Description

Information transmission method and communication device

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information transmission method and a communication apparatus.

Background

In New Radio (NR), Downlink Control Information (DCI) may instruct a terminal device to transmit a Semi-Static (Semi-Static) Hybrid Automatic Repeat reQuest (HARQ) Acknowledgement (ACK) Codebook (Codebook) at a specific time slot after receiving data traffic on a Physical Downlink Shared Channel (PDSCH). In particular, the DCI may indicate one K1 value of a set of K1 values, thereby instructing the terminal device to transmit the semi-static HARQ-ACK codebook at a slot that is spaced from the slot of the PDSCH by the K1 value slots. The semi-static HARQ-ACK codebook is transmitted through a Physical Uplink Control Channel (PUCCH). Each K1 value in the set of K1 values is used to indicate a slot interval between a slot corresponding to a PDSCH and a slot corresponding to a PUCCH. The values of each K1 value and the number of values of K1 values in the K1 value set are configured or fixed by the access network device. For example, if the PDSCH is scheduled using DCI format 1_1/1_2, the set of K1 values is configured by higher layer signaling. If PDSCH is scheduled in DCI format 1_0, the set of K1 is fixed to {1,2,3,4,5,6,7,8 }.

In some cases, such as Time Division Duplex (TDD) systems, the K1 value set may be configured to have several values in order to satisfy a specific uplink and downlink Time slot configuration.

For example, fig. 1 is a schematic diagram illustrating a terminal device transmitting a PUCCH in a TDD system. In fig. 1, a time slot 0 is a downlink time slot, and a terminal device may receive PDSCH 1; slot 2 uplink slot, the terminal device may send PUCCH1, where PDSCH1 corresponds to PUCCH1, and so on. Wherein, whether the time slot is an uplink time slot or a downlink time slot is determined by the access network equipment. DCI corresponding to PDSCH1 may instruct the terminal device to transmit PUCCH1 in a slot 2 slot intervals apart from a slot corresponding to PDSCH 1; DCI corresponding to PDSCH2 may instruct the terminal device to transmit PUCCH2 in a slot 1 slot apart from a slot corresponding to PDSCH 2; the DCI corresponding to PDSCH3 may instruct the terminal device to transmit PUCCH3 in a slot 3 slot intervals apart from the slot corresponding to PDSCH 3. Therefore, the K1 value set should have at least 3 values {2, 1, 3 }. The DCI corresponding to a PDSCH may indicate that the terminal device transmits the PUCCH corresponding to the PDSCH in n slot intervals of the PDSCH, where n is included in the K1 value set. How to provide the performance of information transmission around the K1 value set becomes a hot issue of research.

In order to reduce the number of bits of the semi-static HARQ ACK codebook and improve the channel transmission performance, embodiments of the present application provide an information transmission method and apparatus, and details of the information transmission method and apparatus provided in the embodiments of the present application are further described below.

Referring to fig. 3, fig. 3 is a schematic flow chart of an information transmission method according to an embodiment of the present application. The information transmission method includes operations 310 through 330 as follows. The main body for executing the method shown in fig. 3 may be a terminal device, or the main body may be a chip in the terminal device. When the terminal device executes the flow shown in fig. 3, the following steps may be included:

310. and acquiring a target K1 value, wherein the target K1 value is used for indicating the interval of the logic time slots between the time slot corresponding to the target uplink channel and the time slot corresponding to the PDSCH.

In one possible implementation, before obtaining the target K1 value, the terminal device needs to obtain a set of K1 values that includes the target K1 value. Specifically, the terminal device may receive higher layer signaling sent by the access network device, where the higher layer signaling is used to configure the set of K1 values. The terminal device may obtain the set of K1 values from the higher layer signaling. Wherein the set of K1 values includes at least one logical slot interval. The number of the at least one logical time slot interval comprised in the set of K1 values may be configured by the access network device.

