Description

Method, device and medium for sending and receiving feedback information Technical field

The present disclosure relates to the field of wireless communication technology, and in particular to methods, devices and media for sending and receiving feedback information.

Background technique

The continuous emergence of new Internet applications puts forward higher requirements for wireless communication technology, driving the continuous evolution of wireless communication technology to meet the needs of applications. At present, cellular mobile communication technology is in the evolution stage of a new generation of technology.

IoV communication is also called vehicle to everything (V2x), including the following three communication methods: vehicle-to-vehicle (V2V) communication method, vehicle-to-vehicle (V2V) communication method, and vehicle-to-infrastructure (V2I) ) Communication method, vehicle-to-pedestrian (V2P) communication method. IoV communication technology can effectively improve traffic safety, improve traffic efficiency, and enrich people's travel experience.

Using the existing cellular communication technology to support IoV communications can effectively utilize existing base station deployments, reduce equipment overhead, and is also more conducive to providing quality of service (QoS) guaranteed services to meet the needs of IoV services. Therefore, in the Rel-14/15 of the Long Term Evolution (LTE) technique, the cellular network supports the V2x of the IoV communication, that is, the cellular based V2x (cellular based V2x, C-V2x). In C-V2x, the communication between in-vehicle equipment and other equipment can be transferred through the base station and core network, that is, using the communication link between the terminal equipment and the base station in the original cellular network (such as uplink UL or downlink DL) for communication, or directly through a direct link (sidelink) between devices. Compared with the uplink/downlink, the direct link communication has the characteristics of short delay and low overhead, and is very suitable for direct communication between on-board equipment and other peripheral equipment in close geographical proximity.

V2x sidelink communication in LTE can only support some basic security V2x applications, such as Cooperative Awareness Messages (CAM) or Decentralized Environmental Notification Messages (Decentralized Environmental Notification Message, DENM) and other basic security information (BSM- Basic Safety Message) for voice broadcast communication, etc. Recently, with the development of technologies such as autonomous driving, in order to support new V2x services, new requirements have been put forward for the performance of V2x technology. The use of 5G New Radio (NR) technology to support new V2x communication services and scenarios has been planned by 3GPP as an important content of Rel16. The 3GPP working group has set up some new V2x communication business requirements that need to be met, including fleet management (Vehicles Platooning), Extended Sensors (Extended Sensors), Advanced Driving, and Remote Driving (remote driving). In general, NR V2x sidelink needs to provide higher communication rates, shorter communication delays, and more reliable communication quality.

Detailed ways

The embodiments of the present invention will now be further described with reference to the drawings and specific implementations.

Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

In the discussion of NR V2x, RAN WG1 (RAN1) decided to support the use of the hybrid automatic repeat request (Hybrid) mechanism of the physical layer for unicast and multicast services of direct communication. For HARQ feedback information, the physical layer direct feedback channel (Physical Sidelink Feedback Channel, PSFCH) is used for transmission.

In NR Uu uplink HARQ feedback, the physical uplink control channel (Physical Uplink Control Channel, PUCCH) format 0 (format0) and PUCCH format1 are defined for HARQ feedback of less than or equal to 2 bits; among them, format 0 uses 1 or 2 OFDM time-domain symbols are used for transmission, format 1 uses 4 OFDM time-domain symbols or more for transmission. Considering that NR V2x needs to support many services with strict delay requirements, it is more advantageous to use shorter OFDM time domain symbols.

For the format of NR PUCCH format 0, see TS 38.211 6.3.2.3. Format 0 uses the method of sequence detection to transmit HARQ information. The signal of Format 0 is a sequence with a length of 12, which occupies 1 physical resource block (Physical Resource Block, PRB) frequency domain resources for transmission. The above sequence is obtained by cyclic shifting a base sequence, and different cyclic shift values represent different feedback information.

The way to cyclically shift the base sequence is as follows:

0≤n＜M _ZC ; where α is the value of cyclic shift,

Is the base sequence, and M _ZC is the length of the base sequence.

The cyclic shift value of the PUCCH format0 sequence is:

among them

Is a constant (for example, the number of subcarriers of a PRB is 12), m ₀ is the initial value configured by the base station side for the user equipment,

It is a value generated through a specific pseudo-random sequence according to the time position (that is, the subframe and slot number) where the transmission occurs. The base station knows m _{0 in} advance and can use the same pseudo-random sequence

Different feedback information corresponds to different cyclic shift configuration values m _cs . The corresponding relationship between the feedback information and the cyclic shift configuration value m _cs is as follows (quoted from TS38.213).

