Description

Information transmission method and device

Technical field

This application relates to the field of communications, and in particular to an information transmission method and device.

Background technique

In a communication system, usually one downlink control information (DCI) can schedule one transport block (TB). The transmission block can be carried on a data channel, and the data channel can be a physical downlink data channel or a physical uplink data channel. In order to reduce the overhead of DCI transmission and save transmission resources, as shown in Figure 1, one DCI can schedule multiple transmission blocks. When a DCI schedules multiple transport blocks, DCI needs to indicate the number of scheduled TBs, whether the scheduled TB is new or retransmitted, and the hybrid automatic retransmission request (HARQ) used by the scheduled TB Process number (process number), HARQ process number may also be called HARQ process index (process index).

For example, when one DCI schedules 8 transmission blocks, a bitmap can be used to indicate the scheduled transmission blocks and indicate whether each transmission block is successfully received, so that a maximum of 8+8=16 bits of indication overhead is required. Exemplarily, Figure 2 shows an 8-bit bitmap indicating that each TB is scheduled. 1 can indicate that it is scheduled, and 0 can indicate that it is not scheduled, that is, the scheduled TB blocks are TB2, TB3, and TB5. , TB6, TB8. Fig. 3 shows the initial transmission or retransmission of each TB. 0 can indicate retransmission, and 1 can indicate initial transmission, that is, all scheduled TB blocks are initial transmission.

When another example, a DCI 8 transmission scheduling blocks, each transport block has three states, i.e., the transport block is a new transmission, there is no transmission or retransmission, the transport block 8 total ³⁸ states in combination, since ²¹² <3 ⁸ <2 ¹³ , so at least 13 bits are required to indicate the ³⁸ states of the 8 transport blocks.

The above-mentioned DCI scheduling method for multiple TBs causes a large DCI bit overhead, especially for high-reliability control channel performance, too much bit overhead requires more transmission resources.

Summary of the invention

The embodiments of the present application provide an information transmission method and device, which can reduce the bit overhead when DCI schedules multiple transmission blocks.

In a first aspect, an embodiment of the present application provides an information transmission method, including: a first device receives control information sent by a second device; the first device determines the number of first transmission blocks according to the control information; wherein, the number of first transmission blocks is The number is an element in the first transport block number set, the first transport block number set includes one or more transport block numbers, and the first transport block number set is a set of multiple transport block number sets , Each transmission block number set in the multiple transmission block number sets is associated with a repetition number set, and the repetition number sets associated with different transmission block number sets are different; the first device determines the first repetition number according to the control information, The first repetition number is an element in the repetition number set associated with the first transmission block number set; the first device receives the data channel according to the first transmission block number and the first repetition number.

Based on the method provided in the embodiment of the present application, the first device determines the number of the first transmission block and the first repetition number according to the control information, the first transmission block number set where the first transmission block number is located and the first repetition number The first set of repetition times is associated, which reduces the uncertainty of the number of TBs scheduled by the DCI, thereby reducing the overhead of the DCI and improving resource utilization.

In a possible implementation manner, the control information includes first information and second information, the first information is used to indicate the number of first transmission blocks, and the second information is used to indicate the first number of repetitions. In this way, the terminal device can determine the first transmission block number set corresponding to the first transmission block number according to the first information, determine the first repetition number set according to the first transmission block number set, and determine the first repetition number set according to the second information. Determine the first number of repetitions in the set. Alternatively, the terminal device may determine the number of first transmission blocks according to the first information, determine the first set of repetition times according to the number of the first transmission blocks, and determine the first repetition times in the first set of repetition times according to the second information. In this way, the number of repetitions of the transmission block scheduled by the DCI is limited, the overhead of the DCI can be reduced, and the resource utilization rate can be improved.

In a possible implementation manner, the control information includes third information, and the third information is used to indicate the number of first transmission blocks and the first number of repetitions.

In a possible implementation manner, the number of the first transmission block is T; if T is greater than or equal to R, the first transmission block number set is the second transmission block number set, and the second transmission block number set is associated with the first transmission block number set. The second set of repetition times, the second set of repetition times does not include the first subset of repetition times; if T is less than R, the first transmission block number set is the third transmission block number set, and the third transmission block number set is associated with the first Three sets of repetitions, the third set of repetitions includes the first subset of repetitions; the value of any element in the first subset of repetitions is greater than the value (that is, the value) of the element in the second set of repetitions; where, T is an integer greater than or equal to 1, and R is an integer greater than or equal to 1.

In a possible implementation manner, the number sets of multiple transmission blocks are predefined or configured by the second device. For example, the second device may configure a set of multiple transport block numbers: the second device configures system information or radio resource control (radio resource control, RRC) signaling or media access control control element (media access control control element, High-level signaling configuration such as MAC CE) signaling, or the second device may also configure multiple transport block number sets through physical layer signaling. For example, the physical layer signaling may be downlink control information (DCI).