Wherein the logical time slot satisfies any one or more of the following conditions:

firstly, the number of continuous symbols used for uplink transmission in the logical time slot is greater than M, M is an integer greater than 0, and M is configured by access network equipment;

secondly, the symbols in the logical time slot meet a preset symbol pattern, and the preset symbol pattern is configured by the access network equipment;

and thirdly, the logical time slot comprises symbols used for transmitting a Physical Uplink Control Channel (PUCCH), and the PUCCH is used for transmitting a Semi-Static (Semi-Static) HARQ-ACK codebook.

In one possible implementation, before obtaining the target K1 value, the terminal device needs to determine the target K1 value from the set of K1 values. Specifically, the terminal device may receive Downlink Control Information (DCI) sent by the access network device, where the DCI may be used to indicate a target K1 value in a set of K1 values. The terminal device can determine the target K1 value from the set of K1 values according to the DCI.

Optionally, the terminal device may further determine a time slot corresponding to the PDSCH according to the DCI. The DCI may be used for the access network device to schedule the terminal device to receive downlink data information sent by the access network device on the PDSCH. Therefore, after receiving the DCI, the terminal device may determine the timeslot corresponding to the PDSCH.

320. And determining a target logical time slot according to the target K1 value and the time slot corresponding to the PDSCH, wherein the target logical time slot is the time slot corresponding to the target uplink channel.

Wherein, the logical time slot interval between the target logical time slot and the time slot corresponding to the PDSCH is the target K1 value. The target logical time slot belongs to a logical time slot, that is, the target logical time slot satisfies any one or more of the above-mentioned conditions of being a logical time slot.

Specifically, after determining the target K1 value and the time slot corresponding to the PDSCH, the terminal device detects each time slot after the time slot corresponding to the PDSCH one by one, and detects whether each time slot is a logical time slot. Determining whether a slot is a logical slot may include the following three methods:

optionally, for a timeslot, if the terminal device detects that the number of continuously available symbols in the timeslot is greater than M, it may be determined that the timeslot is a logical timeslot. The available symbols refer to symbols that can be used for uplink transmission, that is, the terminal device may transmit the semi-static HARQ-ACK codebook through the PUCCH on the available symbols. And whether a symbol can be used for uplink transmission may be determined according to a time domain resource allocation table. For example, M is configured to be 3, and as shown in fig. 4, is a diagram illustrating an available symbol condition of the first slot. Symbol 5, symbol 6, and symbol 7 in the first slot are all available, the terminal device may determine that the first slot is a logical slot.

Optionally, for a timeslot, the terminal device may determine whether a symbol pattern of the timeslot matches a preset symbol pattern configured by a high-level signaling, and if so, determine that the timeslot is a logical timeslot. Wherein, the high layer signaling is sent by the access network equipment. The high layer signaling may use a bitmap (bitmap) mode to make a one-to-one correspondence between a preset symbol pattern and each symbol in the timeslot. The preset symbol pattern is expressed in a bitmap manner, and if all symbols corresponding to bits of 1 in the preset symbol pattern are available, the terminal device may determine that the timeslot is a logical timeslot. For example, fig. 5 is a diagram illustrating an available symbol condition of the second slot. Assume that the predetermined symbol pattern is 00000011000000, i.e., the predetermined symbol pattern indicates that the available slots for symbol 6 and symbol 7 are logical slots. And the available symbols in the second slot are symbol 5 and symbol 6, and the preset symbol pattern does not match, the terminal device may determine that the second slot is not a logical slot. The terminal device may determine the second slot as a logical slot only if

symbols

6 and 7 are available in the second slot.

Optionally, for a slot, the access network device may configure the slot for transmitting the PUCCH through high-layer signaling, and if there is an available symbol in the slot, the terminal device may determine that the slot is a logical slot. That is, the access network device may configure in the slot, and the terminal device may transmit the semi-static HARQ-ACK codebook using the PUCCH resource in the slot, and when there is an available uplink symbol in the slot, the slot may be determined as a logical slot.

And the terminal equipment can determine the target logical time slot after paying attention to detection on each time slot after the time slot corresponding to the PDSCH according to the three methods. The following describes a method for determining a target logical time slot with reference to a specific example.

