Description

Physical uplink control channel sending method, physical uplink control channel receiving method and related equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and a device for sending and receiving a physical uplink control channel.

Background

In the development and evolution process of a wireless communication system, a 5G New radio interface (NR) system and a Long Term Evolution (LTE) system may be deployed simultaneously on a frequency band below 6 GHz. A terminal operating in an NR and LTE Dual Connectivity (DC) mode transmits an uplink signal only at one frequency point at the same time, so that the terminal cannot transmit a signal at an LTE uplink subframe/slot that has a time overlap with an NR uplink slot. Specifically, as shown in fig. 1, a terminal operating in the DC mode needs to send Acknowledgement (ACK)/Negative Acknowledgement (NACK) of the NR system in time slots labeled "U" and "S" on the NR carrier, so that signals cannot be sent on LTE subframes labeled "1", "2", "6", and "7", which will affect the uplink performance of LTE. Meanwhile, the terminal in the LTE mode adopts an ACK/NACK feedback time sequence of N-4, namely the terminal feeds back the ACK/NACK of the downlink data received in the downlink subframe with the number of N-4 in the uplink subframe with the number of N. In the case shown in fig. 1, the terminal cannot transmit Uplink signals on the subframes "6" and "7" of the LTE Uplink (UL) carrier, and the terminal cannot feedback Downlink signals received on the subframes "2" and "3" of the LTE Downlink (DL) corresponding to ACK/NACK, which seriously affects the LTE Downlink performance. Therefore, for the DC terminal, when the terminal transmits an uplink signal on the NR carrier, the terminal cannot feed back ACK/NACK of downlink data received in all downlink subframes in the LTE mode.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The terms "first," "second," "third," and the like in the description and in the claims, and in the above-described drawings, are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

An embodiment of the present invention provides a communication system, as shown in fig. 2, the communication system includes: a terminal device 10 and a network device 20, the terminal device 10 and the network device 20 being capable of communicating. Specifically, network device 20 may send downlink data to terminal device 10, and terminal device 10 may feed back ACK/NACK of the received downlink data to network device 20 in an uplink.

The network device 20 may be, for example, a base station (eNodeB, eNB); in the fifth Generation communication technology (5th-Generation, 5G), the network device may be a base station (gNB) suitable for NR; in other communication systems, the network device may have other names, which are not illustrated herein. The terminal Device 10 may be, for example, a Mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable Device (e.g., a smart watch (e.g., iWatch), a smart bracelet, a pedometer, etc.), and so on.

Next, a method for transmitting a physical uplink control channel PUCCH according to an embodiment of the present invention is described with reference to the communication system shown in fig. 2. As shown in fig. 3, the PUCCH transmission method may include at least the following steps:

s301: n1 feedback information are determined.

Specifically, the N1 pieces of feedback information correspond to N1 downlink time units, which may be, but are not limited to, subframes, slots, and the like. In the embodiment of the present invention, a time unit is a subframe as an example. The feedback information is used to indicate the state of downlink data received by the terminal device 10 on a certain downlink subframe. Thus, one feedback information corresponds to one downlink time unit. The state of the feedback information includes any one of: ACK, NACK, Discontinuous Transmission (DTX), NACK/DTX (indicated by Y subsequently). Wherein, the ACK indicates that the received downlink data is correct; NACK indicates that the received downlink data is incorrect; DTX means that no downlink data is received; NACK/dtx (y) indicates that the received downlink data is incorrect or that no downlink data is received.

S302: and determining Physical Uplink Control Channel (PUCCH) resources and N2 bits according to the N1 feedback information.

Specifically, PUCCH resources and N2 bits jointly indicate a combination state of N3 feedback information, N1, N2, and N3 are positive integers, and N3 is less than or equal to N1. Wherein N2 is 2.

It can be known that, in the LTE system, there is an ACK/NACK feedback method of PUCCH, that is, a PUCCH format (format)1B method based on Channel Selection (Channel Selection), which is abbreviated as a 1BCS (1B Channel Selection ) method, where the 1BCS method uses 2-bit (bit) information carried by PUCCH format 1B and selects one of several specific PUCCH resources to indicate ACK/NACK information to be transmitted. Accordingly, a specific PUCCH resource and N2 bits may jointly indicate a combined state of N3 feedback information. Wherein the above-mentioned combined state is composed of the state of each feedback information. For example, N3 is 3, and the combined state is a combination of 3 states of the feedback information. N3 is less than or equal to N1, that is, PUCCH resources determined from N1 feedback information and N2 bits may jointly indicate a combination state of N1 feedback information, or may jointly indicate a combination state of partial feedback information of N1 feedback information.

S303: the N2 bits are carried on the PUCCH resource and transmitted to the network device.

