Description

Information feedback method for uplink data and related equipment

This application claims priority to Chinese Patent Application No. 201610664990.8, entitled "Information Feedback Method for Uplink Data and Related Equipment", filed on August 11, 2016, the entire contents of which are incorporated by reference. In this application.

Technical field

The present invention relates to the field of communications technologies, and in particular, to an information feedback method for uplink data and related devices.

Background technique

With the rapid development of mobile services, the current wireless communication technologies such as the fourth generation mobile communication technology featuring OFDM have been unable to meet the needs of new scenarios. Research on the fifth generation (5G) mobile communication technology has been vigorously carried out in academia and industry. However, the research and standardization of next-generation mobile communication technologies needs to be continuously evolved over a long period of time to meet different scenarios. Therefore, in the initial stage of standardization, how to ensure that the current standardized technical solutions will not evolve. The design of technical solutions that may arise in the process is an obstacle that needs to be focused on, that is, the current standardization process needs to focus on forward compatibility.

The fifth generation of mobile communication technology needs to support ultra-high data transmission rates, massive number of connections and low data transmission delays to meet the needs of different scenarios. The main scenarios of 5G mobile communication in the future include the following three types: enhanced mobile broadband (eMBB), Massive Machine Type Communications (mMTC) and high-reliability low-latency communication (Ultra-Reliable and Low). Latency Communications, URLLC). These three scenarios are different for the type of business, and their needs are different. For example, the eMBB service is mainly for a service scenario that requires a higher data rate; the mMTC service is mainly for a large number of connected service scenarios; the URLLC service is mainly for a service scenario with a delay requirement and a high reliability. In some scenarios of 5G mobile communication, the delay of the data packet for the user plane needs to be in the millisecond (ms) level, so it is required to support transmission with less effort.

In the design of the traditional Long Term Evolution (LTE) system, in order to ensure the reliability of data transmission, a Hybrid Automatic Repeat ReQuest (HARQ) mechanism is introduced: for an uplink transmission packet. After receiving the data packet, the base station performs ACK/NACK (acknowledgement/non-acknowledgement) feedback at a predetermined subframe position. As shown in FIG. 1, the terminal transmits an uplink packet on the nth subframe, and the base station will perform feedback of the ACK/NACK information on the n+4th subframe. Therefore, there is a 4 ms delay in the data transmission and the corresponding feedback time in the HARQ mechanism of the conventional LTE downlink transmission. The design of this delay is mainly to simplify the traditional terminal design and consider the terminal processing capability. However, this design cannot be applied to some scenarios in the 5G that require high latency, such as URLLC.

Referring to FIG. 1 , in an embodiment of the present invention, an information feedback method for uplink data is provided, including:

Step 101: Generate response feedback indication information corresponding to the uplink data packet, where the response feedback indication information is used to indicate a time-frequency location of the ACK/NACK information feedback for the uplink data packet.

Step 102: Determine, according to the response feedback indication information, a time-frequency location of ACK/NACK information feedback for the uplink data packet.

Step 103: Feed back ACK/NACK information for the uplink data packet at the determined time-frequency location.

The time-frequency position of the ACK/NACK information feedback for the uplink data packet may be the location of one downlink subframe, or may be the smallest physical medium that a data packet can map within the limited time-frequency resource. Resource block. In all embodiments of the present invention, within the limited time-frequency resource, the smallest physical resource block that a data packet can map is defined as a minimum transmission unit, and the limited time is defined as a transmission interval. It can be understood that, within one transmission interval, a plurality of the minimum transmission units may be included, and each of the minimum transmission units may be used for transmission of uplink or downlink data. If there is a minimum transmission unit for uplink transmission and downlink transmission in the same transmission interval, a minimum transmission unit needs to be set as a guard interval to implement conversion of uplink transmission and downlink transmission.

Referring to FIG. 2, in the embodiment of the present invention, the method proposed in the embodiment of the present invention is explained by taking six minimum transmission units in one transmission interval as an example, and the transmission interval includes three downlink transmissions. The minimum transmission unit, 3 minimum transmission units for uplink transmission and 1 minimum transmission unit as guard interval. It should be noted that this is just an example. A transmission interval may contain more or less minimum transmission units, and the number of minimum transmission units used for uplink transmission or downlink transmission may vary. Based on the same principle, the method proposed in the embodiment of the present invention is equally applicable to the case other than the above examples.

According to the above definition, the time-frequency location of the uplink data packet transmission may be a minimum transmission unit for uplink transmission in the transmission interval, and the time-frequency location of the ACK/NACK information feedback for the uplink data packet may be The smallest transmission unit used for downlink transmission within the same transmission interval. Therefore, in the embodiment of the present invention, the response feedback indication information is used to indicate that the base station feeds back ACK/NACK for the uplink data packet on a certain minimum transmission unit after receiving the uplink data packet by the base station. information. It can be understood that the response feedback indication information may be an interval between the transmission of the uplink data packet and a minimum transmission unit that transmits the ACK/NACK information, for example, if the uplink data packet is in a transmission interval of the first The k feedback transmission information may be j. After the base station receives the uplink data packet on the kth minimum transmission unit, the base station may feed back on the k+j minimum transmission unit. And sending, by the acknowledgment feedback indication information, the ACK/NACK information for the uplink data packet to the terminal by using the ACK/NACK information of the uplink data packet.