In a possible implementation manner, multiple sets of repetition times are predefined or configured by the second device. For example, the second device may configure multiple sets of repetition times: the second device may configure multiple repetition times through system information configuration or high-level signaling such as RRC signaling or MAC CE signaling, or the second device may configure multiple repetition times through physical layer signaling. A set of repetition times, for example, the physical layer signaling may be DCI.

In this way, pre-defining or configuring the number M of retransmitted transmission blocks can reduce the combination of the states of the N transmission blocks, thereby reducing the bit overhead of the first information. For example, when N=8 and M=2, the state of the 8 transmission blocks will not be retransmitted at the same time of 3 or more data blocks, which reduces the combination of the states of the 8 transmission blocks, thereby The bit overhead of the first information can be reduced.

In a possible implementation manner, the HARQ process indexes corresponding to the N transport blocks are continuous. Since the HARQ process indexes corresponding to the N transport blocks are continuous, it is not necessary to indicate the HARQ process index corresponding to each transport block one by one, and the bit overhead of the first information can be reduced.

In a possible implementation manner, the HARQ process index of the first transport block in the N transport blocks is predetermined or configured by the second device, and the second transport block to the first transport block in the N transport blocks The HARQ process index of the N transport blocks is determined according to the first rule according to the HARQ process index of the first transport block.

In this way, there is no need to indicate the HARQ process index corresponding to each transport block one by one through the DCI, and the bit overhead of the DCI can be reduced.

In a possible implementation manner, the first rule is predetermined or configured by the second device. For example, the first rule may be to arrange the HARQ process indexes of the second transmission block to the Nth transmission block in ascending order or in descending order.

The present application reduces the uncertainty of the number of TBs scheduled by the DCI by associating the set of the number of transmission blocks with the set of repetitions, thereby reducing the overhead of the DCI and improving resource utilization.

In a possible implementation manner, the control information includes first information and second information, the first information is used to indicate the number of first transmission blocks, and the second information is used to indicate the first number of repetitions.

In a possible implementation manner, the number of the first transmission block is T; if T is greater than or equal to R, the first transmission block number set is the second transmission block number set, and the second transmission block number set is associated with the first transmission block number set. The second set of repetition times, the second set of repetition times does not include the first subset of repetition times; if T is less than R, the first transmission block number set is the third transmission block number set, and the third transmission block number set is associated with the first Three sets of repetitions, the third set of repetitions includes the first subset of repetitions; the value of any element in the first subset of repetitions is greater than the value of the element in the second set of repetitions; where T is greater than or equal to An integer of 1, and R is an integer greater than or equal to 1.

For ease of understanding, the information transmission method provided in the embodiments of the present application will be specifically introduced below in conjunction with the accompanying drawings.

As shown in FIG. 5, an embodiment of the present application provides an information transmission method. The first device is a terminal device, the second device is a base station, and the control information is DCI as an example for description, including:

501. The second device determines control information and sends the control information to the first device.

The control information is used to schedule multiple transmission blocks or transmission blocks carried by multiple data channels.

In a possible design, the control information includes first information and second information, the first information is used to indicate the number of first transmission blocks, and the second information is used to indicate the first number of repetitions. In this way, the terminal device determines the number of transmission blocks scheduled by the DCI and the number of repetitions of the transmission blocks according to the first information and the second information. In another possible design, the control information includes third information, and the third information is used to indicate the number of first transmission blocks and the first number of repetitions. In this way, the terminal device determines the number of transmission blocks scheduled by the DCI and the number of repetitions of the transmission blocks according to the third information.

502. The first device receives control information sent by the second device.

That is, the terminal device receives the DCI sent by the base station, and determines the scheduled transmission block or data channel according to the DCI.

503. The first device determines the number of first transmission blocks and the first number of repetitions according to the control information.

Wherein, the first transmission block number is an element in the first transmission block number set, and the first transmission block number set includes one or more transmission block numbers. The first transport block number set is a set of multiple transport block number sets, each transport block number set in the multiple transport block number sets is associated with a set of repetition times, and the different transport block number sets are The set of associated repetition times is different. The first repetition count is an element in the first repetition count set associated with the first transmission block number set, and each repetition count set includes one or more repetition counts.

Optionally, the first repetition quantity is the repetition quantity of the control information transmission and/or the repetition quantity of the data channel transmission scheduled by the downlink control information. Among them, the data channel is a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH).

It should be noted that there is no intersection between different sets of transmission block numbers. The number of elements included in different transport block number sets is different, or the number of elements included in different transport block number sets is the same but the value of no element in the different transport block number sets is the same.

