22, that is, 22 time slot configuration formats can be obtained, and specifically, the time slot configuration formats can be stored in a table manner, as shown in table 1 below. Wherein O represents null. U represents an uplink. And D represents a downlink. It should be noted that the bitmap representation requires 26 bits, and the 22 combinations of the sequence numbers require only 5 bits.
TABLE 1
And when the terminal receives the second receiving control signaling in the downlink time slot or the special time slot before the flexible time slot, the terminal prepares to receive the service data in the flexible time slot. And when the terminal receives the second receiving control signaling in the first symbol of the flexible time slot, the terminal prepares to receive the service data in the subsequent symbols of the flexible time slot. When the terminal does not receive the second reception control signaling, it neither transmits nor receives in the flexible time slot.
The data transmission method of the embodiment of the invention improves the transmission efficiency by occupying the flexible time slot to transmit the service data.
The present embodiment will be further described from the perspective of a data receiving device that can be integrated in a terminal according to the method described in the above embodiment.