Table 9.2.3-3, used to show the mapping relationship between 1 HARQ-ACK information bit in PUCCH format0 and sequence cyclic shift configuration value

Table 9.2.3-3, used to indicate the mapping relationship between the 2 HARQ-ACK information bits in PUCCH format0 and the sequence cyclic shift configuration value

The user equipment sends the cyclic shift sequence after the base sequence is cyclically shifted, and the base station side determines the cyclic shift configuration value of the cyclic shift sequence sent by the user to obtain m _cs , and restores the user’s feedback according to the mapping relationship in the above table information.

The frequency domain bandwidth of NR PUCCH format 0 is a fixed 1PRB. In the V2x scenario, both ends of the communication are moving. Therefore, in this application scenario, it is necessary to deal with more severe channel conditions; and because of the use of distributed scheduling, The interference conditions have also worsened. In addition, NR PUCCH format 0 uses different cyclic shift configuration values to identify NACK or ACK in the feedback information, and the measurement of the cyclic shift configuration value is more sensitive to the impact of delay. Each user equipment in NR Uu adjusts the transmission time forward according to the delay from the user equipment to the base station to ensure that the signal arriving at the base station is not affected by the transmission delay. However, unlike NR Uu, in NR V2x, there is no situation that the central node and the target receiving end of communication are distributed in the entire area, so similar transmission time adjustments are not made. Therefore, the distance between different user equipment will cause different The time delay will affect the measurement accuracy of the cyclic shift configuration value, thereby reducing the reliability of HARQ feedback. The reliability of HARQ feedback requires an order of magnitude higher than that of data, and reducing its reliability will seriously affect the efficiency of data transmission. Therefore, this application proposes a new solution to solve the problem of the transmission delay in NR V2x that causes the impact on the measurement accuracy of the cyclic shift configuration value and reduces the reliability of HARQ feedback.

Fig. 1 is a flowchart showing a method for sending feedback information according to an exemplary embodiment. The method is applied to the first transmission device of two transmission devices. As shown in Fig. 1, the method includes:

Step S11, configure the base sequence to generate N cyclic shift sequences, where N is an integer greater than 1;

Step S12: Send the N cyclic shift sequences to the second device.

The above two transmission devices refer to two transmission devices that communicate through a direct link (sidelink), and are suitable for various direct communication application scenarios. Transmission devices can be various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment ( User Equipment (UE), mobile station (Mobile Station, MS), terminal device (terminal device), etc.

In a possible implementation manner, step S11 includes:

Step S11-1: Determine the relative value or set of relative values of the cyclic shift configuration value corresponding to the feedback information to be transmitted;

Step S11-2, determining the N cyclic shift configuration values according to the relative value or the set of relative values;

Step S11-3: Perform cyclic shift on the base sequence using the N cyclic shift configuration values to obtain N cyclic shift sequences.

The relative value in this method can refer to the difference of the cyclic shift configuration value, or the modulus of the difference between the cyclic shift configuration value and the length of the base sequence, or the function operation of the difference of the cyclic shift configuration value Value, this function operation can be shift, multiple and other operations.

The relative value set includes N-1 relative values, and the N-1 relative values are the relative values between two adjacent cyclic shift configuration values among the N cyclic shift configuration values arranged in sequence. In step S11-2, determining the N cyclic shift configuration values according to the relative value set includes: making the relative values between two adjacent cyclic shift configuration values among the N cyclic shift configuration values correspond to N-1 relative values respectively value.

The feedback channel sent by the user equipment is delayed due to the link quality during the transmission process. The signal delay of the feedback channel causes the effect of adding a fixed offset value to the cyclic shift. In this method, the same user equipment Send at least N cyclic shift sequences to the same target address. The signal delays of these N cyclic shift sequences can be considered to be basically equal. Using the relative value relationship of cyclic shifts can eliminate the influence of signal delay on cyclic shift detection Influence, thereby effectively improving the reliability and transmission efficiency of the feedback channel.

The feedback channel in this method includes but is not limited to HARQ format.

Before step S11-1, the method further includes: setting a mapping relationship set, the mapping relationship set includes a mapping relationship between the value of the feedback information and the relative value of the cyclic shift configuration value or the relative value set; the selection of different feedback information The value corresponds to the relative value or set of relative values of different cyclic shift configuration values. In step S11-1, determining the relative value or relative value set of the cyclic shift configuration value corresponding to the feedback information to be transmitted includes: determining the relative value of the cyclic shift configuration value corresponding to the value of the feedback information to be transmitted according to the mapping relationship set A collection of values or relative values.

This method uses the base sequence of NR PUCCH format0, and the sequence after cyclic shift is shown in formula (1):

among them,

Is the base sequence, M is the length of the base sequence,

Is the cyclic shift value. The cyclic shift configuration value is m _cs . In the following examples, the relative value of the cyclic shift configuration value is based on the difference of the cyclic shift configuration value.

The value of N includes two cases:

The first case: N is 2.