Specifically, the terminal device 10 uses the PUCCH resource to carry the N2 bits on the PUCCH resource, and transmits the PUCCH resource to the network device 20. After receiving the N2 bits on the PUCCH resource, the network device 20 determines the combination state of the PUCCH resource and the N3 pieces of feedback information jointly indicated by the N2 bits, and further determines whether data retransmission is required according to the state of each piece of feedback information, thereby improving the reliability of data transmission.

By implementing the embodiment of the invention, when the DC terminal can send the uplink signal on the NR carrier wave, the ACK/NACK of the downlink data received in all downlink subframes in the LTE mode can be fed back at the same time, and the performance of the communication system is improved.

In one possible embodiment, N1 ═ 5. In addition, there are 4 alternative PUCCH resources, and N2 ═ 2. It can be seen that N2 is 2, which means that there are 4 cases of these 2 bits, 11, 10, 01, and 00 respectively, and there may be 4 × 4 — 16 combinations in addition to 4 alternative PUCCH resources, so that different combinations of PUCCH resources and N2 bits may jointly indicate a maximum of 16 combinations of N3 feedback information. It should be noted that a specific PUCCH resource and N2 bits may jointly indicate a combination status of N3 feedback information. The above PUCCH resource and N2 bits jointly indicate any one of the following 16 combination states of N3 feedback information:

the 1 st: n3 is 5, and the combination status of N3 pieces of feedback information is: ACK, ACK.

The 2 nd: n3 is 5, and the combination status of N3 pieces of feedback information is: y, ACK.

And (3) type: n3 is 5, and the combination status of N3 pieces of feedback information is: ACK, Y, ACK.

And 4, the method comprises the following steps: n3 is 5, and the combination status of N3 pieces of feedback information is: y, ACK.

And (5) the following steps: n3 is 5, and the combination status of N3 pieces of feedback information is: ACK, Y.

The 6 th: n3 is 5, and the combination status of N3 pieces of feedback information is: y, ACK, Y.

And 7, the following steps: n3 is 5, and the combination status of N3 pieces of feedback information is: ACK, Y, ACK, Y.

And 8, the method comprises the following steps: n3 is 5, and the combination status of N3 pieces of feedback information is: y, ACK, Y.

And 9, the following steps: n3 is 4, and the combination status of N3 pieces of feedback information is: ACK, Y.

The 10 th: n3 is 4, and the combination status of N3 pieces of feedback information is: y, ACK, Y.

The 11 th: n3 is 4, and the combination status of N3 pieces of feedback information is: ACK, Y, ACK, Y.

And 12 th: n3 is 4, and the combination status of N3 pieces of feedback information is: y, ACK, Y.

The 13 th: n3 is equal to 3, and the combination status of N3 pieces of feedback information is: ACK, Y.

14 th: n3 is equal to 3, and the combination status of N3 pieces of feedback information is: y, ACK, Y.

The 15 th: n3 is equal to 3, and the combination status of N3 pieces of feedback information is: ACK, Y.

The 16 th: n3 is equal to 3, and the combination status of N3 pieces of feedback information is: y, Y, Y and not DTX, Y, or the combined state of N3 pieces of feedback information is Y, Y, Y and not DTX, DTX.

It can be known that, when N3 is 3 and the combination status of N3 feedback information is DTX, Y, or DTX, and DTX, terminal device 10 does not send ACK/NACK feedback information to network device 20, that is, terminal device 10 does not select PUCCH resources, and does not send N2 bits to network device 20.

In another possible embodiment, each of the 16 combination states of N3 feedback information is jointly indicated by one PUCCH resource and N2 bits. As can be seen from the above description in the embodiment, 16 different combinations of PUCCH resources and N2 bits exist, and a combination of a specific PUCCH resource and N2 bits corresponds to a specific combination state of N3 pieces of feedback information. Specifically, fig. 4 shows the specific correspondence relationship between different combination states of N3 pieces of feedback information and PUCCH resources and N2 bits.

Wherein the content of the first and second substances,

represents PUCCH resources 1,

Represents PUCCH resource 2,

Represents PUCCH resources 3,

Representing PUCCH resource 4.

It should be noted that the correspondence relationship between the combination status of the N3 pieces of feedback information and the PUCCH resource and the N2 bits is not limited to the relationship shown in fig. 4, and other correspondence relationships may be used in a specific implementation, and the correspondence relationship may be configured in advance in the terminal device 10 and the network device 20. However, selection of the PUCCH resource requires selection from PUCCH resources indicated in Downlink Control Information (DCI) of Downlink data transmitted from the network device 20 to the terminal device 10. If N3 is equal to 3, 3 pieces of feedback information feed back the status of downlink data received in

downlink subframes

2, 3, and 4, respectively. Indicating that the PUCCH resource is resource 1 in downlink control information corresponding to the downlink data received by the downlink subframe 2; indicating that the PUCCH resource is resource 2 in downlink control information corresponding to the downlink data received by the downlink subframe 3; if the PUCCH resource is indicated as resource 3 in the downlink control information corresponding to the downlink data received in the downlink subframe 4, the selection of the PUCCH resource should be selected from resource 1, resource 2, and resource 3.