It should be noted that different sets of repetition times may or may not have intersections. Different sets of repetition times include different numbers of elements, or different sets of repetition times include the same number of elements, but the value of at least one element in different sets of repetition times is different.

For each transport block number set in the multiple transport block number sets, the transport block number set includes one or more transport block number elements. Each transport block number element is used to indicate the number of transport blocks scheduled by the DCI or the number of data channels carrying the transport block. For each repetition number set in the multiple repetition number sets, the repetition number set includes one or more repetition number elements. Each repetition number element can be used to indicate the repetition number of the DCI, or the repetition number of the data channel scheduled by the DCI, or the maximum repetition number of the uplink or downlink data channel configured by the higher layer. Among them, the data channels scheduled by DCI include PUSCH and PDSCH. From the perspective of channel quality analysis, when the channel quality is poor, the scheduled TBs need to be repeated more times. At this time, the number of scheduled TBs needs to be limited, otherwise it will occupy too much resources; when the channel quality is good, scheduling The number of TB repetitions is small, and the number of TBs scheduled at this time can be relatively large, and the scheduling flexibility should be given higher, and the number of scheduled TBs should be more. Since information such as the number of repetitions of the DCI or the number of repetitions of the data channel scheduled by the DCI can reflect the channel quality, the set of transmission block numbers can be associated with the set of repetitions to limit the number of transmission blocks scheduled by the DCI to reduce DCI Expenses to improve resource utilization.

Optionally, the foregoing multiple transmission block number sets are predefined by the first device and the second device or configured by the second device. For example, the second device may configure a set of multiple transport block numbers: the second device configures through system information or high-level signaling such as RRC signaling or MAC CE signaling, or the second device may also configure through physical layer signaling. Configure multiple transport block number sets, for example, the physical layer signaling may be DCI.

Optionally, the foregoing multiple sets of repetition times are predefined by the first device and the second device or configured by the second device. For example, the second device may configure multiple sets of repetition times: the second device may configure multiple repetition times through system information configuration or high-level signaling such as RRC signaling or MAC CE signaling, or the second device may configure multiple repetition times through physical layer signaling. A set of repetition times, for example, the physical layer signaling may be DCI.

Optionally, the control information may schedule one or more transmission blocks. Optionally, the control information is downlink control information (downlink control information, DCI)

Wherein, the first device determining the number of first transmission blocks and the first number of repetitions according to the control information includes at least two implementation manners:

The first implementation is as follows:

The first device determines the number of first transmission blocks according to the control information; then the first device determines the first number of repetitions according to the number of first transmission blocks and the control information.

Specifically, the control information may include first information and second information, the first information is used to indicate the number of first transmission blocks, and the second information is used to indicate the first number of repetitions. The first device determines the number of first transmission blocks according to the first information. Then, the first device determines the first set of repetition times according to the first set of transmission block numbers where the first transmission block number is located. The first device determines the first repetition number in the first repetition number set according to the second information. Alternatively, the terminal device may determine the number of first transmission blocks according to the first information, determine the first set of repetition times according to the number of the first transmission blocks, and determine the first repetition times in the first set of repetition times according to the second information. Alternatively, the terminal device may determine the number of first transmission blocks according to the first information, determine the first set of repetition times according to the first set of transmission block numbers in which the number of first transmission blocks is located, and set the first repetition times according to the second information. Determine the first number of repetitions.

Optionally, the first information may indicate the number of first transmission blocks or the index of the number of first transmission blocks, and the first device may determine the number of first transmission blocks according to the index of the number of first transmission blocks, and then according to the first The number of transmission blocks determines the first transmission block number set where the first transmission block number is located.

Optionally, the second information may indicate the order or index of the first repetition quantity in the first repetition quantity set, so that the first device can determine the first repetition quantity in the first repetition quantity set according to the second information.

In the embodiment of the present application, there is a set of the number of transmission blocks corresponding to the set of repetition times, and the overhead of the DCI can be reduced through the association relationship between the set of number of transmission blocks and the set of repetition times. For example, 1 bit in the DCI is used to indicate the number of the first transmission block or the index of the first transmission block, and 1 bit in the DCI is used to indicate the order of the first repetition number in the first repetition number set. After the first device determines the number of first transmission blocks, it can determine the first set of transmission block numbers. The first device can determine the first set of repetition times according to the first set of transmission block numbers. The first repetition number is determined in the first repetition number set. In this way, the number of repetitions of the transmission block scheduled by the DCI is limited, so that the overhead of the DCI can be effectively reduced.

For example, suppose that the DCI includes two fields, the first field is used to indicate the number of the first transmission block, and the second field is used to indicate the first number of repetitions, where each field may include one or more bits. Assuming that the value of the first field is 4 or the first device determines that the number of first transmission blocks is 4 according to the first field, the first device can determine that the set of the number of first transmission blocks is the set {4,8} where 4 is located, If the set of repetition times associated with the first transmission block number set is {1,2}; if the value of the second field is 0, the first device can determine that the first repetition count is the first in {1,2} The value is 1; if the value of the second field is 1, the first device can determine that the number of first transmission blocks is the second value in {1,2}, which is 2.

