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.
The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the 5G network, after the base station configures the eMMC service terminal scheduling authorization, the base station suddenly receives a scheduling request of the URLLC service terminal, and in order to ensure URLLC service experience, the time-frequency resources configured for the URLLC service terminal can multiplex the time-frequency resources in the eMMC service scheduling authorization. Resource multiplexing can ensure that the URLLC service is scheduled and transmitted in time, and in order to ensure the reliability of the URLLC service transmission, in a resource conflict area, a potential processing mode is as follows: URLLC services employ high power transmission, while eMBB services instruct to reduce power transmission or cancel data transmission based on received multiplexed feedback. In order to solve the problem that multiple steps are generally required to reduce the influence when resource reuse occurs, embodiments of the present application provide a communication method to optimize the resource reuse process.
The communication method provided by the embodiment of the application is suitable for a communication system. The communication system includes a base station and a terminal, and fig. 1 shows the structure of the communication system. Referring to fig. 1, the communication system includes a base station 11 and a terminal 12.
The terminal 12 may be a mobile phone or other user equipment, such as a PAD, a palm top computer, a PC, etc. Base station 11 and terminal 12 may be in communication. Therefore, after the terminal 12 obtains the scheduling authorization instruction of the base station 11, according to the existing resource multiplexing process, the base station 11 sends a multiplexing feedback instruction to the terminal 12, the terminal 12 receiving the multiplexing feedback instruction sends transmission data to the base station 11, the base station 11 resends a new transmission/retransmission data scheduling instruction to the terminal for low-priority eMBB service data which is not sent because the time-frequency resource is occupied by the high-priority URLLC service, and the terminal 12 receives the instruction and then performs data transmission again.
The following describes a communication method provided in an embodiment of the present application.
In conjunction with the communication system shown in fig. 1, fig. 2 shows a flow of a communication method provided in an embodiment of the present application. Referring to fig. 2, the method specifically includes the following steps:
in step SO1, the base station determines the location of the newly transmitted/retransmitted data.
Specifically, the terminal requests to transmit transmission data, the base station performs information interaction with the terminal, and finally the position of the transmission data is defined. The new transmission/retransmission data position is represented by an instruction state, the position instruction is an HARQ process number (hybrid automatic repeat request process number), and the base station also determines other identification instructions, wherein the identification instructions comprise NDI, RV and CBGTI; the HARQ process number is used for displaying the time-frequency resource number corresponding to the newly transmitted/retransmitted data; the NDI instruction is used for displaying whether the transmission data is transmitted for the first time; the RV instruction is used for determining the version of the transmission data; the CBGTI is a certain group of data blocks grouped after the data blocks corresponding to the HARQ process number. The NDI is used as one of the eMBB conflict data identifiers, and when resource conflict occurs, the NDI value configured during HARQ process number scheduling needs to be adopted; in order to guarantee the retransmission gain of the service, the base station configures the RV version sequence fixed by the terminal, and the configuration is configured by RRC message. In the first scheduling of the service, the eMBB service terminal and the URLLC service terminal may configure different RV update sequences, which are fixed within a certain time. Because the conflict occurs under any eMB data RV version, the RV updating sequence of conflict data for eMB service scheduling of conflict resources needs to be temporarily allocated by a base station without being restricted by RRC message configuration; the CBGTI can be identified by 0bit, 2bit, 4bit, 6bit, 8bit according to the string length of the data block. For characterizing the specific transmission state of the data block.
Step S02, the base station sends a message to the terminal, where the message includes a multiplexing feedback instruction, a new transmission/retransmission data instruction, and a new transmission/retransmission data location.
Specifically, the base station sends a multiplexing feedback instruction to inform the terminal how to transmit data, and sends a new transmission/retransmission data position to inform the terminal that data transmission is performed according to the instruction position when receiving the new transmission/retransmission data instruction.
Further, the multiplexing feedback instruction includes reducing power transmission and canceling data transmission. Specifically, the multiplexing feedback instruction indicates the state through a Cancellation Indication instruction; the Cancellation Indication is an identification area of a message format, and uses 1bit to perform status Indication, which is used for indicating that the multiplexing feedback instruction is used for canceling data transmission or reducing power data transmission.