In another possible embodiment, in the above 16 combined states of N3 feedback information, when N3 is smaller than N1, the states of the N3+1 th to N1 th feedback information may also be regarded as any state (any), that is, the state of the N3+1 th feedback information may be any one of ACK, NACK, DTX, and Y. Then, the PUCCH resource and N2 bits jointly indicate a combined state of N1 feedback information.

For example, when N1 is 5, N3 is 4, and the combination status of N3 pieces of feedback information is ACK, Y, it may be equivalent to N1 is 5, N3 is 5, and the combination status of N3 pieces of feedback information is ACK, Y, any. When N1 is 5, N3 is 3, and the combination status of N3 pieces of feedback information is ACK, Y, it may be equivalent to N1 is 5, N3 is 5, and the combination status of N3 pieces of feedback information is ACK, Y, any, and Y.

By implementing the embodiment of the invention, one uplink subframe can simultaneously feed back the ACK/NACK feedback information of 5 downlink subframes, the use scene is more clear, and 3 bits in the 5 bits can be bound, so that the terminal equipment can adopt a PUCCH format 1b selected based on a channel, the reliability of the ACK/NACK feedback information transmission is improved, and the reliability of a communication system is further improved.

In one possible embodiment, N1 ═ 6. In addition, there are 4 alternative PUCCH resources, and N2 ═ 2. It can be seen that N2 is 2, which means that there are 4 cases of these 2 bits, 11, 10, 01, and 00 respectively, and there may be 4 × 4 — 16 combinations in addition to 4 alternative PUCCH resources, so that different combinations of PUCCH resources and N2 bits may jointly indicate a maximum of 16 combinations of N3 feedback information. It should be noted that a specific PUCCH resource and N2 bits may jointly indicate a combination status of N3 feedback information. The above PUCCH resource and N2 bits jointly indicate any one of the following 16 combination states of N3 feedback information:

the 1 st: n3 is 6, and the combination status of N3 pieces of feedback information is: ACK, or ACK, DTX.

The 2 nd: n3 is 6, and the combination status of N3 pieces of feedback information is: y, ACK or Y, ACK, DTX.

And (3) type: n3 is 6, and the combination status of N3 pieces of feedback information is: ACK, Y, ACK or ACK, Y, ACK, DTX.

And 9, the following steps: n3 is 5, and the combination status of N3 pieces of feedback information is: ACK, Y.

The 11 th: n3 is 5, and the combination status of N3 pieces of feedback information is: ACK, Y, ACK, Y.

And 12 th: n3 is 5, and the combination status of N3 pieces of feedback information is: y, ACK, Y.

The 16 th: n3 is 4 or 3, and the combination status of N3 pieces of feedback information is: the combination state of Y, ACK, Y or Y, Y, Y and N3 feedback information is not DTX, Y for discontinuous transmission, or the combination state of N3 feedback information is Y, ACK, Y or Y, Y, Y and the combination state of N3 feedback information is not DTX, DTX.

In another possible embodiment, each of the 16 combination states of N3 feedback information is jointly indicated by one PUCCH resource and N2 bits. As can be seen from the above description in the embodiment, 16 different combinations of PUCCH resources and N2 bits exist, and a combination of a specific PUCCH resource and N2 bits corresponds to a specific combination state of N3 pieces of feedback information. Specifically, fig. 5 shows the specific correspondence relationship between different combination states of N3 pieces of feedback information and PUCCH resources and N2 bits.

Wherein the content of the first and second substances,

represents PUCCH resources 1,

Represents PUCCH resource 2,

Represents PUCCH resources 3,

Representing PUCCH resource 4.

It should be noted that the correspondence relationship between the combination status of the N3 pieces of feedback information and the PUCCH resource and the N2 bits is not limited to the relationship shown in fig. 5, and other correspondence relationships may be used in a specific implementation, and the correspondence relationship may be configured in advance in the terminal device 10 and the network device 20. However, for selection of PUCCH resources, reference may be made to the relevant description in the embodiment of fig. 4, which is not described herein again.

Then, in the above-mentioned 9 th combination state, the combination states of the N3 pieces of feedback information are: ACK, Y, any.

In the 10 th combination status, the combination status of the N3 pieces of feedback information is: y, ACK, Y, any.

In the 11 th combination status, the combination status of the N3 pieces of feedback information is: ACK, Y, ACK, Y, any.

In the 12 th combination status, the combination status of the N3 pieces of feedback information is: y, ACK, Y, any.