In the first implementation manner, different fields in the DCI can be used to indicate the number of first transmission blocks and the first number of repetitions respectively, that is, the first information is used to indicate the number of first transmission blocks, and the second information is used to determine the number of first transmission blocks. The first repetition number in the repetition number set can effectively reduce the DCI overhead.

The second implementation is as follows:

The downlink control information includes third information, and the third information is used to indicate the number of first transmission blocks and the first number of repetitions. The first device determines the number of first transmission blocks and the first number of repetitions according to the third information.

For example, assuming that the DCI includes a field indicating the third information, the field may include one or more bits. If the value of this field is 1, the terminal device can determine that the first transmission block number is 4 in the first transmission block number set {4,8}, and the first repetition count is associated with the first transmission block number set 1 in the set of repetition times {1,2}.

In a possible implementation manner, the number of the first transmission block is T or the maximum value of the element in the first transmission block number set is T. The plurality of transmission block number sets includes at least the second transmission block number set and The third transmission block number set; if T is greater than or equal to R, the first transmission block number set is the second transmission block number set, and the second transmission block number set is associated with the second set of repetitions, and the second set of repetitions Does not include the first repetition count subset, the first repetition count subset includes one or more repetition counts, and the value of any element in the first repetition count subset is greater than any one in the first repetition count subset The value of the element; if T is less than R, the first transmission block number set is the third transmission block number set, the third transmission block number set is associated with the third repetition number set, and the third repetition number set includes the first repetition number Subset; the value of any element in the first repetition number subset is greater than the value of the element in the second repetition number set; where T is an integer greater than or equal to 1, and R is an integer greater than or equal to 1.

For example, when T is less than or equal to 4, the first transport block number set is the second transport block number set, and the second transport block number set is {1,2,3,4}, {1,2 ,3,4} The associated first set of repetition times can be {n1,n2,n3,n4,n5,n6,n7,n8}. Among them, {n1, n2, n3, n4, n5, n6, n7, n8} is the number of data channel repetitions indicated by the downlink control information, and n1<n2<n3<n4<n5<n6<n7<n8, that is, according to Sorting from small to large; when T is greater than 4, the first transmission block number set is the third transmission block number set, and the third transmission block number set is {5,6,7,8}, {5,6, 7,8} The associated first set of repetition times is {n1, n2, n3, n4, n5}; among them, the first subset of repetition times may be {n6, n7, n8}.

In a possible implementation manner, the multiple transmission block number sets include at least a second transmission block number set and a third transmission block number set (here the second transmission block number set or the third transmission block number set The set may be the aforementioned first transmission block number set), and the value of any element contained in the second transmission block number set is less than the value of any element contained in the third transmission block number set; the second The second set of repetition times associated with the set of transmission block numbers includes a second subset of repetition times; the third set of repetition times associated with the third set of transmission block numbers does not include the second subset of repetition times. The value of any element in the second subset of repetition times is greater than the value of any element in the third transmission block number set.

For example, {n1,n2,n3,n4,n5,n6,n7,n8} is the number of data channel repetitions indicated by the downlink control information, and n1<n2<n3<n4<n5<n6<n7<n8, that is In order from small to large, n1, n2, n3, n4, n5, n6, n7, n8 are determined according to the maximum number of data channel repetitions configured by the upper layer; the second transport block number set is {1,2}, { 1,2} The set of repetition times of the associated data channel {n1,n3,n6,n8}; the set of the third transmission block number is {3,4}, and the set of {3,4} repetition times is {n1, n2, n3, n4}; the second subset of repetition times is {n6, n8}.

From the perspective of channel quality analysis, when the channel quality is poor, the scheduled TBs need to be repeated more times. At this time, the number of scheduled TBs needs to be limited, otherwise it will occupy too much resources; when the channel quality is good, scheduling The number of TB repetitions is small, and the number of TBs scheduled at this time can be relatively large, and the scheduling flexibility should be given higher, and the number of scheduled TBs should be more. Since information such as the number of repetitions of the DCI or the number of repetitions of the data channel scheduled by the DCI can reflect the channel quality, the set of transmission block numbers can be associated with the set of repetitions to limit the number of transmission blocks scheduled by the DCI to reduce DCI Expenses to improve resource utilization.

Example 1: The multiple transport block number sets include two transport block number sets, for example, a second transport block number set and a third transport block number set.

Wherein, the value of any element in the second transmission block number set is less than or equal to P, the value of any element in the third transmission block number set is greater than P, and P is an integer greater than zero.