The application method is: the cyclic shift configuration value includes the first cyclic shift configuration value and the second cyclic shift configuration value. The difference between the cyclic shift configuration value refers to the first cyclic shift configuration value and the second cyclic shift configuration value. The difference between the configuration values. Different feedback information values correspond to different differences.

Specific example one

Use the base sequence of NR PUCCH format0, and the length L of this base sequence is 12. Set the value of N to 2.

The sequence after cyclic shift is shown in formula (1).

among them,

Is the base sequence, the cyclic shift value of sequence 1 is

The cyclic shift of sequence 2 is

The first cyclic shift configuration value is

The second cyclic shift configuration value is

Different feedback information values correspond to different differences

When the feedback bit length is 1 bit, the mapping relationship between the feedback information and the difference of the cyclic shift configuration value is shown in Table 1:

Table 1

When the feedback bit length is 2 bits, the mapping relationship between the feedback information and the cyclic shift configuration value difference is shown in Table 2:

Table 2

Specific example two

Compared with the specific example 1, when a longer sequence is used, more frequency domain resources will be occupied, and the difference of the cyclic shift will also change accordingly. In the specific example 2, a sequence with a length of L of 24 is used, which needs to occupy frequency domain resources of 2 PRBs. Use the base sequence of NR PUCCH format0. Take the value of N as 2 as an example.

When the feedback bit length is 1 bit, the mapping relationship between the feedback information and the cyclic shift configuration value difference is shown in Table 3:

table 3

When the feedback bit length is 2 bits, the mapping relationship between the feedback information and the cyclic shift configuration value difference is shown in Table 4:

Table 4:

In the mapping relationships shown in Table 1, Table 2, Table 3, and Table 4, under the same feedback bit length, the difference between the cyclic shift configuration value pairs is L/(2^M) rounded down Integer multiples, where L is the length of the base sequence, M is the number of bits of the feedback information, that is, the difference of the cyclic shift configuration value is uniformly or non-uniformly distributed in the interval from 0 to L-1, and L is the base sequence length. This uniform distribution method can increase the tolerance to detection errors and improve the robustness of the transmission method.

The above-mentioned equal distribution method is a possible implementation in an application scenario, and a non-uniform distribution method is adopted in different application scenarios. For example, when the values of the feedback information in Table 1 are 0 and 1, the difference between the first cyclic shift configuration value and the second cyclic shift configuration value takes other different values. For another example, in Table 2, when the HARQ-ACK values are {0,0}, {0,1}, {1,1}, {1,0}, the first cyclic shift configuration value and the second cyclic shift The difference of the configuration value takes other different values.

The second case: N is greater than 2.

The application method is: the difference set includes N-1 cyclic shift configuration value difference values, which correspond to the difference between two adjacent cyclic shift configuration values among the N cyclic shift configuration values arranged in sequence. In step S11-2, determining the N cyclic shift configuration values according to the difference set includes: making the difference between two adjacent cyclic shift configuration values among the N cyclic shift configuration values correspond to the N-1 respectively The difference between the cyclic shift configuration values. As a possible implementation manner: among the N cyclic shift configuration values arranged in sequence, the difference between two adjacent cyclic shift configuration values is the same.

Specific example three

Use the base sequence of NR PUCCH format0, and the length L of this base sequence is 12. The value of N is 3.

When the feedback bit length is 1 bit, the mapping relationship between the feedback information and the difference of the cyclic shift configuration value is shown in Table 5:

table 5

When the feedback bit length is 2 bits, the mapping relationship between the feedback information and the difference of the cyclic shift configuration value is shown in Table 6:

Table 6

Except as shown in Table 5 and Table 6, setting the difference between adjacent cyclic shift configuration values corresponding to the same feedback information is the same, in other cases, setting the adjacent cyclic shift corresponding to the same feedback information In the difference of the configuration values, the difference of each pair of cyclic shift configuration values is different.

E.g:

When the feedback bit length is 1 bit, the mapping relationship between the feedback information and the difference of the cyclic shift configuration value is shown in Table 7:

Table 7

When the feedback bit length is 2 bits, the mapping relationship between the feedback information and the difference of the cyclic shift configuration value is shown in Table 8:

Table 8

In step S12, sending N cyclic shift sequences to the second device includes one of the following ways:

Manner 1: Divide a section of frequency domain resources on the same time domain resource into N parts, and each cyclic shift sequence occupies one part, and this section of frequency domain resources is continuous or discontinuous.

Fig. 2 is a schematic diagram of a time-frequency resource used to send a cyclic shift sequence. As shown in Fig. 2, taking the value of N as an example, a section of frequency-domain resources at the same time-domain position is divided into two parts. The first cyclic shift sequence occupies the first frequency domain resource, the second cyclic shift sequence occupies the second frequency domain resource, and the two frequency domain resources are continuously distributed in the frequency domain.