In the 13 th combination status, the combination status of the N3 pieces of feedback information is: ACK, Y, any or ACK, Y, any, and not ACK, DTX.

In the 14 th combination status, the combination status of the N3 pieces of feedback information is: y, ACK, Y, any or Y, ACK, Y, any, and not Y, ACK, DTX.

In the 15 th combination state, the combination states of the N3 pieces of feedback information are: ACK, Y, any or ACK, Y, any, and not ACK, Y, ACK, DTX.

In the 16 th combination status, the combination status of the N3 pieces of feedback information is: y, ACK, Y, any or Y, any, and not Y, ACK, DTX.

It can be known that when the combined state of the N3 feedback information is DTX, Y, any or DTX, any, terminal device 10 does not send ACK/NACK feedback information to network device 20, i.e. terminal device 10 does not select PUCCH resources, nor sends N2 bits to network device 20.

By implementing the embodiment of the invention, one uplink subframe can simultaneously feed back the ACK/NACK feedback information of 6 downlink subframes, the use scene is more clear, and 4 bits in the 6 bits can be bound, so that the terminal equipment can adopt a PUCCH format 1b selected based on a channel, the reliability of the ACK/NACK feedback information transmission is improved, and the reliability of a communication system is further improved.

In one possible embodiment, the permutation order of the N3 feedback information is determined by their corresponding Downlink Assignment Indicators (DAIs). The DAI information is carried by DCI, the DCI corresponds to data received by the terminal device 10 in downlink time units, and the N3 pieces of feedback information correspond to data received by the terminal device 10 in N3 downlink time units. For example, the DAI value corresponding to the first feedback information in the combined state of N3 feedback information is 1, the DAI value corresponding to the second feedback information in the combined state of N3 feedback information is 2, and so on. It should be noted that, in a certain usage scenario, the maximum DAI value is 4, and at this time, the DAI needs to be cyclically valued, that is, when the DAI value corresponding to the previous feedback information is 4 and the DAI value corresponding to the next feedback information is 1, the DAI value corresponding to the feedback information may be interpreted as 5.

By implementing the embodiment of the invention, the feedback information can be sequenced through the DAI value, so that the network equipment can conveniently and quickly determine the state of the data received by each downlink subframe, further determine whether the data needs to be retransmitted or not, and improve the reliability of the communication system.

In another possible embodiment, the ranking order of the N3 feedback messages is determined by the order of the corresponding N3 downlink time units. For example, for a given uplink subframe, the downlink subframes fed back by the uplink subframe may be numbered as subframe 0, subframe 1, … …, subframe (N1-1) in time order, then the first feedback information in the combined state of N3 feedback information corresponds to subframe 0, the second feedback information in the combined state of N3 feedback information corresponds to subframe 1, and so on, the nth 3 th feedback information in the combined state of N3 feedback information corresponds to subframe N3-1. It is appreciated that N3 is less than or equal to N1.

Based on the above determination of the arrangement order of the feedback information according to the downlink time unit, when N1 is N3 is 5 and N2 is 2, the correspondence relationship between the combination status of N3 feedback information and the PUCCH resource and N2 bits may also be as shown in fig. 6; in the case where N1 ═ N3 ═ 6 and N2 ═ 2, the correspondence between the combination status of N3 feedback information and PUCCH resources and N2 bits may also be as shown in fig. 7. Reference may be made to the related descriptions in the embodiments of fig. 4 and fig. 5, which are not repeated herein.

In another possible embodiment, the terminal device 10 may simultaneously support the above two manners to sequence the N3 feedback information, but only one of the manners may be used to sequence the feedback information during a specific usage process.

Specifically, after determining N1 feedback information, the terminal device 10 may select which way to sort the N1 feedback information according to the received DCI, and if the DCI carries the DAI value, sort the feedback information according to the DAI value corresponding to each feedback information, where the specific sorting method refers to the foregoing related embodiments and is not described herein again. If the DCI does not carry the DAI value, the feedback information is sorted according to the time sequence of the downlink subframe corresponding to the feedback information, and the specific sorting method may refer to the foregoing related embodiments and is not described herein again.

It should be noted that the terminals in all the embodiments are DC terminals, that is, the terminals can access NR and LTE simultaneously, and the downlink time unit is a time unit in the LTE mode, and the downlink time unit is a time unit of the same cell.

By implementing the embodiment of the invention, the feedback information can be sequenced through the sequence of the downlink time units, so that the network equipment can conveniently and quickly determine the state of the data received by each downlink subframe, further determine whether the data needs to be retransmitted or not, and improve the reliability of the communication system.

It should be noted that the combination status of N3 pieces of feedback information provided in the embodiment of the present invention is not limited to the combination status provided in the above embodiment when N1 is 5 or 6, and may also be another combination status in the actual use process, which is not limited herein.