In an implementation manner, the generating the response feedback indication information corresponding to the uplink data packet includes:

Obtain pre-defined response feedback indication information; or,

Specifically, the feedback time interval of the fixed ACK/NACK information transmission and the uplink data packet transmission may be predefined in the base station side (in this embodiment, the two minimums for transmitting the uplink data packet and for transmitting the ACK/NACK information may be The difference between the number of minimum transmission units between the transmission units or the numbers of the two minimum transmission units is used as the predefined feedback indication information, after the base station receives the uplink data packet on a certain minimum transmission unit, Obtaining the predefined feedback indication information, and feeding back ACK/NACK information for the uplink data packet on a predetermined minimum transmission unit according to the predefined feedback indication information. At the same time, the base station may further notify the terminal by using the system information, the radio resource control signaling, the medium access control signaling, or the physical layer signaling, so that the terminal is received at the corresponding time-frequency location for the ACK/NACK information of the downlink packet. It should be noted that, for uplink packets of different terminals, the feedback time interval notified by the base station may be the same or different. As shown in FIG. 3, if the fixed feedback time interval is defined as two minimum transmission units, and the base station receives uplink data packets on the first, second, and third minimum transmission units, the base station is in the fourth, fifth, respectively. The corresponding ACK/NACK information is fed back on the 6 minimum transmission units.

Specifically, the base station may notify the terminal to receive the time-frequency location of the ACK/NACK information by explicit signaling. For example, the base station may carry the response feedback indication information corresponding to the uplink data packet in the uplink scheduling instruction for the uplink data packet, and further notify the terminal to receive, by using the uplink scheduling instruction, the corresponding time-frequency location for the ACK/NACK information of the uplink packet. Correspondingly, after receiving the uplink scheduling instruction, the terminal obtains the response feedback indication information by parsing the uplink scheduling instruction, and further receives ACK/NACK information at a corresponding location.

Specifically, the response feedback indication information corresponding to the uplink data packet may be determined by using different scrambling sequences. For example, the mapping relationship between the scrambling sequence and the ACK/NACK information feedback time-frequency position may be preset in the base station side and the terminal side, and each scrambling sequence correspondingly maps a response feedback indication information, when the terminal receives the location After the uplink scheduling instruction is described, the response feedback indication information is obtained by parsing the scrambling sequence of the uplink scheduling instruction, so that after the terminal sends the uplink data packet, the terminal may respond according to the response feedback indication information. The ACK/NACK information for the uplink data packet is received on the smallest transmission unit.

Specifically, the base station may have multiple time-frequency resource locations (in this embodiment, corresponding to the minimum transmission unit) that can feed back ACK/NACK information, and the base station may select to feed back ACK/NACK information on one of the time-frequency resource locations. It is also possible to choose to feed back ACK/NACK information on multiple time-frequency resource locations. In the case of feeding back ACK/NACK information on multiple time-frequency resource locations, the terminal needs to detect ACK/NACK information on multiple corresponding time-frequency resource locations. As shown in FIG. 4, the ACK/NACK information corresponding to the uplink data packet received by the base station on the first minimum transmission unit can be fed back on the 4th and 5th minimum transmission units; the base station is in the 2nd and 3rd. The ACK/NACK information corresponding to the uplink data packet received on the minimum transmission unit may be fed back on the sixth minimum transmission unit. In this way, the terminal needs to detect the ACK/NACK information corresponding to the uplink data packet sent on the first minimum transmission unit on the 4th and 5th minimum transmission units; and detect the second information on the 6th minimum transmission unit. The ACK/NACK information corresponding to the uplink data packet transmitted on the third smallest transmission unit.

It can be understood that, in this embodiment, the execution body of the ACK/NACK information feedback method of the downlink data may be a communication device, for example, a base station.

Referring to FIG. 5, in an embodiment of the present invention, a method for feeding back ACK/NACK information of downlink data includes:

Step 501: Acquire acknowledgment feedback indication information corresponding to the uplink data packet, where the acknowledgment feedback indication information is used to indicate a time-frequency location of ACK/NACK information feedback for the uplink data packet.

Step 502: Determine, according to the response feedback indication information, a time-frequency location of ACK/NACK information feedback for the uplink data packet.

Step 503: Receive ACK/NACK information for the uplink data packet according to the determined time-frequency location.

In an implementation manner, the obtaining the response feedback indication information corresponding to the uplink data packet includes:

Obtain pre-defined feedback indication information; or,

Specifically, the feedback time interval of the fixed ACK/NACK information transmission and the uplink data packet transmission may be predefined in the terminal side (in this embodiment, the two minimums for transmitting the uplink data packet and for transmitting the ACK/NACK information may be As the pre-defined feedback indication information, the terminal transmits the uplink data packet on a certain minimum transmission unit by using the minimum transmission unit number between the transmission units or the difference between the numbers of the two minimum transmission units. Pre-defined feedback indication information is provided, and ACK/NACK information for the uplink data packet is received on a predetermined minimum transmission unit according to the predefined feedback indication information. It can be understood that the feedback indication information may also be notified by the base station to the terminal by using system information, radio resource control signaling, media access control signaling, or physical layer signaling. It should be noted that, for uplink packets of different terminals, the feedback time interval notified by the base station may be the same or different.

In an implementation manner, the obtaining the response feedback indication information corresponding to the uplink data packet according to the uplink scheduling instruction includes:

Specifically, the base station may notify the terminal to receive the time-frequency location of the ACK/NACK information by explicit signaling. For example, the base station may carry the response feedback indication information corresponding to the uplink data packet in the uplink scheduling instruction for the uplink data packet, and further notify the terminal to receive, by using the uplink scheduling instruction, the corresponding time-frequency location for the ACK/NACK information of the uplink packet.