Fig. 6 is a schematic diagram illustrating that a terminal device transmits a PUCCH according to a target K1 value. Wherein the target K1 value is determined to be 1.

For example, when the terminal device receives PDSCH4 in slot 9, the terminal device needs to determine a target logical slot with a logical slot interval of 1 from slot 9 according to the target K1 value of 1. If the terminal device detects that the time slot 10 does not satisfy the logical time slot condition, it will further detect the time slot 11. And slot 11 is a logical slot, the terminal device may determine the slot 11 bits target logical slot, and may send the semi-static HARQ-ACK codebook through PUCCH4 on slot 11.

For another example, when the terminal device receives PDSCH5 in slot 12, the terminal device needs to determine a target logical slot with a logical slot interval of 1 from slot 12 according to the target K1 value of 1. If the terminal device detects that the slot 13 is a logical slot, it determines that the slot 13 is the target logical slot, and may send a semi-static HARQ-ACK codebook through the PUCCH5 on the slot 13.

For another example, when the terminal device receives PDSCH6 in slot 14, the terminal device needs to determine a target logical slot according to the target K1 value of 1, and the logical slot interval between the target logical slot and slot 14 is 1. If the terminal device determines that the time slot 15 and the time slot 16 are not logical time slots, and the time slot 17 is a logical time slot, it may be determined that the time slot 17 is a target logical time slot. The terminal device may transmit the semi-static HARQ-ACK codebook through PUCCH6 on slot 17.

As can be known from the above three examples, the target K1 value may indicate, by taking 1 value, the terminal device to transmit the semi-static HARQ-ACK codebook in a time slot with a different time slot interval from the time slot corresponding to the PDSCH. Then the set of K1 values would require at least the configured values of {1} in the example shown in fig. 6, and the number of configured values would be less than the set of K1 values would require at least the configured values of {1,2,3} in the example shown in fig. 1. In this way, after the value configured in the K1 value set is reduced, the number of bits of the semi-static HARQ-ACK codebook is also reduced.

330. And sending a semi-static hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook to the access network equipment through a target uplink channel, wherein the semi-static HARQ-ACK codebook corresponds to the PDSCH.

After the terminal device determines the target logical time slot, the terminal device may send the semi-static HARQ-ACK codebook to the access network device through the target uplink channel at the target logical time slot. The target uplink channel may be a PUCCH, and the semi-static HARQ-ACK codebook is used to feed back whether downlink data is completely received on the received PDSCH.

By the embodiment of the application, after acquiring the target K1 value, the terminal device may determine the target logical time slot according to the target K1 value and the time slot corresponding to the PDSCH received by the terminal device. The target K1 value may indicate an interval of logical time slots between a time slot corresponding to a target uplink channel and a time slot corresponding to the PDSCH. Because the K1 value in the K1 value set indicates the logical time slot interval, a smaller number of K1 values can indicate more time slot intervals, and the number of K1 values configured in the K1 value set is reduced, so that the bit number of the semi-static HARQ-ACK codebook is reduced, and the channel transmission performance is improved.

Referring to fig. 7, fig. 7 is a schematic unit diagram of a communication device according to an embodiment of the present disclosure. The communication device shown in fig. 7 may be used to perform some or all of the functions in the method embodiment described above with respect to fig. 3. The device may be a terminal device, or a device in the terminal device, or a device capable of being used in cooperation with the terminal device.

The logical structure of the apparatus may include: an acquisition unit 710, a processing unit 720 and a transceiving unit 730. When the apparatus is applied to a terminal device, wherein:

an obtaining unit 710, configured to obtain a set of K1 values, where the set of K1 values includes: at least one time interval value, wherein the at least one time interval value is used for indicating the interval of a logic time slot between a time slot corresponding to a target uplink channel and a time slot corresponding to a Physical Downlink Shared Channel (PDSCH);

a processing unit 720, configured to determine a target logical time slot according to the K1 value set and a time slot corresponding to the PDSCH, where the target logical time slot is a time slot corresponding to a target uplink channel;