In a specific embodiment, when the Indication state of the Cancellation Indication is 1, it indicates that the multiplexing feedback instruction is to cancel data transmission; when the Indication state of the Cancellation Indication is 0, it indicates that the multiplexing feedback command is a power down transmission.
Further, when the multiplexing feedback command is a reduced power transmission, the message sent by the base station to the terminal includes: and multiplexing the feedback command, the new transmission/retransmission data command and the new transmission/retransmission data position to the terminal. In a specific embodiment, when the Indication state of the multiplexing feedback instruction Cancellation Indication sent by the base station is 0, it indicates that the base station adopts a power-down transmission mode to process the problem of resource multiplexing, and meanwhile, since the base station synchronously sends a new transmission/retransmission data instruction and a new transmission/retransmission data position, the terminal transmits according to the new transmission/retransmission data position linked by the new transmission/retransmission data instruction. Wherein, the new transmission/retransmission data position is the process linked by the HARQProcess number.
In a specific embodiment, the multiplexing feedback command is reduced power transmission, and the terminal selects to process the data of the CBGTI data block according to a new transmission/retransmission position (HARQ process number linked process), or only processes the HARQ process number process.
Further, when the multiplexing feedback command is to cancel data transmission, the determining, by the base station, the location of newly transmitted/retransmitted data includes: a first position and a second position. Here, the first position is an original position of newly transmitted/retransmitted data, and the second position is a retransmission position of newly transmitted/retransmitted data.
Specifically, when the Indication state of the multiplexing feedback instruction Cancellation Indication sent by the base station is 1, it indicates that the base station adopts a data transmission Cancellation manner to process the problem of resource multiplexing, and the adoption of the manner needs to make sure the original position and the retransmission position of newly transmitted/retransmitted data, so as to ensure that information is not lost. The method comprises the steps of representing an original position of newly transmitted/retransmitted data by a first position; and characterizing the retransmission position of the newly transmitted/retransmitted data by the second position.
Further, when the multiplexing feedback instruction is to cancel data transmission, the message sent by the base station to the terminal includes: multiplexing the feedback command, the new transmission/retransmission data command, the first location and the second location. Specifically, when the multiplexing feedback instruction sent by the base station is to cancel data transmission, because the base station synchronously sends a new data transmission/retransmission instruction, a first position and a second position, the terminal cancels data transmission at the first position according to the new data transmission/retransmission instruction, and transmits new data transmission/retransmission according to the second position.
In a specific embodiment, as shown in fig. 3, by grouping the existing HARQ process numbers, when any terminal performs service data transmission, the HARQ process number used for corresponding time-frequency resource service scheduling is preferentially selected from the HARQ process number set. When any terminal generates service conflict, the HARQ process number1 used by the corresponding time-frequency resource service scheduling is selected from the HARQ process number set 1. Specifically, when the multiplexing feedback command is to cancel data transmission after the uplink service multiplexing is triggered (that is, the base station suddenly receives a scheduling request sent by a URLLC service terminal with a high priority), the first location corresponds to the HARQ process number, and the second location corresponds to the HARQ process number 1.
In a specific embodiment, the multiplexing feedback command is to cancel data transmission.
When the transmission data sent by the terminal is newly transmitted data, the terminal cancels the transmission of the data corresponding to the CBGTI digital block in the first position (HARQ process number); and a Process linked to according to the second location (HARQ Process number1), under which the cancelled transmission data is combined with other data of the terminal and transmitted.
When the transmission data sent by the terminal is retransmission data, the terminal cancels the transmission of the data corresponding to the CBGTI data block in the first position (HARQ process number); the Process linked to by the second position (HARQ Process number1) transmits the cancelled data in the same area of CBGTI under the Process, while the area not indicated by CBITI transmits other data of the terminal.
In summary, the present application discloses a communication method, which is specifically applied to a resource multiplexing process in which a high service terminal occupies a low service terminal, optimizes a conventional processing manner, and combines a multiplexing feedback instruction and a transmission instruction of newly transmitted/retransmitted data into a data instruction, so that signaling transmission contents are partially redundant, extra signaling consumption is reduced, and system resources consumed by signaling transmission are avoided.
